If a person has his own workshop, then one of the most important issues is cleaning the premises. But unlike cleaning dust in an apartment, a regular household vacuum cleaner will not help here, since it is not designed for construction waste and sawdust - its garbage container (dust container or bag) will very quickly become clogged and become unusable. Therefore, they often use a homemade cyclone filter, which, together with a household vacuum cleaner, will help clean the workshop.

Introduction

Wood dust and other technical debris, although it seems harmless at first glance, actually pose many different dangers, both for the master and for the equipment. For example, prolonged work without protective equipment that prevents dust from entering the respiratory system can cause serious complications with the respiratory tract, impair the sense of smell, etc. In addition, a tool that is in the workshop under the influence of dust can quickly fail. This happens because:

1. dust, mixing with lubricant inside the tool, forms a mixture that is completely unsuitable for lubricating moving parts, which results in overheating and further damage
2. dust can make it difficult for the moving parts of the tool to rotate, which leads to additional stress, overheating and failure,
3. dust clogs the air ducts designed to ventilate the heated parts of the tool and remove heat from them, again resulting in overheating, deformation and failure.

Thus, the issue of the quality of removal of sawing products and, in general, cleaning of the premises is very acute. Modern power tools are equipped with systems for removing dust and chips directly from the sawing area, which prevents dust from spreading throughout the workshop. In any case, the dust removal process requires a vacuum cleaner (or chip cleaner)!

There are good ones industrial vacuum cleaners and if possible, it is better to choose the most best option price and quality and buy a construction vacuum cleaner.

However, there are cases when you already have a household vacuum cleaner and it is easier to upgrade it and solve the problem of collecting construction waste indoors. To do this, you need to use a cyclone filter - it can be done in half an hour if all the necessary elements are available.

Operating principle

There are a great many different designs of cyclones, but they all share the same operating principle. All designs of cyclone chip suckers consist of three main parts:

• Household vacuum cleaner
• Cyclone filter
• Waste collection container

Its design is such that the flow of intake air is directed in a circle and it is obtained rotational movement. Accordingly, the construction waste contained in this air flow (these are large and heavy fractions) is acted upon by a centrifugal force, which presses it against the walls of the cyclone chamber and, under the influence of gravity, it gradually settles in the tank.

The disadvantage of a cyclone vacuum cleaner is that in this way you can only collect dry garbage, but if there is water in the garbage, then there will be problems when sucking up such a substance.

The vacuum cleaner must be powerful enough, since in its normal mode of operation it is assumed that air is sucked through a standard hose. If an additional cyclone filter is used, an additional filter appears in the air path, as well as total length the air duct is more than doubled due to the additional air duct. Since the design is as maneuverable as a separate vacuum cleaner, the length of the last hose should be sufficient for comfortable work.

Preparatory work

As mentioned above, you can make a cyclone filter for a workshop in half an hour, but to do this you need to check the availability of everything necessary for the production of a chip blower with your own hands, namely: tools, materials and consumables.

Tools

To carry out the work, the following tools will be needed:

1. electric drill,
2. screwdriver,
3. jigsaw,
4. compass,
5. clamps,
6. Phillips screwdriver,
7. pencil,
8. on wood (50-60mm),
9. kit .

Materials and fasteners

Materials can be used both new and used, so carefully review the list below - you may already have something in stock;

1. The air duct (hose) for a vacuum cleaner is corrugated or in a textile braid.
2. A sewer pipe with a diameter of 50 mm and a length of 100–150 mm, into one of the ends of which the air duct of your household vacuum cleaner should be inserted.
3. Sewer outlet 30 or 45 degrees, 100–200 mm long, into one end of which the air duct specified in paragraph 1 will be inserted.
4. Plastic bucket (“large”) 11-26 liters with a hermetically sealed lid.
5. Bucket (“small”) plastic 5-11 liters. Note. It is important that the difference between the two maximum diameters of the buckets is approximately 60–70 mm.
6. Sheet 15–20 mm thick. Note. The sheet size must be larger than the maximum diameter of the Large Bucket.
7. Wood screws with a flat wide head and a length of 2/3 of the thickness.

Making a cyclone filter

Creating a homemade chip sucker consists of a number of stages:

1. Creating a retaining ring and a shaped insert
2. Installing the Retaining Ring
3. Installing the side pipe
4. Top entry installation
5. Installing a shaped insert
6. Cyclone filter assembly

Creating a retaining ring and a shaped insert

It is necessary to cut off the side of a small bucket, which is used to attach the lid. The result should be a cylinder like this (well, slightly conical).

We make markings - place a small bucket on it and draw a line along the edge - we get a circle.

Then we determine the center of this circle (see school geometry course) and mark another circle, the radius of which is 30 mm larger than the existing one. Then we mark the ring and figured insert, as shown in the picture.

Installing the Retaining Ring

We fix the ring on the edge of a small bucket so that we get a side. We fasten using self-tapping screws. It is advisable to pre-drill the holes to avoid splitting.

We mark the roof of a large bucket. To mark, you need to place the bucket itself on the lid of a large bucket and trace its outline. It is better to make markings with a felt-tip pen, as the mark is clearly visible.

It is important to note that all connections must be airtight; therefore, before installing the cover, the connection area must be coated with sealant. You also need to coat the junction of the wooden ring and the small bucket.

Installing the side pipe

The side pipe is made from a sewer outlet of 30 degrees (or 45 degrees). To install it, you need to drill a hole in the top of the small bucket with a crown. note that top part The bottom of the small bucket has now become its bottom.

Top entry installation

To make the upper input, you need to drill a hole in the upper part of the chip sucker (small bucket), that is, in the center of the former bottom.

To firmly fix the inlet pipe, use additional element strength in the form of a square piece of 20 mm thickness with a central hole for a 50 mm pipe.

This workpiece is fastened from below with four self-tapping screws. Before installation, the joint must be coated with sealant to ensure a tight seal.

Installing a shaped insert

The figured insert is very important component homemade chip blower, it must be secured inside the cyclone filter, as shown in the photo.

Cyclone filter assembly

Then you need to connect the air ducts correctly:

1. Upper pipe – to a household vacuum cleaner
2. An angled outlet that enters from the side at an angle to the hose.

The homemade cyclone vacuum cleaner (chip cleaner) is ready.

Video this review is based on:

About filters.
The cyclone filter does not retain more than 97% of dust. Therefore, additional filters are often added to them. “HEPA” is translated from English as “High Efficiency Particulate Air” - a filter for airborne particles.

Agree that even you cannot imagine your life without such necessary equipment like a vacuum cleaner? They cope not only with dust, but also with dirt.

Of course, vacuum cleaners can be used not only at home, but they also come in different types: battery-powered, washing, and pneumatic. As well as automobile, low-voltage industrial, backpack, gasoline, etc.

Operating principle of a cyclone vacuum cleaner

James Dyson is the first creator of the cyclone vacuum cleaner. His first creation was G-Force in 1986.

A little later in the 1990s, he submitted a request to manufacture cyclone devices and had already assembled his own center for the creation of vacuum cleaners. In 1993, his first vacuum cleaner, known as the Dayson DC01, went on sale.
So, how does this miracle work? cyclone type?

It appears that the creator, James Dyson, was a remarkable physicist. Thanks to centrifugal force, it is involved in collecting dust.

The device has two chambers and is divided into two types - external and internal. The air that spins inside the dust collector moves upward, as if in a spiral.

According to the law, large dust particles fall into the outer chamber, and everything else remains in the inner chamber. And the purified air leaves the dust collector through filters. This is how vacuum cleaners work cyclone filter.

Vacuum cleaners with a cyclone filter, features

Do not opt ​​for those models that require little power. You will definitely not like this kind of cleaning and most likely, you will want to throw away such a device.

Don't waste your money, but take a more serious approach to buying a vacuum cleaner. You just have to contact the sales consultant and he will help you with choosing a particular vacuum cleaner.

You should choose a device that is 20-30% more powerful than a bagged vacuum cleaner. It is best to take the one with a power of 1800 W. Almost all vacuum cleaner manufacturers produce models with this filter, which is good news.

Advantages of cyclone dust collectors

1. This has probably happened to everyone, when an item you accidentally needed ended up in the dust collector? Now this is not a problem because it is transparent! And you will always be able to notice objects that need to be pulled out of there as quickly as possible.

This is one of the most important advantages.

2. The power of such vacuum cleaners is maximum and does not reduce speed and power, even when the container is clogged. Cleaning is much more enjoyable, power does not drop, cleaning is cleaner.

This vacuum cleaner is capable of holding much more than you imagine. Up to 97%!!! Not likely, right? Although some are dissatisfied with this result, as they prefer vacuum cleaners with a water filter.

3. When buying a cyclone vacuum cleaner, you not only do bargain purchase, but also save space for storing it, since its weight is quite light. You won't have to carry heavy weights.

4. There is no need to constantly change paper bags for the vacuum cleaner.

5. Power. She is not lost from fullness.

6. It can be washed thoroughly with water and dried.

Disadvantages of cyclone dust collectors

1. One of the disadvantages of these vacuum cleaners is not very pleasant. This is washing and cleaning the filter. Of course, you won’t have to clean the container with a brush every day, but still, this is one of the disadvantages. Laziness is present in every person. Yes, of course it’s unpleasant to face the fact that you need to get your hands dirty.

2. Noise. There is much more noise from this type of vacuum cleaner than from a regular one.

3. Energy consumption. It is also much higher than that of a conventional vacuum cleaner. It's a small tornado.

Buy this small miracle or not, it's up to you to decide. In fact, all its advantages outweigh its few shortcomings. A clean house is much nicer than a half-finished tidy, wouldn’t you agree?

Personal impressions

Compared to an old vacuum cleaner, the cyclone dust collector looks quite modest in size. It is impossible to believe that such a little thing is capable of something serious. Now old vacuum cleaner Can only be used for wet cleaning.

When I use it for the first time, I take out the accessories, insert a small diameter pipe, turn on the device, and what’s really surprising is that the brush cleans the carpets much better than my previous assistant.

He cleans everything. Dirt, hair from our pets. Previously, you had to make a lot of effort to cope with such “now little things”.

I have laminated flooring in my hallway and it was just as easy to clean. The fact is that I have another brush in stock, tougher than the previous one for carpets, so I coped with this task so easily. You know, the sound of this vacuum cleaner is not as loud as they wrote about it on the Internet.

I am pleased with this device because it is light and not so loud. I also liked the compartment for storing all the necessary attachments; it is very convenient that it is built into the vacuum cleaner itself.

Once I knew what this little tornado could do, it was time to clean out the container. Thank God, when I started emptying the dust collector, it fell in dense, large clumps.

Since the debris was compacted by the air flow. There are no clouds of dust visible, and it did not rise into the air! So I finished my first cleaning with my cyclone vacuum cleaner. I rinsed the container and that was the end of the cleaning!

All vacuum cleaners are designed for one purpose - cleanliness. This applies to all vacuum cleaners.
Industrial and construction vacuum cleaners are usually used on machines or for cleaning any premises. These vacuum cleaners are quite expensive, since the operating principle of the cyclone filter vacuum cleaner must be selected carefully.
You should also know that industrial devices are most often used during repairs and construction. Leave yours workplace needs to be clean.

DIY cyclone, from transparent plastic video

Construction work is carried out after preparing it and cleaning the surface. As you understand, General cleaning impossible to do with a regular vacuum cleaner. In other words, this is fraught with damage to the device.
Even small debris such as sand, oil, dry mixtures, powder abrasives and wood shavings– Designed for industrial vacuum cleaner only.
If you suddenly go to choose a vacuum cleaner for construction work, then be sure to specify the types of pollution that it will encounter.
Are you planning to use a vacuum cleaner in a repair environment? Then consider the DIY cyclone vacuum cleaner option. There are many examples of how you can make this kind of vacuum cleaner.

DIY cyclone for vacuum cleaner

1. In order to make such a vacuum cleaner yourself, you will need a Ural PN-600 Vacuum Cleaner, a plastic bucket (even suitable for paint), a pipe 20 cm long and 4 cm in diameter.
2. The nameplate is also unscrewed, and the holes need to be sealed.
3. The pipe is quite thick and will not fit into the hole, so you need to grind off the rivets using a grinder and remove the pipe fastenings. Before doing this, remove the springs with clamps. Wrap electrical tape around the plug and insert it onto the plug.
4. At the bottom, make a hole in the middle with a drill. Then expand it to 43 mm with a special tool.
5. To seal it, cut out gaskets with a diameter of 4 mm.
6. Then you need to put everything together, the bucket lid, gasket, centering pipe.
7. Now we need self-tapping screws 10 mm long and 4.2 mm in diameter. You will need 20 self-tapping screws.
8. Cut a hole from the side of the bucket along the suction pipe. The cutout angle should be 10-15 degrees.
9. We try on and edit the shape of the hole using special scissors that cut for metal.
10. Don’t forget that you need to try on the inside too. Also leave strips on the inside for self-tapping screws.
11. Using a marker, mark the hole in the bucket and trim off the excess material with scissors. Attach the pipe to the outside of the bucket.
12. To seal everything you need to use a 30x bandage. From an ordinary first aid kit and glue like “titanium” for polystyrene foam. Wrap a bandage around the pipe and soak it with glue. Preferably more than once!
13. While the glue is drying, you can check how this vacuum cleaner will work. Turn on the vacuum cleaner and load it, blocking the nozzle with your palm. When checking the operation of the vacuum cleaner, the process of sealing and connection with the pipe is improved. It is unlikely that he will soon become obsolete.
14. It is best to store the vacuum cleaner in a case.

A home vacuum cleaner is so commonplace in the household that no one thinks about the principle of its operation. Since the invention of this cleaning assistant, it has been used only possible way separating dust from clean air– filter.

Over the years, the filter element has been improved, from a banal bag made of thick tarpaulin, it has turned into high-tech membranes that retain the smallest particles of debris. However, it was not possible to get rid of the main drawback.

Filter creators are constantly looking for a compromise between cell density and throughput for air. In addition, the dirtier the membrane, the worse the air flow through it.
30 years ago, physicist James Dyson made a breakthrough in dust collection technology.

He invented a compact dust separator that works on the principle centrifugal force. I must say that this idea was not new. Industrial sawmills have been using centrifugal cyclone-type scorch and chip storage for quite a long time.

But no one thought to use it physical phenomenon in everyday life. In 1986, he registered a patent for the first cyclonic vacuum cleaner, called G-Force.

In general, there are three ways to separate dust from clean air:

1. Filter membrane. The most widespread and cheap way remove dust. Used in most modern vacuum cleaners;
2. Water filter. Air with debris passes through a container of water (like in a hookah), all particles remain in a liquid medium, and a perfectly clean air flow comes out. Such devices have gained popularity, but their use has not become widespread due to their high cost.
3. Centrifugal dry cleaning filter of the “cyclone” type. It is a compromise in cost and quality of cleaning compared to a membrane and water filter. Let's look at this model in more detail.

Operating principle of a cyclone

The illustration shows the processes occurring in the chamber of a cyclone-type filter.

Contaminated air enters the filter housing (2) through the pipe (1) cylindrical. The pipe is located tangentially to the walls of the housing, due to which the air flow (3) twists into a spiral along the walls of the cylinder.

Under the influence of centrifugal force, dust particles (4) are pressed against the inner walls of the housing, and under the influence of gravity they settle into the dust collector (5). Air with the smallest particles of debris (which are not affected by centrifugal force) enters the chamber (6) with a conventional membrane filter. After final cleaning they exit into the receiving fan (7).

During renovation and construction work, a lot of debris appears. Sawdust, shavings, scraps of materials mixed with dust must be removed regularly. Regular sweeping with a mop is excluded due to the specifics of the work, if dust and small particles can stick to the surface, for example, after priming or painting.

An ordinary vacuum cleaner will not cope with such debris or will quickly break down. Household electrical appliances designed for medium short-term load.

For such cases, specialized equipment is produced. Construction vacuum cleaner can work for quite a long time without stopping, has significant power, and uses completely different household vacuum cleaners, filter systems.

When should you use a construction vacuum cleaner?

Those who are constantly faced with construction, repair and carpentry work know about the need to timely clean the workplace at the end of the stage. Cleaning can be done multiple times in one day, so it’s reasonable to want to make the process easier for yourself.

Pieces of foam and polyethylene film , scraps of gypsum board, chipped plaster, dust from cutting aerated concrete - all this debris settles not only on horizontal surfaces, but is also electrified and attached to vertical walls.

Cleaning with a mop and dustpan is not always appropriate due to large areas, and washing will only turn dry dirt into wet slurry, especially in unfinished rooms.

Due to the small size of the dust container, a regular household appliance will quickly become clogged and will have to be continuously cleaned. If large particles get in, there is a high risk of breaking the equipment.

It is in such conditions the best solution will use a construction vacuum cleaner.

Pros and cons of a construction vacuum cleaner

Greater power allows professional equipment work without interruption for a long time, and the long hose provides access to remote areas without the need to carry the vacuum cleaner or interrupt work.

But it also has disadvantages:

• High cost. If periodic or one-time work is necessary, purchasing a new expensive tool is not practical.
• Large sizes and weight.

Some craftsmen have come up with a way out in the form additional option to existing technology. At fairly low costs, you can assemble a cyclone filter for a vacuum cleaner with your own hands. This design will increase the capabilities of an existing conventional household vacuum cleaner.

Making a cyclone with your own hands

On the Internet there is huge selection instructions for self-production cyclone filter, including attached drawings and photographs. But they are united by a standard set of components.

So, what do we need:

Assembly instructions.

The main indicator that a cyclone for a vacuum cleaner is assembled correctly with your own hands will be debris collecting at the bottom or settling on the walls of the container, while the suction will be fast and high-quality. Do not forget to check the tightness of the structure.

The history of the cyclone filter

The creator of cyclone filter technology is James Dyson. It was he who first made a filter with operation based on the action of centrifugal force. Why did this device become so popular and in demand that the inventor filed a patent for it?

The filter consists of two chambers. Under the influence of centrifugal force inside the unit, the debris begins to swirl into the funnel. Large trash at the same time, it settles in the first chamber, the outer one, and dust and light debris collects on inside. This way, clean air comes out through the top hole.

The main advantages of the cyclone filter:

• no need for dust collection bags and their constant replacement;
• compact filter sizes;
• quiet operation;
• An easy-to-remove lid allows you to regularly check the level of contamination and promptly dispose of garbage;
• speed and efficiency of work.

A vacuum cleaner with a cyclone filter can be used both at home and for professional purposes.

Recently I became interested in working with wood and the issue of removing shavings and sawdust arose very urgently. So far, the issue of cleaning the workplace has been solved with a home vacuum cleaner, but it quickly becomes clogged and stops suction. You have to shake out the bag often. In search of a solution to the problem, I looked through many pages on the Internet and found something. As it turns out, it is possible to make fully functional dust collectors from scrap materials.

Mini vacuum cleaner made from a plastic bottle

Here is another idea for a mini vacuum cleaner based on the Venturi effect
This vacuum cleaner operates using forced air.

Venturi effect

The Venturi effect is a pressure drop when a liquid or gas flows through a constricted portion of a pipe. This effect is named after the Italian physicist Giovanni Venturi (1746–1822).

Rationale

The Venturi effect is a consequence of Bernoulli's law, which corresponds to the Bernoulli equation, which determines the relationship between speed v liquid, pressure p in it and height h, on which the fluid element in question is located, above the reference level:

where is the density of the liquid, and is the acceleration of gravity.

If the Bernoulli equation is written for two sections of the flow, then we will have:

For a horizontal flow, the average terms on the left and right sides of the equation are equal to each other, and therefore cancel, and the equality takes the form:

that is, with a steady horizontal flow of an ideal incompressible fluid in each of its sections, the sum of the piezometric and dynamic pressures will be constant. To fulfill this condition in those places of the flow where average speed fluid is higher (that is, in narrow sections), its dynamic pressure increases, and the hydrostatic pressure decreases (and therefore the pressure decreases).

Application
The Venturi effect is observed or used in the following objects:

• in hydraulic jet pumps, in particular in tankers for oil and chemical products;
• in burners that mix air and combustible gases in the grill, gas stove, Bunsen burner and airbrushes;
• in Venturi tubes - constricting elements of Venturi flow meters;
• in Venturi flow meters;
• in ejector-type water aspirators, which create small vacuums using the kinetic energy of tap water;
• sprayers (sprayers) for spraying paint, water or aromatizing the air.
• carburetors, where the Venturi effect is used to draw gasoline into the inlet air stream of an internal combustion engine;
• in automated swimming pool cleaners, which use water pressure to collect sediment and debris;
• in oxygen masks for oxygen therapy, etc.

Now let's look at the samples that can take their rightful place in the workshop.

Ideally, I would like to get something similar to a cyclone filter, but from scrap materials:

Homemade chip separator.

The principle is the same, but made much simpler:

But I liked this option the most, since it is a smaller analogue industrial cyclone:

ch1

Since I don’t have a traffic cone, I decided to settle on this design, assembled from plastic pipes for sewerage. An undoubted advantage is the availability and low cost of material for assembling the structure:

Homemade cyclone from plastic sewer pipes

Please pay attention to the mistake that the master made. The garbage collection pipe should be located like this:

In this case, the desired vortex will be created.
The following video shows a similar design in action:

And finally, a slightly modified version:
