    55 11, combined with module 2
    and fitted with vertical filters. 12, which can be of any type, however, the use of filter elements made, for example, of folded paper folds over a cylinder having a metal frame, makes it possible to reduce the volume of sections 10 and P. Sections 10 and II can contain a different number of filter elements. The number of filter elements is determined by the conditions of use of filters and the cross section of products 4, mounted on suspension frames 13, made in the form of plates that help seal the upper part of module 2 during the spraying of the coating on the product. In general, the case of section 10 and P must be equipped with the same filters in the same quantities. Sections 10 and 11 are connected by a box 14 with one fan 15, the intake pipe of which is located below the filters 12. The box 14 contains a fiyestr regeneration system, for example, a blockage block filtering unit (not shown). In another embodiment, box 14 may also include a fan. The input compartment 6 of module 1, as well as the output compartment 7 of module 3 contain two vertical filters 16 and one horizontal filter 17, made in the form of plates and forming partitions of mezvdu inlet 18 and output 19 holes of the compartments and ducts 20 and 21, ensuring the return of air in the cycle. Partitions 22 of filtering departments: modules 1 and 3 form a corridor. 23, which allows the separation streams containing the powder exiting module 2 to be separated from the return air after filtration, in sections 10 and 11. In module 3, an air dryer 24 is installed. The filter compartments 8 and 9 are equipped with devices 25, fluidizing the filtered powder and feeding it into the container 26 for accumulation and recuperation of the powder through the sieve unit 27. The container 26 is bounded by walls 28 and is equipped with a powder level sensor 29. Module 2 is equipped with powder distributors 30 connected to a compressed gas line (not shown) and fixed in the upper part of walls 28 of tank 26. Powder atomizers 30 are connected to removable powder intakes 31 and mounted on pipes 32, 74.: immersed in a container 25 to accumulate and recover the powder. The pipes 32 are adjustable in height by means of a screw 33 relative to the holder 34, moving in the pipes 35. The powder sprays 30 are provided with caps 36 preventing the powder from settling on the guns and are connected by cable 37 to a high voltage source. The screening device 27 comprises a crush 38 fixed to the frame 39, connected to a vibrator 40 and supplied with precipitators 41 metal particles fixed to the frame 39 and made in the form of flexible magnetic elements 42, which are in the form of a tape or plates mounted on rigid bases. Module 2 is also equipped with a powder reflector 43, made of two U-shaped elements mounted in the upper part of module 2 and attached to the module's head with bolts 44. At the same time, part of the reflector can be made with double walls 45 and 46 installed with by inclination to the plane of movement of the articles and ensuring the flow of the powder. In another embodiment, the powder reflector is made in the form of curved plates 47 and attached with bolts 48 to the collar of module 2. In addition, module 2 is also provided with a removable shield 49 located on the side wall of the module and allowing access to powder powders 30. All three modules 1, 2 and 3 are provided with angles 50 located in the upper parts of the modules and forming between them a gap 51 for the passage of the hanging frames with the products and strengthening the construction of the modules. Modules 1 and 3 are equipped with U-shaped frames 52, which form hollow elements that facilitate air circulation. The ends 53 of the corner 50 at the entrance to the module 1 and at the exit from the module 3 are spread out to guide the suspension frames 13 into the entrance gap, between corners. Fixing the corners on the lid of the module 2 allows building in a series of different installation modules. The placement of the corners is such that the mini- mum distance between them can be equal to the thickness of the plate of the suspension frame at the level of its width;
    through the gap between the corners, which reduces the likelihood of powder ejection through this gap.
    The installation may contain several modules 2, allowing the paint to be coated with various colors. The modules are fastened to each other by means of fastening tapes. . ,
    The materials used to make the installation depend on the type chosen for applying the powder; The spray chamber must be made of a material with a high dielectric strength, for example polypropylene, to prevent current leakage.
    The installation works as follows.
    The product 4, the underlying coating, is fixed on the suspension frame 13 and with the help of the conveyor 5 through the product entry hole enters the module
    1 and then into the spray unit 2, where with the help of the spreaders 30, the charged powder is sprayed and deposited on the product. Spray guns that spray the powder are poured simultaneously or separately, depending on the desired coating. The powder level sensor 29 controls the introduction of a new batch of powder. In the module
    2, the required amount of powder is stored. This stock may consist of two parts, one of which contains recovered powder, and the other fresh powder.
    The screening device 27 processes the powder obtained by regenerating the filters 12 or not deposited on the product. Small metal filings are captured by magnetic elements 42.
    The powder in the spray gun is supplied by intakes 31 and pipes 32, which are immersed in the stock of powder in the container 26. Such transportation of the powder allows you to avoid the use of external elements and eliminates cumbersome pipelines. The removable shield 49 allows access to the interior of the pad module without the need for personnel to enter. chamber volume
    The stock of powder can be easily replaced for use with powders with other characteristics.
    The presence in the module 2 of the powder reflector of two parts, for example, of a material that converges, makes it possible to seal the sputtering module in the region of the gap through which the suspension frames with the product pass. Moreover, this gap, formed by the corners 50, can be equal to the thickness of the suspension frame at the level of its passage between the corners, which significantly reduces the likelihood of powder drift through the roof of the chamber.
    The reflector protects from a down; No attachment of the suspension frames avoids drying the product on the product, which would lead to a violation of the quality of the coating.
    The air circulation created by the fans in the inlet and outlet modules causes a pressure drop in module 2 and an increase in pressure in the inlet and outlet ports of modules 1 and 3. Under these conditions, the powder cannot go beyond the installation.
    The air from the sputtering chamber enters the filter compartments 8 and 9. There is no air coming in from outside, therefore there is no air preparation problem, there is no penetration problem from the workshop. The 1st air returns to the cycle again. The filters 16 and 17 prevent the powder from being carried to the surrounding atmosphere in the event of the destruction of the filters 12.
    In the event of an emergency, the differential pressure gauge will shut off the air intake.
    The filters 16 are under high voltage, which reduces the settling of the powder by. wall filters. The coated product is withdrawn from the installation through module 3 and is applied for heat treatment.
    . The modular installation device allows to increase its mobility and replacement of elements. Modules can be quickly assembled with fasteners. Tape, providing tightness and quick disassembly. 0 - ..,.
