Abstract

Usage: the invention relates to mechanical engineering and can be used in the application of coatings on large-sized products to reduce operating costs and reduce overall dimensions. SUMMARY OF THE INVENTION: The cross section of the drying chamber is smaller in area than the adjacent cross section of the spray booth. The transverse wall of the spray booth, adjacent to the dryer, is covered by a U-shaped stationary wall and swing gates placed in the opening between the chambers. The side opening of the spray booth is covered by a longitudinal wall mounted for movement in the direction of the drying chamber and provided with a supporting roller for engaging with a guide attached to the area for the heat ventilation units. At the same time, a platform for heat ventilation units is placed above the drying chamber. 3 ill.

WITH

The invention relates to mechanical engineering can be used in the application of paints and varnishes. coatings for bulky products.

The aim of the invention is to reduce operating costs, downsizing.

Figure 1 shows a painting and drying complex, side view; in Fig.2 is a section aa in Fig.1, Fig. 3-section bB in Fig.1.

The device comprises a housing 1 of a drying chamber with wings 2 swing gates. A platform 3 is located above the chamber body for accommodating and servicing the heat ventilation units (not shown) of the drying chamber. The platform 3 rests on the posts 4 and is provided with a guard made on the side of the gate 2 in the form of a continuous sheet 5.

The device also contains a floor grate 6 located in the spray booth, a collection bath 7 for circulating water, an overflow bath 8 and a tray 9 located under the grate. Hydraulic filters 10 with an overflow bath 11, half cylinders 12 and baffle plates 13 are placed on the rear longitudinal side of the floor grate. The gaps between the protection filters are by the sheets 14. A stationary wall 15 is placed at the right end of the grating, which is joined to the sheet 14 of the rear longitudinal wall. The leaves of the swinging doors of the drying chamber are placed on the left end of the floor grill, and the space on the side and

hell with the camera body is sewn up with a continuous P-sheet 16. From the near longitudinal side of the grating 6, the complex is equipped with a flat movable wall 17, which is supported by the drive 19 through the wheels 18 and moved by the drive 20. A roller 1 is installed in the upper part of the wall 17, which enclosed in a guide 22 welded to the drying kiln site 3. A stop 23 is attached to the end wall 15 to fix the closed position of the movable wall 17.

The product 24 is placed on a trolley 25, which is supported through the running wheels 26 on a rail track 27 and is moved by a cable drive 28.

Painting and drying complex works as follows. Starting position: trolley 25 is located on floor grate 6, gate 2 of the drying chamber is closed, movable wall 17 is in the closed (right) position.

The actuator 20 is turned on and the sliding wall 17 is moved to the leftmost position. The product 24 is installed by the workshop crane on the trolley 25. The drive 20 is turned on and the wall 17 moves to the extreme right position, isolating the product from the workshop room.

Pumps (not shown) are turned on, which feed the zod from bath 7 to overflow baths 8 and 11. Fans (not shown) are also turned on, which are connected to the upper flanges of the hydrofilters 10 and sucked air out of the bath tub 7. In this case, the air from the workshop moves from top to bottom in the space bounded by the walls 14,15,16,17 and through the floor grate 6 it enters the hydraulic filters 10. Passing through the water curtains formed by the water flowing from the tray 9 of the overflow baths 8 and 11, the polluted air is cleaned of paints and varnishes is drained by fenders shields 13 and is removed to the atmosphere. Through doors (not shown), the sprayer enters the floor grill and paints the product.

At the end of the painting, the gates 2 are opened and the carriage 25 together with the product moves inside the housing 1, the drying chamber, after which the gates 2 are closed. The pumps and fans of the floor grille are turned off and the fan heaters (not shown) are turned on, which supply the circulating heated air to the inside of the casing 1 of the drying chamber. The product is dried.

At the end of drying, the fan heaters are switched off, the doors 2 of the drying chamber open, and the trolley 25 s

dried product 24 is rolled out onto floor grate 6.

The gate 2 closes, the drive 20 is turned on, and the wall 17 moves to the extreme

left position, after which the product 24 is removed by the workshop crane from the cart 25. Then, the cycle can be repeated.

In the claimed device, the floor grate adjoins directly to the drying chamber, and the sliding wall in the open position is placed within the length of the drying chamber, which allows reducing the workshop area required for the complex to be installed.

5 Fencing of the .kras zone by -. simple means: stationary walls 15, 16 and the housing of the drying chamber, as well as a sliding wall 17, which requires little power to move it, increases the reliability and safety of work.

Reliable, due to the simplicity of the means, isolation of the paint zone allows to reduce the amount of suction fans

5 through air hydrofilters, improve the working conditions in the workshop.

The complex does not require deep marks, which reduces the cost of construction, manufacturing and operation, and also reduces the dimensions of the device.

Claims (1)

SUMMARY OF THE INVENTION A paint-drying complex comprising a paint and adjacent drying chamber with an opening between them for 5 passage of products, heat ventilation units located on the site, the spray booth is made with an opening in the side wall for passage of products and is equipped with an air purification system, floor 0 grid and a bath placed under the floor grill, characterized in that, in order to reduce operating costs, reduce overall dimensions, the cross section of the drying chamber is smaller 5 areas of the cross section of the spray booth adjacent to it, the transverse wall of the spray booth, adjacent to the drying chamber, is blocked by a U-shaped stationary wall and swing gates placed in the opening between the chambers, and the side opening of the spray booth is blocked by a longitudinal wall mounted for movement in the direction drying chamber and provided with a supporting roller for interacting with a guide attached to the site for the heat ventilation units, while the site for heat ventilation units placed above the drying chamber.
