Description

C 5) yCTPOJ CTBO FOR PAINTING PRODUCTS

one

The invention relates to painting equipment and can be used in paint shops of engineering plants.

A device for painting products is known, comprising a hydrofilter with an air-flushing channel, a receiving circuit, a water bath and exhaust ventilation system 1.

The disadvantage of this device fg is that the air is sucked through the whole volume of the chamber, as a result of which a considerable consumption of air, electricity and water is required to clean the aspirated air from the chamber.

Closest to the proposed device for painting products, containing a hydraulic filter with an air washing channel, a flooring, a receiving circuit, 20 telescopic walls forming an air vent, a water bath, an exhaust ventilation system, and a fluid supply pump 2.

However, in the known device, telescopic walls operate in the zone of polluted air and therefore are quickly clogged with paint. The paint also settles on the moving walls and the mechanism of their movement, which reduces the reliability of the installation and worsens the conditions of its operation.

The aim of the invention is to improve the quality of cleaning and improve operating conditions.

Claims (2)

This goal is achieved by the fact that in a device for painting products containing a hydraulic filter with an air-cleaning channel, flooring, receiving circuit, telescopic; the walls forming the exhaust duct, the water bath, the exhaust ventilation system and the fluid pump; the receiving circuit is reversed by transverse partitions installed under the flooring. Between the receiving circuit and the air exhaust duct, a tray is installed for maintaining the water curtain, and the heating walls are made in the form of pipes with openings in the lower part connected to the pump for supplying fluid to the walls to form water screens. FIG. 1 shows a schematic view of the device; on. performance of telescopic walls; in fig. 3 - section A-A of FIG. 2; 4, iyaen 1 of FIG. 2. A device for painting products I includes gratings 1 for installing the surroundings of the product being injected and a hydraulic filter 2 for cleaning contaminated air. The receiving circuit 3 in the painting area is formed by transverse partitions A and is connected to the hydraulic filter 2 by the air vent 5. The telescopic walls 6, forming the air vent 5, are made in the form of tubes 7 and 8, on which sheets 9 and 10 are attached. The flooring 1 has a bath (in Fig. 1 it is conventionally not shown) for liquid 11 (Fig. 2). A filter 12 and a pump 13 are used to collect liquid from the bath. Between the receiving circuit and the air outlet channel, a tray 13 is installed to form a water curtain 15. Through pipes 16, 17 and 18, the liquid enters the hydraulic filter 2, pipe 8.7 and tray II The pipes 7 are connected to the pipe 17 through the flexible elements 19. The telescopic walls are fixed in the supports 20 and 21. The hole 22 serves to supply fluid to the pipe 7. The dimensions of the sheets 9 and 10 are chosen so that they are immersed in the liquid 11 by the bottom edge. cleaning when mkov and telescopic removable shields 23 are provided. Tray 14 is fixed on supports under removable cyte 23. It is closed from above, with a flexible lid 2. Inside the tray, with the possibility of moving along it, there are installed small pipes 25, which support pipes 8 and are connected to them. through cable 26 and axis 27. Tg 26 is connected to sheet 10 and through axis 28 to the mechanism for moving walls 6. (not shown in drawing.) In pipes 7 and 8, holes 29 are punched out. Water flowing out of the holes forms water screens 30 on sheets 9 and 10. The device operates as follows. When the product is painted, the polluted air enters one of the receiving circuits 3, passes through the water curtain 15, is pre-cleaned and enters the air separation channel 5, formed by telescopic walls 6. Due to the presence of water screens 30, the paint particles do not settle on sheets 9, 10 The air flow, when interacting with the water screens, is additionally cleaned and then gets into the air inlet, first hydraulic filter channel 2. When the painting zone changes, the movement mechanism is turned on, the roller 25 moves inside the tray I, the wall 6 occupies wrap the new position, connect the air vent to the new receiving circuit 3.. This device will allow stepwise suction of air directly from the paint area, improve the quality of air cleaning, reduce the pollution of the telescopic walls, and improve the equipment operating conditions. An apparatus for painting products, comprising a hydraulic filter with an air-washing channel, a flooring, a receiving circuit, telescopic walls forming an air-exhaust channel, a bath, -dl water, a exhaust ventilation system and a pump for supplying liquid, characterized in that In order to improve the quality of cleaning and improve the operating conditions, the receiving circuit is formed by transverse partitions installed under the flooring, with a channel between the receiving circuit and the AIR CONDUCTING channel. A second curtain, the telescopic walls being made in the form of pipes connected to a pump for supplying fluid with openings in the lower part, on which sheets are fixed to form water screens, i.
