    A spray booth installation has a water tank 10 from which water is withdrawn by a pump 11 to feed a water curtain covering a wall located above a dividing baffle plate 17 in the tank and to feed sprays in an air extraction passage disposed above a region 16 of the tank. A surface- removal device 20 including a venturi pump keeps the water surface clear of paint in the vicinity of the pump inlet 13 and ejects the floating paint on the other side of the baffle plate 17. A surface baffle 30 retains floating material while allowing water to circulate underneath it and back to the front region 15. <IMAGE>

    (5) SPRAY PAINTING DEVICE
    one
    This invention relates to a spray painting technique.
    A device for spray painting is known. its end wall, the unit for removing paint from the surface of the water with the inlet and. outlet nozzles located in different sections of the tank, and a hydraulic filter with a water-cooled screen and nozzles 3
    However, in a known device in the area of the suction nozzle there is a floating paint, which can lead to blockage of the pump.
    The aim of the invention is to increase the reliability of operation.
    This goal is achieved by the fact that in a spray painting device comprising a water tank divided into two interconnected sections by a longitudinal baffle mounted with a gap relative to one
    10 of the end walls of the tank and protruding above the water level in it, the pump, the suction nozzle of which is introduced into the cavity of the tank through its other end wall, block
    15 to remove paint from the surface of the water with inlet and outlet nozzles located in different sections of the tank, and a hydraulic filter with a water tap screen and nozzles,.

    The 20 inlet of the unit is located at the suction inlet of the pump, with a transverse surface partition between the longitudinal partition and the side wall of the tank in one of the sections with a clearance from 25 to the bottom. The outlet of the unit is located in a section of a tank with a transverse surface partition. The hydrofilter is installed above the section of the tank with a transverse surface partition, with the water-overflow screen of the hydrofilter located above the continuous partition. The water tank is provided with an additional surface septum, which is a continuation of the longitudinal septum to the end wall. The suction port of the pump is located in the section with a transverse surface partition. The device can be equipped with an additional unit for removing paint from the surface of the water, with the main and additional units mounted on opposite sides of the transverse surface partition. The water tank is equipped with additional partitions, one of which is installed parallel to the main one and connected to its free end by means of another additional reflecting partition. In this case, the hydraulic filter is installed above the section of the tank sections, oi the limited main and additional baffles, with the water overflow screen located above the additional baffle parallel to the main one. FIG. 1 shows schematically the proposed device, a general view; in fig. 2 is a section A-A in FIG. 3 section bb in FIG. in fig. - another device variant (water tank with additional baffles); in fig. 5 section bb In figure 4; in fig. 6 is a vertical section of GG in FIG. k ,. The device comprises a rectangular-shaped water tank 1, divided by a longitudinal baffle plate 2 into two sections 3 and communicating with each other. A longitudinal reflective partition is installed with a gap relative to the wall 5 of the tank 1 above the level of water in it. In addition, the device contains a pump 6, the suction nozzle 7 of which is inserted into the section 3 of the reservoir 1 through the end wall 8, and a unit for removing paint from the surface of the water, the Venturi unit (not 8 4 reading input 9 and output 10 nozzles. Input nozzle The unit 9 is located at the suction inlet 7 of the pump 6. The pump 6 supplies the flushing fluid through the screen filter 11. In the tank section C, a transverse surface partition 12 is installed with a clearance relative to the bottom 12 t A hydraulic filter 13 is installed above the tank section A with a water tap screen ohm 1. located above the longitudinal baffle plate 2 by the chute 15 into which water is supplied from the nozzle 16. An exhaust fan 17 is installed in the upper part of the hydraulic filter. Furthermore, the hydraulic filter has nozzles 18 for additional air flushing and inclined reflective plates 19 In the water tank 1, an additional surface partition 20 can be installed, which is a continuation of the longitudinal partition to the end wall 5 The device works as follows. When painting the product, the sprayed paint that has not fallen on it is either washed off with a water curtain of the water pouring screen I) or removed with the air flow and then washed out of the air flow and falls into section k of the tank. As a result, paint accumulates in the water in the tank, a part of which floats on the surface, the unit removes the floating paint in the immediate vicinity of the suction port 7 of pump 6, which reduces the risk of the pump suction nozzle and the pump itself being blocked with paint. The block also dispels the ink; as a result, heavier paint particles are deposited on the bottom of the tank, thereby reducing the volume of foam floating on the surface of the water. Circulation of water in the tank occurs from the outlet nozzle 10 of the block along section 4 of the tank to its end wall 5 and further through the gap between the end wall 5 and the longitudinal reflective partition 2 along section 3 to the block to remove paint from the surface of the water and to the end wall 8. A transverse surface septum 12 prevents participation in said circulation of floating paint. Thus, the paint that stopped floating after exiting the unit is assembled in section 4 of the tank between the transverse surface partition 12 and the end wall 8. Due to the presence of the partition 12, water circulates under the partition 12. The additional surface partition 20 is a continuation of the partition 2, therefore, the portion of section k limited by the end wall 5 and the partition 12 can be used to trap the floating paint. The floating paint particles that fall into the zone between the end wall 8 and the n partition wall 12 are exposed to several forces. The block causes a lot of movement and turbulence in this zone and can disperse a continuous stream of air bubbles that keep paint particles afloat. At the same time, strong transverse currents are formed on the surface of the water, resulting from the air and water cascade removed from the paint product zone from the flood shield 1 and nozzles 18. This mixing promotes the crushing of the paint, which prevents clogging of the pump 6. After the final separation Floating paint particles solids settle to the bottom of the tank. Paint particles or other floating particles that were not ground with the described mixing can be removed from the WATER surface as needed. In the embodiment of the device shown in FIG. 4-b, the tank 1 is also divided by a longitudinal reflective partition 2 into two sections 3 and 4. However, in this case, the partition 2 is part of the vertical wall 2 of the hydraulic filter located along the water inlet screen 1, the hydraulic filter also has nozzles 18 and inclined reflective plates 19- In the tank, additional reflective partitions 22, 23- are installed. Partition 22 is parallel to partition 2 and connected to it by partition 23- Partition 22 is installed with a relative gap On the end wall 8 of the tank, and between the partition 23 and the end wall 5 there is a passage connecting between the top section 3 and the tank. The suction nozzle 7 of the pump is inserted into the 0 "section k of the tank. The unit is also located in section k, and its outlet 10 is led out to section 3. As a result, water is circulated in the opposite direction to that which occurred in the device shown in Figures 1-3. In this case, the transverse surface partition 12 limits the access of floating paint to the block. In the section between the end wall 5 and the transverse surface septum 12 an additional unit is placed to remove paint from the surface of the water with an inlet 2k and outlet 25 nozzles. The outlet 25 passes through the baffle 2 into the section 3 section bounded by partitions 2, 22 and 23. In this area the paint is mixed by the action of the water curtain of the tap-in screen 14 and the water jets supplied by the nozzles 18. In this device the reservoir is located a zone for coloring products, however it is possible to install it separately from the painting zone; In this case, the water containing the paint is directed to the reservoir along the gutter. The proposed device is reliable in operation and does not require expensive filtering equipment. 1.
