SU844077A1 - Chamber for painting articles by spraying - Google Patents

Description

The invention relates to techniques for painting, in particular, for cleaning air from an aerosol of paint using the Venturi principle, which ensures efficient capture of its particles by spraying water and agglomeration of the aerosol of paint in the venturi.

Known chamber for spray painting, containing a supply duct installed in its upper part, grating, drainage panels, bath, settling tank, water deflectors, suction system and water line [1].

The disadvantages of this chamber are the bulkiness of the bath with a large volume of water, which is not involved in the process of air purification and is the accumulator of the deposited paint particles, and the difficult access to the bath during its cleaning.

The purpose of the invention is to improve serviceability.

To achieve this, in the chamber for spray-painting products containing a supply duct installed in its upper part, grating, drainage panels, bathtub, settling tank, water deflectors, suction system and water main, the bathtub is designed as a ^ -shaped tray mounted under drainage boards on racks installed with optional 2.

nosty of vertical movement in the air-tunnel made with the hatch, with which the camera is equipped.

The drawing shows the proposed 5 camera, section.

The chamber 1 for spray painting includes a supply duct 2 installed in its upper part, a grating 3, under which drainage 10 shields 4 and a water main 5 are mounted for supplying water to them.

The camera 1 is equipped with a bathtub made in the form of an lV-shaped tray 6 mounted under the shields 4 on the racks 7 mounted15 with the possibility of vertical movement. Tray 6 is mounted in an air tunnel 8 with a hatch 9. Between the edges of the shields 4 and the surface of the water in the tray 6 there is a gap that serves as a slot 10 20 Venturi.

The chamber 1 also includes a settling tank I, visors 12 mounted in the tunnel 8 on the shields 4, water deflectors 13, and a suction system with an exhaust fan (not shown) that is installed after them along the air flow.

Camera for painting works as follows.

During painting of the product 14, air is supplied through the robot 2 with the specified parameters of 844077 temperature and humidity. An exhaust fan creates an air flow that captures paint particles that have not settled on the surface of the painted product 14, and in the form of an aerosol through the floor 3 enters the gap 10. When crossing the latter, an air stream saturated with paint particles crosses the water curtain, mixes with water and high speed through the slot 10 turbulently enters the tunnel 8.

Water coming from line 5 contains a coagulant. The particles of paint treated by it settle to the bottom of tunnel 8 and are discharged into the tank 11 by a stream of water, and the air released from the paint in a turbulent stream in tunnel 8, when passing in the area of water deflectors 13, is freed from moisture and is released into the atmosphere. The size of the slit 10 is regulated by changing the height of the struts 7. When cleaning the tunnel 8 use the hatch 9.

The proposed camera is reliable and easy to use.

Claims (1)

Claim A spray booth containing a supply duct installed in its upper part, a grating, drainage panels, a bathtub, a settling tank, water deflectors, a suction system and a water main, characterized in that, in order to improve serviceability, the bathtub is designed as lV-shaped tray mounted under drainage boards on racks installed with the possibility of vertical movement in a water-air tunnel made with a hatch, with which the camera is equipped.
