Description

(54) BATH COLOR CAMERA HYDROFILTER

I

The invention relates to spraying devices for products and can be used in paint shops of machine-building enterprises.

The famous panna hydro4 paint booths, including a series of settling bridges, a strainer, suction overflow drain and feed pipe O.

However, this bath is characterized by a low degree of purification of circulating water.

Closest to the invention is a bath of a hydraulic filter of an oiipasic chamber containing a strainer and a nozzle for draining clarified water 2.

A disadvantage of the known bath is the lack of means registering the degree of contamination of the filter; with strong contamination the filter screens break through, especially in the area. suction pump, which reduces the cleaning efficiency of circulating water.j

The purpose of the invention is to improve the quality of cleaning circulating water from paint.

The goal is achieved by the fact that in the bath of the hydro filter of the spray booth containing a strainer and a nozzle for clarification of clarified: water, the strainer is equipped

10 installed in its upper part of the ballast chamber with a visor, open at the bottom, a movable labyrinth seal in the lower part and a signaling device connected to the visor,

The tS filter is installed with the possibility of vertical movement in guides that are mounted in the bath.

Claims (2)

FIG. 1 shows schematically a bath; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1. 3 Hydrofilter bath contains strainer 1, mounted with the possibility of vertical movement in gazih directions mounted in a bath (not shown), a ballast chamber located in its upper part, open to the bottom consisting of float chamber 2 ii communicating with it an air chamber 3. A float chamber 2 is equipped with a fitting 4 for supplying or venting air and a visor 5 connected to a signaling device 6. A movable labyrinth seal is installed in the lower part of the mesh filter 1, including a partition 7 and movable and arched partition 8. The device operates as follows. When the screen filter 1 is soiled, its mass increases and the float chamber 2 is flooded. At the same time, the visor 5 connected to the alarm device 6 is also immersed, the contact of the alarm device actuates, a sound or light signal is issued to replace the screen filter 1. In addition, the visor 5 is selected so that when the float chamber 2 is completely sunk, the visor 5 remains the water level in the bath, dividing the water mirror into two parts, and does not allow the paint particles floating on the water surface to penetrate into the pump suction zone, the screen filter mine. By the position of the visor 5 above the water level, I can also visual to monitor the degree of dirtiness strainer 1. Using the present invention will improve the quality of cleaning of the circulating water and, thereby, increase the technical terms IU ode obslz stallation chamber. According to preliminary calculations, the economic effect from the use of this device will be 4 thousand rubles. per one spray booth. Claims of the Hydrofilter Bath of the painting chamber containing a strainer and a nozzle for draining clarified water, characterized in that, in order to improve the quality of circulating water purification from paint, the strainer is equipped with a ballast chamber installed in its upper part open from the bottom, movable a labyrinth seal in the lower part and a signaling device connected to the visor, while the strainer is mounted with the possibility of vertical movement in guides which are mounted in the bath. .
