(54) PURPOSE PULSE COLORING CAMERA

The invention relates to spray coating devices and can be used in paint and primer lines. A known painting chamber containing a hydraulic filter with semi-cylinders forming an air flushing channel, a vertical water screen and a sedimentary bath 1. However, due to the location of the sedimentary bath under the hydraulic filter, the collection of paint deposits is difficult. Closest to the proposed invention, a pass-through spray painting chamber containing a frame, a hydraulic filter with half-cylinders forming an air-flushing channel, a vertical water screen and an inclined water screen located in the lower part of the chamber and connected by an inclined tray with a sedimentary bath in which boxes are installed to collect of paint deposition 2. The disadvantages of this chamber are the low degree of purification of air polluted by spray paint, the rapid clogging of paint of cleaning elements (for example, unok, separators, blowers, nasoevyh installations, pipelines) for cleaning are required bolschoy labor and energy costs. In addition, difficult working conditions for installation and disassembly of the elements of the air cleaning channel of the hydraulic filter. The purpose of the invention is to improve the quality of purification of polluted air and improve working conditions during maintenance. This is achieved by having a hydraulic filter with half-cylinders forming an air-flushing channel, a vertical water screen and an inclined water screen located in the lower part of the chamber and connected with an inclined tray with a sediment bath in which the drawers are installed. collection of paint deposits, the half-cylinders of the air washer channel are installed with the possibility of rotation in a vertical plane by means of fixed on the inner surface of the hydraulic filter housing Guides with brackets, with the guides made of rolled steel, brackets fixed to the outer surface of the semicylinders and equipped with an adjusting screw, and on the side walls of the hydraulic filter there are openings with doors installed in them, in addition, the boxes are equipped with handles that exceed the water level in bath, sedimentary bath is equipped with a filter with a cap installed in its upper part, and the surface of the vertical screen is punched out perforated.

FIG. 1 schematically shows the proposed camera, a general view; in fig. 2 is given a cross section A-A in FIG. one; in fig. 3 - raarez bb in fig. one; in fig. 4 depicts a hydraulic filter, side view; in fig. 5. A section bb of FIG. one; in fig. 6 is a section d-d in FIG. four; in fig. 7 shows the node I in FIG. 6; in fig. 8 - node And in FIG. four.

The cramer consists of a metal frame 1, a perforated vertical water screen 2, the internal cavity of which is connected to the air washer channel 3 of the cascade hydro filter 4. The air washer channel 3 is formed by one-piece semi-cylinders 5 which are fixed inside the hydro filter filter body 6 with adjustable brackets 7. Guides 6 made of a corner and rigidly fixed on the inner surface of the housing of the hydraulic filter, and brackets are rigidly attached to the outer surface of the semicylinders 5, with At the upper row brackets, protrusions 8 are made with holes, threaded and adjusting screws 9. A bath-tray 10 is located above the semicylinders, and in the upper part of the air-lavage channel 3 there are drainage plates 11. On the lateral sides of the hydraulic filter 4 there are openings equipped with hermetic glazed doors 12.

In the chamber zero, an inclined water screen 13 is formed, which is the bottom of the chamber and connected by inclined trays 14 to the sedimentary bath 15, which is taken out of the chamber in the water. Inside, the bath is equipped with a filter 16 and a filter 17 with a plug in the upper part, which serves to trap the upper layer of water contaminated with small fractions, which is collected by the overflow pocket 18 and two outlets 19 and 20 connected respectively to the circulating pump 21 and the brightening chamber (drawing not shown). In addition, the sedimentary bath is equipped with an automatic fresh water supply device 22, which is a widely known float valve consisting of a body, a chopper, a lever, a stop needle (piston), a fork and a saddle. Boxes 23 are installed at the bottom of the sediment bath 15, which serve to collect paint deposits and have handles 24 protruding above the water level in the bath, which allows replacing them

without stopping the camera. The bath 15 and the inclined tray 14 are covered with lids 25 and 26, and the inclined screen 13 is blocked by the floor 27. Water from the bath 15 through the pipeline 28 is supplied to the pocket 29, and through the pipeline 30 to the bath tray 10, the product 31 is painted from the atomizer 32.

The camera works as follows.

Circulating pump 21 water from

sediment van 15 through filters 16 and 17

but line 28 is fed into pocket 29

the vertical screen 2 and, overflowing, forms a water screen, and through the pipeline 30 water is supplied to the bath-tray 10 and through its sides evenly flows along the inner surfaces of the half-cylinders 5, forming a cascade of water curtains.

When the semi-cylinder is skewed, on which the bath-tray 10 is located, the adjustment of the angle of inclination of the semi-cylinder in the vertical plane of the hydraulic filter is carried out by screwing in the adjusting screw 9 into the ledge 8 of the bracket 7 (and if necessary by unscrewing the screw). The screw, resting its lower part on the flange of the guide 6, aligns the skewed side of the half cylinder. Having achieved a uniform flow of the water film along the entire length of the half-cylinder, the adjustment of the angle of inclination of the half-cylinder stops.

Saving the product 31 from the spray gun 32, part of the paint flying past

product, it hits the perforated vertical water screen 2 and is caught by the streams of falling water, with which it then falls on the inclined water screen 13. And the air polluted with a spray paint through the holes of the perforated vertical screen 2 is uniformly sucked from the entire chamber area into the air wash channel 3 of hydraulic filter 4. Passage of a cascade of water curtains; air is mixed with water, finally

it is cleared of spray mist and, striking the drainage plates 11, is dehydrated, and then is thrown out of the workshop.

The water contaminated with paint is transported on the moon water screen 13 and the inclined tray 14 flows into the sedimentary bath 15. The paint is deposited in the crates 23, which, as they accumulate, are removed from the bath and released.

The sedimentary bath is regularly replenished with portions of fresh water through the device 22, and the upper layer of water contaminated with light fractions is retained from entering the circulating pump 21 by the filter plug 17 and collected in the overflow pocket 18, from which through outlet 20 is removed into the chamber clarification.

The proposed camera will improve the quality of cleaning the air polluted by the spray paint by adjusting the film thickness of the water curtain along its entire length, reducing labor costs and time during installation, dismantling, cleaning of the elements of the hydraulic washer and the sediment bath.
