Description

(54) SPRAY COLOR CAMERA

one

The invention relates to the equipment of paint shops, specifically to spraying devices for coating, and can be used in enterprises producing mass coloring products.

A known aisle spraying chamber, comprising a housing, a hydraulic filter, a vertical water screen, and a sedimentary bath with lattice screen filters, located under the chamber.

The disadvantage of such a spraying chamber is that the particles of the sprayed paint, which are in the water, settle to the bottom of the sedimentary bath and to the filter screen and contaminate them. This requires periodic manual cleaning of both the sediment bath itself and the strainers. The sedimentary bath is located under the painting chamber, as a result of which access to it is difficult.

Also known is a spray booth containing sprayers, vertical and inclined screens, a hydraulic filter, an inclined tray and a sedimentary bath with a cumulative capacity of 2. In this device, the sedimentary bath is located not under the painting booth, but at the side of it.

The last device is closest to that described.

The disadvantages of this device are the imperfect process of trapping paint from water, the need for periodic manual cleaning of a sedimentary bath, and the presence of a lifting mechanism for removing the storage tank from the ground.

The purpose of the invention is to reduce the labor intensity and enable the mechanization of the process of separation and

5 disposal of waste paint from water.

To achieve this goal, a spray painting chamber containing sprayers, vertical and inclined screens, a hydraulic filter, an inclined tray and a sedimentary tank with a cumulative capacity, is equipped with a mesh drive drum mounted on a horizontal shaft in the sediment bath and partially immersed in it, the discharge tray, installed in the mesh drum in its upper part, and placed above the waste tray on the outside of the drum

air collector, and the storage tank is located under the waste tray.

Such a design eliminates the possibility of the deposition of paint waste on the bottom and walls of the sedimentary bath, its accumulation, clogging of the pumps, and ensures effective removal of paint from water. ;

The drawing schematically shows the device, a general view.

Spray painting chamber 1 contains sprayers 2, vertical screen 3, inclined screen 4j hydro filter 5, tilt tray b and sedimentary bath 7, The device is equipped with a mesh drum 8 mounted on a horizontal shaft rotatably driven by actuator 9 and partially loaded into sedimentary bath 7. Inside the mesh drum 8 in its upper part is mounted a waste tray 10, above which an air collector 11 is placed on the outside of the drum 8,

Under the discharge tray 10 outside the drum, a storage tank 12 is installed for collecting paint waste.

A pump 13 is provided for returning the purified water from the sediment bath 7 to the vertical screen 3 and the hydraulic filter 5.

The device works as follows.

When the paint is supplied to the spray gun 2 and water to the vertical screen 3 and the hydraulic filter 5, the products in the chamber are painted.

Water flowing down the vertical screen 3 and the inclined screen 4, as well as from the hydraulic filter 5, captures the excess not settled on. the product of paint and carries it along the inclined tray 6 into the inner cavity of the mesh drum 8. Under the action of flow and gravitational forces, polluted, the water passes through the grid of bariban, is cleared of paint and enters the sediment bath 7, from where the pump 13 is fed into the vertical screen 3 and the hydraulic filter 5, From the drive 9 of the mesh

bar.abai 8 gets a constant rotation with a small number of revolutions. As it rotates, the mesh, contaminated with paint waste, falls into the area of action of a jet of compressed air supplied from the air manifold 11 to the outside of the mesh drum B, and is cleaned. Paint deposits and water droplets removed from the inner surface of the grid with a jet of compressed air using the discharge tray 10 are collected in a storage tank 12 mounted on the floor. After the storage tank is filled, the collected paint waste is fed to the regeneration.

The described device completely eliminates the use of manual labor for cleaning the sedimentary bath and significantly reduces the cost of this process.
