SU682281A2 - Apparatus for overflowing liquid from a tank - Google Patents

Description

a coarse tromo 14 and a BbinOviHen with an exit section for connecting the spray gun 15 to it with a compressed air supply system. On the output section of the bypass line filter 16 is installed fine. All equipment is mounted on a trolley, and a place for fixing them during transportation is provided for the nozzle 1 and the overflow device 2.

The device works as follows.

Shipping containers 17 (barrel, flashes, etc.) with the chosen color of paintwork material are installed near the product to be painted. A carriage with a device is supplied to the container 17, the pipe 2 with the nozzle 1 is lowered into the container up to the bottom of the container. The switching valves 6 and 7 are set to the "mixing" position, i.e., the closed recirculation (fng. 1).

When the pump 3 is turned on, the process of mixing the contents of the container 17 in a closed system begins:

the gap between the pipe 2 and the suction nozzle 1, flexible hose 4, switching valve 6, pump 3, circulation circuit 5, valve 7, flexible hose 4, pipe 2 and nozzles 9. At the exit of the nozzle 9 a stream of paint and varnish material is created pump 3, blurs at the bottom of the container 17 sediment. During the circulation process, with the valve 11 open, the solvent is captured from the tank 10, which, mixing with the paintwork material, creates a solution of the necessary viscosity.

Control of the viscosity of the paint-and-lacquer material solution is made by taking a sample from the crane 8.

In the same order, the paint and varnish material is unloaded from the shipping container through the crane 8 when using the proposed unloading device.

When the paints and varnishes material is ready for spraying, the switching valves 6 and 7 are turned to the "painting" position (Fig. 2).

In this position, while the pump 3 is running, the prepared paintwork material from the transport container 17 is sucked by the nozzle 9 into the pipe 2 and through the flexible hose 4 switching the valve 7, the pipe 18 of the circulation circuit 5, the pump 3 and the bypass pipeline 12 with a section of reduced section 13, through the switching valve 6 and the flexible hose 4 into the gap between the pipe 2 and the suction pipe 1 in the shipping container 17.

Section 13 of the reduced cross-section of the bypass pipeline 12 creates the necessary

the pressure of the paintwork material in the bypass pipe and at its outlet to the spray gun 15.

Before applying the paintwork material, it is filtered from coarse impurities.

When compressed air is supplied and the spray gun 15 is put into operation, the prepared solution goes through the fine filter 16 to its nozzle and is applied to the product in the form of a torch, but the bulk of the solution enters the transport container for mixing.

The presence of a solvent tank makes it possible to use a shipping container as a container for a paintwork material solution of a desired viscosity, and a bypass line with a reduced section to create the necessary pressure before entering the spray gun and to return the solution to the shipping container during periods when the paint nozzle closes.

Thus, the proposed device can be widely used in industrial plants, in construction, in field conditions, in repair shops and especially in enterprises and in organizations where there are no paint preparation areas and spraying installations.

The use of the proposed device will make it possible to exclude from the process of preparing a solution of paintwork material for dispersing such equipment as:

a device for the overflow of paintwork material from the transport container into the container;

container with a device for mixing;

means for transporting the paintwork solution to the product to be painted.
