Description

covered neck 7, tank 4 is constantly in communication with the atmosphere.

The tank 5 is connected via a valve 8 with a tank for the material 2 and is equipped with sensors of the upper 9 n lower 10 levels and a three-way valve 11 on the compressed gas supply magnet 12, which communicates the atmosphere 5 in one of the positions.

All cranes are remotely controlled. Capacities 4 and 5 are significantly less than capacity 2.

The installation works as follows.

Through the neck 7 with the cranes 6 and 8 open, a certain amount of enamel shlykera is poured into the container 2. In this case, tanks 2 and 5 through the taps 3 and 11, respectively, communicated with the atmosphere.

When the unit is turned on, the valve 8 is closed and compressed air is supplied through the valve 3 into the container 2. The slip is squeezed into the pipeline, passes through the sprayer 1 in the closed nozzle, and is discharged into the container 4, and then through the valve 6 into the container 5.

When the upper level sensor is activated, the valve 6 is closed and the valve 8 is opened. Compressed air is supplied to the lower container 5 through the valve 11 and the slip flows into the container 2. When the lower level sensor 10 is triggered, the valve 8 is closed, the container 5 is connected with the atmosphere by means of the crane 11 . The valve 6 is opened, and the click of the upper tank 4 flows into the lower tank 5. The cycle is repeated, thereby providing

constant circulation of the clicker. When opening the spray nozzle 1, the coating is applied to the product.
