The invention relates to wastewater treatment, allows purification from extraneous liquids, solutions and mixtures of impurities removed in the foam, and is applicable in the food industry.

The purpose of the invention is to increase the efficiency of collecting foam from the surface of the fluid being cleaned.

The drawing shows the proposed device, a general view.

The device contains a ballast chamber i with an air supply pipe 2 and a collector 3 installed above the ballast chamber, connected to the pump suction inlet, made in the form of an inverted funnel and provided with an irrigation collector 4 at the base.

The ballast chamber 1 is connected via pipe 5 to a water system 6 and pipe 7 to a system 8 of compressed air. The device also contains valves 9-15 and pipeline 15.

The device works as follows.

For thorough separation, the stuffed-water mixture and the fat-containing foam, a vacuum suction method is used, for which a foam collecting device is placed in a container with the stuffed-water mixture. Using the ballast (water) filling of the ballast chamber 1, the clearance C1 is adjusted between the surface of the stuffing mixture and the edge of the funnel 3, i.e. the suction effect of the device is regulated. This is done as follows. In order to reduce the clearance.

minced-water mixture and intensifies the leaching of fats from minced meat and the formation of fish stump on the surface :. One time, water is supplied from the irrigation collector 4 to quench the foam. Then a vacuum is created under the OT, vacuum is sucked in through the slit formed by the OT base and the ballast chamber 1. 1 sludge.

those. the foam collection device is tapped and the suction effect is increased; the valve 9 is closed automatically on the water system 6 and the valves 10 and 11 are opened.

In the air system 8, the valves 12 and 13 are closed and the valve 14 is opened. Water flows through the pipeline 5 into the ballast chamber 1, the air is forced out through the pipeline 7 and the valve 14 into the atmosphere. Upon reaching the required clearance q (determined practically depending on the amount of foam and density of the stuffed-water mixture), the valves 10 and 14 are closed. If the device for collecting foam is too tight and the gap is small and the suction effect is too strong, it is necessary to carry out the ascent of the device, i.e. to increase the gap q, for which it is necessary to reduce the volume of ballast (water) in the ballast chamber I. At the command, valves 9 and 10 automatically open and valve 1 on the water system 6 closes, valve 13 opens and valves 12 and 14 on the air system close . As a result, air from the air system 8 through the pipeline 7 enters the cavity of the ballast chamber 1, displaces water through pipeline 5, valves 10 and 9 and irrigation collector 4 to the outside, thus the mass of the device decreases, it pops up, and the gap increases .

After setting the gap a to the required size, the valves 9-14 are closed. For collecting the foam, a funnel 3 through conduit 16, valve 15, and bend313

These hoses (not shown) are connected to a vacuum system.

Before collecting the foam in the pipeline 2. Compressed air is supplied through pipeline 8, opening the valve 12 with a closed valve 13. The air coming from pipeline 2 additionally mixes the stuffed-water mixture intensifies the leaching of fats from the meat and the formation of fat on the surface foam. At the same time, water is supplied from the irrigation collector 4 with the valves 9 and 11 open and the valve 10 closed, thereby achieving some damping of the foam and washing it from large particles of minced meat, i.e. holding the stuffing in the water and preventing it from catching with foam. Then the valve 15 is opened and a vacuum is created under the funnel 3, the foam is sucked in vacuum through the gap b between the funnel 3 and the ballast chamber 1.

Since the whole device of foam collecting is connected to stationary systems for supplying water, compressed air and vacuum with flexible hose pipes (not yet
