SELF-REGULATING FLOTATION PLANT Russian patent published in 2021 - IPC B01D21/00 B03D1/14 B03D1/02 C02F1/24 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, instrumentation, construction industry and is intended for the purification of industrial and domestic wastewater from pollutants. The self-regulating flotation unit contains a housing with pipes for supplying contaminated water, removing purified water, a flotation device, a foam removal device with a rotation drive and an annular foam collector. Inside the body of the flotation plant there is a tank 3 with external floats 5, in which there is a spiral belt conveyor 12 mounted on a shaft 4 with a rotation drive. The foam removal device in the form of a cup in the form of a truncated cone 11 with helical blades 9 is installed with a smaller base in the center of the spiral belt conveyor 12. The blades 17 are mounted on the shaft 4, and a flotation device 18 is installed in the lower part of the tank. There are holes 16 on the side walls of the tank 3, in front of which there are inclined reflective screens 2 inside the tank 3. The central shaft 4 with a rotation drive in the upper part has a slot connection and is designed to move freely up and down the central opening of the flotation device 18 in the lower part of the tank 3. The foam removal device in the form of a cup represented by a truncated cone 11 in the upper part has a movable contact with the upper edge of the internal floating tank 3 in the form of a drain visor directed into the annular foam collector 10.

EFFECT: invention provides an improvement in the quality of water purification.
