TRANSFER DEVICE OF FROTH PRODUCT OF FLOTATION STAGE Russian patent published in 2015 - IPC B03D1/02 B03D1/08 

FIELD: mining.

SUBSTANCE: transfer device of froth product of a flotation stage includes a sump and a pump; the sump is equipped with connection pipes for introduction of froth product and for connection to the pump. The sump is made in the form of a conical reservoir with radial plate-type meshed baffle plates and with tangential supply of froth product and discharge of pulp to the pump. Its lower base represents a bottom of the conical reservoir. A flattened cone installed with its smaller base in an upward direction is located in the centre of the reservoir bottom. The lower side of the plate-like meshed baffle plate is located on the level of the upper base of the flattened cone. A froth product supply connection pipe is installed in the side wall of the reservoir at the height from the bottom of 0.1÷0.7H, where H - sump height, and the pump connection pipe is located in the lower part of the conical reservoir in the pulp flow direction, below the upper base of the flattened cone. The inner diameter of the pump connection pipe is equal to inner diameter of the froth product inlet connection pipe. Diameter of the lower base of the flattened cone is 0.3÷0.5 of diameter of the smaller base of the conical reservoir.

EFFECT: improving efficiency, work output of a device for transfer of froth product of a flotation stage and reducing energy consumption.
