DEVICE FOR FLOTATION SEPARATION OF NANO- AND MICROSTRUCTURES MIXTURE Russian patent published in 2017 - IPC B03D1/24 B03D1/02 

FIELD: nanotechnology.

SUBSTANCE: device for the flotation separation of nano- and microstructures mixture contains a cone-shaped body, an annular inclined groove for collecting the foam product, a branch outlet for the chamber product in the cone lower part, and aerators with pulp and air feed nozzles. The cone-shaped body is divided by height-adjustable cylindrical partitions, the symmetry axes of which coincide with the axis of symmetry of the cone-shaped body. At least the outer cylindrical partition is set in height above the edge of drain threshold. Aerators with pulp and air feed nozzles are installed in the body evenly along the circumference of its surface. As aerators, sound pneumohydraulic and/or jet aerators are used. The nozzles of the sound pneumohydraulic and/or jet aerators are directed down along the surface of the body cone and at an acute angle to the generatric of body cone.

EFFECT: increase the degree of separation of nano- and microparticles with simultaneous reduction of energy costs.
