Abstract

A forced circulation and fast flotation separation device and method is suitable for flotation of easily floating coarse particle minerals or coal. The device comprises a transmission mechanism, a flotation tank body, a fast flotation system and a forced circulation system. An inverted trapezoid platform is arranged below the flotation tank body, a foam tank is arranged at the top of the invertedtrapezoid platform, a concentrate discharging pipe is arranged at the lowest position of the foam tank, a sieve plate is arranged at the foam tank in the cylinder, the forced circulation system is arranged in the inverted trapezoid platform of the flotation tank body, a plurality of guide plates are arranged between the forced circulation system and the sieve plate, the transmission mechanism is arranged at the top of the flotation tank body, and the forced circulation system comprises an upper guide cylinder, a propelling wheel, a dispersing stator, a centrifugal mineralizing wheel and a lower guide device arranged below the centrifugal mineralizing wheel and fixed at the bottom of the tank body. The device is simple in structure and high in separation efficiency.

Description

technical field [0001] The invention relates to a separation device and method, especially a forced circulation fast flotation separation device and method suitable for the flotation separation of easy-to-float coarse particle minerals or coal. Background technique [0002] At present, the equipment used for mineral flotation separation mainly includes two types of equipment: flotation machine and flotation column. Among them, the flotation machine is considered to be relatively suitable for the flotation of coarse-grained minerals, and is widely used in industrial practice. According to the working principle, it can be mainly divided into mechanical stirring flotation machine and air flotation machine. The self-aspiration mechanical agitation flotation machine uses the rotation of the impeller or rotor to inflate and agitate the pulp; the inflatable agitation flotation machine is a flotation machine that combines mechanical agitation with external air pressure. Compressed...
