Active air inlet device of flotation machine

Abstract

The invention discloses an active air inlet device of a flotation machine. The active air inlet device of the flotation machine comprises a flotation tank body, a partition plate is installed in the flotation tank body and divides the flotation tank body into two flotation areas, an air guide pipe is arranged in each flotation area, a main shaft is rotatably installed in each air guide pipe, the lower end of the main shaft stretches to be below the air guide pipe and is provided with a stirring assembly, one side of the air guide pipe is communicated with an air inlet pipe, air guide blades are arranged on the main shaft in the air guide pipe, a driving device capable of driving the two main shafts to rotate at the same time are arranged on the flotation tank body. The air guide blades are arranged on the main shaft, and can actively drain air in the air guide pipe downwards while rotating and working through the main shaft, and then through double inflation of the air inlet pipe and the air guide blades, the energy consumption is low, and the inflation amount can be increased; in addition, through the arrangement of the driving device, the two main shafts can be driven to rotate at the same time, a single motor does not need to drive a single main shaft, and therefore energy consumption is reduced to the minimum.

Description

technical field [0001] The invention relates to the field of flotation machines, in particular to an active air intake device for a flotation machine. Background technique [0002] Flotation machine is an important equipment to realize mineral flotation enrichment and separation. The technical and economic indicators of flotation are closely related to the flotation equipment used. There are many types of known flotation equipment, which are mainly divided into mechanical agitation flotation machines, inflatable agitation flotation machines, and inflatable flotation machines. For mechanical agitation flotation machines, the introduction of air is realized by the negative pressure generated by the high-speed rotation of the agitation impeller. When the agitation intensity is low, the generated vacuum is low, the amount of air introduced is insufficient, the flotation recovery rate is not high, and the agitation intensity is low. When it is high, the mechanical wear is serio...

AI Technical Summary

Problems solved by technology

For the mechanical stirring flotation machine, the introduction of air is realized by the negative pressure generated by the high-speed rotation of the stirring impeller. When it is high, the mechanical wear is serious and the energy consumption is high. Moreover, the stirring device is driven and rotated by a single motor, so the energy consumption is also high
