Embodiment Construction

[0025] Such as figure 1 , 2 , 3, the flotation machine involved in the present invention generally includes a tank body for providing an ore slurry reaction space, and a hollow shaft 30 is movably installed in the tank body, and the stirring structure involved in this embodiment generally includes A stator unit 10 and a rotor unit 20 for stirring the ore slurry.

[0026] The stator unit 10 is fixed in the tank and forms an independent space to facilitate the cooperation with the rotor unit 20 to form a better stirring effect on the ore slurry. The stator unit 10 establishes a fence-like annular space. The ore slurry can be exchanged with the ore slurry outside the annulus under agitation by the rotor unit 20 .

[0027] The rotor unit 20 is installed in the annular space of the stator unit 10, and comprises a fixed frame 21 fixed on the hollow shaft 30, and blades 23 uniformly fixed on the circumference of the fixed frame 21. The blade 23 includes a connecting plate 231, and ...

Abstract

The invention provides a stirring structure of a flotation machine. The stirring structure comprises a stator unit and a rotor unit, wherein the stator unit is fixed in a groove body of the flotation machine; an annular space with interval clearances is formed around a hollow shaft in the groove body; the rotor unit is mounted in the annular space of the stator unit; the rotor unit comprises a fixed rack fixed to the hollow shaft and blades uniformly fixed to the circumference of the fixed rack; and the blades comprise connecting plates, and upper plates and lower plates which vertically extend in the opposite directions from the two ends of the connecting plates. In the stirring structure, an impeller forms a structure of which the circumference gradually expands from the bottom to the upper part, space distribution of air entering the rotor unit and the stator unit is reasonable, air is uniformly dispersed, a lot of small bubbles are generated through the rotor unit, and ore pulp mixing and air dispersion parameters are determined through the stator unit.

Description

technical field [0001] The invention relates to the field of ore sorting, in particular to a stirring structure of a flotation machine capable of improving stirring efficiency. Background technique [0002] The flotation machine mainly uses the difference in the physical and chemical properties of the mineral surface to make one or a group of minerals in the ore selectively attach to the air bubbles and rise to the ore liquid level, thereby separating the useful minerals from the gangue minerals. [0003] The general working method of the flotation machine is to make the ore slurry in the tank suck from the bottom of the tank to between the blades of the rotor through the rotation of the rotor. At the same time, the low-pressure air fed by the blower also enters it through the hollow shaft and the air distributor of the rotor. After the pulp and air are fully mixed between the blades, they are pushed out from the upper part of the rotor, and then the liquid mixed with air bu...
