Slurry mixing and stirring tank for fine-grain mineral flotation

Abstract

The invention discloses a slurry mixing and stirring tank for fine-grain mineral flotation. The slurry mixing and stirring tank comprises a stirring tank body (1), baffle plates (2), a frequency adjusting motor (4) and a stirring shaft (5); the baffle plates are uniformly distributed on the inner wall of the stirring tank body; the frequency adjusting motor is mounted at the top of the stirring tank body; an output shaft of the frequency adjusting motor is connected with the stirring shaft; a mixing impeller (6) is mounted at the bottom end of the stirring shaft; a feed pipe (11) is arranged on the lower side wall of one side of the stirring tank body; an overflow pipe (12) is arranged on the upper side wall of the other side of the stirring tank body; one ends, near the stirring shaft, of the baffle plates are cylindrical; the other ends, near the side walls of the stirring tank body, of the baffle plates are straight plate-shaped; rectangular gaps are formed in the straight plates of the baffle plates; and a plurality of turbine generators (3) are uniformly distributed between the stirring shaft and the baffle plates. The slurry mixing and stirring tank intensifies the effects of the baffle plates by improving accessories of the baffle plates, and the turbine generators are used to generate streamwise vortexes by using a flow pattern in the stirring tank, so that the reinforcement of shearing strength in the stirring tank and the enhancement of the turbulent effect are achieved, and the high-efficiency mineralization is realized.

Description

technical field [0001] The invention relates to a slurry mixing tank, in particular to a slurry mixing tank used for flotation of fine minerals, and belongs to the technical field of mineral processing equipment. Background technique [0002] The slurry mixing tank is one of the important auxiliary equipment in the flotation process. It plays an important role in the mixing operation of ore pulp and chemicals. The slurry mixing tank mainly realizes the mixing and mixing of materials and chemicals by means of mechanical stirring. , so as to ensure the stirring and contact time between the agent and the mineral, and realize the full dispersion of the mineral and the complete reaction of the agent. The ore often needs to be finely ground before flotation, and can only enter the flotation equipment after being ground to a certain size, so as to improve the flotation index. However, fine-grained minerals tend to aggregate in the stirring tank to form small-scale particle cluster...

AI Technical Summary

Problems solved by technology

Traditional slurry mixing tanks use standard straight baffles to restrain tangential movement in the mixing tank, but this structure of mixing tanks is not effective for mixing fine-grained minerals. Problems such as time lag and low separation recovery rate, poor mineralization effect
