Feeding device of inflatable flotation column

Abstract

The invention relates to a feeding device of an inflatable flotation column, belongs to the field of flotation separation equipment and is particularly applicable to clean flotation and refinement of particles in fine flake graphite production. The feeding device of the inflatable floatation column consists of an upper column body, a feed chute, a diverting chute, an outer chute, an inner chute and sieve plates. The feed chute is arranged on the outer side of the upper column body, two ends of the diverting chute are respectively connected with the feed chute and the outer chute, the outer chute is arranged on the outer side of the upper column body, and the inner chute and the sieve plates are arranged on the inner side of the upper column body. The outer chute is a circular groove which is arranged, along the angle of alpha, on the outer side of the position at 1 / 2 height of the upper column body. The inner chute is a circular groove which is arranged, along the angle of alpha, on the inner side of the position at 1 / 2 height of the upper column body. The feeding device has the advantages that good crude mineralization effect, feeding stability and uniform feed distribution and good flotation effect are achieved.

Description

Technical field [0001] The invention relates to a feeding device of an inflatable flotation column, which is especially suitable for fine flotation and purification of fine-grained materials in the production of fine flake graphite, and belongs to the field of flotation equipment. Background technique [0002] The inflatable flotation column is widely used in fine flotation and purification of fine-grained materials in the production of copper, tungsten, molybdenum and other non-ferrous metals to improve the grade and recovery rate of non-ferrous metal flotation concentrates. The feeding device of the inflatable flotation column adopts The multi-point conical slurry feeding device has the following disadvantages: 1) The mineralization effect of the raw ore and the chemical agent is poor; 2) The feeding is unstable, and the feeding kinetic energy is large, the disorder is serious, and some air bubbles are easy to burst; 3) The feeding distribution Uneven, poor flotation effec...
