A high bubble surface flux flotation machine and particle bubble mineralizer

Abstract

The invention belongs to the technical field of coal slime flotation machines, and specifically relates to a high-bubble surface flux flotation machine and a particle bubble mineralizer. A jet aerator and a slurry gas mixer, the slurry gas mixer includes guide vanes and protruding rods, the bubble mineralization efficiency of the particle bubble mineralizer is improved by setting the slurry gas mixer, the flotation machine includes a sorting bucket, The lower barrel and the tailings chamber, the upper end of the sorting barrel is provided with a fluidized water chamber, the outer side is provided with a particle bubble mineralizer, and an inclined plate is arranged on the lower barrel, then the present invention can achieve high air bubble surface flux and washing water flux Working under the same conditions to achieve flotation without free foam layer, the lower end of the flotation machine adopts inclined plate channel to strengthen the segregation of mineralized air bubbles and pulp, ensuring that the foam area is maintained in the vertical area of ​​the upper part of the equipment, and carries the lowest amount of pulp, which improves the separation Choose an effect.

Description

technical field [0001] The invention belongs to the technical field of coal slime flotation machines, in particular to a high-bubble surface flux flotation machine and a particle bubble mineralizer. Background technique [0002] Froth flotation is a general method for selecting minerals from fine-grained ore pulp. The flotation machines that use foam flotation include mechanical agitation flotation machines, jet flotation machines and flotation columns. Whether it is mechanical agitation flotation Both the machine and the flotation column equipment have the following common problems that affect the further improvement of the separation efficiency: [0003] First, the rising and falling pulp flows of the mineralized bubbles are coupled and interfere with each other. Due to the turbulence of the pulp flow, the mineralized bubbles are broken, and the target minerals fall off from the mineralized bubbles. The non-target mineral fine mud enters the foam layer, causing the pollut...

Problems solved by technology

However, when the diameter of the jet bubble generator is large, a liquid jet core will be formed in the center of the jet beam, which affects the dispersion and mixing efficiency of the inhaled air and the jet fluid, and affects the mineralization effect of the particle bubbles.

The Chinese patent "A Mixed Flow Microbubble Generator and Bubble Distributor" (Application No. 201821730868.7) has a spiral blade in the output pipe, and the Chinese patent "Self-priming Microbubble Generator" (utility model CN95239169.4) is in the output pipe Setting static stirring blades, the above solutions are all helpful to solve the above problems, but the problem is that the particle bubbles move in the same direction in the narrow channel in the built-in component, the gas-liquid mixing intensity is low, and the particle bubble collision mineralization efficiency needs to be further improved
