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

Abstract

The invention belongs to the technical field of coal slime flotation machines, and particularly relates to a flotation machine with high bubble surface flux and a particle bubble mineralization device. The particle bubble mineralization device comprises a mineralization device shell, a jet aerator and a slurry-gas mixer; the jet aerator and the slurry-gas mixer are arranged in the mineralization device shell, and the slurry-gas mixer comprises guide blades and protruding rods; the bubble mineralization efficiency of the particle bubble mineralization device is improved by arranging the slurry-gas mixer; the flotation machine comprises a separation barrel, a lower barrel body and a tailing chamber; a fluidization water chamber is arranged at the upper end of the separation barrel, the particle bubble mineralization device is arranged on the outer side of the separation barrel, and an inclined plate is arranged on the lower barrel body, so that the flotation machine can work under the conditions of high bubble surface flux and washing water flux, and no free foam layer flotation is achieved; an inclined plate channel is adopted at the lower end of the flotation machine to strengthen separation of mineralized bubbles and ore pulp, it is ensured that a foam area is maintained in a vertical area on the upper portion of the equipment, the lowest ore pulp amount is carried, and the separation effect is improved.

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...
