An integrated flotation equipment for quantitative dosing, reverse stirring, central slurry adjustment

Abstract

The invention belongs to the technical field of flotation for slurry adjustment of coal slime, and in particular relates to an integrated flotation device for quantitative dosing, reverse stirring and central slurry adjustment. The present invention at least includes a flotation cell, a stirring mechanism and a quantitative dosing system; the stirring mechanism is horizontally arranged in pairs in the flotation cell, and the rotating cylinder has a forward-rotating impeller and a reverse-rotating impeller welded by the impeller, and the dispersion of the impeller surface The gap between the hole and the impeller can cut and disperse the pulp and the air flow; the forward-rotating impeller and the counter-rotating impeller respectively drive the pulp to the other side, which intensifies the mineralization effect of the pulp; the second discharge on the stirring sleeve The mouth and the third outlet can spray out the slurry and the chemical agent together, which intensifies the degree of mineralization again. The quantitative dosing system on the feeding pipe can intelligently add the chemical agent to the feeding pipe according to the real-time pulp flow, saving The amount of medicine used; the equipment also includes a circulating foam scraping mechanism to realize foam scraping on the entire groove surface; the present invention has the advantage of not requiring pulp pretreatment equipment.

Description

technical field [0001] The invention belongs to the technical field of flotation for slurry adjustment of coal slime, and in particular relates to an integrated flotation device for quantitative dosing, reverse stirring and central slurry adjustment. Background technique [0002] With the shortage of coal resources in my country and the improvement of coal mining mechanization, the deterioration of coal geological conditions has led to a decrease in the grade of raw coal mined from underground mines. At present, most coal preparation plants adopt dense medium cyclone production process, which increases the amount of secondary slime produced in the washing process and increases the burden on the later stage of slime water treatment; in addition, the current Chinese coal market continues to decline, Under the increasingly difficult situation of on-site production environment, in order to change this status quo, try new technology and speed up the research and development of ne...

Problems solved by technology

From the existing flotation equipment, mechanical agitation and jet flotation machines are used in most coal preparation plants, but both require pulp pretreatment devices and have their own advantages and disadvantages
