Abstract
The invention belongs to the technical field of coal slurry conditioning and flotation and particularly relates to quantitative chemical adding, reverse stirring and center slurry conditioning integrated flotation equipment. The equipment at least comprises a flotation tank, stirring mechanisms and a quantitative chemical adding system. The stirring mechanisms are horizontally arranged in the flotation tank in a paired mode. Each rotary drum is provided with a forward rotating blade and a reverse rotating blade which are formed by welding blades. Dispersion holes in the surfaces of the blades and gaps between the blades can cut and disperse ore slurry and air. The forward rotating blades and the reverse rotating blades drive the ore slurry towards each other, and thus the mineralization effect of the ore slurry is enhanced. The ore slurry and chemicals can be sprayed out together through second discharging ports and third discharging ports in stirring sleeves, and the mineralization degree is further improved. A quantitative chemical adding system on a feeding pipe can add chemicals into the feeding pipe intelligently according to the real-time ore slurry flow, and the chemical dosage is reduced. The equipment further comprises a circulating foam scraping mechanism, and full tank surface foam scraping is achieved. The quantitative chemical adding, reverse stirring and center slurry conditioning integrated flotation equipment has the advantage that ore slurry preprocessing equipment is not needed.
