Description

Efficient intelligent phosphorite flotation tank Technical Field The utility model relates to the technical field of ore dressing equipment, in particular to a high-efficiency intelligent phosphorite flotation tank. Background The phosphorite flotation technology is to separate, enrich and refine by utilizing the difference of interface properties of phosphorite, a flotation tank is an important key device in the phosphorite flotation technology, and the working principle is that the phosphorite is mixed with a medicament to form ore pulp, then the ore pulp is injected into the flotation tank, the ore pulp is stirred by a stirrer, air is injected into the ore pulp through an air distributor to form bubbles, hydrophobic mineral particles are attached to the bubbles to rise, finally the ore pulp floats to form foam, the foam is scraped and collected by a scraper, and non-hydrophilic mineral particles are settled in the ore pulp. The existing air distributor is single in pore diameter of an aeration hole, formed bubbles are often insufficient, minerals needing to be floated cannot be effectively captured, the floatation effect is affected, the fact that the foam layer of a floatation tank is not timely changed is found, the scraping plate is difficult to scrape foam, or too much foam is not timely scraped, the floatation effect is deteriorated, the floatation effect is affected, the foam scraped by the scraping plate cannot be timely destroyed in grooves on two sides in the floatation process, the tank is easily spilled, and the mineral loss and the environment pollution are caused.
