Description

Technical Field

[0001] The invention relates to the technical field of flotation machine separation, in particular to a flotation machine separation mechanism for zinc oxide slag treatment. Background Art

[0002] In the flotation machine, the pulp treated with reagents is added, and through stirring and aeration, some of the mineral particles are selectively fixed on the bubbles and scraped out with the foam, while the rest are retained in the pulp, achieving the purpose of separating minerals. At present, the most commonly used is the stirring flotation machine. When treating zinc oxide slag, the servo motor drives the impeller to rotate, generating a centrifugal effect to form a negative pressure. On the one hand, sufficient air is inhaled to mix with the zinc oxide slag mixture, and on the other hand, the pulp is stirred and mixed with the drugs, and the foam is refined at the same time, so that the zinc oxide adheres to the foam and floats to the liquid surface to form zinc oxide foam.

[0003] Most existing flotation machines directly suck the zinc oxide slag mixture and air into the impeller cavity for mixing, and then throw them out through the discharge port set on the side wall of the impeller cavity. The feed pipe is usually directly connected to the shaft sleeve, so that one end of the feed pipe faces the main shaft. Under the impact of the zinc oxide slag, the main shaft at the feed pipe wears faster. The traditional flotation machine separation mechanism uses a scraper to scrape the foam, but the liquid level in the flotation machine fluctuates, so the scraping effect of the scraper is greatly reduced, and there is a situation of insufficient scraping, which is prone to a large amount of residual Summary of the invention
