Description

Technical Field

[0001] The utility model belongs to the technical field of flotation machines, and particularly relates to an impeller assembly of a flotation machine. Background Technique

[0002] The flotation machine is driven by an electric motor through a V-belt drive to rotate the impeller, generating a centrifugal force to form a negative pressure. On the one hand, sufficient air is inhaled to mix with the pulp, on the other hand, the pulp is stirred to mix with the drug, and at the same time, the foam is refined, so that the minerals adhere to the foam, float to the pulp surface and then form mineralized foam; the height of the gate plate is adjusted to control the liquid level, so that the useful foam is scraped out by the scraper. After the materials are fully mixed, they are fed into the bottom of the first chamber of the flotation machine. After the impeller rotates, a negative pressure is formed in the impeller cavity, so that the pulp under the trough and in the trough enters the mixing area from the lower suction port and the upper suction port of the impeller respectively, and the air also enters the mixing area along the air guide sleeve. The pulp, air and reagent are mixed here;

[0003] The existing impeller rotates to inhale pulp, air, etc. for mixing during use, and stirs and mixes through the impeller blades during use. During mixing, simple stirring will result in insufficient mixing, thus affecting the flotation of the pulp and requiring multiple flotations, which affects the efficiency. Therefore, it is necessary to design an impeller assembly of a flotation machine to solve the above problems. Summary of the Utility Model
