Description

TECHNICAL FIELD

[0001] The utility model relates to ore flotation technical field, concretely is a kind of flotation concentrate defoaming device. BACKGROUND

[0002] Flotation concentrate defoaming refers to the process of treating the foam generated in the process of gas flotation of ore pulp, so that it is separated, broken and disappeared. In the flotation operation of mining industry, the formation of foam is necessary, because it helps to separate the strong hydrophobic mineral (such as coal, metal sulfide, etc.) from the strong hydrophilic mineral (such as gangue). Mineral particles will adhere to the bubbles, and the foam layer rich in valuable minerals will be collected as concentrate as the bubbles rise to the liquid surface.

[0003] The prior art gradually scrapes the foam on the upper layer of ore pulp in one direction by using multiple scraping fan blades, or uses a convex shaft to drive a rod to rotate to make the scraper connected to the rod reciprocate to scrape the foam on the upper layer of ore pulp and then uses a defoaming agent to defoam the foam.
