Automatic mechanical defoaming barrel for mineral flotation

Abstract

The utility model discloses an automatic mechanical defoaming barrel for mineral flotation, which is characterized in that a protruding component on the inner wall of an outer defoaming barrel is matched with a protruding component fixed on the outer wall of an inner defoaming barrel, the inner defoaming barrel and the outer defoaming barrel are arranged at reasonable relative positions, and an annular cavity is formed between the inner defoaming barrel and the outer defoaming barrel; the automatic mechanical defoaming barrel for mineral flotation is formed by the aid of an axial center stirring system in the outer defoaming barrel, an outer spraying system arranged in the annular cavity, a defoaming system and an air exhaust system arranged in the inner barrel, a liquid inlet in the outer defoaming barrel and a liquid outlet in the bottom of the outer defoaming barrel. The defoaming is carried out on the foam layer, secondary foam production is avoided, high-pressure spraying, centrifugal defoaming and vacuum defoaming are compositely applied, the mineral flotation defoaming efficiency is improved, disassembly and adjustment are convenient, the defoaming amount and the defoaming speed of the defoaming barrel can be adjusted at any time according to the actual site situation, the application range is wider, and the defoaming barrel has excellent application prospects.
