Description

Technical Field

[0001] The utility model relates to the technical field of mineral flotation, in particular to a rotary air-filled flotation machine. Background Art

[0002] Froth flotation is often used to separate fine particles of minerals. Compared with shaking table separation, high gradient magnetic separation and oil aggregation, bubble flotation has better efficiency and lower cost. The main principle of flotation is based on the difference in the surface chemical properties of minerals and slag, and the natural hydrophobicity of the surface of mineral particles and the hydrophilicity of slag are used to separate minerals and impurities.

[0003] During actual use, if the performance of the air pressurizing pipe or compressor is unstable, it may lead to an uneven air input, resulting in uneven concentration and distribution of the mixed gas. If the design of the rotating shaft makes it impossible to evenly disperse the air when the rotor rotates, it may lead to insufficient mixing of the air and the liquid. If the layout of the third fixed block and the fourth fixed block is unreasonable, they may not be able to effectively support and guide the rotating shaft, resulting in uneven air distribution. If the structural design of the outer casing and the rotating assembly is not adapted to the required fluid dynamics characteristics, the air may not be evenly dispersed before entering the liquid. Improper control of the motor speed, gas flow and liquid flow may lead to uneven mixing of the air and the liquid. Utility Model Content

The second fixed block, as a part of the gas path, provides structural stability, ensures the continuity and stability of gas transmission, and can flexibly adjust the mixing ratio of gas and liquid by adjusting the size and shape of the air pressurizing pipe and the slot to adapt to different process requirements.
