Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, and more specifically, to a self-priming slurry flotation machine. Background Technology

[0002] Flotation machine is short for flotation mineral processing machine. It refers to mechanical equipment that completes the flotation process. In the flotation machine, after the slurry is treated with reagents, it is stirred and aerated, so that some mineral particles are selectively fixed on the air bubbles and float to the surface of the slurry to be scraped off to form a froth product. The rest remain in the slurry, so as to achieve the purpose of separating minerals.

[0003] A search revealed that utility model patent CN209577041U discloses a high-ash coal slime flotation machine, aiming to improve flotation machine efficiency and increase clean coal recovery rate. Specifically, the flotation machine includes a tank; a spray device located on the upper edge of the tank, solving the problem of severe foam "back ash"; a slurry pretreatment tank connected to one side of the tank, solving the problem of insufficient solid-liquid and reagent mineralization of the slurry before flotation; a concentrate recovery bin connected to the other side of the tank, solving the problem of easy leakage of clean coal; a pipeline connecting a gate valve to a stirring device, solving the problem of insufficient slurry intake and easy turbulence formation in the tank when the stirring device relies on the self-suction of slurry overflowing from the tank; and a gate valve connecting two tanks, solving the problems of non-sealing gates, large gaps, material entering other tanks before sufficient flotation, and uncontrollable slurry flow.

[0004] However, the aforementioned patents still have the following shortcomings: the slurry mixed in the slurry pretreatment tank can only enter the flotation chamber by its own weight, making it inconvenient to smoothly add the slurry into the flotation chamber; in addition, the quality of stirring the slurry and reagents by relying on the stirring wheel and drop plate needs to be improved. Therefore, we propose a self-priming slurry flotation machine. Utility Model Content
