Abstract

The invention discloses a high-efficiency and environmentally friendly sewage treatment equipment for coal mines, which relates to the technical field of coal mine sewage treatment equipment; in order to facilitate the removal of coal powder floating on the water surface; it specifically includes a main body, and the top and bottom of the main body are respectively provided with a water inlet and a discharge port. The top of the main body is fixed with a motor by screws, and the output end of the motor is connected to the rotating main shaft through a coupling. There are two symmetrical interlocking protrusions extending outward. The present invention uses the buoyancy of the annular air bag to make the lifting vane always adapt to the liquid surface by arranging structures such as an annular air bag and a connecting frame. Flowing through the surface of the lifting blade, when the flocculant is added through the dosing port, it can fully absorb the pulverized coal at the liquid surface, effectively solving the problem that the pulverized coal at the liquid surface is not easy to settle.

Description

technical field [0001] The invention relates to the technical field of coal mine sewage treatment equipment, in particular to high-efficiency and environment-friendly sewage treatment equipment for coal mines. Background technique [0002] In the process of coal mining, due to the natural drainage of the coal-measure aquifer by the water-conducting fissures generated during the mining process and the artificial drainage and drainage to ensure safety, the underground water resources of the coal mine are jointly polluted and destroyed. ; In order to ensure environmental sanitation and safety, coal mine sewage treatment is a necessary task. Although most of the current sewage treatment devices can meet certain sewage treatment needs, due to the hydrophobicity of coal itself, some tiny coal powder in the coal washing wastewater is in the water. Especially stable, some ultra-fine coal powder floats in the water, and it will not settle naturally after standing for several months; ...
