Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment and reuse, and specifically relates to a magnetic separation device suitable for underground treatment of mine water. Background Art

[0002] Mine water refers to the water that flows into the mine from various sources during the mining process. This water has undergone a series of physical, chemical and biochemical reactions when the groundwater comes into contact with the coal seam and rock layer, and is affected by human activities. Therefore, the water quality has significant characteristics of the coal industry: high concentration of suspended matter, small particles that are difficult to precipitate, and contains organic pollutants such as waste oil and emulsified oil. Therefore, the discharge of mine water not only pollutes the environment, but also causes a large amount of waste of limited water resources and coal powder. Improving the utilization rate of mine water has dual significance for the development of the coal industry and environmental protection. In particular, the removal of suspended matter has become an essential and important stage in the mine water treatment process.

[0003] In the existing mine water treatment device, the stirring mechanism is fixed by bolts. After long-term use, sludge is easily attached to the surface of the stirring blade, resulting in secondary pollution of the water quality when the mine water is subsequently mixed with the flocculant, further increasing the intensity of the mine water treatment work. Therefore, a magnetic separation device suitable for underground mine water treatment is proposed to solve the above problem. Utility Model Content
