Coal mine wastewater pretreatment device

Abstract

The invention relates to a coal mine wastewater treatment device, in particular provides a coal mine wastewater pretreatment device which is simple and reasonable in structure, easy to operate, good in filtering effect and low in running cost, and solves the technical problems. According to the technical scheme of the coal mine wastewater pretreatment device, a water inlet pipe is arranged at the top of a tank body, a water outlet pipe is arranged at the bottom of the tank body, a filtering material layer and a porous plate are arranged in the tank body, the filtering material layer is arranged above the porous plate, the water outlet pipe extends into the tank body, the top of the water outlet pipe is covered with an anti-scour plate, and an exhaust pipe is also arranged at the top of the tank body. The coal mine wastewater pretreatment device is widely used for treating coal mine wastewater.

Description

technical field [0001] The invention relates to a coal mine wastewater treatment device, in particular to a coal mine wastewater pretreatment device. Background technique [0002] With the continuous development of mining machinery and equipment, the degree of automation of coal mining machinery has also been continuously improved. As the most important coal mining equipment, hydraulic supports are playing an increasingly important role in mine production. In hydraulic supports that use emulsified water as a working medium in large quantities, the quality and composition of water have a great impact on the normal operation and service life of hydraulic supports. [0003] At present, coal mining produces a large amount of wastewater, which still cannot meet the standard of qualified industrial water after being separated at the bottom, and the water quality is relatively poor. Under such working conditions, the damage to coal mining equipment, especially the cooling ...

AI Technical Summary

Problems solved by technology

[0003] At present, coal mining produces a large amount of wastewater, which still cannot meet the standard of qualified industrial water after being separated by sinking, and the water quality is relatively poor.

Under such working conditions, due to water quality, the damage to coal mining equipment, especially the cooling system of the motor, the valve group of the hydraulic support, the jack, the column and other hydraulic components has increased significantly.

The maintenance cycle and service life of the equipment are shortened, and even cannot be used normally

This not only increases the maintenance workload of the equipment maintenance machine, but also increases the investment in equipment maintenance parts, which ultimately leads to an increase in coal mining costs
