Coal mine underground solid-liquid separation and purification device

Abstract

The invention discloses a coal mine underground solid-liquid separation and purification device, and relates to the field of coal mine underground coal-water mixture separation. The device comprises a collecting pipeline, a diffuser, a settling tank and a driving mechanism, one end of the collecting pipeline is communicated with a mixture source, the other end of the collecting pipeline is connected with the diffuser, the diffuser is of a box structure, and turbulent flow plates are arranged on the middle and lower end faces of a box respectively; an overflow water tank is arranged on the side surface of the settling tank, and a drainage pipe is arranged at the lower part of the overflow water tank; and a discharging mechanism is arranged in the settling tank and is connected with a driving mechanism, and the driving mechanism is connected with a control mechanism. The device is suitable for environments such as underground coal mines and mines with sewage, is convenient to use and reliable in performance, meets the production requirements of the coal mines, replaces heavy manual labor with machinery, collects a coal-water mixture, separates and removes solid particles, and achieves the purposes of reducing manpower, improving efficiency and achieving safe production.

Description

technical field [0001] The invention relates to the technical field of coal-water mixture separation in underground coal mines, in particular to a solid-liquid separation and purification device for underground coal mines. Background technique [0002] In the coal-sliding well of the coal mining face, the small gangue-sliding well of the excavation face, and the lower wellhead of the main shaft for skip coal loading, there are fluids mixed with scattered coal and gangue particles and the underground roof spraying water or well shaft water gushing , called coal (gangue), water mixture. The mixture of coal (gangue) and water flows out of the coal (gangue) nozzle, which directly causes blockage of the roadway ditch, and then blocks the transportation track; when the mixture of coal (gangue) and water is loaded into the mine car, the solid particles stagnate at the bottom of the mine car It will cause the volume ratio of the mine car to decrease; the mixture of scattered coal a...

AI Technical Summary

Problems solved by technology

For a long time, the solid matter in the coal (gangue) and water mixture produced in the underground production of coal mines has been deposited manually, which is labor-intensive and has a low safety factor.

This situation is no longer suitable for the current coal mine production mode of reducing labor and improving efficiency, and safety first. Coal (gangue) and water mixture separation and purifier for automatic control of coal (gangue) and water mixture from the source

[0003] At the same time, during the production process of the coal mine, there is a large amount of coal (gangue) muddy water in the mining face due to dust fall, equipment cooling, and water gushing in the face, which will cause silting of ditches and water tanks during the drainage process. 1. The water tank consumes a lot of manpower and financial resources, and the blockage of the water tank ditch causes hidden dangers to the mine. This equipment can be used for the source treatment of sewage caused by coal (gangue) in coal mines
