Filter and coal mine underground water purification system thereof

Abstract

The invention relates to a filter and a coal mine underground water purification system thereof; the filter comprises two filter side plates, a filter shell and a filter screen, and the two filter side plates are respectively fixed at openings at two sides of the filter shell; an overflow shell is mounted at the top of the filter shell, an overflow weir is formed between the inner side of the overflow shell and the outer wall of the filter shell and communicates with the top of a water collecting tank in the water collecting shell, the bottom of the water collecting tank communicates with oneend of an overflow pipe, and the other end of the overflow pipe communicates with a purification water inlet pipe of a secondary purification module; a hollow filter cavity is formed in the filter shell, a V-shaped groove with the width gradually decreased from top to bottom is formed in the bottom of the filter cavity, a sludge auger is arranged in the V-shaped groove, a sludge auger shaft is fixedly sleeved with the sludge auger, and one end of the sludge auger shaft penetrates out of the filter shell and then is fixedly assembled with an output shaft of a sludge auger motor; countless through filter holes are formed in the filter screen, and a filter drain pipe is arranged above the filter screen and is used for conveying water filtered by the filter screen to a purification water inletpipe of a main purification module.

Description

technical field [0001] The invention relates to underground water treatment technology and mining technology, in particular to a filter and a coal mine underground water purification system. Background technique [0002] In the process of underground coal mining, due to the infiltration of groundwater, a large amount of underground wastewater will be produced, which contains a large amount of solid particles, suspended solids, engine oil, etc., so it cannot be directly used for underground production. At present, the underground wastewater is mainly pumped out of the surface through water pumps, purified by the equipment on the surface, and then pumped back to the underground for coal cutters, dust removal, and domestic use. Obviously, a large amount of energy consumption will be generated in this process. Although there is currently a technology for purifying underground wastewater directly underground, this equipment is large in size and low in purification efficiency, so ...

AI Technical Summary

Problems solved by technology

Although there is currently a technology for purifying underground wastewater directly underground, this equipment is large in size and low in purification efficiency, so it cannot meet the purification of underground wastewater, and the purified water produced cannot meet the needs of underground mining. tasteless
