Purification module and coal mine underground water purification system thereof

Abstract

The invention discloses a purification module and a coal mine underground water purification system thereof. The purification module comprises a mixing tank, a stirring tank and a settling tank; wherein the stirring tank comprises a stirring tank body, and a hollow stirring inner cavity is formed in the stirring tank body; a third mounting disc, a second mounting disc, a stirring wheel, a swingingdisc, another stirring wheel and a first mounting disc are sequentially mounted in the stirring inner cavity from bottom to top; the third mounting disc and the bottom of the stirring shaft can be circumferentially and rotationally assembled; the second mounting disc, the first mounting disc and the stirring drum can be circumferentially and rotationally assembled; the two stirring wheels sleevethe stirring drum in an axially slidably and circumferentially unrotatably matched manner; the swing disc is sleeved and fixed outside the mixing drum; a through stirring barrel drainage groove is further formed in the position, close to the first mounting disc, of the stirring barrel, a hollow stirring inner barrel is arranged in the stirring barrel, a water pumping auger is mounted in the stirring inner barrel, and the outer edge of the water pumping auger is tightly attached to the inner wall of the stirring inner barrel in a sealed mode and fixed to the stirring shaft in a sleeving mode.

Description

technical field [0001] The invention relates to underground water treatment technology and mining technology, in particular to a purification module 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 ef...

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
