Magnetic separator and coal mine underground water purification system thereof

Abstract

The invention relates to a magnetic separator and coal mine underground water purification system thereof. The magnetic separator comprises a magnetic separation tank, a magnetic separation cavity isformed in the magnetic separation tank, openings are formed in the two ends of the magnetic separation tank, and the two opening ends of the magnetic separation tank are assembled with a group of magnetic separation plates and a magnetic separation frame respectively; two opening ends of the magnetic separation cavity are respectively in circumferential rotation and sealing assembly with one magnetic sealing disc, at least one magnetic plate mounting seat is mounted on the magnetic sealing disc along the circumferential direction of the magnetic sealing disc, and the two coaxial magnetic platemounting seats are respectively assembled and fixed with two ends of a magnetic adsorption plate; the two magnetic separation plates are fixedly assembled with a gathering pipe, a hollow gathering cavity is formed in the gathering pipe, a gathering shell is arranged at the position, corresponding to the magnetic adsorption plate, of the gathering pipe, a hollow gathering groove is formed in the gathering shell, the gathering groove communicates with the gathering cavity, and the end, away from a magnetic return pipe, of the gathering cavity is a closed end; an upper scraping plate and a lowerscraping plate are arranged above the gathering groove, and are respectively clung to the two end surfaces of the magnetic adsorption plate passing through the gap of the upper scraping plate and thelower scraping plate, so that magnetic seeds on the magnetic adsorption plate are scraped off.

Description

technical field [0001] The invention relates to underground water treatment technology and mining technology, in particular to a magnetic separator 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 eff...

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
