Coal mine wastewater purification treatment equipment

Abstract

The invention relates to the technical field of wastewater treatment equipment and discloses coal mine wastewater purification treatment equipment. The equipment comprises a filter tank, wherein a partition plate is fixedly arranged on one side inside the filter box in a sleeving manner; a blow-down tank positioned on one side of the partition plate is fixedly arranged at the bottom of an inner cavity of the filter tank; and four positioning rods are fixedly connected to the top of the side face of the partition plate. According to the coal mine wastewater purification treatment equipment, coal mine wastewater passes through a first filtering net on a positioning frame and then drops into the bottom of the filter tank by virtue of the first filtering net. Meanwhile, one end of the adjusting rod is frequently contacted with the top of the positioning frame by utilizing a rotating disc, and the elastic force effect of the spring is matched, so that the first filtering net shakes at a certain frequency, and pulverized coal, slag and other sludge in the coal mine wastewater can conveniently drop into the blow-down tank. During filtration of the coal mine wastewater, the first filteringnet is not blocked by the pulverized coal, slag and other sludge, so that the filtering efficiency of the coal mine wastewater is improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to coal mine wastewater purification treatment equipment. Background technique [0002] With the advocacy of the concept of social environmental protection, the coal mine field is also paying more and more attention to environmental protection mining of coal mines. Since the wastewater generated during coal mining contains a large amount of sludge such as coal powder and slag, it is necessary to purify the coal mine wastewater to prevent the coal mine wastewater from being harmful to the environment. Pollution of surrounding waters. [0003] Aiming at the defects of the prior art, Chinese patent (publication number: CN103432803B) has proposed a kind of sewage circulation treatment system and mining machinery, the advantage of this sewage circulation treatment system and mining machinery is that operation efficiency is high, and the sewage in the sewage can be ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a kind of coal mine wastewater purification treatment equipment, which has the advantages of preventing the clogging of the filter screen and preventing the secondary pollution of the sediment to purify the water, and solves the problem of the sewage circulation treatment system and mining machinery in filtering the coal mine When there is sludge such as coal powder and slag in the wastewater, the filter screen is easy to accumulate sludge such as coal powder and slag, which makes the filter screen clogged, thereby affecting the filtration efficiency, and the sewage circulation treatment system and mining machinery are added to the coal mine wastewater During the purification process, when the water is extracted after the solids in the wastewater have settled, there will be fluctuations in the water, and the sediment in the water is easy to re-mix with the water, thus affecting the purification quality of coal mine wastewater
