Description

Cooling water filter of water detecting and draining drilling machine

Technical Field

The application relates to the technical field of coal mine drilling, and particularly discloses a water detection and drainage drilling machine cooling water filter.

Background

When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others.

In the drilling process of coal mines, cooling water is often used for cooling a drilling machine, in order to save energy, the cooling water is derived from construction water treated by an underground sewage treatment station and water for detecting and dredging drill holes, but some weak cemented sandstones in coal-bearing strata of the coal mines develop and are hydrolyzed and disintegrated, so the cooling water generally contains gravel, the water is blocked when passing through a cooler of the drilling machine, the construction water is reduced, and the cooler is seriously worn.
