Abstract

The invention discloses a coal-water separation device and method for an underground downhill driving working face. The coal-water separation device comprises a driving mechanism, a transmission mechanism, a mud scraping plate, a compression plate and a water absorption sponge which are arranged in a filtering and water collecting shell; the water collecting pipe, the water collecting tank, the draining pump and the desilting opening are arranged at the lower part of the filtering and water collecting shell; holes are formed in the surface of the filtering water-collecting shell; the driving mechanism is fixedly connected with one end of the transmission mechanism; the other end of the transmission mechanism is fixedly connected with the compression plate for driving the compression plate to reciprocate up and down; the mud scraping plate is fixedly connected to the upper part of the compression plate and is used for cleaning coal gangue particles entering the filtering and water collecting shell; a water-absorbing sponge is arranged between the lower end of the compression plate and the bottom of the filtering water-collecting shell; the other end of the water collecting pipe is provided with a water collecting tank; a desilting opening is formed in the lower end of the water collecting tank; the other side of the water tank is connected with a drainage pump; the drainage pump outlet is connected with a drainage pipe. The coal-water separator is reasonable in structure, and coal and water can be rapidly separated.

Description

technical field [0001] The present application relates to the technical field of coal-water separation equipment used in coal mines, in particular to a coal-water separation device and method for underground tunneling face. Background technique [0002] In the production of underground coal mines, there are often problems such as untimely drainage of the downhill excavation working face, and the muddy water of the excavation working face is mixed and becomes paste, which leads to difficulties in coal extraction. When the belt and the single entry level are low, it will cause great difficulties in the production of the excavation face and cause certain safety hazards. In addition, when the above-mentioned pasty coal slime water mixture is transported to the excavation belt conveyor for discharge, it is easy to cause the belt conveyor to deviate seriously, sprinkling coal along the way, and the lower belt returns coal to block the belt conveyor roller at the end of the machine...
