Negative pressure drainage movable type water slag separating device

Abstract

The invention relates to a negative pressure drainage movable type water slag separating device. The negative pressure drainage movable type water slag separating device comprises a water slag collecting mechanism, a negative pressure pipeline, a connecting hose and a water slag separating mechanism; the negative pressure pipeline provides a negative pressure for the water slag collecting mechanism to collect water slag, and conveys the water slag to the water slag separating mechanism through the connecting hose to separate the water slag; the water slag collecting mechanism comprises a pneumatic motor, a collecting hopper, a first walking wheel and two impellers; the pneumatic motor rotates to drive the two impellers to move for carrying the water slag into the collecting hopper from a water slag inlet; the negative pressure pipeline comprises a negative pressure suction pipe, a J-shaped air pipe and a negative pressure connector; and compressed air enters the negative pressure suction pipe through the negative pressure connector and the J-shaped air pipe to generate a downward negative pressure, and the water slag in the collecting hopper is conveyed into the water slag separating mechanism for separation through the connecting hose. The device is reasonable in structure, rapid in separation of wastewater and coal slag, light in operation, convenient to move, good in separation effect and convenient to operate and maintain, and has good market prospect and development space compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of gas-water-slag separation equipment for mining underground roadways, in particular to a negative pressure pumping and discharging mobile water-slag separation device. Background technique [0002] During the process of drilling, mining, screening and transportation of coal mines, a large amount of dust and coal ash will inevitably be produced. Workers who work for a long time are easily attacked by pneumoconiosis. In addition, the underground tunnels full of dust will seriously hinder the progress of mining and production. The vision of the transportation roadway brings hidden safety hazards to workers' health and underground work. In order to reduce the dissipation of coal powder, the mining face will be continuously flushed during the drilling process, so that the coal powder generated during the drilling process is mixed with water flow. Formation of coal slag. [0003] At present, the water slag unde...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the coal slag formed by the mixed water flow of pulverized coal in the process of drilling, mining, screening and transportation in existing coal mines, the slag flows along the roadway to the low-lying collection box, and the water seeps out from the gap after the slag is collected. Workers Put the remaining cinders on the belt and carry them away; a large amount of water is stored in the roadway, and the cinders accumulate in the roadway, which brings great disadvantages to the roadway and the workers, and affects the normal operation of underground work. The invention provides a negative pressure drainage mobile Water slag separation device, to achieve the purpose of reasonable structure, ingenious design, rapid collection of waste water cinder, fast separation, good separation effect, light operation and convenient movement
