Problems solved by technology

Since the coal-water separation in the sedimentation tank adopts a static determinate method, the treatment cycle is longer and the cycle of water recycling is longer, resulting in waste of water resources and lower production efficiency; When leaving, some clean coal will be taken away, wasting coal resources and polluting the environment at the same time

Abstract

The invention discloses a coal washing discharge device comprising a cleaned coal conveyer and a centrifugal hydroextractor; the centrifugal hydroextractor comprises a centrifuge dewatering assembly and a drive unit; the centrifuge dewatering assembly comprises a housing, a liquid throwing cylinder and a receiver sleeved in sequence; a discharge path of a material receive chute is connected with a finished material conveyer; a water outlet of a water receive groove is connected with a water processing device; a clean water outlet of the water processing device is connected with a water supply pool of a coal washer; the water and coal can instantly attach on the liquid throwing cylinder under centrifugal force, the water can flow through screen holes on the liquid throwing cylinder wall and enters the water receive groove along an interlayer, so cleaned coal after washing operation can be fast and thoroughly dehydrated, and dehydrated cleaned coal and sewage water can be fast separated; the water can be recovered and utilized in a short term, thus preventing long term static setting, improving production efficiency; compared with a sedimentation basin, the coal washing discharge device takes almost no land occupation, thus reducing investment and labor working, and reducing production cost.

Description

technical field [0001] The invention relates to a post-processing device for coal washing in a coal washing plant, in particular to a coal washing and discharging device. Background technique [0002] Jig coal washing is a coal washing method commonly used in coal washing plants, which has the advantages of low cost, high efficiency and convenient operation. The coal washing and discharging device includes a raw material screening device, a crushing device, a jig and a material conveying device, and the material conveying device includes a finished material conveying device and an impurity material conveying device. After the coal washing work is completed, the finished coal is discharged to the designated area through the coal washing discharge device. [0003] In the prior art, the finished coal after coal washing is directly discharged to the sedimentation tank, and the coal and water are separated through the sedimentation tank. Since the coal-water separation in the s...
