Washing device for inner wall of water-coal-slurry pipe

Abstract

The invention relates to a washing device for the inner wall of a water-coal-slurry pipe. The washing device comprises a front stator, a support column and a rear stator, wherein one end of the support column is fixedly connected with one end of the front stator, and the other end of the support column is fixedly connected with one end of the rear stator; a washing head is arranged at the other end of the front stator, and at least three groups of first support legs are uniformly distributed on the peripheral surface of the front stator; an adapter is arranged at the other end of the rear stator, and at least three groups of second support legs are uniformly distributed on the peripheral surface of the rear stator; the washing head is connected with the adapter through a guide pipe; a roller and a second motor driving the roller are arranged at the bottom ends of each group of second support legs; and the washing head comprises a shaft, a disc, a rubber leaf and a piston rod. The washing device for the inner wall of the water-coal-slurry pipe has the advantages that the front stator uniformly provided with at least three rollers and the rear stator uniformly provided with at least three driving rollers are arranged at the two ends of the support column, so that the washing device, free of rail devices in the prior art, can more flexibly walk.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device for the inner wall of a coal-water slurry pipe. Background technique [0002] Before the present invention was made, the existing coal-water slurry pipeline dredging equipment mainly dredged the small-section coal-water slurry pipeline, but the coal slurry dirt on the wall of the coal-water slurry pipeline could not be removed from the entire section, and it was not completely cleaned for a long time It will make the coal slurry dirt on the section of the pipeline continue to accumulate, leading to the gradual narrowing of the section, so that the running resistance of the coal-water slurry in the pipeline increases, and the transportation efficiency of the pipeline decreases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cleaning device for the inner wall of a coal-water slurry pipe, by distributing at least...
