Pipe cleaner for removing black powder

Abstract

The invention discloses a pipe cleaner for removing black powder. The pipe cleaner comprises a hollow spindle with two closed ends, wherein a front flange and a back flange are mounted on the hollow spindle, a pipe sealing disc I fixedly connected with the front flange is arranged in front of the front flange, and a pipe sealing disc II fixedly connected with the back flange is arranged at the back of the back flange; at least one circle of steel brush group is arranged on the external circle of the hollow spindle located between the front flange and the back flange and comprises multiple steel brush assemblies distributed circumferentially and evenly; each steel brush assembly comprises a mounting base elastically connected with the hollow spindle, a permanent magnet and a steel brush are mounted on the mounting base, the steel brush is placed on the upper surface of the permanent magnet, and the steel brush and the permanent magnet are fixedly connected with the mounting base respectively. The pipe cleaner adopts such a structure that the permanent magnets are fixedly mounted on the steel brush mounting bases and used for producing magnetic force, so that the whole pipe cleaner is magnetic, particularly the steel brushes become magnetic steel brushes, the attraction force to the black powder is increased, and the black powder carrying and cleaning capability is improved.

Description

technical field [0001] The invention relates to a pipe cleaner, in particular to a black powder pipe cleaner. Background technique [0002] Since the pipelines are placed on site for a long time during the construction period, the high temperature, hot and humid weather will cause serious rust on the inner wall of the gas pipeline without internal coating. In addition, due to the water contained in the transported gas, the inner wall of the gas pipeline will also be rusted. These rust and other impurities form black powder, which is adsorbed on the pipe wall in powder form, which increases the roughness of the pipe wall and reduces the transportation efficiency of the pipe. At the same time, a large amount of rust will also make it impossible to carry out in-pipeline inspection, making the pipeline corrosion situation out of control. [0003] At present, the widely used pipeline pig in the industry is the wire brush pig, which relies on the seal between the sealing disc an...

AI Technical Summary

Problems solved by technology

Due to the low hardness of the steel wire brush, it will deform during operation, which makes the cleaning effect of the black powder unsatisfactory

At the same time, due to the excessive length of the pipeline, the sealing disc will be greatly worn, resulting in incomplete removal of the removal and poor cleaning effect

Therefore, at least dozens of pigging operations are required for long-distance pipelines, which increases working time and pigging risks
