Water gas mixing pipeline cleaning machine and control method thereof

Abstract

The invention relates to a water gas mixing pipeline cleaning machine. The water gas mixing pipeline cleaning machine comprises a rack, a control system, a high-pressure air pipe, a water pump and a corresponding cleaning liquid pipeline; the high-pressure air pipe and the cleaning liquid pipeline are connected through a tee joint, the outlet end of the tee joint is connected with a work pipeline, an electromagnetic air inlet valve is arranged on the high-pressure air pipe, the water pump is arranged on the cleaning liquid pipeline, a spiral guide groove is formed in the inner wall of the outlet end of the work pipeline, a through hole is formed in the pipe wall of the rear end of the spiral guide groove, the through hole is connected with an air guide pipe, the air guide pipe is arranged in the tangent direction of the spiral guide groove, and the air guide pipe is communicated with the air outlet end of the electromagnetic air inlet valve. According to a control method of a water gas mixing pipeline cleaning machine, after the airflow enters the pipeline, disturbance is large, and the washing capacity of the inner wall of the pipeline is large.

Description

technical field [0001] The invention relates to pipeline cleaning equipment, in particular to a water-gas mixing cleaning machine. Background technique [0002] Pipeline cleaning is a relatively complicated cleaning work, which generally requires certain equipment or specific materials. At present, strong acid and strong alkali are mainly used for corrosive cleaning. This method is easy to cause corrosion to the pipe wall and shorten the service life of the pipe; Another method is to use a high-pressure impact method to forcibly wash away the dirt on the inner wall of the pipe. This method is likely to cause physical damage to the pipe wall. [0003] In order to solve this problem, the Chinese patent with the publication number CN 204470220U discloses a multifunctional pipeline pulse cleaning device, including a water-air mixing pulse generator and a suction pump, and the water-air mixing pulse generator and the suction pump are electrically connected The central controller...

AI Technical Summary

Problems solved by technology

However, its structure is relatively complicated, and a reasonable, convenient, efficient and reliable control system cannot be provided.

Moreover, since the high-pressure gas in this technical solution enters the pipeline to be cleaned approximately in a straight line, the deflection of the airflow entering the pipeline is relatively small, and its ability to scour the inner wall of the pipeline is relatively small.
