Abstract

The invention discloses a pressure-driven impulse type pipeline washing brush which comprises a rotary shell, a front end cover, a rear end cover, a center shaft, a pressure pipe and at least two elastic brushes. The rotary shell is a hollow cylinder. The front end and the rear end of the rotary shell are sealed by the front end cover and the rear end cover correspondingly. The hollow center shaft stretches into an inner cavity of the rotary shell from the outside. Multiple nozzles in the same direction are arranged in the side wall of the rotary shell. An inner cavity of the center shaft and the inner cavity of the rotary shell communicate with the nozzles in sequence. The outer end of the center shaft is connected with a water feeding hose. The water feeding hose is used for access of high-pressure media. Rotating and advancing power is provided for the rotary shell through reacting force formed when nozzles eject the high-pressure media. The elastic brushes are fixed to the rear end of the rotary shell in the circumferential direction in a surrounding mode. Rotating and advancing power is formed when high-pressure liquid or gas is jetted by the nozzles to drive the elastic brushes to clean the inner wall of a pipeline, meanwhile, the media ejected by the nozzles can form an impulse type high-pressure washing effect on the inner wall of the pipeline, and the pressure-driven impulse type pipeline washing brush has the advantages that the cleaning effect is good, and the bent pipe passing rate is high.

Description

technical field

[0001] The invention relates to the technical field of industrial cleaning, in particular to a pressure-driven, pulsed pipeline flushing brush. Background technique

[0002] Pipelines are tubular devices used to transport gases or liquids. During the use of the pipeline, crystallization, dirt or residues will occur on the inner wall of the channel. If it is not cleaned in time and effectively, the normal use of the pipeline will be affected. Therefore, regular cleaning of the pipeline, especially the small diameter pipeline, is particularly important. In particular, nuclear pipes and heat transfer tubes of related heat exchangers need to be moderately cleaned before in-service inspection to meet the requirements of in-service inspection. At present, there are many commonly used pipeline cleaning technologies, generally speaking, there are two types of physical cleaning and chemical cleaning.

[0003] Physical cleaning includes high-pressure water jet cleani...

Embodiment Construction

[0023] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0024] Please refer to Figure 1-3 One embodiment of the pressure-driven, pulse-type pipeline flushing brush of the present invention includes a rotating housing 4, a front end cover 1, a rear end cover 7, a central shaft 12, a pressure tube 10, an elastic brush 13, and a positioning wheel device 11.

[0025] The rotating housing 4 is a hollow cylinder with a certain wall thickness, and the front and rear ends are respectively sealed by the front end cover 1 and the rear end cover 7 . The top end of the front end cover 1 is arc-shaped, and can also be designed as spherical, spiral or chisel-shaped according to requirements, which can be used to remove large dirt during the advancement of the rotating housing 4, and through the countersunk head screw 3 and the rotating housing 4 connection, adopt the fo...
