Pipe inner wall cleaning device and cleaning method

Abstract

The invention discloses a pipe inner wall cleaning device. The pipe inner wall cleaning device comprises a supporting base, a sweeping device arranged on the supporting base, an advancing device and afeedback control device; the sweeping device comprises a cleaning air pipe, a compressed air pipe connected with the tail end of the cleaning air pipe and a rotating device used for driving the cleaning air pipe to rotate; the advancing device is used for pushing the sweeping device to move in the axial direction of a pipe and comprises a wheel assembly installed on the supporting base and a first driving motor driving the wheel assembly to rotate; and the feedback control device comprises a detector used for detecting whether the sweeping device moves to the tail end of the pipe or not and acontroller electrically connected with the detector. The pipe inner wall cleaning device can clean the inner walls of pipes with different lengths, and is good in cleaning effect, easy to operate andlow in energy consumption. The invention further provides a pipe inner wall cleaning method.

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a pipe inner wall cleaning device and cleaning method. Background technique [0002] Most steel pipes will produce impurities such as rust, welding slag, dust, sand, cement, and insulation materials during the process of manufacturing, storage, transportation, and installation; Rust inhibitor, etc. [0003] The cleaning of the outer surface of the pipe is easy to solve, but the inner wall is more difficult. At present, solvent oil (gasoline, kerosene) or a certain concentration of acid-base decontamination cleaning solution is used for soaking. When the surface quality of the pipe is high, it is necessary to increase the cleaning steps of heating and brushing. There is also a method of putting the pipe into an ultrasonic cleaning device for cleaning. These methods either have insufficient security and high energy consumption, or the equipment is large in size...

AI Technical Summary

Problems solved by technology

These methods are either insufficient in safety and consume a lot of energy, or the equipment is large in size, low in efficiency, and inconvenient to operate

[0004] In the prior art, there is also a method of using a high-pressure water gun to perform high-pressure water jet stripping and cleaning of the dirt on the inner surface of the pipeline. The cleaning process will cause waste of water resources, and wastewater treatment of sewage is also a relatively large project. At the same time, high-pressure water washing is used In this method, the method of moving to adapt to the length of the steel pipe also needs to increase the device. After adding the device, there will still be a problem that the water pipe used when the steel pipe is too long needs to be the same length as the steel pipe, otherwise the whole steel pipe cannot be cleaned. It cannot effectively improve the cleaning efficiency of steel pipes; at the same time, the waste water generated after cleaning steel pipes is also a big problem
