AI Technical Summary

Technical Problem

Existing sandblasting equipment lacks an active cleaning mechanism when cleaning rust on the inner walls of metal pipes, resulting in incomplete cleaning and easy re-adhesion of some debris, requiring additional cleaning afterwards.

Method used

A rust removal and cleaning device for the inner wall of metal pipelines in chemical construction was designed. It combines a sandblaster and a cleaning device, including a nozzle, a support, a receiving block, a fixing frame, a fixing ring, and a cleaning brush. The sandblaster drives the cleaning brush to move, which helps to clean the inner wall of the pipeline. The device also increases the sealing performance and reduces the residue of debris through structures such as limit blocks and magnetic blocks.

Benefits of technology

It enables real-time cleaning of the pipe inner wall during sandblasting, reducing subsequent cleaning time, improving cleaning efficiency and sealing, and reducing debris residue.
