Description

Technical Field

[0001] This application relates to the technical field of pipeline processing, and particularly to a rust removal and anti-corrosion treatment device for large metal pipelines. Background Art

[0002] After general metal pipelines are used for a long time, rust and corrosion will occur. Therefore, anti-corrosion treatment needs to be carried out on the metal pipelines. After being processed by the anti-corrosion process, it can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reactions during transportation and use, effectively prevent or slow down corrosion, extend the service life of the steel pipes, and reduce the operation cost of the steel pipes. The anti-corrosion treatment first requires surface treatment of the pipeline, smoothing the surface of the pipeline so that there are no burrs and rust spots on its surface. Only after surface treatment can the preliminary spraying of rust prevention treatment be carried out.

[0003] Currently, shot blasting for rust removal is mostly used. However, the existing shot blasting rust removal equipment cannot well meet the needs of pipelines with different specifications and sizes, especially pipelines with longer sizes for rust removal, and there is no environmental protection treatment supporting equipment that can match it well, resulting in more dust and greater pollution. Therefore, a rust removal equipment is needed to meet the rust removal and anti-corrosion treatment of pipelines and meet environmental protection requirements. Summary of the Utility Model
