AI Technical Summary

Technical Problem

In the prior art, a large amount of abrasive particles and dust remain on the surface of the pipeline after sandblasting and rust removal, affecting the adhesion of the subsequent coating, leading to problems such as coating peeling and blistering, and reducing the anti-corrosion performance and service life of the pipeline.

Method used

A rust removal device for pressure pipelines in water conservancy projects is designed, including sandblasting body, air extraction assembly and cleaning assembly. The exhaust assembly forms an air passage through the partition and the exhaust pipe, and uses the airflow to suck away particles on the surface of the pipe. The cleaning rollers and bristles in the cleaning assembly clean the surface of the pipe to ensure that the particles are effectively sucked away.

Benefits of technology

Through the use of this device, particles on the surface of the pipeline can be effectively cleaned, cleaning efficiency can be improved, particle residues can be reduced, environmental cleanliness, labor intensity can be reduced, and maintenance costs can be reduced.

Abstract

The present invention relates to the technical field of pipeline rust removal, and in particular to a rust removal device for a hydraulic engineering pressure pipeline, which comprises a sandblasting body, wherein a buffer chamber 1, a rust removal chamber and a buffer chamber 2 are provided inside the sandblasting body; a partition 1 and a partition 2 are provided on the top of the buffer chamber 1, and the partition 1, the partition 2 and the inner wall of the sandblasting body cooperate to form an exhaust passage extending in the front-to-back direction, the top of the buffer chamber 1 is connected with an exhaust pipe, the bottom surface of the partition 2 abuts against the outer surface of the pipeline, and a gap is left between the bottom surface of the partition 1 and the outer surface of the pipeline, and a cleaning roller extending axially forward and backward and rotating around its own axis is provided in the exhaust passage, and the bristles on the cleaning roller abut against the outer surface of the pipeline. The present invention can perform sandblasting and rust removal on the pipeline surface, and then clean and collect particles attached to the pipeline surface, thereby improving the cleaning efficiency and reducing the situation where particles are scattered everywhere.
