Anti-corrosion coating device for inner pipe wall of metal pipeline

Abstract

The invention discloses an anti-corrosion coating device for an inner pipe wall of a metal pipeline, and belongs to the technical field of metal product processing. Through the communication cooperation of a magnetic adsorption feeding vertical pipe and an arc-shaped coating plate, a magnetic block repeatedly moves up and down under the magnetic changing environment of an electromagnet, therefore,the coating in a material storage cavity is continuously guided into the magnetic adsorption feeding vertical pipe through a material suction pipe, the coating is guided into the arc-shaped coating plate through the magnetic adsorption feeding vertical pipe under the condition that the magnetic block is reversely pushed, and the coating is diffused to an arc-shaped coating surface layer through amaterial guide diffusion mechanism in the arc-shaped coating plate, in the process that the arc-shaped coating surface layer is attached to the inner pipe wall of the pipeline in a rotating mode, theinner pipe wall is coated with the coating on the end face of the arc-shaped coating surface layer, meanwhile, hot air is guided into the material storage cavity according to the refrigeration and the refrigeration principle of the two different ends of a semiconductor chilling plate, coating condensation is effectively avoided, cold air is derived outwardly through an air jet hole, and the derived cold air is in contact with the pipe wall, thus the coating on the pipe wall is easy to dry.

Description

technical field [0001] The invention relates to the technical field of metal product processing, in particular to an anti-corrosion coating device for inner pipe walls of metal pipes. Background technique [0002] As the superiority of pipeline transportation is becoming more and more recognized by people, the medium used to construct pipelines is becoming more and more complex, but pipeline protection measures cannot always keep up. In recent decades, the perforation of a large number of pipelines has been seriously damaged. In addition to polluting the environment by causing accidents such as running, leaking, and leaking, it is also very easy to cause explosions and fires. Especially in the construction of oil and gas pipelines, it is very important to realize the safe operation of pipelines. Minimizing the harm caused by pipeline corrosion is not only an economic problem, but also a social problem. [0003] In the prior art, the anti-corrosion function of the pipe wall ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the anti-corrosion function of the pipe wall is achieved by spraying anti-corrosion paint on the inner wall of the pipe. In actual operation, it is easier to implement anti-corrosion measures for large-diameter metal pipes. However, for small-diameter and long-diameter pipes The anti-corrosion of metal pipes is difficult to implement anti-corrosion in the pipe due to the limitation of the pipe diameter. The effect of spraying the pipe wall needs to be improved. At the same time, because the pipe is narrow and long, the coating on the pipe wall is not easy to dry quickly.
