An anti-corrosion spraying processing equipment for the inner and outer walls of the pipeline

Abstract

The present invention belongs to the technical field of pipeline anticorrosion, especially a kind of anticorrosion spraying processing equipment for the inner and outer walls of pipelines. The following scheme is proposed, including a processing table and two spraying plates, and the outer walls of the opposite sides of the two spraying plates are equidistant from each other. Spraying holes are opened, and the outer walls on both sides of the two spraying plates are fixedly connected with wind force limiting components, and the wind force limiting components include wind force plates. The present invention is provided with a hollow frame, a partition and a heating hole. During the process of spraying the anticorrosion paint, the partitions distributed equidistantly outside each spray hole differentiate the sprayed anticorrosion paint to avoid uneven spraying. When the gas is delivered to the wind panel, part of the gas enters the interior of the separator and is sprayed out through the heating hole, which plays a preliminary heating effect on the anti-corrosion paint. The gas ejected from the heating hole prevents the anti-corrosion paint from adhering to the separator and causing loss, further improving the effect of anti-corrosion spraying and the usefulness of the device.

Description

Technical field [0001] The present invention relates to the technical field pipeline corrosion, in particular, it relates to an apparatus for processing anti-corrosion coating for the pipe outer wall. Background technique [0002] Pipeline corrosion refers to slow or prevent the pipes in chemical, electrochemical action inside and outside the media or by the metabolic activity of microorganisms and erosion and deterioration of the measures; description of pipeline corrosion corrosion phenomena can be understood as material in their environment in a chemical reaction occurs, the reaction may cause the loss of the piping components and results in a line or even the entire pipeline system failure; in the pipeline system, the corrosion is defined as: based on the particular pipeline environment, in all metal and non-line system chemical reaction of metal material, the electrochemical reactions and microbial attack, and the reaction may result in damage to the pipeline structure and t...

AI Technical Summary

Problems solved by technology

[0003] When the existing pipeline anti-corrosion spraying processing equipment sprays anti-corrosion paint on the inner and outer walls of the pipeline, because the inner and outer walls of the pipeline are arc-shaped structures, after spraying the anti-corrosion paint, the anti-corrosion paint tends to slide down from the inner and outer walls of the pipeline. As a result, the stock of anti-corrosion paint on the inner and outer walls at the top is the lowest, and there are more anti-corrosion paint near the middle and lower sections, and the effect of anti-corrosion spraying on some positions is poor. The interference of factors, the wind is easy to make the outer layer of anti-corrosion paint fall off, therefore, in the process of spraying, it needs to be quickly heated and solidified to make it adhere to the inner and outer walls of the pipeline. lower
