Powder room for suction coating in pipelines

Abstract

The invention discloses a powder room for suction coating in pipelines. The powder room comprises a room body, a powder bucket, a vacuum dust suction device and a clamping rotation device, wherein thepowder bucket is arranged on the room body and used for storing a powdery anticorrosion coating; the vacuum dust suction device is arranged on the room body and can be used for sucking out the anticorrosion coating in the powder bucket communicated with the vacuum dust suction device; the clamping rotation device is arranged on the room body; first suction coating channels are arranged on the clamping rotation device; clamping heads are also arranged on the clamping rotation device and used for clamping one ends of pipelines to ensure that one ends of the first suction coating channels are communicated with inner holes of the pipelines; and the other ends of the first suction coating channels are communicated with either of the powder bucket or the vacuum dust suction device through a switching device. The powder room disclosed by the invention has the advantages that a powder spraying gun is not needed in the working process; the powder room can be applied to various pipelines with different diameters; and therefore, the spraying cost is effectively reduced and the anticorrosion problem of inner walls of the pipelines is solved.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of metal pipe fittings, in particular to a powder room for suction coating inside pipe fittings. Background technique [0002] The inner wall spraying technology of pipe fittings originated in the United States. It was originally proposed as an anti-corrosion method for the inner wall of pipe fittings. Chemical corrosion will cause great damage to metal pipe fittings. For metal pipe fittings, no matter how good the coating on the outer wall is, how advanced the anti-corrosion process for the outer wall is, such as Failure to carry out anti-corrosion of the inner wall will also cause corrosion and cause the pipe fittings to be scrapped prematurely. At present, the pipe fitting spraying technology used in industry is to use powder spray gun to directly spray anti-corrosion coating on the inner wall of pipe fittings. For smaller pipe fittings, the inner diameter is small, and it is very difficu...

AI Technical Summary

Problems solved by technology

At present, the pipe fitting spraying technology used in industry is to use powder spray gun to directly spray anti-corrosion coating on the inner wall of pipe fittings. For smaller pipe fittings, the inner diameter is smaller, and it is very difficult to use powder spray gun to spray anti-corrosion coating on the inner wall of these pipe fittings.
