Description

Technical Field

[0001] The utility model belongs to the technical field of anti-corrosion pipeline production, and in particular relates to an electrostatic spraying device for anti-corrosion paint for anti-corrosion pipelines. Background Art

[0002] When metal pipes are in use, they are often affected by the use environment. The surface of the pipes will be corroded due to the influence of humidity, acid and alkali. This corrosion will greatly reduce the service life of the metal pipes. Therefore, it is necessary to take effective protective measures to slow down the corrosion of metal pipes. The existing commonly used anti-corrosion means is to use anti-corrosion coating spraying. The existing spraying process uses a spray gun. The staff sprays the anti-corrosion coating on the surface of the pipe with a spray gun. This not only has low spraying efficiency, but also requires the use of support frames of different heights when spraying pipes of different diameters. It is also necessary to constantly move the support frame and spraying equipment to spray the pipe surface in all directions. The staff will work for a long time, which will cause certain damage to their health. Therefore, in the prior art, the anti-corrosion coating is sprayed on the pipe manually. First, the efficiency is low and affects the health of the staff. Secondly, according to the pipes of different diameters, it is necessary to frequently replace the pipe support frame and move the workers' construction scaffolding, which is inconvenient for construction.
