A spraying device for anti-corrosion coating on the outer layer of chemical pipelines

Abstract

The invention discloses a spraying device for anti-corrosion coating on the outer layer of chemical pipelines, which can flexibly adjust the distance between the first support plate and the second support plate according to the length of the pipeline to be sprayed with anti-corrosion coating, thereby improving the ability of the spraying device to spray the pipeline It can evenly and effectively spray paint on the pipeline; through the cooperation of the telescopic bellows and the drying device, it can not only effectively protect the pipeline, but also quickly and effectively heat the paint on the surface of the pipeline to accelerate the curing of the paint , and there is no need to transfer the pipeline to the drying room for the second time, avoiding the collision and scratching of the pipeline coated with paint during the second transfer to the drying room, ensuring the integrity of the anti-corrosion coating layer on the outer surface of the pipeline, and improving the anti-corrosion coating layer of the pipeline Spraying processing efficiency; the spraying device of the present invention has a simple and reasonable structural design, high feasibility of preparation and implementation, and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of pipeline spraying equipment, and in particular relates to a spraying device for anticorrosion coating on the outer layer of chemical pipelines. Background technique [0002] Chemical pipelines refer to pipelines used in the chemical industry, and steel-plastic chemical pipelines are the main types of pipelines used. They are mainly composed of ultra-high molecular weight polyethylene (UHMW-PE), which has excellent comprehensive performance, wear resistance, low temperature resistance, and Corrosion, self-lubrication, and impact resistance are the highest among all plastics, and the wear resistance is better than that of polytetrafluoroethylene, nylon, carbon steel and other materials. It can work under the temperature condition of -269℃~80℃ for a long time. [0003] Before chemical pipelines are produced and put into use, it is generally necessary to spray anti-corrosion coatings on the outer surface of c...

Problems solved by technology

The traditional method of spraying anti-corrosion coatings for pipelines is generally spraying with manual hand-held spray guns. Since the pipeline is generally cylindrical, it is necessary to rotate the pipeline at any time during spraying. Whether the paint is sprayed uniformly will not ensure the quality of the paint spraying. At the same time, after spraying, the pipeline needs to be transferred to the drying room for drying and finalizing the paint. The secondary transfer process is cumbersome, and it is easy to damage the pipeline Causes collision and scratches, which in turn leads to loss of paint and damage to pipes, which is not conducive to production
