Powder feeding device for pipeline anticorrosion processing production line

Abstract

The invention discloses a powder feeding device for a pipeline anticorrosion processing production line, and relates to the technical field of pipeline processing. The powder feeding device for the pipeline anticorrosion processing production line comprises a mounting table, wherein a feeding mechanism, a spraying mechanism, a driving mechanism, a drying mechanism, an abutting sliding mechanism and a walking driving mechanism are arranged on the mounting table, and a mounting cylinder is welded to the outer surface of the top of the mounting table. According to the powder feeding device for the pipeline anticorrosion processing production line, it is guaranteed that the spraying mechanism of the device is located in the center of the pipeline, compared with the device with part of a spraying part deviating from the center of a pipeline, the powder feeding device is more uniform in spraying effect; meanwhile, the device can conduct powder feeding spraying operation on the pipelines of different specifications, so that the application range of the device is widened; and the walking driving mechanism can further drive the whole device to walk in the pipeline, and compared with the device adopting a long pipe to extend into the pipeline for spraying, the device is higher in practicability and integrity.

Description

technical field [0001] The invention relates to the technical field of pipeline processing, in particular to a powder feeding device for a pipeline anticorrosion production line. Background technique [0002] Pipeline anticorrosion refers to measures to slow down or prevent pipelines from being corroded and deteriorated under the chemical and electrochemical action of internal and external media or the metabolic activities of microorganisms. Usually, anticorrosion coatings made of epoxy resin powder are used to spray the inner walls of pipelines. way is completed. [0003] At present, most pipeline anti-corrosion powder feeding devices use a special long tube to extend into the inside of the pipeline to spray the inner wall. This type of device occupies a large area. For heavy pipes, the labor input and labor intensity are relatively large, and some devices adopt a trolley-type structural design, which can automatically spray powder on the inner wall of the pipe, but most o...

[0003] At present, most pipeline anti-corrosion powder feeding devices use a special long tube to extend into the inside of the pipeline to spray the inner wall. This type of device occupies a large area. For heavy pipes, the labor input and labor intensity are relatively large, and some devices adopt a trolley-type structural design, which can automatically spray powder on the inner wall of the pipe, but most of these devices are placed directly in the pipe and cannot be used according to The actual specification of the inner wall of the pipeline adjusts the center position of the spraying parts, the distance between the spraying parts and the inner wall of the pipeline is different, the actual spraying is uneven, and the effect is poor
