Pipeline inner wall rust removal device capable of collecting scrap iron

Abstract

A pipeline inner wall rust removal device capable of collecting scrap iron comprises a driving trolley and a polishing part. The driving trolley is arranged inside a pipeline and used for travelling,and the polishing part is used for conducting polishing rust removal on the inner wall of the pipeline. The output end of the driving trolley is connected with a hollow rotating roller in a rotating mode, and the polishing part sleeves the outer wall of the hollow rotating roller. The output end of the driving trolley is connected with the hollow rotating roller in a rotating mode, the polishing part sleeves the outer wall of the hollow rotating roller, scrap iron collecting holes which pass through the hollow rotating roller are formed between gaps formed by a spiral polishing brush, the falling scrap iron of the polishing part in the polishing process can pass through the scrap iron collecting holes between the gaps formed by the polishing brush, enter the hollow rotating roller and enter a material collecting box under the action of guide strips to be collected, and therefore the work of collecting the scrap iron is accomplished in the polishing process, the scrap iron does not needto be manually disposed again, the degree of automation of the whole process is high, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of pipeline derusting treatment, in particular to a pipeline inner wall derusting device capable of collecting iron filings. Background technique [0002] Large-diameter pipelines are widely used, especially in the fields of crude oil and natural gas transportation and sewage removal. Large-diameter pipes have long lengths and large inner diameters. Before installation of steel pipes conveying corrosive media, the inner wall needs to be treated with anti-corrosion treatment. Before the anti-corrosion coating is painted, the inner wall of the pipe must be derusted according to the design and specification requirements. The current derusting method is that workers enter the pipeline with a hand-held polishing machine for derusting and grinding. This method is time-consuming, laborious, inefficient, and dangerous during operation, and the removed rust will endanger the health of workers. [0003] The Chinese invention w...

Problems solved by technology

Large-diameter pipes have long lengths and large inner diameters. Before installation of steel pipes conveying corrosive media, the inner wall needs to be treated with anti-corrosion treatment. Before the anti-corrosion coating is painted, the inner wall of the pipe must be derusted according to the design and specification requirements. The most common rust removal method is for workers to enter the pipeline with a hand-held polishing machine for rust removal and grinding. This method is time-consuming, laborious, inefficient, and dangerous during operation, and the removed rust will endanger the health of workers.

[0003] The Chinese invention with the publication number CN206325908U discloses a large-diameter pipe inner wall derusting device, but the device cannot collect the removed iron filings while derusting, so manual re-collection is required, and automatic derusting cannot be fully realized. rust process
