Natural gas pipeline cleaning device capable of automatically cleaning waste residues

Abstract

The natural gas pipeline cleaning device capable of automatically cleaning the waste residues comprises a steel framework, a positioner is arranged in the steel framework, leather cup mechanisms are arranged on the two sides of the steel framework, a first inner cavity is formed in a leather cup main body, a sliding rod and a spring are arranged between a bracket and a limiting block, and the sliding rod and the spring are arranged in the steel framework. The ends, away from the bracket, of the sliding rods extend into sliding grooves formed in the limiting blocks, a slag removal mechanism is arranged on one side of the steel framework, and a dehumidification mechanism is arranged on the other side of the steel framework. According to the natural gas pipeline cleaning device capable of automatically cleaning the waste residues, the residue cleaning cutter and the flexible brush are arranged, the motor drives the top plate to rotate so as to drive the residue cleaning cutter and the flexible brush to rotate, and the residue cleaning cutter can conveniently scrape away the firm waste residues attached to the inner wall of the natural gas pipeline; the loose disintegrating slag close to the pipe wall can be brushed away through the flexible brush, and the slag removing cutter and the flexible brush work together, so that the waste slag is removed more thoroughly, and the pipe wall is not damaged.

Description

technical field [0001] The invention relates to the technical field of natural gas pipelines, in particular to a pigging device for natural gas pipelines for automatically cleaning waste residues. Background technique [0002] In the process of natural gas transportation, the accumulation of impurities such as liquid and waste residue will reduce the pipeline flow area and reduce the efficiency of natural gas transmission. The condensate precipitated in the pipeline will react with hydrogen sulfide and carbon dioxide in the natural gas and corrode the inner wall of the pipeline. Pigging operations are carried out regularly to reduce pipeline corrosion and improve transmission efficiency. The pig is driven by gas, liquid or pipeline transmission medium. It is a special tool for cleaning the pipeline. Generally, the pig has a rubber pig ball and a leather bowl. There are six series of pipe cleaners, straight pipe pigs, wax-scraping pipe pigs, foam pipe pigs, and buckling detec...

Problems solved by technology

[0004] The purpose of the present invention is to provide a pigging device for natural gas pipelines that automatically cleans waste residues to solve the problem that cleaning waste residues may not be thorough and the mucus in natural gas pipelines is not easy to remove. It may not be easy to rebound, causing the problem that all the falling debris cannot be pushed out after cleaning
