Airbag type decomposable water pressure spin thorn column pig

Abstract

The invention discloses an airbag type stab columnar pipe cleaner capable of dissolving water pressure and automatically rotating. The airbag type stab columnar pipe cleaner comprises a column body, wherein the column body is provided with a conical head part; three groups of rotary flow guiding plates are arranged on the outer wall of the column body and are equidistantly distributed along the circumferential direction of the column body at intervals; a pressure-proof airbag is arranged in an inner cavity of the column body; steel brushes are arranged on the flow guiding plates; each steel brush comprises a plurality of groups of comb teeth which are arranged in parallel; the comb teeth are firmly embedded in the flow guiding plates by steel nails or adhered to the flow guiding plates by steel wires; the flow guiding plates are fixed with the column body in an embedded way; the pressure-proof airbag adopts a sealed structure; the range of external pressure borne by the pressure-proof airbag is 0.6-1.0MPa; the column body is made of a high-strength polyurethane foam material; a polyurethane elastic material coating layer is paved on the surface of the column body. According to the airbag type columnar pipe cleaner disclosed by the invention, automatic rotation forwarding and steel brush cleaning of the pipe cleaner in a pipe through water flow pressure are realized, the pipe cleaner is enabled to successfully pass through a blocking point by an airbag type structure, higher hardness and higher strength are ensured by a steel nail type steel brush, and efficient cleaning on long, short and complicated pipelines can be realized.

Description

technical field [0001] The invention relates to the field of pipeline cleaning, in particular to an airbag-type decomposable hydraulic spin thorn-type pipeline pig. Background technique [0002] The pig is a special tool for pipeline cleaning driven by gas, liquid or pipeline conveying medium. The pig cleaning technology can remove scale in the pipe, increase the displacement of the pipeline, improve the efficiency of the system, and save a lot of energy. [0003] The pipelines that transport fluids such as oil, water, and gas for a long time will be blocked, and the pipelines need to be cleaned and dredged. Pipeline cleaning technology includes high-pressure water jet cleaning technology, ultrasonic cleaning technology, dry ice cleaning technology, laser cleaning technology, plasma cleaning technology, electrolytic cleaning technology, etc. Mechanical cleaning is widely used as a cleaning method with low cleaning cost and relatively simple equipment manufacturing.

AI Technical Summary

Problems solved by technology

[0004] In the existing pigging technology, short pipelines are generally cleaned by high-pressure water jet method or chemical method. High-pressure water jet method requires specific construction equipment, and can only clean short-length pipelines, and is not suitable for some specific construction situations , such as coal mines, etc.; the chemical cleaning method requires a large amount of chemical agents, and the cleaning effect is unstable. At the same time, a large amount of chemical wastewater generated by the cleaning needs to be treated, which pollutes the environment, is labor-intensive, and corrodes the equipment and pipelines.

Long pipelines generally use mechanical straight-type pigs, which have poor cleaning effect and high running resistance, which is prone to jamming
