A rotary flushing unblocking pig

Abstract

The invention relates to a rotary washing blockage relieving pipe cleaning device which comprises a main cylinder body, an assistant cylinder body, a pressure control valve and a rotary washing mechanism, as well as a scraping plate and a leather cup mounted on a main shaft of the pipe cleaning device, wherein the assistant cylinder body is fixed at the front end of the main cylinder body; the pressure control valve is fixedly arranged in an inner chamber at the rear part of the main cylinder body; the rotary washing mechanism is mounted on the assistant cylinder body; the pressure control valve is fixed on the inner wall of the main cylinder body through a supporting plate; the supporting plate adopts a hollow structure; the rotary washing mechanism comprises a rotary washing spray head and a wire brush mechanism; rotating nozzles and horizontal nozzles are arranged on the outer wall of the rotary washing spray head; the inner wall of the rotary washing spray head is connected with a turbine group through a power shaft; the turbine group is mounted in an inner chamber of the assistant cylinder body; the wire brush mechanism consists of a crank sliding block mechanism and wire brush heads. The failure of pipeline blocking caused by hard dirt and more sewage can be effectively removed, and the pipe cleaning device reduces energy consumption, and is economical and practical.

Description

Technical field [0001] The invention relates to a rotary scouring and blocking removal pipe cleaner, which belongs to the technical field of pipeline cleaning machinery. Background technique [0002] After oil and gas pipelines are in operation for a period of time, it is inevitable that a lot of oil, wax, scale, rust and other dirt will be deposited or adhered to the inner wall of the pipeline, which hinders or blocks the normal operation of the pipeline. Usually adopt regular pigging method to solve these problems. The traditional pig is to increase the back pressure through a cup or ball seal, and then rely on the front and back pressure difference to push it forward for cleaning. However, the accumulation of dirt in the pipeline is uneven, and it is easy to form a blockage when the traditional pipe pig encounters a lot of hard dirt. When the pig is jammed, troubleshooting is very troublesome. The usual method is to find the position of the jam, then cut the pipeline, take o...
