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 pipe cleaning device for rotary flushing and blocking removal, and belongs to the technical field of pipe cleaning machinery. Background technique [0002] After the oil and gas pipelines have been in operation for a period of time, it is inevitable that a lot of dirt such as oil, wax, scale and rust will be deposited or adhered on the inner wall of the pipeline, hindering or blocking the normal operation of the pipeline. These problems are usually addressed by periodic pigging. The traditional pig is sealed by a cup or a ball to increase the back pressure, and then relies on the pressure difference between the front and rear to push it forward for pigging. However, the accumulation of dirt in the pipeline is uneven, and when the traditional pig encounters a lot of hard dirt, it is easy to form a jam. When the pig is stuck, troubleshooting is very troublesome. The usual method is to find the location of the blockage, then c...
