Pipeline inner wall dredging device

Abstract

The invention discloses a pipeline inner wall dredging device, and discloses a dredging device which is suitable for small-caliber pipelines, can be used for scraping and cleaning pipe walls by makingexpansion elastic pieces attached to the pipe walls and rotate and cooperates with high-pressure gas and cleaning liquid to conduct high-pressure flushing on the pipelines. The dredging device is characterized in that an inner gas pipe is arranged in a main body pipe, the two ends of the inner gas pipe penetrate out from the inside of the main body pipe respectively, a threaded pipe is connectedwith the bottom end of the inner gas pipe, a lead-in head is placed on the threaded pipe, a mounting sleeve is arranged in the middle of the top of the lead-in head, the mounting sleeve is in threadedconnection with the threaded pipe, the lead-in head is of a conical structure, the tip of the lead-in head is downward, a plurality of mounting tables are arranged on the outer side face of the bottom end of the main body pipe at equal angles, a plurality of mounting grooves are formed in the outer side face of the lead-in head at equal angles, one ends of the expansion elastic pieces are correspondingly arranged on the mounting tables one to one through connecting shafts, and the other ends of the expansion elastic pieces are correspondingly arranged in the mounting grooves one to one and connected with the lead-in head through connecting shafts.

Description

technical field [0001] The invention relates to a dredge for the inner wall of a pipeline, relates to a dredge for cleaning attachments on the inner wall of a pipeline, and belongs to the field of industrial equipment. In particular, it relates to a dredger suitable for small-diameter pipelines, which scrapes and cleans the pipe walls through the expanded expansion shrapnel attached to the pipe wall and rotates, and at the same time cooperates with high-pressure gas and cleaning liquid to perform high-pressure flushing in the pipe. Background technique [0002] At present, in industrial production, pipelines are usually used to transport liquids, and it is easy to form attachments on the inner walls of the pipelines. The most common ones are scales on the inner walls of water pipes, which seriously affect the transmission of liquids, serious pipeline blockages, and excessive local pressure. , causing the pipeline to burst, and some viscous liquids are easy to adhere to the i...

Its device cannot be cleaned, especially foreign matter attached to the inner wall

[0004] Publication number CN204456339U discloses a sewer pipe dredger, which includes: electric drill, the bottom of the electric drill is fixedly connected with a handle, the handle has a switch, one end of the electric drill is fixedly connected with a pipeline dredging flexible shaft, and the other end of the pipeline dredging flexible shaft is fixed A camera is connected, and the camera is a waterproof camera. An external water nozzle is installed on the periphery of the camera. The water nozzle and the camera are located in the inner cavity of the pipe dredging flexible shaft. The other end of the water nozzle is connected to the faucet, the water nozzle and the faucet. They are connected by a hose, the hose is located in the inner cavity of the pipeline dredging flexible shaft, and the outer wall of the pipeline dredging flexible shaft is fixedly connected with a cleaning claw, which corresponds to the position of the water nozzle and the camera. Drive the flexible shaft to rotate, but the internal attachments still cannot be cleaned

[0005] Publication number CN106623290A discloses a pipeline cleaning mechanism, which includes a driving mechanism. The output end of the driving mechanism is provided with a rotating mechanism. The output end of the rotating mechanism is provided with a cleaning mechanism. The cleaning mechanism includes several cleaning units arranged in sequence. On the same line, the cleaning unit includes a fixed block, and the outside of the fixed block is provided with a cleaning brush. This device cleans through a single mechanical method. When there are many attachments inside the pipe, it is easy to get stuck
