Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, specifically to a disc-type cutting low-pressure cleaning machine. Background Technology

[0002] Currently, the dredging, cleaning, and pre-treatment of municipal sewer pipes are gradually becoming more mechanized. However, my country's mechanical dredging and cleaning of sewer pipes mainly relies on advanced foreign technologies. The use of some high-tech cleaning products has given us a new understanding of sewer pipe dredging and cleaning, but most cleaning equipment still depends on imported products, which keeps our cleaning costs high. Moreover, foreign products are not necessarily suitable for dredging sewer pipes in my country.

[0003] Therefore, we need to develop a disc-type low-pressure cleaning machine for unclogging sewer pipes in my country.

[0004] Chinese patent CN211114049U discloses a low-pressure cleaning and cutting nozzle, comprising a primary shaft, a rotating sleeve, and multiple connecting pipes. The primary shaft has a primary flow channel and multiple primary side holes on its sidewall. The rotating sleeve is fitted over the primary shaft and has multiple secondary side holes on its sidewall. One side opening of each connecting pipe connects to one of the secondary side holes, and the other side opening connects to a nozzle. The primary flow channel, primary side holes, secondary side holes, connecting pipes, and nozzle are all interconnected. The nozzle's spray direction is tangential to the primary shaft. The rotating sleeve connects to a reamer and a chain. The flow block connects to a support. In this patented product, the support contacts the inner wall of the pipe during use, resulting in uneven movement. The support's internal design is unreasonable; during retraction, the pointed end of the support is easily obstructed. The cutting section uses a chain, which can only be separated from the connecting pipes, requiring individual replacement, making the operation cumbersome. Utility Model Content
