Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a cleaning device for the inner wall of heating pipelines. Background Technology

[0002] As we all know, heating pipes are devices that transport hot water from municipal heating plants to users' homes to provide indoor heating. After prolonged use, the inner walls of heating pipes are prone to accumulating scale, which can easily cause pipe cracks and damage. To avoid this, it is necessary to clean and maintain the inner walls of the pipes regularly.

[0003] Currently, the general method for descaling is to add descaling agents to heating pipes, but this method takes a long time and has poor descaling effect. A search of related technologies reveals that a utility model patent with publication number CN215114171U discloses a slag removal device for heating pipes. This device includes a slag removal body with a device groove at its right end. A driver is fixedly connected to the middle of the left end of the slag removal body. The output end of the driver passes through the slag removal body and is fixedly connected to a rotating structure. The left side of the rotating structure is located within the device groove, and a protective cone is fixedly connected to the right end of the rotating structure. Spiral slag removal teeth and a cleaning structure are fixedly connected to the right side of the outer surface of the rotating structure, with the spiral slag removal teeth and cleaning structure distributed alternately.

[0004] While the aforementioned technologies have increased the efficiency and speed of slag removal operations, improved the flexibility and stability of slag removal equipment, and avoided slag removal jams or low slag removal efficiency, the applicant has found that after being put into use, they are difficult to adapt to the cleaning of pipe walls with various inner diameters, and have certain limitations in use.

[0005] Therefore, we propose a cleaning device for the inner wall of heating pipes. Utility Model Content
