Description

Technical Field

[0001] This invention relates to the field of internal cavity cleaning technology, specifically to a square tube internal cavity cleaning device and its usage method. Background Technology

[0002] Currently, the cleaning of the inner cavity of tubular components is mostly done by manually cleaning the oil or impurities on the inner wall of the tubular component, and then rinsing the inner cavity with a cleaning machine. This method is sufficient for straight pipes, but for complex curved pipes and three-dimensional space pipes, manual cleaning can only clean the ends of the tubular components.

[0003] For example, Chinese Patent Publication No. CN209006316U discloses the following technical solution: a cleaning device for the inner cavity of a fixed tube sheet heat exchanger, belonging to the field of heat exchanger technology. The cleaning device includes a cleaning pipe and a scraper assembly. The outer peripheral wall of the cleaning pipe is provided with bristles, and the cleaning pipe has an accommodating space extending axially along the cleaning pipe. An opening penetrating to the outer peripheral wall of the cleaning pipe is also provided on the cleaning pipe. The scraper assembly includes an eccentric rod eccentrically disposed within the accommodating space along the axial direction of the cleaning pipe, and the eccentric rod is rotatably connected to the cleaning pipe. A scraper extending radially along the eccentric rod is installed on the eccentric rod. The scraper has a closed state when rotating with the eccentric rod into the accommodating space, and an open state when rotating with the eccentric rod to pass through the opening and extend out of the cleaning pipe. When the scraper is in the open state, the scraper extends beyond the bristles. The cleaning device for the inner cavity of a fixed tube sheet heat exchanger provided by this utility model can remove stubborn dirt inside the tube bundle and improve the cleanliness of the tube bundle.

[0004] The existing technology has the following problems:

[0005] Oil stains or impurities adhering to the inner wall of the tubular components are difficult to clean, and even rinsing with a cleaning machine is not enough to remove them. This results in inadequate cleaning of the inner cavity of some bends and three-dimensional space tubes, failing to meet the cleanliness requirements. Therefore, improvements are being made.
