Description

Technical Field

[0001] The utility model relates to the technical field related to a cleaning structure of a paper machine, in particular to a switching structure and a cleaning system. Background Art

[0002] The wet section of a paper machine is a key part that determines the quality of paper, among which the forming mesh and felt directly affect the product quality. The mesh holes of the forming mesh and felt are prone to absorb fine fibers, fillers and impurities in the water during long-term operation, affecting the air permeability of the felt and forming mesh, thereby affecting the vacuum degree, which may lead to abnormal production or unqualified products. Therefore, it is extremely important to keep the forming mesh and felt clean for a long time, making the online cleaning machine for the forming mesh and felt a very critical auxiliary equipment.

[0003] Generally speaking, an online cleaning system will be equipped with a main and auxiliary cleaning chamber to store cleaning liquid, so that the main and auxiliary cleaning chambers can be switched during the cleaning process to ensure sufficient cleaning liquid. In addition to controlling the switching valves that switch different cleaning chambers during the switching process, it is also necessary to provide power sources for different cleaning liquids, that is, after the pipeline is switched, the corresponding water pump or centrifugal pump or other delivery source needs to be started to supply the corresponding cleaning liquid into the pipeline for spraying. The cleaning system designed in this way sets the corresponding delivery source according to the required cleaning chamber, and after each switching, it is also necessary to control the corresponding power source to open and close. Therefore, when switching the main and auxiliary cleaning chambers, it is necessary to control the switching valves that switch different cleaning chambers, and it is also necessary to open and close the corresponding delivery source, which makes the switching more cumbersome and the cost of use higher.

[0004] At present, no effective solution has been proposed for the problems in the related art that the switching between the main and auxiliary cleaning chambers is complicated and the cost of use is high. Utility Model Content
