Description

Technical Field

[0001] The utility model relates to the technical field related to papermaking machines, and in particular to a cleaning structure and system for a forming net of a papermaking machine. Background Art

[0002] In the papermaking process, wet paper is carried by the forming net to multiple drying places for gradual drying. The dried paper is separated from the forming net, and the forming net needs to be circulated to carry new wet paper. After the forming net is separated from the paper, some debris and adhesives and other dirt will remain on the forming net. If these dirt are not cleaned up in time and effectively, it will affect the quality and production efficiency of the paper and increase production energy consumption. In the prior art, there is a method of regularly scraping the dirt on the forming net by a diamond scraper, but due to the mechanical forced scraping off the surface of the dry net, the wear on the dry net is large, which affects the life of the dry net; another method is to flush with water, which often uses multiple nozzles to flush the forming net in an all-round manner. This method is easy to produce a large amount of water mist during the flushing process, and the water mist splashes and gathers and drips on the cleaning head, thereby affecting the cleaning environment.

[0003] At present, no effective solution has been proposed for the problem in the related art that water mist splashes, gathers, and drips on the cleaning head, affecting the cleaning environment. Utility Model Content
