Description

Technical Field

[0001] The utility model relates to the technical field of paper machine cleaning, in particular to a spray device for cleaning a dryer net and a dryer net cleaning system. Background Art

[0002] The paper machine is mainly composed of mesh, pressing and drying parts. During the working process, the pulp spread on the mesh and felt is gradually pressed and dried into shape. Therefore, a large amount of pulp fiber often remains on it, which will have an adverse effect on the papermaking process and the quality of the paper sheets. It is easy to contaminate the forming mesh, felt and dry mesh, adhere to the pipes of the paper machine and make it difficult to clean, and be brought into the paper surface and affect the quality of the paper sheets. At the same time, if it is not removed in time, it will shorten the service life of the dry mesh and increase production costs.

[0003] The existing cleaning method uses high-pressure water flow to flush the surface of the dryer net to remove pollutants. This method has a good cleaning effect, but the cleaning nozzle is installed in a single direction, and the water flow only flushes along one angle, making it difficult to fully clean the dryer net. However, due to the complex surface and internal structure of the dryer net, traditional single-angle cleaning usually cannot reach every corner of the dryer net, and cannot clean the dirt deep in the net, resulting in incomplete cleaning and affecting the reuse effect of the dryer net. At the same time, single-direction cleaning has low cleaning efficiency, and it is easy to generate water mist or dirty water splashback during the flushing process, affecting other processes; and due to the splashback of dirty water and the formation of water mist, it is easy to make the nozzle dirty or even blocked, affecting the cleaning efficiency.

[0004] There is no effective solution yet for the problems existing in the related technologies, such as single cleaning direction, low cleaning efficiency, poor cleaning effect, dirty nozzles affecting cleaning efficiency, and dirty water splashing back affecting other processes.
