Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a mesh self-cleaning device. Background Art

[0002] The raw material of paper is usually tree fiber, but with the shortage of resources, the cost of obtaining tree fiber is relatively high. Therefore, some paper mills recycle waste cardboard to make paper to save resources. The recycling of waste paper requires firstly to crush the waste paper raw material through a pulping machine, and then to coarsely screen the waste paper pulp through a coarse screening device to separate the coarse impurities in the waste paper pulp, and then to make the filtered slurry adhere to the mesh to remove most of the water in the slurry. The dehydrated slurry forms a paper fiber layer on the mesh, and then the fiber layer is dried to form paper.

[0003] After the mesh has been used for a period of time, the paper fibers remaining on the mesh need to be removed. In the related art, the method of removing the fibers attached to the surface of the mesh is usually to set a spray device above the mesh and a liquid collection tank below the mesh. The spray device sprays water for cleaning on the upper surface of the mesh, so that the fibers on the mesh pass through the mesh and fall into the liquid collection tank. However, in actual application, paper fibers are easy to remain on the surface of the mesh and are not easy to remove by spraying. Utility Model Content
