[0020] The inner wall of the plate body 1 is fixedly connected with two wear-resistant high-resilient rubber strips 3 , which are respectively surrounded between the inner side surfaces of the two wear-resistant coarse fiber filter layers 2 and the edges of the inner wall of the plate body 1 .

[0021] Two water pumping pipes 4 are arranged at the bottom of the plate body 1 , the top ends of the two water pumping pipes 4 are connected to the inner cavity of the filter cavity 5 , the bottom ends of the water pumping pipes 4 are provided with a sealing structure for connection, and the surface of the plate body 1 is provided with a connection structure for installation.

[0022] Highly wear-resistant coarse fibers are woven and formed at high temperature to form a wear-resistant coarse fiber filter layer 2 with controllable air permeability. The wear-resistant coarse fiber filter layer 2 is used for filtration. The surface of the wear-resistant coarse fiber filter layer 2 is smooth, and fine particles are not easy to enter the filter medium to cause blockage, thereby maintaining stable air permeability during long-term work. Wear-resistant high-rebound rubber strips 3 are arranged around the wear-resistant coarse fiber filter layer 2, and the installation consistency is good.

[0023] The wear-resistant coarse fiber filter layer 2 and the wear-resistant high-resilient rubber strips 3 around it are formed in one step by molding. The wear-resistant high-resilient rubber strips 3 prevent the wear-resistant coarse fiber filter layer 2 from expanding and contracting during operation, thereby avoiding the poor ductility of the wear-resistant coarse fiber filter layer 2, increasing the service life of the wear-resistant coarse fiber filter layer 2, and improving the stability of the wear-resistant coarse fiber filter layer 2 during filtering use.

[0024] The wear-resistant coarse fiber filter layer 2 is not blocked and does not require acid washing, which plays a role in energy saving and consumption reduction. The acid-free backwashing of the filter plate does not require acid substances, which reduces acid pollution to the water environment and improves the operational safety of the working area.

[0025] Furthermore, the sealing structure includes a rubber sleeve 14 , which is sleeved on the bottom end of the outer surface of the water pumping pipe 4 , and a locking structure is provided on the surface of the rubber sleeve 14 .

[0028] In this embodiment, after removing the nut 12, the bolt 10 is taken out from the through opening, and the first semicircular plate 8 and the second semicircular plate 11 can be removed, which is convenient for releasing the lock of the rubber sleeve 14 and removing the rubber sleeve 14 from the surface of the water suction pipe 4.

[0029] Furthermore, an anti-loosening gasket 13 is provided between the top of the nut 12 and the bottom of the bottom connecting ear 9 .

[0030] In this embodiment, the anti-loosening gasket 13 improves the anti-loosening property of the nut 12 and improves the stability during the connection between the first semicircular plate 8 and the second semicircular plate 11.

[0031] Furthermore, the connection structure includes two mounting blocks 6 , which are respectively fixedly connected to two ends of the bottom of the front side of the plate body 1 , and the surfaces of the mounting blocks 6 are provided with mounting holes 7 that penetrate the plate body 1 .

[0032] In this embodiment, the mounting block 6 and the mounting hole 7 facilitate the connection and fixation between the plate body 1 and the filter, and facilitate the installation and use of the plate body 1.

The surface of the wear-resistant coarse fiber filter layer 2 is smooth, and fine particles are not easy to enter the interior of the filter medium to cause blockage, thereby maintaining stable air permeability during long-term work. The wear-resistant coarse fiber filter layer 2 is provided with wear-resistant high-rebound rubber strips 3 around it, and the installation consistency is good. The wear-resistant high-rebound rubber strips 3 prevent the wear-resistant coarse fiber filter layer 2 from expanding and contracting during the working process, avoiding the situation where the wear-resistant coarse fiber filter layer 2 has poor ductility, thereby improving the service life of the wear-resistant coarse fiber filter layer 2, and improving the stability of the wear-resistant coarse fiber filter layer 2 during filtering.
