[0033] Specifically, during filtration, firstly, a filter cloth is wrapped around the outside of the filter plate body 1, and the material passes through the feed port 12, the feed channel 14 and the concave cavity 11 in sequence. Under the filtering action of the filter cloth, the solid impurities in the material are blocked in the filter chamber of the adjacent filter plate body 1, and the water in the material passes through the filter cloth and flows out from the plurality of water outlets 13, thereby completing the filtration; wherein, the filter plate body 1 is used to carry the concave cavity 11, the feed port 12 and the plurality of water outlets 13, etc.; the concave cavity 11 is used to communicate with the concave cavity 11 of the adjacent filter plate body 1 to form a filtration The filter chamber is convenient for materials to pass through, and under the action of the filter cloth, solid impurities in the materials are blocked in the filter chamber; the feed port 12 is convenient for materials to enter; a plurality of water outlets 13 are convenient for water in the materials to flow out, and the specific number of the water outlets 13 is not limited, and can be three, four, etc., preferably four, and the four water outlets 13 are respectively located at the four corners of the filter plate body 1; the support assembly 2 includes a plurality of support blocks 21, one end of the support block 21 is connected to the filter plate body 1, and the other end of the support block 21 is connected to the adjacent filter plate body 1 The support block 21 conflicts with the support block 21. Since the support blocks 21 are circumferentially arranged around the feed port 12, it is convenient to ensure good support performance at the feed port 12, prevent the filter chamber at the feed port 12 from being squeezed and reduced in volume, thereby preventing the feed port 12 from being blocked. At the same time, the other end of the support block 21 and the support block 21 of the adjacent filter plate body 1 are in conflict through two layers of filter cloth (one layer of filter cloth is connected to the filter plate body 1, and the other layer of filter cloth is connected to the adjacent filter plate body 1), so that the support block 21 also plays the role of a cloth clamp to ensure the installation stability of the filter cloth. Among them, the connection method between the support blocks 21 and the filter plate body 1 is preferably an integrally formed connection, so that the filter plate of the present application can play the role of a cloth clamp when installing the filter cloth without the need to additionally install a cloth clamp.
