As shown in fig. 2-3, 2 material inlets 211 are formed on the upper edge of the feeding filter plate 21. The cavity between the feed filter plate 21 and the membrane 22 forms a material zone 214 (the membrane is not shown). A material area 214 is provided on each side of the feed filter plate 21.
As shown in fig. 2-5, an independent material channel 212 is provided between the material area 214 and the material inlet 211 on each side, the material channel 212 is arc-shaped, and the material to be dehydrated enters the material area 214 through the material channel 212. Each material inlet 211 is provided with 2 rows of material channels 212, each row is provided with 3 material channels 212, and the 2 rows of material channels 212 respectively correspond to the material areas 214 on the two sides of the feeding filter plate 21.
As shown in fig. 3-5, two filter cloth fixing grooves 213 are formed in the feeding filter plate 21, and sealing rubber strips are embedded in the filter cloth fixing grooves 213 to fix the filter cloth 30. The space between the adjacent filter cloth fixing grooves 213 covered by the filter cloth 30 forms a buffer space 40, and since the two sides of the second filter cloth fixing groove 213 are covered by the filter cloth 30, the pressure on the two sides of the second filter cloth fixing groove 213 is basically kept equal, and it is difficult for enough pressure difference in the buffer space 40 to press muddy water in the buffer space 40 through the second filter cloth fixing groove 213, thereby reducing the possibility that the sludge penetrates through the filter cloth.
