When the locking rod 7 is twisted outward for a certain distance, the clamping block 6 can be rotated along the locking rod 7 to leave the filter cotton, and the filter cotton can be removed.

[0033] Working principle: First, place the filter cotton into the filter cotton placement groove 5 of the first pressure plate 2 and the middle pressure plate 3 on the plate and frame filter press body 1, and then pass the locking rod 7 through the positioning hole 11 on the pressing block 6, and then fix it into the fixing hole 8 on the first pressure plate 2 and the middle pressure plate 3, tighten the locking rod 7, and fix the position of the pressing block 6 by fixing the position of the locking rod 7. The anti-wear pad 10 can prevent the mutual wear between the pressing block 6, the locking rod 7 and the filter cotton, and the pressing block 6 can just hold the filter cotton The filter cotton is compacted in the filter cotton placement groove 5 to prevent the filter cotton from falling off along with the filter block during mud removal. When the mud pressing work is carried out, the large ends of the pressing block 6 and the locking rod 7 can be just engaged in the positioning groove 9, and will not interfere with the mud pressing work between the first pressing plate 2, the middle pressing plate 3 and the final pressing plate 4. When the filter cotton needs to be replaced, it is only necessary to twist the locking rod 7 outward for a certain distance to make the pressing block 6 rotate horizontally along the locking rod 7. The pressing block 6 will leave the filter cotton, so that the filter cotton can be removed.
