Specifically, in this embodiment, the anti-falling-off element 645 is sleeved outside the guide rod 644, and the anti-falling-off element 645 is screwed with the guide rod 644; in the process of filter pressing different materials, the distance between the high-pressure diaphragm plate 31 and the high-pressure filter plate is different, so that the distance between the two filter cloths 32 after being unfolded is different, and the sliding distance of the cloth hanging plate 643 on the guide rod 644 needs to be adjusted; the separation preventing member 645 is screwed to the outside of the guide rod 644, and the position of the separation preventing member 645 on the guide rod 644 can be adjusted by rotating the separation preventing member 645, so that the sliding distance of the cloth holding plate 643 on the guide rod 644 is adjusted according to the change of the filter plate spreading distance.
Specifically, in this embodiment, a chain plate 66 is disposed between two ends of two adjacent cloth hanging pieces 64; two ends of the cloth hanging piece 64 closest to the support 63 are respectively provided with a chain plate 66 connected with the support 63; specifically, the end of the cloth hanging plate 643 is fixedly connected with the connecting rod 65 connected with the chain plate 66.
The two connecting rods 65 at the same end of the two cloth hanging plates 643 at the side where the two cloth hanging pieces 64 are close to each other are respectively inserted into the two long holes 661 of the same chain plate 66, and the connecting rod 65 on the support 63 and the connecting rod 65 at the end of the cloth hanging plate 643 closest to the support 63 are simultaneously inserted into the two long holes 661 of the same chain plate 66.
