[0023] Specifically, the outer surface of the fixing frame 1 is fixedly connected to the connecting frame 3 and the sealing gasket 2 , respectively, and the bottom surface of the sealing gasket 2 is fixedly connected to the upper surface of the connecting frame 3 .

[0024] Through the above technical solution, by providing the connecting frame 3, it can be connected to the equipment, so that the fixing frame 1 can be fixed conveniently, and the sealing gasket 2 can be used to improve the sealing performance after fixing.

[0025] Specifically, two groups of fixing pins 4 are arranged below the connecting frame 3 , and the top end of each fixing pin 4 passes through the connecting frame 3 and the sealing gasket 2 in sequence and extends to the top of the sealing gasket 2 .

[0026] Through the above technical solution, by providing the fixing pin shaft 4, the connecting frame 3 can be penetrated and fixed in the equipment, so that the fixing frame 1 can be used stably.

[0027] Specifically, the outer surface of each sliding groove frame 11 is fixedly connected to the reinforcement frame 8 , and the side surfaces of each group of reinforcement frames 8 that are away from each other are fixedly connected to the inner wall of the filter plate 7 .

[0028] Through the above technical solution, by providing the reinforcement frame 8, the sliding groove frame 11 can be reinforced on the filter plate 7, so that the sliding groove frame 11 can be used stably.

[0029] Specifically, the outer surface of each connecting rod 13 is fixedly connected with a fixing ring 12 , and the side surfaces of each group of fixing rings 12 that are away from each other are fixedly connected with the side surfaces of each group of limiting blocks 6 that are close to each other.
