A locking structure is formed between the positioning hole 18 and the positioning pin 19. When the sieve plate 5 needs to be cleaned, the fixing pin 23 is removed from the fixing plate 21 and the connecting plate 22. After the cleaning of the sieve plate 5 is completed, the sieve plate 5 can be easily removed from the inside of the screening chamber 1, so that the sieve plate 5 can be easily removed from the inside of the screening chamber 1.

[0021] The power mechanism includes a telescopic cylinder 7, a movable block 8, a fixed sleeve 9, a movable rod 10, a roller 11, a return spring 12, an installation cavity 16 and a limiting structure. The installation cavity 16 is installed at the top of the screening cavity 1, and the telescopic cylinder 7 is installed on one side of the installation cavity 16. One end of the telescopic cylinder 7 extends to the interior of the installation cavity 16, and the movable block 8 is installed at one end of the telescopic cylinder 7.

The polymer polyether that passes through the screen falls from the screen plate 5 to the bottom of the screening chamber 1 and is discharged through the discharge port 4, and the polymer that does not pass through the screen falls from the screen plate 5 to the bottom of the screening chamber 1 and is discharged through the discharge port 4. The high molecular polyether that has passed through rolls out from both sides of the sieve plate 5.
