The two synchronous pulleys 24 are connected by a synchronous belt 25 sleeved on their outer sides. The drive motor 23 drives the filter assembly 3 to rotate as a whole through the synchronous pulleys 24 and the synchronous belt 25, generating centrifugal force to assist filtration.

[0032] Both ends of the outer wall of the separator 321 are provided with through grooves 323, allowing waste liquid to come into contact with the filter screen 326 through the through grooves 323. A U-shaped bracket 324 is fixedly connected to the outer wall of the separator 321 and to the outer position of the through grooves 323.

The drive motor 23 is started, and the output shaft of the drive motor 23 drives one synchronous wheel 24 to rotate. The synchronous wheel 24 drives another synchronous wheel 24 to rotate through the synchronous belt 25, thereby making the guide pipe 31 and the filter separation cylinder assembly 32 rotate at high speed. Under the action of centrifugal force, the NMP waste liquid moves towards the outer wall of the separation cylinder body 321, and comes into contact with the filter screen 326 through the through groove 323. The impurities in the waste liquid are intercepted by the filter screen 326, and the filtered waste liquid enters the guide cylinder 11 and is finally discharged from the drain port 13.
