The crushing knife 4 is fixedly installed on the shaft sleeve 11 in the filter screen 5. The crushing knife 4 is a double-blade or multi-blade quenched crushing knife with two or more blades, so that the spin-dry filter cylinder 3 and the crushing knife 4 can be driven to rotate synchronously by the driving motor. The material entering the crushing cylinder body 1 can be crushed by the rotating crushing knife. The crushed material is discharged from the filter screen 5 and separated from the slurry by the rotation of the spin-dry filter cylinder 3.

[0026] Further, the filter screen 5 includes an annular sleeve 9, a bottom disc 10 provided at the bottom of the annular sleeve and having sieve holes 35, and a central hole provided at the center of the bottom disc. The central hole is installed with a freely rotating shaft sleeve 11. The sieve holes 21 have a diameter of 0.5-20 mm. The shaft sleeve 11 penetrates the upper and lower surfaces of the bottom disc 10. The crushing knife 4 is installed in the annular sleeve and fixedly installed on the shaft sleeve 11 (the upper half of the shaft sleeve, and the outer circumferential surface of the shaft sleeve is provided with an annular groove in which an elastic ring 36 for positioning and installing the crushing knife is installed).
