The filter screen 53 is fixedly installed in the mesh frame 52, and the striking pile 54 is fixedly connected to the upper end side wall of the connecting seat 55, and a plurality of striking piles 54 are provided. The connecting seat 55 is connected to the driving mechanism 7. After the debris falls onto the connecting seat 55, the driving mechanism 7 drives the connecting seat 55 to drive the striking pile 54 to rotate at high speed, thereby crushing and stirring the debris. The connecting seat 55 drives the mesh frame 52 and the filter screen 53 to rotate at high speed, so that the filter screen 53 drives the debris to rotate, and the centrifugal force is used to drive the debris to slide upward along the filter screen 53. At the same time, the centrifugal force is used to separate and screen out the muddy water in the debris through the filter screen 53. The annular protective plate 51 is used to block the gap between the water retaining shell 41 and the mesh frame 52 to prevent the debris thrown upward by the filter screen 53 from falling through the gap between the mesh frame 52 and the water retaining shell 41.

[0032] The secondary cylindrical centrifugal mechanism 6 includes a mesh cover 62, an annular connecting frame 63 is fixedly mounted on the outer wall of the mesh cover 62, and an annular blocking cover 61 is fixedly mounted on one end of the mesh cover 62.

[0034] In summary, the water-containing slag is poured into the upper hopper 1, and the slag is guided to the first-stage funnel-shaped centrifugal mechanism 5 through the upper hopper 1. The motor 72 is used to drive the connecting seat 55 to rotate at a high speed. After the slag falls onto the connecting seat 55, the connecting seat 55 is used to drive the hitting pile 54 to rotate at a high speed, and the connecting seat 55 is used to drive the hitting pile 54 to hit the slag, so as to crush and stir the slag. The connecting seat 55 drives the net frame 52 and the filter screen 53 to rotate at a high speed, so that the net frame 52 and the filter screen 53 drive the slag to rotate, and the centrifugal force is used to drive the slag to slide upward along the filter screen 53, and at the same time, the centrifugal force is used to pass the muddy water in the slag through the filter screen 53. After separation and screening, when the water thrown out by the first-stage funnel-shaped centrifugal mechanism 5 sticks to the water retaining shell 41, the water can be introduced into the bucket-shaped pipe 42 through the water retaining shell 41, and then introduced into the drain pipe 43 through the bucket-shaped pipe 42, and the water is discharged outward through the drain pipe 43. When the material enters the second-stage cylindrical centrifugal mechanism 6, the annular protective plate 51 drives the annular connecting frame 63 to rotate the mesh cover 62 at a high speed, so that the slag thrown onto the mesh cover 62 slides down along the mesh cover 62, and the centrifugal force is used for secondary dehydration along the way, so that the thrown muddy water enters the cover body 31. When the separated muddy water is thrown to the inner wall of the cover body 31, it is discharged to the frame 2 through the cover body 31.
