[0039] This embodiment has the following advantages:

[0040] The sliding frame 21 is driven to slide on the frame 11 by rotating the driving member 23 and the driving screw 22, so that the sliding frame 21 drives the pre-dehydration device to move above the main dehydration tank 12, so that the pre-dehydration device can deliver the pulp to different positions of the main dehydration tank 12 along with the sliding frame 21 after squeezing and dehydrating the pulp, thereby improving the uniformity of the pulp in the main dehydration tank 12, and achieving the advantage of a more uniform dehydration effect.

[0041] The guide rails 24 and the frame 11 provide support forces to the sliding frame 21 at different positions, thereby improving the structural stability between the sliding frame 21 and the frame 11 .

[0042] When the two squeezing plates 51 are brought close to each other, the pipe body 31 is blocked by the blocking block 44, thereby reducing the pulp that has not been squeezed and dehydrated and falls into the main dewatering tank 12, thereby improving the dewatering effect of the pulp.

[0043] When the squeezing plate 51 moves toward the squeezing block 32 and squeezes the pulp, the connecting block 41 cooperates with the squeezing block 32 to prevent the squeezed pulp from flowing above the squeezing block 32 , thereby ensuring that the pulp can be squeezed and dehydrated by the squeezing plate 51 and the squeezing block 32 .

Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
