Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Embodiment 1

[0021] Referring to Figures 1-5, a pulp dehydration device, comprising an outer barrel 1. A power shaft 3 is rotatably connected to the bottom of the outer barrel 1. The lower end of the power shaft 3 is connected to an external power device. The power shaft 3 can be driven to rotate by the external power device. The upper end of the power shaft 3 extends into the outer barrel 1 and is fixedly connected to a dehydration cylinder 2. The rotation of the power shaft 3 can drive the dehydration cylinder 2 to rotate. The inside of the dehydration cylinder 2 is used to contain the pulp to be dehydrated. The dehydration cylinder 2 can dehydrate the inside of the pulp during rotation. The upper end of the outer barrel 1 is threadedly connected with a cover 12. The cover 12 is threadedly connected to the outer barrel 1, which is convenient for disassembly and assembly. A fixing plate 9 is fixedly installed inside the cover 12. A connecting shaft 10 is rotatably connected to the lower surface of the fixing plate 9. The lower end of the connecting shaft 10 is fixedly installed with a linkage cover 11. The linkage cover 11 is rotatably connected to the fixing plate 9 through the connecting shaft 10. The lower end of the linkage cover 11 cooperates with the upper end of the dehydration cylinder 2. When the linkage cover 11 cooperates with the dehydration cylinder 2, the rotation of the dehydration cylinder 2 can drive the linkage cover 11 to rotate, and the rotation of the linkage cover 11 can drive the connecting shaft 10 to rotate. The fixing plate 9 provides support for the connecting shaft 10 and the linkage cover 11.

[0022] An extrusion mechanism is provided inside the cover 12. The extrusion mechanism includes a lead screw 8. The lead screw 8 is rotatably arranged inside the cover 12. The end of the lead screw 8 is in transmission connection with an external motor. The lead screw 8 can be driven to rotate by the external motor. A lifting pair 7 is threadedly connected to the outside of the lead screw 8. The rotation of the lead screw 8 can drive the lifting pair 7 to move up and down. A connecting rod 6 is rotatably installed on the lower surface of the lifting pair 7. The length direction of the connecting rod 6 is parallel to the length direction of the lead screw 8 and both are vertically arranged. The connecting rod 6 is coaxially arranged with the power shaft 3. The up and down movement of the lifting pair 7 can drive the connecting rod 6 to move up and down. The lower end of the connecting rod 6 penetrates through the connecting shaft 10 and extends below the linkage cover 11. A pressing plate 4 is fixedly installed at the end of the connecting rod 6 extending below the linkage cover 11. The up and down movement of the connecting rod 6 can drive the pressing plate 4 to move up and down. The cross section of the connecting rod 6 is square. The connecting rod 6 is in up and down sliding fit with the connecting shaft 10 and the inner wall of the linkage cover 11. When the connecting shaft 10 and the linkage cover 11 rotate, they can drive the connecting rod 6 to rotate, and the rotation of the connecting rod 6 can drive the pressing plate 4 to rotate.

[0023] During the dehydration process of the dehydration cylinder 2, the linkage cover 11 cooperates with the dehydration cylinder 2. When the dehydration cylinder 2 rotates, it can drive the linkage cover 11 and the connecting shaft 10 to rotate. When the connecting shaft 10 and the linkage cover 11 rotate, they can drive the connecting rod 6 to rotate. When the connecting rod 6 rotates, it can drive the pressing plate 4 to rotate. The pressing plate 4 rotates synchronously with the dehydration cylinder 2. Start the external motor to drive the screw rod 8 to rotate. When the screw rod 8 rotates, it can drive the lifting pair 7 to move downward. When the lifting pair 7 moves downward, it will drive the connecting rod 6 to move downward. When the connecting rod 6 moves downward, it can drive the pressing plate 4 to move downward. The pressing plate 4 can squeeze the inside of the pulp being dehydrated, and can effectively squeeze out and throw out the water inside the pulp. A cleaning ring 5 is fixedly installed on the side of the pressing plate 4. The cleaning ring 5 is in contact with the side wall of the dehydration cylinder 2. When driving the pressing plate 4 to move downward, the cleaning ring 5 can scrape the pulp adhered to the side wall of the dehydration cylinder 2 downward, which can comprehensively squeeze the pulp and prevent the pulp adhered to the inner wall of the dehydration cylinder 2 from retaining moisture inside and affecting the dehydration effect.

[0024] A fixing frame 13 is fixedly installed on the inner side wall of the outer barrel 1. A cleaning strip 14 is fixedly installed on the surface of the fixing frame 13. The surface of the cleaning strip 14 is attached to the outer surface of the dehydration cylinder 2. The cleaning strip 14 is arranged to fit the contour of the dehydration cylinder 2. When the dehydration cylinder 2 rotates for dehydration, the cleaning strip 14 can clean the filter holes on the side wall of the dehydration cylinder 2 and prevent the filter holes on the side wall of the dehydration cylinder 2 from being blocked by pulp.

[0025] Working principle: During the working process of this pulp dehydration device, the pulp to be dehydrated is put into the dehydration cylinder 2, and the cover 12 is covered. The linkage cover 11 cooperates with the dehydration cylinder 2. Start the external power device to drive the power shaft 3 to rotate. When the power shaft 3 rotates, it can drive the dehydration cylinder 2 to rotate. When the dehydration cylinder 2 rotates, it can throw out the water inside the pulp. When the dehydration cylinder 2 rotates, it can drive the linkage cover 11 to rotate. When the linkage cover 11 rotates, it can drive the connecting rod 6 to rotate. When the connecting rod 6 rotates, it can drive the pressing plate 4 to rotate synchronously with the dehydration cylinder 2. Start the external motor to drive the screw rod 8 to rotate. When the screw rod 8 rotates, it can drive the lifting pair 7 to move downward. When the lifting pair 7 moves downward, it can drive the pressing plate 4 to move downward through the connecting rod 6. When the pressing plate 4 moves downward, it can squeeze the pulp. Squeezing the pulp during the dehydration process can further fully remove the water inside it. During the rotation of the dehydration cylinder 2, the cleaning strip 14 can clean the filter holes on the side wall of the dehydration cylinder 2 to prevent the filter holes on the side wall of the dehydration cylinder 2 from being blocked and affecting the dehydration work.
