The first connecting rod 5 and the second connecting rod 6 are used to drive the support plate 7 to move up and down. The support plate 7 is used to support the support block 8 and the support plate 9.

[0026] Refer to Figure 3, a motor 12 is fixedly connected to the inner wall of the housing 11, an output end of the motor 12 is fixedly connected to a propeller 13, an outer wall of the propeller 13 is disposed inside the housing 11, a ring-shaped housing 14 is fixedly connected to the inner wall of the housing 11, a second hydraulic cylinder 15 is fixedly connected to an outer wall of the ring-shaped housing 14, and an output end of the second hydraulic cylinder 15 is fixedly connected to a rotating plate 16;

[0027] Specifically, the housing 11 is used to fix the motor 12 to prevent the motor 12 from shifting in position during use. The motor 12 is used to drive the propeller 13 to rotate. A hole is formed at the bottom of the housing 11 to allow the liquid to flow out smoothly. The discharge plate 10 is used to support the discharge of the squeezed dry solid.

[0028] Refer to Figure 4 , a support rod 17 is fixedly connected to an outer wall of the rotating plate 16, a rotating ring 18 is fixedly connected to the outer wall of the rotating plate 16, an outer wall of the rotating ring 18 is rotatably connected to the inner wall of the ring-shaped housing 14, a fan blade 19 is fixedly connected to an inner wall of the rotating ring 18, a mounting post 20 is fixedly connected to an outer wall of the fan blade 19, and a support ring 21 is disposed on the outer wall of the mounting post 20:

[0030] Working principle: When the device needs to be used, it is pushed by the first hydraulic cylinder 3. When the first hydraulic cylinder 3 is pushed, it will drive the fixed column 4 at its output end to move. When the fixed column 4 moves, it will drive the first connecting rod 5 rotatably connected to its outer wall to rotate. The lower outer wall of the first connecting rod 5 will rotate inside the inner wall of the base 1, and the upper outer wall of the first connecting rod 5 will slide inside the inner wall of the support plate 7.

Thus, it can achieve the effect of optimizing the pressure distribution and material flow state inside the pulp extruder by changing the height of the device, improving the pulp extrusion effect and production efficiency. By pushing with the second hydraulic cylinder 15, when the second hydraulic cylinder 15 is pushed, it will drive the rotating plate 16 at its output end to rotate. When the rotating plate 16 rotates, it will drive the support rod 17 fixedly connected to its outer wall to move. When the support rod 17 moves, it will drive the next rotating plate 16 to rotate.

When the rotating ring 18 rotates, it will drive the fan blade 19 fixedly connected to its inner wall to rotate. When the fan blade 19 rotates, it will drive the mounting column 20 to rotate. Finally, the mounting column 20 will rotate inside the inner wall of the support ring 21. Thus, it can achieve the effect of making the operation of the pulp extruder more stable and reliable, reducing equipment vibration and noise caused by thermal deformation, and ensuring the stability of the pulp extrusion quality. This large double-screw pulp extruder can not only achieve the effect of optimizing the pressure distribution and material flow state inside the pulp extruder by changing the height of the device, improving the pulp extrusion effect and production efficiency, but also achieve the effect of making the operation of the pulp extruder more stable and reliable, reducing equipment vibration and noise caused by thermal deformation, and ensuring the stability of the pulp extrusion quality.
