A forward and reverse motor 3 is fixedly connected to the side of the power plate 2 away from the main body 1. Matching the forward and reverse motor 3 are a power supply, wiring, controller, and microcomputer structure. Since the forward and reverse motor 3 is not a major structure, it will not be described in detail. Two symmetrical limiting grooves 18 are provided on the right side of the main body 1. The interiors of the two limiting grooves 18 are evenly slidable. The device is connected to a limit block 5, and a collection box 4 for collection is fixedly connected between the two limit blocks 5. A handle for easy pulling is provided on one side of the collection box 4. The collection box 4 is fixed to the surface of the device body 1 by bolts. The processed pulp can be collected and processed in a timely manner through the collection box 4, reducing the tedious steps of frequent pulp collection and processing by the staff and effectively reducing the labor intensity of the staff. The power plate 2 has a power groove 13 inside. The output end of the forward and reverse motor 3 rotates through the power plate 2 and extends into the inside of the power groove 13.

A filter frame 8 for filtering pulp is slidably connected inside the moving groove 19. The pulverized pulp can be filtered and screened through the filter frame 8.

[0026] Please refer to Figure 4 The shaking filter includes a rotating rod 16, which is rotatably connected to the inside of the power groove 13. A sprocket 14 is fixedly connected to the left side of the rotating rod 16. The surface of the sprocket 14 has a groove. The end of the sprocket 14 away from the rotating rod 16 is fixedly connected to the output end of the forward and reverse motor 3. The right side of the rotating rod 16 rotates through the device body 1 and extends into the interior of the device body 1. Multiple protrusions 17 are fixedly connected to the surface of the rotating rod 16. The protrusions 17 are located below the filter frame 8. The operator starts the forward and reverse motor 3 through the controller and microcomputer structure. The output of the forward and reverse motor 3... The output end drives the sprocket 14 to rotate, the sprocket 14 drives the rotating rod 16 to rotate, and the rotating rod 16 drives the protrusion 17 to rotate. The surface of the protrusion 17 contacts the bottom of the filter frame 8 and causes it to vibrate up and down under force. By making the filter frame 8 vibrate up and down, it helps the filter holes to more easily drain the water in the pulp, improves the dewatering efficiency, reduces the residual air bubbles in the pulp, and improves the uniformity and strength of the final paper products. The up and down vibration can also reduce the wear of the filter cloth or filter screen, extend the service life of the equipment, and the continuous vibration helps to reduce the probability of pulp adhering to the filter cloth, reduce the cleaning frequency, and reduce maintenance costs.

A threaded rod 10 extending into the power groove 13 is rotatably connected inside the transmission groove 9.

[0028] Please refer to Figure 3 A sprocket 14 is also fixedly connected to the surface of the threaded rod 10. A chain 15 is provided in the groove on the sprocket 14. Through the cooperation between the chain 15 and the sprocket 14, the rotating rod 16 and the threaded rod 10 can rotate synchronously.

[0029] Please refer to Figure 3 The transmission groove 9 has a sliding connection to the transmission rod 11. The surface of the threaded rod 10 is threadedly connected to the inside of the transmission rod 11. By rotating the threaded rod 10, the threaded rod 10 can drive the transmission rod 11 to slide.

[0030] Please refer to Figure 6 The bottom of the transmission rod 11 is provided with a sliding groove 20.

[0033] Working principle: The operator starts the forward and reverse motor 3 through the controller and microcomputer structure. The output end of the forward and reverse motor 3 drives the sprocket 14 to rotate. The sprocket 14 drives the rotating rod 16 to rotate. The rotating rod 16 drives the protrusion 17 to rotate. The surface of the protrusion 17 contacts the bottom of the filter frame 8 and makes it vibrate up and down under force. At the same time, the output end of the forward and reverse motor 3, through the cooperation of the chain 15 and the sprocket 14, can drive the threaded rod 10 and the rotating rod 16 to rotate synchronously. The threaded rod 10 drives the transmission rod 11 to reciprocate. The transmission rod 11 drives the telescopic frame 12 to reciprocate. During the sliding process of the telescopic rod 12, the inclined surface set at its bottom can disturb the pulp inside the filter frame 8.
