Through the cooperation of the sliding rod 4 and the sliding sleeve 6, when the threaded rod 3 and the threaded sleeve 5 drive the sliding rod 4 and the sliding sleeve 6 to slide, the sliding rod 4 and the sliding sleeve 6 play a guiding role on the gantry 7, thereby preventing the gantry 7 from sliding. The phenomenon of deviation occurs, which improves the stability of the gantry 7 when it slides on the top of the drying device 1. The front side of the left fixed frame 2 is fixedly connected with a fixed cover 8, and a motor 9 is fixedly installed in the inner cavity of the fixed cover 8. The front side of the left fixed frame 2 is installed with a motor 9. The output shaft of the motor 9 passes through the inner cavity of the left fixed frame 2 and is fixedly connected to the threaded rod 3. A fixed plate 11 is provided at the bottom of the inner cavity of the gantry 7. Four support columns 10 are fixedly connected to the bottom of the inner cavity of the gantry 7. The four support columns 10 are fixedly connected to the fixed plate 11. The left and right sides of the bottom of the fixed plate 11 are fixedly connected with side baffles 12. The two side baffles 12 are rotatably connected to the opposite side with a rotating rod 13. The side baffles 12 The surface of the fixed plate 11 is fixedly connected to two swing plates 14, and a sliding rod 15 is fixedly connected between the two swing plates 14. A rotatable connecting rod 18 is provided at the central axis of the fixed plate 11. The bottom of the connecting rod 18 is fixedly connected to the mounting plate 19. The surface of the sliding rod 15 is slidably connected to a sliding ring 16. The top of the sliding ring 16 is fixedly connected to a mounting rod 17. The mounting rod 17 is rotatably connected to the end of the mounting plate 19 away from the connecting rod 18. Through the cooperation of the sliding ring 16 and the mounting rod 17, when the sliding ring 16 and the mounting rod 17 drive the two swing plates 14 to swing back and forth, the sliding ring 16 and the mounting rod 17 play a role in limiting the swing plate 14, ensuring that the swing plate 14 will not lose its position when swinging. The control phenomenon improves the frequency consistency of the swinging plate 14 during swinging and the stability of the swinging plate 14 during the swinging process. A flap 22 is provided at the bottom of the rotating rod 13, and a motor 20 is fixedly installed at the central axis of the top of the fixed plate 11. The output shaft of the motor 20 is fixedly connected to the connecting rod 18.

Since the sliding ring 16 slides back and forth on the surface of the slide rod 15, the swing plate 14 drives the rotating rod 13 to rotate between the two side baffles 12, and then the rotating rod 13 rotates in the hole opened in the side baffle 12. Then the rotating rod 13 will drive the flap 22 to swing back and forth in the inner cavity of the drying device 1 through the connecting plate 21, and flip the filter cake in the inner cavity of the drying device 1. Then the motor 9 in the inner cavity of the fixed cover 8 will be turned on, and the output shaft of the motor 9 will drive the threaded rod 3 to rotate in the inner cavity of the left fixed frame 2, and then the threaded rod 3 will drive the threaded sleeve 5 to slide, and at the same time the sliding sleeve 6 will slide on the surface of the sliding rod 4, so that the threaded sleeve 5 and the sliding sleeve 6 will drive the gantry 7 to slide on the top of the drying device 1, and then the flap 22 will swing in all directions in the inner cavity of the drying device 1. Finally, the filter cake in the inner cavity of the drying device 1 can be fully dried.
