[0016] like Figure 1-3As shown: A sludge dewatering treatment device includes a hanger 1, with two hangers 1 arranged parallel to each other. The front and rear ends of the hangers 1 extend downwards. A crossbar 2 is fixedly connected between the front bottom ends of the two hangers 1, and a second crossbar 3 is fixedly connected between the rear bottom ends of the two hangers 1. The left and right ends of the crossbar 2 extend downwards, and motors 4 are fixedly installed on the left and right bottom ends of the crossbar 2. The output shafts of the two motors 4 are opposite each other, and rotating shafts 5 are fixedly connected to the opposite ends of the output shafts of the two motors 4. Pulleys 6 are fixedly sleeved on the outer walls of the two rotating shafts 5. The left and right ends of the second crossbar 3 extend downwards, and rotating shafts 7 are fixedly connected to the opposite sides of the left and right bottom ends of the second crossbar 3. Pulleys 8 are rotatably connected to the outer walls of the two rotating shafts 7. A conveyor belt 9 is sleeved between the outer walls of the first pulley 6 and the second pulley 8 on the same side. Several collars 10 are fixedly sleeved on the outer wall of the conveyor belt 9. The collars 10 are evenly distributed along the conveyor belt 9. Hooks 11 are fixedly connected to the bottom of the outer wall of the collars 10. There are frame plates 13 on the rear side of the lower part of the two conveyor belts 9. The front ends of the two frame plates 13 are bent towards the opposite side. Two connecting rods 12 are fixedly connected to the opposite side walls of the two frame plates 13. The two connecting rods 12 are distributed front and back. Both connecting rods 12 extend upward. The top ends of the two connecting rods 12 are fixedly connected to the outer wall of the crossbar 3 and the hanger 1, respectively. Embedding grooves 14 are opened on the opposite side walls of the two frame plates 13. There is a pressing plate 16 inside the embedding groove 14. Cylinders 15 are fixedly installed on the opposite side walls of the two frame plates 13. The cylinder columns of the two cylinders 15 pass through the two frame plates 13 and are fixedly connected to the pressing plate 16, respectively.

[0017] Several extrusion protrusions 17 are fixedly connected to the opposite sidewalls of the two extrusion plates 16. The extrusion protrusions 17 are arc-shaped and elongated. The extrusion protrusions 17 are distributed at equal intervals up and down. The extrusion protrusions 17 of the two extrusion plates 16 are staggered. Several drainage holes 18 are opened on the outer wall of the extrusion plates 16. The drainage holes 18 are evenly distributed between the extrusion protrusions 17.

[0018] The cloth bag 19 is located between the bottom front sides of the two conveyor belts 9. The top two corners of the left and right sides of the cloth bag 19 are fixedly connected to the connecting plates 20. The top of each of the four connecting plates 20 has a connecting hook 22. The top of the connecting hook 22 is fixedly connected to the hanging ring 21. The hanging ring 21 is hung on the corresponding hanging hook 11 above. The four connecting plates 20 are respectively hung on the four connecting hooks 22.

[0019] First, the sludge-filled bag 19 is hung on the hook 11 on the conveyor belt 9 via the connecting hook 22 and the hanging ring 21 on the connecting plate 20 at its top. The left and right sides of the bag 19 are respectively hung on the two corresponding conveyor belts 9 to ensure that the bag 19 is suspended stably.

[0020] Subsequently, the two motors 4 are started. The output shaft of the motor 4 drives the rotating shaft 5 to rotate, which in turn drives the pulley 6 to rotate. Since the pulley 6 and the pulley 8 are connected by the conveyor belt 9, the rotation of the pulley 6 will drive the conveyor belt 9 to move. The movement of the conveyor belt 9 will drive the cloth bag 19 hanging on the hook 11 to move backward.

[0021] When the filter bag 19 moves to the position between the two support plates 13, the two cylinders 15 start to work. The cylinder column of the cylinder 15 pushes the extrusion plate 16 closer to the filter bag 19 and extrudes the filter bag 19. Since the extrusion plate 16 has arc-shaped long strip extrusion protrusions 17 on the opposite side wall, these protrusions can more effectively extrude the filter bag 19 and help the water in the sludge to be filtered out through the filter bag 19.

[0022] During the squeezing process, the water in the sludge is filtered out by the cloth bag 19 and discharged through the drainage holes 18 on the squeezing plate 16. The drainage holes 18 are evenly distributed between the squeezing protrusions 17 to ensure that the water can be discharged smoothly.

[0023] After the filter bag 19 is fully squeezed, most of the water in the sludge has been filtered out. At this point, the operation of the cylinder 15 can be stopped. The cylinder 15 drives the squeezing plate 16 to reset, and the motor 4 continues to drive the conveyor belt 9 to send the dewatered filter bag 19 out of the processing device.

[0024] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
