[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.

[0022] Referring to Figure 1 - Figure 5 As shown, the present utility model provides a technical solution: a sludge dewatering device, including a conveyor belt 1, an extrusion belt 2 is installed on the top of the conveyor belt 1, long plates 3 are fixedly connected to both the front end and the rear end of the top of the conveyor belt 1, a funnel shell 4 is fixedly connected to the top of the long plate 3, a square groove 5 is opened on one side of the funnel shell 4, an installation frame 6 is slidably connected to the inner wall of the square groove 5, a filter screen 7 is installed inside the installation frame 6, two rotating columns 8 are fixedly connected to one side of the square groove 5, a rotating plate 9 is rotatably connected to the surface of the rotating column 8, a limiting plate 10 is fixedly connected to one side of the rotating plate 9, two first extension plates 11 are fixedly connected to one side of the square groove 5. By the staff inserting the installation frame 6 into the square groove 5, the filter screen 7 is placed inside the funnel shell 4. Then, through the rotational connection of the rotating column 8 and the rotating plate 9, and the design of being fixed to the bottom of the rotating plate 9 by the limiting plate 10, the bottom of the rotating plate 9 is heavier, so that due to its own weight, the bottom is on the top of the first extension plate 11, making the rotating plate 9 abut against one side of the installation frame 6, restricting the installation frame 6 in the square groove 5, realizing the detachable design of the installation frame 6 and the filter screen 7, enabling the sludge flowing inside the funnel shell 4 to be simply filtered through the filter screen 7, preventing larger foreign objects from flowing into the conveyor belt 1 and the extrusion belt 2 during extrusion and causing damage to the device. At the same time, when the filter screen 7 is blocked by impurities, it is convenient for the staff to disassemble the installation frame 6 and the filter screen 7, and replace or dredge the filter screen 7.

[0023] Referring to Figure 1 With Figure 2 As shown, in this embodiment: a spring 12 is fixedly connected to the surface of the rotating plate 9, one end of the spring 12 is fixedly connected to a second extension plate 13, and one side of the second extension plate 13 is fixedly connected to the square groove 5. When the staff rotates the rotating plate 9 upward, the rotating plate 9 pulls the spring 12 to store energy, releasing the restraint of the rotating plate 9 and the limiting plate 10 on the installation frame 6. When the staff releases the rotating plate 9, the force generated by the spring 12 when it rebounds pulls the rotating plate 9 to drive the limiting plate 10 to reset, restricting the initial position of the rotating plate 9, so that the rotating plate 9 is always in a state of restricting the position of the installation frame 6.

[0024] Referring to Figure 1 、 Figure 2 With Figure 3As shown in the figure, in this embodiment: a first chute 14 is provided on the surface of the rotating plate 9, and a first sliding rod 15 is slidably connected to the inner wall of the first chute 14. One end of the first sliding rod 15 is fixedly connected to the second extension plate 13. By the sliding connection between the first chute 14 and the first sliding rod 15, the movement trajectory of the rotating plate 9 is restricted, preventing the rotating plate 9 from tilting when rotating, resulting in excessive contact between the rotating plate 9 and the installation frame 6 and causing the installation frame 6 to shake in the square groove 5.

[0025] Referring to Figure 1 and Figure 2 As shown in the figure, in this embodiment: the spring 12 is placed on the surface of the first sliding rod 15, and the inner wall of the spring 12 is slidably connected to the surface of the first sliding rod 15. By the sliding connection between the spring 12 and the first sliding rod 15, the maximum elastic force of the spring 12 is restricted, and the movement trajectory of the spring 12 is restricted, so that the spring 12 moves closely on the surface of the first sliding rod 15, preventing the spring 12 from curling and winding when rebounding, which affects the normal operation of the component.

[0026] Referring to Figure 1 and Figure 2 As shown in the figure, in this embodiment: a nut block 16 is fixedly installed on one side of the rotating plate 9, and a threaded rod 17 is threadedly connected to the inside of the nut block 16. The staff screws the threaded rod 17 into the top of the first sliding rod 15 through the nut block 16, so that the first sliding rod 15 contacts the threaded rod 17, and the first sliding rod 15 restricts the rotation trajectory of the rotating plate 9, making it no longer able to rotate, thereby preventing the rotating plate 9 from detaching from the surface of the installation frame 6 due to the vibration of the device. When the threaded rod 17 is screwed to the bottom of the first sliding rod 15, the rotating plate 9 can be detached from the surface of the installation frame 6, and the square groove 5 is no longer restricted by the rotating plate 9 and is in an open state, facilitating the staff to install and disassemble the installation frame 6 inside the square groove 5.

[0027] Referring to Figure 3 、 Figure 4 and Figure 5 As shown in the figure, in this embodiment: circular grooves 18 are provided at both ends of the installation frame 6, and a second sliding rod 19 is slidably connected to the inner wall of the circular groove 18. One end of the second sliding rod 19 is fixedly connected to the inner wall of the square groove 5. By inserting the second sliding rod 19 into the circular groove 18, when the staff inserts the installation frame 6 into the square groove 5, the second sliding rod 19 is inside the circular groove 18, restricting the position of the installation frame 6 and preventing the installation frame 6 from shaking in the square groove 5, improving the stability of the component operation.

[0028] Referring to Figure 5 and Figure 6As shown in the figure, in this embodiment: a support frame 20 is installed at the top of the extrusion belt 2. One side of the support frame 20 is fixedly connected with a brush 21. The bottom of the brush 21 abuts against the surface of the extrusion belt 2. Through the support frame 20 arranged at the top of the extrusion belt 2, the brush 21 abuts against the surface of the extrusion belt 2. When the extrusion belt 2 operates, the brush 21 sweeps the surface of the extrusion belt 2, thereby sweeping off the impurities attached to the surface of the extrusion belt 2, preventing the extrusion belt 2 from being blocked by sludge, ensuring the cleanliness of the extrusion belt 2, and improving the efficiency of the extrusion belt 2 and the conveyor belt 1 in squeezing and dewatering sludge.

[0029] Working principle: The staff inserts the installation frame 6 into the square groove 5, so that the filter screen 7 is placed inside the funnel shell 4. Then, through the rotational connection between the rotating column 8 and the rotating plate 9, and the design of fixing the limiting plate 10 at the bottom of the rotating plate 9, the bottom of the rotating plate 9 is heavier, and due to its own weight, the bottom of the rotating plate 9 is on top of the first extension plate 11, making one side of the rotating plate 9 abut against the installation frame 6, restricting the installation frame 6 in the square groove 5, realizing the detachable design of the installation frame 6 and the filter screen 7. The sludge flowing inside the funnel shell 4 can be simply filtered through the filter screen 7 to prevent larger foreign objects from flowing into the conveyor belt 1 and the extrusion belt 2 during extrusion and causing damage to the device. At the same time, when the filter screen 7 is blocked by impurities, it is convenient for the staff to disassemble the installation frame 6 and the filter screen 7, replace or dredge the filter screen 7. When the staff rotates the rotating plate 9 upward, the rotating plate 9 pulls the spring 12 to store energy, releasing the restraint of the rotating plate 9 and the limiting plate 10 on the installation frame 6. When the staff releases the rotating plate 9, the force generated by the spring 12 when it rebounds pulls the rotating plate 9 to drive the limiting plate 10 to reset, restricting the initial position of the rotating plate 9, so that the rotating plate 9 is always in a state of restricting the position of the installation frame 6. Through the sliding connection between the first chute 14 and the first sliding rod 15, the movement trajectory of the rotating plate 9 is restricted to prevent the rotating plate 9 from tilting when it rotates, resulting in excessive contact between the rotating plate 9 and the installation frame 6 and causing the installation frame 6 to shake in the square groove 5. Through the sliding connection between the spring 12 and the first sliding rod 15, the maximum elastic force of the spring 12 is restricted, and the movement trajectory of the spring 12 is restricted, so that the spring 12 moves closely on the surface of the first sliding rod 15 to prevent the spring 12 from curling and winding when it rebounds, affecting the normal operation of the components. The staff screws the threaded rod 17 into the top of the first sliding rod 15 through the nut block 16, so that the first sliding rod 15 contacts the threaded rod 17, and the first sliding rod 15 restricts the rotation trajectory of the rotating plate 9, making it no longer able to rotate, thereby preventing the rotating plate 9 from detaching from the surface of the installation frame 6 due to the vibration of the device. When the threaded rod 17 is screwed to the bottom of the first sliding rod 15, the rotating plate 9 can detach from the surface of the installation frame 6, and the square groove 5 is in an open state and is no longer restricted by the rotating plate 9, facilitating the staff to install and disassemble the installation frame 6 inside the square groove 5. Through the insertion of the circular groove 18 and the second sliding rod 19, when the staff inserts the installation frame 6 into the square groove 5, the second sliding rod 19 is inside the circular groove 18, restricting the position of the installation frame 6 to prevent the installation frame 6 from shaking in the square groove 5 and improving the stability of the component operation. Through the support frame 20 arranged at the top of the extrusion belt 2, the brush 21 abuts against the surface of the extrusion belt 2. When the extrusion belt 2 operates, the brush 21 sweeps the surface of the extrusion belt 2, thereby sweeping off the impurities attached to the surface of the extrusion belt 2 to prevent the extrusion belt 2 from being blocked by sludge, ensuring the cleanliness of the extrusion belt 2 and improving the efficiency of the extrusion belt 2 and the conveyor belt 1 in extruding and dehydrating the sludge.
