Description

Technical Field

[0001] This utility model relates to the technical field of dewatering devices, specifically to a sludge dewatering device for sewage treatment. Background Technology

[0002] Sludge dewatering devices play a crucial role in wastewater treatment. Their main purpose is to separate the solid and liquid components of the excess sludge produced by wastewater treatment plants, thereby reducing the water content and volume of the sludge to facilitate subsequent treatment, transportation, and disposal.

[0003] The existing technology has the following problems:

[0004] The existing equipment cannot clear the inside of the discharge pipe during the discharge process. As the degree of blockage increases, the flow resistance of the sludge increases, and it will be unable to be discharged smoothly due to pipe blockage. This will cause the sludge to accumulate in the dewatering device, affecting the normal operation of the entire dewatering system. In addition, the existing equipment cannot quickly connect and install the drain pipe. Time is very valuable at the sewage treatment site. If the drain pipe cannot be quickly connected and installed, the sludge dewatering device will not be able to be put into operation in time. During the installation process, the equipment is in a waiting state and cannot exert its due sludge treatment capacity. Utility Model Content

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1-2As shown, this utility model provides a sludge dewatering device for sewage treatment, including a base 1, multiple support legs 2 fixedly connected to the upper side of the base 1, a fixed tank 3 fixedly connected to the upper end of the support legs 2, a feed pipe 4 fixedly connected to the upper side of the fixed tank 3, a motor 5 fixedly connected to the outer wall of the fixed tank 3, a bevel gear 9 fixedly connected to the output shaft of the motor 5, multiple liquid flow limiting rings 7 arranged vertically and vertically connected to the inner surface of the fixed tank 3, a rotating tank 6 fixedly connected to the inner surface of the multiple liquid flow limiting rings 7, a solid-liquid separation plate 10 provided on the outer wall of the rotating tank 6, the outer wall of the feed pipe 4 rotatably connected to the rotating tank 6, a bevel gear ring 8 fixedly connected to the upper side of the rotating tank 6, the outer wall of the bevel gear 9 meshing with the bevel gear ring 8, and the lower part of the fixed tank 3... A connecting pipe 11 is fixedly connected to the side, and a connecting seat 14 is fixedly connected to the outer wall of the connecting pipe 11. A drain pipe 12 is movably connected inside the connecting seat 14. A discharge pipe 13 is fixedly connected to the lower end of the rotating tank 6. A valve is installed inside the discharge pipe 13. After the motor 5 starts, its output shaft drives the bevel gear 9 to rotate. Since the bevel gear 9 is meshed with the bevel gear ring 8, it drives the rotating tank 6 to rotate inside the fixed tank 3. Sewage enters the rotating tank 6 through the feed pipe 4. During the rotation of the rotating tank 6, the solid-liquid separation plate 10 plays a role in separating sludge from liquid. The separated liquid is discharged through structures such as the liquid flow limiting ring 7, while the sludge is discharged through the discharge pipe 13. The connecting seat 14 is used to connect the drain pipe 12 so as to discharge the separated liquid.

[0025] like Figure 2-3 As shown, this utility model provides a technical solution: Preferably, a fixing plate 16 is fixedly connected to the outer wall of the discharge pipe 13, an electric telescopic rod 17 is fixedly connected to the lower side of the fixing plate 16, a lifting plate 15 is fixedly connected to the output end of the electric telescopic rod 17, a plurality of limiting rods 18 are fixedly connected to the upper side of the lifting plate 15, the outer wall of the limiting rods 18 is slidably connected to the discharge pipe 13, a plurality of connecting plates 19 are fixedly connected to the upper side of the lifting plate 15, and a plurality of triangular blocks 20 are fixedly connected to the opposite surfaces of two connecting plates 19. When it is necessary to unclog the discharge pipe 13, the device is activated. The electric telescopic rod 17 drives the lifting plate 15 to move up and down. When the lifting plate 15 moves, the limiting rod 18 slides in the discharge pipe 13, which plays a guiding and limiting role to ensure that the lifting plate 15 moves smoothly. At the same time, the lifting plate 15 drives the connecting plate 19 and the triangular block 20 to move synchronously. The triangular block 20 is constantly agitated inside the discharge pipe 13 to break up and clear the sludge blocked in the discharge pipe 13, ensuring that the discharge pipe is unobstructed and maintaining a stable discharge speed. When the discharge pipe 13 is not blocked, the sludge has low flow resistance and can be discharged at a uniform speed.

[0026] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, two positioning posts 21 are fixedly connected to the lower side of the connecting seat 14, two positioning plates 22 are fixedly connected to the outer wall of the drain pipe 12, the outer walls of the positioning posts 21 are movably connected to the positioning plates 22, two slots 29 are opened on the outer wall of the drain pipe 12, two knobs 23 are rotatably connected to the upper side of the connecting seat 14, a threaded rod 24 is fixedly connected to the lower side of the knobs 23, a lifting block 25 is threadedly connected to the outer wall of the threaded rod 24, the outer wall of the threaded rod 24 is rotatably connected to the connecting seat 14, the lifting block 25 is threadedly connected to the outer wall of the threaded rod 24, a rotating plate 26 is rotatably connected to the side of the lifting block 25 near the drain pipe 12, an L-shaped insert 28 is rotatably connected to the other end of the rotating plate 26, and two limiting plates 27 are fixedly connected to the inner surface of the connecting seat 14. The outer wall of 27 is slidably connected to the L-shaped insert 28, and the outer wall of the L-shaped insert 28 is movably connected to the slot 29. When installing the drain pipe 12, first put the positioning plate 22 on the drain pipe 12 onto the positioning post 21 to initially determine the position of the drain pipe 12. Then turn the knob 23, which drives the threaded rod 24 to rotate. Since the threaded rod 24 is threadedly connected to the lifting block 25, the lifting block 25 will move up and down along the threaded rod 24. As the lifting block 25 moves downward, the rotating plate 26 drives the L-shaped insert 28 to move. Under the limiting action of the limiting plate 27, the L-shaped insert 28 is accurately inserted into the slot 29 of the drain pipe 12, thereby realizing a quick and stable connection between the drain pipe 12 and the connecting seat 14. When disassembling, turn the knob 23 in the opposite direction to make the L-shaped insert 28 exit from the slot 29, and the drain pipe 12 can be quickly disassembled.

[0027] The working principle of this sludge dewatering device used for sewage treatment will be explained in detail below.

[0028] like Figure 1-5As shown, when it is necessary to unclog the discharge pipe 13, the electric telescopic rod 17 is activated. The output end of the electric telescopic rod 17 drives the lifting plate 15 to move up and down. When the lifting plate 15 moves, the limiting rod 18 slides inside the discharge pipe 13, which plays a guiding and limiting role, ensuring that the lifting plate 15 moves smoothly. At the same time, the lifting plate 15 drives the connecting plate 19 and the triangular block 20 to move synchronously. The triangular block 20 continuously stirs inside the discharge pipe 13, breaking and unclogging the sludge blocked in the discharge pipe 13, ensuring that the discharge pipe is unobstructed and maintaining a stable discharge speed. When the discharge pipe 13 is not blocked, the sludge has low flow resistance and can be discharged at a uniform speed. When installing the drain pipe 12, first... The positioning plate 22 on the water pipe 12 is fitted onto the positioning post 21 to initially determine the position of the drain pipe 12. Then, the knob 23 is turned, which drives the threaded rod 24 to rotate. Since the threaded rod 24 is threadedly connected to the lifting block 25, the lifting block 25 will move up and down along the threaded rod 24. As the lifting block 25 moves downward, the rotating plate 26 drives the L-shaped insert 28 to move. Under the limiting action of the limiting plate 27, the L-shaped insert 28 is accurately inserted into the slot 29 of the drain pipe 12, thereby realizing a quick and stable connection between the drain pipe 12 and the connecting seat 14. When disassembling, the knob 23 is turned in the opposite direction to make the L-shaped insert 28 exit from the slot 29, and the drain pipe 12 can be quickly disassembled.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
