[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a solid-liquid separation device for wastewater treatment, including a separation tank 1, an inlet pipe 3, a drain pipe 5, and a support leg 4 fixedly installed at the bottom of the separation tank 1. A dewatering component 2 is movably installed inside the separation tank 1. The separation tank 1 includes a tank body 11 and a top cover 12 movably hinged to the top of the tank body 11. The right side and left side of the tank body 11 are respectively provided with an opening 13 and a waste discharge port 14. An installation sleeve 15 is fixedly installed on the outside of the waste discharge port 14. A cover plate 16 is movably hinged to the outside of the installation sleeve 15. An ear plate 17 adapted to the cover plate 16 is fixedly installed on the left side of the tank body 11. A fixing pin 18 is movably installed inside the cover plate 16 and the ear plate 17.

[0024] The inner wall of the housing 11 is coated with a hydrophobic coating to facilitate the rapid downward flow and discharge of any adhering liquid. The dewatering assembly 2 includes a bearing sleeve 21 fixedly installed inside the housing 11. A filter cartridge 22 with a left-side opening is movably installed inside the bearing sleeve 21. The left side of the filter cartridge 22 is adapted to the mounting sleeve 15. A fixing bracket 23 is fixedly installed on the right side of the housing 11. A telescopic rod 24 is fixedly installed on the outer side of the fixing bracket 23. A pusher plate 25 located inside the filter cartridge 22 is fixedly installed on the inner side of the telescopic rod 24.

[0025] By removing the retaining pin 18, the cover plate 16 is rotated downwards and opened, thereby opening the waste discharge port 14. The control telescopic rod 24 can drive the pusher plate 25 to move, pushing the solid impurities filtered in the filter cylinder 22 towards the waste discharge port 14 for cleaning. At the same time, the top cover 12 of the box body 11 can be rotated open to facilitate internal cleaning, thus making the cleaning work more convenient.

[0026] An opening adapted to the telescopic rod 24 is provided on the right side of the filter cylinder 22. The telescopic rod 24 passes through the through-hole 13 and the opening on the right side of the filter cylinder 22 and is connected to the pusher plate 25. Driven by the telescopic rod 24, the pusher plate 25 can move inside the filter cylinder 22, effectively pushing the solid impurities accumulated inside the filter cylinder 22 toward the waste discharge port 14 for easy cleaning.

[0027] The pusher plate 25 is circularly shaped to fit the filter cylinder 22. A brush is provided on the outer side of the pusher plate 25. The brush effectively cleans the inner wall of the filter cylinder 22, preventing solid impurities from adhering to it and improving cleaning efficiency. The circular shape of the pusher plate 25 ensures a tight fit with the inner wall of the filter cylinder 22, improving the uniformity of pushing and cleaning.

[0028] A sealing strip 110 is movably engaged on the inner side of the cover plate 16, and an allowance opening 19 adapted to the water inlet pipe 3 is provided on the outer side of the cover plate 16. When the cover plate 16 is closed, the sealing strip 110 can effectively ensure the sealing between the cover plate 16 and the box 11, preventing wastewater from leaking from the gaps. The allowance opening 19 allows the water inlet pipe 3 to pass smoothly, ensuring that the water inlet pipe 3 is not obstructed when passing through the cover plate 16.

[0029] Please see Figure 1 and Figure 2 The inlet pipe 3 is fixedly installed on the upper left side of the housing 11. The inlet pipe 3 extends into the interior of the filter cylinder 22. The drain pipe 5 is fixedly connected to the bottom of the housing 11. The inlet pipe 3 can send wastewater into the interior of the filter cylinder 22 to ensure that the wastewater comes into contact with the inside of the filter cylinder 22 for solid-liquid separation. The drain pipe 5 is equipped with a solenoid valve. The opening and closing of the solenoid valve can control the discharge of wastewater and facilitate the adjustment of the wastewater treatment process according to actual needs.

[0030] Please see Figure 4 and Figure 5A mounting bracket 26 is fixedly installed on the left side of the housing 11, and a gear 27 located inside the opening 13 is fixedly installed on the right side of the filter cylinder 22. A drive motor 28 is fixedly installed on the outside of the mounting bracket 26, and a gear 29 meshing with the gear 27 is fixedly installed on the outside of the output shaft of the drive motor 28. After the drive motor 28 starts, it can drive the gear 27 to rotate through the gear 29, thereby driving the filter cylinder 22 to rotate around its axis. This helps the wastewater to be evenly distributed inside the filter cylinder 22, improving the efficiency of solid-liquid separation. During the rotation of the filter cylinder 22, solid impurities in the wastewater are subjected to centrifugal force and gradually deposit on the inner wall of the filter cylinder 22, while the clarified liquid flows out through the filter layer of the filter cylinder 22, achieving effective solid-liquid separation.

[0031] Gear 27 is set on the same axis as filter cartridge 22, and gear 29 is set above gear 27, which ensures that drive motor 28 can drive filter cartridge 22 to rotate smoothly and effectively, making the rotation more stable and reducing vibration and noise caused by eccentric rotation.

[0032] Working principle: When in use, wastewater is injected into the filter cylinder 22 through the water inlet pipe 3. By turning on the drive motor 28, the gear 29 connected to it can be rotated. The gear 29 and gear 27 mesh together, thereby driving the filter cylinder 22 in the bearing sleeve 21 to rotate. The filter cylinder 22 is meshed on the outside, which allows the liquid entering the filter cylinder 22 to be thrown out, while the solids are intercepted inside the filter cylinder 22. As the filter cylinder 22 rotates, centrifugal force is generated to throw the liquid out, ensuring the separation effect. The separated liquid is discharged from the drain pipe 5 at the bottom of the box 11.

[0033] During cleaning, by removing the fixing pin 18 that limits the cover plate 16 inside the ear plate 17, the cover plate 16 is rotated downwards along its connection point to open, thereby opening the waste discharge port 14. By controlling the telescopic rod 24, the pusher plate 25 located inside the filter cylinder 22 can be moved laterally. The bristles on the side of the pusher plate 25 adhere to the inner wall of the filter cylinder 22, pushing the solid impurities filtered inside the filter cylinder 22 towards the waste discharge port 14 for cleaning. At the same time, the top cover 12 on the top of the box 11 can be rotated and opened, allowing the interior of the box 11 and the filter cylinder 22 to be rinsed and cleaned separately through an external water pipe.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
