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. Example 1

[0022] As attached Figures 1 to 4 The wastewater drainage structure shown includes a treatment tank 1. A positioning groove 2 is provided on the edge of the treatment tank 1. A guide rod 3 is fixedly installed inside the positioning groove 2. A filter screen 4 is detachably installed inside the treatment tank 1. A fixing plate 5 is fixedly connected to the edge of the filter screen 4. The fixing plate 5 is positioned along the guide rod 3. A guide plate 6 is fixedly connected above the filter screen 4. A strip-shaped limiting hole 7 is provided on the upper side of the guide plate 6. A brush plate 8 is movably installed inside the strip-shaped limiting hole 7. A cleaning plate 9 is movably installed at the bottom of the brush plate 8. A tank cover 13 is detachably installed on the top of the treatment tank 1. A sealing gasket 15 is fixedly connected to the bottom of the tank cover 13.

[0023] Wastewater is first guided into the treatment tank 1 through the inlet pipe 18. Here, a highly efficient filtration mechanism is activated. The treatment tank 1 contains a filter screen 4, made of high-quality materials, which can accurately intercept various impurities in the wastewater, such as suspended solids and particulate matter, ensuring effective purification of the wastewater during its flow. This significantly improves the efficiency and quality of wastewater treatment. Furthermore, the frame structure of the treatment tank 1 not only enhances overall stability and increases the cleaning area, making subsequent maintenance more convenient and efficient, but also incorporates a combination mechanism of guide plate 6, strip-shaped limiting holes 7, brush plate 8, and cleaning plate 9 for quick cleaning of the filter screen 4. During the process, the cleaning plate 9 can move smoothly along the inner wall of the strip-shaped limiting hole 7, which facilitates deep cleaning of the inside and surrounding area of ​​the filter screen 4 and effectively avoids the problem of reduced filtration efficiency caused by the accumulation of impurities. The disassembly and installation of the cover 13 is also simple, thanks to the application of the sealing gasket 15. The sealing gasket 15 is made of high-quality rubber material and has good deformation ability and sealing performance. It not only ensures the tightness of the cover 13 when closed to prevent sewage leakage, but also can be easily deformed when needed, so that users can easily disassemble the cover 13 without damaging the box body and carry out necessary inspection or maintenance work. Together, they form a sewage treatment system that is both efficient and easy to maintain. Example 2

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, an inclined plate 10 is fixedly connected inside the treatment tank 1, with the bottom of the inclined plate 10 closely attached to the bottom of the treatment tank 1. Furthermore, the inclined plate 10 is installed around the drain pipe 11 at the bottom of the treatment tank 1, which can effectively guide the water accumulated at the bottom of the treatment tank 1 to one side of the treatment tank 1, thereby ensuring smooth water discharge and greatly reducing the possibility of water accumulating at the four corners of the bottom of the treatment tank 1. This not only improves drainage efficiency but also prevents bacterial growth and odor problems caused by water accumulation, resulting in a significant improvement in the hygiene of the entire treatment system.

[0026] In a preferred embodiment, a drain pipe 11 is fixedly connected to one side of the treatment tank 1, and a gate 12 is movably installed above the drain pipe 11. The drain pipe 11 passes through one side of the treatment tank 1 and extends into the interior of the treatment tank 1. Furthermore, the drain pipe 11 is firmly connected to one side of the treatment tank 1 to ensure that the water at the bottom of the treatment tank 1 can be discharged smoothly, avoiding water accumulation. The gate 12 is movably installed above the drain pipe 11, allowing the user to control the drainage flow rate. This satisfies the different drainage requirements of different treatment stages and ensures the flexibility and controllability of the drainage process.

[0027] In a preferred embodiment, a positioning sleeve 14 is fixedly connected to the bottom of each of the tank covers 13. The positioning sleeve 14 is located directly above the guide rod 3 and is fitted onto the top of the guide rod 3. Furthermore, in order to ensure that the tank cover 13 can be accurately installed on the top of the guide rod 3, the positioning sleeve 14 is provided. This not only serves to securely fit the tank cover 13 onto the guide rod 3, but also effectively avoids the possibility of the tank cover 13 tilting during installation, thereby ensuring the stability and sealing of the treatment tank 1 structure and providing a solid hardware foundation for sewage treatment.

[0028] In a preferred embodiment, positioning plates 16 are fixedly connected to the edges of both the processing box 1 and the box cover 13, and pins 17 are fixedly connected to the top of the positioning plates 16. Furthermore, positioning plates 16 are fixedly connected at the overlapping positions of the processing box 1 and the box cover 13, which enhances the connection stability between the two. By using pins 17 to pass through the positioning plates 16, the processing box 1 and the box cover 13 are firmly positioned. Four positioning plates 16 are set and evenly distributed around the overlapping area, which greatly improves the overall positioning stability and ensures that the box cover 13 is stable and does not shake during the processing.

[0029] In a preferred embodiment, a water inlet pipe 18 is fixedly connected to the top of the cover 13. The water inlet pipe 18 penetrates the cover 13 and extends into the interior of the treatment tank 1. The bottom of the water inlet pipe 18 is located directly above the filter screen 4. Furthermore, in order to efficiently introduce external sewage into the treatment system, a water inlet pipe 18 is provided. This water inlet pipe 18 penetrates the top of the cover 13 and extends directly into the interior of the treatment tank 1, which greatly simplifies the operation process, allowing users to easily inject sewage directly into the treatment tank 1, improving work efficiency and maintaining a clean treatment environment.

[0030] The working process of this utility model is as follows: In use, firstly, wastewater enters the treatment tank 1 through the inlet pipe 18. After being filtered by the filter screen 4 inside the treatment tank 1, impurities are trapped on the surface of the filter screen 4, thus filtering impurities from the wastewater and ensuring wastewater filtration efficiency. The frame structure increases the cleaning area, allowing for quick cleaning of the inner side of the filter tank. Next, when cleaning impurities above the filter screen 4, the guide plate 6, the strip-shaped limiting hole 7, the brush plate 8, and the cleaning plate 9 work together. The cleaning plate 9 moves along the inner wall of the strip-shaped limiting hole 7, facilitating cleaning of the inside of the filter screen 4. When the tank cover 1 is closed… When the cover 13 is placed on top of the treatment tank 1, the positioning sleeve 14 is placed on top of the positioning groove 2. The sealing gasket 15 is made of rubber material and has a deformation function, which facilitates the smooth removal of the cover 13. Finally, the treatment tank 1 and the cover 13 are overlapped, and the pin 17 is installed inside the positioning plate 16. This ensures the tightness of the cover 13 when it is closed, preventing sewage leakage, and also allows it to be easily deformed when needed. This allows users to easily remove the cover 13 without damaging the tank body, perform necessary inspections or maintenance, solve the problem of impurity accumulation, and ensure the continuous and efficient operation of the sewage treatment equipment.
