[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: an influent wastewater filtration device for a sewage treatment plant, comprising a housing 1, a guide rail 2 fixedly connected to one side of the housing 1, a fixed frame 3 slidably connected to one side of the guide rail 2, a first motor 4 fixedly connected to one side of the housing 1, a threaded rod 5 fixedly connected to the output shaft of the first motor 4, a fixing block 6 provided on the outer surface of the threaded rod 5, one side of the fixing block 6 fixedly connected to one side of the fixed frame 3, an electric push rod 7 fixedly connected to the lower part of the fixed frame 3, and a connecting block 8 fixedly connected to the lower part of the electric push rod 7. An adjustment groove is provided on one side of the box 1. A second spring 9 is fixedly connected inside the adjustment groove. An adjustment block 10 that is slidably connected inside the adjustment groove is fixedly connected to one end of the second spring 9. A push plate 11 is fixedly connected to one side of the adjustment block 10. A guide plate 12 is fixedly connected inside the box 1. A fixed cylinder 13 is fixedly connected to the inner side wall of the box 1. A first spring 14 is fixedly connected inside the fixed cylinder 13. A connecting rod 15 that is slidably connected inside the fixed cylinder 13 is fixedly connected to one side of the first spring 14. An extrusion plate 16 is fixedly connected to one side of the connecting rod 15.

[0025] Specifically, a controller is installed on one side of the housing 1. The controller is an industrial-grade programmable logic controller (PLC) and is connected to the first motor 4, electric push rod 7, first hydraulic rod 23, and second hydraulic rod 27 via a digital input / output module. The controller has a built-in program to coordinate the movement of the fixed frame 3, the pressure adjustment of the push plate 11, and the opening and closing of the baffle. Multiple position switches are provided on one side of the guide rail 2 to facilitate the adjustment of the position of the fixed frame 3. The position switches are inductive proximity switches installed at designated positions on the guide rail 2 to provide feedback on the real-time position of the fixed frame 3. An adjustment switch is provided inside the adjustment slot to control the lifting and lowering of the hydraulic rod, so that the push plate 11 can maintain a certain downward pressure when moving on the guide plate 12. The first motor 4 drives the fixed frame 3 to move back and forth along the guide rail 2 via the threaded rod 5. The guide rail 2 drives the push plate 11 to push the deposited garbage towards the guide plate 12, and the garbage is squeezed between the push plate 16 and the compression plate 16 by the elastic force of the first spring 14, reducing the moisture content of the garbage and facilitating garbage removal.

[0026] Please see Figure 1 and Figure 4 A support block 17 is fixedly connected to the inner wall of the box 1. A sliding groove is provided on one side of the support block 17. A filter screen 18 is slidably connected inside the sliding groove. A fixing column 19 is fixedly connected above the support block 17.

[0027] Specifically, there are two filter screens 18, with the filter screen 18 closer to the outlet having a higher filtration precision to minimize debris in the wastewater.

[0028] Please see Figure 4 A support plate 20 is fixedly connected to one side of the filter screen 18, and a connecting rope 21 is fixedly connected to the top of the support plate 20. A pull ring 22 is fixedly connected to one end of the connecting rope 21.

[0029] Specifically, the pull ring 22 and the connecting rope 21 make it easy to remove the filter screen 18 and then move it to one side of the box 1 for easy replacement of the filter screen 18.

[0030] Please see Figure 2 A first hydraulic rod 23 is fixedly connected to the top of the fixing frame 3. One end of the first hydraulic rod 23 is fixedly connected to a mounting plate 24, and a hook 25 is fixedly connected to one side of the mounting plate 24.

[0031] Specifically, the pull ring 22 is hung on the hook 25, and the first hydraulic rod 23 drives the filter screen 18 to rise through the mounting plate 24, raising the filter screen 18 out of the groove of the support block 17.

[0032] Please see Figure 1A water inlet is provided on one side of the housing 1, and a water inlet pipe is provided on one side of the water inlet. A water outlet is provided on the side of the housing 1 near the filter screen 18.

[0033] Specifically, wastewater enters the tank 1 through the inlet pipe, undergoes preliminary filtration, and is discharged from the outlet.

[0034] Please see Figure 2 The guide plate 12 has a drop opening on one side, and a baffle 26 is rotatably connected to one side of the drop opening. A second hydraulic rod 27 is hinged to the bottom of the baffle 26, and one end of the second hydraulic rod 27 is hinged to the inner wall of the box 1.

[0035] Specifically, the inner wall of the housing 1 is equipped with corresponding control switches, including waterproof push-button switches and a human-machine interface, which support manual and automatic mode switching. When the squeezing plate 16 touches the corresponding control switch, the second hydraulic rod 27 drives the baffle 26 to rotate. The garbage, after being squeezed to remove moisture, falls into the collection box through the drop outlet, facilitating subsequent garbage cleaning.

[0036] During use, wastewater enters the tank 1 through the inlet, is filtered by the filter screen 18, and is discharged through the outlet. The filter screen 18 filters out the garbage. The first motor 4 drives the fixed block 6 to move via the threaded rod 5. The fixed block 6 drives the push plate 11 to the appropriate position via the fixed frame 3. Then, the electric push rod 7 drives the push plate 11 to move down via the connecting block 8 and the adjusting block 10, so that the push plate 11 contacts the inner bottom wall of the tank 1. Then, the first motor 4 drives the fixed frame 3 to move via the threaded rod 5, which in turn drives the push plate 11 to move. The push plate 11 pushes the garbage to one side, and the garbage passes through the guide. Plate 12 contacts the squeezing plate 16, causing the squeezing plate 16 to be squeezed under the elastic force of the first spring 14, removing most of the moisture from the garbage. Then, the second hydraulic rod 27 drives the baffle 26 to rotate, and the garbage falls into the collection frame 28 under the action of gravity, which is convenient for subsequent cleaning. After the filter screen 18 has been used for a period of time, the first motor 4 moves the fixing frame 3 to a suitable position, and then the pull ring 22 is hung on the hook 25. The first hydraulic rod 23 drives the filter screen 18 to move upward through the mounting plate 24, so that the filter screen 18 comes out of the box 1, which is convenient for cleaning and replacement of the filter screen 18.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
