It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. The most common component in wastewater treatment is the filtration system. Currently, most filters are disposable and are disposed of as waste after being removed from the machine. Therefore, there is a need for a device that can automatically clean and replace the filter.

[0003] Currently, multi-stage high-efficiency filtration devices for wastewater treatment are mostly disassembled manually or by machine, so they need to be disassembled and replaced every once in a while. During the disassembly process, the filtration task cannot be performed. Therefore, there is an urgent need in the market to develop a multi-stage high-efficiency filtration device for wastewater treatment that can automatically switch and clean the filter screen to help people solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage high-efficiency filtration device for sewage treatment, which has the function of automatically switching and cleaning the filter screen, thus solving the problem that the filter cannot be filtered when people disassemble it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage high-efficiency filtration device for sewage treatment, comprising an inlet tank, a first filtration tank, a second filtration tank, a third filtration tank, a fourth filtration tank, a fifth filtration tank, and an outlet fixing plate. Two filter screen frame slots are provided through the front and rear ends of the first, second, third, fourth, and fifth filtration tanks. A layered filtration and cleaning unit is provided at the junction of the first, second, third, fourth, and fifth filtration tanks. Each layered filtration and cleaning unit includes a filter screen moving component, a filter screen cleaning component, a filter screen frame, and a filter screen. The filter screen is fixed inside the filter screen frame. The filter screen moving component, filter screen frame, and filter screen cleaning component are arranged from front to back.

[0006] Preferably, the filter moving assembly includes a filter moving motor, which is installed at the lower end of the front end of the first, second, third, fourth, and fifth filter tanks along the outer side of the filter frame groove. Transmission gears are installed at the upper and lower ends of the front end of the first, second, third, fourth, and fifth filter tanks along the outer side of the filter frame groove. One of the transmission gears is connected to the output shaft of the filter moving motor. A transmission belt meshes with both transmission gears externally. Moving gears are coaxially connected to the transmission gears. Racks are meshed with the lower ends of both moving gears. The rear ends of both racks are connected to the filter frame. A gear fixing plate is provided on the outer side of the upper transmission gear.

[0007] Preferably, the filter cleaning assembly includes an upper fixing plate for the cleaning assembly, which is installed at the upper end of the rear end of the first, second, third, fourth, and fifth filter tanks along the filter frame groove. A lower fixing plate for the cleaning assembly is installed at the lower end of the rear end of the first, second, third, fourth, and fifth filter tanks along the filter frame groove. A cleaning assembly fixing frame is fixed on both sides of the rear end between the upper and lower fixing plates of the cleaning assembly.

[0008] Preferably, limit posts are provided on both sides of the rear end of the cleaning component fixing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a layered filtration and cleaning unit is installed in each filtration pool. When the filter screen is dirty, the filter screen can be moved to the filter screen cleaning unit for cleaning by the filter screen moving component. While the first layer of filter screen is being cleaned, the second layer of filter screen can still perform the filtration task. This can reduce the cost of manual disassembly and solve the problem that the filtration device cannot be used when the mechanical disassembly task is performed.

[0014] 2. In this utility model, when cleaning the filter screen, water is input through the main water pipe and sprayed through the branch water pipe. The moving motor and rotating motor of the cleaning component are started, and the cleaning roller rotates and moves up and down. Accompanied by the flushing of water, the dirt is washed off the filter screen, thereby reducing or eliminating manual cleaning.

[0015] 3. The core focus of this utility model is the layered filtration and cleaning unit, which can be set up with multiple filtration tanks according to the needs of sewage treatment. This allows for timely processing when targeted filtration tasks are carried out, rather than the filtration device being irreplaceable once it is manufactured, thus giving the device greater flexibility.

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides an embodiment of a multi-stage high-efficiency filtration device for sewage treatment, comprising an inlet tank 1, a first filter tank 2, a second filter tank 3, a third filter tank 4, a fourth filter tank 5, a fifth filter tank 6, and an outlet fixing plate 9. Two filter screen frame grooves 15 are provided through the front and rear ends of the first filter tank 2, second filter tank 3, third filter tank 4, fourth filter tank 5, and fifth filter tank 6. Layered filtration and cleaning units 12 are provided at the junctions of the first filter tank 2, second filter tank 3, third filter tank 4, fourth filter tank 5, and fifth filter tank 6. Each layered filtration and cleaning unit 12 includes a filter screen moving component 13, a filter screen cleaning component 14, a filter screen frame 16, and a filter screen 17. The filter screen 17 is fixed inside the filter screen frame 16. The filter screen moving component 13, filter screen frame 16, and filter screen cleaning component 14 are arranged from front to back. During use, the filter screen moving component 13 can be controlled to move the filter screen frame 16 within the filter screen frame groove 15.

[0025] Furthermore, the filter screen moving assembly 13 includes a filter screen moving motor 18, which is installed at the lower end of the front end of the first filter tank 2, the second filter tank 3, the third filter tank 4, the fourth filter tank 5, and the fifth filter tank 6 along the outer side of the filter screen frame groove 15. Transmission gears 19 are installed at the upper and lower ends of the front end of the first filter tank 2, the second filter tank 3, the third filter tank 4, the fourth filter tank 5, and the fifth filter tank 6 along the outer side of the filter screen frame groove 15. One of the transmission gears 19 is connected to the output shaft end of the filter screen moving motor 18, and the two transmission gears 19 mesh externally. The filter is connected by a transmission belt 20, and a transmission gear 19 is coaxially connected to a moving gear 21. The lower ends of the two moving gears 21 are meshed with racks 22, and the rear ends of the two racks 22 are connected to the filter frame 16. A gear fixing plate 23 is provided on the outside of the upper transmission gear 19. When the filter moving motor 18 is started, the rotating shaft rotates, driving the lower transmission gear 19 and the moving gear 21 to rotate. The two transmission gears 19 rotate together through the transmission belt 20. The rotation of the upper transmission gear 19 is coaxially linked with the upper moving gear 21, thereby controlling the movement of the two racks 22.

[0026] Furthermore, the filter cleaning assembly 14 includes an upper fixing plate 24, which is installed at the upper end of the rear end of the first filter tank 2, the second filter tank 3, the third filter tank 4, the fourth filter tank 5, and the fifth filter tank 6 along the filter frame groove 15. A lower fixing plate 25 is installed at the lower end of the rear end of the first filter tank 2, the second filter tank 3, the third filter tank 4, the fourth filter tank 5, and the fifth filter tank 6 along the filter frame groove 15. A cleaning assembly fixing frame 26 is fixed on both sides of the rear end between the upper fixing plate 24 and the lower fixing plate 25. The position of the filter cleaning assembly 14 is fixed by the upper fixing plate 24, the lower fixing plate 25, and the fixing frame 26 to prevent the assembly from failing to work properly due to insecure fixing during operation.

[0027] Furthermore, limit posts 30 are provided on both sides of the rear end of the cleaning component fixing frame 26. A cleaning component moving motor 27 is installed on the upper end of the cleaning component upper fixing plate 24 along the upper end of the cleaning component fixing frame 26. A threaded post 28 is installed inside the cleaning component fixing frame 26 along the output shaft end of the cleaning component moving motor 27. The two threaded posts 28 are externally threaded to the upper and lower moving posts 31. A vertical limiting sliding plate 29 is provided inside the cleaning component fixing frame 26 along the outside of the threaded post 28 and the upper and lower moving posts 31. The vertical limiting sliding plate 29 is fixed to the upper and lower moving posts 31. When the cleaning component moving motor 27 starts, the output shaft rotates the threaded post 28. The threaded post 28 rotates and drives the upper and lower moving posts 31 to rotate. However, because the vertical limiting sliding plate 29 is fixed on one side of the upper and lower moving posts 31 and is fixed to the upper and lower moving posts 31, the upper and lower moving posts 31 are restricted to moving only up and down.

[0028] Furthermore, a rotating wheel fixing frame 34 is fixed at the front end of the upper fixing plate 24 and the lower fixing plate 25 of the cleaning component along one side of the filter screen frame groove 15. The rotating wheel fixing frame 34 is provided with a vertically moving rotating wheel 35. When controlling the vertical movement, the vertically moving rotating wheel 35 moves and is confined within the rotating wheel fixing frame 34. A cleaning component rotation motor 32 is installed at the upper end of the vertical limiting sliding plate 29. A cleaning roller 33 is installed at the output shaft end of the cleaning component rotation motor 32. The intermediate shaft of the cleaning roller 33 is connected to the vertically moving rotating wheel 35 through a bearing. When the cleaning component rotation motor 32 starts, the output shaft rotates to drive the cleaning roller 33 to rotate and clean the garbage located on the filter screen 17.

[0029] Furthermore, water distribution pipes 37 are installed at equal intervals from front to back along the upper end of the cleaning roller 33 on the fixed plate 24 of the cleaning component. The other ends of several water distribution pipes 37 on each side are connected to the main water pipe 36. The main water pipe 36 inputs water flow and opens the water distribution pipes 37 for spraying. When the filter screen 17 on any side is being cleaned, the water distribution pipe 37 on that side is opened for operation.

[0030] Furthermore, an inlet 7 is provided through the upper outer side of the inlet pool 1, through which sewage is input. An outlet 8 is provided through the lower outer side of the outlet fixing plate 9, through which filtered sewage is output. An inlet fixing frame 10 is provided inside the inlet pool 1 along the outlet end of the inlet 7. A winding roller 11 is rotatably connected to the inlet fixing frame 10. When sewage enters from the inlet 7, the water flow drives the winding roller 11 to rotate, winding the thin strips of garbage.

[0031] Working principle: During use, sewage enters the inlet pool 1 through inlet 7, and the water flow drives the winding drum 11 to rotate, thus winding the thin strips of garbage onto the winding drum 11 for preliminary treatment. After the sewage enters the inlet pool 1, it flows along the inlet pool 1. When the sewage enters the first filter pool 2, the second filter pool 3, the third filter pool 4, the fourth filter pool 5, and the fifth filter pool 6 in sequence, the sewage passes through the filter screen 17, which gradually cleans and filters the dirt. After cleaning and filtration, the treated sewage is discharged from the outlet 8. When the garbage on the filter screen 17 is too heavy, the sewage input is stopped, and the layered filtration and cleaning unit 12 is activated. The filter screen moving motor 18 on the filter screen moving assembly 13 drives the lower transmission gear 19 to rotate. The two transmission gears 19 rotate together through the transmission belt 20. Each transmission gear 19 rotates coaxially with two moving gears 21, driving two racks 22 to move, thereby controlling the movement of the dirty filter screen 17 from the filter screen frame groove 15 into the filter screen cleaning assembly 14. At the same time, another filter screen 17 can be moved from the filter screen cleaning assembly 14 into the filter tank through the filter screen moving assembly 13 for filtration. When the filter screen 17 is in the filter screen cleaning assembly 14, water flow is input through the main water pipe 36, and clean water is sprayed out from the water distribution pipe 37 for rinsing. The cleaning assembly rotation motor 32 drives the cleaning roller 33 to rotate. The cleaning assembly moving motor 27 drives the threaded column 28 to rotate. The rotation of the threaded column 28 controls the up and down moving column 31 to move up and down, so that the rotating cleaning roller 33 washes the filter screen 17 from top to bottom with the water flow.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
