[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-5 As shown, an energy-saving multi-stage filtration sewage treatment device includes a housing 1, a drain pipe 2, filter plates 3, discharge hoppers 4, a cover plate 5, and a sealing strip 6. The bottom of the housing 1 is fixedly connected to the drain pipe 2, and multiple filter plates 3 are installed sequentially from top to bottom, arranged end to end and tilted downwards. The mesh size of each filter plate 3 increases progressively. Multiple discharge hoppers 4 are fixedly connected to the left and right sides of the housing 1. Each discharge hopper 4 is located at the bottom edge of each filter plate 3. Each filter plate 3 is inserted into the housing 1 front and back and can pass through the rear of the housing 1. The rear of the housing 1 is fixedly fastened to the cover plate 5 by fasteners, which are known prior art, such as bolts. The front end of the cover plate 5 is provided with a closed-loop sealing strip 6, which is sealed and fitted to the rear end of the housing 1.

[0021] When in use, pour the wastewater into the right side of the box 1 from top to bottom. The wastewater will then be filtered through multiple filter plates 3. The liquid part will eventually be discharged through the drain pipe 2, while the solid part will be discharged through the discharge hopper 4. When it is necessary to clean or maintain the filter plates 3, remove the cover plate 5 and you can pull out any filter plate 3 without having to disassemble them in sequence, making cleaning and maintenance more convenient.

[0022] The housing 1 is fixed with multiple sets of support platforms 7, the same number as the filter plates 3. Two support platforms 7 form a group, and the two support platforms 7 in each group are fixed to the left and right ends of the inner wall of the housing 1, respectively. Each set of support platforms 7 supports the bottom ends of the left and right sides of each filter plate 3.

[0023] The housing 1 is also equipped with a cleaning mechanism. The housing 1 contains multiple sets of guide light rods 8, the same number as the filter plates 3. Two guide light rods 8 form a group, and the two guide light rods 8 in each group are fixed on the left and right sides of the housing 1 respectively. Each group of guide light rods 8 is located below the filter plates 3 and is arranged horizontally front and back. The cleaning mechanism includes a lower scraper 10 and a lower transmission frame 11. The housing 1 is slidably connected to the lower transmission frame 1. Multiple sets of vertical lower scrapers 10 are fixed from top to bottom at the rear of the lower transmission frame 11. The top of each set of lower scrapers 10 is flush with the bottom of the filter plates 3. Each set of lower scrapers 10 is slidably connected to each set of guide light rods 8. The front of the upper transmission frame 13 protrudes from the front side of the housing 1.

[0024] By manually pushing and pulling the lower transmission frame 11, the lower scraper 10 can move back and forth, thereby cleaning the bottom of each filter plate 3, which can reduce clogging and facilitate cleaning. On the other hand, the lower scraper 10 cooperates with the guide rod 8 and is flush with the bottom of the filter plate 3, which can help support the filter plate 3 and improve the support effect.

[0025] The cleaning mechanism also includes an upper support plate 12 and an upper transmission frame 13. The upper transmission frame 13 is slidably connected to the front and rear of the housing 1. Multiple sets of vertical upper support plates 12 are fixed from top to bottom at the rear of the upper transmission frame 13. Each upper support plate 12 has a continuous row of bristles 27 fixed at its bottom end. The bristles 27 at the bottom end of each upper support plate 12 are respectively attached to the top of each filter plate 3. The front of the upper transmission frame 13 protrudes from the front side of the housing 1.

[0026] Furthermore, by manually pushing and pulling the upper transmission frame 13, the upper support plate 12 can be moved back and forth, thereby using the brush bristles 27 to clean the top of the filter plate 3, thus improving the cleaning effect on the filter plate 3.

[0027] The number of lower scrapers 10 in each group shall not be less than two, and the number of upper support plates 12 in each group shall not be less than two. The lower scrapers 10 shall be vertically aligned and parallel to each other in front and back. The upper support plates 12 shall be vertically aligned and parallel to each other in front and back.

[0028] By limiting the number of upper support plates 12 and lower scrapers 10, the moving distance of the upper support plates 12 and lower scrapers 10 when cleaning the filter plate 3 can be reduced, thus achieving the effect of saving labor and energy.

[0029] The furthest distance between the lower scrapers 10 in each group is less than half the inner width of the box body 1, and the furthest distance between the upper support plates 12 in each group is less than half the inner width of the box body 1.

[0030] By limiting the spacing between the upper support plate 12 and the lower scraper 10, it can be ensured that the upper support plate 12 and the lower scraper 10 fully cover each filter plate 3 when they move back and forth, thereby ensuring the cleaning effect.

[0031] The cleaning mechanism also includes a cylinder 14, an upper support arm 15, a first support shaft 16, a receiving groove 17, a support base 18, a deflector plate 19, a second support shaft 20, a lower support arm 21, a third support shaft 22, a gear 23, a second rack 24, a first rack 25, and a planar spiral spring 26. The filter plate 3 at the top of the housing 1 is inclined to the lower left. A vertical cylinder 14 that runs vertically through the housing 1 is fixed to the upper right. The cylinder 14 is fixed with an upper support arm 15 and rotatably connected to a first support shaft 16 extending in the front-back direction. The right side of the cylinder 14 is fixedly connected to the receiving groove 17 and has a fixed support base 18. Multiple deflector plates 19 are fixed at equal angles around the circumference of the first support shaft 16. Each deflector plate 19 is located in the cylinder 14 and the receiving groove 17, respectively. The deflector plate on the right side of the first support shaft 16... 19 is located in the receiving groove 17. The upper support arm 15 is rotatably connected to the second support shaft 20. The front end of the box 1 is fixed to the lower support arm 21. The lower support arm 21 is rotatably connected to the third support shaft 22. The left side of the third support shaft 22 is coaxially fixed to the gear 23. The front part of the upper transmission frame 13 is fixed to the horizontal second rack 24. The front part of the lower transmission frame 11 is fixed to the horizontal first rack 25. The first rack 25 and the second rack 24 mesh with the upper and lower sides of the gear 23, respectively. The first support shaft 16 and the second support shaft 20, as well as the second support shaft 20 and the third support shaft 22, are connected by a transmission mechanism to achieve simultaneous rotation. The first support shaft 16 is coaxially fixed to the planar spiral spring 26. The outer peripheral end of the planar spiral spring 26 is fixed to the support seat 18.

[0032] Furthermore, during use, wastewater is poured into the cylinder 14. At this time, the wastewater impacts the actuating plate 19 on the left side of the first support shaft 16, causing the first support shaft 16 to overcome the elastic force of the planar spiral spring 26 and rotate counterclockwise. This, in turn, drives the second support shaft 20, the third support shaft 22, and the gear 23 to rotate through the transmission mechanism. After the wastewater is stopped being poured in, the first support shaft 16 returns to its original position under the elastic force of the planar spiral spring 26, causing the gear 23 to reverse. This achieves the forward and reverse rotation of the gear 23, which in turn causes the upper transmission frame 13 and the lower transmission frame 11 to move back and forth through the first rack 25 and the second rack 24. This allows for automatic cleaning using the upper support plate 12, the brush bristles 27, and the lower scraper 10, making the process more convenient, efficient, and energy-saving.

[0033] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
