[0002] Phosphorus is one of the main causes of eutrophication in water bodies, and efficient phosphorus removal is crucial for protecting the aquatic environment. In wastewater treatment, landscape water purification, and other fields, reliable phosphorus removal filtration devices are needed to reduce phosphorus content in water, ensure the ecological balance of aquatic bodies, and meet the practical needs of environmental protection and water resource recycling.

[0003] Existing phosphorus removal filtration devices mostly use a single filter tank with an internal filter media layer. During operation, the water to be filtered is directly passed into the tank, and phosphorus removal is achieved through the adsorption of the filter media. When the filter media becomes saturated, the device needs to be stopped, the tank cover opened, and the filter media removed for replacement or regeneration.

[0004] However, existing phosphorus removal filtration devices require a complete shutdown for filter media replacement, making uninterrupted filtration impossible. Furthermore, the traditional box opening structure is complex, and the operation is cumbersome and time-consuming, which affects processing efficiency and increases maintenance costs, making it difficult to meet the actual needs of efficient operation and maintenance and continuous processing. Therefore, a high-efficiency phosphorus removal filtration device is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency phosphorus removal filtration device, including a base 1. Two sets of housings 2 are fixedly connected to the top of the base 1. The two sets of housings 2 are symmetrically distributed, which can realize alternating filtration operations to ensure continuous operation of the device. A filter frame 3 is snapped into the inner wall of the housing 2. The filter frame 3 can hold phosphorus removal filter material. The snap-fit ​​method makes it easy to remove and replace the filter material later. The top of the filter frame 3 is in contact with a cover plate 4. The cover plate 4 has the dual function of sealing the housing 2 and supporting the internal components. Three sets of geared discs 5 are rotatably connected to the inner wall of the cover plate 4. The three sets of geared discs 5 are evenly distributed in a ring to ensure force balance and synchronous operation. The side wall of the cover plate 4 is in contact with the inner side wall of the housing 2.

[0034] Reference Figures 3-4 Each of the three sets of geared discs 5 has an arc groove 6 at its bottom. The arc groove 6 is designed with a smooth arc to guide the sliding of the slide rod 7. The slide rod 7 is slidably connected to the inner wall of the arc groove 6. The slide rod 7 can move radially along the arc groove 6. The bottom of the slide rod 7 is fixedly connected to a plug 8. The plug 8 moves with the slide rod 7 to achieve telescopic action. The inner side of the outer wall of the three sets of geared discs 5 is meshed with a rack 9. The linear movement of the rack 9 can drive the three sets of geared discs 5 to rotate synchronously. The side wall of the housing 2 has a slot 10. The size of the slot 10 matches the plug 8 to ensure the stability of the engagement. The top of the cover plate 4 is provided with a limit component. The limit component is used to fix the position of the cover plate 4 to prevent it from loosening during the operation of the device. The plug 8 is slidably connected to the inner wall of the cover plate 4 and is engaged with the inner wall of the slot 10. The rack 9 is slidably connected to the inner wall of the cover plate 4.

[0035] Reference Figure 1 , Figure 2 , Figure 6 The front and rear parts of the two sets of boxes 2 are connected by two sets of three-way pipes 18 respectively. The three-way pipes 18 enable the two sets of boxes 2 to operate in parallel, improving filtration efficiency. Valve plates 19 are rotatably connected to the inner walls on both sides of the three-way pipes 18. The valve plates 19 can be rotated to control the opening and closing of the pipeline. A valve switch 20 is fixedly connected to the top of the valve plate 19. The valve switch 20 allows the operator to manually control the rotation angle of the valve plate 19. The valve switch 20 is rotatably connected to the top inner wall of the three-way pipe 18.

[0036] Reference Figures 3-5The limiting assembly includes a rotating shaft 11, which is the core rotating component of the limiting assembly and provides support for subsequent components. The bottom of the rotating shaft 11 is fixedly connected to the top of a set of geared discs 5 in the middle. The synchronous rotation of the rotating shaft 11 and the geared discs 5 is achieved through the fixation with the geared discs 5. The inner wall of the rotating shaft 11 is elastically connected to a limiting guide block 13 through a limiting spring 12. The limiting guide block 13 is set as a square, which can slide up and down on the inner wall of the rotating shaft 11 and can also drive the rotating shaft 11 to rotate. A handle 14 is fixedly connected to the top of the limiting guide block 13, which facilitates the operator to rotate the rotating shaft 11. A limiting block 15 is fixedly connected to the bottom of the handle 14. The limiting block 15 is used to cooperate with the limiting groove 17 to achieve limiting. An upper extension platform 16 is fixedly connected to the top of the cover plate 4. The upper extension platform 16 is... The limiting assembly provides a base for installation and limiting, and prevents rainwater or other water sources from entering the internal transmission components. The top of the upper extension platform 16 has a limiting groove 17, which is arranged in a circular array to achieve multiple limiting positions. One end of the limiting spring 12 is fixedly connected to the inner wall of the rotating shaft 11, and the other end of the limiting spring 12 is fixedly connected to the bottom of the limiting guide block 13. Through the opposing pressing force between the limiting spring 12 and the rotating shaft 11, the limiting block 15 is always locked on the inner wall of the limiting groove 17 without being affected by external forces. The limiting guide block 13 is slidably connected to the inner wall of the rotating shaft 11. The bottom of the handle 14 is in contact with the top of the upper extension platform 16. The rotating shaft 11 is rotatably connected to the inner wall of the upper extension platform 16, and the limiting block 15 is locked on the inner wall of the limiting groove 17.

[0037] Working principle: Before the device is put into operation, the phosphorus removal filter material is filled into the filter frames 3 in the two sets of housings 2, and then the cover plate 4 is installed and fixed. During installation, pull the handle 14 upward. The handle 14 drives the limiting guide block 13 to compress the limiting spring 12, so that the bottom limiting block 15 disengages from the limiting groove 17 of the upper extension platform 16. Rotate the handle 14, and drive the rotating shaft 11 to rotate synchronously through the square limiting guide block 13. The bottom of the rotating shaft 11 is fixedly connected to the middle set of ring gear discs 5, thereby driving the ring gear discs 5 to rotate. Since the inner side of the outer wall of the three sets of ring gear discs 5 are all meshed with racks 9, the rotation of the middle ring gear disc 5 will drive the other two sets of ring gear discs 5 to rotate synchronously through the racks 9. When the ring gear disc 5 rotates, the arc groove 6 at its bottom rotates together. The sliding rod 7, which is slidably connected to the inner wall of the arc groove 6, moves radially along the smooth arc trajectory of the arc groove 6, driving the bottom insert 8 to extend outward. When the insert 8 is fully engaged with the inner wall of the slot 10 on the side wall of the housing 2, stop rotating the handle 14. After releasing, the limit spring 12 returns to its original position, pushing the limit guide block 13 and the handle 14 downwards, causing the limit block 15 to re-engage into the corresponding limit groove 17, thus completing the limiting and fixing of the cover plate 4. At this time, the device is in a sealed, ready-to-operate state. By adjusting the valve switch 20 at the top of the three-way pipe 18, the rotation angle of the valve plate 19 can be controlled, enabling the parallel operation of the two sets of housings 2. After the filtered water enters the two sets of housings 2 through the three-way pipe 18, it flows through the phosphorus removal filter media in the filter frame 3. The filter media adsorbs and removes phosphorus from the water. The filtered water is then discharged from the other set of three-way pipes 18, achieving efficient and continuous filtration.

[0038] When the filter media in one of the housings 2 needs to be replaced, turn the valve plate 19 through the valve switch 20 to close the corresponding pipeline channel of that housing 2, and switch to the other housing 2 to operate independently, ensuring that the device does not stop working. Then repeat the reverse operation of the cover plate 4 installation: pull the handle 14 upward to make the limit block 15 disengage from the limit groove 17, turn the handle 14 in the opposite direction to drive the three sets of ring tooth discs 5 to rotate in the opposite direction, and the slide rod 7 moves inward along the arc groove 6 trajectory, driving the insert block 8 to be pulled out from the slot 10, releasing the cover plate 4 from the housing 2. After removing the cover plate 4 upward, the filter frame 3 that is stuck to the inner wall of the housing 2 can be taken out, and the internal phosphorus removal filter media can be replaced. After the replacement is completed, reset the filter frame 3 and cover plate 4 according to the above installation steps, and then open the pipeline of that housing 2 through the valve switch 20 to restore the parallel operation of the two housings 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
