[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a filtering device for processing chemical reagent additives, including a base 1, an outer wall of the base 1 is fixedly connected with a fixed plate 2, an outer wall of the fixed plate 2 is fixedly connected with a cylinder 3, a driving end of the cylinder 3 is fixedly connected with a rack 4, an outer wall of the rack 4 is slidably connected inside the base 1, a rotating shaft 6 is rotatably connected inside the base 1, one end of the rotating shaft 6 is fixedly connected with a half gear 5, the half gear 5 meshes with the rack 4, the other end of the rotating shaft 6 is fixedly connected with a connecting rod 7, an outer wall of the connecting rod 7 is fixedly connected with a filter box 8, a screen 27 is slidably connected inside the filter box 8, and a top plate assembly is arranged at the upper end inside the filter box 8.

[0024] Specifically, first, the auxiliary agent is injected into the interior of the filtration tank 8 through the hopper 11. At this stage, the auxiliary agent will first pass through the preliminary filtration of the screen 27. The main function of the screen 27 is to intercept large particle impurities in the auxiliary agent, ensuring that only smaller particles can continue to enter the next filtration stage. After the preliminary filtration, the auxiliary agent will enter the activated carbon filter plate 21 below the screen 27. Activated carbon has a strong adsorption capacity and can effectively remove impurities and odors in the auxiliary agent, ensuring the purity and stability of the auxiliary agent. Below the activated carbon filter plate 21 is the RO membrane filter plate 22. The RO membrane, that is, the reverse osmosis membrane, has extremely high filtration accuracy and can perform the final filtration of the auxiliary agent to ensure that the quality of the output auxiliary agent reaches the highest standard. After completing the above filtration steps, just turn the switch valve 26, and the auxiliary agent will be smoothly discharged through the discharge pipe 25. To prevent impurities from forming a sediment layer on the top surface of the filter screen, the device is also equipped with a filter screen rotation mechanism. The cylinder 3 is used to push the rack 4 back and forth, and the rack 4 drives the meshing half gear 5 to rotate, which in turn drives the rotating shaft 6 and the connecting rod 7 to rotate, causing the filtration tank 8 to rotate back and forth. This design ensures the uniform distribution of the auxiliary agent during the filtration process and improves the filtration effect.

[0025] Referring to Figures 2 - 4 , the top plate assembly includes the top cover 10. The outer wall of the top cover 10 is slidably connected to the upper end of the inner wall of the filtration tank 8. A bolt 9 is threadedly connected inside the top cover 10, and the outer wall of the bolt 9 passes through the interior of the filtration tank 8. The lower surface of the top cover 10 is fixedly connected to the connecting plate 20, and the lower surface of the connecting plate 20 is fixedly connected to the upper surface of the screen 27. A hopper 11 is fixedly connected inside the top cover 10, a handle 12 is fixedly connected to the upper surface of the top cover 10, a motor 13 is fixedly connected to the upper surface of the top cover 10, the output end of the motor 13 is fixedly connected to the rotating rod 14, a plurality of stirring blades 15 are fixedly connected to the outer wall of the rotating rod 14, a scraper 16 is fixedly connected to the bottom end of the rotating rod 14, and the lower surface of the scraper 16 is in contact with the upper surface of the screen 27. A sludge pump 17 is fixedly connected to the outer wall of the filtration tank 8, an extraction pipe 18 is fixedly connected to the input end of the sludge pump 17, the outer wall of the extraction pipe 18 is fixedly connected inside the filtration tank 8, and a delivery pipe 19 is fixedly connected to the output end of the sludge pump 17.

[0026] Specifically, at the same time, the motor 13 drives the rotating rod and the stirring blades 15 to rotate, causing the auxiliary agent to continuously rotate inside the filtration tank 8. This not only ensures the full contact between the auxiliary agent and the filtration material but also prevents impurities from covering the screen 27 and affecting the filtration effect through the continuous scraping of the scraper 16 on the upper surface of the screen 27. The sludge pump 17 sucks out the impurities through the extraction pipe 18 and discharges them through the delivery pipe 19. In this way, the impurities are effectively removed, ensuring the continuity and stability of the filtration process. When it is necessary to clean or replace the screen 27, just turn the bolt 9 to separate the top cover 10 from the filtration tank 8, and then the screen 27 can be easily removed from the interior of the filtration tank 8.

[0027] Reference Figure 3 As shown in Figure 3 , a sliding connection is provided below the interior of the filtration box 8 with an activated carbon filter plate 21. Below the activated carbon filter plate 21, an RO membrane filter plate 22 is provided. Sealing plates 23 are fixedly connected to the outer walls of both the activated carbon filter plate 21 and the RO membrane filter plate 22. A second handle 24 is fixedly connected to the outer wall of the sealing plate 23. A discharge pipe 25 is fixedly connected to the bottom end of the filtration box 8. A switch valve 26 is provided inside the discharge pipe 25.

[0028] Specifically, similarly, when the activated carbon filter plate 21 needs to be replaced, the sealing plate 23 is removed from the filtration box 8 by pulling the second handle 24, and then the activated carbon filter plate 21 and the RO membrane filter plate 22 can be cleaned and replaced.

[0029] Working principle: When the device needs to be used, first, the auxiliary agent is injected into the interior of the filtration box 8 through the hopper 11. The auxiliary agent is first preliminarily filtered by the sieve 27 to filter out large particle impurities in the auxiliary agent. Then, the activated carbon filter plate 21 below the sieve 27 adsorbs impurities and odors in the auxiliary agent. Next, the RO membrane filter plate 22 below the activated carbon filter plate 21 performs the final filtration of the auxiliary agent. Finally, the switch valve 26 is rotated, and the auxiliary agent is discharged through the discharge pipe 25. When it is necessary to prevent impurities from forming a sediment layer on the top surface of the filter screen, first, the cylinder 3 connected to the fixed plate 2 is started. The output end of the cylinder 3 pushes the rack 4 to move back and forth. The rack 4 drives the meshing semi-gear 5 to rotate. The semi-gear 5 drives the rotating shaft 6 and the connecting rod 7 to rotate. The connecting rod 7 drives the filtration box 8 to rotate back and forth. At the same time, the motor 13 is started to drive the rotating rod to rotate. The rotating rod drives the stirring blades 15 to rotate, continuously rotating the auxiliary agent. The rotation of the rotating rod drives the scraper 16 to continuously scrape on the upper surface of the sieve 27 to prevent impurities from covering the sieve 27 and affecting the filtration effect. At the same time, the sludge pump 17 is started to suck out the impurities through the extraction pipe 18 and then discharge them through the delivery pipe 19. By rotating the bolt 9, it is separated from the filtration box 8 and the top cover 10, facilitating the removal of the sieve 27 from the interior of the filtration box 8 for cleaning. When it is necessary to replace the activated carbon filter plate 21, the sealing plate 23 is removed from the interior of the filtration box 8 by pulling the second handle 24, and the activated carbon filter plate 21 and the RO membrane filter plate 22 connected to the sealing plate 23 are cleaned and replaced to improve the filtration effect.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
