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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-4The device shown is a decontamination device for eel farming, comprising a feeding cylinder 1 for conveying materials during the eel farming process. Its cylindrical structure ensures stable material transport within the cylinder, preventing spillage. An output cylinder 2 is detachably connected to the outer side of the feeding cylinder 1, allowing the processed material to be discharged. The detachable design facilitates subsequent cleaning and maintenance. A filter plate 19 is detachably connected to the inner wall of the feeding cylinder 1, initially intercepting larger impurities in the material. Its detachable nature allows for regular cleaning of filtered impurities, ensuring effective filtration. A guide plate 13 is fixedly connected to the inner wall of the feeding cylinder 1, guiding the material to flow in a specific direction within the cylinder, ensuring smoother flow and preventing material accumulation or obstruction. An impurity filtration assembly is located on the outer side of the feeding cylinder 1, including a discharge port on the outer side of the cylinder to discharge filtered impurities, separating them from the material. A collection frame 3, adapted to the discharge port, is detachably connected to the outside of the conveying cylinder 1. The collection frame 3 is used to collect impurities discharged from the discharge port, and its detachable design facilitates centralized processing of the collected impurities. A baffle 18 is provided on the outside of the collection frame 3 to prevent impurities in the collection frame 3 from spilling out during device operation. Multiple blocking blocks 20 are fixedly connected to the inner wall side of the collection frame 3. The sides of the blocking blocks 20 are inclined, which can further block and guide the impurities, allowing them to remain more smoothly in the collection frame 3. A screening assembly is provided inside the output cylinder 2. The screening assembly includes a first filter plate 15, a second filter plate 16, and a third filter plate 17, which are sequentially arranged on the inner wall side of the output cylinder 2. The diameter of the filter holes in the first filter plate 15, the second filter plate 16, and the third filter plate 17 decreases sequentially. The first filter plate 15 filters out larger impurities in the material, the second filter plate 16 further filters out slightly smaller impurities, and the third filter plate 17 filters out even smaller impurities. Through three-stage filtration, precise separation of impurities of different sizes in the material is achieved, ensuring the purity of the output material. A common rotating rod 12 is installed on the outer side of each of the first, second, and third filter plates 17. The rotating rod 12 drives the scraper 21, fixed rod 10, and other components to rotate. Multiple scrapers 21 are fixedly connected to the outer side of the rotating rod 12. Driven by the rotating rod 12, the scrapers 21 scrape off impurities adhering to the first, second, and third filter plates 15, preventing filter pore blockage and ensuring filtration efficiency. A fixed rod 10 is fixedly connected to the outer side of the rotating rod 12. A rotating ring 9 is fixedly connected to the end of the fixed rod 10 away from the rotating rod 12. The rotating ring 9 transmits power, transferring the rotation of the rotating rod 12 to the gear teeth 11. Multiple gear teeth 11 are fixedly connected to the outer side of the rotating ring 9. The gear teeth 11 mesh with the gear 8, thereby realizing the rotation of the rotating rod 12. A motor 7 is fixedly connected to the outer side of the output cylinder 2, and the motor 7 provides power to the entire screening assembly.The output end of the motor 7 is fixedly connected to a gear 8, which meshes with the gear teeth 11. Through gear transmission, the power of the motor 7 is transmitted to the rotating rod 12, which drives the rotating rod 12 to rotate, thereby realizing the cleaning of the filter plate by the scraper 21 and the screening of materials.

[0024] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a fixing block 4 is fixedly connected to the outer side of the baffle 18. The fixing block 4 is connected to the outer side of the collection frame 3 by bolts 5. Both the fixing block 4 and the collection frame 3 have threaded holes that are compatible with the bolts 5 on their outer sides. By tightening the bolts 5, the fixing block 4 and the collection frame 3 can be tightly fitted together, so as to achieve a stable installation of the baffle 18 and prevent it from shifting or shaking during operation. A microbubble generator 6 is provided on the outer side of the output cylinder 2. Multiple output tubes 14 are fixedly connected to multiple output ends of the microbubble generator 6. The multiple output tubes 14 extend to the space between the filter plate 19 and the first filter plate 15, and between the first filter plate 15, the second filter plate 16 and the third filter plate 17, respectively. The microbubble generator 6 is used to generate a large number of microbubbles. These microbubbles are transported to the area between the filter plates through the output pipe 14. The microbubbles can attach to the impurity particles, increase their buoyancy, and accelerate the floating process of the impurities, thereby improving the filtration efficiency. At the same time, the microbubbles can also wash the surface of the filter plates, reduce the clogging of the filter plates, and extend their service life.

[0025] The working principle of this utility model is as follows: Aquaculture water is introduced into the feed cylinder 1. The filter plate 19 performs initial filtration of the aquaculture water. The guide plate 13 guides the aquaculture water and moves along its spiral trajectory, thus obtaining a tangential velocity around the axis of the feed cylinder 1. Impurities are filtered out and simultaneously thrown into the collection frame 3 for collection. Multiple blocking blocks 20 obstruct impurities. Through the coordinated arrangement of the first filter plate 15, the second filter plate 16, and the third filter plate 17, the aquaculture water undergoes multiple, step-like filtrations. The motor 7 drives the gear 8 to rotate, which in turn drives the rotating ring 9, the fixed rod 10, the rotating rod 12, and the scraper 21 to rotate, cleaning the surfaces of the first filter plate 15, the second filter plate 16, and the third filter plate 17, reducing impurity blockage. The microbubble generator 6 generates a large number of microbubbles through the output pipe 14, improving the filtration effect.

[0026] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
