[0002] Concentrated pig feed, as a core input in the pig farming industry chain, directly affects the growth efficiency, health status, and economic benefits of pigs. Concentrated pig feed is typically composed of a mixture of protein raw materials, minerals, vitamins, and additives. During raw material procurement, transportation, storage, and early processing, impurities such as stones, metal fragments, weeds, and moldy particles are easily introduced. Furthermore, due to differences in raw material grinding precision and material agglomeration during mixing, the processed concentrated feed often suffers from uneven particle size.

[0003] Existing drum filter devices typically have a single-cylinder filter inside, resulting in poor filtration efficiency and a single material movement trajectory, making it difficult to effectively separate some materials. In addition, the rotating filter cylinder is usually installed inside the device, which makes it inconvenient to maintain the filter cylinder and affects subsequent operations. Utility Model Content

[0030] Working principle: Before starting the device, first fix the barrel 1 on the horizontal working surface using the support leg 2, check the integrity of the screen holes of the inner filter cylinder 12 and the outer filter cylinder 14, as well as the rotation flexibility of the L-shaped ring plate 11 in the L-shaped ring groove 10, and at the same time confirm that the round cover 3 is securely connected to the barrel 1 via the first protrusion 4, the second protrusion 5, and bolts. The concentrated pig feed to be screened is introduced into the feeding arc cylinder 20 through the feeding funnel. With the help of the arc-shaped guiding structure of the feeding arc cylinder 20, the material falls evenly into the interior of the inner filter cylinder 12. When the drive motor 19 is started, its output end drives the rotating rod 18 to rotate synchronously. The rotating rod 18 drives the gear 17 fixed at its end to rotate. Since the gear 17 is meshed with the gear ring 16 near the end of both the inner filter cylinder 12 and the outer filter cylinder 14, and the outer filter cylinder 14 is rotatably connected to the bearing on the inner wall of the barrel 1 through the fixed ring plate 13, and the two ends of the inner filter cylinder 12 are rotatably connected to the round cover 3 and the bearing of the barrel 1 respectively, the rotation of the gear 17 synchronously drives the inner filter cylinder 12 and the outer filter cylinder 14 to rotate. During the rotation, the aperture of the inner filter cylinder 12 is larger than that of the outer filter cylinder 14. Large particles larger than the aperture of the inner filter cylinder 12 slide along the inner wall of the inner filter cylinder 12 under the action of centrifugal force and gravity, and finally fall from the end of the inner filter cylinder 12 into the discharge arc plate 21, where they are guided out. Medium-sized feed particles smaller than the aperture of the inner filter cylinder 12 but larger than the aperture of the outer filter cylinder 14 enter between the two cylinders through the screen holes of the inner filter cylinder 12. Under the limiting action of the annular baffle 15 and the rotational thrust of the outer filter cylinder 14, they move towards the fixed ring plate 13 and are finally discharged from the first discharge ring plate 22. Fine, qualified feed particles smaller than the aperture of the outer filter cylinder 14 pass through the screen holes of the outer filter cylinder 14 and fall into the bottom of the machine cylinder 1, where they gather along the inner wall of the machine cylinder 1 and are discharged from the second discharge ring plate 23. Throughout the process, the L-shaped ring plate 11 rotates synchronously with the filter cylinder within the L-shaped annular groove 10, providing sealing and support to prevent material leakage from the connection gap between the filter cylinder and the round cover 3 and the trapezoidal ring plate 9, thus achieving three-stage precise grading and screening.

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the drive motor 19 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
