[0002] In the production of non-magnetic materials and the processing of powdered materials, removing magnetic impurities from raw materials is a crucial step in ensuring product quality. Currently, common demagnetizing equipment often uses fixed magnetic rods or static magnetic grids, requiring manual cleaning during operation, which disrupts production continuity. While rotary magnetic filters, developed later, can achieve cleaning without stopping the machine, their structure is often complex, making magnetic powder cleaning inconvenient, and there is a risk that adsorbed magnetic impurities may detach under prolonged material rinsing and re-mix with clean materials. Furthermore, although some integrated equipment combines stirring, demagnetizing, and sieving functions, reducing steps, it still fails to effectively achieve real-time, automatic stripping and collection of magnetic impurities in the demagnetizing stage, making it difficult to meet the demands of high-efficiency, high-quality continuous production. Therefore, there is an urgent need for a device that can achieve continuous, automatic impurity removal and effectively prevent secondary contamination by magnetic impurities. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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. Example 1

[0018] See Figure 2 A demagnetizing device includes a demagnetizing device housing 1, inside which a processing chamber is formed. The processing chamber is provided with a first bearing 18, a second bearing 19, a first magnetic ring 2, a second magnetic ring 7, a first isolation ring 8, and a second isolation ring 17. The first bearing 18 and the second bearing 19 are respectively used to drive the first magnetic ring 2 and the second magnetic ring 7 to rotate, so as to ensure that they can alternately perform continuous demagnetizing operation on particulate silicon.

[0019] The first magnetic ring 2 and the second magnetic ring 7 are associated with the first isolation ring 8 and the second isolation ring 17. The magnetic rings and the isolation rings can be set separately or fixedly connected. The magnetic rings themselves can be a complete circular structure or a non-complete structure occupying 3 / 4 to 4 / 5 of the circular structure to optimize the adsorption effect.

[0020] In the processing chamber, a first magnetic scraper 9 and a second magnetic scraper 16 are also provided, and the scraping ends of the magnetic scrapers are in contact with the outer surfaces of the first isolation ring 8 and the second isolation ring 17, respectively. When the magnetic particles in the particulate silicon are adsorbed onto the first isolation ring 8 and the second isolation ring 17, as the isolation rings rotate, the magnetic material in the particulate silicon is carried to the positions of the first magnetic scraper 9 and the second magnetic scraper 16 and scraped off, falling into the corresponding first collection box 10 and the second collection box 15.

[0021] Overall, the device achieves continuous demagnetization of solid particles or powders through the alternating rotation of the magnetic rings and the synergistic effect of the scraping plates. This effectively prevents magnetic materials from being washed away by particles over a long period of time and then re-mixed into the material, thus improving the impurity removal efficiency and material quality. At the same time, the structure is simple and maintenance is convenient. Example 2

[0022] See Figure 1 When the magnetic ring and the isolation ring are set separately, the first magnetic ring 2 and the second magnetic ring 7 are respectively installed inside the first isolation ring 8 and the second isolation ring 17. The first isolation ring 8 and the second isolation ring 17 are both cylindrical structures and made of polyurethane material, which effectively protects the magnetic ring from direct contact with the particulate silicon, prevents the magnetic ring from wearing, and allows the magnetic particles to be adsorbed on the surface of the isolation ring.

[0023] Both the first magnetic ring 2 and the second magnetic ring 7 have magnetic adsorption areas on their circumference. The ends of the magnetic adsorption areas correspond to the scraping ends of the first magnetic scraper 9 and the second magnetic scraper 16. When the isolation ring rotates, the adsorbed magnetic material is carried to the position of the magnetic scraper and scraped off, realizing continuous and automatic removal of magnetic impurities and preventing the magnetic material from being washed back by the material.

[0024] There are two design options for the magnetic rings: First, when the first magnetic ring 2 and the second magnetic ring 7 are complete permanent magnet rings, a continuous magnetic adsorption area is formed around their circumference. In this case, the first isolation ring 8 and the second isolation ring 17 rotate continuously, transporting the magnetic material adsorbed on their surfaces to the first scraper plate 9 and the second scraper plate 16 for scraping. Second, when the first magnetic ring 2 and the second magnetic ring 7 are not complete rings (for example, occupying 3 / 4 to 4 / 5 of the entire circumference), they rotate synchronously with the isolation rings, thus forming a periodically operating magnetic adsorption area. This adsorption area adsorbs magnetic impurities in the particulate silicon when rotating to the feeding section. When rotating to the scraper plate position away from the material, the magnetic impurities are scraped off. If an electromagnet is used, it can also be controlled by partitioning, de-energizing the area when rotating near the scraper plate, making it easier to remove impurities.

[0025] It should be noted that the first magnetic ring 2 and the second magnetic ring 7 can also be designed as one being a complete circular ring and the other being a non-complete circular ring.

[0026] In a further embodiment of this utility model, the upper part of the outer shell 1 of the demagnetizing device is connected to the inlet 5 and the inlet pipe 6, and the lower part is connected to the outlet 13 and the outlet pipe 14, so as to ensure that the material can smoothly enter and exit the processing chamber and realize continuous production.

[0027] The processing chamber is also equipped with a first baffle 3, a second baffle 4, a third baffle 11, and a fourth baffle 12. The first baffle 3 is connected to the inner wall of the processing chamber on one side and to the outer surface of the second isolation ring 17 on the other side; the second baffle 4 is connected to the inner wall of the processing chamber on one side and to the outer surface of the first isolation ring 8 on the other side; the third baffle 11 is connected to the inner wall of the processing chamber on one side and to the outer surface of the first collection box 10 on the other side; the fourth baffle 12 is connected to the inner wall of the processing chamber on one side and to the outer surface of the second collection box 15 on the other side. These baffles guide the flow of materials, prevent short circuits, and ensure that magnetic impurities are fully adsorbed and collected.

[0028] In a further embodiment of this utility model, the first collection box 10 and the second collection box 15 are detachably connected to the outer shell 1 of the demagnetizing device, which facilitates regular cleaning and replacement. The collection boxes are respectively provided with fixed magnetic blocks, which can further adsorb and fix the scraped magnetic material, making it convenient to judge and analyze the magnetic impurities in the whole batch of materials. Example 3

[0029] join Figure 1 When the magnetic ring and the isolation ring are fixedly connected, the first magnetic ring 2 and the second magnetic ring 7 are integrated with the first isolation ring 8 and the second isolation ring 17. The rest of the structure is the same as in Embodiment 2, and will not be described again here.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
