[0001] This utility model relates to the field of screening equipment technology, specifically a suspended drum magnetic separator. Background Technology

[0002] In the field of waste lithium battery recycling, with the rapid development of industries such as electric vehicles and portable electronic devices, the number of waste lithium batteries has increased dramatically, making their effective recycling and resource reuse an urgent problem to be solved. Waste lithium batteries contain a large number of valuable metal elements, such as lithium, cobalt, and nickel, but they also pose potential environmental pollution risks. Therefore, in the process of recycling waste lithium batteries, fine screening and efficient magnetic separation of materials to separate magnetic impurities (such as iron shell fragments, magnetic screws, etc.) and non-magnetic materials with recycling value are key steps to improve recycling efficiency, ensure product quality, and reduce environmental pollution.

[0003] However, traditional magnetic separation equipment often faces numerous challenges when processing the screened materials after recycling waste lithium batteries. On the one hand, the crushed and screened products of waste lithium batteries contain a wide variety of materials with diverse particle sizes, placing higher demands on the adaptability and processing capacity of magnetic separation equipment. On the other hand, since waste lithium batteries contain a certain amount of magnetic impurities, if they cannot be effectively removed, it will directly affect the purity and recovery efficiency of subsequent extraction of valuable metals.

[0004] To address the aforementioned issues, it is particularly important to develop a suspended drum magnetic separator specifically designed for screening waste lithium batteries after recycling. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a suspended drum magnetic separator.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] like Figure 1-4As shown, a suspended drum magnetic separator includes a magnetic separator housing 1, a feed inlet 2 installed on the top of the magnetic separator housing, and an iron magnetic separator drum 5 rotatably installed inside the magnetic separator housing 1. Specifically, in this embodiment, the iron magnetic separator drum 5 is driven to rotate by a motor 7 and a transmission component. An iron outlet 4 and a material outlet 3 are respectively installed at the bottom of the magnetic separator housing corresponding to the two sides of the iron magnetic separator drum. A permanent magnet plate 6 is installed inside the magnetic separator housing corresponding to the material outlet. The permanent magnet plate and the iron magnetic separator drum form an adsorption zone. After the adsorbed material on the iron magnetic separator drum leaves the adsorption zone, it is discharged from the iron outlet.

[0029] The outer circumference of the iron magnetic separation drum 5 is uniformly equipped with baffles 10 along the axial direction, forming a storage trough between adjacent baffles 10. This design can more effectively control the flow and distribution of materials on the drum. The presence of the storage trough allows the material to be more evenly subjected to the magnetic field during drum rotation, increasing the contact time and area between the magnetic material and the drum, thereby improving the efficiency and accuracy of magnetic separation. At the same time, the storage trough can also prevent excessive accumulation or slippage of materials on the drum to a certain extent, enhancing the stability of the magnetic separation process.

[0030] In a preferred embodiment, a suspension flange is installed at the feed inlet on the top of the magnetic separator housing, allowing the entire magnetic separator to be easily suspended and installed at the discharge outlet of the primary screening equipment or other required locations. This installation method not only saves floor space but also simplifies the installation process, reducing installation difficulty and cost. Furthermore, the suspension flange has a certain degree of adjustability, allowing for fine-tuning as needed to ensure proper connection and coordinated operation between the magnetic separator and the primary screening equipment.

[0031] In a preferred embodiment, an iron discharge hopper 12 and a material discharge hopper 11 are respectively installed on the magnetic separator housing 1 at the iron discharge port and material discharge port positions. This design enables more efficient collection and processing of the magnetically separated material. The presence of the iron discharge hopper and the material discharge hopper allows magnetic and non-magnetic materials to be guided to different collection containers, avoiding material mixing and cross-contamination. Simultaneously, the iron discharge hopper and the material discharge hopper also have a certain buffering and guiding effect, which can slow down the falling speed and impact force of the material, protect the collection container from damage, and reduce the generation of dust and noise.

[0032] In a preferred embodiment, the permanent magnet plate 6 is an arc-shaped plate, and there are two of them. The two magnet plates are installed opposite each other on both sides of the iron magnetic separation drum. This design facilitates the natural diversion and guidance of materials during the separation process. After the magnetic and non-magnetic materials are separated on the drum, they will flow along different paths to their respective outlets. Since the iron outlet and the material outlet are distributed in a figure-eight shape, the crossing and confusion of materials at the outlet can be avoided more effectively, improving the clarity and accuracy of material separation.

[0033] In a preferred embodiment, a guide plate 8 and a baffle plate 9 are installed inside the magnetic separator housing 1, corresponding to the feed inlet. The guide plate 8 is installed facing the ferrous magnetic separator drum, and the lower end of the baffle plate 9 extends to the side wall of the ferrous magnetic separator drum. This design guides the material into the magnetic separation area at the optimal angle and speed, ensuring uniform distribution and thorough magnetic separation of the material on the drum. The presence of the baffle plate also prevents the material from directly impacting the drum side wall or splashing out of the magnetic separation area, further improving the stability and efficiency of magnetic separation.

[0034] In a preferred embodiment, the iron outlet and the material outlet on the magnetic separator housing 1 are arranged in a figure-eight pattern; this design facilitates the natural diversion and guidance of materials during the separation process. After magnetic and non-magnetic substances are separated on the drum, they flow along different paths to their respective outlets. Because the iron outlet 4 and the material outlet 3 are arranged in a figure-eight pattern, the crossing and confusion of materials at the outlet can be avoided more effectively, improving the clarity and accuracy of material separation.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
