Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a impurity removing device for processing the negative electrode material of a lithium battery. Background Art

[0002] Basically, the negative electrode materials of lithium-ion batteries are carbon materials, such as artificial graphite, natural graphite, etc. In the process of graphite production, it is inevitable that due to human operation errors or machine reasons, etc., more impurities are mixed in the graphite. Among them, there are more cases of iron filings mixed in, resulting in low purity of the graphite powder and affecting the final product quality. Therefore, it is necessary to separate the iron filings from it. At present, the commonly used method for separating iron filings impurities is the magnetic separation method. Utilizing the property that iron filings are easily attracted by magnets, an electromagnetic rod is used for adsorption.

[0003] The existing adsorption method is usually to sprinkle the graphite on the electromagnetic rod little by little manually. This method is not only time-consuming and laborious, but also the gap between the electromagnetic rods easily causes too many iron filings not to be adsorbed. Summary of the Utility Model

[0025] 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 of 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.

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0027] Referring to Figures 1 - 4 , the present utility model provides a impurity removal device for processing lithium battery anode materials, including:

[0028] A housing 1 with open top and bottom openings;

[0029] A first support ring 2, which is circumferentially fixedly connected to the inner side wall of the housing 1. A vibration ring 3 is arranged below the first support ring 2. An elastic component is arranged between the vibration ring 3 and the first support ring 2. The inner ring of the vibration ring 3 is fixedly connected with a screen 4;

[0030] A second support ring 5, which is circumferentially fixedly connected to the inner side wall of the housing 1. The top surface of the second support ring 5 is rotatably connected with a rotating ring 6. An extrusion component is arranged between the rotating ring 6 and the vibration ring 3. A plurality of electromagnetic rods 7 are fixedly connected to the inner side wall of the rotating ring 6, and the electromagnetic rods 7 are located below the screen 4;

[0031] The motor 8 is fixedly installed on the outer side wall of the housing 1, and the output shaft of the motor 8 is drivingly connected to the rotating ring 6 through a transmission assembly;

[0032] The first support ring 2, the vibration ring 3, the second support ring 5 and the rotating ring 6 are coaxially arranged.

[0033] By filling graphite on the screen 4, starting the motor 8 drives the rotating ring 6 to rotate through the transmission assembly. When the rotating ring 6 rotates, multiple electromagnetic rods 7 rotate synchronously, and through the cooperation of the extrusion assembly and the elastic assembly, the vibration ring 3 is continuously vibrated, so that the graphite on the screen 4 gradually and automatically spills. At the same time, since the electromagnetic rods 7 rotate synchronously with the rotating ring 6, during the rotation of the multiple electromagnetic rods 7, the existence of the flow gap can be relatively reduced, the contact efficiency between the electromagnetic rods 7 and the spilled graphite can be improved, thereby improving the adsorption effect on iron filings and the purity of the filtered graphite.

[0034] Further, the rotating ring 6 is slidably connected to the second support ring 5 through a card slot or a slide rail.

[0035] In a further optimized solution, the elastic assembly includes a plurality of first connecting rods 9. The first connecting rods 9 are fixedly connected to the vibration ring 3. A plurality of through holes for the first connecting rods 9 to slidably penetrate are formed on the first support ring 2. One end of the first connecting rod 9 far from the vibration ring 3 penetrates the through hole and is fixedly connected with a limiting plate 10. The size of the limiting plate 10 is larger than that of the through hole. A spring 11 is sleeved on the first connecting rod 9, and the spring 11 is fixedly connected between the first support ring 2 and the vibration ring 3. The extrusion assembly includes a plurality of second connecting rods 12 and a plurality of first spherical heads 13. The second connecting rods 12 are circumferentially and fixedly connected to the top surface of the rotating ring 6. One end of the second connecting rod 12 far from the rotating ring 6 is fixedly connected with a second spherical head 14. A plurality of first spherical heads 13 are circumferentially and fixedly connected to the bottom surface of the vibration ring 3, and the plurality of first spherical heads 13 are used to abut against the plurality of second spherical heads 14.

[0036] Through the support of the limiting plate 10 and the elastic tension of the spring 11, when the rotating ring 6 rotates, the second spherical head 14 is driven to rotate synchronously through the second connecting rod 12, so that the first spherical head 13 and the second spherical head 14 abut against each other, and the first spherical head 13 drives the vibration ring 3 to move upward, and in cooperation with the tension of the spring 11, the vibration ring 3 is vibrated.

[0037] In a further optimized solution, the transmission assembly includes a meshing gear 15 and a toothed ring 16. The toothed ring 16 is circumferentially and fixedly connected to the outer side wall of the rotating ring 6. The gear 15 is fixedly connected to the output shaft of the motor 8. A groove for accommodating the toothed ring 16 is circumferentially formed on the inner side wall of the housing 1, and the groove communicates with a through groove for accommodating a part of the gear 15 and communicating with the outside.

[0038] The motor 8 drives the gear 15 to rotate, so that the gear 15 drives the gear ring 16 and the rotating ring 6 to rotate synchronously.

[0039] The thickness of the groove is smaller than the thickness of the rotating ring 6, so that the rotating ring 6 can block the position of the groove, and sealing measures are taken to prevent the graphite from getting stuck in the groove gap.

[0040] In a further optimized solution, a coaxial spacer ring 17 is fixedly connected between the vibration ring 3 and the first support ring 2. The spacer ring 17 is used to isolate the graphite to prevent the graphite from contacting structural components such as the spring 11, and the spacer ring 17 is made of a flexible and deformable material.

[0041] In a further optimized solution, the screen 4 is conical, which can hold the graphite and make the graphite slide down effectively and concentratedly.

[0042] In a further optimized solution, the bottom of the housing 1 is conical, which is convenient for the filtered graphite to be discharged concentratedly.

[0043] In a further optimized solution, a bracket 18 is fixedly connected to the bottom of the housing 1.
