Description

Technical Field

[0001] This utility model relates to the field of electrostatic separator technology, specifically an electrostatic separator for sorting lithium battery materials. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive and negative electrode materials and a non-aqueous electrolyte solution. Lithium-ion batteries contain metal powders such as lead and aluminum. In lithium-ion battery recycling, the dried mixed metal powders are typically sorted.

[0003] Electrostatic separators separate minerals with different electrical conductivity from each other when they pass through an electric field. Due to electrostatic induction or the capture of charged ions, these minerals acquire different charges and exhibit different characteristics within the electric field. Combined with gravity, they move along different trajectories. Then, with the aid of a receiving device, the minerals with different electrical conductivity are separated. Traditional electrostatic separators have poor dispersion mechanisms, which hinder subsequent separation, resulting in poor separation efficiency and incomplete separation. Utility Model Content

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.

[0020] Please see Figures 1 to 3 An embodiment of this utility model is provided: an electrostatic separator for sorting lithium battery materials, including a housing 10, on which a feeding assembly 20, a first sorting mechanism 30 and a second sorting mechanism 40 are installed sequentially from top to bottom. The first sorting mechanism 30 and the second sorting mechanism 40 form a double-layer separation structure to further improve the electrostatic separation effect.

[0021] The feeding assembly 20 includes a drive motor 21, a distributing trough 22, and a rotating shaft 23. The rotating shaft 23 is located inside the distributing trough 22 and is rotatably connected to it. The rotating shaft 23 passes through the front side of the distributing trough 22 and is linked to the drive motor 21. Multiple friction elements 24 are evenly arranged on the rotating shaft 23. The mixed material is poured into the distributing trough 22 through the feed inlet 25 at the top of the distributing trough 22. Simultaneously, the drive motor 21 drives the rotating shaft 23 to rotate, and the multiple friction elements 24 stir and rub against the mixed material. Among these, metal powder... Static electricity is generated, and the electrostatically charged metal powder is easier to separate by electrostatic separation. The mixed material flows from the distribution tank 22 to the first guide tank 26 connected to the bottom. The bottom of the first guide tank 26 is provided with a first vibration component 27, which includes an elastic structure 28 and a vibration motor 29 disposed on the side of the first guide tank 26. The first guide tank 26 vibrates through the cooperation of the elastic structure 28 and the vibration motor 29 to generate a projectile force, which disperses the mixed powder and improves the dispersion effect and the subsequent separation effect.

[0022] Furthermore, the first guide trough 26 divides the mixture in the dividing trough 22 into two parts, and guides them to the guide and sorting components 32 on the first sorting mechanism 30 respectively.

[0023] Both the first sorting mechanism 30 and the second sorting mechanism 40 include two electric sorting components 31, two material guiding and sorting components 32 and one unloading component 33. The two electric sorting components 31 and the two material guiding and sorting components 32 are arranged symmetrically, and the two material guiding and sorting components 32 are located in the middle of the chassis 10. The electric sorting components 31 are located diagonally above the material guiding and sorting components 32 and are close to the inner wall of the chassis 10.

[0024] The electro-sorting assembly 31 includes an electrode roller 311, a first brush 312, and a second drive motor 313. The electrode roller 311, the first brush 312, and the second drive motor 313 are linked by a belt. The first brush 312 is located near the inner wall of the housing 10. The electrode roller 311 is electrically connected to a high-voltage negative power supply. The second drive motor 313 drives the electrode roller 311 and the first brush 312 to rotate synchronously via the belt. The electrode roller 311 moves the charged material (metal powder) in the agitated and dispersed mixture in the direction of rotation of the electrode roller 311, while the first brush 313 rotates synchronously and comes into contact with and cleans the surface of the electrode roller 311 to prevent the metal powder from adhering to the surface of the electrode roller 311. The separated material passes through the metal discharge hopper 332 and the extended hopper 333 of the first sorting mechanism 30 in sequence before being discharged.

[0025] In this embodiment, the electrode roller 311 located on the left rotates counterclockwise and the electrode roller 311 located on the right rotates clockwise.

[0026] The material guiding and sorting assembly 32 includes a guide roller 321, a second brush 322, and a third drive motor 323. The guide roller 321, the second brush 322, and the third drive motor 323 are linked by a belt. The second brush 322 is located near the center of the housing 10. The third drive motor 323 drives the guide roller 321 and the second brush 322 to rotate via the belt. The guide roller 321 carries the uncharged material toward the mixing discharge hopper 331, while the second brush 333 rotates synchronously and cleans the surface of the guide roller 321 by contacting it, preventing the uncharged material from sticking to the surface of the guide roller 321.

[0027] The feeding assembly 33 includes a mixing discharge hopper 331 and a metal discharge hopper 332. The mixing discharge hopper 331 is located directly below the material guiding and sorting assembly 32, and the metal discharge hopper 332 is located directly below the electric sorting assembly 31. An extension hopper 333 is provided at the bottom of the metal discharge hopper 332 on the first sorting mechanism 10. The extension hopper 33 extends gradually outward from top to bottom.

[0028] The bottom of the mixing discharge hopper 331 on the first sorting mechanism 30 is provided with a second guide channel 334, and the bottom of the second guide channel 334 is provided with a second vibration component 335. The second vibration component 335 includes an elastic structure 336 and a vibration motor 337 disposed on the side of the second guide channel 334. The second guide channel 334 vibrates through the cooperation of the elastic structure 336 and the vibration motor 337 to generate a throwing force, which throws and disperses the mixed powder in the mixing discharge hopper 331 on the first sorting mechanism 30.

[0029] Furthermore, the second guide channel 334 divides the mixed material in the mixing discharge hopper 331 of the first sorting mechanism 30 into two parts, and guides them to the material guiding and sorting component 32 of the second sorting mechanism 40 respectively.

[0030] Furthermore, a second sorting mechanism 40 is used for secondary sorting, which further improves the sorting accuracy.

[0031] The frame 10 is also equipped with a vibrating loading assembly 11, which includes a strip hopper 12 and an elastic structure 3 13 at the bottom of the strip hopper 12. A vibrating motor 3 14 is installed on the elastic structure 3 13. The metal discharge hopper 332 of the second sorting mechanism 40 discharges metal powder into the strip hopper 12. The vibrating motor 3 14 drives the elastic structure 3 13 and the strip hopper 12 to vibrate, and the material can be evenly dispersed to the front and back sides. Packing bags can be hung on both sides of the strip hopper 12. The material is dispersed by vibration and falls into the packing bags to achieve the loading effect.

[0032] With the addition of the elastic structure 13, the vibrating motor 12, and the strip funnel 12, the material is fed into a smooth trough without the worm gear blades found in traditional technology, which facilitates subsequent cleaning work for operators.

[0033] In this embodiment, elastic structure 1 28, elastic structure 2 336 and elastic structure 3 13 are all support structures composed of multiple springs.

[0034] 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.
