Description

Technical Field

[0001] This utility model relates to the technical field of battery electrode separation devices, and in particular to an electrode separation device. Background Technology

[0002] In current battery recycling processes, the recycled electrode sheets (lithium iron phosphate positive electrode sheets) can have the binder between the aluminum foil (current collector) and the recycled electrode sheet material dissolved by a special solvent. Without the binder's adhesive effect, the dried recycled electrode sheets only require an external force to separate the aluminum foil and the recycled electrode sheet material. Existing separation and sorting methods are mostly manual.

[0003] Manual separation is labor-intensive and inefficient, failing to meet the needs of normal small and medium-scale pilot tests. In addition, manual separation also generates dust that can cause certain harm to human health. Utility Model Content

[0015] 1. In this utility model, a counterclockwise closed loop is formed by the forward blowing pipe and the reverse blowing pipe to form a shearing spiral airflow trajectory along the inner wall of the separation tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an electrode separation device, comprising a base 1, a fixing frame 2 fixedly connected to the upper surface of the base 1, a support rod 3 fixedly connected to the outer wall of the fixing frame 2, a tank 4 fixedly connected to the outer wall of the support rod 3, a fan 5 fixedly connected to the outer wall of the fixing frame 2, a forward blowing pipe 6 and a reverse blowing pipe 7 fixedly connected to the outer wall of the fan 5, the outer walls of the forward blowing pipe 6 and the reverse blowing pipe 7 being fixedly connected to the inside of the tank 4, a feeding port 8 and a discharging port 9 provided on the upper surface of the tank 4, a connecting cylinder 10 provided on the lower surface of the tank 4, and a dust-proof component provided on the lower surface of the connecting cylinder 10 to prevent dust contamination.

[0024] Specifically, the air duct outlet is designed at a 45-degree angle to provide a centripetal force when compressed air passes through the outlet, increasing the contact area with the recycled electrode sheet and better separating the aluminum foil and recycled electrode sheet material. The inner wall of the separation tank 4, the forward blowing pipe 6, the reverse blowing pipe 7, and the material tray 16 are all coated with polytetrafluoroethylene (PTFE) to avoid the introduction of magnetic foreign objects. The connecting cylinder 10 adopts a flexible connection method. By starting the fan 5, the air flows through the forward blowing pipe 6 and the reverse blowing pipe 7 in a spiral shape, which can effectively separate the aluminum foil and recycled electrode sheet material.

[0025] Reference Figure 1 and Figure 2 The dustproof assembly includes a dust cover 11, the upper surface of which is disposed on the lower surface of the connecting cylinder 10, and dust collection pipes 12 are fixedly connected to the upper surfaces of both the dust cover 11 and the tank 4.

[0026] Specifically, a transparent dust cover 11 is designed above the material tray 16, which allows for observation of the separation and sorting of the recycled electrode sheets at any time and effectively prevents dust from entering the air and causing environmental pollution. The dust collection pipe 12 can not only effectively discharge excess gas in the separation device and maintain the air pressure balance in the separation tank 4, but also achieve the purpose of dust collection and avoid environmental pollution.

[0027] Reference Figure 1 and Figure 3 A housing 13 is fixedly connected to the upper surface of the base 1. A bracket 14 is fixedly connected to the inner wall of the housing 13. A vibration isolation spring 15 is fixedly connected to the upper surface of the bracket 14. A material tray 16 is fixedly connected to the upper surface of the vibration isolation spring 15. A buffer ring 17 is provided on the outer wall of the material tray 16. The outer wall of the buffer ring 17 is provided on the inner wall of the housing 13. A vibrator 18 is fixedly connected to the lower surface of the material tray 16. A vibration motor 19 is fixedly connected to the lower surface of the vibrator 18. A buckle 20 is fixedly connected to the outer wall of the housing 13. The upper outer wall of the buckle 20 is provided on the outer wall of the dust cover 11.

[0028] Specifically, the vibrating motor 19 drives the vibrating body 18 to vibrate, and the vibrating body 18 causes the raw material to move up and down through the material tray 16. Vibration will cause increased friction and wear between various parts of the equipment. The vibration isolation spring 15 and the buffer ring 17 reduce wear. By reducing vibration, the noise generated during equipment operation can also be reduced. The variable frequency vibrating motor 19 can use different vibration frequencies to improve work efficiency. The dust cover 11 and the outer shell 13 are connected by the buckle 20, which makes it easier to disassemble the dust cover 11 and separate the aluminum foil floating on top.

[0029] Working principle: When using this device, raw materials are fed into the feeding port 8. The vibration motor 19 is started to drive the vibrator 18 to vibrate. The vibrator 18 drives the material tray 16 to vibrate. Under the action of the vibrator 18, the aluminum foil and recycled electrode sheet materials have different densities and masses, resulting in different gravitational forces. The material with lower mass and density will move upward, while the material with higher mass and density will move downward. At the same time, the fans 5 on both sides are turned on. The fans 5 blow air into the tank 4 through the forward blowing pipe 6 and the reverse blowing pipe 7. The forward blowing pipe 6 and the reverse blowing pipe 7 form a counterclockwise closed loop, forming a shearing spiral airflow trajectory along the inner wall of the separation tank 4, effectively separating the aluminum foil and recycled electrode sheet materials. Dust will be generated during the vibration and blowing process. Dust pollution can be effectively avoided by the dust cover 11 and the dust collection pipe 12. The dust cover 11 and the outer shell 13 are connected by the buckle 20, which makes it easier to remove the dust cover 11. This device can not only automatically separate aluminum foil and recycled electrode sheet materials to save manpower, but also improve work efficiency by using different vibration frequencies.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
