Description

Technical Field

[0001] This utility model relates to a feeding mechanism for crushing lithium batteries while they are charged. Background Technology

[0002] With the rapid development of the new energy industry, a wave of lithium battery retirements is quietly approaching. How to efficiently and environmentally recycle the electrode materials from used batteries has become an urgent problem for the industry to solve.

[0003] Current feeding mechanisms for crushing live lithium batteries have several problems: 1. The feeding structure during lithium battery crushing and recycling typically uses a dual gate valve feeding method. However, this feeding method allows different lithium batteries to enter the same cavity, which can easily lead to short circuits between the positive and negative electrodes and the concentrated generation of electrolyte, thus posing a safety hazard.

[0004] 2. Previous feeding structures could not be operated under power, which could not guarantee continuous and uniform crushing.

[0005] 3. Air and water can easily enter the cavity of the feeding mechanism, resulting in a higher impurity content in the recovered powder, requiring multiple screenings. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a feeding mechanism for lithium battery crushing that ensures continuous and uniform crushing, avoids battery short circuits, and prevents oxygen and water from entering.

[0007] The purpose of this utility model is achieved as follows: The feeding mechanism for crushing charged lithium batteries includes a chain conveyor and an oxygen-free feeder. The end of the chain conveyor is connected to the oxygen-free feeder, and the feed inlet of the oxygen-free feeder is connected to the end of the chain conveyor. The oxygen-free feeder includes a housing, which consists of a rotor, side housings, and an outer housing. There are two side housings, which are respectively installed and fixed to the two sides of the outer housing. The front end of the rotor passes through the side housings, and the end is connected to a drive motor. Multiple partitions are evenly installed on the outside of the rotor, dividing the outside of the rotor. The partitions, the side housings, and the outer housing form multiple cavities, each of which can hold a lithium battery. The bottom of the outer housing is connected to the discharge port. The outer housing also has multiple nitrogen charging inlets and air exhaust outlets, which are connected to external nitrogen pipes and exhaust pipes, respectively.

[0008] The front end of the chain conveyor is a feeding device, which is equipped with a weighing module.

[0009] The partitions, side boxes, and inner walls of the outer box are inlaid with rubber sheets.

[0010] An explosion-proof valve is installed in the pipeline where the feed inlet is located.

[0011] A temperature sensor and a flame detector are installed above the discharge port.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model relates to a feeding mechanism for lithium battery crushing under energized conditions. By incorporating an oxygen-free feeder, it operates while the battery is energized, ensuring continuous and uniform crushing and improving work efficiency. After the rotor rotates, individual lithium batteries can enter a single cavity, avoiding the problem of short-circuiting the positive and negative terminals of different batteries. As the internal rotor rotates, the lithium batteries inside each cavity are sequentially discharged from the discharge port and enter the next stage of the crushing system, ensuring that the material is evenly distributed to the next process and preventing the concentration of electrolyte. Simultaneously, the equipment has multiple cavities. After the lithium batteries are fed, the cavities remove any air introduced and inject nitrogen, preventing oxygen from entering and also preventing water from entering, ensuring that the powder in the subsequent screening contains fewer impurities.

Detailed Implementation

[0018] See Figures 1 to 4 This utility model relates to a feeding mechanism for crushing lithium batteries while they are charged, comprising a chain conveyor 1 and an oxygen-free feeder 2. The front end of the chain conveyor 1 is a feeding device 1.1, which includes a weighing module. Waste lithium batteries are placed in the feeding device 1.1 and then conveyed backwards via the chain conveyor 1. The end of the chain conveyor 1 is connected to the oxygen-free feeder 2, and the feed inlet 2.1 of the oxygen-free feeder 2 is connected to the end of the chain conveyor 1. The oxygen-free feeder 2 includes a housing 2.2.

[0019] The housing 2.2 consists of a rotor 2.3, side housings 2.4, and an outer housing 2.5. The outer housing 2.5 is annular. There are two side housings 2.4, which are fixed to the two sides of the outer housing 2.5 respectively. The front end of the rotor 2.3 passes through the side housing 2.4, and the end is connected to the drive motor 2.6. Multiple partitions 2.7 are evenly installed on the outside of the rotor 2.3, dividing the outside of the rotor 2.3. The partitions 2.7, side housings 2.4, and outer housing 2.5 form multiple cavities 2.8, each of which can hold a lithium battery. The inner walls of the partitions 2.7, side housings 2.4, and outer housing 2.5 are embedded with rubber plates for protection. The bottom of the outer housing 2.5 is connected to the discharge port 2.9, which is used to individually send the lithium batteries in each cavity 2.8 to the next process.

[0020] The outer casing 2.5 is also provided with multiple nitrogen inlets 2.10 and air outlets 2.11. The nitrogen inlets 2.10 and air outlets 2.11 are connected to external nitrogen pipes and exhaust pipes, respectively, for introducing nitrogen for protection and for discharging excess air. A temperature sensor 2.12 and a flame detector 2.13 are installed above the discharge port 2.9 for detecting temperature and flame. An explosion-proof valve 2.14 is installed in the pipe where the feed inlet 2.1 is located, which provides explosion protection.

[0021] The oxygen-free feeder is used to isolate oxygen during feeding. As the rotor rotates, individual lithium batteries can enter a single cavity, avoiding short circuits between the positive and negative terminals of different batteries. The equipment has multiple internal chambers; after the lithium batteries are fed in, the first chamber removes any air introduced, while the second chamber is filled with nitrogen to further isolate them from air. As the internal rotor rotates, the lithium batteries inside each chamber are sequentially discharged from the discharge port into the next stage of the crushing system, ensuring even material distribution to the next process and preventing safety hazards.

[0022] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
