Description
Technical Field
[0001] This utility model relates to a shredding device for waste lithium batteries. 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 shredding devices for waste lithium batteries use only blades for crushing, but some areas of the lithium battery often remain uncrushed during the fall, resulting in inconsistent output sizes. Therefore, conventional shredding devices are not ideal in terms of crushing effect. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a shredding device for waste lithium batteries with good crushing effect.
[0005] The purpose of this utility model is achieved as follows: The waste lithium battery shredding device includes a feeder. The discharge port at the bottom of the feeder is connected to a disc feeder, which is connected to the feed port at the top of a primary crusher. Both the primary and secondary crushers are equipped with multiple cutter discs arranged longitudinally side by side. Multiple grooves are formed on the outer edge of the cutter teeth. A motor is installed on each side of the primary and secondary crushers. The output shaft of the motor passes through the outer wall of the crusher and is connected to each cutter disc. In the parallel arrangement of cutter discs, the odd-numbered cutter discs are driven by the motor on the left, and the even-numbered cutter discs are driven by the motor on the right. The odd-numbered and even-numbered cutter discs rotate in opposite directions.
[0006] The bottom of the primary crusher and the top of the secondary crusher are connected by a detachable flange.
[0007] The primary and secondary crushers are also connected to external nitrogen pipelines. The bottom of the secondary crusher is equipped with a star-shaped discharge port.
[0008] An explosion-proof valve is installed in the discharge port of the feeder.
[0009] The feed inlet is funnel-shaped.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model relates to a shredding device for waste lithium batteries. By setting the cutter discs to rotate in different directions, the odd-numbered cutter discs are driven by a motor on the left, and the even-numbered cutter discs are driven by a motor on the right. The odd-numbered and even-numbered cutter discs rotate in opposite directions, which further improves the shredding effect. In addition, multiple grooves are formed on the blades on the outer edge of the cutter discs to assist the blades in shredding the waste lithium batteries and improve the shredding effect. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of the waste lithium battery shredding device of this utility model.
[0012] Figure 2 for Figure 1 Diagram showing the cutter head arrangement inside a medium crusher.
[0013] The components include: 1. Feeder; 2. Disc feeder; 3. Explosion-proof valve; 4. Primary crusher; 4.1 Feed inlet; 5. Secondary crusher; 6. Detachable flange; 7. Cutter disc; 8. Cutter teeth; 9. Groove; 10. Motor; 11. Nitrogen pipeline; 12. Star-shaped discharge port. Detailed Implementation
[0014] See Figure 1 and Figure 2 This utility model relates to a shredding device for waste lithium batteries, including a feeder 1, the discharge port at the bottom of the feeder 1 is connected to a disc feeder 2, and an explosion-proof valve 3 is installed in the discharge port.
[0015] The disc feeder 3 is connected to the feed inlet 4.1 at the top of the primary crusher 4. The feed inlet 4.1 is funnel-shaped, allowing the lithium battery to fall into the middle area of the primary crusher 4, thereby improving the crushing effect. The bottom of the primary crusher 4 is connected to the top of the secondary crusher 5 through a detachable flange 6, which allows for easy cleaning of the interior of both the primary crusher 4 and the secondary crusher 5 after disassembly.
[0016] Both the primary crusher 4 and the secondary crusher 5 are equipped with multiple cutter discs 7, which are arranged longitudinally side by side. Multiple grooves 9 are provided on the cutter teeth 8 on the outer edge of the cutter disc 7. The grooves 9 can assist the cutter teeth 8 in crushing waste lithium batteries and improve the crushing effect.
[0017] A motor 10 is installed on each of the two sides of the primary crusher 4 and the secondary crusher 5. The output shaft of the motor 10 passes through the outer wall of the crusher and is connected to each cutter disc 7. In the parallel arrangement of cutter discs 7, the odd-numbered cutter discs are driven by the motor on the left, and the even-numbered cutter discs are driven by the motor on the right. The odd-numbered and even-numbered cutter discs rotate in opposite directions, which further improves the crushing effect.
[0018] The primary crusher 4 and the secondary crusher 5 are also connected to an external nitrogen pipeline 11 for introducing nitrogen to protect the crushing environment. The bottom of the secondary crusher 5 is provided with a star-shaped discharge port 12, which is connected to the subsequent screw feeder.
