Technical Field
[0001] This utility model relates to the field of lithium battery recycling technology, specifically to a metal extraction device for lithium battery recycling. Background Technology
[0002] Lithium battery recycling refers to the process of processing used lithium batteries to achieve resource reuse and environmental protection. When recycling lithium battery casings, crushing equipment is needed to crush the casings to facilitate the extraction and collection of metals.
[0003] A search revealed that the patent, CN218945902U, entitled "Utility Model of Metal Extraction Equipment for Lithium Battery Recycling," includes a base. Research and analysis revealed that while it has advantages such as being able to pulverize waste lithium batteries multiple times during use and making the pulverization more thorough, it also has certain disadvantages.
[0004] For example, if the device lacks a guiding function, it cannot effectively guide the lithium battery casings into the crushing chamber. This can lead to issues such as misalignment of the feeding position, stacking and congestion, or excessive concentration in a single area when the lithium battery casings enter the crushing chamber. Consequently, the casings cannot make uniform contact with the crushing components, causing a sudden increase in local load within the crushing chamber, exacerbating uneven wear of the blades and hammers, shortening the service life of core components, and causing equipment vibration and abnormal noise due to force imbalance, increasing the frequency of downtime. To solve the above technical problems, we have designed a metal extraction device for lithium battery recycling. Utility Model Content

[0021] Please see Figures 1-4A metal extraction device for lithium battery recycling includes a housing 1. Crushing rollers 2 are movably connected to both sides of the front side of the inner cavity of the housing 1 via bearings. The crushing rollers 2 can squeeze and shear the input lithium battery casing, providing uniformly sized crushed material for subsequent metal extraction. The rear end of the crushing rollers 2 extends to the rear side of the housing 1 and is bolted to a gear 3. The gear 3 synchronously transmits the rotational power of a reduction motor 5 to the two crushing rollers 2, ensuring that the two crushing rollers 2 always maintain a relative and synchronous rotation, guaranteeing a stable crushing process. A frame 4 is riveted to the right side of the rear side of the housing 1. A reduction motor 5 is bolted to the rear side of the frame 4. The reduction motor 5 can... The high-speed motor output is converted into the low-speed, high-torque power required by the crushing roller 2, adapting to the crushing requirements of hard materials such as lithium battery casings. The model of the geared motor 5 is RV30-750W-1 / 50 worm gear reducer motor. The output end of the geared motor 5 passes through the frame 4 and is connected to the gear 3 on the right side by bolts. Support plates 6 are riveted to both sides of the top rear side of the housing 1. The right side of the support plate 6 is movably connected to the right side of the first lead screw 7. Adjusting plates 8 are threaded on both sides of the surface of the first lead screw 7. The front side of the adjusting plate 8 is riveted with a first limiting plate 9. By setting the first limiting plate 9 and adjusting the distance between the two first limiting plates 9, it can adapt to lithium battery casings of different widths and sizes, preventing materials from being crushed in the feed. During the process, the material is offset along the left and right direction of the box body 1 to ensure that it falls accurately into the meshing area of the two crushing rollers 2. The top of the front side and the top of the rear side of the box body 1 are both threadedly connected to the second lead screw 10. The opposite ends of the second lead screw 10 are movably connected to the second limiting plate 11 through the bearing. By setting the second limiting plate 11, the offset of the lithium battery shell along the front and back direction of the box body 1 during feeding can be limited, ensuring that the material is evenly distributed along the entire length of the crushing roller 2, so that the crushing teeth on the surface of the crushing roller 2 are evenly stressed, and avoiding the aggravation of wear caused by sudden increase in local load. The two sides of the rear side of the box body 1 are bolted to the drive motor 12. By setting the drive motor 12, the rotating drum 13 and the ultrasonic sensor 14 can be rotated. The motor 12 is powered to enable the detection position switching function. It can drive the rotating drum 13 to rotate 180° precisely, so that the ultrasonic sensor 14 can rotate from the initial position to the detection position of the crushing teeth on the surface of the crushing roller 2. After the detection is completed, it can rotate in the opposite direction to reset. The operation is flexible. The output end of the drive motor 12 passes through the inner cavity of the housing 1 and is fixedly connected to the rotating drum 13. The ultrasonic sensor 14 is bolted to the opposite side of the rotating drum 13. By setting the ultrasonic sensor 14, the crushing teeth on the surface of the crushing roller 2 can be detected in real time using the ultrasonic reflection principle, and the faults such as breakage, damage, and excessive wear of the crushing teeth can be accurately identified. The ultrasonic sensor 14 is an HC-SR04PLUS industrial-grade ultrasonic ranging sensor.
[0022] Please see Figure 1 and Figure 4The threads on both sides of the surface of the first lead screw 7 are rotated in opposite directions. The right end of the first lead screw 7 is riveted with a first handwheel 15. By setting the first handwheel 15, the first lead screw 7 can be easily rotated without the need for additional tools, thus reducing the difficulty of operation. The opposite ends of the second lead screw 10 are riveted with second handwheels 16.
[0023] Please see Figure 1 Guide rods 17 are riveted to the opposite side of the second limiting plate 11. By setting the guide rods 17, the second limiting plate 11 can be guided so that it can only move back and forth. The opposite ends of the guide rods 17 extend to the outside of the box 1.
[0024] Please see Figure 2 The rear side of the housing 1 is provided with a first guide hole 18. By setting the first guide hole 18, it can be ensured that the first adjusting plate 8 moves only in the left and right direction. The front side of the adjusting plate 8 passes through the first guide hole 18.
[0025] Please see Figure 1 The front side of the housing 1 is provided with a second guide hole 19, and the front side of the first limiting plate 9 is riveted with a guide block 20. By setting the second guide hole 19 and the guide block 20, the first limiting plate 9 can be guided, making it more stable during left and right movement. The front side of the guide block 20 extends into the inner cavity of the second guide hole 19.
[0026] Please see Figure 3 Both sides of the inner cavity of the box body 1 are riveted with a first guide plate 21, which is located on the top of the crushing roller 2. A second guide plate 22 is riveted to the bottom of the inner cavity of the box body 1. By setting the second guide plate 22, the crushed lithium battery debris can be guided to quickly converge to the discharge holes 23 on both sides of the box body 1, avoiding the accumulation of debris at the bottom of the box body 1 and ensuring smooth discharge.
[0027] Please see Figure 1 and Figure 3 The bottom of both sides of the box 1 is provided with discharge holes 23. Both sides of the box 1 are connected to the inspection plate 24 by hinges. The inspection plate 24 makes it convenient for users to inspect the ultrasonic sensor 14. Both sides of the box 1 are connected to the audible and visual alarm 25 by bolts. The audible and visual alarm 25 can quickly remind the staff to stop the machine for maintenance in time, so as to avoid the failure from causing a decrease in crushing efficiency, equipment damage or safety hazards.
[0028] In use, the positions of the first limiting plate 9 and the second limiting plate 11 are adjusted according to the size of the lithium battery casing. Rotating the first handwheel 15 rotates the first lead screw 7, which, through a threaded connection with the adjusting plate 8, causes the adjusting plate 8 to move. The adjusting plate 8 then moves the first limiting plate 9, resulting in relative movement between the two limiting plates. Next, rotating the second handwheel 16 rotates the second lead screw 10, causing relative movement between the two limiting plates 11. Under the action of the first limiting plates 9 and the second limiting plates 11, the lithium battery casing is guided to make uniform contact with the crushing roller 2, improving the subsequent crushing effect. Then, an external controller controls the operation of the reduction motor 5. The output of the geared motor 5 drives the right gear 3 to rotate, and the rotation of the right gear 3 simultaneously drives the left gear 3 to rotate. The two gears 3 drive the crushing roller 2 to rotate. The relative rotation between the two crushing rollers 2 crushes the lithium battery casing. The crushed debris is discharged to the outside of the box 1 through the second guide plate 22 and the discharge hole 23. When the crushing roller 2 is running, the external controller controls the drive motor 12 to run. The output of the drive motor 12 drives the rotating drum 13 to rotate 180 degrees. The ultrasonic sensor 14 detects the crushing teeth on the surface of the crushing roller 2. When the crushing teeth are detected to be broken or damaged, the external controller controls the sound and light alarm 25 to alarm the staff, so that timely maintenance can be carried out to avoid affecting the crushing effect.
[0029] In summary, this metal extraction device for lithium battery recycling solves the problem that existing metal extraction devices for lithium battery recycling cannot effectively guide the input lithium battery casings during use, which leads to problems such as feed position deviation, stacking congestion, or excessive concentration in a single area when the lithium battery casings enter the crushing chamber. This is achieved through the cooperation of the support plate 6, the first lead screw 7, the adjusting plate 8, the first limiting plate 9, the second lead screw 10, the second limiting plate 11, the drive motor 12, the rotating drum 13, the ultrasonic sensor 14, and the audible and visual alarm 25.
