Description

Technical Field

[0001] This utility model belongs to the field of waste battery recycling technology, specifically relating to an eddy current metal separation device for separating waste battery pyrolysis products. Background Technology

[0002] Used batteries are discarded batteries that have been used. After being discarded, the battery casing slowly corrodes, and the heavy metals inside gradually seep into water and soil, causing pollution. To avoid this pollution, used batteries are recycled. Batteries contain various precious metals with recycling value, such as cobalt, manganese, and lithium. The positive electrode of discarded lithium batteries contains a large amount of precious metals, including 5-20% cobalt, 5-12% nickel, 7-10% manganese, 2-5% lithium, and 7% plastic. Most of the metals contained are rare metals. Therefore, recycling used lithium-ion batteries has significant economic value and is also beneficial to protecting the ecological environment.

[0003] Currently, relevant separation equipment exists on the market. For example, a waste battery crushing, separation, and recycling mechanism proposed in announcement number CN219483737U includes a separation and recycling box, a receiving and conveying box fixedly installed on the inner wall of the separation and recycling box, a separation mechanism at the bottom of the separation and recycling box, and a conveying mechanism inside the receiving and conveying box. Its main separation rollers scrape off the surface of the shell for separation.

[0004] The existing separation devices mentioned above use scraping for separation. However, after the battery is cracked and broken, there are many impurities inside the battery. Scraping with rollers can only remove fine dust on the surface and cannot effectively separate the cracked graphite and other electrolyte substances inside, resulting in poor separation effect and certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide an eddy current metal separation device for separating waste battery pyrolysis products, in order to solve the problem mentioned in the background art that existing waste battery pyrolysis product separation devices can only separate fine impurities on the surface of the shell and cannot effectively separate impurities such as graphite inside the battery. This device, by adopting an existing eddy current metal separation device, effectively separates the metal. It uses a vibration feeding method, which can make the pyrolysis products feed evenly and can shake off the dust on the surface of the metal materials to a certain extent. It can effectively separate the metal in a targeted manner. Compared with traditional separation devices, this device has significant advantages.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste battery pyrolysis product separation device using eddy current metal separation, comprising a sorting machine body, a collecting device at one end of the sorting machine body, a feeding trough at the other end of the sorting machine body, fixed columns fixedly connected to the four corners of the lower end of the feeding trough, a supporting leg slidably sleeved at the lower end of the fixed column, a fixed base plate fixedly connected to the lower end of the supporting leg, a spring sleeved on the outer surface of the fixed column, one end of the spring fixedly connected to the feeding trough, and the other end of the spring fixedly connected to the supporting leg, a collecting trough on one side of the inside of the feeding trough, a feeding channel on the other side of the inside of the feeding trough, the feeding channel having a certain inclination, and a vibrator fixedly connected to one side of the lower end of the feeding trough.

[0007] Preferably, a fixed bracket is fixedly connected to one side of the upper end of the feeding trough, a limiting groove is fixedly formed on the inner wall of the fixed bracket, a sliding block is slidably connected to the inner wall of the limiting groove, and a baffle plate is fixedly connected to the lower end of the sliding block.

[0008] Preferably, a threaded sleeve is fixedly connected to the upper end of the sliding block, and a threaded rod is threadedly sleeved on the upper end of the threaded sleeve. The threaded rod is rotatably positioned at the center of the fixed bracket, and a rotating handle is fixedly connected to one end of the threaded rod.

[0009] Preferably, a drive device is fixedly connected to one side of the sorting machine body, a cleaning brush roller is rotatably connected to the lower end of the sorting machine body, the drive device is fixedly connected to the cleaning brush roller via a shaft, and a dust collection box is fixedly connected to the lower end of the sorting machine body, the dust collection box being located below the cleaning brush roller.

[0010] Preferably, the driving device includes a motor housing, a drive motor, and a power supply assembly. The motor housing has heat dissipation windows on both sides. The drive motor is fixedly connected to one side of the motor housing, and the power supply assembly is fixedly connected to the other side of the motor housing. The drive motor is electrically connected to the power supply assembly through wires.

[0011] Preferably, the collecting device has a partition fixedly connected inside, one side of the partition is a sludge box, the other side of the partition is a recycling box, and an arc baffle is fixedly connected to the upper end of the partition.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model improves the sorting efficiency by using existing sorting machines to sort the pyrolysis products of waste batteries. During feeding, the pyrolysis products of waste batteries are placed in a trough with a flexible connection. When a vibrator connected to a fixed connection is powered on, it causes the material and trough to vibrate up and down, thus ensuring even feeding and dislodging of some attached materials, resulting in better separation. An adjustable-height baffle is used during feeding to intercept some accumulated products. Through continuous vibration, the accumulated products disperse and pass through the baffle, preventing accumulation from affecting the separation effect.

[0014] 2. This utility model has a cleaning device fixed at the lower end of the sorting machine. After the separated materials are separated, the power of the drive device can be turned on to drive the cleaning brush roller to rotate and clean the surface of the conveyor belt. This can prevent some small products from adhering to the surface of the conveyor belt. Long-term accumulation will affect the magnetic field and thus affect the sorting effect.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an eddy current metal separation device for separating waste battery pyrolysis products, including a sorting machine body 1, a collecting device 2 at one end of the sorting machine body 1, a feeding trough 3 at the other end of the sorting machine body 1, fixed posts 4 fixedly connected to the four corners of the lower end of the feeding trough 3, a support leg 5 slidably sleeved at the lower end of the fixed post 4, a fixed base plate 6 fixedly connected to the lower end of the support leg 5, a spring 7 sleeved on the outer surface of the fixed post 4, one end of the spring 7 fixedly connected to the feeding trough 3, and the other end of the spring 7 fixedly connected to the support leg 5, a collecting trough 9 is provided on one side of the inside of the feeding trough 3, a feeding channel 10 is provided on the other side of the inside of the feeding trough 3, the feeding channel 10 has a certain inclination, and a vibrator 8 is fixedly connected to one side of the lower end of the feeding trough 3.

[0022] In this implementation scheme, an existing sorting machine body 1, such as the BZY450 sorting machine, is used. The battery degradation products are placed inside the collection trough 9. When the vibrator 8 at the bottom of the discharge trough 3 is powered on, it can rotate. The fixed base plate 6 allows for threaded fixation of the support legs 5 after the entire assembly is placed, resulting in better stability. Since the fixing column 4 is slidably positioned inside the support legs 5 and limited by the spring 7, the discharge trough 3 and the support legs 5 are in an elastic connection. When the vibrator 8 is powered on, it causes the discharge trough 3 to vibrate up and down. The product placed in the collection trough 9 can be vibrated and fed along the feeding channel 10. During the vibration process, the material can be evenly distributed, and the dust and other adhering particles on the surface can be removed to a certain extent. When the product is fed onto the surface of the sorting machine body 1, it can be transported. When it is transported to the end, the metal and non-metal materials can be separated under the action of the magnetic field. This design method uses the magnetic field generated by eddy current to exert a force on the metal material, which can quickly separate the metal in the waste battery. It is highly efficient, and the vibration feeding method can evenly distribute the material and remove the surface adhering substances to a certain extent, which has a good separation effect.

[0023] Specifically, a fixed bracket 11 is fixedly connected to one side of the upper end of the feeding trough 3. A limiting groove 12 is fixedly opened on the inner wall of the fixed bracket 11. A sliding block 13 is slidably connected to the inner wall of the limiting groove 12. A baffle plate 18 is fixedly connected to the lower end of the sliding block 13.

[0024] In this embodiment, the baffle plate 18 can limit the height of the product during feeding, preventing the product from piling up and being difficult to disperse through vibration. It can intercept and restrict the products that are piled up, and disperse them through continuous vibration before they can pass through. This design method uses a height-limiting baffle to intercept the pyrolysis products that are piled up. After interception, they can be slowly dispersed through continuous vibration until they reach the required height before they can pass through. This can effectively prevent the product from piling up and affecting the separation effect.

[0025] Specifically, a threaded sleeve 14 is fixedly connected to the upper end of the sliding block 13, and a threaded rod 15 is threadedly connected to the upper end of the threaded sleeve 14. The threaded rod 15 is rotatably set at the center of the fixed bracket 11, and a rotating handle 17 is fixedly connected to one end of the threaded rod 15.

[0026] In this embodiment, the rotating handle 17 can be used to rotate the threaded rod 15. After the threaded rod 15 rotates, the threaded sleeve 14 will rotate. Since the threaded sleeve 14 is fixed to the upper end of the sliding block 13 and the sliding block 13 is limited to sliding inside the limiting groove 12, the sliding block 13 can only slide. At this time, after the threaded rod 15 rotates, it can drive the sliding block 13 to rise and fall, thereby raising and lowering the height of the baffle plate 18. The interception height can be adjusted according to the actual situation, making operation more convenient.

[0027] Specifically, a drive unit 19 is fixedly connected to one side of the sorting machine body 1, and a cleaning brush roller 20 is rotatably connected to the lower end of the sorting machine body 1. The drive unit 19 is fixedly connected to the cleaning brush roller 20 via a shaft, and a dust collection box 21 is fixedly connected to the lower end of the sorting machine body 1. The dust collection box 21 is located below the cleaning brush roller 20.

[0028] In this embodiment, the driving device 19 can drive the cleaning brush roller 20 to rotate after the drive rotates, thereby cleaning the surface of the conveyor belt of the sorting machine body 1 to a certain extent. This prevents some impurities and dust in the pyrolysis products from adhering to the surface of the conveyor belt and accumulating over a long period of time, which would affect the magnetic field. This design can clean the surface of the conveyor belt after separation, preventing dust from accumulating on the surface of the conveyor belt for a long time, which would affect the magnetic field and thus affect the separation effect. It has a certain cleaning effect and is more convenient without the need for manual cleaning.

[0029] Specifically, the drive unit 19 includes a motor housing 26, a drive motor 27, and a power supply assembly 28. The motor housing 26 has heat dissipation windows on both sides. The drive motor 27 is fixedly connected to one side of the interior of the motor housing 26, and the power supply assembly 28 is fixedly connected to the other side of the interior of the motor housing 26. The drive motor 27 is electrically connected to the power supply assembly 28 through wires.

[0030] In this embodiment, the power supply component 28 can provide power to the drive motor 27, so that the drive motor 27 can be driven to rotate.

[0031] Specifically, a partition 24 is fixedly connected inside the collection device 2. One side of the partition 24 is a sludge box 22, and the other side of the partition 24 is a recycling box 23. An arc baffle 25 is fixedly connected to the upper end of the partition 24.

[0032] In this embodiment, the inside of the collection device 2 is divided into two spaces by a partition 24 fixed inside the collection device 2. The arc baffle 25 provides some shielding. Under the action of the magnetic field at the end of the conveyor belt, the metal material falls from the upper end of the arc baffle 25 into the recycling box 23, while the non-metallic material falls from the lower side of the arc baffle 25 into the impurity box 22 for separation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
