Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, specifically to a lithium battery recycling volatilization furnace. Background Technology

[0002] The core process of lithium battery recycling can be summarized into three major stages: pretreatment, extraction, and purification. The mainstream technologies are divided into two types: wet and pyrometallurgical. The ultimate goal is to recover precious metals such as lithium, cobalt, and nickel. The core of pyrometallurgical methods is high-temperature removal of organic matter and smelting separation. A pyrometallurgical furnace is a common term that usually refers to thermal equipment in lithium battery recycling that uses temperature and pressure differences to achieve material separation, such as pyrolysis furnaces, rotary kilns, and roasting furnaces. In pyrometallurgical processes, it is used in specific scenarios, such as removing volatile impurities from batteries and recovering the volatilization of specific metals. Among them, the rotary kiln continuously heats the crushed material after lithium battery recycling in a protective atmosphere to achieve the effects of decomposing organic matter and efficiently recovering metals.

[0003] A rotary kiln for quicklime production, application number 202422569070.0, includes a kiln body, a front support, and a rear support. The kiln body is installed at an inclination. A feed inlet is fixedly connected to the higher end of the kiln body, and a discharge outlet is fixedly connected to the other end. A gear ring and a roller ring are fixedly connected to the outer side of the kiln body. Two motors are fixedly connected to the front support, and gears are fixedly connected to the output shafts of the motors. The gears mesh with the gear ring. Two rollers are rotatably connected to the rear support, and the rollers are embedded in the roller ring and rotatably connected to it. A vibration device is fixedly connected to the outer side of the kiln body near the feed inlet, and several anti-sticking cones are fixedly connected to the inner side of the kiln body near the feed inlet. This utility model utilizes the rotation of the rotary kiln to drive the vibration balls to strike the feed end of the kiln body, which can prevent materials from adhering to the kiln lining. By using the anti-sticking cones fixedly connected to the feed end of the inner wall of the kiln body, the adhered materials can be more easily dislodged when the vibration balls strike the kiln body when they move to the top.

[0004] The magnetic control during its processing is difficult. The magnetic force drives the displacement of the vibration ball to facilitate subsequent vibration of the kiln body. However, the movement trajectory and force of the vibration ball need to be precisely matched with the magnitude of the magnetic force. Moreover, the components are easily damaged and inconvenient to maintain. The vibration function of this type of rotary kiln relies on the direct impact between the components. The connecting parts between the vibration ball and the vibration device are prone to wear and deformation under long-term impact, and are not easy to replace. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lithium battery recycling volatilization furnace to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery recycling volatilization furnace, comprising a rotary kiln body and a kiln frame, wherein a support is connected to one side of the top of the rotary kiln body, and a magnetic suction plate is installed inside the support; a fixing frame is fixed to the outside of the kiln frame, and a guide cylinder is connected to the top of the fixing frame; a cover plate is connected to the top of the guide cylinder, and a buffer block is connected to the middle of the bottom of the cover plate; a liner plate penetrates one side of the guide cylinder, and a hammer ball is placed inside the guide cylinder.

[0007] By adopting the above technical solution, the bracket provides stable support for the magnetic suction plate, ensuring that the magnetic suction plate can accurately act on the trajectory of the hammer ball; when the fixed frame rotates synchronously with the kiln body, it can drive the guide cylinder, cover plate, buffer block, liner, and hammer ball to revolve together, laying the foundation for the hammer ball to obtain falling kinetic energy; at the same time, the buffer block and liner can respectively play the role of impact buffering and impact bearing for the hammer ball, avoiding direct damage to components during the vibration process, and ultimately reducing the adhesion of materials to the inner wall of the kiln through the vibration action of the hammer ball.

[0008] Furthermore, the hammer ball is rotatably connected to the guide cylinder, and the hammer ball abuts against the liner plate.

[0009] By adopting the above technical solution, the rolling connection between the hammer ball and the guide cylinder can ensure that the hammer ball can fall smoothly along the guide cylinder under the action of gravity; while the abutting design between the hammer ball and the liner plate can directly transmit the impact force of the hammer ball when it falls to the liner plate, and then transmit it to the fixed frame and the kiln body through the liner plate, ensuring that the vibration effectively acts on the inner wall of the kiln body and improves the material adhesion and cleaning effect.

[0010] Furthermore, the hammer ball abuts against the buffer block, and the buffer block is made of rubber material.

[0011] By adopting the above technical solution, the contact between the hammer ball and the buffer block can prevent the hammer ball from directly impacting the cover plate. The rubber material has good elastic deformation ability and can absorb part of the axial impact force when the hammer ball falls, reducing the rigid collision damage between the hammer ball and the cover plate and extending the service life of both. At the same time, the buffered impact force can be transmitted to the liner more smoothly, avoiding excessive local impact force that could cause component deformation and ensuring the long-term stable operation of the shock structure.

[0012] Furthermore, the magnetic suction plate is arc-shaped.

[0013] By adopting the above technical solution, the arc-shaped structure can be adapted to the arc-shaped outer surface of the kiln body, so that the magnetic absorbing plate can fit the revolution trajectory of the hammer ball and expand the magnetic attraction range. When the hammer ball revolves with the guide cylinder, it can remain in the effective magnetic attraction area of ​​the magnetic absorbing plate, ensuring that the magnetic absorbing plate can stably attract the hammer ball and carry it to a high place. There is no need to make precise adjustments to the position or magnetic force of the magnetic absorbing plate, which greatly reduces the difficulty of magnetic force control.

[0014] Furthermore, multiple guide cylinders, cover plates, buffer blocks, liners, and hammer balls are provided, and these multiple guide cylinders, cover plates, buffer blocks, liners, and hammer balls are distributed in a ring array.

[0015] By adopting the above technical solution, the synchronous operation of multiple components can increase the vibration frequency and coverage, further reduce the adhesion of materials to the inner wall of the kiln, ensure that the lithium battery crushed material is heated evenly in the kiln, and improve the decomposition efficiency of organic matter and the metal recovery effect.

[0016] Furthermore, the kiln body extends through both sides of the rotary kiln body, one end of the kiln body is connected to a smoke chamber, and the top of the smoke chamber is connected to a smoke exhaust port. One side of the smoke chamber is connected to a feed inlet, and the other end of the kiln body is connected to a kiln head. The kiln head and the smoke chamber are connected to the kiln body with a seal, and the bottom of the kiln head is connected to a discharge port.

[0017] By adopting the above technical solutions, the feed inlet facilitates the stable entry of crushed lithium battery material into the kiln body, and the kiln body, which runs through the rotary kiln body, ensures its stability during rotation; the smoke chamber can collect the flue gas generated during the heating process of the kiln body and discharge it through the exhaust port, avoiding the retention of flue gas and affecting material processing; the sealing structure at the kiln head and the smoke chamber can ensure that the kiln environment is sealed, preventing flue gas leakage or the entry of outside air, meeting the requirements of the protective atmosphere, and preventing deflagration when the crushed lithium battery material is heated; the discharge port facilitates the discharge of processed material, realizing continuous production.

[0018] Furthermore, the cover plate is detachably connected to the guide cylinder by high-strength bolts, and the buffer block is fixedly connected to the cover plate by strong adhesive.

[0019] By adopting the above technical solution, the detachable connection of the high-strength bolts facilitates the subsequent disassembly of the cover plate. When the buffer block is damaged due to long-term impact, it can be removed and replaced together by disassembling the cover plate, which is convenient. The strong adhesive bonding can ensure that the buffer block and the cover plate are firmly connected, preventing the buffer block from falling off during the impact of the hammer ball, thus taking into account both maintenance convenience and structural stability.

[0020] Furthermore, the liner is detachably connected to the guide cylinder by high-strength bolts, and the guide cylinder is detachably connected to the fixing frame by high-strength bolts.

[0021] By adopting the above technical solution, the liner plate, as the component that directly bears the impact of the hammer ball, is prone to wear. The detachable connection of the high-strength bolts makes it easy to disassemble and replace the liner plate separately without disassembling the guide cylinder or the fixed frame as a whole, thus reducing maintenance costs and downtime. The detachable connection between the guide cylinder and the fixed frame makes it easy to replace the whole when the guide cylinder is damaged, thus improving the flexibility of equipment maintenance.

[0022] Furthermore, the magnetic plate is composed of multiple neodymium iron boron permanent magnets or multiple electromagnets.

[0023] By adopting the above technical solutions, if neodymium iron boron permanent magnets are selected, they can continuously generate stable magnetic attraction force, and the adsorption, detachment, and falling cycle of the hammer ball can be realized without additional power supply. This is suitable for continuous processing of lithium battery crushed materials and reduces energy consumption. If electromagnets are selected, the power supply can be controlled by external circuits to flexibly start and stop the vibration function. When there is less material in the kiln, the power supply can be cut off to stop the vibration, avoiding unnecessary component wear and tear, adapting to different production needs, and improving the flexibility of equipment use.

[0024] In summary, the present invention has the following main advantages: 1. This utility model, through the arrangement of a magnetic suction plate, a guide cylinder, and a hammer ball, uses an arc-shaped magnetic suction plate to adapt to the curvature of the kiln body. The magnetic suction force it generates only needs to be greater than the downward gravity of the hammer ball, eliminating the need for precise adjustment of the magnetic force and significantly reducing the difficulty of magnetic control. At the same time, the guide cylinder can stably guide the hammer ball, preventing it from falling off during its movement. This ensures that after the hammer ball revolves with the fixed frame to a position perpendicular to the ground above the kiln body and leaves the magnetic suction area of ​​the magnetic suction plate, it can fall stably along the guide cylinder and generate a vibration action. This improves the continuity and stability of the vibration action, thereby more efficiently reducing the material adhering to the inner wall of the kiln through vibration. The result is better performance and easier processing. 2. By installing a liner, this utility model allows the liner to directly withstand the impact force of the falling hammer ball, preventing direct contact between the hammer ball and the surface of the fixed frame. This reduces wear and scratches on the surface of the fixed frame caused by impact, effectively protecting the main structure of the fixed frame and extending its overall service life. Simultaneously, because the liner directly bears the impact load, it reduces the maintenance requirements of the fixed frame due to impact damage, lowering the overall operation and maintenance costs of the equipment and reducing damage to the kiln body and the fixed frame surface. 3. This utility model incorporates a buffer block made of rubber, which buffers the axial impact force generated by the hammer ball during its descent, preventing the hammer ball from directly colliding with the cover plate. This reduces structural damage to the cover plate and hammer ball caused by direct impact, extending their service life. Simultaneously, the buffering effect allows the impact force of the hammer ball to be transmitted more smoothly to the liner, reducing rigidity damage between components during impact, further improving the operational stability of the entire shock structure, reducing component replacement frequency, and minimizing cover plate breakage.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1:

[0030] A lithium battery recycling volatilization furnace, such as Figures 1-5As shown, the kiln includes a rotary kiln body 1 and a kiln body 2. The kiln body 1 is characterized by: a support 9 connected to one side of its top; a magnetic suction plate 10, which is arc-shaped, is installed inside the support 9; a fixing frame 11 is fixed to the outside of the kiln body 2; a guide cylinder 12 is connected to the top of the fixing frame 11; a cover plate 13 is connected to the top of the guide cylinder 12; a buffer block 14, made of rubber, is connected to the bottom center of the cover plate 13; a liner 15 passes through one side of the guide cylinder 12; a hammer ball 16 is placed inside the guide cylinder 12; the hammer ball 16 is in a rolling connection with the guide cylinder 12; and the hammer... The striking ball 16 abuts against the liner 15, and the striking ball 16 abuts against the buffer block 14. Multiple guide cylinders 12, cover plates 13, buffer blocks 14, liners 15 and striking balls 16 are provided. Multiple guide cylinders 12, cover plates 13, buffer blocks 14, liners 15 and striking balls 16 are arranged in a ring array. Since the fixing frame 11 is fixed outside the kiln body 2, when the kiln body 2 rotates, it will synchronously drive the fixing frame 11 to rotate. The guide cylinder 12 connected to the top of the fixing frame 11, as well as the cover plate 13, buffer block 14, liner 15 on the guide cylinder 12 and the striking ball 16 placed inside, will revolve accordingly. At this time, the arc-shaped magnetic suction plate 10 inside the support 9 on one side of the top of the rotary kiln body 1 begins to function. When the hammer ball 16 revolves with the guide cylinder 12 to the area near the magnetic suction plate 10, the magnetic attraction generated by the magnetic suction plate 10 attracts the hammer ball 16, causing the hammer ball 16 to continue revolving with the guide cylinder 12 and remain in a position near the cover plate 13. The cover plate 13 prevents the hammer ball 16 from axially detaching from the guide cylinder 12, and the hammer ball 16 abuts against the buffer block 14. The buffer block 14 is made of rubber material, which can buffer the axial impact force of the hammer ball 16 and reduce the direct impact between the hammer ball 16 and the cover plate 13. To prevent structural damage, when the hammer ball 16 revolves with the guide cylinder 12 to a position above the kiln body 2 perpendicular to the ground, the hammer ball 16 detaches from the magnetic attraction area of ​​the magnetic suction plate 10 and rolls downward along the inside of the guide cylinder 12 under its own gravity. The guide cylinder 12 plays a stabilizing and guiding role for the hammer ball 16 to prevent it from falling off. Subsequently, the hammer ball 16 falls downward under the influence of gravity and collides with the liner plate 15. The impact on the liner plate 15 generates vibration, which is transmitted to the fixed frame 11 and the kiln body 2 in sequence, and finally acts on the lithium battery crushed material adhering to the inner wall of the kiln body 2, reducing the adhesion of the material to the inner wall of the kiln body 2.

[0031] See Figure 1In the above embodiment, the kiln body 2 extends through both sides of the rotary kiln body 1. One end of the kiln body 2 is connected to a smoke chamber 3, the top of which is connected to a smoke exhaust port 5. A feed inlet 4 is connected to one side of the smoke chamber 3. The other end of the kiln body 2 is connected to a kiln head 6. A seal 7 connects the kiln head 6 and the smoke chamber 3 to the kiln body 2. A discharge port 8 is connected to the bottom of the kiln head 6. Crushed lithium battery material enters the kiln body 2 through the feed inlet 4 on one side of the smoke chamber 3. The kiln body 2 rotates under the drive of the internal drive structure of the rotary kiln body 1. Simultaneously, the kiln head 6 at one end of the kiln body 2 and the smoke chamber 3 are connected to the kiln head 6. The sealing structure 7 between chamber 3 and kiln body 2 maintains the airtightness of the kiln environment and prevents leakage of flue gas or materials. During the rotation of kiln body 2, the lithium battery crushed material inside is heated along with the movement of kiln body 2 to achieve organic matter decomposition. In addition, the external protective atmosphere device will input nitrogen protective gas into kiln body 2 to prevent the lithium battery crushed material from contacting oxygen during heating and causing deflagration or other phenomena. The generated flue gas is discharged through the exhaust port 5 at the top of the flue chamber 3, and the material after heat treatment is discharged from the discharge port 8 at the bottom of the kiln head 6.

[0032] Example 2:

[0033] Based on the above embodiment one, the following settings are now made for ease of maintenance.

[0034] See Figures 2-5 In the above embodiment, the cover plate 13 is detachably connected to the guide cylinder 12 by high-strength bolts, and the buffer block 14 is fixedly connected to the cover plate 13 by strong adhesive. The liner plate 15 is detachably connected to the guide cylinder 12 by high-strength bolts, and the guide cylinder 12 is detachably connected to the fixing frame 11 by high-strength bolts. If the buffer block 14 needs to be replaced, since the cover plate 13 is detachably connected to the guide cylinder 12 by high-strength bolts, the high-strength bolts can be removed first to remove the cover plate 13 from the top of the guide cylinder 12. The cover plate 13 and the buffer block 14 are bonded by strong adhesive, so the buffer block can be removed when the cover plate 13 is removed. 14 can be removed and replaced together, and the hammer ball 16 can also be removed and replaced from inside the guide cylinder 12. If the liner 15 needs to be replaced, since the liner 15 is connected to the guide cylinder 12 by high-strength bolts, the liner 15 can be directly pulled out horizontally to complete the replacement. If the guide cylinder 12 needs to be replaced, the liner 15 must be removed in the above manner first, and then the high-strength bolts between the guide cylinder 12 and the fixing frame 11 can be removed to disassemble and replace the guide cylinder 12. During the maintenance and replacement process, it is necessary to ensure that the guide cylinder 12 and the cover plate 13 to be maintained are rotated to the outer surface area that is not inside the bracket 9 so as to facilitate smooth operation.

[0035] Example 3:

[0036] Based on the above embodiment one, the following settings are now adopted to be applicable to different situations.

[0037] See Figures 2-4In the above embodiments, the magnetic chuck 10 is composed of multiple neodymium iron boron permanent magnets or multiple electromagnets. If the magnetic chuck 10 is composed of multiple neodymium iron boron permanent magnets, the permanent magnets can continuously generate a stable magnetic attraction force, and can attract the hammer ball 16 for a long time without additional power. This allows the hammer ball 16 to continuously complete the cycle of attraction, detachment, falling, and vibration as it revolves with the guide cylinder 12, thus achieving continuous vibration work. If the magnetic chuck 10 is composed of multiple electromagnets, the power on and off of the electromagnets can be controlled by an external circuit. When powered on, the electromagnets generate a magnetic attraction force to attract the hammer ball 16 to achieve the vibration cycle. When powered off, the magnetic attraction force disappears, the hammer ball 16 is no longer attracted, and the vibration work stops, thus flexibly controlling the start and stop of the hammering work.

[0038] The implementation principle of this utility model is as follows: First, the crushed lithium battery material enters the kiln body 2 from the feed port 4 on one side of the smoke chamber 3. The kiln body 2 rotates under the drive structure inside the rotary kiln body 1. At the same time, the sealing structure 7 between the kiln head 6 at one end of the kiln body 2 and the smoke chamber 3 and the kiln body 2 maintains the airtightness of the kiln environment and avoids leakage of flue gas or materials. During the rotation of the kiln body 2, the crushed lithium battery material inside is heated along with the movement of the kiln body 2 to achieve the decomposition of organic matter. In addition, the external protective atmosphere device will input nitrogen protective gas into the kiln body 2 to prevent the crushed lithium battery material from contacting oxygen during heating and causing deflagration or other phenomena. The generated flue gas is discharged through the exhaust port 5 at the top of the smoke chamber 3. The material after heat treatment is discharged from the discharge port 8 at the bottom of the kiln head 6. Meanwhile, since the fixing frame 11 is fixed to the outside of the kiln body 2, when the kiln body 2 rotates, it will synchronously drive the fixing frame 11 to rotate. The guide cylinder 12 connected to the top of the fixing frame 11, as well as the cover plate 13, buffer block 14, liner plate 15 and the hammer ball 16 placed inside the guide cylinder 12, will also revolve. At this time, the arc-shaped magnetic suction plate 10 inside the support 9 on one side of the top of the rotary kiln body 1 starts to work. When the hammer ball 16 revolves with the guide cylinder 12 to the area close to the magnetic suction plate 10, the magnetic suction force generated by the magnetic suction plate 10 will attract the hammer ball 16, so that the hammer ball 16 continues to revolve with the guide cylinder 12 and is maintained in the position close to the cover plate 13. The cover plate 13 prevents the hammer ball 16 from axially detaching from the guide cylinder 12. The hammer ball 16 abuts against the buffer block 14. The buffer block 14 is made of rubber material, which can buffer the axial impact force of the hammer ball 16 and reduce the structural damage caused by the direct impact of the hammer ball 16 with the cover plate 13. When the hammer ball 16 revolves with the guide cylinder 12 to a position above the kiln body 2 perpendicular to the ground, the hammer ball 16 detaches from the magnetic attraction area of ​​the magnetic suction plate 10 and rolls downward along the inside of the guide cylinder 12 under its own gravity. The guide cylinder 12 plays a stabilizing and guiding role for the hammer ball 16 to prevent it from falling off. Subsequently, the hammer ball 16 falls downward under the influence of gravity and collides with the liner plate 15. The impact on the liner plate 15 generates vibration, which is transmitted to the fixing frame 11 and the kiln body 2 in sequence. Finally, it acts on the lithium battery crushed material adhering to the inner wall of the kiln body 2, reducing the adhesion of the material to the inner wall of the kiln body 2. When individual components need to be disassembled, replaced, or maintained, if the buffer block 14 needs to be replaced, since the cover plate 13 is detachably connected to the guide cylinder 12 via high-strength bolts, the high-strength bolts can be removed first to remove the cover plate 13 from the top of the guide cylinder 12. The cover plate 13 and the buffer block 14 are bonded together with strong adhesive, so the buffer block 14 can be removed and replaced at the same time when the cover plate 13 is removed. At the same time, the hammer ball 16 can also be removed and replaced from inside the guide cylinder 12. If the liner 15 needs to be replaced, since the liner 15 is detachably connected to the guide cylinder 12 via high-strength bolts, the liner 15 can be directly pulled out horizontally to complete the replacement. If the guide cylinder 12 needs to be replaced, the liner 15 must be removed first in the above manner, and then the high-strength bolts between the guide cylinder 12 and the fixing frame 11 can be removed to disassemble and replace the guide cylinder 12. During the maintenance and replacement process, it is necessary to ensure that the guide cylinder 12 and the cover plate 13 to be maintained are rotated to the outer surface area that is not inside the bracket 9 for smooth operation. Furthermore, depending on the type of magnetic chuck 10, if the magnetic chuck 10 is composed of multiple neodymium iron boron permanent magnets, the permanent magnets can continuously generate a stable magnetic attraction force, and can attract the hammer ball 16 for a long time without additional power. This allows the hammer ball 16 to continuously complete the cycle of attraction, detachment, falling, and vibration as it revolves with the guide cylinder 12, thus achieving continuous vibration work. If the magnetic chuck 10 is composed of multiple electromagnets, the electromagnets can be energized and de-energized through an external circuit. When energized, the electromagnets generate a magnetic attraction force to attract the hammer ball 16 to achieve the vibration cycle. When de-energized, the magnetic attraction force disappears, the hammer ball 16 is no longer attracted, and the vibration work stops, thus flexibly controlling the start and stop of the hammering work.
