Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, specifically to an automatic recycling device for neodymium iron boron waste. Background Technology

[0002] In the field of NdFeB waste recycling, the limitations of traditional methods are becoming increasingly apparent, especially in terms of processing efficiency and recycling effectiveness. With the development of technology and the widespread application of NdFeB materials in new energy vehicles, wind power generation, electronic equipment and other fields, the amount of waste generated in the production process has increased dramatically, and the requirements for waste recycling technology have also increased. However, the recycling methods currently widely used in the market, such as relying on manual sorting or simple mechanical equipment for preliminary processing, are obviously unable to meet the needs of efficient and accurate recycling.

[0003] However, among the existing methods for collecting NdFeB waste, wet recycling, pyrometallurgical recycling, electrochemical methods, and ionic liquid methods are all common treatment technologies. Compared with wet recycling and pyrometallurgical recycling, magnetic attraction technology does not generate a large amount of wastewater, waste gas, or solid waste, reducing the risk of secondary pollution. Moreover, the crushing step helps to refine the waste and increase the surface area of ​​magnetic particles, thereby improving the efficiency and effect of magnetic attraction. Therefore, this paper uses magnetic attraction technology to quickly separate the magnetic components in NdFeB waste. In magnetic attraction technology, relatively primitive crushing methods such as hammering or impact crushing are often used. Although the waste can be crushed by physical impact, it has high energy consumption, high noise, and the crushing effect is difficult to control. Due to the uneven force distribution on the waste during the crushing process, the particle size distribution of the final product is wide, which not only increases the difficulty of subsequent screening and sorting, but also directly affects the quality and value of the recycled materials. Secondly, in terms of waste mixing and magnetic material separation, different components or particles in the waste residue are often difficult to achieve uniform distribution during the mixing process due to differences in physical properties, density, etc. This not only affects the efficiency and effectiveness of subsequent processing steps, but also leads to an increase in the impurity content in the recycled materials, reducing the overall quality. At the same time, since the movement trajectory of the waste residue in the equipment is relatively simple and singular, the contact opportunities between magnetic materials and magnetic separators are limited, and the contact strength and frequency are difficult to guarantee. This directly leads to low adsorption and separation efficiency of magnetic materials, and it is easy to miss and waste. In addition, the agglomeration or clustering of waste residue is also a major problem. They not only increase the difficulty of capturing magnetic materials, but also have an adverse effect on the performance and lifespan of magnetic separators.

[0004] Therefore, an automatic recycling device for NdFeB waste is proposed. Summary of the Invention

Adaptive helical gears are fixedly connected to the ends of the two rotating shafts near the connecting shaft. Rotating wheels are fixedly connected to the ends of the two rotating shafts away from the connecting shaft. A conveyor belt is drivenly connected to the outer surface of the two rotating wheels.

[0009] Preferably, the recycling component includes a rotating housing, which is rotatably connected to the inside of the discharge housing.

[0010] Preferably, the drive gear is drivably mounted on the built-in drive motor, the built-in drive motor is electrically connected to an external controller, the drive gear meshes with the meshing gear, the first pulverizing disc and the second pulverizing disc mesh with each other, the linkage block is connected to the stirring column via a conveyor belt, and the two ends of the outer surface of the stirring column away from the stirring rod are fixedly connected with spiral plates, the arc surface of the spiral plates away from the outer surface of the stirring column is set in the shape of blades.

[0011] Preferably, the recycling shell and the feeding shell are internally connected, the rotating disk is driven and mounted on an external drive motor, the external drive motor is electrically connected to an external controller, the rotating helical gear meshes with the matching helical gear, the connecting shaft is rotatably connected through the rotating helical gear, and the rotating wheel one is connected to the rotating wheel two through the conveyor belt two.

[0012] Preferably, the rotating housing is made of metal, and magnetic separators are provided on both the inner and outer surfaces of the rotating housing.

[0013] Preferably, the neodymium iron boron waste is adsorbed onto the surface of the rotating housing by a magnetic separator inside the rotating housing.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the meshing of crushing disc one and crushing disc two in the crushing assembly, the waste material entering the feed housing is crushed, ensuring that the waste material is fully squeezed and sheared when passing through these two crushing discs, thereby achieving a highly efficient crushing effect. The setting of the concentrating shell allows the waste material to fall accurately between crushing disc one and crushing disc two. When the waste material enters the crushing area through the guidance of the concentrating shell, its movement trajectory is more stable and orderly, reducing the scattering and accumulation of waste material inside the equipment, making the crushing process more continuous and efficient. The device includes a stirring rod installed above the first and second grinding discs. The rotation of the stirring rod ensures full contact and collision between the waste material and the grinding discs, preventing excessive waste accumulation in certain areas from reducing grinding efficiency and thus improving the grinding effect. At the same time, spiral plates are installed at both ends of the stirring column away from the stirring rod. The design of the spiral plates can increase the turbulence effect during the stirring process, preventing waste accumulation in local areas and further improving the grinding effect. In addition, the edge design of the spiral plates can also perform initial crushing of larger waste materials, which helps the waste materials to be pre-processed before entering the main grinding area. 2. The rotating disc drives the rotating support to rotate, which in turn drives the discharge shell to rotate, causing the waste residue inside to rotate. This achieves preliminary mixing of the waste residue, which helps to make the different components or particles in the waste residue more evenly distributed, laying the foundation for subsequent processing steps. At the same time, through the meshing of the rotating helical gear and the matching helical gear, the waste residue undergoes a more complex motion trajectory as the discharge shell rotates and also rotates on its own axis, further enhancing the mixing effect. The movement of the waste residue can enhance the contact frequency and intensity between magnetic materials and the magnetic separator, making it easier for magnetic materials to be adsorbed and separated. At the same time, the uniform mixing of the waste residue makes the distribution of NdFeB waste more even in the waste residue, thereby improving the efficiency of the magnetic separator in adsorbing NdFeB waste and reducing omissions and waste. The rotation and self-rotation of the waste residue also help to break up the clumps or agglomerates in the waste residue, making it easier for magnetic materials to be captured by the magnetic separator.

[0020] The rotating assembly 3 includes a recycling housing 31, which is fixedly connected to the bottom of the feeding housing 1. An outlet 32 ​​is provided on the outer surface of the recycling housing 31. A connecting rod 34 is rotatably connected through the side of the recycling housing 31 away from the outlet 32. A rotating disk 33 is fixedly connected to the end of the connecting rod 34 away from the outlet 32. A rotating helical gear 35 is fixedly connected to the inner surface of the recycling housing 31. A connecting shaft 36 is fixedly connected to the end of the connecting rod 34 away from the rotating disk 33. A rotating bracket 37 is fixedly connected to the side of the connecting shaft 36 away from the rotating helical gear 35. The outer surfaces of the rotating bracket 37 rotate on both sides. The system is connected to a rotating shaft 38. Each of the two rotating shafts 38 is fixedly connected to a matching helical gear 39 at one end near the connecting shaft 36. Each of the two rotating shafts 38 is fixedly connected to a rotating wheel 310 at one end away from the connecting shaft 36. Each of the two rotating wheels 310 is connected to a conveyor belt 311 on its outer surface. Each of the two rotating supports 37 is rotatably connected to a connecting column 312 on both sides at one end away from the connecting shaft 36. A discharge housing 314 is fixedly connected between the two connecting columns 312. A feed chute 315 is provided on the top of the discharge housing 314. Each of the two connecting columns 312 is fixedly connected to a rotating wheel 313 at one end away from each other.

[0021] The recycling component 4 includes a rotating housing 41, which is rotatably connected to the inside of the discharge housing 314. The outer surface of the rotating housing 41 has square slots 42 arranged in a circular array at equal intervals. Fixed rods 43 are fixedly connected to both sides of the inner cavity of the rotating housing 41.

[0022] The concentrator shell 21 is shaped as an arc surface that tapers from top to bottom, allowing waste to slide or roll naturally along the arc surface when it falls into or enters the area. This guiding effect helps the waste enter the crushing stage more smoothly, reducing the risk of jamming or clogging. The drive gear 24 is drivably mounted on the built-in drive motor, which is electrically connected to an external controller. The drive gear 24 meshes with the meshing gear 27. The rotation of the drive gear 24 drives the meshing gear 27 to rotate. The first crushing disc 25 and the second crushing disc 28 mesh with each other. The meshing of the first crushing disc 25 and the second crushing disc 28 crushes the waste, making it easier to separate and extract the useful components in the waste. The linkage block 29 is connected to the stirring column 212 via the first conveyor belt 210. Spiral plates are fixedly connected to both ends of the outer surface of the stirring column 212 away from the stirring rod 213. The arc surface of the spiral plates away from the outer surface of the stirring column 212 is blade-shaped.

[0023] The recycling shell 31 is internally connected to the feeding shell 1. The rotating disk 33 is driven and mounted on an external drive motor. The external drive motor is electrically connected to an external controller. The rotating helical gear 35 meshes with the matching helical gear 39. The connecting shaft 36 passes through and is rotatably connected inside the rotating helical gear 35. The rotation of the rotating helical gear 35 drives the matching helical gear 39 to rotate. The rotating wheel 310 is connected to the rotating wheel 313 via the conveyor belt 311.

[0024] The rotating housing 41 is made of iron, which has good mechanical strength and corrosion resistance. Magnetic separators are installed on both the inner and outer surfaces of the rotating housing 41. The magnetic separators utilize magnetic force to efficiently separate magnetic substances from metal waste. The fixed rod 43 is also made of iron, which has good magnetic conductivity and can shield the influence of external stray magnetic fields on the internal magnetic field of the magnetic separator to a certain extent. This helps to maintain the stability and purity of the internal magnetic field of the magnetic separator, thereby improving the magnetic separation effect. The magnetic separator inside the rotating housing 41 is electrically connected to an external power supply via an external controller, thereby realizing the automated control of the magnetic separator.

[0025] The NdFeB waste is adsorbed onto the surface of the rotating housing 41 by the magnetic separator inside the rotating housing 41, which reduces the loss of waste during the recycling process and improves the recycling efficiency. The waste adsorbed on the surface of the rotating housing 41 can be directly carried out in the next recycling process.

[0026] The working principle of the present invention, based on the above implementation, is as follows: In the initial state: the sealing cover 11 does not block the top of the feed housing 1, and the feed trough 315 is located directly below the feed housing 1.

[0027] During work: The waste material is crushed and processed. The operator pours the waste to be recycled into the feed housing 1 from the top. The waste then falls along the shape of the collection shell 21 between the first crushing disc 25 and the second crushing disc 28. Guided by the collection shell 21, the waste moves more smoothly and orderly into the crushing area, reducing the scattering and accumulation of waste inside the equipment, making the subsequent crushing process more continuous and efficient. The operator then manually rotates the sealing cover 11 to seal the top of the feed housing 1, preventing the waste from splashing out of the equipment during crushing. Afterwards, the operator electrically controls the built-in drive motor via an external controller. The drive motor drives the drive gear 24 to rotate, which in turn drives the drive column. Rotation of drive column 23 drives the first crushing disc 25 to rotate. Simultaneously, because drive gear 24 meshes with meshing gear 27, the rotation of drive gear 24 drives meshing gear 27 to rotate in the opposite direction. The reverse rotation of meshing gear 27 drives rotating column 26 to rotate in the opposite direction. The reverse rotation of rotating column 26 drives second crushing disc 28 to rotate in the opposite direction. At this time, since first crushing disc 25 rotates in the forward direction and second crushing disc 28 rotates in the reverse direction, and crushing disc 25 and second crushing disc 28 mesh with each other, the waste material entering the feed housing 1 is crushed. This ensures that the waste material is subjected to sufficient compression and shearing action when passing through these two crushing discs, thereby achieving a highly efficient crushing effect and quickly breaking the waste material into smaller particles. Compared with other crushing methods, such as hammer crushing or impact crushing, the meshing crushing method can utilize mechanical energy more effectively and reduce energy consumption. In the above, the meshing gear 27 rotates, driving the linkage block 29 to rotate. The rotation of the linkage block 29 drives the stirring column 212 to rotate inside the limiting shell 211 through the transmission of the conveyor belt 210. The rotation of the stirring column 212 drives the stirring rod 213 to rotate around the center of the stirring column 212. At this time, the rotation of the stirring rod 213 will stir the crushed waste. The rotation of the stirring rod 213 will ensure full contact and collision between the waste and the crushing disc, avoiding the decrease in crushing efficiency due to excessive accumulation of waste in some areas, thereby improving the crushing effect.

[0028] Waste materials are recycled and processed. Since the feed trough 315 is located directly below the feed housing 1, the crushed waste will fall from the inside of the feed housing 1 and the feed trough 315 into the discharge housing 314 under the action of gravity. At this time, the waste has changed from large solid pieces to small fragments that are easy to handle, which facilitates the subsequent processing steps. At this time, the operator starts the magnetic separator electrically through the external controller. After the magnetic separator is started, it relies on the electric triggering of the magnetic force. Its internal magnetic system responds quickly and generates a strong magnetic field. This magnetic field has a strong attraction to the magnetic material neodymium iron boron in the waste and can effectively separate them from the non-magnetic material. Subsequently, the operator electrically controls the external drive motor to start via an external controller. The external drive motor drives the rotating disk 33 to rotate, which in turn drives the connecting rod 34 to rotate. The connecting rod 34 then drives the connecting shaft 36 to rotate, which in turn drives the rotating bracket 37 to rotate. The rotating bracket 37 then drives the connecting columns 312 on both sides to rotate around the center of the rotating bracket 37. The rotation of the connecting columns 312 on both sides then drives the discharge shell 314 to rotate around the center of the rotating bracket 37. The rotation of the discharge shell 314 around the center of the rotating bracket 37 initially mixes the waste residue inside, which helps to make the different components or particles in the waste residue more evenly distributed, laying the foundation for subsequent processing steps and further allowing the magnetic material to have more sufficient contact with the magnetic separator. Furthermore, the rotation of the rotating bracket 37 drives the rotating shaft 38 to rotate around the connecting shaft 36. The rotation of the rotating shaft 38 drives the matching helical gear 39 to rotate around the connecting shaft 36. The rotation of the matching helical gear 39 around the connecting shaft 36 causes the matching helical gear 39 to be displaced. At the same time, since the matching helical gear 39 meshes with the rotating helical gear 35, after the matching helical gear 39 is displaced, it will rotate due to the meshing with the rotating helical gear 35. That is, the matching helical gear 39 rotates around the connecting shaft 36 while rotating on its own axis. The rotation of the matching helical gear 39 drives the rotating shaft 38 to rotate inside the rotating bracket 37. The rotation of the rotating shaft 38 drives the rotating wheel 310. The rotation of rotating wheel 310 drives rotating wheel 313 through the transmission of conveyor belt 311. The rotation of rotating wheel 313 drives the connecting column 312 to rotate. The rotation of connecting column 312 drives the discharge shell 314 to rotate around the connecting column 312. The rotation of discharge shell 314 around the connecting column 312 causes the waste residue inside to undergo a more complex motion trajectory, further enhancing the mixing effect. As discharge shell 314 rotates, the rotating shell 41 inside discharge shell 314 will be affected by multiple rotational forces and move inside discharge shell 314, thereby increasing the contact frequency and intensity between magnetic materials and magnetic separator. Finally, as the discharge shell 314 rotates, the feed trough 315 will rotate to the side away from the feed shell 1. The non-magnetic materials in the waste will fall to the bottom of the inner cavity of the recycling shell 31 under the action of gravity. Then, the operator will collect and process the non-magnetic waste. After the non-magnetic waste is collected, the operator will electrically control the magnetic separator to shut down through the external controller. At this time, the magnetic materials will no longer be attracted by the magnetic force. Subsequently, they will fall to the bottom of the inner cavity of the recycling shell 31 under the action of gravity and be collected by the operator. The movement of the waste can enhance the contact frequency and force between the magnetic materials and the magnetic separator, making it easier for the magnetic materials to be adsorbed and separated. At the same time, the uniform mixing of the waste makes the distribution of NdFeB waste in the waste more uniform, thereby improving the efficiency of the magnetic separator in adsorbing NdFeB waste and reducing omissions and waste. The rotation and self-rotation of the waste also help to break up the clumps or agglomerates in the waste, making it easier for the magnetic materials to be captured by the magnetic separator.
