Description

Technical Field

[0001] This application relates to the field of magnet recycling devices, and more particularly to a neodymium iron boron magnet waste recycling device. Background Technology

[0002] Neodymium iron boron (NdFeB) is a high-performance permanent magnet material, known as the "King of Magnets" for its excellent magnetic properties. It is mainly composed of rare earth elements neodymium, iron, and boron, and has high magnetic energy product and coercivity, which makes it widely used in modern industry and electronic technology. After some equipment is scrapped, the NdFeB magnets inside can be recycled and reused. During the recycling process, the NdFeB magnets need to be crushed by a crusher.

[0003] However, in the process of crushing magnetic blocks, traditional crushers require workers to manually shovel the magnetic blocks with a shovel and then throw them into the crusher's feed hopper. Since the feed hopper is located at a high position, workers need to shovel the magnetic blocks to a high height each time, which is not only a waste of physical strength, but also poses a certain danger as the magnetic blocks may fall from a height and hit the workers. Utility Model Content

[0004] In order to save physical effort when adding magnetic blocks into the crusher and improve operational safety, this application provides a neodymium iron boron magnet waste recycling device.

[0005] This application provides a neodymium iron boron magnet waste recycling device, which adopts the following technical solution:

[0006] A neodymium iron boron magnet waste recycling device includes a crusher body with a conveying structure. The conveying structure includes a connecting frame and rollers. The connecting frame is rotatably connected to the crusher body, and two rollers are rotatably connected to the connecting frame. The two rollers are wound with the same conveyor belt. A motor is installed on the connecting frame, and the output shaft of the motor is fixedly connected to one of the rollers. A first connecting seat is fixedly connected to the connecting frame, and a connecting shaft is rotatably connected to the first connecting seat. Two support rods are fixedly connected to the connecting shaft, and one end of each support rod has a locking slot. A second connecting seat is fixedly connected to the crusher body, and a support shaft is fixedly connected to the second connecting seat. The support rods and the support shaft engage with each other. A collection structure is provided at the bottom of the crusher body.

[0007] By adopting the above technical solution, during use, the motor can be started, and the output shaft of the motor will rotate, driving one of the rollers to rotate. The rotation of the roller will drive the conveyor belt to move. Then, the magnetic block can be scooped up with a shovel and placed at one end of the conveyor belt. The magnetic block will move with the conveyor belt to the feed hopper of the crusher body, and then fall into the interior of the crusher body for crushing under the action of gravity. Since one end of the conveyor belt is lower, it avoids the need for workers to scoop the magnetic block to a higher height, thus saving physical strength. At the same time, it also avoids the magnetic block falling from a height and hitting the workers, thereby improving the safety of operation. When the conveyor belt is not needed to transport the magnetic block, the two support rods can be detached from the support shaft. Then, the support rods can be rotated toward the connecting frame to bring the two support rods close to the connecting frame. Then, the connecting frame can be rotated toward the crusher body to bring the connecting frame and the crusher body close together. At this time, the conveyor belt can be stored, thus saving space and making the transportation and storage of the device easier.

[0008] Optionally, the bayonet has a U-shaped cross-section, and the conveyor belt is inclined.

[0009] By adopting the above technical solution, the magnetic block can be transported from a low position to a high position by a conveyor belt.

[0010] Optionally, the conveyor belt is fixedly connected with multiple protrusions, which are equidistantly distributed.

[0011] By adopting the above technical solution, the convex strip can prevent the magnetic block from sliding on the surface of the conveyor belt, thereby improving the stability during conveying.

[0012] Optionally, a guide plate is fixedly connected to the connecting frame, and the guide plate is inclined.

[0013] By adopting the above technical solution, the magnetic blocks can be guided when they are placed on the conveyor belt.

[0014] Optionally, the second connecting seat is provided with a limiting structure, the limiting structure including a plug rod and a return spring, the plug rod being slidably connected to the second connecting seat, and the plug rod engaging with one of the support rods.

[0015] By adopting the above technical solution, when the support rod is engaged with the support shaft, the insertion rod and one of the support rods can be engaged, thereby preventing the support rod from detaching from the support shaft and effectively improving the stability of use.

[0016] Optionally, a return spring is sleeved on the outside of the insertion rod, one end of the return spring is fixedly connected to the insertion rod, and the other end of the return spring is fixedly connected to the second connecting seat.

[0017] By adopting the above technical solution, the insertion rod can always be engaged with the support rod under the action of the return spring.

[0018] Optionally, one end of the insertion rod has a T-shaped cross-section, and the other end of the insertion rod has a trapezoidal cross-section.

[0019] By adopting the above technical solution, it can play a guiding role when the insert rod and the support rod are engaged.

[0020] Optionally, the collection structure includes a collection box and a handle. The collection box is located at the bottom of the crusher body, a handle is fixedly connected to one side of the collection box, and four casters are installed at the bottom of the collection box.

[0021] By adopting the above scheme, the crushed magnet powder can fall into the inside of the collection box for centralized collection. The collection box can be easily moved by setting four moving wheels and a handle.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When it is necessary to put the magnetic block into the inside of the crusher for crushing, the magnetic block can be scooped up with a shovel and placed at one end of the conveyor belt. The magnetic block will move with the conveyor belt to the feed hopper of the crusher body, and then fall into the inside of the crusher body for crushing under the action of gravity. Since the position of one end of the conveyor belt is low, it avoids the need for the operator to scoop the magnetic block to a high height, thus saving physical strength. At the same time, it can also prevent the magnetic block from falling from a height and hitting the operator, thereby improving the safety of operation.

[0024] 2. When the conveyor belt is not needed for transporting the magnetic blocks, the two support rods can be detached from the support shaft. Then, the support rods can be rotated toward the connecting frame to bring the two support rods together with the connecting frame. Then, the connecting frame can be rotated toward the crusher body to bring the connecting frame and the crusher body together. At this time, the conveyor belt can be stored, which saves space and makes the device easier to transport and store.

[0025] 3. The crushed magnetite powder can fall into the inside of the collection structure for centralized collection, which facilitates the transfer of the crushed magnetite powder. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a neodymium iron boron magnet waste recycling device. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A neodymium iron boron magnet waste recycling device includes a crusher body 1, on which a conveying structure 2 is provided.

[0035] The magnetic block moves along with the conveyor belt 203 to the feed hopper of the crusher body 1, and then falls into the interior of the crusher body 1 under the action of gravity for crushing. Since one end of the conveyor belt 203 is lower, it avoids the need for workers to scoop the magnetic block to a higher height, thus saving physical strength. At the same time, it can also prevent the magnetic block from falling from a height and hitting the workers, thereby improving the safety of operation. During the process of the conveyor belt 203 driving the magnet to move, multiple protrusions 204 can be set to prevent the magnet from sliding on the conveyor belt 203, thereby effectively improving the stability during conveying.

[0036] When the conveyor belt 203 is not needed for conveying the magnetic blocks, one of the support rods 209 can be moved away from the support shaft 211. Since both support rods 209 are fixedly connected to the connecting shaft 208, when one support rod 209 moves, it will drive the other support rod 209 to move synchronously. After both support rods 209 are disengaged from the support shaft 211, they can be rotated toward the connecting frame 201 so that the two support rods 209 are close to the connecting frame 201. Then, the connecting frame 201 is rotated toward the crusher body 1 so that the connecting frame 201 and the crusher body 1 are close together. At this time, the conveyor belt 203 is stored, which saves space and makes the transportation and storage of the device more convenient.

[0037] Reference Figure 1 As shown, a guide plate 206 is fixedly connected to the connecting frame 201, and the guide plate 206 is inclined.

[0038] After multiple magnetic blocks are scooped up with a shovel, they can be placed on the guide plate 206. Once the magnetic blocks fall onto the guide plate 206, they will automatically slide onto the conveyor belt 203 under the action of gravity. This serves to guide the magnetic blocks and prevent them from falling directly onto the conveyor belt 203 and causing damage, thus effectively improving the safety of use.

[0039] Reference Figure 1 , Figure 2 and Figure 6 As shown, the second connecting seat 212 is provided with a limiting structure 3, which includes a plug rod 301 and a return spring 302. The plug rod 301 is slidably connected to the second connecting seat 212. The plug rod 301 is engaged with one of the support rods 209. The return spring 302 is sleeved on the outside of the plug rod 301. One end of the return spring 302 is fixedly connected to the plug rod 301, and the other end of the return spring 302 is fixedly connected to the second connecting seat 212. The cross-section of one end of the plug rod 301 is T-shaped, and the cross-section of the other end of the plug rod 301 is trapezoidal.

[0040] When the two support rods 209 are engaged with the support shaft 211, the return spring 302 can engage the insertion rod 301 with one of the support rods 209. This prevents the support rods 209 from detaching from the support shaft 211 and losing support for the connecting frame 201 during the process of the two support rods 209 supporting the connecting frame 201, thus effectively improving the stability of use. When it is necessary to store the conveyor belt 203, the insertion rod 301 can be pulled, and the return spring 302 will extend. When one end of the insertion rod 301 is not engaged with one of the support rods 209, the support rod 209 can be moved to detach from the support shaft 211, thereby causing the two support rods 209 to lose support for the connecting frame 201. Then, the connecting frame 201 can be rotated toward the crusher body 1 to store the conveyor belt 203.

[0041] Reference Figure 1 and Figure 3 As shown, the collection structure 4 includes a collection box 401 and a handle 402. The bottom of the crusher body 1 is provided with a collection box 401. A handle 402 is fixedly connected to one side of the collection box 401. Four casters 403 are installed at the bottom of the collection box 401.

[0042] The crushed magnetic powder can fall into the collection box 401 for centralized collection. Since the bottom of the collection box 401 is equipped with four moving wheels 403, the collection box 401 can be moved by pulling the handle 402, which facilitates the transfer of magnetic powder.

[0043] This application discloses an implementation principle of a neodymium iron boron magnet waste recycling device: During use, the motor 205 is started, and the output shaft of the motor 205 rotates, driving one of the roller shafts 202 to rotate. The rotation of the roller shaft 202 drives the conveyor belt 203 to move, and then multiple magnetic blocks can be scooped up and placed on the guide plate 206. When the magnetic blocks fall onto the guide plate 206, they can automatically slide down to one end of the conveyor belt 203 under the action of gravity, thereby guiding the magnetic blocks and preventing them from directly falling onto the conveyor belt. The magnetic blocks falling onto the conveyor belt 203, which would otherwise damage the conveyor belt 203, effectively improve operational safety. The magnetic blocks will move along with the conveyor belt 203 to the feed hopper of the crusher body 1, and then fall into the crusher body 1 under gravity for crushing. Because one end of the conveyor belt 203 is positioned low, it avoids the need for workers to scoop the magnetic blocks to a higher height, thus saving physical effort and preventing the magnetic blocks from falling from a height and injuring workers, thereby improving operational safety. The magnetic blocks are driven by the conveyor belt 203... During the process, multiple protrusions 204 can be set to prevent the magnet from sliding on the conveyor belt 203, thereby effectively improving the stability during conveying. The crushed magnet powder can fall into the collection box 401 for centralized collection. Since the bottom of the collection box 401 is equipped with four moving wheels 403, the collection box 401 can be moved by pulling the handle 402, which facilitates the transfer of the magnet powder. When the conveyor belt 203 is not needed for conveying the magnetic blocks, one of the support rods 209 can be moved away from the support shaft 211. Since the two support rods All 209 are fixedly connected to the connecting shaft 208. Therefore, when one of the support rods 209 moves, it will drive the other support rod 209 to move synchronously. After both support rods 209 are disengaged from the support shaft 211, they can be rotated toward the connecting frame 201 to bring the two support rods 209 together with the connecting frame 201. Then, the connecting frame 201 is rotated toward the crusher body 1 to bring the connecting frame 201 and the crusher body 1 together. At this time, the conveyor belt 203 is stored, which saves space and makes the transportation and storage of the device more convenient.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
