Description

Technical Field

[0001] This invention relates to the field of rare earth recycling, and more specifically, to a recycling device for recovering rare earth metals from rare earth metal slag. Background Technology

[0002] Rare earth metals, also known as rare earth elements, are a collective term for 17 elements in Group IIIB of the periodic table, including scandium, yttrium, and the lanthanides. Rare earths are mainly used in industries such as metallurgy, petrochemicals, glass and ceramics, fluorescent materials, and electronic materials. In recent years, the consumption of rare earths has increased significantly, necessitating the recycling of spent rare earth metal slag to reduce resource consumption. One method for recycling rare earth metal slag is the dissolving solution recycling method. In this method, the rare earth waste slag is crushed before dissolution, and then the crushed rare earth metal slag is placed in the dissolving solution for further crushing. The crushed rare earth metal slag is in the form of fragments, and the reaction takes a certain amount of time to dissolve in the solution. The time from crushing the fragmented rare earth metal slag to complete dissolution is relatively long, thus affecting the recycling efficiency of rare earth metal waste slag.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0023] like Figure 1-5As shown in the figure, a recycling device for recovering rare earth metals from rare earth metal slag according to an embodiment of the present invention includes a recycling box 1. A support shaft 3 is installed in the center of the recycling box 1 via a rotating bearing 2. A feeding shaft 4 is fixedly installed on the support shaft 3. A crushing ring 5 is installed on the outer side of the feeding shaft 4 via a clamping block. A crushing groove 6 is formed on the outer side of the crushing ring 5. A bearing bearing 7 is installed above the rotating bearing 2 in the recycling box 1. A bearing rod 8 is rotatably installed between the bearing bearings 7. A crushing shaft 9 is installed on the bearing rod 8. A crushing rod 10 matching the crushing groove 6 is installed on the outer side of the crushing shaft 9. A support shaft 3 is installed on the side of the crushing ring 5 in the recycling box 1. A rotating rod 12 is installed between the bearings of shaft 3. A powder shaft 13 is sleeved on the rotating rod 12. A powder rod 14 matching the crushing trough 6 is sleeved on the outside of the powder shaft 13. An inclined screen plate 15 is installed inside the recovery box 1 below the crushing ring 5. A dissolving box 16 is installed below the inclined screen plate 15. A drive motor 17 is installed on the outside of the recovery chamber at the support shaft 3. The output end of the drive motor 17 is connected to the support shaft 3. A feeding assembly 18 is installed at the top of the recovery box 1. Anti-sticking components 19 are installed on the sides of the feeding shaft 4, the crushing shaft 9, and the powder shaft 13 inside the recovery box 1. A circulation assembly 20 is installed on the outer side of the recovery box 1 near the powder rod 14. In operation, rare earth metal slag is placed in the feeding assembly 18, which transports it to the crushing tank 6. Simultaneously, the drive motor 17 rotates the support shaft 3, causing the rare earth metal slag in the crushing tank 6 to rotate as well. This meshes the crushing tank 6 with the support shaft 3, achieving the effect of crushing the rare earth metal slag. After crushing, the crushing ring 5 continues to rotate with the support shaft 3, while the crushing tank 6 drives the crushing rod 10 to rotate, which in turn drives the bearing rod 8 to rotate on the bearing bearing 7. The crushed rare earth metal slag then continues to rotate with the crushing tank 6 until it reaches the powder rod 14. Through the meshing of the powder rod 14 with the crushing tank 6, the rare earth metal slag undergoes secondary crushing. The process involves crushing the rare earth metal slag, breaking down the metal fragments and impurities within it. The crushed slag falls downwards and passes through an inclined screen 15 into a dissolving tank 16 for dissolution. After dissolution, the next step is performed. During crushing, an anti-sticking component 19 vibrates the crushing shaft 9, feeding shaft 4, and powder shaft 13, preventing the crushed rare earth metal slag and impurities from sticking to them. Unqualified slag is circulated through a circulation component 20 back to the feeding component 18 for further crushing. In this invention, the feeding component 18 transports the rare earth metal slag into the crushing trough, where the crushing rod 10 on the crushing shaft 9 and the powder rod 14 on the powder shaft 13 work together to thoroughly crush the rare earth metal slag.This allows the rare earth metal slag to dissolve fully, thereby accelerating the dissolution efficiency and facilitating the next process. The anti-sticking component 19 prevents raw materials from adhering to the crushing tank 6, crushing rod 10, and powder rod 14, thus avoiding material residue and reducing crushing efficiency.

[0024] In addition, such as Figure 1-5 As shown, in one embodiment, the feeding assembly 18 includes a feeding bin 21. The feeding bin 21 is connected to a conveying channel 22 on the side away from the powder shaft 13. The conveying channel 22 communicates with the side of the recycling box 1. A feeding plate 23 is connected to the recycling box 1 at the conveying channel 22. The feeding plate 23 extends to the side of the crushing ring 5. A feeding port is provided at the top of the feeding bin 21. A sealing door is installed at the feeding port. An inclined plate 24 inclined towards the conveying channel 22 is installed at the bottom of the feeding bin 21. Rare earth metal slag is conveyed into the conveying channel 22 through the inclined plate 24 in the feeding bin. Rare earth metal is conveyed into the crushing tank 6 for crushing through the inclined conveying channel 22.

[0025] In addition, such as Figure 1-5As shown, in one embodiment, the anti-sticking component 19 includes a striking component 25 and a vibration component 26. The striking component 25 includes three striking cavities 27, which are installed inside the recycling bin 1 at the sides of the feeding shaft 4, the rolling shaft 9, and the powder shaft 13. A striking rod 28 is slidably installed inside each striking cavity 27. A reset ring is installed on the side of the striking rod 28 away from the striking cavity. A reset spring 30 is sleeved between the reset ring and the striking cavity. A rolling steel ball 31 is rotatably installed on the side of the striking rod 28 away from the striking cavity. Four arc-shaped inclined blocks 32, corresponding to the rolling steel balls 31, are installed around the center of the side of the feeding shaft 4, the rolling shaft 9, and the powder shaft 13 near the striking rod 28. A striking block 33 is installed on the side of the reset ring away from the feeding shaft 4, the rolling shaft 9, and the powder shaft 13. The vibration component 26... The moving component 26 includes a reset bearing 34, which is installed at both ends of the feeding shaft 4, the rolling shaft 9, and the powder shaft 13. A vibration spring 35 is installed between the reset bearing 34 and the rotating bearing 2, the load bearing 7, and the support shaft 3. The rotation of the feeding shaft 4, the rolling shaft 9, and the powder shaft 13 causes the rolling steel ball 31 to rotate on the arc-shaped inclined block 32, thereby pushing the rolling steel ball 31 and causing the striking rod 28 to move into the striking cavity 27. At this time, the reset ring will move, which in turn will drive the striking block 33 to move. When it reaches the highest point of the arc-shaped inclined block 32, it will fall rapidly, causing the striking block 33 to strike the feeding shaft 4, the rolling shaft 9, and the powder shaft 13. This will drive the feeding shaft 4, the rolling shaft 9, and the powder shaft 13 to move. The vibration spring 35 resets the material, achieving a vibration effect, thereby removing the raw materials stuck to the feeding shaft 4, the rolling shaft 9, and the powder shaft 13, thus increasing the crushing efficiency.

[0026] In addition, such as Figure 1-4 As shown, in one embodiment, the circulation assembly 20 includes a circulation box 36, which is connected to the recovery box 1 at the downward inclined section of the inclined screen. A fan unit 37 is installed inside the circulation box 36, and a circulation channel 38 is installed at the top of the circulation box 36. The circulation channel 38 is connected to the top of the inclined plate 24 in the feeding bin 21. A leak-proof net 39 is installed at the top of the fan unit 37 inside the circulation box 36. A conveying pipe 40 and an output pipe 41 are respectively connected to both ends of the installation box and the dissolving box 16. A filter element is installed inside the output pipe 41. The fan unit 37 conveys unqualified raw materials to the feeding mechanism through the circulation channel 38 to facilitate the next conveying. The conveying pipe 40 and the output pipe 41 facilitate the conveying of the dissolving liquid and the dissolved raw materials in the dissolving box 16, and the filter element filters impurities.

[0027] Based on the above scheme, the working principle or operation process of this invention in actual application is as follows: During use, rare earth metal slag is placed in the feeding assembly 18, which transports the slag to the crushing tank 6. Simultaneously, the drive motor 17 drives the support shaft 3 to rotate, causing the rare earth metal slag in the crushing tank 6 to rotate as well, thus engaging the crushing tank 6 and achieving the effect of crushing the rare earth metal slag. After crushing, the crushing ring 5 continues to rotate with the support shaft 3, and the crushing tank 6 drives the crushing rod 10 to rotate, thereby causing the bearing rod 8 to rotate on the bearing bearing 7. Subsequently... The crushed rare earth metal slag will continue to follow the rotation of the crushing tank 6 until the crushing tank 6 reaches the powder rod 14. Through the meshing of the powder rod 14 and the crushing tank 6, the rare earth metal slag will be crushed a second time, crushing the metal fragments and impurities within the rare earth metal slag. At this time, the crushed metal slag will fall downwards and enter the dissolving tank 16 through the inclined screen plate 15 for dissolution. After dissolution, the next process will proceed. At the same time, during the crushing operation, the anti-sticking component 19 will strike the crushing shaft 9, the feeding shaft 4, and the powder shaft 13 to make them vibrate, preventing the crushed rare earth metal slag and impurities from sticking together. Above, the crushed and substandard material is circulated through the circulation component 20 to the feeding component 18 for further crushing. Rare earth metal slag is conveyed to the conveying channel 22 via the inclined plate 24 inside the feeding chamber. The rare earth metal is then conveyed to the crushing tank 6 for crushing via the inclined conveying channel 22. Furthermore, the rotation of the feeding shaft 4, the crushing shaft 9, and the powder shaft 13 causes the rolling steel ball 31 to rotate on the arc-shaped inclined block 32, thereby pushing the rolling steel ball 31 and causing the striking rod 28 to move into the striking cavity 27. This, in turn, causes the reset ring to move, which in turn moves the striking block 33. Upon reaching the arc-shaped inclined block 37... At its highest point, the material rapidly falls, causing the striking block 33 to strike the feeding shaft 4, the grinding shaft 9, and the powder shaft 13. This causes the feeding shaft 4, the grinding shaft 9, and the powder shaft 13 to move. The vibration spring 35 resets the material, achieving a vibration effect. This causes the raw materials stuck to the feeding shaft 4, the grinding shaft 9, and the powder shaft 13 to fall off, thereby increasing the crushing efficiency. Furthermore, the blower unit 37 transports unqualified raw materials through the circulation channel 38 to the feeding mechanism for easy conveying in the next cycle. The conveying pipe 40 and the output pipe 41 facilitate the conveying of the dissolving liquid and the dissolved raw materials in the dissolving tank 16, and the filter element filters out impurities.

[0028] With the above-described solution of the present invention, the present invention can realize the thorough crushing of rare earth metal slag by conveying it into the crushing tank through the feeding assembly 18, and the crushing rod 10 on the crushing shaft 9 and the powder rod 14 on the powder shaft 13 through cooperation, so that the rare earth metal slag can be fully dissolved, thereby accelerating the dissolution efficiency and facilitating the next process. The anti-sticking assembly 19 prevents raw materials from sticking to the crushing tank 6, the crushing rod 10 and the powder rod 14, resulting in the residue of raw materials and reducing the crushing efficiency.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
