Description

Technical Field

[0001] The invention belongs to the technical field of ore magnetic separation and recovery, and specifically relates to a green production and recovery device for rare earth functional materials. Background Art

[0002] Rare earth functional materials are materials with rare earth elements as the main component, which have specific functions and excellent performance due to their unique electronic structure and physical and chemical properties. They include rare earth permanent magnet materials (such as NdFeB), luminescent materials (such as phosphors), hydrogen storage materials, catalytic materials, glass ceramic materials and high-temperature superconducting materials. These materials are widely used in motors, lighting, display technology, batteries, petrochemicals, automobile exhaust purification and energy transmission, showing extremely high application value and broad market prospects.

[0003] The existing technology separates and screens the magnetic materials in the rare earth materials through a magnetic separator. The specific magnetic separation process is an efficient separation process. First, the rare earth ore that has been preliminarily crushed is fed into the upper hopper of the magnetic separator, and the vibration motor is vibrated to ensure that the ore is evenly distributed after falling onto the conveyor belt. Subsequently, the ore enters the magnetic separation area through the conveyor belt transmission. Since the rare earth elements are magnetic, they will be adsorbed on the surface of the magnetic roller by the strong magnetic field, while the non-magnetic substances will not be adsorbed. They are thrown out of the magnetic separation area by the conveyor belt driven by the magnetic roller and collected by the collection frame. As the magnetic roller drives the conveyor belt to drive, the rare earth minerals magnetically attracted to the surface of the conveyor belt are continuously adsorbed and brought to the demagnetization area, and finally fall into the concentrate collection tank for collection.

[0004] However, in the existing magnetic separator, as the core component of magnetic separation, the magnetic roller generates heat accumulation due to electromagnetic conversion and mechanical friction during continuous high-speed rotation. This temperature rise effect directly causes the magnetic performance of the permanent magnetic material to decline, weakening the effective adsorption force on rare earth minerals. The weakening of magnetism directly affects the magnetic separation effect, making it difficult to separate magnetic materials from non-magnetic materials, causing magnetic rare earth materials to be mistakenly brought into the collection frame of non-magnetic materials, reducing the overall quality of magnetic separation operations and causing the loss of rare earth resources.

[0005] In addition, during the continuous rotation of the magnetic roller, the viscosity of the lubricating grease inside the bearing decreases due to heat, and gradually seeps out and migrates to the surface of the conveyor belt under the action of centrifugal force. These oily substances mix with the mineral powder to form a viscous complex, which contaminates the surface of the ore and hinders the effective adsorption and separation process between the magnetic substance in the ore and the magnetic field of the magnetic roller. This oil adhesion phenomenon not only reduces the efficiency of magnetic separation, but also further aggravates the decline in the quality of magnetic separation.

[0006] To this end, the present invention provides a green production and recovery device for rare earth functional materials. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figures 1 to 9As shown, a green production and recycling device for rare earth functional materials described in an embodiment of the present invention includes a body 1, a fixed motor 12 is fixedly connected to one side of the body 1, a magnetic separation roller 13 is fixedly connected to the output end of the fixed motor 12, the magnetic separation roller 13 is transmission-connected to a conveyor belt 14, the upper surface of the body 1 is fixedly connected to a feed port 11, a collecting frame 15 is provided on one side of the body 1, a fixed frame 16 is clamped on the other side of the body 1, a collecting trough 17 is provided inside the body 1, a baffle 18 is rotatably connected inside the body 1, a cooling component is provided inside the body 1, the cooling component includes a fixed plate 21 fixedly connected to the inside of the body 1, a surface of the fixed plate 21 is provided with a plurality of spray holes 22, and the plurality of spray holes 22 are all facing the magnetic separation roller 13, a pressure box 2 is fixedly connected to one side of the body 1, the fixed plate 21 passes through one side of the body 1 and is fixedly connected to the pressure box 2, water is stored in the pressure box 2, and a pressure tank is built in.

[0035] Specifically, in the existing magnetic separator, during the magnetic separation process, the magnetic roller, as the core component of the magnetic separation, generates heat accumulation due to electromagnetic conversion and mechanical friction during continuous high-speed rotation. This temperature rise effect directly causes the magnetic performance of the permanent magnetic material to decline, weakening the effective adsorption force on rare earth minerals. The weakened magnetism directly affects the magnetic separation effect, making it difficult to separate the magnetic material from the non-magnetic material, causing the magnetic rare earth material to be mistakenly brought into the collection frame 15 of the non-magnetic material, reducing the overall quality of the magnetic separation operation, and causing the problem of rare earth resource loss;

[0036] Therefore, the present invention solves this problem by setting a corresponding structure. First, the crushed rare earth ore is fed through the feed port 11 fixed to the upper surface of the machine body 1. After the feed port 11 is fed, the rare earth ore falls onto the conveyor belt 14. The fixed motor 12 drives the magnetic separation roller 13 to rotate. At the same time, the magnetic separation roller 13 drives the conveyor belt 14 to transmit. The transmission of the conveyor belt 14 drives the rare earth ore to move toward the magnetic separation roller 13. The conveyor belt 14 is set at a certain inclination angle to drop larger pieces of rare earth ore along the conveyor belt 14 into the fixed frame 16 for secondary crushing. The rare earth ore is too large to be effectively magnetically attracted by the magnetic force of the magnetic separation roller 13. After the rare earth ore is transmitted to the magnetic separation roller 13, it is magnetically attracted by the magnetic separation roller 13 and transmitted to the collecting tank 17 below the magnetic separation roller 13. The non-magnetic rare earth ore is thrown into the collecting frame 15 by the conveyor belt 14.

[0037] During the process of the magnetic separation roller 13 rotating for magnetic separation, the built-in pressure tank in the pressure box 2 is started. After the pressure tank is started, the pressure tank will squeeze the water in the pressure box 2 and spray it out from the spray hole 22 on the surface of the fixed plate 21. After the water is sprayed out from the spray hole 22, it will spray toward the magnetic separation roller 13 that is rotating for magnetic separation, and actively cool the magnetic separation roller 13, thereby improving the magnetic separation efficiency of the magnetic separation roller 13, preventing the magnetic separation roller 13 from generating an unstable magnetic field due to high temperature, and improving the quality of magnetic separation;

[0038] The problem that the magnetic properties of the permanent magnetic material of the magnetic separation roller 13 deteriorate due to the temperature rise effect, resulting in reduced magnetic separation quality, is solved.

[0039] like Figure 5 and Figure 6 As shown, a cleaning assembly is provided inside the machine body 1 of this embodiment, and the cleaning assembly includes two first trough bodies 3 opened on both sides of the inner wall of the machine body 1, and reciprocating screws 31 are rotatably connected in the two first trough bodies 3, and the two reciprocating screws 31 are slidably connected to the same sliding plate 32, and a brush plate 33 is fixedly connected to the upper surface of the sliding plate 32, and the brush plate 33 abuts against the conveyor belt 14, and the brush plate 33 can clean the dirt on the surface of the conveyor belt 14.

[0040] Specifically, by driving the two reciprocating screws 31 to rotate in the corresponding first trough body 3, since the sliding plate 32 is slidably connected to the two reciprocating screws 31, the sliding plate 32 will reciprocate along the axial direction of the reciprocating screw 31, and the brush plate 33 on the sliding plate 32 will move therewith, generating continuous friction with the surface of the conveyor belt 14, thereby effectively cleaning the dirt on the conveyor belt 14, realizing automatic cleaning of the surface of the conveyor belt 14, improving the cleaning efficiency, and reducing the labor intensity of manual cleaning. At the same time, due to the direct contact between the brush plate 33 and the conveyor belt 14, the cleaning effect is more thorough, which helps to keep the conveyor belt 14 clean and the equipment operates normally.

[0041] like Fig. 9 As shown, a connecting plate 34 is fixedly connected to the inner wall of the machine body 1 of this embodiment, and a plurality of cleaning strips 35 made of metal are fixedly connected to one side of the connecting plate 34 corresponding to the brush plate 33 . The plurality of cleaning strips 35 are used to clean rare earth ore stones stuck on the brush plate 33 .

[0042] Specifically, when the brush plate 33 is driving the reciprocating screw 31 to clean the conveyor belt 14, if rare earth ore stones are stuck on the brush plate 33, the metal cleaning strip 35 on the connecting plate 34 will move with the brush plate 33 and passively move the stones stuck in the brush plate 33, removing them from the brush plate 33, thereby effectively preventing the brush plate 33 from being jammed by stones and reducing its cleaning quality, thereby ensuring the continuity and efficiency of the cleaning work, while also reducing the potential damage to the equipment caused by stone accumulation and extending the service life of the equipment.

[0043] like Figure 3 and Figure 6 As shown, in this embodiment, a positioning plate 36 is fixedly connected to one side of the sliding plate 32, and a positioning cavity 323 is opened inside the positioning plate 36. A limiting plate 37 is slidably connected to one side of the positioning plate 36, and a limiting cavity 39 is opened inside the limiting plate 37. A storage box 38 is fixedly connected to one side of the limiting plate 37, and the storage box 38 is fixedly connected to the inner wall of the body 1. A pressure pump 315 is fixedly connected to the lower surface of the limiting plate 37.

[0044] Specifically, when the sliding plate 32 moves driven by the reciprocating screw 31, it drives the positioning plate 36 to move together. The positioning cavity 323 in the positioning plate 36 slides with the limit plate 37 to ensure that the limit plate 37 moves stably on a specific path. During the movement of the sliding plate 32, the pressure pump 315 is started to deliver the oil cleaning agent in the storage box 38 to the brush plate 33 through the pipeline in the limit cavity 39 to enhance the cleaning effect, realize the automatic supply of the cleaning agent, improve the intelligence and automation level of the cleaning operation, and ensure the accuracy and timeliness of the use of the cleaning agent.

[0045] like Figure 7 and Figure 8 As shown, in this embodiment, a sealing assembly is provided on one side of the limit plate 37 close to the storage box 38, and the sealing assembly includes a limit groove 310 opened at the end of the limit plate 37, a rotating shaft 311 is fixedly connected in the limit groove 310, a torsion spring 312 is sleeved on the circumferential surface of the rotating shaft 311, and a sealing plate 313 is fixedly connected to the circumferential surface of the torsion spring 312.

[0046] Specifically, when the limit plate 37 is close to the storage box 38, the sealing plate 313 opens to add the oil cleaning agent under the action of pressure, and when the limit plate 37 is away from the storage box 38, it is tightly attached to the opening of the storage box 38 under the action of the torsion spring 312 to form a seal to prevent liquid leakage. As the limit plate 37 moves, the sealing plate 313 flexibly rotates with the cooperation of the rotating shaft 311 and the torsion spring 312 to maintain a close fit with the opening of the storage box 38. The beneficial effect is that the sealing assembly effectively prevents the leakage of liquid during the transmission process, ensures the full utilization of the cleaning agent, and also protects the storage box 38 and the surrounding environment from pollution.

[0047] like Figures 7 to 9 As shown, after the reciprocating screw 31 of this embodiment is driven by the built-in motor of the body 1, the reciprocating screw 31 drives the sliding plate 32 to slide back and forth. The reciprocating motion of the sliding plate 32 drives the positioning plate 36 to move laterally in the limit plate 37, so that the pressure in the limit plate 37 becomes larger, and the pressure squeezes the sealing plate 313 to rotate. At this time, the oil cleaning agent stored in the storage box 38 is pressurized by the pressure pump 315 and flows into the positioning cavity 323 along the limit cavity 39, overflows from the upper surface of the brush plate 33, and the auxiliary brush plate 33 cleans the oil on the surface of the conveyor belt 14.

[0048] Specifically, during the continuous rotation of the magnetic roller, the lubricating grease inside the bearing is heated and its viscosity is reduced. Under the action of centrifugal force, it gradually seeps out and migrates to the surface of the conveyor belt 14. These oily substances are mixed with the mineral powder to form a viscous complex, which pollutes the surface of the ore and hinders the effective adsorption and separation process between the magnetic substance in the ore and the magnetic field of the magnetic roller. This oil adhesion phenomenon not only reduces the efficiency of magnetic separation, but also further aggravates the problem of decreased magnetic separation quality.

[0049] The reciprocating screw 31 is driven to rotate by the built-in motor of the body 1, thereby driving the sliding plate 32 to slide back and forth in the body 1. The movement of the sliding plate 32 causes the positioning plate 36 to slide in the limiting plate 37. During this process, the pressure in the internal space of the limiting plate 37 increases due to the squeezing of the sliding plate 32, pushing the sealing plate 313 to rotate around the rotating shaft 311, opening the connection with the storage box 38, and then, the oil cleaning agent in the storage box 38 is pressurized by the pressure pump 315, flows into the positioning cavity 323 through the limiting cavity 39, and finally overflows from the upper surface of the brush plate 33, and works together with the brush plate 33 to deeply clean the oil on the surface of the conveyor belt 14, thereby realizing the automatic supply and uniform distribution of the oil cleaning agent, and improving the efficiency and effect of cleaning the oil on the surface of the conveyor belt 14. At the same time, the driving mode of the reciprocating screw 31 ensures the continuity and stability of the cleaning operation.

[0050] like Figure 7 As shown, in this embodiment, a cone plate 314 is fixedly connected to the upper surface of the limiting plate 37 , and the cone plate 314 is used to prevent rare earth ore from piling up on the upper surface of the limiting plate 37 .

[0051] Specifically, the upper surface of the cone plate 314 is inclined in a conical shape, and the rare earth ore slides along the cone plate 314 under the action of gravity and is difficult to accumulate, which effectively prevents the rare earth ore from accumulating on the upper surface of the limit plate 37, ensures the smooth movement of the limit plate 37 and the normal supply of the cleaning agent, and improves the stability of the equipment operation and the cleaning efficiency.

[0052] Embodiment 2: Figures 1 to 9 As shown, compared with Example 1, another embodiment of the present invention is: a push-off assembly is provided on one side of the limiting plate 37, and the push-off assembly is used to clean the rare earth ore accumulated on the upper surface of the positioning plate 36. The push-off assembly includes two auxiliary blocks 316 fixedly connected to the end of the limiting plate 37, and one side of the auxiliary block 316 is fixedly connected to a fixed tube 317, and a spring 318 is fixedly connected in the fixed tube 317. One end of the spring 318 is fixedly connected to a plug rod 319, and one end of the plug rod 319 is fixedly connected to a scraper 320. A moving groove 321 is provided between the two scrapers 320, and a cone block 322 is fixedly connected to the upper surface of the positioning plate 36. When the positioning plate 36 slides along the limiting cavity 39, the cone block 322 squeezes the scraper 320 to both sides along the moving groove 321, and the scraper 320 squeezes the spring 318 to retract into the fixed tube 317, thereby clearing the rare earth ore on the upper surface of the positioning plate 36.

[0053] Specifically, when the positioning plate 36 slides along the limiting cavity 39 in the limiting plate 37, the cone block 322 fixed on its upper surface will first encounter the push-open component, and the cone block 322 moves to both sides along the moving groove 321, gradually approaching and squeezing the two scrapers 320, and the scrapers 320 are connected to the spring 318 through the plug rod 319. The elastic effect of the spring 318 enables the scrapers 320 to retract into the fixed tube 317 when being squeezed by the cone block 322. At the same time, the compression of the spring 318 also stores energy. As the cone block 322 continues to move, it pushes the scrapers 320 outward to perform scraping work, scraping off the rare earth ore accumulated on the upper surface of the positioning plate 36. At the same time, the cone block During the movement of 322, it will also assist in pushing away the rare earth ore that has fallen onto the positioning plate 36. When the cone block 322 is reset, the spring 318 returns to its initial state, and the scraper 320 is also reset accordingly, waiting for the next cleaning action. The pushing component utilizes the sliding power of the positioning plate 36, and also realizes the automatic reset of the scraper 320 through the elastic action of the spring 318. No additional driving device is required, and the rare earth ore accumulated on the surface of the positioning plate 36 is effectively cleaned, preventing the accumulation of ore from interfering with the operation of the equipment, ensuring the smooth progress of the cleaning operation. At the same time, the pushing component has a simple structure and is easy to maintain, which reduces the operating cost of the equipment.

[0054] Working principle: first, the crushed rare earth ore is fed through the feed port 11 fixed on the upper surface of the machine body 1. After the feed port 11 is fed, the rare earth ore falls onto the conveyor belt 14, and the fixed motor 12 drives the magnetic separation roller 13 to rotate. At the same time, the magnetic separation roller 13 drives the conveyor belt 14 to transmit. The transmission of the conveyor belt 14 drives the rare earth ore to move toward the magnetic separation roller 13. The conveyor belt 14 is set at a certain inclination angle to drop larger pieces of rare earth ore along the conveyor belt 14 into the fixed frame 16 for secondary crushing. If the rare earth ore is too large, the magnetic force of the magnetic separation roller 13 cannot effectively attract it. After the rare earth ore is transferred to the magnetic separation roller 13, it is magnetically attracted by the magnetic separation roller 13 and transferred to the collecting tank 17 below the magnetic separation roller 13. The non-magnetic rare earth ore is thrown into the collecting frame 15 by the conveyor belt 14.

[0055] During the process of the magnetic separation roller 13 rotating for magnetic separation, the built-in pressure tank in the pressure box 2 is started. After the pressure tank is started, the pressure tank will squeeze the water in the pressure box 2 and spray it out from the spray hole 22 on the surface of the fixed plate 21. After the water is sprayed out from the spray hole 22, it will spray toward the magnetic separation roller 13 that is rotating for magnetic separation, and actively cool the magnetic separation roller 13, thereby improving the magnetic separation efficiency of the magnetic separation roller 13, preventing the magnetic separation roller 13 from generating an unstable magnetic field due to high temperature, and improving the quality of magnetic separation;

[0056] At the same time, by driving the two reciprocating screws 31 to rotate in the corresponding first trough body 3, since the sliding plate 32 is slidably connected to the two reciprocating screws 31, the sliding plate 32 will reciprocate along the axial direction of the reciprocating screw 31, and the brush plate 33 on the sliding plate 32 will move therewith, and generate continuous friction with the surface of the conveyor belt 14, so as to effectively clean the dirt on the conveyor belt 14, realize the automatic cleaning of the surface of the conveyor belt 14, improve the cleaning efficiency, and reduce the labor intensity of manual cleaning. At the same time, due to the direct contact between the brush plate 33 and the conveyor belt 14, the cleaning effect is more thorough, which helps to keep the conveyor belt 14 clean and the normal operation of the equipment;

[0057] When the brush plate 33 is driven by the reciprocating screw 31 to clean the conveyor belt 14, if rare earth ore stones are stuck on the brush plate 33, the metal cleaning strip 35 on the connecting plate 34 will move with the brush plate 33 and passively remove the stones stuck in the brush plate 33 from the brush plate 33, effectively preventing the brush plate 33 from being blocked by stones and reducing its cleaning quality, ensuring the continuity and efficiency of the cleaning work, and also reducing the potential damage to the equipment caused by stone accumulation, thereby extending the service life of the equipment;

[0058] In addition, the reciprocating screw 31 is driven to rotate by the built-in motor of the body 1, thereby driving the sliding plate 32 to slide back and forth in the body 1. The movement of the sliding plate 32 causes the positioning plate 36 to slide in the limiting plate 37. During this process, the pressure in the internal space of the limiting plate 37 increases due to the squeezing of the sliding plate 32, pushing the sealing plate 313 to rotate around the rotating shaft 311, opening the communication port with the storage box 38, and then, the oil cleaning agent in the storage box 38 is pressurized under the action of the pressure pump 315, flows into the positioning cavity 323 through the limiting cavity 39, and finally overflows from the upper surface of the brush plate 33, and works together with the brush plate 33 to deeply clean the oil on the surface of the conveyor belt 14, thereby realizing the automatic supply and uniform distribution of the oil cleaning agent, and improving the efficiency and effect of cleaning the oil on the surface of the conveyor belt 14. At the same time, the driving mode of the reciprocating screw 31 ensures the continuity and stability of the cleaning operation;

[0059] When the positioning plate 36 slides along the limiting cavity 39 in the limiting plate 37, the cone block 322 fixed on its upper surface will first encounter the push-open component, and the cone block 322 moves to both sides along the moving groove 321, gradually approaching and squeezing the two scrapers 320, and the scrapers 320 are connected to the spring 318 through the plug rod 319. The elastic effect of the spring 318 enables the scrapers 320 to retract into the fixed tube 317 when being squeezed by the cone block 322. At the same time, the compression of the spring 318 also stores energy. As the cone block 322 continues to move, the scrapers 320 are pushed outward to perform scraping work, and the rare earth ore accumulated on the upper surface of the positioning plate 36 is scraped off. At the same time, the cone block 3 During the movement of 22, it will also assist in pushing away the rare earth ore that has fallen onto the positioning plate 36. When the cone block 322 is reset, the spring 318 returns to its initial state, and the scraper 320 is also reset accordingly, waiting for the next cleaning action. The pushing component utilizes the sliding power of the positioning plate 36, and also realizes the automatic reset of the scraper 320 through the elastic action of the spring 318. No additional driving device is required, and the rare earth ore accumulated on the surface of the positioning plate 36 is effectively cleaned, preventing the accumulation of ore from interfering with the operation of the equipment, ensuring the smooth progress of the cleaning operation. At the same time, the pushing component has a simple structure, is easy to maintain, and reduces the operating cost of the equipment.
