Description

Technical Field

[0001] The invention relates to the technical field of functional material recovery, in particular to a rare earth functional material gravel waste recovery and screening device. Background Art

[0002] Rare earth functional materials refer to a class of materials that use rare earth elements as the main or key components and have specific functions and excellent performance due to the unique electronic structure and physical and chemical properties of rare earth elements. Rare earth functional materials include: rare earth permanent magnet materials, such as neodymium iron boron permanent magnet materials, which have extremely high magnetic energy product and coercive force and are widely used in motors, electronic equipment, wind power generation and other fields; rare earth luminescent materials, such as rare earth phosphors, are used in lighting, display technology (such as color TVs, LED lights), etc.; rare earth hydrogen storage materials, which can efficiently store and release hydrogen, are used in nickel-hydrogen batteries and hydrogen energy related fields; rare earth catalytic materials, which play an important catalytic role in petrochemicals, automobile exhaust purification and other processes; rare earth glass and ceramic materials, which can improve the performance of glass and ceramics, such as improving hardness and corrosion resistance. Rare earth high-temperature superconducting materials: have zero resistance and complete anti-magnetism at low temperatures, and are used in energy transmission, magnetic levitation and other fields.

[0003] Because rare earth resources are scarce and precious, global rare earth reserves are limited, and gravel-like waste contains considerable rare earth components, the rare earth content in it may still have recycling value. If it is not recycled, it will cause a waste of rare earth resources. It is usually necessary to recycle and screen waste to improve the utilization rate of rare earth resources, reduce dependence on newly mined resources, and ensure the sustainable supply of rare earth resources.

[0004] The existing waste recovery and screening devices for rare earth functional materials, when recycling gravel-like waste, are prone to recovering materials with uneven particle sizes, as some gravel-like waste may have wrapped or adhered structures, which may bring difficulties to subsequent processing and application. In addition, the existing screen mesh apertures are relatively fine, and the processing speed is slow for a large amount of gravel-like waste. At the same time, the material is easily stuck in the holes, and larger particles may be wrapped with rare earth components and cannot be fully exposed, resulting in some rare earths being unable to be effectively recovered, causing waste of resources.

[0019] 3. In the rare earth functional material gravel waste recovery and screening device, the sliding component reciprocates up and down to drive the wind component to perform alternating forward and reverse movements. The forward rotation of the wind component helps the material to move in a specific direction, promotes the transmission of the material in the device, and improves the recovery efficiency. The forward airflow generated can more effectively blow light impurities or fine particles away from the heavier rare earth materials, thereby improving the accuracy of screening and separation. The reverse rotation of the wind component generates backward suction, which loosens the material that may be blocked in certain parts and keeps the material flow smooth.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0037] See also Figure 1-Figure 10As shown, the purpose of this embodiment is to provide a rare earth functional material gravel waste recycling and screening device, including a recycling box 1, two baffles 11 are movably connected to the top of the recycling box 1, a crushing assembly 12 is movably connected near the center of the recycling box 1, a sliding assembly 13 is movably connected near the bottom of the recycling box 1, and a screening assembly 14 is movably connected inside the sliding assembly 13, and the screening assembly 14 is located directly below the crushing assembly 12;

[0038] The sliding component 13 passes through the outer wall of the recycling box 1 and is fixedly connected to a wind component 15. The wind component 15 is movably connected to the inside of the bevel near the top of the recycling box 1. The wind component 15 is located above the crushing component 12.

[0039] The screening component 14 is used to drive the material to roll during the screening process and to turn the material over. The up and down movement of the sliding component 13 and the rotation of the screening component 14 generate vibrations to shake off the material stuck in the holes of the screening component 14 and to scrape off the material stuck on the inner wall of the recycling box 1. In addition, the wind component 15 can be driven to perform alternating forward and reverse movements.

[0040] In summary, the improvements of this embodiment are:

[0041] The gravel-like rare earth power waste is poured into the recycling box 1, and the waste passes through the crushing assembly 12, and the gravel-like waste is crushed into fine particles, and then falls on the top of the screening assembly 14, and the waste of qualified size is filtered out through the multiple meshes inside the screening assembly 14;

[0042] The screen assembly 14 rotates to drive the waste to turn over, so as to avoid the material being blocked in the screen mesh. The sliding assembly 13 moves up and down and rotates to produce a slight shake, so that the material blocked inside the screen mesh 14 is vibrated out, and the inner wall of the recycling box 1 is scraped to scrape out the material blocked at the four corners of the recycling box 1. The sliding assembly 13 moves upward, and the material on the top of the screening assembly 14 is driven to approach the outer wall of the crushing assembly 12, so that the incompletely crushed material is crushed for the second time, thereby improving the quality of waste recycling.

[0043] The up and down reciprocating motion of the sliding component 13 drives the wind component 15 to perform alternating forward and reverse motions. The forward rotation of the wind component 15 helps the material to move in a specific direction, promotes the transmission of the material in the device, and improves the recovery efficiency. The forward airflow generated can more effectively blow light impurities or fine particles away from the heavier rare earth materials, thereby improving the accuracy of screening and separation. The reverse rotation of the wind component 15 generates backward suction, which loosens the material that may be blocked in certain parts and keeps the material flow smooth.

[0044] First, the specific structure of the crushing component 12 is disclosed. The crushing component 12 includes two rollers 120, which are movably connected to the inside of the recycling box 1. The two rollers 120 are toothedly connected to each other. A plurality of blades 121 are fixedly connected to the inner wall of the recycling box 1 near the rollers 120. The plurality of blades 121 are connected to the outer wall of the rollers 120 with staggered teeth. The end of the roller 120 passing through the recycling box 1 is fixedly connected to a toothed disk 122. The two toothed disks 122 are toothedly connected. One of the rollers 120 is driven to rotate inside the recycling box 1 by the output shaft of the motor, thereby driving the toothed disk 122 at the end of the roller 120 to rotate. The teeth of the two toothed disks 122 cooperate with each other to rotate, so that the two rollers 120 rotate at the same time, and rotate with the plurality of blades 121 with each other, so that the waste is crushed between the plurality of blades 121 and the outer wall of the roller 120, reducing the particle size of the waste, increasing the specific surface area of ​​the material, making it easier to expose and separate the rare earth components therein, thereby improving the efficiency of the subsequent recycling process.

[0045] Secondly, the specific structure of the sliding assembly 13 is disclosed. The sliding assembly 13 includes a screen frame 130, which is movably connected to the inner wall of the recycling box 1, and the screening assembly 14 is movably connected inside the screen frame 130. Both ends of the screen frame 130 are fixedly connected with slide plates 131, which are movably connected to the inside of the chute of the recycling box 1, and the end of the slide plate 131 passing through the recycling box 1 is fixedly connected with a slider 132, and the inside of the slider 132 is movably connected with a screw 133, and the outer wall of one side of the slider 132 is fixedly connected with a wind assembly 15, and the screw 133 is driven to rotate by the motor output shaft, so that the slider 132 moves up and down between the outer walls of the screw 133, and the slider 132 drives the slider 131 to move up and down inside the chute of the recycling box 1, wherein the inner wall of the chute of the recycling box 1 is provided with a rubber strip, which facilitates the slider 131 to move between the rubber strips while sealing the recycling box 1, and the screen frame 130 is driven up and down by the slider 131 to scrape off the waste stuck in the dead corner of the inner wall of the recycling box 1, thereby improving the screening performance.

[0046] The specific structure of the screening assembly 14 is disclosed again. The screening assembly 14 includes a plurality of short rods 140 and a plurality of long rods 141. The plurality of short rods 140 are longitudinally movably connected to the inside of the screen frame 130, and the plurality of long rods 141 are transversely movably connected to the inside of the screen frame 130. The plurality of short rods 140 are located above the long rods 141. The ends of the short rods 140 and the long rods 141 are fixedly connected with a belt pulley 142, and a belt 143 is movably connected between two adjacent belt pulleys 142. Two micro motors are used to drive one of the short rods 140 and the long rod 141 to rotate respectively, and one of the short rods 140 or the long rod 141 is rotated to drive the belt pulley 142 at its end to rotate, and the belt pulley 143 is driven to rotate by the belt pulley 142, thereby driving the adjacent short rods 140 or the long rod 141 to rotate, wherein the connection of the belt 143 is as shown in FIG. Figure 7As shown, the belts 143 at the ends of the same short rod 140 or long rod 141 are staggered and connected in different directions on the left and right sides, so as to drive the short rods 140 or long rods 141 at the left and right ends to rotate simultaneously;

[0047] By rotating a plurality of short rods 140 and a long rod 141 simultaneously, the unscreened waste is subjected to rolling and turning processing, so that the waste at the bottom is turned over and moved upward, so that the fine waste at the top is turned down and screened out from the holes between the short rods 140 and the long rods 141. When the waste is turned over, when the screen frame 130 moves upward, the unscreened waste is turned upward, so that the waste is close to the crushing assembly 12 for secondary crushing, thereby improving the utilization rate of waste recycling and screening, reducing the waste of resources, and improving the recovery value of rare earth waste. When the screen frame 130 moves downward, the rotation of the short rods 140 and the long rods 141 produces a slight shake, which forms a downward gravity with the inertia of the downward movement of the screen frame 130, thereby improving the waste screening speed and vibrating the waste blocked in the mesh of the short rods 140 and the long rods 141 downward.

[0048] The short rod 140 and the long rod 141 are both made of high-hardness and wear-resistant materials. The short rod 140 and the long rod 141 are made of high-strength, high-hardness and wear-resistant materials such as high manganese steel, alloy steel, and wear-resistant cast iron, and are plated with a wear-resistant metal layer such as chromium, nickel, etc. by electroplating or chemical plating to improve the wear resistance and impact resistance of the short rod 140 and the long rod 141, reduce the damage to the short rod 140 and the long rod 141 caused by gravel-like waste, and increase the service life.

[0049] Finally, the specific structure of the wind assembly 15 is disclosed. The wind assembly 15 includes a rack 150, which is fixedly connected to the outer wall of the slider 132. The tooth surface of the rack 150 is movably connected to a small gear 151. The end of the small gear 151 is fixedly connected to a rotating rod 152, and the end of the rotating rod 152 is fixedly connected to a large gear 153. The three large gears 153 are connected by tooth patterns, one of which is fixedly connected to a support rod 154 at one end, and the support rod 154 is movably connected to the inside of the recycling box 1. The end of the other large gear 153 is fixedly connected to a rotating shaft 155, and the rotating shaft 155 is movably connected to the inside of the recycling box 1. The end of the rotating shaft 155 passes through the inner wall of the recycling box 1 and is fixed. A fan 156 is connected, and the rack 150 is driven to move up and down by the slider 132 moving up and down. The rack 150 moves up and down and rubs against the outer wall of the pinion 151, driving the pinion 151 to perform alternating forward and reverse rotations. The rotation of the pinion 151 drives the rotating rod 152 to rotate, and the rotating rod 152 drives the large gear 153 to rotate. The three large gears 153 rotate in coordination with each other, and the support rod 154 supports the rotation position of one of the large gears 153. The rotation of the large gear 153 drives the rotating shaft 155 to rotate, and the rotating shaft 155 drives the fan 156 to rotate inside the recycling box 1, forming forward and reverse wind forces;

[0050] When the fan 156 rotates forward, it helps the material to move in a specific direction, promotes the transmission of the material within the device, and improves the recovery efficiency. The forward airflow generated can more forcefully blow light impurities or fine particles away from the heavier rare earth materials, thereby improving the accuracy of screening and separation. When the fan 156 rotates reversely, it generates backward suction, which loosens the material that may be blocked in certain parts and keeps the material flow smooth.

[0051] In order to conveniently block the dust generated during the unloading process and prevent the waste from splashing outward during the crushing process, a support rod 111 is fixedly connected inside the baffle 11, and the support rod 111 passes through the outer walls at both ends of the baffle 11 and is movably connected to a support plate 110, and the support plate 110 is fixedly connected to the top of the recycling box 1, and the support rod 111 passes through the outer walls at both ends of the baffle 11 and is movably connected to a rotary spring 112, and the rotary spring 112 is fixedly connected between the baffle 11 and the inside of the support plate 110, through the crushed stone The weight of the waste material presses the baffle 11, thereby driving the rotary spring 112 to twist, and at the same time, the support rod 111 rotates inside the support plate 110, thereby inputting the waste into the recycling box 1. When the waste is unloaded, the baffle 11 loses the pressure of gravity, so that the rotary spring 112 rebounds by its own elastic force, driving the baffle 11 to bounce upward, and the support rod 111 rotates on the support plate 110, so that the two baffles 11 seal the recycling box 1, block dust, and prevent waste from splashing.

[0052] In summary, the working principle of this solution is as follows:

[0053] The gravel-like waste material is pressed against the baffle plate 11 by its own gravity, thereby driving the rotary spring 112 to twist, and at the same time, the support rod 111 rotates inside the support plate 110, thereby inputting the waste material into the recycling box 1. When the waste material is unloaded, the baffle plate 11 loses the gravity pressure, thereby causing the rotary spring 112 to rebound by its own elastic force, driving the baffle plate 11 to bounce upward, and the support rod 111 rotates on the support plate 110, so that the two baffle plates 11 seal the recycling box 1, block dust, and prevent waste material from splashing. The motor output shaft drives one of the rollers 120 to rotate inside the recycling box 1, thereby The toothed disc 122 at the end of the roller 120 is driven to rotate, and the teeth of the two toothed discs 122 cooperate with each other to rotate, so that the two rollers 120 rotate simultaneously, and the multiple blades 121 rotate with each other, so that the waste is crushed between the multiple blades 121 and the outer wall of the roller 120, reducing the particle size of the waste, increasing the specific surface area of ​​the material, making it easier to expose and separate the rare earth components therein, thereby improving the efficiency of the subsequent recycling process, and crushing the gravel-like waste into fine particles, which fall on the top of the screening component 14, and the waste of qualified size is filtered out through the multiple meshes inside the screening component 14;

[0054] The output shaft of the motor drives the screw 133 to rotate, so that the slider 132 moves up and down between the outer walls of the screw 133, and the slider 132 drives the slide plate 131 to move up and down inside the chute of the recycling box 1, wherein the inner wall of the chute of the recycling box 1 is provided with a rubber strip, which facilitates the slide plate 131 to move between the rubber strips while sealing the recycling box 1, and drives the screen frame 130 to move up and down through the slide plate 131, so as to scrape off the waste stuck in the dead corner of the inner wall of the recycling box 1, thereby improving the screening performance;

[0055] Two micro motors are used to drive one of the short rods 140 and the long rod 141 to rotate respectively, and one of the short rods 140 or the long rod 141 is rotated to drive the belt pulley 142 at its end to rotate, and the belt pulley 142 drives the belt 143 to rotate, thereby driving the adjacent short rod 140 or the long rod 141 to rotate; by rotating multiple short rods 140 and long rods 141 at the same time, the unscreened waste is rolled over, so that the waste at the bottom is turned over and moved upward, so that the small waste at the top is turned down and screened out from the hole between the short rod 140 and the long rod 141;

[0056] While the waste is being turned over, when the screen frame 130 moves upward, the waste that has not been screened out is turned upward, so that the waste is close to the crushing assembly 12 for secondary crushing, thereby improving the utilization rate of waste recovery screening, reducing the waste of resources, and improving the recovery value of rare earth waste. When the screen frame 130 moves downward, the rotation of the short rod 140 and the long rod 141 produces a slight shake, which forms a downward gravity with the inertia of the downward movement of the screen frame 130, thereby improving the waste screening speed and vibrating the waste blocked in the mesh of the short rod 140 and the long rod 141 downward.

[0057] The rack 150 is driven to move up and down by the slider 132, and the rack 150 moves up and down and rubs against the outer wall of the pinion 151 by the up and down movement, so as to drive the pinion 151 to perform alternating forward and reverse rotations. The rotation of the pinion 151 drives the rotating rod 152 to rotate, and the rotating rod 152 drives the large gear 153 to rotate. The three large gears 153 rotate in coordination with each other, and the rotation position of one of the large gears 153 is supported by the support rod 154. The rotation of the large gear 153 drives the rotating shaft 155 to rotate, and the rotating shaft 155 drives the fan 156 to rotate inside the recycling box 1, so as to form forward and reverse wind forces. When the fan 156 rotates forward, it helps the material to move along a specific direction, promotes the transmission of the material in the device, and improves the recycling efficiency. The forward airflow generated can more effectively blow light impurities or fine particles away from the heavier rare earth materials, so as to improve the accuracy of screening and separation. When the fan 156 rotates reversely, a backward suction force is generated to loosen the material that may be blocked in certain parts, so as to keep the material flow smooth.
