Description

Technical Field

[0001] The present invention relates to the technical field of copper powder extraction, and specifically to a process and device for efficiently extracting copper powder from waste lithium batteries. Background Art

[0002] The recycling of waste lithium batteries is a key link in resource recycling and carbon neutralization. The residual copper component is an important part of lithium batteries. By extracting the copper component, energy consumption can be effectively reduced, and at the same time, the economy of the entire copper material can be improved.

[0003] During the recycling process of waste lithium batteries, copper and aluminum are the two main metal components, coming from copper foil and aluminum foil respectively. Due to their different physical and chemical properties, air separation technology can be used for efficient screening.

[0004] During the entire screening process, copper powder and aluminum powder will all fall on the conveying plate. When screening before being conveyed to the air separator, the piled-up materials will fall together. When the air separator blows the copper powder and aluminum powder with wind, a large amount of copper powder and aluminum powder will fall simultaneously, making the wind of the air separator unable to completely penetrate the barrier formed by the copper powder and aluminum powder, resulting in some aluminum powder falling with the copper powder and being unable to be blown by the air separator, deteriorating the overall screening effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a process and device for efficiently extracting copper powder from waste lithium batteries to solve the problems mentioned in the above process.

[0007] S1, the material is introduced into the interior of the feed bin through the feed port of the feed bin and falls on the vibrating sieve plate in the vibration assembly;

[0008] S2, after the drive motor in the drive assembly is started, the drive motor drives the support plug rod to move left and right reciprocally through the reciprocating groove on the reciprocating groove rod, so that the blanking plate moves left and right reciprocally, thereby driving the vibration assembly to vibrate up and down reciprocally;

[0009] S3, through the vibration of the vibrating sieve plate on the vibration assembly, the material falling on it is shaken loose, and at the same time, the driving leveling plate is driven to evenly level the piled-up material, improving the screening rate;

[0010] S4, through the dispersion and screening of the vibrating sieve plate, the material evenly falls onto the bearing plate, and then under the conveyance of the bearing plate, the material is sent in front of the air separation fan to screen out the copper powder in the material.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1.

Under this vibration, the materials falling on the vibrating sieve plate are shaken loose.

[0025] 2. At the same time, when the materials falling on the vibrating sieve plate are leveled on the vibrating sieve plate by the provided leveling plate, the leveled materials will be evenly laid when falling on the lower bearing plate, avoiding the piled-up materials gathering together and being screened by the air separator together. By evenly leveling the materials, the screening rate of the materials can be increased. At the same time, when the materials fall on the bearing plate for conveying, they can be fully screened by the air separator when reaching the air separator, avoiding blockage between the materials;

[0026] 3. At the same time, the moving directions between the provided blanking plate and the bearing plate are not the same, so that some materials falling on the blanking plate can be conveyed to the central bearing plate by the reciprocating movement of the blanking plate. These materials are conveyed to the air separation location of the air separator through the conveying of the bearing plate to complete the entire screening process, improving the overall utilization rate of the materials and screening out the copper powder in the materials.

Detailed implementation mode

[0045] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by showing examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but covers any modification, replacement, and improvement of elements, components, and algorithms without departing from the spirit of the present invention. Well-known structures and technologies are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the present invention.

[0046] Embodiment 1

[0047] Referring to Figure 1-16 , for the first embodiment of the present invention, there is provided: a process for efficiently extracting copper powder from waste lithium batteries, including the following steps,

[0048] S1, the material is introduced into the interior of the feed bin 2 through the feed port of the feed bin 2 and lands on the vibrating sieve plate 54 in the vibration assembly 5;

[0049] S2, after the drive motor 31 in the drive assembly 3 is started, the drive motor 31 drives the support insertion rod 35 to move left and right reciprocally through the reciprocating groove on the reciprocating groove rotating rod 33, so that the blanking plate 36 moves left and right reciprocally, thereby driving the vibration assembly 5 to vibrate up and down reciprocally;

[0050] S3. Through the oscillation of the vibrating sieve plate 54 on the oscillation component 5, the materials falling thereon are shaken and dispersed. At the same time, the driving leveling plate 61 is driven to evenly level the piled-up materials, thereby improving the screening rate.

[0051] S4. Through the dispersion and screening of the vibrating sieve plate 54, the materials evenly fall onto the bearing plate 43. Subsequently, under the conveyance of the bearing plate 43, the materials are sent in front of the air separation fan 7, and the copper powder in the materials is screened out.

[0052] Embodiment 2

[0053] Referring to Figure 1-12 , which is the second embodiment of the present invention, provides a device for efficiently extracting copper powder from waste lithium batteries, including a base 1. A feed bin 2 is arranged on the base 1. The feed bin 2 is composed of a square bin body and a feed inlet. A ventilation opening is formed through one side of its square bin body to provide an air inlet channel, facilitating the subsequent provision of a sufficient external air circulation channel during air separation screening. A driving component 3 is arranged on the feed bin 2. The driving component 3 is used to drive the blanking plate 36 to move reciprocally, so that the copper-aluminum powder falling on the edge of the blanking plate 36 can converge towards the center. A placing seat 4 is arranged inside the feed bin 2. One end of the placing seat 4 is fixedly connected to the inner wall of the feed bin 2. Under the action of the placing seat 4, the entire oscillation component 5 is supported to vibrate reciprocally, so that the materials falling on the oscillation component 5 can be dispersed and fall on the bearing plate. An oscillation component 5 is movably arranged on the placing seat 4;

[0054] The oscillation component 5 includes a U-shaped plate 51 arranged on one side of the placing seat 4. Sliding grooves 511 and lifting grooves 512 are symmetrically formed on the U-shaped plate 51. A clamping and sliding connection is formed between the sliding groove 511 and the convex block slide plate 52. Under the movement of the convex block slide plate 52, the cooperation plate 53 is pushed to lift and lower. Under the lifting and lowering of the cooperation plate 53, the vibrating sieve plate 54 oscillates reciprocally. Under the oscillation of the vibrating sieve plate 54, the materials are shaken and dispersed. At the same time, under this oscillation, the copper powder and aluminum powder are shaken and dispersed. A clamping and sliding connection is formed between the provided lifting groove 512 and the provided inclined push plate 55. The inclined push plate 55 is driven to reciprocally lift and lower under the movement of the blanking plate 36, so that the inclined push plate 55 presses the convex block slide plate 52 to slide on the U-shaped plate 51;

[0055] The bump slide plate 52 is symmetrically and movably arranged on the U-shaped plate 51, and the bump slide plate 52 is composed of a spherical block 521 and a long bump 522. A push rod is arranged on the side of the bump slide plate 52 close to the inclined push plate 55, and the push rod contacts the inclined surface of the inclined push plate 55. When the inclined push plate 55 descends, it will squeeze the push rod to drive the bump slide plate 52 to displace. At the same time, the maximum length of the long bump 522 on the entire bump slide plate 52 is less than the overall diameter of the spherical block 521, so that when the bump slide plate 52 squeezes the mating plate 53, the contact is always made by the spherical block 521. The contact between the long bump 522 and the mating plate 53 is to keep the mating plate 53 at a certain height after being lifted. When the entire bump slide plate 52 completely enters the through curved hole provided on the mating plate 53, the mating plate 53 will instantaneously fall without external force, thus forming a certain vibration. And through the cooperation between the spherical block 521 on the bump slide plate 52 and the array of through curved holes on the mating plate 53, when the bump slide plate 52 moves, it pushes the mating plate 53 to reciprocate up and down, realizing the reciprocating oscillation of the entire vibrating sieve plate 54;

[0056] The mating plate 53 is movably arranged on the side of the bump slide plate 52 away from the U-shaped plate 51, and through curved holes are arrayed on the mating plate 53. The through curved holes provided on the mating plate 53 are used to cooperate with the bump slide plate 52. When the bump slide plate 52 moves, the spherical block 521 provided thereon continuously moves out of the through hole and contacts and squeezes one side of the entire mating plate 53. After the mating plate 53 rises and the entire bump slide plate 52 is located at the exact center of the opening on the mating plate 53, the entire mating plate 53 instantaneously falls without the action of external force lifting, forming an oscillating effect, and the materials falling on the vibrating sieve plate 54 arranged on one side of the mating plate 53 are shaken loose. The vibrating sieve plate 54 is arranged on one side of the mating plate 53, and the vibrating sieve plate 54 is directly below the feed inlet on the feed bin 2. Rubber pads are arranged on both sides of the vibrating sieve plate 54. By the movement of the blanking plate 36 contacting the rubber pads, the vibrating sieve plate 54 is subjected to a certain impact. Under this impact, combined with the up and down oscillation of the vibrating sieve plate 54 itself, the materials falling on the vibrating sieve plate 54 are dispersed. The overall contour of the vibrating sieve plate 54 is larger than the opening contour of the feed inlet on the feed bin 2, so that the materials falling from the feed inlet can be completely received by the vibrating sieve plate 54 and thus shaken loose. Several sieve holes are arrayed on the vibrating sieve plate 54. Through the oscillation of the entire vibrating sieve plate 54, the materials falling on it are shaken loose, and the agglomerates formed by the electrostatic phenomenon of copper powder and aluminum powder in the materials are broken up to avoid affecting the subsequent screening;

[0057] On one side of the U-shaped plate 51 close to the vibrating sieve plate 54, inclined push plates 55 are symmetrically arranged, and the inclined push plates 55 are engaged and slidable with the U-shaped plate 51. The inclined push plates 55 form an engaged and sliding relationship with the blanking plate 36 on the driving assembly 3 through the engaging rods 551 arranged on one side thereof. When the blanking plate 36 moves reciprocally, the arranged inclined push plates 55 will perform reciprocating lifting and lowering. Under the lifting and lowering of the inclined push plates 55, the inclined surfaces of the inclined push plates 55 will squeeze the ejector rods arranged on the convex block slide plate 52, causing the convex block slide plate 52 to displace. On the side of the vibrating sieve plate 54 away from the base 1, a flattening assembly 6 is movably arranged;

[0058] Through the reciprocating lifting and lowering of the inclined push plates 55, the arranged convex block slide plate 52 is moved. Under the action of the convex block slide plate 52 and the openings arranged on the mating plate 53, the mating plate 53 is continuously lifted, causing the vibrating sieve plate 54 arranged on one side of the mating plate 53 to vibrate, so that the materials falling on it are shaken loose, reducing the agglomeration phenomenon among the materials.

[0059] Inside the feed bin 2, a telescopic plate 21 is arranged, and the side of the telescopic plate 21 away from the feed bin 2 is in contact with the vibrating sieve plate 54. On the side of the U-shaped plate 51 close to the mating plate 53, sliding grooves 511 are arranged in an array, and the sliding grooves 511 are engaged and slidable with the convex block slide plate 52. On the side of the U-shaped plate 51 close to the inclined push plates 55, lifting grooves 512 are symmetrically arranged, and the lifting grooves 512 are engaged and slidable with the inclined push plates 55. On the side of the inclined push plates 55 away from the U-shaped plate 51, engaging rods 551 are arranged, and the engaging rods 551 form an engaged and sliding relationship with the inclined guide rails 363 arranged on the blanking plate 36. When the blanking plate 36 moves horizontally in a reciprocating manner, the arranged inclined guide rails 363 can drive the engaging rods 551, causing the engaging rods 551 to drive the entire inclined push plate 55 to move reciprocally up and down;

[0060] On the vibrating sieve plate 54, telescopic rods 541 are arranged in an array, and the ends of the telescopic rods 541 away from the vibrating sieve plate 54 are fixedly connected to the feed bin 2. The telescopic rods 541 are used to support the vibrating sieve plate 54. At the same time, a telescopic rod 541 is also arranged on the mating plate 53. Under the action of the three telescopic rods 541, a stable lifting environment is provided for the vibrating sieve plate 54 and the mating plate 53.

[0061] Inside the lifting groove 512, a first spring 513 is movably arranged, and one end of the first spring 513 is in contact with the inclined push plate 55. The first spring 513 is used to provide elastic force. When the inclined push plate 55 is driven by the blanking plate 36 to reset, the first spring 513 provides certain assistance to complete the reset of the entire inclined push plate 55. Inside the sliding groove 511, support rods 514 are arranged in an array. A second spring 515 is sleeved outside the support rods 514, and one end of the second spring 515 is in contact with the convex block slide plate 52. A receiving cavity is opened on the side of the convex block slide plate 52 in contact with the second spring 515. This receiving cavity is used to receive a part of the compressed second spring 515 when the second spring 515 is compressed after the convex block slide plate 52 moves;

[0062] On the side of the U-shaped plate 51 away from the convex block slide plate 52, a mating gear 516 is movably arranged. On the side of the convex block slide plate 52 close to the mating gear 516, a rack 517 is arranged, and the rack 517 and the mating gear 516 form an engaging effect. The two racks 517 on the two convex block slide plates 52 are in a synchronous and mirror-image relationship with the mating gear 516. They move in opposite directions simultaneously but have the same moving distance. When the convex block slide plate 52 is driven by the rack 517, one side of the convex block slide plate 52 is relatively narrow, and during the movement of the convex block slide plate 52, it will not block the rack 517.

[0063] The flattening assembly 6 includes flattening plates 61 movably arranged on the vibrating sieve plate 54, and two flattening plates 61 are symmetrically arranged. One end of the flattening plate 61 close to the vibrating sieve plate 54 is comb-shaped, and the side of the flattening plate 61 facing outward has a certain arc, which is used to push the excess material to the outer area of the vibrating sieve plate 54 when the flattening plate 61 moves inside the vibrating sieve plate 54, improving the overall vibrating sieve effect. On the feeding bin 2, a fixed support cylinder 62 is arranged, and the fixed support cylinder 62 is fixedly connected to the feeding bin 2. The fixed support cylinder 62 is fixed to the feeding bin 2 through two support rods. At the same time, the fixed support cylinder 62 is integrally in a double-layer cylinder shape, and there is a certain sandwich cavity between the outer cylinder and the inner cylinder;

[0064] On the fixed support cylinder 62, a rotating cylinder 63 is movably arranged, and the rotating cylinder 63 is nested inside the fixed support cylinder 62. The overall rising height of the rotating cylinder 63 satisfies a 90-degree rotation of the rotating cylinder 63. A limiting rod 631 is arranged on the rotating cylinder 63. Through the engaging and sliding action between the limiting rod 631 and the spiral groove 621 of the inner cylinder on the fixed support cylinder 62, when the rotating cylinder 63 rises, it can rotate under the action of the limiting rod 631 and the spiral groove 621. The rotating rotating cylinder 63 can drive the flattening plate 61 to move, thereby flattening the piled-up materials;

[0065] There are positioning plates 64 symmetrically arranged outside the rotating cylinder 63, and a clamping rod is provided at one end of the positioning plate 64. A linear guide rail 65 is provided at one end of the flattening plate 61 close to the positioning plate 64, and the clamping rod provided on the linear guide rail 65 and the positioning plate 64 forms a clamping and sliding connection. The overall length of the linear guide rail 65 satisfies that the rotating cylinder 63 has sufficient sliding space when driving the positioning plate 64 to rotate 90 degrees. At the same time, the movement of the flattening plate 61 is the maximum diameter of the rotation of the positioning plate 64. When the flattening plate 61 moves to the maximum diameter, the inner contour of the vibrating sieve plate 54 can satisfy the overall movement of the flattening plate 61.

[0066] During the use process, the inclined push plate 55 provided is driven by the provided driving assembly 3 to move up and down. Under the up and down movement of the inclined push plate 55, the convex block slide plate 52 moves. Under the movement of the convex block slide plate 52, the mating plate 53 is continuously jacked up and then instantaneously drops under the condition of its own gravity without external force, forming a reciprocating up and down action. Through the formed up and down movement, an oscillating action is realized, thereby forming a certain vibration effect on the material falling on the vibrating sieve plate 54. At the same time, the up and down frequency of the vibrating sieve plate 54 is much greater than the reciprocating movement frequency of the blanking plate 36. Under the vibration of the high-frequency vibrating sieve plate 54 and at the same time in cooperation with the impact force generated on the vibrating sieve plate 54 when the blanking plate 36 moves, the material is under the action of two completely opposite acting forces, so that some of the agglomerated lumps generated due to electrostatic phenomena are shaken loose under this vibration, which is convenient for the subsequent air separation fan 7 to screen it. And the up and down movement of the entire vibrating sieve plate 54 will drive the flattening assembly 6 to evenly spread the material.

[0067] The remaining structures are the same as those of Embodiment 1.

[0068] Embodiment 3

[0069] Referring to Figure 1-15 , this is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is:

[0070] Linear grooves 542 are symmetrically opened on the vibrating sieve plate 54, and the linear grooves 542 and the flattening plate 61 form a clamping and sliding connection. A spiral groove 621 is opened inside the fixed support cylinder 62, and the spiral groove 621 is opened on the inner cylinder of the fixed support cylinder 62. Through the clamping action formed between the spiral groove 621 and the limiting rod 631, the rotating cylinder 63 can rotate 90 degrees when rising. A limiting rod 631 is arranged inside the rotating cylinder 63, and the limiting rod 631 and the spiral groove 621 form a clamping and sliding connection. The inside of the rotating cylinder 63 is a cavity, and under the action of the limiting rod 631, the rotating cylinder 63 is clamped on the fixed support cylinder 62.

[0071] The placing base 4 is provided with curved surface blocks 41 arranged in an array on one side close to the vibrating sieve plate 54. One side of the curved surface block 41 is curved, and a notch is penetrated through the curved surface block 41. A spherical rod 42 is movably arranged on the curved surface block 41. One end of the spherical rod 42 is spherical, and it contacts with the curved surface of the curved surface block 41 through its spherical shape, providing reciprocating movement for the spherical rod 42. A bearing plate 43 is arranged at the end of the spherical rod 42 away from the curved surface block 41. The whole bearing plate 43 has a certain inclination angle, which is more convenient for conveying materials during the whole tilting process. And the whole bearing plate 43 and the blanking plate 36 are engaged and slid through a square straight groove 361. A third spring 44 is sleeved outside the spherical rod 42, and the third spring 44 is used to reset the bearing plate 43.

[0072] During the use process, during the ascending process of the vibrating sieve plate 54, it will drive the positioning plate 64 clamped on the linear guide rail 65 to drive the rotating cylinder 63 to ascend synchronously. During the ascending process of the rotating cylinder 63, the limiting rod 631 arranged inside the rotating cylinder 63 will slide along the spiral groove 621 opened on the fixed support cylinder 62, causing the whole rotating cylinder 63 to rotate by 90 degrees. Under the rotation of the rotating cylinder 63, it drives the two spreading plates 61 to move towards each other. Under the movement of the spreading plates 61, the materials piled up on the vibrating sieve plate 54 are spread out, and the spread materials will increase the whole screening rate, avoiding excessive accumulation of materials on the vibrating sieve plate 54 and affecting the subsequent screening of copper powder.

[0073] The remaining structures are the same as those of Embodiments 2 and 3.

[0074] Embodiment 4

[0075] Refer to Figure 1-17 , which is the fourth embodiment of the present invention. The difference between this embodiment and the second and third embodiments is:

[0076] The driving component 3 includes a driving motor 31 arranged on one side of the feeding bin 2. A rotating shaft 32 is arranged on one side of the driving motor 31. A reciprocating groove rotating rod 33 is arranged at the end of the rotating shaft 32 away from the driving motor 31. A waveform reciprocating groove is opened on the reciprocating groove rotating rod 33, and the width between two adjacent waveform points of the reciprocating groove is slightly smaller than the maximum lateral moving distance of the inclined guide rail 363 arranged on the blanking plate 36. So that when the reciprocating groove rotating rod 33 rotates under the action of the rotating shaft 32, it can drive the blanking plate 36 on the whole supporting clamping plate 34 to reciprocate through the supporting insertion rod 35 arranged on the supporting clamping plate 34. A supporting clamping plate 34 is movably arranged inside the feeding bin 2. The supporting clamping plate 34 is used to support the blanking plate 36, and a T-shaped clamping block is arranged on the base 1 to clamp and limit the lower end of the supporting clamping plate 34, so that the supporting clamping plate 34 will not have position deviation and shaking during the whole moving process;

[0077] A support card board 34 is provided with a support insertion rod 35 on one side close to the reciprocating groove rotating rod 33, and the support insertion rod 35 is engaged and slidable with the reciprocating groove rotating rod 33. A blanking plate 36 is provided on the side of the support card board 34 away from the base 1. The blanking plate 36 is integrally U-shaped, and an inclined chamfer is provided on the side of the blanking plate 36 close to the vibrating sieve plate 54. So that the material falling on the blanking plate 36 can enter the bearing plate 43 through this chamfer under the overall vibration of the blanking plate 36, and the material is conveyed through the bearing plate 43 in a vibration direction different from that of the blanking plate 36.

[0078] A plurality of square straight grooves 361 are arranged in an array on the side of the blanking plate 36 close to the base 1, and the square straight grooves 361 are engaged and slidable with the bearing plate 43. When the blanking plate 36 is driven by the support card board 34 to move reciprocally, the bearing plate 43 is simultaneously driven to move reciprocally along the notch of the square straight groove 361, so that the material on the bearing plate 43 can be conveyed to the blanking port of the bearing plate 43 under the action of vibration. Finally, through the screening of the air separation fan 7, the copper powder therein is screened out. Fixed clamping rods 362 are symmetrically and movably arranged on the blanking plate 36, and one end of the fixed clamping rod 362 is fixedly connected to the feed bin 2. Oblique guide rails 363 are arranged in an array on the blanking plate 36, and the oblique guide rails 363 are engaged and slidable with the clamping rods 551.

[0079] An air separation fan 7 is arranged on the base 1, and the air separation fan 7 is located inside the feed bin 2. The air separation fan 7 is used to provide wind power. Through the action of different densities between the aluminum powder and the copper powder, the copper powder in the material is screened out and finally collected. A collection chamber 8 is arranged on the base 1. The inside of the collection chamber 8 is inclined, so as to enable the screened copper powder and aluminum powder to be conveyed to the outside and finally collected.

[0080] During the use process, the set driving motor 31 can drive the rotating shaft 32 to rotate. Under the action of the rotating shaft 32, the reciprocating groove rotating rod 33 is driven to rotate synchronously, so that the set support card board 34 drives the blanking plate 36 to move reciprocally. While the blanking plate 36 moves reciprocally, the engaged bearing plate 43 is driven to move along the direction of the square straight groove 361. The reciprocating movement of the blanking plate 36 can continuously impact the rubber pad on the vibrating sieve plate 54, so that the vibrating sieve plate 54 cooperates with its own up-and-down reciprocating movement under this impact to disperse the material falling on the vibrating sieve plate 54. During the movement of the entire blanking plate 36, the spherical rod 42 can slide on the curved surface block 41, and at the same time cooperate with the reset of the third spring 44 to make the bearing plate 43 form a reciprocating vibration, conveying the material to the front end of the air separation fan 7, so that the air separation fan 7 screens out the copper powder in the material.
