Description

Technical Field

[0001] The invention relates to the technical field of battery component recycling and regeneration, in particular to an automatic positive and negative electrode waste sorting device for recycling waste batteries. Background Art

[0002] In today's society, with the widespread use of electronic devices, batteries, as an indispensable energy supply component, have seen a sharp increase in usage. The generation of a large number of waste batteries has not only caused serious environmental pollution, but also wasted a lot of resources.

[0003] For example, the patent "CN112086702A A method and device for automated and precise sorting of power batteries" discloses a technical solution for sorting positive and negative electrode waste of batteries by means of magnetic sorting principles and electrostatic sorting principles. However, this technical solution faces a key problem, that is, in order to ensure the sorting effect during sorting, strict requirements are required on the thickness of the waste. If the thickness of the waste is large, it will seriously affect the sorting effect. However, this operation will inevitably reduce the sorting efficiency and sometimes it is difficult to meet the work needs; finally, the existing sorting equipment performs poorly in terms of stability and reliability. Once a key component fails, it often causes the entire sorting device to be paralyzed and unable to work normally. This not only interrupts the production process, but also causes a lot of time and resource waste, seriously affecting the continuity and stability of production. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic sorting device for positive and negative electrode waste materials for recycling waste batteries to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic sorting device for positive and negative waste materials for recycling used batteries, the sorting device comprising a base, a body is arranged above the base, a second sorting chamber and a distributor are arranged oppositely at the left and right ends of the body, a first sorting chamber is arranged between the second sorting chamber and the distributor, a magnetic separation mechanism and a conveying mechanism are arranged inside the first sorting chamber, the magnetic separation mechanism is arranged above the conveying mechanism, an electrostatic separation mechanism is arranged inside the second sorting chamber, and an eddy current separation mechanism is arranged below the electrostatic separation mechanism. The magnetic separation mechanism is connected to the electrostatic separation mechanism through a shunt mechanism. When the present invention is working, the staff needs to send the mixed positive and negative electrode waste obtained after mechanical crushing into the distributor, and then turn on the distributor, the magnetic separation mechanism, the electrostatic separation mechanism, and the eddy current separator. The positive and negative electrode wastes are sent to the conveying mechanism through the distributor. When the positive and negative electrode wastes move on the conveying mechanism, the iron powder in the positive and negative electrode wastes is separated out by the magnetic separation mechanism, the positive electrode wastes such as nickel cobalt manganese oxide are separated out by the electrostatic separation mechanism, and the graphite powder, copper powder, and aluminum powder are separated by the eddy current separator.

[0006] Furthermore, the magnetic separation mechanism includes magnetic rollers, a first rotating motor and a first mounting frame, the first mounting frames are provided with two groups, the two groups of first mounting frames are relatively arranged on both sides above the conveying mechanism, the magnetic rollers are provided with several groups, the several groups of magnetic rollers are horizontally arranged between the two groups of first mounting frames, each group of magnetic rollers is provided with a group of collecting covers on the side close to the distributor, each group of collecting covers is in contact with the surface of a group of magnetic rollers, one group of the first mounting frames is provided with a first belt drive assembly inside, and the first rotating motor is connected to the several groups of magnetic rollers through the first belt drive assembly.

[0007] Furthermore, the electrostatic sorting mechanism includes a second rotating motor, a second mounting frame, a collection box and a grounding roller. The second mounting frame is provided with two groups, and the two groups of second mounting frames are relatively arranged on both sides of the interior of the second sorting chamber. A through hole is provided below the second sorting chamber. The collection box is provided below the base and aligned with the through hole. The grounding rollers are provided with several groups, and a group of corona electrodes are provided above the side of each group of grounding rollers away from the conveying mechanism. The waste is evenly conveyed to the top of several groups of grounding rollers through the diversion mechanism, and a second belt drive assembly is provided inside one group of the second mounting frames. The second rotating motor is connected to several groups of grounding rollers through the second belt drive assembly. A collection frame and a guide plate are provided inside the collection box. Several groups of collection frames are provided, and each group of collection frames is aligned with a group of grounding rollers. A group of brushes are provided near the end of the grounding roller away from the corona electrode.

[0008] When the positive and negative electrode wastes move on the conveying mechanism, the first rotating motor drives several groups of magnetic rollers to rotate through the first belt transmission assembly, and the iron powder in the positive and negative electrode wastes is adsorbed by the magnetic rollers. When the area of ​​the magnetic roller adsorbing the iron powder contacts the collecting cover, the iron powder is scraped away through the side of the collecting cover. At this time, the iron powder will fall into the collecting cover. Then, after magnetic separation, the positive and negative electrode wastes will move along the diversion mechanism to the top of several groups of grounding rollers. Under the action of static electricity, graphite powder, copper powder, and aluminum powder will directly fall onto the guide plate, and positive electrode wastes such as nickel cobalt manganese oxide will adhere to the surface of the grounding roller and rotate with the grounding roller, and finally be scraped into the collecting rack by the brush. The guide plate in the present invention is tiltedly arranged in the collecting box so that the graphite powder, copper powder, and aluminum powder fall onto the guide plate and then slide onto the eddy current sorting mechanism, and the graphite powder is separated by the eddy current sorting mechanism. , copper powder and aluminum powder are separated. Compared with the current sorting device, the present invention can process more positive and negative electrode wastes at one time, avoiding the problem of less waste being processed at a single time, so that the sorting efficiency is difficult to meet the work needs. In addition, the present invention can effectively improve the sorting effect and reduce the phenomenon of omission by setting several groups of magnetic rollers and several groups of grounding rollers. On the other hand, the several groups of magnetic rollers and several groups of grounding rollers in the present invention work independently. When a group of magnetic rollers or grounding rollers fails, the remaining magnetic rollers and grounding rollers will continue to operate. At this time, the staff only needs to reduce the amount of positive and negative electrode wastes delivered to the conveying mechanism to ensure the normal operation of the sorting. Through the above technical scheme, the present invention effectively reduces the risk of overall paralysis of the sorting device due to local failures, thereby effectively ensuring the continuity and stability of production.

[0009] Furthermore, the conveying mechanism includes a conveying roller and a conveying belt. Several groups of vibration elements are arranged inside the conveying belt. Each group of vibration elements is aligned with a group of magnetic rollers. When the positive and negative electrode waste materials move on the conveying mechanism, the positive and negative electrode waste materials can vibrate up and down through the several groups of vibration elements, so as to improve the efficiency of the magnetic rollers in adsorbing the iron powder in the positive and negative electrode waste materials.

[0010] Furthermore, the magnetic roller is provided with a first electromagnet, a relay and a brush. The first electromagnet is provided in six groups, and the six groups of first electromagnets are evenly distributed in a ring shape in the magnetic roller. The relay is provided in six groups, and the six groups of relays are all arranged at one end of the magnetic roller away from the first rotating motor. Each group of first electromagnets is connected to the brush through a group of relays, and the brush is connected to an external power supply.

[0011] Furthermore, a plurality of groups of induction disks are arranged in a first mounting frame far away from the first rotating motor, each group of induction disks is aligned with a group of magnetic rollers, a light-emitting element is arranged at one end of the induction disk close to the collecting cover, and the light-emitting element is an arc-shaped structure, and six groups of photoelectric sensor elements are arranged at one end of the magnetic roller close to the induction disk, each group of photoelectric sensor elements is aligned with a group of first electromagnets, and each group of photoelectric sensor elements is electrically connected to a group of relays.

[0012] The iron powder in the positive and negative pole waste materials is adsorbed by the six groups of first electromagnets in the magnetic roller, and the magnetic roller will continue to rotate at the same time. Since six groups of photoelectric sensor elements are arranged at one end of the magnetic roller close to the induction disk, the six groups of photoelectric sensor elements will intermittently align with the light-emitting elements at one end of the induction disk close to the collection cover. During the sorting process of the present invention, the light-emitting elements will continue to emit light. When a group of photoelectric sensor elements is close to the collection cover, the group of photoelectric sensor elements will align with the light-emitting elements and generate a group of electrical signals to stop the relay close to the collection cover and the first electromagnet close to the collection cover. At this time, the iron powder adsorbed by the first electromagnet close to the collection cover will fall into the collection cover under the action of gravity and the side resistance of the collection cover. Through the above technical scheme, on the one hand, the present invention can adjust the magnetic force of the magnetic roller to adsorb iron powder according to needs, thereby improving the sorting effect. On the other hand, the present invention can make the iron powder fall into the collection cover easily, and avoid the magnetic force of the magnetic roller to adsorb iron powder being too strong, so that the iron powder on the surface of the magnetic roller cannot be completely scraped into the collection cover by the resistance of the side of the collection cover alone.

[0013] Furthermore, the diversion mechanism includes a diversion plate, which is provided in several groups, and each group of diversion plates is arranged above a group of grounded rollers. The conveying mechanism is provided with a rotating shaft at one end close to the diversion mechanism, and a movable plate is provided at one end of the rotating shaft close to the diversion mechanism, and a swing motor is provided at the side end of the rotating shaft.

[0014] Furthermore, a limit seat is provided below the movable plate, and the swing angle of the diverter plate is limited by the limit seat. The positive and negative electrode wastes in the present invention will fall into the movable plate after magnetic separation, and the movable plate is controlled to swing above the limit seat by a swing motor, so that the positive and negative electrode wastes after magnetic separation are evenly distributed on several groups of diverter plates, so that the positive and negative electrode wastes after magnetic separation are moved above several groups of grounded rollers, and the positive and negative electrode wastes after magnetic separation are electrostatically separated and treated by several groups of grounded rollers and several groups of corona electrodes.

[0015] Furthermore, a group of adjustment components is arranged above each group of diverter plates, and the adjustment components include a fixed seat, a second electromagnet and an adjustment block. The second electromagnet is arranged at an end of the fixed seat away from the diverter plate, and the adjustment block is arranged at an end of the fixed seat close to the diverter plate. The adjustment block and the fixed seat are connected by a compression spring, and a magnetic block is embedded in the end of the adjustment block close to the second electromagnet. When the positive and negative waste materials after magnetic separation are evenly distributed on the diverter plate, the staff can turn on the second electromagnet to generate a group of magnetic fields that repel the adjustment block through the second electromagnet to change the distance between the adjustment block and the diverter plate. When the positive and negative waste materials after magnetic separation flow between the adjustment block and the diverter plate, the adjustment component can level the waste materials on the one hand, and on the other hand, it is convenient for the staff to adjust the thickness of the positive and negative waste materials according to the electrostatic adsorption force of the grounding roller to avoid excessive thickness of the positive and negative waste materials, so that the electrostatic separation is incomplete.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the current sorting device, the present invention is provided with several groups of magnetic rollers and several groups of grounding rollers, and at the same time, several groups of magnetic rollers are arranged above the conveying mechanism, so that the present invention can process more positive and negative electrode waste at one time, avoiding processing less waste at a single time, so that the sorting efficiency is difficult to meet the work needs. In addition, the present invention can also effectively improve the sorting effect and reduce the phenomenon of omission by setting several groups of magnetic rollers and several groups of grounding rollers. At the same time, the several groups of magnetic rollers and several groups of grounding rollers in the present invention work independently. When a group of magnetic rollers or grounding rollers fails, the remaining magnetic rollers and grounding rollers will continue to operate. At this time, the staff only needs to reduce the amount of positive and negative electrode waste sent to the conveying mechanism to ensure the normal operation of the sorting. Through the above technical scheme, the present invention effectively reduces the sorting The risk of the selection device being paralyzed as a whole due to local failure is reduced, thereby effectively ensuring the continuity and stability of production. The present invention also has six groups of photoelectric sensor elements arranged at one end of the magnetic roller close to the induction disk, and an arc-shaped light-emitting element is arranged on the induction disk, so that when the area where the magnetic roller adsorbs iron powder is close to the collecting cover, the iron powder will fall into the collecting cover under the action of gravity and the side resistance of the collecting cover, thereby preventing the magnetic force of the magnetic roller adsorbing the iron powder from being too strong, so that the iron powder on the surface of the magnetic roller cannot be completely scraped into the collecting cover by the resistance of the side of the collecting cover alone. Finally, the present invention is also provided with an adjusting component, which can level the positive and negative waste materials to be electrostatically sorted on the one hand, and facilitate the staff to adjust the thickness of the positive and negative waste materials according to the electrostatic adsorption force of the grounding roller on the other hand, thereby preventing the thickness of the positive and negative waste materials from being too large, resulting in incomplete electrostatic sorting.

[0021] like Figure 2-Figure 6 As shown, the magnetic separation mechanism 4 includes a magnetic roller 41, a first rotating motor 42 and a first mounting frame 43. Two groups of first mounting frames 43 are provided. The two groups of first mounting frames 43 are relatively arranged on both sides above the conveying mechanism 7. Several groups of magnetic rollers 41 are provided. Several groups of magnetic rollers 41 are horizontally arranged between the two groups of first mounting frames 43. A group of collecting covers 411 are provided on the side of each group of magnetic rollers 41 close to the distributor 3. Each group of collecting covers 411 is in contact with the surface of a group of magnetic rollers 41. A first belt transmission assembly is provided inside one group of first mounting frames 43. The first rotating motor 42 is connected to the several groups of magnetic rollers 41 through the first belt transmission assembly.

[0022] like Figure 2-Figure 4 , Figure 10-11 As shown, the electrostatic sorting mechanism 5 includes a second rotating motor 51, a second mounting frame 52, a collecting box 53 and a grounding roller 54. The second mounting frame 52 is provided with two groups, and the two groups of second mounting frames 52 are relatively arranged on both sides of the interior of the second sorting chamber 22. A through hole is provided below the second sorting chamber 22. The collecting box 53 is arranged below the base 1 and is aligned with the through hole. The grounding roller 54 is provided with a plurality of groups. A group of corona electrodes 541 are provided above the side of each group of grounding rollers 54 away from the conveying mechanism 7. The corona electrodes 541 are provided to the grounding rollers 54 through the shunting mechanism 8. The waste is evenly transported to the top of several groups of grounded rollers 54, wherein a second belt drive assembly is arranged inside one group of second mounting frames 52, and the second rotating motor 51 is connected to several groups of grounded rollers 54 through the second belt drive assembly. A collection rack 531 and a guide plate 532 are arranged inside the collection box 53, and several groups of collection racks 531 are arranged, and each group of collection racks 531 is aligned with a group of grounded rollers 54, and a group of brushes are arranged at one end of each group of collection racks 531 close to the grounded rollers 54 and away from the corona electrode 541.

[0023] When the present invention is in operation, the staff needs to feed the mixed positive and negative electrode waste obtained after mechanical crushing into the distributor 3, and then turn on the distributor 3, the first rotating motor 42 and the second rotating motor 51, and feed the positive and negative electrode waste to the conveying mechanism 7 through the distributor 3. When the positive and negative electrode waste moves on the conveying mechanism 7, the first rotating motor 42 drives a plurality of groups of magnetic rollers 41 to rotate through the first belt transmission assembly, and the iron powder in the positive and negative electrode waste is adsorbed by the magnetic rollers 41. When the area where the iron powder is adsorbed by the magnetic rollers 41 is aligned with the collecting cover 4 11, the iron powder is scraped away by the side of the collecting cover 411, and the iron powder will fall into the collecting cover 411 at this time.

The guide plate 532 in the present invention is inclined. It is placed in the collecting box 53 so that graphite powder, copper powder and aluminum powder can fall onto the guide plate 532 and then slide onto the eddy current sorting mechanism 6, and the graphite powder, copper powder and aluminum powder can be separated by the eddy current sorting mechanism 6. Compared with the current sorting device, the present invention can process more positive and negative electrode waste at one time, avoiding the single processing of less waste, so that the sorting efficiency is difficult to meet the work needs. In addition, the present invention can effectively improve the sorting effect and reduce the phenomenon of leakage by setting several groups of magnetic rollers 41 and several groups of grounding rollers 54. On the other hand, the several groups of magnetic rollers 41 and several groups of grounding rollers 54 in the present invention work independently. When a group of magnetic rollers 41 or grounding rollers 54 fails, the remaining magnetic rollers 41 and grounding rollers 54 will continue to run. At this time, the staff only needs to reduce the amount of positive and negative electrode waste sent to the conveying mechanism 7 to ensure the normal operation of the sorting. Through the above technical scheme, the present invention effectively reduces the risk of overall paralysis of the sorting device due to local failure, thereby effectively ensuring the continuity and stability of production.

[0024] like Figure 5 As shown, the conveying mechanism 7 includes a conveying roller and a conveying belt. A plurality of groups of vibration elements 71 are arranged inside the conveying belt. Each group of vibration elements 71 is aligned with a group of magnetic rollers 41. When the positive and negative electrode waste materials move on the conveying mechanism 7, the plurality of vibration elements 71 can cause the positive and negative electrode waste materials to vibrate up and down, so as to improve the efficiency of the magnetic rollers 41 in adsorbing the iron powder in the positive and negative electrode waste materials.

[0025] like Figure 5 , Fig. 9As shown, a first electromagnet 412, a relay 414 and a brush 415 are provided in the magnetic roller 41. Six groups of first electromagnets 412 are provided, and the six groups of first electromagnets 412 are evenly distributed in a ring shape in the magnetic roller 41. Six groups of relays 414 are provided, and the six groups of relays 414 are all provided at one end of the magnetic roller 41 away from the first rotating motor 42. Each group of first electromagnets 412 is connected to the brush 415 through a group of relays 414, and the brush 415 is connected to an external power supply.

[0026] like Figure 6-Figure 9 As shown, a plurality of groups of induction disks 431 are arranged in a first mounting frame 43 away from the first rotating motor 42, each group of induction disks 431 is aligned with a group of magnetic rollers 41, a light-emitting element 4311 is arranged at one end of the induction disk 431 close to the collecting cover 411, and the light-emitting element 4311 is an arc-shaped structure, and six groups of photoelectric sensor elements 413 are arranged at one end of the magnetic roller 41 close to the induction disk 431, each group of photoelectric sensor elements 413 is aligned with a group of first electromagnets 412, and each group of photoelectric sensor elements 413 is electrically connected to a group of relays 414.

[0027] When the present invention is working, the six groups of first electromagnets 412 in the magnetic roller 41 adsorb the iron powder in the positive and negative electrode wastes, and the magnetic roller 41 will continue to rotate (the rotation direction is as follows Figure 5 As shown in the figure, since six groups of photoelectric sensor elements 413 are arranged at one end of the magnetic roller 41 close to the induction disk 431, the six groups of photoelectric sensor elements 413 will intermittently align with the light-emitting elements 4311 at one end of the induction disk 431 close to the material collecting cover 411. During the sorting process of the present invention, the light-emitting elements 4311 will continue to emit light. When a group of photoelectric sensor elements 413 is close to the material collecting cover 411, the group of photoelectric sensor elements 413 will align with the light-emitting elements 4311 and generate a group of electrical signals, so that the relay 414 close to the material collecting cover 411 and the relay 414 close to the material collecting cover 411 will be aligned with the light-emitting elements 4311. The first electromagnet 412 stops working. At this time, the iron powder adsorbed by the first electromagnet 412 close to the collecting cover 411 will fall into the collecting cover 411 under the action of gravity and the side resistance of the collecting cover 411. Through the above technical scheme, on the one hand, the present invention can adjust the magnetic force of the magnetic roller 41 to adsorb iron powder as needed, thereby improving the sorting effect. On the other hand, the present invention can make the iron powder easily fall into the collecting cover 411, and avoid the magnetic force of the magnetic roller 41 to adsorb iron powder being too strong, so that the iron powder on the surface of the magnetic roller 41 cannot be completely scraped into the collecting cover 411 by the resistance of the side of the collecting cover 411 alone.

[0028] like Fig.10As shown, the diverter mechanism 8 includes a diverter plate 81, and the diverter plate 81 is provided in several groups. Each group of diverter plates 81 is arranged above a group of grounded rollers 54. A rotating shaft 72 is provided at one end of the conveying mechanism 7 close to the diverter mechanism 8, and a movable plate 721 is provided at one end of the rotating shaft 72 close to the diverter mechanism 8. A swing motor is provided at the side end of the rotating shaft 72.

[0029] like Fig.10 As shown, a limit seat 83 is provided below the movable plate 721 , and the limit seat 83 is used to limit the swing angle of the diverter plate 81 .

[0030] After magnetic separation, the positive and negative electrode waste materials in the present invention will fall into the movable plate 721, and the movable plate 721 is controlled by a swing motor to swing above the limit seat 83, so that the positive and negative electrode waste materials after the magnetic separation are evenly distributed on several groups of distribution plates 81, so that the positive and negative electrode waste materials after the magnetic separation are moved above several groups of grounding rollers 54, and the positive and negative electrode waste materials after the magnetic separation are electrostatically separated by several groups of grounding rollers 54 and several groups of corona electrodes 541.

[0031] like Fig.10 As shown, a group of adjustment components 82 are arranged above each group of diverter plates 81, and the adjustment components 82 include a fixed seat 821, a second electromagnet 822 and an adjustment block 823. The second electromagnet 822 is arranged at one end of the fixed seat 821 away from the diverter plate 81, and the adjustment block 823 is arranged at one end of the fixed seat 821 close to the diverter plate 81. The adjustment block 823 is connected to the fixed seat 821 through a compression spring, and a magnetic block is embedded in the end of the adjustment block 823 close to the second electromagnet 822.

[0032] When the positive and negative waste materials after magnetic separation are evenly distributed on the diverter plate 81, the staff can turn on the second electromagnet 822 to generate a set of magnetic fields that repel the adjustment block 823 through the second electromagnet 822 to change the distance between the adjustment block 823 and the diverter plate 81. When the positive and negative waste materials after magnetic separation flow between the adjustment block 823 and the diverter plate 81, the adjustment component 82 can level the waste materials on the one hand, and on the other hand, it is convenient for the staff to adjust the thickness of the positive and negative waste materials according to the electrostatic adsorption force of the grounding roller 54 to avoid excessive thickness of the positive and negative waste materials, resulting in incomplete electrostatic separation.

[0033] The working principle of the present invention is as follows: during operation, the mixed positive and negative electrode waste obtained after mechanical crushing is fed into the distributor 3, and then the distributor 3, the first rotating motor 42 and the second rotating motor 51 are turned on, and the positive and negative electrode waste are fed to the conveying mechanism 7 through the distributor 3. When the positive and negative electrode waste moves on the conveying mechanism 7, the first rotating motor 42 drives a plurality of groups of magnetic rollers 41 to rotate through the first belt transmission assembly, and the iron powder in the positive and negative electrode waste is adsorbed by the magnetic rollers 41. When the area where the iron powder is adsorbed by the magnetic rollers 41 contacts the collecting cover 411, the iron powder is scraped away through the side of the collecting cover 411, and the iron powder will fall into the collecting cover. In the cover 411, the positive and negative electrode wastes after magnetic separation will move along the diversion mechanism 8 to the top of several groups of grounding rollers 54. Under the action of static electricity, graphite powder, copper powder and aluminum powder will fall directly onto the guide plate 532, and the positive electrode wastes such as nickel cobalt manganese oxide will adhere to the surface of the grounding roller 54 and rotate with the grounding roller 54, and finally be scraped into the collection rack 531 by the brush. The guide plate 532 in the present invention is tiltedly arranged on the collection box 53, so that the graphite powder, copper powder and aluminum powder fall onto the guide plate 532 and then slide onto the eddy current sorting mechanism 6, and the graphite powder, copper powder and aluminum powder are separated by the eddy current sorting mechanism 6.
