Description

Technical Field

[0001] The present application relates to the technical field of waste battery recycling, and in particular to a device and process for dismantling waste batteries by a non-salt water dry method. Background Art

[0002] Non-salt water dry dismantling of used batteries is an environmentally friendly battery recycling technology that avoids the use of water or chemical solutions, thereby reducing potential pollution to the environment. This technology usually involves physical methods to separate the various components in the battery, such as metals and plastics.

[0003] For example, a waste lithium battery disassembly and processing device with publication number CN118336189B relates to the field of lithium battery recycling technology. This prior art rotates the columnar positive and negative electrode materials in reverse after the shell is removed to create gaps between the layers of the materials, and then uses a crushing mechanism to crush the positive electrode material that is close to the negative electrode material to separate it from the negative electrode material, thereby obtaining pure positive electrode material and negative electrode material without sorting, which greatly reduces the sorting cost, reduces the difficulty of recycling battery materials, and improves the recycling efficiency.

[0004] However, the above-mentioned prior art still has some defects when dismantling waste batteries: 1. When dismantling waste lithium batteries, the above-mentioned patent application needs to first dismantle the battery shell, which increases the cost of dismantling waste batteries. Then, the internal materials of the waste batteries are placed in the device for dismantling into positive and negative electrode materials. However, the extrusion force generated by the crushing mechanism may not be able to completely crush the positive electrode material, and thus the positive and negative electrode materials may not be completely separated.

[0005] 2. The above patent application did not take into account the treatment of electrolyte during the disassembly of waste batteries. In the process of crushing the battery materials with a crushing mechanism, the electrolyte remaining in the waste batteries may leak out, thereby causing damage to the environment and even affecting the health of the operator.

[0006] 3. In the above patent application, when disassembling waste batteries, only cylindrical batteries can be disassembled, and because the size of the C-frame is fixed, only cylindrical batteries of a specific size can be disassembled by the device, thereby reducing the efficiency of disassembling waste batteries and increasing the cost of disassembling waste batteries.

DETAILED DESCRIPTION

[0046] The following is combined with Figures 1 to 8 This application is described in further detail.

[0047] The embodiment of the present application discloses a device for disassembling waste batteries by a non-salt water dry method. The waste batteries are disassembled to separate and collect the positive and negative electrode materials inside the batteries, and the electrolyte leaked during the disassembly of the waste batteries is also collected.

[0048] Embodiment 1:

[0049] Reference Figure 1 and Figure 2 A device for dismantling waste batteries by a non-salt water dry method comprises a box body 1, inside which a discharge mechanism 2, a dismantling mechanism 3 and a leakage mechanism 4 are sequentially installed along the height direction.

[0050] The discharge mechanism 2 includes a bidirectional threaded reciprocating rod 21. Two bidirectional threaded reciprocating rods 21 are symmetrically installed on both sides of the center line of the box body 1 along its width direction. Discharge plates 22 are installed on the bidirectional threaded reciprocating rods 21 along both sides of the center line of the box body 1 along the length direction through threaded rotation, which can discharge the battery to avoid explosion during disassembly.

[0051] The disassembling mechanism 3 includes a rotating shaft 31. Two rotating shafts 31 are symmetrically installed on both sides of the center line of the box body 1 along the width direction. Each rotating shaft 31 is provided with a magnetic spiral blade 32, which can adsorb the magnetic material in the battery material.

[0052] The leakage mechanism 4 includes a leakage arc plate 41 , which is disposed at the bottom of the corresponding magnetic spiral blade 32 , and has a plurality of leakage holes 42 , through which the electrolyte leaks into the bottom of the leakage arc plate 41 .

[0053] Among them, before disassembly, the discharge plate 22 corresponding to the shape of the waste battery, such as cylindrical or square, can be replaced, so that the device for disassembling waste batteries can adapt to the disassembly of waste batteries of different models, thereby saving the cost of the device. In the specific implementation process, the two-way threaded reciprocating rod 21 is first adjusted according to the size of the waste battery to be disassembled so that the distance between the discharge plates 22 matches the size of the waste battery, and then the waste battery is placed in the two discharge plates 22 for discharge, thereby ensuring that the waste battery can be disassembled in a non-powered state, avoiding accidents such as explosion or fire of charged waste batteries during disassembly, thereby affecting personnel safety. After the waste battery is discharged, the waste battery is preliminarily disassembled to avoid the waste battery being too large or the waste battery surface being relatively smooth, thereby reducing the subsequent disassembly rate and even possibly damaging the device.

[0054] Among them, the magnetic spiral blade 32 is magnetic when energized, and can absorb the magnetic material in the waste battery, and loses its magnetism when the power is off, and the curvature of the leakage arc plate 41 is consistent with the magnetic spiral blade 32, so it is convenient to transport and collect the internal materials of the waste battery that fall on the leakage arc plate 41. During specific work, the waste battery that has been initially disassembled falls into the disassembly mechanism 3 for further disassembly. At this time, the magnetic spiral blade 32 is energized, so that the magnetic material inside the waste battery can be absorbed by the magnetic spiral blade 32 during the disassembly of the waste battery by the disassembly mechanism 3, thereby realizing the separation of the internal materials of the waste battery. The negative electrode material contains magnetic substances such as iron, cobalt, and nickel. The magnetic spiral blades 32 adsorb these magnetic substances to achieve separation of the positive and negative electrodes, avoiding the positive and negative electrode materials from mixing together to increase the cost of subsequent separation of the positive and negative electrode materials, while improving the efficiency of disassembly and recycling of waste batteries; after the disassembly is completed, the non-magnetic material can be discharged from the box 1 and collected through the conveying characteristics of the magnetic spiral blades 32. After the non-magnetic material is conveyed, the magnetic spiral blades 32 are powered off, and the magnetic material falls on the leakage arc plate 41. At this time, the conveying characteristics of the magnetic spiral blades 32 can be used again to separate and collect the positive and negative electrode materials of the waste battery.

[0055] When disassembling used batteries, the electrolyte inside the batteries will leak out. If it is not collected, it may cause environmental pollution and damage human health. Therefore, the electrolyte leaked during the disassembly of used batteries will enter the bottom of the leakage arc plate 41 through the leakage hole 42. After all batteries are disassembled, the electrolyte under the leakage arc plate 41 is centrally processed.

[0056] Reference Figure 1 and Figure 3 In order to make the discharge mechanism 2 match batteries of different sizes, a plurality of discharge slots 23 are provided on the discharge plate 22 to discharge the waste batteries, and telescopic plates 24 are provided on both side walls of the discharge slots 23.

[0057] One end of one of the bidirectional threaded reciprocating rods 21 passing through the outside of the box body 1 is provided with a first motor 25, and a first pulley 26 is installed between the first motor 25 and the box body 1. The other end of the bidirectional threaded reciprocating rod 21 passing through the outside of the box body 1 is provided with a second pulley 27, and the first pulley 26 and the second pulley 27 are connected by belt transmission.

[0058] Before the disassembly begins, a discharge slot hole 23 that matches the shape and model of the waste battery can be selected, and the discharge plate 22 with the discharge slot hole 23 is placed on the bidirectional threaded reciprocating rod 21. At the same time, the discharge slot hole 23 can fix the waste battery, so that the waste battery will not jump or shake during the initial disassembly, thereby avoiding the low efficiency of the initial disassembly of the waste battery. In the specific implementation process, the first motor 25 is started, and under the joint action of the first pulley 26, the second pulley 27 and the belt, the bidirectional threaded reciprocating rod 21 starts to rotate in the same direction and moves with the discharge plate 22. When the distance between the discharge plates 22 matches the size of the waste battery, the waste battery is placed in the discharge slot hole 23 for discharge, so as to avoid accidents such as explosion or fire of the charged waste battery during disassembly, thereby threatening the safety of personnel.

[0059] Among them, the inclined surface on the top of the telescopic plate 24 can more effectively guide the waste batteries to be placed in the discharge slot hole 23. During operation, the telescopic plate 24 can tighten batteries of different sizes so that the waste batteries will not jump or shake during discharge or preliminary disassembly, thereby affecting the efficiency of discharge or disassembly.

[0060] Reference Figure 4 and Figure 5In order to facilitate the disassembly mechanism 3 to disassemble the waste battery more effectively, a preliminary disassembly assembly 28 is installed between the discharge plates 22. The preliminary disassembly assembly 28 includes a rotating shaft 281. The rotating shaft 281 is symmetrically arranged on both sides of the center line of the box body 1 along the width direction. A rotating handle 282 is installed at one end of the rotating shaft 281 in the box body 1. A planetary gear set 283 is installed on the side of the rotating handle 282 on the rotating shaft 281 close to the box body 1. The planetary gear set 283 includes a bidirectional gear disc 284, a planetary gear and a sun gear. The bidirectional gear disc 284 of the planetary gear set 283 is rotatably connected with the rotating handle 282 through a bearing.

[0061] During the specific implementation process, under external drive (not shown in the figure), the rotating shaft 281 starts to rotate and rotates together with the rotating handle 282. At this time, the preliminary disassembly component 28 begins to disassemble the discharged used batteries to avoid the used batteries being too large or having a smooth surface, which makes the subsequent disassembly efficiency low. The preliminary disassembly component 28 can break the outer shell of the used batteries or create many dents and damages on the surface of the used batteries to facilitate the disassembly mechanism 3 to disassemble the used batteries, thereby improving the disassembly efficiency.

[0062] Continue to refer to Figure 4 and Figure 5 A plurality of support rods 285 are installed between the planetary gear set 283 and the inner wall of the housing 1. One end of the support rod 285 away from the housing 1 is rotatably mounted on a planetary gear meshed with a bidirectional toothed disc 284 through a bearing.

[0063] A sun gear meshing with the planetary gear is installed on one end of the outer wall of the rotating shaft 281 corresponding to the planetary gear.

[0064] A linkage rod 286 is mounted on the rotating handle 282 , and a first linkage gear 287 meshing with the bidirectional gear plate 284 is mounted on one end of the linkage rod 286 away from the rotating handle 282 .

[0065] Among them, since the planetary gear and the support rod 285 are rotatably connected through the bearing, and the end of the support rod 285 away from the planetary gear is connected to the inner wall of the box body 1, the rotation of the rotating shaft 281 will not directly drive the planetary gear to rotate. During the specific implementation process, the rotating shaft 281 starts to rotate under external drive and drives the sun gear to rotate, and then the sun gear drives the planetary gear to rotate through the meshing transmission, and the planetary gear drives the two-way gear plate 284 to rotate through the meshing transmission, and then the two-way gear plate 284 drives the first linkage gear 287 to rotate through the meshing transmission, so that the preliminary disassembly component 28 can be operated and the used batteries can be preliminarily disassembled.

[0066] Reference Figure 4In order to enable the preliminary disassembly component 28 to disassemble the used batteries, a rotating rod 288 is rotatably penetrated by the end of the rotating handle 282 away from the rotating shaft 281 through a bearing, and a second linkage gear 289 meshing with the first linkage gear 287 is installed at the end of the rotating rod 288 close to the inner wall of the box body 1.

[0067] A plurality of arc-shaped blades 2810 are mounted on the rotating rod 288 to perform preliminary disassembly of the waste batteries.

[0068] During the specific implementation process, the rotating shaft 281 drives the rotating handle 282 to rotate, and the rotating handle 282 drives the rotating rod 288 to revolve. When the rotating rod 288 contacts the used battery, pressure is generated on the used battery. In addition, the first linkage gear 287 rotates and drives the second linkage gear 289 to rotate through meshing transmission. The rotation of the second linkage gear 289 drives the rotating rod 288 to rotate at the same time, and causes the arc blade 2810 to start rotating. Then, the rotating rod 288 and the arc blade 2810 can perform preliminary disassembly of the used battery under the joint action of revolution and rotation, so as to facilitate the subsequent disassembly mechanism 3 to further disassemble the used battery.

[0069] Reference Figure 6 Each magnetic spiral blade 32 is provided with a plurality of spikes 33 .

[0070] In the specific implementation process, the magnetic spiral blades 32 can not only adsorb the magnetic materials in the waste batteries, thereby separating the positive and negative electrode materials of the waste batteries, but also have the characteristics of being magnetic when the magnetic spiral blades 32 are powered on and losing magnetism when the power is off, and utilizing their conveying properties to collect the positive and negative electrode materials. In addition, the spikes 33 on the magnetic spiral blades 32 can cooperate with the preliminary disassembly assembly 28 to further disassemble the waste batteries, making the disassembly of the waste batteries more complete and improving the disassembly efficiency of the waste batteries.

[0071] Reference Figure 6 and Figure 7 In order to disassemble and collect the materials inside the used batteries, a plurality of diamond-shaped disassembly blades 34 are installed on the rotating shaft 31, which can directly disassemble the used batteries. A limiting ring 35 is installed at one end of each disassembly blade 34 away from the rotating shaft 31.

[0072] A scraper ring 36 is installed on the disassembling blade 34 to scrape the material on the disassembling blade 34 , and a return spring 37 is installed between the scraper ring 36 and the rotating shaft 31 .

[0073] A second motor 38 is disposed at one end of one of the rotating shafts 31 passing through the box body 1, and a driving gear 39 is installed on the rotating shaft 31 between the box body 1 and the second motor 38. A third linkage gear 310 meshing with the driving gear 39 is disposed at one end of the other rotating shaft 31 passing through the box body 1.

[0074] Among them, the reset spring 37 is located at the back of the disassembling blade 34, so when the disassembling blade 34 is working, the reset spring 37 will not affect the disassembling blade 34. In the specific implementation process, the second motor 38 is started to rotate the rotating shaft 31, and the rotation of the rotating shaft 31 drives the driving gear 39 to rotate. The driving gear 39 rotates and drives the third linkage gear 310 to rotate. The third linkage gear 310 drives another rotating shaft 31 to rotate, so the two rotating shafts 31 rotate in opposite directions, and then the magnetic spiral blades 32 on the two rotating shafts 31 and the disassembling blades 34 all rotate in opposite directions. This allows the waste batteries to be disassembled more thoroughly and completely. In the process of disassembling waste batteries, When the rotating shaft 31 rotates, centrifugal force is generated, causing the scraper ring 36 on the disassembling blade 34 to move toward the limit ring 35. The limit ring 35 can prevent the scraper ring 36 from being thrown out of the disassembling blade 34 under the action of the centrifugal force. When the disassembly is completed, the scraper ring 36 begins to reset under the action of the reset spring 37. During its reset process, the scraper ring 36 can clean some battery materials attached to the disassembly blade 34, thereby ensuring the recovery rate of the internal materials of the waste battery. At the same time, cleaning the disassembly blade 34 can ensure that the disassembly blade 34 can still effectively disassemble the waste battery during the next disassembly work, thereby improving the disassembly efficiency of the waste battery.

[0075] Embodiment 2:

[0076] Reference Figure 8 In order to recycle the electrolyte in the waste battery, the leakage mechanism 4 also includes a liquid storage tank 43, the top of the liquid storage tank 43 is sealed with the leakage arc plate 41, and a liquid outlet pipe 44 is arranged on one side of the bottom of the liquid storage tank 43.

[0077] During the specific implementation process, when the used batteries are initially disassembled and completely disassembled, the electrolyte leaked from the used batteries flows into the liquid storage tank 43 through the leakage hole 42 on the leakage arc plate 41 for temporary storage to prevent the electrolyte from causing damage to human health. After the magnetic spiral blades 32 discharge all the magnetic materials and non-magnetic materials from the box body 1, the electrolyte in the liquid storage tank 43 is discharged and collected through the liquid outlet pipe 44.

[0078] Reference Figure 2 In order to allow the waste battery materials to be discharged from the box 1 and collected, a discharge port 11 is provided on the side of the box 1 away from the second motor 38, and a valve 12 is provided on the discharge port 11.

[0079] Among them, the size of the battery material after disassembly is larger than the aperture of the leakage hole 42. In the specific implementation process, after the waste battery in the disassembly mechanism 3 is completely disassembled, the valve 12 is opened, and the non-magnetic material in the waste battery can be discharged and collected through the discharge port 11 through the conveying action of the magnetic spiral blade 32. After the non-magnetic material is discharged, the magnetic spiral blade 32 is powered off, the magnetic spiral blade 32 loses its magnetism, and the magnetic material attached to it falls on the leakage arc plate 41, and then under the conveying action of the magnetic spiral blade 32, the magnetic material is discharged and collected through the discharge port 11, thereby realizing the separation and collection of the positive and negative electrode materials of the battery.

[0080] Finally, the present invention also provides a process for dismantling waste batteries by a non-salt water dry method, and the method for using the process comprises the following steps:

[0081] S1: Battery discharge, firstly adjust the bidirectional threaded reciprocating rod 21 so that the spacing between the discharge plates 22 matches the battery size, and then put the battery into the discharge slot 23 to discharge the battery;

[0082] S2: Preliminary disassembly, using the preliminary disassembly component 28 to perform preliminary disassembly on the battery, which can cause cracks or dents to appear on the waste battery, making it easier for the disassembly mechanism 3 to disassemble;

[0083] S3: Complete disassembly, further disassembling the battery after the preliminary disassembly assembly 28 is disassembled, and the battery is completely disassembled to facilitate the sorting and collection of materials;

[0084] S4: Magnetic absorption of leaked liquid. According to the different characteristics of the internal materials of the battery, the magnetic spiral blade 32 is energized to make it magnetic, thereby adsorbing the magnetic material in the battery. In addition, the electrolyte in the battery is collected by the leaking arc plate 41 and the liquid storage tank 43;

[0085] S5: Material collection. The non-magnetic material in the battery is discharged from the box 1 through the conveying characteristics of the magnetic spiral blade 32 and collected. After the non-magnetic material is discharged, the magnetic spiral blade 32 is powered off to make it lose its magnetism, and the magnetic material falls on the leakage arc plate 41. At this time, the magnetic material is discharged and collected through the conveying characteristics of the magnetic spiral blade 32.

[0086] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
