Description

Technical Field

[0001] This application relates to the technical field of pollutant recovery, and particularly to a lithium battery disassembly self-cleaning recovery system. Background Art

[0002] A battery, with the English name Battery; refers to a cup, trough or other container or part of the space of a composite container containing an electrolyte solution and metal electrodes to generate current, and is a device that can convert chemical energy into electrical energy. Due to its energy storage effect, simple battery structure, convenient portability, easy charging and discharging operations, and being unaffected by external climate and temperature, with stable and reliable performance, it plays a great role in all aspects of modern social life.

[0003] Due to the large-scale use of batteries, the ownership of batteries has increased sharply in recent years. And because of the limitation of the battery's own service life, after the service life of the battery is reached, the recycling of lithium batteries becomes particularly important. If the batteries are not recycled properly, it will cause the release of harmful substances inside the batteries such as heavy metals, which will affect life and the environment. Based on this, in the prior art, such as the Chinese patent with the publication number CN103311601B, it discloses a lithium battery processing device, specifically including a shelling device, a crushing device, a screening device and a roasting device. The shelling device is connected to the crushing device, the crushing device is connected to the screening device, and the screening device is connected to the roasting device through belt conveyors. Through the mutual cooperation of the above-mentioned crushing device, screening device, etc., the recycling and crushing treatment of lithium batteries are realized, and this solution has the effects of less environmental pollution and high recovery and utilization degree of metals.

[0004] However, as is well known, the materials inside lithium batteries include lithium cobaltate, lithium manganate, lithium iron phosphate, ternary materials, natural graphite, artificial graphite, etc. And most of the materials inside are in powder form. For the above-mentioned lithium battery processing device, during the process of crushing the battery, a blower is used to blow and separate the crushed materials. At this time, it is extremely easy for the powdered materials to fly everywhere. On the one hand, it is difficult to collect and recycle the materials, and on the other hand, it will also cause the operator to inhale these harmful substances, affecting the working environment in the workshop. Based on this, there is still room for improvement in the existing lithium battery recycling technologies. Summary of the Invention

Detailed implementation manners

[0031] The following further elaborates on this application in conjunction with the attached Figure 1-10 drawings.

[0032] An embodiment of the present application discloses a self-cleaning recycling system for lithium battery disassembly. Specifically, it includes a crushing device 2 and a recycling device 3 for recycling the internal materials of the crushed lithium battery. The crushing device 2 can quickly crush the lithium battery. And after crushing, the recycling device 3 seals and recycles materials such as lithium cobaltate, lithium manganate, and lithium iron phosphate inside the crushed lithium battery, which can effectively ensure the cleanliness and safety of the working environment, have a higher recycling efficiency for various materials, are convenient and fast to operate, and improve the convenience of actual operation.

[0033] Refer to Figure 1 , 2 As shown in the figure, it is a structural schematic diagram of the crushing device 2 of the present application. In this embodiment, the crushing device 2 includes a material crushing box 11 and a material breaking device 4. Specifically, the material crushing box 11 includes a fixed substrate 12 fixed on the base. A sealing cover 13 is rotatably connected above the fixed substrate 12. Both the sealing cover 13 and the material crushing box 11 are made of plastic materials. After the material crushing box 11 covers the fixed substrate 12, a sealed operation area 14 is formed. When actually crushing the lithium battery, the operation is carried out in the sealed operation area 14, which can prevent the debris generated during the crushing of the lithium battery from splashing and improve the actual material recycling effect. In addition, the material breaking device 4 is arranged between the fixed substrate 12 and the sealing cover 13 to perform the crushing operation on the lithium battery. The material breaking device 4 is used to quickly break the outer shell of the lithium battery so that the powder material inside the lithium battery can quickly fall to achieve actual recycling.

[0034] After the battery outer shell is broken, the recycling device 3 is used to recycle the internal materials of the battery. That is, the recycling operation is carried out through the recycling device 3 in this embodiment. Specifically, the recycling device 3 is a symmetrically arranged suction tube 31. One end of the suction tube 31 is connected to a waste collection box 33 through a suction pipe 32. It should be noted that the suction force of the suction tube 31 is driven by an air extractor, and the crushed material is transferred to the waste collection box 33 through the suction tube 31. A filter screen (not shown in the figure) is provided in the waste collection box 33 to achieve dust-free collection of the powder material.

[0035] In addition, a through hole 121 for the suction pipe 32 to pass through is opened on the fixed substrate 12 to facilitate the installation of the suction pipe 32. And one-way air inlet holes 131 are symmetrically opened on the upper side of the material crushing box 11 to prevent the phenomenon that negative pressure is formed in the material crushing box 11 and the material cannot be sucked.

[0036] Refer to Figure 3As shown, for the structural schematic of the material breaker 4 in this embodiment, in this embodiment, the material breaker 4 includes a fixed block 41, a driving motor 42, a material breaking drill bit 43, a circulating feeding system 44, and a fixing device 45; specifically, the fixed block 41 is vertically installed on the upper side of the fixed substrate 12 and extends into the sealing operation area 14. In this embodiment, the fixed block 41 is a cylindrical structure made of metal material. The driving motor 42 is installed in the middle of the fixed block 41. An installation groove 411 is opened on the fixed block 41, the upper part of which communicates with the outside and is for installing the driving motor 42. The material breaking drill bit 43 is connected to the driving motor 42 and is arranged upward. That is, actually driven by the driving motor 42, the material breaking drill bit 43 can be driven to rotate to realize the breaking operation of the battery shell. The circulating feeding system 44 is arranged above the outside of the sealing cover 13 ( Figure 2 as shown), to realize the timed circulation of conveying lithium batteries to the position of the material breaking drill bit 43, forming a circulating treatment effect; the fixing device 45 is located above the fixed block 41 to fix the lithium battery. That is, actually during the process of breaking the lithium battery, the fixing device 45 can fix the lithium battery shell to prevent the reduction of the breaking effect on the battery shell due to the self-rotation of the lithium battery; and, a feeding hole 111 is opened on the crushing box 11. The feeding hole 111 corresponds to the installation groove 411 on the fixed block 41. When the lithium battery enters the crushing box 11 from the feeding hole 111, it can be inserted into the installation groove 411.

[0037] Referring to Figure 3 and 4 As shown, for the actual structural schematic of the circulating feeding system 44 in this embodiment, the circulating feeding system 44 includes a circulating feeding block 441, a feeding belt 442, and an elastic fixing ring 443; specifically, the circulating feeding block 441 is fixedly installed on the upper side of the crushing box 11, the feeding belt 442 is rotatably installed on the circulating feeding block 441, and the feeding belt 442 is rotated by a motor. That is, driven by the motor, the feeding belt 442 can continuously rotate.

[0038] The elastic fixing rings 443 are installed equidistantly and successively on the feeding belt 442, and an installation through hole 4431 for limiting and installing the lithium battery is opened on the elastic fixing ring 443. A number of installation holes 4421 for installing the elastic fixing rings 443 are opened on the feeding belt 442. In this embodiment, the elastic fixing ring 443 is made of rubber material and has the properties of contraction and elasticity. During actual operation, the lithium batteries are inserted one by one into the installation holes 4421 of the elastic fixing rings 443. Due to the characteristics of the elastic fixing rings 443, they can automatically contract to fix the lithium batteries on the installation holes 4421. Then, with the circulating rotation of the feeding belt 442, the lithium batteries are transferred to the position of the feeding hole 111 for the next step of breaking and material taking operations.

[0039] Referring to Figure 5 and6 As shown in the figure, it is a schematic structure of the fixing device 45 in this embodiment. Specifically, the fixing device 45 in this embodiment includes a driving cylinder 451, an abutting plate 452, an abutting compression spring 453, a tightening rod 454, and an arc-shaped tightening block 455; the driving cylinder 451 is fixedly installed on the lower side of the circulating feeding block 441 and extends downward. The abutting plate 452 is slidably installed on the installation groove 411, and a through hole 4521 for the material-breaking drill bit 43 to pass through is opened on the abutting plate 452. The abutting compression spring 453 is installed between the lower side of the abutting plate 452 and the bottom of the installation groove 411 to drive the abutting plate 452 to always have a tendency to move upward. The tightening rod 454 is sequentially rotatably installed on the side wall of the abutting plate 452. A through groove 412 for the tightening rod 454 to pass through is opened on the fixing block 41. A sliding rod 4541 is integrally provided on the side wall of the tightening rod 454. A sliding groove 413 communicating with the through groove 412 and for the sliding rod 4541 to slide downward is opened on the side wall of the through groove 412. The arc-shaped tightening block 455 is fixedly installed at the upper end of the tightening rod 454 to fix the lithium battery shell.

[0040] During the actual operation process, the lithium batteries are sequentially fixed through the elastic fixing rings 443 on the feeding belt 442, and then transported to the position of the feeding hole 111 according to the feeding belt 442 and stopped. At the same time, the driving cylinder 451 is started, and the driving cylinder 451 drives the lithium battery to move from the feeding hole 111 into the installation groove 411. After entering the installation groove 411, the driving motor 42 drives the material-breaking drill bit 43 to start running to perform drilling and crushing operations on the battery; during the process of crushing the lithium battery by the drill bit, the lithium battery squeezes the abutting plate 452, causing the abutting plate 452 to move downward, and synchronously driving the upper part of the tightening rod 454 to gather inward, so that the lithium battery shell can be fixed by the arc-shaped tightening block 455 to improve the actual crushing and drilling effect. It should be noted that the tightening rod 454 in this embodiment is made of metal material and is not easily broken even under a certain elastic deformation. After the drilling operation is completed, the suction cylinder 31 sucks out the materials inside the lithium battery outward, and the whole operation is carried out in a closed environment. The cylinder rises, and the resilience of the abutting compression spring 453 drives the lithium battery shell to rise.

[0041] Continue to refer to Figure 6 As shown in the figure, in order to be able to take out the lithium battery shell more smoothly after the material is extracted, a fixed suction cup 4511 for adsorbing and fixing the lithium battery is installed at the bottom of the driving cylinder 451, that is, after the material is broken and taken out, the driving cylinder 451 rises, and at the same time the fixed suction cup 4511 is opened to ensure that the lithium battery shell is smoothly lifted upward. After the lithium battery is lifted to the initial position, the feeding belt 442 transports the lithium battery shell away. By repeating this process, the recycling operation of the lithium battery is realized.

[0042] In addition, a limiting groove 4411 for sliding and limiting the lithium battery shell is provided on the circulating feeding block 441. The setting of the limiting groove 4411 enables the battery shell to move more stably on the fixed block 41, and its path is not easily misaligned, achieving the actual processing effect.

[0043] Refer to Figure 3 , 7 As shown in the figure, when extracting materials through the suction cylinder 31 after drilling and crushing the lithium battery, it is difficult to completely extract all the materials inside the lithium battery. Therefore, a vibration device 5 is provided between the abutting plate 452 and the installation groove 411; specifically, the vibration device 5 includes a vibration compression spring 51 and a vibration block 52. The vibration compression spring 51 is sequentially installed on the side wall of the feeding hole 111. A number of embedding holes 53 corresponding to the vibration compression spring 51 are provided on the side wall of the feeding hole 111. The vibration block 52 is fixedly installed at the extending end of the vibration compression spring 51. An arc-shaped guide surface is provided on the vibration block 52. And a rubber sealing ring 112 is fixedly installed above the feeding hole 111. A sealing hole 113 for inserting and sliding the lithium battery shell is provided in the middle of the rubber sealing ring 112.

[0044] During the actual operation process, when the lithium battery shell is lifted upward after being broken, the shell will contact the vibration block 52. The vibration blocks 52 are symmetrically arranged on the left and right and are all connected by the vibration compression spring 51, and the resilience of the vibration compression spring 51 is the same. Therefore, when the battery shell rises, the number of vibration blocks 52 in contact with the battery shell on the left and right sides will change. When the number of vibration blocks 52 in contact with the battery shell on the left side is more, the battery shell will be pushed to the right. Similarly, when the number on the right side is more, the battery will be pushed to the left, thus realizing the effect of swinging left and right during the rising process of the battery.

[0045] Refer to Figure 8 , 9 As shown in the figure, further, in order to ensure that the operation can be carried out quickly during the actual operation, that is, in order to achieve automatic and rapid feeding of the battery, in this embodiment, a feeding device 6 is provided on the circulating feeding block 441; specifically, in this embodiment, the feeding device 6 includes a linkage block 61, a loading guide groove 62, a feeding compression spring 63, and a lower pressing plate 64; the linkage block 61 is connected to the driving cylinder 451 and extends upward. The loading guide groove 62 is fixedly installed on the circulating feeding block 441 and extends toward the feeding belt 442 on the upper side. One end of the feeding compression spring 63 is installed on the side wall of the loading guide groove 62, and the other end abuts against the lithium battery shell. A feeding hole 65 corresponding to the installation hole 4421 is provided below the loading guide groove 62. The lower pressing plate 64 is fixedly connected to the linkage block 61 to punch and extrude the lithium battery shell from the feeding hole 65 into the installation hole 4421.

[0046] During specific operation, by driving the cylinder 451 to press the lithium battery casing downward, the linkage block 61 can be driven to move synchronously, and then the lower pressure plate 64 can be driven to move the new unbroken lithium battery downward, and enter the installation hole 4421 from the loading hole 65, thereby realizing automatic and synchronous loading and accelerating the actual operation efficiency.

[0047] Last reference Figure 10 Furthermore, in order to enable the crushed lithium battery to fall quickly and be automatically taken out, an inclined discharge block 66 is provided on the side wall of the circulating feed block 441, and an elastic discharge plate 67 is provided at the protruding end of the inclined discharge block 66. When the battery is crushed, the crushed empty battery shell will run with the feeding belt 442 until it reaches the position of the inclined discharge block 66. The inclined surface of the inclined discharge block 66 will drive the lithium battery shell to detach from the mounting hole 4421, and the resilience of the elastic discharge plate 67 drives the lithium battery shell to completely detach from the mounting hole 4421, ensuring that the automation of the device is more stable.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
