Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, and in particular to a charged waste lithium battery recycling and crushing device. Background Art

[0002] Disposable lithium batteries cannot be recharged, so in order to prevent the internal substances of the batteries from polluting the environment, lithium batteries need to be recycled in a centralized manner, especially cylindrical batteries with large quantities and small volumes. After these batteries are crushed and recycled, the materials are re-produced in batches to achieve the purpose of industrial circular production. The most common method for crushing and recycling these batteries is industrial crushers, which mostly use crushing rollers to rotate and apply pressure to crush the lithium batteries.

[0003] The current crusher uses two rollers to rotate and drive the crushing teeth to squeeze the cylindrical batteries to achieve crushing. The crushing effect is not thorough enough. After a single crushing, the crushed waste needs to be dumped again for a second crushing, or additional crushing rollers need to be added to achieve multi-stage crushing operations, which makes the crushing work time-consuming and labor-intensive. In addition, during the crushing process of the charged lithium battery, the internal electrolyte and the crushed waste cannot be effectively separated, and the electrolyte becomes corrosive when it encounters air, resulting in corrosion of the surface components of the crusher, affecting the subsequent crushing effect.

[0004] Therefore, how to provide a charged waste lithium battery recycling and crushing device is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0011] Furthermore, the toothed belt pulley assembly is composed of four sets of pulleys and a single toothed belt. One side of the single set of pulleys is movably penetrated through the outer guard plate by an axial rod and is fixed to the crushing teeth. The toothed belt pulley assembly drives two sets of crushing rollers to rotate in opposite directions between two sets of inner guard plates through two sets of pulleys.

[0012] Furthermore, the pushing mechanism also includes an electric telescopic cylinder and a pushing frame, the output end of the electric telescopic cylinder is fixed to the top of the pushing frame, the surface of the pushing frame is slidably set on one side of the outer guard plate through a stabilizing slide rod, the bottom of the pushing frame is slidably set on the surface of the spline shaft through a sliding hole, the two sides of the spline teeth are fitted with the position of the sliding hole below the pushing frame through bearings, and the pushing frame drives the spline teeth to move laterally on the surface of the spline shaft through the electric telescopic cylinder.

[0013] Furthermore, a feeding mechanism is provided on the inner side of the protective shell, and the feeding mechanism includes a separation screen and two sets of connecting ends. There is a certain gap between the inner surface of the protective shell and the separation screen, and convex rings are provided on both sides of the inner surface of the protective shell close to the separation screen.

[0014] Furthermore, a gear ring is provided on the outer side of the connecting end, and three groups of transmission ratchets distributed in a ring array about the axis of the connecting end are meshed on the surface of the gear ring.

[0015] Furthermore, among the three groups of transmission ratchets, two groups of transmission ratchets are respectively fixedly connected to the flip teeth in the two groups of transmission mechanisms, and a single group of transmission ratchets is movable on the outer surface of the protective shell through a coupling limiter.

[0018] The beneficial effects of the present invention are:

[0019] The present invention sets a separation screen, and the two sides of the separation screen are connected to the transmission ratchet through the connecting ends, and can be directly transmitted to the motor. In this way, the separation screen rotates between the two groups of inner guard plates, and the crushed waste is driven by the internal convex plate to move again to the top of the two groups of crushing rollers and fall, thereby realizing multi-stage crushing operation and improving the crushing effect of lithium batteries.

[0020] The present invention provides a push-off mechanism. Under normal circumstances, the motor can directly drive the two groups of crushing rollers to rotate on the opposite sides of the inner guard plate through the meshing effect of the spline teeth and the crushing teeth and the transmission effect of the toothed belt pulley assembly to crush the lithium battery. The push-off mechanism can push the spline teeth to move on the surface of the spline shaft, causing the spline teeth to separate from the crushing teeth, while the spline teeth and the flipping teeth are still meshed. The actual output torque of the motor can be increased to drive the separation screen to rotate at high speed between the two groups of inner guard plates. Under the action of centrifugal force, the electrolyte can pass through the separation screen and be sprinkled on the inner surface of the protective shell, thereby realizing the separation operation of the waste material and the electrolyte. Conversely, the reverse driving of the push-off mechanism realizes the separation between the spline teeth and the flipping teeth. At this time, the output torque of the motor can directly act on the two groups of crushing rollers to increase the crushing torque.

[0021] The present invention sets up a conveyor belt assembly, and the actual setting position of the conveyor belt assembly is directly below the two sets of crushing rollers. During the normal crushing process, the convex plate drives the waste to pass through the crushing rollers for multiple times, and the waste crushed by the crushing rollers will first fall on the surface of the conveyor belt assembly, and then the moving conveyor belt assembly drives the waste to fall on the separation screen. In this way, when discharging the material, it is only necessary to reversely drive the conveyor belt assembly to drive the waste to be sent out from the conveyor belt assembly port. In this way, the establishment of the conveyor belt assembly can better achieve the waste discharging effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] refer to Figure 1-7, including a protective shell 2 fixed on the top of the base 1 by a bracket, outer guard plates 5 are fixed at both ends of the protective shell 2, and inner guard plates 7 are fixed on the opposite sides of the two groups of outer guard plates 5 through pillars; two groups of transmission mechanisms 4, the two groups of transmission mechanisms 4 are respectively arranged on the left and right sides of the base 1, and the two groups of transmission mechanisms 4 are distributed in opposite directions, and the transmission mechanisms 4 drive the two groups of crushing rollers 9 to rotate in opposite directions between the two groups of inner guard plates 7; a separation screen 81, the separation screen 81 has connection ends 83 fixedly connected on both sides, the connection ends 83 are rotatably arranged on the surface of the inner guard plate 7, the separation screen 81 is rotatably arranged on the inner side of the protective shell 2 through the connection ends 83, and the inner surface of the separation screen 81 is annularly provided with a plurality of groups of convex plates 82, and the connection ends 83 are transmission-connected to the transmission mechanism 4.

[0035] In this embodiment, the base 1, the protective shell 2, the outer protective plate 5 and the inner protective plate 7 can be regarded as a whole. Due to the different positions of the components, they need to be explained separately. The function of the outer protective plate 5 and the inner protective plate 7 is mainly to improve the sealing effect and prevent the outside air from rushing into the interior and causing contact with the electrolyte. The two groups of crushing rollers 9 are directly movably mounted on the opposite sides of the two groups of inner protective plates 7, and the transmission mechanism 4 is used to realize counter-rotation, so as to crush the lithium battery. The crushed lithium battery fragments fall on the separation screen 81, and the separation screen 81 is used to realize the separation and filtration between the fragments and the electrolyte. At the same time, the separation screen 81 is transmitted to the transmission mechanism 4 through the connecting end 83, so that the separation screen 81 rotates between the two groups of inner protective plates 7, thereby driving the fragments to move to a high place again through the convex plate 82 and fall down, and the two groups of crushing rollers 9 perform multi-stage crushing operations.

[0036] refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 The transmission mechanism 4 includes a motor 41 and a push-off mechanism 42. A spline shaft 43 is fixed to the output end of the motor 41. The surface of the spline shaft 43 is slidably sleeved with a spline tooth 44. The inner surface of the spline tooth 44 is provided with a spline shape matching the surface of the spline shaft 43. The spline tooth 44 is meshed with a flipping tooth 45. The flipping tooth 45 is in transmission connection with the connecting end 83. A crushing tooth 46 is also meshed on the side of the spline tooth 44 away from the flipping tooth 45. The flipping tooth 45 and the crushing tooth 46 are respectively meshed on the left and right sides of the spline tooth 44. One side of the crushing tooth 46 is in transmission connection with a toothed belt wheel assembly 47. The toothed belt wheel assembly 47 is movably arranged on the opposite sides of the outer guard plate 5 and the inner guard plate 7. One side of the two groups of crushing rollers 9 movably penetrates the inner guard plate 7 through the shaft sleeve and is in transmission connection with the toothed belt wheel assembly 47. The toothed belt pulley assembly 47 is composed of four sets of pulleys and a single toothed belt. One side of the single set of pulleys is movably penetrated through the outer guard plate 5 by an axial rod and is fixed to the crushing teeth 46. The toothed belt pulley assembly 47 drives the two sets of crushing rollers 9 to rotate in opposite directions between the two sets of inner guard plates 7 through two sets of pulleys.

[0037] In this embodiment, the motor 41 directly drives the spline teeth 44 to rotate through the spline shaft 43, and the spline teeth 44 are meshed with flipping teeth 45 and crushing teeth 46 on both sides. On the one hand, the crushing teeth 46 can drive the toothed belt pulley assembly 47 to move in a rotating state, and the toothed belt pulley assembly 47 directly drives the two groups of crushing rollers 9 to rotate and crush on the opposite sides of the inner guard plate 7 to achieve basic crushing work. On the other hand, the spline teeth 44 drive the flipping teeth 45 to rotate, and the flipping teeth 45 are connected to the feeding mechanism 8 by transmission, so that the separation screen 81 is driven to rotate, thereby achieving a reciprocating crushing operation.

[0038] refer to Figure 7 The pushing mechanism 42 also includes an electric telescopic cylinder 421 and a pushing frame 422. The output end of the electric telescopic cylinder 421 is fixed to the top of the pushing frame 422. The surface of the pushing frame 422 is slidably set on one side of the outer guard plate 5 through a stabilizing slide bar 423. The bottom of the pushing frame 422 is slidably set on the surface of the spline shaft 43 through a sliding hole. The two sides of the spline teeth 44 are fitted with the position of the sliding hole below the pushing frame 422 through bearings. The pushing frame 422 drives the spline teeth 44 to move horizontally on the surface of the spline shaft 43 through the electric telescopic cylinder 421.

[0039] In this embodiment, the movement effect of the electric telescopic cylinder 421 can directly drive the pushing frame 422 to perform stable lateral movement on the stable slide bar 423, and its lower part is movably fitted with the two sides of the spline teeth 44 through the sliding hole. The description of the sliding hole here will not affect the rotation effect of the spline shaft 43 and the spline teeth 44, and only provides a lateral thrust, which can be specifically achieved through the internal bearing ball. It will not be described in detail here. In this way, when the spline teeth 44 move on the surface of the spline shaft 43, they can engage or disengage with the flipping teeth 45 or the crushing teeth 46, thereby achieving a separate control effect.

[0040] refer to Figure 2-6 A feeding mechanism 8 is also provided inside the protective shell 2. The feeding mechanism 8 includes a separation screen 81 and two groups of connection ends 83. There is a certain gap between the inner surface of the protective shell 2 and the separation screen 81, and convex rings are provided on both sides of the inner surface of the protective shell 2 near the separation screen 81. A gear ring 84 is provided on the outer side of the connection end 83. Three groups of transmission ratchets 85 distributed in a ring array about the axis of the connection end 83 are meshed on the surface of the gear ring 84. Among the three groups of transmission ratchets 85, two groups of transmission ratchets 85 are respectively fixedly connected to the two groups of flipping teeth 45 in the transmission mechanism 4, and a single group of transmission ratchets 85 is movable on the outer surface of the protective shell 2 through the coupling limit.

[0041] In this embodiment, the separation screen 81 is stabilized by the connection of the connecting ends 83 on both sides. Specifically, it can be understood that the two sets of connecting ends 83 are connected by a connecting rod, and the separation screen 81 is fixed on the surface of the connecting rod. In this way, when the connecting end 83 rotates on the surface of the inner guard plate 7, the separation screen 81 can be effectively driven to rotate, and the inner surface of the separation screen 81 is fixedly connected with the convex plate 82, and the direction of the convex plate 82 is aligned with the axis of the separation screen 81. When the separation screen 81 is flipped, the convex plate 82 can move synchronously, driving the battery fragments to move to a high place and then fall between the crushing rollers 9 to achieve multi-stage crushing operation, and the connecting end 83 is meshed with the transmission ratchet 85 through the tooth ring 84 opened on the surface. The three sets of transmission ratchets 85 are used to assist the inner guard plate 7 and synchronously set up the connecting end 83. On the other hand, the meshing effect can directly realize the transmission between the motor 41 through the flipping teeth 45, thereby realizing rotation control.

[0042] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A hopper 6 is fixed on the surface of the outer guard plate 5 on one side of the protective shell 2, and a conveyor belt assembly 11 is aligned below the hopper 6. The two groups of inner guard plates 7 are fixed by a connecting plate, and the upper part of the inner guard plate 7 near the outer guard plate 5 is fixedly connected to the suction box 10. There are two groups of conveyor belt assemblies 11, and the two groups of conveyor belt assemblies 11 are respectively arranged at positions fixed by connecting plates below the two groups of inner guard plates 7. A through opening is opened at the position of the outer guard plate 5 near the conveyor belt assembly 11, and one side of the conveyor belt assembly 11 is located directly below the two groups of crushing rollers 9. The protective shell 2 is fixedly connected to the liquid outlet 3 below.

[0043] In this embodiment, the lower part of the two groups of inner guard plates 7 is the same as the outer guard plate 5, and a through opening is opened near the position of the conveyor belt assembly 11. The two groups of inner guard plates 7 are still fixed at this position by a connecting plate, so as to provide an installation position for the conveyor belt assembly 11. The two sides of the conveyor belt assembly 11 are respectively located on the inner side of the separation screen 81 and one side of the outer guard plate 5, so that the lithium batteries in the hopper 6 can fall on the conveyor belt assembly 11 and be sent to the inner side of the separation screen 81 by the conveyor belt assembly 11 in a moving state, so as to achieve crushing, and the conveyor belt assembly 11 is simultaneously in the two groups of crushing rollers 9. Directly below, the fragments and electrolyte crushed by the crushing roller 9 will first fall on the surface of the conveyor belt assembly 11, and then be transported by the conveyor belt assembly 11 to the inside of the separation screen 81, where the electrolyte can be scraped off by a scraper or other device, and most of the electrolyte is combined with the fragments, so it will not be elaborated on here. In this way, when discharging is required, the conveyor belt assembly 11 can be driven in reverse to drive the fragments out from the inside of the separation screen 81. At the same time, the establishment of the suction box 10 can suck the internal air or fill the interior with inert gas to reduce the contact between air and electrolyte.

[0044] Working principle: First, the suction box 10 on the upper side of the inner guard plate 7 is driven to fill the inner side of the separation screen 81 with inert gas, and then the lithium battery is thrown into the hopper 6 on the side of the outer guard plate 5. The lithium battery normally falls on the surface of the conveyor belt assembly 11. The conveyor belt assembly 11 is driven at this time, driving the lithium battery to move to the inner side of the separation screen 81 and fall inside the separation screen 81. At this time, the motor 41 in the transmission mechanism 4 drives the spline shaft 43 and the spline teeth 44 to rotate directly, and the spline teeth 44 are engaged with the flipping teeth 45 and the crushing teeth 46, so that the crushing teeth 46 rotate the belt The movable toothed belt pulley assembly 47 moves, and the toothed belt pulley assembly 47 is connected to the two groups of crushing rollers 9, so that the two groups of crushing rollers 9 rotate on the opposite sides of the two groups of inner guard plates 7. At the same time, the turning teeth 45 rotate to drive the transmission ratchet 85 in the feeding mechanism 8 to rotate, and the transmission ratchet 85 is meshed with the gear ring 84. At this time, the connecting end 83 rotates on the outer ends of the two groups of inner guard plates 7, driving the separation screen 81 to rotate. The convex plate 82 fixedly connected to the inner side of the separation screen 81 can now send the lithium battery belt to a high place and fall between the two groups of crushing rollers 9, and the crushing rollers 9 press and crush the crushed lithium battery. The fragments fall on the conveyor belt assembly 11 and are conveyed to the inner side of the separation screen 81 again. The separation screen 81 rotates to realize the cyclic crushing operation, and the electrolyte passes through the separation screen 81 and is collected through the liquid outlet 3 under the protective shell 2. After being crushed for a period of time, the electric telescopic cylinder 421 in the push-off mechanism 42 is driven, and the push frame 422 is forced to slide on the surface of the stable slide bar 423, and at the same time, the spline teeth 44 are pushed to move to one side. At this time, the spline teeth 44 are separated from the crushing teeth 46 and remain in mesh with the flipping teeth 45, so that the torque of the motor 41 can directly It has the effect of driving the separation screen 81 to rotate. The rotation speed of the separation screen 81 becomes faster at this time, and the fragments cannot fall from a high place. In this way, under the action of centrifugal force, the fragments and the electrolyte are separated and collected separately. On the contrary, the electric telescopic cylinder 421 drives the spline teeth 44 to move in the opposite direction, so as to increase the actual pressure of the crushing roller 9, which is suitable for lithium batteries that are not easy to crush. Finally, after the crushing is completed, the conveyor belt assembly 11 drives in the reverse direction to drive the fragments out of the inner side of the separation screen 81 and collects them in the collection box position on the base 1, thereby realizing the separation and collection operation of the fragments and the electrolyte.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
