Description

Technical Field

[0001] The invention belongs to the technical field of lithium battery recycling, in particular to a lithium battery recycling device. Background Art

[0002] Lithium batteries are the mainstream product used in contemporary batteries. Similarly, used lithium batteries also contain harmful substances. If they are directly discarded, they will harm the environment. Some harmful substances will also cause harm to the human body. When recycling used lithium batteries, you first need to discharge the lithium batteries to discharge the residual electricity inside, and then use a crusher to crush them. The crushed batteries will expose the black powder inside. This type of black powder is a mixture of battery positive electrode materials, and the black powder contains more heavy metals. Therefore, when recycling, this type of black powder needs to be sieved out and collected from the crushed lithium battery fragments.

[0003] A patent with publication number CN117753758A discloses a lithium battery dismantling device, which uses an intermittent cutting knife in conjunction with a guide groove to cut the lithium battery. Because the cutting knife is made of soft steel, after the cutting knife is lifted up by the extrusion bead, the packaging film and protective shell of the lithium battery are cut without piercing the lithium battery. Then, the rigid end face of the outside is rubbed, and the packaging film and protective shell are rubbed and torn off, thereby separating the inside and the outside, and improving the dismantling of the outside of the lithium battery. There are still some problems in the actual application of the above scheme. Usually, the discharged lithium batteries are directly put into the crusher, and then the lithium batteries are crushed by the crushing roller of the crusher. However, since the feeding port of the crusher is usually exposed and no protective plate or sealing plate is set, if there is residual power in the lithium battery that has not been discharged, it will be squeezed and crushed by the crushing roller, which will cause combustion and explosion, and the feeding port will splash out, posing a certain safety hazard to the operator. Moreover, a large number of lithium batteries are directly put into the crusher, which will not only affect the efficiency of crushing the lithium batteries, but also cause a large number of lithium batteries to squeeze each other and get stuck inside the crushing roller, resulting in the need for subsequent shutdown and cleaning.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1: Figures 1 to 8 As shown, a lithium battery recycling device according to an embodiment of the present invention comprises a recycling box 1, a material storage box 2 is fixedly connected to the upper end surface of the recycling box 1, and the inner wall of the material storage box 2 is arranged in a cone shape for guiding the lithium battery to be discharged, a feeding port 11 is provided at the bottom of the inner cavity of the material storage box 2, and an automatic feeding component is arranged in the inner cavity of the feeding port 11; The automatic feeding assembly includes two receiving grooves 20 provided on the inner wall of the feeding port 11, the inner cavity of the receiving groove 20 is slidably connected with a slide plate 21, and a stop block 26 is fixedly connected to one side of the lower end surface of the slide plate 21; Two guide blocks 29 are symmetrically fixed to the two walls of the inner cavity of the recycling box 1, and a crushing chamber 28 is arranged between the two guide blocks 29. Two crushing rollers 27 are rotatably connected in the crushing chamber 28, and the two crushing rollers 27 are meshed with each other for crushing and recycling waste lithium batteries.

[0022] Specifically, in the prior art, since the feed port of the crusher is usually exposed and no protective plate or sealing plate is provided, if the residual power of the lithium battery is not fully discharged, it will be crushed by the crushing roller, causing combustion and explosion, and the splashing of the feed port will cause certain safety hazards to the operator. Moreover, a large number of lithium batteries directly put into the crusher will not only affect the efficiency of crushing the lithium batteries, but also cause a large number of lithium batteries to squeeze each other and get stuck inside the crushing roller, resulting in the need to stop the machine for cleaning later. The present invention puts the discharged lithium batteries into the storage box 2, and then uses the stop block 26 to drive the slide plate 21 to slide in the inner cavity of the storage groove 20, and opens the feeding port 11 to make the lithium batteries in the storage box 2 fall between the two crushing rollers 27 in the inner cavity of the recovery box 1. The inner wall of the storage box 2 is set in a cone shape, so that the lithium batteries can be quickly guided for discharge, and the crushing rollers 27 are driven to rotate to crush the lithium batteries. The setting of the two guide blocks 29 can prevent the lithium batteries from falling into the bottom of the inner cavity of the recovery box 1 from both sides of the two crushing rollers 27 without being crushed. The slide plate 21 is controlled to slide in the inner cavity of the storage groove 20 by circulation, so that the lithium batteries can be discharged quantitatively. The reciprocating sliding of the slide plate 21 can seal the feeding port 11. After the lithium batteries are crushed by the crushing rollers 27, the slide plate 21 will open again to discharge the second batch of lithium batteries for crushing, so as to prevent the lithium batteries from burning and exploding after being crushed when the residual power is not discharged.

[0023] like Figure 4 and Figure 5 As shown, a fixed sliding column 22 is fixedly connected to the inner cavity of the storage groove 20, and a U-shaped slider 23 is slidably connected to the outside of the fixed sliding column 22. A second spring 24 is fixedly connected to one end of the U-shaped slider 23, and one end of the second spring 24 is fixedly connected to the inner wall of the storage groove 20. A support rod 25 is rotatably connected to the outside of the U-shaped slider 23, and one end of the support rod 25 is rotatably connected to the slide plate 21.

[0024] Specifically, when the device is crushing and recycling lithium batteries, the slide plate 21 is driven to slide in the inner cavity of the storage groove 20 by the stop block 26, and the slide plate 21 pushes the support rod 25 to drive the U-shaped slide plate 23 to slide outside the fixed slide column 22, and at the same time, the U-shaped slide plate 23 squeezes the second spring 24 to move away from each other, so that the slide plate 21 slides into the inner cavity of the storage groove 20, and the feeding port 11 is opened to allow the lithium batteries to fall between the crushing rollers 27. After the slide plate 21 slides to the bottom of the inner cavity of the storage groove 20, the second spring 24 will bounce up the U-shaped slide plate 23 and make the U-shaped slide plate 23 slide in The outside of the fixed sliding column 22 moves closer to each other, so that the U-shaped sliding block 23 pushes the support rod 25 to drive the sliding plate 21 to reset, thereby closing and sealing the feeding port 11 again, thereby preventing subsequent lithium batteries from falling into the recycling box 1, achieving quantitative unloading and discharge of lithium batteries, improving the uniformity and crushing efficiency of lithium battery crushing, and solving the problem of the existing lithium battery recycling device not having a quantitative unloading component at the feeding port, causing a large number of lithium batteries to fall between the crushing rollers at the same time, resulting in a large number of lithium batteries being squeezed against each other and stuck inside the crushing rollers, resulting in the need for subsequent shutdown for cleaning.

[0025] like Figure 1 and Figure 8 As shown, a DC motor 3 is installed on one side of the recycling box 1, and the output shaft end of the DC motor 3 is connected to the transmission component 4, and the transmission component 4 includes a transmission bevel gear 41 fixedly connected to the output shaft end of the DC motor 3, and the transmission bevel gear 41 is meshed with a driving bevel gear 45. The driving bevel gear 45 is fixedly connected to a rotating shaft 42, and the rotating shaft 42 is fixedly connected to two worms 43 on the outside, and the two worms 43 are meshed with a worm wheel 44, and the worm wheel 44 is fixed to the crushing roller 27.

[0026] like Figure 1 and Figure 8 As shown, a support block 5 is installed on one side of the recovery box 1, and a transmission shaft 6 is rotatably connected inside the support block 5. Both ends of the transmission shaft 6 are fixedly connected with driven bevel gears 7, and the driven bevel gear 7 is meshed and connected with the driving bevel gear 45.

[0027] like Figure 1 , Figure 6 and Figure 8 As shown, a screw rod 14 is rotatably connected to the inner cavity of the recovery box 1, and a sliding rod 15 is threadedly connected to the outer surface of the screw rod 14. One end of the screw rod 14 passes through the recovery box 1 and is fixedly connected to a first bevel gear 8. The first bevel gear 8 is meshedly connected to the driven bevel gear 7.

[0028] Specifically, when recycling and crushing lithium batteries, the DC motor 3 is started to drive the transmission bevel gear 41 to rotate, and the transmission bevel gear 41 is meshed with the transmission driving bevel gear 45 to rotate, and then the rotating shaft 42 is driven to rotate. During the rotation of the rotating shaft 42, the two worms 43 are driven to rotate, and the meshing transmission worm gear 44 is rotated, thereby driving the two crushing rollers 27 to rotate to crush the lithium batteries. In addition, during the rotation of the driving bevel gear 45, the meshing transmission driven bevel gear 7 is rotated, and then the transmission shaft 6 is driven to rotate. During the rotation of the transmission shaft 6, the driven bevel gear 7 is meshed with the transmission first bevel gear 8 to rotate, and the screw rod 14 is driven to rotate. Then, the screw rod 14 is threaded to drive the sliding rod 15, so that the sliding rod 15 slides in the inner cavity of the groove 34 to reciprocate. During the sliding process, the sliding rod 15 will move the stop block 26 to drive the slide plate 21 to move, so that the feeding port 11 can be intermittently opened during the reciprocating movement of the slide plate 15 to achieve quantitative feeding of lithium batteries, thereby improving the uniformity and crushing efficiency of lithium batteries.

[0029] Embodiment 2: Figure 3 and Figure 4 As shown, a semicircular screening cover 30 is fixedly connected to the lower end of the two guide blocks 29, and the semicircular screening cover 30 is used to screen the black powder in the crushed lithium battery. A rotating column 35 is rotatably connected to the inner cavity of the semicircular screening cover 30, and a fixed rod 33 is fixedly connected to the outside of the rotating column 35, and a threaded stirring frame 32 is fixedly connected to one end of the fixed rod 33.

[0030] Specifically, after the lithium battery is crushed by the crushing roller 27, the crushed lithium battery will fall into the inner cavity of the semicircular screening cover 30, and then the rotating column 35 is driven to rotate, and the rotating column 35 drives the fixed rod 33 to rotate, and at the same time drives the threaded stirring frame 32 to rotate, and then the threaded stirring frame 32 is used to stir the lithium battery fragments in the inner cavity of the semicircular screening cover 30, and then the black powder on the lithium battery fragments is screened and separated through the mesh of the semicircular screening cover 30, so as to achieve the separation of the black powder from the inside of the lithium battery fragments.

[0031] like Figure 3 and Figure 4 As shown, a servo motor 31 is installed on one side of the recovery box 1, and the output shaft of the servo motor 31 is fixedly connected to the rotating column 35, a groove 34 is opened between the two guide blocks 29, and both ends of the slide rod 15 are slidably connected in the inner cavity of the groove 34, and two cleaning brushes 19 are installed at the lower end of the slide rod 15, and the cleaning brush 19 is used to clean the crushing roller 27.

[0032] like Figure 3 , Figure 6 and Figure 7As shown, two T-shaped slots 16 are provided at the upper end of the slide rod 15 , a first spring 18 is fixedly connected to the bottom of the inner cavity of the two T-shaped slots 16 , a T-shaped slider 17 is fixedly connected to one end of the first spring 18 , and the T-shaped slider 17 is used to move the stop block 26 .

[0033] Specifically, when the screw rod 14 is used to thread the sliding rod 15 to reciprocate in the inner cavity of the groove 34, the sliding rod 15 will drive the T-shaped sliding block 17 to move synchronously, so that the T-shaped sliding block 17 abuts against the abutment 26 to push the sliding plate 21 into the inner cavity of the receiving groove 20. When the sliding plate 21 completely slides into the inner cavity of the receiving groove 20, the screw rod 14 threadedly drives the sliding rod 15 to continue to move, and the sliding rod 15 will drive the T-shaped sliding block 17 to continue to abut against the abutment 26, so that the T-shaped sliding block 17 is forced to squeeze the first spring 18 to slide into the inner cavity of the T-shaped sliding groove 16, so that the T-shaped sliding block 17 is disengaged from the abutment 26, and then the second spring 24 will bounce the U-shaped sliding block 23, and make the U-shaped sliding block 23 slide on the outside of the fixed sliding column 22 and move closer to each other. The U-shaped slider 23 pushes the support rod 25 to drive the slide plate 21 to reset, thereby closing and sealing the feeding port 11 again, thereby preventing subsequent lithium batteries from falling into the recycling box 1, and realizing quantitative unloading and discharge of lithium batteries. During the reciprocating movement of the threaded transmission slide rod 15 of the screw rod 14, the slide rod 15 will also drive the cleaning brush 19 to move synchronously, thereby realizing the cleaning of the black powder sticking to the surface of the crushing roller 27, thereby solving the problem that a small amount of black powder sticks to the surface of the crushing roller when the crushing roller crushes the lithium battery in the existing lithium battery recycling device, so the crusher is usually stopped from time to time, and then the sticky black powder is cleaned on the surface of the crushing roller, thereby reducing the efficiency of lithium battery recycling and crushing.

[0034] like Figures 2 to 4 As shown, a discharge port 36 is opened on one side of the recycling box 1, a guide plate 12 is installed on one side of the recycling box 1 below the discharge port 36, a hinge is installed on one side of the recycling box 1, a sealing cover plate 13 is installed at one end of the hinge, a counterweight block is arranged inside the sealing cover plate 13, and the sealing cover plate 13 is used to block the discharge port 36.

[0035] like Figure 1 and Figure 4 As shown, a drawer 9 is slidably connected to one side of the recycling box 1, a handle groove 10 is provided on one side of the drawer 9, and an electric heater is arranged inside the lower end surface of the recycling box 1.

[0036] Specifically, after the lithium battery is crushed by the crushing roller 27, the crushed lithium battery will fall into the inner cavity of the semicircular screening cover 30, and then the servo motor 31 is started to drive the rotating column 35 to rotate, and the rotating column 35 drives the fixed rod 33 to rotate, and at the same time drives the threaded stirring frame 32 to rotate, and then the threaded stirring frame 32 is used to stir the lithium battery fragments in the inner cavity of the semicircular screening cover 30, and then the black powder on the lithium battery fragments is screened and separated through the mesh of the semicircular screening cover 30, so that the black powder is screened out and separated from the inside of the lithium battery fragments, and the screened and separated black powder will fall into the drawer 9 for collection, and then the electric heater is started to heat the drawer 9, and the internal moisture of the black powder in the drawer 9 is evaporated, thereby improving the recycling efficiency.

[0037] The working principle is as follows: the discharged lithium battery is put into the storage box 2, and then the stop block 26 is used to drive the slide plate 21 to slide in the inner cavity of the storage tank 20, and the feeding port 11 is opened to make the lithium battery in the storage box 2 fall between the two crushing rollers 27 in the inner cavity of the recovery box 1. The inner wall of the storage box 2 is conical, so that the lithium battery can be quickly guided for feeding, and the crushing rollers 27 are driven to rotate to crush the lithium battery. The setting of the two guide blocks 29 can prevent the lithium battery from falling into the bottom of the inner cavity of the recovery box 1 from both sides of the two crushing rollers 27 without being crushed. The slide plate 21 is controlled to slide in the inner cavity of the storage tank 20 by circulation, so that the lithium battery can be discharged quantitatively. The reciprocating sliding of the slide plate 21 can seal the feeding port 11 to prevent the lithium battery from burning and exploding after being crushed when the residual power is not completely discharged. When recycling and crushing lithium batteries, the DC motor 3 is started to drive the transmission bevel gear 41 to rotate, and the transmission bevel gear 41 is meshed with the transmission driving bevel gear 45 to rotate, and then the rotating shaft 42 is driven to rotate. During the rotation of the rotating shaft 42, the two worms 43 are driven to rotate, and the meshing transmission worm gear 44 is rotated, thereby driving the two crushing rollers 27 to rotate to crush the lithium batteries. In addition, during the rotation of the driving bevel gear 45, the meshing transmission driven bevel gear 7 is rotated, and then the transmission shaft 6 is driven to rotate. During the rotation of the transmission shaft 6, the driven bevel gear 7 is meshed with the transmission first bevel gear 8 to rotate, and the screw rod 14 is driven to rotate. Then, the screw rod 14 is used to thread the sliding rod 15, so that the sliding rod 15 slides in the inner cavity of the groove 34 to reciprocate. During the sliding process, the sliding rod 15 will move the stop block 26 to drive the slide plate 21 to move, so that the feeding port 11 can be intermittently opened during the reciprocating movement of the slide plate 15 to realize quantitative unloading of lithium batteries. When the screw rod 14 is used to thread the sliding rod 15 to reciprocate in the inner cavity of the groove 34, the sliding rod 15 will drive the T-shaped sliding block 17 to move synchronously, so that the T-shaped sliding block 17 abuts against the abutment 26 to push the sliding plate 21 into the inner cavity of the storage groove 20. When the sliding plate 21 completely slides into the inner cavity of the storage groove 20, the screw rod 14 threadedly drives the sliding rod 15 to continue to move, and the sliding rod 15 will drive the T-shaped sliding block 17 to continue to abut against the abutment 26, so that the T-shaped sliding block 17 is forced to squeeze the first spring 18 to slide into the inner cavity of the T-shaped sliding groove 16, so that the T-shaped sliding block 17 is separated from the abutment 26. The second spring 24 will then bounce up the U-shaped slider 23 and make the U-shaped slider 23 slide on the outside of the fixed slide column 22 and move closer to each other, so that the U-shaped slider 23 pushes the support rod 25 to drive the slide plate 21 to reset, thereby closing and sealing the feeding port 11 again, thereby preventing subsequent lithium batteries from falling into the recycling box 1, and realizing quantitative unloading and discharge of lithium batteries. During the reciprocating movement of the threaded transmission slide rod 15 of the screw rod 14, the slide rod 15 will also drive the cleaning brush 19 to move synchronously, thereby realizing the cleaning of the black powder sticking to the surface of the crushing roller 27.
