Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery regeneration, and in particular relates to a device for regenerating electrode materials of waste lithium batteries. Background Art

[0002] Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solutions. The recycling of waste lithium batteries is a multi-stage process, in which the recycled lithium batteries are first fully discharged and then transported to the shredder.

[0003] Most of the shredders used in the waste lithium battery electrode material recycling devices in the prior art directly shred the lithium batteries that have been soaked in salt water. Since a certain amount of moisture will remain on the surface of the lithium batteries after being soaked in salt water, long-term direct batch processing of lithium batteries with residual salt water on the surface is easy to corrode the pulverizing rollers inside the shredder, thereby reducing the service life of the shredder, which is not conducive to use.

[0023] See also Figure 1-6The utility model provides a waste lithium battery electrode material recycling device, comprising a crushing box 1, a drying cylinder 2 is arranged on the top of the crushing box 1, a discharge port 18 is connected and fixed at the middle position between the crushing box 1 and the drying cylinder 2, a sealing valve 19 is installed inside the discharge port 18, a rotating cylinder 13 is rotatably connected through the middle position of the top surface of the drying cylinder 2, the bottom of the rotating cylinder 13 extends to the inner cavity position of the drying cylinder 2, a rotating plate 4 is fixedly sleeved at the outer circumference of the rotating cylinder 13 located at the top of the inner cavity of the drying cylinder 2, and movable shafts 5 symmetrically distributed are rotatably connected on both sides of the bottom surface of the rotating plate 4, a gear ring 9 is fixed on the top of the inner circumference of the drying cylinder 2, and the outer circumference of the movable shaft 5 close to the outer circumference of the gear ring 9 is fixedly sleeved A first gear 8 is provided, and the first gear 8 is meshedly connected with a gear ring 9. A plurality of stirring rods 6 are evenly fixed on both sides of the bottom of the outer circumference of the movable shaft 5, and symmetrically distributed heating plates 7 are fixed on the upper and lower ends of the outer circumference of the stirring rods 6. Connecting pipes 22 are evenly fixed and connected on both sides of the outer circumference of the rotating cylinder 13, and a plurality of exhaust holes 23 are evenly opened on the upper and lower ends of the outer circumference of the connecting pipe 22. A filter screen 24 is fixed inside the exhaust hole 23. The lithium battery soaked in salt water is placed inside the drying cylinder 2, so that the heating plate 7 is fully in contact with it and is fully in contact with the drying effect of the hot air discharged from the connecting pipe 22 through the exhaust hole 23 during the circular motion, thereby being able to remove the residual moisture attached to the surface of the lithium battery.

[0024] Further as Figure 1 , Figure 3 and Figure 5 As shown, it is worth explaining in detail that an air pipe 14 is provided on the top of the rotating drum 13, and a motor 3 is fixed at a position on the top of the drying drum 2 located on one side of the rotating drum 13. A second gear 12 is fixedly sleeved on the output end of the motor 3, and a third gear 15 is fixedly sleeved on the outer circumferential surface of the rotating drum 13. The second gear 12 and the third gear 15 are meshingly connected. A slot 16 is provided on the surface of the bottom of the air pipe 14, and a sealing ring 17 is slidably inserted inside the slot 16. The bottom of the sealing ring 17 passes through the slot 16 and is fixed to the surface of the top of the rotating drum 13. When the motor 3 is started, the second gear 12 is rotated, so that the rotating drum 13 can be rotated under the meshing action between the second gear 12 and the third gear 15. The collision support action of the slot 16 and the sealing ring 17 can limit the movement trajectory of the rotating drum 13 without affecting the air pipe 14. At the same time, the sealing ring 17 can seal the connection between the rotating drum 13 and the air pipe 14.

[0025] Further as Figure 3As shown, it is worth explaining in detail that a support ring groove 10 is opened at the position of the inner circumference of the drying cylinder 2 near the rotating plate 4, and limit blocks 11 are slidably inserted on both sides of the inner cavity of the support ring groove 10. The side of the limit blocks 11 close to each other passes through the support ring groove 10 and is fixed to the surface of one side of the rotating plate 4. When the rotating plate 4 rotates, the limit block 11 can be driven to fit the inner cavity of the support ring groove 10 to make a circular motion, so that the rotation state of the rotating plate 4 can be more stable under the interference support effect of the inner cavity of the support ring groove 10 and the surface of the limit block 11.

[0026] Further Figure 3 As shown, it is worth explaining in detail that a symmetrically distributed connecting plate 26 is fixed to the outer circumferential surface of the rotating cylinder 13 at the position of the bottom of the movable shaft 5 at an adjacent position, and an inclined scraper 25 is fixed to the bottom of the connecting plate 26. The surface of the bottom of the scraper 25 fits with the bottom of the inner cavity surface of the drying cylinder 2. The rotating cylinder 13 drives the scraper 25 and the connecting plate 26 to make a circular motion during the rotation of the rotating cylinder 13, thereby promoting the lithium battery placed at the bottom of the inner cavity of the drying cylinder 2, so that it is easy to fall into the discharge port 18 to avoid blockage.

[0027] This solution has the following working process: in actual use, when the user needs to dry the lithium battery entering the drying drum 2 to remove moisture attached to the surface, the gas pipe 14 is connected to the hot air delivery pipe and the heating plate 7 is turned on to heat it. After a period of time, the second gear 12 is rotated by starting the motor 3, so that the rotating drum 13 can rotate under the meshing action between the second gear 12 and the third gear 15, so that the connecting pipe 22 can make a circular motion and in this process, hot air can be discharged from the exhaust hole 23 through the connecting pipe 22, and the hot air is evenly transported to the position of the inner cavity of the drying drum 2 so that the hot air is fully in contact with the lithium battery, thereby ensuring the drying effect of the lithium battery, and preventing the lithium battery from extending to the filter 24. The inner cavity of the connecting tube 22 is blocked, and when the rotating plate 4 rotates, it can drive the two movable shafts 5 to make circular motion, so that the movable shaft 5 can rotate under the meshing action of the first gear 8 and the ring gear 9, so that the movable shaft 5 can rotate while making circular motion with the rotating plate 4, thereby driving the adjacent heating plate 7 to make a corresponding motion trajectory, so that the lithium battery entering the drying cylinder 2 can be fully in contact with the heating plate 7, thereby further improving the drying effect of the lithium battery, so that after the sealing valve 19 is opened, the surface of the lithium battery entering the crushing box 1 through the discharge port 18 will not be attached to the water, thereby avoiding the corrosion caused by the crushing roller inside the crushing box 1 being in long-term contact with the lithium battery with salt water attached to the surface.

[0028] According to the above working process, the lithium battery soaked in salt water is placed inside the drying drum 2, so that it is fully in contact with the heating plate 7 which is rotating with the movable shaft 5 while making circular motion, and is fully in contact with the drying effect of the hot air discharged from the connecting pipe 22 through the exhaust hole 23 during the circular motion, so as to remove the residual moisture attached to the surface of the lithium battery, thereby avoiding the corrosion caused by the long-term contact of the crushing roller inside the crushing box 1 with the lithium battery with salt water attached to the surface, thereby ensuring the service life of the crushing roller inside the crushing box 1 and improving the practicality of the device.

[0029] Further Figure 2 As shown, it is worth explaining in detail that two fixing columns 20 are fixed on both sides of the top of the inner cavity of the crushing box 1, and a buffer cloth 21 is fixed at the middle position of the two adjacent fixing columns 20. After the sealing valve 19 is opened, when a lithium battery falls from the sealing valve 19 to the inner cavity position of the crushing box 1, it contacts the buffer cloth 21, so that the impact force caused by the collision between the lithium battery and the crushing roller inside the crushing box 1 can be reduced under the elastic buffering effect of the buffer cloth 21.

[0030] In summary: the lithium battery soaked in salt water is placed inside the drying drum 2, so that it is in full contact with the heating plate 7 which is rotating with the movable shaft 5 while making circular motion, and is in full contact with the drying effect of the hot air discharged from the connecting pipe 22 through the exhaust hole 23 during the circular motion, so that the residual moisture attached to the surface of the lithium battery can be removed, so as to avoid the corrosion caused by the pulverizing roller inside the pulverizing box 1 due to long-term contact with the lithium battery with salt water attached to the surface, thereby ensuring the service life of the pulverizing roller inside the pulverizing box 1, thereby improving the practicality of the device, and after opening the sealing valve 19, when a lithium battery falls from the sealing valve 19 to the inner cavity position of the pulverizing box 1, it contacts the buffer cloth 21, so that under the elastic buffering effect of the buffer cloth 21, the impact force caused by the collision between the lithium battery and the pulverizing roller inside the pulverizing box 1 can be reduced.

[0031] The motor 3 and the sealing valve 19 can be purchased on the market. The motor 3 and the sealing valve 19 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
