In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] Example:

[0028] Please refer to the attached Figure 1-8 ,This scheme proposes a waste lithium battery crushing and sorting machine for crushing the waste lithium batteries and separating the electrode materials, metal materials and electrolyte in the components of the lithium batteries and collecting them independently.

[0029] Specifically, a crushing mechanism is installed inside the sorting box 1, and the crushing mechanism includes a crushing box 2 arranged inside the sorting box 1. A feeding hopper 5 is provided on the crushing box 2, and the feeding hopper 5 penetrates to the outside of the sorting box 1. Waste lithium batteries can be put into the crushing box 2 through the feeding hopper 5, so that the crushing roller 3 installed in the crushing box 2 can crush the waste lithium batteries.

[0030] A double-shaft motor 4 is installed on the sorting box 1 , and the output shaft of the double-shaft motor 4 and the crushing roller 3 are connected through a transmission member 7 .

[0031] After the waste lithium battery is put into the crushing box 2, the double-axis motor 4 is turned on to run, and the crushing roller 3 is driven to rotate through the transmission member 7, so that the crushing roller 3 crushes the waste lithium battery during the rotation process, thereby separating the various components of the waste lithium battery. At the same time, the lower surface of the crushing box 2 is provided with evenly distributed sieve holes A8. During the crushing process of the lithium battery, the electrode material and metal material that are crushed into small pieces will pass through the sieve holes A8, and the electrode material and metal material filtered by the sieve holes A8 will be retained in the crushing box 2, and will be repeatedly crushed during the continuous rotation of the crushing roller 3, thereby improving the crushing effect of the device on the lithium battery, so as to achieve a more detailed sorting of the electrode material and metal material in the lithium battery.

[0032] An impact plate 6 is installed on the inner wall of the crushing box 2, and the crushing roller 3 rotates counterclockwise in the crushing box 2. When the lithium battery is put into the crushing box 2 from the feeding hopper 5, it will fall on the surface of the crushing roller 3, and under the rotation of the crushing roller 3, the lithium battery will be hit to the surface of the impact plate 6, so that the lithium battery and the impact plate 6 are crushed for the second time, further increasing the crushing effect of the lithium battery in the crushing box 2.

[0033] A movable screen plate 9 is sleeved and installed on the surface of the crushing box 2. The surface of the movable screen plate 9 is provided with evenly distributed screen holes B10. The channel formed by the matching and alignment of the screen holes B10 and the screen holes A8 is a complete filter hole.

[0034] After the lithium battery inside the crushing box 2 is crushed, the electrode material and the metal material are filtered by the filter hole channel after the mesh A8 and the mesh B10 are aligned. The upper surface of the movable screen plate 9 is provided with an annular tooth 11, and a crank 12 is installed on the sorting box 1. One end of the crank 12 passes through the outside of the sorting box 1, and the other end of the crank 12 is located inside the sorting box 1 and is connected to a gear 13. The gear 13 is meshed with the annular tooth 11. The crank 12 can control the rotation of the gear 13, and then the gear 13 meshes with the annular tooth 11 to drive the movable screen plate 9 to rotate, thereby realizing the rotation adjustment of the movable screen plate 9 on the crushing box 2.

[0035] The filter hole channel formed by the misalignment between the sieve holes A8 and the sieve holes B10 can form filter hole channels of different sizes according to the overlapping area between the two sieve holes, so that the device can crush lithium batteries into blocks of different sizes, which is convenient for subsequent material sorting.

[0036] More specifically, a vibrating screen mechanism is installed inside the sorting box 1 below the crushing box 2 to separate the crushed materials from the waste, so as to facilitate the recycling of the crushed materials and the collection and treatment of the waste.

[0037] The vibrating screen mechanism includes a guide rod 14 installed inside the sorting box 1. The guide rods 14 are arranged in four numbers and are distributed in a rectangular shape. A spring A20 is sleeved on the outside of each guide rod 14. The collecting box 15 is slidably installed on the guide rod 14. At the same time, a vertically liftable screen 16 is arranged above the collecting box 15. The spring A20 is arranged below the screen 16. The screen 16 is lifted up by the elastic force of the spring A20.

[0038] When the lithium battery in the crushing box 2 is crushed, the crushed electrode material, metal material and waste generated in the crushing process will fall on the surface of the screen 16. The large pieces of material filtered out will be retained on the surface of the screen 16, and the waste will fall into the vibration motor 17 and be collected. The lower surface of the collection box 15 is equipped with a vibration motor 17. By turning on the vibration motor 17, the collection box 15 and the screen 16 vibrate, and the electrode material, metal material and waste on the surface of the screen 16 are further vibrated and screened, so that the materials and waste are fully separated.

[0039] A magnetic separation mechanism is rotatably installed inside the separation box 1 to separate the electrode material and the metal material on the surface of the screen 16 to collect the metal material.

[0040] The magnetic separation mechanism includes a mounting shaft 18 installed in the separation box 1. An eccentric wheel 19 is arranged on the mounting shaft 18. The eccentric wheel 19 is located below the screen 16. The screen 16 will contact the upper surface of the eccentric wheel 19 under the action of gravity.

[0041] The mounting shaft 18 is in transmission connection with the transmission member 7. When the dual-shaft motor 4 drives the crushing roller 3 to rotate during the crushing process, the mounting shaft 18 will be synchronously driven to drive the eccentric wheel 19 to rotate, and the eccentric wheel 19 will further push the collection box 15 to slide up and down along the surface of the guide rod 14 during the rotation process. When the collection box 15 is in the process of sliding up, the screen 16 will be pushed up synchronously through the spring A20.

[0042] A guide plate 21 is provided inside the sorting box 1, and a mounting groove is provided below the guide plate 21, and a magnetic block 22 is installed in the mounting groove. When the screen 16 is in the process of rising, the metal material on the surface of the screen 16 will contact the surface of the magnetic block 22 and be adsorbed and fixed by the magnetic block 22. Further, after the screen 16 slides down, the metal material will be retained on the surface of the magnetic block 22, and the electrode material will be retained on the surface of the screen 16, and will slide down with the screen 16, finally realizing the separation of the electrode material and the metal material.

[0043] The guide plates 21 are arranged in a plurality of groups and are linearly distributed at equal distances, and gaps are left between the guide plates 21. The cross-section of the guide plates 21 in the vertical direction is triangular, and the bottom surface thereof is parallel to the screen 16, so that the electrode materials, metal materials, and waste chips crushed in the crushing box 2 will fall to the surface of the screen 16 under the guiding effect of the guide plates 21 during the falling process, and the metal materials will not be able to contact the magnetic blocks 22, thereby preventing the metal materials from adhering to the magnetic blocks 22 and causing blockage in the gaps.

[0044] Specifically, two groups of symmetrically distributed slots 38 are provided on the sorting box 1 , and the upper edges of the slots 38 are flush with the lower surface of the magnetic block 22 .

[0045] The sorting box 1 is provided with a discharge mechanism for pushing the metal materials adsorbed on the magnetic block 22 out of the sorting box 1 to realize the collection of the metal materials after sorting.

[0046] The material discharging mechanism comprises a slide rail seat 23 installed around the slot 38 on the outer surface of the sorting box 1 , a shovel plate 24 is slidably installed in the slide rail seat 23 , and the shovel plate 24 is adapted to the slot 38 on the surface of the sorting box 1 .

[0047] A turntable 25 is mounted on the other output shaft of the dual-axis motor 4, and a connecting rod 26 is hingedly mounted on the non-center of the surface of the turntable 25, and the other end of the connecting rod 26 is rotatably connected to the shovel plate 24. When the dual-axis motor 4 drives the crushing mechanism and the vibrating screen mechanism to operate, the turntable 25 is synchronously driven to rotate, and the connecting rod 26 is driven to rotate through the turntable 25, and the shovel plate 24 is further controlled to slide in the slide rail seat 23.

[0048] When the shovel plate 24 is sliding, it will penetrate the slot 38 on the surface of the sorting box 1 and insert into the inside of the sorting box 1, and further make the shovel plate 24 contact the surface of the magnetic block 22, and push the metal material on the surface of the magnetic block 22 back to the other side slot 38. The surface of the sorting box 1 is installed with a receiving plate 27 located below the other side slot 38, and the metal material pushed out from the other side slot 38 will fall on the surface of the receiving plate 27, thereby realizing the separation of the metal material from the crushed material.

[0049] And during the sliding process of the shovel plate 24 and the screen 16, when the screen 16 is at the uppermost position and starts to slide downward, the shovel plate 24 is located outside the sorting box 1 and starts to be inserted into the sorting box 1. When the screen 16 slides to the bottom, the shovel plate 24 is just inserted to the maximum depth inside the sorting box 1, and all the metal materials adsorbed and fixed on the surface of the magnetic block 22 can be pushed out.

[0050] At this time, the electrode material, metal material and waste filtered will fall on the surface of the shovel plate 24, and fall back to the surface of the screen 16 during the resetting process of the shovel plate 24. During the second sliding process of the screen 16, the crushed material and waste are separated by vibration screening.

[0051] The sorting box 1 is also provided with a waste collecting mechanism for recovering the waste generated after crushing. The waste collecting mechanism comprises a negative pressure fan 29 arranged on the surface of the sorting box 1, and a dust suction pipe 28 is arranged on the receiving plate 27 and is connected to the inside of the sorting box 1.

[0052] When the screen 16 slides to the bottom, the dust suction pipe 28 is located above the screen 16. At this time, when the screen 16 vibrates and screens the electrode materials, metal materials, and waste chips, the negative pressure fan 29 is operated to suck in the waste chips on the surface of the screen 16 to collect the waste chips. It can also suck in the waste gas generated during the damage of the lithium battery to avoid pollution caused by the discharge of the waste gas.

[0053] When the screen 16 slides to the top, the electrode material and metal material on the surface of the screen 16 will contact the bottom of the magnetic block 22, thereby overcoming the elastic force of the spring A20 and inserting into the interior of the vibration motor 17, reducing the distance between the screen 16 and the vibration motor 17, so that the magnetic block 22 can absorb the metal scraps in the vibration motor 17, and fully separate and collect the metal materials. At this time, the dust suction pipe 28 will be aligned with the vibration motor 17, further realizing the suction and collection of the electrode scraps in the vibration motor 17.

[0054] It is worth noting that a waste liquid collection mechanism is also provided inside the sorting box 1 for collecting the electrolyte generated during the crushing process of the lithium battery.

[0055] The waste liquid collection mechanism includes a waste liquid tank 31 installed at the lower part of the sorting box 1, and a collecting pipe 30 is installed on the waste liquid tank 31. The collecting pipe 30 is arranged in a T shape, wherein the upper end of the collecting pipe 30 is connected to a connecting hose 37, and the other end of the connecting hose 37 is connected to the collecting box 15, and the lower end of the collecting pipe 30 is connected to the waste liquid tank 31, and a one-way valve 32 is installed at the connection between the collecting pipe 30 and the connecting hose 37 and the waste liquid tank 31.

[0056] When the lithium battery is damaged, the generated electrolyte will flow to the surface of the collection box 15. A filter element is arranged inside the connecting hose 37 to prevent the entry of waste chips, so that the electrolyte can enter and be blocked by the one-way valve 32. A pressure rod 34 is inserted inside the other end of the collection tube 30. The pressure rod 34 is horizontally distributed and passes through the outside of the sorting box 1. A piston block 33 is installed at one end of the pressure rod 34 inserted in the collection tube 30, and a spring B36 is sleeved on the outside of the piston block 33. The piston block 33 is always pulled to the outside of the collection tube 30 under the action of the spring B36.

[0057] The surface of the rotating disk 25 is connected with a vortex block 35, and the pressure rod 34 always contacts the surface of the vortex block 35 under the elastic force of the spring B36. When the rotating disk 25 rotates, the vortex block 35 is driven to rotate, and the pressure rod 34 is further caused to slide back and forth in the collection tube 30 under the thrust of the vortex block 35, so that the piston block 33 moves in the collection tube 30. When the piston block 33 is pulled outward in the collection tube 30, negative pressure is formed, and the electrolyte in the connecting hose 37 is drawn into the collection tube 30. When the piston block 33 is squeezed inward in the collection tube 30, the electrolyte in the collection tube 30 is injected into the waste liquid tank 31, so as to further realize the separation and collection of the electrolyte.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
