Below the lower box body 8, a discharging component 7 is installed. On the support plate 1 and outside the lower box body 8, a grading and filtering device 5 is installed. Below the support plate 1, a lifting and vibrating device 6 is provided.

[0023] Specifically, the grading and filtering device 5 includes a separation box 51, an upper filter screen 52, a lower filter screen 53, a sealing block 54, a threaded block 55, a connecting frame 56, a reduction motor 57, a lead screw 58 and a moving frame 59. The separation box 51 is installed on the support plate 1 at a position on one side of the lower box body 8. The upper filter screen 52 is installed inside the separation box 51. The lower filter screen 53 is installed inside the separation box 51 at a position below the upper filter screen 52. The sealing block 54 is installed at the bottom of the separation box 51 by means of threading. Two threaded blocks 55 are installed at one side of the separation box 51 away from the lower box body 8 by means of threading. The connecting frame 56 is installed at one side of the separation box 51 away from the lower box body 8 and above the two threaded blocks 55. One side of the top of the connecting frame 56 is installed with the reduction motor 57. The lead screw 58 is installed on one side of the reduction motor 57 close to the connecting frame 56. The moving frame 59 is installed above the upper box body 3, on one side of the two feeding assemblies 4 and outside the lead screw 58.

[0024] By adopting the above technical solution, the device can move the upper box body 3 and other structures onto the separation box 51 through the cooperation of structures such as the reduction motor 57 and the lead screw 58 when needed, and then grade the screened lithium manganese oxide cathode material through the upper filter screen 52 and the lower filter screen 53, thus better meeting the working requirements.

[0025] Specifically, the height of the outer bottom surface of the upper box body 3 is equal to the height of the outer top surface of the separation box 51, and the height of the inner top surface of the moving frame 59 is equal to the height of the outer top surface of the connecting frame 56.

[0026] By adopting the above technical solution, it is ensured that there is no gap between the upper box body 3 and the separation box 51 during the cooperation work, and the phenomenon that the moving frame 59 rotates and deviates during movement is prevented, thus ensuring the normal progress of the work.

[0027] When this embodiment is in use, when it is necessary to use the device to screen the lithium manganese oxide cathode material, if it is not necessary to classify the lithium manganese oxide cathode material, the upper box body 3 stays on the lower box body 8.

The lead screw 58 is threadedly connected to the moving frame 59, and the inner top surface of the moving frame 59 is closely attached to the outer top surface of the connecting frame 56. Therefore, the lead screw 58 drives the moving frame 59 and the upper box body 3 and other structures to move until the upper box body 3 and other structures move above the separation box 51. Then, the material is fed into the upper box body 3 through the two feeding assemblies 4, and the screening assembly 2 is manipulated to screen it. If the upper box body 3 is above the lower box body 8, the screened lithium manganese oxide cathode material falls into the lower box body 8 and is then discharged through the discharging assembly 7. If the upper box body 3 is above the separation box 51, the screened lithium manganese oxide cathode material falls into the separation box 51 and is then classified and filtered by the upper filter screen 52 and the lower filter screen 53. The classified materials respectively fall on the upper filter screen 52, the lower filter screen 53 and the inner bottom of the separation box 51. Then, the staff unscrews the sealing block 54 and the two threaded blocks 55 to take out the materials at each position respectively, and the work is completed.

A bottom plate 61 is arranged below the discharging assembly 7, a connecting plate 65 is arranged between the bottom plate 61 and the discharging assembly 7, and two electric telescopic rods 63 are installed between the connecting plate 65 and the support plate 1.

[0030] By adopting the above technical solution, the device can adjust the height of the lower box body 8 and other structures through the electric telescopic rod 63 when needed, so as to better meet the working needs in different situations.

[0031] Specifically, the lifting and vibrating device 6 further includes a vibrator 64, and a plurality of vibrators 64 are installed above the connecting plate 65 and between the two electric telescopic rods 63.

[0032] By adopting the above technical solution, the device can drive the lower box body 8 and other structures to vibrate through the vibrator 64 when needed, so as to prevent the lithium manganese oxide cathode material from staying at a certain position during the working process.

An elastic rubber frame 66 is installed between the bottom plate 61 and the connecting plate 65, and a plurality of dampers 62 are installed between the bottom plate 61 and the connecting plate 65 and inside the elastic rubber frame 66.

[0034] By adopting the above technical solution, the device can buffer the vibration generated by the vibrator 64 through the damper 62 and the elastic rubber frame 66, thereby reducing the possibility of the vibration affecting the surrounding environment and personnel.

[0035] During the use of this embodiment, when it is necessary to adjust the height of structures such as the lower box body 8, the staff can start the two electric telescopic rods 63 in the lifting vibration device 6, so as to drive the support plate 1 and the structures thereon to move up and down, thereby adjusting the height of structures such as the lower box body 8. When it is necessary to prevent the lithium manganate cathode material from staying at a certain position during the working process, start each vibrator 64 to drive structures such as the connecting plate 65 and the support plate 1 to vibrate, and then drive structures such as the lower box body 8 to vibrate, thereby preventing the lithium manganate cathode material from staying at a certain position during the working process. The damper 62 and the elastic rubber frame 66 between the connecting plate 65 and the bottom plate 61 can buffer the vibration.

The lithium-ion battery cathode materials with large volume and large weight enter the feeding channel under the action of centrifugal force and enter the recycling device through the feeding channel, and the qualified lithium-ion battery cathode materials enter the bottom of the box body through the leakage holes of the filter sieve plate; when the rotating shaft rotates, it will drive the gear A to rotate, the gear A drives the gear B to rotate, the gear B drives the rotating rod to rotate, the rotating rod drives the vibrating wheel to rotate, and the vibrating wheel makes the filter sieve plate vibrate up and down through the contact block to filter and screen the lithium-ion battery cathode material.

[0037] In the present utility model, the structure and principle of the damper 62 have been disclosed in a washing machine shock absorption device for smart home with the Chinese patent application number 201721446985.6. Its working principle is composed of a piston and a fuel tank, and its interior is filled with hydraulic oil.

[0038] The structure and principle of the vibrator 64 in the present utility model have been disclosed in a concrete mixing device that is easy to clean, with the Chinese patent application number 201821054815.8. Its working principle is composed of elements such as springs, mass blocks, and motors. When the spring or mass block is subjected to an external force from the motor, elastic deformation or displacement will occur, thereby generating vibration.

[0039] The working principle and usage process of the present utility model: When the device is needed to screen the lithium manganate cathode material, if it is not necessary to classify the lithium manganate cathode material, the upper box body 3 stays on the lower box body 8. If it is necessary to classify the lithium manganate cathode material, the reduction motor 57 on the connecting frame 56 in the grading and filtering device 5 is started. The reduction motor 57 drives the lead screw 58 to rotate. The lead screw 58 is threadedly connected to the moving frame 59, and the inner top surface of the moving frame 59 is in close contact with the outer top surface of the connecting frame 56. Therefore, the lead screw 58 drives the moving frame 59 and structures such as the upper box body 3 to move until the structures such as the upper box body 3 move above the separation box 51. Then, the material is fed into the upper box body 3 through the two feeding components 4, and the screening component 2 is manipulated to screen it. If the upper box body 3 is above the lower box body 8, the screened lithium manganate cathode material falls into the lower box body 8 and is then discharged through the discharging component 7. If the upper box body 3 is above the separation box 51, the screened lithium manganate cathode material falls into the separation box 51 and is then graded and filtered by the upper filter screen 52 and the lower filter screen 53. The graded materials respectively fall onto the upper filter screen 52, the lower filter screen 53, and the inner bottom of the separation box 51. Then, the staff can unscrew the closing block 54 and the two threaded blocks 55 to take out the materials at each position respectively, and the work is completed. When it is necessary to adjust the height of the structures such as the lower box body 8, the staff can start the two electric telescopic rods 63 in the lifting and vibrating device 6, thereby driving the support plate 1 and the structures thereon to move up and down, so as to adjust the height of the structures such as the lower box body 8. When it is necessary to prevent the lithium manganate cathode material from staying at a certain position during the working process, start each vibrator 64 to drive the connecting plate 65 and the support plate 1 and other structures to vibrate, and then drive the structures such as the lower box body 8 to vibrate, thereby preventing the lithium manganate cathode material from staying at a certain position during the working process. The damper 62 and the elastic rubber frame 66 between the connecting plate 65 and the bottom plate 61 can buffer the vibration.
