[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Embodiment 1: A separation device for recycling waste materials of positive and negative electrodes of lithium batteries, such as Figure 1-Figure 4 As shown, it includes a feed barrel 1 and a discharge barrel 2, and the discharge barrel 2 has a left chamber and a right chamber. A connecting ring 3 is connected between the feed barrel 1 and the discharge barrel 2. A conical filter disc 4 and a flat filter disc 5 are fixedly connected in the middle of the connecting ring 3. The conical filter disc 4 is located above the flat filter disc 5, and the flat filter disc 5 is located above the right chamber of the discharge barrel 2. According to actual conditions, the aperture of the filter holes of the conical filter disc 4 and the flat filter disc 5 is selected between the maximum particle size of the positive electrode material and the minimum particle size of the negative electrode material, so that the particle size of the positive electrode material (such as lithium iron phosphate) is small and can pass through the filter hole and fall into the right chamber of the discharge barrel 2. The particle size of the negative electrode material (such as graphite) is large and cannot pass through the filter hole, and is retained on the conical filter disc 4 and the flat filter disc 5. The feed barrel 1 and the discharge barrel 2 are bolted together by two connecting threaded frames 6 and nuts 7. Two vibrators 8 are fixedly connected to the outside of the connecting ring 3 by bolts. The top of the feed barrel 1 is connected to a separation pipe 9 by plugging. The separation pipe 9 is composed of long tubes and short tubes distributed circumferentially, and the long tubes and the short tubes are distributed alternately. The short tube is located above the conical filter disk 4 and is used to adsorb the negative electrode material above the conical filter disk 4. The long tube passes downward through the conical filter disk 4 to adsorb the negative electrode material of the plane filter disk 5. The left side of the separation pipe 9 is connected to a suction device 10. The air flow intensity of the suction device 10 is selected to be moderate. The suction device 10 is connected to the left chamber of the discharge barrel 2 by plugging. A filter plate 11 is fixed in the long tube of the separation pipe 9. The long tube of the separation pipe 9 is connected to a baffle 12. The filter plate 11 is tilted downward toward the adjacent baffle 12 side. An outlet is opened at the bottom of the baffle 12 to guide the waste material to the conical filter disk 4.

[0035] First, the feed barrel 1 is connected with the discharge pipe of the crushing and disassembling machine, and the waste materials of the positive and negative electrodes of the lithium battery are dropped onto the conical filter disc 4 through the feed barrel 1. Under the guidance of the conical filter disc 4, the waste materials are quickly dispersed, and the vibrator 8 is started. The vibration generated by the vibrator 8 is transmitted to the conical filter disc 4 and the flat filter disc 5 through the connecting ring 3. In this way, the small and heavy positive electrode materials pass through the conical filter disc 4 downward, and the large and light negative electrode materials remain on the conical filter disc 4, and gather along the conical surface and roll to the edge of the conical filter disc 4. The suction device 10 is started, and under the effect of the back-suction wind force, the negative electrode materials remaining on the conical filter disc 4 are sucked into the suction device 10 through the short tube at the edge of the separation pipe 9, and then discharged through the left chamber of the discharge barrel 2, while the negative electrode materials passing through the conical filter The positive electrode material on the plate 4 and a small amount of negative electrode material mixed therein fall onto the plane filter plate 5 together. Under the vibration of the vibrator 8, the plane filter plate 5 separates the positive electrode material and a small amount of negative electrode material mixed thereon at a high frequency. The positive electrode material continues to pass downward through the plane filter plate 5, and then is discharged through the right chamber of the discharge barrel 2, while the mixed negative electrode material remains on the plane filter plate 5 and is sucked upward through the long tube of the separation pipe 9. Since the filter plate 11 arranged in the long tube of the separation pipe 9 only allows air circulation, the negative electrode material on the plane filter plate 5 and the small amount of positive electrode material sucked in are blocked by the filter plate 11 and guided into the baffle 12, and fall back onto the conical filter plate 4 through the outlet at the bottom of the baffle 12 for secondary screening and air separation.

[0036] In summary, the present invention makes the device easy to disassemble, repair and clean through splicing. At the same time, multi-stage separation can be achieved through the double-layer screening design. The upper conical filter disc 4 is mainly used for preliminary screening, and the lower flat filter disc 5 is used for fine screening, so that the positive and negative electrode materials can be separated more thoroughly, the mixing of impurities can be reduced, and the purity of the recycled materials can be improved.

[0037] The present invention can better diffuse the falling waste materials, reduce local accumulation, and improve the screening effect through the conical design of the conical filter plate 4. At the same time, the conical design helps the material to flow smoothly and reduce blockage.

[0038] The present invention can effectively adsorb the negative electrode materials on the conical filter plate 4 and the flat filter plate 5 respectively through the separation pipe 9 and the suction device 10, prevent the negative electrode materials from being sieved and falling together with the positive electrode materials, significantly improve the separation accuracy of the positive and negative electrode materials, and reduce impurities in the mixture.

[0039] The present invention provides a filter plate 11 and a baffle 12 so that the waste on the flat filter disc 5 falls back onto the conical filter disc 4 for secondary screening and air separation. This circulation design can ensure that all negative electrode materials can be fully separated to avoid waste. Through multiple filtration and adsorption, the recovery rate and purity of the negative electrode materials can be maximized.

[0040] like Fig.11 As shown, it also includes an electromagnetic rod 25 corresponding to the long tube of the separation pipe 9. The electromagnetic rod 25 is fixedly connected to one side of the separation pipe 9 close to the filter plate 11. The electromagnet is located at one end of the electromagnetic rod 25 close to the filter plate 11. A magnetic frame 26 is slidably connected between the electromagnetic rod 25 and the separation pipe 9. When power is turned on, the magnetic frame 26 and the electromagnetic rod 25 are magnetically attracted to each other. A tension spring 27 is fixedly connected between the magnetic frame 26 and the adjacent electromagnetic rod 25. The lower part of the magnetic frame 26 is rotatably connected to a rotating plate 28. The rotating plate 28 is located below the adjacent filter plate 11. The separation pipe 9 is used to limit the rotating plate 28.

[0041] Due to the influence of suction, the waste blocked by the filter plate 11 is difficult to be smoothly guided into the baffle 12. In order to assist in smoothly guiding it into the baffle 12, the electromagnetic rod 25 is controlled to be intermittently powered on and off. When powered on, the magnetic frame 26 intermittently moves to the side close to the baffle 12 under the magnetic attraction of the electromagnet at the end of the electromagnetic rod 25. The tension spring 27 is stretched, and the magnetic frame 26 drives the rotating plate 28 to move horizontally to the side close to the baffle 12. During the movement, the magnetic frame 26 gradually blocks the suction above the filter plate 11, so that the waste blocked by the filter plate 11 The trapped waste gradually falls onto the rotating plate 28 below until the rotating plate 28 breaks away from the limit of the separation pipe 9. At this time, the rotating plate 28 swings downward under the action of gravity until it is tilted and supported on the side of the separation pipe 9 close to the baffle 12. In this way, the waste blocked by the filter plate 11 can be more smoothly guided into the baffle 12 through the tilted rotating plate 28. When the power is off, the magnetic frame 26 drives the rotating plate 28 to move in the opposite direction due to the reset action of the tension spring 27. During the reverse movement, the rotating plate 28 is squeezed by the separation pipe 9 and swings upward to reset.

[0042] Embodiment 2: Based on embodiment 1, Figure 5 As shown, it also includes a positioning rod 13 corresponding to the connecting threaded frame 6, the positioning rod 13 is clamped between the corresponding connecting threaded frame 6 and the feed barrel 1, the feed barrel 1 and the discharge barrel 2 are both slidably connected to the connecting ring 3, when the vibrator 8 vibrates, the connecting ring 3 slides up and down along the feed barrel 1 and the discharge barrel 2, the positioning rod 13 is wound with a first spring 14 symmetrically distributed along the upper and lower parts of the positioning rod 13, the two ends of the first spring 14 on the upper side are respectively fixed to the feed barrel 1 and the connecting ring 3, and the two ends of the first spring 14 on the lower side are respectively fixed to the connecting threaded frame 6 and the connecting ring 3.

[0043] In addition to being transmitted to the conical filter disc 4 and the flat filter disc 5 through the connecting ring 3, the high-frequency vibration of the vibrator 8 will also be dispersed and transmitted to the rest of the entire equipment. Long-term high-frequency vibration may cause the connections to loosen, affecting the stability of the equipment connection. In order to weaken this effect, the connecting ring 3 is set to slide up and down along the positioning rod 13, and the elastic characteristics of the first spring 14 can effectively buffer and isolate vibrations, reduce the degree of vibration transmission to other parts of the equipment, improve the stability of the equipment connection, thereby extending the service life of the equipment, and make most of the vibrations mainly transmitted to the conical filter disc 4 and the flat filter disc 5 through the connecting ring 3.

[0044] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 7 As shown, it also includes a motor 15, which is fixedly connected to the right chamber of the discharge barrel 2. The output shaft of the motor 15 is splined with a rotating rod 16, which longitudinally penetrates the conical filter plate 4 and the flat filter plate 5, and the conical filter plate 4 and the flat filter plate 5 are both rotatably connected to the rotating rod 16. A conical ring 17 is fixedly connected to the top of the conical filter plate 4, and a material guide frame 18 is fixedly connected to the rotating rod 16. The material guide frame 18 is rotatably connected to the flat filter plate 5. A stirring frame 19 is connected to the top of the rotating rod 16. The stirring frame 19 is rotatably connected to the top of the conical filter plate 4. The stirring frame 19 is located in the conical ring 17. Three circumferentially distributed shovel plates 191 are fixedly connected to the edge of the stirring frame 19, and the shovel plates 191 are in contact with the inner side surface of the conical ring 17.

[0045] In order to prevent the positive electrode material from quickly sliding down to the edge of the conical filter disc 4 along with the negative electrode material before passing through the filter holes of the conical filter disc 4, thereby affecting the adsorption of the negative electrode material, the following operations are required to enhance the filtering effect: first, the waste material falling on the conical filter disc 4 is surrounded by the conical ring 17 to extend the time for the positive electrode material to pass downward through the conical filter disc 4, and at the same time, the motor 15 is started, and the output shaft of the motor 15 drives the rotating rod 16 to rotate, thereby driving the stirring frame 19 to rotate, and the stirring frame 19 fully stirs the waste material in the conical ring 17 to accelerate the screening of the positive electrode material and the negative electrode material on the conical filter disc 4. In this way, more and faster positive electrode materials can pass downward through the conical filter disc 4, while the negative electrode materials will gather along the conical surface of the conical filter disc 4 and slide to the inner side of the conical ring 17. When the stirring frame 19 rotates, it drives the shovel plate 191 to rotate synchronously, so that most of the negative electrode materials are shoveled upward to the outside of the conical ring 17, and continue to slide to the edge of the conical filter disc 4 for wind adsorption.

[0046] When the rotating rod 16 rotates, it also drives the guide frame 18 to rotate, so that the negative electrode material in the center of the plane filter disc 5 is affected by centrifugal force and diffuses toward the edge along the guide frame 18, so as to be better sucked away by the long tube of the separation pipe 9.

[0047] Embodiment 4: Based on embodiment 3, Figure 8-Figure 10 As shown, it also includes a torsion spring 20, the stirring frame 19 is rotatably connected to the rotating rod 16, and the torsion spring 20 is fixed between the stirring frame 19 and the rotating rod 16, the top of the rotating rod 16 is fixedly connected with a fixed block 201, and the top of the rotating rod 16 is slidably connected with a slide 21 along the left and right directions, and the slide 21 is provided with an inclined surface on the side close to the fixed block 201, and the fixed block 201 contacts the inclined surface of the slide 21, and the fixed block 201 is used to squeeze the slide 21 to slide to the right, and the inside of the feed barrel 1 is slidably connected with a guide ring 22 along the up and down directions, and the inner and outer sides of the guide ring 22 are both set to conical surfaces, and the slide 21 contacts the outer side of the guide ring 22, and the slide 21 is used to squeeze the guide ring 22 to slide upward, and the feed barrel 1 is slidably connected with two slide plates 23 along the left and right directions, and the bottom of the slide plate 23 contacts the inner side of the guide ring 22, and the guide ring 22 is used to squeeze the two slide plates 23 close to each other, and two second springs 24 are fixed between the two slide plates 23.

[0048] When the stirring frame 19 is not blocked, the rotating rod 16 drives the stirring frame 19 to rotate synchronously through the torsion spring 20. When the stirring frame 19 is blocked, the rotating rod 16 first rotates relative to the stirring frame 19, and the torsion spring 20 is deformed. When the force of the deformation of the torsion spring 20 can resist the obstructed force of the stirring frame 19, the rotating rod 16 drives the stirring frame 19 to rotate synchronously through the deformed torsion spring 20. In this way, when the more waste to be screened on the conical filter plate 4, the greater the obstruction of the stirring frame 19, the greater the angle of rotation of the rotating rod 16 relative to the stirring frame 19, and the torsion spring 20 is The greater the degree of deformation, the greater the angle at which the rotating rod 16 drives the fixed block 201 to rotate, the longer the distance that the fixed block 201 pushes the slide 21 to move to the right, the longer the distance that the slide 21 squeezes the guide ring 22 to move upward, the guide ring 22 squeezes the two slides 23 closer to each other, and makes the distance between the two slides 23 closer, thereby automatically reducing the amount of waste fed to the conical filter disc 4. Similarly, when the amount of waste to be screened on the conical filter disc 4 is less, the amount of waste fed to the conical filter disc 4 is automatically increased.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the appended claims of the application.
