[0002] Nickel-metal hydride batteries are rechargeable batteries that are mainly made of nickel oxide as the positive electrode material and hydrogen storage alloy as the negative electrode material. They conduct current between the electrodes through ions in the electrolyte and are widely used in electronic devices, electric vehicles, hybrid vehicles and other fields. With the popularity of nickel-metal hydride batteries, the utilization of related waste has also attracted people's attention. Discarded nickel-metal hydride batteries contain a variety of recyclable materials, such as metals such as nickel and cobalt, which can be extracted through mechanical treatment, chemical leaching and other methods and reused in new batteries or other industrial production. In addition, hydrogen storage alloys also contain metals such as aluminum and manganese, which also have recycling value. When dealing with nickel-metal hydride battery waste, effective pollution control measures can also be taken to reduce the impact of heavy metals and chemicals on the environment, which meets the requirements of sustainable development. Therefore, nickel-metal hydride batteries not only occupy an important position in the field of energy storage, but their potential for waste utilization and resource recovery also provides a good opportunity to promote the circular economy.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1 to 6In an embodiment of the present invention, a comprehensive recycling device for waste nickel-hydrogen batteries includes a frame assembly 1, which includes an outer stacking barrel 101 for storing processed iron materials, an inner barrel 102 is fixedly connected to the center of the lower side wall of the outer stacking barrel 101, a filter screen 103 for passing gas to absorb impurities other than iron materials is fixedly connected inside the inner barrel 102, an iron ring is fixedly connected to the center of the filter screen 103, and a wind tube 104 is rotatably connected to the wind tube through the iron ring and the bearing installed inside the wind tube. 104 is fixedly connected to the center of the lower side wall of the dustproof cylinder 105, and the inside of the dustproof cylinder 105 is fixedly connected to the annular track housing 106 through a connecting rod 107. A plurality of connecting rods 107 are fixedly connected between the inner side wall of the annular track housing 106 and the dustproof cylinder 105 by welding. The inside of the annular track housing 106 is rotatably connected to an annular block 108 by a sliding groove clamping method. The side wall of the annular block 108 is provided with a tooth surface, and the upper side wall of the annular block 108 is fixedly connected to a plurality of uniformly distributed guide short rods 109;

[0036] A driving assembly 2 for driving the adsorption and removal assembly 3 to rotate is arranged on the upper side of the dustproof cylinder 105, a plurality of evenly distributed adsorption and removal assemblies 3 for adsorbing iron materials are arranged on the annular track shell 106, and an exhaust assembly 4 for clearing blockage is fixedly connected to the lower end of the wind cylinder 104.

[0037] The driving component 2 includes a circular plate 201, and the circular plate 201 is rotatably connected to the upper end of the dustproof cylinder 105. A plurality of fixing rods 202 are fixedly connected between the circular plate 201 and the outer stacking cylinder 101 by bolts. A motor 203 is fixedly connected to the upper side wall of the circular plate 201. The structure and principle of the motor 203 are all prior art and are not described herein. The output end of the motor 203 is rotatably connected to the wind cylinder 104. When the motor 203 is started, the motor 203 can drive the dustproof cylinder 105 to rotate through the wind cylinder 104, and at the same time drive the plurality of adsorption and impurity removal components 3 to rotate.

[0038] The inner wall of the dustproof cylinder 105 is fixedly connected to a support plate 205, and the upper wall of the support plate 205 is rotatably connected to a gear 206 that meshes with the annular block 108. The upper wall of the gear 206 is fixedly connected to a transmission rod 207 by welding, and the upper end of the transmission rod 207 is fixedly connected to a transmission wheel 208, and the lower wall of the circular plate 201 is fixedly connected to an annular toothed plate 204 that meshes with the transmission wheel 208. During the rotation of the dustproof cylinder 105 and the annular rail housing 106, since the circular plate 201 is fixed to the inner wall of the outer stacking cylinder 101, the circular plate 201 is no longer in a rotating state. Therefore, the dustproof cylinder 105 will drive the transmission wheel 208 to rotate through the support plate 205, so that the transmission wheel 208 is in meshing with the annular toothed plate 204, and the transmission wheel 208 drives the gear 206 to rotate together through the transmission rod 207, and the gear 206 will drive the annular block 108 to rotate during the rotation.

[0039] The adsorption and impurity removal component 3 includes a connecting block 301, a square groove is bored on the upper side wall of the connecting block 301, and the connecting block 301 is fixedly connected to the side wall of the annular rail shell 106 by welding through the square groove, and a guide wheel 302 is rotatably connected to the side wall of the connecting block 301 by a sliding groove clamping method, and a plurality of annular guide grooves 303 are bored on the inner side wall of the guide wheel 302, and the guide short rod 109 is located inside the guide groove 303. During the movement of the plurality of guide short rods 109, the guide short rod 109 will push the guide wheel 302 to rotate through the guide groove 303, thereby driving the belt 307 to move.

[0040] The guide wheel 302 is provided with a pulley 304 on the side away from the wind tube 104. The guide wheel 302 and the two side walls of the pulley 304 are fixedly connected with ring blocks 305 by welding. The two ring blocks 305 on the same side are rotatably connected with the sealing plate 306 through a mechanical seal. The sealing plate 306 and the dustproof cylinder 105 are fixedly connected by welding. The same belt 307 is sleeved between the pulley 304 and the guide wheel 302. The left and right side walls of the belt 307 are fixedly connected with rubber ropes. The side walls opposite to the two sealing plates 306 are each cut with rubber ropes. A matching elliptical track, and the rubber rope is located inside the elliptical track, the inside of the elliptical track is coated with lubricating oil, the lubricating oil is used to reduce friction, so as to improve the sealing inside the adsorption and impurity removal component 3. In addition, the rubber rope and the elliptical track are not shown in the figure. An electromagnet 308 is fixedly connected between the two sealing plates 306, and an air duct 309 is fixedly connected between the sealing plate 306 and the wind tube 104. The electromagnet 308 is powered by a collector ring, and the collector ring is installed on the wind tube 104. The structure and principle of the electromagnet 308 are all existing technologies and will not be repeated here.

[0041] Example 2: Please refer to Figures 7 and 8Based on Example 1, the exhaust assembly 4 includes a valve housing 401, and the valve housing 401 is connected and fixedly connected to the lower end of the wind tube 104 by welding. The valve core 402 is rotatably connected to the output end of the regulating motor 406 inside the valve housing 401, and a fan 403 is installed inside the valve core 402. Under normal circumstances, the exhaust end of the fan 403 is set upward and the suction end is set downward. A supporting horizontal bar 404 is fixedly connected between the valve housing 401 and the inner wall of the inner cylinder 102 by welding. The lower end of the valve housing 401 is fixed and connected to the output end. The air pipe 405, when the fan 403 is started, will blow the air inside the inner cylinder 102 to the inside of the adsorption and impurity removal component 3. After the electromagnet 308 attracts the iron material, the wind will be transmitted to the inside of the adsorption and impurity removal component 3 through the wind tube 104 and the air pipe 309, and finally discharged through the belt 307, and the impurities on the surface of the adsorbed iron material will be removed. At the same time, since the inside of the inner cylinder 102 is in a negative pressure state, the filter net 103 will generate suction at this time, and the iron material and impurities will be adsorbed together to prevent dust and impurities from floating in the air and affecting the purity of the iron material.

[0042] An adjusting cylinder 407 is inserted and fixed on the side wall of the inner cylinder 102, an adjusting motor 406 is fixedly connected between one end of the adjusting cylinder 407 and the valve housing 401, and the output end of the adjusting motor 406 is fixedly connected to the valve core 402, a piston 408 is slidably connected inside the adjusting cylinder 407, a spring plate 409 is fixedly connected inside the adjusting cylinder 407, a connecting spring 411 is fixedly connected between the piston 408 and the spring plate 409, and an insert rod 410 that passes through the spring plate 409 is fixedly connected to the side wall of the piston 408. When the connecting spring 411 is not under force, the insert rod 410 can press a control button 412 installed at the end of the adjusting cylinder 407 away from the adjusting motor 406, so that the exhaust end of the fan 403 can be set upward, one end of the adjusting motor 406 and the inner side wall of the end of the adjusting cylinder 407 away from the adjusting motor 406 are fixedly connected with the control button 412, and the control button 412 is electrically connected to the regulating motor 406, and a plurality of evenly distributed vents 413 are provided at both ends of the regulating cylinder 407. When the filter 103 is blocked, the negative pressure inside the inner cylinder 102 increases, thereby sucking the piston 408 to move through the vent 413 until the piston 408 presses the control button 412 near the regulating motor 406, thereby starting the regulating motor 406 and driving the valve core 402 to rotate, so that the air cylinder 104 starts to inhale air and the air pipe 405 starts to exhaust air, so that a positive pressure is generated inside the inner cylinder 102. At this time, the filter 103 starts to exhaust air, blowing away impurities to play a role in clearing the blockage. Subsequently, after the piston 408 is no longer affected by the air pressure, it is pulled back instantly by the connected spring 411, so that the regulating motor 406 drives the valve core 402 to rotate again. At this time, the impurities blown up by the filter 103 will continue to be adsorbed, thereby improving the permeability of the filter 103.

[0043] In addition, the device also includes a power supply, a switch, a controller, a power supply cable and other devices, which are not the main technologies and will not be described in detail.

[0044] The working principle of the present invention is:

[0045] When the present invention is in use, first, the staff puts the iron materials separated from the battery by the magnetic separator into the filter screen 103 in the inner enclosure 102, and then starts the motor 203, the electromagnet 308 and the fan 403. The motor 203 drives the dustproof cylinder 105 and the adsorption and impurity removal component 3 to rotate synchronously through the air cylinder 104 and the air duct 309. During the rotation of the dustproof cylinder 105 and the annular rail shell 106, since the circular plate 201 is fixed to the inner wall of the outer stacking cylinder 101, the circular plate 201 is no longer in a rotating state. Therefore, the dustproof cylinder 105 will drive the transmission wheel 208 to rotate through the support plate 205, so that the transmission wheel 208 is meshed with the annular gear plate 204, and the transmission wheel 208 drives the gear 206 to rotate together through the transmission rod 207. The gear 206 drives the annular block 108 to rotate during the rotation process.

[0046] The annular block 108 rotates and drives the guide rods 109 to rotate together. When the multiple guide rods 109 pass through the guide grooves 303, they drive the top guide wheel 302 to rotate, thereby driving the belt 307 to move. The electromagnet 308 attracts the iron material to be adsorbed on the surface of the belt 307. Due to the movement of the belt 307, the iron material moves with the belt 307. When the iron material moves out of the magnetic attraction range of the electromagnet 308, it falls due to its own gravity. At this time, the iron material can just fall into the outer stacking barrel 101.

[0047] When the fan 403 is started, the air inside the inner cylinder 102 will be blown into the adsorption and impurity removal component 3. After the electromagnet 308 attracts the iron material, the wind will be transmitted to the inside of the adsorption and impurity removal component 3 through the wind tube 104 and the air duct 309, and finally discharged through the belt 307, and the impurities on the surface of the adsorbed iron material will be removed. At the same time, since the inner cylinder 102 is in a negative pressure state, the filter screen 103 will generate suction at this time, and the suction will adsorb the iron material and impurities together. When the iron material is adsorbed upward by the magnetic force, the impurities carried on the surface of the iron material can be reduced, and at the same time, dust and impurities can be prevented from floating in the air and affecting the purity of the iron material.

[0048] When the filter 103 is clogged, the negative pressure inside the inner cylinder 102 will increase, thereby sucking the piston 408 to move through the vent 413 until the piston 408 presses the control button 412 near the regulating motor 406, thereby starting the regulating motor 406 and driving the valve core 402 to rotate 180 degrees, changing the exhaust and intake positions of the valve core 402, allowing the air cylinder 104 to start inhaling, and the air pipe 405 to start exhausting, so that a positive pressure is generated inside the inner cylinder 102. At this time, the filter 103 starts to exhaust and blow away impurities, thereby playing a role in clearing the blockage. Subsequently, when the piston 408 is no longer affected by the air pressure, it is pulled back to its original position by the connected spring 411, so that the regulating motor 406 drives the valve core 402 to rotate again. At this time, the impurities blown up by the filter 103 will continue to be adsorbed, thereby improving the permeability of the filter 103.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
