Description

Technical Field

[0001] This utility model belongs to the field of battery recycling technology, and in particular relates to an automatic sorting device for crushed lithium battery materials. Background Technology

[0002] In the current battery recycling industry, the recycling and processing of lithium batteries is an important and challenging aspect. Because lithium batteries contain a variety of harmful substances, such as heavy metals and electrolytes, improper handling can not only cause serious environmental pollution but also harm the health of operators.

[0003] According to a public announcement (publication number: CN222019727U), a waste lithium battery crushing and sorting device designed to avoid environmental pollution includes a supporting frame. A sorting box is fixedly mounted on the top side of the supporting frame, and a recycling box is fixedly mounted on the side of the sorting box away from the supporting frame. An exhaust hopper is movably placed on top of the sorting box and the recycling box. An exhaust gas treatment component for recycling waste gas generated during the sorting process is installed on top of the exhaust hopper. The sorting box is filled with sorting water. This utility model, with its sorting box and recycling box, allows sufficient tap water to be poured into the sorting box. Crushed waste lithium battery fragments are then poured into the sorting box. Plastic fragments float on the water surface, while metal fragments sink to the bottom of the sorting box. Utilizing the density difference between plastic and metal, reverse separation is achieved. Compared to magnetic separation, this method achieves more thorough separation between plastic and metal fragments.

[0004] In the aforementioned application, the method of separating plastic fragments from metal fragments by filling the sorting box with sorting water and using the density difference between plastic and metal can achieve separation to a certain extent. However, if the waste gas and wastewater generated in the process are not properly treated, they will still cause environmental pollution. Therefore, we propose an automatic sorting device for lithium battery crushed materials. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic sorting device for crushed lithium battery materials. By cooperating with the mounting plate, suction hood and suction pipe in the pollution filtration device, it solves the problem that existing devices cannot effectively treat the dust and harmful gases generated during the sorting process of crushed lithium battery materials.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an automatic sorting device for crushed lithium battery materials, including a crushing and screening machine, a conveying device on the side of the crushing and screening machine, and a contamination filtration device on the top of the crushing and screening machine.

[0008] The pollution filtration device includes a mounting plate fixedly connected to the side of the crushing and screening machine. A suction hood is fixedly connected to the side of the mounting plate, and a suction pipe is fixedly connected to the top of the suction hood. A wind box is fixedly connected to the end of the suction pipe away from the suction hood. A connecting plate is fixedly connected to the inner wall of the wind box, and a rotating sleeve is fixedly connected to the side of the connecting plate. A rotating shaft is rotatably connected to the inner wall of the rotating sleeve. A fan blade is fixedly connected to one end of the rotating shaft, and a driven bevel gear is fixedly connected to the end of the rotating shaft away from the fan blade. A locking plate is fixedly connected to the side of the wind box, and a motor is fixedly connected to the side of the locking plate. A driving bevel gear is fixedly connected to the output shaft of the motor.

[0009] Furthermore, a protective plate is fixedly connected to the inner wall of the suction hood, and a filter cotton box is provided on the side of the air box. This facilitates the preliminary filtration of the intake air, preventing larger particles of impurities from entering the air box, thereby protecting components such as the fan blades from damage. At the same time, the filter cotton box can be easily disassembled and replaced to ensure the filtration effect.

[0010] Furthermore, the suction hood is located at the top of the crushing and screening machine, and the output shaft of the motor is rotatably connected to the side of the air box. This allows the suction hood to more effectively capture the dust and harmful gases generated during the operation of the crushing and screening machine. The rotatable connection between the motor output shaft and the side of the air box ensures that the motor can stably drive the active bevel gear to rotate, thereby realizing the power transmission of the entire pollution filtration device.

[0011] Furthermore, the driving bevel gear and the driven bevel gear mesh with each other, and the number of teeth of the driving bevel gear is less than that of the driven bevel gear. This is beneficial to the difference in the number of teeth between the driving bevel gear and the driven bevel gear, which achieves the effect of speed reduction and torque increase, so that the fan blade can obtain a large torque at a lower speed.

[0012] Furthermore, a liquid recovery device is provided at the bottom of the crushing and screening machine. The liquid recovery device includes a water receiving tray, which is located at the bottom of the crushing and screening machine. A water suction pipe is fixedly connected to the side of the water receiving tray. An acid-resistant water pump is fixedly connected to the side of the air box. A driven gear is fixedly connected to the input shaft of the acid-resistant water pump. A driving gear is fixedly connected to the circumferential surface of the motor output shaft. A water outlet pipe is provided on the side of the acid-resistant water pump. This facilitates the timely and effective recovery and treatment of electrolyte-containing wastewater generated during the operation of the crushing and screening machine. The driving gear is driven to rotate by the motor output shaft, and the driving gear and the driven gear mesh with each other, thereby driving the acid-resistant water pump to work.

[0013] Furthermore, a regulating valve is provided on the circumferential surface of the pumping pipe, and a filter plate is provided on the side of the receiving tray. This allows the regulating valve to flexibly control the flow rate of the liquid in the pumping pipe and adjust the wastewater recovery speed according to actual needs. The filter plate can perform preliminary filtration of the wastewater entering the receiving tray, intercepting larger solid impurities to prevent them from entering the pumping pipe and causing blockage, thus ensuring the stable operation of the liquid recovery device.

[0014] Furthermore, the driving gear and the driven gear mesh with each other, and the driving gear has more teeth than the driven gear. This difference in the number of teeth between the driving gear and the driven gear is beneficial to achieving a speed increase effect. This allows the acid-resistant water pump to obtain sufficient power to pump the electrolyte-containing wastewater from the water receiving tray under the drive of the motor at a lower speed, thereby improving the efficiency of liquid recovery.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves effective capture and suction of dust and harmful gases generated during the operation of the crushing and screening machine through the cooperation of the mounting plate, suction hood and suction pipe in the pollution filtration device, preventing them from spreading into the surrounding environment and causing harm to the health of operators, while also avoiding environmental pollution. The negative pressure generated by the rotation of the fan blades in the air box allows the suction hood to continuously draw in air containing dust and harmful gases, and then transport it to the subsequent processing stage through the suction pipe.

[0017] 2. This utility model, through the coordinated operation of the water receiving tray, water pump, and acid-resistant water pump in the liquid recovery device, achieves timely and effective collection and treatment of electrolyte-containing wastewater generated during the operation of the crushing and screening machine. This avoids pollution to the environment caused by indiscriminate discharge of wastewater, and in particular, prevents harmful substances in the electrolyte from seeping into the soil and groundwater, ensuring the safety of the ecological environment. The setting of the regulating valve and filter plate further optimizes the performance of the liquid recovery device. The regulating valve can flexibly control the wastewater recovery speed according to the actual situation, while the filter plate can effectively intercept larger solid impurities, prevent the water pump from being blocked, ensure the long-term stable operation of the liquid recovery device, and improve the practicality and reliability of the entire automatic sorting equipment for lithium battery crushed materials.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is an automatic sorting device for crushed lithium battery materials, including a crushing and screening machine 1, a conveying device 2 on the side of the crushing and screening machine 1, and a contamination filtration device 3 on the top of the crushing and screening machine 1.

[0029] The pollution filtration device 3 includes a mounting plate 301, which is fixedly connected to the side of the crushing and screening machine 1. A suction hood 302 is fixedly connected to the side of the mounting plate 301. A suction pipe 303 is fixedly connected to the top of the suction hood 302. A wind box 304 is fixedly connected to the end of the suction pipe 303 away from the suction hood 302. A connecting plate 305 is fixedly connected to the inner wall of the wind box 304. A rotating sleeve 306 is fixedly connected to the side of the connecting plate 305. A rotating shaft 307 is rotatably connected to the inner wall of the rotating sleeve 306. A fan blade 308 is fixedly connected to one end of the rotating shaft 307. A driven bevel gear 309 is fixedly connected to the end of the rotating shaft 307 away from the fan blade 308. A locking plate 310 is fixedly connected to the side of the wind box 304. A motor 311 is fixedly connected to the side of the locking plate 310. A driving bevel gear 312 is fixedly connected to the output shaft of the motor 311.

[0030] As shown in the figure, a protective plate 4 is fixedly connected to the inner wall of the suction hood 302, and a filter cotton box 5 is provided on the side of the air box 304. This facilitates the preliminary filtration of the intake air, prevents larger particles of impurities from entering the air box 304, and protects components such as the fan blade 308 from damage. At the same time, the filter cotton box 5 can be easily disassembled and replaced to ensure the filtration effect.

[0031] As shown in the figure, the suction hood 302 is located on the top of the crushing and screening machine 1. The output shaft of the motor 311 is connected to the side of the air box 304 through and rotatably. This allows the suction hood 302 to more effectively capture the dust and harmful gases generated by the crushing and screening machine 1 during operation. The through and rotatable connection between the output shaft of the motor 311 and the side of the air box 304 ensures that the motor 311 can stably drive the active bevel gear 312 to rotate, thereby realizing the power transmission of the entire pollution filtration device 3.

[0032] As shown in the figure, the driving bevel gear 312 and the driven bevel gear 309 mesh with each other. The number of teeth of the driving bevel gear 312 is less than the number of teeth of the driven bevel gear 309. This is beneficial to the difference in the number of teeth between the driving bevel gear 312 and the driven bevel gear 309, which achieves the effect of speed reduction and torque increase, so that the fan blade 308 can obtain a large torque at a lower speed.

[0033] As shown in the figure, a liquid recovery device 6 is provided at the bottom of the crushing and screening machine 1. The liquid recovery device 6 includes a water receiving tray 601, which is located at the bottom of the crushing and screening machine 1. A water suction pipe 602 is fixedly connected to the side of the water receiving tray 601. An acid-resistant water pump 603 is fixedly connected to the side of the air box 304. A driven gear 604 is fixedly connected to the input shaft of the acid-resistant water pump 603. A driving gear 605 is fixedly connected to the circumferential surface of the output shaft of the motor 311. A water outlet pipe 606 is provided on the side of the acid-resistant water pump 603. This facilitates the timely and effective recovery and treatment of the electrolyte-containing wastewater generated during the operation of the crushing and screening machine 1. The output shaft of the motor 311 drives the driving gear 605 to rotate. The driving gear 605 and the driven gear 604 mesh with each other, thereby driving the acid-resistant water pump 603 to work.

[0034] As shown in the figure, a regulating valve 7 is provided on the circumferential surface of the water pumping pipe 602, and a filter plate 8 is provided on the side of the water receiving tray 601. This allows the regulating valve 7 to flexibly control the flow rate of the liquid in the water pumping pipe 602 and adjust the wastewater recovery speed according to actual needs. The filter plate 8 can perform preliminary filtration on the wastewater entering the water receiving tray 601, intercepting larger solid impurities and preventing them from entering the water pumping pipe 602 and causing blockage, thus ensuring the stable operation of the liquid recovery device 6.

[0035] As shown in the figure, the driving gear 605 and the driven gear 604 mesh with each other. The driving gear 605 has more teeth than the driven gear 604. This difference in the number of teeth between the driving gear 605 and the driven gear 604 is beneficial to achieving the speed increase effect. This allows the acid-resistant water pump 603 to obtain sufficient power to pump the electrolyte-containing wastewater from the water receiving pan 601 under the drive of the motor 311 at a relatively low speed, thereby improving the efficiency of liquid recovery.

[0036] A specific application of this embodiment is as follows: Workers throw waste batteries into the crushing and screening machine 1, then start the equipment. The motor 311 begins to run, and its output shaft drives the driving bevel gear 312 and the driving gear 605 to rotate simultaneously. The driving bevel gear 312 meshes with the driven bevel gear 309. Because the driving bevel gear 312 has fewer teeth than the driven bevel gear 309, it achieves speed reduction and torque increase, driving the fan blades 308 on the rotating shaft 307 to rotate slowly and powerfully. The suction hood 302 is located at the top of the crushing and screening machine 1 and can effectively capture dust and harmful gases generated during the crushing process. These pollutants are then drawn into the air box 304 through the suction pipe 303. Air entering the air box 304 is first initially blocked by the protective plate 4, reducing larger particulate impurities, and then further filtered by the filter cotton box 5, allowing cleaner air to be discharged, reducing environmental pollution. The driving gear 605 and the driven gear 604 mesh with each other. Because the driving gear 605 has more teeth than the driven gear 604, a speed-increasing effect is achieved, driving the acid-resistant water pump 603 to operate rapidly. The wastewater containing electrolyte generated by the crushing and screening machine 1 flows into the bottom water receiving tray 601. After being initially filtered by the filter plate 8 to intercept larger solid impurities, the wastewater entering the water receiving tray 601 is drawn by the acid-resistant water pump 603 through the water pump pipe 602. The regulating valve 7 can flexibly control the flow rate of the liquid in the water pump pipe 602 according to actual needs, adjusting the wastewater recovery speed. The acid-resistant water pump 603 pumps the extracted electrolyte-containing wastewater through the outlet pipe 606 to the subsequent treatment stage, realizing timely and effective recycling and treatment of the electrolyte-containing wastewater. Meanwhile, the conveying device 2 conveys the materials sorted by the crushing and screening machine 1 to the designated location, completing the entire automatic sorting process of lithium battery crushed materials.
