Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery recycling and treatment, and particularly to a device and method for comprehensive utilization of lithium battery solid waste resources. Background Art

[0002] With the progress of technology, lithium batteries, as energy storage devices with high energy density, high efficiency and long life, are widely used in many fields such as electric vehicles, smart phones, and portable appliances. The 18650 lithium battery is a standard cylindrical lithium battery, named after its outer diameter of 18mm and height of 65mm. With its excellent performance and relatively low cost, this type of battery has become the mainstream power solution in fields such as consumer electronics and electric vehicles. Therefore, the demand for 18650 lithium batteries is also growing rapidly. After the battery's service life ends, the solid waste problem becomes increasingly prominent. According to research predictions, by 2025, the annual scrap volume of lithium batteries will reach several million tons. Abandoned lithium batteries not only occupy space but also may pose a serious threat to the environment. The materials in lithium batteries contain heavy metals such as cadmium, lead, and manganese. If not properly treated, they will pollute the soil and water sources, threatening the ecosystem and human health.

[0003] Currently, in response to the national environmental protection policy, through effective recycling and utilization of 18650 lithium batteries, the exploitation of new materials can be reduced and the resource utilization efficiency can be improved. Before treatment, the 18650 lithium batteries need to be put into a brine pool for soaking. After the internal power of the 18650 lithium batteries is completely diluted and consumed, this step is to reduce the safety risk of the battery and prevent short circuits or explosions during subsequent treatment. Then, a physical separation method is used to separate the lithium batteries, and physical methods are used to crush and separate this type of lithium battery. However, in the physical separation stage, especially in processes such as crushing, screening, and drying, the materials in the 18650 lithium batteries (such as electrolyte and positive and negative electrode materials) may volatilize or form dust, and form harmful gases, affecting the air quality of the working environment. Currently, some workers need to wear gas masks and other protective equipment when working, which increases the complexity and inconvenience of the operation. Moreover, the soaked batteries are usually naturally dried, and there will inevitably be water stains on the surface.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0037] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0038] Embodiment:

[0039] Referring to Figures 1 - 8 , a comprehensive utilization and treatment device for lithium battery solid waste resources, includes a working box 1. A crushing mechanism is also arranged in the working box 1 for crushing lithium batteries. The crushing mechanism mainly includes crushing rollers 3, which are arranged in the cavity of the working box 1, and two groups of crushing rollers 3 are symmetrically arranged. Driven by a driving box 4, each group of crushing rollers 3 rotates through the driving box 4, which is convenient for effectively physically crushing lithium batteries. Different crushing effects can be achieved by adjusting the spacing and rotation speed of the rollers. And the crushing rollers 3 can be made of wear-resistant materials, such as alloy steel or cemented carbide, to improve the wear resistance. The driving box 4 is provided with a motor and a reducer. The motor provides power, and the reducer is used to adjust the rotation speed and torque of the crushing rollers 3 to ensure the efficiency and stability of the crushing process.

[0040] A top cover 2 is also installed on the top of the working box 1, thus forming a semi-sealed environment, which helps to control the emission of waste gas and provides a path for subsequent material transportation. A conveying box 7 is arranged on the side wall of the working box 1. The output end of the conveying box 7 extends into the cavity of the top cover 2. A driving roller is rotatably connected to the conveying box 7, a conveyor belt 5 is sleeved on the driving roller, a blocking plate 6 is fixedly connected to the surface of the conveyor belt 5, a motor 18 is fixedly connected to the outer wall of the conveying box 7, the output end of the motor 18 is fixedly connected to the driving roller through a transmission shaft 19, and the transmission shaft 19 is connected to a connecting shaft through a transmission belt pulley. The output end of the motor 18 is connected to the driving roller through the transmission shaft 19, thereby driving the conveyor belt 5 to rotate. The arranged blocking plate 6 can effectively prevent the material from slipping during the transportation process, ensure the stable forward movement of the lithium battery, and convey it into the working box 1.

[0041] In order to dry the water stains on the surface of the lithium battery, a liftable filter plate 16 is also arranged in the cavity of the conveying box 7. A blocking plate 8 is arranged in the conveying box 7, and a blanking through hole 9 is opened on the blocking plate 8. The outer wall of the filter plate 16 fits with the surface of the blocking plate 8. When the filter plate 16 moves up and down, it can drive the lithium battery to move up and down, thereby shaking off the excess water stains. And a stirring mechanism is arranged on the conveying box 7, and the working end of the stirring mechanism is arranged above the filter plate 16. The lithium battery can be shaken through the stirring mechanism to promote the rapid evaporation or falling of the surface water stains.

[0042] It needs to be explained that when the filter plate 16 moves to the bottom of the feed hole 9, the lithium battery will fall onto the conveyor belt 5. When the filter plate 16 moves to the top of the feed hole 9, the channel of the feed hole 9 will be blocked, thereby achieving the effect of intermittent feeding. The feed hole 9 is closed to form a temporary barrier, which can prevent the lithium battery from falling randomly, thereby increasing the residence time of the lithium battery during the transportation process, thereby increasing the drying time of the water stains on the outer wall of the lithium battery by the jet mechanism.

[0043] Furthermore, the above-mentioned stirring mechanism includes a stirring plate 29, a hollow tube 26 is rotatably connected to the conveying box 7, the stirring plate 29 is fixedly connected to the hollow tube 26, and a connecting rod 22 is rotatably connected to the conveying box 7. The connecting rod 22 is connected to the hollow tube 26 through a transmission pulley. When the connecting rod 22 rotates, it can drive the hollow tube 26 to rotate synchronously, thereby causing the stirring plate 29 to rotate in the cavity of the conveying box 7.

[0044] In addition, a fixed block 14 is fixedly connected to the outer wall of the conveying box 7, a movable rod 15 is connected to the fixed block 14 for lifting, a connecting shaft is rotatably connected to the conveying box 7, a cam 20 is installed on the connecting shaft, a mounting rod 17 is fixedly connected to the filter plate 16, one end of the movable rod 15 is fixedly connected to the top of the mounting rod 17 through a connecting plate, the other end of the movable rod 15 is against the outer wall of the cam 20, and a rack 21 is fixedly connected to the outer wall of the movable rod 15, a gear 23 is fixedly connected to the connecting rod 22, and the rack 21 is meshed with the gear 23.

[0045] When the connecting rod 22 rotates, the stirring plate 29 starts to rotate. With the movement of the stirring plate 29, the lithium batteries are stirred in the conveying box 7, thereby improving the evaporation efficiency of water stains. At the same time, the lithium batteries can be helped to contact the hot air ejected by the jet mechanism, thereby promoting a better drying effect.

[0046] In order to drive the filter plate 16 to move up and down reciprocatingly, when the motor 18 drives the conveyor belt 5 to rotate, the transmission shaft 19 drives the connecting shaft to rotate through the transmission pulley, and then drives the cam 20 to rotate, so that the movable rod 15 can move back and forth on the fixed block 14. In order to reset the movable rod 15, a limit plate 24 is fixedly connected to the outer wall of the movable rod 15, and a reset spring 25 is provided on the limit plate 24, and the connecting end of the reset spring 25 is connected to the fixed block 14. When the movable rod 15 moves back and forth, the hollow tube 26 drives the stirring plate 29 to rotate synchronously. During the stirring process of the stirring plate 29, water stains may be shaken off or evaporated due to the force on the surface of the lithium battery. In combination with the jet mechanism, the effect of removing water stains on the surface of the lithium battery is improved, lithium and water are prevented from reacting to generate hydrogen, and the possibility of the reaction is reduced.

[0047] Furthermore, the jet mechanism includes a jet hole 30 provided on the stirring plate 29, the jet hole 30 is communicated with the hollow tube 26, and a negative pressure pump 10 is fixedly connected to the bottom of the conveying box 7, a jet plate 13 is fixedly connected in the cavity of the conveying box 7, and a working end of the jet plate 13 faces the bottom of the filter plate 16, which is used to jet the lithium batteries to be crushed, which can significantly reduce the accumulation of moisture on the surface of the lithium batteries and improve the drying efficiency.

[0048] In addition, the output end of the negative pressure pump 10 is connected to the hollow tube 26 and the jet plate 13, a limiting ring 27 is fixedly connected to the end of the hollow tube 26, a connecting cover 28 is fixedly connected to the fixed block 14, and the limiting ring 27 is arranged in the cavity of the connecting cover 28, and the connecting cover 28 is fixedly connected to the second pipe 42, so that when the hollow tube 26 rotates, the gas in the second pipe 42 can also be transported to the hollow tube 26 and then ejected from the jet hole 30.

[0049] In order to adsorb and purify the generated toxic gases, a negative pressure suction plate 37 is also installed on the top of the cavity of the top cover 2, and the adsorption end of the negative pressure suction plate 37 faces the crushing roller 3. A purification mechanism is arranged on the side wall of the conveying box 7, and the input end of the negative pressure suction plate 37 is connected to the input end of the purification mechanism. A heating mechanism is arranged at the bottom of the conveying box 7, and the purification mechanism cooperates with the heating mechanism.

[0050] The above-mentioned purification mechanism includes a liquid storage box 31 and a purification box 35 fixedly connected to the outer wall of the conveying box 7. The liquid storage box 31 is filled with disinfectant. Acidic detergent, such as sulfuric acid or hydrochloric acid, can be used to neutralize and remove some acidic or corrosive gases in the toxic gas.

[0051] A partition plate 32 is fixedly connected in the liquid storage tank 31, and the output end of the negative pressure pump 10 extends into the cavity of the liquid storage tank 31 through the air outlet pipe 39, and the input end of the negative pressure pump 10 is connected to the negative pressure suction plate 37 through the air inlet pipe 38. After the negative pressure pump 10 is started, the generated toxic gas will be adsorbed by the air inlet pipe 38 and transported to the liquid storage tank 31. At this time, the toxic gas will react with the disinfectant to remove part of the acidic or corrosive gas in the toxic gas. At the same time, the partition plate 32 can increase the reaction time of the toxic gas and the disinfectant. The disinfected gas will be transported to the purification box 35 through the connecting pipe 40. In addition, an extension rod 33 is rotatably connected to the liquid storage tank 31, and the extension rod 33 is transmission-connected to the hollow tube 26 through a transmission pulley, and the extension rod 33 extends to the liquid storage tank 31 and is fixedly connected with a stirring paddle 34 for stirring the disinfectant, thereby improving the neutralization and purification effect between the disinfectant and the harmful gas.

[0052] A purification filter plate 36 is provided inside the purification box 35. The purification filter plate 36 can use activated carbon, which can effectively perform active adsorption on the purified toxic gas. At this time, the gas is then transported to the heating box 11 through the first pipeline 41, and the gas is heated.

[0053] By adsorbing and purifying toxic gases, the emissions of these harmful substances can be effectively reduced, protecting the surrounding air and environmental quality, enabling workers to wear gas masks and other protective equipment less or not at all during work, improving practicality while also ensuring the health and safety of workers.

[0054] The heating mechanism includes the heating box 11. A temperature controller is also provided on the heating box 11 to observe the internal temperature in real time for adjustment or shutdown.
