Description

Technical Field

[0001] The present application relates to the technical field of battery recycling, and particularly to an intelligent integrated complete set of systems and methods for recycling waste lithium batteries. Background Art

[0002] With the popularization and development of new energy vehicles, the loading volume of lithium batteries has increased significantly. However, the large-scale use and retirement of lithium batteries have also brought corresponding resource and environmental problems.

[0003] 1. There are many limitations in the existing pre-discharge pretreatment of waste lithium batteries. The crushing equipment has poor compatibility and is flammable and explosive during the process.

[0004] There are certain disadvantages and limitations in the existing disposal process. The existing pre-discharge pretreatment of waste lithium batteries uses brine to discharge to avoid combustion and explosion caused by battery short circuit during the crushing process. However, there are many limitations such as low discharge efficiency, long processing time, high cost, and potential safety hazards. In addition, there are various models and types of waste lithium batteries, and the crushing and sorting system cannot be well matched, resulting in the intermixing of copper and aluminum in the sorted products, increasing the cost of impurity removal, and increasing the probability of accidents such as overflow in the subsequent wet end. At the same time, pollutants such as dust and organic volatile components generated during the crushing process also bring pressure to the environment. Therefore, there is an urgent need to develop a technology of pre-discharge pretreatment-free - direct crushing - separation to reduce the process links of waste lithium battery recycling and improve the safety, stability, and automation of the system.

[0005] 2. The pyrolysis of the disassembled materials has high energy consumption, the pyrolysis products are difficult to treat, and the recovery rate of electrode materials is low.

[0006] The electrolyte and binder in the disassembled waste lithium batteries cause the current collector to adhere to the electrode material, affecting the recovery rate of the electrode material. Although direct fuel heating can remove the binder, there is a lack of in-depth theoretical research on the pyrolysis process. Its resistance heating has problems such as high energy consumption and uneven heating, resulting in incomplete removal of organic matter and increasing the difficulty of subsequent metal extraction. Therefore, there is an urgent need to develop a new pyrolysis process to achieve uniform and rapid heating of materials, improve the efficiency of organic matter removal. At the same time, it is necessary to comprehensively apply various technical means for waste gas control and treatment to realize the resource utilization of waste gas and promote the green and sustainable development of the retired power battery recycling industry.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0028] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0029] In an exemplary embodiment, as Figure 1 shown, an intelligent integrated complete set of waste lithium battery recycling systems is provided. The intelligent integrated complete set of waste lithium battery recycling systems includes: a data acquisition module (not shown in the figure), a charged disassembly and crushing module, an electromagnetic self-heating pyrolysis module, an automated intelligent sorting module, and a pollutant harmless treatment module.

[0030] The data acquisition module includes: a temperature sensor and an oxygen content sensor, which are used to collect the temperature and oxygen content distribution data in the crusher and the pyrolysis furnace cavity at multiple points, and send the collected temperature and oxygen content distribution data in the crusher cavity to the charged disassembly and crushing module, and send the collected temperature and oxygen content distribution data in the pyrolysis furnace cavity to the electromagnetic self-heating pyrolysis module.

[0031] The charged disassembly and crushing module is used to perform real-time adjustment and control on the crusher according to the temperature and oxygen content distribution data in the crusher cavity to obtain crushed materials.

[0032] The electromagnetic self-heating pyrolysis module is used to perform pyrolysis operations on the crushed materials according to the temperature and oxygen content distribution data in the pyrolysis furnace cavity to obtain pyrolyzed crushed materials.

[0033] The automated intelligent sorting module is used to perform intelligent sorting on the pyrolyzed crushed materials to obtain product black powder, copper particles, and aluminum particles with a purity higher than a preset purity.

[0034] The pollutant harmless treatment module is used to treat the dust and waste gas generated by the charged disassembly and crushing module, the electromagnetic self-heating pyrolysis module, and the automated intelligent sorting module.

[0039] The charged disassembly and crushing module performs real-time adjustment and control on the crusher according to the collected temperature and oxygen content distribution data in the crusher cavity; used lithium batteries are loaded into the crusher, and for the crusher in a closed state, a vacuum pumping device is used to perform a vacuum pumping process on it. When it is detected that the air pressure in the crusher reaches 0.2 Bar, nitrogen is filled into the crusher until the oxygen content sensor feedbacks that the oxygen content is 3%, and then the crusher starts crushing to achieve the crushing and separation of the positive and negative electrode plates, connection terminals, and outer casing of the used lithium battery.

[0040] As an alternative embodiment, the electromagnetic self-heating pyrolysis module includes the following devices.

[0041] A second nitrogen filling unit for filling nitrogen into the pyrolysis furnace cavity.

The temperature data is feedback by the temperature sensor, and the operating temperature is controlled to self-heat run at 100°C - 400°C for 1h - 3h to completely decompose the binder and electrolyte of the waste lithium battery.

High-purity product black powder, copper particles, and aluminum particles are obtained through the automated intelligent sorting module. The materials first enter the multi-layer linear screen for pre-screening operations. The oversize materials larger than 3mm enter the Z-shaped sorter for sorting operations to obtain various products such as copper heads, aluminum foils, and stainless steels. The remaining copper and aluminum foils are combined with the screening materials of 100 meshes - 3mm and enter the dry stripping machine for pole piece powder for separation and black powder particle size refinement. After screening the refined materials with a 100-mesh linear screen, finished black powder is obtained.
