For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0033] As Figures 1-8 shown, the present application provides an electrolyte waste liquid treatment device for lithium battery production, including a baffle 1, a filtration component 2, a separation component 3, a drying component 4, and a circulation component 5. The filtration component 2 is placed on the top of the separation component 3, the drying component 4 is placed at the bottom of the separation component 3, the separation component 3 is communicated with the circulation component 5, the circulation component 5 is communicated with the filtration component 2, and the baffle 1 is detachably connected to the front end of the filtration component 2;

[0034] This structure optimizes the treatment process, enabling the electrolyte waste liquid to pass through filtration, separation, and drying in sequence, improving the treatment efficiency, facilitating the installation, maintenance, and management of each component, and reducing the equipment maintenance cost and time. Similar to the step-by-step treatment of waste liquid in an intelligent adaptive precision filtration system, this reasonable spatial layout provides a strong guarantee for subsequent deep purification and resource recovery.

[0035] The separation component 3 is communicated with the circulation component 5, and the circulation component 5 is communicated with the filtration component 2: realizing the recycling of electrolyte waste liquid treatment, reducing resource waste, improving resource utilization rate, reducing production costs, and at the same time reducing environmental pollution, improving the economy and environmental protection of the device, and conforming to the concept of sustainable development. The baffle 1 is detachably connected to the front end of the filtration component 2, which is convenient for cleaning and replacing the baffle 1, ensuring the filtration effect of the filtration component 2, effectively intercepting large particle impurities, protecting the subsequent filtration component 2, and extending the service life of the equipment. Similar to the preliminary purification function of the outermost high-strength large-aperture stainless steel filter screen in an intelligent adaptive precision filtration system, it provides support for subsequent finer filtration links.

[0036] In the middle of the filtration component 2, there are an initial filtration plate 17, a middle filtration plate 18, and a nanofiltration plate 19 with adjustable angles.

The angles and positions of the filtration plates can be flexibly adjusted according to the particle size and distribution of impurities in the electrolyte waste liquid, precisely filtering impurities of different particle sizes, improving the filtration effect and accuracy, extending the service life of the filtration plates, and reducing the replacement frequency and cost. This is similar to the principle of the ceramic ultrafiltration membrane and the high-precision nanofiltration membrane in the intelligent adaptive precision filtration system automatically adjusting the filtration state according to real-time monitoring data to maintain excellent filtration effects. Both can make adaptive adjustments according to different situations to ensure that the filtration effect is always in the best state.

[0037] The filtration component 2 includes a filtration chamber 13, a plurality of adjustment slides 14, adjustment sliders 16, and adjustment clamping plates 15.

The initial filtration plate 17, the middle filtration plate 18, and the nanofiltration plate 19 are respectively detachably connected to the adjustment clamping plates 15. By the asynchronous lifting of the plurality of adjustment sliders 16, the interval adjustment and angle adjustment of the initial filtration plate 17, the middle filtration plate 18, and the nanofiltration plate 19 are completed.

[0038] This structural design makes the installation, disassembly, and angle adjustment of the filtration plates more convenient, improves the operation flexibility and work efficiency, facilitates the cleaning, replacement, and maintenance of the filtration plates, ensures the long-term stable operation of the filtration component 2, and reduces production stagnation caused by equipment failures. By the asynchronous lifting of the plurality of adjustment sliders 16, the interval adjustment and angle adjustment of the initial filtration plate 17, the middle filtration plate 18, and the nanofiltration plate 19 are completed.

The cleaning drive seat 20 is symmetrical to the top of the filter bin 13, the cleaning drive screw 21 is rotatably connected to the middle of the cleaning drive seat 20, the cleaning main frame 22 is threadedly connected to the cleaning drive screw 21, the cleaning bracket 23 is placed at the bottom of the cleaning main frame 22, the cleaning slider 24 is symmetrically slidably connected to both sides of the cleaning bracket 23, the cleaning shaft 25 is rotatably connected to the cleaning slider 24 and the cleaning support plate 26, the nozzle seats 27 are arranged at intervals on both sides of the cleaning support plate 26, the nozzle rotating plate 28 is hinged to the middle of the nozzle seat 27, the nozzle 29 is installed on the nozzle rotating plate 28, and the rolling brush 30 is rotatably connected to the bottom of the cleaning support plate 26.

[0040] The automatic cleaning function of the primary filter plate 17 realizes rolling cleaning and spraying of cleaning liquid through the cooperation of various components, effectively preventing the filter plate from being blocked, ensuring the filtering effect and efficiency, reducing the labor intensity and time cost of manual cleaning, and reducing the risk of production delays caused by untimely manual cleaning. This is similar to the mechanism in which each membrane component in the intelligent adaptive precision filtration system automatically starts backwashing, chemical cleaning or physical repair procedures based on real-time monitoring data to ensure that the membrane component always maintains excellent filtering effects during long-term operation. Both can realize automated maintenance and cleaning, and improve the operating efficiency and reliability of the equipment.

[0042] The self-repairing ring 32 has a built-in sensing chipset that can dynamically adjust its own structure. When the filter hole 31 is blocked or damaged, it can automatically repair and clear it, thereby improving the filtering stability and service life of the middle filter plate 18, reducing the problem of decreased filtering efficiency and deterioration of the effect caused by the blockage of the filter hole 31, enhancing the reliability and stability of the device, and reducing the equipment maintenance cost. This is the same as the intelligent sensing chipset built into the ceramic ultrafiltration membrane in the intelligent adaptive precision filtration system, which can accurately monitor parameters such as membrane flux and pressure difference, and intelligently and dynamically adjust the structure of the membrane hole 33 to always maintain good filtering performance. Both reflect the intelligent self-repair function to ensure the continuous stability of the filtering effect.

[0043] The nanofiltration plate 19 includes membrane pores 33, backflush brackets 34, backflush sliders 35, backflush support plates 36, backflush seats 37 and backflush heads 38.

The backflush brackets 34 are arranged at the bottom of the nanofiltration plate 19. The backflush sliders 35 are slidably connected to the backflush brackets 34. The backflush support plates 36 are installed in the middle of the backflush sliders 35. The backflush seats 37 are slidably connected to the backflush support plates 36. The backflush heads 38 are installed on the backflush seats 37.

[0044] The backflush cleaning function of the nanofiltration plate 19 realizes the reverse flushing of the membrane pores 33 through the cooperation of various components. The nano-level induction probes monitor the blockage situation in real time and initiate backflushing in a timely manner, effectively preventing the blockage of the membrane pores 33, ensuring the filtration effect and accuracy, improving the service life and working efficiency of the nanofiltration plate 19, and reducing the risks of increased filtration costs and deteriorated effects caused by the blockage of the membrane pores 33. This is similar to the mechanism in the intelligent adaptive precision filtration system where the innermost high-precision nanofiltration membrane is equipped with nano-level induction probes to track the residual impurities in the sewage in real time and accurately capture them, and at the same time automatically start corresponding programs according to the real-time monitoring data to maintain the filtration effect. Both utilize advanced monitoring and cleaning technologies to ensure the efficient operation and long-term stability of the nanofiltration membrane.

The nano defoaming net 47 is detachably connected to the top of the electrocoagulation reaction tank 39.

[0046] The layout with the electrocoagulation flocculation reaction tank 39 placed on top of the super-vortex flow chamber 40 enables impurities to first form flocs in the electrocoagulation flocculation reaction tank 39 and then be separated by centrifugal force in the super-vortex flow chamber 40.

[0048] The structural design of the super-vortex separator 8 enables the sewage to form a high-speed rotating centrifugal force field therein. The double-helix blade 52 stirs and guides the solid-liquid separation, improving the separation effect and efficiency. The separation process is more stable and reliable, reducing the impurity content in the separated liquid, improving the recovery quality and utilization rate of the electrolyte, and providing a purer raw material for the subsequent treatment process.
