Differentiated Waste Battery Crushing for Cleaner Material Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste battery recycling methods face inefficiencies due to the mixing of materials during crushing and grinding, leading to increased difficulty in post-recycling processes and low recycling efficiency, as whole batteries are processed without differentiation between external shells and internal electrode sheets.
Innovation Solution
An orderly differentiated recycling and processing apparatus featuring crushing cavities with rotating rollers and cutting modules using spirally arranged blades, along with a screen assembly, to separate and process waste batteries into distinct components like cathode bars and electrolytes, enhancing the sorting and classification of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If whole waste batteries are directly fed into a crushing and grinding apparatus for processing, then the processing can be completed in a single step, but the slag after grinding mixes with wastes of many materials, increasing the difficulty of post recycling
Solution Approach 1:
The patent applies segmentation by dividing the waste battery recycling process into distinct stages: first cutting the external shell, then crushing the internal electrode sheets. This is achieved through separate cutting modules and crushing modules that process different components independently, preventing material mixing and facilitating targeted recycling of each component type.
Solution Approach 2:
The patent implements preliminary action by performing cutting operations before crushing operations. The external shell is cut and separated first, then the internal electrode sheets are crushed separately. This preliminary separation enables subsequent recycling processes to handle each material type independently, reducing post-recycling complexity.
2Speed
If rough crushing is performed in a disorderly manner, then the crushing process can be completed quickly, but the amount of crushing increases, resulting in low recycling efficiency
Solution Approach 1:
The patent segments the crushing operation into targeted crushing of internal electrode sheets after external shell removal. This prevents unnecessary crushing of already-separated materials and reduces overall crushing volume, thereby improving recycling efficiency while maintaining processing speed through specialized crushing modules.
Solution Approach 2:
The patent applies local quality by providing different processing treatments to different parts of the waste battery: cutting modules for the external shell and crushing modules for the internal electrode sheets. This localized processing approach optimizes each operation for its specific material type, improving both speed and recycling efficiency.
