Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste lead-acid battery recycling methods fail to completely separate thin lead grids and lead needles from lead slime, leading to low lead yield rates, high energy consumption, and resource wastage when smelted at low temperatures, and high ash residue and labor intensity when smelted at high temperatures.
Innovation Solution
A separator system comprising a barrel body with corrosion-resistant and wear-resistant balls, a feed device, a bracket device, a discharge device, and a driver, which uses rotating components and flushing water to separate thin lead grids and lead needles from lead slime by grinding and washing, ensuring complete separation and efficient material handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional pyrometallurgy or reverberatory furnace mixing method is used, then the processing can be simplified, but the separation of thin lead grid and lead needle from lead slime is incomplete, leading to low lead yield rate and high energy consumption
Solution Approach 1:
The invention divides the processing into two distinct stages: first stage uses a crusher to perform rough separation of lead grid from battery components, and second stage uses a hydraulic separator to perform precise separation of thin lead grid and lead needle from lead slime. This segmentation allows each stage to be optimized for its specific function, achieving complete separation while maintaining processing efficiency.
Solution Approach 2:
The invention introduces flushing water as an intermediary medium in the hydraulic separator to facilitate the separation process. The flushing water creates a fluid environment that enables density-based separation, allowing thin lead grid and lead needle to be effectively separated from lead slime without direct mechanical contact that could cause damage.
2Use of energy by stationary object
If thin lead grid and lead needle adhered with lead slime are melted directly at low temperature, then energy consumption is reduced, but the lead yield rate is low and ash residue is high
Solution Approach 1:
The invention performs preliminary separation action before melting by using the hydraulic separator to completely remove lead slime from thin lead grid and lead needle. This preliminary action ensures that only clean lead products enter the melting stage, enabling low-temperature melting with high lead yield rate and low ash residue.
3Adaptability or versatility
If crushing and sorting systems are used, then complete sets of equipment can be obtained, but they cannot directly process storage battery with ABS plastic case and require manual classification
Solution Approach 1:
The invention designs the crusher and hydraulic separator to handle multiple types of waste lead-acid batteries including those with ABS plastic cases. The system is configured to automatically process different battery types without requiring manual classification, achieving both versatility and ease of operation.
4Quantity of substance
If separator papers are used in crushing and sorting systems, then components can be sorted, but fine lead scrap and lead slime cannot be completely separated causing secondary pollution and resource waste
Solution Approach 1:
The invention replaces the mechanical separator paper system with a hydraulic separation system that uses water flow and density differences to separate fine lead scrap and lead slime from lead grid. This substitution eliminates the inability of separator papers to completely separate fine particles, preventing secondary pollution and resource waste.
