Solution Overview
Problem
Conventional methods for removing metal impurities from solid-liquid mixtures used in electronic devices, such as lithium-ion batteries, are inadequate, particularly for nonmagnetic metals, leading to insufficient treatment rates and potential short circuits due to unresolved impurities.
Innovation Solution
An impurity processing device and method involving a pipe with insulated first and second electrodes through which a treated liquid containing metal impurities flows, with a power supply generating a current to ionize and miniaturize the impurities, allowing for their removal or deposition on the electrodes, effectively treating both magnetic and nonmagnetic metals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic removal method is used, then magnetic metal impurities can be removed, but nonmagnetic metal impurities cannot be removed
Solution Approach 1:
The patent changes the physical principle from magnetic field interaction to electrical field interaction by applying voltage between electrodes. This parameter change enables the removal of both magnetic and nonmagnetic metal impurities through electrostatic attraction, expanding the适用范围 while maintaining effective impurity removal.
2Productivity
If conventional magnetic removal method is used, then the process is simple, but the treatment rate of impurities is insufficient
Solution Approach 1:
The patent replaces the mechanical magnetic separation process with an electrical field-based electrostatic removal system. By substituting the mechanical magnetic attraction mechanism with electrical field forces between electrodes, the treatment rate increases significantly while the device structure remains relatively simple.
3Productivity
If metal impurities remain in the treated liquid, then the liquid can be used, but short circuits may occur in electronic devices
Solution Approach 1:
The patent extracts metal impurities from the treated liquid by attracting them to oppositely charged electrodes through electrostatic forces. This extraction process removes harmful metal particles that could cause short circuits, allowing the treated liquid to be safely used in electronic device manufacturing while maintaining continuous processing capability.
