Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrode drying technologies fail to prevent over-drying during the initial drying section, leading to electrode cracking and contamination within the drying furnace.
Innovation Solution
An electrode drying system that calculates the residual quantity of heat in the drying furnace during immobility times using pre-calculated drying control data, and adjusts the heat supply by subtracting the residual heat from the common heat quantity to prevent over-drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electrode sheet is supplied into the oven after a time interval during which residual heat accumulates, then the drying process can be maintained continuously, but cracks and wrinkles are generated on the electrode during the initial drying section due to excessive heat
Solution Approach 1:
The system performs preliminary calculation of residual heat quantity in the drying furnace before the electrode sheet is supplied. The control part uses this calculated residual heat information to adjust the heat supply amount in advance, preventing excessive heat accumulation that would cause cracking and wrinkles on the electrode surface during initial drying.
Solution Approach 2:
The system implements a feedback control mechanism where the control part continuously monitors the residual heat quantity in the drying furnace and adjusts the heat supply amount based on this feedback. When residual heat is detected, the heat supply is reduced accordingly, maintaining optimal drying conditions and preventing electrode damage while ensuring continuous production.
2Productivity
If a common quantity of heat is supplied to the drying furnace without considering residual heat, then the drying efficiency is maximized, but over-drying occurs in the initial drying section causing electrode cracking and powder generation
Solution Approach 1:
The system dynamically changes the heat supply parameter based on the residual heat condition in the drying furnace. Instead of using a fixed common quantity of heat, the control part adjusts the heat supply amount according to the calculated residual heat quantity, optimizing the drying process to prevent over-drying and electrode damage while maintaining high drying efficiency.
Solution Approach 2:
The control part calculates the residual heat quantity in advance before the electrode enters the drying furnace and uses this information to pre-adjust the heat supply amount. This preliminary action prevents excessive heat input that would cause over-drying, cracking, and electrode powder generation, while still maintaining efficient drying operation.
