Electrode Plate Drying Furnace With Uniform Hot-Air Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode plate drying furnaces face issues with uneven distribution of hot air, leading to poor electrode plate quality and safety risks due to non-uniform drying and potential hot air contact before sufficient flow is established.
Innovation Solution
The electrode plate drying furnace incorporates a supply pipe, drying duct, nozzles, distribution plate, and distribution plate auxiliary apparatus to uniformly distribute fluid across the electrode substrate, preventing air trapping and uneven drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distance between the bottom nozzle and the electrode plate is reduced to increase drying efficiency, then drying efficiency is improved, but hot air contacts the electrode plate before sufficient flow is established causing uneven drying
Solution Approach 1:
The single nozzle is divided into multiple nozzles arranged in an array, allowing the fluid flow to be segmented into multiple streams that distribute more evenly across the electrode plate surface, preventing localized overheating and ensuring uniform drying while maintaining close proximity for high efficiency
Solution Approach 2:
A distribution plate is introduced as an intermediary component between the nozzle array and the electrode plate, which further distributes the fluid flow evenly across the plate surface, ensuring that sufficient flow reaches all areas before contact with the electrode plate
2Productivity
If hot air is supplied into the electrode plate drying furnace, then drying process is activated, but air does not uniformly distribute throughout the bottom nozzle remaining biased toward the air introduction area
Solution Approach 1:
The single air supply path is segmented into multiple nozzles with multiple holes each, creating multiple independent flow channels that distribute air more uniformly across the electrode plate, eliminating the bias toward the air introduction area
Solution Approach 2:
Each nozzle is designed with specific local characteristics (multiple holes, specific orientations) to optimize the local distribution of hot air, ensuring that each region of the electrode plate receives appropriate airflow for uniform drying
