Solution Overview
Problem
Conventional cooling methods for honeycomb structured bodies during firing are inefficient, requiring a long time and being adversely influenced by external temperatures, which limits manufacturing efficiency and can cause thermal impacts leading to cracks.
Innovation Solution
A cooling apparatus with multiple blowers and a suction mechanism is used to efficiently cool ceramic fired bodies within a firing jig, allowing for indirect cooling and reducing exposure to direct air flows, thereby shortening cooling time and preventing thermal damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If natural radiation cooling is used for honeycomb fired bodies, then the cooling process is simple, but the cooling time is long and manufacturing efficiency is limited
Solution Approach 1:
The patent applies pneumatic cooling by introducing air flows into the firing jig to cool the honeycomb fired body. Multiple air inlets are provided at different positions (front, rear, left, right sides) to create comprehensive air circulation that rapidly removes heat from the fired body, replacing the slow natural radiation cooling process with efficient forced convection cooling.
2Device complexity
If natural radiation cooling is used, then no additional cooling equipment is needed, but external temperature adversely influences the cooling process
Solution Approach 1:
The patent uses air as a controlled cooling medium introduced through the firing jig structure. The air flow system creates a controlled cooling environment that isolates the cooling process from external temperature variations. The multiple air inlets and the firing jig design ensure consistent cooling regardless of ambient conditions, improving reliability.
3Productivity
If direct air flow cooling is applied, then cooling speed increases, but thermal impact may cause cracks in the fired body
Solution Approach 1:
The cooling system is segmented into multiple air inlets positioned at different locations (front, rear, left, right sides) of the firing jig. This segmentation allows air to be introduced from multiple directions simultaneously, distributing the cooling load and reducing localized thermal shock that could cause cracking, while maintaining high overall cooling efficiency.
Solution Approach 2:
The firing jig acts as an intermediary between the external air flow and the honeycomb fired body. Air flows through the firing jig structure rather than directly impacting the fired body, which mediates the thermal impact and prevents sudden temperature changes that could cause cracks, while still achieving rapid cooling through the jig walls and structure.
