Resin Curing Device Bypass Passage for Heater Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin curing devices using batch processing methods suffer from inefficiencies due to heat loss and the need to reheat the curing furnace between cycles, leading to prolonged curing times and increased maintenance costs from varnish liquefaction and attachment to heater components.
Innovation Solution
A resin curing device with a circulation passage system that allows heated gas to be circulated between a blower, heater, and curing furnace via a bypass passage, enabling quick temperature recovery and preventing varnish liquefaction by switching between circulation and bypass passages based on operational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batch processing method is used to cure liquid resin, then the curing process can be completed, but the heater must be stopped and reheated between cycles, leading to time loss and reduced productivity
Solution Approach 1:
The bypass passage allows the heater to continue heating air in advance during the unloading/loading phase, so that when the next curing cycle begins, the air is already heated and ready to be circulated into the curing furnace, eliminating the reheating wait time
Solution Approach 2:
The heater operates continuously without stopping between curing cycles by using the bypass passage to circulate air through the heater even when the curing furnace is being opened/closed, maintaining continuous heat generation and avoiding energy loss from cooling and reheating
2Speed
If the heater temperature is maintained high continuously, then quick temperature recovery is achieved, but energy consumption increases
Solution Approach 1:
The system dynamically switches between two operational modes: during curing, hot air is circulated through the curing furnace; during unloading/loading, hot air is circulated through the bypass passage. This dynamic switching allows the heater to maintain temperature without continuously heating the curing furnace when it is open, reducing energy waste
3Ease of operation
If the curing furnace temperature decreases during unloading/loading, then air can be exchanged, but the heated air escapes and the heater temperature drops, requiring reheating time
Solution Approach 1:
The air circulation path is segmented into two separate routes: the circulation passage that goes through the curing furnace for curing operations, and the bypass passage that goes around the curing furnace for temperature maintenance during unloading/loading. This segmentation allows independent control of each function
