Furnace With Counterflow Cooling Gas for Gentle Goods Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furnaces struggle to gently and uniformly subject delicate goods to temperature while maintaining a specific furnace atmosphere, as they often expose goods to harsh conditions and uncontrollable atmospheres.
Innovation Solution
A furnace design with cooling gas conveyed in counterflow to the transport direction, combined with a controlled furnace atmosphere, ensures gentle temperature treatment by using heating means and transport rollers to manage temperature and gas flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heating means are used to subject goods to temperature, then the goods can be temperature-treated, but the treatment is harsh and not gentle enough for delicate goods
Solution Approach 1:
The patent introduces cooling gas as an intermediary substance between the heating means and the delicate goods. The cooling gas absorbs excess heat and delivers it gradually to the goods through controlled convection, mediating the temperature transfer to make it gentler and more uniform. This resolves the contradiction by allowing temperature treatment while eliminating harsh direct heating exposure.
Solution Approach 2:
The patent changes the thermal parameters of the treatment environment by introducing a cooling gas flow that modifies the temperature profile. Instead of direct high-temperature exposure, the goods experience a moderated temperature curve through the cooling gas intermediary, transforming the harsh temperature parameter into a gentler treatment parameter.
2Stability of the object's composition
If conventional furnaces are used for temperature treatment, then goods can be heated, but the furnace atmosphere cannot be controlled specifically for delicate goods
Solution Approach 1:
The patent segments the gas flow system into separate cooling gas supply and furnace atmosphere control pathways. The cooling gas can be supplied independently with specific composition requirements, while the furnace atmosphere is controlled separately through the heating means environment. This segmentation allows both specific atmosphere control and compositional flexibility to coexist.
Solution Approach 2:
The cooling gas serving means performs multiple functions: it cools the goods, controls the furnace atmosphere composition, and provides a medium for gentle heat transfer. This multi-functionality allows the system to maintain stable furnace atmosphere while adapting to different gas composition requirements for various delicate goods.
3Productivity
If goods are transported through the furnace chamber, then continuous treatment is possible, but the goods are exposed to uncontrolled atmosphere and harsh conditions
Solution Approach 1:
The cooling gas acts as a protective intermediary throughout the transport process. As goods move continuously through the furnace chamber, the cooling gas continuously surrounds and protects them, filtering out harsh conditions and uncontrolled atmosphere elements while maintaining gentle temperature treatment throughout the entire transport path.
Solution Approach 2:
The cooling gas supply operates continuously throughout the goods' transport through the furnace chamber, providing uninterrupted protection and gentle cooling. This continuous action ensures that at no point during the productive continuous treatment process are the goods exposed to uncontrolled atmosphere or harsh conditions.
