AI Technical Summary

Technical Problem

Existing tunnel kiln cooling devices can cause cracks in easily cracked materials such as ceramics and glass due to excessive temperature differences during the cooling process, thus affecting material quality.

Method used

A dual-fan system is adopted. The first fan injects cold air into the cooling chamber for cooling, while the second fan injects hot air into the pre-cooling chamber for pre-heating. Combined with a dust removal mechanism, the hot air is dusted and humidified to reduce temperature difference and prevent cracks caused by thermal stress.

Benefits of technology

This achieves a smaller temperature difference between the material surface and interior, reduces thermal stress, prevents easily cracked materials from cracking due to excessive thermal stress during cooling, ensures material quality, and improves cooling efficiency.
