Description

Technical Field

[0001] The utility model relates to the technical field of kiln equipment, in particular to an energy-saving mobile tunnel kiln. Background Art

[0002] Tunnel kiln is a tunnel-like kiln built of refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other transportation vehicles. It is a modern continuous firing thermal equipment.

[0003] During the process of firing porcelain in a tunnel kiln, the existing porcelain is not conducive to stacking. The porcelain is placed into the tunnel kiln in the form of shelves through tracks. The shelves for storing porcelain can only store a fixed number of porcelains, and the plane space of the kiln is limited, making it difficult to stack porcelain again. As a result, there is still empty space in the kiln. Maintaining high temperature in the kiln consumes a lot of energy. If the empty space is not utilized, it will cause great energy waste. For this reason, we propose an energy-saving mobile tunnel kiln. Utility Model Content
