The utility model is designed to provide a kind of simple structure, low cost, energy conservation and environmental protection of fire building brick mobile tunnel kiln.
To accomplish this, the utility model provides the fire building brick mobile tunnel kiln, including fixed annular furnace bottom and round with kiln bottom concentric circular activities kiln body, kiln body bottom through wheel supports in kiln bottom on either side of the circular orbit, kiln body for whole continuous cavity, outslde top mounted have hot air duct, hot air duct of string containing machine, hot air duct front-end from two side have drawn tubes and kiln body air preheating segment of the lumen interlinked, hot air duct back-end drawn from two side have convulsions tubes and kiln body cooling section of the lumen is same.
Kiln body for whole continuous cavity, kiln body in circular orbit continuous moving slowly when ordinal of brick-drying complete preheating, baking, heat preservation and the cooling process, in this process, thus without stop kiln body also don't need in kiln body of the front end and preheating, baking, insulation and cooling section between setting spake, and simplifies the structure and improve the production efficiency. Convulsions tubes from air cooling section, the fan out by hot air duct to supply tubes, by air supply tubes send into kiln body is preheated period inside, such can save energy and environmental protection, hot air piping layout in outslde, structures are relatively simple, more facilitate installation maintenance.
The utility model has the technical effect is: simple structure, low cost, high production efficiency, energy-saving and environmental protection
