Fully automatic clay brick tunnel dryer chamber
Drying and firing system
Drying and firing will adopt two times stacking & firing process with tunnel dryer technology. Drying chamber adopts tunnel dryer (83.65x22.625m). The heat of the dryer comes from high temperature heat of fired-products and residual heat from Tunnel Kiln, through change the system to adjust the feeding air temperature and volume, so that to ensure the drying quality of green bricks.
Tunnel kiln adopts large section with inner width of 6.6 meter, it is designed as a flat ceiling structure. This kiln is suitable for firing products with 1200KJ/Kg characteristics.
Tunnel kiln has smoke exhausting system, kiln cart heat releasing system, kiln cart cooling system, gas burning system, heat recovery system, rapid cooling system and back pressure system(pressure balancing system). This kiln has following features: large section, high capacity, small section temperature difference low, good heat maintain. Meanwhile, the kiln auto-control system can ensure the baking heat parameters are stable.
Drying chamber of system & construction
Drying chamber adopts tunnel dryer (83.65x22.625m). The high temperature fan and low temperature fan of Tunnel Kiln is able to recycle and collect the residual Tunnel Kiln heat and transferred to Dryer, it goes via the heating fan in the dryer beginning to rotating fan, then goes into dryer and bricks through mechanical properties. Moisture will be removed by moisture exhaust fan, so as to ensure the drying quality of green bricks. Well-dried bricks will be unloaded from drying cart by unloading system and re-stacking on the marshalling transfer bench, then the well-dried bricks will be stacked on the kiln cart by stacking machine and sent to tunnel kiln by ferry car.
The heat source of drying chamber is the waste heat from tunnel kiln, which will be supplied to drying chamber through external pipe system. The drying chamber includes airing system, moisture exhausting system, operation system and monitoring system, besides the monitoring system, the airing and exhausting system are made of metal pipe and related fans.
