Drying is sent drying cart on the adobe sign indicating number of moulding into the dry kiln drying, and be 18h arid cycle;

Roasting is sent dried adobe into calcining kiln, and calcining kiln is selected the triple channel tunnel type for use, and the roasting mode is based on internal combustion, and external combustion is auxilliary, firing cycle 28h, and waste heat and part cigarette heat are pumped to dry kiln by unit heater respectively and are used for dry brick;

The finished product unloading, the brick product that roasting is good go to the finished product field and pile piled bricks.

The present invention has following beneficial effect:

1) the present invention is that sintered hollow block and big face are right-angled triangle or right-angled trapezium, and proportion is 900-1000kg/m ³, be applicable to the back plug mouthful of building, (proportion is about 1800kg/m with traditional solid brick ³) compare, weight reduction 50-60% not only can reduce brickwork joint, improves construction quality, and helps to improve speed of application;

2) coefficient of thermal conductivity of sintered hollow block of the present invention is 0.25-0.3 w/m ².k, (coefficient of thermal conductivity is 0.54 w/m with traditional solid brick ².k) compare, thermal property of the present invention is obviously improved, and has improved the heat insulating ability of building, has reduced the energy consumption that is used to warm oneself winter, helps energy conservation;

3) voidage of the present invention is 45-50%, compares with traditional solid brick, and the raw material consumption reduces significantly, has not only saved cost of production, and has saved the energy consumption in the manufacturing process;

4) compare with traditional solid brick, the present invention saves coal-fired 50-60%, has not only reduced energy consumption, and reduces CO ₂Discharge value reaches 50-60%, has reduced environment pollution significantly, helps environmental protection.
