Embodiment 1
[0030] A method for preparing high-strength alkali-resistant bricks, comprising a mixing stage, a brick forming stage, a drying stage, a preheating stage, a roasting stage, a heat preservation stage and a cooling stage, and the specific steps are as follows:
[0031] S1: In the mixing stage, the raw materials are fully mixed and stirred according to the predetermined ratio, and humidified after stirring;
[0032] S2: In the adobe forming stage, the stirred and humidified raw materials are molded with a mold to form a block of cuboids to obtain adobe;
[0033] S3: In the drying stage, the bricks are placed on the conveyor belt of the firing kiln, and the bricks are heated by the hot air system of the firing kiln;
[0034] S4: In the preheating stage, the firing exhaust gas from the firing kiln in other firing stages is introduced, and the bricks are preheated in conjunction with the heating system in the firing kiln in the preheating stage. The upper limit of the preheating tem...
