[0002] In the production process of aerated concrete block, steam curing is a key link to determine the strength and performance of the product. The traditional steam curing equipment has many problems in practical application. On the one hand, the opening and closing of the curing tank depend on manual operation or simple mechanical driving, which not only has high labor intensity and low efficiency, but also causes part wear due to uneven stress during the opening and closing process. On the other hand, the condensate water generated during the curing process cannot be effectively recycled, water resources are wasted seriously, and the excess steam also lacks a reasonable recycling or discharge control mechanism, further increasing the production energy consumption. Therefore, we propose a new steam curing equipment for aerated concrete block production. SUMMARY
