The invention discloses a calcining kiln for manufacturing cement clinker and a calcining cooling method, and relates to the technical field of calcining cooling of cement clinker. The rotary kiln comprises a rotary cylinder, a kiln head box and a kiln tail box, a preheating box and a preheating pipe are arranged in the kiln head box, a material receiving disc and a heat dissipation scraping plate are arranged in the kiln tail box, and meanwhile the kiln tail box and the kiln head box are communicated with each other through a recycling pipe. The preheating box and the preheating pipe are arranged, and raw materials are preheated through air waste heat generated after heat radiation in the kiln tail box, so that raw material powder is heated faster, and calcination is cheaper; by arranging the pneumatic trough plate, the material receiving disc is driven to rotate by utilizing the power for driving the air pump to pump cooling air, the stacked clinker is screened after being flattened for heat dissipation, the heat dissipation area is enlarged, and the cooling speed is increased; meanwhile, the air participating in cooling work participates in preheating work of the raw materials again after being heated, and cyclic utilization of energy and heat in the calcining kiln is completed.
本发明公开了一种用于制造水泥熟料的煅烧窑及煅烧冷却方法，涉及水泥熟料煅烧冷却技术领域。本发明包括回转筒、窑头箱和窑尾箱，窑头箱内设预热箱和预热管，窑尾箱内设接料盘和散热刮板，同时窑尾箱与窑头箱之间通过设置回收管相互连通。本发明通过设置预热箱和预热管，利用窑尾箱中热辐射后的空气余热对原料进行预热，使原料粉末升温更快，煅烧更便宜；通过设置气动槽板，利用驱动气泵抽送冷却空气的动力带动接料盘旋转，将堆积的熟料摊平散热后筛滤，扩大散热面积，提高冷却速度；同时参与冷却工作的空气升温后再次参与原料的预热工作，完成了煅烧窑内部的能源与热量的循环利用。
