概述：

    往复式出灰机又称托板出灰机，主体为一对对称分部的篦板小车，通过传动装置沿固定轨道作往复运动，托动成品石灰落入炉底料斗内。这种出灰机结构简单、重量轻、容易制造：但其出灰均匀性差，托板两侧易造成死角，调解不及时时，易造成焙烧带倾斜，对下来的粘结料块起不到破碎作用，且托板箱体面积较大，不易密封，容易造成底部漏风而影响炉内气流分部和环境污染。    

在70年代设计和建造的石灰窑中，相当一部分使用这种出灰设备，因后期维护和保养较为复杂，故障率高，需要人工多注意设备状态。

目前国内石灰窑已经基本不选择该类设备。

summary:

    The reciprocating ash removing machine is also called a pallet ash removing machine, and the main body is a pair of symmetrical sections of a grid plate trolley, which are moved by the transmission device along the fixed track for reciprocating motion, and the finished product lime is dropped into the bottom hopper. The ash machine has the advantages of simple structure, light weight, easy to manufacture, but the ash uniformity is poor, both sides of the supporting plate are easy to cause the dead, not always easy to cause the mediation, roasting zone tilt, the crushing effect on bond material block down, and the pallet box area is larger, not easy to seal, easy to cause and effect of furnace the air flow in the division of environmental pollution and air leakage at the bottom.    

   In 70s lime kiln design and construction, a considerable part of the ash discharging device, due to the late maintenance and maintenance is more complex, high failure rate, need to pay more attention to the artificial condition.

   At present, the domestic lime kiln has basically does not choose the type of equipment.
