The invention relates to a lime firing kiln. The lime firing kiln comprises a kiln body, and a distributing device, a preheating zone, a calcining zone and a cooling zone are sequentially arranged in the kiln body from top to bottom; the distributing device comprises a distributing device body and a distributing chute arranged at the bottom end of the distributing device body, and the distributing chute comprises an accumulating section and a smooth section which are connected with each other; the accumulating section sequentially comprises a protection plate, a base plate and an accumulating plate from outside to inside, and the accumulating plate is detachably arranged on the base plate; and a plurality of axial protrusions are arranged on the inner surface of the accumulating plate in the axial direction, a plurality of longitudinal protrusions matched with the axial protrusions are arranged at the bottom end of the accumulating plate, and grid grooves are formed between the axial protrusions and the longitudinal protrusions. Through the arrangement of the grid groove, a part of furnace charge can be stored in the grid grooves, secondary impact of the furnace charge falling again on the distributing chute is avoided, the impact pressure of the distribution chute is reduced, and the service life of the distribution chute is prolonged.
本发明涉及一种石灰烧制窑炉，包括炉体，所述炉体内自上向下依次设有布料器、预热带、煅烧带和冷却带；所述布料器包括布料器本体和设置在布料器本体底端的布料溜槽，所述布料溜槽包括相互连接的积窝段和平滑段；所述积窝段从外向内依次包括保护板、基板和积窝板，所述积窝板可拆卸的设置在基板上；所述积窝板内表面沿轴向设有多个轴向凸起，所述积窝板底端处设有多个与轴向凸起匹配的纵向凸起，所述轴向凸起和纵向凸起间形成网格槽。通过网格槽的设置，使得网格槽内会储存一部分炉料，避免再次下落的炉料对布料溜槽的二次冲击，减少布料溜槽的冲击压力，延长布料溜槽的使用寿命。
