概述：

    往復(fù)式出灰機(jī)又稱托板出灰機(jī)，主體為一對對稱分部的篦板小車，通過傳動裝置沿固定軌道作往復(fù)運動，托動成品石灰落入爐底料斗內(nèi)。這種出灰機(jī)結(jié)構(gòu)簡單、重量輕、容易制造：但其出灰均勻性差，托板兩側(cè)易造成死角，調(diào)解不及時時，易造成焙燒帶傾斜，對下來的粘結(jié)料塊起不到破碎作用，且托板箱體面積較大，不易密封，容易造成底部漏風(fēng)而影響爐內(nèi)氣流分部和環(huán)境污染。    

在70年代設(shè)計和建造的石灰窯中，相當(dāng)一部分使用這種出灰設(shè)備，因后期維護(hù)和保養(yǎng)較為復(fù)雜，故障率高，需要人工多注意設(shè)備狀態(tài)。

目前國內(nèi)石灰窯已經(jīng)基本不選擇該類設(shè)備。

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.
