摘要
为了准确计算刮板放焦机的电机功率,利用粉体力学的浅仓贮料压力公式(朗金公式),对刮板所受的物料压力及物料对托焦板料槽壁的侧压力进行了计算,求出了刮板所受总力,进而结合电机功率的相应公式,计算出刮板放焦机2个电机所需的电机功率,经实例计算分别为1.7 k W、3.7 k W,解决刮板放焦机电机性能过剩的问题。
In order to accurately calculate motor power of the scraper coke machine, using the shallow warehouse storage pressure formula of powders mechanics （Rankine formula）, pressure on scraper suffered by material and material pressure on the side wall of the trough are calculated. The total force of the scraper is calculated , and combining with the corresponding motor power formula, the required motor powers of tbe scraper coke machine＇s two motors are calculated. The calculation of examples are 1.7 kW,3.7 kW respectively.The purpose is to solve surplus motor performance of the scraper coke machine.
