摘要
本文就一种新型干燥设备——盘式干燥器的性能进行了理论分析和实验研究。文中主要探讨了散状物料在干燥盘上的分布与运动规律。通过对砂子的冷模实验和理论分析，得出了物料在干燥盘上停滞时间与参变量的关系，得出了耙叶推动物料所耗功率与参变量的关系，参变量的物料性能、耙叶几何参数、转速等，为工业上实际应用提供了参考数据。还得出了干燥盘上耙叶几何尺寸及角度的设计方法，得出了物料运动轨迹的方程，比较了有物料时和无物料时设备所耗功率的差异，并对实验现象进行了分析。
In this paper,the performance of a new type of drying equipment-plate dryer is studied.The distributive and motive law of the product are probed in this paper.By the cold model experiments and theoretical analysis of sand,the relationship between the retention time and the variable parameter is obtained,the relationship between the consumed power of raking product and the variable parameter is obtained.The variable parameters are the characteristics of product,the geometric parameter of the plows and angle velocity etc.These provided a good basis for industrial and practical applications.The method of design on geometric dimensions and angles of the plow on the drying plate is obtained,the equation of motive locus of the product is obtained.The consumed power of the equipment,and the experimental phenmenon has been analysed.
