【摘要】：针对热拌混凝土生产过程中物料加热、干燥能耗高等问题,通过实验分析了滚筒内扬料叶片结构参数对料帘分布特性的影响,对滚筒干燥器和料帘进行离散元仿真建模,实现扬料叶片齿间距、宽度、折弯角最优设计,优化计算后得到齿间距为39mm、叶片宽度为40mm、折弯角为128°。构建能耗预测支持向量机模型,能耗预测误差为±5%,实现滚筒干燥过程操作和生产参数的优化。
[Abstract]:In view of the problems of high energy consumption and heating of materials in hot mix concrete production, the influence of the structural parameters of lifting blade on the material curtain distribution characteristics in the drum is analyzed experimentally, and the discrete element simulation model of the drum dryer and curtain is carried out. The optimum design of tooth spacing, width and bending angle of lifting blade is realized. After optimized calculation, the tooth spacing is 39 mm, blade width is 40 mm, and bending angle is 128 掳. The energy consumption prediction support vector machine model is constructed, and the energy consumption prediction error is 卤5, which realizes the optimization of the operation and production parameters of the drum drying process.
