摘要: 针对某烟厂SJ1237型叶丝加料机工作过程中滚筒内热风温度波动超过工艺要求问题,从改进滤网清吹系统,提高压缩空气压力,优化滤网清吹、排潮、蒸汽喷吹程序等方面,改进设计了叶丝加料机热风控制系统.运行效果证明:改进后热风温度可控制在(100±2)℃,热风温度过程能力指数提升至1.96,出口水分标准偏差降为0.13%,筒体内粘附物料量降为1.9kg/d,可达到稳定叶丝加料机热风温度的目的.Abstract: In order to solve the problem that the hot-air temperature fluctuations of SJ1237 cut tobacco casing cylinder in certain cigarette factory is over technology assessment requirements, the hot-air temperature control system of cut tobacco casing sylinder was improved to improve the compressed air pressure, optimize screen cleaning, moisture removal and steam injection. The operation result showed that hot-air temperature (100±2)℃,process capability index of hot-air temperature was raised to 1.96, standard deviation of outlet waterwas decreased to 0.13%, the amount of material adhered in cylinder body reduced to 1.9 kg/d. It reached the purpose of stabilizing hot-air temperature.
