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.
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.
