清洁化纤纺丝熔体熔融输送系统的方法
摘要：
本发明公开了一种能彻底清除化纤纺丝熔体熔融输送系统中的沉积物并节约原料的清洁化纤纺丝熔体熔融输送系统的方法，首先，化纤纺丝熔体熔融输送系统正式排料，当与每个计量泵分别相连的输送管道中均有熔体正常流出后，关闭纺丝料仓下方的闸板阀，然后向螺杆机上方的加料管内的余料中加水0.1~5L，加水时间控制在0.5~2分钟内，当含水的原料进入螺杆机的计量段后，再向螺杆机内加入1~5kg原料，当该原料进入到螺杆机压缩熔融段时，化纤纺丝熔体熔融输送系统停机，并保持停机状态10~60分钟，然后在螺杆机不进料的情况下，重新启动化纤纺丝熔体熔融输送系统，将整个化纤纺丝熔体熔融输送系统中的熔体全部排出。
摘要（英）：

The invention discloses a method for a chemical fiber melt melting system, which is capable of thoroughly cleaning sediments in the chemical fiber melt melting conveying system and saving raw materials. The method comprises the steps of: normally discharging through the chemical fiber melt melting conveying system, when melts in conveying pipes respectively connected with each metering pump normally flow out, closing a gate valve below a spinning bin, then adding 0.1-5L of water in remained materials in a feeding pipe above a screw machine, controlling the water adding time to be within 0.5-2min, when the raw materials containing water enter a metering section of the screw machine, adding 1-5kg of raw materials in the screw machine, when the raw materials enter a compression melting section of the screw machine, halting the chemical fiber melt melting conveying system, keeping the halting state for 10-60min, and then under the condition that the raw materials are fed in the screw machine, re-starting the chemical fiber melt melting conveying system and fully discharging the melts in the whole chemical fiber melt melting conveying system.
