Description

一种无风式纺丝冷却成形工艺、装置及纺丝设备 技术领域
本发明属于化学纤维纺丝成形技术领域，具体涉及一种颠覆传统利用冷却风冷却成形方式，改为采用无风冷却成形方式的冷却成形方法、冷却成形装置及纺丝设备。
 背景技术
熔融纺丝纤维成形过程的冷却条件，是影响纤维成形和质量的主要因素之一。它直接关系到纤维结构形态、性能和质量。要获得可纺性与欠伸性能良好的纤维，在纺丝流程中，纤维尚未完全固化之前，从喷丝板至下面约1.2米的区段中的冷却显得尤为重要。在纺丝过程中熔融体出喷丝板孔，进入丝仓空气介质中，熔体温度约在268°C左右，熔体热量经过辐射，传导，对流而散发逐渐冷却凝固成形。当其周围空气介质温度湿度气流波动变化不正常，纤维成形处于非稳定状态之中则影响其温度梯度，速度梯度、直径梯度的变化不稳，纤维成形的固化点位置时高时低，造成初生纤维长链分子的取向度，结晶度，纤维皮层与内芯结构的差异，以及影响纤维外形形态结构出现不规整或异形状态等。此种不稳定纺丝，最终反映于纤维可欠性差，内在质量低，纤维的支数，伸长，强力等不匀率大，染色不均匀。后道工序加工困难，欠伸毛丝断头多，劳动强度高，产量低等。
目前纺丝行业的冷却成形过程基本采用侧吹风或环吹风，对丝束进行冷却定型。如说明书附图1所示，熔融的化纤从喷丝板依次进入膨化区、冷却区、成形区、上油点、形成丝束卷绕后进入下道工艺（织造、清洗）。其工艺过程为：化纤熔融体由挤压机从纺丝箱、喷丝板挤出丝束经过无风区进行膨化，采用大功率制冷设备产生的冷风来进行冷却、成形，再进入上油点进行上油。上油剂的目的是防静电、促进多根抱合与增加平滑性。上油点设置上油轮或喷嘴，以上油轮举例，上油轮在装有纺丝油剂的油槽内旋转，丝束与上油轮接触后附着纺丝油剂。
这种工艺对冷却设备要求较高，一般采用工业空调，每个工位需要3.5kw的功耗，工业空调产生的冷风必须恒温、恒湿、恒速、高洁净。中国专利CN202101383U 纺丝冷却空调、CN103884060A 一种纺丝空调系统及纺丝送风压力稳定切换方法、CN2615607Y 纺丝用高压空调机组、CN104197486A 一种纺丝空调机组侧吹风稳定保护装置、CN204176823U 纺丝机和纺丝车间空调通风系统，都对这种工艺方式及工业空调的特性进行了介绍。
 技术问题
传统纺丝工艺的缺陷如下：
1、由于风冷过程中需冷却的丝会因吹风出现抖动，影响了丝的品质；
2、工作过程中耗能较大，不利于创建低碳社会及降低制造成本；
3、工业空调采购成本高昂，维护成本也较高。
 技术解决方案

熔融体经过喷丝板形成丝条，膨化后进入雾区冷却，
将纺丝油剂与水按照一定比例混合后，进入雾化装置，形成冷却雾，冷却雾对丝条进行降温，
冷却雾同时使纺丝油剂附着在丝条上，对丝条进行上油，
丝条冷却、成形后形成丝束，进入下道工艺。
进一步地，还包括对含有纺丝油剂液体的回收步骤，为了方便收集，雾区位于半封闭腔体内，收集后的纺丝油剂液体废弃或处理后循环使用。
进一步地，根据化纤丝条成型特性，雾区冷却分为多段进行，雾化装置通过雾口向雾区输送冷却雾，每段的雾口数量与大小根据成形工艺要求有所区别。
进一步地，为了适应极寒与炎热地区的工作状况，还包括纺丝油剂水溶液的温度调节步骤，在进入雾化装置前，或在雾化装置内，对纺丝油剂水溶液进行温度调节。
相应地，公开一种无风式纺丝冷却成形装置，采用上述纺丝冷却成形工艺，包括雾化液容器、雾化发生器、雾箱、集油组件，
所述雾化发生器位于纺丝箱体下方，雾化发生器与雾化液容器连接，纺丝油剂与水在雾化液容器内混合；
雾箱呈锥筒状，上部和底部开口，熔融、喷丝后的丝条穿过雾箱形成丝束，雾化发生器与雾箱通过多个雾口连接，产生的冷却雾进入雾箱与丝条接触，
集油组件包括泵、水管，在雾箱底部收集汇聚后多余的雾化液，废弃或处理后循环使用。
进一步地，所述雾化发生器的雾口与雾箱通过管道连接。
进一步地，所述雾箱上部开有圆形孔，大小与丝条组占据的面积相同，雾箱底部设置有供丝束穿过的孔、与集油组件连接的孔道。
相应地，公开一种无风式纺丝设备，包括纺丝箱体、喷丝板及上述无风式纺丝冷却成形装置。
 有益效果

图中，1、雾化液容器；2、雾化发生器；3、雾箱。
 本发明的最佳实施方式
如图2所示，一种无风式纺丝冷却成形装置，包括：雾化液容器（1）、雾箱（2）、集油组件。水与纺丝油剂在雾化液容器中混合、存放。雾化发生器（2），位于纺丝箱体下方，所述雾化发生器（1）的雾口与雾箱（2）通过管道连接。对上述混合液进行雾化，形成冷却雾。雾箱（2）呈锥筒状，上部和底部开口，熔融、喷丝后的丝条穿过雾箱（2）形成丝束；雾化发生器（1）与雾箱（2）通过多个雾口连接，雾化发生器（1）产生的冷却雾进入雾箱（2）与丝条接触。集油组件，在雾箱（2）底部收集汇聚后的雾化液，对多余的雾化液废弃或处理后循环使用。
所述雾箱（2）上部开有圆形孔，大小与丝条组占据的面积相同，雾箱（2）底部设置有供丝束穿过的孔、与集油组件连接的孔道。
 本发明的实施方式
一种无风式纺丝冷却成形装置的纺丝设备，包括纺丝箱体、喷丝板及上述无风式纺丝冷却成形装置。
本发明重点在于提供一种颠覆性的纺丝冷却成形工艺，如图2、3所示，工序包括雾化、冷却、上油。其工作过程如下：熔融体经过喷丝板形成丝条，膨化后进入雾区冷却；将纺丝油剂与水按照一定比例混合后，混合比例可以为1:9，也可以为其他更合适的比例。产生的水雾进入雾化装置，对丝条进行降温；水雾同时使纺丝油剂附着在丝条上，对丝条进行上油。丝条冷却、成形后形成丝束，进入下道工艺。
冷却雾除了附着在丝条上，多余的冷却雾会汇聚、掉落至雾箱2底部，此时需要对多余的冷却雾回收，不然会造成污染或浪费。为了方便收集，雾区位于半封闭腔体内，收集后的纺丝油剂液体废弃或处理后循环使用。
如图2所示，根据化纤丝条成型特性，雾区冷却分为多段进行，雾化装置通过雾口向雾区输送冷却雾，每段的雾口数量与大小根据成形工艺要求有所区别。丝条经过膨化区后，温度从268℃降至150℃，上部需要产生的雾量更多，在冷却区通过大量冷却雾，降温至120℃，丝条逐步在雾区成形，温度降低至室温（20℃左右）。
为了适应极寒与炎热地区的工作状况，还包括纺丝油剂水溶液的温度调节步骤，在进入雾化装置前，或在雾化装置内，对纺丝油剂水溶液进行温度调节，以免影响雾化效果以及冷却效果。
本发明的工作原理：
如图1所示，现有的化纤纺丝，熔融体由挤压机从纺丝箱、喷丝板挤出冷却成形，成形过程需要适当的冷却，现有的冷却方法是采用大功率制冷设备产生的冷风来进行冷却成形。冷风即使按照实际工况中风速恒速的最高要求，以0.5—0.6m/s的风速与丝条接触，由于丝条在膨化后，由268℃降至150℃，但温度依然较高，柔软的丝条在0.5—0.6m/s的风速也会发生抖动，冷却定型过程影响了丝的品质。
同时，工业空调造价高昂，需要安装各类冷却、送风、除湿、降温、除尘设备，消耗大量铜材、铝材、不锈钢型材。同时传统纺丝冷却成形工艺，为了满足常年保持恒温、恒湿、恒速、高洁净的要求，造价与维护成本高昂。在实际使用过程中，每个纺丝工位需要3.5kw功耗，消耗大量电能。而本发明采用的雾化发生器，每个纺丝工位仅需要300w功耗。
而本发明，去掉制冷设备，雾化发生器将油剂与水的混合液进行大量雾化，不断产生的雾经雾口到达雾箱，高温的化纤丝经雾箱由雾对它进行冷却。本发明所采用的纺丝油剂与水的混合液，以其中一个实施例举例，水与纺丝油剂比值为9:1，而水的热比容远远大于空气，同时形成冷却雾后，与丝条进行充分接触，冷却效率更高。
由于无需风机，冷却雾与丝条在无风状况下接触，避免传统工业空调送风方式对丝条品质的影响。
需要注意的，产生的雾量根据化纤丝的工艺进行设定，由于化纤丝在成形过程中需要分段冷却，本发明通过调整雾口数量和大小进行，达到化纤成形工艺要求。
化纤纺丝过程中除了需要冷却外还需要上油剂，上油剂的目的是防静电、多根抱合与增加平滑性。原有的风冷是冷却完成后单独进行上油工序，现在雾冷雾中就有纺丝工艺要求的油量。无需上油环节。增加了上油的均匀性。
本发明创新性改变工艺后，除了取消上油点，通过雾化接触使上油更均匀。更重要的目的在于节省纺丝冷却环节的成本，这些成本降低包括工业空调转变为雾化发生器的采购与安装调试环节、正常工作时的能耗环节、维护保养环节。
以上显示和描述了本发明的基本原理、主要特征及优点。本行业的技术人员应该了解，上述实施方式只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
 工业实用性
本发明创新性改变工艺后，除了取消上油点，通过雾化接触使上油更均匀。更重要的目的在于节省纺丝冷却环节的成本，这些成本降低包括工业空调转变为雾化发生器的采购与安装调试环节、正常工作时的能耗环节、维护保养环节。
