Description

一种聚酯纤维用纺丝组件及其组装装置和方法 技术领域
本发明属于纺丝组件技术领域，涉及一种聚酯纤维用纺丝组件及其组装装置和方法。
背景技术
纺丝组件作为聚酯纤维纺丝中的核心部件，其作用是将计量泵计量过的聚合物熔体精细过滤掉机械杂质和凝聚粒子、充分混合以及匀化熔体，并在一定压力下通过喷丝板微孔，挤出形成初生纤维，一般地，可根据不同规格的聚酯纤维选择不同的压力挤出成纤维。
近年来随着化纤工业在制造能力、技术设备、品种开发及产品质量方面的不断进步，“新合纤”正朝着大容量、超细和差别化功能纤维的方向发展。在细化常规产品的同时，注重大容量、功能性纤维设备及成套工程技术的开发，努力降低消耗和减少污染，提高产品质量和可靠性。增大纺丝容量可进一步降低单位产能投资和生产成本，有力提高产品的市场竞争力，而要增大聚酯纤维纺丝容量关键是设计出大容量的纺丝组件，在这种需求下DIO纺丝组件便应运而生。
DIO纺丝组件即一套组件内设有两个过滤熔体的滤室，通过一块喷丝板两个区域的喷丝头挤出成形，作为纺丝工艺流程中的心脏，在纺丝过程中起着举足轻重的作用。纺丝过程中对纺丝组件的过滤效果、受热均匀性和密封性要求非常高，这些特性决定了纺丝设备对聚合熔体进行均匀过滤的连续性和纤维的质量。DIO纺丝组件不仅过滤效果要好，而且两个区域内的各个组合件之间必须要密封好，如果有一组合件出现松动，在纺丝过滤熔体时，会出现两个滤室内熔体过滤效果不同，同一锭组件内压力差别比较大，导致纤维截面粗细不均，严重时还会引起漏浆或飘丝、成品丝毛丝等异常，严重影响产品质量。在现有技术的DIO纺丝组件装置中，砂杯外底部和喷丝板之间采用密封圈密封，来提高密封的可靠性，但砂杯外底部与喷丝板之间接触的面没有设置过滤网和凸台，密封圈在外力挤压下，容易变形错位，起不到密封作用，两腔室内熔体相互串浆，且熔体过滤效果不好；砂杯内腔室底部设置圆孔作为熔体通道，没有设置缓冲熔体的导流孔，对熔体的分流效果不良；组件上盖与紧固环之间没有设置弹簧挡圈，各组合件之间容易松动，影响熔体过滤效果；在DIO纺丝组件的组装过程中，作为将DIO纺丝组件的全部组合件紧固在本体内的紧固环起到重要的作用，现有的组装技术方案是将圆形卡环放入紧固环内，通过手柄操作将紧固环紧固在组件上口内，此方法在手动操作中容易出现组件内各组合件之间受力不均，而导致松动，影响熔体过滤效果，出现纤维截面异常等，不能保证正常生产，且效率低，耗材损耗大，而且组装质量也得不到保证。
发明内容
