Description

计量装置及氨纶干法纺丝部件 技术领域
本发明涉及纤维生产领域，具体涉及一种计量装置及氨纶干法纺丝部件。
背景技术
在氨纶干法纺丝生产工艺中，化学原料经过聚合反应形成聚合物溶液，聚合物溶液经过管道输送至每个纺丝工位，在每个纺丝工位聚合物溶液被计量装置精确计量和分配；从计量装置出口出来的较小溶液流进入纺丝组件内被过滤、保温并经喷丝头喷出后进入一个含有高温的空腔纺丝箱，溶液流在纺丝箱经工艺处理形成丝束，将丝束收卷就形成了氨纶。
如图11所示，现有氨纶干法纺丝部件包括计量装置和纺丝组件1d，计量装置包括一计量泵头1a，计量泵头1a是泵头生产厂家的标准产品，通常包括一个进口和多个出口1b，计量泵头的出口1b(多个)在一个或多个圆周上非线性分散排列，纺丝组件的进口1e(多个)在两条具有一定间隔的直线线性分散排列，计量泵头的出口1b的非线性排列方式和纺丝组件的进口的线性排列方式是不对应的，为了实现二者连接通常需要采用金属软管1c，简洁起见，图中仅示意了部分计量泵头的出口1b经部分金属软管1c与部分纺丝组件的进口1e连接的情形。
随着氨纶纺丝工艺技术的不断发展，每个纺丝工位生产的氨纶根数不断增多，并且氨纶更细，采用上述计量装置时，计量装置的出口和纺丝组件的入口连接需要采用很多的金属软管，这样就增加了很多连接头，由此增加形成漏点的可能性；此外，不同金属软管的长度、弯曲程度等很难保证完全相同，由此可能造成计量后的溶液流到达纺丝组件内的喷丝头前的压力不同，因此经过喷丝头喷出的溶液的流变性可能不同，特别是对于更细的溶液流差别更大，进而造成从同一个纺丝箱出来的氨纶的物理性能可能不一致。

本发明的发明人在实践本发明实施例的过程中发现，如果计量装置的出口与纺丝组件的进口无需采用金属软管而可直接对应连接，则可克服现有技术中因采用金属软管连接可能导致的缺陷，但如何在计量装置的出口与纺丝组件的进口之间无需采用金属软管而实现直接对应连接，亟待提出高效的解决方案。
为此，请参考图1，本发明实施例提供了一种计量装置，包括：
至少一计量单元1和至少一第一转换板2；
一所述计量单元1包括至少一进口；
一所述计量单元1的至少一侧面设有呈非线性排列的多个出口，与一所述第一转换板2的至少一侧面设有的呈对应非线性排列的多个进口对应连通；
一所述第一转换板2的下端面设有呈线性排列的多个出口，一所述第一转换板的一进口与一出口之间通过一导流转换通道连通。
在如氨纶等纤维干法纺丝生产中，如氨纶等纤维干法纺丝用的聚合物溶液经所述计量单元的进口流入以进行精确计量和分配，所述计量单元计量好的多股小溶液流分配至各所述第一转换板的进口、经各相应的所述导流转换通道后自所述第一转换板的出口流出。经所述第一转换板的出口流出的溶液流进入如氨纶等纤维干法纺丝的后道工序中的纺丝组件，以进行过滤、保温和/或喷丝等处理，喷出的丝束在含有高温的空腔纺丝箱中进行溶剂挥发，形成如氨纶等纤维丝束。
本发明实施例中：所述“非线性排列”包括多个进口或出口作为一组或分为多组，各组进口或出口的排列方式分别采用非直线的方式进行排列，例如，每组进口或出口分布在某圆周或某圆弧上，等等；所述“呈对应的非线性排列”包括不同组进口或出口的非线性排列方式相同或相似，例如，不同组进口或出口分散排列在相同半径的圆周或圆弧上且一一对应连通，或者，不同组进口或出口分散排列在半径不同的圆周或圆弧上且一一对应连通；所述“线性排列”包括多个进口或出口作为一组或分为多组，各组进口或出口的排列方式采用直线的方式进行排列，例如，每组进口或出口分别分散排列在某直线或分散排列在多条具有一定间隔的平行直线上，等等；所述“呈对应的线性排列”包括不同组进口或出口的线性排列方式相同或相似。所述“圆周”、“圆弧”、“直线”用于表示多个进口或出口中心连线或轮廓线的大致轨迹形状。
本发明实施例中：以计量单元中心轴线(图中虚线所示)延长线为参考线，所述计量单元的沿该参考线左右方位的表面为该计量单元的左右侧面，位于左方位的表面为该计量单元的左侧面，位于右方位的表面为该计量单元的右侧 面；一所述计量单元的左侧面、右侧面中的至少一个侧面连接有一第一转换板，第一转换板与计量单元连接的某表面为该第一转换板的一个侧面，根据相对左右方位的不同相应表示为该第一转换板的左侧面或右侧面；一所述第一转换板的左侧面、右侧面中的至少一个侧面连接有一计量单元；所述第一转换板上下两个表面分别称为上端面和下端面。所述第一转换板的进口、导流转换通道、出口，可根据实际工艺的需要设计为相互连通的不同部位，或者，也可设计为某一整体部件的不同部位，如进口和出口分别为导流转换通道的两端等等，本发明实施例对此不做限制。
本发明实施例提供的技术方案通过在计量装置中增设所述第一转换板，一方面计量单元至少一侧面呈非线性排列的多个出口与设于其侧面的第一转换板呈非线性排列的多个进口匹配直连，另一方面所述第一转换板呈非线性排列的多个进口经多个导流转换通对应连通设于其下端面的呈线性排列的多个出口，由于第一转换板下端面设有的多个出口呈线性排列，因此，该方案实现了将计量单元的出口的非线性排列方式转换为线性排列方式。所述计量装置可应用但不限于氨纶等纤维干法纺丝生产中，以实现计量装置的出口与纤维纺丝部件等后道工序中如纺丝组件等设备线性排列的多个进口的匹配直连。
例如，在氨纶干法纺丝生产中，计量装置用于对氨纶制备用聚合物溶液进行精确计量和分配，并将计量和分配后的小溶液流分别输送到纺丝组件以进行氨纶生成的后道工序处理。目前，纺丝组件的多个进口主要采用线性排列，本发明实施例提供的计量装置中第一转换板的出口的线性排列方式可根据纺丝组件的多个进口的线性排列方式对应设计，这样，采用本发明实施例提供的计量装置就可将现有计量单元的非线性排列方式转换为线性排列方式的出口，使之与纺丝组件的多个进口的线性排列方式匹配(如线性排列方式相同且位置对应)，由此实现了计量装置的出口与纺丝组件的进口之间无需金属软管即可实现直接对应连接，节省因布置金属软管接头需占用的空间，节省的空间可以布置更多的溶液流进出口，使得纺丝组件可以在有限的空间内喷出更多的丝束，从而提高效率，降低产品的生产成本。
本发明实施例提供的技术方案中，可选的，所述计量单元和所述第一转换板可拆卸式连接，以提高清洗、维护、装配等的方便性。

可选的，参考图1和图2，至少一所述第一转换板2还设有至少一溶液进口25，一所述溶液进口25经一溶液导流通道与一所述计量单元1的至少一进口连通，这样，经第一转换板的溶液进口就可以为计量单元提供如氨纶干法纺丝用聚合物等溶液的总进口，提高了第一转换板的集成度，使得的计量装置的整体结构更为紧凑，提高空间利用率。所述溶液进口的开设位置可根据实际需要确定，可选的，所述溶液进口25可设于第一转换板2的上端面，以提高布局的灵活性。在包括多个所述第一转换板的情形下，可根据实际需要，在每个所述第一转换板上设所述溶液进口和所述溶液导流通道，也可选择在其中部分所述第一转换板上设所述溶液进口和所述溶液导流通道，实现方式非常灵活，本发明实施例对此并不限制。

其中，所述纺丝组件包括多个进口，多个进口呈线性排列，例如，根据氨纶干法纺丝生产的实际需要，可将纺丝组件的多个进口分散排列在一条直线上，或者，可将纺丝组件的多个进口分散排列在多条具有一定间隔的平行直线上。
所述计量装置可将氨纶干法纺丝用聚合物溶液进行精确计量和分配，将计量单元多个出口的非线性排列方式转换为与所述纺丝组件多个进口的线性排列方式对应的线性排列方式，并可与所述纺丝组件的进口匹配直连。
一种可选的实现方式中，一所述第一转换板的至少部分出口与所述纺丝组件的至少部分进口呈对应的线性排列且对应连通，氨纶干法纺丝用聚合物溶液至少经一所述计量单元的进口和一所述第一转换板的出口进入所述纺丝组件。该方案中，氨纶干法纺丝用聚合物溶液至少经一所述计量单元的进口和一所述第一转换板的出口进入纺丝组件内，被过滤、保温并经喷丝头喷出后进入一个含有高温的空腔纺丝箱，溶液流在纺丝箱经工艺处理形成丝束，将丝束收卷就形成了氨纶。其中，所述第一转换板和所述纺丝组件的数量和装配方式，可根据实际工艺生产需求确定，实现方式非常灵活。
例如，可一个第一转换板对应一个纺丝组件。第一转换板下端面呈线性排列的多个出口与该纺丝组件呈对应线性排列的多个进口匹配直连，由此节省了计量装置与纺丝组件连接所需的金属软管，提高了空间利用率和产能。
又例如，可多个第一转换板公用一个纺丝组件，如图9所示，一计量装置包括六个第一转换板2，各第一转换板下端面呈线性排列的出口分别与一所述纺丝组件6的部分进口呈对应的线性排列且对应连通。该方案可通过多个第一转换板将多个计量单元的出口，转换为满足如氨纶等纤维干法纺丝后道工序中如纺丝组件等设备呈不同线性排列的多个进口匹配直连的出口排列方式，以实现灵活布局，更好满足纤维工艺生产差异化的实际需求。
再例如，可多个纺丝组件公用一个第一转换板，如一所述第一转换板的部 分出口与一纺丝组件呈线性排列的进口匹配直连、其他部分出口与另一纺丝组件呈线性排列的进口匹配直连，该方案可将一个第一转换板的多个出口匹配直连到多个纺丝组件各自呈线性排列的进口，以实现灵活布局，更好满足纤维工艺生产差异化的实际需求。
另一种可选的实现方式中，一所述第二转换板的至少部分出口与所述纺丝组件的至少部分进口呈对应的线性排列且对应连通，氨纶干法纺丝用聚合物溶液至少经一所述计量单元的进口和一所述第二转换板的出口进入所述纺丝组件。该方案中，氨纶干法纺丝用聚合物溶液至少经一所述计量单元的进口和一所述第二转换板的出口进入纺丝组件内，被过滤、保温并经喷丝头喷出后进入一个含有高温的空腔纺丝箱，溶液流在纺丝箱经工艺处理形成丝束，将丝束收卷就形成了氨纶。其中，所述第二转换板和所述纺丝组件的数量和装配方式，可根据实际工艺生产需求确定，实现方式非常灵活。
例如，可一个第二转换板对应一个纺丝组件。如图10所示，位于第二转换板5下端面呈线性排列的多个通孔的出口与该纺丝组件6呈对应线性排列的多个进口匹配直连，由此节省了计量装置与纺丝组件连接所需的金属软管，提高了空间利用率和产能。
又例如，可多个第二转换板公用一个纺丝组件，位于各第二转换板下端面呈线性排列的多个通孔的出口分别与一所述纺丝组件的部分进口呈对应的线性排列且对应连通。该方案可通过多个第二转换板将计量单元的出口，转换为满足如氨纶等纤维干法纺丝后道工序中如纺丝组件等设备呈不同线性排列的多个进口匹配直连的出口排列方式，以实现灵活布局，更好满足纤维工艺生产差异化的实际需求。
再例如，可多个纺丝组件公用一个第二转换板，如位于一所述第二转换板的下端面的部分通孔的出口与一纺丝组件呈线性排列的进口匹配直连、其他部分通孔的出口与另一纺丝组件呈线性排列的进口匹配直连，该方案可将一个第二转换板的多个通孔的出口匹配直连到多个纺丝组件各自呈线性排列的进口，以实现灵活布局，更好满足纤维工艺生产差异化的实际需求。
可见，本发明实施例提供的氨纶干法纺丝部件实现了计量装置的出口与纺丝组件的进口之间无需金属软管即可实现直接对应连接，节省因布置金属软管接头需占用的空间，节省的空间可以布置更多的溶液流进出口，使得纺丝组件可以在有限的空间内喷出更多的丝束，从而提高效率，降低产品的生产成本。
可选的，所述纺丝组件与至少一所述计量装置可拆卸式连接，以进一步提 高设备清洗、维护等的方便性和效率。
