Description

中空纤维约束系统
技术领域
本发明涉及一种用于薄膜过滤系统中的中空纤维的约束系统。
背景技术
过去使用了通常以焊接塑料网笼形式的许多不同类型的约束系统，但是这些系统当在网中需要大孔以允许流体流过时都缺乏刚度并且在输送、安装或使用期间网的任意部分在破损的情况下难以修补。虽然这些已知的约束系统便宜且制造简单，但是它们在许多所要求的设备中不坚固耐用。
本发明目的在于克服或至少改善现有技术的一个或多个缺点或者至少为公众提供一种有用的可选方案。
发明概述
根据一个方面，本发明提供一种用于中空纤维的约束系统，它包括多个彼此间隔开并且由多个分散的间隔元件支撑的纵向延伸元件，每个间隔元件大体上与所述纵向元件垂直地延伸，从而与所述纵向元件结合形成笼状结构。
优选的是，该笼状结构为管状。优选的是，纵向元件是杆，并且间隔元件是环的形式。可以理解的是，这些环可以为任意几何形状，并且不限于圆形。同样，管状结构和杆可以是任意几何横断面形状。
在一个优选形式中，每个环具有许多用于可拆卸地啮合相应的杆的径向延伸的啮合结构。这些结构可以采用部分圆形的相对凸缘的形式，这些凸缘间隔成提供与相应杆过盈配合或搭扣配合的插座。
在另一个优选形式中，每个环具有许多在其圆周上间隔开的径向延伸的切口，每个切口其尺寸和形状设定成与相应的杆形成过盈配合或搭扣配合。优选的是，每个环的内表面沿着每个内部边缘是倾斜的。更优选的是，每个环的内表面设有缓冲元件。优选的是，该缓冲元件是由泡沫材料形成的并且在两个端部处延伸穿过每个环的长度，从而重叠在每个环的内部边缘上。
这些间隔元件可以由许多在使用中紧固在一起的子元件形成。
这些切口或插座优选在环的圆周上等距离隔开。
优选的是，这些杆在它们与相应的间隔件啮合的位置处直径或宽度是减小的。优选的是，通过圆周凹槽或狭缝来提供所述减小的直径。
该系统的部件优选由大体上刚性的塑料材料通常为尼龙和丙烯腈-丁二烯-苯乙烯(ABS)形成。这些部件可以模制或机加工成所要求的结构。这些切口优选其横断面为部分圆形，并且具有稍微小于直径的开口以用于杆的搭扣配合固定。
附图的简要说明
现在参照附图只是以实施例的方式对本发明的优选实施方案进行说明，其中：
图1显示出根据本发明的一个实施方案的约束系统的透视图；
图2显示出图1的约束系统的间隔部件的透视图；
图3显示出图1的约束系统的放大的分解透视图；
图4显示出根据本发明的第二实施方案的约束系统的透视图；
图5显示出图4的约束系统的扣环的透视图；
图6显示出图4的约束系统的配接环部件的透视图；
图7显示出根据第三实施方案的约束系统的透视图；
图8显示出图7的约束系统的配接环部件的透视图；

图10显示出根据第四实施方案的约束系统的透视图；
图11显示出图10的约束系统的配接环部件的透视图；
图12显示出图10的约束系统的配接环部件的透视图；并且
图13显示出图4的约束系统的端部的放大的透视图。
优选实施方案的详细说明
参照图1-3，该约束系统包括大体上为管状的笼形结构5，它由多根彼此间隔开并且通过多个纵向间隔开并且横向延伸的间隔环7保持不动的纵向延伸的杆6形成。
在该实施方案中的每个间隔环7具有许多在其圆周上等距离间隔开的啮合插座8。每个插座8由部分圆形的相对凸缘9形成，这些凸缘间隔成提供与相应的杆6进行过盈配合或搭扣配合。这些插座8在形状上稍微超过半圆形以提供杆6的固定。
参照附图中的图4-13，在这些实施方案中的每个环7具有许多在其圆周上等距离间隔开的径向延伸切口10，每个切口10其尺寸和形状设定成与相应的杆6形成过盈或搭扣配合。在该实施方案中的切口10在形状上稍微超过半圆形以提供杆6的固定。
在该实施方案中的杆6设有圆周凹槽或狭缝11以在它们与环7啮合的位置处提供减小的直径/宽度。这用来防止这些环相对于杆6进行纵向运动。
管状约束结构5的每个端部设有终止配接环12，该配接环在使用中将该结构5安装在密封套筒16等上。该配接环12包括具有多个开口14以使得流体能够从中通过的内环13以及径向延伸的圆周肋条15。肋条15还设有与设在间隔环7上用来与杆6的端部17啮合的那些切口一样的相应数量的切口16。
如在这些实施方案中所示一样，间隔环7优选以紧密间隔开的成对方式布置。另外，杆和环的数量可以根据约束要求来改变。如在图10中可以最清楚地看出，杆数目的密度也可以沿着管状结构5的长度变化，其中约束要求沿着长度是变化的。
该约束系统用来约束在过滤系统中所采用的一束中空纤维薄膜。该纤维束在管状约束系统内纵向延伸。该约束系统使得流体能够从中空纤维薄膜中流进和流出。通常，这些纤维在上下头部之间延伸，这些头部与约束系统一起用来形成一种可更换的纤维束模块。在这些布置中，笼子其附加的优点在于，在利用该模块期间保护纤维束。
要理解的是，在不脱离本发明的精神和范围的情况下可以对本发明作出其它实施方案和范例。
