一种挠性流体密封外壳,以一织物构成用以输送及密封大量容积的流体,尤其是淡水,其具有一锥形前及/或后部,一端部固定于其上且以夹制机构的形式密封该外壳。
Description
技术领域
本发明有关于一种挠性流体密封外壳(以下表示为“FFCV”)用以输送及容装大容积的流体,尤其是具有小于盐水的密度的流体,更详言之,为淡水,以及其制造方法。
背景技术
以挠性容器用于货物,尤其是流体或液体货物的密封及输送为已知。使用容器以输送流体于水中,尤其是盐水,为已知。
若货物为流体或流体状固体,其密度小于盐水时,无须使用坚硬笨重平底船、油轮或密封外壳。更确切地说,挠性密封外壳可供使用且被自一位置拖曳或推动于另一位置。此种挠性外壳具有超越坚硬外壳的显著优点。此外,挠性外壳,若适当构成,可容许其于货物已被移除及储存之后可被卷收或折收以供回程用。
遍及全世界,许多地区紧缺而需要淡水。淡水为冰帽及冰山的产物,其迅速浮出为大产业。然而,无论淡水于何处取得,经济节省的输送是关心想要的目的。
例如,目前冰帽收获者想要使用具有150,000吨容量的油轮椅输送淡水。很明显的,此不仅涉及使用此输送工具的成本,而且包含其回程、卸货的额外费用以载运新到货物。当挠性容器外壳为清空时可被折叠及储存于例如拖船上,其将之拉至卸货点,就此而言可降低费用。
即使具有此优点,以节省经济状况要求输送于该挠性容器外壳的容积足以克服输送的费用。据此,即发展愈来愈大的挠性容器。然而,即使已发展好几年,有关于此种容器的技术问题仍存留着。基于此,挠性密封外壳或平底船的改善已教示于美国专利2,997,973;2,998,973;3,001,501;3,056,373;及3,167,103。挠性密封外壳的使用通常为用于输送或储存液体或可流动固体,其具有一比重小于盐水者。
盐水的密度相较于该液体或可流动固体的密度,反应一事实,即当一部分或完全充满袋被放置及拖曳于盐水中时货物提供浮力供该挠性输送袋用。此货物浮力提供该容器的浮动且有助于该货物自一海港装运于另一海港。
在美国专利2,997,973中,公开一种外壳,包括一挠性材质的封闭管,例如渗有天然或合成橡胶编织体,其具有一流线型突出头可适以连接于拖曳装置,及一或多管体与该外壳内部连通,以供装填及清空该外壳。通过该外壳的液体容量供应浮力,且其形状依据其被装填程度而定。此专利同时明示该挠性输送袋可以单一织物编织制成一管体。然而,其并未教示如何达到如此巨大的管体。显然,此构造将需处理缝线的问题。由于袋体一般以补片工作方式来制成,利用缝针或其他方式将防水材的补片连接一起,因此于商业用挠性输送袋通常可发现缝线。例如见美国专利3,779,196。然而,当该袋体被重覆受到高负载时缝线是袋体破裂的原因。很明显的袋体破裂可于一无缝线构造避免之。然而,由于一缝线构造一单一编织织物的替代品且具有不同的优点,尤其于制造上,因此若可产生一缝线管体且不会有缝线处破裂的倾向的袋体,是最令人满意的。
基于此,美国专利5,360,656名称为“压制毛毡及制造方法(PressFelt and Method of Manufacture)”,1994年11月1日发证且共同转让,其公开在此可供参考,公开一压制毛毡的基本织物是以螺旋缠绕织物条所制造而成。
该织物的长度将通过该纱线材质的织物条的各螺旋转折的长度所决定,且其宽度将通过这些螺旋转折数目所决定。
一缘部接合可通过例如不织布材质或具熔化纤维的不织布材质的缝纫、熔化及熔接来达成(举例来说,超音波熔接,如美国专利5,713,399名称为“抄纸机衣物用的邻接条的超音波缝线(Ultrasonic Seaming ofAbutting Strips for Paper Machine Clothing)”,于1998年2月3日发证且共同转让,其公开在此可供参考)。
尽管此专利是有关于产生压制毛毡用的一基本织物,此种技术可应用于产生一充分坚固管状结构以供一输送容器用。此外,以一输送容器的预期使用,而不是想要一压制织物,其中于织物条之间具滑顺转变,此不是需要特别注意的事且可作不同接合方法(重叠及缝纫、黏接、钉接等)。其他型式的接合对本领域普通技术人员是为已知。
此外,尽管如前所述,一无缝线挠性容器为优选且已于现有技术提到,用以制造此结构的方法及装置有其困难处。迄今,如所注意的,大量挠性容器一般是以小段部一起缝制或接合所制成。这些段部必须为不透水。一般而言此段部,若非以不透水材质制成,可于安装之前易于设置有一覆膜。此覆膜可通过现有方式例如喷雾或浸泡覆膜实施。
另一总是是如何密封该容器的端部,尤其是呈锥形端部处是需要密封的。端部可分开制成且附接于该管状构造,如前述应用及于此引述参考所提的例子。其亦可宜使这些端部形成于该管状结构本身之外,且成形惟一适意形状(即圆锥形等)。基于此,例如,Hawthorne的美国专利2,997,973发证于1961年8月29日,显示织物于端部处打褶的使用,其再胶黏及/或缝纫以形成该适意形状。
据此,对用于输送大容积流体的FFCV存在有一需求,即克服伴随于此结构及其操作环境的上述问题。
发明内容
因此,本发明的主要目的在于提供一种相当大织物FFCV,用以输送货物,货物尤其包含淡水,其具有以一适意方式密封其端部的装置。
本发明的进一步目的在于提供一种用以密封与其端部的锥形相关联的FFCV端部的装置。
本发明的进一步目的在于提供一种用以密封此FFCV端部的装置,以有效分布其上的负载。
这些及其他目的和优点将由本发明来实现。基于此,本发明使用一编织螺旋形成或片段管体以产生该FFCV,具有300呎或更多的长度与40呎或更多的直径。如此大的结构可于制造纸制衣物的机器上制造。该管体的端部,有时候称为鼻头部及尾部,或船头部及船尾部,可通过数装置密封。端部可固定于该管体,以螺旋形成或其他形式形成于该管体本身之外。本发明是针对这些端部的特定构形。然而,于所形成管体具有一大概为130至245呎或更多的大型一致环周时,需要将该环周降低至一可控制尺寸,以容许一端盖或拖曳构件固定其上。尽管如此做,宜适意使该端部管体呈锥状以呈例如一圆锥部或一船的船头部,而维持一体构造。
一旦该FFCV的管体的端部降低成一可控制环周时,一端封闭机构再固定其上。基于此,该端封闭机构包括二连锁部,各具有配合圆锥或弯弧表面,以供夹制该织物于其间。除了密封该FFCV的端部,该机构亦可包含界面特征,例如流体流动口用以装载及卸下与一用以装载及卸下的耦接机构一起的货物。一拖曳勾套亦可成为该机构的一部位。
附图说明
因此通过本发明,其目的及优点将可实现,其详细说明需配合参可图式,其中:
图1为一种习用FFCV的概略示意图,其呈圆柱形且具有一尖头侧或突出头;
图2为一FFCV的概略示意图,其呈圆柱形且具有一平坦头侧或突出头;
图3为结合本发明的教示的端部封闭机构的侧剖视图;及
图4为结合本发明的教示,具有图3所示的机构的一FFCV的部分透视图。
具体实施方式
该FFCV10概指为以一不透水纺织管体所构成者。尽管该管体或管状结构12构成配置可变化,所示该管体(于图1中)一般为呈圆柱形,其具有实质上一致直径(周边)且再封闭及密封于各端14及16上。这些各别端14及16可以任何数量的方式封闭。如将讨论的本发明将使用一特定方式。所产生的不透水结构亦必须具足够挠性以被收折或卷收以供搬运及储藏。
于设计该FFCV以抵抗置于其上的负载时,需考虑特定因素。基于此,于2001年4月11日申请的相关申请(co-pending)美国专利申请号09/832,739,名称为“挠性流体密封外壳”,详细提出此等因素,除了有关于该FFCV所要的其他特征外,以及供该织物用的可能材质,其构造及可能施予其上的覆膜及方法以提供该织物不透水性。据此,在此其进一步说明将不再重复,而可参考该申请案。
并且,本装置可应用于有关螺旋成形FFCV,如公开于2001年7月18日申请的相关申请美国专利申请号09/908,877,名称为“螺旋成形挠性流体密封外壳”中。
除此之外,可参考2001年8月3日申请的美国专利申请号09/921,617,名称为“挠性流体密封外壳的端部及其制造方法”,其是有关于该FFCV的端部可能的构造,本发明是针对在此所公开的特定构形。并且,2001年8月7日申请的美国专利申请号09/923,936,名称为“挠性流体密封外壳的覆膜及其制造方法”公开除了可能覆膜外,以及该织物的其他构造。
尽管前述申请案说明该FFCV设计中不同重要影响,本申请案是针对用于封闭一FFCV的头部及/或尾部的特定装置。本发明显示一锥形结构以通过打褶或其他装置降低其环周成可控制的尺寸,如美国专利申请号09/921,617所公开者。
该FFCV10包含一管体12及端部,概标示为14为头部及16为尾部(未示于图4)。所示构造容许将一管体12转变为一圆锥形头部14及/或一圆锥形尾部16。打褶、收折或美国专利申请号09/921,617所公开的其他方式可容许将该管体12的端部转变为较小直径。例如,这些打褶部18可形成绕于该管体12环周,以容许该管体12的端部形成锥形或具有较小环周,如图4所示。
以此点,我们现在转向该端封闭机构30的构造,其可用以封闭该FFCV的一或两端。该机构30包括二连锁部。具有一前或向外部32及一后或向内部34。制成该FFCV10的管状结构的织物20于头端处(及/或尾端处)被打褶,概如图4中打褶部18所示。该部34于该FFCV10内且形状为圆形。此包含一连续密封环36,其安装于一辐支撑构件38上。该构件38包括数轮辐或轮叶40将环36耦接于一轴向轮毂42。轮叶40可容许流体于装填及清空该FFCV期间通过该部34。该部34宜以不会与货物互相作用的材质制成,根据其组成,其可为一高强度金属(即不锈钢)或强化合成物,且构成为一单件式。
环36于其端处包含一圆锥或弯弧部44。此弯弧部44可将该织物20夹制于该部32上。基于此,该部32包含一圆形环纳置部46。该部46包含一环形弯弧或斜表面48,用以紧密配合该环36的衔接弯弧部44。一夹制螺丝纳置构件50设置于该部32的中心内。基于此,一夹制螺丝52设置以穿过该轮毂42及构件50的轴向开口53。于该织物20被定位于该部44与该表面48之间后,螺丝52的螺纹部54接受一向下螺接的螺帽56。
于该FFCV的管状部被适意打褶且这些打褶部被密封或接合于适当位置以将该端降低至适当环周之后,该夹制机构30再被放置于其上。该部44及表面48产生相符合圆锥表面以供该织物被夹制于其间。锁紧该螺丝52产生一密封于该织物两侧之间,其可抵抗一实质上压力差且防止流体流出(例如,自该FFCV的内侧58至外侧60)。若需要,密封剂说可使用于此区域,以确保产生密封。相较于单一平板片,该圆锥形状以相等轴向负载可于该织物内产生较高的压缩负载,且当受到负载时具有自我中心倾向。
该环36的弯弧部44凸伸于该织物的较高压力侧(内部58)内,以致于增加流体压力可引起增加密封力于该织物与表面48之间。这些弯弧部偏离且给予一和缓转变几何形状,其可产生该织物内较低应力集中及改善该织物的耐用性。
应注意的是,该机构30的非夹制区中使用缓和半径范围,亦可降低对负载范围及移动状况的局部化紧密几何变化。
所需夹制力是通过应用一负载支承构件或夹制螺丝52的简单线性负载所产生。亦可使用其他型式的装置,例如具有空气或水力释放的弹簧夹或一过心(over-center)锁紧装置或其他适用于其目的的装置。
应注意的是,由于该部32亦将与货物接触,其亦与任何其他与货物接触的构件或表面,必须以不与货物产生作用的材质制成,根据其组成物,可如前述者,为高强度金属(即不锈钢)或强化合成材质。该部32具有数流体流动口62。这些流体流动口62可通过轮叶(未图示)所界定,其将该构件50连接于该环纳置部46。除此之外,该部32包含一管状延伸部64,其内部于这些流体流动口62形成流体连通。此延伸部64可配置以设置有一装填或清空装置以供密封及握持。一加盖装置66是固定以密封该延伸部64,其可被打开以供装填或清空货物。一拖曳勾套68可固定于该盖66上或于该夹制机构30上的其他位置,用以固定一拖曳缆线。当然,此仅是用以举例说明目的,且其适意构形及位置是本领域普通技术人员所知。
前述夹制机构具有明显倾向的优点。这些包含通过锁紧该负载支承构件以增加该织物上压力的能力,以于需要时增加该夹制力。并且,通过提供该夹制的表面之间的相对和缓几何形状改变,以降低该织物上应力集中。现有密封及耦合设备于需要时亦可容易连结。除此之外,这些夹制表面可变化以供不同应用。例如,其可非常浅以供该织物的平坦表面,及较尖锐以供较高压缩负载或于该织物的弹性为一因素之处。并且,该夹制机构的配置可使其上的拖曳力可能用以增加所产生的夹制力,如本领域普通技术人员所知。
尽管在此已公开及详细说明优选实施例,其并未藉此限制范围;如此其范围需以申请专利范围决定。
