Description
发明领域
本发明涉及分离筛,其主要用途是对混合物的多种成分进行分离,例如对在油田钻探过程中所产生的泥浆或浆料中的固体进行分离或过滤。
发明背景
总体上讲,分离筛被安装在振动器篮中,其中每个振动器篮具有多个筛。因此必须在相邻的筛对接处并且还在筛对接振动器篮处提供密封件。人们已知将一个密封件共同模制(co-mould)到一个筛体的边缘上,并且还用粘合剂或者通过使用紧固件(如螺钉)将一个密封件附接到筛体上。存在着与这些已知技术相关联的多种缺陷,而本发明旨在提供一种不同方式来在筛体上提供密封件。
发明概述
根据本发明,在此提供了一种分离筛,该分离筛具有一个矩形筛体,该筛体的一侧携带着一个密封件用于在一个邻近的筛或篮的一个对接侧面上进行密封,该密封件包括一种弹性材料的狭长的密封条,该狭长密封条被附接到该筛体上的一个止动条在该筛体的所述一侧上保持在位。
该止动条优选地将该密封件夹紧以将其保持在位。
优选的是,该止动条实质上在该密封条的整个长度上延伸,从而使得该密封条的全部长度被牢固地保持在该筛体的所述一侧上,其中该密封条的一部分被夹在该止动条与该筛体的所述一侧之间,并且该密封条的另一部分呈现一个暴露的表面用于在一个邻近的筛的对接侧或者一个振动器篮的对接表面上进行密封。
该止动条与该密封条相接合的区域可以具有如多个尖头的凸出部的构造,这些凸出部弹性地接合该密封条以便改善其保持力。
该筛体可以携带多个伸出部分,这些伸出部分延伸穿过该止动条中的多个开口,以便在制造过程中根据该筛体来将该止动条定位。在该止动条的区域上可以将这些伸出部分的外部末端熔化,以便用作熔化柱,有时也称为热熔柱。这些伸出部分可替代地可以通过一个卡扣作用而与这些开口接合,当这些伸出部分穿过这些开口时它们发生弹性变形,并且随后回弹以将该止动条牢固地保持在该密封条上。这种形式的机械连接避免了对于加热工具的需要。
该止动条可以是与该筛体分别形成的,并且借助于这些伸出部分和开口而附接到其上。可替代地,该止动条可以被预先附接到该筛体上或(如在该优选的实施方案中)可以与该筛体整体地形成。在这种情况下,该止动条优选地通过一个整体模制的铰接件附接到该筛体上,该铰接件允许该止动条相对于该筛体转动(通过一种折叠运动),以便将该止动条带入到其工作位置,在此位置该铰接件将该密封条保持在该筛体上。该铰接件优选地是沿着该筛体的一个下部边缘形成,随后该密封条的暴露的表面沿着该筛体的一个上部边缘延伸。
附图简要说明
现在通过参照附图并通过举例将对本发明进行说明,在附图中:
图1示出了在将一个密封条附接到该筛体上之前根据本发明的一个筛的一侧;
图2示出了在该密封条附接到该筛体上之后图1的筛;
图3示出了两个对接的筛,根据图2的每个筛被装配在一个振动器篮中;
图4是图3的一个放大的视图;并且
图5示出了一种改进的筛体。
附图详细说明
图1示出了一个细分筛的一个矩形筛体1,在使用中该筛体被装配到一个振动器上,以便在钻探油或气时对从井下带来的液体钻探泥浆中的固体进行分离。细分筛总体上包括带有多个肋材的一个框架,该框架上放置了对液体钻探泥中的固体进行过滤的金属丝布。筛体1具有多个槽缝2,跨过这些槽缝延伸有执行分离或过滤功能的金属丝布(未展示)。筛体的一侧3具有一系列的整体模制的圆柱形指销4形式的伸出部分。一个止动条5通过与筛体1进行整体模制而被预先附接到筛体1上,并且通过沿着筛体1的侧面3的下部边缘延伸的一个铰接件6而结合到该筛体上。止动条5具有图1所示的阶梯形的截面形状。当条5处于如在图1所展示的模制成的位置时,条5实质上水平地从该筛体的侧面3延伸并且在其上表面上携带一系列尖头的凸出部7形式的构造,这些尖头的凸出部在两行中延伸几乎到条5的全部长度。
止动条5还具有一系列的开口或孔8,这些开口或孔被定位为使得当条5围绕该铰接件转动时(即如箭头A所示朝向该筛体侧面向上折叠),这些指销4与这些孔8对齐并且能够穿透后者。
止动条5的目的是抓住一个有弹性的或弹性体密封条9(图2)并将其保持在筛体1的侧面3上。密封条9具有恒定的截面形状(一个反转的“L”,如图2所示)并且具有一个与它有待被装配到其上的筛体侧面3的长度相对应的长度。密封条9是由止动条5来保持的,这是通过将止动条5朝向穿过这些孔8的这些指销4折叠,同时捕获密封条9的一个边缘以便将其夹在筛体1与止动条5之间,并且然后由一种加热工具将这些指销4的头部熔化从而使得这些指销4形成塑料铆钉并用作热熔柱。当止动条5被顶在密封条9上时,这些尖头的凸出部7使弹性条9的表面局部变形,由此将该弹性条牢固地锚定在位,使密封条9的另一个边缘的两个表面呈现一个暴露的密封表面用于在一个邻近筛的对接侧面或一个振动器篮的对接表面上进行密封。
止动条5的长度对应于密封条9的长度,并且使用多个间隔开的热熔柱(由这些指销4形成)确保了密封条9沿其全部的长度被牢固地夹紧。
条9可以由橡胶类、天然橡胶、闭孔构造泡沫类、聚氯丁二烯、聚丙烯、热塑性弹性体类(TPE)如聚氨酯类、共聚多酯类、苯乙烯、共聚物类、烯烃类、弹性体合金类、聚酰胺类、硅酮类、腈的化合物类,或者它们的组合,或腈(NBR)化合物类制成。条5和条9的材料必须要耐受油基的泥和水基的泥,因为主要应用是用于从油田钻探的浆料中过滤出固体的过滤筛。
图3和图4示出了如何在一个振动器篮10中定位两个筛体1a和1b,这两个筛体各自沿着一侧装配有一个密封条9。与携带密封条9的侧面相对并且平行的筛体侧面具有一个伸出的凸缘12,这样使得当这两个筛体1a和1b对接时,一个筛的凸缘12接合并压缩了对接筛的密封条,由此在这些筛之间提供一种有效的密封,这种密封防止了进行滤过的物质绕过跨越在这些筛的主要区域上的金属丝。振动器篮10还具有一个伸出的凸缘13,该凸缘接合并密封在邻近的筛1b的密封条9上。
图5的修改是在筛体1上使用了多个卡扣销15来替代指销。这些卡扣销15被劈开并且尺寸被确定为当止动条5被折叠在密封条9上时卡入这些孔8之中。这种附接方法是非永久性的(即这些销钉可以被压缩并且该密封件可以进行替换),但不要求使用用于热铆接的加热工具。
该密封条可以由一种可商购的挤压物来制成,其特性(值得注意的是的弹性)可以通过比共模制(其中可供使用的材料的范围更有限并且在此需要昂贵的工具)更简单并更有效的一种方法来进行评估和最后确定。
使用一种狭长的止动条使夹紧压力沿该密封条的全部长度分散和分布,与使用螺钉相对比,后者将局部化的夹紧压力施加到离散的区域上。此外,将这些指销与该筛体一起模制避免了对于存在的水基或油基的泥可与金属螺钉或粘合剂发生一种可能的不良反应。
