Description
技术领域
本发明涉及一种过滤器滤筒,特别地但非限制性地涉及一种适用于过滤油或燃料的过滤器滤筒。
背景技术
众所周知,过滤器采用一外部过滤器本体来安装用后即可丢弃的过滤器滤筒,外部本体通常有一圆筒状外壳和一顶盖,一同轴的回流管通常有螺纹端,顶盖旋到螺纹端上夹住在外壳内处于运行状态的滤筒。流体流过进口,流过滤筒内的过滤器媒质并通过回流管流出。失效的滤筒只要简单地用一新的替换就可以了。我们知道典型的滤筒由装在塑料或金属圆筒内的纸卷筒组成。WO/0037232描述了一个例子。使用了不同的可替换的结构和流动形态。
欧洲专利申请P0556506A1描述了一模块过滤系统,该系统由装在塑料壳内紧紧卷绕的纸过滤器媒质制成的滤筒组成。塑料壳在它的顶部和底部表面具有一体地形成的网格状结构以允许流体流入和流出过滤器。选定壳体的尺寸,使它紧紧围绕纸媒质。过滤器滤筒可在外壳内叠起堆放,外壳可在其中容纳大量滤筒来提高过滤器的能力。每个壳体由相同的上下两半组成,其中圆柱形壁绕着纸卷筒夹在一起。当使用两个滤筒时,一个滤筒的网格状顶部邻接另一个的网格状底部,以便流体连续地从一个滤筒流到下一个滤筒。这样流体仅从一端单向流动,在另一端出来回收。在这种情况下,中心管是输入管而不是回流管。
我们也知道其它的结构,其中流体在相反的方向同时流入过滤器,并在中心回收,参见例子澳大利亚专利729523和美国专利4792397。
澳大利亚专利729523和WO/0037232描述了一种装有纸卷筒过滤器媒质的喷射模制过滤器滤筒。与欧洲专利申请P0556506A1的滤筒不同,该滤筒端部都是开放的,没有使用网格状端部。这样可以使用压力机在压力下插入纸卷筒。在一个滤筒内,滤筒的相对端完全敞开,所以该滤筒成为一带有回流通道的管,该管具有两个背靠背并被线网隔开的纸卷筒。纸卷筒有纸板制成的中心孔作为回流管。这样当滤筒被夹住在过滤器壳内时,流体从滤筒两端的壳入口流入,经过纸卷筒,并流出纸卷筒的端部,经过线网形成的公共回收通道被回收到中心回流管。线网分隔卷筒的相对端,为过滤流体提供流体通道。线网也用在澳大利亚专利659793的布置中,以分隔一个金属筒内的两个纸卷筒。
在美国专利4792397中,除了用特别制造的卷筒之间的流体收集器替换用于分隔卷筒的线网外,在美国专利4792397中使用的背靠背纸卷筒与澳大利亚专利729523和WO/0037232的设置类似。流体收集器具有从基本上是平面的部分的两侧凸起的接近并间隔开的同心隆起,压力平衡孔穿过平面部分。隆起在连接器的相对侧挤入纸卷筒。每个隆起之间的间隙允许径向回收流到中心回流管。
在澳大利亚专利650176中,一金属筒设有带端壁凹槽以提高径向回流。在澳大利亚专利申请59243/00中,流体收集器设置在外壳的端壁内,流体连接器有由径向流动通道分隔的圆的扇形区域。
采用所有这些例子的流行设计标准是横过端部支持纸以保持回流并使因为纸破裂造成可能阻止流动的阻塞最小化。因为当过滤器媒质老化并变得填满时,过滤器被挤压可能会使得回流区域变形并导致阻塞。这样在上述例子中,通常在纸卷筒的端部用带有相对大的流体通道、优选为金属丝线网的流体收集器来提供充足量的支承。
本发明在维持更大的穿过过滤器的回流效率的同时,采用一完全不同的解决支持卷筒问题的方法。
发明内容
本发明一方面提供了过滤器滤筒,它具有:一中空外部本体,所述中空外部本体每端都有开口;一对带有一进口端和一出口端的过滤元件,它们以纵向隔开的关系安装在外部本体中,且出口端附近设有一回流通道;形成回流通道的隔片装置,特征在于,隔片装置有相对的纵向间隔开的筛支架,相应的筛支撑在所述间隔开的筛支架上,,所述隔片装置设置在相应过滤元件之间,而筛设置在过滤元件和筛支架件之间,以供滤液通过筛流进回流通道。
优选地,隔片装置包括由周向间隔开的径向延伸叶片保持间隔开的径向隔开的内和外环件,叶片将两环件连接在一起,叶片纵向延伸并具有在叶片间形成开放的扇形区域的相对边缘,叶片边缘是所述筛支架,并在叶片之间提供回流通道,内环有与回流通道相通的流体穿过通道。
优选地,隔片装置包括叶片组周向错开的两个分开隔片。
优选地,隔片装置呈轮状,有由周向间隔开的径向轮辐结构连接的一中心毂和一外轮缘,中心毂有流体穿过通道结构,使滤液能够从与径向轮辐结构相邻的区域流到毂中的中心通道。
优选地,隔片装置包括滑进中空本体并中心地设置在中空本体内壁中的周向延伸并纵向隔开的反跟踪隆起之间的两个相同的隔片。
优选地,过滤元件是纸卷筒,中空本体包括从它的内壁突出并与过滤元件紧密接触的间隔开的隆起。
附图说明
为了更容易地理解本发明及其实际效果,现在参照附图进行说明,附图显示了本发明的优选实施例,其中:
图1是根据本发明的过滤元件的纵向剖视图,该过滤元件在横截面上是圆柱形的;
图2和3分别是标准隔片的剖视图和平面图,图1的实施例中使用了两个这种隔片;
图4和5分别是适于与图2和3的隔片一起用的网眼筛的侧视图和平面图;
图6是显示图4和5的网眼筛的结构的部分剖视图。
具体实施方式
参照附图,首先图1显示了一过滤器滤筒10,在该例中包括一喷射模制的圆筒状塑料本体11,该本体11具有间隔的反跟踪隆起12,隆起沿着中空本体11的内表面13不均匀地设置。作为过滤元件的第一和第二纸卷筒14和15在压力下被推进中空本体11,被中心地设置在中空本体11中的隔片16装置分隔开。每个纸卷筒14和15都包括一位于中心的圆筒形中心部分16,以便当滤筒夹住在外壳(未示出)内时,回流管(未示出)可以插过滤筒。流体沿箭头方向流过过滤器,向回和径向穿过隔片装置16,穿过孔17,这样滤液流到回流管(未示出)。
在图示的实施例中,隔片装置16由两个分开的隔片18组成,隔片通常制成图2和3所示的辐条轮的形式。由于隆起12,一个单一的同样大小的隔片因刚性太强而不能插入,所以用两个隔片。
参照图2和3,隔片18包括一外环19和一内环20,内环20在上部有四个孔或凹穴21,在它的对侧偏移45度同样设置四个等间隔的孔21,故总共八个孔,这些孔提供了穿过内环20的流体穿过通道21,塑料连接部分22在环19和20之间径向延伸。
因为外部本体11由较硬的塑料材料制成,且隔片18也是由较硬的塑料材料制成,因此选择隔片18的尺寸,以便隔片18可被推过隆起12进入位置。
网格筛22在纸过滤元件14和15插入之前设置在隔片18顶上。
图4、5和6显示了优选的网格筛,网格筛包括锥形筛元件23。在这个实施例中,网格筛优选地是喷射模制,并形成有与中心孔24相邻的边缘部分25和外圆周边缘部分26形成,其中形成外圆周边缘部分26以防止可能导致网格筛部分进入滤液的任何磨损碎屑。
上述作为本发明说明的例子给出,同时,对本领域普通技术人员来说,很明显可以在不脱离所附权利要求的广泛的界限和范围内做各种变形和变化。
