Description
技术领域
本发明涉及一种如权利要求1前序部分所述的、用于内燃机的尤其两级过滤装置、尤其两级空气过滤器,用于从要净化的气体流中分离液体和/或固体的颗粒。
背景技术
由文献DE 10 2008 011 186 A1已知如权利要求1前序部分所述的过滤装置。此外由文献DE 298 19 335 U1已知一个这样的用于内燃机的空气过滤器。在已知的过滤部件中主过滤部件以间隙容纳在过滤器外壳里面。
发明内容
本发明的目的是,这样改进上述形式的过滤部件,使所述主过滤部件无运动地设置在过滤器外壳里面并且尤其防止在顶置装配时所述过滤部件从过滤装置中掉下来。
这个目的通过具有在权利要求1中给出的特征的过滤装置实现。本发明的有利扩展结构和适宜的改进方案在从属权利要求中给出。
本发明的基础在于,所述主过滤部件或初级部件具有至少一个固定部件,它稳定主过滤部件在过滤器外壳里面的位置。这个固定部件从主过滤部件的圆周侧开始在过滤器外壳的方向上延伸并且设计成,使主过滤部件与过滤器外壳以确定的距离设置。因此固定部件防止,所述主过滤部件在过滤器外壳里面运动。
所述主过滤部件最好具有四个分别在其圆周侧上设置的固定部件,其中每两个固定部件基本相互对置或者相互倾斜对置。
除了使主过滤部件在过滤器外壳里面稳定以外,所述固定部件也可以用于,防止主过滤部件从过滤器外壳、例如在打开过滤器外壳时不期望地掉下来。为此,所述过滤器外壳具有至少一个从过滤器外壳圆周侧在主过滤部件方向上延伸的隆起,它支承固定部件并且防止主过滤部件从过滤器外壳中自动掉下来。
为了以简单的方式使主过滤部件安装过滤器外壳里面或者从过滤器外壳里面取出来,所述固定部件最好由弹性材料、例如聚亚胺酯构成。因此固定部件例如以略微增加的力花费越过过滤器外壳的隆起运动。
在一个实施例中,所述过滤器外壳在入流侧配有前部件,其中该前部件设计成旋流预分离器、保护格栅、抽吸弯管或管式空气导管。
在一个有利的实施例中,所述旋流预分离器具有多个小的单个旋流器。这种多室旋流器或者多重旋流器为了预净化气体流具有许多导向叶片,它们使气体流置于旋转,例如在文献DE 10 2008 011 186 A1中描述了这种旋流器。在此,由文献DE 103 30 296 A1已知的旋流分离器可以设计成两级预分离器。
作为主过滤部件或初级部件,它容纳在过滤器外壳里面,例如考虑紧凑空气过滤器,具有许多在入口侧和出口侧的端部平面部位中交替封闭的过滤器通道,它们通过相互衔接地布置光滑层和波纹层形成,在其中气体流直线地通过过滤器通道导引。可以选择使用单层或多层折子式过滤器,具有环形封闭的、锯齿形折叠的过滤折子,最好一个双层折子式空气过滤器,具有围绕较小环过滤部件设置的较大环过滤部件,或者一个锯齿形折叠的、平面过滤部件。
所述过滤介质最好是基本上管形或椭圆形的。例如可以如同在文献DE 10 2008 011 186 A1中描述的那样,其中多层匣式过滤器中每个过滤器匣设计成星形过滤器,具有星形设置的、粘附在入流侧和/或排流侧的过滤折叠。特别有利地使过滤折叠端面棱边粘附在入流侧上和/或排流侧上,例如利用所谓的端面棱边粘胶。
附图说明
如上所述,存在不同可能性,以有利的方式实现并改进本发明的理论。为此一方面参阅后置于权利要求1的权利要求,另一方面在下面借助于附图1至8所示的实施例详细解释本发明的其它扩展结构、特征和优点。附图中:

相同或类似的扩展结构、部件或特征在图1至8中配有一致的附图标记。
具体实施方式
在图1中示出的过滤装置或两级分离器100是内燃机的空气过滤器。这个空气过滤器由过滤器外壳30(在其中容纳主过滤部件20、所谓的初级部件)、旋流预分离器10以及后置的次级部件50组成。通过空气过滤器100导引的气体流在第一过滤器级的旋流预分离器10和第二过滤器级的主过滤部件20里面净化。次级部件50防止,在更换主过滤部件20时污物进入到内燃机里面。
所述滤器外壳30在其圆周侧面上具有开孔36,它由通过封闭部件62可拆卸地设置和封闭的盖60遮盖。通过这个在过滤器外壳30的外壳面中的开孔,可以径向或垂直于过滤装置100的轴向将主过滤部件20并且适宜地也将次级部件50安装在过滤器外壳30内部的容纳室里面,或者从其中取出来。过滤器外壳30具有未净化侧入口32和净化侧出口34,用于要净化的气体流。
旋流前过滤器10设置在过滤器外壳30的入口32部位。在旋流预分离器10里面来自轴向流入空气的脏污颗粒通过离心力在旋转的空气流里面向外携带并且分离。通过可以向下指向的颗粒出口12可以去除在旋流预分离器10中已经分离的脏污颗粒。旋流预分离器10由独立的部件构成,它与过滤器外壳30连接。在旋流预分离器10里面预过滤的流体轴向输送到主过滤部件的端面入流侧。旋流预分离器10、主过滤部件20和次级部件50可以轴向位于前后并且尤其没有偏转地在轴向通流要净化的燃烧空气。例如,如果使用具有在主通流方向上设置的、交替封闭的通道的紧凑空气过滤部件的时候,可以实现无偏转的通流。
图2示出图1的过滤装置100,其中拆下盖60和主过滤部件20。主过滤部件20在其面对过滤器外壳30未净化侧入口32的一侧上具有用于在两个相互嵌接的、环形的、锯齿形折叠的主过滤部件20的过滤折子之间建立气体密封连接的、入流端的密封部件40。这个入流端的密封部件40最好由弹性材料、例如聚亚胺酯构成并且在其圆周侧上具有固定部件、即聚亚胺酯榫舌或间隔榫22,它们使安装到过滤器外壳30里面的主过滤部件20以与过滤器外壳30确定的距离固定(参见图3和4,其中图4示出在图3中利用虚线框出的部位)。此外聚亚胺酯榫舌22在打开过滤器外壳30盖60时作为用于主过滤部件20的榫舌-防掉落保护。如图5至7所示(图7示出在图5中利用虚线框出的部位),聚亚胺酯榫舌22在打开盖60时与过滤器外壳30的隆起38共同作用并且使主过滤部件20保持在过滤器外壳30里面。因为侧面的聚亚胺酯榫舌22放置在过滤器外壳30的隆起38上,它们防止主过滤部件20自动掉下来。由于聚亚胺酯榫舌22的弹性能够使主过滤部件20以略微增加的力花费从过滤器外壳30里面拉出来。在此聚亚胺酯榫舌22一起顶压并且在隆起38上滑动。
在图3和4中聚亚胺酯榫舌22与过滤器外壳30的隆起38间隔地设置。图3和4示出装配在过滤器外壳里面的主过滤部件。在打开盖60时主过滤部件20在孔36方向上滑移,并且间隔榫舌22使主过滤部件20保持在过滤器外壳30里面(参见图5至8)。
图8示出在拆下次级部件20时过滤装置100的侧视图。流出端的密封部件42这样顶靠在过滤器外壳30的净化侧出口34的密封座70上,使未净化侧与净化侧分开。通过两个设置在入流端的密封部件40上的聚亚胺酯榫舌22(它们悬挂在过滤器外壳30的隆起38上)和顶靠在密封座70上的流出侧的密封部件42防止主过滤部件20从过滤器外壳30掉下来。聚亚胺酯榫舌22设计成使主过滤部件20稳定在过滤器外壳30里面,它也附加地作为防掉落保护并且可靠地防止主过滤部件20不期望地从过滤器外壳30掉下来。
