Abstract

The unit has a zig-zag-shaped folded filtering medium, which is provided with sealed side strips along folded slots, where the unit is formed as a circular filter unit. End folds stand opposite to each other and are connected with each other. The sealed side strips overlap or stand in partial contact with each other. The filtering medium is provided with a fleece material at two front sides, which run transverse to the end folds. The fleece material is adhered at the filtering medium.

Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Filterelement bestehend aus einem zick-zack-förmig gefalteten Filtermedium.The The invention relates to a filter element consisting of a zig-zag folded filter medium.

Stand der TechnikState of the art

Aus dem Stand der Technik sind Rundfilterelement aus einem zick-zack-förmig gefalteten Filterpapier oder Filtervlies bekannt. Diese Rundfilterelemente sind an ihren Stirnseiten mit Endscheiben versehen. Ein Rundfilterelement wird zunächst aus einer Filtermaterialbahn hergestellt und zwar durch zick-zack-förmiges Falten der Materialbahn. Diese wird in eine konzentrische Form gebracht und Endscheiben an die Stirnseiten dieses Filtermediums angeklebt oder angeschweißt. Bei dem Verfahren muss darauf geachtet werden, dass der Faltenabstand gleichmäßig ist und jede Falte von der benachbarten Falte einen gewissen Abstand aufweist damit eine gleichmäßige Filterbeladung erfolgen kann.Out The prior art circular filter element from a zigzag-shaped folded filter paper or filter fleece known. These round filter elements are at their End faces provided with end plates. A round filter element is first made of a filter material web by zig-zag folding the material web. This is brought into a concentric shape and end plates adhered to the end faces of this filter medium or welded. In the process, care must be taken that the pleat spacing is uniform and each fold from the adjacent fold a certain distance thus has a uniform filter loading can be done.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde ein Filterelement zu schaffen, das mit hoher Präzision hergestellt werden kann und bei dem mit geringem Aufwand ein einheitlicher Faltenabstand erzielbar ist. Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst. Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.Of the Invention has for its object to provide a filter element, that made with high precision can be and with a little effort a uniform pleat spacing is achievable. This object is achieved by the features of the independent claim 1 solved. The invention will be explained in more detail with reference to embodiments.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

Es zeigt 1: Ein Filterelement mit SeitenstreifenIt shows 1 : A filter element with side strips

2: Das in 1 dargestellte Filterelement in konzentrischer Form 2 : This in 1 illustrated filter element in concentric form

3: Eine Variante des in 1 gezeigten Filterelements, welches ebenfalls in eine konzentrische Form gebracht wurde. 3 : A variant of in 1 shown filter element, which has also been brought into a concentric shape.

Ausführungsform(en) der ErfindungEmbodiment (s) the invention

Das in 1 dargestellte Filterelement besteht aus einem Filtermedium, welches zick-zack-förmig gefaltet ist und an den beiden quer zu den Falten verlaufenden Stirnseiten mit einem Vliesmaterial versehen ist. Dieses Vliesmaterial ist beispielsweise an dem Filtermedium angeklebt. Durch diese Anordnung werden Filtertaschen gebildet. Die Filtermaterialbahn wird in einem nächsten Prozessschritt zu einem konzentrischen Filterelement geformt (2). Dabei überlappen sich die überstehenden Seitenstreifen an der oberen Stirnseite und an der hier nicht dargestellten unteren Stirnseite. Diese Seitenstreifen können miteinander verklebt werden. Gleichzeitig werden die beiden sich gegenüberstehenden Endfalten ebenfalls mit einander verbunden, so dass ein zuverlässig abgedichtetes Rundfilterelement entsteht.This in 1 filter element shown consists of a filter medium, which is folded zig-zag and is provided at the two transverse to the folds end faces with a nonwoven material. This nonwoven material is, for example, adhered to the filter medium. By this arrangement, filter bags are formed. The filter material web is formed in a next process step to a concentric filter element ( 2 ). In this case, the overlapping side strips overlap on the upper end side and on the lower end side, not shown here. These side strips can be glued together. At the same time the two opposing end folds are also connected to each other, so that a reliably sealed round filter element is formed.

3 zeigt ebenfalls die Bildung eines Rundfilterelements. Hier stehen jedoch die Seitenstreifen nicht über. Dadurch entsteht ein geringfügiger keilförmiger Abstand zwischen den Seitenstreifen. Sofern die beiden Seitenstreifen am inneren Öffnungsdurchmesser zumindest partiell verbunden sind, ist dieser Abstand jedoch unerheblich. Selbstverständlich kann durch eine Verbindungstechnik auch ohne überstehende Seitenstreifen eine zuverlässige Abdichtung des Rundfilterelements geschaffen werden. Sofern eine Verklebung der Seitenstreifen auf deren gesamten Höhe erfolgt, entsteht keine Keilöffnung. 3 also shows the formation of a round filter element. Here, however, the side stripes are not over. This creates a slight wedge-shaped distance between the side strips. If the two side strips are at least partially connected at the inner opening diameter, but this distance is irrelevant. Of course, a reliable sealing of the round filter element can be created by a connection technique without protruding side strips. If a gluing of the side strips takes place on their entire height, no wedge opening is created.
