Ringfilterelement mit die Stirnseiten dicht abdeckendem platten- oder folienförmigem DichtmaterialRing filter element with plate or foil-shaped sealing material tightly covering the front sides

Die Erfindung betrifft ein Ringfilterelement mit einem die Stirnseiten dicht abdeckendem platten- oder folienförmigem Dichtmaterial nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a ring filter element with a plate- or film-shaped sealing material that tightly covers the front sides according to the preamble of patent claim 1.

Zur Schaffung voneinander getrennter Rein- und Rohseiten müssen solche Ringfilterelemente an mindestens einer ihrer Stirnseiten radial innen oder außen in einem Filtergehäuse dicht einsetzbar sein.In order to create separate clean and dirty sides, such ring filter elements must be able to be inserted into a filter housing in a sealed manner on at least one of their front sides, radially inside or outside.

Hier insbesondere gegenüber einer aus FR-OS 2 268 551 bekannten Ausführung eine einfachere und damit insbesondere kostengünstigere Lösung zu finden, ist das Problem, mit dem sich die Erfindung beschäftigt.The problem addressed by the invention is to find a simpler and therefore more cost-effective solution, particularly compared to an embodiment known from FR-OS 2 268 551.

Eine Lösung dieses Problemes wird durch die Ausgestaltung des gattungsgemäßen Ringfilterelementes nach den kennzeichnenden Merkmalen des Patentanspruchs erreicht.A solution to this problem is achieved by designing the generic ring filter element according to the characterizing features of the patent claim.

Zweckmäßige Ausgestaltungen sind Gegenstand der Unteransprüche .Appropriate embodiments are the subject of the dependent claims.

Ausführungsbeispiele der Erfindung, anhand der der Aufbau, die Wirkung sowie die besonderen Vorteile der erfindungsgemäßen Lösung nachstehend noch näher beschrieben werden, sind in der Zeichnung dargestellt.Embodiments of the invention, based on which the structure, the effect and the particular advantages of the inventive solution are described in more detail below, are shown in the drawing.

materialmaterial

Ein Ringfilterelement, bei dem das Filtermaterial 1 ein zick-zack-förmig gefaltetes Filterbahnmaterial aus Filterpapier ist, ist an seinen Stirnseiten mit je einer Endscheibe aus Pappe als Dichtmaterial 2 dicht abgedeckt.A ring filter element, in which the filter material 1 is a zigzag-shaped folded filter web material made of filter paper, is tightly covered on each of its front sides with an end disk made of cardboard as a sealing material 2.

Auf dem Dichtmaterial 2 aus Pappe ist radial innen eine Ringscheibe 5 aus Vlies dicht aufgebracht, die radial innen in die von dem Filterbahnmaterial 1 gebildete Ringöffnung ringförmig hineinragt.An annular disk 5 made of fleece is tightly applied radially on the inside of the cardboard sealing material 2, which extends radially on the inside into the ring opening formed by the filter web material 1.

Die Dichtung des Ringfilterelementes gegenüber einem in die Ringöffnung eingreifenden Gehäusestutzen 3 wird dadurch erreicht, daß sich die radial überstehende Ringscheibe 5 beim Einführen des Gehäusestutzens verformt und sich in diesem verformten Zustand dicht an den Gehäusestutzen 3 anlegt, wobei sie sich gleichzeitig dichtend an dem Innenumfang des Filterbahnmaterials 1 abstützt.The seal of the ring filter element against a housing socket 3 engaging in the ring opening is achieved in that the radially protruding annular disk 5 deforms when the housing socket is inserted and in this deformed state lies tightly against the housing socket 3, while at the same time it rests sealingly on the inner circumference of the filter web material 1.

Um eine definiertere Abstützung der verformten Ringscheibe 5 am Innenumfang des Ringfilterelementes zu erreichen, ist es möglich, zusätzlich einen Abstütz-In order to achieve a more defined support of the deformed ring disk 5 on the inner circumference of the ring filter element, it is possible to additionally provide a support

Die Verbindung der Ringscheibe 5 aus Vlies mit dem von der Papp-Endscheibe gebildeten Dichtmaterial 2 erfolgt durch Ultraschall oder Kleben.The connection of the fleece ring disc 5 with the sealing material 2 formed by the cardboard end disc is made by ultrasound or gluing.

Die Anbringung des Abstützringes 4 erfolgt besonders zweckmäßig dadurch, daß dieser Ring bei der Erzeugung einer Schmelzverbindung zwischen Dichtmaterial 2 und Ringscheibe 5 mit angeschmolzen wird.The attachment of the support ring 4 is particularly expedient in that this ring is melted when creating a fusion connection between the sealing material 2 and the ring disk 5.

Während bei dem beschriebenen Ausführungsbeispiel die mit dem stirnseitigen Dichtmaterial 3 verbundene. Ringscheibe 5 aus verformbarem Vlies nach radial innen über das Filterbahnmaterial 1 hinausragt, kann ein solches radiales Hinausragen der Ringscheibe 5 auch radial außen erfolgen. In diesem Fall ist dann auch der Abstützring 4 dort vorgesehen.While in the described embodiment the ring disk 5 made of deformable fleece connected to the front sealing material 3 protrudes radially inward over the filter web material 1, such a radial protrusion of the ring disk 5 can also occur radially outward. In this case the support ring 4 is also provided there.

Möglich ist es selbstverständlich auch, daß die jeweils mit dem Dichtmaterial 2 verbundene Ringscheibe 5 aus elastisch verformbarem Vlies stirnkantenseitig radial innen und außen das Filterbahnmaterial 1 über-It is of course also possible that the ring disk 5 made of elastically deformable fleece connected to the sealing material 2 extends radially inside and outside over the filter web material 1 on the front edge side.

In Bezug auf eine gute und umweltfreundliche Entsorgung des beschriebenen Ringfilterelementes empfiehlt es sich, das Filter - und Dichtmaterial - gleich oder zumindest gleichartig auszuwählen.With regard to a good and environmentally friendly disposal of the ring filter element described, it is recommended that the filter and sealing material be selected to be the same or at least of a similar type.
