Abstract

Ring filter, with sealed covering plates or film at the end sides, has a mouldable sealing material (2), and extends radially inwards and/or outwartds, in a ring, at least at the end side of the filter material (1). Filter (1) and/or sealing material (2) are of a fusible material, to be welded together. Sealing material (2) is pref. a fusible non-woven. Filter material (1) has a support ring (4) at the end sides, without projection and inserted axially, for the sealing (2) to project radially in a ring from it. As the filter (1) and sealing (2) are welded together, the support ring (4) is welded into place at the same time. Ring disc, of mouldable material, can be placed over the sealing at least at one end side of the filter, projecting radially inwards and/or outwards, using a fusible material to be welded to the sealing, pref. of a fusible non-woven. Filter has an axially inserted support ring, at the end sides, which is welded into place with the filter and seal.

Description

Die Erfindung betrifft ein Ringfilterelement mit ei­ nem die Stirnseiten dicht abdeckenden platten- oder folienförmigen Dichtmaterial nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a ring filter element with egg nem the face or plate or film-shaped sealing material according to the preamble of Claim 1.

Zur Schaffung voneinander getrennter Rein- und Roh­ seiten müssen solche Ringfilterelemente an mindestens einer ihrer Stirnseiten radial innen oder außen in einem Filtergehäuse dicht einsetzbar sein. Zu diesem Zweck waren bisher besondere Dichtringe in diesen Be­ reichen zwischen dem Filterelement und dem Gehäuse notwendig.To create separate pure and raw such ring filter elements must at least one of its end faces radially inside or outside in a filter housing can be used tightly. To this The purpose was previously special sealing rings in these Be range between the filter element and the housing necessary.

Hier eine einfachere und damit insbesondere kosten­ günstigere Lösung zu finden, ist das Problem, mit dem sich die Erfindung beschäftigt.Here a simpler and therefore cost in particular Finding a cheaper solution is the problem with the invention is concerned.

Eine Lösung dieses Problemes wird durch eine Ausge­ staltung des gattungsgemäßen Ringfilterelementes nach den kennzeichnenden Merkmalen des Patentanspruchs 1 erreicht.A solution to this problem is provided by a design of the generic ring filter element after the characterizing features of claim 1 reached.

Zweckmäßige Ausgestaltungen sind Gegenstand der Un­ teransprüche.Appropriate configurations are the subject of the Un claims.

Ausführungsbeispiele der Erfindung, anhand der der Aufbau, die Wirkung sowie die besonderen Vorteile der erfindungsgemäßen Lösung nachstehend noch näher be­ schrieben werden, sind in der Zeichnung dargestellt.Embodiments of the invention, based on the  Structure, the effect and the special advantages of solution according to the invention below in more detail are written are shown in the drawing.

Es zeigenShow it

Fig. 1 einen Längsschnitt durch ein Ring­ filterelement mit radial innen über­ stehendem Stirnkanten-Dichtmaterial, Fig. 1 shows a longitudinal section through a ring filter element provided with radially inwardly protruding end edge-sealing material,

Fig. 2 eine alternative Ausführung des Ring­ filterelementes in der Darstellungs­ weise nach Fig. 1 mit einer ringför­ migen Abstützung für das radial stirnkantenseitig über stehende Dicht­ material. Fig. 2 shows an alternative embodiment of the ring filter element in the representation, as shown in FIG. 1 with a ring-shaped support for the radial end edge over standing sealing material.

Ein Ringfilterelement, bei dem das Filtermaterial ein zick-zack-förmig gefaltetes Filterbahnmaterial aus Filterpapier ist, ist an seinen Stirnseiten mit einem schmelzbaren Vlies als Dichtmaterial 2, das selbst ebenfalls ein Filtermaterial ist, dicht abge­ deckt.A ring filter element, in which the filter material is a zigzag-folded filter web material made of filter paper, is tightly covered on its end faces with a fusible fleece as sealing material 2 , which is itself also a filter material.

Die dichte Abdeckung kommt dadurch zustande, daß das Vlies 2 durch Ultraschall- oder induktives Schweißen auf das Filterbahnmaterial 1 aufgeschmolzen ist.The tight cover comes about because the fleece 2 is melted onto the filter web material 1 by ultrasound or inductive welding.

Das aus Vlies bestehende Dichtmaterial 2 ragt radial innen in die von dem Filterbahnmaterial 1 gebildete Ringöffnung ringförmig hinein.The sealing material 2 made of nonwoven material projects radially 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 das radial überste­ hende Dichtmaterial beim Einführen des Gehäusestut­ zens verformt und sich in diesem verformten Zustand dicht an den Gehäusestutzen 3 anlegt, wobei es sich gleichzeitig dichtend an dem Innenumfang des Filter­ bahnmaterials 1 abstützt.The seal of the ring filter element with respect to an engaging in the ring opening housing connector 3 is achieved in that the radially overstepping sealing material deforms when inserting the housing connector and in this deformed state fits tightly against the housing connector 3 , while at the same time sealing against the inner circumference the filter sheet material 1 supports.

Um eine definiertere Abstützung des verformten Dicht­ materials 2 am Innenumfang des Ringfilterelementes zu erreichen, ist es möglich, zusätzlich einen Abstütz­ ring 4 im Inneren des Ringfilterelementes in demjeni­ gen Bereich vorzusehen, in dem das Dichtmaterial 2 von dem in das Ringfilterelement einzuführenden Ge­ häusestutzen 3 verformt wird.In order to achieve a more defined support of the deformed sealing material 2 on the inner circumference of the ring filter element, it is possible to additionally provide a support ring 4 in the interior of the ring filter element in the region in which the sealing material 2 is deformed by the housing connector 3 which is inserted into the ring filter element Ge becomes.

Die Anbringung des Abstützringes 4 erfolgt besonders zweckmäßig dadurch, daß dieser Ring bei der Erzeugung der Schmelzverbindung zwischen Dichtmaterial 2 und Filterbahnmaterial 1 mit an das Filterbahnmaterial oder das Dichtmaterial 2 angeschmolzen wird. Ist al­ lein das Dichtmaterial 2 aus einem schmelzbaren Mate­ rial, wird der Stützring 4 vorteilhafterweise mit diesem Dichtmaterial schmelzverbunden.The attachment of the support ring 4 takes place particularly expediently in that this ring is also melted onto the filter web material or the sealing material 2 when producing the fusion connection between the sealing material 2 and the filter web material 1 . Is alone the sealing material 2 made of a fusible mate rial, the support ring 4 is advantageously melt-bonded to this sealing material.

Während bei dem beschriebenen Ausführungsbeispiel das stirnseitige Dichtmaterial nach radial innen über das Filterbahnmaterial 1 hinausragt, kann ein solches ra­ diales Hinausragen auch radial außen erfolgen. In diesem Fall ist dann auch der Abstützring 4 dort vor­ zusehen.While in the described embodiment the sealing material on the end protrudes radially inward beyond the filter web material 1 , such a radial projection can also take place radially on the outside. In this case, the support ring 4 can also be seen there.

Möglich ist es selbstverständlich auch, daß das Dichtmaterial 2 stirnkantenseitig radial innen und außen das Filterbahnmaterial 1 überragt, um innen und außen in ein Filtergehäuse dicht eingesetzt zu wer­ den.It is possible, of course, that the sealing material 2 inside and outside projects beyond the front edge side radially, the filter sheet material 1 to the inside and outside tightly inserted into a filter housing at the polls.

In bezug auf eine gute und umweltfreundliche Entsorg­ barkeit des beschriebenen Ringfilterelementes emp­ fiehlt es sich, das Filter - und Dichtmaterial - gleich oder zumindest gleichartig auszuwählen.With regard to good and environmentally friendly disposal Availability of the described ring filter element emp if the filter - and sealing material - select the same or at least similar.
