Abstract

In a plastic injection-moulded, perforated tubular support body (1) for a large-format cartridge-like filter element which safeguards this against internal or external pressure load, one tube end of the support body (1) is provided on its inside with an abutment-like undercut (3) and the other tube end is provided on the outside with an abutment-like undercut (4) which is adapted in shape to the undercut of the other tube end in the manner of a connection means in such a way that two or more support bodies (1) can be joined via their shared push-in connection (3, 4). The abutment-like undercut (4) of one tube end is designed as a surrounding ring and the undercut (3) of the other tube end is designed in segments so that these segments can yield elastically when the undercut elements are pushed into one another. Fused-on locks (5, 6) to prevent twisting and annular sealing elements for axial securing of the support body (1) to the filter element and, if necessary, for radial centring in a housing facilitate the handling of a large filter element. Removal of the modular support bodies (1) and their re-use is thus also provided (Fig. 1). <IMAGE>

Description

Die Erfindung betrifft einen perforierten, rohrförmigen Stützkörper aus Kunststoff für ein patronenförmiges Fil­ terelement. Derartige innere oder äußere Stützkörper sind durch die DE-OS 31 45 552 bekannt. Filterelemente werden in unterschiedlichen Größen und Durchmessern gebaut und die dafür notwendigen Stützkörper müssen diesen verschiedenen Längen angepaßt werden. Sowohl von der Herstellung der Formwerkzeuge als auch von der Vielfalt der Lagerhaltung entstehen sehr hohe Kosten. Zumindest bei Filterelementen mit sehr großem Durchmesser, z.B. bis zu einer Größe von 250 mm und einer Länge von 1000 mm werden die Formwerk­ zeuge für derartige Kunststoffspritzkörper sehr teuer.The invention relates to a perforated, tubular Support body made of plastic for a cartridge-shaped fil terelement. Such inner or outer support bodies are known from DE-OS 31 45 552. Filter elements built in different sizes and diameters and the necessary support body must have this different Lengths can be adjusted. Both from the manufacture of the Forming tools as well as the variety of warehousing there are very high costs. At least with filter elements with a very large diameter, e.g. up to a size of The molding is 250 mm and a length of 1000 mm witness for such plastic injection molding very expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, mit einfachen Mitteln eine Stützkörperform zu schaffen, die sich den Bedürfnissen bezüglich unterschiedlicher Länge und Lagerhaltung anpassen läßt.The invention is therefore based on the object simple means to create a support body shape that the needs of different lengths and Warehousing can be adjusted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Stützkörper an beiden Rohrenden eine widerlagerförmige Hinterschneidung erhält, die so in ihrer Form aufeinander abgestimmt sind, daß zwei damit ausgerüstete Stützkörper über ihre gemeinsame Steckverbindung verbindbar sind und auf diese Weise modulartig unterschiedliche Gesamtlängen eines Stützkörpers erreichbar sind. Ein Widerlager ist dabei zweckmäßig an einem Rohrende als umlaufender Ring ausgebildet und das andere Widerlager am anderen Rohrende ist segmentförmig ausgebildet, so daß diese Segmente beim Ineinanderstecken der Hinterschneidungselemente federnd nachgeben können. Angeformte Verdrehsicherungen und ring­ förmige Abschlußelemente zur axialen Sicherung des Stütz­ körpers am Filterelement und gegebenenfalls zur radialen Zentrierung in einem Gehäuse erleichtern die Handhabung eines Großfilterelementes der eingangs genannten Art. Damit ist auch ein Entfernen der Stützkörper und deren Wieder­ verwendung gegeben.This object is achieved in that the Support body on both pipe ends an abutment-shaped Undercut maintains each other in their shape are coordinated that two support bodies equipped with it are connectable via their common plug connection and in this way, module-like different overall lengths of a support body can be reached. Is an abutment expediently at one end of the tube as a circumferential ring trained and the other abutment at the other end of the pipe is segment-shaped, so that these segments when Interlocking of the undercut elements resilient can give in. Molded anti-twist devices and ring shaped end elements for axially securing the support  body on the filter element and possibly to the radial Centering in a housing facilitate handling a large filter element of the type mentioned is also a removal of the support bodies and their re-installation given use.

Der Erfindungsgedanke ist in einem Ausführungsbeispiel anhand der beiliegenden Zeichnung näher erläutert. Dabei zeigt:The inventive concept is in one embodiment explained in more detail with reference to the accompanying drawing. Here shows:

Fig. 1 einen Längsschnitt durch drei ineinandergesteckte Stützkörper, die sich lediglich durch die Art der Perforation unterscheiden und Fig. 1 shows a longitudinal section through three nested support bodies, which differ only in the type of perforation and

Fig. 2 einen Detailschnitt durch die Randausbildung eines Stützkörpers und der Abschlußelemente. Fig. 2 shows a detail section through the edge formation of a support body and the end elements.

Der rohrförmige Stützkörper 1 weist eine Vielzahl von Per­ forationen 2 in Form von Schlitzen oder Bohrungen auf und hat an einem Ende auf der Innenseite eine Hinterschnei­ dung 3, welche durch Schlitze 3′ derart unterbrochen ist, daß mehrere federnde Kreissegmente am Rand gebildet sind und das andere Rohrende weist außenseitig eine wider­ lagerartige Hinterschneidung 4 auf, die im Ausführungs­ beispiel umlaufend als Ring ausgebildet ist. Durch die damit gebildete gemeinsame Steckverbindung 3, 4 lassen sich gemäß Fig. 1 eine Vielzahl von Einzelstützkörpern 1 in einer gewünschten Länge verbinden.The tubular support body 1 has a plurality of Per forations 2 in the form of slots or holes and has at one end on the inside an undercut 3 , which is interrupted by slots 3 'such that several resilient circular segments are formed on the edge and that the other end of the tube has a bearing-like undercut 4 on the outside, which in the embodiment is designed as a circumferential ring. The joint connector 3 , 4 thus formed allows a large number of individual support bodies 1 of a desired length to be connected according to FIG. 1.

Vorzugsweise weisen die Stützkörper eine Verdrehsicherung 5, 6 auf, die aus mindestens einer Nase 5 in der einen Hinterschneidung 4 und aus mindestens einer entsprechend geformten Ausnehmung 6 in der anderen Hinterschneidung 3 besteht. Zur Verbindung mit einem Gehäuse sind Filter­ elemente am offenen Ende üblicherweise mit einem Verrie­ gelungskonnektor ausgestattet. Durch die Verdrehsicherung 5, 6 wirken die einzelnen Stützkörper 1 insgesamt wie ein Teil.The support bodies preferably have an anti-rotation device 5, 6 , which consists of at least one nose 5 in one undercut 4 and at least one correspondingly shaped recess 6 in the other undercut 3 . For connection to a housing, filter elements are usually equipped with a locking connector at the open end. Due to the anti-rotation device 5 , 6 , the individual support bodies 1 act as one part.

Zur axialen Fixierung eines Filterelementes in mitein­ ander verbundenen Stützkörpern 1 sind gemäß Fig. 2 an beiden Enden zusätzliche Ringscheiben 7 und 8 vorgesehen, die ebenfalls in die Hinterschneidung 3, 4 und Verdreh­ sicherungen 5, 6 eingreifen. Die eine Ringscheibe 7 weist außerdem eine radiale Ausnehmung 10 auf, die mit einer entsprechenden Nase am Verriegelungskonnektor des nicht dargestellten Filterelementes korrespondiert. Alternativ kann die Ringscheibe 7 auch mehrere vorstehende Zapfen 9 aufweisen, die in Zapfenlöcher in einer Endkappe des Filterelementes eingreifen und den Stützkörper 1 verdreh­ sicher mit dem Filterelement lösbar verbinden.For axial fixation of a filter element in mitein other connected support bodies 1 2 additional ring disks 7 and 8 are provided according to FIG. 2, which also engage in the undercut 3 , 4 and twist fuses 5 , 6 . The one annular disc 7 also has a radial recess 10 which corresponds to a corresponding lug on the locking connector of the filter element, not shown. Alternatively, the annular disk 7 can also have a plurality of projecting pins 9 which engage in pin holes in an end cap of the filter element and securely detachably connect the support body 1 to the filter element.

Die obere Ringscheibe 8 hat radial abstehende Vorsprünge 11, mit denen sich relativ hohe Filterelemente im Innenraum eines Gehäuses zentrieren und gegen Verkanten abstützen und sichern lassen.The upper washer 8 has radially protruding projections 11 with which relatively high filter elements can be centered in the interior of a housing and supported and secured against tilting.
