Abstract
Description
Die Erfindung betrifft einen rohrförmigen Stützkörper für einen ringförmigen Filtereinsatz mit den Merkmalen nach dem Oberbegriff des Anspruchs 1.The invention relates to a tubular support body for an annular filter insert with the features according to Preamble of claim 1.
Aus der DE-OS 39 21 369 ist ein derartiger Stützkörper für patronenförmige Filterelemente bekannt, der unterschiedli che Perforierungen aufweist, um ein Durchströmen der zu filternden Flüssigkeit zu ermöglichen. Der Stützkörper kann entweder als innerer oder äußerer Stützkörper für das Fil terelement verwendet werden.From DE-OS 39 21 369 such a support body for cartridge-shaped filter elements known, the differ che perforations to flow through the to allow filtering liquid. The support body can either as an inner or outer support body for the fil terelement can be used.
Nachteilig an einem derartigen Stützkörper ist, daß das Filterelement mit seinen Faltkanten nur lose am Stützkörper anliegt, wodurch insbesondere bei großen Differenzdrücken eine schädliche Faltenbewegung und ein Kollabieren des Fil terelementes hervorgerufen und somit die Stabilität des Filtereinsatzes und dessen Funktionsfähigkeit gestört wird.A disadvantage of such a support body is that Filter element with its folded edges only loosely on the support body is present, which is particularly the case with large differential pressures harmful wrinkle movement and collapse of the fil terelementes caused and thus the stability of the Filter insert and its functionality is disrupted.
Vorliegende Erfindung beschäftigt sich daher mit dem Pro blem, auf konstruktiv einfache Weise einen Stützkörper zu finden, bei der eine Faltenbewegung vermieden wird, so daß die Stabilität des Filtereinsatzes und dessen gewünschte Funktion gewährleistet ist.The present invention is therefore concerned with the pro blem, a support body in a structurally simple manner find in which a wrinkle movement is avoided, so that the stability of the filter insert and its desired Function is guaranteed.
Gelöst wird dieses Problem mit einem rohrförmigen Stützkör per mit den Merkmalen nach dem Kennzeichen des Anspruchs 1.This problem is solved with a tubular support body per with the features according to the characterizing part of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Un teransprüchen enthalten. Advantageous embodiments of the invention are in the Un claims included.
Zum Stand der Technik ist noch auf die DE-AS 22 27 378 hin zuweisen, aus der ein Filtereinsatz bekannt ist, bei dem ein flexibel verformbarer Träger vorgesehen ist, an dem nach außen abstehende Reihen von Fingern angeordnet sind, die in Falten des Faltenfilterelementes eingreifen und die ses gespreizt halten. Hierfür ist einerseits eine aufwendi ge Konstruktion des Trägers notwendig und andererseits ist der Zusammenbau von Filterelement und Träger kompliziert und aufwendig.The state of the art is still based on DE-AS 22 27 378 assign from which a filter insert is known in which a flexibly deformable support is provided on which rows of fingers protruding outwards are arranged, which engage in folds of the pleated filter element and which keep it spread. On the one hand, this is a complex ge construction of the carrier is necessary and on the other hand the assembly of the filter element and carrier complicated and expensive.
Die Erfindung ist nachstehend in zwei Ausführungsbeispielen anhand der Zeichnung näher beschrieben.The invention is in two embodiments below described in more detail with reference to the drawing.

Ein rohrförmiger Stützkörper 1 aus Kunststoff - hier als Innenzarge ausgebildet - für einen radial durchströmten ringförmigen Filtereinsatz mit sternförmig gefaltetem Fil terelement aus einer gefalteten Filterpapierbahn besteht aus axial beabstandeten umlaufenden Stützringen 2, die über auf dem Umfang verteilte Längsrippen 3 miteinander verbun den sind. Zur Stabilisierung und Lagefixierung des Filter elementes sind auf der äußeren Stirnseite der Stützringe als flache Profilierung 4 ausgebildete Längsrillen 5 vorge sehen, die die in Längsrichtung verlaufenden Faltkanten des Filterelementes in Umfangsrichtung gesehen formschlüssig über eine gewisse geringe Höhe umfassen. Die Profilierung 4 ist beispielhaft als bogenförmige Längsrillen 5 ausgeführt, wobei die Anzahl der Längsrillen 5 in Umfangsrichtung gese hen der Anzahl der Faltkanten des Filterelementes ent spricht.A tubular support body 1 made of plastic - here designed as an inner frame - for a radially flowed ring-shaped filter insert with a star-shaped fil terelement from a folded filter paper web consists of axially spaced circumferential support rings 2 , which are connected to one another via circumferential longitudinal ribs 3 . To stabilize and fix the filter element are seen on the outer end face of the support rings as a flat profile 4 formed longitudinal grooves 5 , which include the longitudinally extending fold edges of the filter element seen in the circumferential direction positively over a certain small height. The profiling 4 is designed, for example, as an arcuate longitudinal groove 5 , the number of longitudinal grooves 5 in the circumferential direction being the number of folded edges of the filter element.
Das Ausführungsbeispiel gemäß Fig. 4-6 unterscheidet sich von dem gemäß Fig. 1-3 dadurch, daß zusätzlich an die Längsrippen 3 schwertförmige Leisten 6 einstückig angeformt sind, die jeweils in eine offene Falte des Filterelementes eingreifen, um dieses zusätzlich zu stabilisieren. Zur Ge wichtserleichterung können die Leisten 6 mit Ausnehmungen 7 versehen sein. Um die Filtrationsfläche des Filterelementes nicht unnötigerweise zu verringern, können die Leisten 6 mit als Abstandshalter dienenden Nocken 8 versehen sein, wie sie beispielsweise von Filterelementen mit Papierprä gung her bekannt sind.The embodiment of FIGS. 4-6 differs from that according to FIGS. 1-3 in that in addition sword-shaped to the longitudinal ribs 3 strips are formed integrally 6, each of which engages in an open fold of the filter element to stabilize in addition to this. To Ge weight relief, the strips 6 can be provided with recesses 7 . In order not to unnecessarily reduce the filtration area of the filter element, the strips 6 can be provided with cams 8 serving as spacers, as are known, for example, from filter elements with paper embossing.
Außerdem kann die Leiste 6 in Längsrichtung des Stützkör pers 1 gesehen segment- oder kammartig ausgebildet sein.In addition, the bar 6 can be seen in the longitudinal direction of the Stützkör pers 1 segment or comb-like.
Gemäß Fig. 4 weisen die Stützringe 2 auf der linken Zeich nungshälfte einen anderen Querschnitt als auf der rechten Zeichnungshälfte auf. Mit den U-förmigen Stützringen 9 (ge mäß rechter Zeichnungshälfte Fig. 4) wird mit geringem Ma terialaufwand ein Maximum an Festigkeit erreicht.According to Fig. 4 2, the support rings on the left half of Drawing drying a different cross section than on the right half of the drawing on. With the U-shaped support rings 9 (according to the right half of the drawing Fig. 4) maximum material strength is achieved with little Ma.
Mit den aufgezeigten Ausführungen wird auf konstruktiv ein fache Weise ein Stützkörper für ein sternförmig gefaltetes Filterelement eines radial durchströmten Ringfilters für Flüssigkeiten geschaffen, bei dem ein geringer Durchflußwi derstand erreicht und ein Kollabieren des Filterelementes im Bereich der Innenzarge sowie eine Faltenbewegung verhin dert wird.With the shown designs is a constructive fold way a support body for a star folded Filter element of a radially flowed ring filter for Liquids created in which a low Durchwi reached and a collapse of the filter element in the area of the inner frame as well as a fold movement is changed.
