FILTERZELLENRAHMENFILTER CELL FRAME
Die Erfindung bezieht sich auf einen Filterzellenrahmen zur Fixierung von plissiertem Filtermedium, Das zur Vergrößerung der Filterfläche plissierte Filtermedium wurde bisher in Filterzellenrahmen durch besondere kammartige Einlagen in den Rahmenteilen selbst und in Form von Verstrebungen,·, die sich über die Filterfläche verteilten, gehalten. Die Einlagen bzw, Verstrebungen bestanden zum größten Teil aus Pappe mit kammartigen Einschnitten, Sie dienten dazu, die spitzwinklige Faltung des Filtermediums gegenüber dem zu reinigenden Luftstrom, insbesondere bei mehr oder weniger großer Filterfläche, abzustützen, Obschon diese Art, das Filtermedium in Filterzellen anzuordnen und zu befestigen, eine praktikable Lösung darstellte, hat sieaber den Nachteil, daß das Einlegen des Filtermediums in die Pappeinlagen und Verstrebungen eine zeit- und damit kostenaufwendige Handarbeit ist. Sie führt zu einer nicht unerheblichen Verteuerung der Filterzellen,The invention relates to a filter cell frame for fixing pleated filter medium, which is used to enlarge the Filter surface pleated filter medium was previously in filter cell frames by special comb-like inserts in the frame parts themselves and in the form of struts, · that extend over the Distributed filter surface, held. The deposits or struts consisted mostly of cardboard with comb-like incisions, They were used to create the acute-angled folds of the filter medium compared to the air flow to be cleaned, especially if there is more or less large filter area to be supported, although this way of arranging and fixing the filter medium in filter cells is a represented a practicable solution, it has the disadvantage that inserting the filter medium into the cardboard inlays and struts is a time-consuming and therefore costly manual work. It leads to a not inconsiderable increase in the price of the filter cells,
Die Erfindung hat sich die Aufgabe gestellt, die Mittel, die zur Herstellung einer Filterzelle benötigt- werden„ zu vereinfachen, um dementsprechend den Zusammenbau weniger zeitaufwendig vornehmenThe invention has the task of providing the means for Production of a filter cell needed to be "simplified, in order to make the assembly less time consuming accordingly

zu können· Die Lösung der Aufgabe besteht bei einem Filterzellen-' rahmen mit Abstandhalter zur Aufnahme von plissiertem Filtermedium darin, daß die an gegenüberliegenden Rahmenteilen vorgesehenen Abstandhalter mit dem Rahmen aus einem Stück bestehen. Nach einer bevorzugten Ausführungsform sind die Abstandhalter im Vacuumziehverfahren dem Rahmen angeformt, und zwar in der Gestalt eines dreieckigen Hohlkörpers. Für den Fall, daß der Rahmen zusätzlich mit einem Deckel versehen ist, sind an diesem ebenfalls dreieckige Abstandhalter so vorgesehen, daß ihre Spitzen zum Rahmen entgegengesetzt gerichtet sind und die Abstandhalter beim Aufsetzen des Deckels auf den Rahmen unter Zwischenlage des Filtermediums zahnkammartig ineinandergreifen. Zur Erhöhung der Stabilität kamt das Filtermedium an den Abstandhaltern noch zusätzlich durch Kleben oder Schweißen befestigt werden.to be able to solve the problem with a filter cell ' frame with spacer for receiving pleated filter medium in that the provided on opposite frame parts Spacers with the frame consist of one piece. According to a preferred embodiment, the spacers are vacuum-drawn molded onto the frame, in the shape of a triangular hollow body. In the event that the frame additionally is provided with a lid, triangular spacers are also provided on this so that their tips are opposite to the frame are directed and the spacers when the cover is placed on the frame with the interposition of the filter medium in the manner of a tooth comb interlock. That came to increase the stability Filter medium can also be attached to the spacers by gluing or welding.
In der Zeichnung ist der Gedanke der Erfindung an einem Ausführungsbeispiel wiedergegeben. Die Figur zeigt eine schaubildliche Ansicht auf eine Filterzelle, die teilweise geschnitten ist.In the drawing, the idea of the invention is reproduced using an exemplary embodiment. The figure shows a perspective view on a filter cell that is partially cut.
Der Filterzellenrahmen besteht aus dem eigentlichen Rahmen 1 und dem auf diesen von oben aufgeschobenen Deckel 2. Rahmen 1 und Deckel 2 besitzen an gegenüberliegenden Seiten in die Filterfläche hineinragende Abstützborde 3»4» die das plissierte Filtermedium 5 im Rahmen 1 und Deckel 2 gegen Herausfallen sichern. Für die Fixierung der Falten des Filtermediums 5 sind in den gegenüberliegenden Längsseiten vom Rahmen 1 und Deckel 2 Abstandhalter 6,7The filter cell frame consists of the actual frame 1 and the cover 2 pushed onto it from above. Frame 1 and Lids 2 have support rims 3 »4» which project the pleated filter medium 5 on opposite sides into the filter surface Secure in frame 1 and cover 2 against falling out. For the fixation of the folds of the filter medium 5 are in the opposite Long sides of frame 1 and cover 2 spacers 6.7

vorgesehen, die gemäß der Erfindung mit den Rahmen- bzw* Deckelteilen aus einem Stück bestehen und die Gestalt eines Hohlkörpers haben. Nach einer bevorzugten Ausführungsform sind die Hohlkörper als spitzwinklige Dreiecke ausgebildet, die bei auf dem Rahmen 1 aufgeschobenen Deckel 2 ihre Spitzen entgegengesetzt gerichtet haben und dabei praktisch zahnkammartig ineinandergreifen» Das Filtermedium 5, das zickzackartig zwischen den Dreiecken 6,7 verläuft, ist dann sowohl von der Luftan- wie auch von der Luftabströmseite gegen jede Möglichkeit des Heraustretens oder des Herausdrückens aus dem Rahmen 1 und Deckel 2 gesichert. Erscheint eine so hohe Sicherung bei bestimmten Betriebsbedingungen der Filterzelle nicht notwendig, genügt es auch, wenn nur im Rahmen 1 dreieckige Abstandhalter 6 vorgesehen werden. Die Filterzelle würde dann so eingebaut, daß die Spitzen der Abstandhalter 6 gegen den Luftstrom gerichtet sind.provided, which according to the invention with the frame or * cover parts consist of one piece and the shape of a hollow body to have. According to a preferred embodiment, the hollow body are designed as acute triangles that are on the Frame 1 pushed-on cover 2 opposite their tips have directed and practically mesh with one another like a tooth comb » The filter medium 5, the zigzag between the triangles 6.7 runs, is then from both the air inlet and the air outlet side secured against any possibility of stepping out or being pushed out of the frame 1 and cover 2. Appears such a high level of security under certain operating conditions of the filter cell not necessary, it is also sufficient if only triangular in the frame 1 Spacers 6 are provided. The filter cell would then installed so that the tips of the spacers 6 against the Airflow are directed.
Ein weiteres Merkmal der Erfindung ist, daß die Abstandhalter den Rahmen- bzw. Deckelteilen im Vacuumziehverfahren angeformt sind. Zur Verbesserung der Stabilität kann das Filtermedium 5 mit den Abstandhaltern 6,7 fest verbunden werden, und zwar durch Kleben oder Schweißen·Another feature of the invention is that the spacers The frame or cover parts are formed using the vacuum drawing process are. To improve the stability, the filter medium 5 be firmly connected to the spacers 6.7, namely through Gluing or welding
