Description

Die Erfindung betrifft eine Filterpatrone für einen Gasfilter, insbesondere Luftfilter für die Entstaubung, nach dem Oberbegriff des Anspruchs 1.The invention relates to a filter cartridge for one Gas filters, in particular air filters for dedusting, according to the preamble of claim 1.

Eine derartige Gasfilterpatrone ist aus der EP 01 60 168 B1 bekannt, bei der ein sternförmig gefaltetes Filterelement ein sternförmig gefaltetes Stützgitter aus Drahtgewebe umgibt. Um das Filterelement gegen das Stützgitter vorzuspannen sind Drahtstreben vorgese­ hen, die entlang der inneren Faltenrücken des Filterele­ mentes von außen anliegen und mit den Endkappen fest verbunden sind. Nachteilig an dieser Ausführung ist die Vielzahl der Einzelteile und der notwendig große Auf­ wand bei der Herstellung der Filterpatrone.Such a gas filter cartridge is from EP 01 60 168 B1 known, in which a star folded Filter element made of a star-shaped support grid Wire mesh surrounds. To the filter element against that Wire struts are pre-tensioned to support the grids hen that along the inner fold back of the Filterele Fit the mentes from the outside and secure with the end caps are connected. The disadvantage of this version is that Large number of individual parts and the necessary large size wall in the manufacture of the filter cartridge.

Aufgabe der vorliegenden Erfindung ist es daher, bei einer Filterpatrone eines Gasfilters die Verbindung zwischen Filterelement und Stützgitter auf konstruktiv einfache Weise so zu gestalten, daß bei der Abreinigung des Filterelementes nach dem Gegenstromprinzip das Filterelement einerseits genügend Bewegungsfreiheit hat und andererseits sich nicht vom Stützgitter loslöst und beschädigt wird.The object of the present invention is therefore at the connection of a filter cartridge of a gas filter between filter element and support grid on constructive easy to design so that when cleaning the filter element according to the counterflow principle On the one hand, filter element sufficient freedom of movement and on the other hand does not detach from the support grid and is damaged.

Gelöst wird diese Aufgabe mit einer Filterpatrone mit den Merkmalen nach dem Kennzeichen des An­ spruchs 1.This task is solved with a filter cartridge with the characteristics after the identification of the contractor saying 1.

Weitere Ausgestaltungen nach der Erfindung sind in den Unteransprüchen enthalten.Further refinements according to the invention are in contain the subclaims.

Ein Ausführungsbeispiel wird nachfolgend anhand der Zeichnung, die skizzenhaft ein Filterelement mit Stützgitter in Teilansicht darstellt, näher erläutert.An exemplary embodiment is described below the drawing, which is sketchy using a filter element Support grid in partial view, explained in more detail.

Eine zylindrische Filterpatrone für beispielsweise ei­ nen Luftfilter zur Entstaubung staubhaltiger Räume be­ steht aus einem sternförmig gefalteten Filterelement 1 aus Filtervliesmaterial, das ganzflächig an einem ent­ sprechend sternförmig gefalteten Stützgitter 2 aus ei­ nem Drahtgewebe anliegt, wobei das Filterelement 1 von außen 3 nach innen 4 durchströmt wird, so daß sich der Staub auf dem Filterelement 1 außen ablagert. Bei der Abreinigung des Filterelementes I wird dieses in umgekehrter Strömungsrichtung mit einem Drucklufts­ trom von innen 4 nach außen 3 beaufschlagt, so daß sich der am Filterelement 1 außen angesammelte Staub ab­ löst und in bekannter Weise entfernt werden kann. Um hierbei einerseits dem Filterelement 1 genügend Bewe­ gungsfreiheit zu lassen und es andererseits gegen ein Lösen vom Stützgitter 2 zu bewahren, ist das Filterele­ ment 1 auf seinen inneren Faltenrücken 5 jeweils ab­ schnittsweise linienförmig mit dem Stützgitter 2 ver­ klebt 6. Die Verklebung 6 kann je nach Vorgabe entlang des Faltenrückens 5 unterbrochen oder durchgängig er­ folgen, wobei eine Klebstoffraupe von innen 4 auf das Stützgitter 2 zwischen die Drahtgewebemaschen hin­ durch zur Anlage an das Filtervlies aufgebracht wird.A cylindrical filter cartridge for, for example, an air filter for dedusting dusty rooms is made of a star-shaped filter element 1 made of filter non-woven material, which rests over the entire surface of a corresponding star-shaped support grid 2 made of a wire mesh, the filter element 1 flowing through from the outside 3 to the inside 4 is, so that the dust is deposited on the filter element 1 outside. When cleaning the filter element I, this is applied in the reverse flow direction with a compressed air flow from the inside 4 to the outside 3 , so that the dust accumulated on the filter element 1 on the outside loosens and can be removed in a known manner. In order to make this one hand, the filter element 1 sufficiently BEWE supply freedom and to keep it on the other hand against disengagement from the support grid 2, the Filterele element 1 on its inner pleat tips 5 each from sectionally linear manner with the support grid 2 ver sticks. 6 The gluing 6 can be interrupted or continuous, depending on the specification, along the fold back 5 , an adhesive bead being applied from the inside 4 to the support grid 2 between the wire mesh meshes by contacting the filter fleece.

Bei der Verwendung eines Filterelementes aus Kunst­ stoffmaterial und eines Stützgitters aus Kunststoff kann die Verbindung beispielsweise auch durch Ultraschall­ schweißen erfolgen, wobei Filterelement und Stützgit­ ter an den entsprechenden Stellen miteinander ver­ schmelzen.When using a filter element made of art material and a plastic support grid the connection, for example, also by ultrasound welding take place, with filter element and support grid ver at the appropriate points melt.

Mit einer derartig konstruktiv einfachen Verbindung zwischen Stützgitter und Filterelement auf begrenztem Raum ist bei der Druckluft-Abreinigung im Gegen­ strom gewährleistet, daß das Filterelement sich nicht vom Stützgitter löst, jedoch soviel Bewegung zuläßt, um den angesammelten Staub vom Filtervlies zu lösen.With such a constructively simple connection between support grid and filter element on limited In compressed air cleaning, space is in the opposite current ensures that the filter element is not detaches from the support grid, but allows as much movement to loosen the accumulated dust from the filter fleece.

Bei der Verwendung einer rohrförmigen Innenzarge (angedeutet bei 7) aus Kunststoff könnte die Verbin­ dung eines auf Kunststoff basierenden Filterelementes direkt mit der Innenzarge 7, beispielsweise durch Ultra­ schallverschweißung des Faltenrückens 5 des Filterele­ mentes mit der Innenzarge 7, erfolgen, so daß auf ein Stützgewebe eventuell verzichtet werden kann.When using a tubular inner frame (indicated at 7) made of plastic, the connec tion of a plastic-based filter element could be made directly to the inner frame 7 , for example by ultrasonically welding the pleated back 5 of the filter element with the inner frame 7 , so that on a supporting fabric can possibly be dispensed with.
