Abstract

A gas dust filter insert has a star-shaped supporting frame and insert and end plates enclosing the open folds. The novelty is that the star-shaped folded filter insert ridges are firmly secured in lines or points to the supporting frame. Pref. the ridges on the filter insert are secured to the supporting frame by glue or melting/cooling. Only the inner faces of the filter insert ridges are glued to the supporting frame. The glue may be applied in a dotted or continuous line. A filter insert made of plastic fleece may be attached to the frame by spot welding with a heat gun. USE/ADVANTAGE - The filter removes dust from gas in general industrial applications when the filter is cleaned from time to time. During cleaning with reverse flow compressed air, the attachment of filter insert locking on the ridges enables the rest of the filter to flex and loosen dust, to regenerate the filter without detaching from the frame.

Description

Die Erfindung betrifft eine Filterpatrone für einen Gasfilter, insbesondere Luftfilter für die Entstau­ bung, nach dem Oberbegriff des Anspruchs 1.The invention relates to a filter cartridge for one Gas filters, especially air filters for congestion Exercise, 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 vorge­ sehen, die entlang der inneren Faltenrücken des Fil­ terelementes von außen anliegen und mit den Endkappen fest verbunden sind. Nachteilig an dieser Ausführung ist die Vielzahl der Einzelteile und der notwendig große Aufwand 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 a star-shaped support grid surrounded by wire mesh. To counter the filter element wire supports are pre-tensioned see that along the inner fold back of the fil Terelementes from the outside and with the end caps are firmly connected. A disadvantage of this version is the multitude of items and necessary great effort in the manufacture of the filter cartridge.

Problem der vorliegenden Erfindung ist es daher bei einer Filterpatrone eines Gasfilters, die Verbindung zwischen Filterelement und Stützgitter auf konstruk­ tiv einfache Weise so zu gestalten, daß bei der Ab­ reinigung des Filterelementes nach dem Gegenstrom­ prinzip das Filterelement einerseits genügend Bewe­ gungsfreiheit hat und andererseits sich nicht vom Stützgitter loslöst und beschädigt wird.It is therefore a problem of the present invention a filter cartridge of a gas filter, the connection between filter element and support grid on construct tiv simple way to design so that the Ab cleaning the filter element after counterflow principle the filter element on the one hand enough movement freedom of movement and on the other hand does not differ from Support grid detaches and is damaged.

Gelöst wird dieses Problem mit einer Filterpatrone mit den Merkmalen nach dem Kennzeichen des Anspruchs. This problem is solved with a filter cartridge with the features according to the characterizing part of the claim.  

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 erläu­ tert.An embodiment is described below with reference to Drawing with a sketchy filter element Support grid represents in partial view, explained in more detail tert.

Eine zylindrische Filterpatrone für beispielsweise einen Luftfilter zur Entstaubung staubhaltiger Räume besteht aus einem sternförmig gefalteten Filterele­ ment 1 aus Filtervliesmaterial , das ganzflächig an einem entsprechend sternförmig gefalteten Stützgitter 2 aus einem Drahtgewebe anliegt, wobei das Filterele­ ment 1 von außen 3 nach innen 4 durchströmt wird, so daß sich der Staub auf dem Filterelement 1 außen ab­ lagert. Bei der Abreinigung des Filterelementes I wird dieses in umgekehrter Strömungsrichtung mit ei­ nem Druckluftstrom von innen 4 nach außen 3 beauf­ schlagt, so daß sich der am Filterelement 1 außen an­ gesammelte Staub ablöst und in bekannter Weise ent­ fernt werden kann. Um hierbei einerseits dem Filter­ element 1 genügend Bewegungsfreiheit zu lassen und es andererseits gegen ein Lösen vom Stützgitter 2 zu be­ wahren, ist das Filterelement 1 auf seinen inneren Faltenrücken 5 jeweils abschnittsweise linienförmig mit dem Stützgitter 2 verklebt 6. Die Verklebung 6 kann je nach Vorgabe entlang des Faltenrückens 5 un­ terbrochen oder durchgängig erfolgen, wobei eine Klebstoffraupe von innen 4 auf das Stützgitter 2 zwi­ schen die Drahtgewebemaschen hindurch zur Anlage an das Filtervlies aufgebracht wird.A cylindrical filter cartridge for, for example, an air filter for dedusting dust-containing rooms consists of a star-shaped filter element 1 made of filter non-woven material, which rests over the entire surface of a correspondingly star-shaped supporting grid 2 made of a wire mesh, the filter element 1 being flowed through from the outside 3 to the inside 4 , so that the dust is deposited on the filter element 1 from the outside. When cleaning the filter element I, this is struck in the reverse flow direction with egg nem compressed air flow from the inside 4 to the outside 3 , so that the dust on the filter element 1 peels off on the outside and can be removed in a known manner. Here, in order enough on the one hand to allow the filter element 1 of movement and on the other hand maintain it against detachment from the support grid 2 to be, the filter element 1 is in each case partially linearly with the support grid 2 adhered to its inner pleat 5 6. The bond 6 may, depending on the specification along the fold back 5 un interrupted or continuous, with an adhesive bead from the inside 4 to the support grid 2 between the wire mesh loops is applied to rest against the filter fleece.

Bei der Verwendung eines Filterelementes aus Kunst­ stoffmaterial und eines Stützgitters aus Kunststoff kann die Verbindung beispielsweise auch durch Ultra­ schallschweißen erfolgen, wobei Filterelement und Stützgitter an den entsprechenden Stellen miteinander verschmelzen.When using a filter element made of art  material and a plastic support grid the connection can also be made using Ultra sonic welding, filter element and Support grid at the corresponding points with each other merge.

Mit einer derartig konstruktiv einfachen Verbindung zwischen Stützgitter und Filterelement auf begrenztem Raum ist bei der Druckluft-Abreinigung im Gegenstrom 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 counterflow ensures that the filter element is not from Support grid loosens, but allows as much movement to loosen the accumulated dust from the filter fleece.

Bei der Verwendung einer rohrförmigen Innenzarge (an­ gedeutet bei 7) aus Kunststoff könnte die Verbindung eines auf Kunststoff basierenden Filterelementes di­ rekt mit der Innenzarge 7 beispielsweise durch Ultra­ schallverschweißung des Faltenrückens 5 des Filter­ elementes 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 connection of a plastic-based filter element di directly to the inner frame 7, for example, by ultrasonically welding the fold back 5 of the filter element with the inner frame 7 , so that possibly on a supporting fabric can be dispensed with.
