Abstract

The invention describes a concertina filter which is characterised in that it is shipped in the shipping form as a package compressed together and is used in the working area unfolded and in this case releases the influx and efflux surfaces in accordance with flow, the support points being made impermeable at the same time.

Description

Es ist bekannt, Raumluftreinigungsgeräte mit staubabscheiden­ den Filtern oder Chemiefiltern zu versehen.It is known to separate air cleaning devices with dust the filters or chemical filters.

Das Verpacken und der Einsatz von Chemiefiltern ist kosten­ aufwendig.Packing and using chemical filters is expensive complex.

Hinzu kommt, daß die Filterflächen bei der nicht verformten Paketfilteranordnung in der Regel zu klein sind und einen zu hohen Widerstand bedeuten.In addition, the filter surfaces are not deformed Packet filter arrangements are usually too small and too high resistance.

Aus diesem Grunde ist vielfach versucht worden, Zick-Zack- Filter oder Trapez-Filter zu verwenden, um die Anströmfläche so klein wie möglich zu halten.For this reason, many attempts have been made to zigzag Filters or trapezoidal filters to use on the inflow surface to keep it as small as possible.

Um einen vorgefertigten Filter in kleinster Verpackungsbau­ weie zum Versand bringen zu können und trotzdem nach dem Einbau den größtmöglichen Anströmflächenfilter zu benutzen, wird erfindungsgemäß vorgeschlagen, einen Ziehharmonika- Filter zu verwenden, der, wie in der Abb. A zu sehen ist, zusammengedrückt als Paket versandfähig ist und, wie in Abb. B dargestellt, im Arbeitszustand auseinandergezogen ist. In order to be able to ship a prefabricated filter in the smallest packaging construction and still use the largest possible inflow surface filter after installation, the invention proposes using an accordion filter which, as can be seen in FIG. A , is compressed as a package is ready for dispatch and, as shown in Fig. B , pulled apart in working condition.

Dabei sind erfindungsgemäß, wie mit Pfeilen C bezeichnet, die Anströmflächen aus einem gasundurchlässigen Material an den Auflagepunkten kaschiert und die Öffnungen, z. B. spitzwinke­ lig dargestellt, sind perforiert und mit D bezeichnet.According to the invention, as indicated by arrows C , the inflow surfaces made of a gas-impermeable material are laminated at the support points and the openings, for. B. acute angles lig are perforated and labeled D.

Hierdurch wird die An- und Abströmseite wesentlich größer als bei einem flachen Filter und die absolute gleichmäßige Schichtstärke, die das Durchströmen der zu reinigenden Luft­ massen gewährleistet.This makes the inflow and outflow side much larger than a flat filter and the absolute even Layer thickness, the flow through the air to be cleaned mass guaranteed.

Claims (1)

Ziehharmonika-Filter, dadurch gekennzeichnet, daß er in Ver­ sandform als Paket zusammengedrückt versandt wird und im Arbeitsbereich, wie aus der Abb. B ersichtlich, aus­ einandergezogen Anwendung findet und dabei die An- und Ab­ strömflächen strömungsgerecht freigibt, wobei gleichzeitig die Auflegepunkte D undurchlässig ausgebildet sind.Accordion filter, characterized in that it is shipped in compressed sand as a package and in the work area, as can be seen in Fig. B , is used from one another and thereby releases the inflow and outflow surfaces in accordance with the flow, while at the same time imposing points D impermeable are trained.
