Abstract

An adsorption filter for use in motor vehicles or in dust-proof work cabins consists of a frame, made of an elastomer or plastic foam, which is filled with a chemical adsorbent agent, such as calcium aluminium silicate. The sorptive material can be held between permeable foam layers on both faces. In case of intense vibration, the active area can be subdivided into small cells. Such filters can be readily adapted to difficult shapes of the air ducts. They retain their sorptive capacity throughout the whole section.

Description

Beschreibung und Erläuterung zur Patent- und Hilfsgebrauchsmusteranmeldung 'Sorptionsfilter' Es ist bekannt, Chemisorptionsmassen in Behälterformen anzulagern, durch die man zu reinigende Luft durchbläst oder durchsaugt. Die Verunreinigungen bleiben an den Chemisorptionsmassen haften.Description and explanation of the patent and utility model registration 'Sorption filter' It is known to store chemisorption masses in container shapes, through which air to be cleaned is blown or sucked through. The impurities remain attached to the chemisorption masses.

Es ist weiterhin bekannt, zur Abscheidung von Dämpfen, die z. Bo mit Verunreinigungen zusätzlich belastet sind, Sorptionsmassen, die in Behältern oder zwischen Tüchern eingelagert sind, zu verwenden. Der Nachteil dieser Bauweisen liegt begründet in der schwierigen Form des Anpassens und bei den begrenzenden Tüchern im Verrütteln der Chemisorptionsmassen, die in bewährten Räumen zur Chemisorption eingebaut sind, wie z. B. in Arbeitsschutzkabinen, Kraftfahrzeugen oder dergleichen.It is also known for the separation of vapors that z. Bo with Contaminants are additionally contaminated, sorption masses in containers or are stored between cloths. The disadvantage of these designs is due to the difficult form of fitting and the limiting drapes in shaking the chemisorption masses, which are used in proven rooms for chemisorption are installed, such. B. in work safety cabins, motor vehicles or the like.

Erfindungsgemäß soll die Sorptionsrnasse am Verrütteln gehindert werden, damit in jedem Punkt des Filterteiles gleiche Widerstände und somit die gleiche Sorptionsverfügbarkeit erhalten ist.According to the invention, the sorption mass is to be prevented from shaking, thus the same resistances and thus the same in every point of the filter part Sorption availability is preserved.

Die Arretierung der Massen und die flexible Anpassungsfähigkeit an die unterschiedlichsten Formteile von Ansaugkanälen und dergleichen für die unterschiedlichsten Formen werden erfindungsgemäß dadurch gewährleistet, indem man flexiblen Kunststoff, vorzugsweise groP,oorigen Schaum stoff, wählt, der die Mantelbewährung des Sorptionsfilters darstellt, und die mehrere mm oder cm starke Sorptionsschicht selber, in vorzugsweise flexiblen durch Stücke abgeteilten Kleinzellen, in ein Flächengebilde eingelagert wird Diese erfinduncrsgemäße Bauweise ist in der beiliegenden Zeichnung dargestellt.The locking of the masses and the flexible adaptability to it the most varied of molded parts of intake ducts and the like for the most varied Shapes are guaranteed according to the invention by using flexible plastic, preferably large, porous foam, which will prove the worth of the jacket of the sorption filter represents, and the several mm or cm thick sorption layer itself, in preferably flexible small cells divided by pieces, embedded in a flat structure This construction according to the invention is shown in the accompanying drawing.

In der beiliegenden Zeichnung ist dargestellt; mit 1 der Mantelrahmen eines Sorptionsfilters mit 2 die dichtende Randbewähruna, vor«.ugsweise aus abdichtendem, flexiblem Material, wie Gummi, Schaumstoff oder dergleichen mit 3 + 4 die atmungsaktiven Deckschichten, z. B. bestehend aus porösem Kuns'stoff oder Vliesfiltermaterial mit 5 die zellenförmigen Abgrenzungen mit 6 die eingelagerten Sorptionsmassen, z. B. Calciumaluminiumsilikat Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen darcestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, als Sorptionsfilter einen elastischen Körper in Form eines Rahmens zu verwenden, z. Bo aus Gummi oder Kunststoff gefertigt, in dem zellenförnige Abgrenzungen aus elastischem Material eingearbeitet sind, die mit atmungsaktiven Deckschichten überlagert sind und die dazwischen eingelagerten Chemisorptionsmassen elastisch arretieren weiterhin kann die Arretierung insbesondere bei stärkeren Sorptionsfiltern durch atmung#aktivem, porösem Schaumstoff geschaffen werden, der die Sorptionsmassen iteinander atrnungsaktiv verbindet.In the accompanying drawing is shown; with 1 the coat frame a sorption filter with 2 the sealing edge proof, preferably from sealing, flexible material such as rubber, foam or the like with 3 + 4 the breathable Top layers, e.g. B. consisting of porous Kuns'stoff or fleece filter material with 5 the cellular boundaries with 6 the embedded sorbent masses, e.g. B. Calcium aluminum silicate Of course, the invention is not limited to the above the forms of training shown and described in detail, but rather numerous changes are possible without, however, deviating from the basic idea, to use an elastic body in the form of a frame as a sorption filter, z. Bo made of rubber or plastic, in which cellular boundaries are made elastic material are incorporated, which are superimposed with breathable top layers and elastically lock the chemisorption masses stored in between Furthermore, the locking can be achieved, especially with stronger sorption filters breathing # active, porous foam can be created, which the sorption masses with each other actively connects.

Bei kleinerm Filtern können die Stege wegfallen, und luftdurchlässige, poröse Schaumstoffe können die Sorptionsmassen miteinander genügend fest verlagern Patent- und HilfscebrauchsmusteranstruchWith smaller filters, the bars can be omitted, and air-permeable, porous foams can move the sorption masses together with sufficient strength Patent and utility model claims
