Description

Für Sonderzwecke kann es wertvoll sein, Filtereinsätze für> Gasschutzmasken derartig zu bauen, daß sie in einer Richtung möglichst geringe Ausmaße haben, also flach sind wie etwa eine Schuhkrem@dose. Körnige gasbindende Stoffe, insbesondere Aktivkohle, lassen sich aber nicht für beliebig niedrigen Schichten verwenden, selbst wenn man die Oberfläche der Schichten sehr groß wählt,- da bei zu niedrigen Schichten; keine einwandfreie Wechselwirkung zwischen der durch Gase verunreinigten Luft und den gasbindenden Stoffen stattfindet.For special purposes it can be valuable to build filter inserts for> gas protective masks in such a way that they are as small as possible in one direction, that is, they are flat like a shoe cream box. Granular gas-binding substances, in particular activated carbon, cannot be used for any low layers, even if the surface of the layers is chosen to be very large, because if the layers are too low; there is no perfect interaction between the air polluted by gases and the gas-binding substances.

Die Erfindung besteht nun darin, daß in dem als flache Dose ausgebildeten Einsatz körnige gasbindende Stoffe, z. B. Aktivkahle, in zwei oder mehr nebeneinander oder, umeinander angeordneten niedrigen Schichten derart angeordnet sinrd, daß der zu reinigende Luftstrom sie nacheinander durchströmt und mindestens einmal um r8b° umgeleitet wird.The invention consists in that in the designed as a flat can Use of granular gas-binding substances, e.g. B. Activated Kahle, in two or more side by side or, low layers arranged around one another are arranged in such a way that the The air flow to be cleaned flows through them one after the other and at least once by r8b ° is diverted.

Verwendet man neben den körnigen gasbindenden. Schichten noch eine andersartige Luftreinigungsschicht, so wird diese erfindungsgemäß neben den körnigen gasbindenden Stoffen oder um die körnibgen .gasbindenden Stoffe herum oder unter oder über diesen derart angeordnet, daß der zu reinigende Luftstrom sämtliche Schichten nacheinander durchströmt.Is used in addition to the granular gas-binding. One more layers different air-cleaning layer, this is according to the invention in addition to the granular gas-binding substances or around or under the granular .gas-binding substances or arranged above these in such a way that the air stream to be cleaned covers all layers flows through one after the other.

Die andersartige Schicht ist vorteilhaft um den in den Filtereinsatz versenkten Gewind.eanschluß herum untergebracht, weil dadurch wesentlich an Bauhöhe gespart wird.The different layer is advantageous around the one in the filter element Recessed thread connection housed around it, because it is significantly higher in height is saved.

Es ist natürlich auch möglich, den Platz der andersartigen Schicht gegebenenfalls mit -einer der anderen Schichten zu, vertauschen.It is of course also possible to replace the layer of a different type if necessary swap with one of the other layers.

Inder Zeichnung sind einigeAusführu gsformen des neuem Einsatzfilters dargestellt. Bild z stellt einen Längsschnitt und eine Aufsicht eines Filters aus nebeneinanderliegenden Schichten aus körnigen gasbindenden Stoffen I dar, die nacheinander in der Pfeilrichtung von der zu reinigenden Luft durchströmt werden.Some embodiments of the new insert filter are shown in the drawing shown. Image z shows a longitudinal section and a top view of a filter adjacent layers of granular gas-binding substances I represent, one after the other the air to be cleaned flows through in the direction of the arrow.

Bild 2 zeigt einen Filtereinsatz im Längsschnitt und in der Aufsicht, bei dem die körnigen gasbindenden Schichten I konzentrisch angeordnet sind. , Bei der AuGführungsform nach Eil,d@ 3 ist noch eine, andersartige Luftreinigungsschicht II in dem Filter untergebracht, -die neben den übrigen Schichten I liegt. Auch hierbei werden. sämtliche Schichten in. der Pfeilrichtung von der zu reinigenden Luft durchströmt.Figure 2 shows a filter insert in longitudinal section and in top view, in which the granular gas-binding layers I are arranged concentrically. , At the embodiment according to Eil, d @ 3 is another, different air-cleaning layer II housed in the filter, which is next to the other layers I. Here too will. The air to be cleaned flows through all layers in the direction of the arrow.

Wie Bild q. zeigt, kann die andersartige Schicht II aber auch unter oder neben. einer körnigen. gasbindenden Schicht I liegen. Sie kann natürlich auch darüber angeordnet sein.Like picture q. shows, the different layer II can also be under or next to. a grainy one. gas-binding layer I lie. Of course you can too be arranged above.

Bild 5 zeigt eine Ausführungsform, bei der entweder eine Schicht aus körnigen. gasbindenden Stoffen oder eine Schicht aus einer andersartigen Luftreinigungsmasse -um den, versenkt in, der Filterbüchse liegenden Gewindeanschlußstutzen herum untergebracht ist.Figure 5 shows an embodiment in which either a layer of grainy. gas-binding substances or a layer of another type of air-purifying compound - Housed around the, sunk in, the filter sleeve lying threaded connection piece is.
