Description
Die Erfindung betrifft ein, Ringfilter, das mit gasbindenden Stoffen, insbesondere gekörnter Aktivkohle, beschickt und namentlich für Schutzraumbelüfter bestimmt ist, und bei dem auf der Filtermasse ein in seiner Höhenlage verschiebbarer Ringdeckel liegt, der unter der Wirkung mehrerer, in einen darüber angeordneten festen Deckel eingebauter Federn ständig auf , die Filtermasse drückt. Dadurch soll vermieden werden, daß beim Zusammensinken der Filtermasse infolge von Erschütterungen Kurzschlußwege für die Luft entstehen. .The invention relates to a ring filter that is filled with gas-binding substances, in particular granular activated carbon, charged and specifically for protective space ventilators is determined, and in which on the filter mass a displaceable in its height position Ring cover lies, which is under the action of several, in one arranged above Fixed cover of built-in springs constantly on, the filter mass presses. This is supposed to be avoided that when the filter mass collapses as a result of vibrations Short-circuit paths for the air arise. .
Die Erfindung erstrebt eine weitere Sicherung derartiger Filter gegen Kurzschlüsse und besteht darin, daß der innere Rand des Filterringes unter Vermittlung einer Faltenmanschette aus gasundurchlässigem Gewebe oder einem biegsamen, dünnen Metall gasdicht mit dem inneren Rand des Filtergehäuses verbunden ist. Dadurch wird mit Sicherheit vermieden, daß Luft statt durch die Filtermasse hindurch über die Filtermasse hinweg strömt und so ungereinigt das Filter verläßt.The invention seeks to further secure such filters against Short circuits and consists in that the inner edge of the filter ring under mediation a folded cuff made of gas-impermeable fabric or a flexible, thin one Metal is gas-tight connected to the inner edge of the filter housing. This will certainly avoided that air instead of through the filter mass through the Filter mass flows away and thus leaves the filter uncleaned.
Der bewegliche Deckel kann an seiner Unterseite einen ringförmigen Ansatz oder zwei ringförmige Ansätze tragen, die sich unter der Wirkung der Federn in die Filtermasse eindrücken. Auch dadurch werden Kurzschlußwege der Luft unmöglich gemacht.The movable cover can have an annular shape on its underside Approach or two ring-shaped attachments that extend under the action of springs press into the filter material. This also makes short-circuit paths in the air impossible made.
Der bewegliche Deckel kann aus sehr dünnem Metallblech oder einem anderen gasdichten und schmiegsamen Stoff, ä. B. Gummi mit Gewebeeinlage, bestehen. Bei dieser Bauart lassen sich-diesoeben beschriebenen ringförmigen Ansätze nicht anbringen. Da aber der dünne Deckel sich allen Formänderungen der Oberfläche .der Filtermasse schnell und sicher anpaßt, so sind derartige Ansätze zu diesen Fällen auch nicht notwendig.The movable cover can be made of very thin sheet metal or a other gas-tight and pliable material, e.g. rubber with a fabric insert. With this type of construction, the ring-shaped approaches described above cannot be used attach. However, since the thin cover is subject to all changes in the shape of the surface Filter mass adapts quickly and safely, so are such approaches to these cases also not necessary.
In der Zeichnung ist eine Ausführungsform des neuen Ringfilters dargestellt. Dabei zeigt Abb. i einen senkrechten Schnitt durch den oberen Teil des Ringfilters und Abb. a eine Aufsicht auf den Deckel.The drawing shows an embodiment of the new ring filter. Fig. I shows a vertical section through the upper part of the ring filter and Fig. a is a plan view of the lid.
Das Filtergehäuse besteht aus siebartig gelochten Blechen a, die einen in sich geschlossenen, mit gekörnter Aktivkohle b beschickten Filterring bilden. Die Luft tritt von außen durch die Aktivkohleschicht b hindurch und tritt gereinigt in den Ringhohlraum c ein, aus dem sie in den zu belüftenden Raum strömt. Das Gehäuse ist oben durch einen festen Deckel d abgeschlossen, in dem mehrere Druckfedern e untergebracht sind. Diese Federn drücken auf den beweglichen Deckel f, der unter Vermittlung der Faltenmanschetteg mit dem festen Deckel d gasdicht verbunden ist. Bei der gezeichneten Ausführungsform -sind an der Unterseite des beweglichen Deckels f ringförmige Ansätze h angeordnet, die unter der Wirkung der Federn e in die körnige Filtermasse hineingedrückt werden.The filter housing consists of sieve-like perforated metal sheets a, which form a self-contained filter ring loaded with granular activated carbon b. The air passes from the outside through the activated carbon layer b and, in a purified state, enters the annular cavity c, from which it flows into the space to be ventilated. The housing is closed at the top by a fixed cover d, in which several compression springs e are housed. These springs press on the movable cover f, which is connected to the fixed cover d in a gas-tight manner through the intermediary of the fold cuffs. In the embodiment shown, annular lugs h are arranged on the underside of the movable cover f and are pressed into the granular filter material under the action of the springs e.
