Description

Luftrein igungspatrone Bekanntlich werden zur Bindung von -Kohlensäure und Wasserdampf in Ateinschutzgeräten Luftreinigungspatronen verwendet, die mit gekörntem Alkali gefüllt sind. Diese Chemikalmasse nimmt während des Gebrauchs der Patrone an Umfang zu. Um eine dadurch bedingte Erhöhung des Atemwiderstandes zu verhindern, wird das Alkali auf gewellten Sieben oder ähnlichen Trägern so verteilt, daß in der Patrone gerade oder zickzackförmige, nicht mit Körnern -beschickte Wege oder Kanäle entstehen, die der Luft freien Durchgang gestatten und in denen die Luft an den Alkalikörnern vorbeistreicht und an diese ihre Kohlensäure und ihren Wassergehalt abgibt. Infolge der Reaktionswärme und der aufgenommenen Feuchtigkeit werden die Körner weich und kleben aneinander. Die Schichten der Chemikalmasse sinken zusammen. Dadurch können sich am Rande der Patrone Kurzschlußwege bilden, die der Luft keinen oder nur sehr geringen Widerstand entgegensetzen und so zu einem Durchbruch der Patrone führen, ehe die Chemikalmasse verbraucht ist.Air purification cartridge is known to bind carbonic acid and water vapor used in respiratory protection devices that use air purifying cartridges granular alkali are filled. This chemical mass increases during use of the Cartridge increasing in size. In order to increase breathing resistance as a result prevent, the alkali is distributed on corrugated sieves or similar supports in such a way that that in the cartridge straight or zigzag, not with grain-laden paths or channels arise that allow the air to pass freely and in which the Air sweeps past the alkali grains and their carbonic acid and theirs Gives off water content. As a result of the heat of reaction and the absorbed moisture the grains become soft and stick together. The layers of chemical mass sink together. This can cause short-circuit paths to form at the edge of the cartridge, which the Oppose no or only very little resistance to air and thus lead to a breakthrough the cartridge before the chemical mass is used up.

Die Erfindung besteht nun darin, daß bei einer Luftreinigungspatrone, insbesondere einer Kohlensäureabsorptionspatrone für Atemschutzgeräte, die Faltensiebe zur Aufnahme der Chemikalmasse aufweist, die mit geradlinig, strahlenförmig oder gleichachsig verlaufenden Falten versehenen Siebe am Rande einen ebenen Flansch aufweisen, durch den die Bildung eines Chemikalmantels entlang der Gehäusewand ermöglicht ist.The invention consists in that in an air cleaning cartridge, in particular a carbonic acid absorption cartridge for breathing apparatus, the folding screens for receiving the chemical mass, which is straight, radial or coaxially extending folds provided screens on the edge with a flat flange have, which enables the formation of a chemical jacket along the housing wall is.

Während des Gebrauchs der Patronen bilden sich in diesem der Gehäusewand anliegenden Chemikalmantel so viel weich gewordene und durch Adhäsion an der Blechwand festgehaltene Körner, daß das Auftreten von Kurzschlußwegen unmöglich ist. Die für den Durchgang der Luft bestimmten Kanäle liegen im Innern der Patrone. Die Chemikalmasse kann daher nicht durch reine Gewichtsbelastung nach einer Seite hin Wegsinken, und die neuen Patronen werden wesentlich besser als bisher ausgenutzt.During the use of the cartridges, the housing wall is formed in them adjacent chemical coat so much softened and due to adhesion to the sheet metal wall captured grains that the occurrence of short-circuit paths is impossible. The for Channels that determine the passage of air are located inside the cartridge. The chemical mass therefore cannot sink to one side simply by weight bearing, and the new cartridges are being used much better than before.

In der Zeichnung sind einige Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. -Die Abb. i bis 6 zeigen Querschnitte und Ansichten von oben von Faltensieben mit geradlinig, gleichachsig und strahlenförmig verlaufenden Falten.In the drawing are some exemplary embodiments of the subject matter of the invention shown. - Figs. I to 6 show cross-sections and views from above of folded screens with straight, equiaxed and radial folds.

Die Abb.7 stellt einen Längsschnitt durch eine mit den neuen Faltensieben beschickte Patrone dar.Figure 7 shows a longitudinal section through one with the new folding screens loaded cartridge.

Wie namentlich aus den Abb. 1, 3 und 5 ersichtlich, besitzen die zur Aufnahme der Chemikalmasse dienenden Faltensiebe b je einen ebenen Flansch a, der- die Bildung eines in Abb. 7 dargestellten Chemikalmantels e entlang der Gehäusewand ermöglicht. Die Luft kann daher die Luftreinigungspatrone nur durch die innerhalb der Chemikalsäulen d liegenden Kanäle c durchströmen.As can be seen by name from Figs. 1, 3 and 5, have the for Folded sieves b used to hold the chemical mass each have a flat flange a, which- the formation of a chemical jacket e shown in Fig. 7 along the housing wall enables. The air can therefore only pass through the inside of the air cleaning cartridge of the chemical columns d flow through channels c.
