Description

Die Erfindung betrifft eine mit Alkalisuperoxyd gefüllte Luftreinigungspatrone. Es ist bekannt, die Chemikalmasse in solchen Patronen auf sogenannten Furchensieben, das sind Siebe mit breiten und tiefen Chemikaltaschen und schmalen, furchenähnlichen Falten für den Durchgang der Atemluft, zu lagern. Bei diesen Patronen ist es üblich, zwischen zwei Furchensieben ein oder zwei Flachsiebe zu lagern, um gute Angriffsflächen für den durch die Patrone tretenden Luftstrom zu erhalten. Es hat sich jedoch gezeigt, daß derartige Ausgestaltungen der Luftverbindungswege zwischen den einzelnen Sieben verhältnismäßig hohe Widerstände ergeben, zumal die verwendeten Superoxydmassen bei der Reaktion mit der Ausatemluft quellen und die zur Verfügung stehenden Wege einengen.The invention relates to an air cleaning cartridge filled with alkali peroxide. It is known that the chemical mass in such cartridges on so-called furrow sieves, these are sieves with wide and deep chemical pockets and narrow, furrow-like ones Store folds for the passage of breathable air. It is common for these cartridges to store one or two flat sieves between two furrow sieves in order to have good contact surfaces for the airflow passing through the cartridge. However, it has been shown that such configurations of the air communication paths between the individual screens relatively high resistances result, especially since the superoxide compounds used in the reaction with the exhaled air swell and the available paths constrict.

Die Erfindung besteht nun darin, daß die Chemikalmasse in der Patrone abwechselnd auf Furchensieben und auf Wel.lsieben gelagert ist. Hierdurch wird einerseits ein größerer Zwischenraum zwischen je zwei Furchensiebreihen geschaffen, .der aber nicht einen unausgenutzten Raum bildet, sondern durch seine teilweise Chemikalfüllung für die Luftreinigung mit ausgenutzt wird.The invention now consists in that the chemical mass in the cartridge is stored alternately on furrow sieves and on shaft sieves. This is on the one hand a larger space was created between each two rows of furrow sieves, but the does not form an unused space, but rather through its partial chemical filling is also used for air purification.

Zweckmäßig wird dabei die Füllung der beiden Siebarten so getroffen, daß in den Chemikaltaschen der Furchensieb.e gröbere, in den Chemilealtascheri der Wellsiebe dagegen feinere Chemikalikörner eingelagert werden. Hierdurch ist es möglich, die beim Aussieben der Superoxydpräparate anfallenden kleineren Körner mit in der Patrone zu verwenden. die sonst in den großen und tiefen Chemikaltaschen der Furchensiebe einen zu hohen Atemwiderstand ergeben würden.The filling of the two sieves is expediently made in such a way that that in the chemical pockets the furrow sieve is coarser, in the chemical pockets the Corrugated sieves, on the other hand, contain finer chemical grains. This makes it possible the smaller grains obtained when sieving out the superoxide preparations are included in the Cartridge to use. those otherwise in the large and deep chemical pockets of the furrow sieves would result in too high a breathing resistance.

Eine besonders gute Ausnutzung der Chemikalmasse wird dann erreicht, wenn man .die Lufttaschen der Furchensiebe und Wellsiebe gegeneinander versetzt anordnet, so -daß die Luftwege der Furchensiebe von den Chemikaltaschen der Wellsiel)e überdeckt sind. Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsschnitt. Der Pfeil zeigt die Strömungsrichtung der Luft an. Die Chemikalmasse ist abwechselnd auf Furchensieben 3 und Wehsieben 4 gelagert. Die Furchensiebe 3 enthalten die grobkörnige Chemikalmasse, während die Wellsiebe 4 die kleineren Chemi.kalkörner enthalten. Die Wellsiebe sind so angeordnet, daß unterhalb der Lufttaschen der Furchensiebe mit Chemikalgefüllte Wellsiebtaschen liegen. Hierauf folgen weitere Paare von Furchensieben 3 und Wellsieben 4. Vor tder ersten und hinter der letzten Schicht sind Siebabdeckungen 5 und 6 angeordnet. Dem Luftaustritt ,ist noch ein besonderes Staubfilter 7 vorgeschaltet, das den Eintritt von Chemikalstaub in das Gerät verhindert.A particularly good utilization of the chemical mass is achieved if you move the air pockets of the furrow sieves and corrugated sieves against each other arranges so -that the airways of the furrow sieves from the chemical pockets of Wellsiel) e are covered. The drawing shows an embodiment of the subject matter of the invention in longitudinal section. The arrow shows the direction of air flow. The chemical mass is stored alternately on furrow sieves 3 and 4 weed sieves. The furrow sieves 3 contain the coarse-grained chemical mass, while the corrugated sieves 4 contain the smaller chemical lime grains contain. The corrugated sieves are arranged so that below the air pockets of the furrow sieves Corrugated sieve bags filled with chemicals lie. This is followed by further pairs of furrow sieves 3 and corrugated sieves 4. There are sieve covers in front of the first and behind the last layer 5 and 6 arranged. A special dust filter 7 is connected upstream of the air outlet, that prevents chemical dust from entering the device.

Um die Patrone schnell und leicht zum Anspringen zu bringen, empfiehlt es sich, an der Lufteintrittsseite der Patrone den Siebschichten eine Vollpackung aus hochporösen Superoxydpräparaten vorzuschalten.To get the cartridge to pop up quickly and easily, recommends it is, on the air inlet side of the cartridge, the sieve layers a full pack upstream from highly porous superoxide preparations.
