Description

Filtergehäuse, insbesondere für Atmungsfilter Die Erfindung betrifft ein Gehäuse, das insbesondere für Atmungsfilter verwendet werden soll. Die bisher zum Aufbau der Gehäuse von Atmungsfiltern benutzten Metalle weisen naturgemäß glatte Oberflächen auf. Daher besteht die Gefahr, daß die zu reinigende Luft zum Teil an der glatten inneren Wand des Gehäuses vorbeistreicht und mit der Reinigungsmasse nicht in die nötige innige Berührung kommt, so daß ein vielleicht auch nur geringer Teil der die schädlichen Gase enthaltenden Luft ungereinigt dem Gerätträger zugeführt wird.Filter housings, particularly for breathing filters The invention relates to a housing that is to be used in particular for breathing filters. The so far Metals used to construct the housing of breathing filters are naturally smooth Surfaces on. Therefore, there is a risk that the air to be cleaned is partly on brushed past the smooth inner wall of the housing and with the cleaning compound does not come into the necessary intimate contact, so that perhaps only a minor one Part of the air containing the harmful gases is fed to the device carrier uncleaned will.

Um dies zu vermeiden, hat man die glatte Wandung der Atmungsfilter rauh gemacht, indem man sie mit einem Klebstoff versah und auf diesen gepulverte und gekörnte Chemikalien auftrug oder eine Mischung aus Chemikalien und Klebstoff auf die Wandungen aufbrachte. Dieses Verfahren ist aber umständlich, zeitraubend und kostspielig.To avoid this, you have the smooth wall of the breathing filter made rough by providing them with an adhesive and powdering them on top of them and applied granular chemicals or a mixture of chemicals and glue applied to the walls. However, this procedure is cumbersome and time-consuming and expensive.

Dieser übelstand wird nun gemäß der Erfindung dadurch behoben, daß man an Stelle von Eisen oder anderen Metallen zum Aufbau des Gehäuses von Atmungsfiltern gasdicht gemachte Pappengußmasse oder gasdicht gemachtes Papiermach6 verwendet. Diese Stoffe besitzen von ihrer Herstellung her bereits .eine rauhe Oberfläche, die sich bei Bedarf noch leicht weiter aufrauhen läßt, so daß die Luft nicht so leicht an den Wandungen des Gehäuses entlang durchtreten kann.This drawback is now remedied according to the invention in that instead of iron or other metals to build the housing of breathing filters gastight made paperboard molding compound or gastight papermach6 is used. These fabrics already have a rough surface due to their production. which can be easily roughened further if necessary, so that the air does not look like this can easily pass along the walls of the housing.

Deraitige Gehäuse lassen sich schnell und billig, z. B. durch Gießen, herstellen und sind außerdem widerstandsfähig gegen die zerstörenden Einflüsse der Witterung und der Chemikalien. Auch kann keine Korrosionsgefahr eintreten.Deraitige housing can be quickly and cheaply, z. B. by casting, and are also resistant to the destructive effects of Weather and chemicals. There can also be no risk of corrosion.
