Abstract

Producing a protective respiration filter, involves mixing of adsorptive, absorptive, chemisorptive or catalytic materials, in particular, activated carbon, with one or more meltable polymers and heating of this mixture under pressure. The heating process takes place in a connector element of an individual respiration filter or a fan filter, or in a connector element of adapters of such filters, and results in an airtight joint being formed between the pressed filter material and its container. An Independent claim is also included for an apparatus for implementation of the proposed method.

Description

Die Erfindung betrifft einen Atemfilter aus matrixgebundenem Filtermaterial, insbesondere Aktivkohle.The invention relates to a breathing filter made of matrix-bound filter material, in particular activated carbon.

Derartige Filter sind bekannt. So wird in der US-PS 5,078,132 die Herstellung eines Atemfilters beschrieben, bei dem das Filtergranulat durch Polymere gebunden wird. Dies erfolgt beim Pressen zylinderförmiger und schalenförmiger Formkörper. Die Formkörper werden dann in eine Maske als Filter eingebaut und sind starr mit dieser verbunden.Such filters are known. Thus, US Pat. No. 5,078,132 describes the production of a respiratory filter in which the filter granules are bound by polymers. This is done when pressing cylindrical and cup-shaped moldings. The moldings are then incorporated into a mask as a filter and are rigidly connected thereto.

Aus der DE 197 14 350 A1 ist ein polymergebundenes körniges ad-, ab-, chemisorptiv oder katalytisch wirkendes Material und ein Verfahren zur Herstellung von Formkörpern daraus bekannt. Dabei wird ein schmelzbares Polyethylen in einem geeigneten Mischgefäß mit einem Oligokondensat intensiv benetzt, das feinkörnige, ad-, ab-, chemisorptiv oder katalytisch wirkende Material zugegeben, die Mischung intensiv gemischt, die Mischung über ein geeignetes Transportsystem einer Verarbeitungsmaschine zugeführt und die Mischung bei Temperaturen von 90° bis 180° C, vorzugsweise 100° bis 140° C, und Drücken von 0,0125 bis 0,25 bar/cm2, vorzugsweise 0,0225 bis 0,0625 bar/cm2, in einer Form zu einem Formkörper verpresst, der Formkörper in der Form gekühlt und anschließend entformt.DE 197 14 350 A1 discloses a polymer-bound granular adsorbent, ab, chemisorptive or catalytically active material and a process for the production of moldings therefrom. In this case, a meltable polyethylene is thoroughly wetted in a suitable mixing vessel with an oligocondensate, the fine-grained, ad-, ab-, chemisorptive or catalytically active material added, the mixture mixed intensively, the mixture fed through a suitable transport system of a processing machine and the mixture at temperatures from 90 ° to 180 ° C, preferably 100 ° to 140 ° C, and pressures of 0.0125 to 0.25 bar / cm 2 , preferably 0.0225 to 0.0625 bar / cm 2 , in a mold to a shaped body pressed, the molded body cooled in the mold and then removed from the mold.

Die Verwendung derartiger Formkörper als Filter für Atemschutzmasken weist insofern einen Nachteil auf, als dass das gasdichte Einpassen der Formkörper in Einsätze von Atemschutzmasken oder Hauben technologisch aufwendig ist. Hinzu kommt, dass die Formkörper gerade im Randbereich eine eingeschränkte mechanische Stabilität aufweisen.The use of such moldings as a filter for respiratory masks has a disadvantage in that the gas-tight fitting of the moldings in operations of respirators or hoods is technologically complex. In addition, the moldings have a limited mechanical stability, especially in the edge region.

Aufgabe der Erfindung ist es, matrixgebundenes Filtermaterial, wie matrixgebundene Aktivkohle, kostengünstig und zuverlässig für die Nutzung in Atemfiltergeräten, insbesondere Atemmasken und -hauben, aufzubereiten. Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Verfahrensanspruchs 1 und des Vorrichtungsanspruches 2, vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The object of the invention is to process matrix-bound filter material, such as matrix-bonded activated carbon, inexpensively and reliably for use in respirator devices, in particular respiratory masks and hoods. This object is achieved with the characterizing features of method claim 1 and the device claim 2, advantageous embodiments are the subject of the dependent claims.

Das erfindungsgemäße Verfahren zur Herstellung eines Atemschutzfilters, bei dem-ein körniges ad-, ab-, chemisorptiv oder katalytisch wirkendes Material, insbesondere Aktivkohle, mit einem schmelzbaren Polymere vermischt und die Mischung unter Druck erhitzt und dabei zu einem Formkörper verpresst wird, sieht vor, dass die Mischung in einem Anschlussteil für einen Atemanschluss oder für ein Gebläsefiltergerät oder in einem Anschlussteil für einen Adapter für einen Atemanschluss oder für ein Gebläsefiltergerät unter Druck erhitzt und dabei mit diesem form- und/oder kraftschlüssig verpresst wird und die Verbindung zwischen Anschlussteil und verpresster Mischung gasdicht ist. Entsprechend besteht bei der erfindungsgemäßen Form mit verpresster Mischung die Form aus einem Anschlussteil für einen Atemanschluss, ein Gebläsefiltergerät oder einen Adapter für diese.The inventive method for producing a respiratory protection filter, in which a granular ad, ab, chemisorptive or catalytically active material, in particular activated carbon, mixed with a meltable polymer and the mixture is heated under pressure and thereby pressed into a shaped body provides, provides that the mixture is heated in a connection part for a breathing connection or for a blower filter device or in a connection part for an adapter for a breathing connection or for a blower filter device under pressure while being pressed with this positive and / or non-positive and the connection between the connector and compressed mixture is gas-tight. Accordingly, in the mold according to the invention with compressed mixture, the mold consists of a connection part for a breathing connection, a blower filter device or an adapter for this.

Das Anschlussteil ist vorzugsweise ringförmig ausgebildet und weist an der Innenfläche eine vollständig oder teilweise umlaufende Nut oder Feder auf, in die der verpresste Formkörper eingreift oder bei einer Feder diese teilweise umschließt. Möglich sind auch ovale, rechteckige oder andere Geometrien.The connecting part is preferably annular and has on the inner surface of a completely or partially circumferential groove or spring into which engages the pressed molding body or this partially encloses a spring. Also possible are oval, rectangular or other geometries.

Am äußeren Umfang weist das das Anschlussteil Verbindungselemente für einen gasdichten lösbaren Anschluss an einen Atemanschluss oder an ein Gebläsefiltergerät oder zum gasdichten Anschluss an einen Adapter zum Anschluss an einen Atemanschluss oder an ein Gebläsefiltergerät auf. Dabei kann auch der Anschluss für einen Adapter lösbar ausgeführt sein. Das Anschlussteil besteht bevorzugt aus einem Polymer mit einem höheren Schmelzpunkt als das Polymer des Formkörpers, oder aus Pappe oder aus Metall.On the outer circumference, the connection part has connecting elements for a gastight detachable connection to a breathing connection or to a blower filter device or for a gastight connection to an adapter for connection to a breathing connection or to a blower filter device. In this case, the connection for an adapter can be made detachable. The connecting part is preferably made of a polymer having a higher melting point than the polymer of the shaped body, or of cardboard or of metal.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Die FIG. zeigt, dass die Form für den Atemschutzfilter aus einem Anschlussteil 1 besteht, in das die Mischung aus einem körnigen ad-, ab-, chemisorptiv oder katalytisch wirkenden Material, insbesondere Aktivkohle, und einem schmelzbaren Polymer unter Druck erhitzt und dabei zu einem Formkörper 2 verpresst wurde. Zwischen dem Anschlussteil 1 und dem verpressten Formkörper 2 besteht eine form- und/oder kraftschlüssige und gasdichte Verbindung.An embodiment of the invention is shown in the drawing. The FIG. shows that the shape of the respiratory filter consists of a connection part 1, in which the mixture of a granular ad, ab, chemisorptive or catalytically active material, in particular activated carbon, and a fusible polymer heated under pressure and thereby pressed into a shaped body 2 has been. There is a positive and / or non-positive and gas-tight connection between the connection part 1 and the compressed molded body 2.

Das Anschlussteil 1, hier ringförmig ausgebildet, weist an der Innenfläche eine umlaufende Feder 5 auf, die vom Formkörper 2 teilweise umschlossen wird. Das schafft eine hohe Sabilität der Verbindung Anschlussteil 1 / Formkörper 2.The connecting part 1, in this case annular, has on the inner surface a circumferential spring 5, which is partially enclosed by the molded body 2. This creates a high level of stability of the connection connection part 1 / molded body 2.

Das Anschlussteil 1 besitzt am äußeren Umfang Verbindungselemente 3 für einen gasdichten lösbaren Anschluss an einen Adapter 4 zum Anschluss an einen Atemanschluss oder ein Gebläsefiltergerät. In der Darstellung ist diese als Rastverbindung ausgebildet. Möglich ist auch eine andere herkömmliche Verbindung, wie Gewinde, Bajonettverschluss etc.The connection part 1 has on the outer circumference connecting elements 3 for a gas-tight releasable connection to an adapter 4 for connection to a breathing connection or a blower filter device. In the illustration, this is designed as a latching connection. Also possible is another conventional connection, such as thread, bayonet lock, etc.

Anstelle des Anschlusses an einen Adapter 4 ist auch der direkte lösbare gasdichte Anschluss an einen Atemanschluss oder an ein Gebläsefiltergerät vorgesehen.Instead of the connection to an adapter 4, the direct detachable gas-tight connection to a respiratory connection or to a blower filter device is also provided.

Das Anschlussteil 1 erfüllt somit drei Funktionen: Es ist Halterung für die matrixgebundene Aktivkohle, es dient der Luftführung der zu filternden Luft durch die matrixgebundene Aktivkohle und gewährleistet einen lösbaren gasdichten Anschluss an einen Atemanschluss oder an ein Gebläsefiltergerät oder einen Adapter 4. Die Lösbarkeit gewährleistet dabei die sichere und einfache Austauschbarkeit der Atemfilter.The connection part 1 thus fulfills three functions: it is a holder for the matrix-bonded activated carbon, it serves to guide the air to be filtered through the matrix-bonded activated carbon and ensures a detachable gas-tight connection to a breathing connection or to a blower filter device or an adapter 4. The solubility ensures this the safe and easy replacement of the respiratory filter.
