Abstract

A filter for the absorption of pollutants before they can enter the passenger compartment of motor vehicles or other cabs, uses as the filter medium a non-inflammable granular material of high porosity, such as expanded perlite or clay. This material is packed in a bag with filter capacity, made of non-inflammable fibres (ceramic). If moisture or other noxious substances are to be absorbed, another bag filled with perlite, coated with soda lime or activated carbon, can be arranged in series. This type of filter can be readily adapted to any size of motor car from the smallest to the biggest. No prepns. are required to make the filter insert suitable for individual requirements.

Description

Beschreibung und Erläuterung zur Patent- und llilfs-Description and explanation of the patent and

gebrauchsmusteranmeldung 'Filter zur Ansaugluftreinigung für Autokabinen' Das Einbringen der Filtermasse für die verschiedensten Ansaugkanäle bei den Autotypen ist sehr schwierig und bedeutet eine Vielzahl von Formgebungen zur guten Abdichtung der Frischluftansaugkanäle und somit eine sehr kostenaufwendige Vorleistung, um die Filter individuell einsatzfähig zu gestalten.Utility model registration 'Filters for air intake cleaning for car cabins' The introduction of the filter material for the various intake ducts in the types of cars is very difficult and means a variety of shapes for a good seal the fresh air intake ducts and thus a very costly advance payment in order to to make the filters individually usable.

Weiterhin müssen die Filtermassen vor zu starker Wasseraufnahme geschützt werden.Furthermore, the filter media must be protected from excessive water absorption will.

Auch hierzu sind Abdeckvorrichtungen individueller Bauweise erforderlich.Covering devices of an individual design are also required for this purpose.

Um die Nachteile der individuellen Formgebung zu beseitigen und trotzdem für jedes Fahrzeug in einfachster Weise den Einbau der absorbierenden Filtermassen zu ermöglichen, wird erfindungsgemäß folgende Lösung vorgeschlagen.To eliminate the disadvantages of individual design and still the installation of the absorbent filter media in the simplest way for every vehicle to enable the following solution is proposed according to the invention.

Die Absorptionsmassen bestehen aus porösen körnigen Massen.The absorption masses consist of porous granular masses.

Diese körnigen Massen werden erfindungsgemäß in verformbare, aus Filterstoff bestehende, kissenförmige Elemente eingepackt.According to the invention, these granular masses are made of deformable filter material existing, pillow-shaped elements packed.

Diese kissenförmigen Elemente, die z.B. aus einer dünnen, filternden, strumpfartigen Haut bestehen, können z.B. für einen kleinen Wagentyp die Innenmaße des Abdichtungselements besitzen. Bei der Verwendung für größere Wagen kann das Bauteil - Filterkissen -,nach Bedarf geformt,zu mehreren hintereinander, nebeneinander oder halb überlappend miteinander verbundenen Teilen, abdichtend als Filterbewehrung benutzt werden. Zur Wasserabweisung für das eigentliche Chemieabsorptionspaket wird erfindungsgemäß ein weiteres Filterkissenpaket benutzt, das ebenso luftdurchlässig ist und einen geringen Widerstand aufweist, andererseits jedoch stark wasseraufnahmefähig ist und erfindungsgemäß aus offenporigen, geschäumten Stoffen besteht, z.B. geblähter Perlite.These cushion-shaped elements, which e.g. consist of a thin, filtering, stocking-like skin, e.g. the inside dimensions for a small type of car own the sealing element. When used for larger cars, this can Component - filter pad - shaped as required, several in a row, next to each other or parts connected to one another in a semi-overlapping manner, sealing as filter reinforcement to be used. Is used to repel water for the actual chemical absorption package According to the invention, another filter pad pack is used, which is also air-permeable and has a low resistance, but on the other hand it is highly water-absorbent and according to the invention consists of open-pored, foamed materials, e.g. expanded Perlite.

Erfindungsgemäß ist auch diese wasseraufnehmende Anordnung ebenfalls als Filterpaketkissen ausgebildet mit einer strumpfartigen Hülle und läßt sich aus diesem Grunde ebenso wie das Chemiesorptionspaket nebeneinander, hintereinander und/oder überlappend verlegen.This water-absorbing arrangement is also according to the invention designed as a filter pack cushion with a stocking-like cover and can be removed for this reason as well as the chemical sorption package side by side, one behind the other and / or laid in an overlapping manner.

Erfindungsgemäß sind die porösen Massen aus nicht brennbaren Massen hergestellt wie z.B. geblähte Perlite oder Blähton.According to the invention, the porous masses are made from non-combustible masses manufactured such as expanded perlite or expanded clay.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen ausgebildeten Formen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Absorptionsfilter für vorzugsweise Autokabinen und Arbeitskabinen so auszubilden, daß das absorbierende Material aus porösen körnigen Massen besteht, die durch eine verformbare Umhüllung kissenförmig verpackt sind und entsprechend jeder Ansaugform einer Auto- oder Arbeitskabine von Hand aus verformbar angepaßt werden können und mit benachbarten Elementen eine abdichtende tberlappung ermöglichen, und daß diese Absorptionsfilter mit gleichen paket artigen Kissen gegen Wasseraufnahme bedarfsgerecht abgedeckt werden können und die filternden Massen aus nicht brennbaren porösen Stoffen, vorzugsweise geblähter Perlite, bestehen und die Umhüllung vorzugsweise ebenfalls nicht brennbar, z.B. aus keramischen Fasern, hergestellt ist.Of course, the invention is not limited to the above in detail formed forms, but numerous modifications are possible, However, without departing from the basic idea, an absorption filter for preferably To train car cabins and work cabins so that the absorbent material consists of porous granular masses, which are cushion-shaped by a deformable envelope are packed and according to every suction form of a car or work cabin of Can be adjusted by hand from deformable and sealed with adjacent elements Allow overlapping, and that these absorption filters with the same packet-like Cushions against water absorption can be covered as needed and the filtering There are masses of non-flammable porous materials, preferably expanded perlite and the covering is preferably also non-combustible, e.g. made of ceramic fibers, is made.

Die Füllstoffe der Filterkissen bestehen für das obere verformbare Kissen aus geblähter Perlite, die mit Natron-Kalk gemischt ist. Anstelle von Perlite kann auch geblähter Ton Anwendung finden. Hierdurch werden H20 + C02 + organische + anorganische Stoffe absorbiert (z.B. Nu ).The fillers of the filter pads are made for the top deformable Pillow made of expanded perlite mixed with soda-lime. Instead of perlite can also inflated tone find application. This will make H20 + C02 + organic + inorganic substances absorbed (e.g. Nu).

Das darunter liegende Kissen mit der weiteren Füllung besteht ebenfalls aus geblähter Perlite, die mit Natronlauge getränkt und mit metallischem Kupferstaub ummantelt ist zur Chemiesorption von vorzugsweise CO und organischen und anorganischen Schadstoffen.The pillow underneath with the additional filling also exists made of expanded perlite soaked with caustic soda and with metallic copper dust is encased for chemisorption of preferably CO and organic and inorganic Pollutants.

Die darunter liegende Absorptionsschicht besteht aus geblähter Perlite, mit Natronkalk und A-Kohle vermischt, zur Chemiesorption von Kohlenwasserstoffen (Benzpyren) und anderen organischen und anorganischen Schadstoffen (geruchsbindende Feinreinigungsschicht).The absorption layer underneath consists of expanded perlite, mixed with soda lime and activated charcoal for chemical sorption of hydrocarbons (Benzpyrene) and other organic and inorganic pollutants (odor-binding Fine cleaning layer).
