Abstract

It is known to protect operators' cabins from external influences by dust filters and/or chemisorption filters. In order to create a filter for this purpose in a compact construction and having filter packages of different chemisorption compound coatings, according to the invention it is proposed that the filter has a wedge shape, a fan (2) being arranged in the interior (3) of the wedge shape. The filter packages have a three-layer chemisorption arrangement, the first layer (4) being preferably composed of soda lime and the second layer (5) being composed of expanded calcium aluminium silicate which is impregnated with H2S-oxidisable substances, and the activated charcoal coating (6) being arranged as third layer. <IMAGE>

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Filter für Kraftfahrzeugkabinen, vorzugsweise für die Landwirtschaftsfahrzeuge".Filters for motor vehicle cabins, preferably for agricultural vehicles ".

Es ist bekannt, die Fahrzeugkabinen durch Staubfilter oder aber durch Chemisorptionsfilter gegen äußere Einflüsse zu schützen, so daß der Fahrer und die Insassen des Fahrzeuges nicht belästigt werden.It is known that the vehicle cabs through or through dust filters Chemisorption filters to protect against external influences, so that the driver and the Vehicle occupants are not bothered.

Es ist bekannt, Filter für Fahrzeuge aus Gewebefiltern und Akohle herzustellen.It is known filters for vehicles made of fabric filters and carbon to manufacture.

Erfindungsgemäß wird vorgeschlagen, Filter zu verwenden, die eine kleinbauende Form aufweisen und mit Filterpaketen verschiedener Chemisorptionsmassen-Beschichtungen zusammengesetzt auszubilden.According to the invention it is proposed to use filters that have a have a compact form and with filter packs of different chemisorptive coatings to train assembled.

In der beiliegenden Zeichnung ist eine erfindungsgemäße Kompaktbau-Filtertechnik dargestellt: mit (1) - der Ansaugstutzen; mit (2) - das Gebläse - das erfindungsgemäß in der keilförmigen Anordnung des Freiraums Filter (3) angesetzt ist; mit (4),(5),(6) - die Chemisorptionsmassen, die erfindungsgemäß bestehen 1. aus Natronkalk und/oder Natroncarbonat zur Abscheidung von NO2; 2. aus geblähtem Caleiumaluminium-Silikat in getränkter Ausführung zur Oxidation von Geruchsstoffen, wie H2S mit Eisen-II-Lösung; mit (6) - eine Akohlefilterschicht; mit (7) - das Filtergehäuse; mit (8) - der Ausbiasstutzen.In the accompanying drawing is a compact filter technology according to the invention shown: with (1) - the intake manifold; with (2) - the fan - according to the invention in the wedge-shaped arrangement of the free space filter (3) is attached; with (4), (5), (6) - the chemisorption masses, which according to the invention consist of 1. soda lime and / or soda carbonate for the separation of NO2; 2. Made of expanded calcium aluminum silicate in an impregnated version for the oxidation of odorous substances, such as H2S with iron (II) solution; with (6) - an carbon filter layer; with (7) - the filter housing; with (8) - the blow-out nozzle.

Durch diese erfindungsgemäße Ausführung werden die schweren, geruchsbelästigenden Stoffe, insbesondere bei Landwirtschaftsfahrzeugen, z.B. beim Verteilen von Gülle, beseitigt, so daß der Fahrer von den belastenden Stoffen befreit bleibt, und auch der Vielfahrer hat einen Filter zur Verfügung, der wunschgerecht kleinbauend im Kofferraum oder unter den Sitzflächen des Fahrzeuges angebracht werden kann, wobei durch die keilförmige Anordnung der Filtermassen insbesondere neben der Schadstoffbeseitigung auch die Schallquelle des Ventilators und Wasserstoffverbindungen, insbesondere Schwefelwasserstoff-und Kohlenwasserstoff-Verbindungen, sowie N°2-Verbindungen, die den Menschen gefährden, gedämmt werden, wobei insbesondere die NO##Verbindungen, die auf empfindliche Menschen im Atembereich (Bronchien) sehr stark einwirken, und Geruchs- und Reizstoffe sowie auch krebserregende Stoffe wie Kohlenwasserstoffe, Benzpyrene usw. in der Kombination oder kumulierend mit anorganischen Stoffen wie SO2, N02 und Staub, durch die Filteranordnung von den Menschen ferngehalten werden.With this embodiment according to the invention, the heavy, odorous Substances, especially in agricultural vehicles, e.g. when distributing liquid manure, eliminated, so that the driver remains free from the polluting substances, and also the frequent traveler has a filter available that can be built in as small as required in the Trunk or under the seats of the vehicle can be attached, with due to the wedge-shaped arrangement of the filter media, especially in addition to removing pollutants also the sound source of the fan and hydrogen compounds, in particular Hydrogen sulfide and hydrocarbon compounds, as well as N ° 2 compounds, which endanger humans, are insulated, whereby in particular the NO ## connections, which have a very strong effect on sensitive people in the breathing area (bronchi), and Odor and irritants as well as carcinogenic substances such as hydrocarbons, Benzpyrene etc. in combination or cumulative with inorganic substances such as SO2, N02 and dust are kept away from people by the filter arrangement.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, ein Luft-Filter-System für Arbeitskabinen, vorzugsweise Autokabinen, so herzustellen, daß der Chemisorptionsfilter keilförmig im Filtergehäuse angeordnet und mit einem in der Keilanordnung angesetzten blasenden und/oder saugenden Ventilator ausgerüstet ist und die Chemisorptionsmassen in der beschriebenen Anordnung hintereinander Anwendung finden oder aber auch als Gemischtmasse in einer Paketform ausgebildet sein können Patent - rüche Of course, the invention is not limited to the embodiments shown and described in detail above, but numerous modifications are possible without, however, deviating from the basic idea of producing an air filter system for work cabins, preferably car cabins, so that the chemisorption filter is wedge-shaped in the The filter housing is arranged and equipped with a blowing and / or sucking fan set in the wedge arrangement and the chemisorption masses are used one after the other in the arrangement described or can also be designed as a mixed mass in a package form Patent scents
