Die Erfindung bezieht sich auf eine Filtereinrichtung, insbesondere zur Filtration von Gasen oder Flüssigkeiten in Fahrzeugen, mit einem in einem Filtergehäuse angeordneten Filterelement, das von dem zu filtrierenden Fluid zu durchströmen ist.The The invention relates to a filter device, in particular for the filtration of gases or liquids in vehicles, with a filter element arranged in a filter housing, which is to flow from the fluid to be filtered.
Stand der TechnikState of the art
In
der
Zur Verbesserung der Filtrationswirkung ist das Filterelement zweilagig aufgebaut und umfasst eine radial umgreifende, äußere Schicht aus Filtermaterial mit geringerer Dichte und eine radial innenliegende Schicht aus Filtermaterial mit höherer Dichte. Hierdurch entsteht in radialer Durchströmrichtung ein sandwichartiger Filteraufbau mit sprunghaft zunehmender Dichte, was zu dem Effekt führt, dass an der radialen Außenseite größere Partikel und im Übergang zwischen äußerer zu innerer Filterlage Fein- und Feinstpartikel abgeschieden werden.to Improvement of the filtration effect, the filter element is two-ply constructed and includes a radially encircling, outer layer of filter material with a lower density and a radially inner layer Filter material with higher Density. This creates a sandwich-like in the radial flow direction Filter construction with skyrocketing density, resulting in the effect leads, that on the radial outside larger particles and in transition between outer to inner filter layer fine and very fine particles are deposited.
Das Filterelement muss aus zwei Einzelfiltern zusammengesetzt werden, wobei einerseits auf ein flächiges Aneinanderliegen der beiden Filter elemente aneinander zu achten ist, um Fehlluftströme in Umfangsrichtung zwischen den Lagen zu vermeiden, und andererseits die Verbindung zwischen den Filterlagen, für die beispielsweise Klebstoff verwendet wird, nicht zu einem erhöhten Filtrationsdruck und einer verminderten Filtrationsleistung führen darf.The Filter element must be composed of two individual filters, on the one hand on a flat Adjacent the two filter elements to each other is to miss airflows in the circumferential direction between the layers to avoid, and on the other the connection between the filter layers, for example, adhesive is used, not to an increased filtration pressure and a may result in reduced filtration performance.

Offenbarung der ErfindungDisclosure of the invention
Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, mit einfachen Maßnahmen eine Filtereinrichtung zur Filtration von Fluiden zu schaffen, deren Filterelement eine mit geringem Aufwand zu variierende bzw. einzustellende Dichte aufweist.From Based on this prior art, the invention has the object underlying, with simple measures to provide a filter device for the filtration of fluids whose Filter element with a little effort to be varied or set Has density.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.These Task is according to the invention with the Characteristics of claim 1 solved. The dependent claims give expedient further education at.
Die erfindungsgemäße Filtereinrichtung, die beispielsweise zur Filtration von Luft in Kraftfahrzeugen, insbesondere Verbrennungsluft oder die dem Fahrzeuginnenraum zuzuführende Luft eingesetzt wird, darüber hinaus aber auch zur Flüssigkeitsfilterung verwendet werden kann, beispielsweise zur Ölfilterung oder zur Kraftstofffilterung, weist ein in einem Filtergehäuse angeordnetes, als Schaumstoffelement ausgeführtes Filterelement auf, das in das Filtergehäuse eingepresst ist. Dadurch weist das Filterelement – bezogen auf den unkomprimierten Ausgangszustand – zumindest einen Abschnitt mit erhöhter Dichte auf, wodurch sich auch die Filtrationseigenschaften des Filterelementes ändern. Dieser Effekt kann in gezielter Weise zur Beeinflussung der Filtrationseigenschaften ausgenutzt werden. Hierbei wird das Schaumstofffilterelement zweckmäßig in der Weise in das Filtergehäuse eingeklemmt, dass sich in Durchströmrichtung eine Dichteänderung ergibt.The filter device according to the invention, for example, for the filtration of air in motor vehicles, in particular Combustion air or the air to be supplied to the vehicle interior is used, about it but also for liquid filtration can be used, for example for oil filtration or for fuel filtration, has a in a filter housing arranged, designed as a foam element filter element, the in the filter housing is pressed. This shows the filter element - related to the uncompressed initial state - at least a section with elevated Density, which also change the filtration properties of the filter element. This effect can in a targeted way to influence the filtration properties be exploited. Here, the foam filter element is appropriate in the way in the filter housing clamped, that in the flow direction, a density change results.
Diese Dichteänderung kann gemäß einer ersten vorteilhaften Ausführung das gesamte Filterelement erfassen, so dass innerhalb des als Schaumstoffblock ausgeführten Filterelementes keine Dichtegradienten vorliegen, sondern eine einheitliche, erhöhte Dichte vorliegt. Gemäß einer zweiten vorteilhaften Ausführung kann es aber auch zweckmäßig sein, einen Dichtegradienten gezielt herbeizuführen, so dass verschiedene Abschnitte innerhalb des Schaumstoffblockes einen unterschiedlichen Dichtegrad aufweisen, wobei die Dichteänderung sowohl sprunghaft als auch kontinuierlich erfolgen kann.These density change can according to a first advantageous embodiment capture the entire filter element, so that within the foam block executed Filter element there are no density gradients, but a uniform, increased Density is present. According to one second advantageous embodiment but it may also be appropriate to bring about a density gradient, so that different Sections within the foam block a different Density, wherein the density change both leaps and can also be done continuously.
Die Dichteänderung wird in erster Linie durch das Einpressen in den Filteraufnahmeraum im Filtergehäuse erreicht. Hierdurch erfährt das Filterelement außerdem eine Klemmkraft, die bereits ausreichend groß sein kann, um das Filterelement sicher in Einbaulage zu halten. Es können aber zusätzliche Befestigungsmaßnahmen zur Halterung des Filterele mentes im Filtergehäuse vorgesehen sein, beispielsweise kann das Filterelement durch Schweißen, insbesondere Vibrationsschweißen, durch Einklipsen oder durch Kleben in der Einbaulage fixiert sein. Je nach Kompressionsgrad wird eine unterschiedlich hohe Dichteänderung im Schaumstoffblock erreicht. Es kann hierbei zweckmäßig sein, eine Verdichtung auf das mehrfache des Ausgangswertes durchzuführen, beispielsweise auf das Fünffache, was einer entsprechenden Dichteerhöhung auf den fünffachen Wert entspricht. Beträgt die Dichte beispielsweise im unkomprimierten Ausgangszustand 5 %, so steigt sie bei einer Verdichtung auf das fünffache auf 25 % an.The density change is primarily by the press-fitting into the filter receiving space in the filter housing reached. Learns through this the filter element as well a clamping force, which may already be sufficiently large, around the filter element safe to keep in installation position. But it can be extra fastening measures be provided for holding the Filterele Mentes in the filter housing, for example can the filter element by welding, in particular vibration welding, by Clipping in or fixed by gluing in the installation position. Depending on Compression degree becomes a different density change reached in the foam block. It may be appropriate to perform a compression to the multiple of the initial value, for example fivefold, what a corresponding increase in density to five times the value equivalent. is the density for example in the uncompressed initial state 5%, for example, it increases fivefold to 25% when compressed.
Für den Fall einer gleichmäßigen Dichteerhöhung reicht es grundsätzlich aus, das Filterelement in seiner geometrischen Dimension passend zum Filteraufnahmeraum zu fertigen und nach dem Einsetzen in den Filteraufnahmeraum mithilfe eines Deckels oder dergleichen gleichmäßig zusammenzudrücken.In the case of a uniform density increase, it is basically sufficient to manufacture the filter element in its geometrical dimension matching the filter receiving space and after the Insert into the filter receiving space by means of a lid or the like evenly compress.
Je nach Art des verwendeten Filterschaumes weist dieser plastische oder elastische Eigenschaften auf. In beiden Fällen wird bei einer Verdichtung des Filterschaumes eine Klemmkraft an allen unmittelbar begrenzenden Wandungen erzeugt. Eine Ausführung als elastischer Schaumstoffblock weist den Vorteil auf, dass die Klemmkraft als Materialeigenschaft des elastischen Filterschaumstoffes erzeugt wird.ever according to the type of filter foam used, this plastic or elastic properties. In both cases, in a compression the filter foam a clamping force at all immediately limiting Created walls. An execution As elastic foam block has the advantage that the Clamping force as the material property of the elastic filter foam is produced.
Für den Fall einer ungleichmäßigen Dichteverteilung innerhalb des Schaumstoffblockes im eingesetzten Zustand, also bei einem Dichtegradienten im Filterelement, können die Filtereigenschaften in der gewünschten Weise beeinflusst werden. Erreicht wird diese unterschiedliche Dichteverteilung beispielsweise dadurch, dass das Filterelement zumindest in einer Dimension einen veränderlichen Querschnitt aufweist und zumindest abschnittsweise eine gegenüber dem Filteraufnahmeraum größere Geometrie besitzt. Zum Einsetzen des Filterelements in den Filteraufnahmeraum wird das Material des Filterelements komprimiert, wodurch die gewünschte Dichteänderung erzielt wird. Die Dichteänderung erfolgt aber aufgrund der abweichenden Geometrie zum Filteraufnahmeraum sowie der sich beim Einschieben ändernden Querschnittsgeometrie des Filterelementes nicht gleichmäßig, wodurch die Abschnitte unterschiedlicher Dichte erzeugt werden. Zweckmäßigerweise verläuft die Dichteänderung vollständig kontinuierlich innerhalb des Filterelementes.In the case an uneven density distribution within the foam block in the inserted state, ie at a density gradient in the filter element, the filter properties in the desired Be influenced. This different density distribution is achieved for example, characterized in that the filter element at least in one Dimension a variable Has cross-section and at least partially one with respect to the Filter receiving space larger geometry has. For inserting the filter element into the filter receiving space the material of the filter element is compressed, whereby the desired density change is achieved. The density change but due to the different geometry to the filter receiving space as well as changing during insertion Cross-sectional geometry of the filter element is not uniform, which the sections of different density are generated. Conveniently, extends the density change is completely continuous within the filter element.
Als bevorzugte Geometrien kann der Filteraufnahmeraum einen zylindrischen Querschnitt und das Filterelement im unbelasteten Zustand einen konischen Querschnitt aufweisen, wobei der Bereich mit dem größten Konusdurchmesser des Filterelementes den Innendurchmesser des zylindrischen Filteraufnahmeraumes übersteigt. Mit dem Einsetzen des Filterelementes in den Filteraufnahmeraum wird der Bereich mit dem größten Durchmesser radial zusammengepresst, wohingegen diejenigen Ab schnitte des Filterelementes, die einen kleineren oder gleichgroßen Durchmesser wie der zylindrische Filteraufnahmeraum aufweisen, keine radiale Kompression erfahren. Die Verdichtung erfolgt hierbei im Verhältnis der Quadrate des unbelasteten Außendurchmessers am konusförmigen Filterelement zum Innendurchmesser des Aufnahmeraumes.When preferred geometries, the filter receiving space can be a cylindrical Cross section and the filter element in the unloaded state a have conical cross-section, wherein the area with the largest cone diameter of the filter element exceeds the inner diameter of the cylindrical filter receiving space. With the insertion of the filter element in the filter receiving space becomes the area with the largest diameter radially compressed, whereas those from sections of the filter element, the smaller or the same diameter as the cylindrical one Have filter receiving space, experienced no radial compression. The compression takes place here in the ratio of the squares of the unloaded External diameter on the cone-shaped Filter element to the inner diameter of the receiving space.
Als Material für das Filterelement kommt jeder poröse und kompressible Schaum in Betracht, beispielsweise ein Schaum auf PUR-Basis oder ein Silikonschaum. Des Weiteren kann es zweckmäßig sein, das Filterelement mit einer Oberflächenbeschichtung zu versehen, um gewünschte zusätzliche Filtereigenschaften zu erzeugen.When Material for the filter element comes every porous and compressible foam for example, a foam based on PU or a silicone foam. Furthermore, it may be appropriate to provide the filter element with a surface coating, desired additional filter properties to create.
