Description
Die vorliegende Erfindung bezieht sich auf einen Filter zum Einsetzen in einen Einfüllstutzen eines Behälters, vorzugsweise Tanks für Kraftstoff, Harnstofflösung oder andere Flüssigkeiten, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a filter for insertion into a filler neck of a container, preferably tanks for fuel, urea solution or other liquids, according to the preamble of
Bei Befüllsystemen mit optionaler Vorfiltrierung ist im Tankstutzen ein Vorfilter der eingangs genannten Art eingebaut, bei dem das am Auslaufende angeordnete Filtersieb senkrecht zur Strömungsrichtung der Flüssigkeit angeordnet ist. Dieses flache bodenseitige Filtersieb führt mit ihrer offenen Filterfläche zu einer nicht ausreichenden Durchströmung im Hinblick auf Volumen pro Zeiteinheit und außerdem zu Rückstaus aufgrund starker Turbulenzen vor dem Filtersieb. Dies kann beim Einfüllen mittels Zapfpistolen zu deren Abschalten während des Einfüllvorganges, was dadurch zu vermeiden ist, dass die Filterlänge und der Filterdurchmesser relativ groß gewählt werden. Dies wiederum wirkt sich nachteilig auf die Baugröße des Einfüllstutzens aus.In filling systems with optional pre-filtration, a prefilter of the type mentioned above is installed in the filler neck, in which the filter screen arranged at the outlet end is arranged perpendicular to the flow direction of the liquid. This flat bottom filter screen leads with its open filter surface to an insufficient flow in terms of volume per unit time and also to backflow due to strong turbulence in front of the filter. This can be done when filling by means of fuel nozzles to their shutdown during the filling process, which is to avoid the fact that the filter length and the filter diameter are chosen to be relatively large. This in turn has a detrimental effect on the size of the filler neck.
Aufgabe der vorliegenden Erfindung ist es, ein Filter zum Einsetzen in einen Einfüllstutzen eines Behälters der eingangs genannten Art zu schaffen, der an geringere Baugrößen von Einfüllstutzen, wie beispielsweise solcher von Harnstofftanks angepasst werden kann und der dennoch eine optimale Durchströmung (Volumen pro Zeiteinheit) aufweist, ohne dass die Gefahr eines rückstaubedingten Abschaltens einer Zapfpistole gegeben ist.Object of the present invention is to provide a filter for insertion into a filler neck of a container of the type mentioned, which can be adapted to smaller sizes of filler neck, such as those of urea tanks and yet has an optimal flow (volume per unit time) , without the risk of Rückstaubedingten shutdown of a fuel nozzle is given.
Zur Lösung dieser Aufgabe sind bei einem Filter der genannten Art die im Anspruch 1 angegebenen Merkmale vorgesehen.To solve this problem, the features specified in
Durch die erfindungsgemäßen Maßnahmen ist eine optimale Ausnutzung der Strömungseigenschaften von Flüssigkeiten bei deren Durchtritt durch den Filter und hierbei speziell dem Filterboden bei gleichzeitiger Verkleinerung der Filterbaugröße und einer Reduzierung von Turbulenzen erreicht. Die nachteiligen Eigenschaften bisher verwendeter Filter sind somit vermieden. Trotz der Bauraum- und Filterbaulängenreduzierung ist ein optimales Ausströmen der Flüssigkeit im Bodenausströmungsbereich gewährleistet. Außerdem ergibt sich eine Reduzierung der Kosten durch geringere, erforderliche Filtergewebeflächen bei gleichem Durchsatz- und Filtrationseigenschaften.The inventive measures optimal utilization of the flow characteristics of liquids in their passage through the filter and this particular filter bottom while reducing the filter size and a reduction of turbulence is achieved. The disadvantageous properties of previously used filters are thus avoided. Despite the space and Filterbaulängenreduzierung an optimal outflow of liquid is guaranteed in Bodenausströmungsbereich. In addition, there is a reduction in costs due to smaller, required filter fabric surfaces with the same throughput and filtration properties.
Vorteilhafte Ausgestaltungen derartiger Filtersiebe ergeben sich aus den Merkmalen eines oder mehrerer der Ansprüche 2 und/oder 3. Die Filtersiebe können also verschiedene Formen, wie dachkantförmige, prismatische, kegelförmige und/oder dergleichen besitzen.Advantageous embodiments of such filter screens result from the features of one or more of claims 2 and / or 3. The filter screens can therefore have different shapes, such as roof-shaped, prismatic, conical and / or the like.
Gemäß den Merkmalen nach Anspruch 4 ist es möglich, die zylindrische Wandung vor dem genannten Filtersieb flüssigkeitsundurchlässig auszubilden, ohne dass sich am vorerwähnten Durchströmverhalten durch das geneigt angeordnete Filtersieb etwas ändert.According to the features of claim 4, it is possible to form the liquid-impermeable cylindrical wall in front of said filter without any change in the above-mentioned flow through the inclined arranged filter screen.
Weitere Ausführungsbeispiele mit einer zumindest teilweise filtersiebartig ausgebildeten zylindrischen Wandung ergeben sich aus den Merkmalen eines oder mehrerer der Ansprüche 5 bis 7, mit dem Vorteil, dass die Flüssigkeitsströmung auf die seitlichen bzw. umfangsseitigen Filterflächen teilweise umgelenkt wird, was zu einer weiteren Optimierung des Durchsatzes der druckbelastenden Strömung und der Filterbaugröße führt.Further embodiments with an at least partially filter-like-like cylindrical wall arise from the features of one or more of claims 5 to 7, with the advantage that the liquid flow is partially deflected to the lateral or peripheral filter surfaces, resulting in a further optimization of the throughput of pressure-bearing flow and the filter size leads.
