Abstract
Description
Filter für Aquarien und dgl.Filters for aquariums and the like.
Die Neuerung betrifft einen Filter für Aquarien, kleine Weiche und dgl. mit einem im wesentlichen hohlzylindrischen, aus Schaumstoff od. dgl. bestehenden Filterkörper zur radialen Durchströmung.The innovation concerns a filter for aquariums, small switches and Like. With a substantially hollow cylindrical, made of foam or the like. Existing Filter body for radial flow.
Bei bekannten Filtern dieser Ausführung liegt die Aussenfläche des Filterkörpers frei; eine solche Anordnung ist Jedoch nur dann möglich, wenn die Filtereinrichtung saugseitig angeordnet ist.In known filters of this design, the outer surface of the Filter body free; However, such an arrangement is only possible if the Filter device is arranged on the suction side.
Der Neuerung liegt im wesentlichen die Aufgabe zugrunde, die obigen Filter so auszubilden, dass sie auch druckseitig betrieben werden können, indem das zu filternde Wasser dem Filter unter einem gewissen Drucb ugeführt wird, und zwar in der Weise, dass eine radiale Durchdringung des Filterkörpers möglich ist.The innovation is essentially based on the task above To train filters so that they can also be operated on the pressure side by the water to be filtered is fed to the filter under a certain pressure, and in such a way that radial penetration of the filter body is possible.
Zur Lösung dieser Aufgabe ist gemäss der Neuerung die Aussenkontur des Filterkörpers nach Art eines Polygonzuges mit vier bis acht, vorzugsweise aber mit fünf bis sieben Ecken gestaltet, während die Innenfläche des Filtergehäuses gleichmässig gekrümmt bzw. zylindrisch gestaltet ist in der Weise, dass sich kreisabschnittähnliche Steigräume ergeben, in denen das Wasser aufsteigt, um von dort aus radial durch den Filterkörper zu gelangen.According to the innovation, the outer contour is the solution to this task of the filter body in the manner of a polygon with four to eight, but preferably designed with five to seven corners, while the inner surface of the filter housing is designed to be uniformly curved or cylindrical in such a way that it is similar to a segment of a circle Rises result in which the water rises to radially through from there to get to the filter body.
Eine solche Ausbildung des Filters hat den grossen Vorteil, dass sich der Filterkörper innerhalb des Gehäuses selbst zentriert hält. Zugleich wird eine spezifisch gleichmässige Durchdringung des Filterkörpers erreicht. Dies hat wiederum eine grosse Standzeit des Filterkörpers zur Folge. Darüber hinaus ist aber auch sichergestellt, dass ein vergleichsweise grosser Durchsatz erreicht werden kann.Such a design of the filter has the great advantage that the filter body keeps itself centered within the housing. At the same time becomes a specific uniform penetration of the filter body is achieved. This in turn has a big one Resulting in service life of the filter body. In addition, it is also ensured that a comparatively large throughput can be achieved.
Weitere Einzelheiten der Neuerung werden anhand der Zeichnung erläutert, in der ein vorzugsweise zur Anwendung kommendes Ausführungsbeispiel dargestellt ist.Further details of the innovation are explained using the drawing, in which an exemplary embodiment that is preferably used is shown is.
Es zeigen Fig. 1 einen senkchten Schnitt durch einen Innenfilter für Aquarien und Fig. 2 einen Schnitt nach der Linie II - II von Fig. 1.1 shows a vertical section through an internal filter for Aquariums and FIG. 2 shows a section along the line II - II from FIG. 1.
Das druckfeste Filtergehäuse 1 besteht aus einem geeigneten Kunststoff, es hat einen Boden 2 und einen abnehmbaren Deckel 3, der zum Aufnehmen des Filters entfernt werden kann. Das Filtergehäuse 1 hat unten im Boden 2 einen Zufluss 4 und oben im Deckel 5 in zentraler Lage einen Abflusstutzen 5.The pressure-resistant filter housing 1 consists of a suitable plastic, it has a bottom 2 and a removable cover 3 which is used to hold the filter can be removed. The filter housing 1 has an inlet 4 and in the bottom 2 In the top of the cover 5, a drainage nozzle 5 in a central position.
Im Abstand vom Boden 2 befindet sich innerhalb des Filtergehäuses 1 eine Querwand 6 mit seitlich aussen gelegenen Durchtrittsöffnungen 7, die der Aussenwand des Filtergehäuses 1 unmittelbar benachbart liegen.At a distance from the bottom 2 is located inside the filter housing 1 a transverse wall 6 with laterally outside passage openings 7, which the The outer wall of the filter housing 1 are immediately adjacent.
Die Filterung erfolgt mittels Filterkörper 8 in Form einer sog. Kunststoffpatrone, die aus einem weichieingestellten Kunststoffschaum bestehen kann. Der Filterkörper 8 hat eine zentrale Bohrung 9, die oben in den Abflusstutzen 5 mündet und unten durch die Querwand 6 verschlossen ist.The filtering takes place by means of a filter body 8 in the form of a so-called plastic cartridge, which can consist of a plasticized plastic foam. The filter body 8 has a central bore 9 which opens into the drainage connection 5 at the top and at the bottom is closed by the transverse wall 6.
Im wesentlichen kennzeichnend für die besondere Ausbildung des Filters ist die polygonartige Aussenkontur des Filterkörpers 8 mit den sich go bildenden Ecken lo die im wesentlichen an der zylindrischen Innenfläche }1 des Filtergehäuses 1 anliegen und so Steigräume 12 bilden, die einerseits durch die Aussenwandung des.Essentially indicative of the special design of the filter is the polygonal outer contour of the filter body 8 with the go forming Corners lo the substantially on the cylindrical inner surface} 1 of the filter housing 1 rest and thus form riser spaces 12, which on the one hand by the outer wall of the.
Filtergehäuses 1 und andererseits durch die Polygonflächen 13 begrenzt sind, die ihrerseits wegen des symmetrischen Polygons alle von gleicher Länge sind.Filter housing 1 and on the other hand limited by the polygon areas 13 which in turn are all of the same length because of the symmetrical polygon.
Wie aus der Zeichnung erkennbar ist, strömt das zu filternde Wasser unter Druck von unten nach oben im Sinne der-Pfeile. Es gelangt nach der Filterung in die Bohrung 9 und von dort aus in den Abflusstutzen 5, von dem aus das Wasser über beliebige Leitungen fortgeleitet werden kann.As can be seen from the drawing, the water to be filtered flows under pressure from bottom to top in the direction of the arrows. It arrives after filtering into the bore 9 and from there into the drainage nozzle 5, from which the water can be forwarded via any lines.
Aufgrund von Versuchen hat sich ergeben, dass ein regelmässiges Sechseck gemäss Fig. 2 die besten Ergebnisse bringt. Bei dieser Formgebung entstehen bei guter Werkstoffausnutzunjgut bemessene Querschnitte für die kanalartigen Steigräume 12.Tests have shown that a regular hexagon according to FIG. 2 brings the best results. With this shape arise at good utilization of material, well dimensioned cross-sections for the channel-like risers 12th
