Die Wirkungsweise der Filtervorrichtung 1st folgende:The mode of operation of the filter device is as follows:

Die zu filternde Flüssigkeit, d.h. das Wasser tritt in die Filterkolonne, die von dem Gehäuse E1 umgeben ist,, so ein, wie es durch die Pfeile 22 dargestellt Ist. Bis gesamte Durehfluömenge tritt in die Filterelemente 10, 10' mit dem größten Durchmesser der ersten Stufe A* ein, die an Eingang der Filterkolonne angeordnet sind0 Ein Teil der DurchfluSaenge durchläuft die Filterwand der Elemente, vie dies durch des Pfeil 1? angedeutetThe liquid to be filtered, ie the water, enters the filter column, which is surrounded by the housing E 1 , as shown by the arrows 22. A bis entire Durehfluömenge enters the filter elements 10, 10 'with the largest diameter of the first stage A *, which are arranged at the input of the filter column 0 A portion of the DurchfluSaenge passes through the filter wall of the elements, this vie by the arrow 1? indicated

lnt, um das gefilterte Wasser zu liefern« das aus der Kolonne bei 20 auetritt. Der Rest der Durchflußmenge tritt in die folgende Stufe B' ein« aus der in gleicher Weise das gefilterte Waaeer entlang des Pfeiles 18 austritt und die Kolonne bei verläßt. Der verbleibende Teil der Durchflußmenge tritt in die dritte Stufe C1 ein und verläßt diese vollständig gefiltert entlang des Pfeiles 19* Int to deliver the filtered water that emerges from the column at 20. The remainder of the flow rate enters the following stage B 'from which the filtered water emerges in the same way along the arrow 18 and leaves the column at. The remaining part of the flow rate enters the third stage C 1 and leaves it completely filtered along the arrow 19 *

Di· drei duroh die drei Stufen gefilterten Durchflußmengen vermischen sich und ergeben am strömungsabwärts gelegenen Ende des Gehäuses E1 (oder am strönmngsabwärts gelegenen Ende der Filtervorrichtung wenn kein Gehäuse vorgesehen 1st) die gefilterte Flüssigkeit, die durch den Pfeil 20 angedeutet ist«.The three flow rates filtered through the three stages mix and give the filtered liquid indicated by arrow 20 at the downstream end of the housing E 1 (or at the downstream end of the filter device if no housing is provided).

Aus dein Vorstehenden ist su erkennen, daß die drei Stufen A', B' und C1 parallel wirken und daß sich daher die gefilterten Durohflußmengen pro Stufe addieren. Zum besseren Verständnis der parallelen Wirkungswelse der Filterelemente» beispielsweise IQ,, 11 und 12 können gedachte Ubertragungsrohre angenommen werden, die sich in Verlängerung der Filterelemente der unteren Stufen nach oben erstrecken. Die Dir chflußmenge 17 entspricht damit dem Volumen, das zwischen dem gedachten Rohr mit dem größten Durchmesser und der Filterwand des Elementes 10 liegt, die Durchflußmenge 18 entspricht dem Volumen, das zwischen den beiden gedachten Rohren mit den größten Durchmessern liegt und göhließlich entspricht die Burchflußmenge 19 dem Volumen des gedachten Rohres mit dem kleinsten Durchmesser.From what has been said above, it can be seen that the three stages A ', B' and C 1 act in parallel and that the filtered durometer flow rates per stage therefore add up. For a better understanding of the parallel functioning of the filter elements, for example IQ, 11 and 12, imaginary transmission pipes can be assumed which extend upwards as an extension of the filter elements of the lower stages. The flow rate 17 corresponds to the volume that lies between the imaginary tube with the largest diameter and the filter wall of the element 10, the flow rate 18 corresponds to the volume that lies between the two imaginary tubes with the largest diameter and ultimately corresponds to the flow rate 19 the volume of the imaginary pipe with the smallest diameter.
