Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezieht sich auf einen Siebkopf für das Abflufsrohr von Filterbehältern, welcher so construirt ist, dafs bei Umkehrung der Bewegungsrichtung des Wassers, behufs Auswaschens des Filters, das Wasser nach allen Richtungen in dem Filterbett gut vertheilt wird, so dafs das letztere heftig aufgerührt wird und "das Wasser während der Filtration von allen Seiten zu dem Siebkopf gelangen kann. Die Anordnung kennzeichnet sich besonders dadurch, dafs in dem Siebkopf seitliche schräge Durchlässe vorgesehen sind, welche infolge ihrer Lage von dem Gewicht des Filterbettes unbeeinflufst sind und das Eintreten des Wassers in den Siebkopf erleichtern. Selbstverständlich müssen die Siebeinlässe des Siebkopfes einen Gesammtquerschnitt besitzen, welcher dem Querschnitt des das Wasser wegleitenden Rohres entspricht.The present invention relates to a sieve head for the drain pipe of filter containers, which is so constructed that when the direction of movement of the water is reversed, for washing out the filter, the water is well distributed in all directions in the filter bed so that the latter is vigorously stirred up, and "the water during the filtration can reach the sieve head from all sides. The arrangement is particularly distinctive in that lateral inclined passages are provided in the sieve head, which due to their location are unaffected by the weight of the filter bed and that Make it easier for the water to enter the sieve head. Of course, the sieve inlets must of the sieve head have a total cross-section which corresponds to the cross-section of the corresponds to the water leading away pipe.
Auf der beiliegenden Zeichnung ist eine Ausfuhrungsform der Erfindung dargestellt.An embodiment of the invention is shown in the accompanying drawing.
Fig. ι ist ein Verticalschnitt durch einen Filterbehälter.Fig. Ι is a vertical section through a filter container.
Fig. 2 ist eine Ansicht desselben von oben.Fig. 2 is a top view of the same.
Fig. 3 bis 5 zeigen den Siebkopf im Detail.3 to 5 show the sieve head in detail.
Der Filterbehälter α ist mit einer beliebigen Filtermasse angefüllt. Zur Ableitung des gereinigten Wassers dient das Rohr b, welches durch einen oder mehrere Zweige c mit einem am Boden des Behälters α angeordneten Rohr d in Verbindung steht (Fig. 1 und 2). Letzteres besitzt eine Anzahl Zweigröhren e, welche mit Siebköpfen f (Fig. 3 bis 5) besetzt sind. Diese Siebköpfe bestehen aus einem Konus g mit einem Schraubenstutzen h, mittelst dessen sie auf die Röhren aufgeschraubt sind. Auf dem Konus sitzt ein Deckel i, dessen mittlerer Theil nach unten eingedrückt ist, so dafs der Deckel einen M - förmigen Querschnitt besitzt (Fig. 3). Der mittlere Theil des Deckels ist nicht durchlocht und etwas verstärkt, um den aufwärts gehenden Strom des Waschwassers nach dem Rande hin abzulenken. Nach dem Rande zu sind die Siebkopfdeckel mit gebogenen oder umgekehrt V-förmigen Schlitzen k (Fig. 3) versehen, so dafs bei der Filtration das Wasser von den Seiten her eintritt, und beim Waschen die Köpfe von der Seite her verläfst. Hierdurch wird erzielt, dafs das Gewicht der Filtermasse auf das ein- und austretende Wasser nur wenig wirkt, so dafs der Durchflufs des Wassers durch die Siebkopfmündungen erleichtert wird.The filter container α is filled with any filter material. The pipe b is used to discharge the purified water, which is connected by one or more branches c to a pipe d arranged at the bottom of the container α (FIGS. 1 and 2). The latter has a number of two tubes e, which are equipped with sieve heads f (Fig. 3 to 5). These sieve heads consist of a cone g with a screw socket h, by means of which they are screwed onto the tubes. On the cone sits a lid i, the middle part of which is pressed in downwards so that the lid has an M-shaped cross-section (Fig. 3). The middle part of the lid is not perforated and is somewhat reinforced, in order to divert the upward flow of the washing water towards the edge. Towards the edge, the sieve head covers are provided with curved or inverted V-shaped slots k (FIG. 3), so that the water enters from the sides during filtration and leaves the heads from the side during washing. This ensures that the weight of the filter material has only a slight effect on the water entering and exiting, so that the flow of water through the mouth of the sieve head is facilitated.
