 Wirkung ergibt. Man kann somit die unteren, stärker geneigten Abschnitte der parabelförmigen Lamellen weglassen, wie dies in Fig. 2 dargestellt ist. Der Abstand der Lamellen voneinander sowie die Höhe und die Breite derselben bestimmen die Absetzwirkung. Man kann daher derartige Leitbleche (Lamellen) auch als Grobsandfänge vor Kanalflachstrecken einbauen, was sich bewährt hat. 



   Eine Einbaugarnitur gemäss der Erfindung besteht aus zwei Längsholmen T (Fig. 3), an die die Leitbleche angeschweisst sind. Fig. 4 stellt den Einbau beim Sandfang S dar. Für den Einbau in bestehende Anlagen, der durchaus möglich ist,. sind bloss die notwendigen Haltevorrichtungen anzubringen. 



    PATENTANSPRÜCHE :    
1. Sandfang für Abwasserkläranlagen mit einem Lamellenrost zwischen Sandfangraum und Durchflussteil, dessen Lamellen quer zur Strömungsrichtung verlaufen, dadurch gekennzeichnet, dass die Lamellen mit Neigung von unten nach oben in der Strömungsrichtung angeordnet sind, wobei die Länge der Lamellenquerschnitte in Strömungsrichtung, die Höhe der Lamellenquerschnitte quer zur Strömungsrichtung sowie der Kantenabstand der Lamellen in Strömungsrichtung entsprechend der angestrebten Absetzwirkung gewählt sind.

 Effect. The lower, more inclined sections of the parabolic lamellae can thus be omitted, as shown in FIG. The distance between the lamellas and the height and width of the same determine the settling effect. You can therefore install such baffles (lamellas) as coarse sand traps in front of channel flat sections, which has proven itself.



   An installation set according to the invention consists of two longitudinal spars T (Fig. 3) to which the guide plates are welded. Fig. 4 shows the installation in the sand trap S. For installation in existing systems, which is entirely possible. only the necessary holding devices have to be attached.



    PATENT CLAIMS:
1. Sand trap for sewage treatment plants with a lamellar grate between the sand trap area and the flow part, the lamellae of which run transversely to the direction of flow, characterized in that the lamellae are arranged with an incline from bottom to top in the direction of flow, the length of the lamella cross-sections in the flow direction, the height of the lamellar cross-sections transversely to the direction of flow and the distance between the edges of the lamellas in the direction of flow are selected according to the desired settling effect.

Claims (1)
