Description

Sandsäulenfilter.Sand column filter.

Die Neuerung besteht in der Anordnung eines schraubengangförmigen Rohwasserraumes f in einem offenen oder geschlossenen Filtergefäß a mit rundem oder eckigem Querschnitt, und zwar dergestalt, daß an der inneren Wand des Gefäßes a eine Rippe e in Schraubengängen eingebaut ist. Beschickt man nun das Gefäß, in dessen Mitte sich der Reinwasserraum mit dem Abflußrohr c befindet, mit Filtermaterial, z. B. Kies oder Sand, so fällt es in seinem Böschungswinkel unter die Rippenunterfläche und läßt dabei einen schraubenförmig gewundenen Hohlraum t offen, der den Rohwasserraum des Filters bildet. The innovation consists in the arrangement of a helical Raw water space f in an open or closed filter vessel a with a round or angular cross-section, in such a way that on the inner wall of the vessel a a rib e is built into screw threads. If you now load the vessel in which In the middle is the clean water room with the drain pipe c, with filter material, z. B. gravel or sand, it falls in its angle of repose below the rib surface and leaves a helically wound cavity t open, which forms the raw water space of the filter.

Die zu filtrierende Flüssigkeit fließt dann vom Einlauf b bis zum Spülauslaß d durch die schraubenförmig gewundene Oberfläche des Filtermaterials, auf der es die Schmutzteile zurückläßt, radial nach dem Reinwasserraum g in der Gefäßmitte und dem Abfluß c. The liquid to be filtered then flows from inlet b to Flush outlet d through the helically wound surface of the filter material, on which it leaves the dirt, radially after the clean water room g in the Middle of the vessel and the drain c.
