KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bekannt, daß es zur Beschleunigung der in Wasserenthärtungsapparaten zu erzielenden chemischen Vorgänge beiträgt, wenn dem Rohwasser, bevor es in den Mischraum gelangt, in dem ihm die Sodalauge und das Kalkwasser beigemengt werden, zuvor etwas von dem sich im untersten Teile des Klärbehälters sammelnden Schlamme beigemischt wird. Bei anderen WasserreinigungsapparatenIt is known that it can be used to speed up the amount of water to be achieved in water softeners chemical processes when the raw water, before it gets into the mixing room, in which it contains the soda lye and the Lime water must be added, beforehand some of it is in the lowest part of the clarification tank is added to collecting sludge. With other water purification devices

ίο lassen sich in bekannter Weise ähnliche Wirkungen erzielen, wenn dem Wasser, bevor es in den Klärbehälter eintritt, Klärschlamm aus dem unteren Teile des Klärbehälters zugemischt wird.ίο can have similar effects in a known manner Achieve when the water, before it enters the septic tank, sewage sludge from is added to the lower part of the clarifier.

Gegenstand der vorliegenden Erfindung ist nun eine Vorrichtung, mittels der in neuer und einfacher Weise diese Beimischung herbeigeführt wird. Die Erfindung besteht darin, daß ein Teil des Rohwassers durch die Leitung α einem Fallrohre b zugeführt wird und bei seinem Einfallen in dasselbe Luft mit hineinreißt. Wenn die obere Mündung des Rohres b höher liegt als der Wasserspiegel im Klärbehälter, so fällt das mit Luft gemischte Rohwasser in dem Rohr b herab, gelangt in das Gefäß c und steigt von dort in dem Rohre g, das das Rohr b umgibt oder außerhalb desselben liegt, wieder empor. Auf diese Weise wird das Rohr g mit einem Luft- und Wassergemisch gefüllt, dessen spezifisches Gewicht geringer ist als das des Wassers, so daß sich der Wasserspiegel im Rohre g, das durch Rohr d mit dem unteren Teil des Klärbehälters in Verbindung steht, höher einstellt als in letzterem, und daß ferner das Wasser in g aufwärts strömt.The present invention now relates to a device by means of which this admixture is brought about in a new and simple manner. The invention consists in that part of the raw water is fed through the line α to a downpipe b and, when it falls into the same air, is carried along with it. If the upper mouth of the pipe b is higher than the water level in the clarification tank, the raw water mixed with air falls down in the pipe b , gets into the vessel c and rises from there in the pipe g that surrounds the pipe b or outside it lies up again. In this way, the pipe g is filled with a mixture of air and water, the specific weight of which is lower than that of the water, so that the water level in pipe g, which is connected to the lower part of the clarification tank through pipe d, is higher than in the latter, and that furthermore the water flows upwards in g.

Dieses wird über den oberen Rand des Klärbehälters weg mittels des Rohres h in den Mischraum i gehoben. Durch die Wasserströmung in g wird auch das Wasser in d mitgerissen, und dieses reißt Schlammteilchen aus dem Klärbehälter bei e mit, die dann ebenfalls durch g und h nach i gelangen und dort in der beabsichtigten Weise dem Rohwasser beigemengt werden.This is lifted over the upper edge of the clarification tank by means of the pipe h into the mixing room i. The water flow in g also entrains the water in d , and this carries away sludge particles from the clarification tank at e , which then also pass through g and h to i and are added to the raw water in the intended way.
