Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Abwässerreinigungsanlage, welche aus einem Absetzraum mit darunter befindlichem Schlammfaulraum besteht, wobei beide Räume gegeneinander abgeschlossen sind.The present invention relates to a wastewater treatment plant, which from a sedimentation room with a sludge digestion room underneath exists, whereby both rooms are closed against each other.
Das Neue besteht darin, daß der Verschlußkörper als Schaufelwalze ausgebildet ist, die durch den niedersinkenden Schlamm in Drehung versetzt wird und den Schlamm ununterbrachen dem Faulraum zuführt.The novelty is that the closure body is designed as a paddle roller, which is set in rotation by the sinking mud and the mud is uninterrupted feeds to the septic tank.
Auf der Zeichnung ist die Vorrichtung in schematischem Schnitt durch Absetzkammer und Faulraum veranschaulicht.In the drawing, the device is a schematic section through the settling chamber and septic tank illustrated.
Der Absetzraum a, in welchen das frische Abwasser eintritt, mündet in der gezeichneten beispielsweisen Ausführungsform in den tieferen Schlammsammel- bzw. Faulraum h. Mittels schräger Abgleitfläche f wird der sich in α absetzende Schlamm abwärts zu einem spaltförmigen Schlammdurchgang c geleitet, der in den Faulraum hineinragt. In dem Durchlaß c befindet sich die Schaufelwalze s, die von dem sich oberhalb anstauenden Schlamm gedreht wird und diesen gleichmäßig nach unten zum Faulraum weiterfördert.The settling space a, into which the fresh wastewater enters, opens into the deeper sludge collection or digestion space h in the exemplary embodiment shown. By means of an inclined sliding surface f , the sludge settling in α is directed downwards to a slit-shaped sludge passage c, which protrudes into the digester. In the passage c is the paddle roller s, which is rotated by the sludge accumulating above and conveys it evenly down to the digester.
Damit das Abgleiten des Schlammes erleichtert wird, ist die Schrägfläche f vorteilhaft mit Glasplatten, mit glasierten Tonfliesen o. dgl. glattem Belag versehen. Dadurch wird die Reibung, welche sonst den aus der Schlammbelastung resultierenden Abwärtsdruck herabsetzen würde, wesentlich vermindert.In order to facilitate the sliding of the sludge, the inclined surface f is advantageously provided with glass plates, with glazed clay tiles or similar smooth covering. This significantly reduces the friction which would otherwise reduce the downward pressure resulting from the sludge loading.
Die Drehung der Schaufelwalze s kann durch einen mechanischen Antrieb, z. B. durch ein Kettengetriebe k mit Rädern k1, k2, unterstützt werden.The rotation of the paddle roller s can be controlled by a mechanical drive, e.g. B. be supported by a chain transmission k with wheels k 1 , k 2 .
