Gegenstand der vorliegenden Erfindung . bildet ein Verfahren und eine Vorrichtung zum Abscheiden von Flüssigkeiten aus schlammigen Bestandteilen.Subject of the present invention. forms a method and an apparatus for separating liquids from sludgy components.
In der chemischen Großindustrie hat man es häufig mit größeren Mengen eines minderwertigen Abfallproduktes zu tun, welches seiner eigentümlichen Beschaffenheit wegen meistens mit dem Ausdruck Schlamm bezeichnet wird. Dieser Schlamm besteht zumeist aus feinem Salz, feinem Rückstand (unlöslichen Substanzen), Ton usw. und enthält eine gewisse Menge noch wertvoller Lauge. Diese Lauge zu gewinnen, gelingt wohl mittels Filterpressen, jedoch stehen die hohen Kosten dieses Verfahrens in keinem Verhältnis zu dem erzielten Resultat. Bei Verwendung von Nutschen wird das Filter durch die auflagernden Schlammteile leicht undurchlässig, es kann daher nur mit geringer Füllung gearbeitet werden, wobei leicht Risse entstehen, durch welche Luft durchgesaugt wird. Diese Übelstände werden durch vorliegendes Verfahren beseitigt, welches darin besteht, daß der Schlamm stark bewegt (gerührt oder geknetet) und ausgebreitet wird. Der Schlamm wird hierdurch mehr oder weniger dünnflüssig, die festen Bestandteile sinken nach unten und die Lauge scheidet sich an der Oberfläche ab. Die Lauge wird nach oben abgesaugt.In large-scale chemical industry, one often has to deal with large quantities of an inferior one To do waste product, which due to its peculiar nature is mostly referred to with the term sludge will. This mud mostly consists of fine salt, fine residue (insoluble substances), clay, etc. and contains a certain amount of even more valuable Lye. Obtaining this lye can be done using filter presses, but they stand The high cost of this procedure is out of proportion to the result achieved. at Using suction filters, the filter becomes light due to the sludge parts on top of it impermeable, it can therefore only be worked with a small amount of filling, with easy cracks arise through which air is sucked through. These evils are addressed by the present Eliminated process which consists in vigorously agitating the sludge or kneaded) and spread. This makes the sludge more or less fluid, the solid components sink to the bottom and the lye is deposited on the surface. The lye will sucked upwards.
Auf beiliegender Zeichnung ist ein Ausführungsbeispiel einer zweckentsprechenden Vorrichtung im Schnitt dargestellt.On the accompanying drawing is an embodiment of an appropriate one Device shown in section.
35" Der Trichter a, in welchen der Schlamm eingeführt wird, ist mit einem Rührwerk b versehen. Durch das letztere wird der Schlamm' ordentlich durchgeknetet und vermittels der Schnecke c auf den kegelförmig gestalteten Teller d befördert, welcher mit Vorsprängen, welche das seitliche Herauspressen des Schlammes erschweren, versehen ist. Oberhalb des Tellers d ist ein Filter e angeordnet, über welchem sich -ein geschlossener Raumy befindet. Dieser Raum f wird durch eine Luftpumpe luftleer gehalten, wodurch ein leichtes Ansaugen der Flüssigkeit erreicht wird. Die in den Raum f tretende Flüssigkeit wird durch Abflußöffnungen g ' abgeleitet. Der Teller rf ist auf der Welle/? fest aufgekeilt. Das Zahnrad i ist ebenso wie das Rührwerk b und die Schnecke c auf der mit Abflachungen versehenen Welle h so gelagert, daß bei Verschiebung der Welle h in der Achsenrichtung jene Teile ihre ursprüngliche Lage beibehalten, um die Wirkungsweise der' Maschine nicht zu beeinflussen. Zwecks Verschiebung der Welle h steht dieselbe an ihrem oberen Ende mit einer Schraubenspindel k in Verbindung. Die Verschiebung der Welle h hat den Zweck, den mit der Welle h fest verbundenen Teller d höher oder tiefer einstellen zu können.35 "The funnel a, into which the sludge is introduced, is provided with an agitator b . The sludge is thoroughly kneaded by the latter and, by means of the screw c, is conveyed to the conical plate d , which has protrusions which press it out sideways is of the sludge difficult provided. above the plate d, a filter is arranged e, above which there is -a closed Raumy. This space f is maintained evacuated by an air pump, whereby a slight suction of the liquid is achieved. the f in the space Any liquid that emerges is drained off through drainage openings g ' . The plate rf is firmly keyed on the shaft /? The gear wheel i , like the agitator b and the screw c, is mounted on the flattened shaft h in such a way that when the shaft h is displaced in the axial direction those parts keep their original position so as not to affect the operation of the machine The upper end of the shaft h is connected to a screw spindle k . The purpose of shifting the shaft h is to be able to set the plate d firmly connected to the shaft h higher or lower.
