Description

Verdampfer mit Kettenrührwerk.Evaporator with chain agitator.

Die Erfindung betrifft eine Vorrichtung, um schäumende Flüssigkeiten, insbesondere Ölemulsionen, wie Rohöle, Rückstandsöle, Ablauföle aus Putzstoffen und von Kraftmaschinen, zu entwässern. The invention relates to a device for foaming liquids, in particular oil emulsions, such as crude oils, residual oils, drainage oils from cleaning materials and from prime movers to drain.

Derartige Emulsionen schäumen stark beim \ erdampfen des Wassers, und der Schaum ist, namentlich bei viskosen Schmierölen (Zylinderölen u. dgl.), sehr beständig. Außerdem pflegen die darin vorhandenen Verunreinigungen die Heizfläche des Verdampfers mehr oder weniger schnell zu verlegen. Die mehrfach dafür vorgeschlagenen Rieselverdampfer bewirken ein lästiges Verspritzen und lassen mit zunehmender Verunreinigung der Heizfläche in der Wirkung nach. Infolgedessen ist das Auskochen bisher eine unangerlehme, zeitraubende Arbeit, die besondere Sorgfalt erfordert. Such emulsions foam strongly when the water evaporates, and the foam is, especially in the case of viscous lubricating oils (cylinder oils, etc.), very consistent. In addition, the impurities in it maintain the heating surface to relocate the evaporator more or less quickly. The ones proposed several times for this Trickle evaporators cause annoying splashing and leave with increasing contamination the effect of the heating surface. As a result, the boil-out has so far been one inconvenient, time-consuming work that requires special care.

Diesen lMelständen begegnet die Brfindung durch ein Kettenrührwerk, dessen Ketten die Schaumoherfläche fortgesetzt durchschneiden, um den Schaum zu zerstören. Ketten haben sich für diesen Zweck als sehr wirksam und handlich erwiesen und ergeben eine besonders einfache und wohlfeile Herstellung der Rührwerke. Diese lassen sich leicht so einrichten, daß die Ketten in an sich bekannter Weise auf dem Boden des Verdampfers schleppen und so die Heizfläche reinhalten. The discovery counteracts these problems by means of a chain agitator, whose chains continue to cut through the foam surface in order to close the foam destroy. Chains have proven to be very effective and handy for this purpose and result in a particularly simple and inexpensive manufacture of the agitators. These can be easily set up so that the chains in a known manner dragging them to the bottom of the evaporator and thus keeping the heating surface clean.

Die Zeichnung zeigt einige Ausführungsbeispiele, und zwar in Fig. I und) runde, in Fig. 3 und 4 einen muldenförmigen Verdampfer. a ist der Kocher, b dessen Heizfläche, c die Schaumoberfläche der kochenden Flüssigkeit, d die Rührwelle mit Antrieb, e der Ketten träger, f die Rührketten. The drawing shows some exemplary embodiments, specifically in Fig. I and) round, in Fig. 3 and 4 a trough-shaped evaporator. a is the stove, b its heating surface, c the foam surface of the boiling liquid, d the stirrer shaft with drive, e the chain carrier, f the agitator chains.

In Fig. I links reichen die Ketten nur in die schäumende -Flüssigkeit, in Fig. 1 rechts schleppen sie auch am Boden. In Fig. I on the left, the chains only extend into the foaming liquid, In Fig. 1 on the right they also drag on the ground.

Fig. 2 zeigt besondere Ketten f' mit Träger e' zum Zerstören des Schaumes und andrerseits f mit Träger e zum Reinhalten der Heizfläche. Links sitzen sie auf gemeinsamer Rührwelle, -rechts sind besondere Wellen d' und d vorgesehen, um die beiden Kettenträger e' und e mit verschiedener Geschwindigkeit und in entgegengesetzter Richtung umlaufen zu lassen. Fig. 2 shows special chains f 'with carrier e' for destroying the Foam and on the other hand f with support e to keep the heating surface clean. Sit on the left they are on a common agitator shaft, special shafts d 'and d are provided on the right, around the two chain carriers e 'and e at different speeds and in opposite directions To revolve direction.

Bei dem muldenförmigen Kocher (Fig. 3 und 4) Sitzt zwischen den Wellenzapfen d, d ein liegender Rahmen g, e, an dessen Längsseiten e die Ketten f frei drehbar herabhängen. In the case of the trough-shaped cooker (FIGS. 3 and 4) it sits between the shaft journals d, d a lying frame g, e, on whose long sides e the chains f are freely rotatable hang down.

Diese Ausführung ergibt ein besonders gutes Durchmischen des Kocherinhaltes. Außerdem nehmen die bei jeder - Umdrehung aus der Flüssigkeit heraustretenden Kettenstücke den Schaum mit in die Höhe. Beim Herabfließen an den Ketten platzen die Schaumblasen und außerdem wirken die heraustretenden Kettenstücke als ständig sich erneuernde verdampfende Oberfläche. So begünstigt diese Ausführung die Verdampfung in verschiedener Hinsicht. This design results in particularly good mixing of the contents of the digester. In addition, take the pieces of chain emerging from the liquid with every revolution the foam up with it. The foam bubbles burst as they flow down the chains and, moreover, the protruding pieces of chain act as constantly renewing oneself evaporating surface. So this design favors evaporation in various ways Respect.
