KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die vorliegende Erfindung hat den gleichen Zweck, wie die durch die Patentschrift Nr. 34034 bekannt gewordene Neuerung: continuirliche Entfernung des in Vacuumverdampfern ausgeschiedenen Salzes, ohne hierbei das Vacuum abstellen zu müssen.The present invention has the same purpose as that of Patent No. 34034 known innovation: continuous removal of the precipitated in vacuum evaporators Without having to turn off the vacuum. Bei Patent Nr. 34034 wird dies durch ein barometrisches Abfallrohr erreicht,, in ähnlicher Weise, wie bei hochstehenden Gegenstromcondensatoren das Wasser abgeführt wird, bei vorliegender Erfindung jedoch mit Hülfe eines mechanischen Rührwerks.In Patent No. 34034 this is accomplished through a barometric waste pipe, similarly Way how the water is drained off in the case of upright countercurrent condensers present invention, however, with the aid of a mechanical agitator. In den Untertheil des Apparates, welcher die dargestellte eigenfhümliche Form erhält, ist ein Rührwerk R eingebaut, dessen Schaufeln sich der Gefäfsform genau anpassen. Mittelst Winkelräder und einer Welle, die gegen die Atmosphäre durch eine Stopfbüchse abgedichtet ist, wird das Rührwerk in Umdrehung versetzt, und zwar mit einer Umfangsgeschwindigkeit v, die sich aus der Beziehung ergiebt:In the lower part of the apparatus, which has the peculiar shape shown, an agitator R is built in, the blades of which adapt exactly to the shape of the vessel. By means of angular gears and a shaft, which is sealed against the atmosphere by a stuffing box, the agitator is set in rotation, namely with a peripheral speed v, which results from the relationship:
