KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Einrichtung der nachfolgend beschriebenen Extractionsvorrichtung liegt die Beobachtung zu Grunde, dafs nicht immer eine directe Berührung des Lösungsmittels mit dem Extractionsgut nothwendig ist, sondern dafs manchmal eine schnellere und vollständigere Extraction erzielt wird, wenn das Gut nur mit den heifsen Dämpfen des Lösungsmittels in Berührung kommt, da einerseits die Extracte schon hierdurch gelöst und genügend dünnflüssig werden, andererseits durch theilweise Condensation der Dämpfe in dem meist schlecht wärmeleitenden Extractionsgut eine vollständige Verflüssigung erzielt wird.The facility of the extraction device described below is responsible for the observation based on the fact that there is not always direct contact of the solvent with the Extraction is well necessary, but that sometimes a faster and more complete one Extraction is achieved when the material is only exposed to the hot vapors of the solvent Contact comes because on the one hand the extracts are already loosened and are sufficiently thin on the other hand by partial condensation of the vapors in the mostly Poor heat conducting Extractionsgut a complete liquefaction is achieved.
In beiliegender Zeichnung ist ein Apparat, der vorgenanntem Zwecke dienen soll, dargestellt. In the accompanying drawing, an apparatus which is intended to serve the aforementioned purpose is shown.
Der Apparat besteht im Wesentlichen aus dem Verdampfungsraum .B, dem Extractionsraum E, dem diese beiden Räume trennenden, aus geschlitztem Wellblech oder aus in geringen Abständen neben einander liegenden einzelnen Rinnen gebildeten schrägen Rost R, und dem schrägen, durch ein darüber befindliches Wasserbassin W' gekühlten Deckel A. Das neue Merkmal des Apparates liegt in der Errichtung des schrägen Rostes R. The apparatus consists essentially of the evaporation room B, the extraction room E, the inclined grate R, which separates these two rooms and is made of slotted corrugated iron or from individual channels lying next to one another at small intervals, and the inclined grate R, which is formed by a water basin W 'above. refrigerated lid A. The new feature of the device is the construction of the inclined grate R.
Der Apparat hat den Zweck, Fette und OeIe aller Art, Schwefel, Alkaloide u. s. w., aus den diese Substanzen enthaltenden Stoffen mit geeigneten Lösungsmitteln, wie z. B. Aether, Alkohol, Benzin, Schwefelkohlenstoff u. s. w., zu extrahiren, und zwar vornehmlich bei einer Temperatur, welche den Dämpfen dieser Lösungsmittel entspricht, bezw. durch die Lösungsmitteldämpfe selbst.The purpose of the apparatus is to remove fats and oils of all kinds, sulfur, alkaloids, etc., from the substances containing these substances with suitable solvents, such as. B. ether, Alcohol, gasoline, carbon disulfide, etc., to be extracted, primarily from one Temperature, which corresponds to the vapors of these solvents, respectively. through the solvent vapors themselves.
Das Extractionsgut wird zu diesem Zwecke durch das Mannloch M1 in den Raum E gebracht und das Lösungsmittel durch das Abschlufsorgan b in den Raum B geleitet. Mit Hülfe der Heizschlange h wird alsdann das Lösungsmittel verdampft, die dadurch erzeugten Dämpfe nehmen ihren Weg nach oben, durchdringen die Spalten des Rostes R und condensiren theils in dem auf letzterem ruhenden Extractionsgute, theils aber durchdringen, und zwar namentlich, wenn das Gut nach einiger Operationsdauer warm geworden ist, die Dämpfe das Gut und condensiren dann an dem Deckel A. For this purpose, the extraction material is brought into room E through manhole M 1 , and the solvent is passed into room B through closure element b . With the help of the heating coil h , the solvent is then evaporated, the vapors generated thereby take their way upwards, penetrate the cracks of the grate R and condense partly in the extraction good resting on the latter, but partly penetrate, namely when the good after some time The duration of the operation has become warm, the vapors remove the material and then condense on the lid A.
Letzterer liegt parallel zu dem schrägen Rost, damit das Extractionsgut eine gleich mäfsig starke Schicht bildet; ferner hat die schräge Lage des Deckels aber auch den bekannten weiteren Zweck, den gröfsten Theil des an der Fläche desselben gebildeten Condensats seitlich abzuführen und dadurch eine Kühlung des Extractionsgutes möglichst zu verhindern.The latter lies parallel to the inclined grate, so that the extraction material is uniform forms strong layer; furthermore, the inclined position of the lid also has the familiar one further purpose, the greater part of the condensate formed on the surface to the side and thereby prevent cooling of the extraction material as much as possible.
In den Räumen des schrägen Rostes R sammelt sich der gelöste Extract und läuft zusammen mit dem darin enthaltenen bezw. in dem Extractionsgut condensirten Lösungsmitteldämpfen in die querliegende Sammelrinne 5, welche die Flüssigkeit sodann nach den seitlichen Wandungen des Apparates leitet.The dissolved extract collects in the spaces of the inclined grate R and runs together with the contained therein or. Solvent vapors condensed in the extraction material into the transverse collecting channel 5, which then conducts the liquid to the side walls of the apparatus.
Auf diese Weise wird verhindert, dafs die im Verdampfraume erzeugten Lösungsmitteldämpfe mit der abwärtslaufenden Flüssigkeit zusammentreffen und von letzterer niedergeschlagen werden.This prevents the solvent vapors generated in the evaporation space meet with the downward running liquid and knocked down by the latter will.
Während der Extractionsdauer tritt durch die Rohre n> und rx kaltes Wasser in das Bassin W und kühlt dadurch den Deckel A, während das erwärmte Wasser bei α abläuft.During the extraction period, cold water passes through the pipes n> and r x into the basin W and thereby cools the cover A, while the heated water runs off at α .
Ist die Extraction beendet und soll das Lösungsmittel behufs Wiedergewinnung aus dem Extractionsrückstande ausgetrieben werden, so öffnet man das bis dahin geschlossen gehaltene Absperrorgan C1, stellt den Kühlwasserzulauf ab und läfst behufs Erwärmung des Deckels A Dampf durch das Rohr rl in das Wasserbassin W treten.Is the Extraction terminated and to the solvent behufs recovery are expelled from the Extractionsrückstande, so opening the previously closed held shut-C 1 provides the cooling water inlet, and läfst behufs heating of the cover A steam through the pipe r l in the water basin W contact .
Gleichzeitig wird mit Hülfe der Dampfschnatterrohre r2 directer Dampf durch die Rostspalten nach E geleitet und dadurch das Lösungsmittel aus dem Rückstande ausgetrieben, welches, weil es an dem nunmehr heifsen Deckel nicht mehr condensirt wird, seinen Weg in Dampfform durch C1 bezw. C nach dem Condensator nimmt, um in üblicher Weise wieder verflüssigt zu werden.At the same time, with the help of the steam chopper tubes r 2 direct steam is passed through the grate gaps to E and the solvent is driven out of the residue, which, because it is no longer condensed on the now hot cover, makes its way in vapor form through C 1 and C 1, respectively. C after the condenser takes to be liquefied again in the usual way.
Der Rückstand wird nach beendeter Austreibung durch das Mannloch Ot2 entfernt und der Extract durch χ abgelassen.After the expulsion is complete, the residue is removed through the manhole Ot 2 and the extract is drained off through χ.
gg sind Schaugläser zur Beobachtung des Vorganges in B. gg are sight glasses for observing the process in B.
