Verfahren zum Lösen von Kalirohsalzen. Patentiert im Deutschen Reiche vom 12. Februar 1907 ab. Process for dissolving crude potash salts. Patented in the German Empire on February 12, 1907.
Die Erfindung betrifft ein Verfahren, nach welchem Kalirohsalze derart gelöst werden, daß nicht nur die Löseflüssigkeit, sondern auch die zu lösenden Salze und der verbleibende Rückstand kontinuierlich mechanisch zu- bzw. abgeführt werden.The invention relates to a method by which crude potash salts are dissolved in such a way that not only the dissolving liquid, but also the salts to be dissolved and the remaining one Residue are continuously fed in or removed mechanically.
Der in Fig. ι bis 3 dargestellte, zur Ausführung des Verfahrens dienende Löseapparat ist durch Scheidewände E in mehrere Abteile geteilt.The release apparatus shown in FIGS. 1 to 3 and used to carry out the method is divided into several compartments by partitions E.
In jedem Abteil rotiert eine aus gelochtem Eisenblech gefertigte Lösetrommel L. A loosening drum L made of perforated sheet iron rotates in each compartment.
Die Trommeln besitzen an den Innenwandungen Schneckengänge, welche das Lösegut fortbewegen.The drums have screw flights on the inner walls, which hold the solids move around.
Die zwischen den Löseabteilungen befindlichen Scheidewände haben verstellbare Durchlaßöffnungen b, welche zwar das Lösegut durchlassen, aber ein weitgehendes Vermischen der in den einzelnen Abteilen befindlichen, verschieden schweren Laugen verhindern.The partitions located between the dissolving compartments have adjustable passage openings b, which allow the dissolving material to pass through, but prevent extensive mixing of the alkaline solutions of different weights in the individual compartments.
Wird der Apparat zur entsprechenden Höhe mit Löselauge gefüllt, diese durch einströmenden Dampf genügend erhitzt und gelangt kalihaltiges Rohsalz nach zweckmäßiger Zerkleinerung ununterbrochen in die erste Lösetrommel bei a, so wird es durch Rotieren der Trommel fortbewegt.If the apparatus is filled to the appropriate level with dissolving solution, this is heated sufficiently by the steam flowing in and, after appropriate comminution, crude salt containing potash reaches the first dissolving drum at a without interruption, it is moved by rotating the drum.
Die Umdrehung der Trommeln, welche zweckmäßig auf Rollen g gelagert sind, geschieht durch Zahnrad- o. dgl. mechanischen Antrieb.The rotation of the drums, which are expediently mounted on rollers g , takes place by means of a gearwheel or similar mechanical drive.
Ist das zuerst einfallende Rohsalz an der ersten Scheidewand E angelangt, so wird es durch die nachfolgenden Mengen durch die Öffnung b geschoben und gelangt in den nächstfolgenden Abteil usw., bis es endlich bei c aus der letzten Trommel durch einen Baggerelevator oder eine andere mechanische Entnahmevorrichtung dem Apparat entführt wird.When the crude salt that falls first has reached the first partition E , it is pushed through the opening b by the subsequent quantities and gets into the next compartment, etc., until it finally comes out of the last drum at c through an excavator elevator or some other mechanical extraction device is kidnapped from the machine.
Die Lauge durchwandert die einzelnen Abteile des Apparates im Gegenstrom zum Rohsalz, reichert sich in demselben nach und nach an und wird bei d als gesättigte Salzlösung ununterbrochen entnommen.The lye travels through the individual compartments of the apparatus in countercurrent to the crude salt, gradually accumulates in the same and is continuously withdrawn at d as a saturated salt solution.
Durch Schwimmerregulierung o. dgl. wird das Laugenniveau in allen Abteilen konstant erhalten.By regulating the float or the like, the lye level in all compartments is constant obtain.
Schwer lösliche Bestandteile des Rohsalzes, wie Kieserit, welche sich beim Lösen von dem körnigen Rückstand trennen, dringen durch die siebartige Lochung der Trommeln, lagern sich auf dem Boden des äußeren Mantels des Apparates, werden durch schmale Schnecken, die auf der Außenseite der Trommeln angebracht sind, getrennt fortbewegt und gelangen durch die Öffnungen e nach der Sammeltasche f, von wo sie dem Apparat entnommen werden.Hardly soluble components of the crude salt, such as kieserite, which separate from the granular residue when they are dissolved, penetrate the sieve-like perforation of the drums, are deposited on the bottom of the outer casing of the apparatus, and are attached by narrow screws on the outside of the drums are moved separately and pass through the openings e to the collection pocket f, from where they are removed from the apparatus.
Im Gegensatz zu bekannten Gegenstromlöseverfahren gestattet das beschriebene bei gleichzeitigem Auslösen der Kalisalze und Abführen des Rückstandes ein Absondern schwerIn contrast to known countercurrent dissolving methods, the one described allows simultaneous release of the potassium salts and removal of the residue difficult to separate

auch gegenüber dem Verfahren der Patentschrift 166187. .soluble ingredients. This difference applies
also compared to the method of patent specification 166187..
