Description

Zum Lösen von feinkörnigen Stoffen dienender Behälter.Container for loosening fine-grained materials.

Zum Lösen feinkörniger Stoffe benutzt man u. a. auch Behälter mit über der Bodenmitte senkrecht angeordneter hohler Welle und einer im oberen Teile befindlichen Vorrichtung zum Verteilen des durch die Hohlwelle gehobenen Lösegutes. For loosening fine-grained substances one uses, among other things. also container with A hollow shaft arranged vertically above the bottom center and one in the upper part located device for distributing the loosened material lifted by the hollow shaft.

Bei manchen Stoffen wird der Lösevorgang dadurch gehemmt, daß sich die körnigen Feststoffe mit einer Haut aus schlammfeiner Masse überziehen und dadurch dem Angriff des Lösemittels entzogen werden. Dies ist besonders dann der Fall, wenn das Lösegut einen Tongehalt hat und dieser über 25 Prozent des Lösemittels ausmacht. With some substances the dissolving process is inhibited by the fact that cover the granular solids with a skin of fine mud and thereby removed from attack by the solvent. This is especially the case when the solute has a clay content and this makes up more than 25 percent of the solvent.

Um diesen Übelstand zu beseitigen, werden nach der Erfindung am unteren Ende der Hohlwelle an sich bekannte, an Rührarmen befestigte Arbeitsschaufeln und daneben Heizvorrichtungen, z. B. eine Heizschlange, in dem Behälter in an sich bekannter Weise vorgesehen. Diese beschaufelten Rührarme nehmen das Gut immer wieder vom flachen Boden auf, schaufeln es fort und zerreiben dabei die um die einzelnen Körner entstandene Haut, so daß das Gut unausgesetzt der Wirkung des Lösemittels unterliegt. Dieser Erfolg wird wesentlich dadurch beschleunigt, daß man das Gemisch unter erhöhter Temperatur hält. In order to eliminate this drawback, according to the invention at the bottom End of the hollow shaft known per se, attached to agitator arms and working blades in addition heating devices, e.g. B. a heating coil, in the container in per se known Way provided. These shoveled agitator arms take the product from the flat again and again Soil up, shovel it away and grind up what has arisen around the individual grains Skin, so that the material is continuously exposed to the action of the solvent. This Success is significantly accelerated by the fact that the mixture under increased Temperature.

Die neue Vorrichtung ist beispielsweise in der Abbildung im Schnitt dargestellt. The new device is shown in section, for example shown.

In einem Behälter a ist eine hohle Welle b vorgesehen, die von oben her in beliebiger Weise angetrieben wird. In die Welle wird mittels des Zuleitungsrohres c Preßluft eingeführt. Die Welle trägt oben eine Verteilervorrichtung d und ist unten mit radialen Armen e versehen, an denen die Schaufeln sitzen. Sobald das Lösegut in den Behälter eingeführt ist, sinkt es naturgemäß durch das Lösungsmittel hindurch dem Boden zu, wird hier durch die rotierenden Schaufeln energisch durchgearbeitet, gleichzeitig nach der Mitte des Behälters hin bewegt, sodann innerhalb der hohlen Welle b mittels der durch Rohr c zugeführten Preßluft emporgehoben und durch die Vefteilervorrichtung in den Mischbehälter zurückgebracht. Hierbei wird, wie schon oben erwähnt, die Ablösung der die einzelnen Teilchen des Lösegutes umhüllenden Haut durch die mit Schaufeln versehenen Rührarme bewirkt. In a container a, a hollow shaft b is provided from above is driven forth in any way. In the shaft is by means of the supply pipe c Compressed air introduced. The shaft carries a distributor device d and is at the top Provided at the bottom with radial arms e on which the blades sit. As soon as the ransom is inserted into the container, it naturally sinks through the solvent towards the ground, is vigorously worked through here by the rotating shovels, at the same time moved towards the center of the container, then within the hollow Shaft b lifted up by means of the compressed air supplied through tube c and through the Distribution device returned to the mixing tank. Here is how already mentioned above, the detachment of the enveloping the individual particles of the solute Skin caused by the paddled paddle arms.

Diese ablösende Wirkung wird durch die Erwärmung des Behälterinhaltes mittels der Heizspirale s noch erhöht. This releasing effect is caused by the heating of the contents of the container increased by means of the heating coil s.
