Schneckenflügel in Form einer Spirale befestigt sind.Screw blades are attached in the form of a spiral.

Patentiert im Deutschen Reiche vom 10. Oktober 1911 ab.Patented in the German Empire on October 10, 1911.

Die Vorrichtung besteht aus einem Trog von beliebiger Länge mit einer rotierenden Welle 5.The device consists of a trough of any length with a rotating shaft 5.

Auf dieser sind schöpfbecherartig ausgebildete Schneckenflügel c spiralig angeordnet befestigt. Die dem wandernden Lösegut zugewandte Seite d (Fig. 4) des Bechers c ist voll gehalten. Die entgegengesetzte Seite e (Fig. 4) ist dagegen teilweise oder ganz ausgespart, damit das durch die rotierenden Becher gehobene Salz in der Transportrichtung des Lösegutes hinausfallen kann, um dann von dem nächsten Becher gefaßt und so der 'Löseflüssigkeit entgegen befördert zu werden.On this scoop-like formed screw blades c are attached spirally arranged. The side d (Fig. 4) of the cup c facing the moving material to be dissolved is kept full. The opposite side e (Fig. 4), on the other hand, is partially or completely recessed so that the salt lifted by the rotating beaker can fall out in the direction of transport of the material to be dissolved, in order to then be taken by the next beaker and thus conveyed against the 'dissolving liquid.

Um das Hinausfallen des Lösegutes zu erleichtern, fällt der Boden des Bechers von der geschlossenen Seite d nach der offenen Seite β hin geneigt ab.In order to facilitate the falling out of the material to be dissolved, the bottom of the beaker slopes down from the closed side d to the open side β .

Zur eventuellen Unterteilung des vorliegenden Schneckentroges können Scheidewände beliebiger Konstruktion verwendet werden.Any partition walls can be used for the eventual subdivision of the present snail trough Construction can be used.

Verwendet man rotierende Scheidewandscheiben, also solche, die auf der Welle mit befestigt sind und die sich mit der Welle drehen, so werden diese Scheiben mit Öffnungen versehen, welche das Lösegut und die Löseflüssigkeit hindurchlassen. If you use rotating partition disks, i.e. those that are attached to the shaft and which rotate with the shaft, these disks are provided with openings, which allow the solvent and the solvent to pass through.

An den rotierenden Scheidewandscheiben werden dann vor die Öffnungen die oben beschriebenen Schöpfbecherflügel in der Weise befestigt, daß das aus der offenen Seite des Bechers herausfallende Lösegut durch die Öffnung der Scheidewandscheiben in die nächste Abteilung fällt.The openings described above are then placed on the rotating septum disks in front of the openings Scoop wings attached in such a way that the falling out of the open side of the cup Soluble material falls through the opening in the partition into the next compartment.

Diese Anordnung mit rotierenden Scheiben läßt sich noch mit feststehenden Scheidewänden kombinieren, und zwar derart, daß im Troge vor diesen feststehenden Scheidewänden die oben beschriebene, auf der Welle befestigte, mit Bechern und Löchern versehene Scheidewand rotiert. In der feststehenden Scheidewand sind in der gleichen Höhe wie bei der rotierenden Scheidewand gleichfalls Öffnungen angebracht. Es schließt also die rotierende und die feststehende Scheidewand die Abteilung des Troges ab, und erst in dem Moment, wo sich die Öffnungen der festen und rotierenden Scheidewand decken, kann das Lösegut und die Löseflüssigkeit in die andere Abteilung übertreten.This arrangement with rotating disks can still be used with fixed partitions combine, in such a way that in the trough in front of these fixed partitions the septum described above, attached to the shaft and provided with cups and holes rotates. In the fixed septum are at the same height as in the rotating one Separation wall also made openings. So it includes the rotating and the fixed Partition walled off the compartment of the trough, and only at the moment when the openings cover the fixed and rotating septum, the solvent and the solvent can be move to the other department.

Je nachdem man die Löcher auf dem Umfang der feststehenden Scheidewand anordnet, kann die Lösung ganz nach Belieben zwangläufig ge- 50' führt werden.Depending on how the holes are arranged on the circumference of the fixed partition, can the solution can inevitably be carried out entirely at will.

Es bedingt dieses aber wieder eine Form des Bechers, die dem an einer gewünschten Stelle im Trog gewählten Durchgang angepaßt sein muß. Würde man die gewöhnliche Ausführung des Bechers wählen, so könnte der Fall eintreten, daß das Lösegut schon vorher in den Trog zurückgefallen wäre, ohne daß es durch die Öffnungen der Scheidewände hindurchtransportiert worden wäre..However, this again requires a shape of the cup that can be placed in a desired location must be adapted to the passage selected in the trough. One would do the ordinary run of the cup, it could happen that the ransom was already in the The trough would have fallen back without it being transported through the openings in the partition walls would have been ..

Dies würde besonders da eintreten, wo die Becher erst auswerfen sollen, wenn sie den höchsten Punkt schon erreicht haben, also gewissermaßen unter sich auswerfen sollen. Man muß für diesen Fall die Becher noch mit einem Deckel versehen, gegen den sich das LösegutThis would occur especially where the cups should only eject when they have have already reached the highest point, so to speak, should throw out among themselves. Man In this case, the cup must also be provided with a lid against which the material to be dissolved

Claims

can place, and who gets such an inclination against the rotating partition that the material to be dissolved can slide out through the opening of the fixed partition. In the event that less soluble material is to be processed or the dissolving trough has to be relatively short, care must be taken that the salt falling out of the scoop wings in the transport direction of the dissolving material falls out in the thinnest and broadest possible litter and surface. For this purpose, a rib or an elevation f (Fig. Ι and 4) can be attached in the cup, which runs diagonally from the lower corner of the cup in the transport direction of the material to be dissolved to its center and runs out there. (When speaking of the upper and lower side of the beaker, the side attached to the shaft is the lower.) If the rotating beaker now picks up the material to be dissolved from the bottom of the screw trough, only about part of the material falls due to the presence of the elevation f The material to be released from the cup over the open side e (Fig. 4) of the cup in the direction of transport, while the other half falls over g and the shaft b straight down again without being transported forward. Depending on the shape of the outlet g, it can even be achieved to let this part of the good fall back quite considerably, so that even the cup that had previously done the loosening work has to lift this good again. As a result of the further expansion of the contents of the cup, the dissolving eye can approach the material better, and the dissolving is faster, easier and takes place in a smaller space or less mixing of the solute, also depending on the loosening material itself, the length of the trough • 45 and the desired inevitability of the lye flow. Fig. 2, 3 and 5 show the displacement of the shaft, the mounting of the bearings and the position of two rotating partition disks 4 shows the fastening of the individual cups on a square shaft. The hubs are manufactured in such a way that they can be screwed over the shaft and that one cup always holds the other. , Sludge leaching, washing, mashing and mixing apparatus can be used All other known constructions insofar as the length of the trough makes it very easy to subdivide the alkalis within the trough into concentration levels, and the heat adhering to the residue can be removed much further than was possible with the shorter dissolving devices previously used . Sponsorship τ claims:

Device for dissolving crude potash salts and other bodies and removing them of the dissolving residues in countercurrent to the dissolving liquid, in which screw blades in the form of a spiral are mounted on a shaft are attached, characterized in that these screw blades are designed as cups are, in such a way that they can be used both as a transport cup and as a litter and ■ Distribution device act, and the after The side wall facing the direction of transport of the loosened material is completely or partially cut out is.
