Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das Verfahren bezweckt die schnelle Scheidung von Flüssigkeiten von den in ihnen enthaltenen ungelösten Stoffen und die schnelle Gewinnung von Trockengut aus letzteren.
Das Wesentliche des neuen Verfahrens besteht darin, daß ein ununterbrochener Strom von schlammhaltiger Flüssigkeit durch ein aus Filterfiächen gebildetes Gefäß geführt wird, und die Rückstände hier unter gleichzeitiger
The purpose of the process is the rapid separation of liquids from the undissolved substances they contain and the rapid recovery of dry matter from the latter.
The essence of the new process is that an uninterrupted stream of sludge-containing liquid is passed through a vessel formed from filter surfaces, and the residues here under simultaneous

ίο Absaugung der Flüssigkeit durch künstlichen Zug von Luft oder Gasen, die durch die Filterflächen abwechselnd ein- und austreten und diese selbsttätig reinigen, bis zur Trocknung durchströmt werden.ίο Suction of the liquid through artificial Draft of air or gases that alternately enter and exit through the filter surfaces and clean them automatically until the water flows through them until they are dry.

Die Ausführung des neuen Verfahrens kann z. B. mit Hilfe der in der Zeichnung schematisch dargestellten Einrichtung folgendermaßen geschehen: Die schlammhaltige Flüssigkeit tritt bei α in den wagerecht, senkrecht oder geneigt gelagerten Hohlzylinder b, c, d, e in . dessen Innenraum sich eine Förderschnecke befindet. Auf der Strecke f, g, h, i ist der Zylindermantel mit der Schnecke fest verbunden, besteht aus Filtertuch oder Filtermasse und dreht sich also mit der Schnecke, während er zwischen b, f und c, g sowie h, iijund i, e festgelagert ist. Zwischen f, h undg, i ist eine mit dem feststehenden Zylinder fest verbundene kasten- oder röhrenförmige Umkleidung (Trocknungsraum) des umlaufenden Zylinders angeordnet, in welche bei k die Luft oder die Gase einströmen. Infolge der in Fig. 2 dargestellten Dichtungskörper η treten die Gase von außen durch den Filterniantel in den umlaufenden Zylinder und verlassen ihn zugleich mit der abgesaugten Flüssigkeit auf der entgegengesetzten Seite infolge des bei I erzeugten künstlichen Zuges. Die an der Austrittsstelle sich etwa verstopfenden Poren des Filters werden bei seiner Umdrehung durch den Durchtritt der Gase an der k zugekehrten Seite selbsttätig von den angesaugten Schlammteilen gereinigt.The execution of the new method can, for. B. can be done with the help of the device shown schematically in the drawing as follows: The sludge-containing liquid occurs at α in the horizontally, vertically or inclined hollow cylinder b, c, d, e in. the interior of which is a screw conveyor. On the section f, g, h, i , the cylinder jacket is firmly connected to the screw, consists of filter cloth or filter material and thus rotates with the screw while it is fixed between b, f and c, g as well as h, iij and i, e is. Between f, h and g, i there is a box-shaped or tubular casing (drying space) of the rotating cylinder firmly connected to the stationary cylinder, into which the air or the gases flow at k. As a result of the sealing body η shown in FIG. 2, the gases pass from the outside through the filter element into the rotating cylinder and leave it at the same time with the sucked off liquid on the opposite side as a result of the artificial draft generated at I. The pores of the filter, which may become clogged at the outlet point, are automatically cleaned of the sucked-in sludge particles during its rotation by the passage of the gases on the side facing the k.

Das Trockengut wird durch die Schnecke in den feststehenden Zylinderteil h, d, e, i weiterbefördert und verläßt ihn bei m. Die Luft oder die Gase treten entweder unmittelbar bei k ein oder strömen, wenn eine Heizung der Trommel erwünscht ist, bei 0 in die hohle Spindel der Schnecke und werden weiter durch das feststehende Rohr φ, q bei k in den erwähnten Trocknungsraum geleitet.The product to be dried is conveyed by the screw into the stationary cylinder part h, d, e, i and leaves it at m. The air or the gases either enter directly at k or, if heating of the drum is desired, flow into the at 0 hollow spindle of the screw and are passed on through the fixed tube φ, q at k into the mentioned drying room.

Entsprechend dem Grade der Trocknung erweitert sich der Spindeldurchmesser, so daß also die Spindel innerhalb des Trocknungsraumes kegelförmig gestaltet ist. Erforderlichenfalls werden mehrere Trocknungsräume in angemessenen Entfernungen hintereinander angeordnet. Die Schnecke kann durch ein beliebiges anderes Förder- oder auch Druckmittel ersetzt werden oder bei genügender Schräglage der Trommel fortfallen.The spindle diameter expands in accordance with the degree of drying, so that so the spindle is conical within the drying room. If necessary several drying rooms are arranged one behind the other at reasonable distances. The snail can go through a any other conveying or pressure medium can be replaced or if the incline is sufficient fall away from the drum.

Zum Betriebe werden vorteilhaft Abgase verwendet. Die Vorrichtung kann auch mit kleinen Abänderungen als Flüssigkeitsheber nach Art der Wasserschrauben benutzt werden.Exhaust gases are advantageously used for operation. The device can also with small modifications can be used as a liquid siphon in the manner of a water screw.

K Patent-Ansprüche:The filter jacket can also be fixed if the drying room is arranged around the circumference. K patent claims: 1. Verfahren zur Trennung von Flüssig- j keiten von in ihnen enthaltenen ungelösten ι Stoffen unter gleichzeitiger Trocknung letzterer, dadurch gekennzeichnet, daß durch1. Process for separating liquids from undissolved ι contained in them Substances with simultaneous drying of the latter, characterized in that by ίο die ganz oder zum Teil aus Filtermasse bestehenden Wandungen eines Gefäßes, durch welches die die ungelösten Bestandteile enthaltende Flüssigkeit geleitet wird, unter gleichzeitiger Absaugung der abzuscheidenden Flüssigkeit ein Strom von Luft oder Gasen derart geführt wird, daß er die •Rückstände im Gefäß trocknet und dauernd oder zeitweise das Filter reinigt.ίο the walls of a vessel consisting entirely or in part of filter material, through which the liquid containing the undissolved constituents is passed, a stream of air with simultaneous suction of the liquid to be separated or gases is conducted in such a way that it dries the residues in the vessel and lasts or temporarily cleans the filter. 2.
