Die aus den Kohlenwäschen abfließenden Waschwässer enthalten außer den Bergen, die durch ihre Schwere ausscheiden, größere Mengen Feinkohle, deren Trennung yon den im Wasser enthaltenen sehr feinen Schlämmen bisher praktisch nicht gelungen ist. Man läßt bisher diese Wässer in Klärbecken laufen, wo sich Feinkohle und Schlämme setzen und die sogenannte Schlammkohle bilden.The washing water flowing out of the coal washers contains, in addition to the mountains, the due to their gravity, large quantities of fine coal are separated, which are separated from the im Very fine sludge contained in water has so far been practically unsuccessful. One lets So far, these waters run in clarifiers, where fine coal and sludge settle and the form so-called sludge coal.
ίο Die Erfindung betrifft nun ein Verfahren zum Scheiden der in den Waschwässern der Kohlenwäschen enthaltenen Feinkohle von den Schlämmen. Das Verfahren bedient sich zur Ausscheidung der Feinkohle eines Siebes. Durch das übliche Abscheiden mit Hilfe eines Siebes, dessen Maschen kleiner sind, als die auszuscheidenden Kohleteilchen, würde man im vorliegenden Falle aber nicht zum Ziele kommen, da die Kohleteilchen. sich auf dem Sieb festsetzen und in ganz kurzer Zeit die Maschen des Siebes verstopfen würden, so daß das Sieb unwirksam wird.The invention now relates to a method for separating the fine coal contained in the washing water of the coal washes from the Sludge. The process uses a sieve to separate the fine coal. By the usual separation with the help of a sieve whose meshes are smaller than those to be separated Coal particles, one would not reach the goal in the present case, because the coal particles. settle on the sieve and in a very short time the meshes of the sieve would clog, so that the sieve becomes ineffective.
Die Erfindung wendet nun ein Sieb an, dessen Maschen größer sind als die auszuscheidenden Kohleteilchen, und verhindert das Hindurchtreten der Kohleteilchen zusammen mit dem Wasser und dem Schlamm dadurch, daß das als Trommel ausgebildete Sieb in schnelle Rotation versetzt wird. Hierbei wird das Wasser mit den sehr feinen Schlämmen von außen nach innen durch das Sieb hindurchgesaugt, während durch die schnelle Rotation des Trommelsiebes die an dasselbe anstoßenden Kohleteilchen aus dem Bereich der Saugwirkung herausgeschleudert werden. Diese abgeschiedenenThe invention now uses a sieve whose meshes are larger than those to be separated Coal particles, and prevents the passage of the coal particles together with the Water and the sludge in that the sieve, which is designed as a drum, rotates rapidly is moved. Here, the water with the very fine sludge is turned from the outside sucked through the inside of the sieve, while by the rapid rotation of the drum screen the coal particles adjoining the same are thrown out of the area of the suction effect will. These secluded
Kohleteilchen werden z. B. durch ein Becherwerk abgeführt. Damit das Trommelsieb bei seiner Arbeit ständig reingehalten wird, wird es so angeordnet, daß es nur teilweise in das Wasser eintaucht, so daß die Siebwandung beim Heraustreten aus dem Wasser gespült wird.Coal particles are z. B. discharged through a bucket elevator. So that the drum screen at its work is constantly kept clean, it is arranged so that it is only partially in the Water is immersed so that the sieve wall is rinsed when stepping out of the water will.
Auf der Zeichnung ist eine zur Ausübung des Verfahrens geeignete Vorrichtung schematisch dargestellt.A device suitable for carrying out the method is shown schematically in the drawing shown.
Das von der Kohlenwäsche kommende Waschwasser tritt bei 1 in einen Behälter ein und stößt gegen eingebaute Wände 2, 3, 4, 5. Unter dem Trommelsieb b, welches durch die Wände 2> 3> A> 5 gegen das unmittelbare Auftreffen des Wassers auf die Siebwandung geschützt ist, ist ein Flügelrad i angeordnet, das die Kohleteilchen, die auf der linken Seite an die Wände 2, 3, 4, 5 anstoßen und heruntersinken, einem Becherwerk f, g zuschiebt und oben die Kohleteilchen, die noch nicht herabgesunken sind, gegen die rechte Seite der Trennungswände 2> 3. 4) 5 wirft, an denen sie wieder heruntersinken. Eine seitlich unterhalb des Trommelsiebes b angeordnete Wand 6 bewirkt, daß das Gemisch von der rechten Seite nicht unmittelbar auf die Siebtrommel gelangen kann, sondern erst absinkt, ehe es zum Abfluß auf die Trommel b gelangt.The light coming from the coal washing washing water enters a tank at 1 and abuts against built-walls 2, 3, 4, 5. b Under the drum screen comprising 5 g by the walls 2> 3>A> e g s the direct impingement of the Water on the sieve wall is protected, an impeller i is arranged, which pushes the coal particles that hit the left side of the walls 2, 3, 4, 5 and sink down to a bucket elevator f, g and above the coal particles that have not yet have fallen down against the right side of the partition walls 2 > 3. 4) 5 throws, where they sink down again. A wall 6 arranged laterally below the drum screen b has the effect that the mixture cannot reach the screen drum directly from the right side, but only sinks before it reaches the drain on drum b .
Die Trommel b besitzt einen Siebmantel, dessen Maschen weiter sind als die auszuscheidenden Kohleteilchen. Durch die hohle Achse der Trommel wird das Wasser abgesaugt. Die Trommel wird in so schnelle Rotation versetzt, daß die auf dieselbe auftreffenden Kohle-The drum b has a sieve jacket, the meshes of which are wider than the coal particles to be separated out. The water is sucked off through the hollow axis of the drum. The drum is set in rotation so fast that the coal
teilchen aus dem Bereich der Saugwirkung herausgeschleudert werden und daher nur das Wasser mit den sehr feinen Schlämmen durch die Trommel hindurch abgesaugt wird. Die ausgeschiedenen Kohleteilchen werden durch das Becherwerk f, g abgeführt. Da die Trommel b nur bis zur Hälfte in das Wasser eintaucht, so wird die Siebwandung derselben beim Austauchen aus dem Wasser dauernd gespült, so daß eine Verstopfung der Siebmaschen mit Sicherheit vermieden wird.Particles are thrown out of the area of the suction effect and therefore only the water with the very fine sludge is sucked through the drum. The separated coal particles are discharged through the bucket elevator f, g. Since the drum b is only half immersed in the water, the sieve wall of the same is continuously rinsed when it emerges from the water, so that clogging of the sieve meshes is avoided with certainty.
