Description

Verfahren zum Entwässern von aus dem Schaumschwimmverfahren stammenden Schlämmen. Die Erfindung betrifft ein Verfahren zum Entwässern von aus dem Schaumschwiminverfahren stammenden Schlämmen und besteht darin, daß der Schaumschlamm auf eine grobkörnige Filterschicht an sich bekannter Art aufgegeben und die Filterschicht in eine schüttelnde Bewegung versetzt wird. Infolge der schüttelnden Bewegung der Entwässerungsflächen und der saugenden Wirkung des aus der Filterschicht abziehenden Wassers erfolgt eine Zerstörung des Schaums und dadurch eine weitgehende Entwässerung des Schlammes. Diese Wirkung wird unterstützt durch die beim Schütteln des Siebes erfolgte Umordnung der feinen und groben Gutsteile, welch letztere nach oben zu gelangen suchen und dabei durch Eindringen in die Blasen den Schaum zerstören. Es ist an sich bekannt, beim Entwässern von Mineralschlämmen eine grobkörnige Filterschicht zu verwenden. Ebenso ist es an sich bekannt, feinkörnige bis schlämmigeProdukte dadurch zu entwässern, daß man sie über eine feinmaschige, schüttelnd bewegte Siebfläche leitet. Die Erfindung besteht in der Vereinigung der beiden Merkmale und in der Verwendung für Schlämme aus dem Schaumschwimmverfahren, wodurch die obenerwähnten Vorteile erreicht werden. Als Filterschicht wird man zum Entwässern von Erzschlämmen zweckmäßig eine grobkörnigere Erzschicht und beim Entwässern von Kohlenschlämmen Kohle aus der Kohlenwäsche, z. B. Kokskohle, verwenden. Die festen Bestandteile der Schlämme werden zusammen mit den körnigen Filterschichtteilchen gemischt am Ende der Entwässerungsfläche ausgetragen. Man hat es in der Hand, durch die Wahl des Filtergutes eine beabsichtigte Mischung von Filtergut und Schlämmeteilchen zu erhalten. Zur Begünstigung der Entwässerung kann man unter der Entwässerungsfläche ein Vakuum erzeugen.Process for dewatering originating from the foam floating process Sludge. The invention relates to a method for dewatering from the foam swimming process originating sludge and consists in the fact that the foamed sludge on a coarse-grained Abandoned filter layer of a known type and the filter layer in a shaking Movement is displaced. As a result of the shaking movement of the drainage surfaces and the sucking effect of the water drawn off from the filter layer takes place destruction of the foam and thus extensive dewatering of the sludge. This effect is supported by the rearrangement that takes place when the sieve is shaken the fine and coarse good parts, which the latter seek to reach the top and destroy the foam by penetrating the bubbles. It is known per se to use a coarse-grained filter layer when dewatering mineral sludge. It is also known per se to dewater fine-grained to slurry products by that they are passed over a fine-meshed, shaking sieve surface. The invention consists in the union of the two characteristics and in the use for sludge from the foam swimming process, whereby the advantages mentioned above are achieved. A coarse-grained filter layer is expediently used as a filter layer for dewatering ore sludge Ore layer and when dewatering coal sludge coal from coal washing, z. B. coking coal, use. The solid components of the sludge are together with the granular filter layer particles mixed at the end of the drainage surface. You have it in your hand, through the choice of the filter material, an intended mixture of filter material and sludge particles. To favor drainage you can create a vacuum under the drainage surface.
