Description
DEUTSCHESGERMAN
Beim Trennen von Gemischen fester Teilchen mit unterschiedlicher Wichte in einem Hydrozyklon ist es zum Erzielen einer guten Trennung erforderlich, daß das Gemisch zusammen mit der Trenntrübe unter konstantem Druck in den Hydrozyklon eingeleitet wird. Man verwendet hierzu eine Vorrichtung zum Mischen von festen Teilchen mit einer im Kreislauf geführten Trübe, die aus einem mit der Trübe im freien Fall gespeisten Gefäß mit einer Uberlaufkante und einem unteren Ablauf für das Gemisch besteht.When separating mixtures of solid particles of different density in a hydrocyclone it is in order to achieve a good separation it is necessary that the mixture together with the separation beet under constant Pressure is introduced into the hydrocyclone. A device for mixing is used for this purpose of solid particles with a circulating turbidity, which from one with the turbidity in free fall fed vessel with an overflow edge and a lower outlet for the mixture.
Diese Vorrichtung hat den Nachteil, daß Teilchen des Gemisches, die eine niedrigere Wichte haben als die Trenntriibe, die Neigung aufweisen, auf der in dem Gefäß vorhandenen Trübe zu schwimmen, so daß sie zusammen mit der über die Überlauf kante abfließenden Trübe abgeführt werden, worauf sie von der Umlaufpumpe rezirküliert werden; Dies verursacht einen zusätzlichen Verschleiß der Pumpe. Weiterhin findet eine Grusbildung der mit der Trübe rezirkulierten leichten Teilchen statt, wodurch sich der Verkauf swert dieses Produkts herabsetzt und, indem sich die Viskosität der Trenntriibe durch diese zerkleinerten leichten Teilchen steigert, die Trennschärfe der im Hydrozyklon erzielten Trennung beeinträchtigt wird. Auch in dem Fall, daß das Gefäß so dimensioniert ist, daß die Geschwindigkeit der Trübe größer ist als die Aufwärtsgeschwindigkeit der in"der Trübe" vorhandenen leichten Teilchen, findet ein Aufsteigen der leichten Teilchen an den Gefäßwänden entlang, wo die Geschwindigkeit der Trübe gering ist, statt, wodurch leichte Teilchen in den Überlauf hineingeraten.This device has the disadvantage that particles of the mixture that have a lower specific gravity than the separation ribs, which tend to float on the turbidity present in the vessel, so that they are discharged together with the sludge flowing over the overflow edge, whereupon they are removed from the circulation pump are recirculated; This causes additional wear on the pump. Farther the light particles recirculated with the sludge form gravel, which leads to increased sales The value of this product is reduced and the viscosity of the separating belts is reduced by them light particles increases, the selectivity of the separation achieved in the hydrocyclone is impaired will. Even in the event that the vessel is dimensioned so that the speed of the pulp is greater is than the upward speed of the light particles present in "the pulp", an upward movement takes place of the light particles along the vessel walls, where the velocity of the pulp is slow, which means light particles got into the overflow.
Die Erfindung betrifft eine Vorrichtung, die die obenerwähnten Nachteile nicht aufweist. Bei dieser Vorrichtung weist erfindungsgemäß auch der die Überlaufkante enthaltende Gefäßteil eine öffnung für das Einleiten der Trübe im freien Fall auf, und dieser Gefäßteil ist mit dem anderen Teil über einen Spalt verbunden.The invention relates to a device which does not have the disadvantages mentioned above. At this According to the invention, the device also has an opening for the vessel part containing the overflow edge introducing the slurry in free fall, and this part of the vessel is with the other part via a gap tied together.
Die Geschwindigkeit der Trübe in dem Verbindungsspalt kann nunmehr erheblich höher sein als die Aufwärtsgeschwindigkeit der leichten Teilchen, ohne daß der eigentliche Mischraum verengert zu werden braucht. Durch Anwendung einer spaltförmigen öffnung wird eine geräumige Verbindung zwischen dem die Überlaufkante enthaltenden Gefäßteil und dem anderen Teil erzielt, während doch die entlang des Randes dieses Spaltes gelegene Zone, in der die Trübe eine Geschwindigkeit hat, die niedriger ist als die mittlere Geschwindigkeit innerhalb des Spaltes, sehr schmal ist.The speed of the pulp in the connecting gap can now be considerably higher than that Upward speed of the light particles without the actual mixing space being restricted needs. By using a gap-shaped opening, a spacious connection between the the overflow edge containing the vessel part and the other part achieved, while the along the At the edge of this gap, in which the slurry has a velocity which is lower than that medium speed within the gap, is very narrow.
Wenn in dem Spalt ein verstellbarer Ventilkörper angeordnet ist zum Regeln der Ventilbreite, kann die Mischvorrichtung leicht den Umständen wie Korngröße und Wichte des zu trennenden Materials undIf an adjustable valve body is arranged in the gap to regulate the valve width, the Mixing device easily the circumstances such as grain size and weight of the material to be separated and
