Description

Zur Separierung schlammhaltiger Flüssigkeiten bestimmte Zentrifugalseparatoren, in denen der abgetrennte Schlamm durch Kanäle strömt oder an den Trommelwänden gleitet, sind gewöhnlich infolge der abnutzenden oder schleifenden Wirkung des Schlammes starkem Verschleiß ausgesetzt. Zwar kann der Verschleiß durch besondere Maßnahmen in zulässigen Grenzen gehalten werden; so hat man z. B. die dem Verschleiß besonders ausgesetztenCentrifugal separators designed to separate sludge-containing liquids, in which the separated Sludge flowing through channels or sliding on the drum walls is usually a result exposed to the abrasive or abrasive effects of the mud. Though the wear can be kept within permissible limits by special measures; so one has z. B. those particularly exposed to wear

ίο Flächen mit einem Schutzbelag aus Gummi o. dgl. versehen. Derartige Konstruktionen sind aber in der Regel sehr kostspielig.ίο Areas with a protective covering made of rubber or the like. Mistake. However, such constructions are usually very expensive.

Die Erfindung betrifft einen Zentrifugalseparator zur Separierung von hauptsächlich solchen schlamm-The invention relates to a centrifugal separator for separating mainly such sludge

»5 haltigen Flüssigkeiten, die Schlamm mit stark abnutzender Wirkung enthalten, wobei der abgetrennte Schlamm während der Separierung kontinuierlich oder intermittierend durch in der Trommelwand vorgesehene Schlammabläufe aus der Separator-»5 containing liquids, the mud with heavy wear and tear Effect included, the separated sludge continuously during the separation or intermittently through sludge drains provided in the drum wall from the separator

ao trommel herausgeleitet wird. Bei dem erfindungsgemäßen Zentrifugalseparator werden die obenerwähnten Nachteile grundsätzlich dadurch beseitigt, daß die Separatortrommel an den der Abnutzung besonders ausgesetzten Stellen ihrer Innen-ao drum is led out. In the inventive Centrifugal separator, the above-mentioned disadvantages are basically eliminated by that the separator drum in the areas of its inner drum that are particularly exposed to wear

»5 wand mit Aussparungen, Vertiefungen, Taschen o. dgl. versehen ist, die so ausgebildet sind, daß sie sich während der Separierung mit Schlamm füllen, der dadurch einen örtlichen Verschleiß der Trommel verhindert.»5 wall is provided with recesses, depressions, pockets or the like, which are designed so that they fill with sludge during the separation, which causes local wear of the drum prevented.

Die Erfindung wird in der Zeichnung in Abb. ι im senkrechten Schnitt und in Abb. 2 im Horizontalschnitt durch einen Teil der Wand einer Separatortrommel veranschaulicht.The invention is shown in the drawing in Fig. Ι in vertical section and in Fig. 2 in horizontal section illustrated by part of the wall of a separator drum.

Wie in Abb. ι gezeigt, ist die Trommelwand ι mit einer Anzahl ringförmiger, beispielsweise durch Wegdrehen einer entsprechenden Materialmenge gebildeter "Nuten 2 versehen. Die Nuten sind in der Abbildung stufenförmig angeordnet und dienen zum Festhalten ausseparierten Schlammes während der Separierung, so daß dieser einen schützenden Belag an der Trommelwand bilden kann. Die von den Stufen gebildete Treppe muß eine derartige Neigung l>esitzen, daß der in der Abbildung mit β bezeichnete Winkel kleiner als der mit α bezeichnete sogenannte Schüttwinkel des Schlammes wird. Hierdurch bleibt die mit Nuten versehene Wand während der Separierung völlig mit einer ruhenden Schlammschicht überdeckt, auf welcher der abgetrennte Schlamm in der durch Pfeil 3 angedeuteten Richtung gegen die in Vertiefungen 4 in der Trommelwand vorgesehenen Schlammabläufe 5 hin gleitet. Es ist natürlich nicht notwendig, daß die Nuten, wie es die Abbildung zeigt, stufenförmig längs einer geraden Linie angeordnet sind. Die Anzahl der Nuten kann ebenso wie ihre Tiefe und Breite im übrigen je nach den Umständen schwanken.As shown in Fig. Ι, the drum wall ι is provided with a number of ring-shaped, for example, formed by turning away a corresponding amount of material "grooves 2. The grooves are arranged in steps in the figure and are used to hold the separated sludge during the separation, so that this one The staircase formed by the steps must be inclined so that the angle marked with β in the figure becomes smaller than the so-called angle of repose of the sludge marked with α completely covered with a static layer of sludge during the separation, on which the separated sludge slides in the direction indicated by arrow 3 against the sludge drains 5 provided in depressions 4 in the drum wall shows are arranged in a stepped manner along a straight line. The number of grooves as well as their depth and width can also vary depending on the circumstances.

Der Schlammablauf ist gemäß Abb. 2 mit einem tangential gerichteten Mundstück versehen, das aus einer äußeren, in die Trommelwand 1 eingeschraubten Hülse 6, einer Lochscheibe 7 und einem Rohr 8 besteht. Zwischen der Hülse 6 und der Trommelwand ι ist eine Packung 9 vorgesehen. Das zweckmäßig in einem gegen Abnutzung widerstandsfähigen Material, beispielsweise Glas, ausgeführte und leicht austauschbare Rohr 8 mündet derart in die Vertiefung 4, daß es mit seinem Ende in Richtung gegen das Trommel innere hin frei hervorragt. Während der Separierung bildet sich in der Vertiefung 4 ein Schlammbelag, der das Material der Wand ι und teilweise auch die Hülse 6 gegen Verschleiß schützt. Die beiden Einsatzteile 7 und 8 schützen den Kanal in der Hülse 6 gegen Abnutzung. The sludge drain is provided with a tangentially directed mouthpiece as shown in Fig. 2, which consists of an outer sleeve 6 screwed into the drum wall 1, a perforated disk 7 and a tube 8 consists. A pack 9 is provided between the sleeve 6 and the drum wall 1. That functional made of a material resistant to wear, for example glass and easily exchangeable tube 8 opens into the recess 4 in such a way that it has its end in the direction protrudes freely towards the inside of the drum. Forms in the depression during separation 4 a sludge coating, which the material of the wall ι and partially also the sleeve 6 against wear protects. The two insert parts 7 and 8 protect the channel in the sleeve 6 against wear.
