Vorrichtung zur kontinuierlichen Verstellung von filtrattrennzonen am Steuerorgan τοη Drehfiltern.Device for the continuous adjustment of filtrate separation zones on the control unit τοη rotary filters.

Die Erfindung betrifft eine Torrichtung zur kontinuierlichen Verstellung von IPiI trat tr ennz onen am Steuerorgan von Brehfiltern. The invention relates to a gate direction for continuous Adjustment of IPiI occurred sepa ration zones on the control organ of brewing filters.

Bei dem Betrieb von Drehfiltern tritt sehr oft die Notwendigkeit auf, ein Trübfiltrat, das jedesmal entsteht, wenn die Zelle in die zu filtrierende Suspension eintaucht und noch nicht mit Kuchen "bedeckt ist, von dem nachfolgenden Klarfiltrat zu trennen, das eintritt, sobald sich auf der lilterflache ein Kuchen gebildet hat und dieser die filtration übernimmt. Weiterhin muß sehr oft die Trennung einer Mutterlauge von einer verdünnten Waschlauge durchgeführt werden. Man kann im Versuch die genaue Lage dieser Trennung nicht bestimmen, weil für ihre Lage am großen Jilter das Verhältnis von !Filteroberfläche zum Volumen der Zelle und der Rohrleitungen eine Rolle spielt. Dieses in der Praxis vorliegende Verhältnis läßt sich schlecht im Versuch genau einhalten. Aus diesem Grunde sind schon Vorschläge für die Einstellung der Trehnzone am Betriebsfilter während des Betriebes gemacht worden. Man hat aus dem Steuerorgan in dem Bereich, in dem die Eiltrattrennung' erfolgen muß, eine Reihe von Rohrleitungen herausgeführt. Diese Rohrleitungen münden in einem Zylinder und durch Verschieben eines Kolbens in diesem Zylinder kann man die aus den Rohrleitungen heraustretende !Flüssigkeit entweder zum Mutterfiltrat oder zum Waschfiltrat führen. Diese Anordnung erlaubt keine stüfenlose Verschiebung der Trennstelle, weil 'jnan nur von Rohr zum Rohr trennen kann. Weiherhin ist es recht kompliziert, diese Rohrleitungen aus dem Steuerorgan herauszuführen, wenn man einerseits eine Trübfiltrattrennung und andererseits eine Trennung in Mutter- und Waschlauge durchführen will, weil die Rohrleitungen doch ziemlich viel Platz in Anspruch nehmen.In the operation of rotary filters, the need arises very often, a cloudy filtrate, which occurs every time the Cell immersed in the suspension to be filtered and still not covered with cake "is to be separated from the subsequent clear filtrate, which occurs as soon as it is on the filter surface a cake has formed and this takes over the filtration. Furthermore, a mother liquor has to be separated very often can be carried out using a dilute wash liquor. One cannot determine the exact position of this separation in the experiment, because for their location on the large filter the ratio of! filter surface to the volume of the cell and the piping plays a role. This relationship present in practice leaves badly sticking to the attempt exactly. For this reason, suggestions for setting the Trehnzone are already on Operation filter has been made during operation. One has A number of pipelines are led out of the control unit in the area in which the rapid separation must take place. These Pipelines open into a cylinder and by moving a piston in this cylinder you can remove them from the pipelines escaping! liquid either to the mother filtrate or lead to the wash filtrate. This arrangement does not allow seamless displacement of the separation point because 'jnan only from pipe can separate to the pipe. Weiherhin it is quite complicated to lead these pipelines out of the control element, if you want to carry out on the one hand a Filtrate separation and on the other hand a separation into mother liquor and wash liquor, because the Pipelines take up a lot of space.

Die Erfindung sieht deshalb vor, ein kontinuierlich verstellbares Trennelement im Steuerorgan selbst anzubringen undThe invention therefore provides a continuously adjustable To attach separating element in the control element itself and

nicht, wie bisher bekannt, aus im Steuerorgan festgelegten Zonen Rohrleitungen herauszuführen und dann in einem Sammelrohr durch Verschiebung eines Kolbens die Flüssigkeit entweder zu dem Ableitungsrohr zu leiten, das aus der Mutterfiltratzone, oder zu dem, das aus der Waschfiltratzone kommt.not, as previously known, from those specified in the control organ Zones lead out pipelines and then either the liquid in a collecting pipe by moving a piston to the discharge pipe coming from the mother filtrate zone or to that coming from the wash filtrate zone.

Die Abbildung 1 zeigt den Querschnitt eines Drehfilters. Es stellt 1 die Filtertrommel, 2 den Filtertrog dar. Die Trennwände 3 teilen die Irommeloberfläche in die Zellen 4· Von diesen Zellen 4 laufen Filtratabführungsrohre 5 zur Nabe 6. Bei einem Ringsteuerkopf biegen diese Piltratabführungsröhre im Steuerkern 7 an der Peripherie und bilden dort den Lochkranz 8. Dieser Lochkranz wird überdeckt durch den feststehenden Steuerring 9. In diesem Steuerring 9 sind normalerweise die feststehenden Stopfen 11 und 12 angebracht, die den IiI-tervorgang in die Filterzone 13? die Wasch- und Troekensaugzone 14 und die Abnahmezone 15 unterteilen. Wenn man die Trennung von Filtrat und Waschwasser durchführen will, muß man den Stopfen 12 betrachten. In der Kammer 13 wird die Mutterlauge gesammelt und abgeführt und in der Kammer 14 die Waschlauge. Soll die Trennung verschoben werden, so muß dieser Trennstopfen entweder in Richtung zum Stopfen 10 oder zum Stopfen 11 bewegt werden. Erfindungsgemäß wird vorgeschlagen, diesen Stopfen 12 in ein Formstück 16 einzubauen, damit er in dem Kanal des Steuerringes 9 dadurch verschoben werden kann, daß in einer an dem Formstück angebrachten Zahnplatte 17 eine Zahnstange 18 eingreift, die vermittels der Spindel 19 bewegt werden kann. Auf diese Weise ist es möglich, stufenlos die Veränderung der lage der Trennzone vorzunehmen.Figure 1 shows the cross section of a rotary filter. It 1 shows the filter drum, 2 the filter trough. The partition walls 3 divide the Irommel surface into the cells 4 · Von Filtrate discharge pipes 5 run from these cells 4 to the hub 6. In the case of a ring control head, these piltrate evacuation tube bend in the control core 7 at the periphery and form the perforated ring 8 there. This perforated ring is covered by the stationary one Control ring 9. In this control ring 9 are normally the fixed plugs 11 and 12 attached, which the IiI-tervorgang in the filter zone 13? the wash and dry suction zone 14 and subdivide the decrease zone 15. If you want to separate the filtrate and wash water, you have to look at the plug 12. In the chamber 13 is the mother liquor collected and discharged and in the chamber 14 the washing liquor. If the separation is to be postponed, this must be done Separating stopper are moved either in the direction of the stopper 10 or the stopper 11. According to the invention it is proposed to install this plug 12 in a molded piece 16 so that it can be displaced in the channel of the control ring 9, that a toothed rack 18 engages in a toothed plate 17 attached to the molded piece and moves by means of the spindle 19 can be. In this way it is possible to continuously adjust the Change the position of the separation zone.

Analog läßt sich dies auch bei.; Plansteuerköpfen vornehmen. Bei dem Plansteuerkopf münden die Rohre, die das Filtrat von den Zellen führen, an der Stirnseite der Nabe bei 19. Diese Stirnseite wird abgedeckt durch eine Steuerscheibe 20, deren Ringkanal durch die Steine 21, 22 und 23, die dem Ringsteuerkopf entsprechenden Abbildungen unterteilt ist. Auch hier kann man, wie oben beschrieben, den Stopfen 22 in ein FormThis can also be done analogously with .; Make plan control heads. In the case of the plan control head, the pipes that lead the filtrate from the cells open at the end of the hub at 19. This Front side is covered by a control disk 20, whose Ring channel through stones 21, 22 and 23, which are the ring control head is divided into corresponding figures. Here too, as described above, the stopper 22 can be shaped

stück fassen und durch Zahnplatte und Zahnstange in seiner Lage verschieben. Wenn man dieses System für Trübfiltrattrennung anwenden will, muß man den Stopfen 11 und den Stopfen 12 durch einen weiteren Stopfen 21' ergänzen, den man dann in der geschilderten Weise verschiebt.grasp the piece and insert it through the toothed plate and rack move its location. When one can apply this system for turbid filtrate separation want, you have to add the plug 11 and the plug 12 by a further plug 21 ', which you then in shifts in the manner described.
