Description

Die Erfindung betrifft eine Vorrichtung zum Vermischen von suspendiertem Faserstoff gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for mixing suspended fibrous material according to the preamble of claim 1.

Die auf einer Papiermaschine verarbeitete Faserstoffsuspension wird oft durch Mischung verschiedener Faserstoffe untereinander und durch Verdünnung mit Dünnstoff, z.B. Siebwasser, gebildet. Der Teil der Papiererzeugungsanlage, dem u.a. diese Aufgabe zufällt, wird üblicherweise als Konstanter Teil bezeichnet. Meist wird eine stark verdünnte Faserstoffsuspension von ca. 1 bis 2 % Stoffdichte über die sogenannte Mischpumpe der Papiermaschine zugeführt, wobei weitere Bearbeitungsaggregate für die Suspension vorhanden sein können.The pulp suspension processed on a paper machine is often through Mix different fiber materials with each other and by dilution with Thin material, e.g. White water, formed. The part of the paper production plant that this task is usually referred to as a constant part. Mostly a highly diluted fiber suspension of approx. 1 to 2% consistency So-called mixing pump fed to the paper machine, with others Processing units for the suspension can be present.

Es ist aus dem Stand der Technik bekannt, zum Vermischen der verschiedenen Faserstoffqualitäten, welche an dieser Stelle in wässerig suspendierter Form vorliegen, diese unmittelbar vor einer Mischpumpe zusammenzuführen. Dazu wird üblicherweise der das Verdünnungswasser führende Ansaugstutzen der Mischpumpe verwendet. Die Mischpumpe dient bekanntlich dazu, die fertige Faserstoffsuspension zum Stoffauflauf zu fördern und dabei den hierin erforderlichen, zumeist beträchtlichen Überdruck zu erzeugen. Auch wenn grundsätzlich in der Mischpumpe infolge der dort stattfindenden Verwirbelung eine Mischung der Komponenten möglich ist, hat sich doch gezeigt, dass die Mischungsqualität nicht immer ausreicht. Insbesondere kann es vorkommen, dass bei stark schwankenden Mengen oder auch beträchtlichen Unterschieden in den Stoffdichten der einzelnen Komponenten eine ungenügende Vermischung erfolgt.It is known from the prior art for mixing the different Fiber qualities, which are present here in aqueous suspended form, bring them together immediately before a mixing pump. This is usually done who uses the intake port of the mixing pump that carries the dilution water. The Mixing pump is known to serve the finished fiber suspension to the headbox to promote and thereby the required, mostly considerable overpressure produce. Even if in principle in the mixing pump as a result of that taking place there Whirling a mixture of the components is possible, it has been shown that the mix quality is not always sufficient. In particular, it can happen that with strongly fluctuating quantities or considerable differences in the Material densities of the individual components are insufficiently mixed.

Aus der DE 41 25 513 A1 ist ein Verfahren entnehmbar, mit dessen Hilfe mehrere Faserstoffqualitäten miteinander oder Faserstoff mit Siebwasser vermischt werden können. Dabei wird der Dickstoff direkt und im wesentlichen zentral in den Stoffstrom des Dünnstoffes eingeleitet, wobei eine relativ hohe Geschwindigkeit des Dickstoffes gefordert wird. Diese Zumischung erfolgt unmittelbar vor der Mischpumpe. Auch wenn die Mischwirkung einer solchen Mischpumpe relativ gut ist, können bei Verwendung des bekannten Verfahrens zeitliche Schwankungen in der Faserstoffqualität auftreten.From DE 41 25 513 A1 one method can be found, with the help of which several Fiber qualities are mixed with each other or fiber with white water can. The thick matter is directly and essentially centrally in the material flow initiated the thin material, with a relatively high speed of the thick material is required. This admixture takes place immediately before the mixing pump. Even if the mixing effect of such a mixing pump is relatively good, when using the known process temporal fluctuations in the fiber quality occur.

Es ist nun Aufgabe der vorliegenden Erfindung, eine Vorrichtung zu schaffen, mit deren Hilfe die Vermischung verschieden gearteter Stoffsuspensionen untereinander in möglichst effektiver Weise gewährleistet wird. Die gute Vermischung soll auch erreicht werden, wenn beträchtliche Unterschiede der Mengen und/oder Stoffdichten der einzelnen Komponenten vorliegen.It is an object of the present invention to provide a device with which Help the mixing of different types of material suspensions with each other in guaranteed as effectively as possible. The good mixing should also be achieved if there are significant differences in the quantities and / or consistencies of the individual components.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 genannten Merkmale vollständig gelöst, wobei die Unteransprüche vorteilhafte Ausführungsformen beschreiben.This object is achieved by those mentioned in the characterizing part of claim 1 Features completely solved, the subclaims advantageous embodiments describe.

Die Erfindung wird erläutert an Hand von Zeichnungen. Dabei zeigen:

The invention is explained with reference to drawings. Show:
Fig. 1
a simplified representation of the device according to the invention;
Fig. 2
a variant;
Fig. 3
an advantageous control concept for the device shown in Fig. 2.

Wie die Fig. 1 an Hand eines typischen Beispieles zeigt, besteht die erfindungsgemäße Vorrichtung aus einem Mischgefäß 5, welches hier als offenes Gefäß ausgeführt ist. Stromaufwärts zu diesem Mischgefäß ist ein Mischrohr 6 angeschlossen, welches zwei Zuleitungen 8 und 9 aufweist, durch die zwei verschiedene Faserstoffsuspensionen 1 und 2 zugegeben werden können. Dabei sind die Zuleitungen 8 und 9 hier in Strömungsrichtung hintereinander senkrecht zum Verlauf des Mischrohres 6 angeordnet. Selbstverständlich können es auch mehr als zwei Zuleitungen sein, wenn die Anzahl der Stoffkomponenten entsprechend höher ist. Die so zusammengeführten Stoffströme gelangen dann stromabwärts in einen Teil des Mischrohres 6, welches mit einem statischen Mischer 7 versehen ist. Dieser ist hier nur angedeutet; statische Mischer sind bekannt. An der Stelle, an der das Mischrohr 6 in das Mischgefäß 5 einmündet, befindet sich ein antreibbarer Rührer 12, welcher eine weitere As shown in FIG. 1 with the aid of a typical example, there is the invention Device from a mixing vessel 5, which is designed here as an open vessel. A mixing tube 6, which has two, is connected upstream of this mixing vessel Has feed lines 8 and 9 through which two different fiber suspensions 1 and 2 can be added. The leads 8 and 9 are here in Flow direction one behind the other perpendicular to the course of the mixing tube 6 arranged. Of course, there can also be more than two supply lines if the Number of fabric components is correspondingly higher. The so merged Material flows then arrive downstream in a part of the mixing tube 6, which with a static mixer 7 is provided. This is only hinted at here; static Mixers are known. At the point where the mixing tube 6 enters the mixing vessel 5 flows out, there is a drivable stirrer 12, which is another

Vermischung der einströmenden und/oder der sich bereits im Mischgefäß 5 befindenden Flüssigkeit bewirkt oder zumindest die Entmischung im Mischgefäß 5 verhindert.Mixing the inflowing and / or those already in the mixing vessel 5 Liquid causes or at least prevents segregation in the mixing vessel 5.

Das Mischgefäß 5 kann mit besonderem Vorteil relativ klein gehalten sein, d.h. sein Volumen ist weit geringer als das, das normalerweise für Mischbütten gewählt wird. Am Boden des Mischgefäßes befindet sich die Ablaufleitung 10, welche stromabwärts in die Zuleitung 11 des Dünnstoffs 3 in die Mischpumpe 4 einmündet. In dieser Ablaufleitung 10 kann eine Pumpe 15 vorhanden sein. Durch die Zugabe des Dünnstoffs 3, der z.B. als Siebwasser von der Papiermaschine abgezogen wurde, wird eine solche Stoffdichte eingestellt, wie sie zur Erzeugung des Papiers im Papiermaschinen- Stoffauflauf benötigt wird. Zur Vermischung dieser beiden Komponenten ist bekanntlich die Mischpumpe 4 ausgelegt. Neben der hier gezeigten Form der Eingabe sind auch andere Möglichkeiten bekannt.The mixing vessel 5 can particularly advantageously be kept relatively small, i.e. his Volume is far less than what is normally chosen for mixed chests. At the The bottom of the mixing vessel is the drain line 10, which is downstream into the Feed line 11 of the thin material 3 opens into the mixing pump 4. In this drain pipe 10 there may be a pump 15. By adding the thin material 3, e.g. as White water has been withdrawn from the paper machine, such a consistency set as used to produce the paper in the paper machine headbox is needed. To mix these two components, it is known that Mixing pump 4 designed. In addition to the form of input shown here, there are also others Possibilities known.

In Fig. 2 ist eine weitere Form der erfindungsgemäßen Vorrichtung gezeigt, bei der das Mischgefäß 5' abweichend von dem in Fig. 1 gezeigten ein geschlossener, unter Überdruck stehender Tank ist. Dadurch kann das Mischsystem unter Druck gehalten werden. Das Mischgefäß 5' enthält einen Überlauf 15, mit dem das Niveau auf einem eingestellten Wert gehalten wird. Es kann auch mit einer Blende 16 versehen sein. Für den Fall, dass eine Rückströmung aus dem Mischrohr 6 abgeführt werden soll, ist fakultativ ein Anschlußstutzen 13 angedeutet.In Fig. 2 a further form of the device according to the invention is shown, in which the Mixing vessel 5 'different from that shown in Fig. 1, a closed, under Overpressure tank is. This allows the mixing system to be kept under pressure become. The mixing vessel 5 'contains an overflow 15, with which the level at one set value is maintained. It can also be provided with an aperture 16. For the case that a backflow is to be discharged from the mixing tube 6 optionally a connection piece 13 indicated.

Die Zugabe der gemischten Faserstoffsuspension erfolgt hier in eine gekrümmte Ansaugleitung für den Dünnstoff 3 mit einem zentralen Düsenrohr 14 für die Faserstoffsuspensionen.The mixed fiber suspension is added here into a curved one Intake line for the thin material 3 with a central nozzle tube 14 for the Fibrous suspensions.

Fig. 3 zeigt exemplarisch ein mögliches Regelkonzept für die in Fig. 2 dargestellte Vorrichtung. Dabei sind die in der Regeltechnik üblichen Bezeichnungen gewählt, so dass sich eine Erläuterung des Konzeptes erübrigt. Bei diesem Beispiel werden insgesamt vier Faserstoffkomponenten zusammengeführt. Deren Mengenregelung ist nur für den Zufluss der Faserstoffsuspension 1 explizit dargestellt. Die Zuflussregelung der anderen Komponenten kann ähnlich erfolgen, wobei deren Mengenverhältnisse untereinander vorgegeben sind.FIG. 3 shows an example of a possible control concept for the one shown in FIG. 2 Contraption. The designations usual in control technology are chosen so that there is no need to explain the concept. In this example, total four fiber components brought together. Their quantity regulation is only for the Inflow of the fiber suspension 1 is shown explicitly. The inflow regulation of the others Components can be made similarly, with their quantitative relationships among themselves are specified.
