Abstract
Description
Die Erfindung betrifft ein Verfahren zur Dispergierung von Papierfaserstoff gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for dispersing paper pulp according to the Preamble of claim 1.
Verfahren der o. g. Art werden z. B. zur Qualitätsverbesserung von Faserstoff eingesetzt, der aus Altpapier gewonnen wurde. Es ist bekannt, dass Papierfasertoff durch Dispergieren homogenisiert und dadurch wesentlich verbessert werden kann. Dazu wird ein hochkonsistenter Faserstoff hergestellt, der einen Trockengehalt zwischen 15 und 35% aufweist. In vielen Fällen wird bei einer Temperatur dispergiert, die weit über der Umgebungstemperatur liegt. Dispergergarnituren, mit denen Verfahren dieser Art durchgeführt werden, sind kompakt und haben eine ausgezeichnete Dispergierwirkung. Sie setzen allerdings einen gleichmäßigen Stoffstrom voraus. Da die Verweilzeit des Stoffes zwischen ihnen nur sehr kurz ist, können Ungleichmäßigkeiten nicht ausgeglichen werden. Die Folge wäre eine ungleichmäßige Dispergierung.Procedure of the above Kind z. B. used to improve the quality of fiber, which was obtained from waste paper. It is known that paper pulp through Dispersing homogenized and can thus be significantly improved. This will a high-consistency fibrous material that has a dry content between 15 and 35%. In many cases it is dispersed at a temperature that is well above the ambient temperature. Disperger sets with which processes of this type are compact and have an excellent dispersing effect. However, they require an even material flow. Since the dwell time of the Substance between them is very short, irregularities cannot be balanced. The result would be an uneven dispersion.
Bei dem durchgeführten Eindickprozess wird ein beträchtlicher Teil des vorher noch im Faserstoff vorhandenen Wassers ausgepresst, wodurch erstens seine Viskosität bei der Dispergierung wesentlich ansteigt und zweitens gegebenenfalls weniger Wasser mit erwärmt werden muss. Eine besonders wirtschaftliche Maschine für die Eindickung ist die Schneckenpresse. Bei einer Schneckenpresse wird die Faserstoffsuspension zwischen einer Förderschnecke und einem diese umgebenden gelochten Mantel ausgepresst, wobei das Wasser durch die Löcher des Mantels austritt. Der dabei entstehende Pressling oder Pfropfen wird aus der Schnecke ausgedrückt und zerbricht in Teilstücke. Teilstücke sind relativ grob und führen zu einem ungleichmäßigen Mengenstrom. During the thickening process, a considerable part of the previously Fibrous water squeezed out, which firstly its viscosity at the Dispersion increases significantly and secondly less water if necessary must be heated. A particularly economical machine for thickening is the screw press. In a screw press, the fiber suspension is between a screw conveyor and a perforated jacket surrounding it, wherein the water comes out through the holes in the jacket. The resulting compact or Grafting is squeezed out of the snail and breaks into pieces. Are sections relatively coarse and lead to an uneven flow.
Aus der DE 197 12 653 A1 ist eine Dispergiervorrichtung bekannt, in die der aus einer Schneckenpresse stammende Pfropfen direkt eingespeist wird. Dabei wird er in einem Zerkleinerungswerkzeug mit Schabern oder Messern zerrieben, die sich im Dispergerzulauf befinden.From DE 197 12 653 A1 a dispersing device is known, in which the from a Screws originating from the screw press are fed directly. He is in one Shredding tool with scrapers or knives, which are in the Disperger inflow are.
Es ist Aufgabe der Erfindung, eine Vorrichtung zu schaffen, mit der es gelingt, den aus der Schneckenpresse kommenden hochkonsistenten Pfropfen so der Dispergierung zuzuführen, dass eine besonders gleichmäßige Dispergierung bei hoher Betriebssicherheit gewährleistet ist.It is an object of the invention to provide a device with which it is possible the highly consistent plugs of the screw press thus dispersing that a particularly uniform dispersion at high Operational safety is guaranteed.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 genannten Merkmale vollständig gelöst.This object is achieved by the features mentioned in the characterizing part of claim 1 completely solved.
Mit Hilfe des neuen Verfahrens ist es möglich, einen Hochkonsistenzstoff herzustellen, der sich einwandfrei in einem Disperger bearbeiten lässt. Die erfindungsgemäß verwendete Schlegelwalze nimmt die durch das Abpressen von Wasser komprimierten Pfropfenstücke auf und zerteilt sie, insbesondere da die umlaufenden Schlegel mit den am Umfang feststehenden Prallstücken zusammenwirken. Größere Brocken verbleiben länger im Bearbeitungsbereich, bis sie passieren können, so dass der Stofffluss zum Disperger sehr gleichmäßig wird. Er wird dann im radial inneren Bereich der Garnituren weiter zerkleinert und verwirbelt, wobei sehr feine Faserkrümel entstehen. Falls gewünscht, erfolgt die Einspeisung von Dampf in eine stromabwärts folgende Aufheizzone der Garnituren, um den Stoff auf die notwendige Temperatur aufzuheizen. Dabei reicht infolge der vorangegangenen Zerkleinerung eine relativ kurze Aufheizzeit aus. Die eigentliche Dispergierung, d. h. Veränderung der Stoffeigenschaften erfolgt in der Dispergierzone der Garnituren, die sich stromabwärts anschließt.With the help of the new process it is possible to produce a high consistency substance that can be processed perfectly in a disperger. The invention used drumstick takes the compressed by the squeezing of water Pieces of graft on and cut them up, especially since the circumferential beater with the interact with baffles fixed on the circumference. Larger chunks remain longer in the processing area until they can pass, so that the material flow to the Disperger becomes very even. It is then in the radially inner area of the Sets further crushed and swirled, creating very fine fiber crumbs. If desired, steam is fed into a downstream one Heating zone of the clothing to heat the fabric to the necessary temperature. As a result of the previous shredding, a relatively short heating-up time is sufficient out. The actual dispersion, i.e. H. Change of material properties takes place in the dispersion zone of the sets, which follows downstream.

Die Fig. 1 zeigt Ausschnitte einer Anlage, die zur Durchführung des erfindungsgemäßen Verfahrens besonders gut geeignet ist. Man erkennt im oberen Teil des Bildes die Schneckenpresse 8, in der aus dem wasserhaltigen Papierfaserstoff 51 ein großer Teil des Wassers W ausgepresst wird. Dadurch wird ein kompaktierter hochkonsistenter Faserstoff 52 erzeugt, der in grobstückiger Form am Ende der Pressstrecke abbricht und durch einen kurzen Fallschacht 10 in die darunter befindliche Verteilvorrichtung 9 herabfällt. Diese enthält als wesentliches Bauteil eine Schlegelwalze 1 mit daran befestigten umlaufend bewegten Schlegeln 2. Die Schlegelwalze 1 arbeitet mit an der Peripherie, also am Gehäuse der Verteilvorrichtung 9 angebrachten feststehenden Prallstücken 3 zusammen, so dass die bereits beschriebene Wirkung eintreten kann. Solche Prallstücke können, wie hier gezeichnet, stabförmig mit radialer Ausrichtung sein oder z. B. auch kubisch oder plattenförmig. Durch einen Falltrichter 11 gelangt der so behandelte hochkonsistente Faserstoff 53 in eine Förderschnecke 7, die unmittelbar vor dem Disperger 4 installiert ist. Diese Förderschnecke 7 treibt den Faserstoff 53 in den zentralen Bereich des Dispergers 4, so dass er zwischen die Dispergergarnituren 5 und 6 gelangt und dispergiert wird. In vielen Fällen wird der Stoff zur Dispergierung auf eine höhere Temperatur gebracht, wozu hier eine Dampfeinspeisung 12 vorhanden ist. Mit Hilfe dieser Dampfeinspeisung 12 wird heißer Wasserdampf D in den Raum zwischen die beiden Dispergergarnituren eingespeist. Zweckmäßigerweise erfolgt das in einer ringförmigen Heizzone 13, die sich radial innerhalb des eigentlichen Dispergierbereiches 14 der Garnituren befindet. Im Dispergierbereich 14 wirken die ineinandergreifenden Zahnreihen so, dass in der an sich bekannten Weise der hochkonsistente Papierfaserstoff dispergiert wird. Danach tritt der dispergierte Papierfaserstoff 54 aus dem Disperger durch eine Bodenöffnung aus. Fig. 1 shows parts of a plant which is particularly suitable for carrying out the inventive method. The screw press 8 can be seen in the upper part of the picture, in which a large part of the water W is pressed out of the water-containing paper pulp 51 . This produces a compacted, highly consistent fibrous material 52 , which breaks off in large pieces at the end of the pressing section and falls through a short chute 10 into the distribution device 9 located underneath. This contains, as an essential component, a flail roller 1 with flails 2 which are rotated and attached to it. The flail roller 1 cooperates with fixed impact pieces 3 attached to the periphery, that is to say on the housing of the distribution device 9 , so that the effect already described can occur. Such impact pieces can, as drawn here, be rod-shaped with a radial orientation or z. B. also cubic or plate-shaped. The high-consistency fibrous material 53 treated in this way passes through a drop funnel 11 into a screw conveyor 7 which is installed directly in front of the disperser 4 . This screw conveyor 7 drives the fibrous material 53 into the central area of the disperser 4 , so that it gets between the disperser sets 5 and 6 and is dispersed. In many cases, the substance for dispersion is brought to a higher temperature, for which purpose a steam feed 12 is present. With the help of this steam feed 12 , hot water vapor D is fed into the space between the two disperser sets. This is expediently carried out in an annular heating zone 13 , which is located radially within the actual dispersion region 14 of the clothing. In the dispersing area 14 , the intermeshing rows of teeth act in such a way that the highly consistent paper pulp is dispersed in the manner known per se. Thereafter, the dispersed pulp 54 exits the disperser through a bottom opening.
Die Fig. 2 verdeutlicht die Anordnung der zur Durchführung des Verfahrens verwendeten Vorrichtungen in einer anderen Ansicht, und zwar mit Blickrichtung auf den Disperger 4. Durch Verwendung einer gemäß den Ansprüchen gebauten Verteilvorrichtung 9 wird nicht nur eine optimale Verteilung des an der Schneckenpresse 8 anfallenden Stoffes erreicht, sondern auch der Vorteil einer platzsparenden Anordnung erzielt. Bei industrieller Durchführung des Verfahrens muss nämlich wegen der relativ großen Mengen eine Schneckenpresse 8 mit relativ großem Wellendurchmesser gewählt werden. Der am Ende der Schneckenwelle anfallende Faserstoff ist nicht fließfähig und sollte daher im wesentlichen frei senkrecht herabfallen können. Die Lage der Verteilvorrichtung 9 in der gezeichneten Weise ermöglicht es, den über den ganzen Durchmesser der Schneckenpresse 8 anfallenden Faserstoff zu erfassen und nach entsprechender Behandlung in den darunterliegenden Fallschacht 10 abzuleiten. Es ist daher günstig, die Schlegelwalze 1 im rechten Winkel zur Hauptförderrichtung der Schneckenpresse 8 anzuordnen. Diese Einheit, also Schneckenwelle und Verteilvorrichtung 9, kann dann relativ zum Disperger 4 je nach Platzverhältnissen zweckmäßig angeordnet werden. FIG. 2 illustrates the arrangement of the devices used to carry out the method in a different view, specifically with a view of the disperger 4 . By using a distribution device 9 constructed in accordance with the claims, not only is an optimal distribution of the material accumulating on the screw press 8 achieved, but also the advantage of a space-saving arrangement is achieved. When the method is carried out on an industrial scale, a screw press 8 with a relatively large shaft diameter must be selected because of the relatively large quantities. The fibrous material obtained at the end of the worm shaft is not flowable and should therefore be able to fall down essentially freely vertically. The position of the distribution device 9 in the manner shown makes it possible to detect the fibrous material accumulating over the entire diameter of the screw press 8 and, after appropriate treatment, to discharge it into the chute 10 below. It is therefore favorable to arrange the flail roller 1 at right angles to the main conveying direction of the screw press 8 . This unit, that is, worm shaft and distribution device 9 , can then advantageously be arranged relative to the disperser 4, depending on the space available.
Den grundsätzlichen Aufbau der Verteilvorrichtung 9 mit der Schlegelwalze 1 zeigt die Fig. 3. Die Schlegelwalze 1 mit Länge L enthält eine Anzahl von Schlegeln 2, deren äußerste Enden auf einem Kreis dem Durchmesser D umlaufen. Sie wirken mit den am Gehäuse 15 dieser Vorrichtung befestigten Prallstücken 3 zusammen. Dadurch wird erreicht, dass der ankommende grobstückige Papierfaserstoff zunächst zerkleinert wird. Die Zerkleinerung kann mit relativ geringen Kräften erfolgen, was darauf zurückzuführen ist, dass der hier anfallende Papierfaserstoff lediglich komprimiert ist und dass es nur darauf ankommt, diesen Verbund wieder aufzulösen. Das ist nicht vergleichbar z. B. mit dem in feuchten Bahnen vorliegenden Altpapier, wie es z. B. in einen Stofflöser eingetragen wird. Zweckmäßigerweise werden die Abstände a zwischen den umlaufenden Schlegeln 2 und den jeweils benachbarten feststehenden Prallstücken 3 so gewählt, dass das Passieren von noch zu wenig zerteilten Stoffbrocken verhindert wird. Eventuell muss dieser Abstand a durch einen einfachen Versuch ermittelt werden. Es könnte auch von Vorteil sein, ihn veränderbar zu machen, so dass die Maschine auf unterschiedliche Anforderungen abgestimmt werden kann. Ähnliches ist zu der Form der Schlegel 2 oder Prallstücke 3 zu sagen. Hier sind recht einfache Formen dargestellt, um lediglich die Funktion zu zeigen. Sie können z. B. auch sichelförmig oder in Umfangsrichtung gesehen schräg gestellt sein. Es ist auch denkbar, sie mit verschleißfesten Aufpanzerungen zu versehen, um ihre Standzeiten zu verlängern.The basic structure of the distribution device 9 with the flail roller 1 is shown in FIG. 3. The flail roller 1 with length L contains a number of flails 2 , the extreme ends of which run around a circle of diameter D. They interact with the impact pieces 3 attached to the housing 15 of this device. This ensures that the incoming coarse paper pulp is first shredded. The comminution can be carried out with relatively low forces, which is due to the fact that the paper pulp obtained here is only compressed and that it is only important to dissolve this composite again. This is not comparable e.g. B. with the waste paper present in wet webs, as z. B. is entered into a pulper. The distances a between the rotating flails 2 and the respectively adjacent fixed impact pieces 3 are expediently chosen such that the passage of chunks of material which have not yet been sufficiently divided is prevented. This distance a may have to be determined by a simple experiment. It could also be advantageous to make it changeable so that the machine can be adapted to different requirements. The same can be said of the shape of the flails 2 or impact pieces 3 . Quite simple forms are shown here, just to show the function. You can e.g. B. also be seen crescent or slanted in the circumferential direction. It is also conceivable to provide them with wear-resistant armouring in order to extend their service life.
