Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Kneten von hochkonsistentem Faserstoff
gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for kneading highly consistent fibrous material
according to the preamble of
Eine Knetvorrichtung ist z. B. aus der DE-42 37 433 A1 bekannt. Diese zum Kneten von Altpapier geeignete Vorrichtung dient dazu, den Stoff intensiv mechanisch und eventuell auch thermisch zu bearbeiten, wodurch die darin enthaltenen Störstoffe von den Fasern abgelöst, zerkleinert und/oder unter die Sichtbarkeitsgrenze gebracht werden können. Es gibt auch andere Anwendungen derartiger Knetvorrichtungen. Z.B. kann darin die Faser, sei es Zellstoff oder Altpapier, so bearbeitet werden, daß sie sich kräuselt (curling). Dadurch erhält sie spezifische Verbesserungen, wie z.B. ein größeres Volumen. Der für den Knetvorgang bestimmte Ausgangsstoff hat bereits eine teigige oder weich-krümelige Form, ist also nicht mehr mit Holz-Hackschnitzeln oder noch gröberen Stoffen vergleichbar. Anders auch als z. B. bei Papierstoff-Mahlrefinern wird bei derartigen Maschinen der Faserstoff nicht in einer pumpfähigen Suspension bearbeitet, sondern eben als Hochkonsistenzstoff, vorzugsweise mit einem Trockengehalt zwischen 15 und 40 %. Auf diese Weise lassen sich beträchtliche Scherkräfte in den Faserstoff übertragen, wodurch die genannten Ziele erreichbar sind, ohne daß dabei eine wesentliche Veränderung der Faserlänge erfolgt. In vielen Fällen wird die Wirkung der mechanischen Behandlung durch Hitze weiter verstärkt, z.B. durch Einstellen einer Faserstofftemperatur von 90° Celsius oder noch darüber.A kneading device is e.g. B. known from DE-42 37 433 A1. This for kneading Device suitable for waste paper serves to intensively mechanically and possibly the substance can also be processed thermally, thereby removing the contaminants contained in the fibers can be detached, crushed and / or brought below the visibility limit. There are other applications of such kneaders. For example, can the Fiber, be it cellulose or waste paper, is processed so that it curls (curling). This gives them specific improvements, such as a bigger one Volume. The starting material intended for the kneading process already has a pasty or soft-crumbly shape, so is no longer with wood chips or still coarser substances comparable. Other than z. B. in pulp refiners in such machines the pulp is not in a pumpable suspension edited, but just as a high consistency substance, preferably with one Dry content between 15 and 40%. In this way, considerable Transfer shear forces into the fiber material, whereby the stated goals can be achieved, without any significant change in fiber length. In many cases the effect of mechanical treatment is further enhanced by heat, e.g. by setting a fiber temperature of 90 ° Celsius or even higher.
Beim Kneter verbleibt der Stoff in der Regel 15 Sekunden bis zu mehreren Minuten in den Bearbeitungsräumen und wird infolge des Abstandes von mehr als 3 mm zwischen den Werkzeugen überwiegend durch Faser-Faser-Reibung bearbeitet. Bekanntlich wird dadurch die Faser geschont und werden die Bearbeitungswerkzeuge nur langsam verschlissen. Der Grundaufbau des Kneters ist fast immer wie am Beispiel der DE-42 37 433 A1 erkennbar: Der Rotor ist im wesentlichen zylindrisch, und der Stoff wird axial zwischen stehenden und bewegten Knetzähnen hindurchgefördert. Solche Kneter haben sich besonders für den Altpapiereinsatz seit langem bewährt. Der Transport des Stoffes durch die Bearbeitungszone wird dabei meist sowohl durch Schrägstellung der Bearbeitungszähne als auch durch eine geeignete Fördereinrichtung gesichert, die z.B. als Schneckenwendel auf der Kneterwelle ausgebildet ist. Die Förderparameter liegen damit praktisch fest.In the kneader, the substance usually stays in for 15 seconds to several minutes the processing rooms and is due to the distance of more than 3 mm between the tools are mainly processed by fiber-fiber friction. As is known this protects the fiber and the processing tools become slow worn. The basic structure of the kneader is almost always as in the example of DE-42 37 433 A1 recognizable: The rotor is essentially cylindrical, and the material becomes conveyed axially between standing and moving kneading teeth. Such kneaders have long proven themselves especially for the use of waste paper. The transportation of the Material through the processing zone is usually both by tilting the Machining teeth and secured by a suitable conveyor, which e.g. is designed as a helix on the kneader shaft. The funding parameters are so practically firm.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Kneten von hochkonsistentem Faserstoff zu schaffen, die ohne nennenswerten Mehraufwand eine Änderungsmöglichkeit der Transportbewegung in der Bearbeitungszone bietet.The invention is therefore based on the object of a device for kneading to create highly consistent fibrous material, which without any significant additional effort Possibility to change the transport movement in the processing zone.
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
Die Vorderseite der Zähne eines solchen Knetwerkzeuges bewegt sich relativ auf den Faserstoff zu. Da die an der Vorderseite vorhandene Schräge eine Schiebe- und Umlenkbewegung des zu transportierenden Stoffes in die Transportrichtung bewirkt, findet eine Unterstützung des Stofftransportes im Kneter statt. Voraussetzung hierfür ist die Relativbewegung zwischen der Schräge und dem Faserstoff, die entweder dadurch entstehen kann, daß der betreffende Zahn zum bewegten Knetwerkzeug gehört oder dadurch, daß ein feststehender Zahn von einem in Umfangsrichtung bewegten Stoff angeströmt wird. Bei der erfindungsgemäß ausgestatteten Vorrichtung besteht nunmehr die Möglichkeit, durch einfaches Wenden eines Zahnes oder einer Gruppe von Zähnen eines oder mehrerer Knetwerkzeuge die bisher als Rückseite verwendete Fläche des Zahnes auf die Vorderseite zu bringen. Da die Transportwirkung von dem Winkel abhängt, den die Schräge gegenüber der Bewegungsrichtung des Zahnes oder des Stoffes am unbewegten Zahn einnimmt, kann durch Wenden eines solchen Zahnes, z.B. um 180° bei unterschiedlichen Winkeln der Schrägen auch eine unterschiedliche Transportwirkung erzielt werden. The front of the teeth of such a kneading tool moves relative to the Pulp too. Since the incline on the front is a sliding and Deflection movement of the substance to be transported in the transport direction causes the mass transfer is supported in the kneader. Prerequisite for this is the relative movement between the bevel and the pulp, either by doing so can arise that the tooth in question belongs to the moving kneading tool or in that a fixed tooth of a material moved in the circumferential direction is flowed to. The device equipped according to the invention now exists the possibility of simply turning a tooth or a group of teeth one or more kneading tools the surface of the previously used as the back To bring tooth to the front. Because the transport effect of the angle depends on the incline in relation to the direction of movement of the tooth or the material on the unmoved tooth, can be turned by turning such a tooth, e.g. by 180 ° with different angles of the slopes also a different one Transport effect can be achieved.
Das Wenden in der beschriebenen Form führt also auf einfache Art und Weise zu einem Ändern der Förderwirkung an dem betreffenden Zahn. Eine solche Änderung kann Vorteile bringen, wenn bei der Auslegung der Maschine Bedingungen berücksichtigt werden sollen, die nicht dem ursprünglichen Standard entsprechen. Das kann z.B. die Erfordernis eines größeren oder kleineren Durchsatzes sein. Weiterhin kann es von Vorteil sein, gezielt auf die Transportvorgänge derart Einfluß zu nehmen, daß in bestimmten Teilen der Bearbeitungszonen eine höhere Transportgeschwindigkeit und in anderen Teilen eine geringere Transportgeschwindigkeit herrschen soll. Dadurch würde eine Kompressionszone entstehen, durch die der Stoff zwangsweise hindurchtritt. Eine Kompressionszone kann z.B. als Dampfsperre dienen. Aber auch technologische Vorteile beim eigentlichen Knetvorgang sind hierdurch erzielbar. Eine Einflußnahme dieser Art auf den Stofftransport im Kneter kann aber durchaus für verschiedene Einsatzfälle ein und desselben Kneters unterschiedlich gewünscht werden. In einem solchen Falle muß zur Anpassung erfindungsgemäß lediglich ein Teil der oder alle entsprechend ausgestatteten Zähne gewendet werden. Selbst in den Fällen, in denen ursprünlich die Schrägen an der Vorder- und Rückseite gleich sind, kann durch Wenden eine weniger verschlissene Fläche zum Transport des Stoffes angeboten werden.Turning in the form described thus leads to a simple manner Change the promotional effect on the tooth in question. Such a change can Bring advantages if conditions are taken into account when designing the machine that do not meet the original standard. This can e.g. the A need for larger or smaller throughput. Furthermore, it can be from Be advantageous to influence the transport processes in such a way that in certain parts of the processing zones a higher transport speed and in other parts should have a lower transport speed. This would a compression zone is created through which the fabric forcibly passes. A Compression zone can e.g. serve as a vapor barrier. But also technological advantages this can be achieved in the actual kneading process. An influence of this kind However, the mass transfer in the kneader can be used for various applications and the same kneader are desired differently. In such a case to adapt according to the invention only a part of or all accordingly equipped teeth are turned. Even in the cases where the Slopes on the front and back are the same, can be turned one less worn area for transporting the fabric.
In bestimmten Extremfällen, bei denen eine ausgeprägte Kompression des Stoffes zonenweise gewünscht wird, kann die Schräge sogar so gewählt werden, daß sie den Stofftransport bremst. Natürlich würde durch eine vor- oder nachgelagerte Transporteinrichtung dennoch ein Durchsatz durch die Maschine erzwungen werden müssen.In certain extreme cases where there is a pronounced compression of the substance is desired zone by zone, the slope can even be chosen so that the Material transport brakes. Of course, an upstream or downstream one would Transport device can still be forced throughput through the machine have to.

Figur 1a zeigt in abgewickelter Form die Aufsicht auf den Teil eines bewegbaren
Knetwerkzeuges 1, welches zu einem Kneter mit axialem Stofffluß gehört. Man erkennt
eine Zahnreihe mit einer Anzahl von Zähnen 2. Geschnitten angedeutet sind die Zähne 2'
eines feststehenden Knetwerkzeuges. Die Zähne 2, 2' sind sowohl auf der Vorderseite als
auch auf der Rückseite abgeschrägt. Dabei haben in dem hier gezeigten Beispiel alle
Zähne eine im wesentlichen gleiche Form, was aber nicht immer so sein muß (s. auch
Fig. 3). Aufgrund ihrer Anordnung in der Knetvorrichtung werden die Zähne 2 bei
Betrieb in Umfangsrichtung (Pfeil 3) bewegt. Bei einer solchen Bewegung der
Zahnfußnormalen N wird hier eine Ebene E aufgespannt, im Schnitt dargestellt. Die
Transportrichtung T des Faserstoffes steht senkrecht auf dieser Ebene E. Dabei wird nur
der eigentliche Stofftransport durch den Kneter hindurch betrachtet, selbstverständlich
findet in der Regel außerdem eine Umfangsbewegung des Faserstoffes statt. Die Winkel,
die die Schrägen gegenüber der Transportrichtung T haben, sind mit Winkel α 1 an der
Vorderseite und Winkel α 2 an der Rückseite - jeweils in der Stellung vor dem Wenden
des Zahnes - angegeben.Figure 1a shows in a developed form the supervision of the part of a
Fig. 1 b stellt die Teile der Fig. 1 a nach dem Wenden der Zähne 2 und 2' um 180° dar.
Die Transportwirkung an der Vorderseite der Zähne ist wegen der geringeren
Schrägstellung geringer. Selbstverständlich könne diese Zahnflächen auch gewölbt sein.
Entscheidend ist ihre Transportwirkung.Fig. 1 b shows the parts of Fig. 1 a after turning the
Figur 2 zeigt eine etwas andere Befestigung von den zur erfindungsgemäßen Vorrichtung
gehörenden Zähnen 2. Man erkennt den Teil einer für eine Axialmaschine bestimmte
Leiste 4, welche mehrere Zähne 2 enthält, die dann zu jeweils verschiedenen
Zahnreihen dieses Knetwerkzeuges gehören. Hier kann das Wenden der Zähne durch
Wenden dieser Leiste 4 erfolgen. Eine solche Leiste kann zum Rotor oder Stator
gehören, auf dem sie ihrer Länge nach im wesentlichen axial ausgerichtet befestigt ist.Figure 2 shows a slightly different attachment of the device to the
Figur 3 zeigt im Schnitt eine axial aufgebaute Knetvorrichtung, bei der also die
Transportbewegung des Faserstoffes auch wieder axial erfolgt. Die Darstellung ist grob
schematisch und enthält z.B. nur einen geringen Teil der real vorhandenen Zähne. Der
Faserstoff S wird beim Eintrag durch eine Förderschnecke 5 in die eigentliche
Bearbeitungszone gepreßt. In dieser befinden sich mehrere Zahnreihen, deren Zähne 2,
2' alternierend angeordnet am Rotor 6 oder am Statorgehäuse 7 befestigt sind. Dabei
sind die zum Statorgehäuse 7 gehörenden Zähne 2' geschnitten gezeichnet. Ein Teil von
ihnen hat hier eine variierte, stark abgerundete Form, ein anderer Teil ist kubisch aber
ohne Anschrägungen. An einigen von der Seite sichtbaren Zähnen sind die
Zahnfußnormalen N angedeutet, deren Umfangsbewegung die Ebene E (Fig. 1 a, 1 b)
aufspannt. Der in Strömungsrichtung letzten Statorstufe folgt hier eine einstellbare
Drossel 8 zur Erzielung eines Gegendruckes. Durch diese Maßnahme kann die Wirkung
der Knetvorrichtung weiter verbessert werden. Nach Passieren der Drossel 8 tritt der
geknetete Stoff S' aus dem Statorgehäuse 7 wieder aus.Figure 3 shows in section an axially constructed kneading device, in which the
Transport movement of the fibrous material also takes place axially again. The presentation is rough
schematic and contains e.g. only a small part of the real teeth. The
Fibrous material S is fed into the
Fig. 4 zeigt den Teil eines Knetwerkzeuges, das zu einem Radialkneter gehört. Der
Stofftransport mit Transportrichtung T erfolgt also von innen radial nach außen. Durch
die Umfangsbewegung (Pfeil 3) der Zahnfußnormalen N' der Zähne 2 wird eine
zylindrische Fläche F aufgespannt. Zum Wenden der Zähne 2 werden diese einzeln
gelöst; die Löcher 9 sind für Befestigungsschrauben vorgesehen. Der zum Stator
gehörende Zahn 2' ist nur angedeutet. Abweichend vom hier gezeigten Beispiel kann er
sich in seiner Form von den bewegten Zähnen 2 durchaus unterscheiden.
Es ist bei Realisierung der Erfindung auch möglich, die zum Wenden eingerichteten
Zähne nur am Rotor oder nur am Stator vorzusehen.Fig. 4 shows the part of a kneading tool that belongs to a radial kneader. The
