Abstract
Description
Die Erfindung betrifft einen Stofflöser zur Zerkleinerung und Suspendierung von Papierstoff gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a pulper for comminution and suspension of pulp according to the preamble of
Stofflöser dieser Art werden hauptsächlich angewendet, um lufttrockenes Zellstoffmaterial oder Altpapier in Suspension zu bringen. Das eingetragene Material wird in großen Stücken, Bahnen oder gepressten Ballen mit Wasser intensiv vermischt, wozu in der Regel ein Misch- und Zerkleinerungsrotor eingesetzt wird. Ein Stofflöser besteht im Wesentlichen aus einem Behälter für die Suspension und dem schon genannten Rotor. In vielen Fällen enthält er auch ein Sieb im Bodenbereich, durch das die Suspension abgepumpt werden kann.Pulpers of this type are mainly used to suspend air-dry pulp or waste paper. The registered material is intensively mixed in large pieces, webs or pressed bales with water, which is usually a mixing and crushing rotor is used. A pulper consists essentially of a container for the suspension and the already mentioned rotor. In many cases, it also contains a sieve in the bottom area, through which the suspension can be pumped.
Verständlicherweise werden solche Stofflöser ständig optimiert, wobei im Wesentlichen eine schnelle und kraftwirtschaftliche Auflösung angestrebt wird. Als Standardtyp für einen Stofflöser hat sich ein senkrecht stehender zylindrischer Behälter mit einem Rotor im Bodenbereich durchgesetzt. In diesem Behälter wird Wasser und der aufzulösende Stoff von oben zugegeben und mit Hilfe des Rotors eine Trombenströmung in der Suspension erzeugt, bei der also im zentralen Bereich der Stoff vom Rotor nach unten angesaugt und im Bodenbereich radial nach außen gedrückt wird, wodurch sich eine Umtriebsströmung ergibt. Es sind auch Strömungsmaßnahmen bekannt, um diese Umtriebsströmung zu steuern. So wird z.B. durch entsprechende Strömungseinbauten (Schikanen) an der Behälterwand die Umfangsströmung gebremst, da diese nur einen geringen Beitrag zur Auflösung bringt. Die Förderung des eigentlichen Umtriebs, d.h. der wiederholte Transport des aufzulösenden Stoffes in den Rotorbereicht bringt dagegen eine Verbesserung des Effektes. Auch wird angestrebt, den frisch eingetragenen Stoff möglichst schnell in die Suspension einzuziehen. Aus diesen Gründen ist auch schon viel Entwicklung an den Rotoren und Behältern der Stofflöser betrieben worden.Understandably, such pulpers are constantly being optimized, with the aim of achieving a fast and efficient dissolution. The standard type for a pulper is a vertical cylindrical container with a rotor in the bottom area. In this container, water and the material to be dissolved is added from above and generated with the help of the rotor Trombenströmung in the suspension, ie in the central region of the fabric is sucked down from the rotor and pressed radially outward in the bottom region, resulting in a Umtriebsströmung results. There are also flow measures known to control this Umtriebsströmung. For example, by appropriate flow installations (baffles) on the vessel wall, the circumferential flow is slowed down, as this brings only a small contribution to the resolution. The promotion of the actual Umtriebs, ie the repeated transport of the substance to be dissolved in the Rotorbereicht, however, brings an improvement of the effect. Also, the aim is fresh absorbed substance as quickly as possible into the suspension. For these reasons, much development has been carried out on the rotors and containers of pulpers.
In der
Einen anderen Versuch, Stofflöser dieser Art zu verbessern, zeigt die
Zur Verbesserung des Umtriebes sind auch schon unkonventionelle Wege beschritten worden, wie z.B. gemäß
Der Erfindung liegt die Aufgabe zu Grunde, die bekannten Stofflöser ohne wesentlichen Mehraufwand zu verbessern, wobei insbesondere der Einzug des Materials verbessert werden soll. Der Stofflöser soll schneller und/oder wirtschaftlicher auflösen können.The invention is based on the object to improve the known pulper without significant overhead, in particular, the collection of the material to be improved. The pulper should be able to dissolve faster and / or more economically.
Diese Aufgabe wird an einem im Oberbegriff des Anspruchs 1 beschriebenen Stofflöser durch die im Kennzeichen genannten Maßnahmen gelöst.This object is achieved on a pulper described in the preamble of
Es hat sich nämlich gezeigt, dass durch die besondere Form des Behälters ein schnellerer Einzug des eingetragenen Papierstoffes und eine Verbesserung des Umtriebes möglich ist. Der gesamte Auflösevorgang läuft schneller ab, was eine bessere Maschinennutzung sowie eine Energieersparnis bewirkt. Der verbesserte Auflöseeffekt lässt sich durch die schnellere Abnahme des Stippengehaltes in der Fasersuspension feststellen.It has been shown that a faster collection of the registered pulp and an improvement of the rotation is possible by the special shape of the container. The entire dissolution process is faster, resulting in better machine utilization and energy savings. The improved Dissolution effect can be determined by the faster decrease of the speck content in the fiber suspension.
Die Erfindung wird erläutert an Hand von Zeichnungen. Dabei zeigen:

- Figur 2:
- Stofflöser der Fig. 1, Ansicht von oben.
- FIG. 1:
- Schematically a section through a pulper according to the invention, side view;
- FIG. 2:
- Pulper of Fig. 1, top view.
Der geschnitten in Seitenansicht gezeichnete Stofflöser der Fig. 1 ist eine typische Form der Erfindung. Der Papierstoff S wird zusammen mit Wasser W in einen Behälter 1 eingegeben. Bei Betrieb des Stofflösers befindet sich im Behälter 1 eine Mischung aus Wasser und Papierstoff, welcher teilweise schon zerkleinert ist. Diese also mit groben und feinen Feststoffen versehene Suspension wird durch den im Bodenbereich des Behälters 1 angeordneten Rotor 2 in Umtrieb versetzt. Der Rotor wird durch einen nicht gezeigten Motor angetrieben. Wesentlich für diesen erfindungsgemäßen Stofflöser ist, dass die Mittellinie 3 des Rotors 2 gegenüber der Mittellinie 4 des Behälters 1 seitlich versetzt angeordnet ist. Die Exzentrizität E dieses Versatzes ist bei einem zylindrischen Behälter 1 vorzugsweise so groß wie dessen halber Durchmesser D1 mit einer Toleranz von ± 30 %.The pulper of Fig. 1 drawn in side elevation is a typical form of the invention. The pulp S is entered into a
Die Suspension wird vom Rotor 2 nach unten gezogen, wodurch etwa längs der Mittellinie 3 des Rotors 2 eine abwärts gerichtete Strömung entsteht. In Folge der Pumpwirkung des Rotors wird die Suspension am Boden des Behälters 1 radial nach außen gefördert und gelangt dadurch zu dessen Seitenwand 5. Insgesamt entsteht dadurch eine Zirkulationsströmung. Wie an sich bekannt, wird bei diesem beschriebenen Auflösevorgang durch hydraulische Kräfte und durch Kontakt zwischen Rotor 2 und Papierstoff die Zerkleinerung und Suspendierung des Papierstoffs bewirkt. Papierstoffteile, die genügend zerkleinert sind, können - wie hier gezeigt - durch ein Siebblech 6 hindurch in eine Kammer 9 gelangen und als faserstoffhaltige Suspension P abgeführt werden. Ein solcher Stofflöser kann sowohl kontinuierlich als auch diskontinuierlich betrieben werden. Das Siebblech 6 ist nicht unbedingt erforderlich. Der übliche Feststoffanteil in der Suspension P beträgt in der Regel um die 3 bis 6 %, ist aber nicht darauf beschränkt.The suspension is pulled down by the rotor 2, whereby approximately along the
Die exzentrische Rotoranordnung entfaltet ihre günstige Wirkung besonders dann, wenn der Boden 7 des Behälters 1 - außerhalb des Siebbereiches - eine ausgeprägte Schräge aufweist. Dieser so abgebildete Bodenwinkel α ist vorzugsweise zwischen 15° und 60°. Bei ca. 30° liegt hinsichtlich Wirkung, Behältervolumen, Bauaufwand und Platzbedarf eine besonders günstige Ausführung vor.The eccentric rotor assembly unfolds its beneficial effect, especially when the
An der dem Rotor 2 gegenüber liegenden Innenseite der Seitenwand 5 des Behälters 1 befindet sich eine vertikale Strömungsbarriere 8, die in einer einfachen Ausführung als rechtwinkeliges Winkelprofil ausgebildet sein kann, das sich senkrecht vom Boden 7 des Behälters 1 bis über den sich im Betrieb ausbildenden Suspensionsspiegel erstreckt. Diese Strömungsbarriere 8 reicht mit einem Radialvorsprung F in den Trog hinein, der mindestens 5 %, vorzugsweise mindestens 10 %, des Durchmessers D1 des Behälters 1 beträgt.At the rotor 2 opposite the inside of the
Zur Veranschaulichung zeigt die Fig. 2 den Stofflöser der Fig. 1 in Ansicht von oben. Dabei sind die Löcher des Siebblechs 6 nicht dargestellt.To illustrate, Fig. 2 shows the pulper of Fig. 1 in top view. The holes of the
Ein erfindungsgemäßer Stofflöser kann z.B. mit folgenden Maßen versehen sein. Der Behälter 1 dieses Stofflösers hat eine Gesamthöhe H von 2000 mm und eine zylindrische Seitenwand 5, deren Durchmesser D1 = 2435 mm beträgt. Die Exzentritzität E liegt bei einem Viertel des Durchmessers D1, also ca. 609 mm. Der Rotor 2 hat an seinen bewegten Flügeln einen Außendurchmesser D2 von 970 mm. Er läuft dicht über einem ebenen kreisringförmigen Sieb 6, dessen Öffnungen er von Verstopfungen frei hält. Der Boden 7 des Stofflösers ist mit einem Bodenwinkel α = 30° schräg gestellt, mit Ausnahme des horizontalen Siebbereiches. Auf der von der Mittellinie des Rotors 2 am meisten entfernten Seite der Seitenwand 5 ist eine Strömungsbarriere 8 angebracht, und zwar in Form eines rechtwinkeligen Winkelprofils, das sich vom Boden 7 bis etwa zum oberen Rand des Behälters 1 senkrecht erstreckt und mit einem Radialvorsprung F = 400 mm in den Behälter hineinragt. Auch wenn dieses Beispiel sich als besonders günstige Ausführungsform erwiesen hat, sind auch andere Fälle, insbesondere größere Stofflöser, vorstellbar, mit denen sich die Erfindung mindestens ebenso gut realisieren lässt.An inventive pulper may, for example, be provided with the following dimensions.
