Description

Die Erfindung betrifft einen Refiner zur Zerfaserung von lignozellulosehaltigen Materialien mit mindestens einer rotierenden Refinerscheibe und einem Refinergehäuse, wobei das Refinergehäuse einen Faserauslass, eine Frischdampfzuleitung und eine Einrichtung zur Kontrolle des Druckes und der Faserabströmung aufweist.The invention relates to a refiner for defibrating lignocellulose-containing materials with at least one rotating refiner disc and a refiner housing, wherein the refiner housing has a fiber outlet, a live steam supply line and a device for controlling the pressure and the fiber outflow.

Derartige Refiner sind z.B. aus der WO 83/02788 bekannt, in der lignozellulosehaftige Materialien mittels einer rotierenden und einer stationären Refinerscheibe zerfasert werden und das Refinergehäuse eine Frischdampfzuleitung sowie einen Faserauslass und ein Blasventil zur Kontrolle von Druck und Faserabströmung aufweist. Ein anderer Refiner ist aus der WO 2006/112769 bekannt. Die mechanische Zerfaserung des Materials, meist Hackschnitzel, erfordert Energie, die durch die Refinersegmente auf den Refinerscheiben eingebracht wird. Diese Energie wird in Wärme umgesetzt, wodurch das im Material enthaltene Wasser verdampft und im Refinergehäuse einen Druck erzeugt. Der Großteil des Dampfes wird gemeinsam mit den erzeugten Fasern aus dem Refinergehäuse ausgetragen. Bei der Faser herstellung aus lignozellulosehaltigen Materialien, insbesondere für die Holzwerkstoffindustrie, z.B. für MDF Platten, werden Refiner eingesetzt, bei denen die ausströmende Dampfmenge aus dem Refiner mit Hilfe eines Blasventils kontrolliert wird.Such refiner are eg from the WO 83/02788 known in the Lignozellulosehaftige materials are shredded by means of a rotating and a stationary Refinerscheibe and the Refinergehäuse has a live steam supply line and a fiber outlet and a blow valve for controlling pressure and Faserabströmung. Another refiner is from the WO 2006/112769 known. The mechanical defibration of the material, usually wood chips, requires energy, which is introduced through the refiner segments on the refiner discs. This energy is converted into heat, which evaporates the water contained in the material and creates pressure in the refiner housing. The majority of the steam is discharged from the refiner housing together with the fibers produced. In the manufacture of fiber from lignocellulosic materials, especially for the wood-based industry, eg for MDF boards, refiners are used in which the outflowing amount of steam from the refiner is controlled by means of a blow valve.

Mit der ausströmenden Dampfmenge wird gleichzeitig die erzeugte Faser in die nachfolgenden Prozesse über eine Rohrleitung (Blasleitung) transportiert. Das Blasventil ist direkt am Faserauslass des Refiners oder nach einem kurzen Rohrstück nach dem Refiner in der Blasleitung angebracht und wird so betrieben, dass die durch das Blasventil abströmende Dampfmenge so eingestellt ist, dass die über ein Frischdampfventil am Refinergehäuse zugeführte Frischdampfmenge so gering wie möglich gehalten werden kann. Durch das ständig abströmende Dampf/Fasergemisch ist eine entsprechende Frischdampfzufuhr erforderlich, um den Druck im Refinergehäuse konstant zu halten. Hier ist die minimale Dampfabfuhr und damit auch die anschließend erforderliche Frischdampfzufuhr durch den Faseranteil beschränkt, der gesamt abgeführt werden muss. Durch die Rotation der Refinerscheibe werden die erzeugten Fasern im Gehäuse herumgeschleudert, wodurch der Energieverbrauch erhöht wird. Auch besteht die Gefahr, dass die Fasern zusammenbacken und somit den Faserstrom bzw. die gesamte Abströmung des Dampf-Fasergemisches blockieren, was wiederum zu einem höheren Energieverbrauch führt.With the outflowing amount of steam at the same time the fiber produced is transported in the subsequent processes via a pipe (blowing line). The blow valve is mounted directly on the fiber outlet of the refiner or after a short piece of pipe after the refiner in the blowpipe and is operated so that the amount of steam flowing through the blow valve is adjusted so that kept by a live steam valve on the refiner housing supplied amount of fresh steam as low as possible can be. Due to the constantly flowing steam / fiber mixture a corresponding live steam supply is required to keep the pressure in the refiner housing constant. Here, the minimum steam removal and thus the subsequently required live steam supply is limited by the fiber content, which must be dissipated. Due to the rotation of the refiner disc, the generated fibers are thrown around in the housing, which increases the energy consumption. There is also the risk that the fibers cake together and thus block the fiber flow or the entire outflow of the steam-fiber mixture, which in turn leads to a higher energy consumption.

Ziel der Erfindung ist es daher eine weitere Reduktion von Frischdampf und Energieeinsparung unabhängig von der abströmenden Fasermenge zu erreichen.The aim of the invention is therefore to achieve a further reduction of live steam and energy savings regardless of the amount of fiber flowing out.

Die Erfindung ist daher dadurch gekennzeichnet, dass der Faserauslass ein tangentialer Faserauslass ist und dass im Refinergehäuse im Bereich des Stutzens für den Faserauslass eine Ventilklappe vorgesehen ist. Durch diese Ventilklappe erfolgt eine Trennung des Dampf/Fasergemisches derart, dass nur Dampf abgeschieden wird, der am intensivsten mit Fasern durchmengt ist. Der weitestgehend faserfreie Dampfanteil verbleibt im Refiner, wodurch etwa diese Menge an Frischdampf gegenüber den bisherigen Systemen eingespart werden kann.The invention is therefore characterized in that the fiber outlet is a tangential fiber outlet and that a valve flap is provided in the refiner housing in the area of the nozzle for the fiber outlet. Through this valve flap, a separation of the vapor / fiber mixture is such that only steam is deposited, which is durchmengt most intensively with fibers. The largely fiber-free vapor content remains in the refiner, whereby about this amount of live steam over the previous systems can be saved.

Eine vorteilhafte Weiterbildung der Erfindung ist dadurch gekennzeichnet, dass die Ventilklappe zwischen einer Position offen und zu verstellbar ist. Damit kann auch die Verweilzeit der Fasern im Refiner und damit die Qualität der Zerfaserung kontrolliert werden. Weiters lässt sich die ausströmende Dampfmenge damit gut regeln.An advantageous development of the invention is characterized in that the valve flap is open and adjustable between a position. Thus, the residence time of the fibers in the refiner and thus the quality of the defibration can be controlled. Furthermore, the outflowing amount of steam can thus be regulated well.

Eine günstige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die Ventilklappe mit einem außen am Refiner montierten Antrieb verbunden ist, wobei der Antrieb ein selbsthemmender Spindelantrieb sein kann. Mit dieser Ausführung lässt sich die Verstellung der Ventilklappe gut während des Betriebs durchführen.A favorable embodiment of the invention is characterized in that the valve flap is connected to a drive mounted outside the refiner, wherein the drive can be a self-locking spindle drive. With this design, the adjustment of the valve flap can be carried out well during operation.

Die Erfindung wird nun anhand der Zeichnungen beispielhaft beschrieben, wobei

  • Fig. 1 die 3 D-Ansicht eines erfindungsgemäßen Refiners mit Antrieb,
  • Fig. 2 eine Ansicht auf die Stirnseite eines erfindungsgemäßen Refiners,
  • Fig. 3 einen Schnitt durch einen erfindungsgemäßen Refiner,
  • Fig. 4 die Funktionsweise eines erfindungsgemäßen Refiners und
  • Fig. 5 einen Ausschnitt eines erfindungsgemäßen Refiners im Bereich der Ventilklappe darstellt.
The invention will now be described by way of example with reference to the drawings, in which:
  • Fig. 1 3 D view of a refiner according to the invention with drive,
  • Fig. 2 a view of the front side of a refiner according to the invention,
  • Fig. 3 a section through a refiner according to the invention,
  • Fig. 4 the operation of a refiner according to the invention and
  • Fig. 5 represents a section of a refiner according to the invention in the region of the valve flap.

Fig. 1 zeigt eine 3 D Ansicht eines erfindungsgemäßen Refiners 1 mit Refinergehäuse 2 und einem tangentialen Refinerauslass 3. Das Refinergehäuse 2 weist eine schwenkbare Refinertüre 4 und eine Frischdampfzufuhrleitung 5 auf. In Fig. 1 ist weiters der Antrieb 6 (Motor) des Refiners 1 dargestellt. Fig. 1 shows a 3 D view of a refiner 1 according to the invention with Refinergehäuse 2 and a tangential Refinerauslass 3. The Refinergehäuse 2 has a pivotable Refinertüre 4 and a live steam supply line 5. In Fig. 1 Furthermore, the drive 6 (motor) of the refiner 1 is shown.

In Fig. 2 ist eine Frontalansicht auf einen erfindungsgemäßen Refiner 1 dargestellt. Neben dem tangential angeordneten Faserauslass 3 und der Refinertüre 4 kann man hier den Stellantrieb 7 für das Regelventil und den Antrieb 8, der hier als selbsthemmender Spindelantrieb ausgeführt ist, erkennen. Natürlich können auch andere Regelantriebe eingesetzt werden.In Fig. 2 is a frontal view of a refiner 1 according to the invention shown. In addition to the tangentially arranged fiber outlet 3 and the Refinertüre 4 can here the actuator 7 for the control valve and the drive 8, which is designed here as a self-locking spindle drive, recognize. Of course, other variable speed drives can be used.

Fig. 3 zeigt einen Schnitt durch ein erfindungsgemäßes Refinergehäuse 2 mit dem tangentialen Faserauslass 3. Um die Refinerscheibe 9 herum ist ein Ringraum 10 angeordnet, durch den das Dampf/Fasergemisch strömt. Im Bereich des Stutzens für den Faserauslass 3 befindet sich die Ventilklappe 11 (hier in der Position "ganz offen"). Die Ventilklappe befindet sich am Ende eines Umlenkrings 12. Fig. 3 shows a section through a refiner housing 2 according to the invention with the tangential fiber outlet 3. Around the refining disc 9 around is an annular space 10 arranged, through which the steam / fiber mixture flows. In the area of the nozzle for the fiber outlet 3 is the valve flap 11 (here in the position "completely open"). The valve flap is located at the end of a deflection ring 12.

Fig. 4 stellt einen vergrößerten Ausschnitt (etwa ¼ Kreis) des Refiners dar, wobei hier auch die Strömungen des Dampf/Fasergemisches gezeigt werden. Das im Refiner gebildete Dampf/Fasergemisch 13 befindet sich am oberen rechten Bildeck im Ringraum 10 und rotiert durch die Drehbewegung des Rotors im Druckgehäuse mit einer gewissen Geschwindigkeit (hier gegen den Uhrzeigersinn). Durch die Ventilklappe 11 wird dieses Dampf/Fasergemisch 13 praktisch wie mit einem Messer oder Schaber in einen Teil 14, der durch den Faserauslass 3 aus dem Refiner 1 austritt und einen Teil 15, der im Refinerdruckgehäuse 2 (im Ringraum 10) verbleibt geteilt. Durch diese Trennung von Faser und Dampf ergibt sich die Möglichkeit einen nahezu faserfreien Dampf eher im Refiner zu belassen, wobei nur der Dampf abgeschieden wird, der am intensivsten mit Fasern durchmengt ist. Der Refiner wird somit zusätzlich zur Zerfaserung auch wie eine Faserzentrifuge zur Faser/Dampftrennung genutzt. Dadurch ergibt sich eine erhebliche Einsparung an Frischdampf, da nicht wie bisher der gesamte Dampf abgeführt wird. Durch die wesentlich höhere Faserkonzentration in der Blasleitung reduziert sich auch der Bedarf an Leim bei der nachgeschalteten Beleimung in der Blasleitung. Fig. 4 represents an enlarged section (approximately ¼ circle) of the refiner, whereby the flows of the vapor / fiber mixture are also shown here. The steam / fiber mixture 13 formed in the refiner is located on the upper right Bildeck in the annular space 10 and rotated by the rotational movement of the rotor in the pressure housing with a certain speed (here counterclockwise). By means of the valve flap 11, this steam / fiber mixture 13 is divided practically like a knife or scraper into a part 14 which exits the refiner 1 through the fiber outlet 3 and a part 15 which remains in the refiner pressure housing 2 (in the annular space 10). Due to this separation of fiber and steam, it is possible to leave a nearly fiber-free vapor in the refiner, whereby only the vapor which is intensively mixed with fibers is separated. The refiner is thus used in addition to the fiberization as a fiber centrifuge for fiber / vapor separation. This results in a significant saving in live steam, since not as before, the entire steam is dissipated. Due to the much higher fiber concentration in the blowpipe also reduces the need for glue in the downstream gluing in the blowpipe.

Fig. 5 zeigt einen Ausschnitt im Bereich der Ventilklappe 11 Man erkennt neben der Refinerscheibe 9, dem Ringraum 10, dem Umlenkring 12 und dem tangentialen Faserauslass 3 auch die Ventilklappe 11 in einer üblichen Betriebsposition. Die Ventilklappe 11 ist um eine Achse 16, die mit dem Stellantrieb 7 verbunden ist, über einen Winkelbereich 19 drehbar. Bei der Position ganz zu" (17) der Ventilklappe 11 wird das gesamte Dampf/Fasergemisch in den Ringraum 10 umgeleitet, was insbesondere beim Anfahrvorgang von Vorteil ist. Bei der Position "ganz offen" (18) der Ventilklappe 11 bleibt zwischen der Ventilklappe und der Refinerscheibe 9 ein kleiner Spalt, wobei die Ventilklappe 11 in Verlängerung des Faserauslasses 3 eingestellt ist und somit den gesamten Anströmquerschnitt desselben freigibt. Durch das Verschwenken der Ventilklappe 11 um die Achse 16 lässt sich immer ein optimaler Betriebspunkt für die Faserabgabe und Frischdampfbedarf einstellen. Fig. 5 shows a section in the region of the valve flap 11 It can be seen next to the refiner disc 9, the annular space 10, the deflection ring 12 and the tangential fiber outlet 3 and the valve flap 11 in a normal operating position. The valve flap 11 is rotatable about an axis 16, which is connected to the actuator 7, over an angular range 19. In the position entirely to (17) of the valve flap 11, the entire steam / fiber mixture is diverted into the annular space 10, which is particularly advantageous during the start-up procedure the refining disc 9 is a small gap, wherein the valve flap 11 is set in extension of the fiber outlet 3 and thus the entire flow cross section of the same releases .. By pivoting the valve flap 11 about the axis 16 can always set an optimal operating point for the fiber delivery and live steam.
