Description

Die Erfindung betrifft einen beheizten Zylinder zur Trocknung einer Faserstoffbahn, insbesondere einer Papier-, Karton-oder Tissuebahn in Maschinen zur Herstellung und/oder Veredelung derselben, bestehend aus einem Zylindermantel dessen äußere Mantelschicht eine gute Wärmeleitfähigkeit aufweist, wobei der äußeren Mantelschicht zur Heizung wenigstens ein außerhalb des Zylinders angeordnetes Heizsystem zugeordnet ist und sich innerhalb des Zylindermantels an die äußere Mantelschicht eine Wärme- Isolierschicht anschließt (siehe z.B. US 5 156 086 A).The invention relates to a heated cylinder for drying a fibrous web, in particular a paper, board or tissue web in machines for producing and / or refining thereof, comprising a cylinder jacket whose outer jacket layer has good thermal conductivity, wherein the outer jacket layer for heating at least one Assigned outside the cylinder arranged heating system and is connected within the cylinder jacket to the outer cladding layer, a heat insulating layer (see, for example, US 5,156,086 A).

Die Aufgabe der Erfindung ist es, bei diesem bekannter beheizten Zylinder die mit Heizsystem Profilierung der Feuchteverteilung quer zur Faserstoffbahn zu beeinflussen.The object of the invention is to influence in this known heated cylinder with heating system profiling the moisture distribution across the fibrous web.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.According to the invention this object is achieved by the characterizing features of claim 1.

Zur Verringerung der Aufwärm-und Abkühlzeiten sollte die vorzugsweise aus Metall bestehende äußere Mantelschicht möglichst dünn sein. Dies erhöht außerdem die maximale Temperaturdifferenz zwischen den verschiedenen Heizzonen.To reduce the warm-up and cool-down times, the outer metal layer, which is preferably made of metal, should be as thin as possible. This also increases the maximum temperature difference between the different heating zones.

Selbst für den Fall, daß die Formstabilität und Festigkeit des Zylinders noch wesentlich von der äußeren Mantelschicht mitbestimmt werden soll, ist anzustreben, daß die Dicke der äußeren Mantelschicht unter 30 mm, vorzugsweise unter 5 mm liegt.Even in the event that the dimensional stability and strength of the cylinder is still to be co-determined by the outer cladding layer, it is desirable that the thickness of the outer cladding layer is less than 30 mm, preferably less than 5 mm.

Falls jedoch die Formstabilität und Festigkeit des Zylinders im wesentlichen von der Isolierschicht und/oder einer sich innerhalb des Zylindermantels an die Isolierschicht anschließender Tragstruktur bestimmt wird, so ist es von Vorteil, wenn die äußere Mantelschicht eine Dicke von weniger als 5 mm, vorzugsweise weniger als 1 mm und insbesondere von weniger als 0,2 mm aufweist.However, if the dimensional stability and strength of the cylinder is substantially determined by the insulating layer and / or a supporting structure adjacent to the insulating layer within the cylinder jacket, it is advantageous if the outer jacket layer has a thickness of less than 5 mm, preferably less than 1 mm and in particular less than 0.2 mm.

Die Tragstruktur kann dabei aus Metall bestehen, wobei jedoch die thermische Wirkung einer Induktionsheizung zu beachten ist.The support structure may be made of metal, but the thermal effect of an induction heating is to be considered.

Leichtere Zylinder ergeben sich jedoch im allgemeinen, wenn die tragende Isolierschicht und/oder die Tragstruktur aus einem faserverstärkten, thermisch isolierenden Kunststoff bestehen. Dies bedeutet, daß diese Isolierschicht und die Tragstruktur auch ein einziges, gegebenenfalls strukturiertes oder mehrschichtiges Element des Zylindermantels bilden können.However, lighter cylinders generally result when the supporting insulating layer and / or the supporting structure are made of a fiber-reinforced thermally insulating plastic. This means that this insulating layer and the support structure can also form a single, possibly structured or multilayered element of the cylinder jacket.

Unter Umständen können sich auch Vorteile hinsichtlich der Stabilität und Festigkeit oder der Fertigung ergeben, wenn die Isolierschicht und/oder die Tragstruktur zumindest einen wesentlichen Teil, vorzugsweise den ganzen Innenraum des Zylinders ausfüllen.Under certain circumstances, there may also be advantages in terms of stability and strength or manufacturing, if the insulating layer and / or the support structure at least a substantial part, preferably fill the entire interior of the cylinder.

Der Durchmesser des Zylinders bestimmt einerseits die zu erwärmende Manteloberfläche, was den maximalen Durchmesser begrenzt, und hat andererseits jedoch auch Einfluß auf die Kontaktzeit mit der Faserstoffbahn, wodurch sich ein Minimum ergibt. Besonders gute Ergebnisse wurden mit Zylindern, deren Durchmesser im Bereich von 500 bis 3000 mm, vorzugsweise zwischen 1200 und 1800 mm liegt, erreicht.The diameter of the cylinder on the one hand determines the jacket surface to be heated, which limits the maximum diameter, and on the other hand, however, also has an influence on the contact time with the fibrous web, resulting in a minimum. Particularly good results have been achieved with cylinders whose diameter is in the range of 500 to 3000 mm, preferably between 1200 and 1800 mm.

Die optimale Zonenbreite wird vom Aufwand für das Heizsystem und vom Wärmefluß zwischen den Heizzonen bestimmt. Gute Ergebnisse sind bei Zonenbreiten im Bereich von 30 bis 100 mm, vorzugsweise im Bereich zwischen 40 und 75 mm realisierbar.The optimal zone width is determined by the cost of the heating system and the heat flow between the heating zones. Good results are achievable at zone widths in the range of 30 to 100 mm, preferably in the range between 40 and 75 mm.

In diesem Zusammenhang läßt sich der Wärmestrom zwischen den Heizzonen noch dadurch verringern, daß die äußere Mantelschicht im Bereich zwischen den Heizzonen eine verringerte Dicke besitzt. Dies kann auf einfache Weise über eine schmale, vorzugsweise außen verlaufende und die Qualität der Faserstoffbahn nicht beeinträchtigende Umfangsrille erfolgen.In this context, the heat flow between the heating zones can be further reduced by the fact that the outer cladding layer in the region between the heating zones has a reduced thickness. This can be done in a simple manner via a narrow, preferably outwardly extending and not impairing the quality of the fibrous web circumferential groove.

Zur effizienten Beeinflussung der Feuchteverteilung oder Trocknung der Faserstoffbahn insgesamt und unter Vermeidung von Hitzeschäden an der Faserstoffbahnoberfläche sollte die maximale Oberflächentemperatur des Zylinders zwischen 120 und 250 °C, vorzugsweise zwischen 150 und 200 °C liegen. Hierzu ist es meist erforderlich, daß die gesamte, verfügbare Heizleistung bis zu einem Zylinderdurchmesser von 1200 mm mindestens 60 kW/m, bei einem Zylinderdurchmesser zwischen 1200 und 1800 mm mindestens 80 kW/m und bei einem Zylinderdurchmesser von mehr als 1800 mm mindestens 120 KW/m beträgt.For efficient influencing of the moisture distribution or drying of the fibrous web as a whole and avoiding heat damage to the fibrous web surface, the maximum surface temperature of the cylinder should be between 120 and 250 ° C, preferably between 150 and 200 ° C. For this it is usually necessary that the total available heating power up to a cylinder diameter of 1200 mm at least 60 kW / m, with a cylinder diameter between 1200 and 1800 mm at least 80 kW / m and with a cylinder diameter of more than 1800 mm at least 120 KW / m is.

Außerdem sollte zur Gewährleistung eines ausreichenden Wärmeflusses zur Faserstoffbahn die Kontaktzeit des Zylinders mit der Faserstoffbahn mindestens 50 ms, vorzugsweise mindestens 80 ms und insbesondere mindestens 120 ms betragen.In addition, to ensure sufficient heat flow to the fibrous web, the contact time of the cylinder with the fibrous web should be at least 50 ms, preferably at least 80 ms and in particular at least 120 ms.

Nachfolgend soll Erfindung an mehreren Ausführungsbeispielen näher erläutert werden. In der beigefügten Zeichnung zeigt:

  • Figur 1: einen schematischen Querschnitt eines Zylinders 1 mit tragender Isolierschicht 5;
  • Figur 2: einen schematischen Querschnitt eines Zylinders 1 mit Isolierschicht 5 und Tragstruktur 6 und
  • Figur 3: eine schematische Draufsicht eines Zylinders 1.
The invention will be explained in more detail below with reference to several exemplary embodiments. In the attached drawing shows:
  • Figure 1: a schematic cross section of a cylinder 1 with a supporting insulating layer 5;
  • Figure 2: a schematic cross section of a cylinder 1 with insulating layer 5 and support structure 6 and
  • FIG. 3 shows a schematic top view of a cylinder 1.

Alle beheizten Zylinder 1 bestehen hier aus einem Zylindermantel dessen äußere, metallische Mantelschicht 3 eine gute Wärmeleitfähigkeit aufweist. Außerdem ist dieser Mantelschicht 3 ein außerhalb des Zylinders 1 angeordnetes, induktives Heizsystem 4 zugeordnet. Zur Begrenzung des Wärmeflusses schließt sich innerhalb des Zylindermantels an die äußere Mantelschicht 3 eine Wärme-Isolierschicht 5 an.All heated cylinders 1 here consist of a cylinder jacket whose outer metallic cladding layer 3 has a good thermal conductivity. In addition, this jacket layer 3 is assigned an outside of the cylinder 1, inductive heating system 4. To limit the heat flow, a heat insulating layer 5 adjoins the outer jacket layer 3 within the cylinder jacket.

In Figur 1 wird die Formstabilität und Festigkeit des Zylinders 1 von der äußeren Mantelschicht 3, die beispielhaft eine Dicke von 4 mm aufweist und der ebenfalls tragenden Isolierschicht 5 gewährleistet. Dies vereinfacht den Aufbau, wobei die Isolierschicht 5 aus faserverstärktem Kunststoff besteht. Die Herstellung des Zylinders 1 erfolgt durch thermisches Aufschrumpfen der metallischen Mantelschicht 3 auf die Isolierschicht 5.In Figure 1, the dimensional stability and strength of the cylinder 1 of the outer cladding layer 3, which has a thickness of 4 mm, for example, and the insulating layer 5 also carries. This simplifies the structure, wherein the insulating layer 5 consists of fiber-reinforced plastic. The production of the cylinder 1 is carried out by thermal shrinkage of the metallic shell layer 3 on the insulating layer. 5

Im Gegensatz hierzu hat die äußere Mantelschicht 3 in Figur 2 kaum noch eine tragende Funktion und kann daher auf eine Dicke von weniger als 1 mm beschränkt werden. Dies verringert den Wärmefluß entlang des Zylinders 1, so daß größere Temperaturunterschiede an der Manteloberfläche eingestellt werden können.In contrast, the outer cladding layer 3 in Figure 2 hardly has a supporting function and can therefore be limited to a thickness of less than 1 mm. This reduces the heat flow along the cylinder 1, so that larger Temperature differences on the mantle surface can be adjusted.

Die Isolierschicht 3 besteht aus einem Kunststoff geringster Wärmeleitfähigkeit und eine sich innerhalb des Zylindermantels daran anschließende Tragstruktur 6 aus einem faserverstärkten Kunststoff, wobei die Tragstruktur 6 einen großen Teil des Inneren des Zylinders 1 ausfüllt. Dies ermöglicht eine leichte und sehr stabile Tragstruktur 6.The insulating layer 3 consists of a plastic least thermal conductivity and an adjoining within the cylinder jacket support structure 6 made of a fiber-reinforced plastic, wherein the support structure 6 fills a large part of the interior of the cylinder 1. This allows a lightweight and very stable support structure. 6

Die Zylinder 1 haben ebenfalls beispielhaft einen Durchmesser von 1500 mm, wobei sich durch die Führung der Faserstoffbahn 2 eine Kontaktzeit von 120 ms ergibt.The cylinders 1 also have, by way of example, a diameter of 1500 mm, with a contact time of 120 ms resulting from the guidance of the fibrous web 2.

Das Heizsystem 4 ist entlang des Zylinders 1 in mehrere separat steuerbare Heizzonen 7 unterteilt, wobei die Zonenbreite 50 mm beträgt. Bei einer verfügbaren Heizleistung von 100 kW/m sind Oberflächentemperaturen des Zylinders 1 von ca. 200 °C erreichbar.The heating system 4 is divided along the cylinder 1 into a plurality of separately controllable heating zones 7, wherein the zone width is 50 mm. With an available heat output of 100 kW / m surface temperatures of the cylinder 1 of about 200 ° C can be reached.

Um den Wärmefluß zwischen den Heizzonen 7 zu beschränken, ist die Dicke der äußeren Mantelschicht 3 zwischen den Heizzonen 7 verringert. Dies erfolgt über eine sehr schmale, von außen mit einem Laser eingebrannte Umfangsrille 8. Dies verbessert die Unabhängigkeit der Heizzonen 7.In order to restrict the heat flow between the heating zones 7, the thickness of the outer jacket layer 3 between the heating zones 7 is reduced. This is done via a very narrow, burned from the outside with a laser circumferential groove 8. This improves the independence of the heating zones. 7
