Description

Die Erfindung betrifft ein Verfahren zum Gasbeheizen von Kalanderwalzen mittels einer Mehrzahl von nebenein­ander auf einem sich achsenparallel durch die Kalander­walze erstreckenden Gaszufuhrrohr angeordneten, auf die Innenfläche der zu beheizenden Kalanderwalze ausgerich­teten Gasdüsen, sowie eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for gas heating of calender rolls by means of a plurality of gas nozzles arranged side by side on a gas supply pipe which extends parallel to the axis through the calender roll and which are aligned with the inner surface of the calender roll to be heated, and a device for carrying out this process.

Es ist bekannt, zur Erreichung besonderer Effekte Tex­tilkalander mittels einer Gasheizung zu beheizen. Die Brenner werden dabei durch Gasdüsen gebildet, die ne­ beneinander auf einem sich achsenparallel durch die zu beheizende Kalanderwalze Gaszufuhrrohr erstrecken, wo­bei die Gasdüsen auf die Innenfläche der Kalanderwalze gerichtet sind.It is known to heat textile calenders by means of gas heating in order to achieve special effects. The burners are formed by gas nozzles, the ne extend side by side on a gas supply pipe parallel to the axis through the calender roll to be heated, the gas nozzles being directed towards the inner surface of the calender roll.

Die erreichte Temperatur auf der äußeren Oberfläche der Kalanderwalze ist dabei sowohl von der Menge der der Fläche der Kalanderwalze zugeführten als auch der Menge der von der Kalanderwalze durch Abstrahlung, insbeson­dere aber von der auf der Kalanderwalze aufliegenden Materialbahn abgeführten Energie abhängig.The temperature reached on the outer surface of the calender roller depends both on the amount of the energy supplied to the surface of the calender roller and on the amount of energy emitted by the calender roller by radiation, but in particular on the material web resting on the calender roller.

Es ist bekannt, daß Flammen in unterschiedlichen Zonen unterschiedliche Temperaturen aufweisen. Die Menge der auf eine Fläche übertragenen Wärmeenergie ist damit davon abhängig, in welcher Flammenzone diese Fläche angeordnet ist. Dies führt dazu, daß bei einer räumli­chen Anordnung der Gasdüse derart, daß bei einer mitt­leren Flammenhöhe eine optimale Wärmeenergieübertragung gegebenen ist, sowohl bei einer größeren Flammenlänge als auch bei geringerer Flammenlänge die Übertragung der Wärmeenergie suboptimal ist. Bei einer derartigen sub­optimalen Wärmeübertragung sind die auftretenden Ener­gieverluste erheblich, weiter erwärmt sich der Luftraum in der Kalanderwalze unnötig, was zu einer zusätzlichen thermischen Belastung der Walzenlagerungen führen kann.It is known that flames have different temperatures in different zones. The amount of thermal energy transferred to a surface is therefore dependent on the flame zone in which this surface is arranged. This leads to the fact that with a spatial arrangement of the gas nozzle in such a way that an optimal heat energy transfer is given at a medium flame height, the heat energy transfer is suboptimal both with a longer flame length and with a shorter flame length. With such a suboptimal heat transfer, the energy losses that occur are considerable, and the air space in the calender roll heats up unnecessarily, which can lead to an additional thermal load on the roll bearings.

Der Erfindung liegt damit die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, bei der ein optimaler Wärmeübergang zwischen Gasbrenner und der Kalanderwalze bei unterschiedlichen Flammhöhen gewähr­leistet ist.The invention is therefore based on the object of providing a method and a device in which an optimal heat transfer between the gas burner and the calender roll is ensured at different flame heights.

Erfindungsgemäß wird diese Aufgabe gelöst durch Anstel­len des die Gasdüsen tragenden Gaszufuhrrohres relativ zu der Innenfläche der Kalanderwalze in Abhängigkeit von der jeweiligen Flammenhöhe derart, daß der Abstand zwischen dem Gaszufuhrrohr und der Innenfläche der Kalanderwalze bei größerer flamme entsprechend vergrö­ßert wird.According to the invention, this object is achieved by positioning the gas supply pipe carrying the gas nozzles relative to the inner surface of the calender roll as a function of the respective flame height in such a way that the distance between the gas supply pipe and the inner surface of the calender roll is increased accordingly with a larger flame.

Vorzugsweise erfolgt das Anstellen des Gaszufuhrrohres relativ zu der Innenfläche der zu beheizenden Kalander­walze in Abhängigkeit von dem Druck des dem Gaszufuhr­rohr zugeführten Gas/Luft-Gemisches.The gas supply pipe is preferably turned on relative to the inner surface of the calender roll to be heated as a function of the pressure of the gas / air mixture supplied to the gas supply pipe.

Die entsprechende Vorrichtung zeichnet sich dadurch aus, daß das Gaszufuhrrohr beidseitig außerhalb der Kalanderwalze über elektromotorische Stellzylinder hö­henverstellbar aufgehängt ist.The corresponding device is characterized in that the gas supply pipe is suspended on both sides outside the calender roll by means of electromotive actuating cylinders.

Vorzugsweise ist ein über eine Signaleingangsleitung mit einem Temperaturregler und über Signalausgangslei­tungen mit den Stellylindern und mit Gleich/Verhältnis-­Druckreglern für die Gaszufuhr verbundenes, die Menge der dem Gaszufuhrrohr zugeführten Luft bestimmendes Motor-Luftregelventil vorgesehen.A motor air control valve, which determines the amount of air supplied to the gas supply pipe, is preferably provided via a signal input line with a temperature controller and via signal output lines with the Stellylinder and with equal / ratio pressure controllers for the gas supply.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der Beschreibung, in der ein Ausführungsbei­spiel der Erfindung anhand einer Zeichnung erläutert wird. Dabei zeigt:

  • Fig. 1 das Regelschema einer derartigen Vor­richtung, und
  • Fig. 2 eine schematische Darstellung der ver­schiedenen optimalen Positionen des Gas­zufuhrrohres relativ zu der Innenfläche der Kalanderwalze.
Further features and advantages of the invention result from the description in which an embodiment of the invention is explained with reference to a drawing. It shows:
  • Fig. 1 shows the control scheme of such a device, and
  • Fig. 2 is a schematic representation of the various optimal positions of the gas supply pipe relative to the inner surface of the calender roll.

Eine Gasleitung 22 versorgt zwei Gleich/Verhältnis-­Druckregler 16 von einem Gasanschluß 20 über einen Kugelhahn 24 mit Gas. Von den beiden Gleich/Verhältnis-­Druckreglern 16 wird das Gas sodann über mit einem Druckknopfhahn versehene Manometer 28 kontrolliert über Durchflußmesser 26 und Handabsperrventile 30 dem Gaszu­fuhrrohr 10 zugeführt.A gas line 22 supplies two direct / ratio pressure regulators 16 with gas from a gas connection 20 via a ball valve 24. From the two direct / ratio pressure regulators 16, the gas is then supplied to the gas supply pipe 10 in a controlled manner via a manometer 28 provided with a push-button tap, a flow meter 26 and manual shut-off valves 30.

Über eine Leitung 32 wird über ein Luftfilter 34 ange­saugte, in einem Verdichter 36 verdichtete Luft von einem mit einem Druckknopfhahn versehenen Manometer 38 kontrolliert einem mit einem Rückführpotentiometer versehenen Motor-Luftregelventil 18 zugeführt. Die durch das Motor-Luftregelventil 18 strömende Luft wird in zwei Zweige aufgeteilt, die jeweils mit einem Durch­flußmesser 40, einem Manometer mit Druckknopfhahn 42 und Regulierventilen 44, 46 versehen sind, wobei die Luft durch das Regulierventil 44 sich in dem Gaszufuhr­rohr 10 mit dem zugeführten Gas mischt und die Luft durch das Regulierventil 46 zu einer Sekundärluft-­Kammer 48 zwischen dem Gaszufuhrrohr 10 und den Bren­nerdüsen 50 geführt wird.Via a line 32, air which is sucked in and compressed in a compressor 36 is fed via an air filter 34 from a manometer 38 provided with a push-button valve to a motor air control valve 18 provided with a feedback potentiometer. The air flowing through the engine air control valve 18 is divided into two branches, each of which is provided with a flow meter 40, a pressure gauge with push-button valve 42 and regulating valves 44, 46, the air through the regulating valve 44 in the gas supply pipe 10 with the supplied Gas mixes and the air is passed through the regulating valve 46 to a secondary air chamber 48 between the gas supply pipe 10 and the burner nozzles 50.

Weiter ist eine elektrische Steuereinrichtung vorgese­hen, die aus zwei Temperaturautomaten 54, einem mit der Luftleitung 32 verbundenen Druckwächter 52, Zündtrans­formatoren 56 und einem mit einem Temperaturfühler 58 versehenen Temperaturregler 60 besteht.Furthermore, an electrical control device is provided, which consists of two automatic temperature devices 54, a pressure switch 52 connected to the air line 32, ignition transformers 56 and a temperature controller 60 provided with a temperature sensor 58.

Der Temperaturregler 60 wirkt über eine Signaleingangs­leitung 62 auf das mit einem Rückführpotentiometer versehene Motor-Luftregelventil 18. Dieses steuert über Signalausgangsleitungen 64 elektromotorische Stellzy­linder 12, an denen das Gaszufuhrrohr 10 aufgehängt ist. Weiter steuert das Motor-Regelventil 18 über Sig­nalausgangsleitungen 66 die die Gaszufuhr zu dem Gaszu­fuhrrohr 10 bestimmenden Gleich/Verhältnis-Druckregler 16.The temperature controller 60 acts via a signal input line 62 on the motor air control valve 18 which is provided with a feedback potentiometer. This controls via electric signal output lines 64 electromotive actuating cylinders 12, on which the gas supply pipe 10 is suspended. Furthermore, the engine control valve 18 controls the direct / ratio pressure regulator 16 determining the gas supply to the gas supply pipe 10 via signal output lines 66.

Von dem Motor-Luftregelventil 18 wird somit sowohl die Menge der Gaszufuhr zu dem Gaszufuhrrohr 10 als auch die Menge der dem Gaszufuhrrohr 10 zur Bildung eines Luft/Gas-Gemisches zugeführten Primärluft sowie die Menge der der Sekundärluftkammer 48 zugeführten Sekun­därluft geregelt. Weiter wird von dem Motor-Luftregel­ventil 18 aber auch die Anstellung des an den elektro­motorischen Stellzylindern 12 aufgehängten Gaszufuhr­rohres 10 relativ zu der - in Fig. 1 nicht gezeigten - Innenfläche der Kalanderwalze bestimmt.The engine air control valve 18 thus controls both the amount of gas supply to the gas supply pipe 10 and the amount of primary air supplied to the gas supply pipe 10 to form an air / gas mixture, as well as the amount of secondary air supplied to the secondary air chamber 48. Furthermore, the motor air control valve 18 also determines the position of the gas supply pipe 10 suspended from the electromotive actuating cylinders 12 relative to the inner surface of the calender roll (not shown in FIG. 1).

Die vorgeschlagene Ausbildung einer Gasheizung für Textilkalander ermöglicht es somit, das Gaszufuhrrohr mit den von ihm getragenen Gasdüsen jeweils so gegen­über der Innenfläche der Kalanderwalze anzustellen, daß - wie dies Fig. 2 schematisch zeigt - die Zone mit der höchsten Flammentemperatur an der Fläche anliegt, wo­durch eine optimale Wärmeübertragung gewährleistet ist. Bei einer größeren als mittleren Gaszufuhr wird dement­sprechend der Stellzylinder 12 über das Motor-Luftre­gelventil derart geregelt, daß das Gaszufuhrrohr 10 abgesenkt wird. Bei einer kleineren als mittleren Gas­zufuhr (und natürlich auch entsprechender kleinerer Luftzufuhr) wird das Gaszufuhrrohr entsprechend in eine Stellung angehoben, in der die relativ kleine Flamme mit ihrer heißesten Zone an der Innenfläche der Kalan­derwalze anliegt. Neben einem Verstellen in einer ver­tikalen Ebene könnte das Gaszufuhrrohr 10 natürlich auch in einer horizontalen Ebene entsprechend verstellt werden.The proposed design of a gas heater for textile calenders thus makes it possible to position the gas supply pipe with the gas nozzles carried by it against the inner surface of the calender roll in such a way that - as shown schematically in FIG. 2 - the zone with the highest flame temperature rests on the surface, which means that optimal heat transfer is guaranteed. With a larger than medium gas supply, the actuating cylinder 12 is accordingly regulated via the engine air control valve in such a way that the gas supply pipe 10 is lowered. With a smaller than medium gas supply (and of course also a correspondingly smaller air supply), the gas supply pipe is correspondingly into a Position raised in which the relatively small flame with its hottest zone lies against the inner surface of the calender roll. In addition to an adjustment in a vertical plane, the gas supply pipe 10 could of course also be adjusted accordingly in a horizontal plane.

In der Zeichnung sind weiter Schieber 68 angedeutet, die mittels Handkurbeln 70 der jeweiligen Breite der auf der Kalanderwalze aufliegenden Materialbahn ent­sprechend in das Gaszufuhrrohr 10 eingeschoben werden können, wodurch eine geeignete Temperatursteuerung im Bereich der Kanten der Materialbahn erreicht werden kann. Diese Ausgestaltung ist Gegenstand der gleichzei­tig eingereichten Patentanmeldung P 37 .. ... (Anwalts­akte RX 1607), wobei die Erfindung insbesondere in Verbindung mit der dort erläuterten Schieber/Gaszufuhr­rohr-Kombination von Vorteil ist. Dabei empfiehlt es sich dann, die Anstellung des Gaszufuhrrohres entspre­chend dem Neigungswinkel des Schiebers vorzunehmen.In the drawing, sliders 68 are also indicated, which can be pushed into the gas supply pipe 10 by means of hand cranks 70 in accordance with the respective width of the material web resting on the calender roll, as a result of which a suitable temperature control can be achieved in the region of the edges of the material web. This embodiment is the subject of the simultaneously filed patent application P 37 .. ... (attorney's file RX 1607), the invention being particularly advantageous in connection with the slide / gas supply pipe combination explained there. It is then advisable to adjust the gas supply pipe according to the angle of inclination of the slide.
