Description
Die Erfindung betrifft einen kapazitiven Hochfrequenzofen zum Trocknen von gefalteten Chemiefaserkabeln, bei dem die Faserpakete zwischen mindestens zwei Elektroden unterschiedlichen Potentials auf einem Förderband transportierbar sind und die eine Elektrode von einem mit der G-"ichwindigkeit des Förderbandes laufenden zusätzlichen Band umpeben i=tThe invention relates to a capacitive high-frequency oven for drying folded man-made fiber cables, in which the fiber packages between at least two electrodes of different potential on one Conveyor belt are transportable and the one electrode of one with the G-speed of the conveyor belt umpeben running additional tape i = t
Mit diesem Gattungsbegriff wird von einer Anordnung ausgegangen, wie sie beispielsweise in der DE-PS 8 33 987 beschrieben ist.This generic term is based on an arrangement such as that in DE-PS 8 33 987 is described.
Bei der Trocknung und Fixierung von gefalteten Chemiefaserkabeln im kapazitiven Hochfrequenzofen hat es sich herausgestellt, daß im Faserpaket unzulässig hohe Temperaturunterschiede auftreten können. Diese Unterschiede sind um so größen je höher die Fixiertemperatur gewählt wird. Die Unterschiede beruhen im wesentlichen darauf, daß die Faserpakete die Eigenschaft aufweisen, bei Beginn der Hochfrequenztrocknung infolge des bestehenden Dampfdrukkes aufzuspringen, so daß die homogene Dichte des Faserpaketes gestört wird.When drying and fixing folded man-made fiber cables in a capacitive high-frequency oven it has been found that inadmissibly high temperature differences can occur in the fiber package. These The higher the fixing temperature, the greater the differences. The differences are based essentially on the fact that the fiber packets have the property at the start of high-frequency drying to jump open as a result of the existing steam pressure, so that the homogeneous density of the Fiber packet is disturbed.
Es besteht jedoch für bestimmte Fasertypen die Forderung. Fixiertemperaturen zwischen 200 und 250° einzustellen, wobei die Temperaturschwankungen im Faserpaket nicht größer als ± 5° sein dürfen, um keine Schwankungen der Faserquwlität zu verursachen.However, there is a requirement for certain types of fibers. Fixing temperatures between 200 and 250 ° set, whereby the temperature fluctuations in the fiber package must not be greater than ± 5 ° in order to avoid any To cause fluctuations in the fiber quality.
Die Aufgabe der vorliegenden Eründung besteht darin, den Hochfrequenzofen so auszubilden, daß sich eine annähernd gleichmäßige Temperaturverteilung im Faserpaket ergibt.The task of the present explanation is in designing the high-frequency furnace so that there is an approximately uniform temperature distribution in the Fiber package results.
Diese Aufgabe wird erfindungsgemäß bei einem Ofen der eingangs genannten Art dadurch gelöst, daß das als geerdete Elektrode dienende Förderband und die andere Elektrode beheizbar sind und daß die andereThis object is achieved according to the invention in a furnace of the type mentioned in that the as grounded electrode serving conveyor belt and the other electrode are heated and that the other
ίο Elektrode in Verbindung mit dem zusätzlichen Band auf die Faserpakete drückt.ίο Electrode in connection with the additional tape pushes the fiber packets.
Durch den Druck der Elektroden bleibt die Homogenität des Paketes gewahrt, gleichzeitig wird aber durch die Beheizung der Elektroden vermieden.The homogeneity of the package is maintained by the pressure of the electrodes, at the same time but avoided by heating the electrodes.
is daß die Druckstellen zu stark gekühlt werden. Die Behe.zung ist ferner deshalb besonders wichtig, da die Fasern an den Druckstellen (Faltstellen) infolge ihrer Lage zum elektrischen Feld schon von vornherein geringer als der Rest erwärmt werden. Der Druck deris that the pressure points are cooled too much. the Treatment is also particularly important because the fibers at the pressure points (folds) as a result of their Position relative to the electric field can be heated less than the rest from the outset. The pressure of the
oberen Elektrode bzw. des oberen zusätzlichen Bandes ist vorteilhaft derart einstellbar, daß er in Laufrichtung ansteigen oder abfallen kann. Ebenso können die Elektroden vorteilhafterweise auch so ausgebildet sein, daß der Druckwert quer zur Förderrichtung beeinflußbar ist.upper electrode or the upper additional band is advantageously adjustable in such a way that it runs in the direction of travel can rise or fall. Likewise, the electrodes can advantageously also be designed in such a way that that the pressure value can be influenced transversely to the conveying direction.
Das zusätzliche Band kann auch ggf. selbst als beheizbare Elektrode dienen, wenn es aus Me'.all ist.The additional tape can also serve as a heatable electrode itself if it is made of Me'.all.
Anhand einer Zeichnung wird die Erfindung näher erläutert: Die vom nichtgezeigten Krimper auf einemThe invention is explained in more detail with the aid of a drawing: The Krimper, not shown, on a
3U Förderband 8 antransportierten Faserpakete 7 gelangen auf ein in RichUng des Pfeiles 10 laufendes, geerdetes Förderband 3, welches über geerdete Rollen 6 läuft und selbst als beheizbare Elektrode dient. Oberhalb der Faserpakete 7 ist im Hochfrequenzofen 1 eine an 3U conveyor belt 8 transported fiber packets 7 arrive at a grounded conveyor belt 3 running in the direction of arrow 10, which runs over grounded rollers 6 and itself serves as a heatable electrode. Above the fiber packets 7 there is an on in the high-frequency furnace 1
Hochspannung liegende beheizbare Elektrode 4 vorgesehen, welche über einen Regelkondensator 9 an die Hochspannung des Hochfrequenzgenerators 2 angeschlossen ist. Die obere Elektrode 4 ist von einem ebenfalls in Richtung des Pfeiles 10 !aufrunden Band 11 umgeben, welches über Rollen 5 läuft. Dieses obere Band wirkt in Verbindung mit der Elektrode 4 gleichzeitig als Niederhaltung für die Faserpakete 7 und als Durchlaufpresse mit einstellbarem Druck. Durch das sich zwischen den Elektroden 3 und 4 ausbildende elektrische Feld und den dadurch entstehenden Dampf wird in den zusammengedrückten Faserkabeln in sehr kurzer Zeit (einige set) eine gleichmäßge Erwärmung erreicht. Auf diese Weise lassen sich verschiedene Textilwerte der behandelten Fasern verbessern. /. B.Heatable electrode 4 lying at high voltage is provided, which is connected to the high voltage of the high frequency generator 2 via a regulating capacitor 9 is. The upper electrode 4 is made of a band 11 which is also rounded up in the direction of the arrow 10! surrounded, which runs over rollers 5. This upper band works in conjunction with the electrode 4 at the same time as a hold-down for the fiber packages 7 and as a continuous press with adjustable pressure. By the electric field developing between electrodes 3 and 4 and the resulting vapor the compressed fiber cables heat up evenly in a very short time (some sets) achieved. In this way, various textile values of the treated fibers can be improved. /. B.
