Description

Kapazitiver Hochfrequenzofen zum Trocknen von gefalteten ChemiefaserkabelnCapacitive high frequency oven for drying folded man-made fiber cables

Die Erfindung "betrifft einen kapazitiven Hochfrequenzofen zum Trocknen von gefalteten Chemiefaserkabeln, hei dem die Faserpakete zwischen mindestens zwei Elektroden unterschiedlichen Potentials auf einem Förderband transportierbar sind, welches die eine Elektrode bildet.The invention "relates to a capacitive high frequency furnace for Drying of folded man-made fiber cables, i.e. the fiber packages can be transported on a conveyor belt between at least two electrodes of different potential, which which forms an electrode.

Bei der Trocknung und Fixierung von gefalteten Chemiefaserkabeln im kapazitiven Hochfrequenzofen (z.B. nach der holländischen Patentanmeldung 67 10 719) hat es sich herausgestellt, daß im Faserpaket unzulässig hohe Temperaturunterschiede auftreten können. Diese Unterschiede sind um so größer, 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 Dampfdruckes aufzuspringen, so daß die homogene Dichte des Faserpaketes gestört wird.When drying and fixing folded man-made fiber cables in the capacitive high frequency furnace (e.g. according to the Dutch patent application 67 10 719) it has been found that in the Fiber package inadmissibly high temperature differences can occur. The greater the differences, the greater the differences Fixing temperature is selected. The differences are based essentially on the fact that the fiber packages have the property at the start of high-frequency drying as a result of the existing To jump up vapor pressure, so that the homogeneous density of the fiber package is disturbed.

Es besteht jedoch für bestimmte Fasertypen die Forderung, Fixiertemperaturen zwiochen 200 und 250° einzustellen, wobei die Temperaturschwankungen im Faserpaket nicht größer als _+ 5° sein ^ dürfen, um keine Schwankungen der Faserqualität zu verursachen.For certain types of fibers, however, there is a requirement for fixing temperatures set between 200 and 250 °, the temperature fluctuations in the fiber package not being greater than _ + 5 ° ^ in order not to cause any fluctuations in the fiber quality.

Die Aufgabe der vorliegenden Erfindung "besteht darin, den Hochfrequenzofen so auszubilden, daß während des Trocknungsprozesses die Homogenität der Faserpakete erhalten bleibt, und daß somit eine annähernd gleichmäßige Temperaturvsrteilung im Faserpaket erreicht wird.The object of the present invention "is to provide the Train high-frequency furnace so that the homogeneity of the fiber packages is maintained during the drying process, and that thus an approximately uniform temperature distribution in the Fiber package is achieved.

Diese Aufgabe wird erfindungsgemäß bei einem Ofen der eingangs genannten Art dadurch gelöst, daß die heiße Elektrode von einem mit der Geschwindigkeit des Förderbandes laufenden Band umgeben ist, und daß das zusätzliche Band auf die Faserpakete gedrückt ist.This object is achieved according to the invention in a furnace of the type mentioned in that the hot electrode of a belt running at the speed of the conveyor belt is surrounded, and that the additional belt is pressed onto the fiber packets is.

Das zusätzliche Band kann dabei ggf. direkt als Elektrode ausgebildet sein.The additional band can optionally be designed directly as an electrode be.

Beide Elektroden können auf Temperaturen bis über 250° elektrisch oder auf andere Weise beheizt werden, wobei die Temperatur durch Thermostate überwacht werden kann. Der Druck der 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. Die Zuführung des Faserkabels vom Krimper bis an die Elektroden des Hochfrequenzofens kann durch senkrecht stehende Kunststoffstreifen mit einer Niederhaltung, bestehend aus einem durch das Eigengewicht wirkenden Kunststoff- oder Blechstreifen vorgenommen werden.Both electrodes can be heated electrically or in some other way to temperatures up to over 250 °, whereby the temperature increases Thermostats can be monitored. The pressure of the upper electrode or the upper additional band can advantageously be set in such a way that that it can rise or fall in the running direction. Likewise, the electrodes can advantageously also be designed in this way be that the pressure value can be influenced transversely to the conveying direction. The feeding of the fiber cable from the crimper to the Electrodes of the high-frequency furnace can be supported by vertical plastic strips with a hold-down consisting of a Plastic or sheet metal strips acting under their own weight be made.

Anhand einer Zeichnung sei die Erfindung näher erläutert: Die vom nichtgezeigten Krimper auf einem Förderband 8 antransportierten Faserpakete 7 gelangen auf ein in Richtung des Pfeiles 10 laufendes geerdetes Förderband 3, welches über geerdete Rollen 6 läuft und selber als Elektrode wirkt. Überhalb „«. der Faserpakete 7 ist im Hochfrequenztrocknungsofen 1 eine an Hochspannung liegende heiße Elektrode 4 vorgesehen, welche über einen Regelkondensator 9 an die Hochspannung des Hochfrequenz-The invention will be explained in more detail with the aid of a drawing: those transported from the Krimper (not shown) on a conveyor belt 8 Fiber packets 7 arrive at a grounded conveyor belt 3 running in the direction of arrow 10, which is connected to grounded Rolls 6 runs and acts as an electrode itself. Above "". of the fiber packages 7, a high-voltage hot electrode 4 is provided in the high-frequency drying oven 1, which overlying a regulating capacitor 9 to the high voltage of the high frequency

Dieses obere Band wirkt in Verbindung mit der Elektrode 4 gleichzeitig als Niederhaltung. für die Paserpakete 7 und als Durchlaufpresse mit einstellbarem Druck. Durch das sich zwischen den Elektroden 3 und 4 ausbildende elektrische PeId und den dadurch entstehenden Dampf wird in den zusammengedrückten Paserkabeln in sehr kurzer Zeit (einige see) eine gleichmäßige Erwärmung erreicht. Auf diese Weise lassen sich verschiedene Textilwerte der behandelten Pasern verbessern, z.B. wird eine höhere Kräuselbeständigkeit erreicht.generator 2 is connected * The top electrode 4 is from surrounded by a band 11 also running in the direction of arrow 10, which runs over rollers 5. This upper band acts in conjunction with the electrode 4 at the same time as a hold-down. for the Paser packs 7 and as a throughfeed press with adjustable Pressure. Due to the electrical pressure generated between the electrodes 3 and 4 and the resulting vapor, the compressed pas cables achieved uniform heating in a very short time (a few seconds). Leave that way various textile values of the treated fibers improve, e.g. a higher resistance to curling is achieved.
