Description

Im Hauptpatent 532 894 ist ein VerfahrenIn the main patent 532 894 there is a method

zum Trocknen von Kunstseidespinnkuchen und kuchenähnlichen Fadenwickeln beschrieben, bei dem die Kuchen durch längs der Außen- und Innenseite getrocknete Luftströme so weit vorgetrocknet werden, daß die Fadenlagen für Luft durchlässig werden, worauf bis zur völligen Trocknung ein Luftstrom durch die Fadenlagen des Kuchens hindurchgeleitetfor drying artificial silk cakes and cake-like thread wraps described, in which the cakes so far by air currents dried along the outside and inside are pre-dried that the thread layers are permeable to air, whereupon up to a stream of air passed through the thread layers of the cake to complete drying

to wird.to will.

Gegenstand vorliegender Erfindung ist ein Kanaltrockenofen, der so eingerichtet ist, daß er die Trocknung der Spinnkuchen oder ähnlicher Fadenwickel nach dem im Hauptpatent beschriebenen Verfahren gestattet. Dadurch ist es möglich, die an sich bekannten Vorteile der Kanaltrockner auch für Spinnkuchen nutzbar zu machen. Die in Kanaltrocknern bisher vorgesehenen Hilfsmittel zum Trocknen textiler Wickelkörper waren aus, "den im Hauptpatent dargelegten Gründen nicht geeignet, auch Spinnkuchen einwandfrei in entsprechender Zeit und mit geringem Dampfverbrauch zu trocknen.The present invention is a tunnel drying oven which is set up so that he drying the spinning cake or similar thread lap according to the main patent procedure described. This makes it possible to have the advantages known per se to make the tunnel dryer usable for spinning cakes as well. The drying aids previously provided in tunnel dryers textile bobbins were not suitable for "the reasons set out in the main patent, also spinning cake flawlessly in the appropriate time and with low steam consumption to dry.

Der die Erfindung bildende Kanaltrockner ist in der Zeichnung in Abb. 1 im Längsschnitt, in Abb. 2 im Querschnitt sowie in Abb. 3 und 4 in besonderen Einzelheiten dargestellt.The tunnel dryer forming the invention is shown in the drawing in Fig. 1 in longitudinal section, shown in Fig. 2 in cross section and in Fig. 3 and 4 in particular details.

Die nassen Spinnkuchen α werden einzeln auf Träger b gebracht, die ineinandergesteckt und zu Säulen angeordnet werden. Diese Kuchensäulen werden auf Gestellen c so angebracht, daß sich auf der Tragplatte^ unter jeder Kuchensäule eine Öffnung^ befindet, die zur Zuführung der vorgewärmten Luft dient. Die Kuchensäulen werden oben durch Deckel/ gehalten und verschlossen, die durch Federn g" niedergedrückt werden. Die so ausgerüsteten Gestelle mit den nassen Kuchen werden in den Trockenofen eingeführt, der als Kanalofen ausgebildet ist. Sie werden hierauf von einem Förderband oder einer Förderkette h erfaßt und mit ge- *5 eigneter Gesehwin'digkeit durch die einzelnen Zonen des Ofens, wie Vortrocknungszone, eigentliche Trockenzone, Kühl- und evtl. Befeuchtungsizone hindurchgeführt. Die Luft wird hierbei z. B. durch die Heizkörper i vorgewärmt und hierauf von unten durch die Öffnungen e der Bodenplatten? den Kuchen zugeführt. Dabei ist Sorge zu tragen, daß die Platte d seitlich so -weit abdichtet, daß die Hauptmenge 'der Luft gezwungen ist, ihren Weg durch die Öffnungen e zu nehmen. Eine kleinere Menge Luft strömt neben der Bodenplatte und dann seitlich an den Kuchen vorbei. Diese Luft 'dient zur oberflächlichen Vortrocknung. Falls die seitlich an den Bodenplatten vorbedstreichende Luft hierzu nicht ausreicht, können die Bodenplatten auch noch mit kleinen Öffnungen versehen werden, die zwischen den Löchern e angeordnet sind, ebenso ist es zweckmäßig, die Deckel/ mit kleinen Öffnungen zu versehen, um die Kuchen auch innen vorzutrocknen, bis die Hauptmenge der Luft durch die Fadenlagen des vorgetrockneten Kuchens selbst strömen kann.The wet spinning cakes α are placed individually on carriers b , which are inserted into one another and arranged in columns. These cake columns are mounted on racks c in such a way that there is an opening on the support plate under each cake column, which is used to supply the preheated air. The cake columns are held and closed at the top by covers / which are pressed down by springs g ". The racks with the wet cakes thus equipped are introduced into the drying oven, which is designed as a channel oven. They are then picked up by a conveyor belt or a conveyor chain h and 5 suitably Gesehwin'digkeit passed with overall * through the individual zones of the oven, such as predrying zone, actual drying zone, cooling and possibly Befeuchtungsizone. the air is here z. B. i preheated by the heater and then from below by Openings e of the bottom plates - the cake. Care must be taken that the plate d is sealed at the sides so that the majority of the air is forced to make its way through the openings e . A smaller amount of air flows next to the Floor plate and then past the side of the cake. This air is used for surface pre-drying This is not sufficient, the bottom plates can also be provided with small openings, which are arranged between the holes e , it is also useful to provide the lid / with small openings to pre-dry the cake inside until the main amount of air through the thread layers of the pre-dried cake itself can flow.

Die zum Trocknen benutzte Luft wird hierauf durch in der Decke des Trockenkanals angebrachte Öffnungen oder Schlitzet mittels der Ventilatoren oder Schleudergebläse/ abgesaugt und neuerdings den Heizkörpern/ zugeführt. Die Luftführung im einzelnen erfolgt in beliebiger Weise. Besonders geeignet ist für den vorliegenden Zweck ein Verfahren, wie es in der deutschen Patentschrift 354 933 gezeigt wird.The air used for drying is then passed through the ceiling of the drying tunnel openings or slots made by means of fans or centrifugal blowers / sucked off and recently fed to the radiators /. The air flow takes place in detail in any way. A method is particularly suitable for the present purpose, as shown in German Patent 354,933.

Die einzelnen Gestelle tragen unten Blechern, die die aufeinanderfolgenden Abschnitte des Trockners in der Längsrichtung gegeneinander abgrenzen, um ein Übertreten der Luft unterhalb der Platten von einem Abschnitt in den anderen zu verhindern. ·The individual racks carry sheet metal below, which form the successive sections of the dryer in the longitudinal direction to prevent the air from escaping below the plates from one section to prevent in the other. ·
