Description
Einrichtung zum Trocknen der Filze und Stoffbahnen von Papier-, Pappen-, Zellstoff-, Karton- und ähnlichen Maschinen. Es sind bereits Einrichtungen bekannt, bei denen zur Unterstützung des Trockenvorganges in der Trockenzylinderpartie von Papier-und ähnlichen Maschinen heiße Druckluftströme an die Papier-, Pappen-, Zellstoffbahnen o. dgl. sowie auch an die Trockenfilze geführt werden.Device for drying felts and fabric webs from paper, cardboard, Pulp, cardboard and similar machines. Facilities are already known where to support the drying process in the drying cylinder section of Paper and similar machines hot compressed air flows to the paper, cardboard, pulp webs o. The like. As well as to the drying felts.
Bei diesen tekannten Einrichtungen wird die heiße Luft in außerhalb der Maschine liegenden Heizkörpern erzeugt und mittels Gebläse und Rohrleitungen an die Verwendungsstellen gedrückt.In these known facilities, the hot air is in outside radiators lying on the machine and by means of blowers and pipes pressed to the points of use.
Bei großen Trockenzylinderpartien werden diese Leitungen sehr lang, wodurch ein großer Teil der erzeugten Wärme durch Ausstrahlung verlorengeht und die Warmluft an Dampfaufnahmefähigkeit verliert. Es ist auch l:ekannt, die Stirnhöden der Trockenzylinder zur Erwärmung der Druckluft zu benutzen; hierbei sind ebenfalls große Abkühlungsflächen vorhanden.In the case of large dryer cylinder sections, these lines are very long, whereby a large part of the generated heat is lost through radiation and the warm air loses its ability to absorb steam. It is also known, the frontal horns to use the drying cylinder to heat the compressed air; here are also large cooling surfaces available.
Bei der Erfindung soll dieser Übelstand dadurch beseitigt werden, daß die Lufterhitzer an Stelle von Filztrockenzylindern in die Trockenpartie der Papier-, Pappen-, Zellstoff-, Kartonmaschinen u. dgl. derart eingebaut sind, daß die Filze so um die Erhitzer geführt «,erden, daß ihre ausstrahlende Wärme 4rocknend auf sie einwirkt; außerdem gelangt noch unmittelbare Heißluft aus dem Erhitzer durch Düsen an die Filze und durch besondere Leitungen auch an die Papierbahn, sättigt sich mit Wasserdampf und zieht seitlich ab. Auf diese Weise ist die beste Wärmeausnutzung geschaffen. Durch den Wegfall der umlaufenden Filztrockenzylinder, die in der Regel von den Filzen mitgezogen werden müssen, wird ein weiterer Vorteil und eine längere Laufdauer der Filze erreicht.In the invention, this drawback is to be eliminated by that the air heater instead of felt drying cylinders in the dryer section Paper, cardboard, pulp, cardboard machines and the like are installed in such a way that the felts passed around the heater ', grounded, so that their radiating warmth dries acts on them; in addition, direct hot air from the heater comes through Nozzles on the felts and through special lines also on the paper web, saturates with water vapor and pulls off to the side. This way is the best heat utilization created. By eliminating the circulating felt drying cylinder, which is usually having to be dragged along by the felts becomes a further advantage and a longer one Lifetime of the felts reached.
Dadurch, daß jede Gruppe von Trockenzylindern ihre eigenen Lufterhitzer hat, kann auch der Wärmegrad der Heißluft für jede Gruppe eingestellt werden.In that each group of drying cylinders has its own air heater the degree of warmth of the hot air can also be set for each group.
Die Zeichnung zeigt zwei Ausführungen der Erfindung.The drawing shows two embodiments of the invention.
In Abb. i sind a und a, zylindrische, mit Dampf geheizte Lufterhitzer, um welche die Filze b, b1 so geführt sind, daß nur die öffnungen c, c" zur Einführung der Luftzuführungsrohre d und dl frei bleiben. Die frische oder vorgewärmte Luft tritt hier in die Heizkörper ein und verläßt diese durch die Rohre f, f,. Die Düsen e, e, unterstützen die Filztrocknung.In Fig.i, a and a, cylindrical steam-heated air heaters, around which the felts b, b1 are guided so that only the openings c, c ″ for insertion the air supply pipes d and dl remain free. The fresh or preheated air enters the radiator here and leaves it through the pipes f, f ,. The nozzles e, e, support felt drying.
Bei der Ausführung nach Abb. 2 sind die Lufterhitzer flach gehalten, wodurch sich eine einfachere Filzführung ergibt.In the version according to Fig. 2, the air heaters are kept flat, which results in a simpler felt guide.
