Description

Vorrichtung zum Trocknen von Papier-, Pappen-, Papierstoff- und Gewebebahnen mit Hilfe von Trockenzylindern, die der Reihe nach vom Heizmittel durchströmt werden. Bei der Vorrichtung nach dem Patent 3 185o2 kann es in manchen Fällen vorteilhaft sein, die der zu trocknenden Papier- oder Stoffbahn entsteigenden Dämpfe nicht vom Heizmittelstrom einsaugen zu lassen, um VVasserabscheidungen im Innern der Trockenzvlinder zu vermeiden. Der Übelstand kann sich besonders bei den ersten Trockenzylindern zeigen, wo die Stoffbahn noch feucht und nicht so warm ist und die Temperatur des Heizmittels schon abgenommen hat.Device for drying paper, cardboard, paper pulp and fabric webs with the help of drying cylinders through which the heating medium flows in sequence. In the case of the device according to patent 3,185o2 it can be advantageous in some cases the vapors emerging from the paper or fabric web to be dried are not released from the Allow the heating medium flow to be sucked in to prevent water separations inside the drying cylinder to avoid. The problem can be felt especially with the first dryer cylinders show where the length of fabric is still damp and not so warm and the temperature of the Heating medium has already decreased.

Dem Übelstand soll nach der Erfindung in der Weise abgeholfen werden, daß die Durchbrechungen der Trockenzylindermäntel in eine besondere Leitung münden, die mit einem besonderen Absauger in Verbindung steht, so daß die gesamten Abdämpfe oder wenigstens der größteTeil davon nicht durch dieTrocken-' zylinder selbst, sondern durch besondere, in die letzteren eingebaute, nach außen führende Rohre abgeführt werden.According to the invention, the problem is to be remedied in such a way that that the openings in the drying cylinder jacket open into a special line, which is connected to a special suction device, so that all the fumes or at least most of it not through the drying cylinders themselves, but rather Discharged through special pipes built into the latter, leading to the outside will.

Die Zeichnung stellt die neue Vorrichtung in Fig. i in der Längsansicht und im teilweisen Schnitt, in Fig. 2 im Zusammenhang mit einer Trockenzylindergruppe dar.The drawing represents the new device in Fig. I in the longitudinal view and in partial section, in FIG. 2 in connection with a drying cylinder group represent.

Die Trockenzylindermäntel a (Fig. i) haben hier z. B. beiderseits je einen Kranz von Durchbrechungen 31, die innen im Mantel a in an ihn anliegende hohle Kränze 34 münden, deren Hohlräume sich in hohle Arme 33 und hohle Zäpfen 32 fortsetzen. An die sich drehenden Zapfen 32 wird beiderseits je ein feststehendes Luftsaugrohr35 angedrückt, das mit einem Absauger zum Absaugen der Abdämpfe in Verbindung steht. Der Mantel a ist mit den Kränzen 34, Armen 33 und Zapfen 32 fest verbunden und bildet mit ihnen den Trockenzylinder, der beiderseits offen ist, mit den offenen Enden je in Heizmittelleitungen e eingreift und innen von einem Heizmittelstrom in Achsenrichtung durchstrichen wird; die Abdämpfe werden durch die Durchbrechungen 31 rings um den ganzen Mantel a eingesaugt.The drying cylinder jackets a (Fig. I) have here z. B. both sides a wreath of perforations 31 each, the inside of the jacket a in abutting against him hollow rims 34 open, the cavities of which extend into hollow arms 33 and hollow cones 32 continue. A stationary pin is attached to each of the rotating pins 32 on both sides Luftsaugrohr35 pressed on, which is connected to a suction device for sucking off the fumes stands. The jacket a is firmly connected to the rings 34, arms 33 and pins 32 and with them forms the drying cylinder, which is open on both sides, with the open ones Each end engages in heating medium lines e and inside of a heating medium flow is crossed in the axial direction; the fumes are through the openings 31 sucked in all around the mantle a.

In vielen Fällen wird es aber genügend sein, wenn die Abdämpfe nur so weit am Umfange der Trockenzylindermäntel a eingesaugt werden, als die Papier- oder Stoffbahn auf dem Zylinder läuft, also etwa von Stelle 37 bis Stelle 38 (Fig. 2). Für diesen Sonderfall gehen die Saugkränze 39 auch nur von Stelle 37 bis 38 und sind nicht mit dem Zylindermantel a verbunden, sondern stehen fest, während die Mäntel a auf beiderseits auf Achsen befestigten, angetriebenen Rollen 36 oder durchgehenden Walzen 361 laufen und weder Armkreuze noch Zapfen besitzen. Die Saugkränze 39 besitzen hohle Arme 4o und durch die Mitte sich erstreckende Rohre .1.i, die mit dem Absauger in fester Verbindung stehen. Die Vorrichtung nach F ig. 2 kann um das Zylindermittel verstellt werden.In many cases, however, it will be sufficient if the fumes only as far as the circumference of the drying cylinder jacket a is drawn in as the paper or the web of material runs on the cylinder, i.e. from about 37 to 38 (Fig. 2). For this special case, the suction cups 39 only go from position 37 to 38 and are not connected to the cylinder jacket a, but are fixed while the jackets a on both sides mounted on axles, driven rollers 36 or continuous rollers 361 run and have neither spiders nor pegs. The suction cups 39 have hollow arms 4o and extending through the middle Pipes .1.i that are permanently connected to the extractor. The device according to Fig. 2 can be adjusted around the cylinder center.

Während man beim Einsaugen der Dämpfe mittels des Heizmittelstromes an dessen Geschwindigkeit und Luftverdünnung gebunden ist, kann man mit der neuen Vorrichtung mit beliebiger Luftverdünnung arbeiten. Da man mit der Vorrichtung auch die Papier- oder Stoffbahn, besonders zu ihrem Aufführen, ansaugen kann, wird man dazu beim Inbetriebsetzen der Papiermaschine zunächst eine geringe Luftverdünnung wirken und dann nach dem Aufführen der Bahn eine stärkere Luftverdünnung behufs Absaugens der Dämpfe einsetzen lassen.While sucking in the vapors by means of the heating medium flow the speed and dilution of the air can be used with the new Work device with any air dilution. Since you are with the device too can suck the paper or fabric web, especially for its execution, one becomes in addition, when starting up the paper machine, initially a small amount of air dilution act and then, after the web has been drawn up, a stronger air dilution for the purpose Allow the vapors to be extracted.

Die neue Vorrichtung läßt sich auch bei den bekannten, mit Dampf geheizten Trockenzylindern anwenden.The new device can also be used with the known, steam-heated Use drying cylinders.
