Description
Es sind Walzen zum Bearbeiten von Kautschuk od. dgl. bekannt, die im Innern mit schraubenlinienförmig verlaufenden Leitrinnen für das Heiz-oder Kühlmittel versehen sind und dadurch eine vergrößerte Oberfläche für die Wärmeübertragung ergeben. Die bekannten Walzen dieser Art haben nach innen offene Rinnen. Hierdurch entsteht der Nachteil, daß das frische Heiz- oder Kühlmittel sich mit dem Heiz- oder Kühlmittel vermischt, das seine Wärme bzw. Kälte bereits an die Walze abgegeben hat. Dadurch tritt eine Temperaturänderung ein, die zu ihrem Ausgleich eine vergrößerte Energiezufuhr erfordert. There are rollers for processing rubber od. The like. Known that Inside with helical guide channels for the heating or cooling medium are provided and thereby result in an enlarged surface for heat transfer. The known rollers of this type have inwardly open grooves. This creates the disadvantage that the fresh heating or cooling medium with the heating or cooling medium mixed, which has already given off its heat or cold to the roller. Through this a change in temperature occurs, which is compensated for by an increased supply of energy requires.
Nach der Erfindung sind bei Walzen, in deren Mantel innen in radialer Richtung offene, schraubenlinienförmig verlaufende Leitrinnen eingearbeitet sind, in den Walzenmantel Fortsätze der Walzenzapfen eingepaßt, durch die die Leitrinnen einen geschlossenen Querschnitt erhalten. Dadurch wird die erwähnte Vermischung des frischen und des gebrauchten Heiz- oder Kühlmittels verhindert und die wirksamste Heizung bzw. Kühlung erreicht, also der Aufwand an Wärmeenergie verringert. According to the invention are in the case of rollers in the jacket inside in radial In the direction of open, helical guide channels are incorporated, in the roll shell extensions of the roll neck fitted through which the guide channels get a closed cross-section. This causes the mentioned mixing of fresh and used heating or cooling medium prevented and the most effective Heating or cooling achieved, so the amount of heat energy is reduced.
Der genannte Einsatz in die Walze erhöht deren mechanische Festigkeit, so daß der Walzenmantel dünner ausgeführt werden kann, womit ein beschleunigter Wärmeübergang verbunden ist. Die schraubenlinienförmige Leitrinne kann ohne Schwierigkeiten in den Walzenmantel eingedreht werden.The mentioned use in the roll increases its mechanical strength, so that the roll shell can be made thinner, with which an accelerated Heat transfer is connected. The helical guide channel can be used without difficulty be screwed into the roll shell.
Nach einer Ausführungsform der Erfindung sind zwei sich über je eine Hälfte der Walzenlänge erstreckende, einander parallel geschaltete Leitrinnen angeordnet. Diese besonders für längere Walzen geeignete Ausführungsform ergibt eine gleichmäßige Temperatur auf der gesamten Walzenoberfläche. According to one embodiment of the invention, two are each about one Half of the roller length extending, mutually parallel guide channels arranged. This embodiment, which is particularly suitable for longer rollers, results in a uniform one Temperature on the entire roller surface.
In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstands in Abb. 1 und 2 im Längsschnitt dargestellt. The drawing shows two exemplary embodiments of the subject matter of the invention shown in Fig. 1 and 2 in longitudinal section.
Die Walze besteht aus den Walzenzapfen a und b und dem Walzenmantel e. An den Walzenzapfen a schließt sich ein in den Mantel hineinragender zylindrischer Fortsatz c an. In diesen Fortsatz c greift der Fortsatz d des Walzenzapfens b mit Längsspiel hinein. Die Zapfenfortsätze c und d sind in den Walzenmantel e eingepaßt. Zwischen der Innenfläche des Mantels e und der Außenfläche des Fortsatzes d befindet sich eine schraubenlinienförmig verlaufende Leitrinne i für das Heiz- oder Kühlmittel, das durch die Kanäle, k2 zugeleitet und durch die Kanäle mll xn. 7 abgeleitet wird. Die schraubenlinienförmige Leitrinne i hat einen geschlossenen Querschnitt, so daß das Heiz- oder Kühlmittel zwangläufig durch sie geführt wird und sich nicht mit Kondenswasser od. dgl. vermischt. The roll consists of roll necks a and b and the roll shell e. A cylindrical protruding into the jacket closes on the roll neck a Appendix c. The extension d of the roll neck b engages in this extension c Longitudinal play into it. The pin extensions c and d are fitted into the roll shell e. Located between the inner surface of the shell e and the outer surface of the extension d a helical guide channel i for the heating or cooling medium, that fed through the channels, k2 and through the channels mll xn. 7 is derived. The helical guide channel i has a closed cross section, so that the heating or cooling medium is inevitably passed through it and not with it Condensation or the like mixed.
Bei der Ausführungsform nach Abb. 2 tragen die der Abb. 1 entsprechenden Teile der Walze die gleichen Bezugszeichen: Walzenzapfena und b, Walzenmantel e und Zapfenfortsätze c und d. Statt einer durchlaufenden Leitrinne sind hier zwei sich über je eine Hälfte der Walzenlänge erstreckende Leitrinnen i1, i2 vorgesehen, denen das Heiz- oder Kühlmittel durch die Kanäle k1, k3 und k4 gleichzeitig zugeleitet wird und die die gemeinsame Ableitung ml, m2 haben, also einander parallel geschaltet sind. Außer den Vorteilen der Walze nach Abb. I ergibt sich hier der weitere Vorteil, daß auch bei größerer Länge der Walze deren Temperatur überall gleichmäßig ist. In the embodiment according to Fig. 2 wear those of Fig. 1 corresponding Parts of the roll have the same reference numerals: roll journals a and b, roll shell e and pin processes c and d. Instead of one continuous guide channel, there are two here guide channels i1, i2 each extending over half the length of the roller are provided, to which the heating or cooling medium is fed through channels k1, k3 and k4 at the same time and which have the common derivative ml, m2, i.e. connected in parallel to each other are. In addition to the advantages of the roller according to Fig. I, there is another advantage here, that even with a greater length of the roller, its temperature is uniform everywhere.
Zwischen den beiden Walzenzapfen besteht ein Spiel, das den durch die Temperaturschwankungen bedingten Längenänderungen Rechnung trägt. There is play between the two roll journals that prevents the through takes account of changes in length caused by temperature fluctuations.
Durch die Abstützung des Walzenmantels e an den Zapfenfortsätzen c, d wird die mechanische Festigkeit der Walze erhöht, so daß der Walzenmantel e verhältnismäßig sehr dünn ausgeführt werden kann und dementsprechend ein guter Wärmeübergang erreicht wird. By supporting the roll shell e on the pin extensions c, d the mechanical strength of the roll is increased, so that the roll shell e can be made relatively very thin and accordingly a good heat transfer is achieved.
