Description
Heizvorrichtung für- Hohlwalzen. Bei Dampfheizvorrichtungen für Hohlwalzen werden gewöhnlich zwei Rohre in den Hohlraum eingeführt, von denen das eine zur Zuführung des Dampfes, das andere zur Abo führung des Kondenswassers dient. Da große Mengen von Kondenswasser den Heizeffekt bedeutend vermindern, so sucht man das Kondenswasserrohr so weit nach unten abzubiegen, daß seine Mündung möglichst auf der tiefsten Stelle der Walzenhöhlung liegt. Das ist aber nicht mehr möglich, wenn der Hals der Walze sehr lang und 'der Durchrnessec ihrer Höhlung groß ist. .Heating device for hollow rolls. For steam heating devices for hollow rollers two tubes are usually inserted into the cavity, one of which leads to the Supply of the steam, the other is used to guide the condensation water. Because big If the amount of condensation water significantly reduces the heating effect, look for the condensation water pipe turn so far down that its mouth is as deep as possible the roller cavity. But this is no longer possible when the neck of the roller very long and the diameter of its cavity is large. .
Die Erfindung: ermöglicht es, auch bei Walzen mit großem Höhlungsdurchmesser und langem Hals den tiefsten Punkt der Höhfung zu entwässern, und erreicht das dadurch, daß der abgebogene Teil des Kondenswassers mit dessen achsial zur Walze liegendem Teil durch ein biegsames Mittel oder ein Gelenk verbunden ist oder daß letzterer Teil aus einem biegsamen Mittel besteht, so daß der abge bogene Teil zunächst in annähernd achsialer Lage in die Walze eingeführt und, an seine Stelle gekommen, durch mechansche Mittel oder durch sein Eigengewicht in seine tiefste Stellung gesenkt werden kann.The invention: makes it possible, even with rollers with a large cavity diameter and long neck to drain the deepest point of the elevation, and achieve this by that the bent part of the condensed water with its axially lying to the roller Part is connected by a flexible means or a hinge or that the latter Part consists of a flexible means, so that the bent part is first in introduced into the roller in an approximately axial position and, in its place, lowered to its lowest position by mechanical means or by its own weight can be.
Abli i zeigt die Heizvorrichtung in ihrer einfachsten Form im Längsschnitt. In die in bekannter Weise durch eine Stopfbüchse ahgedichtete Heizbüchse a ist das .Heizrohr b und das -Kondenswasserrohr eingesetzt, das aus einem achsial liegenden Teil c und einem schräg- nach unten gerichteten Teil d besteht, die durch ein biegsames Rohrstück, einen biegsamen Schlauch oder ein denWasserdurchfluß gestattendes Gelenk e miteinander verbunden sind. Der nach unten gerichtete Teil d kann. auch mit dem Teil e zusammen aus einem biegsamen Stück, z. B. einem-Schlauch oder einem biegsamen Rohr, bestehen'. Durch eine Verbindung f werden die beiden Rohre b und e in ihrer gegenseitigen Lage gehalten. Diese Verbindung f sowie der Anschluß des Rohres d an das Rohr e sind in ihren Abmessungen so zu halten, daß das ganzeR-ahrsystem durch den Hals der Walze hindurch aus die-. ser herausgezogen werden kann.Abli i shows the heating device in its simplest form in longitudinal section. The .Heizrohr b and the condensate water pipe is inserted into the in a known manner by a stuffing box a sealed heating sleeve, which consists of an axially lying part c and an obliquely downward part d, which consists of a flexible piece of pipe, a flexible hose or a hinge e allowing the flow of water are connected to one another. The downward part d can. also with the part e together from a flexible piece, z. B. a hose or a flexible pipe 'consist'. The two tubes b and e are held in their mutual position by a connection f. This connection f as well as the connection of the pipe d to the pipe e are to be kept in their dimensions so that the entire pipe system through the neck of the roller through. can be pulled out.
Um die Schräglage des Rohres d zu begrenzen oder zu regeln, kann es, wie in Abb. a angedeutet, mit dem Rohr b z. B. durch ein mit beiden Rohren gelenkig verbundenes Tragstück g verbunden sein, wobei das auf dem Rohr b sitzende Gelenk h auf diesem Rohr verschiebbar ist, um die Schräglage des Rohres d einstellen zu können. Die Verschiebung dieses Gelenks kann durch die Stange i von außen her erfolgen.In order to limit or regulate the inclination of the pipe d, it can as indicated in Fig. a, with the tube b z. B. articulated by one with both tubes connected support piece g be connected, the joint seated on the tube b h is slidable on this tube in order to adjust the inclination of the tube d can. This joint can be displaced from the outside by means of the rod i.
