KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die gufseisernen Trockencylinder bei Papiermaschinen, die bis drei Meter Durchmesser haben und von ein bis zwei Atmosphären Druck geheizt werden, bieten namentlich hinsichtlich der auf beiden Seiten eingesetzten und die Lagerzapfen tragenden, gleichfalls aus Gufseisen bestehenden Böden eine beträchtliche Explosionsgefahr dar. Aufserdem bedürfen sie unnöthig viel Dampf.The cast iron drying cylinders on paper machines that are up to three meters in diameter have and are heated by one to two atmospheres pressure, offer in particular with regard to the one used on both sides and bearing the bearing journals, likewise Existing cast iron floors pose a considerable risk of explosion. They also require unnecessarily much steam.

Man hat diesem Uebelstand schon vergeblich durch die sogen, doppelwandigen Cylinder abhelfen wollen, welche einen inneren und äuferen Mantel aus Gufseisen hatten, die an ihren Stirnseiten durch Kränze verbunden waren und Stirnseiten mit Zapfen tragen.This problem has already been remedied in vain by the so-called double-walled cylinders want, which had an inner and outer coat of cast iron, which on their End faces were connected by wreaths and end faces with tenons.

Diese Ausführungsart hat sich aber nicht einbürgern können, weil namentlich die verschiedene Ausdehnung der beiden Mäntel Undichtigkeiten und andere Uebelstände, wie grofses Gewicht, hervorrief.However, this type of design has not been able to become naturalized because it is different Expansion of the two jackets, leaks and other inconveniences, such as great weight, caused.

Nach der vorliegenden Erfindung sollen die Trockencylinder so hergestellt werden, dafs der Aufsencylinder wie üblich aus Gufseisen abgedreht wird. Er wird an seinen beiden Stirnseiten mit einem Achskreuz versehen, welches mit einem felgenartigen Rand dicht mit einem Flantsch des Cylinders verbunden ist. Diese Felge dient auch zur Befestigung der aus Blech gebildeten Innenwand. Damit diese Innenwand leicht allen Formveränderungen des äufseren gufseisernen Mantels nachgeben kann, stellt man sie nach Fig. 1 aus Wellblech her; die Wellen läfst man rund um den Cylinder herumlaufen.According to the present invention, the drying cylinders are to be manufactured in such a way that the outer cylinder is turned from cast iron as usual. He'll look at his two Front sides provided with an axles, which with a rim-like edge tightly with is connected to a flange of the cylinder. This rim is also used to attach the Inner wall formed from sheet metal. So that this inner wall can easily accommodate all changes in the shape of the Outer cast iron jacket can give way, they are made of corrugated iron according to Figure 1; the waves are made to run around the cylinder.

Wenn man glattes Blech verwendet (Fig. 2), so setzt man Ausgleichringe G ein, ähnlich wie in Rohrleitungen, die in ihrer Wirkung den einzelnen Wellen im Cylinder D nach Fig. 1 gleichwertig sind.If smooth sheet metal is used (FIG. 2), compensating rings G are used, similar to those used in pipelines, the effect of which is equivalent to the individual waves in the cylinder D according to FIG. 1.

In die hohle Achse des Cylinders wird einerseits das Dampfrohr und andererseits das CondenswasseiTohr eingeführt und durch entsprechende radiale Anschlüsse mit dem Mantelraum verbunden.On the one hand the steam pipe and on the other hand the CondenswasseiTohr introduced and through appropriate radial connections with the shell space tied together.

Fig. 3 zeigt die Rohranordnung für das Condenswasser.Fig. 3 shows the pipe arrangement for the condensation water.

An den Flantschen a des gufseisernen Mantels A sind die Felgen b der Speichenkränze B befestigt, deren Naben c auf der hohlen Achse C sitzen. An den Felgen b sind die Stirnenden der Blechtrommel D durch passende Verschraubungen dampfdicht befestigt.The rims b of the spoke rims B , the hubs c of which sit on the hollow axis C, are attached to the flanges a of the cast iron jacket A. The front ends of the sheet metal drum D are attached to the rims b by suitable screw connections in a vapor-tight manner.

Die Ableitung des Condenswassers erfolgt durch die beiden Rohrzweige e des Rohres E, während die Dampfeinströmung durch das Rohr F erfolgt.The condensation water is discharged through the two pipe branches e of pipe E, while the inflow of steam takes place through pipe F.
