  Anordnung an direkt geheizten Zellstoffkoehern mit inwendigem Umlauf. 



   Die Erfindung betrifft Zellstoffkocher, bei denen der Heizdampf einer innerhalb des Kochers angeordneten Vorrichtung zugeführt wird. der einen Teil einer inwendigen Umlaufleitung bildet. 



   Die Erfindung bezweckt. eine einfache und zweckentsprechende Befestigung für diese Vorrichtung und für die Leitung, mittels welcher Dampf zu der Vorriehtung geführt wird, zu schaffen. 



   Die Lösung dieser Aufgabe hat wegen der grossen Zerbrechlichkeit und des   hohen Wärmeaus-   dehnungskoeffizienten der Materialien, säurefester Stahl, die für   einige Teile der Anordnung verwendet   werden müssen, verschiedene praktische Schwierigkeiten geboten. 



   Gemäss der Erfindung wird eine einfache und sichere   Befestigung geschaffen, welche   freie Be eg-

   PATENT-ANSPRÜCHE :   1. Anordnung an Zellstoftkochern, bei#denen der Heizdampf einer   im Innern des Kochers angeordneten   Vorrichtung zugeführt wird.   die einen Teil einer   inwendigen Umlaufleitungfür   die Lauge bildet. dadurch gekennzeichnet. dass die Vorrichtung   (6)   mit der Kocherwandung (16) mittels eines Rohr-

  Arrangement on directly heated pulp boxes with internal circulation.



   The invention relates to cellulose digesters in which the heating steam is fed to a device arranged inside the digester. which forms part of an internal circulation line.



   The invention aims. to create a simple and appropriate attachment for this device and for the line by means of which steam is fed to the Vorriehtung.



   The solution to this problem has presented various practical difficulties because of the great fragility and the high coefficient of thermal expansion of the materials, acid-proof steel, which must be used for some parts of the arrangement.



   According to the invention, a simple and secure attachment is created, which free Be eg-

 of the outer T-shaped pipe is attached to the crosspiece 6 of the T-pipe by means of a pipe socket 11.



   On the outside, the shaft 7 has a flange 12, which in the Kocherv andung mediated by a

   PATENT CLAIMS: 1. Arrangement on pulp digesters in which the heating steam is fed to a device arranged inside the digester. which forms part of an internal circulation line for the liquor. characterized. that the device (6) with the digester wall (16) by means of a pipe
 EMI2.2
 goes through the pipe socket.

 

Claims (1)

2. Anordnung nach Anspruch 1. dadurch gekennzeichnet. dass der Dampfverteiler (9), welcher koaxial mit dem betreffenden Teil (6) der Laugenumlaufleitung verbunden ist, ungefähr auf der Mitte auf dem inneren Ende des Dampfzufuhrrohres (8) festgeklemmt ist, das gleichzeitig die Tragvorrichtung der Dampf Verteilung bildet, mittels einer Klemmschraube (22), welche durch einen abnehmbaren Deckel (23) auf dem rohrförmigen Behälter (6) vom Inneren des Kochers zugänglich ist. EMI2.3 2. Arrangement according to claim 1, characterized. that the steam distributor (9), which is coaxially connected to the relevant part (6) of the liquor circulation line, is clamped approximately in the middle on the inner end of the steam supply pipe (8), which at the same time forms the support device for the steam distribution, by means of a clamping screw ( 22), which is accessible from inside the cooker through a removable cover (23) on the tubular container (6).
