1. Vorrichtung zur Unterdruck-Läuterung einer Glasschmelze mit einem por­ talartigen Unterdruck-Apparat, in dem die Glasschmelze über ein verti­ kales Steigrohr einer horizontalen Läuterbank zugeführt und über ein vertikales Fallrohr aus der Läuterbank wieder abgeführt wird, wobei über dem Glasfluss in der Läuterbank ein Unterdruck erzeugt wird und Vor­ kehrungen zur Zurückhaltung des über dem Glasfluss in der Läuterbank entstehenden Schaumteppichs vom Eintritt in das Fallrohr getroffen sind, dadurch gekennzeichnet,
dass ein Übergangsbereich (15e) des Steigrohres (15a) in die Läuterbank (15b) sich im Querschnitt ausgehend vom Querschnitt des Steigrohres (15a) vergrößert, und/oder
dass ein Übergangsbereich (15d) des Fallrohres (15c) in die Läuterbank (15b) sich im Querschnitt ausgehend vom Querschnitt des Fallrohres (15c) vergrößert.1. Device for vacuum refining of a glass melt with a por tal-like vacuum apparatus in which the glass melt is fed to a horizontal refining bench via a vertical riser pipe and is discharged again from the refining bench via a vertical downpipe, with an above the glass flow in the refining bench Vacuum is generated and precautions are taken to retain the foam carpet that forms over the glass flow in the refining bank from entering the downpipe, characterized in that
that a transition region ( 15 e) of the riser pipe ( 15 a) into the refining bench ( 15 b) increases in cross section from the cross section of the riser pipe ( 15 a), and / or
that a transition area ( 15 d) of the downpipe ( 15 c) into the refining bench ( 15 b) increases in cross section from the cross section of the down pipe ( 15 c). 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass sich der Querschnitt im Übergangsbereich (15e) des Steigrohres (15a) zur Läuterbank (15b) kontinuierlich, vorzugsweise trichterförmig vergrößert. 2. Device according to claim 1, characterized in that the cross section in the transition region ( 15 e) of the riser pipe ( 15 a) to the refining bench ( 15 b) increases continuously, preferably in a funnel shape. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass sich der Querschnitt im Übergangsbereich (15d) des Fallrohres (15c) in die Läuterbank (15b) kontinuierlich, vorzugsweise trichterförmig ver­ größert.3. Device according to claim 1 or 2, characterized in that the cross section in the transition region ( 15 d) of the downpipe ( 15 c) in the refining bank ( 15 b) increases continuously, preferably funnel-shaped ver. 4. Vorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass in der Läuterbank (15b) zumindest eine Schaumbarriere (19) ange­ ordnet ist.4. Device according to one of claims 1 to 3, characterized in that in the refining bank ( 15 b) at least one foam barrier ( 19 ) is arranged. 5. Vorrichtung nach Anspruch 4, dadurch gekennzeichnet,
dass die Schaumbarriere (19) im Wesentlichen horizontal ausgerichtet ist und zumindest den Eingang des Übergangsbereichs (15d) zum Fallrohr (15c) überdeckt, und
dass die Schaumbarriere (19) stets unter der Oberfläche des Glasflusses (17b) in der Läuterbank (15b) angeordnet ist.5. The device according to claim 4, characterized in
that the foam barrier ( 19 ) is oriented essentially horizontally and at least covers the entrance of the transition region ( 15 d) to the downpipe ( 15 c), and
that the foam barrier ( 19 ) is always arranged below the surface of the glass flow ( 17 b) in the refining bench ( 15 b).
