Description

Befestigung U-förmiger Strahlungsheizrohre in Vakuumtrocknern In den deutschen Patenten Sao 130, 934 698 und 948 678 sind Befestigungen U-förmiger Strahlungsheizrohre in besonderen Bauformen von Vakuumbandtrocknern geschützt. Diese Befestigungen sind derart, daß die freien Schenkel der U-förmigen Strahlungsheizrohre durch öffnungen bzw. Schlitze in der Trocknerwand mit Abstand von derselben geführt sind und daß über die Öffnungen an ihrem äußeren Ende geschlossene Überwurfrohre bzw. über die Schlitze Kästen gestülpt sind, die fest mit der Trocknerwand verbunden sind, und daß die freien Schenkel der U-Rohre mit Abstand von der Rohrwand bzw. den Kastenwänden in den Rohren bzw. Kästen bis zu deren äußerem Ende, in dem sie gelagert sind, geführt sind und dort nach außen durchtreten. Es werden dadurch Wärmespannungen vermieden.Fastening U-shaped radiant heating pipes in vacuum dryers In the German patents Sao 130, 934 698 and 948 678 are fastenings for U-shaped radiant heating tubes Protected in special designs by vacuum belt dryers. These fortifications are such that the free legs of the U-shaped radiant heating tubes through openings or slots in the dryer wall are guided at a distance from the same and that over the openings at their outer end closed cap tubes or over the Slots are put upside down, which are firmly connected to the dryer wall, and that the free legs of the U-tubes at a distance from the tube wall or the box walls out in the tubes or boxes to the outer end in which they are stored and step through there to the outside. This avoids thermal stresses.

Es hat sich gezeigt, daß diese Art der Strahlungsheizrohrbefestigung für alle Bauarten von Vakuumtrocknern vorteilhaft anwendbar ist.It has been shown that this type of radiant heating tube fastening can be used advantageously for all types of vacuum dryer.
