Description

Röhrentrockner Bei den bekannten Schulzschen Röhrentrocknern mit in den Trockenrohren eingebauten Heizrohren treten an den Verbindungsstellen der Heizrohre mit dem Trockenrohr infolge ungleicher Ausdehnung der Rohre Brüche ein. Gemäß der Erfindung wird dieser Mangel dadurch beseitigt, daß die eingebauten Heizrohre -als Ausdehnungsrohre ausgebildet sind.Tube dryer With the well-known Schulz tube dryers with in The heating pipes built into the drying pipes occur at the connection points of the heating pipes breaks with the drying tube as a result of the uneven expansion of the tubes. According to the Invention, this deficiency is eliminated in that the built-in heating pipes -as Expansion pipes are formed.

Der Erfindungsgegenstand wird in der Zeichnung in verschiedenen Ausführungsbeispielen dargestellt, und zwar stellt dar Abb. r einen Röhrentrockner mit Trockenrohren, in die die Heizrohre als Ausdehnungsrohre eingebaut sind.The subject of the invention is shown in the drawing in various exemplary embodiments shown, namely Fig.r shows a tube dryer with drying tubes, in which the heating pipes are installed as expansion pipes.

Abb.2 zeigt ein solches Rohr mit einem schraubenförmig gewundenen, linksgängigen Ausdehnungsrohr im Längsschnitt, Abb. 3 ein solches mit einem rechtsgängigen Ausdehnungsrohr, Abb. q. ein Trockenrohr mit einem zum Teil links und rechts gewundenen Heizrohr, wobei auch die Steigungen der einzelnen Windungen verschieden sind.Fig.2 shows such a pipe with a helically wound, left-hand expansion pipe in longitudinal section, Fig. 3 one with a right-hand one Expansion pipe, Fig.q. a drying tube with a partly twisted left and right Heating pipe, with the gradients of the individual windings also being different.

Abb. 5 zeigt ein Heizrohr in Bogen- bzw. Lyraform und Abb. 6 ein als Wehrohr ausgebildetes Heizrohr.Fig. 5 shows a heating tube in arch or lyre shape and Fig. 6 as Deflector tube formed heating tube.

In die einzelnen Trockenrohre eines Röhrentrockners werden Heizrohre als Ausdehnungsrohre beliebiger Art, beispielsweise schraubenförmige (Abb. 2 bis q.), lyra- bzw. bogenförmige (Abb. 5) oder wellrohrförmige (Abb. 6), eingebaut, um die beim Erwärmen oder Erkalten des Trockners auftretenden Spannungen, die durch ungleiche Ausdehnungen oder Verkürzungen im Trocken- und Heizrohr entstehen, auszugleichen. Dabei können die Trockenrohre und die als Ausdehnungsrohre ausgebildeten Heizrohre beliebig geformte Querschnitte besitzen. Auch können die Heizrohre nur an einer oder an mehreren Stellen mit dem Trockenrohr fest verbunden sein. Durch die Verbindung mit dem Trockenrohr wird auch gleichzeitig der erforderliche Heizdampf o. dgl. dem Heizrohr zugeführt. Es können in einem Trockenrohr ein oder mehrere Ausdehnungsrohre auf die ganze Länge oder nur auf einen Teil der Länge des Trockenrohres eingebaut werden. Das zu trocknende Gut (Kohle o. dgl.) wird den Trockenrohren des Trockners an der hochliegenden Stirnwand aufgegeben und gelangt durch die Drehung des Trockners und dadurch der Trockenrohre nach der tiefliegenden Stirnwand und fällt dort getrocknet aus.Heating tubes are inserted into the individual drying tubes of a tube dryer as expansion pipes of any type, for example helical (Fig. 2 to q.), lyra-shaped or arched (Fig. 5) or corrugated tubular (Fig. 6), built-in, about the stresses that occur when the dryer is heated or cooled down, which is caused by unequal expansions or shortenings in the drying and heating pipes arise, to compensate. The drying tubes and the heating tubes, which are designed as expansion tubes have any shape cross-sections. The heating pipes can also only be connected to one or be firmly connected to the drying tube at several points. Through the connection With the drying tube, the required heating steam or the like is also at the same time Heating pipe fed. There can be one or more expansion tubes in a drying tube Installed over the entire length or only part of the length of the drying tube will. The material to be dried (coal or the like) is the drying tubes of the dryer abandoned on the high front wall and gets through the rotation of the dryer and thereby the drying tube to the deep end wall and falls there dried the end.

Haben die als Ausdehnungsrohre eingebauten Trockenrohre eine gerade oder Wellenform, so wird das Trockengut durch die Heizrohre gleichzeitig gewendet. Soll das Trockengut im Trockner eine längere Zeit verweilen, als es der Schräglage des Trockners entspricht, so müssen schraubenförmige Heizrohre eingebaut werden, die eine entgegengesetzte Windung gegenüber der Drehrichtung des Trockners besitzen. Man wird beispielsweise das schraubenförmige Ausdehnungsrohr so ausbilden, daß an der Trockenguteintrittsstelle das zu trocknende Gut nach innen gezogen wird, während es auf dem längeren Trockenweg durch entgegengesetzteWindungen zurückgehalten wird. Auch kann man die einzelnen Windungen in ihren Steigungen verschieden halten, um so die Trockendauer des Gutes zu regeln.Do the drying pipes installed as expansion pipes have a straight line or wave shape, the drying material is turned at the same time by the heating pipes. Should the items to be dried remain in the dryer for a longer time than the inclined position of the dryer, then helical heating pipes must be installed, which have an opposite turn to the direction of rotation of the dryer. For example, the helical expansion pipe will be designed so that on the dry goods entry point, the goods to be dried are pulled inwards, while it is held back on the longer dry path by opposing windings. You can also keep the individual turns different in their gradients in order to in this way to regulate the drying time of the goods.
