Description
Vorrichtung zum Trocknen pulverförmiger bis körniger Güter durch Reibungswärme Die Erfindung bezieht sich auf eine Vorrichtung zum Trocknen pulverförmigen bis körnigen Gutes, in der das Gut durch Reibungswärme erwärmt wird. In bekannten Vorrichtungen für diesen Zweck wird die Reibungswärme z. B. durch zwei in einem Rohr sich gegenläufig drehende Schnecken erzeugt oder es wird ein auf der Spitze stehender, sich rasch drehender Kegel verwendet, der sich, einen treppenförmigen Ringspalt für das Gut freilassend, in einem Hohlkegel dreht. In diesen Geräten wird das Gut durchReibungswärme getrocknet und gleichzeitig zwangläufig gefördert. Die Intensität des Trocknungsvorganges und dessen Dauer kann dabei nicht unabhängig von der Gutförderung gesteuert werden.Device for drying powdery to granular goods using frictional heat The invention relates to an apparatus for drying powdery to granular goods in which the goods are heated by frictional heat. In known devices for this purpose the frictional heat z. B. by two in a tube in opposite directions rotating snails or it becomes an upside-down one that moves rapidly rotating cone used, a step-shaped annular gap for the good leaving free, turns in a hollow cone. In these devices, the product is heated by frictional heat dried and at the same time inevitably promoted. The intensity of the drying process and its duration cannot be controlled independently of the material conveyance.
Der Erfindung liegt die Aufgabe zugrunde, die Intensität des Trocknungsvorganges bei dem durch Reibungswärme die notwendige Energie entsteht und dessen Dauer unabhängig von der Gutförderung zu steuern.The invention is based on the object of increasing the intensity of the drying process in which the necessary energy is generated by frictional heat and its duration is independent to control of the good conveyance.
Die Erfindung besteht darin, daß bei der eingangs beschriebenen Vorrichtung als Trockner ein zylindrischer Behälter mit lotrechter Achse und einem um diese Achse umlaufenden Rührer im Bodenbereich verwendet wird, der mit so hoher Drehzahl umläuft, daß die dabei erzeugte Reibungswärme zum Trocknen des Gutes ausreicht.The invention consists in that in the device described above as a dryer, a cylindrical container with a vertical axis and one around it Axis rotating stirrer in the bottom area is used, which is at such a high speed runs around so that the frictional heat generated is sufficient to dry the goods.
Es kann dabei vorteilhaft sein, auf dem Behälterboden einen Stiftkranz und am Rührer einen Gegenstiftkranz anzuordnen. Der Rührer kann auch bis an die Behälterwand reichende Schlagarme haben.It can be advantageous to have a ring of pins on the bottom of the container and to arrange a counter pin ring on the stirrer. The stirrer can also reach the Have striking arms that reach the container wall.
Es wurde festgestellt, daß bei einer erfindungsgemäßen Vorrichtung mit einem Kranz stehender Stifte auf dem Boden des Behälters und einem umlaufenden, lange Schlagarme tragenden Gegenstiftkranz schon bei einem Stiftkranzdurchmesser von 25 cm und einer Stiftlänge von etwa 50 mm ungefähr 10 kW im Trocknungsgut abgesetzt werden können. Die an das Gut abzugebende Energie läßt sich durch Verändern der Guthöhe im Behälter, des Durchmessers des laufenden Stiftkranzes oder der Rührerdrehzahl beliebig einstellen. Die Energieabgabe an das Gut kann auch durch Verändern der Relativgeschwindigkeit der Stiftkränze eingestellt werden, wobei dann der am Boden liegende Stiftkranz in entgegengesetzter Richtung umläuft.It was found that in a device according to the invention with a wreath of standing pens on the bottom of the container and a surrounding, long flapping arms carrying counter pin ring with a pin ring diameter of 25 cm and a pin length of about 50 mm approximately 10 kW deposited in the material to be dried can be. The energy to be given to the good can be changed by changing the Good height in the container, the diameter of the running pin ring or the stirrer speed set as desired. The energy transfer to the good can also be achieved by changing the Relative speed of the pin rings can be set, then the one on the ground lying pin ring revolves in the opposite direction.
Die Zeichnung zeigt schematisch ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung.The drawing shows schematically an embodiment of the invention Contraption.
Fig.1 einen lotrechten Schnitt, Fig.2 einen waagerechten Schnitt.Figure 1 is a vertical section, Figure 2 is a horizontal section.
Im Trocknungsbehälter 1 rotiert der von dem Motor 2 angetriebene Rührer 3. Am Behälterdeckel 4 ist der Entlüftungsstutzen 5 und der Aufgabetrichter 6 angebracht. Das in den Behälter 1 eingefüllte Gut erhält die zum Trocknen erforderliche Wärme als Reibungswärme, die im Gut durch die Rotation des Rührers 3 mit dem Stiftkranz 7 und den Schlagarmen 8 und 9 entsteht. Die Schlagarme 8 und 9 reichen bis fast an die Behälterwand 10 und können beliebige Querschnittsformen aufweisen und gerade oder innen oder außen abgebogen sein. Der Gegenstiftkranz 11 kann am Boden befestigt sein oder auch umlaufen. Es können auch an Stelle der beiden Stiftkränze 7 und 11 mehrere Stiftkränze und es können auch mehr als zwei Schlagarme angeordnet sein. Das getrocknete Gut wird dem Behälter 1 durch die Bodenöffnung 12 entnommen. Das Bezugszeichen 13 deutet die Gutbewegung in lotrechter Ebene an.In the drying container 1 , the stirrer 3 driven by the motor 2 rotates. The venting nozzle 5 and the feed hopper 6 are attached to the container cover 4. The material filled into the container 1 receives the heat required for drying as frictional heat, which is generated in the material by the rotation of the stirrer 3 with the pin ring 7 and the beater arms 8 and 9. The striking arms 8 and 9 extend almost to the container wall 10 and can have any cross-sectional shape and be straight or bent inside or outside. The counter pin ring 11 can be attached to the floor or also rotate. Instead of the two pin rings 7 and 11, several pin rings and more than two striking arms can also be arranged. The dried material is removed from the container 1 through the bottom opening 12. The reference number 13 indicates the movement of the material in a vertical plane.
