Description
Antriebsanordnung für Wendelrutschen von Vertikaltrocknern Die Erfindung betrifft eine Antriebsanordnung für Wendelnutschen von Vertikaitrocknern. Derartige Wendelrutschen werden benutzt, um das auf den Rutschflächen feinverteilte Gut in innige Berührung mit den trocknenden Medien, wie Luft oder Gasen, ZU bringen. Zu diesem Zweck werden die zu trocknenden Medien auf den Arbeitsflächen der Wendelrutschen verteilt, und die wirksamen Arbeitsflächen erhalben eine hin- und hergehende oder eine in einer Richtung verlaufende Drehbewegung. Bei den bekannten Wendelrutschen wird dabei gleichzeitig eine Neigung der Wendelrutsehbahnen vorgesehen, die so gehalten ist, daß der Neigungswinkel der Bahnen kleiner ist als der Reibungswinkel des Gutes an der Oberfläche. Das Gut rutscht also nicht von selbst nach unten, vielmehr müssen Maßnahmen getroffen werden, daß dem Gut ein bestimmter Impuls zum weiteren Abrutschen gegeben wird.Drive arrangement for spiral chutes of vertical dryers The invention relates to a drive arrangement for spiral grooves of vertical dryers. Such Spiral chutes are used to move the material, which is finely distributed on the sliding surfaces, into Bring intimate contact with the drying media, such as air or gases. to For this purpose, the media to be dried are placed on the working surfaces of the spiral chutes distributed, and the effective work surfaces receive a reciprocating or a unidirectional rotary motion. With the well-known spiral slides At the same time, an inclination of the helical slide tracks is provided, which is held in this way is that the angle of inclination of the tracks is smaller than the angle of friction of the goods on the surface. The goods do not slide down by themselves, they have to Measures are taken that the property a certain impulse to slip further is given.
Man hat zu diesem Zweck vorgeschlagen, den Drehvorgang von Zeit zu Zeit ZU unterbrechen. Beim Anhalten der Wendel rutschen rutscht das Gut infolge der ihm innewohnenden kinetischen Energie jeweils ein Stück weiter auf der Arbeitsfläche nach unten. For this purpose it has been suggested to stop the turning process from time to time Time to interrupt. When the helix is stopped, the material slips as a result its inherent kinetic energy a little further on the work surface downward.
Der Erfindung liegt die Aufgabe zugrunde, sowohl bei hohen als auch bei niederen Umfangsgeschwi;ndigketten den Fördereffekt beliebig zu regulieren, d. h. eine große oder kleine Fördermenge einstellen zu können. Mit dem Erfindungsgegenstand kann man den Fördereffekt den verschiedenen Beschaffenheiten des zu fördernden Gutes anpassen. Weiterhin wird der Vorteil erreicht, daß die Arbeitsflächen nicht unbedringt einen Neigungswinkel nach unten besitzen müssen. Die Arbeitsflächen können auch in einer horizontalen Ebene senkrecht zur Drehachse der Wendelrutschen stehen. Es genügen in diesen Fällen Offnungen in den Arbeitsflächen, durch die das Gut nach dem erteilten Impuls nach unten auf die nächste Arbeitsfläche fallen kann. The invention is based on the object, both at high and to regulate the conveying effect as required in the case of low circumferential speed chains, d. H. to be able to set a large or small delivery rate. With the subject of the invention one can determine the conveying effect of the different properties of the goods to be conveyed adjust. Furthermore, the advantage is achieved that the work surfaces are not necessarily penetrated must have a downward angle of inclination. The work surfaces can also stand in a horizontal plane perpendicular to the axis of rotation of the spiral chutes. It In these cases, openings in the work surfaces through which the goods can be fed are sufficient the given impulse can fall down onto the next work surface.
Erfindungsgemäß wird dies dadurch erreicht, daß die Bewegung der Arbeitsflächen durch einstellbare Anschläge ruckartig abstoppbar ist, die in die Bewegungsbahn der Arbeitsflächen von außen treten. According to the invention this is achieved in that the movement of the Work surfaces can be stopped abruptly by adjustable stops, which are in the Stepping the path of movement of the work surfaces from the outside.
Zusätzlich können in an sich bekannter Weise auch noch innere Anschläge an den Arbeitsflächen angeordnet sein, wobei durch eine Steuervorrichtung zu bestimmten Zeitpunkten die außerhalb der Bewegungsbahn der Arbeitsflächen liegenden Anschläge in die Bewegungsbahn der inneren Anschläge treten. In addition, internal stops can also be used in a manner known per se be arranged on the work surfaces, to be determined by a control device Times the stops lying outside the movement path of the work surfaces step into the path of movement of the inner stops.
Die äußeren und die inneren Anschläge können abgefedert und einstellbar sein, d. h. nachstellbar sein, um damit den Fördereffekt nicht zu beeinflussen. The outer and inner stops can be cushioned and adjustable be, d. H. be adjustable in order not to influence the conveying effect.
Die Steuerung der beweglichen Anschläge erfolgt vorzugsweise durch Steuerglieder, die von dem Hauptantrieb beeinflußt werden. The movable stops are preferably controlled by Control elements that are influenced by the main drive.
Man hat es dabei in der Hand, die Dauer der Einwirkung der äußeren Anschläge beliebig zu bestimmen, so daß die Wirkung des Stoppvorganges bezüglich der auftretenden Kräfte und der Zeitdauer regelbar ist. One has it in hand, the duration of the external influence Any stops to be determined, so that the effect of the stopping process with respect to the forces occurring and the duration can be regulated.
Die Erfindung ist in einem Ausfü'hrungsbeispiel in den Zeichnungen dargestellt. Es zeigt Fig. 1 eine Seitenansicht einer Antriebs anordnung für eine Wendel.rutsche von Vertikaltrocknern und Fig. 2 eine Ansicht von oben auf Fig. 1. The invention is shown in an exemplary embodiment in the drawings shown. It shows Fig. 1 a side view of a drive arrangement for a Spiral slide of vertical dryers and FIG. 2 is a view from above of FIG. 1.
1 ist der obere Teil eines Zylinders. Nach unten trägt der Zylinder die an sich bekannten Wendelrutschen eines Vertikaltrockners. Diese können ein-oder mehrgängig ausgebildet sein. Der Zylinder 1 führt entweder eine kontinuierlich drehende Bewegung in der Pfeilrichtung 2 aus oder efne hin- und herdrehende Bewegung von beispielsweise mehr als 90 oder 1800. Der Zylinder 1 erhält seinen Antrieb über einen Ring 3 und ein Antriebsrad 4. Die Ausbildiunag der Antriebselemente 3, 4 ist beliebig. Es können Zahnräder, Reibräder od. dgl. verwendet werden. Notwendig ist, daß zwischen zwei treibenden Elementen eine Rutschkupplung eingeschaltet ist. Das treibende Element, z. B. Zahnrad, kann auch in sich elastisch sein, d. h., zwischen Nahe und Radkranz ist eine Kelativbewegung möglich (Scheibe aus Gummi). 1 is the top of a cylinder. The cylinder carries downwards the known spiral chutes of a vertical dryer. These can be one or be multi-threaded. The cylinder 1 is either continuously rotating Movement in the direction of arrow 2 off or efne back and forth rotating movement of for example more than 90 or 1800. The cylinder 1 receives its drive from a ring 3 and a drive wheel 4. The training of the drive elements 3, 4 is any. Gears, friction wheels or the like can be used. Necessary is, that a slip clutch is switched on between two driving elements. That driving element, e.g. B. gear, can also be elastic in itself, i. i.e., between Relative movement is possible near and rim (rubber disc).
Der Zylinder 1 trägt einen Ring 5, auf welchem beispielsweise vier Anschläge 6, 7, 8 aufgebracht sind. The cylinder 1 carries a ring 5 on which, for example, four Stops 6, 7, 8 are applied.
Die Anschläge bestehen aus der Widerlagerfläche 6, einer Feder 7 und einer eigentlichen Prallfläche 8. Die Wirkung der Federn 7 ist regelbar.The stops consist of the abutment surface 6, a spring 7 and an actual impact surface 8. The action of the springs 7 can be regulated.
9 sind weitere Anschläge, von denen beispielsweise zwei Stück dargestellt sind, die in der Pfeilrichtung 10 radial in den Weg der Anschläge 8 zu gewissen Zeitpunkten gerückt werden können. Die Verschiebung der Anschläge 9 erfolgt durch Steuerglieder 11, 12. Die Bewegung der Steuerglieder 12 in der Pfeilrichtung 13 kann von dem Hauptantrieb 4 abgeleitet werden. 9 are further stops, of which, for example, two pieces are shown are that in the direction of arrow 10 radially in the path of the stops 8 to certain Points in time can be moved. The shifting of the stops 9 takes place through Control members 11, 12. The movement of the control members 12 in the direction of the arrow 13 can be derived from the main drive 4.
Die Wirkungsweise ist folgende: Sobald die Anschläge 9 in die Bewegungsbahn der Anschläge 6,7,8 gerückt werden, erfolgt beim Auftreffen der Prallflächen 8 auf die Anschläge 9 ein rluckweises Abstoppen des Zylinders 1. Das auf den Wendelrutschen aufliegende Gut rutscht infolge des Beharrungsvermogens damit ein Stück weiter nach unten. Das Abbremsen kann auf einem Umlaufweg des Rohres 1 von 3600 ein- oder mehrfach erfolgen. Man hat es in der Hand, durch Regelung bzw. Einstellung der Anschläge 6, 7, 8 bei jeder beliebigen Umfangsgeschwindigkeit des Zylindlers 1 den Fördereffekt einzustellen. The mode of operation is as follows: As soon as the stops 9 are in the path of movement the stops 6, 7, 8 are moved, takes place when the impact surfaces 8 hit the stops 9 a jerky stopping of the cylinder 1. That on the spiral chutes As a result of the inertia, the goods on top slide a little further below. The braking can be carried out one or more times on a circuit path of the pipe 1 from 3600 take place. You have it in your hand by regulating or setting the stops 6, 7, 8 at any circumferential speed of the cylinder 1 the conveying effect to adjust.
Nach Zurücktre,en der Anschlägq 9 ist die Blockierung des Zylinders 1 unterbrochen, und dieser führt seine Drehbewegung erneut aus.After stepping back the stop 9 is the blocking of the cylinder 1 interrupted, and this carries out its rotary movement again.
Mit der Einrichtung gemäß der Erfindung hat man es in der Hand, das zu behandelnde Gut längere oder kürzere Zeit in der Behandlungsvorrichtung zu belassen. Es können mehrere Wendelrutschen der beschriebenen Art in einer gemeinsamen Vorrichtung zusammengebaut sein, wobei die Wendelrutschen jeweils einen eigenen Antrieb oder einen gemeinsamen zentralen Antrieb erhalten können. With the device according to the invention you have it in hand that to leave items to be treated in the treatment device for a longer or shorter period of time. Several spiral chutes of the type described can be used in a common device be assembled, the spiral chutes each having their own drive or can receive a common central drive.
