Description

Antriebsvorrichtung für Drehöfen Beim Betrieb von Drehöfen aller Art, die zum Schmelzen oder Reinigen von Eisen oder Metallen dienen, tritt während Lies Einschmelzens, wenn das Gut noch nicht ganz geschmolzen .ist, häufig ein Ankleben an der feuerfesten Masse des Ofens ein. Dadurch wird ein schweres Arbeiten des Rollwerkes hervargerufen, da die einseitig am Futter hängende Masse den Ofen entgegengesetzt zu drehen versucht.Drive device for rotary ovens When operating rotary ovens of all types, which serve to smelt or purify iron or metals occurs during lies Melting down when the product has not yet completely melted, often sticking on the refractory mass of the furnace. This makes the scrollwork difficult to work with called out because the mass hanging on one side of the lining is opposite to the oven tried to turn.

Besonders in den Fällen, in denen die Drehung des Ofens durch den Antrieb der Verlagerungsrollen hervorgerufen wird, also durch reinen Reibungsschluß, kann es vorkommen, daß der Ofen auf der Antriebsralle rutscht, entgegengesetzte Drehrichtung annimmt und starke Schläge in der Antriebsvorrichtung verursacht.Especially in those cases where the rotation of the furnace is caused by the Drive of the displacement rollers is caused, i.e. by pure frictional engagement, it can happen that the stove slips on the drive rail, opposite Direction of rotation assumes and causes strong blows in the drive device.

Aber auch bei gewaltsamem Durchdrehen treten leicht Beschädigungen des feuerfesten Futters ein, indem schwerere Stücke der Beschickung dauernd fallend das Futter zertrümmern. Durch am Ofen angeordnete Schaltfinger hat man bereits Öfen eine Schaukelbewegung erteilt. Hierbei muß man sich mit einem ein für allemal festgelegten D.reh-,vinkel begnügen, unabhängig von jeweiliger Größe und Zustand des Einsatzes. Gerade aber diese stets wechselnden Bedingungen erfordern einen stets wechselnden Drehwinkel, um die beste Wirkung jeweils zu erzielen.But even if it is spun violently, damage can easily occur of the refractory lining by continuously falling heavier pieces of the load smash the lining. With switching fingers arranged on the furnace you already have furnaces given a rocking motion. Here you have to settle for a once and for all set That means that you are satisfied with the rotation and angle, regardless of the size and condition of the insert. But it is precisely these ever-changing conditions that require an ever-changing one Rotation angle to get the best effect in each case.

Erfindungsgemäß wird der an sich bekannten Schaukelbewegung des Ofens dadurch eine besondere Ausgestaltung gegeben, daß diese Schauk.elhewegung selbsttätig gesteuert wird, indem die Drehrichtungsumkehrung jedesmal dann erfolgt, wenn die Rollwerksbelastung eine solche Größe erreicht hat, bei der gefährliche Beanspruchungen von Getriebe oder Futter noch nicht eintreten können.According to the known rocking motion of the furnace This gives a special design that this Schauk.elhewegung automatically is controlled by reversing the direction of rotation every time the Rolling mechanism load has reached such a size that dangerous loads transmission or chuck cannot yet enter.

Mit dem Antriebsmotor des Rollwerks ist z. B. ein durch die Stromstärke gesteuertes Relais verbunden (Amperemeter), v-elches in der eben angegebenen Belastungsgrenze einen Kontakt betätigt, durch den der Rolltll#)tor stillgesetzt und ihm nach einer bestimmten Zeit die entgegengesetzte Drehrichtung erteilt wird.With the drive motor of the scrollwork z. B. one by the amperage controlled relay connected (ammeter), v-elches in just that specified load limit actuates a contact through which the roller shutter door stopped and it rotates in the opposite direction after a certain time is granted.

Statt eines Amperemeters kann beispiels-«eise auch die thermische Auslösung der Schützensteuerung dienen. Durch einen Bimetallstrcifen geht ein Teil des Motorstromes; bei wachsender Stromstärke erwärmt sich der Bimetallstreifen, krümmt sich und verursacht eine Unterbrechung des die Schütz°nspule erregenden Stromes; der Motor wird abgeschaltet. Durch Zwischenscbalturg eines zeitverzögernden und Umschaltrelais wird dann anschließend das zu"ehörige Wendeschütz tingescbaltet, das den Motor auf entgegeiigesetzte Drehrichtung steuert.Instead of an ammeter, for example, the thermal Serve to trigger the contactor control. A part goes through a bimetal strip the motor current; the bimetal strip heats up as the current increases, bends and causes the current energizing the contactor coil to be interrupted; the engine is switched off. By Zwischencbalturg a time-delaying and The changeover relay is then connected to the reversing contactor belonging to it, that controls the motor in the opposite direction of rotation.

Die aus der Abbildung ersichtliche Einricbtullg arbeitet folgendermaßen: Wenn der Motor t über das Getriebe 2 dein Ofen 3 antreibt, erzeugt der Ofen in der gezeichneten Stellung ein links gerichtetes Drehmoment, verursacht durch die ei@aeitig im Ofen hängende Masse 4.. Der Zeiger des Amperemeters 5 steigt laufend höher, bis er an den Kontakt 6 anstößt, der das Schütz S des Motors über das Umschaltrelais 7 sowie dic Spulen 9 und über das Zeitrelais 1o den Motor nach kurzer Zeit in entgegengesetzter Drehrichtung in Tätigkeit setzt. Statt der Steuerung der Relais durch das Amperemeter 5 kann diese auch durch die thermische Auslösung 11 erfolgen.The setup shown in the figure works as follows: When the motor t drives your furnace 3 via the gearbox 2, the furnace produces in the shown position a left-directed torque, caused by the egg @ aeiten mass hanging in the oven 4 .. The pointer of the ammeter 5 rises continuously higher until it hits contact 6, which connects the contactor S of the motor via the changeover relay 7 as well as the coils 9 and via the time relay 1o the motor after a short time in the opposite direction Direction of rotation in action. Instead of controlling the relays through the ammeter 5, this can also be done by thermal release 11.

Sobald der Einsatz so weit teigig oder flüssig geworden ist, daß durch sein Anhängen am Futter kein großes Drehmoment mehr entstehen kann, wird der Ofen von selbst i eine ununterbrochene Drehbewegung annehme:n, da das Triebwerk nur innerhalb der zulässigen Grenzen belastet wird.As soon as the insert has become so doughy or liquid that through When it is attached to the chuck, a large torque can no longer arise, the furnace becomes by itself i assume an uninterrupted rotary motion: n, since the engine is only within the permissible limits is loaded.

Es nimmt der Ofen demnach kurz nach der Beschickung nur einen kleinen Ausschlagwinkel an, der sich allmählich vergrößert wie der Eilsatz flüssig wird, um schließlich in eine fortlaufende Drehbewegung überzugehen.The furnace will only take a small one shortly after loading Deflection angle, which gradually increases as the express sentence becomes fluid, to finally change into a continuous rotating movement.
