Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von Fasern, insbesondere aus Glas, Schlacke oder sonstigem wärmebildsamem, anorganischem Material, wobei ein Strahl geschmolzenen, flüssigen Materials durch die Fliehkraftwirkung einer rotierenden Scheibe in feine Fäden umgewandelt wird. Bei den bisher bekannten.Verf ahren und Vorrichtungen für diesen Fabrikationszweig erhielt man die Fasern als ringförmige Strähnen, welche auf einem Tisch abgelegt wurden, wo sie dann mit Messern oder Scheren intermittierend aufgeschnitten und entfernt wurden. Auch wurden in einer Horizontalebene oder in einer Vertikalebene rotierende Kreissägeblätter und Messer verwendet, um die Strähnen aufzuschneiden und die Fasern kontinuierlich zu entfernen. Bei diesen Vorrichtungen lagert sich das Material zum Teil auf den Blättern bzw. Messern ab.The invention relates to a device for the production of fibers, in particular from glass, Slag or other heat-forming, inorganic material, whereby a jet of molten, liquid material is converted into fine threads by the centrifugal force of a rotating disk. The fibers were obtained with the previously known methods and devices for this branch of manufacture as ring-shaped strands, which were placed on a table, where they were then opened with knives or scissors were cut open and removed intermittently. Also were in a horizontal plane or in a Vertical rotating circular saw blades and knives are used to cut the strands and the Remove fibers continuously. In these devices, the material is partly deposited on the Scroll or knives off.

Des weiteren ist ein Verfahren bekannt, bei dem die von dem Schleuderkörper abfallenden Fasern einem Druckmittelstrom ausgesetzt werden, der aus zwei oberhalb und unterhalb des Schleuderkörpers austretenden Luftströmen, die die Fasern erfassen, gebildet wird. Nach Durchtritt durch den Luftstrom fallen die Fasern herab und können sich auf der Unterlage in unerwünschter Weise zusammenballen.Furthermore, a method is known in which the falling from the centrifugal body fibers one Pressure medium flow are exposed to the exiting from two above and below the centrifugal body Air currents engaging the fibers is formed. After passing through the air stream, they fall Fibers fall down and can agglomerate on the surface in an undesirable manner.

Die Erfindung hat nun eine neue Vorrichtung zum Gegenstand, bei der die-den bekannten Verfahren und Vorrichtungen anhaftenden Nachteile nicht auftreten. Sie ist dadurch gekennzeichnet, daß unterhalb einer Schleuderscheibe auf deren Welle eine Gebläseyorrichtung angeordnet ist, die aus zwei sich überlappenden Trichtern besteht; zwischen diesen befinden sich Gebläseschaufeln, welche den ersten Luftstrom erzeugen, der unter einem Winkel zur Senkrechten abwärts gerichtet ist. Der untere Trichter besitzt vorzugsweise an seinem unteren Rande einen kreisförmigen Flansch, der nach außen gerichtet und an seiner Unterseite mit Gebläseschaufeln versehen ist, um den zweiten, horizontal gerichteten Luftstrom zu erzeugen, welcher unter anderen Dingen die Aufgabe hat, die Fasern daran zu hindern, am Boden des das Gebläserad umgebenden Mantels haftenzubleiben.The invention now has a new device as an object in which the known methods and Devices inherent disadvantages do not occur. It is characterized in that below one Centrifugal disc on whose shaft a fan device is arranged, which consists of two overlapping Funnels consists; between these are fan blades, which the first air flow that is directed downwards at an angle to the vertical. The lower funnel preferably has at its lower edge a circular flange which is directed outwards and at its The underside is provided with fan blades to generate the second, horizontally directed air flow, which, among other things, has the task of preventing the fibers from reaching the bottom of the fan wheel to stick to the surrounding jacket.

Die vorliegende Erfindung wird nunmehr nachstehend ausführlicher beschrieben werden, und zwar unter Bezugnahme auf die Zeichnung, welche eine erfindungsgemäße Vorrichtung im senkrechten Querschnitt darstellt.The present invention will now be described in more detail below, namely below Reference to the drawing, which shows an inventive Represents device in vertical cross section.

Die Zeichnung zeigt einen Schmelzofen 2 für das anorganische Material, aus welchem die Fasern hergestellt werden.

halb der Scheibe 6 ein Gebläserad, welches aus den beiden konischen Trichtern 8 und 10 besteht, deren Neigungswinkel etwas verschieden voneinander sind. Der obere Trichter 8 ist teilweise über den unteren Trichter 10 geschoben, und in dem Zwischenraum zwischen diesen beiden Trichtern, die sich also teilweise überlappen, befinden sich die Gebläseschaufeln 16. Der Zweck des oberen konischen Trichters 8 ist der, den Faserstrom zu führen bzw. zu richten und die Fasern an der Berührung mit den Gebläseschaufeln zu hindern. Der Trichter 8 schützt also die Gebläseschaufeln vor dem Verschleiß. Das Gebläserad wird von einem Mantel 12 umgeben; letzterer ist als Gebläsegehäuse angeordnet und mit einer Auslaßöffnung 14 für die Fasern und die dieselben fördernden Luftströme versehen. Der untere Rand des unteren konischen Trichters ist mit einem nach auswärts gerichteten Flansch 22 versehen, und an der Unterseite des besagten Flansches sind Gebläseschaufeln 24 angebracht, um einen horizontalen Luftstrom längs des Bodens des Mantels 12 zu erzeugen und damit die Fasern daran zu hindern, mit dem Boden in Berührung zu kommen und an demselben haftenzubleiben. Bei der Herstellung anorganischer Fasern ist es oft erwünscht, die Fasern mit einer dünnen Schicht eines Bindemittels, Gleitmittels oder eines ähnlichen Mittels zu überziehen. Für den Zusatz eines derartigen Mittels in flüssigem Zustande, beispielsweise ge-half of the disc 6, a fan wheel, which consists of the two conical funnels 8 and 10, whose Angles of inclination are slightly different from each other. The upper funnel 8 is partially above the lower one Funnel 10 pushed, and in the space between these two funnels, which are therefore partially overlap, there are fan blades 16. The purpose of the upper conical funnel 8 is that of guiding or directing the flow of fibers and keeping the fibers in contact with the fan blades to prevent. The funnel 8 thus protects the fan blades from wear. The fan wheel will surrounded by a jacket 12; the latter is arranged as a fan housing and has an outlet opening 14 for the fibers and the air streams promoting them. The lower edge of the lower conical Hopper is provided with an outwardly directed flange 22, and at the bottom of the said flange, fan blades 24 are attached to a horizontal air flow along the To generate the bottom of the jacket 12 and thus to prevent the fibers from coming into contact with the ground to come and stick to it. In the manufacture of inorganic fibers it is often it is desirable to coat the fibers with a thin layer of a binder, lubricant, or the like Means to overcoat. For the addition of such an agent in a liquid state, for example,

schmolzen, gelöst oder emulgiert, ist die in der Zeichnung dargestellte Vorrichtung mit dem folgenden Bestandteil versehen:melted, dissolved, or emulsified, is the one in the drawing provided the device shown with the following component:

In dem unteren konischen Trichter 10 ist ein Flansch 18 angeordnet, und zwar so, daß zwischen diesem Flansch und der Innenwandung des Trichters ein keilförmiger Kanal gebildet wird, welcher unten dicht an der Innenwandung des Trichters 10 kleine Zwischenräume bzw. öffnungen hat. In dem besagten Kanal oder oberhalb desselben befindet sich die Auslaßöffnung eines Rohres 20 für die Zuleitung eines flüssigen Bindemittels, Gleitmittels oder eines ähnlichen Mittels. Die Flüssigkeit fließt an der Innenwandung des konischen Trichters 10 zu den Gebläseschaufeln 24 herab, wird durch die besagten Gebläseschaufeln 24 zusammen mit dem horizontalen Luftstrom herausgeschleudert und kommt infolgedessen in Berührung mit dem von oben kommenden Faserstrom. Eine ähnliche Speisevorrichtung für ein Gleit- oder ein Bindemittel kann natürlich auch in dem oberen konischen Trichter angeordnet werden, wobei das betreffende Mittel durch die Gebläseschaufeln 16 herausgeschleudert wird. Die in der Zeichnung dargestellte Vorrichtung arbeitet in der folgenden Weise:In the lower conical funnel 10, a flange 18 is arranged, in such a way that between This flange and the inner wall of the funnel a wedge-shaped channel is formed, which is below close to the inner wall of the funnel 10 has small spaces or openings. In the said Channel or above the same is the outlet opening of a pipe 20 for the supply of a liquid binder, lubricant or a similar agent. The liquid flows on the inner wall of the conical hopper 10 down to the fan blades 24 is through said fan blades 24 is thrown out together with the horizontal air flow and comes as a result in contact with the fiber stream coming from above. A similar feeding device for a Lubricant or a binding agent can of course also be arranged in the upper conical funnel, whereby the agent in question is thrown out by the fan blades 16. The one shown in the drawing Device works in the following way:

Das anorganische, wärmebildsame Material wird in dem Ofen 2 geschmolzen und fließt als feiner Strahl durch die Bodenöffnung 4 auf die sich rasch drehende Fliehkraftscheibe 6, auf welcher das Material in feine Fäden oder Fasern umgewandelt wird, welche von der Scheibe abgeschleudert werden. ±\ach Verlassen des Randes der Scheibe verlieren die Fasern bald ihre horizontale Geschwindigkeit und fallen abwärts, wobei sie den durch die Saugwirkung der Gebläseschaufeln 16 erzeugten Luftstrom passieren, durch welchen die Fasern gekühlt werden. Die Fasern werden dann durch den oberen konischen Trichter 8 etwas mehr nach außen gerichtet und durch den Luftstrom erfaßt, welcher durch die Gebläseschaufeln 16 erzeugt und unter einem Winkel zur Senkrechten abwärts gedrückt wird. Dadurch haben die Fasern niemals eine Gelegenheit zu der Bildung von Strähnen, sondern nehmen die Form von Stapelfasern an, die durch den Luftstrom an den beiden konischen Trichtern 8 und 10 vorbeigeleitet und dann dem horizontalen Luftstrom, in welchem ein Gleit- oder ein Bindemittel dispergiert sein kann, ausgesetzt werden; schließlich werden sie durch die Öffnung 14 ausgetragen.The inorganic, heat-forming material is melted in the furnace 2 and flows as a fine jet through the bottom opening 4 onto the rapidly rotating centrifugal disk 6, on which the material is converted into fine threads or fibers which are thrown off the disk. After leaving the edge of the disk, the fibers soon lose their horizontal speed and fall downwards, passing through the air flow generated by the suction effect of the fan blades 16, by which the fibers are cooled. The fibers are then directed somewhat more outwardly by the upper conical funnel 8 and are caught by the air flow which is generated by the fan blades 16 and pressed downwards at an angle to the vertical. As a result, the fibers never have an opportunity to form strands, but instead take the form of staple fibers that are guided by the air flow past the two conical hoppers 8 and 10 and then the horizontal air flow in which a lubricant or a binding agent is dispersed can be suspended; finally, they are discharged through the opening 14.

Durch die erfindungsgemäße Vorrichtung erhält man einen gleichmäßigen Strom eines Stapelfaserprodukts mit sehr guten Eigenschaften für die Herstellung von Filz und Platten.The device according to the invention provides a uniform flow of a staple fiber product with very good properties for the production of felt and panels.
