Description
Heißgasaxialventilator Die Erfindung betrifft ein Heißgasaxialgebläse mit Elektromotor, der in einem innerhalb des Gebläsegehäuses befindlichen, vom Heißgas umströmten Schutzgehäuse angeordnet ist und von Kühlluft, die das Gebläse durch eine von außerhalb des Gebläsegehäuses radial ins Schutzgehäuse führende Rohrleitung ansaugt, um- und durchströmt wird.Hot gas axial fan The invention relates to a hot gas axial fan with an electric motor, which is located inside the fan housing, from the hot gas surrounded by a protective housing and by cooling air, which the fan through a pipeline leading radially into the protective housing from outside the fan housing is sucked in, flowed around and through.
Bei den bekannten Gebläsen dieser Art wird die Kühlluft vom Heißgas-Gebläserad selbst angesaugt, also ins Heißgas gefördert. Wenn solche Mischung des Heißgases mit der Kühlluft unzulässig ist, wenn also die Kühlluft nicht vom Gebläserad gefördert werden darf, dann pflegt man sie mittels eines eigenen Kühlluft-Gebläserades des Elektromotors anzusaugen und durch eine besondere Leitung nach außerhalb des Heißgasstromes abzuführen, das ist z. B. von einem Trockenkammer-Umwälzgebläse axialer Bauart bekannt, bei dem die Kühlluftzufuhr- und -abfuhrleitungen durch zwei zueinander konzentrische, zum Gebläserad koaxiale Rohre gebildet werden (das Heißgas strömt dort erst kurz vor dem Axialrad, und zwar von der Seite zu). Bekannt ist solche Trennung des Kühlluftstromes vom Heißgasstrom auch von einem Axialgebläse, bei dem der Motor nicht im Schutzgehäuse, sondern ganz außerhalb des Gebläsegehäuses angeordnet ist und im Schutzgehäuse sich nur ein Wellenlager und das Kühllüfterrad befindet; dort ist das Schutzgehäuse mit der Außenluft durch zwei einander diametral gegenüber angeordnete Rohre, nämlich je eines für die Zufuhr und die Abfuhr der Kühlluft, verbunden.In the known fans of this type, the cooling air is from the hot gas fan wheel sucked in, i.e. conveyed into the hot gas. When such mixture of hot gas with the cooling air is impermissible, i.e. if the cooling air is not conveyed by the fan wheel is allowed to be, then you maintain them by means of the cooling air fan of the Electric motor to suck in and through a special line to the outside of the hot gas flow discharge, this is z. B. known from a drying chamber circulation fan of axial design, in which the cooling air supply and discharge lines are provided by two concentric, pipes coaxial to the fan wheel are formed (the hot gas only flows there briefly in front of the axial wheel, from the side to). Such separation of the cooling air flow is known from the hot gas flow also from an axial fan in which the motor is not in the protective housing, but is arranged completely outside of the fan housing and in the protective housing itself only one shaft bearing and the cooling fan wheel is located; there is the protective housing with the outside air through two diametrically opposed tubes, namely one each for supplying and removing the cooling air.
Die Erfindung will solche Trennung des Kühlluftstromes vom Heißgasstrom auch bei einem Gebläse der eingangs genannten Art bewirken und will die Zufuhr- und Abfuhrkanäle mit möglichst einfachen Mitteln bilden.The invention aims to separate the flow of cooling air from the flow of hot gas also cause a blower of the type mentioned and wants the supply and form discharge channels with the simplest possible means.
Die Erfindung besteht darin, daß in an sich bekannter Weise die Kühlluft durch ein eigenes Kühllüfterrad des Elektromotors angesaugt und, getrennt vom Heißgasstrom, durch eine eigene Leitung abgeführt wird, ferner daß diese Abfuhr- und die Zufuhrleitung von einem einzigen Rohr mit einer ebenen Längs-Trennwand gebildet werden und daß diese Trennwand sich auch durch den Innenraum des Schutzgehäuses erstreckt, an der Kühllüfterhaube des Motors anliegt und dort mit einer der Saugöffnung der Kühllüfterhaube entsprechenden Öffnung versehen ist.The invention consists in that the cooling air in a manner known per se sucked in by the electric motor's own cooling fan wheel and, separated from the hot gas flow, is discharged through its own line, also that this discharge and the supply line be formed by a single tube with a flat longitudinal partition and that this partition also extends through the interior of the protective housing on which Cooling fan cover of the motor and there with one of the suction opening of the cooling fan cover corresponding opening is provided.
In der Zeichnung bedeutet 1 das Heißgasgebläserad 2 den Motorwellenstumpf, 3 den Motor mit Kühllüfterrad und üblicher Kühllüfterhaube, 4 das Schutzgehäuse, 5 das Heißgasgebläsegehäuse, 6 das die Kühlluftzufuhr- und -abfuhrleitungen enthaltende Rohr, 7 die das Rohr in jene beiden Leitungen trennende und sich durch das Schutzgehäuse erstreckende Trennwand und 8 die Öffnung in der Trennwand, die der Saugöffnung der Kühllüfterhaube entspricht.In the drawing, 1 means the hot gas blower wheel 2 the motor shaft stub, 3 the motor with cooling fan wheel and normal cooling fan cover, 4 the protective housing, 5 the hot gas blower housing, 6 the one containing the cooling air supply and discharge lines Tube, 7 which separates the tube into those two lines and runs through the protective housing extending partition and 8 the opening in the partition, which is the suction opening of the Cooling fan cover.
