Description

Schleudermaschine mit einer in der mittleren Kappe der Schleudertrommel eingebauten elektrischen Antriebsmaschine Es ist vorgeschlagen worden, im Innern der sich nach oben erstreckenden Kappe einer Schleudertrommel eine Antriebsmaschine, z. B. einen Elektromotor, einzubauen, dessen senkrecht stehende Welle auch die Schleudertrommel trägt.Spin machine with one in the center cap of the spin drum built-in electric prime mover It has been suggested inside the upwardly extending cap of a centrifugal drum a drive machine, z. B. to install an electric motor, the vertical shaft of which also the centrifugal drum wearing.

Ferner sind Siebtrommeln bekannt, die mit der Trommelnabe durch ventilatorartig wirkende Rippen verbunden sind, um einen zur Belüftung des Schleudergutes dienenden Luftstrom in axialer Richtung zu erzielen.Furthermore, sieve drums are known, which with the drum hub through a fan-like acting ribs are connected to a serving to ventilate the material to be centrifuged To achieve air flow in the axial direction.

Die Erfindung besteht demgegenüber darin, auf der Innenfläche der die Antriebsmaschine umgebenden Kappe schrauben- oder schaufelartige Rippen anzuordnen, die eine Fortsetzung der oberen Rippen bilden und die eine wirksame Außenkühlung der Antriebsmaschine gewährleisten.The invention is, on the other hand, on the inner surface of the to arrange screw-like or blade-like ribs surrounding the drive machine, which form a continuation of the upper ribs and which provide effective external cooling the drive machine.

Auf der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung im Längsschnitt an einer selbstentleerenden Pendelschleuder dargestellt.The drawing shows an exemplary embodiment of FIG Invention shown in longitudinal section on a self-emptying pendulum slingshot.

Der Läufer eines Elektromotors a mit senkrechter Welle b ist im Innern der mit dem Trommelsieb d verbundenen Kappe c untergebracht, die durch schraubenförmig ge-@vundene, speichenartige Rippen e mit der Antriebswelle b der Schleudertrommel verbunden ist. Die Rippen e, die bei umlaufender Schleudertrommel einen nach oben gerichteten Windkühlstrom erzeugen, wobei sie die Luft durch den Motor a hindurch ansaugen, haben erfindungsgemäß auf der Innenfläche der Kappe c, also im Ringraum zwischen der Kappe c und dem Motorgehäuse Fortsetzungen e', so daß auch das Motorgehäuse von außen gekühlt wird.The rotor of an electric motor a with a vertical shaft b is inside the cap c connected to the drum screen d housed by the helical Rounded, spoke-like ribs e with the drive shaft b of the centrifugal drum connected is. The ribs e, the one facing up when the centrifugal drum rotates Generate directed wind cooling flow, whereby they the air through the engine a suck, have according to the invention on the inner surface of the cap c, so in the annular space between the cap c and the motor housing continuations e ', so that the motor housing is cooled from the outside.

Die durch den Motor cc strömende Kühlluft, die durch eine Öffnung g des aufgesetzten Blechkegels lt , abgeführt wird, kann. nebenbei bemerkt, in bekannter Weise auch noch durch einen auf -der Motorwelle b angeordneten Luftflügel f beschleunigt werden.By the motor cc flowing cooling air through an opening g of the mounted lt sheet metal cone which is discharged can. Incidentally, can also be accelerated in a known manner by an air blade f arranged on the motor shaft b.
