Das Hauptpa/tent betrifft einen fahrbaren Brennofen für Kunststeine, bei welchem Ventilatoren vorgesehen sind, wekhe den für die Verbrennung erforderlichen Luftzug erzeugen.The main patent relates to a mobile kiln for artificial stones, in which fans are provided because they generate the draft necessary for combustion.

Die Beherrschung des Temperaturzustandes solcher Ventilatoren, welche in Rauch- und Feuergasen, laufen, ist außerordentlich schwierig. Es sind daher schon Versuche mit Kühlungen für solche Ventilatoren angestallt worden. Die vorgeschlagenen Flüssigkeitskühlungetn bedingen jedoch verwickelte Konstruktionen, weil das Kühlmittel sowohl stehende als auch bewegliche Teile kühlen muß.The control of the temperature state of such fans, which run in smoke and fire gases, is extremely difficult. There have therefore already been attempts with cooling for such fans been. The proposed liquid cooling, however, require intricate constructions, because the coolant must cool both stationary and moving parts.

Die Erfindung schlägt als Kühlmittel Luft voir und führt diese durch die hohle Welle des Ventilators ein. Der Austritt der' Kühlluft erfolgt dlurch die Nabe oder durch Öffnungen in den Ventilatorflügeln, die zu diesem Zweck hohl ausgebildet sind. Die hierbei eintretende Entspannung der Luft kann zur Erreichung eines zusätzlichen Kühleffektes ausgenutzt werden. Die Kühlluft kann ferner auch als zusätzliche Verbrennungsluft verwendet werden.The invention proposes air as a coolant and introduces it through the hollow shaft of the fan. The cooling air is discharged through the hub or through openings in the fan blades leading to this Purpose are hollow. The relaxation of the air that occurs here can be used to achieve an additional cooling effect can be used. The cooling air can also be used as additional combustion air be used.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigtAn exemplary embodiment of the subject matter of the invention is shown in the drawing. It shows

Fig. ι einen, senkrechten Schnitt durch einen fahrbaren Brennofen,Fig. Ι a vertical section through a drivable Kiln,

Fig. 2 einen senkrechten Schnitt durch einen Ventilator. Fig. 2 is a vertical section through a fan.

In den Fig. ι und 2 ist die Hohlwelle 2 eines Ventilators drehbar in einem Durchbruch, dar Gehäuseiwand eines fahrbaren Brennofens gelagert. Der Luftstrom 3 tritt entweder unter der Wirkung einer Pumpvorrichtung oder.unter der Wirkung der in den hohlen: Ventilatorflügeln ι auftretenden, einen Sog verursachenden Zentrifugalkräfte durch die Hohlwelle hindurch und tritt durch die Öffnungen 4 der Flügel 1 aus.In FIGS. 1 and 2, the hollow shaft 2 is a fan rotatably mounted in an opening, the housing wall of a mobile kiln. The airflow 3 occurs either under the action of a pumping device or under the action of those in the hollow: fan blades ι occurring, a suction causing centrifugal forces through the hollow shaft and exits through the openings 4 of the wing 1.

Es können ferner Öffnungen 5' in der Nabe 6 vorgesehen werden, um die Kühlwirkung nach. Maßgabe der Erfordernisse! über den gesamten Ventilator zu verteilen, oder auch zu dem Zweck, um beistimmte Teile, die besonders stark erhitzt werden, stärker zu kühlen als andere Teile.Furthermore, openings 5 ′ can be provided in the hub 6 be to the cooling effect after. According to the requirements! over the entire fan distribute, or also for the purpose of certain parts that are particularly heated, to be stronger cool than other parts.

In den meisten, Fällen wird auf eine Vorpressung der Luft verzichtet werden können, da. die hohlen Ventilatorflügel auf den Luftstrom die gleiche Wirkung ausüben wie bei den bekannten Kreiselverdich-Wagenförmiger Brennofen für TonwarenIn most cases, air pre-compression can be dispensed with. the caves Fan blades exert the same effect on the air flow as with the known centrifugal compressor car-shaped Kiln for pottery

PATENTANSPRÜCHE:PATENT CLAIMS: 1. Brennofen für Tonwaren, bestehend aus einem Wagen mit seitlich der Standbahn des Brenngutstapels angeordnetem Druckventilator, nach Anspruch 7 des Patentes 842 927, dadurch, gekennzeichnet, daß die in an sich bekannter Weise hohl ausgebildete Ventilator welle (2) in die Hohlräume der hohl ausgebildeten Ventilatorflügel (1) mündet, welche an ihren freien Enden geschlossen, dagegen an den blasseitigen Stirnflächen mit Luftaustrittsöffnungen (4) versehen sind.1. Kiln for pottery, consisting of a trolley with the stand track of the stack of kiln to the side arranged pressure fan, according to claim 7 of patent 842 927, characterized in that, that the fan shaft (2), which is hollow in a manner known per se, into the cavities the hollow fan blade (1) opens, which are closed at their free ends, on the other hand with air outlet openings on the pale-side end faces (4) are provided. 2. Brennofen nach Anspruch 1, dadurch gekennzeichnet, daß in der blasseitigen Abschlußwand der Ventilatorwelle axial gerichtete Luftaustrittsöffnungen (5) vorgesehen sind.2. Kiln according to claim 1, characterized in that that axially directed air outlet openings in the blow-side end wall of the fan shaft (5) are provided. 3. Brennofen nach Anspruch 1 oder 2, dadurch ..gekennzeichnet, daß an den Übergängen von der Hohlwelle zu den Hohlflügeln der Durchgangsquerschnitt sich zunächst allmählich verengt, um sich dann plötzlich zu erweitern, derart, daß das Ansaugen der Luft durch ihre Zentrifugailbeischleunigung in den. Hohlnügeln; erfolgt (Fig. 2).3. Kiln according to claim 1 or 2, characterized .. characterized in that at the transitions from the Hollow shaft to the hollow wings of the passage cross-section initially gradually narrows to then suddenly expand in such a way that the air is sucked in by its centrifugal acceleration in the. Hollow hangings; takes place (Fig. 2). In Betracht gezogene Druckschriften: Französische Patentschriften. Nr. 392 565, 897 034; USA.-Patentschrift Nr. 2 220 420.Documents considered: French patents.
