Description
Mischmaschine mit Mischschnecke, insbesondere für Asche und ähnliches Gut. Bei Mischmaschinen mit Mischschnecke für staub- und brückenbildendes Gut, wie Asche, Beton u. dgl., treten Unzuträglichkeiten dadurch auf, daß bei Stauungen im Zuführungsraum, z. B. durch Einstürzen von aus dem Mischgut gebildeten Brücken plötzlich größere Mengen in die ;Mischschnecke hineinschießen und so ein Festfahren der Schnecke oder eine Überlastung des Antriebsmotors herbeiführen, oder daß durch die Stauungen eine richtige Beurteilung des Füllungsgrades der Schnecke und damit die richtige Beschickung der Maschine in Frage gestellt wird.Mixing machine with mixing screw, especially for ash and the like Good. For mixing machines with a mixing screw for dust and bridging material, such as Ash, concrete and the like, inconveniences arise in that when there is congestion in the Feed space, e.g. B. suddenly collapse of bridges formed from the mix Shoot larger quantities into the mixing screw, causing the screw to get stuck or cause an overload of the drive motor, or that by the congestion a correct assessment of the degree of filling of the screw and thus the correct one Loading of the machine is in question.
Nach der Erfindung werden diese Übelstände in einfacher Weise dadurch beseitigt, daß zwischen Förder- und Mischzone, also z. B. zwischen Förder- und Mischschnecke ein nicht mit Fördermitteln versehener Raum (Abb. i hei k) freibleibt, und daß nötigenfalls auf diesen Raum noch ein Schacht i aufgesetzt wird. Hierdurch wird erreicht, daß das von der Förderschnecke c geförderte Gut in den freien Raum durch das nachfolgende entgegen seiner Reibung auf dem Boden und an den Seitenwänden fortgeschoben werden muß, so daß es sich staut und den ganzen Querschnitt des Gehäuses ausfüllt. Hierdurch wird gleichzeitig verhindert, daß der sich im Zuführungsraum der Schnecke entwickelnde Staub durch den Mischraum in 'den Arbeitsraum übertritt.According to the invention, these inconveniences are thereby eliminated in a simple manner eliminates that between the conveying and mixing zone, so z. B. between conveyor and mixing screw a space not provided with funding (Fig. i hei k) remains free, and if necessary a shaft i is placed on this space. This achieves that the goods conveyed by the screw conveyor c into the free space through the following be pushed away against its friction on the floor and on the side walls must, so that it accumulates and fills the entire cross-section of the housing. Through this is at the same time prevented that the developing in the feed space of the screw Dust passes through the mixing room into the working area.
Wird mehr Gut durch die Förderschnecke in den freien Raum vorgeschoben, als die Mischschnecke verarbeiten kann, so tritt zunächst eine Zusammendrückung des Gutes in 'dem freien Raum ein, da es infolge des Fehlens von Fördermitteln, z. B. Schnecken, während seiner geradlinigen Fortbewegung nicht immer wieder aufgelockert wird. Genügt die Zusammendrückung nicht, so kann der Überschuß an Gut in den auf den freien Raum aufgesetzten Schacht nach oben ausweichen; er rutscht dann in Zeiten geringerer Zuführung wieder in den freien Raum zurück. Die Weite des Schachtes muß den Eigenschaften des zu verarbeitenden Gutes entsprechen und nötigenfalls so groß sein, wie der Durchmesser des Mischgefäßes, damit sich das Gut nicht darin festsetzen kann.If more material is pushed into the free space by the screw conveyor, than the mixing screw can process, compression occurs first of the goods in 'the free space, since due to the lack of funding, z. B. snails, not loosened again and again during its linear locomotion will. If the compression is not sufficient, the excess of good can be added to the evade the free space placed on the shaft upwards; it then slips at times lower feed back into the free space. The width of the shaft must correspond to the properties of the goods to be processed and, if necessary, as large be like the diameter of the mixing vessel, so that the goods do not get stuck in it can.
Abb. i und 2 zeigen j e einen Längsschnitt zweier verschiedener Ausführungsformen der Mischmaschine. d bedeutet das Schneckengehäuse, h die Schneckenwelle, c die Förderschnecke in der Zuführungszone, d die Mischflügel in der Mischzone, f das Wasserzuführungsrohr für die Befeuchtung des Gutes, das z. B. in bekannter Weise im Innern des Gehäuses als am Ende verschlossenes Rohr mit seitlichen öffnungen ausgebildet sein kann. g ist die Beschickungsöffnung, h die Austrittsöffnung für das Mischgut. i ist ein Schutzblech gegen das Eindringen von Fördergut in das Wellenlager. Der Mischraum ist in den Abbildungen so ausgebildet, daß sich überschießendes Befeuchtungsmittel am Boden sammeln kann, ohne in den Förderraum zurücktreten oder durch die Austrittsöffnung austreten zu können.Figs. I and 2 each show a longitudinal section of two different embodiments the mixer. d means the worm housing, h the worm shaft, c the Conveyor screw in the feed zone, d the mixing blades in the mixing zone, f the Water supply pipe for the moistening of the material that z. B. in a known manner inside the housing as a tube closed at the end with side openings can be formed. g is the loading opening, h the exit opening for the mix. i is a protective plate against the penetration of conveyed goods into the shaft bearing. The mixing space is designed in the figures so that excess humidifying agent can collect at the bottom without stepping back into the conveying chamber or through the outlet opening to be able to exit.
