Description
Zellenraddosiergerät für staubförmige bis körnige SchüttgüterRotary feeder for powdery to granular bulk materials
mit Einrichtung zur schnellen Reinigung Der Erfindung liegt die Aufgabe zugrunde, ein Zellenrad-Dosiergerät zu konstruieren, das eine schnelle und gute Reinigung ermöglicht.with device for quick cleaning The object of the invention is based on constructing a rotary feeder that is fast and good Cleaning made possible.
Es gibt zwar bereits Scheibendosiergeräte die sich verhältnismäßig schnell reinigen iassen, die gesamte Konstruktion ist jedoch sehr aufwendig. Desweiteren ist auch bekannt, die weniger aufwendigen Zellenräder zur Dosierung zu verwenden. Als Nachteil bei diesen wird jedoch wiederum die zeitaufwendige Reinigung aller mit dem Dosiergut in Berührung kommenden Teile empfunden und dies ganz besonders dann, wenn nacheinander verschiedene Farben dosiert werden sollen und bei Farbwechsel keine Reste im Gerät oder Staubreste an den Wänden haften bleiben dürfen.There are already disc dosing devices that are proportionate Can be cleaned quickly, but the entire construction is very complex. Further it is also known to use the less complex cell wheels for dosing. However, the time-consuming cleaning of all is again a disadvantage of these parts coming into contact with the dispensing material felt and this is especially true when different colors are to be dosed one after the other and when changing colors no residues in the device or dust residues may stick to the walls.
Das Zellenrad-Dosiergerät soll mit wenigen Handgriffen ohne Werkzeug zerlegbar sein, sodaß die Teile, die mit dem Dosiergut direkt in Berührung kommen, soweit als möglich auswechselbar sind, sodaß diese bei Bedarf auch noch nachträglich naß gereinigt werden können.The rotary feeder should take a few simple steps without tools can be dismantled so that the parts that come into direct contact with the dosing material are exchangeable as far as possible, so that they can also be retrofitted if necessary can be cleaned wet.
Figur 1 zeigt ein Zellenrad-Dosiergerät für rieselfähiges Gut Figur 2 das Zellenrad im Schnitt und Figur 3 den Schnitt a.b durch die Figur 2. Zu erkennen sind der Vorratstrichter 1 mit der darunter angeordneten Schleuse 2 und der Antriebsmotor 3 mit Kupplungshülse 4, der Abiauftrichter 5 und das Handrand 6, das zu dem hier nicht im Detail datgestellten Schnellverschluß gehört.Figure 1 shows a cellular wheel metering device for pourable material figure 2 shows the cellular wheel in section and FIG. 3 shows the section a.b through FIG. 2 are the storage hopper 1 with the lock 2 arranged below it and the drive motor 3 with coupling sleeve 4, the funnel 5 and the hand edge 6, which is here quick release not included in detail.
Das Zellenrad selbst ist in den Figuren 2 + 3 im Detail dargestellt.The star feeder itself is shown in detail in FIGS. 2 + 3.
Zu erkennen sind der Zellenradkern 7, die beiden Seitenwände 8 + 8 a mit den beiden Halteringen 9 + 9a, die linke Seitenwand mit 2 Vertiefungen 10 zur Aufnahme von je 1 Mitnehmerstift der Kupplung, die Rillen 11, die als Labtrintdichtung dienen, die Bohrung 12 zur Aufnahme des Bolzens eines Schneliverschlusses und die Zellenstege 13.The bucket wheel core 7 and the two side walls 8 + 8 can be seen a with the two retaining rings 9 + 9a, the left side wall with 2 recesses 10 to accommodate 1 driving pin of the coupling, the grooves 11, which act as a labtrint seal serve, the bore 12 for receiving the bolt of a quick release and the Cell bars 13.
Aus der Beschreibung der Figuren ist nun leicht zu erkennen, daß das ganze Zellenrad nach öffnen des Schnellverschlusses in seine Einzelheiten ohne Werkzeug zu Reinigungszwecken rerlegt werden kann.From the description of the figures it is now easy to see that the whole cellular wheel after opening the quick release in its details without tools can be laid down for cleaning purposes.
Figur 4zeigt den Zellensteg 13 in der Draufsicht. Erkennbar sind die Ausnehmungen 14 + 14 a, in die die Ringe 9 + 9 a eingreifen, um so daE Herausfallen zu verhindern. Eine weitere mögliche Variation des Zellensteges 13 zeigt Figur 5 mit vorstehenden Teilen am Fuß des Zellensteges 15. Von besonderem Vorteil ist es, wenn die Zellenstege 13 aus ei nem einem elastischen,abriebfesten Werkstoff z.B.Figure 4 shows the cell web 13 in plan view. They are recognizable Recesses 14 + 14 a, in which the rings 9 + 9 a engage, so that they fall out to prevent. Another possible variation of the cell web 13 is shown in FIG. 5 with protruding parts at the foot of the cell web 15. It is particularly advantageous to if the cell webs 13 are made of an elastic, abrasion-resistant material, e.g.
Vulkolan bestehen. Wenn sich in dem Dosiergut auch größere körnige Teile befinden, so können diese Zellenstege jeweils dann nachgeben, wenn sich bei der Drehung des Zellenrades gelegentlich größere Teile an der Schnittkante zwischen Zellenradgehäuse und Zellenrad-Steg befinden. Ein zerschneiden dieser Teile wie bei Zellenrädern normal üblich, ist bei dieser Ausführung nicht erforderlich.Vulkolan exist. If there are also larger granular ones in the material to be dosed Parts are located, so these cell webs can give way when there is the rotation of the bucket wheel occasionally larger parts at the cutting edge between Cell wheel housing and cell wheel web are located. A cut up these parts like This is normal for cellular wheels, but is not required for this version.
Figur 6 zeigt ein Zellenrad-Dosiergerät für schwer fließende Produkte mit einem, als Zylinder ausgebildetem Vorratsgefäß 16. An diesem befestigt die Entlastungsplatte 17, das herausnehmbare Rührwerk 18, das von einem nicht dargestellten Motor angetrieben wird. Eine andere Ausführung des Zellenrades hier mit der Bezeichnung 19 mit dem Zahnradähnlich ausgebildeten Zellenradkamniern 20. In der Zeichnung ist ferner erkennbar, daß die Zellenradkammern 20 von einem Auskratzer 21 laufend sauber gehalten werden. Die Kammer ist zu diesem Zweck so ausgebildet, daß der Kratzer 21 die ganze Kammer einwandfrei bestreicht. Wichtig ist dabei, daß der in der Zeichnung angegebene Winkel 22 mindestens 10 Grad aufweist.FIG. 6 shows a cellular wheel metering device for difficult-to-flow products with a storage vessel 16 designed as a cylinder. The relief plate is attached to this 17, the removable agitator 18, which is driven by a motor, not shown will. Another version of the cell wheel here with the designation 19 with the Gear wheel-like shaped cellular wheel assemblies 20. In the drawing it can also be seen that the cellular wheel chambers 20 are kept constantly clean by a scraper 21. The chamber is designed for this purpose so that the scraper 21 covers the entire chamber perfectly coated. It is important that the angle given in the drawing 22 has at least 10 degrees.
In Figur 7 sind 3 Zellenrad-Dosiergeräte für z.B. 3 verschiedene Farben an einem Ablauftrichter von oben gesehen schematisch dargestellt. Die Dosiergeräte mit der Bezeichnung A und B sind in Arbeitsstellung, das Dosiergerät C ist dagegen um 90 ° herausgeschwenkt, damit es in diesem Zustand leichter gereinigt werden oder sogar entfernt werden kann, ohne daß noch irgendwelche Reste bei der Reinigung z.B. in den Trichter fallen.In Figure 7 there are 3 rotary feeders for e.g. 3 different colors shown schematically on a discharge funnel viewed from above. The dosing devices with the designations A and B are in the working position, the metering device C is against it Swiveled out by 90 ° so that it can be cleaned more easily in this state or can even be removed without leaving any residues after cleaning e.g. fall into the funnel.
Nicht dargestellt, aber als zweckmäßig erwiesen, hat sich eine Abhebekurve die es ermöglicht, daß beim Herausschwenken des Dosiergerätes dieses sich erst abhebt und dann wieder in die alte Ebene zurückkehrt. Diese Funktion ist von Bedeutung, um die Abdichtung zwischen dem Dosiergerät und dem Trichter nicht zu beschädigen und der zweite Effekt ist die Fixierung des Dosiergerät im ausgeschwenktem Zustand.A lift-off curve has not been shown, but has proven to be useful which makes it possible that when the dispenser is swiveled out, it only lifts off and then go back to the old plane. This function is important so as not to damage the seal between the dispenser and the funnel and the second effect is the fixation of the dispenser in the swiveled-out state.
Bei den Versuchen hat sich darüberhinaus als zweckmäßig erwiesen, soweit als möglich überall dort wo Teile mit dem Dosiergut in Berührung kommen, einen materialabweisenden Werkstoff z.B. POM zu verwenden.In the tests it has also proven to be useful as far as possible wherever parts come into contact with the dosing material, to use a material-repellent material e.g. POM.
