Abstract
Description
Die Erfindung bezieht sich auf eine Dosier- und Mischanordnung für fließfähige Feststoffe gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a metering and Mixing arrangement for flowable solids according to the Preamble of the main claim.
Eine gattungsbildende Einrichtung wird in der US-PS 29 84 521 beschrieben. Bei dieser bekannten Einrich tung werden die dosiert aus den verschiedenen Vor ratsbehältern abgezogenen Stoffe einem Zyklonmischer zugeführt, der die verschiedenen Stoffe nun ent sprechend untereinander mischt.A generic device is described in US-PS 29 84 521. In this well-known Einrich tion are dosed from the various devices removed from a cyclone mixer fed, which ent the different substances talking to each other.
Es wurde dabei als nachteilig empfunden, daß der Staubanfall im Mischer zu einer Belästigung der Um welt führen kann und der Betrieb des Mischers ener gieaufwendig ist.It was perceived as a disadvantage that the Dust accumulation in the mixer to annoy the order world and the operation of the mixer is expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Do sier- und Mischanordnung zu schaffen, bei welcher der aufwendige Mischer vermieden wird.The invention has for its object a Do creating and mixing arrangement, in which the complex mixer is avoided.
Diese der Erfindung zugrunde liegende Aufgabe wird durch die Lehre des Patentanspruches 1 gelöst.This object underlying the invention will solved by the teaching of claim 1.
Mit anderen Worten ausgedrückt: Es wird vorgeschla gen, daß über Dosierkammern aufweisende Dosierräder ein Entnehmen bestimmter Mengen aus dem zugeordneten Silo möglich ist, ohne daß der Silo aufgrund des in der Abförderleitung herrschenden Unterdrucks leerge saugt wird. Die von der Dosiereinrichtung in das je weils zugehörige Abförderrohr endgültig abgegebene Menge wird durch ein Regelventil bestimmt. Das Durchmischen dieser gewissen, gleichzeitig vor handenen Fördermengen erfolgt dann in einem Ge mischförderrohr aufgrund der dort herrschenden pneumatischen Verhältnisse. Die Produkte werden also in ihrem endgültigen Mischungsverhältnis inein ander eingeführt und dann durch die aufgrund der Pneumatik auftretende Bewegung gemischt.In other words, it is proposed gene that metering wheels having metering chambers a removal of certain quantities from the assigned Silo is possible without the silo due to the in the discharge line prevailing vacuum sucks. The from the metering device in each because associated discharge pipe finally delivered The quantity is determined by a control valve. The Mix this certain, at the same time before Existing production quantities are then carried out in one ge mixing conveyor pipe due to the prevailing there pneumatic conditions. The products are thus in their final mixing ratio other introduced and then by the due to the Pneumatic movement mixed.
Durch diese Maßnahme wird der aufwendige Mischer vermieden, und es ist als Beispiel denkbar, daß drei Silofahrzeuge Asche, Zement und Chemikalien zu einer bestimmten Baustelle bringen, dann alle drei Fahr zeuge die gleiche Zeit lang Produkte austragen, nur in unterschiedlichen Mengen und daß diese zusammen geführten unterschiedlichen Produktmengen dann auf grund ihrer Förderung gemischt werden und unmittel bar zum Verarbeitungsplatz gelangen.This measure makes the complex mixer avoided, and it is conceivable as an example that three Silo vehicles ash, cement and chemicals into one bring certain construction site, then every three driving witness delivering products for the same time, only in different quantities and that these together listed different product quantities because of their funding are mixed and immediate reach the processing station in cash.
Ein Ausführungsbeispiel der Erfindung wird nachfol gend anhand der Zeichnung erläutert.An embodiment of the invention will follow explained using the drawing.
In der Zeichnung sind drei Silos 1, 2 und 3 darge stellt, die an ihrem unteren Ende mit Dosiergehäusen ausgerüstet sind, in denen Dosierräder 4, 5 und 6 umlaufend angetrieben angeordnet sind. An die Do siergehäuse münden Absaugrohre 8, 9 und 10, die in der Zeichnung bei 19 zusammengeführt werden und in ein Gemischförderrohr 11 münden. Zwischen der Zu sammenführung 19 und dem Gemischförderrohr ist eine Treibdüsenanordnung 12 eingeschaltet, durch die in den einzelnen Absaugrohren 8, 9 und 10 ein Unter druck und in dem Gemischförderrohr 11 ein Förder druck erzeugt wird, so daß die jeweils gegenüber der Mündung dieser Absaugrohre 8, 9 und 10 in den Verteilergehäusen umlaufenden Dosierkammern 7 leer gesaugt werden und das Gut abgeführt wird.In the drawing, three silos 1 , 2 and 3 are Darge, which are equipped at their lower end with metering housings in which metering wheels 4 , 5 and 6 are arranged rotatingly driven. At the Do siergehäuse drain pipes 8 , 9 and 10 , which are merged in the drawing at 19 and open into a mixture feed pipe 11 . Between the union 19 and the mixture delivery pipe, a driving nozzle arrangement 12 is switched on, through which a vacuum is generated in the individual suction pipes 8 , 9 and 10 and a delivery pressure is generated in the mixture delivery pipe 11 , so that the respective opposite the mouth of these suction pipes 8 , 9 and 10 in the metering chambers 7 rotating around the distributor housings are sucked empty and the material is discharged.
In jede der Absaugleitungen 8, 9, 10 ist je ein Regelventil 14, 15 und 16 eingeschaltet, durch die die durch die Absaugleitungen 8, 9, 10 fließenden, d. h. abgesaugten Mengen eingeregelt werden können.In each of the suction lines 8 , 9 , 10 , a control valve 14 , 15 and 16 is switched on, by means of which the quantities flowing through the suction lines 8 , 9 , 10 , ie the amounts sucked off, can be regulated.
Durch entsprechende unterschiedliche Umlaufzahlen der Dosierräder 4, 5 und 6 werden in der Zeiteinheit unterschiedliche Mengen aus den Silos 1, 2 und 3 zur Gemischförderleitung 11 geführt. Gleichzeitig wird aber durch die Einstellung der Regelventile 14, 15 und 16 die in den Rohren fließenden Fördermengen eingeregelt, so daß dadurch ein einwandfreies Mischen im Bereich 19 zwischen den verschiedenen Produkten erfolgt.Corresponding different numbers of revolutions of the metering wheels 4 , 5 and 6 lead to different quantities from the silos 1 , 2 and 3 to the mixture delivery line 11 in the time unit. At the same time, however, the setting of the control valves 14 , 15 and 16 regulates the flow rates flowing in the tubes, so that this results in a perfect mixing in the area 19 between the different products.
Der Betrieb der vorbeschriebenen Anlage kann natür lich manuell erfolgen, es ist aber auch möglich, den Betrieb rechnergesteuert ablaufen zu lassen. Zu diesem Zweck ist ein Rechner 18 vorgesehen, der ein mal mit jedem Dosiergehäuse zugeordneten Füllstands überwachern 17 verbunden ist, zum andern mit jedem Antrieb für die Dosierräder 4, 5, 6 verbunden ist und schließlich auch die Regelung der Regelventile 14, 15 und 16 übernimmt. Durch entsprechende Ein stellung dieses Rechners ist es also möglich, den Betrieb vollautomatisch ablaufen zu lassen.The operation of the system described above can of course be done manually, but it is also possible to run the operation under computer control. For this purpose, a computer 18 is provided, which is connected to a level monitor 17 assigned to each metering housing, is connected to each drive for the metering wheels 4 , 5 , 6 and finally also takes over the control of the control valves 14 , 15 and 16 . By setting this computer accordingly, it is possible to run the operation fully automatically.
Schließlich kann die vorbeschriebene Anlage stationär oder mobil ausgebildet sein.Finally, the system described above be stationary or mobile.
