Abstract
Description
Die Erfindung betrifft eine Behandlungsvorrichtung für Schüttgut. Ferner betrifft die Erfindung eine Behandlungsanlage für Schüttgut mit mindestens einer derartigen Behandlungsvorrichtung.The invention relates to a treatment device for bulk material. Furthermore, the invention relates to a treatment plant for bulk material with at least one such treatment device.
Zur Herstellung von Schüttgutgemischen sind Wäge-und/oder Mischeinrichtungen aus dem Stand der Technik bekannt. Beispiele hierfür und Beispiele für weiteren Stand der Technik im Zusammenhang mit Schüttgutbehältern geben die
Eine solche Behandlungsvorrichtung für Schüttgut ist typischerweise Bestandteil einer Behandlungsanlage, deren Komponenten auf mehreren Ebenen übereinander angeordnet sind, zwischen denen üblicherweise eine gravimetrische Schüttgut- und/oder Additiv-Förderung stattfindet.Such a treatment device for bulk material is typically part of a treatment plant whose components are arranged on several levels one above the other, between which usually takes place a gravimetric bulk and / or additive promotion.
Es ist eine Aufgabe der vorliegenden Erfindung, eine Behandlungsvorrichtung der eingangs genannten Art derart weiterzubilden, dass eine kompaktere Behandlungsanlage resultiert.It is an object of the present invention to develop a treatment device of the type mentioned in the beginning such that a more compact treatment plant results.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Behandlungsvorrichtung mit den in Anspruch 1 angegebenen Merkmalen.This object is achieved by a treatment device with the features specified in claim 1.
Erfindungsgemäß wurde erkannt, dass in der Behandlungsvorrichtung sowohl ein Verwiegen als auch ein Durchmischen des Schüttguts stattfinden kann. Dies spart beim Einsatz einer solchen Behandlungsvorrichtung in einer Behandlungsanlage eine Komponentenebene, da typischerweise bei den bekannten Behandlungsanlagen in einer ersten, oberen Ebene zunächst ein Verwiegen stattfindet und in einer zweiten, darunter liegenden Ebene ein Vermischen der verwogenen Schüttgutanteile. Durch eine Kombination der Funktionen „Verwiegen“ und „Vermischen“ in ein und derselben Behandlungsvorrichtung lässt sich nun eine dieser beiden Ebenen einsparen. Zudem resultiert die Integration der Funktionen „Verwiegen“ und „Vermischen“ in ein und derselben Behandlungsvorrichtung in einer insgesamt kompakten Wiege/Mischeinrichtung. Es resultiert eine hinsichtlich ihrer Bauhöhe kompaktere Behandlungsanlage. Mit Hilfe der mindestens einen Gaszufuhr-Düse ist ein Vermischen von Granulatanteilen und/oder ein Vermischen von Pulveranteilen möglich. Die Behandlungsvorrichtung eignet sich insbesondere zur Behandlung von Kunststoff-Schüttgütern, die Ausgangsmaterialien beispielsweise für die Compoundherstellung sein können. Über die Mischgas-Einleitung kann zudem ein Sichteffekt herbeigeführt werden, bei dem unerwünscht kleine Schüttgutanteile abgeschieden werden können. Das Mischgas kann in Form von Mischgas-Impulsen eingeleitet werden. Die Behandlungsvorrichtung kann Bestandteil einer Behandlungsanlage sein, deren Komponenten auf mehreren Ebenen übereinander angeordnet sind, kann aber auch unabhängig zum Verwiegen und Vermischen von Schüttgut eingesetzt werden. According to the invention, it has been recognized that both weighing and mixing of the bulk material can take place in the treatment device. This saves the use of such a treatment device in a treatment plant, a component level, since typically in the known treatment plants in a first, upper level, first weighing takes place and in a second, underlying level, a mixing of the weighed bulk solids. By combining the functions "weighing" and "mixing" in one and the same treatment device, one of these two levels can now be saved. In addition, the integration of the functions "weighing" and "mixing" in one and the same treatment device results in an overall compact weighing / mixing device. This results in a more compact in terms of height treatment plant. With the help of the at least one gas supply nozzle mixing of granules and / or mixing of powder components is possible. The treatment device is particularly suitable for the treatment of plastic bulk materials, which may be starting materials, for example, for compound production. In addition, a visual effect can be brought about via the introduction of mixed gas, in which undesirable small bulk material fractions can be separated. The mixed gas can be introduced in the form of mixed gas pulses. The treatment device may be part of a treatment plant whose components are arranged on several levels one above the other, but can also be used independently for weighing and mixing of bulk material.
Eine Saugförderung nach Anspruch 2 hat sich in der Praxis als besonders geeignet herausgestellt. Alternativ ist auch eine pneumatische Druckförderung zur Förderung des Schüttguts und insbesondere verschiedener Schüttgut-Bestandteile in den Behälter möglich.A suction conveyor according to
Eine Mehrzahl von Gaszufuhr-Düsen nach Anspruch 3 hat sich für eine effiziente Durchmischung des Schüttguts als besonders geeignet herausgestellt. Die Gaszufuhr-Düsen können so zum Behälter ausgerichtet sein, dass beispielsweise ein Drallwinkel einer Mischgas-Zufuhr vorgegeben werden kann, so dass das Mischgas in den Behälter-Innenraum beispielsweise mit einer tangentialen Impulskomponente eingeleitet wird. Es kann also eine initiale Impulsrichtung einer Gaseinleitung zur Optimierung eines Mischergebnisses vorgegeben werden. Die Anzahl der Gaszufuhr-Düsen kann im Bereich zwischen zwei und zwanzig liegen. Insbesondere können vier, sechs, acht, zehn, zwölf oder fünfzehn Gaszufuhr-Düsen zum Einsatz kommen. A plurality of gas supply nozzles according to
Eine ringförmige Düsenanordnung nach Anspruch 4 hat sich zur Erzielung eines effizienten Mischergebnisses als besonders geeignet herausgestellt.An annular nozzle arrangement according to
Eine Anordnung der Düsen nach Anspruch 5 vermeidet Totvolumina, in denen keine oder eine nur wenig effektive Durchmischung stattfindet.An arrangement of the nozzle according to
Eine Schließeinheit nach Anspruch 6 ermöglicht eine automatisierte Entleerung eines verwogenen und gemischten Schüttgut-Behälterinhalts.A clamping unit according to
Eine Schließeinheit mit einem Schließkegel nach Anspruch 7 ist sicher und robust. Ein Schließkegel begünstigt zudem eine Geometrie des Behälter-Innenraums ohne störende Totvolumina.A closing unit with a closing cone according to
Leitbleche nach Anspruch 8 haben sich zur Optimierung eines Mischergebnisses als besonders geeignet herausgestellt. Die Leitbleche können, sofern ein Schließkegel eingesetzt wird, an einer Außenwand des Schließkegels angebracht sein. Die Leitbleche können austauschbar und/oder verlagerbar ausgeführt sein. Über die Leitbleche kann eine Drallbewegung des Mischgases und/oder des zu vermischenden Schüttguts erreicht werden. Guide plates according to
Die Vorteile einer Behandlungsanlage nach den Ansprüchen 9 und 10 entsprechen denen, die vorstehend unter Bezugnahme auf die Behandlungsvorrichtung bereits erläutert wurden.The advantages of a treatment plant according to
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. In dieser zeigen:An embodiment of the invention will be explained in more detail with reference to the drawing. In this show:
