Description
Die Erfindung bezieht sich auf ein Verfahren zur rückstandslosen Entleerung von pulverförmigem Schüttgut aus einem Behälter, welches während der Entleerung einer Vibration ausgeseht wird. Sie bezieht sich weiter auf eine Pulveraustragsvorrichtung zur Durchführung des Verfahrens.The invention relates to a method for residue-free Emptying powdery bulk material from a container, which is seen during the emptying of a vibration. It also relates to a powder discharge device to carry out the procedure.
Beim Entleeren von pulverförmigem Schüttgut aus einem Behälter verbleiben oftmals Rückstände des Schüttguts im Behälter. Dies geschieht beispielsweise durch Anhaften von Schüttgut an den Innenwänden des Behälters sowie durch Brückenbildung zwischen Partikeln des pulverförmigen Schüttguts, die zum Verklumpen des Schüttguts führt.When emptying powdery bulk material from a container residues of the bulk goods often remain in the container. This happens, for example, by adhering to bulk material the inner walls of the container and by bridging between Particles of the powdery bulk material that cause clumping of the bulk goods.
Je nach Art des Schüttguts kann es jedoch erforderlich sein, das Schüttgut rückstandslos aus dem Behälter zu entleeren. Dies ist beispielsweise bei toxischem, radioaktivem oder besonders wertvollem Schüttgut der Fall. Zur Verringerung sich bildender Rückstände des Schüttguts an den Behälterwänden wird üblicherweise der Behälter und damit auch das Schüttgut während des Entleerens einer Vibration ausgesetzt. Statt dessen kann an Behälterwänden haftendes pulverförmiges Schüttgut wahrend des Ablaßvorgangs durch Klopfen gelöst werden. Durch keine dieser Maßnahmen wird jedoch eine vollständig rückstandslose Entleerung von pulverförmigem Schüttgut aus einem Behälter erreicht. Zusätzliche Maßnahmen, die die rückstandslose Entleerung des Schüttguts aus einem Behälter erleichtern, wie zum Beispiel die Verwendung sehr schlanker, konisch ausgebildeter Behälter, die Ausbildung der Behälterinnenwände mit einer Oberflächengüte oder der Einsatz eines Rührwerks, sind sehr aufwendig in der Herstellung und damit sehr kostenaufwendig. Depending on the type of bulk material, it may be necessary empty the bulk material from the container without leaving any residue. This is for example with toxic, radioactive or special valuable bulk goods. To reduce yourself forming residues of the bulk material on the container walls usually the container and thus the bulk material exposed to vibration during emptying. Instead Powdery bulk material adhering to container walls be knocked off during the draining process. By however, none of these measures will be completely residue-free Emptying powdery bulk material from a Container reached. Additional measures that the residue-free Facilitate emptying the bulk material from a container, such as using very slim, conical trained container, the formation of the container inner walls with a surface quality or the use of an agitator, are very complex to manufacture and therefore very expensive.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren anzugeben, das mit einfachen Mitteln eine und kostengünstig die rückstandslose Entleerung von pulverförmigem Schüttgut aus einem Behälter gewährleistet. Dies soll mit einer besonders geeigneten Vorrichtung erreicht werden.The invention is therefore based on the object of a method specify that with simple means one and inexpensive the residue-free emptying of powdery bulk goods guaranteed from a container. This is supposed to be with a special suitable device can be achieved.
Bezüglich des Verfahrens der obengenannten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das Schüttgut vor oder bei Einsetzen der Vibration durch einen Anstoß an den Behälter von dessen Behälterwand gelöst wirdRegarding the procedure of the above type is this task according to the invention solved in that the bulk material before or when vibration starts by pushing the Container is released from the container wall
Die Erfindung geht von der Überlegung aus, daß das Schüttgut durch den Anstoß an den Behälter von dessen Behälterwand gelöst wird, und daß die Partikel des so gelösten Schüttguts durch die Vibration in Schwebe gehalten werden. Ein Wiederanhaften von Partikeln des Schüttguts an der Behälterwand ist somit vermieden, und die rückstandslose Entleerung des Behälters ist gewährleistet. Somit tritt bei der Kombination des Anstoßvorgangs mit der Vibration ein synergetischer Effekt auf.The invention is based on the consideration that the bulk material detached from the container wall by the impact on the container and that the particles of the bulk solute so dissolved are kept in suspension by the vibration. A reattachment of particles of the bulk material on the container wall thus avoided, and the residue-free emptying of the container is guaranteed. Thus, when combining the Initiation process with the vibration a synergetic effect on.
Die Kombination der Vibration mit dem Anstoßvorgang kann übergangslos oder nicht übergangslos sein. Eine nicht übergangslose Kombination von Vibration und Anstoßvorgang umfaßt eine Pause zwischen dem Ende des Anstoßvorgangs und dem Beginn der Vibration. Bei einer übergangslosen Kombination von Vibration und Anstoßvorgang beginnt die Vibration unmittelbar nach oder bereits vor dem Ende des Anstoßvorgangs. Um das ins Fließen gekommene pulverförmige Schüttgut in Bewegung zu halten, erweist es sich daher als vorteilhaft, die Vibration mit dem Anstoßvorgang übergangslos zu kombinieren.The combination of vibration with the kick-off process can to be seamless or not seamless. Not a seamless one Combination of vibration and nudging process includes a pause between the end of the kickoff and the start the vibration. With a seamless combination of Vibration and initiation process starts the vibration immediately after or before the end of the kick-off process. To do that To keep flowing powdery bulk goods moving it therefore proves to be advantageous to use the vibration to seamlessly combine the kick-off process.
Bezüglich einer Vorrichtung zur Durchführung dieses Verfahrens wird die Aufgabe erfindungsgemäß gelöst durch eine Pulveraustragsvorrichtung, die einen Stößel und ein gemeinsam mit diesem an einer beweglich gelagerten Haltevorrichtung angeordnetes Vibrationselement umfaßt. Regarding an apparatus for performing this method the object is achieved according to the invention by a powder discharge device, one pestle and one together with this arranged on a movably mounted holding device Vibration element includes.
Zu Beginn eines Entleerungsvorgangs wird der Stößel an der Haltevorrichtung auf einen das pulverförmige Schüttgut tragenden Behälter zu bewegt. Beim Anstoß des Stößels an die Behälterwand wird der Impuls des Stößels auf den Behälter und damit auf das Schüttgut übertragen. Dadurch erfolgt eine Loslösung von an der Behälterinnenwand anhaftendem Schüttgut. Nach dem Anstoß des Stößels an die Behälterwand verbleibt der Stößel mit der Behälterwand in Kontakt, und die durch das mit dem Stößel verbundene Vibrationselement generierte Vibrationsbewegung wird durch den Stößel auf den Behälter und somit auf das gelöste Schüttgut übertragen. Somit werden während des Entleerungsvorgangs die von der Behälterwand gelösten Partikel des pulverförmigen Schüttguts in Schwebe gehalten, wodurch ein Anhaften von Schüttgut an der Behälterwand und somit die Bildung von Rückständen vermieden ist.At the start of an emptying process, the plunger on the Holding device on a powdery bulk material Container moved too. When the plunger hits the container wall the impulse of the pestle on the container and thus transferred to the bulk material. This results in detachment of bulk material adhering to the inner wall of the container. After the plunger hits the container wall, the remains Tappet in contact with the container wall, and through the vibration element connected to the plunger generated vibration movement is through the pestle on the container and thus transferred to the loosened bulk material. Thus, during of the emptying process the detached from the container wall Particles of the powdery bulk material are suspended, causing bulk material to adhere to the container wall and thus the formation of residues is avoided.
Die Pulveraustragsvorrichtung kann sowohl hängend als auch stehend angeordnet sein.The powder discharge device can be both hanging and be arranged standing.
In vorteilhafter Ausgestaltung weist die Pulveraustragsvorrichtung einen mit der Haltevorrichtung verbundenen Bewegungsgenerator auf, der eine definierte und kontrollierte Bewegung der Anordnung während des Anstoßvorgangs und während des Vibrationsvorgangs gewährleistet.In an advantageous embodiment, the powder discharge device a motion generator connected to the holding device on which is a defined and controlled movement the arrangement during the kick-off process and during guaranteed the vibration process.
Der Bewegungsgenerator kann nach verschiedenen Prinzipien ausgebildet sein, beispielsweise pneumatisch, mechanisch oder hydraulisch. Zweckmäßigerweise ist als Bewegungsgenerator jedoch ein Hubmagnet vorgesehen. Der Hubmagnet beschleunigt die beweglich aufgehängte Haltevorrichtung mit dem Stößel und dem Vibrationselement, läßt den Stößel gegen den Behälter schlagen und preßt anschließend den Stößel gegen den Behälter.The motion generator can work according to different principles be designed, for example pneumatically, mechanically or hydraulic. However, it is useful as a motion generator a solenoid is provided. The solenoid accelerates the movably suspended holding device with the plunger and Vibrating element, leaves the plunger against the container hit and then press the plunger against the Container.
