Solch ein Behälter bzw. solch eine Austragshilfe ist, beispielsweise, aus der DE 196 41 827 C1 bekannt. Die untere Auslaßöffnung der bekannten Austragshilfe weist einen Ringflansch auf, der mit einem Anschlußflansch derart koppelbar ist, daß zwischen dem Ringflansch des Behälters und dem Anschlußflansch ein flexibles Zwischenstück angeordnet ist und der Rüttelkörper über den Anschlußflansch bewegbar ist. Durch Bewegung des Rüttelkörpers werden Schwingungen in den Behälter eingebracht, die eventuell auftretende Brückenbildungen des Schüttguts im Behälter zerstören oder verhindern, um das Schüttgut zwecks Entleeren des Behälters ständig im Fluß zu halten. Es hat sich jedoch herausgestellt, daß die bekannten Austragshilfen mit angetriebenen Rüttelkörpern noch stets kein ungestörtes Austragen von Schüttgut aus einem Behälter gewährleisten. Ab dem Zeitpunkt, an dem sich in einem Hohlraum innerhalb des Behälters oberhalb des Schüttguts ein Vakuum aufgebaut hat, wird ein weiterer Abfluß des Schüttguts nämlich verhindert.Such a container or such a Austragshilfe is, for example, from DE 196 41 827 C1 known. The lower outlet opening of the known discharge aid has an annular flange on, which is coupled with a connecting flange such that between the annular flange of the Container and the connecting flange, a flexible intermediate piece is arranged and the Rüttelkörper is movable over the connecting flange. By movement of the vibrating body Vibrations introduced into the container, the possibly occurring bridges of the Destroy or prevent bulk material from entering the container to empty the bulk material to empty the container Keep container constantly in the flow. However, it has been found that the known Discharge aids with driven Rüttelkörpern still no undisturbed discharge of Ensure bulk material from a container. From the time it is in a cavity within the container above the bulk material has built a vacuum is a namely, further outflow of the bulk material prevented.

Es ist zur Zeit üblich, dem Aufbauen eines Vakuums im Hohlraum oberhalb von Schüttgut in einem Behälter dadurch entgegenzuwirken, daß externe Belüflungsanschlüsse vorgesehen sind oder ein eine obere Einlaßöffnung verschließender Deckel kurzzeitig geöffnet wird. Dies steht selbstverständlich im Widerspruch zum Gebot der Reinheit, insbesondere wenn es sich bei dem Schüttgut um empfindliches oder gar gesundheitsschädliches Material handeltIt is currently common to build up a vacuum in the cavity above bulk material in counteract a container by providing external Belüflungsanschlüsse provided or an upper inlet opening occlusive lid is opened briefly. This is of course contrary to the commandment of purity, especially if it is bulk material is sensitive or even harmful material

Aufgabe der Erfindung ist es daher, den gattungsgemäßen Behälter und die gattungsgemäße Austragshilfe derart weiterzuentwickeln, daß die Nachteile des Stands der Technik überwunden werden, insbesondere ein Belüften des beim Entleeren des Behälters entstehenden evakuierten Hohlraums oberhalb des Schüttguts im Behälter ohne Kontamination der Umgebungsluft oder des Schüttguts auf einfache Weise zu realisieren.The object of the invention is therefore to provide the generic container and the generic Extend Austragshilfe so that the disadvantages of the prior art overcome be vented, in particular a venting of evacuated during emptying of the container evacuated Cavity above the bulk material in the container without contamination of the ambient air or to realize the bulk material in a simple manner.

Diese Aufgabe wird erfindungsgemäß durch eine Austragshilfe gemäß Anspruch 1 gelöst. Ferner wird diese Aufgabe durch einen Behälter für Schüttgut mit einer erfindungsgemäßen Austragshilfe gelöst, bei dem die Auslaßöffnung einen Ringflansch aufweist, der mit einem Anschlußflansch koppelbar ist, der Ringflansch des Behälters und der Anschlußflansch beweglich zueinander angeordnet sind, und der Rüttelkörper vermittels des Ringflansches über den Anschlußflansch bewegbar ist.This object is achieved by a discharge aid according to claim 1. Furthermore, this object is achieved by a container for bulk material with an inventive Discharge assistance solved, in which the outlet opening has an annular flange, which with a Coupling flange is coupled, the annular flange of the container and the connecting flange movable arranged to each other, and the Rüttelkörper by means of the annular flange over the connecting flange is movable.

Erfindungsgemäß wird zur Erleichterung einer Reinigung auch vorgeschlagen, daß der Belüftungskörper eine glatte Oberfläche aufweist.According to the invention it is also proposed to facilitate cleaning that the ventilation body has a smooth surface.

Vorgesehen sein kann auch, daß der Belüftungskörper elastisch ist.It can also be provided that the ventilation body is elastic.

Nach der Erfindung kann weiterhin vorgesehen sein, daß der Belüftungskörper mittig in dem Behälter angeordnet ist.According to the invention may further be provided that the ventilation body centered in the Container is arranged.

Eine spezielle Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß der Belüftungskörper in Form einer Stange ausgebildet ist, vorzugsweise mit einem im wesentlichen runden Querschnitt. A special embodiment of the invention is characterized in that the ventilation body is formed in the form of a rod, preferably with a substantially round cross-section.

Bevorzugt wird erfindungsgemäß dabei vorgeschlagen, daß der Anschlußflansch Teil eines ersten Anschluß-Rohrstutzens in einer Vorrichtung zum Kuppeln von zwei jeweils einen Anschluß-Rohrstutzen aufweisenden Behältern ist, jeder der Anschluß-Rohrstutzen nahe seinem dem ihn tragenden Behältnis abgewandten Ende ein bewegliches Absperrventil, insbesondere in Form einer schwenkbaren Schließklappe, aufweist, die Absperrventile aus einer Schließstellung in eine Offenstellung mittels eines nur eine der Absperrventile beaufschlagenden Schwenkantriebs überführbar sind, in dem zweiten Anschluß-Rohrstutzen das angetriebene Absperrventil gehalten ist, das von dem Antrieb beaufschlagbar ist, und der zweite Anschluß-Rohrstutzen schwimmend gelagert ist, so daß eine durch den Antrieb eingeleitete schwingende Bewegung über die beiden Anschluß-Rohrstutzen auf den Rüttelkörper und den Rüttelglied übertragbar ist.Preferably, it is proposed according to the invention that the connecting flange is part of a first connection pipe socket in a device for coupling two in each case one connection pipe socket Having tanks is, each of the outlet pipe necks near its the end bearing him carrying a movable shut-off valve, in particular in the form of a pivotable closing flap, the shut-off valves from a closed position in an open position by means of only one of the shut-off valves acting Swivel drive can be transferred, in the second connection pipe socket the driven Shut-off valve is acted upon by the drive, and the second connection pipe socket is floating, so that an introduced by the drive oscillating Movement via the two connecting pipe sockets to the vibrating body and the vibrating member is transferable.

Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß sich ein Rüttelglied durch das Schüttgut bis zumindest zur maximalen Höhe des Schüttguts im Behälter von einer Auslaßöffnung in dem Boden des Behälters in Richtung der Decke des Behälters erstreckt und zusammen mit dem Rüttelkörper in Bewegung versetzbar ist, um im Schüttgut einen internen Belüftungsdurchgang durch das Schüttgut bis zu dem Hohlraum oberhalb des Schüttguts im Behälter freizuschlagen.The invention is thus based on the surprising finding that a Rüttelglied through the bulk material to at least the maximum height of the bulk material in the container of a Outlet opening in the bottom of the container extends in the direction of the ceiling of the container and is movable together with the Rüttelkörper in motion, in bulk an internal Ventilation passage through the bulk material to the cavity above the bulk material free in the container.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel anhand einer aus einer einzigen Figur bestehenden schematischen Zeichnung im einzelnen erläutert wird. Dabei zeigt die Figur einen Behälter für Schüttgut mit einer erfindungsgemäßen Austragshilfe im Teil-Querschnitt.Further details of the invention will become apparent from the following description in which an embodiment of an existing from a single figure schematic Drawing is explained in detail. The figure shows a container for bulk material a discharge aid according to the invention in partial cross-section.

Wie der Figur zu entnehmen ist, umfaßt ein Behälter 10 eine Einlaßöffnung 11, die in seiner Decke ausgebildet und über einen Deckel 12 verschließbar ist, sowie eine Auslaßöffnung 13, die in seinem Boden ausgebildet und mittels einer ein Absperrventil darstellenden Klappe 14 verschließbar ist. In dem Behälter 10 ist ein Mischkörper 20 zum gründlichen Durchmischen des Schüttguts S und ein Rüttelkörper 30 zum Verhindern bzw. Zerstören von Schüttgutbrükken angeordnet. Ferner ist erfindungsgemäß in dem Behälter 10 eine mit dem Rüttelkörper 30 direkt sowie über eine Feder 31 indirekt verbundenes Rüttelglied in Form einer Stange 32 vorgesehen, die sich von der Auslaßöffnung 13 in Richtung der Einlaßöffnung 11 bis kurz unterhalb des Deckel 12 erstreckt. Die Stange 32 ragt dabei über die maximale Schütthöhe A in dem Behälter 10 hinaus, um in einen Hohlraum H zwischen der maximalen Schütthöhe A und der Decke des Behälters 10 bzw. dem Deckel 12 hineinzuragen.As can be seen from the figure, a container 10 comprises an inlet opening 11 which is in its Ceiling is formed and closed by a cover 12, and an outlet opening 13, formed in its bottom and by means of a shut-off valve representing a flap 14th is closable. In the container 10 is a mixing body 20 for thorough mixing of the bulk material S and a vibrating body 30 for preventing or destroying Schüttgutbrükken arranged. Further, according to the invention in the container 10 with the Rüttelkörper 30th directly and via a spring 31 indirectly connected Rüttelglied in the form of a rod 32nd provided, extending from the outlet opening 13 in the direction of the inlet opening 11 to short extends below the lid 12. The rod 32 protrudes beyond the maximum bed height A in the container 10 to enter a cavity H between the maximum bed height A and the ceiling of the container 10 and the lid 12 hineinzieuragen.

Im Anschluß wird der Betrieb der erfindungsgemäßen Austragshilfe in dem Behälter 10 der Figur beispielhaft beschrieben.Following the operation of the discharge aid according to the invention in the container 10 of Figure described by way of example.

Der Behälter 10 ist mobil und seine Klappe 14 stellt eine passive Schließklappe dar. Der mobile Behälter 10 ist über einen nicht dargestellten, stationären Behälter, insbesondere einer Produktionseinheit, wie einer Tablettenpresse, einem Mischer, einem Trockner, einem Reaktor oder dergleichen, fahrbar, um an den stationären Behälter angedockt zu werden. Der mobile Behälter 10 wird dabei derart verfahren, daß seine Auslaßöffnung 13 zu einer Einlaßöffnung der Produktionseinheit ausgerichtet ist. Die passive Klappe 14 des mobilen Behälters 10 ist dann mit einer aktiven Klappe der Produktionseinheit koppelbar. Hinsichtlich der näheren Details über die aktive und passive Schließklappe wird auf die Offenbarung der DE 43 42 962 C1 verwiesen.The container 10 is mobile and its flap 14 is a passive closing flap. The mobile Container 10 is connected via a stationary container, not shown, in particular one Production unit, such as a tablet press, a mixer, a dryer, a reactor or the like, movable to be docked to the stationary container. The mobile Container 10 is thereby moved such that its outlet opening 13 to an inlet opening the production unit is aligned. The passive flap 14 of the mobile container 10 is then coupled with an active flap of the production unit. Regarding the closer Details about the active and passive closing flap is the disclosure of DE 43 42 962 C1 directed.

Soll nun Schüttgut S aus dem mobilen Behälter 10 in die daran angekoppelte stationäre Produktionseinheit entladen werden, wird die aktive Klappe der Produktionseinheit aus Schließstellung in eine Offenstellung über einen Schwenkantrieb gezwungen, wobei die aktive Klappe die passive Klappe 14 des mobilen Behälters 10 bei ihrer Bewegung aus der in der Figur dargestellten Schließstellung in die Offenstellung mitnimmt.If now bulk material S from the mobile container 10 in the stationary production unit coupled thereto unloaded, the active flap of the production unit is from closed position forced into an open position via a rotary actuator, wherein the active flap the passive flap 14 of the mobile container 10 in its movement from that in the figure shown closed position in the open position entrains.

Gleichzeitig mit der Öffnung des Durchgangs von dem Behälter 10 zu der Produktionseinheit wird eine über die Aktivklappe mittels eines Vibrators angelegte Vibration in den Behälter 10 bzw. das Schüttgut S mittels des Rüttelkörpers 30 eingeleitet, über die passive Klappe 14, um dem Problem der Brückenbildung im Schüttgut S, das ein Entladen des Schüttguts S unmöglich machen würde, entgegenzuwirken. Simultaneously with the opening of the passage from the container 10 to the production unit is a vibration applied via the active flap by means of a vibrator in the container 10th or the bulk material S introduced by means of the Rüttelkörpers 30, via the passive flap 14 to the problem of bridging in the bulk material S, the unloading of the bulk material S impossible would counteract.

Außerdem wird simultan über die Klappen 14, den Rüttelkörper 30 sowie die Feder 31 eine Vibration auf die Stange 32 übertragen, die ihrerseits in Reaktion auf besagte Vibration im Schüttgut S einen Durchgang zur Belüftung des Hohlraumes H freischlägtIn addition, simultaneously via the flaps 14, the Rüttelkörper 30 and the spring 31 a Vibration transmitted to the rod 32, which in turn in response to said vibration in the Bulk material S a passage for ventilation of the cavity H strikes free

Besonders vorteilhaft ist es erfindungsgemäß, daß alle in Bewegung zu versetzenden Teile, nämlich die aktive Klappe mit Schwenkantrieb und Vibrator, an der Produktionseinheit angeordnet sind, so daß der mobile Behälter 10 ohne jegliche Verkabelung hin und her fahrbar ist.It is particularly advantageous according to the invention that all moving parts, namely, the active flap with rotary actuator and vibrator, arranged on the production unit are so that the mobile container 10 is mobile without any wiring back and forth.
