The covering panel (11) and the discharge base (7) can be moved in relation to one another between an open state, in which the discharge openings (9) of the discharge base (7) and the openings (12) of the covering panel (11) overlap one another at least in part, and are preferably congruent, and a closed state, in which the discharge openings (9) of the discharge base (7) are offset axially from the openings (12) of the covering panel (11) to such an extent (s) that there is no overlap.

Description

System zur Abgabe von Schüttgut sowie Behälter mit einem solchen SchüttgutabgabesystemSystem for delivering bulk material and containers with such a bulk material delivery system
Die Erfindung geht aus von einem System zur Abgabe von Schüttgut, insbesondere von rieselfähigem Schüttgut wie z.B. Granulat, aus einem Behälter wie beispielsweise einem Silo, nach dem Oberbegriff des Anspruchs 1 sowie einem Behälter mit einem solchen Schüttgutabgabesystem gemäß Anspruch 10.The invention is based on a system for the delivery of bulk material, in particular of free-flowing bulk material, such as e.g. Granules, from a container such as a silo, according to the preamble of claim 1 and a container with such a bulk material delivery system according to claim 10.
Vorrichtungen zur dosierten Austragung von verschiedenartigem Schüttgut aus einem Speicher sind in einer Vielzahl von Ausführungsformen bekannt. Beispielsweise ist aus der Offenlegungsschrift DE 44 09 105 Al ein Behälter bekannt, bei welchem rieselfähiges Schüttgut durch eine Zellenradschleuse aus einer Entnahmeöffnung ausgetragen werden kann, indem Schüttgut in definierten Mengen in die Zellen des Rades einströmt und dann durch Drehen des Rades abgegeben wird.Devices for the metered discharge of various bulk goods from a storage are known in a variety of embodiments. For example, from the published patent application DE 44 09 105 Al a container is known in which free-flowing bulk material can be discharged through a rotary valve from a discharge opening by bulk material flows in defined amounts in the cells of the wheel and then released by turning the wheel.
Weiterhin ist es bekannt, Schleusen in Speicherbehältern durch zumindest einen, meist mehrere, gegeneinander versetzt angeordnete und/oder versetzt zueinander öffnende Schieber herzustellen. Die Speicherbehälter weisen dabei generell einen sich in Richtung auf die Schleuse verjüngenden, konischen Bereich auf, durch welchen die Größe der Schleuse und somit beispielsweise die Gewichtskräfte auf die Schieber reduziert werden.Furthermore, it is known to produce locks in storage containers by at least one, usually a plurality, offset from one another and / or staggered opening slide. The storage containers generally have a conical region tapering in the direction of the lock, by means of which the size of the lock and thus, for example, the weight forces on the slides are reduced.
Nachteilig bei den genannten Lösungen ist dabei insbesondere, dass durch die konische Form des Speichers zuströmseitig der Schleuse ein Kernfluss auftritt, durch welchen das in der Mitte des Speichers befindliche Schüttgut schneller abfließt als dasjenige an den Wänden. Dadurch verbleibt ein Teil des Schüttgutes länger im Speicherbehälter. Dies ist insbesondere bei temperaturkritischen Befüllungen eines Speicherbehälters wie z.B. PET- Granulat in einem SSP-Speicher von Nachteil, da ungleichmäßige Verweilzeiten z.B. zu ungleichmäßigen Eigenschaften des Schüttgutes führen können oder sich eine ungleichmäßige Temperaturverteilung im Schüttgut einstellen kann.A disadvantage of the solutions mentioned is in particular that due to the conical shape of the memory on the inflow side of the lock a core flow occurs, through which the bulk material located in the middle of the memory flows faster than that on the walls. As a result, a part of the bulk material remains longer in the storage container. This is especially true for temperature critical fillings of a storage container such as e.g. PET granules in a SSP memory disadvantageous as uneven residence times, e.g. can lead to uneven properties of the bulk material or can adjust an uneven temperature distribution in the bulk material.
Aufgabe der vorliegenden Erfindung ist somit, ein System zur Entnahme von Schüttgut aus einem beliebig geformten Behälter zu schaffen, durch welches es möglich ist, das Schüttgut gleichmäßig zu entnehmen, eine Schüttgutentnahme mit Kernfluss zu unterbinden und so die Verweilzeit des Schüttgutes im Behälter zu homogenisieren.Object of the present invention is thus to provide a system for removing bulk material from an arbitrarily shaped container, by which it is possible, the bulk material To remove uniformly, to prevent bulk material removal with core flow and so to homogenize the residence time of the bulk material in the container.
Die Aufgabe wird in Hinblick auf das System durch das erfindungsgemäß ausgebildete System zur Abgabe von Schüttgut aus einem Speicherbehälter gemäss Anspruch 1 und in Hinblick auf den Behälter durch einen Behälter mit einem solchen Schüttgutabgabesystem gelöst.The object is achieved with respect to the system by the inventively designed system for dispensing bulk material from a storage container according to claim 1 and with respect to the container by a container with such a bulk material delivery system.
Dabei ist vorgesehen, einen Austragsboden mit Vertiefungen mit darin ausgebildeten Austragsöffnungen mit einer abströmseitig des Austragsbodens angeordneten und von diesem beabstandeten Abdeckplatte zu kombinieren. Die Abdeckplatte weist Öffnungen auf, die im Wesentlichen in demselben Muster angeordnet sind wie die Austragsöffnungen desIt is provided to combine a discharge tray with recesses formed therein discharge openings with a downstream of the Austragsbodens and spaced from this cover plate. The cover plate has openings which are arranged substantially in the same pattern as the discharge openings of the
Austragsbodens, und ist verschieblich zu dem Austragsboden angeordnet, wodurch dieAustragsbodens, and is arranged displaceably to the discharge floor, whereby the
Öffnungen der Abdeckplatte und die Austragsöffnungen des Austragsbodens zur Abgabe von Schüttgut zur Deckung bringbar sind. Durch diese erfmdungsgemäße Maßnahme kann eine kernflussfreie Abgabe von Schüttgut erfolgen.Openings of the cover plate and the discharge openings of the discharge floor for the delivery of bulk material can be brought to cover. By this erfmdungsgemäße measure can be carried out a core flow free delivery of bulk material.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.
Vorteilhafterweise wird durch Haldenbildung des Schüttguts auf der Abdeckplatte ein indirekter Verschluss der Austragsöffnungen erzielt, wobei aufgrund des Abstands zwischen dem Austragsboden und der Abdeckplatte kein Verklemmen bzw. keine Beschädigung des Schüttgutes befürchtet werden muss.Advantageously, an indirect closure of the discharge openings is achieved by dumping the bulk material on the cover plate, wherein due to the distance between the discharge and the cover plate no jamming or damage to the bulk material must be feared.
Von Vorteil ist weiterhin, dass der Mittenabstand und die Anzahl der Öffnungen im Austragsboden und in der Abdeckplatte gleich groß sind. Ein Abstand zwischen dem Austragsboden und der Abdeckplatte ist dabei so gewählt, dass ein Fußdurchmesser der sich bildenden Halden von Schüttgut kleiner als der Mittenabstand der jeweiligen Öffnungen ist. Dadurch wird ein sicherer Verschluss ohne komplizierte Vorrichtungen ermöglicht. In einer bevorzugten Ausgestaltung der Erfindung erstreckt sich das Schüttgutabgabesystem im Wesentlichen über die gesamte Bodenfläche des Speicherraums. Dies verhindert die Bildung von Kernflüssen des Schüttguts im Speicherraum.Another advantage is that the center distance and the number of openings in the discharge tray and in the cover plate are the same size. A distance between the discharge tray and the cover plate is chosen so that a foot diameter of the forming heaps of bulk material is smaller than the center distance of the respective openings. This allows a secure closure without complicated devices. In a preferred embodiment of the invention, the bulk material delivery system extends substantially over the entire bottom surface of the storage space. This prevents the formation of core flows of the bulk material in the storage space.
Vorteilhafterweise ist das Schüttgutabgabesystem im Wesentlichen senkrecht zu einer Längsachse des Behälters angeordnet, wodurch eine einfache Austragung möglich ist.Advantageously, the bulk material delivery system is arranged substantially perpendicular to a longitudinal axis of the container, whereby a simple discharge is possible.
Die Erfindung wird im Folgenden anhand eines bevorzugten Ausführungsbeispiels in den Figuren näher erläutert. Es zeigen:The invention will be explained in more detail below with reference to a preferred embodiment in the figures. Show it:

Fig. 1 zeigt in einer stark schematisierten Schnittdarstellung einen Behälter 1, der im dargestellten Ausführungsbeispiel einen Speicherraum 2 mit einem im wesentlichen zylindrischen Querschnitt aufweist und sich zur Abgabe von in dem Behälter 1 befindlichen Schüttgut 20 in einer Abströmrichtung konisch zu einem Trichter 3 verjüngt, aus welchem durch eine Entnahmeöffnung 4 ein Teil des Schüttgutes 20 entnommen werden kann. Der Behälter 1 kann durch eine Zufuhröffnung 5 mit dem Schüttgut 20 beschickt werden. Bei herkömmlichen Behältern 1 nimmt das Schüttgut 20 den gesamten zur Verfugung stehenden Raum einschliesslich des konischen Bereichs des Trichters 3 in dem Behälter 1 ein. Dementsprechend findet bei Entnahme von Schüttgut 20 durch die zentrierte Entnahmeöffnung 4 eine ungleichmäßige Entleerung des Behälters 1 statt, da sich ein Kernfluss ausbildet, durch welchen zentral gelagertes Schüttgut 20 schneller ausgetragen wird als randnahes Schüttgut 20. Dadurch ergeben sich für randnahes Schüttgut 20 oft erheblich längere Verweilzeiten im Behälter 1 als für zentral gelagertes Schüttgut 20. Um den geschilderten Problemen entgegenwirken zu können, ist erfindungsgemäß vorgesehen, das Schüttgut 20 bereits vor dem konischen Bereich des Trichters 3 über ein geeignetes Schüttgutabgabesystem 6 zu entnehmen, so dass das im Behälter 1 vorhandene Schüttgut 20 über den gesamten Querschnitt des Behälters 1 gleichmäßig ausgetragen werden kann.Fig. 1 shows a highly schematic sectional view of a container 1, which in the illustrated embodiment has a storage space 2 with a substantially cylindrical cross-section and tapers for dispensing located in the container 1 bulk material 20 in an outflow direction conically to a hopper 3, from which a portion of the bulk material 20 can be removed through a removal opening 4. The container 1 can be fed through a feed opening 5 with the bulk material 20. In conventional containers 1, the bulk material 20 occupies all of the available space including the conical portion of the hopper 3 in the container 1. Accordingly, upon removal of bulk material 20 through the centered removal opening 4, an uneven emptying of the container 1 takes place, as a core flow forms through which centrally stored bulk material 20 is discharged faster than bulk material close to the edge 20. This results in close to bulk material 20 often considerably longer Dwell times in the container 1 as for centrally stored bulk material 20. In order to counteract the problems described, the bulk material 20 is to be removed already before the conical region of the hopper 3 via a suitable bulk material delivery system 6, so that the bulk material present in the container 1 20 can be discharged uniformly over the entire cross section of the container 1.
Das erfindungsgemäß ausgebildete Schüttgutabgabesystem 6 wird im Folgenden unter Bezugnahme auf die Fig. 2 und 3 A bis 3B in seinem Aufbau und seiner Funktionsweise näher erläutert.The inventive designed bulk material delivery system 6 is explained in more detail below with reference to FIGS. 2 and 3 A to 3B in its structure and its operation.
Wie aus Fig. 1 ersichtlich, ist in dem Schüttgutabgabesystem 6 ein Austragsboden 7 vorgesehen, welcher allgemein senkrecht zu einer Längsachse des Behälters 1 wie ein Boden in diesem angeordnet ist und den im Ausführungsbeispiel im wesentlichen zylindrischen Speicherraum 2 des Behälters 1 abschließt.As can be seen from FIG. 1, a discharge tray 7 is provided in the bulk material delivery system 6, which is arranged generally perpendicular to a longitudinal axis of the container 1 as a bottom in this and the substantially cylindrical storage space 2 of the container 1 terminates in the embodiment.
Der Austragsboden 7 weist Vertiefungen 8 auf, die jeweils mit Austragsöffnungen 9 versehen sind. Die Vertiefungen 8 sind dabei in den Austragsboden 7 beispielsweise durch Fräsen, Pressen, Stanzen oder ähnliche geeignete Verfahren eingebracht. Die Vertiefungen 8 sind konisch ausgebildet und verjüngen sich in einer Fliessrichtung des Schüttguts 20 trichterförmig.The discharge tray 7 has recesses 8, which are each provided with discharge openings 9. The recesses 8 are introduced into the discharge floor 7, for example, by milling, pressing, punching or similar suitable methods. The recesses 8 are conical and taper in a direction of flow of the bulk material 20 funnel-shaped.
Der Austragsboden 7 ist in Fig. 2 in einer stark schematisierten Aufsicht dargestellt. Die Vertiefungen 8 sind dabei dichtestmöglich zueinander angeordnet und so ausgestaltet, dass keine erhabenen Restflächen zwischen den Vertiefungen 8 übrigbleiben. Bei der vorliegenden Ausführungsform wird dies durch sechseckige Ausgestaltung der Vertiefungen 8 erreicht, wobei benachbarte Vertiefungen 8 jeweils eine gemeinsame geometrische Schnittlinie 10 aufweisen, die zur Linienmitte hin durchgebogen ist. Dies führt dazu, dass nur eine geringfügige Ablagerungsmenge von Schüttgut 20 auf den Restfiächen 10 erfolgt, so dass der vollflächige Austrag von Schüttgut 20 dadurch nicht beeinträchtigt wird. Allgemein ist zur Vermeidung von ebenen Restflächen zwischen den Vertiefungen eine polygonale Grundfläche der Vertiefungen 8 von Vorteil, die nach unten zu in einen Konus übergehen kann. Dadurch kann eine wabenförmige Anordnung der Vertiefungen erfolgen.The discharge tray 7 is shown in Fig. 2 in a highly schematic plan view. The depressions 8 are arranged as close as possible to each other and designed so that no raised residual surfaces between the recesses 8 remain. In the present embodiment, this is done by hexagonal configuration of the recesses 8 reaches, wherein adjacent recesses 8 each have a common geometric section line 10 which is bent towards the middle of the line. As a result, only a minor amount of bulk material 20 deposits on the remaining surfaces 10, so that the full-surface discharge of bulk material 20 is not impaired thereby. In general, in order to avoid even residual surfaces between the depressions, a polygonal base surface of the recesses 8 is advantageous, which can proceed downwards into a cone. This can be done a honeycomb arrangement of the wells.
Die Anzahl m der Austragsöffnungen 9 ist beliebig, liegt jedoch im vorliegenden Ausführungsbeispiel aus weiter unten näher erläuterten Gründen in einer Größenordnung von ca. 80, wobei jede der Austragsöffnungen 9 eine Öffnungsweite d\ von ca. 30 mm aufweist. Ein Mittenabstand mj zu den benachbarten Vertiefungen 8 beträgt ca. 100 mm.The number m of the discharge openings 9 is arbitrary, but in the present embodiment, for reasons explained in more detail below in a magnitude of about 80, wherein each of the discharge openings 9 has an opening width d \ of about 30 mm. A center distance mj to the adjacent recesses 8 is about 100 mm.
Dem Austragsboden 7 ist eine Abdeckplatte 11 zugepaart, welche mit einer identischen Verteilung von Öffnungen 12 versehen ist wie der Austragsboden 7 und von diesem durch einen Abstand h beabstandet ist. Die Öffnungen 12 der Abdeckplatte 11 sind jedoch nicht inThe discharge floor 7 is a Abdeckplatte 11 paired, which is provided with an identical distribution of openings 12 as the discharge floor 7 and is spaced therefrom by a distance h. However, the openings 12 of the cover plate 11 are not in

Verfahren in die Abdeckplatte 11 eingebracht und weisen einen Randabstand b zueinander auf. Die Anzahl der Öffnungen 12 beträgt dabei n2, die Öffnungsweite d2 und ein Mittenabstand m2. Dabei gilt für die Austragsöffnungen 9 und die Öffnungen 12: n\ = n2, Hi1 Method introduced into the cover plate 11 and have an edge distance b to each other. The number of openings 12 is n 2 , the opening width d 2 and a center distance m 2 . The following applies to the discharge openings 9 and the openings 12: n \ = n 2 , Hi 1

Die Abdeckplatte 11 ist verschieblich gegenüber dem Austragsboden 7 angeordnet. Die Verschieblichkeit ist in Fig. 3 A und 3B mit s bezeichnet und ist dabei so ausgelegt, dass in einem geschlossenen Zustand des Schüttgutabgabesystems 6 gemäss Fig. 3A die Öffnungen 12 der Abdeckplatte 11 keine Überschneidung mit den Austragsöffnungen 9 des Austragsbodens 7 aufweisen. Zudem ist ein Abstand der Öffnungen 12 der Abdeckplatte 11 dadurch festgelegt, dass in einem geöffneten Zustand gemäss Fig. 3B jeder Austragsöffnung 9 des Austragsbodens 7 eine Öffnung 12 der Abdeckplatte 11 zugepaart ist, so dass die im Durchmesser ähnlich dimensionierten Austragsöffnungen 9 und der Öffnungen 12 ungefähr deckungsgleich sind. Die Gründe für die Wahl der Anzahl der Vertiefungen 8 bzw. der Austragsöffnungen 9 sowie ihrer Dimensionierung liegen in der Beschaffenheit bzw. der Rieselfähigkeit des Schüttgutes 20. Wenn dieses ein Korngröße von ca. 3 bis 4 mm aufweist, ist bei einer geeigneten Dimensionierung der Austragsöffnungen 9 bzw. der Öffnungen 12 im geschlossenen Zustand des Schüttgutabgabesystems 6, wie in Fig. 3A dargestellt, zwar ein Restaustrag auf die Abdeckplatte 11 zu beobachten, bedingt durch die Korngröße findet jedoch die Bildung einer Halde 13 mit einem Fußdurchmesser k statt, die bei einem bestimmten Böschungswinkel α, dessen Größe u.a. von der Wandneigung der Vertiefungen 8, der Rieselfähigkeit des Schüttgutes 20 sowie dem vertikalen Abstand h der Abdeckplatte 11 vom Austragsboden 7 abhängt, einen stabilen Wert erreicht und somit zu einem vollständigen Verschluss der Austragsöffnungen 9 durch einen sog. indirekten Verschluss führt. Dadurch kann der Austrag des Schüttguts 20 zuverlässig durch die Verschiebung der Abdeckplatte 11 gegenüber dem Austragsboden 7 geregelt werden. Der Randabstand b der Öffnungen 12 muss somit lediglich so gewählt werden, dass der Fußdurchmesser k der gebildeten Halden 13 kleiner ist als der Randabstand b benachbarter Öffnungen 12 der Abdeckplatte 11, um den vollständigen Verschluss des Schüttgutabgabesystems 6 zu erzielen.The cover plate 11 is arranged displaceably relative to the discharge tray 7. The mobility is designated in FIG. 3 A and 3 B with s and is designed so that in a closed state of the bulk material delivery system 6 according to FIG. 3A, the openings 12 of the cover 11 have no overlap with the discharge openings 9 of the discharge floor 7. In addition, a distance between the openings 12 of the cover plate 11 is determined by the fact that in an open state according to FIG. 3B each discharge opening 9 of the discharge tray 7, an opening 12 of the cover plate 11 is paired, so that the diameter similarly sized discharge openings 9 and the openings 12th are approximately congruent. The reasons for the choice of the number of recesses 8 and the discharge openings 9 and their dimensions are in the nature or the flowability of the bulk material 20. If this has a grain size of about 3 to 4 mm, is at a suitable dimensioning of the discharge openings 9 and the openings 12 in the closed state of the bulk material delivery system 6, as shown in Fig. 3A, although to observe a residual discharge on the cover plate 11, due to the grain size, however, the formation of a heap 13 with a foot diameter k instead of at a certain slope angle α, the size of which inter alia depends on the wall inclination of the recesses 8, the flowability of the bulk material 20 and the vertical distance h of the cover plate 11 from the discharge tray 7, reaches a stable value and thus to a complete closure of the discharge openings 9 by a so-called. Indirect Closure leads. Thereby, the discharge of the bulk material 20 can be reliably controlled by the displacement of the cover plate 11 relative to the discharge tray 7. The edge distance b of the openings 12 must therefore be selected only so that the foot diameter k of the heaps 13 formed is smaller than the edge distance b of adjacent openings 12 of the cover plate 11 in order to achieve complete closure of the bulk material delivery system 6.
Die Öffnungen 12 der Abdeckplatte 11 und der Austragsöffnungen 9 des Austragsbodens 7 sind dabei im dargestellten Ausführungsbeispiel im geschlossenen Zustand des Schüttgutabgabesystems 6 jeweils um einen Betrag s gegenüber einem geöffneten Zustand verschoben, wobei s dem halben Mittenabstand (mj bzw. m2) der Austragsöffnungen 9 bzw. der Öffnungen 12 entspricht, so dass in einem geschlossenen Zustand des Schüttgutabgabesystems 6 die Öffnungen 12 der Abdeckplatte 11 zwischen den Vertiefungen 8 des Austragsbodens 7 positioniert sind. Folglich muss die Abdeckplatte 11 gegenüber dem Austragsboden 7 um den Betrag s bzw. nij/2 bzw. m2/2 verschoben werden, um zum Austrag einer definierten Menge von Schüttgut 20 die Öffnungen 12 mit den Austragsöffnungen 9 zur Deckung zu bringen.The openings 12 of the cover plate 11 and the discharge openings 9 of the discharge tray 7 are in the illustrated embodiment in the closed state of the bulk material delivery system 6 each shifted by an amount s compared to an open state, where s half the center distance (mj or m 2 ) of the discharge openings. 9 or the openings 12 corresponds, so that in a closed state of the bulk material delivery system 6, the openings 12 of the cover plate 11 are positioned between the recesses 8 of the Austragsbodens 7. Consequently, the cover plate 11 must be compared to the discharge tray 7 by the amount s or nij / 2 or m 2/2 are moved to bring to discharge a defined amount of bulk material 20, the openings 12 with the discharge openings 9 to cover.
Der Austrag des Schüttguts 20 aus dem Behälter 1 erfolgt somit im Ausführungsbeispiel zunächst über die Austragsöffnungen 9 und die Öffnungen 12 der Abdeckplatte 11 in den Trichter 3 hinein, aus welchem die ausgetragene Menge durch die Entnahmeöffnung 4 endgültig abgegeben wird. Somit wird eine gleichmäßige Verweildauer des Schüttguts 20 im Behälter 1 sichergestellt, so dass die Homogenität des Schüttguts 20 beispielsweise in Bezug auf Temperatur und resultierend auf seine Konsistenz nicht gestört wird.The discharge of the bulk material 20 from the container 1 thus takes place in the embodiment, first on the discharge openings 9 and the openings 12 of the cover 11 into the hopper 3, from which the discharged amount through the removal opening. 4 finally delivered. Thus, a uniform residence time of the bulk material 20 is ensured in the container 1, so that the homogeneity of the bulk material 20, for example, with respect to temperature and as a result of its consistency is not disturbed.
Die Form des Speicherraumes 2 ist dabei nicht auf einen zylindrischen Speicherraum 2 beschränkt, es sind auch andere Formen von Behältern 1 denkbar. Insbesondere kann das Schüttgutabgabesystem 6 auch für sich alleine stehend verwendet werden, so dass das Schüttgut 20 lediglich als Halde auf dem entsprechend dimensionierten Austragsboden 7 angeschüttet wird.The shape of the storage space 2 is not limited to a cylindrical storage space 2, there are also other forms of containers 1 conceivable. In particular, the bulk material delivery system 6 can also be used standing alone, so that the bulk material 20 is merely poured onto the correspondingly dimensioned discharge tray 7 as heap.
Es sei weiters erwähnt, dass, insbesondere bei schwer rieseiförmigen Schüttgütern, wie z.B. Flakes, es günstig sein kann, wenn über dem Austragsboden 7 ein Rührwerk 18 vorgesehen ist, wie in Fig. 1 schematisch dargestellt. Ein weiteres Rührwerk 19 kann unterhalb der Abdeckplatte 11 angeordnet sein, um das durch das Schüttgutabgabesystem 6 hindurch gelassene Schüttgut zur Entnahmeöffnung 4 hin zu bewegen. In diesem Fall kann eventuell der Trichter 3 eingespart werden.It should be further noted that, especially in heavy-gauge bulk goods, such as e.g. Flakes, it may be favorable if above the discharge tray 7, a stirrer 18 is provided, as shown schematically in Fig. 1. Another agitator 19 may be arranged below the cover plate 11 in order to move the bulk material passed through the bulk material dispensing system 6 towards the removal opening 4. In this case, the funnel 3 may possibly be saved.
Eine in den Figuren aus Gründen der Vereinfachung nicht weiter dargestellte Vorrichtung zur Ansteuerung der Abdeckplatte 11 kann dabei in beliebiger Weise beispielsweise in Form eines Elektromotors oder einer anderen geeigneten Betätigungseinheit ausgebildet sein.A device not shown in the figures for reasons of simplification for controlling the cover plate 11 may be formed in any desired manner, for example in the form of an electric motor or other suitable actuating unit.
Es sei weiters erwähnt, dass das erfmdungsgemäße System zur Abgabe von Schüttgut nicht auf die beschriebene Translationsbewegung zwischen Abdeckplatte und Austragsboden beschränkt ist. Vielmehr können die Abdeckplatte und der Austragsboden in Bezug aufeinander auch um eine Drehachse verdrehbar sein. Bei einer solchen Ausgestaltung ist allerdings zu beachten, dass die Form und Größe der Löcher sich mit zunehmendem Abstand von der Drehachse weg verändern müssen, um eine gleichmäßige Abgabe des Schüttguts zu gewährleisten.It should also be mentioned that the inventive system for delivering bulk material is not limited to the described translational movement between the cover plate and the discharge tray. Rather, the cover plate and the discharge floor with respect to each other can also be rotated about an axis of rotation. In such an embodiment, however, it should be noted that the shape and size of the holes must change away with increasing distance from the axis of rotation in order to ensure a uniform discharge of the bulk material.
Weiters ist das erfindungsgemäße System zur Abgabe von Schüttgut nicht auf eine ebene Plattenform des Austragsbodens beschränkt. Der Austragsboden und die Abdeckplatte können beispielsweise auch Kalottenform aufweisen. Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Insbesondere ist die Erfindung bei entsprechender Dimensionierung der Abmessungen für beliebiges Schüttgut 20 anwendbar. Alle Merkmale der Erfindung sind beliebig miteinander kombinierbar. Furthermore, the inventive system for the delivery of bulk material is not limited to a flat plate shape of the Austragsbodens. The Austragsboden and the cover plate may for example also have dome shape. The invention is not limited to the illustrated embodiment. In particular, the invention with appropriate dimensioning of the dimensions for any bulk material 20 is applicable. All features of the invention can be combined with one another as desired.
