Abstract

If a bulk material mixture produced in a mixer (1) is intermediately stored in a downstream bunker (5), during emptying of said bunker (5) onto a conveying member (10), such as a conveyer belt, a sudden peak loading of the conveying member (10) results when the bottom opening (8) of the elongate bunker (5) is opened. Such peak loadings are to be avoided. In the new device, the bunker (5) has an elongate bottom opening (8) which extends in the longitudinal direction of the conveying member (10) and is subdivided into a plurality of closures (15) arranged in a row. Said closures (15) can be opened individually successively in a controllable sequence. By means of the new device, the bulk material, which is intermediately stored in the bunker (5), is not discharged onto the conveying member (10) over the entire length of the bottom opening (8) of the bunker (5). In contrast, the bunker (5) can be emptied successively stepwise without unnecessary delay occurring. Accordingly, the peak loading of the conveying member (10) can be decreased considerably and evened out. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Lagern und Abtransportieren von Schüttgut, insbesondere von in einem Mischer chargenweise hergestellten Gemischen, welche einen Bunker mit einer verschließbaren Bodenöffnung und eine unter der Bodenöffnung des Bunkers angeordnete Transporteinrichtung für das aus dem Bunker abgegebene Schüttgut aufweist, mit den Merkmalen des Oberbegriffs des Patentanspruchs. Eine derartige Vorrichtung ist aus der DE-C 457 668 bekannt.The invention relates to a device for storage and removal of bulk goods, especially batches in a mixer produced mixtures, which a bunker with a lockable Bottom opening and one located under the bottom opening of the bunker Has transport device for the bulk material discharged from the bunker, with the features of the preamble of the claim. A Such a device is known from DE-C 457 668.

Bei Mischanlagen ist es bekannt, in einem Mischer chargenweise bestimmte Schüttgutgemische herzustellen und diese dann bei Bedarf an Abnehmer oder Verbraucher abzugeben, d.h. beispielsweise abzusacken, in Transportfahrzeuge abzufüllen oder auch in Weiterverarbeitungsvorrichtungen oder -anlagen unmittelbar einzuleiten.In mixing plants it is known to determine batches in a mixer Produce bulk mixtures and then if necessary to buyers or Deliver consumers, i.e. to sag, for example To fill transport vehicles or also in Initiate further processing devices or systems immediately.

Da der zum Herstellen des Schüttgutgemisches vorgesehene Mischer kostspielig ist, besteht ein Interesse daran, diesen Mischer mit möglichst geringen Stillstandszeiten zu betreiben. Nach Fertigstellung eines Schüttgutgemisches ist es daher erforderlich, den Mischer ohne Zeitverzögerung zu entleeren, selbst wenn die Weitergabe des fertigen Schüttgutgemisches noch nicht unmittelbar erwünscht oder möglich ist.Since the mixer intended for producing the bulk material mixture is expensive, there is an interest in using this mixer if possible short downtimes. After completing one Bulk material mixture is therefore necessary without the mixer Empty time delay even if passing the finished one Bulk material mixture is not immediately desired or possible.

Um dieses Problem zu lösen, ist es bekannt, zwischen dem Mischer und einer für den Abtransport des Mischgutes bzw. fertigen Schüttgutgemisches zu einem Verbraucher vorgesehenen Transporteinrichtung einen Bunker vorzusehen, der zur Zwischenlagerung des Schüttgutgemisches dient und eine Bodenöffnung aufweist, durch welche das Schüttgutgemisch bei Bedarf auf die Transporteinrichtung, beispielsweise ein Transportband oder eine Förderschnecke, aufgegeben wird. To solve this problem, it is known between the mixer and one for the removal of the mix or finished bulk mix a bunker provided to a consumer provide that serves for the intermediate storage of the bulk material mixture and a Has bottom opening through which the bulk material mixture if necessary the transport device, for example a conveyor belt or a Screw conveyor, is abandoned.

Der für die Zwischenlagerung vorgesehene Bunker ist zweckmäßig unmittelbar unter dem Mischer angeordnet. Damit dieser Bunker nicht allzu hoch baut, hat er eine im Grundriß rechteckige Form, die sich an der Länge und Breite des vorzugsweise einen trommelförmigen Behälter aufweisenden Mischers orientiert, dessen Mischer mit horizontal liegender Längsachse angeordnet ist und zweckmäßig eine über die gesamte Länge des zylinderförmigen Behälters sich erstreckende Entleerungsöffnung bzw. Bodenöffnung aufweist.The bunker intended for the intermediate storage is expediently immediate arranged under the mixer. So that this bunker doesn't build too high, it has a rectangular shape in plan, varying in length and width of the mixer, preferably having a drum-shaped container oriented, the mixer arranged with a horizontal longitudinal axis is and expediently one over the entire length of the cylindrical Has container-extending drain opening or bottom opening.

Ein derartiger langgestreckter Bunker hat außerdem eine langgestreckte Bodenöffnung, weil auch das eine geringe Bauhöhe ermöglicht.Such an elongated bunker also has an elongated one Floor opening, because that also allows a low overall height.

Die bei derartigen Anlagen eingesetzten Fördereinrichtungen erstrecken sich in Längsrichtung unter der Bodenöffnung des für die Zwischenlagerung vorgesehenen Bunkers, um das zwischengelagerte Mischgut über die gesamte Länge des Bunkers auf die Fördereinrichtung aufgeben und von dieser wahlweise in die eine oder andere Richtung weiterfördern zu können.The conveyor facilities used in such systems extend in the longitudinal direction under the bottom opening of the for temporary storage provided bunkers to the temporarily stored mix over the entire Give the length of the bunker to and from the conveyor to be able to continue to promote in one direction or the other.

Es hat sich gezeigt, daß die Fördereinrichtung starken Belastungen ausgesetzt wird, wenn man die Bodenöffnung des für die Zwischenlagerung vorgesehenen Bunkers, ähnlich wie dies beim Entleeren des vorgeschalteten Mischers in den Bunker der Fall ist, auf einmal öffnet, weil dann fast schlagartig eine große Menge Schüttgut auf die Transporteinrichtung aufgeschüttet oder aufgegeben wird, was nicht nur eine starke momentane Belastung der Transporteinrichtung bedeutet, sondern auch des Antriebes der Transporteinrichung, welcher dementsprechend für hohe Spitzenbelastungen ausgelegt werden muß. It has been shown that the conveyor has heavy loads is exposed when you open the bottom of the for temporary storage provided bunkers, similar to this when emptying the upstream Mixer in the bunker opens at once, because then almost suddenly a large amount of bulk goods on the transport device is heaped up or abandoned, which is not just a strong momentary Load on the transport device means, but also on the drive the transport device, which is accordingly for high Peak loads must be designed.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Lagern und Abtransportieren von Schüttgut wie von mit einem vorgeschalteten Mischer hergestellten Schüttgutgemischen zu schaffen, welche das gemischte Schüttgut in einem Bunker stabil und dicht zwischenlagern und schonend und ohne besonders hohe und ausgeprägte Belastungsspitzen auf eine nachgeschaltete Transporteinrichtung gezielt abgeben kann, damit diese Transporteinrichtung das Mischgut je nach Bedarf und zu unterschiedlichen Abgabestellen fördert. The invention has for its object a device for storage and removal of bulk goods as well as those produced with an upstream mixer To create bulk material mixtures, which the mixed bulk material in a bunker stable and dense intermediate storage and gentle and without particularly high and pronounced Load peaks targeted at a downstream transport device can deliver so that this transport device the mix according to need and to different delivery points.

Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung der eingangs genannten Gattung gelöst, welche die kennzeichnenden Merkmale des Hauptanspruches aufweist.This object is achieved with a device of the beginning mentioned genre solved, which the characteristic features of Main claim.

Dadurch, daß die Bodenöffnung des Bunkers in aus der DE-C 457 668 bekannten Weise eine Mehrzahl von in einer Reihe hintereinander angeordneten Verschlüssen aufweist, welche in steuerbarer Folge nacheinander einzeln zu öffnen sind, kann man den Bunker derart entleeren, daß keine schlagartige Spitzenbelastung der nachgeschalteten Transporteinrichtung erfolgt, sondern diese nach und nach mit dem im Bunker befindlichen Schüttgut beladen wird und sich dementsprechend keine allzu hohen Lastspitzen ergeben, sondern die Belastung vielmehr weitgehend ausgeglichen ist. Dabei ist eine gleichmäßige und staubfreie Entleerung des Bunkers auf das nachgeschaltete Transportorgan bzw. die nachgeschaltete Transporteinrichtung auch dann möglich, wenn Schüttgüter behandelt werden, die besonders zum Stauben oder sogar zum Fließen neigen wie beispielsweise feine Kalk- oder Gipsgemische.Because the bottom opening of the bunker in a manner known from DE-C 457 668 a plurality of in a row has closures arranged one behind the other, which in controllable The bunker can be opened like this one after the other drain that no sudden peak load of the downstream Transport device takes place, but this gradually with the in Bulk goods located in the bunker are loaded and accordingly none result in excessively high load peaks, but rather the load largely is balanced. There is even and dust-free emptying of the bunker on the downstream transport organ or the downstream transport device also possible if bulk goods treated that are particularly prone to dusting or even flowing such as fine lime or gypsum mixtures.

Die vorgesehenen, sozusagen lamellenartigen Klappenverschlüsse haben gegenüber bei Entleerungsöffnungen für Bunker bekannten Schieberverschlüssen den Vorteil, daß sie auf einer vorgegebenen Entladungsfläche sozusagen schlagartig die Entladungsöffnung freigeben, während Schieberverschlüsse lange Verschiebewege und dementsprechend zu lange Entleerungszeiten erfordern.The intended, so to speak lamellar Flap closures have opposite for emptying openings for bunkers known slide closures have the advantage that they are on a predetermined Unloading the discharge area suddenly, so to speak, while slide locks have long displacements and accordingly require long emptying times.

Da die einzelnen in Reihe hintereinander geschalteten Verschlüsse der Bodenöffnung des Bunkers gesteuert geöffnet werden können, ist es erfindungsgemäß möglich, die einzelnen Verschlüsse der Bodenöffnung in einer der Transportrichtung des nachgeschalteten Transportorgans entsprechenden Folge zu öffnen, beispielsweise indem der in Transportrichtung am weitesten hinten liegende Verschluß zuerst geöffnet wird und die anschließenden Verschlüsse sich in einer einstellbaren Sequenz nacheinander öffnen. Es ist jedoch auch eine Steuerung der Öffnungsfolge in umgekehrter Richtung denkbar. Since the individual closures of the Bottom opening of the bunker can be opened controlled, it is possible according to the invention, the individual closures of the bottom opening in one of the transport direction of the downstream transport member open the corresponding sequence, for example by Direction of transport furthest back first opened is and the subsequent closures turn into an adjustable Open sequence one after the other. However, it is also a control of the Opening sequence in the opposite direction is conceivable.

Der Bunker ist zumindest im unteren Bereich und im rechtwinklig zur seiner Längserstreckung verlaufenden Querschnitt trichterförmig ausgebildet, um ein Nachrutschen des in ihm befindlichen Schüttgutes zur Entleerungsöffnung zu gewährleisten. Zusätzlich können am Bunker wie auf seiner Außenseite Rütteleinrichtungen vorgesehen sein, die insbesondere dann zweckmäßig sind, wenn schwer zu transportierendes und zur Brückenbildung neigendes Schüttgut verarbeitet wird. Außerdem ist es zweckmäßig, zwischen den in Reihe hintereinander angeordneten, im Grundriß rechteckigen oder vorzugsweise quadratischen Entleerungsöffnungen keilförmige Zwischenstücke oder Reiter anzubringen, welche das im Bunker darüber befindliche Schüttgut in Richtung der einzelnen Verschlüsse bzw. der von diesen gebildeten Auslaßöffnungen zu lenken und zu leiten.The bunker is at least in the lower area and in the cross section perpendicular to its longitudinal extent funnel-shaped to prevent the slipping in it To ensure bulk goods to the emptying opening. In addition, on Bunkers such as vibrators can be provided on its outside are particularly useful when difficult to transport and bulk material that tends to form bridges is processed. Besides, it is expedient, between the one behind the other, in plan rectangular or preferably square discharge openings to attach wedge-shaped spacers or riders, which in the bunker bulk goods located above in the direction of the individual closures or to direct and guide the outlet openings formed by these.

Unter einem Mischer (1) mit einem trommelförmigen, liegend angeordneten zylindrischen Mischbehälter (2), in welchem ein um eine horizontale Achse von einem Motor (3) drehbares Mischwerk (4) angeordnet ist, befindet sich ein langgestreckter und im Querschnitt trichterförmiger Bunker (5), in welchen das im Mischer (1) erzeugte Schüttgutgemisch schlagartig entleert werden kann, wenn sich über die gesamte Länge des Mischbehälters erstreckende, eine Bodenöffnung (6) freigebende Klappen (7) des Mischbehälters (2) geöffnet werden, wie in Fig. 2 angedeutet ist. Under a mixer (1) with a drum-shaped, lying cylindrical mixing container (2), in which a around a horizontal axis is arranged by a motor (3) rotatable mixer (4) an elongated and funnel-shaped bunker (5), in which the bulk material mixture generated in the mixer (1) suddenly empties can be if extending the entire length of the mixing tank extending, a bottom opening (6) releasing flaps (7) of the Mixing container (2) can be opened, as indicated in Fig. 2.

Der Bunker (5) ist mit einer langgestreckten Bodenöffnung (8) versehen, die sich über einer Transport- und Abfülleinrichtung (9) befindet. Diese Transport- und Abfülleinrichtung (9) enthält gekapselt ein Förderband (10), das von einem Motor (11) reversibel anzutreiben ist, so daß es das aus dem Bunker (5) durch die Bodenöffnung (8) abgegebene Schüttgut wahlweise zu einem Abfülltrichter (12) am einen Ende der Einrichtung (9) oder einem Abführstutzen (13) am anderen Ende dieser Einrichtung fördern kann, von wo das Schüttgut entweder zum Weitertransport gepackt oder abgefüllt wird oder unmittelbar zu einer Weiterverarbeitung gelangt.The bunker (5) is provided with an elongated bottom opening (8), which is located above a transport and filling device (9). This Transport and filling device (9) contains an encapsulated conveyor belt (10) which is reversibly driven by a motor (11), so that it Bulk material discharged from the bunker (5) through the bottom opening (8) optionally to a filling funnel (12) at one end of the device (9) or promote a discharge pipe (13) at the other end of this facility from where the bulk goods can either be packed for onward transport or is filled or immediately processed.

Auf der Außenseite des Bunkers (5) sind Rüttler (14) angeordnet, die vorgesehen sind, um eventuell sich im Bunker (5) bildende Brücken des Schüttgutes aufzulösen.Vibrators (14) are arranged on the outside of the bunker (5) are provided in order to possibly form bridges of the bunker (5) To dissolve bulk goods.

Die Bodenöffnung (8) des Bunkers (5) ist in eine Anzahl von einzeln zu betätigenden Verschlüssen (15) unterteilt, und zwar beim dargestellten Ausführungsbeispiel in insgesamt sechs Verschlüsse (15), von denen jeder mit einem eigenen Antrieb (16) versehen ist. Diese Antriebe (16) sind einzeln und in gesteuerter Folge bzw. Sequenz zu betätigen, so daß das im Bunker (5) befindliche Schüttgut nicht auf einmal, sondern sozusagen stufenweise nacheinander auf das Förderband (10) aufgegeben werden kann. Die Verschlüsse (15) bzw. deren Antriebe (16) lassen sich entsprechend der Förderrichtung des Förderbandes (10) nacheinander derart öffnen, daß, wenn das Förderband (10) (in Fig. 1 betrachtet) nach rechts fördert, zunächst der am weitesten rechts liegende Verschluß (15) geöffnet wird und die anderen Verschlüsse nacheinander mit einer gewissen zeitlichen Verzögerung geöffnet werden, damit das im Bunker (5) befindliche Schüttgut zwar kontinuierlich ausläuft, jedoch nicht schlagartig über die gesamte Länge des Bunkers (5) bzw. der Entleerungsöffnung (8) desselben auf das Förderband (10) aufgeschüttet wird, wodurch dieses eine zu hohe schlagartige Belastung erfahren könnte.The bottom opening (8) of the bunker (5) is closed in a number of individually actuating closures (15) divided, in the illustrated Embodiment in a total of six closures (15), each of which is provided with its own drive (16). These drives (16) are to be operated individually and in a controlled sequence or sequence so that the Bulk material (5) located not in one go, but in a manner of speaking can be gradually fed onto the conveyor belt (10) one after the other. The closures (15) and their drives (16) can be according to the Open the conveying direction of the conveyor belt (10) one after the other such that when the conveyor belt (10) (viewed in Fig. 1) conveys to the right, initially the rightmost shutter (15) is opened and the other closures one after the other with a certain time delay be opened so that the bulk material located in the bunker (5) runs out continuously, but not suddenly over the entire length of the bunker (5) or the emptying opening (8) of the same on the Conveyor belt (10) is heaped up, causing this to be too high could experience sudden stress.

In Fig. 3 und 4 ist einer der Verschlüsse (15) der Bodenöffnung (8) des Bunkers (5) in teilweise geschnittener Draufsicht und Seitenansicht dargestellt. Der in Fig. 1 gezeigte Bunker (5) hat insgesamt sechs derartiger Verschlüsse (15). 3 and 4 is one of the closures (15) of the bottom opening (8) of the Bunkers (5) in a partially cut top view and side view shown. The bunker (5) shown in Fig. 1 has a total of six such closures (15).

Jeder Verschluß (15) hat einen im Grundriß etwa quadratischen Rahmen (17), der mit umlaufenden Flanschen (18) an der Unterseite des Bunkers (5) befestigt werden kann. Die quadratische Öffnung (19) dieses Rahmens (17) ist von senkrecht verlaufenden Seitenwänden (20) aus abriebfestem Material wie Kunststoff gebildet, das eine glatte Oberfläche aufweist.Each closure (15) has an approximately square frame (17) in plan, the one with circumferential flanges (18) on the underside of the bunker (5) can be attached. The square opening (19) of this frame (17) is of vertical side walls (20) made of abrasion-resistant material formed like plastic that has a smooth surface.

An der Unterseite der Öffnung (19) sind insgesamt drei Verschlußklappen (21, 22 und 23) vorgesehen, die jeweils um eine horizontale Achse (24) um etwa 90° verschwenkbar sind, so daß sie um etwa 90° zwischen einer horizontalen Schließstellung, in der sie in Fig. 3 und 4 gezeigt sind, und einer senkrechten Öffnungsposition verschwenkt werden können. In der Schließposition überlappen die Verschlußklappen (21 bis 23) einander und enthalten hier nutförmige Ausnehmungen (25), so daß die einander gegenüberliegenden nutförmigen Ausnehmungen der einzelnen Verschlußklappen krallenartig oder labyrinthartig ineinander greifen können, wie Fig. 4 zeigt, was für eine gute Abdichtung notwendig ist.There are a total of three flaps on the underside of the opening (19) (21, 22 and 23) are provided, each around a horizontal axis (24) are pivotable about 90 °, so that they can be about 90 ° between one horizontal closed position, in which they are shown in Figs. 3 and 4, and a vertical opening position can be pivoted. In the In the closed position, the flaps (21 to 23) overlap one another and contain groove-shaped recesses (25) here, so that the one another opposite groove-shaped recesses of the individual flaps can interlock like a claw or a labyrinth like in FIG. 4 shows what is necessary for a good seal.

Während die Verschlußklappen (21 und 23) sich in der Schließposition mit ihren Längsseiten unter die entsprechende Seitenwand (20) des Rahmens (17) dichtend legen können, sind alle Verschlußklappen (21 bis 23) mit ihren Stirnenden passend an der entsprechenden Seitenwand der Öffnung (19) angeordnet, so daß hier nur eine sehr geringe Toleranz vorhanden ist und dementsprechend auch an den Stirnwänden der Verschlußklappen kein Schüttgut auslecken kann, wenn sich die Verschlußklappen in ihrer Schließposition befinden.While the flaps (21 and 23) are in the closed position their long sides under the corresponding side wall (20) of the frame (17) all sealing flaps (21 to 23) with their Front ends fitting on the corresponding side wall of the opening (19) arranged so that there is only a very small tolerance and accordingly, no on the end walls of the flaps Bulk can leak if the flaps are in their Closed position.

Jede Verschlußklappe (21 bis 23) ist an ihren beiden Stirnenden jeweils mit einem Halter (26) versehen, an welchem sich ein Lagerzapfen (27) befindet, der in einer auf der Außenseite des Rahmens (17) befestigten Lagerplatte (28) drehbar gelagert ist. Auf dem äußeren Ende jedes Lagerzapfens (27) ist ein Hebel (29) befestigt, wobei die äußeren Enden der drei Hebel (29) mittels Zapfen (30) gelenkig an einer Stellstange (31) befestigt sind, um alle Verschlußklappen (21 bis 23) gleichzeitig betätigen zu können. Each flap (21 to 23) is at its two ends provided with a holder (26) on which a bearing journal (27) is located in one on the outside of the frame (17) Bearing plate (28) is rotatably mounted. On the outer end of each Bearing pin (27) a lever (29) is attached, the outer ends the three levers (29) are articulated on a control rod (31) by means of pins (30) are attached to all flaps (21 to 23) at the same time to be able to operate.

Zum Verstellen der Verschlußklappen (21 bis 23) ist der Antrieb (16) vorgesehen, der beim dargestellten Ausführungsbeispiel als Antriebselement einen pneumatischen Zylinder (32) aufweist, dessen Kolben über eine Steuerung (33) reversibel verstellt werden kann. Die Kolbenstange (34) wirkt über eine Zahnstange auf ein Zahnrad (35), das auf einer Verlängerung (36) des einen Gelenkzapfens der mittleren Verschlußklappe (22) angeordnet ist. Somit werden Verschiebebewegungen der Kolbenstange (34) in Drehbewegungen der Gelenkzapfen (27) der mittleren Verschlußklappe (22) umgesetzt, um diese aus der horizontalen Schließposition in die vertikale Öffnungsposition und umgekehrt zu verstellen. Über die Stange (31) und die Hebel (29) werden die beiden anderen Verschlußklappen (21 und 23) mitgenommen, so daß sämtliche Verschlußklappen gleichzeitig verstellt werden, wenn der pneumatische Zylinder (32) des Antriebes (16) betätigt wird.The actuator (16) is used to adjust the flaps (21 to 23) provided that in the illustrated embodiment as a drive element has a pneumatic cylinder (32), the piston of which via a Control (33) can be reversibly adjusted. The piston rod (34) acts via a rack on a gear (35) which is on a Extension (36) of one pivot pin of the middle closure flap (22) is arranged. Thus, displacement movements of the piston rod (34) in rotary movements of the hinge pin (27) of the middle closure flap (22) implemented to move them from the horizontal closed position into the vertical opening position and vice versa. Over the bar (31) and the lever (29) are the other two flaps (21 and 23) taken with it, so that all flaps are adjusted at the same time are actuated when the pneumatic cylinder (32) of the drive (16) is actuated becomes.

Zwischen den einzelnen Verschlüssen (15) befinden sich im Bunker (5) sattelartige Querstege (37), welche verhindern, daß sich zwischen den Verschlüssen (15) im Bunker (5) Schüttgut absetzen kann. Diese sattelartigen Querstege (37) bewirken vielmehr, daß das im Bunker (5) befindliche Schüttgut stets in Richtung zu einem der Verschlüsse (15) rieselt oder strömt und durch die entsprechende Öffnung (19) den Bunker (5) verlassen kann. Brückenbildungen können, wie bereits gesagt, durch gegebenenfalls zusätzlich vorgesehene Rütteleinrichtungen (14) außerdem verhindert werden.The bunker (5) is located between the individual closures (15). saddle-like crosspieces (37), which prevent that between the Closures (15) in the bunker (5) can deposit bulk goods. This saddle-like crosspieces (37) rather cause that in the bunker (5) bulk goods in the direction of one of the closures (15) trickles or flows and through the corresponding opening (19) the bunker (5) can leave. As already mentioned, bridging can be achieved by optionally additionally provided vibrating devices (14) be prevented.
