- Such containers have on their underside one or more of the discharge devices.
- outlet means comprises a funnel-shaped outlet body 2, which is connected to a partially illustrated silo container body 3.
- the outlet body 2 and arranged in its interior 4 bowl insert 5 form the outlet device 1.
- the bowl insert 5 is formed as a ventilation insert, which consists of an air-permeable material, such as a metal mesh or a fabric mat.
- the bowl insert 5 is fastened to an upper edge 6 of the outlet body 2 and to a lower edge 7 of the outlet body 2 on the outlet body 2. Between the bowl insert 5 and the wall of the outlet body 2, an annular space 8 is formed, which can be acted upon with compressed air 9.
- the container 3 is filled with dusty or granular bulk material, which is filled by filling holes, not shown, in the upper region of the container 3 in this.
- the outlet body 2 narrows down to a narrower cross-section of a connecting piece 10, to which one or more delivery lines, not shown, can be connected.
- the bulk material Due to its consistency, the bulk material usually tends to clumping and bridging, by which the flowability and flowability of the bulk material is impaired when emptying the container 3.
- the clumping and bridge formation in the region of the bulk material is further intensified by the bulk material contained in the container 3 from above on the bulk material in the outlet device 1. Aggravating affects the acting on the bulk material in the container 3 upper pressure.
- the bowl insert 5 is provided. Upon exposure of the intermediate space 8 with compressed air 9 via a laterally attached to the outlet body 2 nozzle 11, the compressed air is forced through the air-permeable material of the bowl insert 5, so that a directed into the interior 4 of the outlet body 2 air flow 12 is formed.
- the air flow 12 leads to a loosening of the bulk material in the outlet device 1 and causes or maintains the trickle or flowability of the bulk material during the emptying process.
- the bowl insert 5 is not designed as an air-permeable ventilation insert, but consists of a preferably elastically deformable air-impermeable material.
- the bowl insert 5 has an upper projecting edge, with which it is attached to the upper edge 6 of the outlet body 2.
- the bowl insert 5 extends at a distance from the wall of the inner body 2, so that between the bowl insert 5 and the wall of the outlet body 2 of the gap 8 is formed.
- an annular gap 13 is formed between the bowl insert 5 and the wall of the outlet body 2.
- the compressed air passes through the gap 13 and thereby supports the emptying of the container 3.
- areas of air-permeable material may be provided, so that a combination of in the FIGS. 6 and 7 illustrated embodiments of known outlet devices results.
- a major problem of provided with a bowl insert 5 known outlet devices 1 is their cleaning.
- dead spaces form, which can become clogged with bulk material during the emptying of the container 3.
- the outlet device 1 via a in the FIGS. 6 and 7 not shown separate nozzle with a cleaning liquid to rinse.
- the outlet device 1 via a in the FIGS. 6 and 7 not shown separate nozzle with a cleaning liquid to rinse.
- the outlet device 1 via a in the FIGS. 6 and 7 not shown separate nozzle with a cleaning liquid to rinse.
- the entire outlet device 1 is divided into its individual parts after emptying the container 3, the items cleaned and then assembled the outlet device 1 again.
- a person must go through a filling opening in the interior of the container 3 and perform there the necessary disassembly, cleaning and subsequent assembly work. This is extremely complex and associated with significant risks to the executing person.
- such a cleaning process is very time consuming, so that the outlet device 1 or the entire container 3 is available only after a relatively long cleaning phase for a new bulk material intake.
- the present invention can remedy this. According to the invention it is proposed that the bowl insert 5 is not rigid and only with a considerable effort of the Outlet body 2 is releasably secured thereto, but is fastened via fastening means on the outlet body 2, which can be actuated to vary the distance between the wall of the outlet body 2 and the bowl insert 5.
- the fastening means are designed as length-adjustable cylinder 14, of which in FIG. 1 only one example is shown.
- At least two cylinders 14 are provided in the outlet device according to the invention in order to hold the bowl insert 5 securely and reliably and in a precisely defined position on the outlet body 2.
- the cylinders 14 each have two telescopically movable parts, an outer part 14 a, which is fixed to the outlet body 2, and a longitudinally displaceably guided inner part 14 b, which is fixed to the bowl insert 5.
- the bowl insert 5 is therefore not - as in the prior art - fixed with its upper edge to the upper edge 6 of the outlet body 2.
- the attachment of the bowl element 5 to the outlet body 2 is rather only by the cylinder 14.
- the upper edge 15 of the bowl insert 5 is located on the wall of the outlet body 2 at.
- a sealing element for example an annular sealing lip, between the bowl element 5 and the wall of the Outflow body 2 may be provided.
- the annular gap 13 is formed between the bowl element 5 and the wall of the outlet body 2, through which the air flow 12 flows to increase the flowability and flowability of the bulk material.
- the outlet device 1 according to the invention or the bowl insert 5 is in FIG. 1 shown in its or its operating position.
- the inner part 14b of the cylinder 14 projects beyond the outer part 14a downwards.
- the inner part 14b is simply pushed up mechanically by a person. Consequently, the bowl member 5 is raised, so that the distance between the bowl member 5 and the wall of the outlet body 2 increases (see. FIG. 5 ).
- the actuation of the cylinder 14 can be done from outside the outlet body 2; an entry into the interior of the container 3 is not required.
- the raised position of the bowl element 5 is referred to as a cleaning position. In this position, the outlet device 1 can be freed by applying compressed air and / or a cleaning liquid of fixed bulk material.
- openings 14c are provided through which a locking pin 17 (see. FIG. 5 ) to secure the cylinder 14 in the set position, so that the bowl member 5 remains in the set position, even if the cylinder 14 is no longer actuated.
- the cylinder 14 is mechanically operated.
- the use of pneumatic valves as fastening means is particularly advantageous since compressed air for other purposes (generation of the upper pressure, pressurization of the gap 8 with compressed air 9) is already present in the area of the outlet device 1 and could be used without great effort for the actuation of the fastening means ,
- the bowl insert 5 openings in which an air-permeable material 19 is inserted.
- air-permeable material 19 for example, a coarse-meshed fabric or a braid can be inserted into the openings of the bowl element 5.
- the bowl insert 5 is located both at its upper edge 15 and at its lower edge 16 on the wall of the outlet body 2.
- sealing elements 18 are provided, so that the gap 8 is sealed both upwards and downwards.
- FIG. 3 shown further embodiment of the outlet device 1 according to the invention a plurality of openings are formed in the bowl member 5, in each of which an air-permeable material 19 is inserted.
- the bowl insert 5 rests against the wall of the outlet body 2 only in the area of the upper edge 15. In the region of the lower edge 16, an annular gap 13 is formed.
- an air flow 12 thus results, on the one hand, through the air-permeable material 19 and, on the other hand, through the annular gap 13.
- the bowl member 5 is held by the cylinder 14 on the outlet body 2, that in the region of the lower edge 16, a first annular gap 13a and in the region of the upper edge 15, a second annular gap 13b between the bowl element 5 and the wall of the Outlet body 2 results.
- an air flow 12 thus results through the two annular gaps 13a, 13b.
- position of the bowl element 5 could be the only operating position of the outlet device 1. But it is also conceivable that at the in FIG. 1 shown Outlet device 1 in FIG. 1 shown position of the bowl member 5 represents a first operating position and the in FIG. 4 shown position of the bowl member 5 represents a second operating position.
- the bowl element 5 can be replaced by an actuation of the cylinder 14 from the first operating position ( FIG. 1 ) into the second operating position ( FIG. 4 ) and optionally secured there by means of a locking pin 17.
- a locking pin 17 In this way it is possible to produce different air streams 12 in the interior 4 of the outlet device 1, thereby adapting the loosening and fluidization of the bulk material to the consistency of the bulk material and / or the climatic conditions (eg temperature, air pressure, air humidity) and always to achieve the best possible flow and flowability of the bulk material.
- FIG. 5 is - as already mentioned - the outlet device 1 according to the invention or the bowl element 5 shown in the cleaning position.
- the inner part 14b of the cylinder 14 has been mechanically pushed upwards from outside the outlet body 2 and has been secured by the securing pin 17 relative to the outer part 14a of the cylinder 14.
- the distance between the bowl element 5 and the wall of the outlet body 2 is increased so much that a simple and complete cleaning of the intermediate space 8, in particular of dead spaces formed there, of remaining bulk material is possible.
- a Disassembly of the outlet device 1 and an entry of a person in the interior of the container 3 for cleaning is thus no longer necessary.

Abstract
Description
Die vorliegende Erfindung betrifft eine Auslaufeinrichtung eines Behälters für staubförmiges oder körniges Schüttgut mit einem kegelförmig nach unten sich auf einen engeren Querschnitt eines Anschlussstutzens für eine Förderleitung verengenden Auslaufkörper. In dem Auslaufkörper ist ein ringförmiger Schüsseleinsatz derart angeordnet, dass zwischen dem Schüsseleinsatz und einer Wandung des Auslaufkörpers ein mit Druckluft beaufschlagbarer umlaufender Raum ausgebildet ist. Der Schüsseleinsatz ist durch betätigbare Befestigungsmittel an dem Auslaufkörper befestigt. Durch Betätigung der Befestigungsmittel kann ein Abstand zwischen der Wandung des Auslaufkörpers und dem Schüsseleinsatz verändert werden.The present invention relates to a discharge device of a container for dusty or granular bulk material with a conically downwardly narrowing to a narrower cross section of a connecting piece for a delivery line outlet body. In the outlet body, an annular bowl insert is arranged such that between the bowl insert and a wall of the outlet body a pressurizable circulating space is formed. The bowl insert is secured to the spout body by actuatable fasteners. By actuating the fastening means, a distance between the wall of the outlet body and the bowl insert can be changed.
Derartige Auslaufeinrichtungen werden beispielsweise für stationäre Silobehälter oder für Behälter als Aufbauteil eines Fahrzeugs benutzt. Die Behälter besitzen eine oder mehrere der Auslaufeinrichtungen.Such outlet devices are used, for example, for stationary silo containers or for containers as a body part of a vehicle. The containers have one or more of Outlet facilities.
Auslaufeinrichtungen der eingangs genannten Art sind beispielsweise aus der
Bei Schüttgutbehältern, wie beispielsweise Silos mit im Bodenbereich angeordneten kegelförmigen Auslaufkörpern (Auslaufkegeln), wird das Schüttgut im unteren Bereich durch die anstehende Füllhöhe stark zusammengedrückt, wodurch es zu einer Brückenausbildung im Schüttgut kommen kann. Das darüber liegende Schüttgut wird durch die Brückenausbildung gehalten, so dass beim Entleeren des Behälters ein weiteres Auslaufen des Schüttguts verhindert wird. Aus diesem Grund müssen besondere Vorkehrungen getroffen werden, um eine etwaige Brückenbildung von vornherein zu verhindern oder, falls diese durch entsprechend lange Lagerzeiten entstanden ist, wieder aufzubrechen.In bulk containers, such as silos with arranged in the bottom area conical spouts (spouts), the bulk material is strongly compressed in the lower area by the upcoming filling height, which can lead to a bridging formation in the bulk material. The overlying bulk material is held by the bridge training, so that when emptying the container further leakage of the bulk material is prevented. For this reason, special precautions must be taken to any eventuality Bridging to prevent from the outset or, if this is caused by correspondingly long storage times to break up again.
Einwandige starre Auslaufkegel können dies nicht leisten, weshalb der kegelförmige Auslaufkörper häufig doppelwandig ausgeführt wird. Dazu wird üblicherweise ein im Inneren des Auslaufkörpers liegendes Schüsselelement als trichterförmige Auslauffläche aus luftdurchlässigem Folienmaterial ausgebildet, so dass zwischen der äußeren luftundurchlässigen Auslaufkegelwandung und dem inneren Schüsselelement eingebrachte Druckluft durch die luftdurchlässige Folie in den Schüttgutkegelinnenraum einströmen kann und dadurch eine Brückenbildung vermieden beziehungsweise wieder aufgelöst wird. Eine entsprechende Auslaufeinrichtung ist beispielsweise aus der
Allerdings darf das Schüsselelement aus Folienmaterial nicht derart angeordnet sein, dass während der druckluftunterstützten Schüttgutabfuhr eine Taschenbildung zwischen der äußeren Auslaufkegelwandung und der Innenkegelwandung begünstigt wird. Um eine reibungsarme Fließfähigkeit des Schüttgutmaterials zu gewährleisten, wird daher der innen liegende Folienmantel am oberen Rand fest eingespannt und am unteren Rand mittels Spannkonstruktionen, die in den verschiedensten Ausführungsformen bekannt sind, gehalten. Mit diesen Spannkonstruktionen sind jedoch auch Nachteile verbunden, insbesondere hinsichtlich der Reinigung der Auslaufkegel, die den Vorteil der Reibungsminimierung bei der Schüttgutentleerung teilweise wieder zunichte machen.However, the bowl element made of film material may not be arranged such that during the compressed air-supported bulk material removal a pocket formation between the outer Auslaufkegelwandung and the Innenkegelwandung is favored. To ensure a low-friction flowability of the bulk material, is Therefore, the inner film jacket firmly clamped at the top and held at the bottom by means of clamping structures, which are known in various embodiments. However, disadvantages are also associated with these clamping constructions, in particular with regard to the cleaning of the outlet cone, which partially obviates the advantage of minimizing the friction during bulk material emptying.
Bei bewegten Silobehältern, beispielsweise auf Fahrzeugen, tritt durch das Rütteln während der Fahrt eine zusätzliche Verfestigung des Schüttgutes auf, die das spätere Entleeren erschwert. Ein weiteres Problem der bekannten Auslaufeinrichtungen mit innen liegendem luftdurchlässigem Schüsselelement aus Gewebematerial ist dadurch gegeben, dass das staubförmige oder körnige Schüttgut zu einem Verschleiß des Gewebematerials führt, weshalb es notwendig ist, dieses von Zeit zu Zeit auszutauschen.In moving silo containers, for example on vehicles occurs by shaking while driving an additional solidification of the bulk material, which complicates the subsequent emptying. Another problem of the known outlet devices with inner air-permeable bowl element made of fabric material is given by the fact that the dusty or granular bulk material leads to a deterioration of the fabric material, which is why it is necessary to replace it from time to time.
Um Die Probleme der Auslaufeinrichtungen mit innen liegender luftdurchlässiger Auslauffläche aus Gewebematerial zu beheben, sind aus dem Stand der Technik Auslaufeinrichtungen bekannt, in deren kegelförmigem Auslaufkörper ein ringförmiger Schüsseleinsatz aus einem luftundurchlässigen Material derart angeordnet ist, dass zwischen dem Schüsseleinsatz und einer Wandung des Auslaufkörpers ein mit Druckluft beaufschlagbarer umlaufender Raum ausgebildet ist. Eine derartige Auslaufeinrichtung ist beispielsweise aus der
Durch Beaufschlagen des Zwischenraumes zwischen Schüsseleinsatz und der Wandung des Auslaufkörpers kann Luft aus dem Raum über den Spalt in den Schüttgutkegelraum gelangen und dadurch eine Brückenbildung vermieden beziehungsweise wieder aufgelöst werden. Durch die Ausgestaltung der Auslaufeinrichtung mit einem Spalt zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers, durch den die in den Raum eingebrachte Druckluft in Richtung des Anschlussstutzens strömt, wird eine schnelle und ungehinderte Entleerung des Behälters gewährleistet. In Abhängigkeit von der Strömungsgeschwindigkeit der Druckluft wird dabei eine dauerhafte oder auch kurzzeitige Schwingung des Schüsseleinsatzes erzeugt, die zusätzlich eine Auflockerung des Schüttgutes bewirkt. Der Schüsseleinsatz besteht aus einem federelastischen Material, vorzugsweise Metall oder Kunststoff.By applying the space between the bowl insert and the wall of the outlet body air can pass from the room through the gap in the bulk material cone space, thereby avoiding bridging or be dissolved again. Due to the design of the outlet device with a gap between the bowl insert and the wall of the outlet body through which the compressed air introduced into the room flows in the direction of the connecting piece, a quick and unhindered emptying of the container is ensured. Depending on the flow velocity of the compressed air while a permanent or short-term vibration of the bowl insert is generated, which additionally causes a loosening of the bulk material. The bowl insert consists of a resilient material, preferably metal or plastic.
Als besonders nachteilig bei den verschiedenen aus dem Stand der Technik bekannten Auslaufeinrichtungen ist es, dass sich - trotz aller Bemühungen, dies zu verhindern - Toträume zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers ausbilden, welche sich beim Entleeren des Behälters mit Schüttgut zusetzen können. Eine Reinigung dieser Toträume durch Beaufschlagung mit Druckluft oder einer Spülflüssigkeit im Anschluss an das Entleeren des Behälters ist äußerst aufwändig und in der Regel nicht zufrieden stellend, da selbst Druckluft und/oder Spülflüssigkeit die Toträume nicht vollständig von abgelagertem Schüttgut befreien können. Die Folge ist, dass die bekannten Auslaufeinrichtungen entweder nicht vollständig gesäubert werden können oder aber zur vollständigen Säuberung komplett in ihre Einzelteile zerlegt, die Einzelteile gesäubert und dann wieder zusammengesetzt werden müssen. Insbesondere für Schüttgut aus dem Bereich der Lebensmittel-, Futtermittel- oder der Chemieindustrie ist eine nur unzulängliche Reinigung der Auslaufeinrichtung nicht akzeptabel. Andererseits bedeutet eine komplette Demontage der Auslaufeinrichtung, eine Reinigung der Einzelteile und ein anschließendes Zusammensetzen der Auslaufeinrichtung einen erheblichen zeitlichen Aufwand.Particularly disadvantageous in the various known from the prior art outlet devices is that - despite all efforts to prevent this - form dead spaces between the bowl insert and the wall of the outlet body, which can be clogged with bulk material when emptying the container. A cleaning of these dead spaces by exposure to compressed air or a rinsing liquid following the emptying of the container is extremely complicated and usually unsatisfactory, since even compressed air and / or rinsing liquid can not completely rid the dead spaces of deposited bulk material. The result is that the known outlet facilities either can not be completely cleaned or completely decomposed for complete cleaning into their individual parts, the items must be cleaned and then reassembled. In particular, for bulk material from the food, feed or chemical industry is only inadequate cleaning of the outlet device is not acceptable. On the other hand, a complete disassembly of the outlet device, a cleaning of the items and a subsequent assembly of the outlet means a considerable amount of time.
Deshalb liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Auslaufeinrichtung eines Behälters für staubförmiges oder körniges Schüttgut der eingangs genannten Art dahingehend auszugestalten oder auszubilden, dass diese einerseits ein Fluidisieren und eine Auflockerung des Schüttguts beim Entleeren des Behälters über die Auslaufeinrichtung ohne Brückenbildung und Verklumpen ermöglicht, andererseits aber auch ohne großen Aufwand und vor allem vollständig und sauber zu reinigen ist.Therefore, the present invention is based on the object an outlet device of a container for dusty or granular bulk material of the type mentioned in such a form or form that this on the one hand fluidizing and loosening of the bulk material during emptying of the container on the outlet device without bridging and clumping allows, on the other hand but also without much effort and above all is completely and clean to clean.
Zur Lösung dieser Aufgabe wird ausgehend von der Auslaufeinrichtung der eingangs genannten Art vorgeschlagen, dass die Befestigungsmittel durch die Wandung des Auslaufkörpers hindurch ragen und von außerhalb des Auslaufkörpers betätigbar sind.To solve this problem is proposed starting from the outlet device of the type mentioned above, that the fastening means protrude through the wall of the outlet body and are actuated from outside the outlet body.
Der Schüsseleinsatz ist also an dem Auslaufkörper über Befestigungsmittel befestigt, die ein Abheben des Schüsseleinsatzes von der Wandung des Auslaufkörpers insbesondere zu Reinigungszwecken ermöglichen, ohne dass die gesamte Auslaufeinrichtung beziehungsweise der Auslaufkörper in seine Einzelteile zerlegt werden müsste. Auf diese Weise können selbst Toträume, die sich trotz größter Sorgfalt bei der Konstruktion der Auslaufeinrichtung zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers bilden können und die sich beim Entleeren des Behälters mit Schüttgut zusetzen können, während des Reinigungsprozesses schnell und einfach und insbesondere vollständig von Schüttgut befreit und gereinigt werden. Insofern eignen sich die erfindungsgemäßen Auslaufeinrichtungen insbesondere für Behälter zum Transport von Schüttgut aus der Lebensmittel-, Futtermittel- und/oder Chemieindustrie. Durch die vorliegende Erfindung kann der Reinigungsprozess erheblich verkürzt werden, so dass der vollständig gereinigte Behälter bereits nach kürzester Zeit wieder zur Aufnahme neuen Schüttguts bereitsteht.The bowl insert is thus attached to the outlet body via fastening means which allow lifting of the bowl insert from the wall of the outlet body in particular for cleaning purposes, without the entire outlet device or the outlet body would have to be broken down into its individual parts. In this way, even dead spaces that can form despite the utmost care in the construction of the outlet device between the bowl insert and the wall of the outlet body and can clog when emptying the container with bulk material, during the cleaning process quickly and easily and especially completely of bulk material freed and getting cleaned. In this respect, the outlet devices according to the invention are particularly suitable for containers for the transport of bulk material from the food, animal feed and / or chemical industry. By the present invention, the cleaning process can be significantly shortened, so that the completely cleaned container is ready after a very short time again for receiving new bulk material.
Die Form des in den Innenraum des Auslaufkörpers eingesetzten Schüsselelements entspricht einem konischen Ring. Sie kann aber auch als trichterförmig bezeichnet werden.The shape of the bowl element inserted into the interior of the outlet body corresponds to a conical ring. But it can also be called funnel-shaped.
Erfindungsgemäß kann auf einen Einstieg in den Behälter zum Reinigen der Auslaufeinrichtung verzichtet werden. Vielmehr kann der Abstand des Schüsseleinsatzes zu der Wandung des Auslaufkörpers durch Betätigung der Befestigungsmittel von außerhalb des Auslaufkörpers und damit ohne in den Behälter einsteigen zu müssen, verändert werden. Ebenfalls von außerhalb des Auslaufkörpers kann dann eine Druckluftleitung und/oder eine Spülflüssigkeitsleitung zur Reinigung der Auslaufeinrichtung an den Auslaufkörper angeschlossen werden.According to the invention can be dispensed with an entry into the container for cleaning the outlet device. Rather, the distance of the bowl insert to the wall of the outlet body by pressing the fastener from outside the outlet body and thus without having to get into the container to be changed. Also from outside the outlet body then a compressed air line and / or a rinsing liquid line can be connected to the outlet body for cleaning the outlet device.
Gemäß einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass durch Betätigung der Befestigungsmittel der Schüsseleinsatz mindestens zwischen einer Betriebsstellung mit einem bestimmten Abstand zwischen der Wandung des Auslaufkörpers und dem Schüsseleinsatz und einer Reinigungsstellung mit einem gegenüber der Betriebsstellung größeren Abstand verstellbar ist. Durch Vergrößern des Abstandes zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers lockert sich selbst in Toträumen komprimiertes und festgedrücktes Schüttgut und kann durch Druckluft und/oder eine Spülflüssigkeit ohne großen Aufwand aus dem Raum zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers herausgeblasen beziehungsweise herausgespült werden. Beim Einsatz einer Spülflüssigkeit ist es vorteilhaft, wenn nach dem Spülvorgang die Auslaufeinrichtung beziehungsweise der Auslaufkörper mittels Druckluft trocken geblasen wird.According to an advantageous embodiment of the invention it is proposed that by operating the fastening means of the bowl insert at least between an operating position with a certain distance between the wall of the outlet body and the bowl insert and a Cleaning position with a relation to the operating position greater distance is adjustable. By increasing the distance between the bowl insert and the wall of the outlet body loosens even in dead spaces compressed and firmly pressed bulk material and can be blown out by compressed air and / or a rinsing liquid without much effort from the space between the bowl insert and the wall of the outlet body or flushed out. When using a rinsing liquid, it is advantageous if, after the rinsing process, the outlet device or the outlet body is blown dry by means of compressed air.
Selbstverständlich ist es denkbar, dass der Schüsseleinsatz durch Betätigen der Befestigungsmittel nicht nur in der Betriebsstellung und in der Reinigungsstellung, sondern auch noch in einer oder mehreren Zwischenstellungen angeordnet werden kann. Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung wird vorgeschlagen, dass durch Betätigung der Befestigungsmittel der Schüsseleinsatz mindestens zwischen einer ersten Betriebsstellung mit einem ersten Abstand zwischen der Wandung des Auslaufkörpers und dem Schüsseleinsatz und einer zweiten Betriebsstellung mit einem gegenüber der ersten Betriebsstellung größeren zweiten Abstand verstellbar ist. Gemäß dieser Ausführungsform kann der Schüsseleinsatz zur Auflockerung und Fluidisierung des Schüttgutes beim Entleeren des Behälters an die Zusammensetzung des Schüttguts und/oder an klimatische Bedingungen (zum Beispiel Lufttemperatur, Luftfeuchtigkeit, Luftdruck) und/oder an andere äußere Einflussgrößen angepasst werden, um stets ein kontinuierliches und gleichmäßiges Abfließen des Schüttguts aus dem Auslaufkörper über den Anschlussstutzen und die Förderleitung zu gewährleisten. Insbesondere durch unterschiedliche Korngröße des Schüttgutes beziehungsweise durch unterschiedliche Luftfeuchtigkeit im Inneren des Behälters kann die Fluidität des Schüttgutes beeinträchtigt werden. Dieser Beeinträchtigung kann durch eine Variation der Rüttelbewegungen des Schüsseleinsatzes entgegengewirkt werden. Die Rüttelbewegungen lassen sich insbesondere hinsichtlich ihrer Amplitude und ihrer Frequenz variieren. Zur Variation des Schüsseleinsatzes kann der Abstand zwischen dem Schüsseleinsatz und der Wandung des Auslaufkörpers verändert werden. Alternativ oder zusätzlich kann auch die in den Raum zwischen Schüsseleinsatz und Wandung des Auslaufkörpers eingebrachte Druckluft in Stärke und Art der Beaufschlagung (kontinuierlich oder pulsierend) variiert werden.Of course, it is conceivable that the bowl insert can be arranged by pressing the fastening means not only in the operating position and in the cleaning position, but also in one or more intermediate positions. According to a preferred embodiment of the present invention, it is proposed that by operating the fastening means of the bowl insert at least between a first operating position with a first distance between the wall of the outlet body and the bowl insert and a second operating position with a relation to the first operating position larger second distance is adjustable. According to this embodiment, the bowl insert for loosening and fluidization of the bulk material during emptying of the container to the composition of the bulk material and / or to climatic Conditions (for example, air temperature, humidity, air pressure) and / or adapted to other external factors to always ensure a continuous and uniform flow of the bulk material from the outlet body via the connecting piece and the delivery line. In particular, by different grain size of the bulk material or by different humidity in the interior of the container, the fluidity of the bulk material can be affected. This impairment can be counteracted by a variation of the shaking movements of the bowl insert. The shaking movements can be varied in particular with regard to their amplitude and their frequency. To vary the bowl insert, the distance between the bowl insert and the wall of the outlet body can be changed. Alternatively or additionally, the compressed air introduced into the space between the bowl insert and the wall of the outlet body can also be varied in terms of strength and type of impingement (continuous or pulsating).
Vorteilhafterweise besteht der Schüsseleinsatz aus Metall, insbesondere aus Edelstahl oder Aluminium, oder aus einem Kunststoff.Advantageously, the bowl insert made of metal, in particular stainless steel or aluminum, or of a plastic.
Als eine weitere Lösung der Aufgabe wird ausgehend von der Auslaufeinrichtung der eingangs genannten Art vorgeschlagen, dass die Befestigungsmittel mindestens zwei längenverstellbare Zylinder aufweisen, wobei ein erstes Ende der Zylinder an dem Schüsseleinsatz befestigt ist und die Zylinder mit ihrem zweiten Ende derart an dem Auslaufkörper befestigt sind, dass die Zylinder zur Längenverstellung von außerhalb des Auslaufkörpers betätigbar sind. Die Zylinder umfassen beispielsweise mindestens zwei teleskopartig ineinander schiebbare Teile, wobei ein Teil an dem Schüsselelement und ein anderes Teil derart an der Wandung des Auslaufkörpers befestigt ist, dass der Zylinder von außen betätigt werden kann. Dazu ragt beispielsweise der an dem Schüsselelement befestigte Teil nach außen hervor, so dass er bei Bedarf nach innen gedrückt werden kann, um das Schüsselelement von der Wandung des Auslaufkörpers abzuheben.As a further solution of the problem is proposed starting from the outlet device of the type mentioned that the fastening means at least two adjustable in length Have cylinder, wherein a first end of the cylinder is fixed to the bowl insert and the cylinder are fixed with its second end to the outlet body, that the cylinder for length adjustment from outside the outlet body are actuated. The cylinders comprise, for example, at least two telescopically telescoping parts, one part being fixed to the bowl element and another part being fixed to the wall of the outlet body such that the cylinder can be actuated from the outside. For this purpose, for example, the part attached to the bowl element protrudes outwards, so that it can be pushed inwards as needed to lift the bowl element from the wall of the outlet body.
Durch zwei Zylinder kann der Schüsseleinsatz sicher und zuverlässig in einer genau definierten Position im Inneren des Auslaufkörpers relativ zu der Wandung angeordnet werden. Selbstverständlich ist es möglich und unter Umständen auch wünschenswert, den Schüsseleinsatz durch mehr als zwei Zylinder, beispielsweise drei oder vier Zylinder, an der Wandung des Auslaufkörpers zu befestigen. Ein Ende der Zylinder ragt durch die Wandung des Auslaufkörpers nach außen, so dass die Zylinder von außerhalb des Auslaufkörpers betätigt werden können. Im Inneren des Auslaufkörpers ist das andere Ende der Zylinder an dem Schüsseleinsatz befestigt.By two cylinders, the bowl insert can be safely and reliably placed in a well-defined position inside the spout body relative to the wall. Of course, it is possible and possibly also desirable to attach the bowl insert by more than two cylinders, for example three or four cylinders, to the wall of the outlet body. One end of the cylinder protrudes through the wall of the outlet body to the outside, so that the cylinder can be actuated from outside the outlet body. Inside the spout body, the other end of the cylinder is attached to the bowl insert.
Vorzugsweise sind die Zylinder mechanisch betätigbar. Die Zylinder können beispielsweise durch einen Benutzer durch einfaches Drücken auf die Zylinder beziehungsweise auf die nach außen ragenden Teile der Zylinder verlängert werden, so dass der Abstand des Schüsselelements zu der Wandung des Auslaufkörpers vergrößert wird. Durch Drücken auf die Zylinder kann eine Gegenkraft überwunden werden, die sich beispielsweise aus der Schwerkraft oder aus einer Federkraft ergibt. In der entgegengesetzten Richtung kann die Länge der Zylinder dann durch die Schwerkraft oder die Federkraft verringert werden.Preferably, the cylinders are mechanically actuated. The Cylinders can be extended, for example, by a user by simply pressing on the cylinders or on the outwardly projecting parts of the cylinders, so that the distance of the bowl member is increased to the wall of the outlet body. By pressing on the cylinder, a counterforce can be overcome, resulting for example from gravity or from a spring force. In the opposite direction, the length of the cylinders can then be reduced by gravity or spring force.
Alternativ wird vorgeschlagen, dass die Zylinder hydraulisch, pneumatisch, elektrisch oder magnetisch betätigbar sind. Bei einer hydraulischen Betätigung könnten die Befestigungsmittel als Hydraulikventile ausgebildet sein. Bei einer pneumatischen Betätigung könnten sie dementsprechend durch Pneumatikventile betätigt werden. Da in größeren Fahrzeugen wie beispielsweise Lastkraftwagen für das Bremssystem und andere Funktionen sowieso Druckluft erzeugt wird, könnte ein Teil der Druckluft zur pneumatischen Betätigung der Zylinder herangezogen werden. Bei einer elektrischen Betätigung der Zylinder könnten diese durch Elektromotoren, vorzugsweise in Verbindung mit einem geeigneten Getriebe, welches die Drehbewegung des Elektromotors in eine entsprechende Längsbewegung umsetzt, betätigt werden. Bei einer magnetischen Betätigung der Zylinder können diese durch Elektromagneten betätigt werden.Alternatively, it is proposed that the cylinders are hydraulically, pneumatically, electrically or magnetically actuated. In a hydraulic actuation, the fastening means could be designed as hydraulic valves. In a pneumatic actuation they could accordingly be operated by pneumatic valves. Since in larger vehicles such as trucks for the brake system and other functions anyway compressed air is generated, some of the compressed air could be used for pneumatic actuation of the cylinder. In an electrical actuation of the cylinder, these could be actuated by electric motors, preferably in conjunction with a suitable gear, which converts the rotational movement of the electric motor into a corresponding longitudinal movement. In a magnetic actuation of the cylinder they can be actuated by electromagnets.
Vorteilhafterweise ist die Länge der Zylinder in den verschiedenen Stellungen des Schüsseleinsatzes festlegbar. Insbesondere ist die Länge der Zylinder in der Betriebsstellung und in der Reinigungsstellung des Schüsseleinsatzes festlegbar. Dadurch wird sichergestellt, dass die Zylinder selbst dann ihre eingestellte Länge behalten und der Schüsseleinsatz selbst dann in der eingestellten Stellung verbleibt, wenn die Zylinder nicht mehr betätigt werden. Dies bedeutet beispielsweise bei einer mechanischen Betätigung, dass die ausgefahrenen Zylinder in ihrem ausgefahrenen Zustand festgelegt werden, um das Schüsselelement in der entsprechenden Stellung zu halten, selbst wenn die Zylinder nicht mehr betätigt werden. Ebenso können die Zylinder in ihrem eingefahrenen Zustand festgelegt werden, um das Schüsselelement in seiner Betriebsstellung oder in einer seiner Betriebsstellungen zu sichern.Advantageously, the length of the cylinder in the different positions of the bowl insert can be fixed. In particular, the length of the cylinder in the operating position and in the cleaning position of the bowl insert can be fixed. This will ensure that the cylinders will retain their set length and the bowl insert will remain in the set position even when the cylinders are no longer actuated. This means, for example, in a mechanical operation that the extended cylinders are set in their extended state to hold the bowl element in the appropriate position, even if the cylinders are no longer actuated. Likewise, the cylinders can be set in their retracted state to secure the bowl member in its operative position or in one of its operative positions.
Erfindungsgemäß wird vorgeschlagen, dass die Länge der Zylinder mechanisch festlegbar ist, vorzugsweise mittels eines Sicherungsstifts, wobei bei eingesetztem Sicherungsstift eine Längsverstellung des Zylinders verhindert ist.According to the invention it is proposed that the length of the cylinder is mechanically fixed, preferably by means of a locking pin, wherein when inserted locking pin longitudinal adjustment of the cylinder is prevented.

Der Behälter 3 ist mit staubförmigem oder körnigem Schüttgut befüllt, das durch nicht dargestellte Einfüllöffnungen im oberen Bereich des Behälters 3 in diesen eingefüllt wird. Ein Entleeren des Behälters erfolgt über die dargestellte Auslaufeinrichtung 1. Der Auslaufkörper 2 verengt sich nach unten auf einen engeren Querschnitt eines Anschlussstutzens 10, an den eine oder mehrere nicht dargestellte Förderleitungen angeschlossen werden können. Zum Entleeren des Behälters 3 wird dieser mit einem sogenannten Oberdruck beaufschlagt, der zum Ziel hat, das Schüttgut zu fluidisieren und aus dem Behälter 3 über den Auslaufkörper 2 und den Anschlussstutzen 10 durch die Förderleitungen zu drücken.The container 3 is filled with dusty or granular bulk material, which is filled by filling holes, not shown, in the upper region of the container 3 in this. An emptying of the container via the illustrated
Aufgrund seiner Konsistenz neigt das Schüttgut üblicherweise zu Verklumpungen und Brückenbildung, durch welche die Riesel- und Fließfähigkeit des Schüttgutes beim Entleeren des Behälters 3 beeinträchtigt wird. Die Verklumpung und Brückenbildung im Bereich des Schüttgutes wird durch das von oben auf das in der Auslaufeinrichtung 1 befindliche Schüttgut drückende restliche in dem Behälter 3 enthaltene Schüttgut noch verstärkt. Erschwerende wirkt sich auch der auf das Schüttgut in dem Behälter 3 wirkende Oberdruck aus. Um hier Abhilfe zu schaffen und die Riesel- und Fließfähigkeit des Schüttgutes beim Entleeren des Behälters 3 sicherzustellen, ist der Schüsseleinsatz 5 vorgesehen. Bei einer Beaufschlagung des Zwischenraumes 8 mit Druckluft 9 über einen seitlich an dem Auslaufkörper 2 angebrachten Stutzen 11 wird die Druckluft durch das luftdurchlässige Material des Schüsseleinsatzes 5 hindurchgedrückt, so dass sich ein in den Innenraum 4 des Auslaufkörpers 2 gerichteter Luftstrom 12 ausbildet. Der Luftstrom 12 führt zu einer Lockerung des in der Auslaufeinrichtung 1 befindlichen Schüttgutes und bewirkt bzw. erhält die Riesel- bzw. Fließfähigkeit des Schüttgutes während des Entleerungsvorganges.Due to its consistency, the bulk material usually tends to clumping and bridging, by which the flowability and flowability of the bulk material is impaired when emptying the container 3. The clumping and bridge formation in the region of the bulk material is further intensified by the bulk material contained in the container 3 from above on the bulk material in the
