Abstract
Description
Die 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, wobei die Auslaufeinrichtung bzw. der Auslaufkörper reversibel mit dem Behälter verbunden ist, und in dem Auslaufkörper ein Schüsseleinsatz angeordnet ist, der einen oberen auskragenden Rand aufweist, der im Bereich der Kontaktfläche zwischen Behälter und Auslaufkörper gehalten wird, wobei an einem unteren Rand eine kreisförmige untere Öffnung an der dem auskragendem Rand entgegengesetzten Seite des Schüsseleinsatzes befindlich ist, wobei ein umlaufender Spalt zur Wandung des Auslauflcörpers besteht, und der Schüsseleinsatz einen an der Öffnung angeformten Stutzen aufweist, der in den Auslauf hineinragt, wobei im Bereich des Stutzens zwischen der Wandung des Schüsseleinsatzes und der Wandung des Auslaufkörpers eine Ringdichtung angeordnet ist, wie sie beispielsweise aus der DE 92 06 087 bekannt ist.The invention relates to an outlet device of a container for dusty or Grainy bulk material with a cone shaped down to a narrower one Cross section of a connecting piece for a conveying line narrowing outlet body, wherein the outlet device and the outlet body reversible with the container is connected, and disposed in the outlet body a bowl insert is having an upper protruding edge, which is in the range of Contact surface between the container and the outlet body is held, with a lower edge of a circular lower opening at the cantilever Edge opposite side of the bowl insert is located, wherein a circumferential gap exists to the wall of the Auslauflcorp, and the Bowl insert has an integrally formed on the opening neck, which in the Protruding outlet, wherein in the region of the connecting piece between the wall of the Bowl insert and the wall of the outlet body a ring seal is arranged, as is known for example from DE 92 06 087.
Bei Schüttgutbehältern, wie beispielsweise hohen Silos mit im Bodenbereich angeordneten Auslaufkegeln, wird das Schüttgut im unteren Bereich durch die anstehende Füllhöhe stark zusammengedrückt, wodurch es zu einer Brückenausbildung im Schüttgut kommen kann. Das darüberliegende Schüttgut wird durch die Brückenausbildung gehalten, so daß ein weiteres Auslaufen des Schüttguts verhindert wird. Aus diesem Grund müssen besondere Vorkehrungen getroffen werden, um eine etwaige Brückenbildung von vornherein beim Schüttgutauslauf zu verhindern oder, falls diese durch entsprechend lange Lagerzeiten entstanden ist, wieder aufzubrechen. Einwandige starre Auslaufkegel können dies nicht leisten, weshalb der kegelförmige Auslauf doppelwandig ausgeführt wird. Dazu wird üblicherweise die innenliegende trichterförmige Auslauffläche aus luftdurchlässigem Folienmaterial ausgebildet, so daß zwischen der äußeren luftundurchlässigen Kegelwandung und der Innenkegelwandung eingegebene Druckluft in den Schüttgutkegelraum einströmen kann und hierdurch eine Brückenbildung vermieden bzw. wieder aufgelöst wird. Die Art der Druckluftzufuhr kann kontinuierlich oder stoßweise erfolgen und führt jeweils zu einer kurzzeitigen Rüttelbewegung der Auslaufkegelinnenwandung, welche die Schüttgutabfuhr kontinuierlich unterstützt. Allerdings darf der Innenmantel aus Folienmaterial nicht derart angeordnet sein, daß während der druckluftunterstützten Schüttgutabfuhr eine Taschenbildung begünstigt wird. Um eine reibungsarme Fließfähigkeit des Schüttgutmaterials zu gewährleisten, wird daher der innenliegende Folienmantel oben fest eingespannt und am unteren Ende mittels Spannkonstruktionen, die in den verschiedensten Ausführungsformen bekannt sind, gehalten. Mit diesen Spannkonstruktionen sind jedoch auch Nachteile verbunden, die den Vorteil der Reibungsminimierung bei der Schüttgutentleerung teilweise wieder zunichte machen. So sind mitunter die zum Spannen benötigten Mittel im Kegelinneren angeordnet und stehen somit dem abfließenden Gut hinderlich im Wege. Zudem ist der konstruktive Aufwand für die Spannvorrichtungen relativ groß, womit auch ein hoher Wartungsaufwand verbunden ist.For bulk containers, such as tall silos in the floor area arranged outflow cones, the bulk material is in the lower area by the pending filling level strongly compressed, which leads to a bridge training can come in bulk. The overlying bulk material is held by the bridge training, so that further leakage of the Bulk material is prevented. For this reason, special precautions must be taken to be bridged at the outset To prevent bulk material discharge or, if this by correspondingly long storage times has arisen to break up again. Single-walled rigid spout can not afford this, which is why the conical spout is double-walled becomes. This is usually the inner funnel-shaped outlet surface made of air-permeable sheet material, so that between the entered outer airtight cone wall and the Innenkegelwandung Compressed air can flow into the bulk material cone space and thereby bridge formation is avoided or dissolved again. The type of compressed air supply can be continuous or intermittent and leads to one short-term shaking movement of the outlet cone inner wall, which the Bulk material removal continuously supported. However, the inner jacket may be off Foil material should not be arranged so that during the compressed air assisted Schüttgutabfuhr a pocket formation is favored. To a low-friction Flowability of the bulk material is therefore guaranteed the inner film jacket firmly clamped at the top and at the bottom by means of clamping constructions, which are used in various embodiments are known held. However, these clamping structures also have disadvantages connected, which has the advantage of minimizing friction during bulk material discharge partly ruined again. So are sometimes the to Clamping required means arranged in the cone interior and thus stand the draining good in the way. In addition, the design effort for the fixtures are relatively large, which also requires a high maintenance connected is.
Bei bewegten Silobehältern, beispielsweise auf Fahrzeugen tritt durch das Rütteln eine zusätzliche Verfestigung auf, die das Entleeren erschwert.In moving silo containers, for example on vehicles occurs by shaking an additional solidification, which makes emptying difficult.
Die US 4 413 758 A offenbart eine Auslaufeinrichtung mit innenliegender Auslauffläche aus Gewebematerial.US 4 413 758 A discloses an outlet device with inside outlet area made of fabric material.
Ein weiteres Problem der Auslaufeinrichtungen mit innenliegender luftdurchlässiger Auslauffläche aus Gewebematerial ist dadurch gegeben, daß das staubförmige oder körnige Schüttgut zu einem Verschleiß des Gewebematerials führt, weshalb es notwendig ist, dieses innenliegende Gewebematerial nach Verschleiß auszutauschen. Die Standzeiten für das Gewebematerial sind dadurch sehr gering.Another problem of the outlet devices with internal air-permeable Outlet surface of fabric material is given by the fact that the dusty or granular bulk material to a wear of the fabric material which is why it is necessary to recreate this internal fabric material Replace wear. The lifetimes for the fabric material are thereby very low.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Auslaufeinrichtung für Schüttgutbehälter zu schaffen, die das Schüttgut wirksam auflockert und ein Ausleeren des Schüttgutes gewährleistet und die einen geringen konstruktiven Aufwand erfordert, wobei die Standzeiten gegenüber dem Stand der Technik deutlich erhöht werden sollen. It is therefore an object of the present invention, an outlet device for To create a bulk material container that effectively loosens the bulk material and a Ensures emptying of the bulk material and a low constructive Requires effort, the service life compared to the prior art should be increased significantly.
Diese Aufgabe wird durch eine Auslaufeinrichtung mit den Merkmalen des Anspruches 1 gelöstThis object is achieved by a discharge device with the features of the claim 1 solved
Dabei ist vorgesehen, eine Auslaufeinrichtung zu schaffen, die einen kegelförmig nach unten sich auf einen engeren Querschnitt eines Anschlußstutzens für eine Förderleitung verengenden Auslauf aufweist, wobei die Auslaufeinrichtung reversibel mit dem Behälter verbunden ist und wobei in dem Auslaufkörper ein Schüsseleinsatz angeordnet ist, der einen oberen auskragenden Rand aufweist, der im Bereich der Kontaktfläche zwischen Behälter und Auslaufkörper klemmend gehalten wird. Der Schüsseleinsatz weist dabei an beiden Seiten kreisförmige Öffnungen auf, wobei im Bereich der Wandung des Auslaufkörpers ein Spalt zwischen dem Rand der Öffnung des Schüsseleinsatzes und der Wandung des Auslaufkörpers resultiert.It is envisaged to provide an outlet device which is a conical down to a narrower cross-section of a connecting piece for a delivery line narrowing outlet, wherein the outlet device reversibly connected to the container and wherein in the outlet body a Bowl insert is arranged, which has an upper projecting edge, the clamping in the area of the contact surface between the container and outlet body is held. The bowl insert has circular on both sides Openings, wherein in the region of the wall of the outlet body Gap between the edge of the opening of the bowl insert and the wall the outlet body results.
Die Wandung des Schüsseleinsatzes verläuftThe wall of the bowl insert runs
Durch einen Stutzen für Druckluft, der in dem Bereich des Auslaufkörpers vorgesehen ist, wo zwischen den Wandungen des Auslaufkörpers und des Schüsseleinsatzes ein Raum ausgebildet wird, wird Druckluft in die Auslaufeinrichtung eingeleitet, so daß das Schüttgut aufgelockert und Brücken aufgebrochen werden und das Schüttgut ablaufen kann, wobei dieser Vorgang durch die Druckluft zusätzlich beschleunigt wird. Through a nozzle for compressed air, which is provided in the region of the outlet body is where between the walls of the outlet body and the bowl insert a space is formed, compressed air is in the outlet device introduced, so that the bulk material loosened and broken bridges and the bulk material can drain, this process being due to the compressed air additionally accelerated.
In Abhängigkeit von der Materialbeschaffenheit des Schüsseleinsatzes kann eine Wölbung des Schüsseleinsatzes durch Beaufschlagung mit Druckluft hervorgerufen werden, so daß bei Einblasen der Druckluft mit periodischen Druckschwankungen ebenfalls Schwingungen oder auch ein Rütteln hervorgerufen werden kann, wodurch das Schüttgut auflockert wird.Depending on the material properties of the bowl insert can a curvature of the bowl insert caused by the application of compressed air be so that when blowing the compressed air with periodic pressure fluctuations also caused vibrations or jarring can be, whereby the bulk material is loosened up.
Der Schüsseleinsatz ist mit einer grobmaschigen Matte, vorzugsweise aus Edelstahl, Aluminium o. dgl. belegt. Diese Matte ist mit Streifen, vorzugsweise ebenfalls aus Edelstahl o. dgl. verstärkt, wobei durch die Streifen Löcher geführt sind, die mit entsprechenden Löchern im Schüsseleinsatz korrespondieren. Die übereinanderliegenden Löcher können auch mit einer Niete versehen sein, die die Matte und den Schüsseleinsatz miteinander verbindet, wobei in der Mitte der Niete eine Öffnung erhalten bleibt.The bowl insert is with a coarse mesh mat, preferably made Stainless steel, aluminum or the like. This mat is with stripes, preferably also made of stainless steel o. The like. Reinforced, with holes through the strips are guided, which correspond with corresponding holes in the bowl insert. The superimposed holes can also be provided with a rivet be, which connects the mat and the bowl insert, wherein in the Middle of the rivets an opening is maintained.
Die Auslaufeinrichtung ist mit dem Silobehälter vorzugsweise über einen Flansch mittels Augen- oder Hakenschrauben bzw. einer Schnellspanneinrichtung verbunden.The outlet device is preferably connected to the silo container via a Flange by eye or hook screws or a quick-release device connected.
Zwischen den Rändern von der Auslaufeinrichtung und dem Behälter ist eine Ringdichtung angeordnet, die zudem in eine an einem der Ränder umlaufenden Nut eingelegt sein kann, wobei die Ringdichtung natürlich zur Abdichtung herausragen muß. Die Ringdichtung beaufschlagt dabei auch den auskragenden Rand des Schüsseleinsatzes und fixiert diesen zusätzlich Es ist auch möglich, daß in den beiden gegenüberliegenden Rändern Ringdichtungen in entsprechende Nuten eingelegt werden.Between the edges of the outlet device and the container is a Ring seal arranged, which also circulates in one on one of the edges Groove can be inserted, the ring seal of course protrude to seal got to. The ring seal also acts on the cantilever Edge of the bowl insert and fix it in addition It is also possible that in the two opposite edges ring seals in corresponding Grooves are inserted.
Die Wirkung der erfindungsgemäßen Auslaufeinrichtung ist derart optimiert, daß auch bei abgewinkelten Anschlußstutzen die Ausleerung des Schüttgutes problemlos möglich ist.The effect of the outlet device according to the invention is optimized such that even with angled connecting pieces, the emptying of the bulk material easily is possible.
Der Schüsseleinsatz wird vorzugsweise aus Edelstahl oder Aluminium gefertigt. Es sind aber auch Kunststoffe geeignet, die über eine ausreichende mechanische Festigkeit und Abriebfestigkeit verfügen, wobei ggf. auch faserverstärkte und beschichtete Kunststoffe zum Einsatz kommen können, die durch die Oberflächenvergütung eine widerstandsfähige und reibungsarme Oberfläche erhalten. Auch Komposite aus verschiedenen Werkstoffen können zum Einsatz gelangen, um den unterschiedlichen Anforderungen nach mechanischer Festigkeit und Beständigkeit gegen Abrieb gerecht zu werden.The bowl insert is preferably made of stainless steel or aluminum. But there are also suitable plastics which have a sufficient mechanical Have strength and abrasion resistance, where appropriate, fiber-reinforced and coated plastics can be used by the surface coating obtained a resistant and low-friction surface. Composites made of different materials can also be used, to the different requirements for mechanical strength and resistance to abrasion.
Vorteilhafterweise wird gegenüber dem Stand der Technik, bei dem der Auslaufkörper mit Folie ausgekleidet wird, eine Taschenbildung vollständig unterbunden.Advantageously, over the prior art, in which the outlet body lined with foil, a pocket formation completely prevented.
Zudem läßt sich die erfindungsgemäße Auslaufeinrichtung vorteilhafterweise auch durch Nachrüstung eines Schüsseleinsatzes bei bestehenden Silobehältern schaffen, da dieser lediglich in den Flansch zwischen Behälter und Auslaufkörper eingespannt werden muß. Es sind keine zusätzlichen Befestigungspunkte für den Schüsseleinsatz notwendig.In addition, the outlet device according to the invention can be advantageously also by retrofitting a bowl insert in existing silo containers create, as this only in the flange between the container and outlet body must be clamped. There are no additional attachment points necessary for bowl use.
Das Bestehen des Spaltes zwischen den Wandungen ist bei allen Ausführungsformen, auch bei denen mit durch eine Ringdichtung geschlossenen Spalt, von wesentlicher Bedeutung, da nur durch die freie Beweglichkeit des Schüsseleinsatzes beim Beaufschlagen mit Druckluft der gewünschten Erfolg herbeigeführt werden kann.The existence of the gap between the walls is in all embodiments, even with those closed by a ring seal gap, Essential because only by the free movement of the bowl insert when pressurized with compressed air brought about the desired success can be.
Um das Bestehen des Spaltes sicherzustellen, ist es möglich zwischen beiden Wandungen Abstandshalter anzuordnen, die auch an dem Schüsseleinsatz festgelegt sein können.To ensure the existence of the gap, it is possible between the two Walls to arrange spacers, which are also fixed to the bowl insert could be.
Für bestimmte Anwendungen läßt sich zudem der Schüsseleinsatz vollständig herausnehmen, so daß sich überhaupt keine Gegenstände im Materialfluß befinden. For certain applications, in addition, the bowl insert can be completely take out so that there are no objects in the flow of material at all.
Die einfache konstruktive Ausgestaltung erlaubt zudem eine sehr einfache Reinigung, was insbesondere im Lebensmittel- und Chemiebereich von großer Bedeutung ist.The simple structural design also allows a very simple cleaning, which is especially important in the food and chemical industry is.
