Description
Förderrinne zum Fördern von pulverförmigem oder feingrießigem Massengut, durch deren porösen Boden ein. gasförmiges Druckmittel in das Fördergut eingeleitet wird Es ist bekannt, Rinnen durch beispielsweise unbalante Wellen o. dgl. in Schwingungen zu versetzen, um auf diese Weise seine leichte und gleichmäßige Förderung des Gutes zu bewirken. Ebenso ist auch bereits vorgeschlagen worden, Wände von Behältern o. dgl. zu Schwingungen zu erregen, um bei Brückenbildungen ein Hängenbleiben des in diesen Behältern eingelagerten pulverförmigen Gutes zti vermeiden und den glatten Ablauf dieses Gutes herbeizuführen.Conveyor trough for conveying powdery or fine-grained bulk goods, through their porous bottom. gaseous pressure medium introduced into the conveyed material It is known that grooves, for example, by unbalanced waves or the like in vibrations to move in order in this way its easy and even conveyance of the goods to effect. Likewise, it has also already been proposed that walls of containers o. Like. To excite vibrations in order to prevent the in Avoid powdery goods stored in these containers and use the smooth ones To bring about the expiration of this good.
Bei pneumatischen Rinnen hat es sich nun gezeigt, daß namentlich bei einem Fördergut von unterschiedlichen Korngrößen die gröberen Teilchen das Bestreben haben, zu Boden zu sinken, um alsdann auf dem Boden der Rinne entlang zu fließen. Dadurch aber kann es vorkommen, daß eine Entmischung des Fördergutes eintritt oder aber noch eine Trennung zwischen den feinen und groben Bestandteilen, die im Interesse einer glatten und guten Förderung unbedingt vermieden werden muß.In the case of pneumatic channels, it has now been shown that in particular at a conveyed material of different grain sizes the coarser particles the endeavor have to sink to the bottom in order to then flow along the bottom of the channel. As a result, however, it can happen that the conveyed goods separate or but still a separation between the fine and coarse ingredients that are in the interest smooth and good promotion must be avoided at all costs.
Zur Beseitigung dieser NachteÄle wird die Rinne oder Teile derselben zur Vermeidung einer Entmischung des Gutes oder einer Triennung der groben und feinen Bestandteile unter Zwischenschaltung elastischer energicspeichernder Glieder mit Hilfe entsprechender Arbeitsmittel, wie unbalante Wellen o. dgl., zu nicht fördernden Schwingungen erregt. Die Einleitung der Vibration erfolgt bei diesen pneumatischen Rinnen lediglich zu dem Zweck, die Entmischung des Gutes zu verliindern.The gutter or parts of it are used to eliminate these nights to avoid segregation of the material or a separation of the coarse and fine Components with the interposition of elastic energy-storing members The help of appropriate work equipment, such as unbalanced waves or the like, not to be promoted Vibrations excited. The vibration is initiated with these pneumatic ones Gutters only for the purpose of reducing the segregation of the goods.
Diese arbeitsmittel zur Erzeugung der Schwingungen können am Boden der Förderrinne so, befestigt und angeordnet weiden, daß die Rinne und mit ihr das Fördergut selbst in schnell vibrierende Bewegungen oder Schwingurigen versetzt wird, und zwar beispielsweise in "Kreisschwingungen in der seaikrechten oder auch in der _ waagerechten Ebene.These tools for generating the vibrations can be on the ground the conveyor trough so attached and arranged that the trough and with it the The conveyed material itself is set in rapidly vibrating movements or vibrations, for example in "circular vibrations in the seaikrechte or in the _ horizontal plane.
Ein Ausführungsbeispiel veranschaulicht die beiliegende Zeichnung in schematischer Darstellung in einem Querschnitt. .The accompanying drawing illustrates an exemplary embodiment in a schematic representation in a cross section. .
Die Rinne a ist, wie bekannt, ausgebildet-Sie Sie ist mit einer Schicht b aus porösem Baustoff versehen, auf der das Fördergut mittels eines gasförmigen Druckmittels fließbar gemacht wird, für dessen Zulauf der Luftraum c dient. Die Rinne kann auf einer Plattform d gelagert sein, wobei am Rinnenboden unbalante Welle f drehbar gelagert ist. Die Plattform d selbst ruht dabei auf elastischen Gliedern g, die im vorliegenden Beispiel als Federn ausgebildet sind. Wird die Rinne in Schwingungen versetzt, dann wird das Bestreben eines jeden gröberen Kornes, durch seine Schwerkraft nach unten zu sinken, aufgehoben, so daß es gleichmäßig mit dem fließbar gemachten feinen Gut ohne Entmischung und ohne Trennung nach Korngrößen die Rinne abwärts fließt.The groove a is, as is known, formed - it is with a layer b made of porous building material, on which the conveyed material by means of a gaseous Pressure medium is made flowable, for the inlet of which the air space c is used. the Channel can be mounted on a platform d, with unbalanced wave at the bottom of the channel f is rotatably mounted. The platform d itself rests on elastic members g, which in the present example are designed as springs. Will the gutter vibrate displaced, then the striving of every coarser grain, by its gravity to sink down, lifted so that it is evenly made with the flowable fine goods without segregation and without separation according to grain size down the channel flows.
