Description

Bei zahlreichen technischen Verfahren werden mittels Förderschnecken feinkörnige bis staubförmige Stoffe von einem Behälter in einen anderen bewegt, insbesondere bei der Zuführung von feinkörnigen Brennstoffen in Gaserzeuger oder Feuerungen. In numerous technical processes, screw conveyors moving fine-grained to dusty substances from one container to another, especially when feeding fine-grain fuels into gas generators or Furnaces.

Dabei wirkt sich oft sehr störend aus, daß auch in den Förderpausen, also wenn die Schnecke sich nicht dreht, feinkörnige Stoffe nachrutschen. Dies ist besonders dann der Fall, wenn die Schnecke kurz ist oder ein Druckgefälle vom Bunker zu dem Behälter, in den gefördert wird, vorhanden ist. This often has a very disruptive effect that even in the breaks in funding, so if the worm does not turn, fine-grained substances slide behind. This is especially the case when the screw is short or there is a pressure gradient from the bunker to the container into which it is conveyed is present.

Es wurde gefunden, daß man das unerwünschte Nachfördern von feinkörnigen bis staubförmigen Stoffen ohne Einbau von den Betrieb störenden Schiebern, Hähnen usw. einfach dadurch beseitigen kann, daß die Schnecke an der Aufnahmeseite von einem so großen Blechringabschnitt überdeckt ist, daß bei einer bestimmten Haltestellung der Schnecke der Blechringabschnitt die i)ffnung des Bunkers zum Schneckengehäuse gerade verschließt. It has been found that the unwanted replenishment of fine-grained to dusty substances without the installation of slides and taps that interfere with operation etc. can easily be eliminated by the fact that the screw on the receiving side of such a large sheet metal ring section is covered that at a certain holding position the screw the sheet metal ring section i) the opening of the bunker to the screw housing just locked.

Dabei ist es nicht einmal nötig, daß der Blechringabschnitt sehr dicht abschließt. Selbst bei einigen Millimetern Undichtigkeit rutscht praktisch kein Feinkorn mehr nach, da beim beginnenden Nachrutschen die zurückgehaltene gröbere Körnung dem übrigen Korn sehr rasch den Weg versperrt.It is not even necessary for the sheet metal ring section to be very tight concludes. Even with a few millimeters of leakage, practically nothing slips Fine grain more, because when it begins to slide, the coarser one that is held back Grain blocks the way for the rest of the grain very quickly.

An Hand der Zeichnung sei die Erfindung näher erläutert, wobei Abb. ia die Draufsicht und Abb. Ib einen seitlichen Schnitt zeigt. Der Bunker b für Feinkohle sitzt auf dem Schneckengehäuse e, in welchem sich die Schnecke a durch Antrieb d bewegt. Der gemäß der Erfindung angeordnete Blechringabschnitt c ist auf der Schnecke a aufgeschweißt. The invention is explained in more detail with reference to the drawing, with Fig. generally the top view and Fig. Ib shows a side section. The bunker b for fine coal sits on the worm housing e, in which the worm a is driven by drive d emotional. The sheet metal ring section c arranged according to the invention is on the worm a welded on.

Eine etwa verringerte Leistung der Schnecke kann leicht durch Erhöhung der Umdrehungszahl der Schnecke ausgeglichen werden. A somewhat reduced performance of the screw can easily be increased by increasing the number of revolutions of the worm.

Die Vorrichtung ist einfach in der Herstellung und im Betrieb und wirksam auch bei großem Druckgefälle. The device is simple to manufacture and operate and effective even with large pressure drops.

PATENTANSPRUCN: Vorrichtung zum Fördern von feinkörnigen bis staubförmigen Stoffen mittels Schnecke aus einem auf dem Schneckenrohr sitzenden Behälter oder Bunker in einen anderen Behälter, dadurch gekennzeichnet, daß an der Aufnahmeseite die Schnecke von einem so großen Blechringabschnitt überdeckt ist, daß während der Förderpause ein Nachrutschen der feinkörnigen bis staubförmigen Stoffe verhindert wird. PATENT CLAIM: Device for conveying fine-grained to powdery Substances by means of a screw from a container sitting on the screw tube or Bunker in another container, characterized in that on the receiving side the screw is covered by such a large sheet metal ring section that during the Pause in conveyance prevents the fine-grained to dusty substances from sliding down will.
