Description

Gegenstand der Erfindung ist ein Schneckenförderer als Beschickungsvorrichtung in Räume unterschiedlichen Druckes, bei dem am Austrittsende ein Fördergutpfropfen gebildet wird.The invention relates to a screw conveyor as a charging device in rooms with different pressures, at which a material plug at the outlet end is formed.

Es ist eine Beschickungsvorrichtung für pneumatische Förderleitungen bekannt, die aus einer in dem Förderkanal umlaufenden Schnecke besteht, vor der in angemessenem Abstand von der Förderleitung ein Fördergutpfropfen zum Zweck der Abdichtung gebildet wird. Diese bekannte Beschickungsvorrichtung ist ausdrücklich nur für feuchtes. leicht ballendes Gut bestimmt. welches besonders zur Pfropfenbildung neigt. Die Vorrichtung ist aber nicht anwendbar bei trockenem Staubgut, weil dieses am Ende der Schnecke ohne jegliche Pfropfenbildung aus dem Förderkanal abfließen würde. L m diesen Mangel zu beseitigen, schlägt die Erfindung vor. den Pfropfenraum am Auslaß des Schneckenrohres durch einen feiler- oder gewichtsbelasteten Teller abzuschließen.It is a loading device for pneumatic conveying lines known, which consists of a rotating in the conveyor channel screw, before At a reasonable distance from the conveying line, a plug of conveyed material for the purpose of Sealing is formed. This known loading device is explicit only for damp. Slightly balling of the goods is determined. which especially for plug formation tends. The device is not applicable to dry dust, because this at the end of the screw flow out of the feed channel without any plug formation would. The invention proposes to eliminate this deficiency. the plug room at the outlet of the screw tube through a plate loaded with filing or weight complete.

Abschlußteller am Ende von Schneckenrolirförderern sind zwar bekannt, doch dienen diese Abschlußteller nur als Rückschlagventil und nicht, wie im Falle der Erfindung, dazu. eine Pfropfenbildung zu fördern. Bei der bekannten Vorrichtung ist mangels' jeglichen hierfür vorgesehenen Raums im Anschluß an das Schneckenende- eine Pfropfenbiidung überhaupt nicht möglich.End plates at the end of screw roller conveyors are known but these end plates only serve as a check valve and not, as in the case of the invention, in addition. promote plug formation. In the known device in the absence of any space provided for this purpose in connection with the end of the screw plug formation is not possible at all.

In der Zeichnung ist der Gegenstand der Erfindung an Hand von zwei Ausführungsbeispielen veranschaulicht. Es zeigt Abb. i den Schnitt durch eine Schleusvorrichtung mit einer Schnecke, Abb. 2 eine Ausführungsart mit zwei Schnecken.In the drawing, the subject matter of the invention is based on two Exemplary embodiments illustrated. Fig. I shows the section through a lock device with one screw, Fig. 2 an embodiment with two screws.

Die Schnecke a arbeitet in einem Rohr b. in dem sie mit geringem Spiel läuft. Die Schnecke a ragt teilweise in dieses Rohr ein und läßt an einem Ende einen Raum c frei. in dem sich mit Unterstützung des federbelasteten Tellers d (Feder e) ein Gutpfropfen bildet. Dieser Gutpfropfen gewährleistet einen ständigen Abschluß gegen den unterschiedlichen Druck, der in dem Raum hinter dem Abschlußteller d herrscht.The screw a works in a tube b. in which they have little play runs. The screw a partially protrudes into this tube and leaves one at one end Room c free. in which with the support of the spring-loaded plate d (spring e) forms a plug of good. This crop plug ensures a permanent closure against the different pressure that prevails in the space behind the end plate d.

Das Gut wird über den Einlauf f der Schnecke a zugeführt. Die Vorrichtung ist gedacht für solche Fälle. in denen zwischen Einlauf f und Auslaß g Druckunterschiede überwunden werden müssen. In Abb. z wird das Gut über zwei Schnecken a, die in Rohren b arbeiten, vom Einlauf f zum Auslaß g gefördert. Dabei kann sowohl am Ende des Rohres b der ersten Schnecke als auch am Ende der darunterliegenden zweiten Schnecke ein federbelasteter Abschlußteller d vorgesehen sein.The material is fed to the screw a via the inlet f. The device is intended for such cases. in which between inlet f and outlet g pressure differences must be overcome. In Fig.z the material is about two augers a, which are in tubes b work, promoted from inlet f to outlet g. Both at the end of the Tube b of the first screw as well as at the end of the second screw below a spring-loaded end plate d may be provided.

Es ist ferner denkbar, daß außer dem freien Raum c am Ende des Rohres b weitere freie Räume in demselben Rohr dadurch gebildet «-erden, daß ein oder mehrere Gänge der Schnecke a ausgelassen werden. Auch in einem solchen Raum wird sich dann ein Gutpfropfen bilden.It is also conceivable that in addition to the free space c at the end of the tube b further free spaces are formed in the same pipe by the fact that one or more Threads of the screw a are omitted. Even in such a room it will be form a plug of good.
