Description

Schleuse mit Zellenrad an. L@rderanlagen für Schüttgut Bei Luftförderanlagen für Schüttgut wird das Fördergut in der Regel durch Schleusen. mit eaufenden Zellenrädern, und zwar bei Druclduftförderung in den Druckluftstrom eingeführt, bei Saugluftförderung aus dein unter Minderdruck stehenden Einsaughehälter ausgetragen.Lock with rotary valve on. Loading systems for bulk goods With air conveying systems For bulk goods, the conveyed goods are usually through locks. with rotating cell wheels, namely introduced into the compressed air flow with compressed air conveyance, with suction air conveyance discharged from your suction container which is under reduced pressure.

Zur Erzielung einer wirksamen Abdichtung hat man versucht, zwischen den Stirnflächen des Zellenrades und dem Gehäuse mit Deckeln abgeschlossene Räume zu bilden und diese unter gleichen oder höheren Druck zu setzen, als er in dem Förderraum herrscht. Die Erwartungen, die an diese Anordnung gestellt wurden, haben sich nicht nur nicht erfüllt, vielmehr sind neue Schwierigkeiten dadurch aufgetreten,. daß das trotzdem am Zellenrädumfang nach außen hin austretende feine Fördergut sich innerhalb der erwähnten abgeschlossenen Räume anstaut.In order to achieve an effective seal, attempts have been made between the end faces of the cellular wheel and the housing with lids closed spaces to form and to put this under the same or higher pressure than in the pumping chamber prevails. The expectations that were placed on this arrangement did not materialize just not met, rather new difficulties have arisen as a result. that the fine conveyed goods which nevertheless emerge outwards at the cell wheel circumference accumulates within the mentioned enclosed spaces.

Selbst bei Entladevorrichtungen an mit Saugluft betriebenen Förderanlagen für Schüttgut ist es beim Fördern feinkörnigen oder stark staubhaltigen Gutes trotz des herrschenden Unterdruckes bisher nicht möglich, den Staubaustritt nach außen hin am Zellenradumfang zu verhindern.Even with unloading devices on conveyor systems operated with suction air for bulk goods it is despite the conveyance of fine-grained or very dusty goods the prevailing negative pressure has not been possible so far, the dust escape to the outside to prevent the circumference of the bucket wheel.

Die Erfindung dient dem Zweck, diesen Übelstand zu beheben; sie besteht in der Ausbildung des innerhalb seines Gehäuses gelagerten und in Drehung versetzten Zellenrades mit je zwei Rundstegen an den äußeren Zellenwänden des Zellenrades und je einer Anzahl Luftkammern zwischen den beiden Rundstegen, die das zufolge Undichtigkeiten jeweils am inneren Rundsteg in sie @eintretea@de feinkörnige und staubartige Fördergut aufnehmen und es. bei der Umdrehung des Zellenrades dem ein- oder auszuschleusenden Hauptfördergutstrom_ durch eine abfallende Rinne wieder zuleiten.The purpose of the invention is to remedy this drawback; it consists in the formation of the supported within its housing and being rotated bucket wheel with two round bars at the outer cell walls of the cellular wheel and each having a plurality of air chambers between the two round bars that which according to leaks in each case fine-grained at the inner round bar in them @ eintretea @ de and pick up dusty conveyed goods and it. With the rotation of the star feeder the main conveyed material stream to be introduced or discharged through a sloping channel.

Eine Ausführungsform der Schleuse, an Luftförderanlagen für Schüttgut gemäß der Erfindung ist in der Zeichnung veranschaulicht. Abb. r zeigt einen Schnitt nach der Linie C-D von Abb.2 und A'bb. 2 einen Schnitt nach der Linie A-B von Abb. t.An embodiment of the lock on air conveying systems for bulk goods according to the invention is illustrated in the drawing. Fig. R shows a section according to the line C-D of Fig.2 and A'bb. 2 a section along the line A-B of Fig. t.

'Das innerhalb des Gehäuses gelagerte umlaufende Zellenrad b ist an den beidseitigen äußeren Zellenwänden mit je zwei Rundstegen c und d versehen. Dadurch wird zwischen diesen Stegen vermöge der Anordnung von Querstegen f eine Anzahl von Luftkammern e gebildet. Diese Luftkammern nehmen das zufolge von Undichtigkeiten an den inneren Rundstegen c in sie eintretende feinkörnige oder staubartige Fördergut auf. Bei der Umdrehung des Zellenrades b wird dieses abgesonderte feinkörnige oder staubartige Fördergut dadurch dem Hauptfördergutstrom wieder zugeleitet, daß die Luftkammern e des umlaufenden Zellenrades b nacheinander mit einer (oder mehreren) Rinne g in Verbindung gelangen, die in den abfallenden Teil der Schleuse hineinleitet. Bei den irt die Lufträume bzw. Kammern e übergetretenen Fördergutmengen besteht keine Neigung mehr, etwa über den zweiten Rundsteg d ins Freie überzutreten (Pfeilrichtungen I und II).The rotating cellular wheel b mounted inside the housing is provided with two round webs c and d each on the outer cell walls on both sides. As a result, a number of air chambers e is formed between these webs by virtue of the arrangement of transverse webs f. These air chambers absorb the fine-grained or dust-like conveyed material entering them as a result of leaks at the inner round webs c. During the rotation of the cell wheel b, this separate fine-grained or dust-like conveyed material is fed back to the main conveyed material flow in that the air chambers e of the revolving cell wheel b come into connection one after the other with one (or more) channel g, which leads into the sloping part of the sluice. In the case of the quantities of conveyed goods that have passed over the air spaces or chambers e, there is no longer any tendency to pass over the second circular web d into the open (arrow directions I and II).

Die Ausbildung gemäß der Erfindung kann in gleicher Weise und mit dem gleichen Er-' folg auch bei Entladevorrichtungen an Saugförderanlagen Verwendung finden.The training according to the invention can in the same way and with the same success is also used with unloading devices on suction conveyor systems Find.
