Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Austragen von schleißendem Gut aus unter Unterdruck stehenden Räumen, z. B. Abscheidern pneumatischer Förderanlagen. The invention relates to a device for discharging abrasive material from rooms under negative pressure, e.g. B. Separators pneumatic Conveyor systems.
Bisher wurden für die Abscheidung aus solchen Anlagen entweder Zellenradschleusen oder Sammelräume benutzt, die mittels unter Gutlast öffnender Verschlußmittel, z. B. Klappen, abgeschlossen waren. So far, either rotary feeders have been used for separation from such systems or collecting spaces are used, which by means of closing means that open under good load, z. B. flaps, were completed.
Dabei zeigte sich der Nachteil, daß die Zellenradschleusen durch die stark verschleißende Wirkung mancher Fördergüter, z. B. Schlacke, sich sehr schnell abnutzen. so daß erhebliche Zeit und Kosten für Reparaturen anfielen. Der Nachteil der durch Klappen od. dgl. abgeschlossenen Sammelräume liegt in der großen Bauhöhe, die erforderlich ist. um eine Gutsäule anzustauen, deren Gewicht die Kraft des Unterdrucks überwiegt. Dieses ist erforderlich, um ein ( neun der Klappe zu erzielen. This showed the disadvantage that the rotary feeders through the strong wear and tear of some conveyed goods, e.g. B. slag, very much wear out quickly. so that considerable time and expense were incurred for repairs. Of the The disadvantage of the collecting spaces closed by flaps or the like is that they are large Overall height that is required. to stow a column of manure, the weight of which is the force of the negative pressure predominates. This is required to close a (nine of the flap achieve.
Nach der Erfindung werden diese Nachteile dadurch vermieden, daß zwischen den Abscheider und Sammelraum eine Vorrichtung zur Förderung abgegrenzter Einzelmengen, z. B. eine Zellenradschleuse, angeordnet wird, bei der zwischen dem bewegten Teil und dem Gehäuse ein gegenüber sonstigen Verhältnissen großes Spiel belassen wird. According to the invention, these disadvantages are avoided in that between the separator and collecting space a device for conveying delimited Single quantities, e.g. B. a rotary valve, is arranged in which between the moving part and the housing a big game compared to other conditions is left.
An das Fördermittel braucht nur noch ein Sammelraum geringer Höhe angeschlossen zu werden, da die anfallende Gutmenge selbst als Abdichtung wirkt, so daß die Klappe ihrer natürlichen Undichtigkeit wegen entlastet ist.Only a small collecting space is needed for the funding to be connected, as the amount of material produced acts as a seal itself, so that the flap is relieved of its natural leakage.
Die Erfindung ist an einem Ausführungsbeispiel, das in der Abbildung dargestellt ist, näher erklärt. The invention is based on an embodiment that is shown in the figure is shown, explained in more detail.
Über dem Bunker 5 ist der Abscheider I einer pneumatischen Förderanlage angeordnet. Zwischen dem Abscheider und dem Sammelraum 3 befindet sich die Zellenradschleuse 4. Der Sammelraum ist durch die Klappe 2, die durch ein Gewicht belastet sein kann, ahgeschlossen. Above the bunker 5 is the separator I of a pneumatic conveyor system arranged. The rotary valve is located between the separator and the collecting chamber 3 4. The collecting space is through the flap 2, which can be loaded by a weight, closed.
Das Spiel des Zellenradläufers gegen sein Gehäuse ist so groß bemessen, daß ein Schleißen weitgehend verhindert, andererseits aber die Wirkung erzielt wird, die Fortpflanzung des Unterdrucks in den Sammelraum 3 hinein zu erschweren. Bei der Zuteilung voll Gut in den Sammelraum 3 hinein wird ein Polster gebildet, das abdichtende Eigenschaften besitzt, so daß die durch die Undichtigkeiten der Klappe 2 eintretende Luft einen Druckausgleich unterhalb des Gutpfropfens erzielt, sich aber durch das Gut hindurch in dem oberen Teil des Sammelraumes wegen der bremsenden Wirkung der Zellenradschleuse gegen den Abscheider nicht auswirken kann. Es ist daher nur eine geringe Bauhöhe des Sammelraumes 3 erforderlich, da die Klappe 2 nach Anfall schon geringer Gutmengen nicht mehr durch Unterdruck belastet ist. Bereits kleine Gutmengen bewirken daher die Oeffnung der Klappe. The clearance between the rotary valve and its housing is so large that that wear is largely prevented, but on the other hand the effect is achieved, to make it difficult for the negative pressure to propagate into the collecting space 3. at the allotment full of good in the collecting space 3 into a cushion is formed that Has sealing properties, so that the leaks in the flap 2 incoming air achieves pressure equalization below the crop plug, itself but through the good in the upper part of the collecting space because of the braking The effect of the rotary valve against the separator cannot have any effect. It is therefore only a small overall height of the collecting space 3 is required, since the flap 2 is no longer burdened by negative pressure after a small amount of material has been produced. Already small amounts of material therefore cause the flap to open.
Bei den meisten Anlagen dürften die natürlichen Undichtigkeiten zwischen Klappe und Sammelraum ausreichen, um die gewünschte Wirkung herbeizuführen. Da, wo dies nicht der Fall ist, müssen künstliche Undichtigkeitsquerschnitte angeordnet werden, die gegebenenfialls einstellbar zu machen sind. Sie sind in dem untersten Bereich des Sammelraumes 3 anzuordnen, um schon bei geringen Mengen Gutes die Polsterwirkung zu erzielen. Most systems are likely to have natural leaks between The flap and collecting space are sufficient to produce the desired effect. There, where this is not the case, artificial leakage cross-sections must be arranged which can be made adjustable if necessary. You are in the lowest To arrange the area of the collecting space 3 in order to have the cushioning effect even with small quantities of goods to achieve.
