Abstract
Description
Beschreibung und Erlauterung z; Patentanmeldunc "Drucksenderstation mit kontinuierlich arbeitende Förderstrom" Es ist bekannt, Drucksender zum Transport von Schüttgütern zu benutzen.Description and explanation z; Patent pending "pressure transmitter station with continuously operating flow "It is known to use pressure transmitters for transport to be used by bulk goods.
Jedoch ist die Kontinuität des Förderstroms bei dem Fördervorgang in den meisten Fällen nicht erforderlich.However, there is the continuity of the flow in the delivery process not required in most cases.
Es ist weiterhin bekannt, Tandemsender zu benutzen, die eine gewisse Kontinuität des Materialstroms gewährleisten.It is also known to use tandem transmitters that have a certain Ensure continuity of the material flow.
Jedoch im Berg- und Tunnelbau, wo diese Drucksendestationen benutzt werden, um dämm- und feuerfestes Material über große Strecken zu transportieren und mit einer Flüssigkeit in Verbindung zu bringen, um ein homogenes Dammgefüge zu erhalten, sind die Ausschaltzeiten von nur wenigen Sekunden sehr schädlich.However, in mining and tunneling, where these pressure transmission stations are used in order to transport insulation and fireproof material over long distances and to bring it into contact with a liquid to form a homogeneous dam structure the switch-off times of just a few seconds are very harmful.
Das Verhältnis von Luft zu transportierender Masse wirkt während dieser Zeit derart unterschiedlich, daß in den meisten Fällen ein Wegfließen oder ein spezifisches Verdünnen der Dammassen die Folge ist, so daß die erforderliche Festigkeit des Dammes nicht mehr gewährleistet ist.The ratio of air to transported mass acts during this Time so different that in most cases a flow away or a specific one Thinning of the dam masses is the result, so that the required strength of the dam is no longer guaranteed.
Drucksender, die mit Füllstandsmessern ausgerüstet sind und überlappende Zuteilungen bewirken, haben den Nachteil, daß die Verschlußorgane im Materialstrom geschlossen werden müssen.Pressure transmitters equipped with level gauges and overlapping Cause allocations have the disadvantage that the closure members in the material flow need to be closed.
Der Verschleiß der Verschlußorgane ist sehr hoch, und die Verfügbarkeit solcher Drucksender-Anlage ist für den Bergbau nicht geeignet.The wear and tear of the closure members is very high, and so is the availability Such a pressure transmitter system is not suitable for mining.
Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, eine Drucksenderstation mit kontinuierlich arbeitendem Förderstrom zu verwenden, wobei die Gewähr gegeben ist, daß die Verschlußorgane im förderstromfreien Raum betätigt werden.For this reason, the invention proposes a pressure transmitter station to be used with a continuously working flow rate, with the guarantee given is that the closure members are actuated in the flow-free space.
In der beiliegenden Zeichnung ist dargestellt: Mit (1) die obere Zuteilschnecke mit (2) der Schieber oberhalb vom Drucksender mit (3) ein Füllstandsmesser oben mit (4) ein Füllstandsmesser unten mit (5) der Schieber unten mit (6) die Zuteilschnecke für den Pufferbehälter mit (7) der Pufferbehälter mit (8) die Zuteilschnecke vom Pufferbehälter in die pneumatische Förderleitung mit (9) pneumatische Förderleitung mit (10) Druckluftzuteilung mit (11) Druckausgleichsleitung, die vom Druckluftanschluß (10) mit dem Steuerventil (12) in den Druckbehälter mündet mit (12) Steuerventil mit (13) Steuerventil, das eine Druckausgleichsleitung von dem Druckluftanschluß (10) auf die untere Zuteilschnecke (6) aufgibt.The attached drawing shows: With (1) the upper feed screw with (2) the slide above the pressure transmitter with (3) a level meter above with (4) a level meter below with (5) the slide below with (6) the metering screw for the buffer container with (7) the buffer container with (8) the feed screw from Buffer container in the pneumatic delivery line with (9) pneumatic delivery line with (10) Compressed air distribution with (11) pressure equalization line coming from the compressed air connection (10) with the control valve (12) opens into the pressure vessel with (12) control valve with (13) control valve that connects a pressure equalization line from the compressed air connection (10) gives up on the lower feed screw (6).
mit (14) Füllstandsmesser.with (14) level meter.
Arbeitsweise der erfindungsgemäßen Ausführung: Der Schieber (2) öffnet, die Zuteilschnecke (1) läuft an und füllt den Drucksender bis der Füllstandsmesser (3) "voll" meldet. (1) wird gestoppt, (2) schließt, das Steuerventil (12) öffnet sich, der Schieber unten (5) öffnet, die Zuteilschnecke (6) läuft an,und der Pufferbehälter (7) wird beschickt.Mode of operation of the embodiment according to the invention: The slide (2) opens, the metering screw (1) starts up and fills the pressure transmitter up to the level gauge (3) reports "full". (1) is stopped, (2) closes, the control valve (12) opens opens, the slide at the bottom (5) opens, the feed screw (6) starts up, and the buffer container (7) is loaded.
Die Förderschnecke (8) füllt aus dem Pufferbehälter in die Förderleitung (9).The screw conveyor (8) fills from the buffer tank into the conveyor line (9).
Die Druckluft (10) wird gleichzeitig zugegeben.The compressed air (10) is added at the same time.
Sobald (4) "Leer" meldet, schließt (12), (5) schließt ebenfalls, das Steuerventil (13) geht auf, der Schieber (2) oben öffnet, und der Fördervorgang durch (1) beginnt.As soon as (4) reports "Empty", (12) closes, (5) also closes that The control valve (13) opens, the slide (2) opens at the top, and the delivery process begins with (1).
Die Zuteilschnecke (6) hat gleiche oder größere Leistung als die Zuteilschnecke (8), so daß der Pufferbehälter (7) einen Vorrat garantiert, der über die Füllzeit des Drucksenders reicht.The feed screw (6) has the same or greater performance than the feed screw (8), so that the buffer container (7) guarantees a supply that lasts over the filling time of the pressure transmitter is enough.
(14) kennzeichnet einen. Füllstandsmesser, der beim Überschreiten von (7) (6) stillsetzt.(14) indicates a. Level meter that when exceeded of (7) (6) stops.
Durch diese erfindungsgemäße Maßnahme ist die Gewähr einer kontinuierlichen Förderung gegeben und des Schließens der Verschlußorgane (2) und (5) im materialstromfreien Raum.This measure according to the invention ensures a continuous Promotion given and the closing of the closure members (2) and (5) in the material flow-free Space.
