Abstract

Mechanism comprises a compressed-air receiver (3) equipped with an upper large impulse diaphragm (6). This is coupled by a valve stem (9) to the impulse-emitting valve membrane (7) and is spring-loaded (10) shut, until the receiver is filled via the air throttle valve (5). This releases an impulse via an diaphragm. The device allows the duration of the impulse to be very short, and avoids the need for large-dia. supply pipes, in addition to giving a very low consumption.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Pulsator für Schüttgutbunker" Es ist bekannt, Brückenbildungen in Silos durch Viberatoren oder Belüftungen zu vermeiden."Pulsator for bulk material bunker" It is known to form bridges in Avoid silos through viberators or ventilation.

Viberationen und Belüftungen sind Hilfsmittel, die jedoch keine schockartige Wirkung verursachen.Viberations and ventilation are aids, but not shock-like Cause effect.

Um Brückenbildungen in Schüttgutsilos durch eine schockartige Gasimpulswirkung zum Einsturz zu bringen, wird erfindungsgemäß vorgeschlagen, eine Vorrichtung entsprechend beiliegender Skizze zu verwenden.To create bridges in bulk material silos through a shock-like gas pulse effect to bring it to collapse is proposed according to the invention, a device accordingly to use the enclosed sketch.

In der beiliegenden Skizze ist dargestellt: mit 1) der Schüttgutsilo, mit 2) der Druckluftpulsator, mit 3) der Druckluft speicher, mit 4) die Druckluftzufuhr, mit 5) ein Druckluftdrosselventil, mit 6) eine elastische obere, große Hubmanschette, mit 7) eine elastische Ventilmembrananordnung, mit 8) der Druckluftimpuls, mit 9) die verbindende Ventilstange zwischen Hubmanschette 6 und Ventilmembrane 4 mit Vorspannfeder 10.The attached sketch shows: with 1) the bulk material silo, with 2) the compressed air pulsator, with 3) the compressed air reservoir, with 4) the compressed air supply, with 5) a compressed air throttle valve, with 6) an elastic upper, large lifting sleeve, with 7) an elastic valve membrane arrangement, with 8) the compressed air pulse, with 9) the connecting valve rod between the lifting sleeve 6 and the valve membrane 4 with a pretensioning spring 10.

Arbeitsweise der erfindungsgemäßen Ausführung: Der Druckluftpulsator ist so ausgelegt, daß er für das entsprechende Silobunkervermögen einen entsprechenden hohen Impuls durch freiwerdende Druckluftmenge ausstoßen kann.Mode of operation of the embodiment according to the invention: The compressed air pulsator is designed in such a way that it has a corresponding silo capacity for the corresponding silo bunker capacity can emit high impulses due to the amount of compressed air being released.

Der Druckluftspeicher 3 wird über die Druckluftzuführung 4 und das eingebaute Druckluftventil 5 entsprechend der Drosseleinstellung schneller oder langsam gefüllt.The compressed air reservoir 3 is via the compressed air supply 4 and the built-in compressed air valve 5 according to the throttle setting faster or slowly filled.

Der Speicher besitzt 2 Membrananordnungen, die obere, größere Membrane 6 und die Ventilmembrane 7, die gegenläufig arbeiten.The memory has 2 membrane arrangements, the upper, larger membrane 6 and the valve membrane 7, which work in opposite directions.

Diese sind durch die Ventilstangen 9 miteinander verbunden.These are connected to one another by the valve rods 9.

Die obere, größere Membrane wird durch den ansteigenden Innendruck nach oben, vorzugsweise gegen eine Federabstützung, durchgebogen.The upper, larger membrane is created by the increasing internal pressure bent upwards, preferably against a spring support.

Aufgrund des größeren Durchmessers nimmt die obere Membrane über die Ventilstange die untere elastische Membrane 7 nach oben.Due to the larger diameter, the upper membrane takes over the Valve rod the lower elastic membrane 7 upwards.

Da die untere Membrane elastisch ausgeführt ist, bleibt der Rand dieser Membrane zunächst auf dem Behälterboden abdichtend angepreßt liegen, während der Teller sich elastisch nach oben durchbiegt.Since the lower membrane is made elastic, the edge of this remains The membrane is initially pressed against the container bottom in a sealing manner, during the Plate bends elastically upwards.

Erst nach Erreichen einer großen Verformung und Durchbiegung hebt der elastische Ventilteller der unteren Membrane schlagartig ab und geht nach dem Abheben in die Ausgangsform zurück.Only after reaching a large deformation and deflection does it lift the elastic valve disk of the lower membrane suddenly drops and goes to the Take off back to the original shape.

Dadurch wird der Druckluftimpuls durch die freigegebene Öffnung schlagartig über den vollen Querschnitt in den Schüttgutbunker abgeleitet.As a result, the compressed air pulse is suddenly released through the opening diverted over the full cross-section into the bulk material bunker.

Durch diese Vorrichtung wird ein sehr harter und kurzer Luftdruckimpuls erzeugt.This device creates a very hard and short pulse of air pressure generated.

Durch diesen Impuls wird der Brückenraum im Silo schockartig durch einen Druckluftimpuls beaufschlagt, erzeugt eine Impulswirkung auf die Schüttgutbrücke und bringt diese zum Einsturz.This impulse causes the bridge space in the silo to burst through When a compressed air pulse is applied, it creates a pulse effect on the bulk material bridge and brings it to collapse.

Diese beschriebene erfindungsgemäße Einrichtung hat gegenüber den normalen Druckluftbedüsungseinrichtungen den besonderen Vorteil, daß 1. die Impulsdauer sehr kurz sein kann, da in einer sehr kurzen Zeit genügend Druckluft aus dem Reservoir-Druckluftspeicher impulsartig zur Verfügung steht.This described device according to the invention has compared to the normal compressed air nozzle devices have the particular advantage that 1. the pulse duration can be very short, since there is enough compressed air in a very short time is available in pulses from the reservoir compressed air storage.

2. Bei einer Zufuhr durch Rohrleitungen wäre ein sehr großer Durchmesser notwendig und somit auch große Ventileinheiten, um diesen gleichen Impuls ohne Druckverlust in der gleichen Zeiteinheit wirksam werden zu lassen, der aus dem Speicher direkt gegen die Schüttgutbrückenbildung ausfließt.2. A pipeline supply would have a very large diameter necessary and therefore also large valve units in order to achieve this same impulse without pressure loss take effect in the same unit of time that is taken from memory directly flows out against the bulk material bridge formation.

3. Diese beiden angeführten Vorteile führen dazu, daß mit wesentlich weniger Druckluftverbrauch die Schüttgutbrücke zum Einsturz gebracht werden kann.3. These two cited advantages mean that with essential less compressed air consumption the bulk material bridge can be brought to collapse.

Die Druckluft-Kostensenkung durch diese erfindungsgemäße Vorrichtung ist sehr wesentlich.The compressed air cost reduction through this device according to the invention is very essential.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausführungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, den Druckluftimpuls so an einem Schüttgutbunker anzusetzen, daß ein Druckluftspeicher, der mit Differentialmembranen ausgerichtet ist, den Druckluftimpuls ohne Druckverlust durch Ventile und Zuführungsrohrleitungen und ohne Steuerbefehl selbsttätig auslöst.Of course, the invention is not limited to the above in detail shown and described embodiments are limited, but there are numerous Changes possible without deviating from the basic idea of the compressed air pulse at a bulk material bunker so that a compressed air reservoir with differential diaphragms aligned is the compressed air pulse without pressure loss through valves and supply pipes and triggers automatically without a control command.
