Description

Reschreibung und Erläuterung zur Patent- und @ilfagebrauchsmusteranmeldung, "Vorrichtung zur Erkennung und gleichzeitiger Beseitigung von Verstopfern in Zyklonausläufen." Zyklone zur Abscheidung von insbesondere pulverförmigem Material, so wie auch I:olzstaub, neigen des öfteren zur Brückenbildung und somit zur Verstopfung im Zyklonauslauf.Description and explanation of the patent and utility model registration, "Device for the detection and simultaneous removal of blockages in cyclone outlets." Cyclones for the separation of especially powdery material, as well as I: wood dust, often tend to bridge and thus to blockage in the cyclone outlet.

Es ist bereits versucht worden, mit klopf- und Rühreinrichtungen diese Verstopfer zu beseitigen.Attempts have already been made with knocking and stirring devices Eliminate clogs.

Doch sind bei klebefreudigen Gütern diese Einrichtungen nicht wirksam.However, these devices are not effective for goods that are easy to stick.

Hieraus resultieren insbesondere bei Zyklonen hinter Holztrockner-Anlagen vielfach elbstentzünu1ungen, die zu erheblichen Brandschäden führen können.This results in particular in the case of cyclones behind wood dryer systems often self-inflamations, which can lead to considerable fire damage.

Um diese Nachteile der ständigen rartlmg und der Gefahr der Selbstentzündungen auszuschalten, wird erfindungsgemäß vorgeschlagen, eine Meßeinrichtung zu verwenden, die mit einer Luftklappe in Verbindung steht, d.h. im Moment der sich bildenden verstopfenden Drücke wird im Zyklon-Tiefsten im Bereich des Auslaufs eine klappe, abhängig von der @eßeinrichtung, geöffnet, und Luft aus der Atmosphäre wird in di unter Unterdruck stehende Zyklon-Anlage eingesaugt, wodurch die Brückenbildung pneumatisch durch den Ansaugstra## eingerissen wird.To these disadvantages of constant rartlmg and the danger of spontaneous combustion switch off, it is proposed according to the invention to use a measuring device, which is in connection with an air damper, i.e. at the moment of the forming clogging pressures in the cyclone lowest in the area of the outlet a flap, depending on the @ eating facility, opened, and air from the atmosphere is in di Cyclone system under vacuum is sucked in, making the bridging pneumatic is torn through the intake duct ##.

In der beiliegenden Zeichnung ist eine solche Anordnung dargestellt: mit 1 der Zyklon, nit 2 ein Ultraschall-Meßgerät, mit 3 eine Luftklappe mit automatischer Steuerung in Abhängigkeit vom Meßgerät, Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Verstopfungen in Zyklonausläufen dadurch zu beseitigen, daß eine Meßeinrichtung die Verstopferbildung anzeigt und gleichzeitig einen Vorgang einleitet, c'er vorzugsweise über eine Luftklappe die Möglichkeit gibt, @alschluft aus der Atmospäre in den unter Unterdruck stehenden Zyklon im Bereich der Verstopferbildung einfließen zu lassen und vorzugsweise ein optisches und oder akustisches Warnsignal auszulösen, der dem Wartungsstand der Gesamtanlage gegeben wird, sodaß eine Zentralwartung insbesondere bei Großanlagen durch Fernanzeige gegeben ist.Such an arrangement is shown in the accompanying drawing: with 1 the cyclone, with 2 an ultrasonic measuring device, with 3 an air flap with automatic Control as a function of the measuring device. The invention is not a matter of course to the forms of training shown and described in detail above but numerous modifications are possible without, however, from the To deviate from the basic idea, to remove blockages in cyclone outlets by that a measuring device indicates the clogging and at the same time a process initiates, c'er preferably gives the opportunity to @alschluft via an air flap from the atmosphere into the underpressure cyclone in the area of the blockage formation to flow in and preferably an optical and / or acoustic warning signal to trigger, which is given to the maintenance status of the entire system, so that a central maintenance is given by remote display, especially in large systems.
