Description
Beschreibung,Description,
Die Erfindung bezieht sich auf ein Durchlaufmeßgerät zum kontinuierlichen Wägen von Schüttgütern.The invention relates to a flow measuring device for the continuous weighing of bulk materials.
Bekannt sind Durchlaufmeßgeräte, bei denen die Reaktionskraft beim Umlenken des Schüttgutstromes zur Gewichtsermittlung ausgewertet wird.Flow measuring devices are known in which the reaction force when the bulk material flow is diverted is evaluated to determine the weight.
Bei den bekannten Ausführungen sind in Förderschächten Pralloder Umlenkplatten zur Umlenkung des durchlaufenden Schüttgutstromes angeordnet. Diese Prall- oder Umlenkplatten sind über Gestänge mit den außerhalb der Förderschächte liegenden Meßwertaufnehmern verbunden.In the known designs, impact or deflection plates are arranged in conveyor shafts to deflect the flow of bulk material. These impact or deflection plates are connected to the measuring sensors located outside the conveyor shafts via rods.
Gegen Staubaustritt müssen die Wandöffnungen in den Förderschächten zur Duchführung der Gestänge abgedichtet werden. Da die zur Gwichtsermittlung dienende Reaktionskraft verhältnismäßig gering ist, wird die Meßgenauigkeit durch die in den Dichtungen auftretenden Kräfte gemindert.The wall openings in the conveyor shafts for the rods to pass through must be sealed to prevent dust from escaping. Since the reaction force used to determine the weight is relatively low, the measuring accuracy is reduced by the forces occurring in the seals.
Bei dem nachstehend beschriebenen Erfindungsgegenstand ist der Meßwertaufnehmer unmittelbar an der Prall- oderUmlenkplatte im Förderschacht angeordnet womit die obigen Nachteile vermieden sind.In the invention described below, the measuring sensor is arranged directly on the impact or deflection plate in the conveyor shaft, thus avoiding the above disadvantages.
Die Erfindung wird anhand der Zeichnungen Fig.l bis 3 beschrieben.The invention is described with reference to the drawings Fig. 1 to 3.
Fig.l. Hier wird schematisch die Funktion des Erfindungsgegenstandes dargestellt. Durch den geneigten Einfüllschacht 1 wird das Schüttgut gegen die Prall- oder Umlenkplatte 2 gelenkt.Die beim Umlenken des Schüttgutstromes an der Prallplatte auftretende Reaktionskraft wird am Meßwertaufnehmer 3 ermittelt.Die Prallplatte mit Meßwertaunehmer sind im Förderschachtgehäuse 4. angeordnet. Dabei ist der Meßwertumformer durch ein Konsol 4.1 fest mit dem Gehäuse 4 verbunden.Fig.l. The function of the subject matter of the invention is shown schematically here. The bulk material is directed against the impact or deflection plate 2 by the inclined filling shaft 1. The reaction force that occurs on the impact plate when the bulk material flow is deflected is determined on the measuring sensor 3. The impact plate with the measuring sensor are arranged in the conveyor shaft housing 4. The measuring transducer is firmly connected to the housing 4 by a bracket 4.1.

Fig.2 Schematisch ist hier die Prallplatte mit dem Meßwertaufnehmer in der Seitenansicht dargestellt Die Prallplatte hängt mit der Traverse 2.1 an 4 Lenkern 5.1 bis 5.4 an der festen Konsole 4. Vorzugsweise bestehen die Lenker 5.1 bis 5.4 aus Blattfedern die je nach Leistungsanforderung der Vorrichtung in den Mittelabschnitten verstärkt sind. Durch die Anordnung der Lenker wird die Prallplatte in horizontaler Bewegungsrichtung geführt, wodurch nur die horizontal gerichteten Recktionskräfte auf den Meßwertaufnehmer 3 übertragen werden. Der Meßwertaunehmer 3 ist am Konsol 4 befestigt.Über den Steg 2.2 und die Überlastkupplung 6 wird die horizontale Reaktionskraft auf den Meßwertaufnehmer 3 übertragen.Bei auftretender Überlast wird die horizontale Bewegung der Prallplatte durch den Anschlag 4.1 begrenzt.Fig.2 The impact plate with the sensor is shown schematically here in a side view. The impact plate hangs with the cross member 2.1 on 4 links 5.1 to 5.4 on the fixed bracket 4. The links 5.1 to 5.4 preferably consist of leaf springs which are reinforced in the middle sections depending on the performance requirements of the device. The arrangement of the links guides the impact plate in a horizontal direction of movement, whereby only the horizontally directed reactive forces are transferred to the sensor 3. The sensor 3 is attached to the bracket 4. The horizontal reaction force is transferred to the sensor 3 via the web 2.2 and the overload coupling 6. If an overload occurs, the horizontal movement of the impact plate is limited by the stop 4.1.
Fig.3 In der Ansicht "A" sind hier die Lenker 5.3 und dargestellt.Die Prallplatten müssen Verwindungsfest parallel geführt werden. Bei gößeren Durchlaufmeßgeräten mit hohen Leistungsanforderungen werden daher 2 Lenker durch eine Quertraverse 5.5 verdrehfest verbunden.Fig.3 In view "A" the links 5.3 and are shown here. The impact plates must be guided parallel and torsion-proof. For larger flow meters with high performance requirements, 2 links are therefore connected torsion-proof by a cross-member 5.5.
