Description
Echoloteinrichtung zur Bunkerstandsmessung Zur Erfassung des Bunkerstandes in geschlossenen Bunkern, Behältern, Silos usw. werden häufig Echoloteinrichtungen mit Schallgeber und Schallempfänger verwendet. Diese Echolote benötigen für die Erfassung des Bunkerstandes keinerlei mechanische Erfassungsglieder, wie z. B. Schwimmer, Fühler od. dgl., und sind damit von deren mechanischen Mängeln frei.Echo sounder device for bunker level measurement For recording the level of the bunker echo sounder devices are often used in closed bunkers, containers, silos, etc. used with sounder and sound receiver. These echosounders need for that Detection of the bunker level no mechanical detection elements such. B. swimmers, Feelers or the like, and are thus free from their mechanical defects.
Geber und Empfänger von derartigen Echoloteinrichtungen sind in dem Bunker oder außerhalb des Bunkers angeordnet, dessen Füllungsgrad überwacht werden soll. In beiden Fällen sind Geber und Empfänger Störgeräuschen ausgesetzt, die von den verschiedensten Schallquellen, beispielsweise von dem Schüttguteinlauf in einen Kohlebunker, ausgehen. Encoder and receiver of such echo sounder devices are in the Bunker or arranged outside the bunker, the filling level of which is monitored target. In both cases, the transmitter and receiver are exposed to background noise from the most varied of sound sources, for example from the bulk material inlet into one Coal bunker, go out.
Diese Störgeräusche werden vom Schall empfänger mit den Schallechos aufgenommen und können zu Fehlmessungen führen.These background noises are emitted by the sound receiver with the sound echoes recorded and can lead to incorrect measurements.
Die Erfindung betrifft eine Echoloteinrichtung zur Bunkerstandsmessung in geschlossenen Bunkern oder Behältern mit einem Schallgeber und einem Schallempfänger zur Aufnahme des von dem zu erfassenden Material reflektierten Schallechos, bei der der Schallempfänger in einem besonderen, auf eine Durchtrittsöffnung des Bunkers aufgesetzten Gehäuse untergebracht ist. Zur Vermeidung der dargelegten Nachteile der bekannten Einrichtungen ist gemäß der Erfindung der Schallempfänger zur Verringerung des Einflusses von im Bunker vorhandenen Störschallquellen so weit von der Durchtrittsöffnung entfernt angeordnet, daß keine geradlinige Verbindung zwischen Schallempfänger und Störschallquellen vorhanden ist. Durch diese Anordnung wird der Einfluß von im Bunker vorhandenen Störschallquellen erheblich vermindert. Vorteilhafterweise ist das Empfängergehäuse zusätzlich mit Schall absorbierenden Schichten ausgekleidet. The invention relates to an echo sounder device for measuring bunker levels in closed bunkers or containers with a sounder and a sound receiver for recording the sound echo reflected by the material to be detected that of the sound receiver in a special, on a passage opening of the bunker mounted housing is housed. To avoid the disadvantages outlined of the known devices is according to the invention the sound receiver for reduction the influence of noise sources in the bunker so far from the passage opening located away that no straight connection between the sound receiver and Noise sources are present. This arrangement reduces the influence of in the bunker existing noise sources are significantly reduced. The receiver housing is advantageous additionally lined with sound-absorbing layers.
Zur näheren Erläuterung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel der neuen Echoloteinrichtung schematisch dargestellt ist. Ein Bunker 1 enthält eine Zulauföffnung 2 und eine Austrittsöffnung 3 für das gebunkerte Material 4. Oberhalb der Bunkerabdeckung befinden sich über einer Durchtrittsöffnung 8 in einem eigenen Empfängergehäuse 7 der Schallempfänger 5 und ein Schallgeber 6, die vornehmlich elektrisch arbeiten. Der Verlauf des vom Schallgeber ausgesandten und zum Schallempfänger reflektierten Schalles ist durch die Pfeile der gestrichelten Linie 9 angedeutet. For a more detailed explanation, reference is made to the drawing in which an embodiment of the new echo sounder device is shown schematically. A bunker 1 contains an inlet opening 2 and an outlet opening 3 for the bunkered Material 4. Above the bunker cover there is a passage opening 8 in a separate receiver housing 7 of the sound receiver 5 and a sounder 6, which mainly work electrically. The course of the emitted by the sounder and the sound reflected to the sound receiver is indicated by the arrows of the dashed line Line 9 indicated.
Im Ausführungsbeispiel wurde als Störschallquelle der »Gipfel« des gebunkerten Materials 4 angesehen, der durch den Aufprall von insbesondere stückigem Gut, wie z. B. Steinkohle, die stärksten Geräusche erzeugt. Schallempfänger 5, Schalldurchtrittsöffnung 8 und der Gipfel 10 des gebunkerten Materials liegen nicht auf einer geraden Linie, so daß direkter Störschalleinfluß auf den Schallempfänger 5 nicht möglich ist. In the exemplary embodiment, the "peak" of the viewed bunkered material 4, the particular by the impact of lumpy Good, such as B. coal, which produces the strongest noises. Sound receiver 5, sound passage opening 8 and the top 10 of the bunkered material are not in a straight line, so that direct interference noise influence on the sound receiver 5 is not possible.
Um auch eine indirekte Störschallbeeinflussung des Schallempfängers 5 durch von der Gehäusewand des Empfängergehäuses 7 reflektierten Schall zu vermeiden, ist das Empfängergehäuse innen in an sich bekannter Weise mit Absorptionsschichten, z. B. There is also an indirect noise influence on the sound receiver 5 to avoid sound reflected from the housing wall of the receiver housing 7, is the receiver housing inside in a known manner with absorption layers, z. B.
Schaumstoff, zur Aufnahme solcher Störgeräusche ausgekleidet.Foam lined to absorb such noise.
Eine weitere Vervollkommnung der neuen Echoloteinrichtung läßt sich durch Anwendung der an sich bekannten Gießharztechnik erzielen. Da Schallgeber und Schallempfänger mit elektrischen Schaltungselementen arbeiten, wird durch ihre Einbettung in Gießharz ein besonderer Schutz gegen Korrosion und eine für den rauhen Bunkerbereich geeignete robuste Ausführungsform erzielt. A further improvement of the new echo sounder device can be achieve by using the known casting resin technique. Since sounder and Sound receivers work with electrical circuit elements by embedding them in cast resin a special protection against corrosion and one for the rough bunker area suitable robust embodiment achieved.
