Description
Die Neuerung betrifft eine Einrichtung zur Beobachtung des Füllstandes von Vorratslagern für Holz-Pellets, welche in ehemalige Heizöltanks eingebaut sind.The innovation relates to a device for monitoring the level of storage bins for wood pellets, which are installed in former fuel oil tanks.
Im Zuge der Förderung und des Ausbaues der Verwendung regenerativer Rohstoffe hat die Verwendung von Holz-Pellets für Heizzwecke in den letzten Jahren viel an Bedeutung hinzugewonnen. Üblicherweise werden die Pellets in leicht einsehbaren und leicht zugänglichen Räumen innerhalb des zu heizenden Gebäudes gelagert. Oft ist aber in Altbauten ein solcher Raum nicht verfügbar, wenn zu Beispiel eine Ölheizung erneuert werden soll. Dies ist z. B. der Fall, wenn der Heizöl-Tank sich nicht im Haus befindet, weil ein Erd-Tank außerhalb des Gebäudes vorgesehen wurde.In the promotion and expansion of the use of renewable raw materials, the use of wood pellets for heating has gained much in importance in recent years. Usually, the pellets are stored in easily visible and easily accessible spaces within the building to be heated. Often, however, such a room is not available in old buildings, if, for example, an oil heater is to be renewed. This is z. As is the case when the fuel oil tank is not in the house, because an earth tank was provided outside the building.
Typischerweise eignen sich ehemalige liegende Heizöl-Tanks mit einem ehemaligen Speichervolumen von 10 000 bis 20 000 Litern Heizöl für den Einbau eines Lagers für Holz-Pellets besonders. Die Pellets können in diesem Fall allerdings nicht mechanisch zum Heizkessel befördert werden, sondern werden über einen Schlauch angesaugt, weil der einzige Zugang zum Pellet-Lager nur über den Domschacht des ehemaligen Heizöl-Tanks möglich ist. Über den Deckel des Domschachtes muss auch der Schlauch zum Schließen des Luftkreislaufes der Ansaugeinrichtung geführt werden.Typically, former lying fuel oil tanks with a former storage volume of 10 000 to 20 000 liters of fuel oil are particularly suitable for the installation of a warehouse for wood pellets. However, the pellets can not be transported mechanically to the boiler in this case, but are sucked in via a hose, because the only access to the pellet store is only possible via the dome shaft of the former fuel oil tank. The hose for closing the air circuit of the suction device must also be routed via the cover of the dome shaft.
Typischerweise besteht der Teil der Ansaugeinrichtung im ehemaligen liegenden Heizöl-Tank aus in Reihe angeordneten Vorrichtungen, welche nach ihrer oberflächlichen Ähnlichkeit mit einem allgemein bekannten asiatischen Kochgeschirr als „Woks” bezeichnet werden. In der
Das zu lösende Problem entsteht nun dadurch, dass durch die unregelmäßige Oberfläche der Pellets im Tank herkömmliche auf eine ebene Oberfläche des Füllgutes angewiesene Füllstandsmess-Methoden nicht anwendbar sind. In der
Erfindungsgemäß wird das Problem gelöst, indem im Domschacht eine Einrichtung zur Beobachtung des Füllstandes angeordnet wird, welche dadurch gekennzeichnet ist, dass in einem durch eine durchsichtige Scheibe
Die Ebene, in welcher der Flachstrahl liegt, bildet einen definierten Winkel mit der Außenfläche der ebenen Scheibe in einer Weise, dass sich der Flachstrahl in Abströmrichtung verbreitert, sich die zentrale Achse der Flachstrahl-Düse mit der optischen Achse der Kamera näherungsweise schneidet und der Flachstrahl symmetrisch zur zentralen Achse der Flachstrahl-Düse und symmetrisch zum Gehäuse auffächert.The plane in which the flat jet lies forms a defined angle with the outer surface of the flat disc in such a way that the flat jet widened in the outflow direction, the central axis of the flat jet nozzle approximately intersects with the optical axis of the camera and the flat jet fanned symmetrically to the central axis of the flat jet nozzle and symmetrical to the housing.
Außerdem trifft die Ebene, in welcher der Flachstrahl liegt so auf die Scheibe, dass das Leuchtfeld der Lichtquelle und das Sichtfeld der Kamera vom gasförmigen Medium überströmt wird bevor es von der Scheibe abströmt.In addition, the plane in which the flat jet lies on the disk so that the light field of the light source and the field of view of the camera is covered by the gaseous medium before it flows from the disc.
