Optischer Verschluß zum Überprüfen der Wirksamkeit von Flammen-DetektorenOptical shutter for checking the effectiveness of flame detectors

(Zusatz zum Hauptpatent, Patentanmeldung P 25 2j5 14-9.6)(Addition to the main patent, patent application P 25 2j5 14-9.6)

Das Hauptpätent betrifft einen Flammen-Detektorkopf mit einer Fotozelle und einem optischen Verschluß zwischen der Fotozele und der Strahlungs-Einbittsöffnung des Detektorkopfes, der zur Überprüfung der Wirksamkeit des Flammen-Detektors dient und zur Anwendung an Brennern von Heizkesseln und Öfen bestimmt ist. Der optische Verschluß gemäß dem Hauptpatent besteht aus einem wenigstens teilweise kugelförmigen, drehbar gelagerten Schließkörper mit einer durchgehenden Öffnung, einer dem Schließkörper vorgelagerten feststehenden Maske mit kreisrunder, öffnung, aus einer Vorrichtung zum Verdrehen des Schließkörpers sowie aus einer Einrichtung, mit de-/der Schließkörper in die Normal -The main patent concerns a flame detector head with a Photo cell and an optical shutter between the photo cell and the radiation inlet opening of the detector head, which is used to check the effectiveness of the flame detector and for use on burners in heating boilers and ovens. The optical shutter according to the main patent consists of an at least partially spherical, rotatably mounted closing body with a through opening, one in front of the closing body fixed mask with circular, opening, from one Device for rotating the closing body as well as from a device with de- / the closing body in the normal -

eine einseitige Lagerung des Drehzapfens des Sehließkörpers mittels eines Kugellagers vorgesehen.a one-sided mounting of the pivot of the closing body is provided by means of a ball bearing.

Um die Funktionssicherheit des optischen Verschlusses in Anbetracht der gegebenen Arbeitsbedingungen weiterhin zu verbessern, ist gemäß der Erfindung vorgesehen, den Schließkörper zweiseitig zu ü&ern, wobei in besonders vorteilhafter Weise eine Lagerung der beiden Drehzapfen in selbstschmierenden Gleitlagern vorgesehen ist, die sich fast über die ganze Länge der Drehzapfen erstrecken. In Weiterbildung dieser Gleitlagerung des Drehzapfens ist gemäß der Erfindung weiterhin vorgesehen, den Schließkörper als zylinderförmigen Körper auszubilden, wodurch sich neben der funktionssicheren Ausbildung auch eine fertigungsmäßig einfachere Ausbildung des Verschlusses ergibt.In order to keep the functional reliability of the optical shutter in view of the given working conditions improve, it is provided according to the invention to over & ern the closing body on two sides, in which case in particularly advantageous Way, a bearing of the two pivot pins in self-lubricating slide bearings is provided, which is almost Extend the full length of the pivot pins. In a further development of this sliding bearing of the pivot pin is according to the invention further provided to form the closing body as a cylindrical body, which is next to the functionally reliable training also results in a simpler production design of the closure.

In der Zeichnung ist der Verschluß gemäß der Erfindung dargestellt. Es zeigenIn the drawing, the closure according to the invention is shown. Show it

Fig. 1 den Verschluß im Längsschnitt,Fig. 1 the closure in longitudinal section,

Fig. 2 einen Schnitt längs der Linie A-A in Fig.Fig. 2 is a section along the line A-A in Fig.

Der Verschluß besteht im wesentlichen aus einem äußeren Gehäuse 1, einem inneren Gehäuse 2, das am äußeren Gehäuse befestigt ist, und einer Fotozelle J5. In dem inneren Gehäuse 2 sind Öffnungen K für Kühlluft vorgesehen. Im vorderen Teil des inneren Gehäuses 2 ist eine Quarzlinse 5 angebracht, hinter der ein Schließkörper 6 angeordnet ist, vor dem eine feststehende Maske 7 befestigt ist. Der Schließkörper 6 trägt eine Fahne 8, die von einer Druckluftdüse 9 beaufschlagt wird und an derThe shutter essentially consists of an outer housing 1, an inner housing 2, which is attached to the outer housing, and a photocell J5. In the inner housing 2 openings K are provided for cooling air. In the front part of the inner housing 2, a quartz lens 5 is attached, behind which a closing body 6 is arranged, in front of which a stationary mask 7 is attached. The closing body 6 carries a flag 8, which is acted upon by a compressed air nozzle 9 and on the

Die Verbesserung gemäß der vorliegenden Erfindung besteht gegenüber dem Hauptpatent in der doppelten bzw. zweiseitigen Lagerung des Schließkörpers 6 mittels zweier Drehzapfen, die in selbstschmierenden Gleitlagern gelagert sind, die sich fast über die ganze Länge der Drehofen erstrecken. Außerdem ist der Schließkörper zylindrisch statt kugelförmig ausgebildet.The improvement according to the present invention consists over the main patent in the double or two-sided Storage of the closing body 6 by means of two pivot pins, which are mounted in self-lubricating slide bearings are located almost over the entire length of the rotary kiln extend. In addition, the closing body is cylindrical instead of spherical.
