Description

Sicherheitsabsperrvorrichtung für Ölfeuerungsanlagen. Ein Haupterfordernis zur Vermeidung von Störungen bei ölfeuerungsanlagen besteht darin, dem Ölbrenner nur dann Öl zuzuführen, wenn die zur Zerstäubung und Verbrennung notwendige Luft vorhanden ist, da andernfalls leicht Explosionen eintreten.Safety shut-off device for oil firing systems. A main requirement to avoid malfunctions in oil firing systems is to use the oil burner only to supply oil if the air required for atomization and combustion is present, otherwise explosions can easily occur.

Es sind Vorrichtungen bekannt geworden, bei denen eine Abhängigkeit der Ölzufuhr von der Luftzufuhr dadurch erreicht werden soll, daß Schwankungen in der Druckluftleitung mittels Membranen, Kolben oder Klappen eine Absperrung der Brennstoffleitung herbeiführen sollen. Bei neueren Ölfeuerungen beträgt aber die Pressung der zugeführten Zerstäubungsluft nur noch 5o bis ioo mm WS. Der für die Betätigung der vorgenannten Verblockungen verfügbare Luftdruck ist also sehr gering, so daß solche Vorrichtungen häufig durch Festbrennen und Festklemmen versagen. Dies ist besonders dann der Fall, wenn derartig empfindliche Vorrichtungen in engen Räumen unmittelbar neben der Feuerung angeordnet werden müssen. -Die Erfindung richtet sich auf ein Sicherheitsabsperrventil in der Olzuführungsleitung solcher Anlagen, bei denen der Zerstäubungslufterzeuger elektrisch angetrieben wird. Die Absperrung der Brennstoffleitung wird nach der Erfindung bei ausbleibender Druckluft durch den Kraftstrom des Drucklufterzeugers selbsttätig ausgelöst. Ebenso ist ein Öffnen der Brennstoffleitung nur dann möglich, nachdem der Drucklufterzeuger in Betrieb gesetzt ist.Devices have become known in which there is a dependency the oil supply from the air supply is to be achieved in that fluctuations in the compressed air line by means of membranes, pistons or flaps, a shut-off of the Should bring about fuel line. In the case of newer oil firing systems, however, this is Compression of the supplied atomizing air now only 50 to 100 mm WS. The one for them Actuation of the aforementioned blockages available air pressure is very low, so that such devices often burn and jam fail. this is especially the case when such sensitive devices are in tight spaces must be arranged immediately next to the furnace. -The invention is aimed on a safety shut-off valve in the oil supply line of such systems, in which the atomizing air generator is electrically driven. The barrier the fuel line is according to the invention in the absence of compressed air the power flow of the compressed air generator triggered automatically. There is also an opening the fuel line is only possible after the compressed air generator is in operation is set.

Die Zeichnung gibt ein Ausführungsbeispiel der Vorrichtung wieder.The drawing shows an embodiment of the device.

Abb. i zeigt einen Schnitt durch die Sicherheitsvorrichtung bei geöffneter Brennstoffleitung.Fig. I shows a section through the safety device when it is open Fuel line.

Abb. a zeigt einen Schnitt durch die Vorrichtung bei geschlossener Brennstoffleitung. Der Brennstoff tritt, vom Brennstoffvorratsbehälter kommend, durch das Rohr a in das Absperrventil b ein, um durch die Rohrleitung c dem Ölbrenner zuzufließen. Während des Betriebes wird die durch die Feder d belastete Ventilspindel e mittels des Hebels f, der Sperrklinke g und des Elektromagneten h in geöffneter Stellung gehalten. Der Elektroinagnet h ist mit dem Stromkreis des den Drucklufterzeuger antreibenden Elektromotors parallel geschaltet und bleibt, solange der Elektromotor läuft, also das Gebläse Zerstäubungsluft fördert, erregt.Fig. A shows a section through the device with the closed Fuel line. The fuel comes from the fuel storage tank, through the pipe a into the shut-off valve b to the oil burner through the pipe c to flow in. During operation, the valve spindle loaded by the spring d e by means of the lever f, the pawl g and the electromagnet h in open Position held. The electromagnet h is connected to the circuit of the compressed air generator driving electric motor connected in parallel and remains as long as the electric motor runs, so the fan promotes atomizing air, excited.

Wird nun der Gebläsemotor abgeschaltet oder bleibt aus irgendeiner Ursache der Kraftstrom aus, so wird im gleichen Augenblick der Elektromagnet h stromlos. Die Sperrklinke g gibt den Hebel f frei, der durch die Kraft der Feder d unter der Klinke g weggezogen wird. Darauf drückt die Feder d die Ventilspindel e auf den Sitz des Ventils b und sperrt die Brennstoffzufuhr zum Ölbrenner ab.If the fan motor is now switched off or if the power current fails for any reason, the electromagnet h is de-energized at the same moment. The pawl g releases the lever f, which is pulled away from under the pawl g by the force of the spring d. The spring d then presses the valve spindle e onto the seat of the valve b and shuts off the fuel supply to the oil burner.

Soll die ölfeuerungsanlage darauf wieder in Betrieb genommen werden, so muß zunächst der Gebläsemotor eingeschaltet werden. Der Magnet h wird dadurch gleichzeitig erregt und zieht die Sperrklinke g an.If the oil firing system is then to be put back into operation, the fan motor must first be switched on. The magnet h is thereby at the same time energizes and pulls the pawl g.

Erst jetzt bleibt beim Einrücken der Hebel f in der eingeklinkten Stellung stehen. Durch Anordnung einiger Kontakte kann man die beschriebene Sicherheitsabsperrvorrichtung leicht mit einer Alarmeinrichtung verbinden, durch welche eine unbeabsichtigte Stillsetzung der ölfeuerungsanlage dem @Bedienungspersonal mitgeteilt wird.Only now does the lever f remain in the latched position when it is engaged Standing position. The safety shut-off device described can be set up by arranging a few contacts easily connect to an alarm device, through which an unintentional shutdown of the oil firing system is communicated to the @operating staff.
