Abstract

The burner regulation system has the temperature of the material within the drying drum detected directly at a given position and used for accurate temperature regulation. The temperature is detected by a temperature sensor enclosed by a protective sleeve and fitted directly into the drying drum for detecting the temperature of the mineral curtain.

Description

Es ist bekannt, daß für die Regelung der Energiezufuhr bei Trockentrommeln die Eingangsgrößen Materialmenge, Feuchtigkeit, Abgastemperatur und Mineralauslauftemperatur die Basisgrößen sind. Ziel bei der Regelung ist es, daß der gewünschte Temperaturwert am Mineralauslauf schnell erreicht und über die unterschiedlichsten Betriebsphasen konstant gehalten wird.It is known that the input variables for regulating the energy supply in dry drums Material quantity, moisture, exhaust gas temperature and mineral outlet temperature are the basic parameters. The aim of the control is that the desired temperature value is quickly reached at the mineral outlet and is kept constant over the most varied operating phases.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, daß mit, dem herkömmlichen Systemaufbau bedingt durch die langen Verzugszeiten (zwischen Änderung Energiezufuhr und Reaktion Mineralauslauftemperatur) in der Trockentrommel keine zufrieden­ stellende Regelung erreicht wird.The invention specified in the claim is based on the problem that with conventional system structure due to the long delay times (between changes Energy supply and reaction mineral outlet temperature) in the drying drum not satisfied regulating regulation is reached.

Weiterhin liegt das Problem zugrunde, daß ein Temperatursensor auf Grund der rauhen Umgebung in der Trockentrommel schnell verschleißt bzw. durch den Einfluß des Abgases und Mineralbewegung keine realistischen Temperaturwerte liefert und keine Regelung damit möglich ist.Furthermore, there is the problem that a temperature sensor due to the harsh environment in the drying drum wears out quickly or due to the influence of the exhaust gas and mineral movement provides no realistic temperature values and no regulation is possible with it.

Dieses Problem wird durch die im Patentanspruch aufgeführten Merkmale gelöst.This problem is solved by the features listed in the claim.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch die Temperaturerfassung direkt in der Trockentrommel die Verzugszeiten stark reduziert werden da bei Änderung der Energiezufuhr sich die Trockentrommelinnentemperatur sehr schnell mit angleicht. The advantages achieved by the invention are in particular that The delay times can be greatly reduced by measuring the temperature directly in the drying drum since when the energy supply changes, the inside temperature of the drying drum changes very quickly equalizes.  

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below described.

Bei dieser Trockentrommel wurde die Plazierung der Meßstelle in der vorletzten Wurfschaufelreihe vor dem Flammenraum vorgenommen, da hier das Mineral die Wasserverdampfungsphase überwunden hat. (ermittelt durch meßtechnische Probeuntersuchungen)With this drying drum, the placement of the measuring point in the penultimate row of throwing blades was made the flame space, since here the mineral overcomes the water evaporation phase Has. (determined by metrological test examinations)

Wie im Detail zu sehen (Fig. 2) besteht die Schutzeinbaute aus zwei Kammern und die Geometrie ist so gestaltet, daß der Sensor bei jeder Phase der Umdrehung mit Mineral umhüllt ist. Durchläuft die Einbaute den unteren Bereich der Trockentrommel, wird das Mineral in der Schutzeinbaute komplett ausgetauscht, so daß eine reale Messung möglich ist.As can be seen in detail ( Fig. 2), the protective installation consists of two chambers and the geometry is designed in such a way that the sensor is coated with mineral at every phase of the rotation. If the installation passes through the lower area of the drying drum, the mineral in the protective installation is completely replaced, so that a real measurement is possible.
