Description
Tauchturbinenrührer mit gleichzeitigem Wärmeaustausch Um empfindliches Gut, das zum Anlegen bzw. Anbrennen neigt, zu erhitzen, ist es nötig, Heizanlagen zu verwenden, bei denen die Wärmeübertragung über eine geeignete Flüssigkeit erfolgt. Trotz dieser Vorsicht läßt sich ein Anlegen oft nicht verhüten, so daß ein zusätzliches, intensives Rühren notwendig ist.Submersible turbine stirrer with simultaneous heat exchange Around sensitive items Good, which tends to apply or burn, to heat, it is necessary to have heating systems where the heat is transferred through a suitable liquid. In spite of this caution, it is often impossible to prevent it from being put on, so that an additional, intensive stirring is necessary.
Solch eine Anlage ist nicht nur teuer, sondern in manchen schwierigen Fällen auch unsicher.Such a plant is not only expensive, but in some cases difficult Cases also unsafe.
Es ist bereits zur Konstanthaltung der Temperatur von Bädern ein Tauchgerät als Thermostat bekannt, bei dem um ein zylindrisches Pumpenrohr, durch das hindurch die Flüssigkeit von einem mit einer Pumpe ausgestatteten Rührwerk hindurchgedrückt wird, ein Ringheizkörper gelegt ist. Dabei kann nur solche Flüssigkeit aus dem Auslaufstutzen des Pumpenrohres austreten, die dem intermittierend arbeitenden Heizkörper nicht unmittelbar ausgesetzt ist. Mit einer solchen Anordnung sind aber hitzeempfindliche Flüssigkeiten, also z. B. viskoseFlüssigkeiten oder Suspensionen empfindlicher Stoffe, überhaupt nicht oder nicht ohne Schädigung zu erhitzen, denn durch die bei Verwendung einer Pumpe als Langsamläufer hervorgerufene geringe Strömung an der Außenwand des Heizkörpers wird sich dieser stark erwärmen und zugleich eine örtliche Überhitzung der Flüssigkeit hervorrufen. Eine ähnliche Vorrichtung sieht die Anordnung eines großflächigen Heizkörpers oberhalb eines Rotationskörpers vor. Der Rotationskörper dient dabei mit seiner durchbrochenen Käfigmantelfläche zum Emulgieren flüssiger Gemenge. Durch die bei dieser bekannten Anordnung bedingte langsame Flüssigkeitsströmung am Heizkörper ist stets die Gefahr einer örtlichen Überhitzung der Flüssigkeit gegeben. It is already used to keep the temperature of baths constant Diving device known as a thermostat, in which around a cylindrical pump tube, through through which the liquid is pushed through by an agitator equipped with a pump a ring heater is placed. Only such liquid can come out of the outlet nozzle of the pump pipe, which the intermittently working radiator does not is immediately exposed. With such an arrangement, however, they are heat-sensitive Liquids, e.g. B. viscous liquids or suspensions of sensitive substances, not to heat at all or not without damage, because by using low flow caused by a pump running at low speed on the outer wall of the Radiator will heat up this strongly and at the same time a local overheating of the liquid. A similar device provides the arrangement of a large radiator above a rotating body. The solid of revolution With its perforated outer surface of the cage, it is used to emulsify liquids Mixture. Due to the slow flow of liquid caused by this known arrangement there is always a risk of local overheating of the liquid on the radiator.
Aus diesen bekannten Anordnungen geht aber nicht hervor, daß der Heizkörper im stärksten Saug- bzw. From these known arrangements it does not appear that the Radiator in the strongest suction resp.
Druckbereich anzuordnen ist, um bei Verwendung eines schnell laufenden, nach dem Turbinenprinzip arbeitenden Tauchrührers das Rührgut mit großer Geschwindigkeit am Heizkörper vorbeiziehen oder -drücken zu können, wodurch insbesondere empfindliche Flüssigkeiten oder Suspensionen gefahrlos er- hitzt werden. Weiterhin kann auf die gleiche Weise eine schnelle Kühlung des Rührgutes erreicht werden.Print area is to be arranged in order to be able to use a fast running, according to the turbine principle working immersion stirrer the material to be stirred at high speed to be able to pull or push past the radiator, which makes particularly sensitive Liquids or suspensions can be safely get heated. Furthermore, the In the same way, rapid cooling of the material to be stirred can be achieved.
Die Zeichnung (Abb. 1 und 2) zeigt die Anordnung des Heiz- bzw. Kühlkörpers 3 im stärksten Saug- 4 bzw. Druckbereich 5 der Rührturbine 2. Versuche haben ergeben, daß nicht nur schonendste Behandlung des Rührgutes gewährleistet ist, sondern auch noch eine bedeutend bessere Ausnutzung der Heiz- bzw. The drawing (Fig. 1 and 2) shows the arrangement of the heating and cooling elements 3 in the strongest suction 4 or pressure area 5 of the stirring turbine 2. Tests have shown that not only the gentlest handling of the material to be mixed is guaranteed, but also significantly better utilization of the heating or
Kühlenergie erreicht wird.Cooling energy is achieved.
