Abstract

The gas-impeller or expeller's motor is mounted in a double-wall housing rising up above the level of the liquid surface and open at the top. The height of the housing conforms to the required immersion depth for the impeller or expeller stirrer. The shaft outlet from the housing is sealed by elements opposite the fluid.

Description

Motoraggregat für Flüssigkeitsbegaser Zur Be- oder Entgasung von Flüssigkeiten ist es bekannt, Luft oder ein anderes gasförmiges Medium über rotierende Hohlkörper in die Flüssigkeit einzubringen, wobei das die Rotation bewirkende Motoraggregat über dem Flüssigkeitsspiegel angeordnet ist. Bei dieser allgemein gebräuchlichen konstruktiven Gestaltung ist eine verhältnismäßig lange Welle, die meist hohl ausgebildet ist und den Rotationskörper bewegt, erforderlich, sodaß eine zusätzliche Lagerung der Welle notwendig wird. Dies bedingt aber, auch wegen der weiteren Abdichtungsstelle gegenüber der Flüssigkeit, einen vermehrten Aufwand sowohl von der konstruktiven als auch von der wirtschaftlichen Seite, wodurch die Gesamtkosten eines solchen Antriebes nicht unerheblich vermehrt werden. Bei Einsatz von flüssigkeitsdichten, verkapselten Motoren ist es zwar möglich, eine kürzere, nicht zusätzlich zu lagernde Welle zum Antrieb des Rotations'körpers zu verwenden, Jedoch sind solche eingetauchte Motoraggregate kostenmäßig ebenfalls aufwendig, wozu noch die besondere Betriebsüberwachung und die schwieriger auszuführenden Reparaturen bei Störungen hinzukommen. Motor unit for liquid gasifiers For gassing or degassing of It is known for liquids, air or another gaseous medium via rotating Bringing hollow bodies into the liquid, with the motor unit causing the rotation is arranged above the liquid level. In this common one structural design is a relatively long shaft, which is usually hollow is and moves the rotary body, required, so that an additional storage the wave becomes necessary. But this is necessary, also because of the additional sealing point compared to the liquid, an increased effort both from the constructive as well as from the economic side, reducing the total cost of such Drive can be increased not insignificantly. When using liquid-tight, encapsulated motors, it is possible to have a shorter one that cannot be additionally stored Shaft to drive of the rotation body to be used, however Such submerged engine units are also expensive, including the special operational monitoring and the more difficult repairs to be carried out Disturbances are added.

Diese Probleme sind Jedoch gerade bei Vorrichtungen zur Be- und Entgasung von Flüssigkeiten, beispielsweise bei der Entsäuerung von Trink- und Nutzwasser, die mit in Flüssigkeiten eintauchenden Rotationskörpern arbeiten, sehr wesentlich, weil das Antriebsaggregat sowohl als Konstruktionselement als auch als Kastenteil eine bedeutende Rolle spielt. However, these problems are precisely the case with devices for gassing and degassing of liquids, for example in the deacidification of drinking and industrial water, who work with bodies of revolution immersed in liquids, very essential, because the drive unit is both a structural element and a box part plays an important role.

Den Gegenstand der Erfindung bildet ein unverkapseltes Motoraggregat als Antrieb von in Flüssigkeiten rotierenden, auf kurzer Motorwelle sitzenden Be- oder Entgasungsrührern. Das Motoraggregat ist dabei innerhalb eines doppelwandigen Behälters angeordnetg dessen Außenwand über den Flüssigkeitsspiegel hinausragt, wobei dieser Behälter nach oben offen ist. Die Höhe der Behälterwände ist dabei auf die erforderliche Eintauchtiefe abgestimmt, und es ist lediglich der Wellenaustritt aus dem Motorgehäuse gegenüber der Flüssigkeit abzudichten. The subject of the invention is an unencapsulated motor unit as a drive for loads rotating in liquids and sitting on a short motor shaft or degassing stirrers. The motor unit is inside a double-walled The container is arranged whose outer wall protrudes above the liquid level, this container is open at the top. The height of the container walls is included matched to the required immersion depth, and it is only the shaft exit to seal from the motor housing against the liquid.

Das in die Flüssigkeit einzubringende Gas wird dabei entweder vom Be- oder Entgasungsrührer selbst über Zuleitungen innerhalb des Behälters, die mit dem Rührer in Verbindung stehen, angesaugt, oder es wird mittels eines Gebläses über den gleichen Zuleitungaweg mit Ueberdruck eingeleitet. In beiden Fällen wird das Gas so geführt, daß damit auch der Motor eine Kühlung erfährt, wobei der vorhandene Motorventilator flir einen ausreichenden Wäniietausch sorgt. The gas to be introduced into the liquid is either from Gas or degassing stirrer itself via supply lines within the container, which with the stirrer in connection, sucked, or it is by means of a fan via the same supply route with overpressure initiated. In both Cases, the gas is guided in such a way that the engine is also cooled, with the existing motor fan ensures sufficient heat exchange.

In der Zeichnung wird das erfindungsgemäße Motoraggregat an einem Ausführungsbeispiel näher erläuterte Im doppelwandigen Behälter 1, der über den Flüssigkeitsspiegel hinausragt, befindet sich der Motor 2, der auf den Stützelementen 3 angeflanscht ist. Die Innenwand 4 des Behälters dient zur Abschirmung des Motors gegenüber der Flüssigkeit bei Stillstand des Antriebs und bildet gleichzeitig den ringförmigen Hohlraum, durch den das gasförmige Medium, beispielsweise Luft, dem Be- oder Iiitgasungsrührer im Betriebszustand zuströmt. Die relativ kurze Welle 5 trägt den Be- oder iitgasungsr(ihrer 6, wobei lediglich zwischen Welle und Motor eine Dichtung, und zwar durch das Element 7, erforderlich ist. In the drawing, the engine assembly according to the invention is on a Embodiment explained in more detail In the double-walled container 1, which over the If the liquid level protrudes, the motor 2 is located on the support elements 3 is flanged. The inner wall 4 of the container serves to shield the motor compared to the liquid when the drive is at a standstill and at the same time forms the annular cavity through which the gaseous medium, such as air, the Gassing or gassing stirrer flows in in the operating state. The relatively short wave 5 carries the gassing or gassing (their 6, with only between the shaft and the motor a seal, through the element 7, is required.

Im Betriebszustand, d.h. bei Rotation des Rührers, wird, falls Luft in die Flüssigkeit eingebracht werden soll, diese durch den gegebenen Sog über die ringförmige Hohlleitung 8 angesaugt und strömt sodann über den Tragkörper 9 des Rührers 6 durch die Auslässe 10 in die Flüssigkeit ein. In the operating state, i.e. when the stirrer rotates, if air is to be introduced into the liquid, this by the given suction over the sucked annular hollow pipe 8 and then flows over the support body 9 of the Stirrer 6 through the outlets 10 into the liquid.

Bei Verwendung eines Gebläses wird das Jeweilige Gas oder die Luft über den gleichen Zuleitungeweg in die Flüssigkeit eingedrückt.When using a blower, the respective gas or air pressed into the liquid via the same feed line.
