Description
Vorrichtung zum Dispergieren pulverförmiger Stoffe Es sind bereits Vorrichtungen zum Dispergieren pulverförmiger Stoffe, und zwar insbesondere solcher Stoffe, die, wie Kalkhydrat, beim Dispergieren zur Staubbildung neigen, bekannt, die aus einem zylindrischen oder nach unten konisch verlaufenden Gefäß bestehen, das mit einem tangentialen Einlaß für die Flüssigkeit ausgestattet ist und bei dem im oberen Ende ein Einlauftrichter für das pulverförmige Gut vorgesehen und am unteren Auslaß ein Behälter zur Aufnahme der Dispersion angeordnet ist. Diese Vorrichtungen schließen beim Betrieb nicht die Möglichkeit aus, daß Verkrustungen oder Verbackungen in der Vorrichtung auftreten, da der Mischungs- oder Dispersionsvorgang durch Berührung mit den Gehäusewandungen oder mit Einbauten erfolgt.Device for dispersing powdery substances There are already Devices for dispersing powdery substances, in particular such Substances, such as hydrated lime, tend to form dust when dispersed, known, which consist of a cylindrical or downwardly conical vessel, which is equipped with a tangential inlet for the liquid and in which an inlet funnel for the powdery material is provided in the upper end and at the lower end Outlet a container for receiving the dispersion is arranged. These devices do not exclude the possibility of incrustations or caking during operation occur in the device because the mixing or dispersing process occurs through touch takes place with the housing walls or with built-in components.
Die Verkrustungen erfordern, nachdem sie ein gewisses Ausmaß erreicht haben, eine Unterbrechung des Betriebes. Ein weiterer Nachteil besteht darin, daß bei stäubendem Gut der Dispersionsvorgang nicht unter völligem Staubabschluß stattfinden kann, da durch den offenen Auslauf des Dispersionsbehälters eine Staubbildung ermöglicht wird. Ein weiterer Nachteil dieser Vorrichtungen, die ohne Misch- oder Rührvorrichtungen betrieben werden, besteht darin, daß die Dispersion nicht immer mit der erwünschten Gleichmäßigkeit erzielt wird, da bei unterschiedlichenBetriebsverhältnissen, beispielsweise bei schwankender Flüssigkeitszufuhr, eine unvollständige Dispersion die Folge sein kann. The incrustations require after they have reached a certain extent have an interruption in operations. Another disadvantage is that In the case of dusting material, the dispersion process does not take place with complete exclusion of dust can, since the open outlet of the dispersion tank enables dust to form will. Another disadvantage of these devices, the lack of mixing or stirring devices are operated, is that the dispersion is not always with the desired Uniformity is achieved because at different operating conditions, for example If the fluid intake fluctuates, the result will be incomplete dispersion can.
Diese Nachteile werden bei einer Vorrichtung zum Dispergieren pulverförmiger Stoffe, insbesondere Kalkhydrat, bestehend aus einem zylindrischen oder nach unten konisch verlaufenden Gefäß mit einem tangentialen Einlaß für die Flüssigkeit, einem Einlauftrichter für das Gut am oberen Ende und einem unter dem unteren Auslaß angebrachten Behälter, vermieden, wenn erfindungsgemäß der obere Rand des oben offenen Behälters über den unteren Auslaß hinaufreicht, im unteren Teil des Gefäßes Rippen angebracht sind und im oberen Teil des Gefäßes oberhalb der Mündung des Einlauftrichters ein tangential mündender überlauf vorgesehen ist. These disadvantages become more powdery in a device for dispersing Substances, especially hydrated lime, consisting of a cylindrical or downward conical vessel with a tangential inlet for the liquid, a Inlet funnel for the material at the upper end and one under the lower outlet Container, avoided if, according to the invention, the upper edge of the container open at the top Reaching up over the lower outlet, ribs are attached in the lower part of the vessel and in the upper part of the vessel above the mouth of the inlet funnel tangentially opening overflow is provided.
Durch die erfindungsgemäße Ausbildung des als Wasserabschluß dienenden unteren Behälters wird ein staubfreier Betrieb gewährleistet. Durch die im unteren Teil des Dispersionsgefäßes angeordneten Leitrippen wird zufolge der durch sie bewirkten Richtungsänderung des Dispersionsstromes eine innige Vermischung und damit eine vollständige Dispersion erreicht, während durch den im oberen Teil des Dispersionsgefäßes angeordneten Überlauf ein Eintreten der Flüssigkeit in den Einlauftrichter und damit die Ursache zur Entstehung von Inkrustationen vermieden wird. The inventive design of the serving as a water seal Dust-free operation is guaranteed with the lower container. Through the in the lower Part of the dispersion vessel arranged guide ribs is due to the effect caused by them Change of direction of the dispersion stream an intimate mixing and thus a complete dispersion is achieved while through the in the upper part of the dispersion vessel arranged overflow an entry of the liquid into the inlet funnel and in order to the cause of the formation of incrustations is avoided.
Die Zeichnung zeigt einen Schnitt durch die erfindungsgemäße Vorrichtung. The drawing shows a section through the device according to the invention.
An dem Bunkerauslauf a ist ein trichterförmiger Auslaufb vorgesehen, der in einen Behälter c einmündet. Dieser Behälter c ist nach dem Bunkerauslauf völlig geschlossen. Dieser Behälter c ist beispielsweise nach unten konisch ausgebildet, kann jedoch auch zylindrisch oder anders ausgebidet werden. A funnel-shaped outlet b is provided at the bunker outlet a, which opens into a container c. This container c is after the bunker outlet completely closed. This container c is for example conical downwards, however, it can also be made cylindrical or otherwise.
Die Auslauföffnung des Behälters c mündet in einen Behälter g ein, dessen Überlaufkanten über dem Auslauf des Behälters c liegen. Der Behälter g ist mit Wasser gefüllt. The outlet opening of the container c opens into a container g, whose overflow edges are above the outlet of the container c. The container g is filled with water.
An den Behälter c ist ein tangential angeordnetes Rohr d angeschlossen. Durch dieses Rohr d wird Flüssigkeit zugeführt. Je nach der zuströmenden Wassermenge wird mehr oder weniger pulverförmiger Stoff aus dem Silo abgezogen. Durch die tangentiale Einführung der Flüssigkeit ergibt sich eine kreisende Benetzung der inneren Wände des Behälters c, so daß Ansätze sich nicht bilden können. A tangentially arranged pipe d is connected to the container c. Liquid is supplied through this pipe d. Depending on the amount of water flowing in more or less powdery substance is withdrawn from the silo. Through the tangential Introducing the liquid results in a circular wetting of the inner walls of the container c, so that approaches cannot form.
Um zu verhindern, daß bei zu starker Flüssigkeitszuführung die Flüssigkeit in den Silo eintreten kann, ist im oberen Teil des Behälters c ein tlberlaufrohr e vorgesehen. Dieses Überlaufrohr e dient auch gleichzeitig als Kontrollorgan für den Flüssigkeitszustrom. To prevent the liquid from becoming too strong if the liquid is supplied too much can enter the silo, there is an overflow pipe in the upper part of the container c e provided. This overflow pipe e also serves as a control element for the liquid inflow.
Am unteren Auslaufende des Behälters c sind längsgerichtete Radialrippen f vorgesehen, die den Zweck haben, die Kreisströmung der Flüssigkeit am Austritt zu behindern und eine innige Durchmischung der Flüssigkeit mit dem pulverförmigen Stoff zu gewährleisten. At the lower outlet end of the container c are longitudinal radial ribs f provided, which have the purpose of the circular flow of the liquid at the outlet to hinder and intimate mixing of the liquid with the powdery Ensure fabric.
