Description

Vorrichtung zur mechanischen Bearbeitung thixotroper Massen Zusatz zum Patent 625 I35 In dem Patent 625 I35 ist ein Verfahren zur mechanischen Bearbeitung thixotroper Massen beschrieben, welches dadurch gekennzeichnet ist, daß in die Massen rasch schwingende Nadeln oder Saiten eingebracht werden.Device for the mechanical processing of thixotropic masses additive to patent 625 I35 In the patent 625 I35 is a method for mechanical processing thixotropic masses described, which is characterized in that in the masses rapidly vibrating needles or strings are inserted.

In weiterer Ausbildung dieses Verfahrens wurde nun gefunden, daß man auch Verdüsungen von thlxotropen oder sich ähnlich verhaltenden Massen, wie Gelen, Filterpreßkuchen oder Nutschrückstände, unter Zuhilfenahme von gespannten Gasen oder auch bei kompressorlosem Pumpenverfahren mit besonderem Vorteil so vornehmen kann, daß im Innern des Flüssigkeitskanals der Düse eine oder mehrere gegebenenfalls profilierte Nadeln untergebracht werden, die durch elektromagnetische Vorrichtungen in rasche mechanische Schwingungen versetzt werden. In a further development of this process it has now been found that one also atomises thlxotropic or similarly behaving masses, such as Gels, filter press cake or nutsch residues, with the help of strained Perform gases or even with compressorless pumping processes with particular advantage in this way can that in the interior of the liquid channel of the nozzle one or more optionally profiled needles are housed by electromagnetic devices be set in rapid mechanical vibrations.

Wenn auch im kolloidchemischen Sinne echte Gele in den meisten praktischen Fällen schon beim Durchdrücken durch Kanäle Thixotropie zeigen und flüssig werden, so gelingt diese Maßnahme doch nicht bei den ebenfalls thixotropen heterogenen Massen, wie Filterpreßkuchen, Nutschrückständen oder ähnlich aufgebauten Fließkohlen usw. Diese sondern beim Drücken durch Kanäle, Spalte usw.Even if, in the colloid-chemical sense, real gels in the most practical Cases show thixotropy and become liquid when pushing through channels, so this measure does not succeed in the likewise thixotropic heterogeneous masses, such as filter press cake, nut residue or similarly structured fluid carbons, etc. These but when pressing through channels, columns, etc.

Trägerflüssigkeit ab und verstopfen dann die Kanäle. Das Beseitigen von solchen Absonderungen durch mehr oder weniger langsam schwingende Räum- oder Ventilnadeln, die verschiedentlich auch zur Beaufschlagung von Dieselmotoren mit schwer fließbaren Brennstoffen, wie Teer, vorgeschlagen wurden, hat mit der durchgreifenden Verflüssigung obengenannter Massen durch rasch schwingende Nadeln in Düsen und Kanälen nichts gemeinsam. Es wird vielmehr das im Hauptpatent unter Schutz genommene Phänomen einer durchgreifenden Verflüssigung gemäß vorliegender Erfindung benutzt, das eine Ver. stopfung von vornherein unmöglich macht, weil sich nun die physikalisch verflüssigte Masse während des Weiterströmens und Verdüsens etwa so wie eine reine Flüssigkeit verhält.Carrier liquid and then clog the channels. Eliminating of such secretions by more or less slowly vibrating clearing or Valve needles, which are also used in various ways to act on diesel engines Difficult-to-flow fuels, such as tar, have been proposed to go with the sweeping Liquefaction of the above-mentioned masses by rapidly oscillating needles in nozzles and channels nothing in common. Rather, it becomes the phenomenon protected in the main patent a thorough liquefaction according to the present invention used, the one Ver. Makes clogging impossible from the start, because now the physically liquefied Mass as it continues to flow and atomize is roughly the same as a pure liquid behaves.

Die zur Hervorbringung dieses Effektes notwendigen Nadeln können, wie im Hauptpatent beschrieben ist, beispielsweise an einer durch einen Wechseistrommagneten erregten Membran oder an einer ähnlich wirkenden Vorrichtung befestigt sein. Hierdurch wird erreicht, daß selbst plastische oder elastische Massen von hoher scheinbarer Zähigkeit sehr fein verdüst werden können, wobei außerdem in der Regel noch eine Energieersparnis erzielt wird, weil der Verdüsungsdruck und auch die Menge des gespannten Gases herabgesetzt werden kann. The needles necessary to produce this effect can as described in the main patent, for example on one by an AC magnet energized membrane or attached to a similarly acting device. Through this it is achieved that even plastic or elastic masses of high apparent Toughness can be atomized very finely, and usually also a Energy saving is achieved because of the atomizing pressure and also the amount of tensioned Gas can be reduced.

Die Vorrichtung kann Anwendung finden bei Verdüsungen> die mit Hilfe von Zerstäubungstrocknern von Farbspritzpistolen oder in Düsen zur Beaufschlagung chemischer Apparate vorgenommen werden. Weiterhin können auch die Einspritzdüsen von Dieselmotoren, beispielsweise für die Anwendung von Fließkohle, gemäß vorliegender Erfindung ausgebildet sein. The device can be used for atomizations> those with With the help of spray dryers from paint spray guns or in nozzles for application chemical apparatus. Furthermore, the injection nozzles of diesel engines, for example for the use of fluidized coal, according to the present invention Invention be formed.

Die beiliegende Zeichnung stellt einen Querschnitt durch eine Düse dar, wie sie für Farbspritzpistolen Verwendung finden kann. Hierin bedeutet a den Flüssigkeitskanal, b den ihn umgebenden ringförmigen Preßluftkanal, c die im Flüssigkeitskanal eingebrachte, durch an sich bekannte elektromechanische Mittel zu transversalen Schwingungen angeregte, im Innern des Flüssigkeitskanals a befindliche Nadel. Mit Hilfe einer derartigen Vorrichtung kann beispielsweise auch eine thixotrope oder thixotrop gemachte Spachtelmasse ohne -Schwierigkeiten in feiner Verteilung verspritzt werden. The accompanying drawing shows a cross section through a nozzle how it can be used for paint spray guns. Here a means den Liquid channel, b the annular compressed air channel surrounding it, c in the liquid channel introduced to transversal by known electromechanical means Vibrations excited needle located inside the fluid channel a. With Using such a device can, for example, also be a thixotropic or Thixotropic leveling compound sprayed in fine distribution without difficulty will.
