Description

Verfahren zum Reinigen von Gegenständen Die Reinigung von Gegenständen erfolgt außer durch mechanische Behandlung vor allem auch in -der Weise, daß man auf sie Reinigungsflüssigkeiten, z. B. wäßrige Lösungen von Salzen, wie Seife, Phosphaten usw., oder organische Lösungsmittel, wie Tetrachlarkohlenstaff, Trichloräthylen, Perchloräthylen, Benzin, Benzol u. d,gl., oder geeignete Mischungen verschiedlener, gegebenenfalls auch gegenseitig nicht löslicher Flüssigkeiten ,einwirken läßt. Während sich dünnschichtige fettige oder wasserlösliche Verunreinigungen mittels der genannten Reinigungsmifitel verhältnismäßig leicht entfernen lassen, ist die Entfernung dicker oder verkrusteter Fettschichten insbesondere mittels kalter Reinigungsflüssigkeit zeitraubend und die Befreiung der Gegenstände von anhaftenden Staubteilchen, z. B. Schmirgel- oder Lagerstaub, gelingt in den wenigsten Fällen. Besonders die Entfernung der letztgienannten Verunreinigungen mittels der üblichen Reinigungsmittel ist von großer praktischer Bedeutung, da eine Säuberung durch Handarbeit langwierig und teuer ist. Sie gelingt auch nicht in ausreichendem Maße durch die Einwirkung von Schallwellen allein ohne Anwendung von Flüssigkeit etwa in der bekannten Weise, wie der Staub von Absitzflächen trockener elektrischer Gasreiniger oder Metallteile aus Dämpfen von Röst- und Schmelzöfen entfernt werden. Bei dies'etn Verfahren kommt es nicht darauf an; d.aß auch die letzten Reste Staub -entfernt werden, die z. B. bei der Erzeugung von Schichten aus Metallen ,auf elektrolytischem Wege sehr störend wirken. Nach einem anderen Verfahren wird durch _ Schalleinwirkung das Niederschlagen von 'Klärmitteln in einer Flüssigkeit bewirkt; dabei handelt es sicli` jedoch nicht um das Reinigen von Geg4etiständen. '.Methods for cleaning objects The cleaning of objects takes place not only through mechanical treatment but also in such a way that one cleaning fluids on them, e.g. B. aqueous solutions of salts such as soap, phosphates etc., or organic solvents such as carbon tetrachloride, trichlorethylene, Perchlorethylene, gasoline, benzene and the like, or suitable mixtures of different, optionally also mutually insoluble liquids can act. While thin-layered fatty or water-soluble impurities by means of the above If the cleaning agent can be removed relatively easily, the removal is greater or encrusted layers of fat, in particular by means of cold cleaning fluid time consuming and the removal of the objects from adhering dust particles, e.g. B. emery or storage dust succeeds in very few cases. Especially the distance of the last-mentioned contamination by means of the usual cleaning agents is from of great practical importance, since manual cleaning is tedious and tedious is expensive. It also does not succeed to a sufficient extent through the action of Sound waves alone without the use of liquid, for example in the known manner, like the dust from the surfaces of dry electrical gas cleaners or metal parts removed from roasting and smelting furnace vapors. With these procedure it doesn't matter; d.that even the last remnants of dust are removed z. B. in the production of layers from metals, electrolytically very much have a disturbing effect. According to another method, the effect of sound is precipitation caused by 'clarifying agents in a liquid; but that is not the point about cleaning objects. '.

Es wurde ein Verfahren gefunden, welches eine praktisch völlige Reinigung oder Entstaubung von Ge'genständen aller Art auf einfache und wirtschaftliche Weise durch Anwendung von Schwingungen ermöglicht. Es besteht im wesentlichen darin, daß die Gegenstände in Berührung mit dem Dampf einer Flüssigkeit mit Ultraschallwellen beschallt werden. Besonders zweckmäßig ist es, die Gegenstände vorher oder nachher in der Flüssigkeit mit - Ultraschallwellen zu beschallen. Die Beschallung von Gegenständen in Berührung mit dem Dampf einer Flüssigkeit und daraufhin in der Flüssigkeit selbst ist beispielsweise dann vorteilhaft, wenn die Gegenstände so geformt sind, daß die durch die Beschallung Und die Wirkung der dampfförmigen Flüssigkeit von der Oberfläche abgelösten Verunreinigungen in Vertiefungen der Gegenstände o. d.-1. liegenbleiben, so daß es noch der nachfolgenden Spülwirkung in der Flüssigkeit und der Einwirkung der Beschallung bedarf, um die Verunreinigungen endgültig von den Gegenständen zu :entfernen. Aber auch der umgekehrte Fall kann eintreten, daß unter Einwirkung der Beschallung erst eine Behandlung in Flüssigkeit und dann im Dampf dieser Flüssigkeit zeveckmäßig ist. Letztere wird nämlich durch dauernde Aufnahme der ,abgelösten Verunreinigungen immer schmutziger, so daß binnen kurzem infolge des aus der Flüssigkeit stammenden, sich an der Ware anhängenden Schmutzes eine tadellose Säuberung durch die Flüssigkeit nicht mehr möglich ist. Demgegenüber enthält die dampfförmige Flüssigkeit keinen Schmutz, so daß durch das an den Gegenständen sich bildende reine Kondensat in Verbindung mit der schmutzlösenden Wirkung der Beschallung eine an die Reinigung in der Flüssigkeit anschließende vollständige Säuberung der Gegenstände möglich ist.A process has been found which is practically complete purification or dedusting objects of all kinds in a simple and economical way made possible by the application of vibrations. It consists essentially in that the objects in contact with the vapor of a liquid with ultrasonic waves be sonicated. It is particularly useful to check the items before or after in the liquid with - to sonicate ultrasound waves. The sound of objects in contact with the vapor of a liquid and then in the liquid itself is advantageous, for example, when the objects are shaped so that the by the sonication and the action of the vaporous liquid from the surface detached impurities in depressions of the objects o. d.-1. to lie down, so that there is still the subsequent flushing action in the liquid and the action the sonication is required in order to finally remove the contamination from the objects :remove. But the opposite case can also occur that under the action of the Sonication first a treatment in liquid and then in the vapor of this liquid is zeveck-like. The latter is namely due to the permanent absorption of the detached impurities dirtier and dirtier, so that within a short time as a result of the dirt adhering to the goods is impeccably cleaned by the liquid is no longer possible. In contrast, the vaporous liquid does not contain any Dirt, so that in connection with the pure condensate that forms on the objects with the dirt-dissolving effect of the sonication one of the cleaning in the liquid subsequent complete cleaning of the objects is possible.

Das Reinigen von Gegenständen durch Beschallung nur in der Flüssigkeit allein ist nicht Gegenstand der Erfindung.The cleaning of objects by sonication only in the liquid alone is not the subject of the invention.

Zur Behandlung der Gegenstände eignen sich beispielsweise offene oder geschlossene Metallreiniger, in denen sie der Einwirkung von dampfförmigen organischen Lösungsmitteln mit gegebenenfalls vorheriger oder nachheriger Behandlung in der Flüssigkeit selbst ausgesetzt sind.For example, open or open objects are suitable for treating the objects closed metal cleaners in which they are exposed to organic vapor Solvents with optionally prior or subsequent treatment in the Exposed to liquid itself.

Die Übertragung des Schalles auf das Reinigungsgut erfolgt in einer den jeweiligen Verhältnissen angepaßten Weise, z. B. derart. daß das Gut und/oder das I2einigungsmittel von dem SchaIlgeber angestrahlt oder -mit diesem verbunden wird. Als solche können an sich bekannte mechanische, thermische oder piezoelektrische Schallgeber verwendet werden. In vielen Fällen werden besonders günstige Ergebnisse erzielt, wenn als Reinigungsflüssigkeit zwei miteinander nicht mischbare Verbindungen, z. B. Wasser und Trichlorä:thylen, verwendet werden. Es bilden sich dabei innerhalb der ganzen Reinigungsflüssigkeit oder nur in Teilen derselben, vor allem an der Berührungszone der beiden Flüssigkeiten, sehr wirksame Emulsionen, deren Bildung gegebenenfalls durch Emulsio,nsmittel unterstützt werden kann. Es ist zweckmäßig, durch die Reinigungsflüssigkeit während der Beschallung geringe Mengen fein verteilter Gase hindurchtreten zu lassen, wodurch die havztation und damit die Scheuerwirkung der Flüssigkeit verstärkt wird. Außerdem ist es auch möglich, der Flüssigkeit fein verteilte feste Stoffe, z. B. Fasern, Holzmehl u. dgl., zuzusetzen, zwecks Beschleunigung und Erhöhung der Reinigungswirkung.The sound is transmitted to the items to be cleaned in one the respective conditions adapted manner, z. B. like this. that the good and / or the cleaning agent illuminated by the switch or connected to it will. As such, mechanical, thermal or piezoelectric known per se Sounder can be used. In many cases the results will be particularly favorable achieved if two immiscible compounds are used as cleaning fluid, z. B. water and trichlorethylene: ethylene can be used. It is formed within all or only parts of the cleaning fluid, especially the Contact zone of the two liquids, very effective emulsions, their formation can optionally be supported by emulsifiers. It is appropriate due to the cleaning liquid during the sonication, small amounts of finely distributed Allow gases to pass through, reducing the havztation and thus the abrasive effect the liquid is amplified. Besides, it is also possible to fine-tune the liquid distributed solids, e.g. B. fibers, wood flour and the like. To add for the purpose of acceleration and increase the cleaning effect.
