Description
Verfahren zur Reinigung und Entfettung von Gegenständen Das Entfetten und Reinigen von Gegenständen mit Hilfe von Lösungsmitteln, insbesondere organischen Lösungsmitteln, ist an sich bekannt. Bei allen bisher angewandten Verfahren spielt die Verringerung der Verluste an Lösungsmitteln im Hinblick auf die Wirtschaftlichkeit eine große Rolle, und man hat deshalb versucht, die den Gegenständen beim Herausnehmen aus den Reinigungs- bzw. Entfettungsbädern noch anhaftenden Lösungsmittel möglichst zurückzugewinnen.Methods for cleaning and degreasing objects Degreasing and cleaning objects with the aid of solvents, in particular organic ones Solvents is known per se. It plays a role in all of the methods used so far the reduction in solvent losses in terms of economy plays an important role, and attempts have therefore been made to keep the objects out when they are removed Solvent still adhering from the cleaning or degreasing baths, if possible to win back.
Diese Zurückgewinnung erfolgt z. B. dadurch, daß man das noch anhaftende Lösungsmittel absaugt oder mittels eines Luftstromes abbläst und dann kondensiert. Trotzdem war es aber bisher nicht zu vermeiden, daß noch Teile des Lösungsmittels verlorengingen, weil erstens die Kondensation unvollkommen war und es zweitens nicht möglich war, das in den Poren der Gegenstände anhaftende Lösungsmittel vollkommen abzusaugen bzw. zu entfernen.This recovery takes place e.g. B. by the fact that one still adheres Sucks off solvent or blows it off by means of a stream of air and then condenses. In spite of this, however, it has hitherto not been possible to avoid that parts of the solvent are still present were lost because, firstly, the condensation was imperfect and, secondly, it was not was possible, the solvent adhering in the pores of the objects completely suction or remove.
Auch die Behandlung mit Warmluft bringt erst nach längerer Behandlungsdauer ein einigermaßen befriedigendes Ergebnis bei der Entfernung von Lösungsmittelresten aus den Poren von Gegenständen.Treatment with warm air only works after a long period of treatment a reasonably satisfactory result in the removal of solvent residues from the pores of objects.
Erst mittels der vorliegenden Erfindung ist es möglich, Gegenstände nach ihrer Reinigung mit Lösungsmitteln sofort restlos und ohne längeres Absaugen u. dgl. von anhaftendem Lösungsmittel zu befreien, wobei dasselbe ebenfalls restlos zurückgewonnen wird und infolgedessen keine Verluste eintreten. Das Verfahren besteht darin, daß die Gegenstände, welche das Entfettungsbad verlassen, nicht sofort an die Luft gebracht, sondern in ein Bad hineingetaucht werden, welches das Entfettungsmittel nicht oder nur wenig löst. In diesem Bad wird das anhaftende Lösungsmittel zum Verdampfen gebracht, wobei es sich von den gereinigten Gegenständen löst und aus dem Bad entweicht bzw. wieder aufgefangen wird.Only by means of the present invention is it possible to create objects immediately after cleaning with solvents without any residue and without prolonged vacuuming and the like to free from adhering solvent, the same also completely is recovered and as a result there are no losses. That The method consists in that the objects which leave the degreasing bath, not immediately brought into the air, but rather immersed in a bath, which the degreaser does not dissolve or only slightly dissolves. In this bath, the clinging becomes Solvent evaporated, whereby it was removed from the cleaned items dissolves and escapes from the bath or is caught again.
Obiges Bad schließt den Raum, durch welchen die Gegenstände hindurchgeführt werden, sobald sie das Reinigungsbad verlassen, ab, so daß dieser Raum nicht mit der Außenluft in Verbindung steht. Das Entweichen des verdampfenden Lösungsmittels wird durch Bewegung der Metallgegenstände beschleunigt, und zwar am besten durch ruckweise Bewegung, z. B. Schütteln, oder durch Bewegung des Bades. WeniZ das Lösungsmittel von den Metallgegenständen verdampft ist, werden dieselben aus dem Bad herausgenommen und an die Luft gebracht.The above bathroom closes the space through which the objects pass as soon as they leave the cleaning bath, so that this space does not come with is in communication with the outside air. The escape of the evaporating solvent is accelerated by moving the metal objects, and best by jerky movement, e.g. B. shaking, or by moving the bath. Less the solvent evaporated from the metal objects, the same are taken out of the bath and brought into the air.
Das von den Gegenständen verdampfte Lösungsmittel wird in den über den Bädern befindlichen abgeschlossenen Raum geführt oder gesondert aufgefangen und niedergeschlagen, um dem Entfettungsbad wieder zugeführt zu werden.The solvent evaporated from the objects will be in the over the enclosed space located in the bathrooms or collected separately and precipitated to be returned to the degreasing bath.
Nach einer anderen Ausbildung des Verfahrens gehen die Gegenstände direkt aus der Entfettungsanlage in das zweite Bad über. Die Temperatur desselben ist so gewählt, daß sie über der Siedetemperatur des Reinigungsbades liegt.After another formation of the procedure, the objects go directly from the degreasing system into the second bath. The temperature of the same is chosen so that it is above the boiling point of the cleaning bath.
Die Arbeitsweise des Reimgens kann von Hand, aber auch auf mechanischem Wege, z. B. durch laufende Bänder bewerkstelligt werden.Rhyming can be done manually or mechanically Ways, e.g. B. be accomplished by running belts.
Für die Reinigungs- und Verdampfungsbäder können mehrere oder auch nur ein Behälter gebraucht werden, in welchem sowohl die Reinigungsarbeit als auch das Abtreiben des anhaftenden Lösungsmittels stattfindet.For the cleaning and evaporation baths, several or also only one container is needed in which both the cleaning work and the driving off of the adhering solvent takes place.
