Description

Verfahren zum Entfetten und Reinigen von Gegenständen aus starren Werkstoffen Es ist bekannt, Gegenstände aus starrem Werkstoff, insbesondere aus Metall, durch Behandeln in Emulsionen aus Wasser und organischen, wasserunlöslichen Fettlösungsmitteln unter Zusatz von Emulsionsmitteln, z. B. durch Aufspritzen, zu entfetten und zu entstauben.Process for degreasing and cleaning objects made from rigid Materials It is known to produce objects made of rigid material, in particular from Metal, by treatment in emulsions of water and organic, water-insoluble Fat solvents with the addition of emulsifiers, e.g. B. by spraying, too degrease and remove dust.

Erfolgt das Spritzen der Emulsion in einem mit Luft gefüllten Gefäße, so entstehen durch die eintretende Zerstäubung innerhalb des Gefäßes lösungsmittelhaltige Nebel, die sich nur schwer niederschlagen lassen und, wenn sie in den Arbeitsraum austreten, Geruchsbelästigungen und Lösungsmittelverluste verursachen. Dieser Nachteil läßt sich vermeiden, wenn man das Spritzen mit warmer Emulsion in einem Gefäße vornimmt, das mit Lösungsmitteldämpfen völlig gefüllt ist. Man verwendet hierzu z. B. ein offenes, unten geheiztes und oben gekühltes Gefäß, in dem man dauernd Lösungsmittel verdampfen läßt. Die Dämpfe füllen dann unter Verdrängung der Luft das Gefäß bis zu dessen oberer gekühlten Zone, wo etwaiger überschüssiger Dampf niedergeschlagen wird. Innerhalb der so gebildeten Dampfzone kann mit Emulsion gespritzt werden, ohne ' daß dabei Nebelbildung eintritt.If the emulsion is sprayed in a container filled with air, in this way, solvent-containing substances are created within the vessel as a result of the atomization that occurs Fog that is difficult to knock down and when in the work area leak, cause odor nuisance and solvent losses. This disadvantage can be avoided by spraying with warm emulsion in a container, which is completely filled with solvent vapors. One uses this for. B. a open vessel heated at the bottom and cooled at the top, in which one is constantly solvent lets evaporate. The vapors then fill the vessel up to, displacing the air to its upper cooled zone, where any excess steam is deposited will. Emulsion can be sprayed within the vapor zone formed in this way, without the formation of fog.

Das Spritzen läßt sich aber auch in einem völlig abgeschlossenen Gefäßraume vornehmen. Ein solcher kann z. B. durch ein glockenartiges Gefäß gebildet sein, das mit der Öffnung nach unten in eine Flüssigkeitsschicht eintaucht: man kann dann das Waschgut in dem durch die Flüssigkeit abgeschlossenen Gefäßraume abspritzen, ohne daß aus diesem Nebel austreten können. Die Einführung des Waschgutes in den Spritzraum erfolgt ebenso wie seine Herausführung durch die Flüssigkeitsschicht hindurch, was sich auch fortlaufend in an sich bekannter Weise durch Förderketten, Förderbänder oder eine sonstige mechanische Fördereinrichtung, die motorisch angetrieben sein kann, vornehmen läßt- Wenn man als Absperrflüssigkeit ein entsprechendes Fettlösungsmittel verwendet, so kann man mit der Hindurchführung des Waschgutes durch diese Flüssigkeit seine Vor-und Nachbehandlung mit dem Fettlösungsmittel verbinden. Schließlich läßt sich die Fördereinrichtung auch noch dazu benutzen, um das gereinigte Waschgut durch einen Raum hindurchzuführen, in dem es getrocknet wird.However, the spraying can also be carried out in a completely closed vessel space make. Such can be, for. B. be formed by a bell-shaped vessel, that is immersed in a layer of liquid with the opening facing downwards: then you can spray the items to be washed in the container space closed by the liquid, without being able to emerge from this fog. The introduction of the laundry in the The injection chamber takes place as well as its lead out through the liquid layer through, which is also continuously in a known manner by conveyor chains, Conveyor belts or any other mechanical conveyor that is motor-driven can be made - if you use a suitable fat solvent as the shut-off liquid used, so you can with the passage of the laundry through this liquid combine its pre- and post-treatment with the fat solvent. Finally lets The conveyor can also be used to carry the cleaned items through pass a room where it is dried.
