Abstract
Cleaning of objects from adhering liquid surface treating medium after galvanic and/or chemical surface treatment and recovery of the liquid medium is performed by lifting objects treated in a working container by a drum aggregate, bringing two half shells over the drum aggregate to embrace the latter so that at only a lower region of the drum aggregate a gap remains, and blowing a gas stream through the half shells to the drum aggregate so that an adhered treating medium is removed from the objects and flows directly back to the working container through the gap.
Claims18
An arrangement for cleaning objects from adhering liquid surface-treating medium after galvanic and/or chemical surface treatment and recovery of the liquid medium, comprising
- a working container;
- a drum aggregate for accommodating objects and means for moving said drum aggregate between two positions inside and outside of said working container;
- two half shell means for embracing said drum aggregate in said outside position so that a gap between the shells remains only in a lower region of the drum aggregate;
- and means for supplying a gas stream through said half shells to said drum aggregate so as to remove the adhered treating medium from objects and directly flow the same back to said working container through said gap.
A method of cleaning objects from adhering liquid surface treatment medium after galvanic and/or chemical surface treatment and recovery of the liquid medium, comprising the steps of
- accommodating objects to be treated in a drum aggregate;
- lowering the drum aggregate into a working container of said liquid so as to contact the objects with said liquid;
- lifting the drum aggregate out of the working container after treating the objects in the liquid;
- bringing two half shells above the drum aggregate to embrace the latter so that only in a lower region of the drum aggregate a gap between the shells remains;
- and
- blowing a gas stream through the half shells to the drum aggregate so that adhered liquid treating medium is removed and flows directly back to the working container through the gap.
