ABSTRACT:
A system and method for removing drag-out adhering surface treating solutions from barrels and their loads of articles in bulk after electroplating and/or chemical surface treatments and the recovery (recycling) of said solutions. The system includes a barrel aggregate (5) for containing the load of articles (7) being treated, a device for moving the barrel between a position inside treatment container (1) and outside of and above the container which is filled with a treatment solution, a rigid half cylinder shell (2', 2") for partically embracing the barrel in its outside position above the container so that the half cylinder shell embraces only that upper part of the barrel which is not filled with the load, and a device (9) for supplying inside the half cylinder shell a stream of pressured air flowing first through the upper part of the barrel and in continuation through the load downwardly out of the barrel to remove the adhered drag-out solution from the barrel and load to flow directly back to the container.
