Abstract:
A wire pickling apparatus comprising:a) an elongated tank having a cover, a bottom, two side walls, two opposing end walls, said end walls having horizontally aligned openings, and a plurality of partition means which divide said tank into a plurality of cells, at least two cells for water and a plurality of cells therebetween for pickling fluid,b) a means of sealing said horizontally aligned openings of said tank with water curtains in conjunction with rinse trays,c) a plurality of acid trays disposed in the pickling fluid cells,d) said acid trays having weirs at each end and a means of forming turbulence in conjunction with said pickling fluid flooding said acid trays and overflowing said weirs,e) said turbulence forming means comprises two opposed pipe headers located across said acid tray width, with a series of co-linear holes or nozzles in said pipe headers, each of said nozzles aligned substantially horizontally and longitudinally and positioned in said acid trays below a wire level in said acid trays for ejecting said pickling fluid into the bottom of said acid trays,f) means for passing wire horizontally from an entrance end of said tank, to an exit end of said tank, at a level of the top of said weirs which permits said wire to be submerged sequentially in the turbulent pickling fluid of said acid trays, whereby the turbulent pickling fluid of said plurality of acid trays will effectively clean said wire.
