Definitions

  • An object of our invention is to provide a simplified unitary apparatus which effects both water-washing and electrolytic cleaning of metal strands in a continuous operation.
  • a further object is to provide an apparatus of the foregoing type which includes a series of electrolytic cells and means for continuously circulating acid electrolyte through the cells.
  • a further object is to provide an apparatus of the foregoing type in which the end walls of each cell form electrodes encompassing the strand but out of physical contact therewith, and the electrodes of adjacent cells are separated by insulator blocks.
  • FIGURE 1 is a top plan view of our apparatus
  • FIGURE 2 is a side elevational view thereof
  • FIGURE 3 is an end elevational view thereof from the left of FIGURE 2;
  • FIGURE 4 is a vertical section on a larger scale on line IV-IV of FIGURE 1.
  • FIGURES 1, 2 and 3 show, our apparatus includes in succession a first water-washing section 10, an electrolytic-cleaning section 12, and a second water-washing section 13, all supported on a rigid frame 14.
  • a strand S travels continuously from left to right through these sections.
  • Each water-washing section 10 and 13 has respective outer and inner air inlets 15 and 16 and a water inlet 17 intermediate its two air inlets. We connect the inlets to air and water lines 18 and 19 (FIGURES 1 and 3).
  • the water-washing sections have air and water outlets 20 (FIGURES 2 and 4) which lead to tanks 21 in the lower portion of frame 14.
  • the electrolytic-cleaning section includes a series of alternating cathodic and anodic treatment cells 22 and 23 (three of each illustrated).
  • the first cell of the section is cathodic and the last anodic.
  • the headers lead to an acid supply, not shown.
  • the water-washing section 10 is formed of cylindrical nozzle holders 28, 29 and 30 and an acid overflow chamber 31, preferably of transparent plastic, held together with tie rods 32 and bolted to frame 14.
  • the outer end of the nozzle holder 28 carries a guide die 33 and a plate 34 holding the die in place.
  • the nozzle holder 28 has a central bore within which we insert a tubular air nozzle 35.
  • the air inlet 15 communicates with the nozzle through a vertical passage 36.
  • Nozzle 35 has a plurality of openings 37 which extend through its wall at an angle of about 30 to its central axis.
  • the nozzle holders 29 and 30 are alike.
  • Each has a respective chamber 38, counterbore 39 and vertical passage 40 through which the water and air inlets 17 and 16 communicate with the counterbore.
  • These nozzles have a plurality of openings 44 which extend through their walls at right angles to their central axes.
  • the acid overflow chamber 31 contains a vertical baflle 45 supported by rods 46. At its exit end the chamber carries a guide die 47.
  • the other water washing section 13 is of similar construction, except that the parts are reversed, and the openings which correspond with openings 37 extend at right angles to the central axis of the nozzle.
  • the cells 22 and 23 all are of similar construction. Each includes a respective inverted plastic T 52 which has an opening 53 in its bottom. A hose 54 connects the inlet header 26 with the T through the opening 53. Elbows 55 and a hose 56 connect the top of the T with the return header 27
  • flanged tubular electrodes 57 in each horizontal arm of the T. O-rings 58 prevent leakage of electrolyte between the electrodes and T.
  • the strand S In operation, we pull the strand S continuously through the apparatus. First air jets from nozzle 35, water jets from nozzle 41 and air jets from nozzle 42 act on the strand to remove loose foreign material and blow off the water.
  • the strand After passing through the acid overflow chamber 31, the strand enters the first cathodic treatment cell 22 where current is introduced from the electrodes 57 through the electrolyte without direct contact between the electrodes and strand. The current flows through the strand, the electrolyte in the adjacent anodic treatment cell 23, and the electrodes 57 of the latter cell. Electrolytic action in the cathodic cells removes most remaining foreign material from the surface of the strand, but deposits a smut. Electrolytic action in the anodic cells removes the smut.
  • the air and water jets in the second water-washing section 13 remove electrolyte from the strand and dry it, leaving a perfectly clean surface. Electrolyte flows continuously through the cells and thus carries away material cleaned from the strand.
  • the acid overflow chambers 31 receive electrolyte which leaks past the strand at the ends of the electrolytic-cleaning section.
  • the bafiles 45 direct such electrolyte downwardly through pipes 63 into the return header 27.
  • ourapparatus afl ords a simple effective means for cleaning a strand electrolytically, as well as washing it with water jets.
  • the electrodes fully encompass the strand without directly contacting it. Hence the current reaching the strand is uniform throughout the circumference and there is no arcing, as would damage the surface.
  • the entire apparatus is enclosed, preventing acid fumes from escaping to the atmosphere.
  • An apparatus for cleaning metal strands comprising in succession:
  • said electrolytic-cleaning section including:
  • cathodic and anodic treatment cells each of which is formed of:
  • positive and negative current supply means connected to the electrodes of said cathodic and anodic treatment cells respectively;
  • said water-washing sections having overflow chambers for receiving electrolyte from the end cells of the series.
