Definitions

  • the anode is characterized in that its anode surfaces are formed from two sheets of metal having the same configuration and joined to an anode riser such that all weld joints are symmetrically located relative to the axis of the riser.
  • the disclosed method involves a sequence of clamping all components during welding and maintains the various surfaces planar to eliminate warpage.
  • the disclosed apparatus permits the various steps of the method to be carried out simply and rapidly.
  • the subject invention is directed toward the art of electrolytic cells, especially alkali metal chlorate or bypochlorite and diaphragm-type chlor-alkali cells and, more particularly, to an anode assembly for use in such cells and a method and apparatus for forming the same.
  • Cells used for electrolysis of alkali metal halide brines usually employ a perforated metallic cathode.
  • a fluid-permeable diaphragm overlies the cathode and permits hydraulic flow of electrolyte from the anode chamber through the diaphragm and cathode into the cathode chamber.
  • the anodes described in the noted patent normally comprise an anode riser or conductor bar which supports members having an extended electrically conductive surface.
  • the surface can comprise any of several materials which have a sufficiently low chlorine overvoltage and which are chemically inert to the electrolyte and resistant to the corrosive conditions in the cell.
  • the many possible materials which can form the electrically conductive surface are discussed at length in the patent but, typically, comprise alloys of platinum group metals, oxides thereof, and mixtures of the metals and oxides.
  • the electrically conductive surface is normally supported from a sheet or member of a valve metal or alloy thereof; e.g., a film-forming metal such as titanium, tantalum, zirconium, niobium and the like.
  • the electrically conductive surface is supported on perforated or foraminous sheets, expanded metal of titanium.
  • two of the sheets are joined in parallel on opposite sides of the anode riser.
  • the anode riser itself is normally a titanium-clad copper electrode.
  • various types of cross braces and the like have been joined between the sheets.
  • the components making up the anode assembly, including the braces are joined by Welding.
  • the anode assembly In order for the anode assembly to function satisfactorily, it must have certain mechanical-structural char acteristics in addition to the chemical and electrical characteristics discussed in the aforementioned patent.
  • the sheets supporting the electrically con ductive surface must have a high degree of flatness. And, the flatness, must be maintained throughout extended periods of operation. This is required because irregularities in the surface vary the spacing between the anode assembly and the associated cathode assemblies. As a consequence, there are variations in current flow and reductions in the overall efficiency of the cell. Closely associated with the surface flatness requirement is the necessity for extreme parallelism and uniformity of spacing between the sheets of the anode assembly. Variations in these parameters have the same general effect on cell performance as lack of flatness.
  • the joints and/or bonds between the various components must exhibit uniform electrical conductivity as well as structural strength. This has best been achieved by joining the components with a series of closelyspaced spot welds.
  • the difficulties encountered in welding the assemblies have been substantial. First, titanium is inherently difficult to weld.
  • the presence of the electrically conductive surface of oxides greatly increases the welding difficulties.
  • the welding operation itself tends to result in warpage in the assembly. Consequently, the assembly must be straightened following the welding. In most instances, this has been a time-consuming manual operation.
  • the subject invention provides a dimensionally stable anode assembly and method and apparatus for forming the same which overcomes the above-discussed problems.
  • the preferred anode assembly comprises at least one generally cylindrical anode riser member having a pair of metal sheets, typically foraminous, joined to generally diametrically opposite sides thereof.
  • Each sheet has a major, generally planar, extent with first and second spaced edge portions with each joined to the riser member such that their respective planar extents are parallel and the first edge portion of each is generally parallel to and aligned with the second edge portion of the other.
  • the second edge portion of each sheet is bent to have an integral leg portion extending generally toward the first edge portion of the other sheet. Each leg portion terminates in a flange extending parallel to the first edge portion of the second sheet and joined thereto.
  • the flange portions are joined to a first edge of the associated sheet by a closelyspaced series of spot welds.
  • the sheets are preferably also joined to the riser by a similar series of spot welds.
  • the riser and the formed sheets can have an identical shape.
  • the assembly can be made with all weld lines or spots located symmetrically about all planes which contain the axis of the riser. It is believed that this tends to reduce or eliminate warpage encountered following welding of prior designs.
  • reconditioning of the assemblies i.e., cleaning and applying a new electrically conductive surface to the assembly
  • the absence of internal cross members or the like is believed to make it easier to hold the required surface flatness, as well as making it easier to return the assembly to its proper dimensional relationships following misuse or damage during use.
  • the structural arrangement permits the use of an improved method of fabricating the assemblies.
  • the preferred method includes the steps of:
  • the welding is accomplished by progressively spot welding a closely and relatively uniformlyspaced series of points along the assembly and parallel to the riser. Additionally, it is preferred that the leg portions also be clamped or otherwise rigidly held throughout their length during welding.
  • apparatus of the type contemplated includes a clamping platen assembly comprising three platen units.
  • Each platen unit comprises two platen members spaced by a longitudinally-extending gap which extends completely through the respective unit.
  • the three units are mounted in juxtaposed, stacked relationship with their longitudinal gaps in alignment.
  • the mounting means include means which permit the platen units to be moved between a first clamping position and a second spaced position for loading and removal of the assembly and components.
  • the platen units are sized so that the major areas of the sheets of the anode assemblies are engaged and clamped 'while the joint areas are exposed for welding.
  • the intermediate platen unit is arranged so that the anode riser is closely received in the longitudinal gap with the platen members of the intermediate unit substantially completely filling the space between the anode riser and the leg portions of the sheets.
  • the platen members making up the intermediate platen unit preferably include movable clamp bars which can be actuated laterally to clamp the leg portions of the sheets against fixed stops associated with the platen assembly.
  • These clamp bars determine the width and lateral contour of the assembly and, with this arrangement, all portions of the anode assembly are rigidly held during the welding operation.
  • the clamping platen assembly is associated with three sets of spot welding electrodes so that upon indexed, relative movement between the electrode and the platen assembly in a direction longitudinally of the assembly, all weld joints will be made somewhat simultaneously by providing relative movement between the electrodes and the assembly.
  • the platen aspressure. This relationship will be discussed at some length in the detailed description of the invention.
  • a primary object of the invention is the provision of a dimensionally stable anode construction which can be manufactured to required dimensional tolerances easier than prior art constructions.
  • Another object is the provision of an anode construction which uses a minimum number of components to achieve a structure in which the joints are symmetrically located relative to the center axis of the anode.
  • Still another object is the provision of method and apparatus by which anodes of the type discussed can be produced with substantial structural integrity.
  • a further object is the provision of a method and apparatus for forming anodes of the type described which overcomes problems previously encountered with respect to warpage and dimensional tolerance variations.
  • Yet another object is the provision of an apparatus for totally enclosing and clamping all major components of the anode assembly during the welding.
  • a further object is the provision of a method and ap paratus wherein all planar surfaces of the anode assembly are maintained rigidly in position throughout the welding operation.

  • FIG. 1 shows the overall arrangement of an anode assembly 10 of the general type described in US. Pat. No. 3,591,483 to Loftfield et al.
  • the anode assembly is shown as comprising an anode riser member 12 which carries and supports metal sheets which carry anode surfaces 14.
  • the anode riser 12 comprises a generally cylindrical member having a conductor core 16 formed from a copper tube (see FIGS. 2 and 3) which has a titanium cover 18 clad or otherwise applied to the tube.
  • the materials from which the assembly is constructed could vary.
  • the above-mentioned patent suggests several material combinations which have been found to be suitable.
  • titanium is preferred.
  • the upper end of the riser member 12 is closed by a titanium cap member 20 welded or otherwise sealingly joined thereto.
  • the cap member 20 serves to totally enclose and seal the copper core 16 at the upper end.
  • a mounting flange 22 Positioned about the lower end of the riser '12 is a mounting flange 22.
  • Flange 22 is formed from a titanium alloy and permits the unit to be suitably mounted to a base member not shown but described in the aforementioned patent.
  • a threaded copper insert 24 is received in the lower end of riser 12 to provide a means for connecting the assembly to a base.
  • the lower end portion of the riser 12 is provided with wrench flats 26 to facilitate installation and removal of the assembly.
  • the anode sheets could be formed from many different materials and have a variety'of different types of electrically conductive surfaces carried thereon; however, in the subject embodiment, the anode surfaces 14 are supported by foraminous titanium sheets, specifically sheets of 0.070 inch titanium metal expanded or perforated to form a mesh-like sheet best illustrated in FIG. 1A. Although the total open area could vary, in the subject embodiment, approximately one-half of the total sheet area is open as illustrated in FIG. 1A. Additionally, although not shown in FIG. 1, the sheets which carry the anode surface 14 are preferably uniformly perforated or open throughout their entire area.
  • first sheet 28 includes a first major planar portion 30 having a first end portion 32 and a second end portion 34.
  • the second end portion 34 has formed integrally therewith a short, bent leg 36.
  • the length of leg 36 is substantially equal to the outside diameter of the anode riser 12.
  • a continuous tab or flange portion 38 is bent to extend generally parallel to the surface of portion 30.
  • a second sheet member 40 is formed identically to sheet member 28. It includes a first major planar portion 30' having a first end 32' and a second end 34' A leg portion 36' extends from end portion 34 and terminates in a flange 38.
  • the sheets 28 and 40 are positioned adjacent the exterior of the anode riser 12 on diametrically opposite sides thereof.
  • the major extents 30 and 30' of the sheets 28 and 40 extend parallel to each other and are joined to the riser 12 by rows of spot welding 42.
  • the first ends 32, 32' of each sheet are parallel with and joined to the respective tab portions 38 and 38' of the second ends 34 and 34.
  • the ends are joined by separate series of spot welds 44 and 46.
  • the spot welds are located relatively uniform distances apart and a sufficient number are provided to join at least half or every other one of the individual strands of the mesh or expanded sheet to the anode riser or the adjacent sheet.
  • anode assemblies when constructed as described, can be maintained to a higher degree of flatness and within relatively rigid tolerance limitations. It is believed that this results from the symmetry of the assembly about any plane which includes the axis of the anode riser 12. Note that all weld joint lines are symmetrically located relative to one another. Additionally, a minimum number of components sufficient to provide this symmetry are utilized, and no internal cross braces or the like are positioned within the unit as has been attempted in certain prior art structures. Of course, if desirable, in large anodes some braces could be added.
  • An additional advantage present with the subject structure is that it is simpler and easier to recondition; i.e., applying a new oxide coating to the exterior surfaces of the anode sheets FIGS.
  • FIG. 4A-4D illustrate a preferred sequence of steps which can be used for forming the anode assembly of FIGS. l-3.
  • the sequence begins by positioning a first sheet 28 on a rigid, flat surface such as platen unit having two platen members 52 and 54 positioned and sized so as to engage substantially all portions of surface 30 except those areas required to be exposed for the welding operation.
  • the anode riser 12 is placed over the sheet 28 in its desired location and suitably supported and held in location.
  • the second sheet 40 is positioned over the sheet 28 and the anode riser 12.
  • a second platen unit 56 including relatively rigid, flat platen members 58 and 60 is positioned so as to substantially fill the spaces between the sheets 28 and 40 (see FIG. 4B).
  • a third platen unit 62 is moved into position against surface 30 of sheet 40.
  • Platen unit 62 similarly includes two platen members 64 and 66 sized and located so as to engage substantially the entire surface 30 except for those areas which must be exposed for performing the welding operation.
  • FIG. 4D illustrates an additional step which is preferred prior to the welding operation. Namely, the application of a clamping force F to the leg portions 36 and 36 to move them against fixed stops and hold them throughout the weld ing operation.
  • the spot welding can be accomplished by producing indexed relative movement between the platen assembly and three sets of spot welding electrodes 68, 69 and 70.
  • the welding electrodes 68-70 are located in alignment and are operated so that all three rows of spot welding are accomplished simultaneously or nearly simultaneously.
