Detailed Description

The utility model relates to a copper electrolysis conductive copper bar, technical scheme is that it is provided with the bellied protruding muscle 11 that makes progress on the row 10 to lead electrical drainage, and the length direction of protruding muscle 11 is perpendicular with the row 10 length direction that leads electrical drainage, and the top of protruding muscle 11 is leading electrical drainage 10 length direction equidistance interval arrangement.

In the above technical solution, because the tops of the ribs 11 are equidistantly arranged in the length direction of the conductive bar 10, when the hangers 2 of the anode plate 1 are placed on the tops of the ribs 11, the polar distance between the polar plates is basically ensured, even if the anode plate 1 is not completely symmetrically placed on the symmetrical plumbum surface of the electrical contact line or surface on the top of the ribs 11 in the plate thickness direction, the positions of the polar plates can be properly adjusted according to the top of the ribs 11 as a reference, so that the polar plates are wholly or basically symmetrically placed on the tops of the ribs 11, which is very convenient to implement, the length direction of the ribs 11 is perpendicular to the length direction of the conductive bar 10, which not only can provide enough electrical contact area, but also can ensure the reliability of support when the anode plate 1 has position deviation in the width direction of the electrolytic tank, and facilitates the flow of the cleaning solution into the tank of the electrolytic tank when the electrolytic tank is cleaned, which acts as a stop the cleaning solution when the ribs are arranged in the same direction as the length direction of the conductive bar in the prior art All are different.

Specific examples of the ribs 11 are described in detail below.

In one basic solution, as shown in fig. 5a, 5b, 5c, 5d, 6a, 6b, 7a, 7b, the upper contour 111 of the bead 11 is smoothly curved.

Another basic solution is that the top of the bead 11 is a rectangular plane, i.e. it is understood that its upper contour 111 is a rectangular plane lying in a horizontal plane, as shown in fig. 5 d.

In the two basic schemes, the smooth arc-shaped top of the former can be regarded as a line, and the area of the contact part of the smooth arc-shaped top and the lower bottom surface of the hanging lug 2 of the anode plate 1 is a surface or the line is decided by the shape of the lower bottom surface of the hanging lug 2. In the latter case, the top of the rib 11 is a rectangular plane, and the area of the contact portion with the lower bottom surface of the hanger 2 of the anode plate 1 is a surface or a line depending on the shape of the lower bottom surface of the hanger 2.

The following describes the specific scheme of the upper profile 111 of the bead 11 being smooth and curved:

the cambered surfaces at two sides of the arc top of the convex rib 11 are symmetrically arranged on the plumb bob surface passing through the arc top. The shape-called ribs 11 are used as a reference to adjust the position of the anode plate 1 for easy observation and control. The preferred smooth arcuate solutions are two of the following:

one is that the cross section profile of the convex rib 11 is circular arc.

And secondly, the cross section outline of the convex rib 11 is in an elliptic arc shape, and the arc surfaces at two sides of the arc top are symmetrically arranged on the plumb bob surface passing through the arc top.

In the first scheme, when the circular arc is selected, the symmetry is satisfied at any time; for an elliptical shape, the curve where the arc is located is the long axis end or the short axis end is chosen to meet the symmetry requirement. In the two schemes, the outline of the convex rib 11 is only formed by one curve, and is simple. As the rib 11, it is also possible to select a configuration in which the cross-sectional profile of the upper profile 111 is circular arc; it is also possible that the cross-sectional profile of the upper profile 111 is an elliptical arc, for which arc solution the arc surfaces on both sides of the arc top are required to be arranged symmetrically to the plumb surface passing the arc top.

For the above solution, that is, when the rib 11 includes the upper contour 111 whose cross-sectional contour is circular arc or elliptical arc, the cross-sectional contour of the rib 11 is the lower contour 112 of square, as shown in fig. 6a, and as shown in fig. 6b, the cross-sectional contour is rectangular, and four corners are cut in the manner of arc contour to obtain the cross-section of square-round contour, and then the cross-section is cut along the symmetry line of the long side to obtain two ribs 11.

As shown in fig. 7a and 7b, the rib 11 in fig. 7a can be cut from the raw material of the cross section of fig. 7b to form a circular arc profile at two opposite corners, and the blank is cut along the bisector of the other two corners to obtain two ribs 11, which can save the cost of the rib 11. The lower contour 112 of the bead 11 in fig. 7a is then a bilaterally symmetrical bevel.

When the scheme of fig. 5, especially the circular arc profile shown in fig. 5c is selected, a stamping operation can be performed on the copper bar body to form the convex rib 11. The bottom size of the convex rib 11 can correspond to the thickness of the anode plate, the position of the anode plate can be determined by the bottom position of the convex rib 11 during adjustment, for the scheme shown in fig. 6, the lower size of the convex rib 11 can be selected to be consistent with the thickness of the hanging lug 2 of the anode plate 1, a fork rod tool with the front end being a U-shaped fork is provided, the opening of the U-shaped fork is slightly larger than the thickness of the hanging lug 2, and when the U-shaped fork is simultaneously provided with the hanging lug 2 and the convex rib 11, the hanging lug 2 is centered and symmetrically arranged on the convex rib 11.

The utility model relates to redesign the copper electrolysis conductive copper bar, the convex rib which is originally configured according to the two sides of the electrolytic bath and has a semicircular or elliptic cross section and is arranged along the length direction of the conductive copper bar is changed into the convex rib with the length consistent with the groove width and is arranged on the conductive copper bar at equal intervals, when the lugs 2 of the lug parts of the cathode and the anode are arranged on the convex rib 11, the lug parts of the cathode and the anode are in point or line contact with the semicircular or elliptic convex rib on the conductive copper bar, and also can form surface contact, the suspension purpose of the cathode and the anode is achieved by completely depending on the self weight of the polar plate, the consistency of the polar distance between the cathode and the anode in the groove is ensured, the current density is equal, the short circuit of the cathode and the anode in the groove is greatly reduced, along with the continuous electrolysis, the cathode and the anode can be changed according to the dissolved and separated weight, the suspension of the cathode and the anode plate is always automatically corrected to keep the suspension of the cathode and the anode plate, thereby achieving the consistency of the polar distance between the cathode and the anode, creates a good electrolytic environment for copper electrolysis.
