Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cobalt (nickel) or electrolysis, and more specifically to a reverse ear starting electrode sheet for producing electrolytic cobalt. Background Art

[0002] At present, the electrolytic cobalt (nickel) industry mainly uses the starting electrode as the cathode plate of the electrolytic cobalt (nickel) products. Due to the large electrolytic cobalt stress, the starting electrode of the seed plate slot is very easy to detach from the titanium plate and explode. The starting electrode is thin and easy to deform. The qualified rate of the produced starting electrode is low. The general processing process of the starting electrode includes: ear cutting by shearing machine, cutting of the starting electrode, punching of the earrings, leveling of the starting electrode, welding or riveting of the ear and the starting electrode, etc. In order to maintain the verticality of the lower slot electrolytic deposition, the manufactured starting electrode is generally fixed by a clamp frame. After the electrolytic cobalt plate is formed after a certain period of electrolytic deposition, the clamp frame is taken out;

[0003] The connection between the lifting ear and the starting electrode piece is generally made by welding, that is, the lifting ear and the starting electrode piece are fixed by welding. However, the thickness of the lifting ear and the starting electrode piece should be as thick as possible, otherwise it is easy to be perforated during welding. To meet the thickness requirement of the lifting ear and the starting electrode piece, the electroplating time of the seed plate needs to be extended, and the yield rate of the seed plate slot will be greatly reduced. In addition, the contact point of the lifting ear and the starting electrode piece must be fully welded during welding, because some welding points will be corroded and detached during electroplating, which will cause the lifting ear to warp or even fall off, affecting the continued electroplating of the starting electrode piece.

[0004] The utility model can mainly solve the problems that the welding points are easy to be separated and the lifting lugs are easy to be broken during the welding of the starting electrode piece and the lifting lugs. Utility Model Content

[0005] The utility model aims to solve the problem in the background, thereby providing a reverse lifting ear starting electrode piece for producing electrolytic cobalt.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A reverse lifting ear starting electrode for producing electrolytic cobalt comprises a starting electrode, grooves are provided on both sides of one end of the starting electrode, a lifting ear penetrates the inner side of the groove, a cable tie is installed around the end of the lifting ear, a conductive copper rod is suspended and connected at the end of the lifting ear away from the groove, and a conductive beam clamp is installed between the lifting ear and the conductive copper rod.

[0008] Furthermore, the thickness of the starting pole piece is 0.3-0.4 mm, and the size is 1030×880 mm.

[0009] Furthermore, the groove has a size of 95×2 mm.

[0010] Furthermore, the lifting ear is folded in half and passes through the interior of the groove, and the lifting ear on the inner side of the starting pole piece is folded in half at 180 degrees and flattened.

[0011] Furthermore, the lifting lug is hung on the inner side of the conductive copper rod, and the lifting lug and the conductive copper rod are fixed by a conductive beam clamp.

[0012] Furthermore, the conductive copper rod has a size of 38×6×1290 mm.

[0013] 1. The thickness of the lifting lug and the starting pole piece are 0.1-0.2mm and 0.3-0.4mm respectively, so the thickness requirements of the lifting lug and the starting pole piece are low, thereby improving the yield of the seed plate slot;

[0014] The process is simple to operate by reverse welding the lifting lug through the groove instead of full welding with a welding machine, and the electrodeposition at the lifting lug will not cause warping and deformation;

[0015] 2. The reverse ear process uses the pull of the ear to bear the increasing weight of the cobalt plate during electroplating, which is more reliable, while the welding process relies on the welding point to bear the weight of the cobalt plate. When the welding point corrodes, it is easy to cause the cobalt plate to separate from the ear and fall into the tank, affecting the continued electroplating and tank discharge;

[0016] 3. No welding process is used, so the production of the starting electrode can be mechanized, process-based, and continuous, thereby improving work efficiency. The reverse ear starting electrode has good verticality during electroplating, the ear has strong load-bearing capacity, and the ear is not easy to warp, deform, or corrode and break. It can greatly reduce the labor of subsequent operations such as slot surface leveling and short circuit processing, and improve the quality of electrolytic cobalt products.
