Abstract
The utility model provides a cathode for copper electrodeposition and electrorefining, comprising a current conducting rod and a negative plate. The current conducting rod is connected to the negative plate by welding. The current conducting rod is made of a compound of three materials, wherein, the outer layer is made of stainless steel, the middle layer is made of copper, and the middle conducting core adopts A3 steel. The negative plate is made of stainless steel, the end face of the bottom is provided with a groove along the length direction. The utility model has the advantages of sound verticality, simple structure, low resistance of the contact points, sound conductivity, etc.
Description
The utility model relates to a kind of negative electrode that copper electrodeposition, electrorefining are used that is used for.The negative electrode that relates to kind plate (also claiming motherboard in the industry) negative electrode in traditional electrodeposition, the electrorefining technology and permanent cathode electrodeposition, electrorefining.
At present, in traditional electrodeposition, electrorefining technology, its kind plate negative electrode now is generally the titanium plate and makes.Adopt the hanger form to be connected between minus plate and the contact rod, or adopt the bolt connection.Its contact site very easily is corroded in the wet environment of actual production, contaminated.Influence its product quality and cause contact resistance to increase.For stabilized product quality must often be cleared up the contact-making surface of contact rod and pole plate, not only time-consuming but also require great effort, the service life of reducing kind of plate again.In permanent cathode method electrodeposition, electrorefining technology negative electrode now only odd must with two kinds of Ai Sha, and complex manufacturing technology.
The purpose of this utility model is exactly to avoid some defectives of prior art.And be embodied as the traditional copper electrodeposition, electrorefining kind plate negative electrode reliably uses, improve the quality of products.Reduce the personage that negative electrode safeguards and consume, improve contacting between contact rod and the minus plate, thereby the conduction uniformity between each minus plate in same electrodeposition, the electrolytic cell is improved to greatest extent.
The technical scheme that the utility model is realized is: be used for the negative electrode that copper electrodeposition, electrorefining use and be made up of contact rod and minus plate two parts.Adopt the mode of welding to be connected between contact rod and the minus plate.Contact rod is that three kinds of materials are composited.The outermost layer of contact rod is a stainless steel, and the intermediate layer is a copper, and middle fuse is the A3 steel.Bottom, contact rod two ends is an arc face shape, and the minus plate that is used for copper electrodeposition, electrorefining is a stainless steel, has a groove along its length at its bottom end face.
The utility model can directly be produced product as negative electrode in permanent cathode method copper electrodeposition, electrorefining technology, it is good to have up rightness, simple for structure firm, contact point resistance is low, conducts electricity very well, advantages such as same electrodeposition, interior each negative electrode conduction good uniformity of electrolytic cell.
Further introduce the utility model embodiment below in conjunction with accompanying drawing:
Fig. 1, example structure schematic diagram of the present utility model.
A-A cutaway view in Fig. 2, the example structure schematic diagram of the present utility model.
B-B cutaway view in Fig. 3, the example structure schematic diagram of the present utility model.
Contrast Fig. 1, the utility model comprises contact rod 1 and minus plate 3 two parts.Be welded to connect between contact rod and the minus plate, described contact rod 1 comprises the top layer 4 that stainless steel is made as shown in Figure 2, intermediate conductive layer 6 that copper material is made and contact rod fuse 5 three parts of being made by A3 steel material.The bottom, two ends of contact rod 1 is an arc surface.Described minus plate is made by stainless steel material as shown in Figure 3, and its bottom end face has a groove 7 along its length, is provided with nonmetal insulating packing in groove 7.
