Description

Technical Field

[0001] The utility model relates to the technical field of cathode plates of electrolytic cells, and in particular to a cathode plate of an electrolytic cell. Background Art

[0002] An electrolytic cell is a device that performs an electrolysis process, in which an external power source is used to drive a chemical reaction. In an electrolytic cell, electrical energy is converted into chemical energy, resulting in a redox reaction at the electrodes. Typically, an electrolytic cell contains two electrodes (cathode and anode) immersed in an electrolyte solution. When an external power source is connected to the two electrodes, the ions in the electrolyte gain or lose electrons at the cathode and anode, respectively, to form new compounds or decompose existing compounds.

[0003] In the prior art, when copper plates are processed, an electrolytic cell is usually used to accumulate and attach a layer of copper plates on the cathode plate, and then peeled off. When used as a cathode and accumulating copper ions during the electrolysis process, what actually occurs is the process of copper ions being reduced from the solution and deposited on the cathode surface to form solid copper. This process will form a metallic copper layer, that is, the copper ions have obtained electrons, converted into metallic copper, and attached to the cathode plate. Because the metallic copper layer needs to be peeled off from the cathode plate, the cathode plate cannot be made of copper, otherwise there will be a problem of difficulty in peeling. Usually, a steel plate is used as the cathode plate, so that it is more convenient to peel off the metallic copper layer. The conductivity of the steel plate is much different from that of the copper plate. The steel plate is only about 1 / 8 to 1 / 60 of the conductivity of copper, which causes the resistance of the reaction to increase and release more heat energy, affecting the purity of the electrolytic product, and damaging the service life of the surrounding electrode materials and interfering with the surrounding equipment, thereby causing irrational use of resources and energy.

[0032] In this embodiment, a notch 102 is provided. The design of the notch 102 can realize the exposure of the exposed portion 201 of the core 2. The exposed portion 201 is used to be directly connected to a power source, thereby bringing the high conductivity characteristic of the core 2 to the extreme; and the design of the notch 102 can also make the other parts of the core 2 except the exposed portion 201 to be well covered by the steel body 1, without any other exposed parts, thereby avoiding the reduction of conductivity of the equipment during long-term use.

[0033] Furthermore, there are two notches 102 , which are respectively located on two sides of the body 1 .

[0034] In the present embodiment, two notches 102 are provided, so that the exposed portion 201 is also two, and the two exposed portions 201 are both overlapped with the negative pole of the power supply, and the notch 102 on the body 1 is not a single existence, but two, and such a design may provide multiple interfaces, so that the exposed portion 201 of the core 2 can extend from different directions or positions, increasing the flexibility and functionality of the design.
