Description

Technical Field

[0001] The invention relates to a connector for electrodes of an electrolytic cell, in particular to a hanging plate type electrolytic copper powder cathode conductive rod and a cathode conductive device. Background Art

[0002] The plate-mounted electrolytic copper powder cathode conductive rod is a device used to suspend and support the cathode plate of the electrolytic copper powder and conduct electricity. When in use, the conductive rod passes through the metal strip-shaped hanging ears fixedly connected to the cathode plate, and then the two ends of the conductive rod are supported on the insulating adjustment plate, and one end of the conductive rod is also in contact with the conductive bar, so that the cathode plate is suspended and supported in the electrolytic cell through the conductive rod and obtains current for electrolysis. In actual use, the conductive rod will heat up in the process of continuously conducting current to the cathode plate. In addition, the conductive rod has to bear the weight of the cathode plate for a long time. Therefore, the conductive rod is prone to deformation under the action of temperature increase and the gravity of the cathode plate for a long time. After the conductive rod is deformed, the end of the conductive rod will be tilted, which will reduce the current conduction area between the conductive bar and the conductive bar, further aggravating the heating of the conductive rod, thereby greatly shortening the life of the conductive rod, and at the same time, it will also cause a significant increase in electrolysis energy consumption, and will also affect the electrolysis effect of the cathode plate.

[0003] Chinese patent document CN209010620U discloses a copper electrolysis cathode conductive rod, comprising a stainless steel sleeve and a solid copper rod, wherein the solid copper rod is wrapped with a stainless steel sleeve, and the stainless steel sleeve and the solid copper rod are tightly combined with each other by interference fit without gaps; the wrapped solid copper rod is exposed for a distance by milling the stainless steel sleeve to form a contact for connecting to the conductive busbar. The cross section of the solid copper rod is a rectangular structure. The copper content of the solid copper rod must meet the T2 requirement, and the arc angle radius of the four corners of the cross section of the solid copper rod should be less than 0.5 mm. The cross-sectional width of the solid copper rod must be between 24 mm and 30 mm, and the cross-sectional height must be between 34 mm and 44 mm. The wall thickness of the stainless steel sleeve must be between 3 mm and 4 mm. The contact is located on the same side of the width direction of both ends of the solid copper rod. The beneficial effects of the prior art are: the cross section of the solid copper rod is rectangular, the bottom contact surface is large, and it is a conductive rod that reduces contact resistance and improves current efficiency, greatly improving the performance of the cathode plate.

[0004] However, in the prior art, the conductive rod is in the shape of a rectangular parallelepiped as a whole, and is formed by concentric interference fit between a solid copper rod and a stainless steel sleeve, and a side surface of the end of the stainless steel sleeve is milled to expose the solid copper rod to form a contact point. When such a conductive rod is used to hang the cathode plate through the hanging ear and electrolyze, it is found that the conductive rod is still overheated, the electrolysis energy consumption is relatively high, and the electrolysis effect of the cathode plate is still not very ideal. Summary of the invention

[0005] The purpose of the present invention is to provide a hanging plate type electrolytic copper powder cathode conductive rod to solve the problem that the hanging plate type electrolytic copper powder cathode conductive rod in the prior art is prone to excessive heating.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a hanging plate type electrolytic copper powder cathode conductive rod, including a conductive head and a support rod, the conductive head is connected to the end of the support rod, the conductive head is provided with a conductive contact plane, and the support rod is provided with a supporting curved surface for cooperating with a hanging ear.

[0007] The beneficial effects of this basic scheme are: by configuring the conductive rod to be composed of a conductive head and a support rod, and by arranging a conductive contact plane to increase the conductive area of ​​the conductive head, a supporting curved surface is arranged on the conductive rod to contact the hanging ear of the cathode plate. Compared with the prior art in which gaps easily appear on the contact surface between the hanging ear of the cathode plate and the square conductive rod, the supporting curved surface increases the effective contact area between the conductive rod and the hanging ear of the cathode plate when in use, thereby greatly reducing the excessive heating of the conductive rod, which is beneficial to increasing the service life of the conductive rod; at the same time, the conductive rod can stably conduct current to the cathode plate, which is beneficial to improving the electrolysis effect of the cathode plate.

[0008] Preferably, the supporting curved surface is an arc surface. With such a configuration, the contact between the supporting rod and the hanging ear can be good, and the force on the supporting rod can be more uniform, which is conducive to further improving the service life of the conductive rod.

[0009] Preferably, the support rod is cylindrical. With such a configuration, no matter how the conductive head adjusts the conductive contact plane, the effective contact area between the conductive rod and the hanging ear of the cathode plate remains unchanged during use, which is beneficial to improving the stability of the conductive rod in conducting current.

[0010] Preferably, the cross section of the conductive head is square. With such a configuration, when each side surface of the conductive head is used as a conductive contact plane, the contact surface resistance of the conductive rod remains unchanged, which is conducive to further improving the installation convenience of the conductive rod.

[0011] Preferably, a nickel-plated layer is provided on the surface of the conductive head and the support rod. More preferably, the thickness of the nickel-plated layer is 0.3-0.5 mm. Such a configuration is conducive to enhancing the conductive efficiency of the conductive rod and enhancing the corrosion resistance of the conductive rod, thereby helping to extend the service life.

[0012] Preferably, the conductive head and the support rod are separately arranged, and the conductive head and the support rod are connected by a pin. With such an arrangement, it is convenient to process the conductive head and the support rod with different materials, which is conducive to further improving the performance of the conductive rod.

[0013] In a second aspect, the present invention provides a plate-type electrolytic copper powder cathode conductive device, comprising an insulating partition and a cathode conductive rod, wherein the cathode conductive rod is any one of the above-mentioned cathode conductive rods, and the end of the support rod away from the conductive head is in contact with the insulating partition. With such a configuration, the cathode conductive device can better support and conduct electricity to the cathode plate, thereby facilitating the improvement of the service life of the cathode conductive device and the electrolysis effect of the cathode plate.

[0014] Preferably, the insulating partition is a light-colored PP board. With such a configuration, when the conductive rod is in a state of overheating for a long time, the light-colored insulating partition will turn black due to long-term heating, so that it is convenient to judge whether the conductive rod is overheated by observing the color of the insulating partition, thereby improving the convenience of discovering abnormal conditions of the cathode conductive device, which is conducive to reducing the maintenance cost of the cathode conductive device.

[0015] Preferably, the insulating separator is a white PP plate. With such a configuration, the difference in color change of the insulating separator is more prominent, which is conducive to more timely discovery of abnormal conditions of the cathode conductive device and processing.

[0016] The present invention has the following beneficial effects: 1. The present invention arranges the conductive rod into two parts, a conductive head and a support rod, and increases the conductive area of ​​the conductive head by arranging a conductive contact plane. The conductive rod is provided with a support curved surface to contact the hanging ear of the cathode plate. Compared with the prior art in which gaps easily appear on the contact surface between the hanging ear of the cathode plate and the square conductive rod, the support curved surface increases the effective contact area between the conductive rod and the hanging ear of the cathode plate when in use, thereby improving the conductive effect of the conductive rod, thereby solving the problem of excessive heating of the conductive rod and being beneficial to increasing the service life of the conductive rod.

[0017] 2. The present invention combines a square conductive head with a cylindrical support rod, so that the conductive rod is easy to operate in hanging cathode plates and adjusting the spacing between cathode plates, which is conducive to improving ease of use. At the same time, the conductive rod has good contact with the hanging ear of the cathode plate when in use, which solves the problem of excessive heating of the conductive rod and is also conducive to improving the electrolysis effect of the cathode plate.

[0018] 3. The present invention, by plating nickel on the surface of the conductive rod, is beneficial to improving the conductive performance of the conductive rod while extending its service life.

[0019] 4. The present invention uses a light-colored PP board as an insulating partition, so that the abnormal situation of excessive heating of the cathode conductive device can be more easily discovered, thereby reducing the maintenance cost of the cathode conductive device.
