Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 and 3, the present embodiment provides an anode structure for efficiently producing an electrolytic nickel cake, comprising an anode metal basket 2, the anode metal basket 2 being adapted to be immersed in an electrolyte, and the anode metal basket 2 containing a nickel anode material 1 therein. In some embodiments, the anode metal basket 2 is an anode titanium basket. The anode titanium basket adopted by the anode metal basket in the electroplating industry at present is high in strength, light in weight, corrosion-resistant and coated with an oxide film on the surface, the oxide film can prevent current from passing through the anode titanium basket under normal electroplating conditions to enable the current to directly pass through a nickel anode material in the titanium basket, and the surface of the anode metal basket 2 is connected with a conductive hook 4. An auxiliary conductive rod 3 is inserted into the anode metal basket 2, and one end of the auxiliary conductive rod 3 is connected with a conductive hook 4. The auxiliary conducting rod 3 comprises a central copper rod 301, and the outer surface of the central copper rod 301 is wrapped with a titanium coating 302. In some embodiments, the titanium cladding 302 has a uniform thickness, and the titanium cladding 302 has a thickness of 1.0mm to 1.2mm. The central copper rod is a solid central copper rod instead of a hollow central copper rod, so that the sectional area of the conductor can be increased, and the larger the sectional area of the conductor is, the larger the current allowed to pass through the conductor is.

This application is through being provided with supplementary conducting rod 3 in positive pole metal basket 2, supplementary conducting rod 3 is a conductor that can bear the weight of heavy current, through exerting heavy current to supplementary conducting rod 3, can improve current density, is convenient for promote the electrochemical reaction of positive pole department, is favorable to the generation of nickel ion. In addition, the center of the auxiliary conducting rod 3 is the central copper rod 301, compared with the anode metal basket 2, the conducting performance is good, heat is not easy to generate, and energy consumed by refrigerating the electroplating solution is saved. Meanwhile, the titanium coating layer 302 protects the central copper rod 301, so that the corrosion of the central copper rod 301 is prevented, and the pollution of electroplating solution is reduced.

In some embodiments, the number of the auxiliary conducting bars 3 is not less than one, and the cross-sectional shape of the central copper bar 301 is circular or square. Within a certain range, the more the number of the auxiliary conductive rods 3 is, the faster the efficiency of the electrolysis of the nickel anode material 1 is. In this embodiment, the nickel anode material 1 is in a strip shape, and the nickel anode material 1 may be nickel matte. The auxiliary conducting rods 3 are uniformly arranged on the anode metal basket 2, so that uniform electrolysis of the nickel anode material is facilitated, and the problem that after the electrolysis of part of the nickel anode material around the auxiliary conducting rods in the anode metal basket 2 is finished, part of the nickel anode material which is not in contact with the auxiliary conducting rods is not electrolyzed completely, and the efficiency is low is avoided.

In some embodiments, the auxiliary current-conducting rods 3 are perpendicular to or inclined from the bottom end of the anode metal basket 2, and the auxiliary current-conducting rods 3 are parallel to each other. The auxiliary conductive rods 3 arranged in parallel can reduce the occurrence of power utilization dangerous accidents caused by the mutual contact of the auxiliary conductive rods 3. Preferably, the auxiliary current conducting rod 3 and the bottom of the anode metal basket 2 are obliquely arranged, so that the contact reaction area of the auxiliary current conducting rod 3 and the nickel anode material 1 in the anode metal basket 2 can be increased, and the electrolysis speed is accelerated.

In some embodiments, the anode metal basket 2 comprises a mesh-shaped surrounding edge, a mounting bottom arranged at the bottom end of the mesh-shaped surrounding edge; and a positioning concave hole matched with the bottom end of the auxiliary conducting rod 3 is formed in the bottom of the installation. The positioning concave hole is beneficial to the clamping and embedding of the auxiliary conducting rod 3 and the placing, so that the auxiliary conducting rod 3 is prevented from inclining due to the subsequent one-way side pressure of the input nickel anode material 1, and further the auxiliary conducting rod 3 is contacted to cause power utilization accidents.

In some embodiments, the conductive hook 4 is located above the anode metal basket 2 and the auxiliary conductive rod 3, and the conductive hook 4 is externally connected to the positive electrode of the dc power supply.

Example 2

Along with the continuous progress of the electrolytic reaction at the anode structure, the nickel anode material 1 will also be consumed continuously, which will cause the impurity in the nickel anode material 1 or the size of the nickel anode material 1 itself to be smaller than the mesh size of the anode metal basket 2, and leak into the electroplating solution, thus affecting the progress of the reaction. By providing the insulating filter net 5, these substances can be prevented from leaking into the plating solution. In some embodiments, the insulating filter screen 5 may be an anode filter bag or an anode filter basket.
