Description

Technical Field

[0001] The present invention belongs to the technical field of nickel deposition, and relates to a nickel deposition system with vibration exhaust, and particularly to a nickel deposition system with vibration exhaust and an exhaust method. Background Art

[0002] With the surging global demand for electrodeposited nickel and the skyrocketing price of nickel sulfate raw materials, in order to reduce production costs, enterprises generally adopt semi-extract / full-extract nickel sulfate. However, the oil content in the incoming materials is easily attached to the surface of the nickel plate to form pores, and the pores will not automatically rise and disappear without external stimulation, which will hinder the infiltration of the electrolyte and reduce the quality of electrodeposited nickel. In traditional workshops, workers use PP strips to knock on the copper bars of each nickel plate manually to generate vibration, so that the pores on the plate surface rise to the solution surface under the action of force, promoting the bubbles to rise and discharge. However, this method relies on manpower and cannot operate continuously, resulting in low efficiency.

Therefore, it is crucial to develop and design a new type of nickel deposition system and exhaust method. Summary of the Invention

[0116] Table 1

[0117] Qualified rate (%) Application Example 1 98 Application Example 2 97 Application Example 3 98 Application Example 4 92 Application Example 5 93 Application Example 6 94 Application Example 7 92 Comparative Application Example 1 89 Comparative Application Example 2 86

[0118] It can be seen from Table 1 that:

[0119] (1) During the electrodeposition of nickel, by using the exhaust method provided in Application Examples 1-3 of the present invention for exhaust, the finally obtained electrodeposited nickel products have high quality, that is, the qualified rate is high;

[0120] (2) By comparing Application Example 1 with Application Examples 4 and 5, it can be known that the vibration period of the vibration device in the exhaust method provided by the present invention will affect the exhaust effect; when the vibration period of the vibration device is 1-3 times per two hours, the exhaust method has a better exhaust effect. This is because at this vibration frequency, the tiny bubbles in the electrolyte can grow to the critical size. At this time, the vibration can concentrate the energy to break the adhesion force between the bubbles and the surface of the cathode plate 3, prompting them to detach efficiently; in addition, vibrating 1-3 times every two hours can avoid the liquid surface turbulence caused by continuous operation through intermittent vibration, reducing the risk of secondary bubble retention or fragmentation; in addition, vibrating 1-3 times every two hours, the vibration period is synchronized with the deposition rate of electrowon nickel, and it can also ensure the orderly growth of crystals to maintain the density of the nickel plate;

[0121] (3) By comparing Application Example 1 with Application Examples 6 and 7, it can be known that the vibration frequency of the vibration device in the exhaust method provided by the present invention will affect the exhaust effect; when the vibration frequency is 20-40 Hz, the exhaust method has a better exhaust effect. This is because when the vibration frequency is 20-40 Hz, it can not only overcome the viscous resistance between the bubbles and the nickel plate surface, but also avoid the electrolyte splashing or bubble fragmentation caused by high frequency;

[0122] (4) By comparing Application Example 1 with Comparative Application Example 1, it can be known that in the nickel deposition system provided by the present invention, by setting the vibration device on the copper row 5, compared with setting the vibration device at the bottom of each electrolytic cell in each deposition line 1, it not only reduces the adverse impact of vibration on the anode plate life, but also reduces the impact on nickel deposition during vibration, thereby improving the quality of the electrodeposited nickel products;

[0123] (5) It can be seen from the comparison between Application Example 1 and Comparative Application Example 2 that in the nickel deposition system with vibration exhaust provided by the present invention, a vibration device is provided on the copper busbar 5 corresponding to the deposition tank 2 in each deposition line 1. The vibration device is used to vibrate the copper busbar 5, so that the copper rod 4 connected to the copper busbar 5 vibrates, thereby driving the cathode plate 3 connected to the copper rod 4 to vibrate, so as to realize the vibration of the cathode plates 3 in all deposition tanks 2 in at least one deposition line 1 at the same time, improving the degassing efficiency; the nickel deposition system with vibration exhaust provided by the present invention can automatically vibrate the cathode plate 3 in the deposition tank 2 regularly and at a fixed point.
