Problems solved by technology

[0003] At present, the experimental electrolytic zinc device for teaching and scientific research is still in its infancy. The following defects limit the development of electrolytic zinc technology. The ion concentration distribution in the entire electrolytic cell is inconsistent, which affects the electrolysis. Secondly, the electrolytic zinc will generate a large amount of heat, which is more than twice that of the electrolytic manganese. Affected by physical laws, the surface temperature of the electrolytic cell is very high and gradually decreases downward. Although There is cooling water circulation cooling in production, but it is difficult to do this in the laboratory, and there are certain safety hazards due to the high surface temperature; the second is that the contact between the electrode plate and the positive and negative copper strips is not good, and the resistance is large , leading to serious heating, affecting the electrolysis efficiency and the normal use of the equipment

[0004] Therefore, the existing experimental electrolytic zinc device cannot meet the needs of teaching and scientific research production, and there are many shortcomings and deficiencies, which need to be improved
