本发明涉及一种实验型电解锌装置，尤其适合教学和科研使用。The invention relates to an experimental electrolytic zinc device, which is especially suitable for teaching and scientific research.
背景技术Background technique
实验室电解锌装置是支持电解锌产业加工的重要元素，便于低成本先行开展系列工作，为电解锌生产早发现问题、解决问题，不断提升电解锌技术，有利于产生更好的社会、经济效益，良好的实验室电解锌设备是技术提升的有力支持。The electrolytic zinc device in the laboratory is an important element to support the processing of the electrolytic zinc industry. It is convenient to carry out a series of work at low cost, to find and solve problems early in the production of electrolytic zinc, and to continuously improve the electrolytic zinc technology, which is conducive to generating better social and economic benefits. , Good laboratory electrolytic zinc equipment is a strong support for technological upgrading.
目前，供教学和科研使用的实验型电解锌装置还处于起步阶段，主要存在以下缺陷限制了电解锌技术的发展，一是局部加补充液与局部液溢流排出没有良好的循环对流系统，使整个电解槽离子浓度分布不一致，从而影响电解，其次电解锌会产生大量热量，并且是电解锰产生热量的两倍以上，受物理规律影响电解槽液面表层温度很高，向下逐步降低，虽然生产中有冷却水循环冷却，但实验室很难做到这一点，并且由于表面温度较高还存在一定的安全隐患；二是极板与正负极铜条之间的接触不好、电阻很大，导致发热严重，影响电解效率和设备正常使用。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, which affects the electrolysis efficiency and the normal use of the equipment.
因此，现有的实验型电解锌装置不能适应教学和科研生产的需要，存在诸多的缺点和不足，需要进行改进。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.
