Description

Technical Field

[0001] The utility model relates to the technical field of zinc smelting technology, and more specifically, to an ammonia zinc smelting device. Background Art

[0002] Ammonia wet zinc smelting is a commonly used zinc smelting process. Its main principle is to use ammonia to react with zinc oxide at low temperature to generate ammonia zinc ions, and then reduce zinc metal by electrolysis. This process has the advantages of high production efficiency, high product purity and environmental protection. It is widely used in the zinc smelting industry. The process flow of ammonia wet zinc smelting mainly includes raw material treatment, wetting reaction, electrolytic reduction and product treatment.

[0003] Among them, electrolytic reduction mainly involves placing ammonia leaching liquid into an electrolytic cell for electrolytic reduction. By using an external current, the ammonia zinc ions are reduced to pure metallic zinc. The reduced zinc is deposited on the cathode in a solid form. The staff needs to bend down to take out the cathode plates one by one, which can easily increase the staff's waist injuries. In addition, the cathode plates are easily bumped against the electrolytic cell during the removal process, causing damage to the cathode plates and reducing their service life.
