Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic zinc production, in particular to a palletizing and packaging device for electrolytic zinc sheets. Background Art

[0002] During the hydrometallurgical zinc electrowinning process, zinc deposits gradually form on the surface of the cathode plate in the electrolytic cell under the action of electric current. After a certain electrolysis cycle, the cathode plate is taken out of the electrolytic cell, and the deposited metallic zinc is peeled off manually or mechanically to obtain the required metal product. The cathode plate is then returned to the electrolytic cell to start a new round of metal deposition. This cycle continues to produce high-purity zinc flakes. After these zinc flakes are peeled off from the cathode plate, they are packaged and transported to the melting and casting workshop to be made into zinc ingots of uniform specifications and weight, which are the finished electrolytic zinc.

[0003] The zinc in the solution is adsorbed on the cathode plate to form a single body. When it reaches a certain thickness, it is stripped manually or mechanically. After stacking, it is directly transported by forklift or transported by chain to the melting and casting workshop. When mechanical zinc stripping is used, due to its high efficiency, manual stacking often leads to a series of problems such as a large consumption of labor and low efficiency, which is contrary to the concept of automated production.
