Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic tank box covers, in particular to an automatic box cover for an electrolytic tank. Background Art

[0002] The electrolytic cell consists of a cell body, an anode and a cathode, and most of them use a diaphragm to separate the anode chamber and the cathode chamber. According to the different electrolytes, it can be divided into three categories: aqueous solution electrolytic cell, molten salt electrolytic cell and non-aqueous solution electrolytic cell. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolytic cell structure and rationally selecting the electrode and diaphragm materials are the key to improving current efficiency, reducing cell voltage and saving energy consumption.

[0003] With the continuous advancement of electrolytic aluminum technology, the capacity of electrolytic cells is getting larger and larger, and the flue gas generated during the electrolysis process is also increasing. The flue gas mainly contains CO2, CO, HF, and CF4 gases, so it is necessary to use a box cover to protect the electrolytic cell. The covers on traditional electrolytic cells are basically manual, which affects the working efficiency of the loading cell, so we proposed a new automatic box cover. Utility Model Content
