Description

Technical Field

[0001] The utility model relates to the field of zinc smelting equipment, in particular to an electrolytic cell used for zinc smelting. Background Art

[0002] In the zinc smelting electrolysis process, there are many ways to overlap the anode and cathode plates. At present, the traditional process generally adopts a guide bar structure, which fixes the guide bar in the electrolytic cell. At the same time, a split insulating platform design is used between the electrolytic cells, and an inter-tank copper rod is set on the insulating platform. Although this method can ensure that the cathode plate does not move, there are problems such as poor positioning of the anode and cathode plates, large errors in the same pole distance, easy contact between the anode and cathode plates, serious blockage on both sides of the electrolytic cell, and heating of the copper rod that makes the plastic of the insulating platform easy to burn. It also leads to poor liquid fluidity and serious acid zinc depletion, which directly affects the precipitated zinc output and unit consumption. Utility Model Content

[0003] The utility model provides an electrolytic cell for zinc smelting, aiming at solving some or all of the problems existing in the background technology. In order to improve the liquid circulation in the cell, the electrolytic cell is designed with a connected insulating platform and provided with positioning slots so that the cathode plate and the anode plate can be accurately positioned. The guide strips in the cell are removed, cathode side strips are arranged on both sides of the cathode plate for insulation, and acid-resistant ceramic tiles are arranged under the copper rods between the cells and between the insulating platform to prevent the insulating platform from being burned out after the copper rods are heated.

[0004] The technical solutions provided by this utility model are as follows:

[0012] The utility model provides an electrolytic cell for zinc smelting, which is composed of a cell body, an anode plate, an insulating platform, an inter-cell copper rod, a ceramic tile, a glass fiber reinforced plastic cell, a cathode plate, and a cathode side strip. A glass fiber reinforced plastic cell is placed along the cell edge of the electrolytic cell, and its main function is to place the insulating platform so that all the insulating platforms become a whole and do not move. Multiple insulating platforms are placed in each glass fiber reinforced plastic cell, and positioning slots are arranged on the insulating platforms.
