Aluminum electrolysis cell with end face electricity outgoing

Abstract

The invention discloses an aluminum electrolysis cell with end face electricity outgoing, is used for solving the problems that because a conventional aluminum electrolysis cell generates electricity from side faces, a large number of cell circumference busbars are required to be constructed, the investment cost is greatly increased, the cell separation distance is relatively large and the land occupation area is increased, and at the same time, the side face electricity outgoing makes the horizontal current quite large and is not conducive to electrolysis cell stability; the aluminum electrolysis cell includes a cathode carbon block and a cathode bar, the cathode carbon block is provided with a bar groove, the bar groove is internally provided with the cathode bar along the length direction, the bar groove passes through a cell shell at an electricity outgoing side of the electrolysis cell. The aluminum electrolysis cell is used for industrial production of metal aluminum.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a cathode structure for enabling an aluminum electrolytic cell to discharge electricity at one end of the electrolytic cell adjacent to a downstream cell. Background technique [0002] The current flow direction of the existing aluminum electrolytic cell is as follows: after the current flows through the busbar around the upper tank to the column busbar of the tank, the current flows through the column busbar through the large busbar and the balance busbar, and then flows through the anode through the large busbar, and then flows through the electrolyte and aluminum liquid , and then flow to the cathode, and finally flow from the cathode to the lower platform through the busbar around the tank. [0003] The structure of the cathode carbon block is as follows: each group of cathodes is composed of the following three parts: a cathode carbon block, two or four cathode steel rods, and a paste...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an aluminum electrolytic cell with end-face electricity discharge to solve the problem that the existing aluminum electrolytic cell is powered from the side and needs to be equipped with a large number of busbars around the cell to pass the side electricity outlet end of the electrolytic cell through the electrolytic cell. The power outlet is connected to the power inlet of the downstream tank, which greatly increases the investment cost, and also makes the tank spacing larger, increasing the floor space. At the same time, the side power outlet makes the horizontal current very large, which is not conducive to the stability of the electrolytic tank.
