The invention discloses an emergency short-circuiting device for an aluminum electrolysis cell, and relates to an emergency treatment device in an aluminum electrolysis production process. The emergency short-circuiting device for the aluminum electrolysis cell comprises a pressure welding block I, flexible connection and a pressure welding block II which are connected together in sequence, wherein the pressure welding block I is in compression connection with a vertical column bus located below a short-circuiting port of the aluminum electrolysis cell; and the pressure welding block II is incompression connection with a cell circumference bus of the aluminum electrolysis cell. When a series current cannot easily enter the cell circumference bus through a short-circuiting block in the case of an accident at the short-circuiting port of the electrolysis cell, a current of the vertical column bus can be sequentially guided to the welding block I, the flexible connection and the pressurewelding block II, and enters the aluminum electrolysis cell from the cell circumference bus. Therefore, according to the emergency short-circuiting device for the aluminum electrolysis cell, an upstream electrolysis cell or a downstream electrolysis cell does not need to be connected; and the emergency short-circuiting device for the aluminum electrolysis cell is completely applicable to variousfault cases at the short-circuiting port, capable of avoiding the outage of electrolysis series, increasing the production efficiency and lowering the production cost, reliable in performance, high insafety, and easy to popularize and use.
