Embodiment 1

[0028] Embodiment one: see Figure 1~5 , an emergency short-circuit device for an aluminum electrolytic cell, comprising a diversion bus 7, a crimping bus 3, a transition soft connection 5 and a clamp 1, the two ends of the diversion bus 7 are respectively fixed with a transition soft connection 5, and the transition soft connection The other end of 5 is welded and fixed to the crimping busbar 3, the crimping busbar 3 is fastened to the anode busbar 2 through the clamp 1, and the two sides opposite to each end of the diversion busbar 7 are respectively fixed with support beams 4, so The other end of the support beam 4 is placed on the anode busbar 2 of the downstream tank or the accident tank, the inner side of the crimping busbar 3 is fixed with a distance regulator 9, and the other end of the distance regulator 9 is fixed on the support beam 4 .

[0029] The distance adjuster 9 contains a support 9-1, a rotating screw 9-2, a wire sleeve 9-3 and a handwheel 9-4, and the supp...

Embodiment 2

[0032] Embodiment two: see Figure 1~5 When one or more electrolytic cells in the electrolytic series fail, the electrolytic series will be powered off, causing any part of the original short-circuit bus to be damaged. When an accident (such as hot electrolyte around) does not meet the operating conditions, the specific operation steps are as follows:

[0033] 1) Use the crane to lift the emergency short-circuit device a of the aluminum electrolytic cell through the lifting lug and place it on the anode large busbar on the power outlet side of the emergency electrolyzer and the anode large busbar on the power inlet side of the downstream tank, and adjust the crimping busbar through the distance regulator The distance and angle from the anode busbar make the crimping surface of the crimping busbar coincide with the outside of the anode busbar;

[0034] 2) Firmly crimp the crimped busbar and the anode busbar through the fixture;

[0035] 3) Gradually restore series power suppl...

Embodiment 3

[0040] Embodiment 3: It is basically the same as Embodiment 2, except that: when an accident occurs in the electrolyzer and both the short-circuit busbar and the upright busbar are damaged, the operation shall be carried out according to the above method.

Description

technical field [0001] The invention relates to the technical field of short-circuit treatment of aluminum electrolytic cells, in particular to an emergency short-circuit device and method for aluminum electrolytic cells. Background technique [0002] In the aluminum electrolysis industry, the electrolytic cell is the main equipment for the production of electrolytic aluminum, and generally hundreds of units are connected in series to form a production series. Under normal production conditions, the opening and stopping of the electrolytic cell is realized by operating the short circuit of the electrolytic cell after indirectly transferring the current through the high-current switch. At present, this technology has gradually matured. However, due to problems such as furnace building materials, furnace building technology or production management, accidents such as side and bottom leakage of the electrolytic cell, short-circuit busbar and short-circuit explosion may cause po...
