Embodiment 1

[0028] Example 1: see Figure 1~5 , A device for emergency short-circuiting of aluminum electrolytic cells, comprising a diversion bus 7, a crimping bus 3, a transition soft connection 5 and a clamp 1. Both ends of the diversion bus 7 are fixed with transition soft connections 5, and the transition soft connection The other end of 5 is welded and fixed to the crimping bus bar 3. The crimping bus bar 3 is fastened to the large anode bus bar 2 by a clamp 1. The two opposite sides of each end of the diversion bus bar 7 are respectively fixed with support beams 4, so The other end of the support beam 4 is placed on the large anode bus bar 2 of the downstream tank or the emergency tank, a distance adjuster 9 is fixed inside the crimping bus bar 3, and the other end of the distance adjuster 9 is fixed on the support beam 4 .

[0029] The distance adjuster 9 includes a support 9-1, a rotating screw 9-2, a wire sleeve 9-3 and a hand wheel 9-4, and the support 9-1 includes a first suppor...

Embodiment 2

[0032] Example 2: see Figure 1~5 When one or more electrolytic cells in the electrolytic series fails, the electrolytic series is cut off, causing any part of the original short-circuit bus to be damaged, and the short-circuit bus of the accident electrolytic cell is damaged and the bus around the electrolytic cell 12 is When the accident (such as hot electrolyte around) does not meet the operating conditions, the specific steps are as follows:

[0033] 1) Use a crane to short-circuit the aluminum electrolyzer a by lifting lugs and place it on the large anode busbar on the outlet side of the accident electrolyzer and the anode busbar on the inlet side of the downstream tank, and adjust the crimping busbar through the distance regulator. The distance and angle from the large anode bus bar make the crimping surface of the crimping bus bar coincide with the outside of the large anode bus bar;

[0034] 2) Crimp the crimped busbar and the anode busbar firmly by the clamp;

[0035] 3) R...

Embodiment 3

[0040] The third embodiment is basically the same as the second embodiment, but the difference is that when an accident occurs in the electrolytic cell and the short-circuit bus bar and the column bus bar are damaged, the operation is performed 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...
