Problems solved by technology

Obviously, this method is not fully applicable to the power inlet terminal slot and the power outlet tail slot in each work area of ​​the aluminum electrolysis series
Because there is no downstream electrolyzer in the tail tank, it is difficult to bridge the current; and there is no upstream tank in the power inlet terminal tank, once an accident occurs at the short circuit, it is difficult to achieve emergency treatment with the existing method

Embodiment 1

[0026] Embodiment 1: see attached figure 1 , when used in the tail tank of the outlet end of each electrolysis work area, one side of the auxiliary emergency bus 1 is connected to the anode bus 4 of the electrolytic cell 7 at the outlet end by crimping, and the other side is connected by crimping The electric side bus 3, the electrolysis series current can enter the electric side bus 3 through the column bus 5 of the electrolytic tank 7 at the electric outlet, the anode large bus 4 and the auxiliary emergency bus 1.

[0027] The auxiliary emergency busbar 1 is connected to the anode main busbar 4 and the outlet side busbar 3 by crimping, and the crimping method adopts door-shaped clamps or bow-shaped clamps to crimp.

[0028] Such as Figure 5 shown, the bow clamp includes " "type clip 6 and screw 11," The "type clamping piece 6 snaps the anode large busbar 4, the power outlet busbar 3 and the auxiliary emergency busbar 1 into the slot and passes through the screw 11" T...

Embodiment 2

[0030] Embodiment 2: see attached figure 2 , when used in the inlet terminal slot of each electrolysis work area, one side of the auxiliary emergency bus 1 is connected to the anode bus 4 of the electrolytic tank 8 at the inlet end by crimping, and the other side is connected to the aisle bus at the inlet end 9 are connected by crimping, so the electrolysis series current can enter the anode busbar 4 of the electrolysis tank 8 at the power supply end through the aisle bus bar 9 at the power supply end, and finally enter the electrolysis series.

[0031] The auxiliary emergency busbar 1 is connected to the anode busbar 4 and the aisle busbar 9 at the power supply end by crimping, and the crimping method adopts door-shaped clamps or bow-shaped clamps to crimp.

[0032] Such as Figure 5 shown, the bow clamp includes " "type clip 6 and screw 11," The "type clamping piece 6 snaps the anode large busbar 4, the aisle busbar 9 at the power inlet end and the auxiliary emergency ...

Embodiment 3

[0034] Embodiment 3: see attachment image 3 , when used in the feed terminal slot of each electrolysis work area, one side of multiple sets of auxiliary emergency bus bars 1 is connected to the anode bus bar 4 of the feed end electrolyzer 8 by crimping, and the other side is connected by a transfer bus bar 10 is connected to the aisle busbar 9 at the power supply end by crimping, so the electrolytic series current can enter the anode busbar 4 of the electrolytic tank 8 at the power supply end through the aisle busbar 9 at the power supply end, and finally enter the electrolysis series. The transfer busbar 10 can lead the current of the two aisle busbars 9 at the feeder end into an auxiliary emergency busbar 1 .

[0035] The auxiliary emergency bus 1 adopts multiple groups, and one end of the multi-group auxiliary emergency bus 1 is connected to the anode large bus 4 of the electrolytic cell 8 at the power inlet end through the crimping method adopted in Embodiment 1 and Embod...

Abstract

The invention discloses an emergency device and method applicable to an aluminum electrolysis head cell and a tail cell. The device comprises a secondary emergency bus, wherein one end of the secondary emergency bus is connected to a big anode bus of an electrolysis cell at the electricity output end of each electrolysis operation area or a big anode bus of the electrolysis cell at the electricityinput end of each electrolysis operation area, and the other end of the secondary emergency bus is connected to a bus at the electricity output side or a bus in a channel at the electricity input end. According to the device, the big anode bus of the electrolysis cell at the electricity output end of the aluminum electrolysis series communicates with the bus at the electricity output side throughthe secondary emergency bus, and thus a current running loop is formed; and the structure of the device is completely applicable to a head cell in the electricity input end and a tail cell in the electricity output end of each operation area of the aluminum electrolysis series; and the problems that the current in the tail cell without downstream is hardly bridged and emergency treatment is hardly carried out in case of accident in a short circuit port of the head cell in the electricity input end without upstream can be effectively solved.

Description

technical field [0001] The invention relates to an emergency device suitable for aluminum electrolysis head tanks and tail tanks and an emergency method thereof, belonging to the technical field of aluminum electrolysis equipment. Background technique [0002] The electrolytic series is a closed circuit with strong current. The current direction of the operating state of a single electrolytic cell is: column busbar→anode horizontal busbar→anode guide rod→anode→electrolyte→aluminum water→cathode→cathode steel bar→cathode soft connection→busbar around the cell→column of the next cell Busbar; when the slot is stopped, the current direction is: column busbar → short-circuit opening → slot bottom busbar → column busbar of the next slot. [0003] In an accident state, if a short-circuit explosion occurs, there is no other way except to stop the accident electrolyzer urgently. The so-called rescue is to stop the accident slot as soon as possible and restore the normal power trans...
