Problems solved by technology

Obviously, this method cannot be fully applied to the electrolyzers at the feed end of each work area of ​​the aluminum electrolysis series, especially when the short-circuit port of the feed end electrolyzer fails
Once an accident occurs at the short-circuit junction, it is difficult to achieve emergency treatment in the existing way

Embodiment 1

[0023] Embodiment 1: see attached Figure 1-Figure 2 , an aluminum electrolytic series head slot emergency device, the head slot emergency device includes conductors 2 or three conductors 2 connected to each other through soft connections 3 of copper soft strips or aluminum soft strips, and the two connection ends of the head slot emergency device are respectively Two adjacent aisle busbars 1 connected to the electrolytic cell 4, each aisle busbar 1 is connected to the corresponding column busbar 5, and the middle section of the three conductors can be supported by a support frame.

[0024] Conductor 2 is made of aluminum or copper

[0025] The end conductor 2 of the head groove emergency device is connected and compressed with the aisle bus 1 through a crimping device 6 .

[0026] The crimping device 6 includes two pressing plates 601 and bolts 602. Between the two pressing plates 601, the end conductor 2 and the aisle bus 1 are pressed together and locked by the bolts 602. ...

Embodiment 2

[0030] Embodiment 2: see attached Figure 1-Figure 2 , when the connecting plate connecting the aisle busbar of the electrolyzer at the power inlet end of each work area to the upright busbar is faulty and cannot pass through, or the upright busbar has a condition and cannot pass through, this part of the current is transferred to the aisle busbar 1 through the emergency device of the head slot , lead to the aisle bus 1 of other groups and then enter the electrolyzer 4 at the power inlet end through the corresponding column bus, so as to continue to maintain the production of the electrolyzer.

[0031] The invention is used in the accident state of the head tank of the electrolysis series, such as the explosion of the short circuit, the emergency device of the head tank is used as a bypass device to temporarily pass the flow, so as to avoid the shutdown of the electrolysis series. When an accident occurs at the short-circuit port of the electrolyzer at the power inlet end of e...

Abstract

The invention discloses an aluminum electrolysis serial head groove emergency device. The head groove emergency device comprises a conductor, or three sections of conductors connected through soft connectors; two connecting ends of the head groove emergency device are connected with two adjacent aisle buses of an electrolysis tank; and each aisle bus is connected to a corresponding stand column bus. The aisle buses of the electrolysis tank at a power inlet end flow to the adjacent aisle buses through the head groove emergency device; the part of electricity enters short-circuit blocks by the corresponding stand column buses after being remained on the aisle buses and guided to the other sets of the aisle buses through the head groove emergency device, and enter tank periphery buses by theshort-circuit blocks to effectively solve accidents in a short-circuit port of the electrolysis tank at the power inlet end of each work area; and serial current is difficult to enter the tank periphery buses and connecting plates, connected with the aisle buses and the stand column buses of the electrolysis tank at the power inlet end of each work area, through the short-circuit blocks to cause faults or incapability of circulating the current due to failures of the stand column buses.

Description

technical field [0001] The invention relates to an aluminum electrolysis series head tank emergency device 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 transmission of the series ...
