Description

Technical Field

[0001] This application belongs to the technical field of aluminum electrolytic cells, and specifically relates to an operation-simple busbar connection mechanism during the shutdown of an aluminum electrolytic cell. Background Art

[0002] In the aluminum electrolysis industry, multiple electrolytic cells are usually set up for joint production, and these electrolytic cells are connected in a way of direct-current series conduction. Usually, due to industrial adjustment or other reasons, it may be necessary to shut down some electrolytic cells. When an electrolytic cell is shut down, the current is introduced from the incoming busbar into the anode column busbar. A short-circuit route is provided on the anode column busbar to directly introduce the current into the cathode busbar of this electrolytic cell, and then the current is introduced into the anode column busbar of the next electrolytic cell through the cathode busbar. When the current flows through the above-mentioned various conductive busbars, a busbar voltage drop will be generated. This voltage drop is a useless voltage drop and will consume electric energy. In order to reduce the electric energy consumed due to the useless voltage drop, when an electrolytic cell needs to be shut down, a connecting busbar can be added to reduce the consumed electric energy.

[0003] For example, the publication number: CN209702877U discloses an operation-simple busbar connection mechanism during the shutdown of an aluminum electrolytic cell, which includes multiple aluminum electrolytic cells. An anode column busbar and a cathode busbar are respectively connected to each aluminum electrolytic cell. A short-circuit route is provided between the anode column busbars and the cathode busbars of each unit. The anode column busbar of the latter electrolytic cell is connected to the cathode busbar of the previous electrolytic cell. A busbar connection device is provided between two adjacent electrolytic cells. The busbar connection device includes a connecting busbar and conductive plates provided at both ends of the connecting busbar. The two conductive plates are respectively fixed to the cathode busbars of two adjacent electrolytic cells through easily detachable fixing mechanisms. When the aluminum electrolytic cell is shut down, the present utility model can be conveniently connected into the equipment. The present utility model is convenient to disassemble, can reduce the busbar voltage drop and reduce the power consumption, and has significant economic value and social value.

[0004] However, it is found in the actual use process that: during wiring, the interface of the intermediate device for wiring is easily eroded by water.
