Method and an apparatus for improving single bus double-anode elevator decrease synchronism

Abstract

The invention discloses a method and an apparatus for improving single bus double anode elevator decrease synchronism, and the method and apparatus connect and separate an anode elevator (21) and an anode elevator (22) by two transmission separators (1) equipped between the anode elevator 1 (21) and the anode elevator (22), and when the anode bus (4) decreases, only one motor works, thereby the decrease of the anode bus (4) is consistent, and when the anode bus (4) lifts, two motors work, thereby providing enough lifting power. The invention solves the technology problem that the synchronism and power can not be coordinated when the anode bus decreases and rises, and not only reduces the production operation energy consumption, but also has the advantages of operation convenience, effectively increased labor production efficiency in large scale production workshop, and popularization is worthy.

Description

technical field [0001] The invention relates to a method and a device for improving the descending synchronization of single-bus double-anode hoists used in the field of electrolytic aluminum production in which two anode hoists on an electrolytic cell jointly hang an anode bus to work. Background technique [0002] In the field of electrolytic aluminum production, there is a method and a device for simultaneously lifting and lowering an anode busbar by using two anode hoists on an electrolytic cell. When the anode carbon block on the electrolyzer is normally consumed, the anode hoist can automatically lower the anode busbar (the anode carbon block is hung on the anode busbar) to compensate for the normal consumption of the anode carbon block. However, when two anode hoists are used to simultaneously lift and lower an anode busbar, since the two anode hoists work at the same time and are controlled by two different motors, the two anode hoists are When lifting and lowering ...

AI Technical Summary

Problems solved by technology

However, when two anode hoists are used to simultaneously lift and lower an anode busbar, since the two anode hoists work at the same time and are controlled by two different motors, the two anode hoists are When lifting and lowering an anode busbar, since it is difficult for the two motors controlling the two anode hoists to start and shut down synchronously, the two hoists cannot be lifted and lowered synchronously, so that the anode busbar will be very slow when it is lowered. It is easy to tilt and cause the electrolytic surface of the anode carbon block to drop inconsistently, which will cause the current of the electrolytic cell to fluctuate, affect the stability of the voltage, directly cause the energy consumption of the electrolytic cell to be high, and virtually increase the production cost of electrolytic aluminum

However, if only one motor is used to control the two anode hoists, the power when the anode bus is hoisted is difficult to meet

Therefore, when two motors and two anode hoists are used to simultaneously lift and lower an anode busbar, the prior art has not solved the problem of inclination when the anode carbon block descends to the electrolysis surface, so this method and device are still not ideal
