Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a multi-functional overhead crane feeding control device for aluminum electrolysis. Background technique [0002] It is one of the indispensable and important links in the production of aluminum electrolysis to use the aluminum electrolysis multifunctional crane to add heat preservation material to the newly replaced anode of the electrolytic cell. The silo for storing alumina in the multi-functional crane is designed on the top of the main trolley above the girder of the crane. According to the alumina consumption in the silo, every time the work of replenishing alumina to the silo is 23 hours before the day's night shift. :00, every time the feeding work is carried out, the crane operator needs to move the car to the lower part of the outlet of the alumina silo which is set at a fixed position and is specially used for the feeding of the crane, so the multi-functi...
