Description

Technical Field

[0001] The utility model relates to a feeding system, in particular to a visual feeding device for electrolytic aluminum covering material, belonging to the technical field of secondary safety of operating equipment. Background Art

[0002] At present, almost all electrolytic aluminum production enterprises use pre-baked anodes for production. During the electrolysis process, the anode carbon blocks are continuously consumed. Generally, the anodes need to be replaced after about 30-40 days of use. At this time, the surface shell material on the residual anode is separated and crushed in the anode workshop and returned to the electrolysis workshop to cover the replaced new anode. In this process, since the silo and the conveyor belt are both located on the receiving platform above the ground, and the feed port of the bucket lifting and conveying equipment is located on the roof, the staff cannot timely understand the residual material situation in the silo and the running status of the conveyor belt, which will result in the belt flow rate being too slow to affect the material receiving or the belt flow rate being too fast to cause leakage, which has a great impact on the equipment and the workshop environment; at the same time, when adding materials to the bucket lifting and conveying equipment, since the material bag is in a suspended state, the material bag is prone to shaking when unloading, which causes the material to spill on the ground, and accurate unloading cannot be achieved here.
