[0002] In the aluminum electrolysis production process, alumina and aluminum fluoride are transported to the upper hopper of the electrolytic cell via a feeding chute, and then fed into the electrolytic cell by a constant-volume feeder. However, when the cylinder of the constant-volume feeder malfunctions, the following technical challenges arise: First, the alumina or aluminum fluoride in the hopper needs to be placed into the electrolytic cell, resulting in waste of alumina and aluminum fluoride. Second, the constant-volume feeder needs to be lifted out entirely by an overhead crane for repair and replacement, posing a risk of lifting operations. In addition, the continuous high temperature environment above the cell exposes workers to the risk of heatstroke, affecting occupational health and increasing safety hazards.

[0003] Specifically, a 500KA electrolytic cell constant-volume feeder is needed that eliminates the need to empty the hopper and disassemble the entire feeder when the cylinder fails. This not only reduces material loss of alumina and aluminum fluoride, but also significantly lowers maintenance costs and improves operational safety. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a 500KA electrolytic cell constant-volume feeder that eliminates the need to empty the material hopper and disassemble the entire feeder when the cylinder is damaged. This not only reduces material loss of alumina and aluminum fluoride, but also significantly lowers maintenance costs and improves operational safety; thus overcoming the shortcomings of existing technologies.

[0005] The objective of this utility model is achieved through the following technical solution: This utility model discloses a 500KA electrolytic cell constant volume feeder, which includes a guide cylinder, a constant volume device at the lower end of the guide cylinder, and a feed inlet communicating with the constant volume device at the lower part of the guide cylinder.
