Description

Technical Field

[0001] The utility model relates to the technical field of magnesium electrolysis production, in particular to a vacuum system filtering device for a magnesium electrolytic cell. Background Art

[0002] In the process of magnesium electrolysis production, the produced liquid magnesium needs to be regularly extracted from the magnesium collecting chamber by vacuum. After the liquid magnesium is extracted, molten magnesium chloride needs to be added. In the process, a vacuum system is also needed to break the siphon and control the amount of feeding. Since the vacuum system is a vital equipment in the process of magnesium electrolysis production, it inhales a lot of dust during the process of extracting magnesium and adding materials. Therefore, a filter needs to be added at its inlet to reduce or avoid the inhalation of dust and particulate matter into the vacuum system pipeline and vacuum pump, causing pipeline blockage or pump damage.
