Abstract

The present application relates to a filtering device for electrolyte materials and a filtering method thereof, the filtering device includes a filtering assembly, the number of which is at least one, and is used for multi-stage filtration of the material to be filtered; the structure of the filtering assembly includes a shell; a drum; a filter plate, which is annular in structure, which is arranged to extend radially inward from the lower part of the drum, and is used for primary filtration of the material to be filtered; a guide table, which is used to guide the material to be filtered to the annular filter plate; a filter cartridge, which is detachably fixed to the lower end of the drum, and performs secondary filtration of the material to be filtered under the action of centrifugal force. The present invention has a compact and reasonable structure and is easy to operate. By adopting a multi-stage filtration strategy, efficient and accurate filtration of electrolyte materials is achieved. The slope design of the drum and the filter cartridge and the periodic frequency conversion control enable the material to be filtered to be evenly distributed and effectively moved under the action of centrifugal force, which increases the contact opportunity between the material and the filter medium and improves the filtration efficiency.
