FOUR-CHANNEL ELECTRODIALYSIS APPARATUS FOR LITHIUM EXTRACTION FROM SALT LAKE
Document Type and Number:
WIPO Patent Application WO/2024/066236
Kind Code:
A1
Abstract:
A four-channel electrodialysis apparatus for lithium extraction from a salt lake, comprising an electrodialysis mechanism (1) and four desalting mechanisms (2). The electrodialysis mechanism (1) comprises a bottom plate (11). Dialysis boxes (13) are fixedly connected to the positions on the top surface of the bottom plate (11) respectively located outside the four desalting mechanisms (2). Ion exchange membranes (15) are fixedly embedded into the inner side walls of the four dialysis boxes (13), respectively. Each desalting mechanism (2) comprises an accommodating housing (22), and the inner side of the accommodating housing (22) adjacent to the ion exchange membrane (15) is provided with a vibration assembly (23). The vibration assembly (23) comprises two rolling wheels (231), two sides of each rolling wheel (231) are each provided with a rotating base (232), a first rotating shaft (239) is rotatably connected between the two rotating bases (232), the first rotating shaft (239) is fixedly connected to the rolling wheel (231), the side of the rolling wheel (231) adjacent to the ion exchange membrane (15) is provided with a ring groove (233), a corrugated block (238) is fixedly connected inside the ring groove (233), an arc block (236) is slidably connected inside the ring groove (233), a vibration rod (234) is fixedly connected to a side surface of the arc block (236), one end of the vibration rod (234) passes through a side wall of the dialysis box (13) and is fixedly connected to a vibration plate (235), a spring (237) is fixedly connected between an inner wall of the dialysis box (13) and the arc block (236), two inner walls of the dialysis box (13) are respectively provided with first sliding grooves (230) at the positions of the two rolling wheels (231), and the rolling wheels (231) are rollably connected to the first sliding grooves (230). A filter screen (21) is fixedly connected to the bottom of the accommodating housing (22).
