PLANT FOR EXTRACTION OF SUBSTANCES AND PARTICLES FROM SUSPENSIONS AND SOLUTIONS Russian patent published in 1997 - IPC

FIELD: equipment and process of extraction of particles from disperse systems, applicable for mining of gold and metals and their oxides, for extraction of protein substances, for water purification and disinfection. SUBSTANCE: the plant uses cored insulated electrodes connected to a voltage source and placed in a casing furnished with inlet and drain holes. The plant is furnished with three cylindrical drums installed concentrically in the casing one in another, two of the drums (internal metal and middle dielectric) are fixed, and the external dielectric drum is installed for rotation. The cored electrodes are positioned in the walls of the fixed dielectric drum on its circumference generating line. The drum proper is installed in the casing in such a manner that the electrodes are arranged from the axis of the inlet hole to the edge of the passage for discharge of the extracted material, with a scraper installed above it. The voltage source is installed inside the metal drum. EFFECT: enhanced efficiency. 2 dwg
