The invention relates to a wheel disk type liquid-liquid extraction tower, which comprises a first clarification section, an extraction section, a second clarification section, a powder device and a main shaft. The extraction section is positioned between the first clarification section and the second clarification section. The upper end of the main shaft is connected with a power output shaft of the power device. The lower end of the main shaft penetrates through the first clarification section, extends into a cavity of the extraction section, and is installed on a support seat arranged on the bottom of the extraction section. The extraction section comprises at least two extraction chambers, wherein a housing of the extraction section and two annular horizontal separation plates arranged on the inner wall of the housing close to form the extraction chambers, and a wheel disk is arranged inside each extraction chamber, and is arranged on the main shaft. The housing wall of the first clarification section is provided with a material liquid inlet and an extraction liquid outlet. The housing wall of the second clarification section is provided with an extraction agent inlet and an extraction residue liquid outlet.
