Abstract
Disclosed is a centrifugal filtration apparatus including a casing, a shaft, a stand tube, a rotor, and a stereoscopic filter. The shaft is vertically installed in the casing and guides a fluid to an upper end of the casing. The stand tube rotates about the shaft and sprays the fluid to the upper end of the casing. The rotor rotates along with the stand tube and forms a space in the casing to receive and filter the fluid sprayed from the stand tube. The stereoscopic filter includes a plate member and wire members. The plate member is rolled up around the stand tube and is installed in the rotor. The wire member is installed between layers of the plate member to secure a gap between the layers of the plate member and forms a filter layer to filter the fluid that flows between the layers of the plate member.
