Abstract

The utility model discloses a filter separating device for filtering and coarse graining. At least one filter separating component is arranged in a tank, and is provided with a porous outer cylinder (12) and a central tube (11). The upper end of a fiber (15) between the porous outer cylinder (12) and the central tube (11) is fixed to a movable plate (13), and the lower part is fixed to a still plate (10). A cylinder surface for slide fit of the movable plate and the central tube is provided with a spiral guide slot and a key. The upper part of a sleeve (13) fixedly connected with the movable plate is connected with a pressure disc (21) via a bearing (22).
