Abstract
A solid-liquid separating apparatus comprising a cylindrical strainer formed by circular ring members with gaps in between, a casing having the strainer therein, and scrapers disposed in the respective gaps between the circular ring members for removing solid matter adhering to the end (flat) surfaces of the circular ring members. Each of the scrapers comprises a flat auxiliary circular ring member and a flat protruding element. The external diameter of the auxiliary circular ring member is smaller than the external diameter of the circular ring members and is larger than the internal diameter of the circular ring members, and the protruding element extends from the outer circumferential surface of the auxiliary circular ring member. The auxiliary circular ring members are disposed coaxially with the circular ring members, and the tip ends of protruding elements reach the outer circumferences of the circular ring members.
