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.

1. A solid-liquid separating apparatus comprising:a strainer that is a cylindrical body formed by a plurality of flat-plate-form circular ring members with gaps in between, said strainer being provided horizontally;a casing with an accommodating section for accommodating therein said strainer, said accommodating section being divided by said strainer into an internal region that is inside said strainer and an external region that is outside said strainer, an intake port that introduces a mixture of solid matter and liquid being formed in said external region, and an outlet port that discharges, to an outside of said casing, liquid that passes between said circular ring members and advances into said internal region being formed in said internal region, anda plurality of scrapers that are provided in said gaps between said circular ring members, said scrapers being moved in relative terms along outer circumferential surfaces of said circular ring members so as to scrape away solid matter adhering to said circular ring members,wherein each of said scrapers is comprised of:a flat-plate-form auxiliary circular ring member having an external diameter that is smaller than external diameter of said circular ring members and is larger than internal diameter of said circular ring members, anda flat-plate-form protruding element extending from an outer circumferential surface of said auxiliary circular ring member, said protruding element being in a same plane as said auxiliary circular ring member, and whereinsaid auxiliary circular ring member is disposed in coaxial with said circular ring members, and said flat-plate-form protruding element has a length that reaches said outer circumferential surfaces of said circular ring members. 2. The solid-liquid separating apparatus according to claim 1, wherein said flat-plate-form protruding element is disposed in plural numbers so as to be lined up in a single row. 3. A solid-liquid separating apparatus comprising:a strainer that is a cylindrical body formed by a plurality of flat-plate-form circular ring members with gaps in between, said strainer being provided horizontally;a casing with an accommodating section for accommodating therein said strainer so that said strainer is rotated, said accommodating section being divided by said strainer into an internal region that is inside said strainer and an atonal region that is outside said strainer, an intake port that introduces a mixture of solid matter and liquid being formed in said external region, and an outlet port that discharges, to an outside of said casing, liquid that passes between said circular ring members and advances into said internal region being formed in said internal region, anda plurality of scrapers provided in said gaps between said circular ring members that form said strainer, said scrapers coming into contact with solid matter adhering to said circular ring members when said strainer is rotated, thus scraping away said solid matter adhering to said circular ring members,wherein each of said scrapers is comprised of:a flat-plate-form auxiliary circular ring member having an external diameter that is smaller than external diameter of said circular ring members and is larger than internal diameter of said circular ring members, anda flat-plate-form protruding element extending from an outer circumferential surface of said auxiliary circular ring member, said protruding element being in a same plane as said auxiliary circular ring member, and whereinsaid auxiliary circular ring member is disposed in coaxial with said circular ring members, and said flat-plate-form protruding element traverses said external region of said casing with a tip end thereof fixed to said casing. 4. The solid-liquid separating device according to claim 1, further comprising axially extending ribs provided on an outer circumference of said circular ring members. 5. The solid-liquid separating device according to claim 3, further comprising axial ly extending ribs provided on an outer circumference of said circular ring members.
