Solid-liquid separating apparatus

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, and
• a 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, and
• a 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 wherein
• said 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.
