Abstract:
A solid-liquid separating apparatus comprising:a strainer comprised of a plurality of flat-plate-form circular ring members disposed adjacent to each other with gaps in between, thus being in a cylindrical body; a casing having an accommodating section that accommodates 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, said external region being formed with an intake port that introduces a mixture of solid matter and liquid, and said internal region being formed with an outlet port that discharges to outside said liquid that passes between said circular ring members and advances into said internal region; and a scraper having flat-plate-form protruding elements whose tip ends advance into said gaps between said circular ring members, said scraper moving along outer circumferential surfaces of said circular ring members so as to scrape away said solid matter adhering to said circular ring members; wherein said strainer is comprised of: a pair of end-part circular ring members disposed at both ends of said strainer, a plurality of intermediate circular ring members which are installed between said pair of end-part circular ring members and have inward projections that project from inner circumferential surfaces thereof, a plurality of lateral bridge members installed between said pair of end-part circular ring members, each of said bridge members being formed with a plurality of engaging parts that engage with said inward projections of said intermediate circular ring members and hold said intermediate circular ring members with said gaps in between, said engaging parts being formed a direction perpendicular to an axis of said strainer; and said engaging parts are formed on at least one of a front and a back side of each of said lateral bridge members in a circumferential direction of said strainer, thus being staggered in rows.
