Solid-liquid separation system capable of preventing clogging and separating fine particles

摘要

The present invention improves the pore structure of the screen while allowing fine particles with a predetermined particle diameter or less to be easily separated by a helical brush screw having elasticity in the solid-liquid separation process for raw water including sludge. It relates to a solid-liquid separation system capable of preventing clogging and separating fine particles that can prevent clogging, and more particularly, has an internal space formed in a vertical direction, an upper end is opened, and a raw water inlet communicating with the internal space and a separation liquid A solid-liquid separation drum having an outlet respectively formed in the lower part, a plurality of through holes are formed on the outer periphery of the solid-liquid separation drum in a cylindrical shape, and are installed along the longitudinal direction while forming a distance from the inner periphery of the solid-liquid separation drum, and the lower part is in communication with the raw water inlet A solid-liquid separation screen through which sludge is introduced, which is driven to rotate while penetrating the center of the solid-liquid separation screen in the vertical direction, and transports the sludge flowing into the solid-liquid separation screen toward the upper end of the solid-liquid separation drum. and a solid-liquid separator comprising a moving screw for separating and discharging particles and a discharging impeller installed at the open upper end of the solid-liquid separation drum in rotational interlocking with the moving screw and discharging the upwardly transported sludge.
