Environment-friendly filtering device for building water supply and drainage

Abstract

The invention relates to the technical field of building water supply and drainage, and discloses a building water supply and drainage environment-friendly filtering device which comprises a shell, a water inlet pipe is installed at the top of one side of the shell, a connecting pipe is installed at the top of the side, away from the water inlet pipe, of the shell, and a filtering barrel is installed at the end, away from the shell, of the connecting pipe. And a drainage pipe is installed at the bottom of the side, away from the connecting pipe, of the filtering barrel, a filtering plate is rotationally connected into the filtering barrel, and a first rotating shaft is fixedly connected to the bottom of the filtering plate. Particulate matters in wastewater can be effectively separated through a corrugated plate, and the particulate matters are precipitated and flow into a recovery box through the synergistic effect of a lifting block, a baffle plate, a valve I and a valve II, so that centralized treatment is facilitated, and in the process, large particulate matters are effectively removed, and the efficiency of the whole filtering system is also improved; the abrasion of large particles to the filtering material is avoided, so that the maintenance cost is reduced.
