Description

The present invention relates to a suspended matter removing apparatus and a filtration and circulation system for removing dirt and suspended matter floating in water filled in a pool, a bathtub, and a reservoir.

  Conventionally, as an overflow facility for a bathtub or a pool, a groove forming member having an opening on the upper surface disposed along the upper end portion of the pool side wall and mounted on the upper end portion of the inner side surface of the groove forming member via a lid support portion Disclosed is a drainage ditch provided with a trapezoidal or mesh-shaped lid (see, for example, Patent Document 1). By this drainage groove, most of the overflow water flows along the surface of the water guide plate and is guided from the inner surface to the groove bottom surface.

  Further, as a floating material recovery device, conventionally, a floating material suction means having a downward suction port for sucking a floating material on the water surface by being arranged near the water surface, and a water surface disposed below the suction port. A partition plate for separating the water near the water surface and the water below it so that water not near the suction port is not sucked into the suction port, and acts on the partition plate so that the partition plate is substantially horizontal below the water surface The thing provided with the buoyancy adjustment means for adjusting a buoyancy is disclosed (for example, refer patent document 2). This floating substance recovery device is capable of efficiently sucking floating substances on the water surface while suppressing the suction of water below the water surface to a small amount.
