CHUTE MEANS FOR REFUSE IN SUCTION OPERATED REFUSE COLLECTING SYSTEM

摘要

A flapping device for a volume type inlet of a waste collection system of a building is provided to secure strong supporting force for holding waste by a predetermined volume by a multi-shaft hinge part, and manage the volume of the waste uniformly for minimizing the pressure loss of air inhaled via a chute. A flapping device for a volume type inlet of a waste collection system of a building includes a disposal pipe(31) communicated with a waste chute(20) and formed with a space inside, a first flap panel(101) fixed at an upper part of an end of the inner space of the disposal pipe, and a second flap panel(103) coupled with the first one by a first hinge part(H1).
