Air intake for vacuum-conveyance waste collection system

Abstract

There is provided an air intake for a vacuum-conveyance waste collection system, to form a high-speed air flow by allowing air to enter a conveying line through which waste being put into a waste receiving device is conveyed to a central waste collection station. The air intake for the vacuum-conveyance waste collection system according to the present invention comprises: an air inflow pipeincluding an upper air inflow openingand a lower air inflow openingto allow outside air to enter; a noise pipewith an upper end inserted under the air inflow pipeand a sound absorption materialattached to an inner wall of the noise pipe; and a housingincluding an air suction valveinstalled inside and a sound absorption materialattached to an inner wall of the housing, the housing connected to a lower end of the noise pipe, to guide the air entered through the air inflow pipeto a waste conveying line, wherein un upper rain cap in a cone shape is installed at an upper position in the air inflow pipe, a mesh is installed at the upper end of the noise pipe, and a lower rain cap in a frustum shape including a central through-hole is installed between the upper rain cap and the mesh.
