Air intake for vacuum-conveyance waste collection system

摘要

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 pipe 1 including an upper air inflow opening 1 a and a lower air inflow opening 1b to allow outside air to enter; a noise pipe 4 with an upper end inserted under the air inflow pipe 1 and a sound absorption material 4c attached to an inner wall of the noise pipe 4; and a housing 5 including an air suction valve 6 installed inside and a sound absorption material 5a attached to an inner wall of the housing 5, the housing connected to a lower end of the noise pipe 4, to guide the air entered through the air inflow pipe 1 to a waste conveying line 10, 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.
