SILENCER OF AIR INLET VALVE FOR WASTE COLLECTION SYSTEM

摘要

PURPOSE: A noise suppressor of an air inlet for a vacuum transfer garbage collecting system is provided to prevent sound-absorbing material from being scattered and reduce noise in a high frequency band and a low frequency band. CONSTITUTION: An outer casing(1) comprises an air injection hole(106) which is formed on the lower end to draw in external air. The upper end of an inner casing(2) is inserted into the inside from the lower end of the outer casing. A splitter(3) is installed on the inner center of the inner casing longitudinally with the inner casing. An under casing(4) is installed on the lower end of the inner casing and guides the air flowing from the air injection hole to a garbage conveyance pipe. Sound-absorbing materials are attached to the inner sides of the outer casing, the inner casing, the splitter, and the under casing.
