ULTRALOW FREQUENCY ATTENUATOR FOR VIBRATING SCREEN DEHYDRATOR

PROBLEM TO BE SOLVED: To completely prevent noise pollution due to vibrating screen dehydrators by causing interference of ultralow frequency sounds among plural vibrating screen dehydrators in opposite phase to each other to attenuate them and furthermore casing interference of ultralow frequency sounds generated from both the ends of connected plural vibrating screen dehydrators in opposite phase with each other by reflecting plates to attenuate them. SOLUTION: Plural vibrating screen dehydrators 5a, 5b, 4c, 5d are arranged side by side, and are connected with unbalance weights each provided on the vibrating screen dehydrators in opposite phase to each other so that ultralow frequencies generated from the vibrating screen dehydrators may be offset. All the plural vibrating screen dehydrators are shielded by an upper reflecting plate 15 and side reflecting plates 16 parallel to each other, allowing ultralow frequency sounds generated from both the ends of the connected plural vibrating screen dehydrators to be attenuated.
