To provide a negative pressure prevention chamber that can reliably and stably prevent the inside of a silo from becoming negative pressure.SOLUTION: A negative pressure prevention chamber 1 includes a hollow main body 2 that communicates with an exhaust port provided in a silo installed outdoors and has an opening 2d that opens into the environment, a communication portion 3 whose one end is connected to the exhaust port and whose other end 3b is connected to the main body 2 to communicate the main body 2 with the silo, and an inhibition structure 4 provided inside the main body 2. The inhibition structure 4 includes a partition plate 4A disposed between the communication portion 3 and the opening 2d so as to block the flow of gas inside the main body 2.SELECTED DRAWING: Figure 4
【課題】サイロの内部が負圧になることを確実かつ安定的に防止できる負圧防止チャンバーを提供する。【解決手段】負圧防止チャンバー１は、屋外に設置されるサイロに設けられる排気口と連通するとともに、環境中へ開口する開口部２ｄを備える中空の本体２と、一端が排気口に接続されるとともに、他端３ｂが本体２に接続されて、本体２をサイロと連通させる連通部３と、本体２の内部に設けられる阻害構造４を備え、阻害構造４は、本体２の内部における気体の流れを遮るように、連通部３と、開口部２ｄとの間に配置される仕切板４Ａである。【選択図】図４
