Silencer static pressure box

The utility model discloses a silencer plenum chamber which comprises a supporting mechanism used for silencing, an adjusting mechanism used for adjusting the wind direction and an inner supporting mechanism used for installing the adjusting mechanism, the inner supporting mechanism is installed in the supporting mechanism, and the adjusting mechanism is installed on the inner side of the inner supporting mechanism. The power end of the adjusting mechanism is connected with a power mechanism. The adjusting mechanism is matched with the supporting mechanism, internal airflow is adjusted in different states, noise caused by turbulent flow is avoided, and the silencing effect of the sound insulation cotton is improved through the cylindrical structure of the supporting mechanism. 本实用新型公开了一种消声器静压箱，包括用于消音的支撑机构和用于调节风向的调节机构以及用于安装所述调节机构的内支撑机构，所述支撑机构内部安装有所述内支撑机构，所述内支撑机构内侧安装有所述调节机构，所述调节机构动力端连接有动力机构。本实用新型利用调节机构配合支撑机构，利用不同状态，调节内部气流，从而避免乱流产生噪音，利用支撑机构的筒状结构，提高隔音棉的消音效果。
