In addition, the inner wall of the conical exhaust plate is not easy to accumulate dust, preventing dust accumulation from affecting the exhaust effect;

[0025] (4) The dust collecting tray can collect the dust falling from the first opening. In this way, the silo quick exhaust device of the present invention can not only realize the function of quick exhaust and prevent dust from being ejected into the air with the airflow, but also collect the leaked dust to prevent the dust from falling on the top of the silo. When cleaning, it is only necessary to disassemble the silo quick exhaust device for cleaning, without the need for workers to frequently climb above the silo to clean the dust on the upper surface of the silo, thereby reducing safety hazards;

[0026] (5) The clamp-type blind plate is processed as the base of the outer cover, and a limit buckle is welded on the lower side of the clamp-type blind plate, which can realize the rapid installation and removal of the filter element and the rapid installation and removal function of the entire exhaust device;
