Furthermore, the four spoilers are arranged on the upper side and the lower side of the inner wall of the silencing pipe in a pairwise equidistant and staggered manner.
Further, a curtain wall shutter is fixedly installed at an opening on the left side of the air outlet through a bolt.
The utility model has the beneficial effects that:
the automatic fire-proof valve is arranged at the front end of the exhaust fan, the valve switching signal is connected with the fire alarm system, and when a fire occurs, the valve is closed, so that convection is avoided.
According to the utility model, the damping shock absorber is arranged between the bottom of the exhaust fan and the structural support, so that the vibration can be effectively prevented from being transmitted to the floor slab when the fan runs.
The exhaust fan is connected with the noise eliminator through the guide cylinder, so that the change of the air flow structure is mild, and the surge of the fan is effectively inhibited.
According to the utility model, the coarse filter screen is arranged at the air outlet of the outer discharge port of the silencer, so that industrial dust is effectively filtered, and the environment pollution is avoided.
The coarse filter screen adopts a prefabricated structure, and is convenient to clean and replace at regular intervals.
The structure device of the utility model is suitable for noise reduction of the exhaust fan and is also suitable for noise reduction of the blower.
