Utility model content：
In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of smoke exhaust fan outlet silencing
Device.
Fire-fighting equipment protector of the present utility model, it includes flue, noise reduction interlayer, assembling pilot pin, filtering
Net, limited post, radome fairing, blast pipe, resonance piece, plate hole, silencing cotton and reflection cavity, flue outer wrap have Silencing clip
Layer, noise reduction interlayer are made up of resonance piece, plate hole, silencing cotton and reflection cavity, and it is fixed that assembling is installed with the side wall of noise reduction interlayer
Position bolt, flue middle is provided with screen pack, is provided with radome fairing between flue and blast pipe, radome fairing with it is spacing
Post is connected.
Preferably, the connected mode of described flue and noise reduction interlayer is nested encryptions, so setting to protect
The bonding strength and tightness degree of flue and noise reduction interlayer are demonstrate,proved, while discharging flue gas by flue, by Silencing clip
Vibrations and noise of the layer to flue carry out noise reduction process.
Preferably, described reflection cavity outer wrap has silencing cotton, so setting can enter while reducing and shaking
Row noise elimination is handled, and improves the efficiency of noise elimination noise reduction, is also allowed for changing silencing cotton, is ensured soundproof effect.
Preferably, described flue and the connected mode of radome fairing are assembly connection, so setting to pass through
The flowing of flue gas, makes an uproar so as to be rubbed when reducing flue gas discharge with flue caused by vibrations during radome fairing adjustment discharge flue gas
Sound.
Preferably, the material of described silencing cotton is polyester fiber, fire resisting of silencing cotton etc. can be improved by so setting
Level, in the scene of a fire can also normal work, improve service life of the present utility model.
The beneficial effects of the utility model：The fire-fighting equipment can be arranged effectively fire-fighting by noise reduction interlayer and radome fairing
Cigarette blower fan carries out noise reduction, damping processing, so as to reduce the operating noise of smoke exhaust fan, reduces noise pollution, while this reality
With new structure it is simple, be conveniently replaceable silencing cotton, safeguard and easy to use, refractory ability is strong, service life length, can drop
Low noise reduction cost.
Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.

Embodiment：
As depicted in figs. 1 and 2, present embodiment uses following technical scheme：It includes flue 1, Silencing clip
Layer 2, assembling pilot pin 3, screen pack 4, limited post 5, radome fairing 6, blast pipe 7, resonance piece 201, plate hole 202, the and of silencing cotton 203
Reflection cavity 204, the outer wrap of flue 1 have noise reduction interlayer 2, and noise reduction interlayer 2 is by resonance piece 201, plate hole 202, silencing cotton 203
Formed with reflection cavity 204, assembling pilot pin 3 is installed with the side wall of noise reduction interlayer 2, the middle of flue 1 is provided with
Screen pack 4, is provided with radome fairing 6 between flue 1 and blast pipe 7, radome fairing 6 is connected with limited post 5.
Wherein, the connected mode of described flue 1 and noise reduction interlayer 2 is nested encryptions, and so setting to ensure
The bonding strength and tightness degree of flue 1 and noise reduction interlayer 2, while discharging flue gas by flue 1, by Silencing clip
The vibrations of 2 pairs of flue 1 of layer and noise carry out noise reduction process；The described outer wrap of reflection cavity 204 has silencing cotton 203, this
Sample, which is set, to carry out noise elimination processing while reducing and shaking, and improve the efficiency of noise elimination noise reduction, also allow for changing silencing cotton
203, ensure soundproof effect；The connected mode of described flue 1 and radome fairing 6 is assembly connection, and so setting to lead to
The flowing of flue gas during the adjustment discharge flue gas of over commutation cover 6, so as to be rubbed when reducing flue gas discharge with flue 1 caused by vibrations
