Abstract
The invention relates to an air outlet muffler device for a mute sound box type power station, which comprises a machine body, a shell, an air outlet, a sealing clapboard, an axial fan, an air outlet muffling cavity, a splitting acoustic wall and scoop type muffling walls. The air outlet muffler device is characterized in that the machine body is arranged in the shell, the air outlet of the machine body is isolated through the sealing clapboard, and the axial fan is arranged on the sealing clapboard; meanwhile, the outside of the sealing clapboard is connected with the air outlet muffling cavity; and the front side and two sides of the air outlet muffling cavity are provided with the splitting acoustic wall and the scoop type muffling walls. The air outlet muffler device has the advantages of good ventilation and heat dissipation as well as noise reduction effect, and low cost.
Description
Technical field
The present invention relates to a kind of air-out muffler device for power station, relate in particular to a kind of silencing box type air-out muffler device for power station.
Background technology
The mute chamber type power station is the developing direction of mobile power station, and one of mute chamber type power station key technology is exactly an air-out noise elimination structure designing technique.Existing air-out noise elimination structure method for designing is: air outlet is eliminated the noise by the wind path that the hermetically-sealed construction pipeline forms ventilation and heat.The shortcoming of the method: the one, because air outlet ventilating duct reasons in structure causes mute chamber type power station volume big; For some motors,, adopt the hermetically-sealed construction pipeline often to be difficult to realize especially because its air outlet disperses very much; The 2nd, often back pressure is big when work for air-out ventilating duct structure, and efficient is low, the enforcement not only simple in structure, easy of this device, and reduced the noise that bring in the power station greatly.
Summary of the invention
The object of the present invention is to provide a kind of silencing box type air-out muffler device for power station, this device ventilation and heat, excellent noise reduction effect, and with low cost.
The present invention is achieved like this, it comprises body, shell, air outlet, seal diaphragm, aerofoil fan, air-out noise elimination cavity, splitter acoustic wall, bucket type noise elimination wall, it is characterized in that the body installation in the enclosure, the air outlet of body forms by seal diaphragm isolates, installation shaft flow fan on seal diaphragm, simultaneously connecting air-out noise elimination cavity outside seal diaphragm, is respectively splitter acoustic wall and bucket type noise elimination wall in the front and the both sides of air-out noise elimination cavity.Wind enters the noise elimination cavity, and by splitter acoustic wall sound absorption and to the both sides shunting, the hot blast after the shunting flows out by the shutter that goes out behind the wind scoop noise elimination wall by the casing both sides.
Technique effect of the present invention is: ventilation and heat, and excellent noise reduction effect, and with low cost.

Fig. 2 is plan structure figure of the present invention.
Fig. 3 is left TV structure figure of the present invention.
Body 2, shell 3, air outlet 4, seal diaphragm 5, aerofoil fan 6, air-out noise elimination cavity 7, splitter acoustic wall 8, bucket type noise elimination wall in the drawings, 1,
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, it comprises body 1, shell 2, air outlet 3, seal diaphragm 4, aerofoil fan 5, air-out noise elimination cavity 6, splitter acoustic wall 7, bucket type noise elimination wall 8, it is characterized in that body 1 is installed in the shell 2, the air outlet 3 of body 1 forms by seal diaphragm 4 isolates, installation shaft flow fan 5 on seal diaphragm 4, connecting air-out noise elimination cavity 6 simultaneously outside seal diaphragm 4, is respectively splitter acoustic wall 7 and bucket type noise elimination wall 8 in the front and the both sides of air-out noise elimination cavity 6.Seal diaphragm 1 forms effective isolation with motor, generator air-out radiating area.Then, only need to install the turn of tidal stream fan and form negative pressure on seal diaphragm 1, cooling air is also extracted out by the turn of tidal stream fan through corresponding heat dissipation channel by motor, generator air intake, and the hot blast after the extraction enters air-out noise elimination cavity.Hot air-out enters the noise elimination cavity, and wind enters noise elimination cavity 6, and by 7 sound absorptions of splitter acoustic wall and to the both sides shunting, the hot blast after the shunting is by going out the shutter outflow of wind scoop noise elimination wall 8 backs by the casing both sides.
