Background technique
Existing silencing apparatus is generally to stop sound transmission and a kind of device of allowing air-flow to pass through, is a kind of important measures of eliminating noise.General mainly formed by the component such as silencing pot, Rectifier plate; Meanwhile, silencing apparatus is also mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment (as blower, air compressor) or in inlet and exhaust system, and silencing apparatus can stop sound wave propagation, allows air-flow to pass through, and is the effective tool of controlling noise.But the problem that silencing apparatus of the prior art exists is: can not effectively reduce the noise that wind speed produces, therefore, be necessary to design a kind of silencing apparatus of new structure.
Although publication number is the Chinese utility model patent of CN 202209201 U, a kind of model muffler that reduces air pertormance noise is disclosed, but the effect that the silencing apparatus of this structure is made an uproar to reduction wind is also not obvious, therefore, be necessary to design a kind of baffler of new structure.
Model utility content
The purpose of this utility model is to provide a kind of silencing apparatus that can effectively reduce the noise that wind speed produces.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind ofly reduce the silencing apparatus that wind is made an uproar, comprise air intake pipe, muffler body and air outlet tube, in described muffler body, be provided with the first dividing plate and second partition, muffler body is divided into the first air chamber successively by described the first dividing plate and second partition, the second air chamber and the 3rd air chamber, between described the first air chamber and the 3rd air chamber, be communicated with hush pipe, between described the 3rd air chamber and the second air chamber, be communicated with ventilation duct, described air outlet tube is communicated with the second air chamber, described air intake pipe is communicated with hush pipe, and air intake pipe is positioned on different axis from hush pipe, in described the second air chamber, a side corresponding with ventilation duct is also provided with the first buffer layer, described a 3rd air chamber side corresponding with hush pipe is also provided with the second buffer layer.
According to a preferred embodiment of the present utility model: described the first buffer layer and the second buffer layer are respectively spongy layer.
According to a preferred embodiment of the present utility model: described hush tube comprises hush tube body and is arranged on the intrinsic waveform passage of hush tube.
According to a preferred embodiment of the present utility model: described ventilation duct, air outlet tube and the hush pipe position on second partition from top to bottom arranges.
Compared with prior art, the beneficial effects of the utility model are: the utility model arranges air intake pipe and the hush pipe of different axis on the one hand, can effectively reduce wind speed and noise, be provided with on the other hand three air chambers and two buffer layers, by the comprehensive function of hush pipe, ventilation duct and air outlet tube, further make air-flow be cushioned, reduce wind speed and wind and make an uproar.
Brief description of the drawings
Fig. 1. the Facad structure figure of the silencing apparatus of making an uproar for reduction wind of the present utility model.
Description of reference numerals: 1, air intake pipe, 2, muffler body, 3, the first air chamber, 4, hush pipe, 5, the first dividing plate, 6, the first buffer layer, 7, the second air chamber, 8, ventilation duct, 9, second partition, 10, the 3rd air chamber, 11, air outlet tube, 12, the second buffer layer.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides a kind of silencing apparatus that wind is made an uproar that reduces, comprise air intake pipe 1, muffler body 2 and air outlet tube 11, in described muffler body 2, be provided with the first dividing plate 5 and second partition 9, muffler body 2 is divided into the first air chamber 3 successively by described the first dividing plate 5 and second partition 9, the second air chamber 7 and the 3rd air chamber 10, between described the first air chamber 3 and the 3rd air chamber 10, be communicated with hush pipe 4, between described the 3rd air chamber 10 and the second air chamber 7, be communicated with ventilation duct 8, described air outlet tube 11 is communicated with the second air chamber 7, described air intake pipe 1 is communicated with hush pipe 4, and air intake pipe 1 is positioned on different axis from hush pipe 4, in described the second air chamber 7, a side corresponding with ventilation duct 8 is also provided with the first buffer layer 6, described the 3rd air chamber 10 side corresponding with hush pipe 4 is also provided with the second buffer layer 12.
The utility model is in the time of work, and air-flow enters by air intake pipe 1, then enters in hush pipe 4, because air intake pipe 1 and hush pipe 4 are positioned on different axis, can make wind speed be reduced, carry out noise reduction by hush pipe 4, reduce wind and made an uproar, then passed in the 3rd air chamber 10, now under the buffer function of the second buffer layer 12, reduce wind speed, wind is entered in the second air chamber 7 by ventilation duct 8 again, same, under the effect of the first buffer layer 6, further reduce wind speed, finally discharged by air outlet tube 11.Make silencing apparatus of the present utility model there is the effect that larger reduction wind is made an uproar.
