Background technique
Develop rapidly along with national economy, there is already earth-shaking variation in people's life, compact car is ridden instead of walk becomes a kind of normality in urban, increasing automobile shuttles back and forth in streets and lanes, be seen everywhere, yet, the thing followed is that various noisy sound mingles, and these noises have had a strong impact on modern daily life and office efficiency, be in for a long time in the animation of this high-decibel noise, health also can be subject to infringement in various degree, had a strong impact on modern people's healthy and daily life, therefore, the noise that how to reduce automobile generation becomes current problem demanding prompt solution.
In prior art, exist some to take the muffling device that noise-decreasing is object, but these muffling devices are generally manufactured all more complicated, fabricating cost is high, spatial volume is huge, be applied in and on automobile, still have a lot of deficiencies, and on automobile, produce the outlet pipe that position that noise is maximum is motor place, general processing method can be arranged on muffling device outlet pipe place, but, current muffling device for outlet pipe except the effect of making an uproar still undesirable, noise reduction is still not thorough, can only carry out noise reduction to single frequency noise, or can only work to the frequency noise of narrow-band, erasure effect is low, do not reach modern desired level, therefore, be necessary its structure study further and improve, to meet modern people's life requirement and the protection needs to environment.
Model utility content
For solving above technical problem, the technical solution of the utility model is for providing a kind of outlet pipe baffler, this baffler can be installed on the outlet pipe place on automobile, the noise that motor car engine can be sent is processed, prevent that noise is diffused into around, to reach the object of noise abatement, environmental protection, for wide band frequency noise, can both effectively eliminate, noise reduction is thorough, has greatly improved noise reduction, and erasure effect is obvious.
The technical solution of the utility model is:
A kind of outlet pipe baffler, comprise the tubular shell being surrounded by hollow cavity, in described hollow cavity, be filled with sound absorbing material, in described tubular shell, be furnished with successively vertically a plurality of anechoic chambers, described a plurality of anechoic chamber is separated by a plurality of noise reduction cores of laterally arranging, described tubular shell one side is provided with suction port, opposite side is provided with air outlet, in described tubular shell, from suction port to air outlet, be axially provided with a noise reduction core that runs through each anechoic chamber, described noise reduction core is arranged with micropore hush pipe outward, between the described noise reduction outer core that runs through tubular shell and described micropore hush pipe inwall, be laid with the microwell plate of some parallel arrangements, microwell plate in described micropore hush pipe is arranged along the radial dispersion of described micropore hush pipe, in described each anechoic chamber, be vertically arranged with the microwell plate of a plurality of parallel arrangements, gap between described adjacent microwell plate forms sound resonance chamber.
Further, described tubular shell both sides are respectively equipped with connecting flange, and described tubular shell and described connecting flange are fastenedly connected by clamping bolt.
Further, described tubular shell outer race is provided with some equally distributed micropore noise reduction circles.
The beneficial effects of the utility model: the outlet pipe baffler that the utility model provides, can be installed on the outlet pipe place on automobile, the noise that motor car engine can be sent is processed, around preventing that noise is diffused into, to reach the object of noise abatement, environmental protection, for wide band frequency noise, can both effectively eliminate, noise reduction is thorough, greatly improved noise reduction, erasure effect is obvious.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the present embodiment.
Reference character: 1, tubular shell, 2, sound absorbing material, 3, connecting flange, 4, clamping bolt, 5, suction port, 6, air outlet, 7, anechoic chamber, 8, noise reduction core, 9, micropore hush pipe, 10, microwell plate.
Embodiment
For making the utility model embodiment's object, technological scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with a kind of outlet pipe baffler shown in Fig. 1, it is characterized in that, comprise the tubular shell 1 being surrounded by hollow cavity, in hollow cavity, be filled with sound absorbing material 2, in tubular shell 1, be furnished with successively vertically a plurality of anechoic chambers 7, a plurality of anechoic chambers 7 are separated by the noise reduction core 8 of a plurality of parallel arrangements of cross setting, tubular shell 1 one sides are provided with suction port 5, opposite side is provided with air outlet 6, in tubular shell 1, from suction port 5 to air outlet, 6 be axially provided with a noise reduction core 8 that runs through each anechoic chamber 7, the outer micropore hush pipe 9 that is arranged with of noise reduction core 8, run through the microwell plate 10 that is laid with some parallel arrangements between noise reduction core 8 outer walls of tubular shell 1 and micropore hush pipe 9 inwalls, microwell plate 10 in micropore hush pipe 9 is arranged along the radial dispersion of micropore hush pipe 9, in each anechoic chamber 7, be vertically arranged with the microwell plate 10 of a plurality of parallel arrangements, gap between adjacent microwell plate 10 forms sound resonance chamber.
