For material to form taper silencing channel, resistive sound absorber, the resistive sound absorption dress is axially arranged in the silencing pot lumen centers
It sets the sound-absorbing material shunk including taper and bores stick, taper silencing channel is separated into streamlined branch and disappeared by the sound-absorbing material cone stick
Sound channel, due to serving as a contrast the sound-absorbing material of patch mineral wool in channel, due to channel cross-sectional area longer dimension, the shorter high frequency of wavelength is made an uproar
Sound is passed through with narrow beam shape, it is difficult to and sound-absorbing material is in contact and radiates, and reduces acoustic attenuation performance, in response to this,
Be additionally arranged resistive absorbent treatment in the channel, and be made into it is streamlined, not only can absorption and reflection to high frequency, but also can reduce
Drag losses, to preferably inhibit noise.
2, this patent includes mineral wool using the sound-absorbing material, due to mineral wool, one kind of mineral wool, by steel blast furnace
Staple fiber made of slag slag, common raw material have the slags such as iron, phosphorus, nickel, lead, chromium, copper, manganese, zinc, titanium, it is also possible to iron packaging
Material by blast-furnace cinder or Copper Slag, aluminium ore slag etc. is primary raw material since mineral wool is using industrial waste slag, through molten
Change, using staple shape inorfil made of the techniques such as supercentrifugal process or blowing process, it has, and light, thermal coefficient is small, no
Burning, the features such as mothproof, inexpensive, corrosion-resistant, chemical stability is good, sound absorbing performance is good can be used for the filling insulation of building, inhale
Sound, sound insulation, oxygenerator and freezer cold insulation and various heat power equipments are stuffed heat insulated etc., are mainly used as building materials and sound absorber
Material.
3, this patent is axially fixed at silencing pot lumen centers axis, the suction through bracket using sound-absorbing material cone stick
Sound material bores stick inner surface adhering glass silk cloth, and another side is bonded in the external peripheral surface of cone stick perforation grillage, using sound absorption
Material bores stick, its inner cavity is not only divided into streamlined, while by bonding glass wool cloth, improving the effect of sound-absorbing.
4, this patent is fixed on inner cavity by cone stick perforation grillage, ensure that the fixed intensity of cone stick perforation grillage.
