Abstract
The invention belongs to an efficient and cheap silencing material, named as a metal wire. For knocking noise generated when waste gas is exhausted by a high-pressure air source, a conventional silencer mostly adopts shunting pipes and microporous acoustic panels, but cannot achieve an ideal effect on the change of the airflow condition and the acoustic frequency spectrum, and is complex in process, high in cost, heavy in weight, and difficult to maintain. According to the invention, the metal wires, which are rolled into a mass naturally in cutting, serve as unique fillers of an exhaust pipe and an expanding chamber, owns various functions of all traditional silencers, and not only is low in cost and maintenance-free, but also is extremely remarkable in silencing effect. The silencing material which is light in weight and efficient can be used for aeomotors.
Description
Invention field
The invention belongs to a kind of efficient muffler material, it causes the venting gas appliance of pinking for filling high-pressure air source release waste gas.
Background technique
Pressurized gas can cause pinking when sudden outburst, form noise pollution.
Conventional muffler adopts impedance, interference, absorption etc. means more, at expansion chamber, many staggered ram's hornss and some bafflers is set, complex process, and cost is high, and to the change of air-flow and sound wave, effect is also not obvious.
Summary of the invention
The present invention adopts in cutting process processed naturally curling agglomerating wire (being similar to the household cleaning ball) as the only packing of outlet pipe and expansion chamber, it both can allow pressurized gas discharge smoothly, do not cause again simultaneously the formation of gas shock wave, thereby all functions that have traditional sound-absorbing material, complicated muffling unit must be set, need not safeguard throughout one's life.
But theory of the present invention is not to go later to go out it at the formation of noise, and is to get on to stop from the source formation of noise.
Filled up curling unordered wire due to outlet pipe and expansion chamber, high pressure exhaust gas can't directly enter atmosphere, and acoustic energy is changed into heat energy to greatest extent, so have the function of traditional dissipative muffler.
Because wire has good elasticity, can effectively absorb the energy of high pressure exhaust gas, make rapidly waste gas decompression, reduce flow velocity, unlikelyly cause the air vibrations, therefore, the present invention has again the function of traditional reactive muffler.
Based on above-mentioned 2 points, the present invention has the function of traditional impedance complex formula silencing apparatus beyond suspicion.
Because the agglomerating wire through mild compression can be divided into countless trickle tributaries to the waste gas streams of high pressure, these trickle air-flows have obtained fully cooling and decompression when flowing into atmosphere through incomparable tortuous passage, the audible sound composition of noise spectrum exhausts, sound wave is subject to stack, interferes, reflects, filters, make acoustic pressure, the phase place of noise occur repeatedly weaken and change, so that soundproof effect of the present invention is traditional vortex type silencer is incomparable.
Because the present invention is light, efficient, therefore can be used for eliminating the noise that the airplane engine exhaust produces.
The present invention is without accompanying drawing.
Mode of execution
Be advisable with flat in transverse section wiry, wide 1 millimeter, thick 0.1 millimeter.Agglomerating wire is directly filled in outlet pipe and expansion chamber.Unimpeded for exhaust, should not fill in to get tension.
According to this pattern, also can adopt lightweight and resistant to elevated temperatures foamed ceramic particle to make the packing of outlet pipe, this many micropores spherical ceramic particles diameter 5---10 millimeters.
Claims (2)
1. efficient, light muffler material, it becomes flat filament to make by tungsten, stainless steel etc. refractory metal through cutting, and this naturally curling agglomerating wire is wide 1 millimeter, thick 0.1 millimeter.
2. muffler material as claimed in claim 1, also can adopt light-weight foam spheric granules pottery, this multi-microporous ceramic bulb diameter 5---10 millimeters.
