Description
[technical field]
The utility model is about a kind of silencing apparatus.
[background technique]
Existing silencing apparatus general sound-absorbing porous material reduces noise.Arrange in the duct on inwall sound-absorbing material being fixed on air-flow path or according to certain way, just constitute resistive muffler.When sound wave enters resistive muffler, a part of acoustic energy rubs and changes into thermal energy consumption and dissipates in the hole of porous material, makes to be weakened by the sound wave of baffler.
But this silencing apparatus soundproof effect is unsatisfactory, its structure only has one to connect mouth, then puts the cover of a muffler material manufacture, and so not only soundproof effect is bad, and its durability is also poor, within have more than is needed two months, substantially just scraps.Particularly be used in the silencing apparatus on air twitch valve, be not more durable.
The utility model is made for when this kind of mould.
[model utility content]
The purpose of this utility model overcomes the deficiencies in the prior art and provides a kind of soundproof effect good, durable silencing apparatus.
For above-mentioned purpose, the utility model by the following technical solutions:
A kind of silencing apparatus, it is characterized in that including closed shell 1, shell 1 is provided with at least one suction port 2 and the outfall 3 being located at suction port 2 lower end, an inner bag 4 for buffering air pressure is at least set in shell 1, the wall of inner bag 4 is provided with multiple through hole 5, in inner bag 4, be provided with elementary hush tube 6, elementary hush tube 6 one end is connected with suction port 2, and the wall of described elementary hush tube 6 spreads all over elementary small sound attenuation hole 7.
A kind of silencing apparatus as above, it is characterized in that described elementary hush tube 6 is in spring-like, described elementary small sound attenuation hole 7 is located on the tube wall of volute.
A kind of silencing apparatus as above, it is characterized in that described inner bag 4 is two, be divided into large inner bag 41 and small inner container 42, described through hole 5 is distributed on the surface of large inner bag 41 and small inner container 42.
A kind of silencing apparatus as above, is characterized in that in the bottom surface of described large inner bag 41 and small inner container 42 be barrel-shaped.
A kind of silencing apparatus as above, is characterized in that described elementary hush tube 6 forms for metal or plastic material manufacture.
A kind of silencing apparatus as above, is characterized in that described inner bag 4 is plastic cement material or metal material.
A kind of silencing apparatus as above, is characterized in that being provided with drain valve 8 on outfall 3.
A kind of silencing apparatus as above, is characterized in that described inner bag 4 is three.
A kind of silencing apparatus as above, is characterized in that the general 0.01-0.5mm in aperture of described elementary small sound attenuation hole 7.
The beneficial effects of the utility model have:
The utility model utilizes an elementary hush tube and inner bag and a shell, pressurized gas is after elementary hush tube, and by the elementary small sound attenuation hole of elementary hush tube, pressurized gas then reduce to low pressure rapidly, afterwards again through inner bag, make gas substantially can not send ear-piercing sound.
Secondly, two inner bags are set, make its soundproof effect better.

[embodiment]
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated:
As shown in the figure, a kind of silencing apparatus, includes closed shell 1, and shell 1 is provided with at least one suction port 2 and the outfall 3 being located at suction port 2 lower end.In shell 1, at least arrange an inner bag 4 for buffering air pressure, the wall of inner bag 4 is provided with multiple through hole 5, the large I of this through hole 5 is implemented according to the size of the size of air displacement and silencing apparatus.In inner bag 4, be provided with elementary hush tube 6, elementary hush tube 6 one end is connected with suction port 2, and the wall of described elementary hush tube 6 spreads all over elementary small sound attenuation hole 7.In use, first dress needs the tracheae of eliminating the noise to receive on elementary hush tube 6, after pressurized gas one enter into elementary hush tube 6, pressurized gas are then rapid to be sprayed from elementary small sound attenuation hole 7, pressurized gas spread rapidly, then reduce to low pressure rapidly, and its noise sent greatly weakens, again carry out noise elimination pressure release through inner bag 4 more afterwards, make gas substantially can not send ear-piercing sound.Described suction port 2 can have multiple, and multiple tracheae of eliminating the noise that needs all can be inserted into suction port 2, and each suction port 2 is connected on elementary hush tube 6 after can pooling together.
Furthermore, described elementary hush tube 6 is in spring-like, and described elementary small sound attenuation hole 7 is located on the tube wall of volute.Be set to volute, the flow direction of gas produced and turns to, better effect is played to noise elimination.Outfall 3 is provided with drain valve 8.Drain valve 8 can be exhaust shutter.
Further, described inner bag 4 is two, is divided into large inner bag 41 and small inner container 42, and described through hole 5 is distributed on the surface of large inner bag 41 and small inner container 42.The large I of this through hole 5 is implemented according to the size of the size of air displacement and silencing apparatus, and the through hole such as on large inner bag 41 can be established a little louder, and the through hole on small inner container 42 can establish point.So prior effect is played to soundproof effect.Certainly, inner bag 4 can arrange three, even can arrange four, and its soundproof effect is very good, and shown in figure is employing two inner bags.After elementary hush tube 6 extends through each inner bag 4 successively, then be connected with the suction port 2 on shell 1.The general 0.01-0.5mm in aperture of described elementary small sound attenuation hole 7.This scope is taked in its aperture, can reach soundproof effect well, can reduce pressure well again.
In addition, be barrel-shaped in the bottom surface of described large inner bag 41 and small inner container 42.This structure is also to make air-flow more smooth and easy.
Further, described elementary hush tube 6 forms for metal or plastic material manufacture.Described inner bag 4 is plastic cement material or metal material.
