Abstract
A kind of multitube intake muffler, silencer include air inlet, gas outlet and noise elimination cavity；Air inlet includes multiple air inlet pipe, and air inlet pipe inwardly gradually tapers up greatly for the air inlet caliber of bell mouth shape and air inlet pipe, and each air inlet pipe is in circle arrangement centered on silencer central axis；Each air inlet pipe, which corresponds to, to be stretched into a noise elimination cavity；The inner side of noise elimination cavity has noise elimination adsorption layer, and the cavity wall between noise elimination cavity and gas outlet is equipped with filter layer.The intake muffler filters sponge by setting, and adds the function of air filtration.The design of noise elimination cavity, which then employs the sponge that surface is wave crest shape, can improve acoustic absorptivity and absorption area, enhance the sound absorption efficiency of noise elimination cavity.Pass through the design of the small horn mouth formula air inlet pipe of the semiclosed outer imperial palace of air inlet, so that the noise to shed from machine inlet will not be dispersed into outside silencer easily, but fully absorbed after more secondary reflections by noise elimination cavity, just distribute, it is this to design the noise reduction capability for being effectively improved silencer.
Description
Technical field
Silencer technical field is the utility model is related to, more particularly to a kind of multitube intake muffler.
Background technology
The intake muffler is a kind of silencer at the air inlet position for the machine for being used to convey air dielectric.It is suitable for
The form of direct air-breathing from air.
The machine of air is conveyed, when the direct air-breathing from air, noise caused by machine, will necessarily pass through machine
The air inlet of device is outwards propagated, and if the air inlet of machine does not take noise reduction measure, its noise necessarily affects the ring of surrounding
Border.Under normal circumstances, machine is required for installing import silencer additional, meanwhile, in order to meet that machine in itself wants air purity
Ask, generally also need to install air filter additional.
Utility model content
To overcome problems of the prior art, the utility model provides a kind of multitube intake muffler.
The technical scheme in the invention for solving the technical problem is：This kind of multitube intake muffler, silencer
Including air inlet, gas outlet and noise elimination cavity；Air inlet includes multiple air inlet pipe, and air inlet pipe is the air inlet of bell mouth shape and air inlet pipe
Mouth caliber inwardly gradually tapers up greatly, and each air inlet pipe is in circle arrangement centered on silencer central axis；Each air inlet pipe corresponds to
Stretch into a noise elimination cavity；The inner side of noise elimination cavity has noise elimination adsorption layer, and the cavity wall between noise elimination cavity and gas outlet was equipped with
Filtering layer.
Further, the air inlet pipe extends to 1/5th of noise elimination cavity height into noise elimination cavity to a quarter position
Put.
Further, the noise elimination adsorption layer is noise elimination sponge.
Further, the surface of the noise elimination sponge is wave crest shape.
Further, the filter layer is filtering sponge.
To sum up, the above-mentioned technical proposal of the utility model has the beneficial effect that：
The intake muffler filters sponge by setting, and adds the function of air filtration.
The design of noise elimination cavity, which then employs the sponge that surface is wave crest shape, can improve acoustic absorptivity and absorption area, enhance
The sound absorption efficiency of noise elimination cavity.
Pass through the design of the small horn mouth formula air inlet pipe of the semiclosed outer imperial palace of air inlet so that shed from machine inlet
Noise will not be dispersed into outside silencer easily, but is being fully absorbed after more secondary reflections by noise elimination cavity, just given out
Go, it is this to design the noise reduction capability for being effectively improved silencer.The intake muffler is that one kind collects noise elimination, filtering function in one
The import silencer of body.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：
1 air inlet, 2 gas outlets, 3 noise elimination cavities, 4 air inlet pipe, 5 noise elimination sponges, 6 filtering sponges.
Embodiment
The feature and principle of the utility model are described in detail below in conjunction with attached drawing 1, illustrated embodiment is only used for solving
The utility model is released, the scope of protection of the utility model is not limited with this.
As shown in Figure 1, the utility model silencer includes air inlet 1, gas outlet 2 and noise elimination cavity 3.Air inlet 1 includes more
A air inlet pipe 4, air inlet pipe 4 inwardly gradually taper up greatly for the air inlet caliber of bell mouth shape and air inlet pipe, and each air inlet pipe is to eliminate the noise
It is in circle arrangement centered on device central axis.Each air inlet pipe, which corresponds to, to be stretched into a noise elimination cavity 3, and air inlet pipe is prolonged into noise elimination cavity
1/5th of noise elimination cavity height are extended to a quarter position.After ensureing that noise eliminates as far as possible in noise elimination cavity, then dissipate
It is dealt into air.The noise elimination cavity and the direct unicom of air inlet of usual intake muffler, are so possible to noise absorbent can be made not fill
Point, and be dispersed into air.The air inlet design of the intake muffler employs the form of air inlet pipe, remaining space-closed, makes an uproar
Sound only can just be distributed by air inlet pipe, and the bore of single air inlet pipe is smaller compared with the space proportion of noise elimination cavity, therefore be made an uproar
Sound, which can pass through more reflection, to be dispersed into by air inlet pipe in air, order of reflection increase, it is meant that noise elimination effect
Enhancing, therefore, the noise elimination effect being designed with beneficial to enhancing silencer of air inlet pipe.
The inner side of noise elimination cavity has noise elimination adsorption layer, and the cavity wall between noise elimination cavity and gas outlet is equipped with filter layer, filtering
Layer can use filtering sponge 6.The design of noise elimination cavity, is for eliminating the noise propagated from from machine entrance.Noise passes through
Filtering sponge, enters gas outlet.The effect of filtering sponge be exactly for debris in air filtering.Machine is directly from air
Middle air-breathing, and air is an open space, wherein grass cuttings of often wafting, paper scrap, tiny feather etc., these are to conveying air
Machine be harmful, the tiny micropore for filtering sponge ensures that the air of cleaning is entered in machine, these are harmful
Object be then blocked in outside sponge.As long as timing cleaning debris, it is possible to ensure the smooth of machine air inlet.Noise elimination cavity outermost layer
Be steel plate, play the role of certain sound insulation, the adsorption layer of attachment absorption sound on the inside of steel plate, can specifically use surface for
The noise elimination sponge 5 of wave crest shape.Not only acoustic absorptivity is higher for the sponge of wave crest shape, its unique convex-concave surface also increases sound absorption face
Product, has noise and absorbs elimination effect.Noise passes through the multiple reflections of noise elimination cavity, absorbs, energy dropoff, then is dispersed into air
In.
Above-described embodiment is only the description carried out to the preferred embodiment of the utility model, not to the model of the present invention
Enclose and be defined, on the premise of the spirit of the design of the utility model is not departed from, relevant technical staff in the field is to the utility model
Various modifications and improvement, should all expand determined by the utility model claims book in protection domain.
