Description
Technical field
The present invention relates to muffler technical field, specially a kind of Rotary Muffler for Engine.
Background technology
Traditional muffler has：Resistive muffler, resistant noise-reducing device, resistive muffler are to utilize sound-absorbing material or sound absorption knot
The sound absorption of structure reaches noise elimination effect.And resistant noise-reducing device is to utilize acoustic impedance mismatch, makes the sound wave of certain frequencies in sound
The interface of change in the instantaneous impedance occurs reflection, interferes and reach noise elimination purpose.Because there is resistance when being vented in air flue in resistive muffler
Power has severely impacted volumetric efficiency, and consumes quite a few power, while increasing noxious emission and fuel consumption；
Resistant noise-reducing device noise elimination effect is influenced very big by working frequency, and noise elimination effect is poor.
Invention content
In view of the above problems, the present invention provides a kind of Rotary Muffler for Engine, by by resistive muffler and anti-
Property muffler be combined together, devise a kind of dynamic muffler, improve erasure effect, improve volumetric efficiency, reduced
Evil gas discharge, can effectively solve the problems in background technology.
To achieve the above object, the present invention provides the following technical solutions：A kind of Rotary Muffler for Engine, including noise reduction
Device shell, the muffler shell front end are equipped with nose air intake, and the muffler shell is socketed on the exhaust pipe of engine, and
It is separated by graphite annulus and the exhaust pipe of engine, the muffler shell rear end is equipped with rear air inlet, and rear air inlet passes through
Ball bearing is connected with rear support axis, and rear support axis is divided into three parts in car body rack in the muffler shell body, most before
End is expansion chambers, and middle section is resonant chamber, is backmost metal anechoic chamber, is separated with sound-absorbing partition between various pieces.
As a kind of preferred technical solution of the present invention, the muffler shell is in evolvent type, and muffler shell two
Side is provided with exhaust outlet.
As a kind of preferred technical solution of the present invention, what the nose air intake and rear air inlet were connect with muffler shell
Place is lined with super glass wool.
As a kind of preferred technical solution of the present invention, multiple layer metal sound insulation disk is installed in the metal anechoic chamber, gold
Belong on sound insulation disk is porous metals eyed structure.
Compared with prior art, the beneficial effects of the invention are as follows：The Rotary Muffler for Engine, by setting muffler
It is set to rotary vertical installation, air admission hole and gas vent is increased, improves volumetric efficiency, and by resistant noise-reducing element expansion chambers
It is combined together with resistive silencer element metal sound insulation disk with resonant chamber, forms novel impedance muffler, and when exhaust gas is from two
When the opposite gas vent in direction is discharged, exhaust energy is converted into muffler and extraneous frictional heat, so that exhaust energy is reduced, sound
Power declines so that noise greatly reduces.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment：
It please refers to Fig.1 and Fig. 2, the present invention provides a kind of technical solution：A kind of Rotary Muffler for Engine, including noise reduction
Device shell 1,1 front end of the muffler shell are equipped with nose air intake 2, and the muffler shell 1 is socketed in the exhaust pipe of engine 3
On, and separated by graphite annulus 4 and the exhaust pipe of engine 3,1 rear end of the muffler shell is equipped with rear air inlet 5, and laggard
Gas port 5 is connected with rear support axis 7 by ball bearing 6, rear support axis 7 in car body rack 8；Divide in the muffler shell 1
For three parts, front end is expansion chambers 9, and middle section is resonant chamber 10, is backmost metal anechoic chamber 11, various pieces it
Between separated with sound-absorbing partition 12, the muffler shell 1 is in evolvent type, and shell both sides are provided with exhaust outlet 13, the advance
It is all fixed with super glass wool 14 at gas port 2 and rear air inlet 5, multiple layer metal sound insulation disk is installed in the metal anechoic chamber 11
15, metal sound insulation disk 15 is equipped with many screenings.
The automobile exhaust gas that the exhaust pipe of engine 3 is discharged enters muffler shell by nose air intake 2 and rear air inlet 5
Body 1, due between the exhaust pipe of engine 3 and muffler air inlet, being that high-temperature component is in contact, therefore is carried out using graphite annulus 4
It is heat-insulated, it prevents high temperature from damaging muffler, and lubricating action can be played, reduces friction when rotation；The ball bearing 6 and rear branch
Muffler is fixed in car body rack 8 by support axis 7, and the muffler in rotation process is prevented to be detached from original place；Into muffler shell 1
Interior exhaust gas, the gas expansion first in expansion chambers 9 weaken noise subsequently into resonance occurs in resonant chamber 10, enter back into gold
Belong in anechoic chamber 11 by 15 noise reduction of the disk of metal sound insulation layer by layer；The super glass wool 14 can absorb a part of noise, and energy
Pellet is enough absorbed, certain tail gas clean-up can be played the role of；Last exhaust gas is arranged by the tail portion of muffler shell 1
Stomata 13 be discharged, when the exhaust gas of high temperature, high pressure is discharged on the contrary from exhaust gas from both direction, silencer body by recoil force effect,
Start to rotate, exhaust energy is converted into muffler and extraneous frictional heat, and exhaust energy is made to reduce, and acoustical power declines so that
Noise greatly reduces.
The Rotary Muffler for Engine increases air admission hole and row by the way that muffler is arranged to rotary vertical installation
Stomata improves volumetric efficiency, and by resistant noise-reducing element expansion chambers and resonant chamber with resistive silencer element metal sound insulation disk
It is combined together, forms novel impedance muffler, improve erasure effect, while reducing energy consumption, reduce pollution.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
