Detailed description of the invention:
The application is not limited by following embodiment, can determine specifically according to the technical scheme of the application and practical situation
Embodiment.
As shown in Figure 1, 2, the silencing means of boiler combustion head includes blower fan 1 and sound-muffling box；Blower fan 1 is positioned at sound-muffling box
In, air outlet 14 one end of sound-muffling box correspondence blower fan 1 is that end-cover-free is arranged, the end cap of the air inlet 15 of sound-muffling box correspondence blower fan 1
It is provided with the air intake passage 3 of coupling；Air intake passage 3 outer end connects has inside to arrange bending for disappearing of buffering and communicate with the external world
Sound air channel.
During installation, air outlet 14 correspondence of blower fan 1 is arranged on boiler 2, by one end of sound-muffling box end-cover-free by blower fan 1
Covering in inside sound-muffling box, one end of sound-muffling box end-cover-free is connected with boiler 2 laminating, forms a confined space, and air intake passage 3
Just corresponding at the air inlet 15 of blower fan 1；Again inside is arranged on air intake passage 3 with the noise elimination wind conduit that bending buffers.
The noise that blower fan 1 produces is absorbed by sound-muffling box and is hedged off from the outer world and comes, and plays the effect reducing noise；Enter at a high speed blower fan 1
The air of air inlet 15 need to first pass through the noise elimination wind conduit with bending, then entered by air intake passage 3, play effectively buffering,
Greatly reduce the fricative huge sound；Use the noise that the application rear fan 1 produces by original 100 decibels after measured
Left and right is reduced to less than 70 decibels；Not only decrease sound pollution, it is to avoid operating personnel upsets, distraction,
Affect work efficiency, have an accident；The audition of operating personnel, physiology, mental health are served relative protective effect.
As it is shown in figure 1, sound-muffling box includes the shell layer 5 of outside and internal stratum reticulare 6 of breaing up, shell layer 5 with break up stratum reticulare 6
Between be provided with the first sound absorbing layer 7.The huge noise that so blower fan 1 produces can be broken up by the dispersion of each working lining: first passes around and breaks up
Stratum reticulare 6 is broken up, and is then passed through the first sound absorbing layer 7 and successively absorbs, and is finally completely cut off by the shell layer 5 of outer layer and comes, really plays
Reduce the effect of noise.During processing, the first sound absorbing layer 7 can use acoustical cotton, utilize acoustic resistance to reduce noise, sound wave
Micropore numerous in acoustical cotton moves, buffers and absorbs, makes acoustical cotton no longer have sound wave near that plane of shell layer 5
Reflect away, reduce or eliminate the purpose of sound wave.
As it is shown in figure 1, the inner face of the first sound absorbing layer 7 is crest shape.The effect absorbing noise of the first sound absorbing layer 7 can be improved
Really.
As shown in Figure 1, 2, noise elimination wind conduit inwall is provided with the second sound absorbing layer 4；The port that noise elimination wind conduit communicates with the external world is provided with
Filtering meshes 16.Filtering meshes 16 can effectively be broken up and decompose impurity in the air-flow, and filtered airflow rapidly entering noise elimination wind conduit, pure
Net airflow enters the air inlet 15 of blower fan 1 again through the noise reduction of the second sound absorbing layer 4, dust suction process by air intake passage 3；Such one
It is considerably reduced the dust that blower fan 1 sucks, while noise reduction, decreases blower fan 1 maintenance times, increase service life.
As shown in Figure 1, 2, noise elimination wind conduit includes the air channel, the end 17 that is connected and two crosswind roads 18；Air channel, the end 17 is detachable
Be arranged on bottom sound-muffling box, two crosswind roads 18 are detachably arranged on sound-muffling box two side, air channel, the end 17 with described enter
Wind passage 3 communicates.Air channel, the end 17 and crosswind road 18 form the gas channel of U-shaped, and air-flow lowers into the end through two crosswind roads 18
Air channel 17, then level flow at air intake passage 3, ascends into the air inlet 15 of blower fan 1 the most again；So it is avoided that air-flow is straight
Connect and enter at a high speed blower fan 1, produce huge vibrations, friction, thus reach noise reduction purpose.
As shown in Figure 1, 2, the silencing means of boiler combustion head also includes multiple supporting leg 8, on each supporting leg 8 longitudinally
It is provided with hole, multiple location 9；The sidewall bottom of sound-muffling box is provided with multiple slideway 10 slided up and down for supporting leg 8, and slideway 10 sets
There is alignment pin 11；By coordinating of location hole 9 and alignment pin 11, each supporting leg 8 is fixed in corresponding slideway 10.So may be used
According to actually used situation, on regulation supporting leg 8, the hole 9, location of diverse location coordinates with the alignment pin 11 on slideway 10, thus
Change the height of the application, increase the scope of application.
As shown in Figure 1, 2, the bottom of supporting leg 8 is provided with universal wheel 12, and universal wheel 12 is provided with brake gear 13.Universal
Mobile sound-muffling box is easy in the setting of wheel 12, facilitates one end of sound-muffling box end-cover-free to be connected with boiler 2 laminating, is placed in close by blower fan 1
Close in space；The design of brake gear 13 can be after sound-muffling box position determines, locked universal wheel 12；Sound-muffling box is avoided to make an uproar because absorbing
Sound produces to shake and is subjected to displacement and reduces the effect of absorption noise.
Above technical characteristic constitutes the most preferred embodiment of the application, and it has stronger adaptability and most preferably implements effect
Really, inessential technical characteristic can be increased and decreased according to actual needs, meet the needs of different situations.
