Description
Technical field
The utility model relates to blower technical fields, and in particular to a kind of novel fan silencer.
Background technique
Blower is to improve gas pressure by the mechanical energy of input and supply gas side by side the machinery of body, it is a kind of driven stream
Body is mechanical.Blower is to the habit abbreviation of gas compression and gas conveying machinery, and usually said blower includes ventilation blower, air blast
Machine and wind-driven generator etc..Blower be widely used in factory, mine, tunnel, cooling tower, vehicle, ship and building ventilation,
Dust discharge and cooling.
Blower during operation, can generate very big noise, this noise, which usually becomes, influences workers ' health and interference
The misfortune source of environment, the especially blower adjacent to living area, the air power noise that air inlet and air outlet are radiated, even more
The principal element of environment is polluted, the noise that blower generates has become one of the main object of noise control pollution.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of novel fan silencer is provided.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: novel fan silencer, including eliminate the noise
Device outer cylinder, silencer inner cylinder, acoustical cotton and the mounting assembly for connecting with blower, the silencer inner cylinder are sleeved on silencer
In outer cylinder, the acoustical cotton is arranged on the inner wall of silencer outer cylinder, and innovative point is: the silencer outer cylinder and silencer
The front end of inner cylinder is fixedly connected by the way that first annular baffle is arranged, and the rear end of the two is fixedly connected by the second ring baffle,
Opened up on the first annular baffle sound-absorbing opening, and sound-absorbing opening be fixedly installed leading note ring, the silencer inner cylinder with
Sound absorption cavity is formed between silencer outer cylinder, the barrel of the silencer inner cylinder is wavy shaped configuration, is fixed in the mounting assembly
Setting leading note, which is bored, to be emitted.
Further, the mounting assembly includes the guide shell of taper and the flange that connect with blower.
Further, the taper of the leading note cone cap is 30-45 °, and is fixed at and is led by setting screw bolt and nut
On the inner wall of flow cartridge.
Further, acoustical cotton is similarly fixedly installed on the inner wall of the silencer inner cylinder, and acoustical cotton is and noise elimination
The wavy shaped configuration that the inner wall of device inner cylinder is consistent.
Further, the length of the silencer outer cylinder and silencer inner cylinder is 1.5 times of silencer outer barrel diameter.
After adopting the above structure, the utility model has the beneficial effect that
The utility model simple structure and reasonable design can play sound-absorbing effect, excellent noise reduction effect；When sound is from blower
When the outflow of inside, a part of sound is passed to inside sound absorption cavity by leading note ring and is isolated, in sound absorption cavity along guide shell inner wall
Noise can be made to rebound to the greatest extent, noise reduction, finally dissolved by acoustical cotton, another part sound bores cap by leading note and rebounds to disappearing
On the inner wall of sound device inner cylinder, and by the multiple rebound of inner wall, it is finally reached the effect of noise reduction.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols:
1 silencer outer cylinder, 2 silencer inner cylinders, 3 acoustical cottons, 4 mounting assemblies, 41 guide shells, 42 flanges, 5 first annular gears
Plate, 51 sound-absorbings opening, 6 second ring baffles, 7 leading note rings, 8 sound absorption cavities, 9 leading notes cone emit, 10 bolts.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, a kind of novel fan silencer, including silencer outer cylinder 1, silencer inner cylinder 2, acoustical cotton 3 and be used for
The mounting assembly 4 connecting with blower, silencer inner cylinder 2 are sleeved in silencer outer cylinder 1, and acoustical cotton 3 is arranged in silencer outer cylinder 1
Inner wall on, silencer outer cylinder 1 and the front end of silencer inner cylinder 2 be fixedly connected by the way that first annular baffle 5 is arranged, and the two
Rear end is fixedly connected by the second ring baffle 6, sound-absorbing opening 51 is opened up on first annular baffle 5, and at sound-absorbing opening 51
Leading note ring 7 is fixedly installed, forms sound absorption cavity 8 between silencer inner cylinder 2 and silencer outer cylinder 1, the barrel of silencer inner cylinder 2 is wave
Shape wave structure, fixed setting leading note cone emits 9 in mounting assembly 4.
In the present embodiment, the guide shell 41 of mounting assembly 4 including taper and the flange 42 being connect with blower.41 energy of guide shell
Enough by sound dispersion, convenient for entering in sound absorption cavity 8 from sound-absorbing opening 51.
