Description
Technical field
The utility model relates to the blower fan silencing device of a kind of blower fan silencing device, particularly a kind of feed-processing equipment, belongs to blower fan noise reduction technical field.
Background technique
Baffler is to stop sound transmission and a kind of device of allowing air-flow to pass through, is the important measures of eliminating air power noise, and absorbing silencer refers to and in baffler, is provided with sound absorbing material, thereby sound absorbing material absorption of noise reduces noise.The blower fan of existing feed-processing equipment exists the shortcoming that noise is large, the blower fan configuring mostly is centrifugal fan, the noise of blower fan is 60-80 decibel, much several of the blower fan consumption of a set of mixed fodder process equipment, and mounting arrangements is all relatively concentrated, when working simultaneously, number Fans just more worsened working environment around, annual have a lot of operators to make impaired hearing because of the noise of blower fan, form noise occupation disease, existing absorbing silencer generally just has individual layer tube wall, in mono-layer tube, place acoustical cotton, when noise is through out-of-date, acoustical cotton can only absorb the noise of fraction, sound-absorbing effect is poor.
Summary of the invention
The problem existing for above-mentioned prior art, it is a kind of simple in structure that the utility model provides, and effectively reduces the blower fan silencing device of the feed-processing equipment of noise.
To achieve these goals, the technical solution adopted in the utility model is: a kind of blower fan silencing device of feed-processing equipment, comprise blower fan and power equipment, baffler and air outlet tube, baffler is arranged on the top of blower fan and power equipment, air outlet tube is arranged on the top of baffler, described baffler is comprised of inner tube, outer tube, acoustical cotton and air intake pipe, the tube wall place of described inner tube offers some vent holes, described acoustical cotton is filled in the cavity between outer tube and inner tube and in the cavity of inner tube, and described air intake pipe is arranged at the below of inner tube.
Further, described air intake pipe is taper air intake pipe.
The gross area of some vent holes that further, described inner pipe wall place offers accounts for the 25%-50% of the inner pipe wall gross area.
Further, the diameter of described vent hole is 2-4mm.
Further, the diameter of described vent hole is 3mm.
The beneficial effects of the utility model are: the blower fan silencing device of this feed-processing equipment is simple in structure, and be directly installed on the exhaust ports of blower fan, at the tube wall place of inner tube, offer some vent holes that match with noise audio frequency, noise can fully be contacted with acoustical cotton through this vent hole, can effectively reduce noise, improve sound-absorbing effect, reduce the generation of noise occupation disease.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, blower fan and power equipment, 2, baffler, 3, air outlet tube, 21, inner tube, 22, outer tube, 23, acoustical cotton, 24, air intake pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the blower fan silencing device of this feed-processing equipment, comprise blower fan and power equipment 1, baffler 2 and air outlet tube 3, baffler 2 is arranged on the top of blower fan and power equipment 1, air outlet tube 3 is arranged on the top of baffler 2, described baffler 2 is by inner tube 21, outer tube 22, acoustical cotton 23 and air intake pipe 24 form, the tube wall place of described inner tube 21 offers some vent holes, described acoustical cotton 23 is filled in the cavity between outer tube 22 and inner tube 21 and in the cavity of inner tube 21, described air intake pipe 24 is arranged at the below of inner tube 21, the blower fan silencing device of this feed-processing equipment is simple in structure, and be directly installed on the exhaust ports of blower fan, improve sound-absorbing effect, at the tube wall place of inner tube, offer some vent holes that match with noise audio frequency, more effectively reduced noise.
Described air intake pipe 24 is taper air intake pipe, and the air intake pipe of cone structure has further improved sound-absorbing effect; The gross area of some vent holes that described inner tube 21 tube wall places offer accounts for the 25%-50% of the inner tube 21 tube wall gross areas, the diameter of described vent hole is 2-4mm, the diameter of preferred described vent hole is 3mm, the structure of this design can fully contact through this vent hole noise with acoustical cotton, can effectively reduce noise, improve sound-absorbing effect, reduce the generation of noise occupation disease.
