Silencer is a kind of device for reducing Fluid Air kinetic noise.Fans silencer main function is to reduce wind turbine to send
Wind turbine and primary air fan and seal fan inlet air flow noise.It is ground having carried out a large amount of analysis to wind turbine and matched silencer
Study carefully, the smaller silencer of fluid resistance, eliminated the noise with meeting Wind Volume pressure fan, the best requirement of flow resistance.Suitable for centrifugal wind
Machine and axial fan.
Now with the severe of environment, especially when equipment works, introduced contaminants object is more, and fans silencer easily sucks
Impurity thing, and then the structure inside silencer is caused to be damaged, at summer, poplar wadding is disorderly, into fans silencer, nothing
Image of Buddha other impurities particle easy cleaning is accumulated, equipment is caused not operate effectively for a long time, hinders acoustic(al)absorbent that can not eliminate the noise；
It is frequently necessary to be cleared up and be safeguarded, increase maintenance cost.
Utility model content
The utility model is easily accessible impurity thing, especially poplar wadding to solve existing fans silencer, damages internal junction
Structure, proposes a kind of dust-proof silencer of fan inlet at the problems such as equipment is caused not operate effectively.
To achieve these goals, the technical solution adopted in the utility model is as follows：
The dust-proof silencer of fan inlet, including suppressor case, it is characterised in that：The left side of the housing is equipped with air inlet
Mouthful, the air inlet is equipped with Air Filter, catch is additionally provided with outside air inlet, the air inlet outer ring is equipped with flange collar, described dust-proof
It nets outer ring and is equipped with groove, the flange collar is correspondingly connected with groove；The right side of the housing is equipped with air outlet；It is equipped in the housing
Hinder acoustic form.
Further, the resistance acoustic form is divided into level-one noise elimination structure and two level noise elimination structure, the level-one noise elimination structure
Partition is equipped between two level noise elimination structure.
Further, described state is equipped with resistance tablet in level-one noise elimination structure and two level noise elimination structure, is set in the resistance tablet
There are web plate, superfine glass fiber cotton and glass hole cloth.
Further, the housing is equipped with perforated plate.
Further, the housing right end connects air outlet by reducer pipe.
Further, the air outlet is equipped with flange.
Further, the housing is externally provided with end ear.
Further, the housing is welded using carbon steel steel plate group.
The utility model has the advantages that：
Protection network is equipped in the front end of silencer inlet scoop, prevents sundries from entering, especially stops poplar wadding, ensures internal unit
It works well, prolongs the service life, reduce repair and clearing times, reduce maintenance cost.
Air Filter is movably connected on silencer, can conveniently be removed and be cleaned, then be installed again, in this way may be used
To ensure silencer continuous firing, without shutting down.
The utility model effectively prevent the sundries such as polybag leaf to enter silencer, blocks silencer orifice plate, influences noise reduction
Effect is effectively guaranteed the function that effect is deteriorated after silencer is used for a long time.
The utility model is simple in structure, effective dust, and manufacture is of low cost, and maintenance and cleaning equipment number is reduced.

Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, the dust-proof silencer of fan inlet, including suppressor case 1, it is characterised in that：A left side for the housing 1
Side is equipped with air inlet 12, and the air inlet 12 is equipped with Air Filter 9, is additionally provided with catch 6 outside air inlet 12, outside the air inlet 12
Circle is equipped with flange collar 11, and 9 outer ring of Air Filter is equipped with groove 10, and the flange collar 11 is correspondingly connected with groove 10；The housing 1
Right side is equipped with air outlet 4；Resistance acoustic form is equipped in the housing 1.
The resistance acoustic form is divided into level-one noise elimination structure and two level noise elimination structure, and the level-one noise elimination structure and two level are eliminated the noise
Partition 7 is equipped between structure.Described state is equipped with resistance tablet 8 in level-one noise elimination structure and two level noise elimination structure, in the resistance tablet 8
Equipped with web plate, superfine glass fiber cotton and glass hole cloth.The housing 1 is equipped with perforated plate.1 right end of housing passes through reducer pipe 2
