Abstract
The invention relates to a fan sound eliminator which comprises a housing, sound elimination pieces, a sound absorbing material, installing flanges and an interface flange. Two ends of the housing are respectively and fixedly connected with the interface flanges, the sound elimination pieces and the sound absorbing material are located in the housing, the sound elimination pieces are arranged at intervals, two ends of each sound elimination piece are respectively and fixedly connected with the installing flanges, the sound absorbing material is filled in each sound elimination piece, and the installing flanges are fixed to the interface flanges. The fan sound eliminator has the advantages of being simple in structure and convenient to install.
Description
Technical field
The present invention relates to a kind of fans silencer.
Background technique
Blower fan is a kind of general machinery equipment, and its using scope is very wide, and the production of the every profession and trades such as electric power, mine, machinery, metallurgy, chemical industry all be unable to do without blower fan.The noise of the on-stream generation of blower fan usually becomes the misfortune source affecting workers ' health and interference environment.The particularly blower fan in contiguous living area, the air power noise of its intake grill and the radiation of exhaust outlet institute, the principal element of befouling environment especially, forms public hazards, is Industry Branch in recent years, one of main object that noise control pollutes.
Although be applied on blower fan at more existing silencing apparatuss on the market, the complex structure of these silencing apparatuss, assemble cumbersome.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to, provide the fans silencer that a kind of structure is simple, easy for installation.
The technological scheme solved the problems of the technologies described above is as follows:
Fans silencer, comprise housing, anechoic sheet, sound-absorbing material, mounting flange, flange, the two ends of housing are fixedly connected with flange respectively, anechoic sheet and sound-absorbing material are all positioned at housing, anechoic sheet carries out cloth postpone with the form at interval, the two ends of anechoic sheet are fixedly connected with mounting flange respectively, and described sound-absorbing material is filled in every sheet anechoic sheet, and mounting flange is fixed on flange.
Have employed such scheme, when air or gas flow through the anechoic sheet passage be longitudinally arranged in metal shell, enter by the anechoic sheet of both sides inner during air sound wave, the sound-absorbing material be filled in anechoic sheet absorbs needs decay, to reach the object reducing noise.Can be used for invention the air power noise reducing the generation of various blower fan, there is the features such as sound deadening capacity is large, anechoic frequency bandwidth, drag losses are little, structure is simple, easy for installation.The industries such as power station, petrochemical industry, mine, metallurgy, building can be widely used in.
Also comprise stiffening rib, this stiffening rib is arranged in the outer wall of housing.Added the intensity of housing by stiffening rib, the bulk strength of product is obtained and strengthens, avoid falling apart in transport or installation process.
Accompanying drawing explanation
Fig. 1 is the structural representation of fans silencer of the present invention;
In accompanying drawing, 1 is housing, and 2 is anechoic sheet, and 3 is sound-absorbing material, and 4 is mounting flange, and 5 is flange, and 6 is stiffening rib.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
With reference to Fig. 1, fans silencer of the present invention, comprises housing 1, anechoic sheet 2, sound-absorbing material 3, mounting flange 4, flange 5.The two ends of housing 1 are fixedly connected with flange 5 respectively, and the two ends of housing 1 are welded and fixed with flange respectively.Also comprise stiffening rib 6, this stiffening rib is arranged in the outer wall of housing.Anechoic sheet 2 and sound-absorbing material 3 are all positioned at housing, and anechoic sheet 2 is arranged along the longitudinal direction of housing.Anechoic sheet 2 carries out cloth postpone with the form at interval, and the two ends of anechoic sheet 2 are fixedly connected with mounting flange 4 respectively, and described sound-absorbing material 3 is filled in every sheet anechoic sheet 2.Mounting flange 4 is fixed on flange 5.
Claims (2)
1. a fans silencer, it is characterized in that: comprise housing, anechoic sheet, sound-absorbing material, mounting flange, flange, the two ends of housing are fixedly connected with flange respectively, anechoic sheet and sound-absorbing material are all positioned at housing, anechoic sheet carries out cloth postpone with the form at interval, the two ends of anechoic sheet are fixedly connected with mounting flange respectively, and described sound-absorbing material is filled in every sheet anechoic sheet, and mounting flange is fixed on flange.
2. fans silencer according to claim 1, is characterized in that: also comprise stiffening rib, this stiffening rib is arranged in the outer wall of housing.
