Abstract
The utility model discloses a middle cavity structure of a silencing device in a filter silencer, comprising an outer shell plate, an outer shell sound absorption layer, an outer shell perforation plate and middle silencing sheets, wherein the outer shell sound absorption layer is disposed between the outer shell plat and the outer shell perforation plate; a plurality of middle silencing sheets is disposed at the middle of the outer shell perforation plate; the plurality of middle silencing sheets is uniformly arranged along the normal direction of an air flowing passage; and the distance between the adjacent middle silencing sheets is equal to the distance X between the middle silencing sheets and the outer shell perforation plate. The middle cavity structure of a silencing device in a filter silencer disclosed by the utility model is compact and reasonable in structure; and because the width of the air flowing passage is not greater than the thickness of the sound absorption layer, the silencing effect is remarkably improved, and the noise is ensured to satisfy the standard of environmental protection.
Description
Technical field
The utility model relates to cavity configuration in the filter and sound damper silencer, and specifically a kind of improvement structure of filter and sound damper silencer belongs to the mechanical structure technical field.
Background technique
In existing technology, the filter and sound dampers that adopt before the high-speed centrifugal fan intake grill more, cavity configuration is made up of several anechoic sheets in the silencing apparatus silencer, and each anechoic sheet is evenly arranged along the air flow channel normal direction.Because the sound-absorbing material layer thickness and the distances when compared between the anechoic sheet of anechoic sheet are less relatively, make the noise elimination effect can not reach related request.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby cavity configuration in a kind of filter and sound damper silencer is provided, and its noise elimination is effective, can compliance with environmental protection requirements.
The technological scheme that provides according to the utility model; Cavity configuration comprises Shell Plate, shell absorbent treatment, shell perforated plate, middle anechoic sheet in the filter and sound damper silencer; Be provided with the shell absorbent treatment between said Shell Plate and the shell perforated plate; Be provided with several middle anechoic sheets in the middle of the said shell perforated plate, said several middle anechoic sheets arrange evenly that along the air flow channel normal direction spacing of adjacent middle anechoic sheet and middle anechoic sheet equate with the spacing X of shell perforated plate.
As further improvement of the present invention, said middle anechoic sheet is made up of intermediate perforated plate, middle absorbent treatment, absorbent treatment in the middle of intermediate perforated plate coats.
As further improvement of the present invention, said spacing X is the air flow channel width, and spacing X is not more than 20 mm.
As further improvement of the present invention, the thickness Y of said shell absorbent treatment and middle absorbent treatment equates that said thickness Y is not less than 20 mm.
As further improvement of the present invention, said shell absorbent treatment adopts super glass wool or mineral wool sound-absorbing material to process.
As further improvement of the present invention, said middle absorbent treatment adopts super glass wool or mineral wool sound-absorbing material to process.
Compared with present technology the utility model has the following advantages:
The utility model compact structure, reasonable; Because the air flow channel width is no more than absorbent treatment thickness, and the noise elimination effect is significantly improved, and guarantees that noise meets environmental protection standard.
Description of drawings
Fig. 1 is the filter and sound damper structural representation.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1: this filter and sound damper comprises parts such as air filter 1, silencer 2; Silencer 2 is arranged in the air filter 1.Cavity configuration comprises Shell Plate 3, shell absorbent treatment 4, shell perforated plate 5, middle anechoic sheet 6 etc. in the said silencer 2.
Be provided with shell absorbent treatment 4 between said Shell Plate 3 and the shell perforated plate 5, said shell absorbent treatment 4
Adopt super glass wool or mineral wool sound-absorbing material to process.Be provided with several middle anechoic sheets 6 in the middle of the said shell perforated plate 5, said several middle anechoic sheets 6 arrange evenly that along the air flow channel normal direction spacing of adjacent middle anechoic sheet 6 and middle anechoic sheet 6 equate with the spacing X of shell perforated plate 5.Said spacing X is the air flow channel width, and spacing X is not more than 20 mm.Anechoic sheet 6 is made up of intermediate perforated plate 6-1, middle absorbent treatment 6-2 in the middle of said, absorbent treatment 6-2 in the middle of intermediate perforated plate 6-1 coats.The thickness Y of said shell absorbent treatment 4 and middle absorbent treatment 6-2 equates that said thickness Y is not less than 20 mm.Absorbent treatment 6-2 adopts super glass wool or mineral wool sound-absorbing material to process in the middle of said.
When the utility model used, atmosphere got into filter and sound damper from inlet A, filtered through air filter 1, passed through shell noise elimination wall and the noise elimination of middle anechoic sheet 6 in the silencer 2 again, got into the blower fan suction chamber in exhaust outlet B at last.Experiment proof: air flow channel width X is no more than sound absorption thickness Y, and Y is when being not less than 20mm, and its noise elimination effect is significantly improved, and can reach environmental protection standard fully.
