Abstract
The utility model discloses an air outlet structure of filter silencer, which comprises a housing flat plate, a bottom perforated plate and a noise absorbing material; the noise absorbing material is arranged between the housing flat plate and the bottom perforated plate; the inner plane of the bottom perforated plate is vertical to the inner cavity of the cylindrical air outlet; and the inner plane of the bottom perforated plate and the inner cavity of the cylindrical air outlet are provided with tangent transition arcs. The arc radius R of the tangent transition arc is not smaller than the distance X from the inner plane of the bottom perforated plate to the outer plane of the housing flat plate. The air outlet structure is compact and reasonable in structure; the air flow channel is gradually reduced and has smaller resistance force, so that the defect on large resistance force and easy noise increment resulted from sudden reduction of the air flow channel in the prior art is overcome.
Description
Technical field
The utility model relates to the filter and sound damper air outlet structure, and specifically a kind of follow-on mechanical structure in filter and sound damper outlet port 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, the exhaust outlet of silencing apparatus is connected with the intake grill of blower fan.Mostly the exhaust outlet of this type of filter and sound damper is the cylindrical cavity body structure, and the inwall of cylindrical cavity becomes vertical layout with silencing apparatus inner chamber bottom surface, does not have filtering section, makes the air flow flip-flop through here, and resistance increases, and is easy to generate new noise.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby a kind of improvement structure of filter and sound damper exhaust outlet is provided, and its air flow resistance is little, noise is low.
The technological scheme that provides according to the utility model; The filter and sound damper air outlet structure comprises shell flat board, bottom perforated plate, sound-absorbing material composition; Be provided with sound-absorbing material between said shell flat board and the bottom perforated plate; Said bottom perforated plate inner plane is provided with tangent transition arc with vertical layout of cylindrical exhaust outlet inner chamber, bottom perforated plate inner plane and cylindrical exhaust outlet inner chamber.
As further improvement of the present invention, the radius of arc of said tangent transition arc is not less than the dull and stereotyped outerplanar distance of bottom perforated plate inner plane to shell.
As further improvement of the present invention, said X distance is not less than 20mm.
As further improvement of the present invention, said sound-absorbing material adopts different materials under different situations, like super glass wool, mineral wool etc.
Compared with present technology the utility model has the following advantages:
The utility model compact structure, reasonable; Air flow channel is gradual shrinkage, and resistance is less, has overcome the prior art air flow channel and has dwindled the shortcoming that the resistance that causes increases noise greatly and easily suddenly.
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; The utility model comprises component such as shell flat board 3, bottom perforated plate 4, sound-absorbing material 5.
Be provided with sound-absorbing material 5 between said shell dull and stereotyped 3 and the bottom perforated plate 4, said sound-absorbing material 5 (under different situations, adopting different materials) like super glass wool, mineral wool etc.Bottom perforated plate inner plane 4-1 and vertical layout of cylindrical exhaust outlet inner chamber 4-2; Bottom perforated plate inner plane 4-1 and cylindrical exhaust outlet inner chamber 4-2 are provided with tangent transition arc 4-3, and radius of arc R is not less than the distance X of bottom perforated plate inner plane 4-1 to the dull and stereotyped outerplanar 3-1 of shell.Said X distance is not less than 20mm.Atmosphere gets into filter and sound damper from inlet A, and process air filter 1 filters, and eliminates the noise the back in the suction chamber of exhaust outlet B entering high-speed centrifugal fan through silencer 2 again.Because the air flow channel at exhaust outlet place is gradual shrinkage, resistance is less, can not produce the high resistant noise that causes because of the runner sudden change.
