Abstract
The invention discloses an air outlet structure of a filter silencer. The air outlet structure comprises an outer shell panel, a bottom perforation plate and a sound absorption material; the sound absorption material is arranged between the outer shell panel and the bottom perforation plate; a plane in the bottom perforation plate and the inner cavity of a cylindrical air outlet are vertically arranged, and are provided with a tangential transition arc; and the arc radius R of the tangential transition arc is not less than the distance X from the plane in the bottom perforation plate to the outer plane of the outer shell panel. The structure provided by the invention is compact and resonable; and the air channel is of a tapered type, the resistance is less, and defects of great resistance and easiness in noise increasing caused by the abrupt contraction of the air channel of the prior art are overcome.
Description
Technical field
The present invention relates to the filter and sound damper air outlet structure, 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 to be arranged vertically with silencing apparatus inner chamber bottom surface, does not have filtering section, makes the air flow flip-flop through herein, and resistance increases, and is easy to generate new noise.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of improvement structure of filter and sound damper exhaust outlet is provided, its air flow resistance is little, noise is low.
According to technological scheme provided by the invention, 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 described shell flat board and the bottom perforated plate, described bottom perforated plate inner plane and cylindrical exhaust outlet inner chamber are arranged vertically, and bottom perforated plate inner plane and cylindrical exhaust outlet inner chamber are provided with tangent transition arc.
As a further improvement on the present invention, the radius of arc of described tangent transition arc is not less than bottom perforated plate inner plane to the dull and stereotyped outerplanar distance of shell.
As a further improvement on the present invention, described X distance is not less than 20mm.
As a further improvement on the present invention, described sound-absorbing material adopts different materials under different situations, as super glass wool, mineral wool etc.
Compared with the prior art the present invention has the following advantages:
Compact structure of the present invention, 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 reaches easy increase noise greatly suddenly.
Description of drawings
Fig. 1 is the filter and sound damper structural representation.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: this filter and sound damper comprises parts such as air filter 1, silencer 2; The present invention includes component such as shell flat board 3, bottom perforated plate 4, sound-absorbing material 5.
Be provided with sound-absorbing material 5 between described shell dull and stereotyped 3 and the bottom perforated plate 4, described sound-absorbing material 5(adopts different materials under different situations, as super glass wool, mineral wool etc.).Bottom perforated plate inner plane 4-1 and cylindrical exhaust outlet inner chamber 4-2 are arranged vertically, 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.Described X distance is not less than 20mm.Atmosphere enters filter and sound damper from inlet A, filters through air filter 1, enters the suction chamber of high-speed centrifugal fan again in exhaust outlet B through silencer 2 noise elimination backs.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.
