Abstract
The utility model provides an air intake box which is mounted at an air inlet of an air compressor. The air intake box comprises a box body, an air inlet arranged at the top of the box body, and an air outlet arranged on the side face of the lower part of the box body and connected with the air inlet of the air compressor. During the operation of the air compressor, the air firstly enters the inside of the air intake box through the air inlet, passes through a sound insulation sponge that is packed inside the box body and enters the air inlet of the air compressor through the air outlet, and at that time the noise generated during the operation of the air compressor is transferred outwards through the box body; in the direction opposite to the direction of the air entering the box body, as the blades of the shutter are tilted towards the upward outer side of the box body, the noise enters the air outlet with the shutter of the box body firstly where the noise is stopped and then partially absorbed, subsequently the noise enters the inside of the box body under the guide action of the blades of the shutter and moves to the lower part of the box body where the noise is blocked and returned by the sponge and the wall of the box body, and then the noise moves upwards and goes out of a filter screen cover plate, so that the noise is repeatedly blocked and returned until being eliminated. Therefore, the air intake box can reduce the noise generated during the operation of the air compressor.
Description
Technical field
The utility model belongs to the air-pressure equipment field, relates in particular to the denoising structure that is used for air compressor.
Background technique
The drive manner of air compressor mainly is that air compression is stored to gas tank, and when air compressor carries out work, the operation of a machine meeting produces very big noise, environment there is certain pollution, the mode that solves the air compressor noise is got up the used for air compressor body seal often at present, leaves wind inlet in a side, though such structure can reduce some noises, but noise still spreads out of by wind inlet, and noise reduction is not clearly.
The model utility content
The purpose of this utility model is to provide a kind of inlet box, is intended to solve the excessive problem of air compressor running noise.
The utility model is achieved in that a kind of inlet box, places air compressor wind inlet place, comprises a casing, and described casing top is provided with intake grill, and the lower box side is provided with the exhaust outlet that is connected with the air compressor wind inlet.
Preferably, described intake grill place is provided with cover plate.
Particularly, described cover plate is penetrating filter screen.
Preferably, described exhaust outlet place is provided with venetian blind.
Particularly, described shutter blade outwards tilts the top.
Further, sound insulation by filling material in the described casing.
Particularly, described soundproof material adopts sponge.
Use inlet box provided by the utility model, after air compressor wind inlet place assembling behind the described inlet box, during the air compressor running, air enters in the utility model casing by intake grill earlier, the sound insulation sponge that passes the interior filling of casing is transported to the exhaust outlet place and enters the air compressor wind inlet, and this moment, the noise that the air compressor running is produced will outwards be propagated by casing, to enter the casing direction opposite with air, at first enter the exhaust outlet that casing has venetian blind, because the louvre blade of venetian blind top outside casing tilts, noise upwards spreads out of the filter screen cover plate after being subjected to digesting and assimilating after certain stopping a part and entering the obstruction bounce-back that runs into sponge and box body wall behind the casing after lower box is propagated by the louvre blade guiding, the noise of this moment consumes through repeatedly rebounding, thereby the noise of the running generation of air compressor is minimized.
Description of drawings
Fig. 1 is the stereogram that the utility model embodiment provides;
Fig. 2 is that the inlet box that the utility model embodiment provides combines side schematic view with air compressor.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in seeing figures.1.and.2, the utility model provides a kind of embodiment of air compressor inlet box, and it places air compressor wind inlet 6 places, comprises a casing 1, described casing 1 top is provided with intake grill 3, and casing 1 lower side is provided with the exhaust outlet 2 that is connected with air compressor wind inlet 6.Further, described intake grill 3 places also can be provided with penetrating filter net type cover plate 4, exhaust outlet 2 places are provided with venetian blind 5, and this venetian blind 5 is provided with the louvre blade that a plurality of outside tops that are arranged in parallel tilt, and fills the soundproof material (omission illustrates) that adopts the sponge sound insulation in the casing 1.In concrete the enforcement, use the inlet box that the utility model embodiment is provided, after described inlet box is assembled at air compressor wind inlet 6 places, during air compressor 7 runnings, air enters in the casing 1 by filter screen cover plate 4, the sound insulation sponge that passes casing 1 interior filling is transported to exhaust outlet 2 places and enters machine wind inlet 6, and this moment, the noise that running produced of air compressor 7 is outwards propagated by casing 1, to enter casing 1 direction opposite with air, at first enter the exhaust outlet 2 that casing 1 has venetian blind 5, because the louvre blade of venetian blind 5 top outside casing 1 tilts, noise is subjected to digesting and assimilating after certain stopping a part and enters by the louvre blade guiding and upwards spreads out of filter screen cover plate 4 casing 1 back runs into the obstruction bounce-back of sponge and casing 1 wall after propagate casing 1 bottom after, the noise of this moment is through the approach exhaustion that repeatedly rebounds, thereby the noise that the running that makes air compressor 7 produces is reduced greatly, reaches the purpose of noise reduction.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
