Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of air compressor, particularly a kind of sound proofing enclosure of air compressor.
Background technique
Air compressor is the basic product of the modernization of industry, and that often says electrically and in automation just has entirely pneumatic implication; And air compressor is just to provide source of the gas power, it is the main body in the dynamo-electric bleed air source device of nucleus equipment of pneumatic system, it is the device mechanical energy of former dynamic (normally motor) being converted to gas pressure energy, is compressed-air actuated pressure generator.
It is by motor direct driving compressor machine, makes bent axle produce rotary motion, and drivening rod makes piston produce to-and-fro motion, causes volume of cylinder to change.Due to the change of inner pressure of air cylinder; air is made to enter cylinder through air-strainer (silencing apparatus) by suction valve; in compression stroke; due to reducing of volume of cylinder; pressurized air is through the effect of outlet valve; through outlet pipe, one-way valve (safety check) enters gas holder, is controlled and autostop by pressure switch when exhaust pressure reaches rated pressure.
Disclosed in Chinese patent literature, (application number: 201310222296.7), comprises cylinder to a kind of air compressor, and cylinder is provided with suction port, air outlet and mount inlet; Getter assembly, getter assembly is located on described cylinder, getter assembly involving vibrations film, and diaphragm closes described mount inlet; One-way air inlet part, one-way air inlet part closes suction port; With unidirectional part of giving vent to anger, unidirectional part of giving vent to anger coordinates with air outlet.Be provided with dividing plate in cylinder and the interior space of cylinder is become plenum chamber and gas storage chamber by dividing plate, suction port is communicated with plenum chamber respectively with mount inlet, and air outlet is communicated with described gas storage chamber, and dividing plate is provided with pore, and unidirectional part sealed porosity of giving vent to anger.But comparatively official post noise is larger for the shell soundproof effect of this air compressor.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the sound proofing enclosure of the good air compressor of a kind of soundproof effect.
The purpose of this utility model realizes by following technical proposal: the sound proofing enclosure of air compressor, comprise the housing for placing compressor, described housing is square and adopts insulation board to make, it is characterized in that, described insulation board comprises madial wall and outer side wall, described insulation board runs through and has some bloops, described bloop along madial wall outward sidewall direction reduce, the outer side wall uniform fold of described insulation board has one deck sound deadening sheet, described sound deadening sheet is provided with some through holes, and described through hole is corresponding one by one with described bloop.
Because compressor is placed in housing, during work, when the noise that air compressor produces passes the bloop of insulation board, noise is along the hole wall transmission of bloop, consume the energy of noise, reduce noise decibel, simultaneously again by the Noise Reduction of the through hole of sound deadening sheet, again absorb the energy of noise, make this sound proofing enclosure have good soundproof effect.
In the sound proofing enclosure of above-mentioned air compressor, the diameter of described through hole is less than the diameter of described bloop and the through hole of the described of correspondence and described bloop are coaxially arranged.Bloop is arranged in coaxial with through hole, has the effect absorbing noise energy preferably.
In the sound proofing enclosure of above-mentioned air compressor, described bloop is the step hole on 2 to 4 rank.Bloop is step hole, makes it have the larger hole wall of area to absorb the energy of noise.
In the sound proofing enclosure of above-mentioned air compressor, the rank exponent number of adjacent described step hole is all not identical.The exponent number of adjacent step hole is all not identical, enables insulation board absorb the noise of different frequency.
In the sound proofing enclosure of above-mentioned air compressor, the both sides of described housing are provided with air-inlet sound eliminator, and the air-inlet sound eliminator described in two is symmetrical set.By being symmetrical arranged air-inlet sound eliminator, can, by the Noise insulati on of hull outside wall, extraneous noise be avoided to mix with the noise in housing.
Compared with prior art, the sound proofing enclosure of this air compressor has the following advantages:
1, because compressor is placed in housing, when the noise that air compressor produces passes the bloop of insulation board, noise, along the hole wall transmission of bloop, consumes the energy of noise, reduces noise decibel;
2, by the Noise Reduction of the through hole of sound deadening sheet, again absorb the energy of noise, make this sound proofing enclosure have good soundproof effect;
3, bloop is step hole, makes it have the larger hole wall of area to absorb the energy of noise;
4, by being symmetrical arranged air-inlet sound eliminator, can, by the Noise insulati on of hull outside wall, extraneous noise be avoided to mix with the noise in housing.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the sound proofing enclosure of this air compressor.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
In figure, 1, housing; 2, insulation board; 2a, bloop; 3, sound deadening sheet; 3a, through hole; 4, air-inlet sound eliminator.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As illustrated in fig. 1 and 2, the sound proofing enclosure of air compressor, comprise the housing 1 for placing compressor, housing 1 is square and adopts insulation board 2 to make, and insulation board 2 comprises madial wall and outer side wall, insulation board 2 runs through and has some bloop 2a, bloop 2a along madial wall outward sidewall direction reduce, the outer side wall uniform fold of insulation board 2 has one deck sound deadening sheet 3, and sound deadening sheet 3 is provided with some through hole 3a, and through hole 3a is corresponding one by one with bloop 2a.The diameter of through hole 3a is less than the diameter of bloop 2a and the through hole 3a of correspondence and bloop 2a is coaxially arranged, and has the effect absorbing noise energy preferably.
Bloop 2a is the step hole on 2 to 4 rank, makes it have the larger hole wall of area to absorb the energy of noise; The rank exponent number of adjacent step hole is all not identical, makes insulation board 2 can absorb the noise of different frequency.
