Description
Technical field
The present invention relates to a kind of air compressor, more specifically, it relates to a kind of noise-reducing structure of air compressor.
Background technology
Air compressor is a kind of equipment to compressed gas, directly drives compressor by motor, produces bent axle
Rotary motion, drivening rod make piston produce reciprocating motion, cause volume of cylinder to change.In compression travel, because cylinder holds
Long-pending diminution, compressed air pass through the effect of air bleeding valve, enter air accumulator through blast pipe, when pressure at expulsion reaches rated pressure
Controlled and autostop by pressure switch during 0.7MPa.Air compressor is by the machine of former dynamic (being typically motor or diesel engine)
Tool can be converted into the device of gas pressure energy, be the pressure generator of compressed air.
But when compressed gas is constantly delivered in air accumulator by compressor, air accumulator compressed air is in air-flow arteries and veins
In the presence of dynamic, excited vibrational is produced, so as to the noise of accompanied by intense, while air accumulator vibration radiation noise is excited, influences work
Make environment, thus it is to be modified.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of noise-reducing structure of air compressor,
It reduces the effect of noise with that can reduce air vibration in air accumulator.
To achieve the above object, the invention provides following technical scheme：
A kind of noise-reducing structure of air compressor, including air accumulator, length of the roof along air accumulator in the air accumulator
Direction is provided with several pegs, and shown peg underhung has sound-absorptive object, is provided with what is be connected with peg on shown sound-absorptive object
Hook, shown sound-absorptive object surface is densely covered with bloop.
Preferably, the sound-absorptive object includes two pieces of interlaced acoustical panels, and the bloop is located on acoustical panel, described
Hook is at the intersection of two pieces of acoustical panels, the intersection of two pieces of acoustical panels and the diameter parallel of air accumulator.
Preferably, the pore diameter range of the bloop is 0.1mm-0.5mm.
Preferably, the gas storage top tank structure is provided with muffle coating.
Preferably, the gas storage tank wall is coated with silencing cotton.
Preferably, the gas storage tank wall is provided with heat dissipating layer between silencing cotton and gas storage tank wall.
Preferably, multiple heat emission holes are provided with the silencing cotton.
Compared with prior art, the invention has the advantages that：
Multiple sound-absorptive objects are hung by the roof in air accumulator, hinder tank standing internal wave to be formed, so as to reach sqouynd absorption lowering noise
Purpose, sound-absorptive object includes two fast acoustical panels, and two pieces of acoustical panels are staggered, are densely covered with bloop in noise reduction version, can offset
The standing wave of tank body radially, different according to different air accumulator internal volumes, caused standing wave amplitude is different, therefore selects bloop
For pore diameter range in 0.1mm between 0.5mm, gas storage top tank structure is provided with muffle coating, can absorb and be delivered in gas storage top tank structure
On sound wave, reduce the vibration of air accumulator itself, gas storage tank wall is coated with silencing cotton, can reduce acoustic wave segment and be passed into air
Pass, because compressed air produces heat, therefore heat dissipating layer is set on the outer wall of air accumulator, prevents that air accumulator temperature is too high, pass through
Heat emission hole is set on silencing cotton, being capable of improving radiating effect.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
A kind of noise-reducing structure of air compressor, with reference to Fig. 1 and 2, it includes air accumulator 1, and the roof in air accumulator 1 is along storing up
The length direction of gas tank 1 is provided with several pegs 11, and the underhung of peg 11 has sound-absorptive object, and sound-absorptive object includes two pieces and mutually handed over
Wrong acoustical panel 2, is provided with the hook 21 be connected with peg 11 at the intersection of two pieces of acoustical panels 2, the intersection of two pieces of acoustical panels 2 and
The diameter parallel of air accumulator 1, for eliminating the standing wave of radial direction in air accumulator 1；The surface of acoustical panel 2 is densely covered with bloop 22, noise reduction
The pore diameter range in hole 22 is 0.1mm-0.5mm, can use same apertures or different pore size, for eliminating single sound wave or difference
The sound wave of frequency.
The inwall of air accumulator 1 is provided with muffle coating 12, the sound-absorbing material such as the usable resins of muffle coating 12 or rubber, for inhaling
The sound wave for being transferred to the inwall of air accumulator 1 is received, reduces the vibration of air accumulator 1, so as to lift noise reduction, the outer wall of air accumulator 1 cladding
There is silencing cotton 3, silencing cotton 3 can be made up of materials such as polyester fiber or polyethylene, transmitted for reducing sound wave into air, entered one
Step reduces noise；The outer wall of air accumulator 1, which is located between silencing cotton 3 and the outer wall of air accumulator 1, is provided with heat dissipating layer 4, and heat dissipating layer 4 can use
Thermal grease or graphite radiating film etc., multiple heat emission holes 31 are provided with silencing cotton 3, for improving radiating effect, prevent gas storage
