Description
Technical field
The utility model relates to noise reducing apparatus technical field more particularly to a kind of compressor mufflers.
Background technique
Noise is one of the pollution sources of present society, and the noise that compressor generates be the important noise source of modern industry it
One, compressed air causes surrounding air to shake by exhaust outlet, to generate stronger noise.Silencer is abatement pneumatic noise
Device, it can allow air-flow to pass through, while can effectively stop surrounding air again and shaking and weaken sound and can propagate outward.
Currently, existing compressor air-discharging silencer mainly uses the resistance exhaust of pipeline section expansion and cross-sectional constriction to disappear
Sound device structure, using sound wave due to the variation of acoustic reactance at the abrupt change of cross-section, some sound wave is reflected back to sound source, and obstructed
The outlet of silencer is crossed, to achieve the purpose that noise elimination.This resistance exhaust silencer centering, low-frequency silencing noise effect
Preferably.And for high frequency noise, due to the number of the perforation pipeline section and perforated plate good to high frequency noise noise elimination effect of use
Measure less and internal without arranging the resistive sound-absorbing material good to high frequency noise sound absorption effect, it is to high frequency noise
Noise elimination effect is unsatisfactory.
Utility model content
In view of this, providing the compressor muffler that a kind of structure is simple, easy to use, noise elimination effect is good.
A kind of compressor muffler, including air inlet pipe, escape pipe, shell, first partition and second partition；Described first every
Plate and the second partition are by the inside interval of the shell；The air inlet pipe includes inlet pipe connection, intake noise reduction column, described
The interior of shell of the intake noise reduction column between drive end bearing bracket and the first partition, be located at the shell exterior described in into
The welding of gas connecting tube；The escape pipe includes outlet noise elimination column and outlet connecting tube, the outlet noise elimination column be located at rear end cap and
The interior of shell between the second partition is welded with the outlet connecting tube for being located at the shell exterior；Described first
Level sets 2 first through hole on partition, sets 2 the second through-holes on the second partition vertically；The intake noise reduction column with it is described
Outlet noise elimination column surface is equipped with sound attenuation hole of the same size, compressor noise pass sequentially through the inlet pipe connection, it is described into
Gas noise elimination column, the first through hole, second through-hole, the outlet noise elimination column and the outlet connecting tube arrange Xiang great Qi.
Further, the shell is cylindrical shape, and the outer wall of the shell is equipped with rock wool.
Further, the air inlet pipe, escape pipe and shell, which are fully welded, connects, and prevents gas leakage, and the air inlet pipe, outlet
Metal reinforcing plates are welded at pipe and cage connection.
Further, described outlet noise reduction column one end passes through the shell and the outlet connecting tube and welds, the other end with
The inner surface of outer cover welding.
Further, institute's first through hole and second through-hole are circle.
Compared with the prior art, the utility model has the following beneficial effects: compressor discharge noise through the air inlet pipe into
Enter in the shell between drive end bearing bracket and the first partition, realizes level-one expansion, eliminate the basic, normal, high frequency noise in part, together
When the transformation in the noise direction and vibration friction of the air inlet noise reduction column bloop, eliminate part high-frequency noise；Noise again from
The first through hole enters between the first partition, second partition, realizes second level expansion, eliminates the basic, normal, high frequency in part and makes an uproar
Sound；Noise passes through second through-hole again and enters between rear end cap and the second partition, realizes three-level expansion, eliminates part
Basic, normal, high frequency noise, then by the bloop on the outlet noise elimination column enter the outlet pipe connected pipe, by it is described go out
The discharge of gas connecting tube since the bloop by the outlet noise reduction column outer wall vibrates friction, and eliminates part high-frequency noise；Whole
During a, due to the rock wool sound absorption on the outer shell outer wall, it can eliminate in part, low, high-frequency noise.

Fig. 2 is the air feeder structure schematic diagram of the utility model embodiment.
Fig. 3 is the first partition structural schematic diagram of the utility model embodiment.
Fig. 4 is the second partition structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are please referred to, an embodiment of the present invention is shown, a kind of compressor muffler 10,
Including air inlet pipe 20, escape pipe 50, shell 60, first partition 30 and second partition 40；The first partition 30 and described second
Partition 40 is by the inside interval of the shell 60；The air inlet pipe 20 include inlet pipe connection 21, intake noise reduction column 22, it is described into
Gas noise elimination column 22 is inside the shell 60 between drive end bearing bracket and the first partition 30, and is located at outside the shell 60
The inlet pipe connection 21 welds；The escape pipe 50 includes outlet noise elimination column 51 and outlet connecting tube 52, and the outlet is eliminated the noise
Column 51 is inside the shell 60 between rear end cap and the second partition 40, be located at outside the shell 60 described in out
Gas connecting tube 52 is welded；Level sets 2 first through hole 32 in the first partition 30, sets 2 vertically on the second partition 40
Second through-hole 42；The intake noise reduction column 21 is equipped with sound attenuation hole of the same size with 51 surface of outlet noise elimination column, compresses
Machine noise passes sequentially through the inlet pipe connection 21, the intake noise reduction column 22, the first through hole 32, second through-hole
42, the outlet noise elimination column 51 and the outlet connecting tube 52 arrange Xiang great Qi.
Further, the shell is cylindrical shape, and the outer wall of the shell is equipped with rock wool.
