Specific embodiment
The drawings and specific embodiments are combined to make the application technical solution claimed herein further details of
Explanation.
Generated noise, the application disclose a kind of rotor-type compressor sound absorber when in order to eliminate compressor rotation
Generated noise carries out absorption elimination when to compressor rotation, shown in structure combination Fig. 1-Fig. 5 of the sound absorber, packet
The shell 1 for being set in outside rotor-type compressor cylinder has been included, sound-absorbing material is laid on the inner sidewall of the shell 1 as suction
Sound layer 2；When compressor rotation, sound-absorbing material rotates issued sound to compressor as absorbent treatment 2 and absorbs, thus
Realize noise elimination.
The shell 1 can using latten roll form or plastic injection made of any shape, such as without up and down
The hexahedron or cylinder of bottom plate；Shell 1 is provided herein and includes left end edge 11 and right end edge 12, left end edge 11 and the right side
End margin 12 is fixedly connected with the cylinder housing of composition, left end edge 11 and right end edge, and there are holes 13, in conjunction with such as Fig. 1 and figure
Shown in 2；It can be convenient and shell 1 be set in outside the cylinder of compressor to eliminate compressor rotation and to be produced by the hole at both ends
Raw noise.
In order to enable shell 1 to be stably mounted at, compressor barrel is external, and the cooperation of utilization " L " type connector 4 is fixed herein
Part 15 (nut+screw) shell 1 is installed on outside the cylinder 6 of rotor-type compressor.
Left end in order to further improve the sound absorption effect of sound absorber provided by the utility model, on shell 1
The junction at edge 11 and right end edge 12 is laid with yielding rubber 5.It is outstanding there are being conducive at left end edge 11 or right end edge 12
The aperture 14 of extension is convenient for phosphatization.
In addition, the sound absorber further includes cap 3, it is equally laid with absorbent treatment 2 on the inner sidewall of the cap 3, by shell 1
Cap 3 is covered on shell 1 after being set in outside the cylinder of compressor, interference fit is formed between the two and is fixedly mounted, will press
Contracting machine ontology is placed in shell 1, as shown in Figure 6, Figure 7.Absorbent treatment 2 is laid on shell 1 and cap 3, sound absorption effect is more
It is good.
The thickness of shell 1, cap 3 documented by the application according to actual use situation depending on, use herein with a thickness of
0.5mm~1.5mm；The thickness of shell 1, absorbent treatment 2 on 3 inner sidewall of cap is laid in depending on actual use situation,
This lay with a thickness of 5mm~15mm.
Absorbent treatment 2 documented by the application can be constituted using existing any sound-absorbing material, use trimerization herein
Melamine resin foam sound-absorbing material constitutes three dimensional network structure.The utility model be by melamine resin foam sound-absorbing material and
Latten is constituted, and passes through a variety of to absorb noise, sound by two kinds of composite constructions of sound-absorbing material and sound insulating material
After different media, intensity of acoustic wave obviously weakens, to achieve the purpose that eliminate noise.
Here, selection 0.8mm hot rolled steel plate makes sound absorption structure described in the utility model, by 5mm melamine resin
Foam sound-absorbing material is pasted onto backing material inner wall, is then installed on the cylinder 6 of compressor, and lid, which will close cap 3, to be compressed
The upper casing 7 of machine is placed in the cavity being made of shell 1 and cap 3, but does not coat the lower outer cover 8 and liquid storage cylinder 9 of compressor,
As shown in Figure 6, Figure 7.The noise test of 6.3K, 12.5K and total value are carried out after having assembled, test result is shown in Table 1.
Table 1 6.3K, 12.5K and total value noise testing result
| State | 6.3K | 12.5K | Noise total value |
| Without sound absorption structure | 52.5dB | 40.3dB | 56.3dB |
| There is sound absorption mechanism | 43.7dB | 35.1dB | 51.9dB |
Noise elimination effect is obvious as can be known from Table 1, and has carried out acoustic absorptivity test to it, test result as shown in Fig. 8,
Sound absorber provided by the utility model reaches 0.3 or more, 12.5K to the acoustic absorptivity of 6.3K and 12.5K as shown in Figure 8
