Detailed Description
As shown in fig. 1 and 2, the utility model provides a compressor sound attenuation structure, including muffler 1, muffler 1 installs on the upper flange of compressor, is equipped with the through-hole on it, can be used to pass the cylinder of rotor or installation rotor, and wherein, the edge of through-hole is equipped with round baffle structure 11, can block the air current of assaulting the rotor, reduces the impact of the air current that flows from muffler 1 to the rotor, avoids the air current to assault the vortex noise that the rotor brought.
In a particular embodiment, the baffle structure 11 comprises: riser 111 and baffle 112, riser 111 sets up the round near the periphery of cylinder and is the arc, and baffle 112 perpendicular riser is around the cylinder round, keeps off in the top of the bloop of the noise elimination hole of muffler, reduces the impact of air current to the rotor.
The utility model discloses in, the top surface that 1 perpendicular rotor axial of muffler set up is equipped with a plurality of bloops 12 and gas vent 13, and the even interval in bloop 12 sets up, can eliminate the noise in one section frequency, improves the noise reduction effect, only is convenient for process more at the mode that the inlayer set up a plurality of bloops for among the prior art. The two air outlets 13 are arranged at the arc-shaped positions covered by the baffle plate structure, so that the air flow discharged from the air outlets 13 is over against the baffle plate of the baffle plate structure, and the air flow impacting the rotor and flowing out from the air outlets is blocked by the baffle plate structure.
As shown in fig. 3, the utility model discloses still include inlayer muffler 2, inlayer muffler 2 sets up between last flange and muffler 1, make and form two noise elimination chambeies between flange and the muffler 1, the top surface that the perpendicular rotor axial of inlayer muffler 2 set up is equipped with two noise elimination chambeies of a plurality of second noise elimination hole 21 intercommunication simultaneously, the even interval of second noise elimination hole 21 sets up, with the cooperation of the noise elimination hole 12 on the muffler 1, form double-deck amortization structure, can disappear the noise of one section or multistage frequency, noise range and noise cancelling effect have been increaseed. And the lateral wall that the parallel rotor axial of inlayer muffler 2 set up is equipped with exhaust hole 22, guarantees the exhaust of compressor normally, avoids influencing noise cancelling effect.
