Detailed Description

As shown in fig. 1, the present embodiment provides a silencing structure for a compressor, which includes a silencing barrel and a silencing cover 1 disposed on the silencing barrel, a silencing cavity is formed between the silencing cover and the silencing barrel, and the silencing structure can be placed between a first-order exhaust port and a second-order exhaust port in the exhaust of a cylinder block.

Wherein, amortization lid 1 sets up at the top of amortization section of thick bamboo, is equipped with exhaust inlet 6 and exhaust outlet 7 on the outer wall of amortization section of thick bamboo, exhaust inlet 6 and exhaust outlet 7 extend to the inside of muffler respectively and form the cantilever pipe, evenly be equipped with a plurality of pipeline micropore 8 on the cantilever pipe, after gas gets into the inside back of making an uproar that falls of amortization section of thick bamboo from exhaust inlet 6, rethread exhaust outlet 7 discharges, wherein pipeline micropore 8 on the cantilever pipeline can make exhaust runner pressure even, reduces the exhaust pulsation to preliminarily making an uproar falls.

The wall in amortization chamber comprises shell 2 and inner shell 3, wherein be equipped with the clearance between shell 2 and the inner shell 3, be equipped with sound absorbing material 5 in this clearance, be equipped with sound insulating material 10 on the internal face of amortization lid simultaneously, noise abatement after the air admission amortization chamber expansion that gets into from the exhaust inlet like this, wherein the noise of surrounding noise passes through sound absorbing micropore on inner shell and the shell and is absorbed by inside sound absorbing material 5, the noise at top prevents the propagation route of noise through sound insulating material 10 that the amortization was covered, can fall the comprehensive making an uproar, compare in, current amortization package is big in structure, and need the space requirement, the steam generator is simple in structure, occupation space is little, can the direct mount exhaust intracavity portion.

The utility model discloses well sound attenuation section of thick bamboo wall is not only limited to the one deck between inner shell 3 and the shell 2 in this embodiment and is used for placing the attraction material, also can be more than the one deck, and sound absorbing effect can be better like this, but structure and holistic weight can increase, so need confirm how many layers that its sound absorbing material set up according to the position of this amortization structure installation.

Further, the sound micropore 4 is inhaled to the surface that is equipped with a plurality of on this embodiment inner shell 3 and shell 2, and these sound micropore 4 of inhaling mainly absorb the noise of the ring week in the amortization intracavity, so inhale sound micropore 4 and carry out annular distribution on inner shell and shell, also set up the multilayer simultaneously, can guarantee like this that the noise of ring week can evenly enter into the sound absorbing material 5 between inner shell and the shell through these sound micropore 4 of inhaling.

The sound-absorbing micro-holes 4 in the inner casing 3 and the outer casing 5 may be arranged in an overlapping manner or in a staggered manner.

In this embodiment, the exhaust inlet 6 and the exhaust outlet 7 on the wall of the muffler cylinder extend through the wall of the muffler cylinder toward the inside of the muffler cylinder to form a cantilever pipe, and the cantilever pipe is used for connecting the exhaust ports of the exhaust chambers in the cylinder block.

Preferably, the cantilever pipe in this embodiment is integrally disposed below the sound-absorbing micro-holes 4 on the sidewall of the silencing pot.

The exhaust inlet 6 is connected with the first-order exhaust port in the cylinder seat in an aligned mode, and the exhaust outlet 7 is connected with the second-order exhaust port in the cylinder seat in an aligned mode, so that gas generated by the cylinder seat enters the interior of the silencing cavity through the cantilever pipe and directly enters the second-order exhaust port along the cantilever pipe after noise is eliminated.

In this embodiment, evenly be equipped with a plurality of pipeline micropore 8 on the cantilever pipe, these pipeline micropores 8 evenly set up on the wall face of cantilever pipe, when getting into the amortization intracavity from cylinder block department gas vent like this, on the one hand, can be even to the air current pressure of entering through pipeline micropore 8 on the cantilever hole, on the other hand, can wholly reduce carminative pulsation.

In order to fix the silencing cavity in the embodiment, a screw hole 12 is formed in the center of the top of the silencing cover in the embodiment, and the structure can be fixed on the cylinder seat through a bolt.

Meanwhile, the positioning block 11 is arranged on the outer wall surface of the silencing cover, is arranged along the outer edge of the silencing cover, can be integrated with the silencing cover and can also be detachably connected with the silencing cover, and is mainly used for determining the mounting positions of an exhaust inlet and an exhaust outlet in the structure.

Considering that the mounting position of the structure is determined according to the positions of the air inlet and the air outlet on the silencing cover 1, the adjustment is hard, so the positions of the air inlet and the air outlet can be determined by determining the mounting position of the positioning block on the silencing cover 1, and the positioning block 11 can be supported on the base to fix the silencing cover.

In this embodiment, a sound-deadening layer 10 is disposed on an inner wall surface of the sound-deadening cap 1, the sound-deadening layer 10 may be made of a sound-deadening material such as silica gel, and the sound-deadening layer 10 is distributed over the entire inner wall surface of the sound-deadening cap, so that a propagation path of noise at the top of the sound-deadening chamber can be blocked by the sound-deadening cap 1.

In addition, the utility model discloses another embodiment still discloses a compressor, including the aforesaid in the compressor a amortization structure, the exhaust intracavity in the cylinder block can be placed to the amortization structure, specifically sets up between first-order gas vent and the second order gas vent on the cylinder block, and the amortization is covered and is equipped with the screw hole, can fix it on the cylinder block through the bolt like this, replaces a amortization lid or the amortization package of current simple through this amortization structure and falls the function of making an uproar, has so both reduced the exhaust pulsation, has reduced the noise again.
