Continuous layer, described cotton-filtering layer one end and muffler valve seat are connected, and are also equipped with damping spring and spring stator on the screw rod,
Described damping spring one end is connected to spring stator, and the other end is connected to muffler valve seat, and the other end of the screw rod is also
Adjusting nut is installed.
Preferably, the muffler shell is bolted to connection with muffler valve seat.
Preferably, one is equipped between the cotton-filtering layer and muffler valve seat prevents cotton-filtering layer and muffler valve seat from connecting
Gap is generated between connecing and leads to the gasket of erasure effect difference.
Preferably, the enclosure interior is equipped with a filter mesh layer far from one end of muffler valve seat, and will by retaining ring
Filter mesh layer is fixedly mounted on inside muffler shell.
Preferably, the enclosure interior is provided with noise reduction filler, the filler between filter mesh layer and valve seat
For iron wire cloth.
Preferably, the filler is sound-proof material.
The beneficial effects of the utility model are as follows: the utility model provides to solve the problems, such as to mention in background technique
A kind of vacuum pump muffler, the shaft of the screw rod connection vacuum pump of muffler and receive the vibration that vacuum pump shaft transmits with
And noise, the damping spring can play the role of weakening vibration, and then prevent vacuum pump shaft and generate because of rotation
Bigger noise, and the noise come with vibration is filtered absorption of by cotton-filtering layer by cotton-filtering layer, therefore the technical program can be with
The noise issued when being significantly reduced vacuum pump work protects the health of worker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model muffler valve seat.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only in the utility model embodiment
For explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.In addition, the skill between each embodiment
Art scheme can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when technical solution
It will be understood that the combination of this technical solution is not present in conjunction with there is conflicting or cannot achieve when, also not in the utility model
It is required that protection scope within.
It as depicted in figs. 1 and 2, is a kind of vacuum pump muffler of the utility model, including muffler shell 10, it is described
Muffler valve seat 20 is fixedly installed with inside muffler shell 10, the muffler shell 10 passes through with muffler valve seat 20
Bolt 30 is fixedly connected, and a through-hole is opened up inside the muffler valve seat 20, is fixed with and disappears on the muffler valve seat 20
Mixer, the silencing means include a screw rod 40 for passing through 20 through-hole of muffler valve seat, are located at shell on the screw rod 40
Interior one end is from left to right separately installed with clamp nut 50, valve block 60 and cotton-filtering layer 70, described 70 one end of cotton-filtering layer and noise reduction
Device valve seat 20 is connected, and damping spring 80 and spring stator 90, the damping spring 80 1 are also equipped on the screw rod 40
End is connected to spring stator 90, and the other end is connected to muffler valve seat 20, and the other end of the screw rod 40 is also equipped with tune
Save nut 100.The screw rod 40 of the muffler of the utility model connects the shaft of vacuum pump and receives the shake that vacuum pump shaft transmits
Dynamic and noise, the damping spring 80 can play the role of weakening vibration, rotate adjusting nut according to the size of vibration
100 change the length of damping springs 80 to adapt to the seismaesthesia of varying strength, and then prevent vacuum pump shaft and produce because of rotation
