Pressure vessel is divided into three classes by the effect in production.And to the pressure vessel of each classification in design, manufacturing process, and examine
Project, content and mode are made that different regulations.Pressure vessel needs a large amount of exhausts outward in 0.4Mpa, in the mistake of exhaust
It will produce harsh noise in journey, need to use muffler progress noise reduction.Silencer is to prevent sound transmission and allow air-flow logical
A kind of device crossed is the important measures for eliminating air power noise.Silencer is mounted in air powered equipment (such as air blast
Machine, air compressor machine) gas channel on or inlet and exhaust system in reduction noise device.But the noise reduction of existing pressure vessel
Device, simple in structure, the effect of sound-deadening and noise-reducing is not fine.Therefore, it is proposed that a kind of muffler of pressure vessel.
Utility model content
The main purpose of the utility model is to provide a kind of mufflers of pressure vessel, pass through at the top of air inlet short tube
Second venthole of one venthole and outlet short tube bottom, the first venthole and the second venthole jet noise by when can be with
So that noise is substantially reduced, by the acoustical cotton in the bloop and bloop in silencing cavity, noise can be absorbed, be passed through
Enlarged tube at the top of gas outlet can be realized to gas flow rate into row buffering and carry out multistage sound-deadening and noise-reducing to noise, improve
The using effect of muffler can play dust-proof effect, effectively avoid dust by the dust-proof mesh enclosure at the top of enlarged tube
Into muffler, the using effect of muffler is influenced, can effectively solve the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of muffler of pressure vessel, including fixed disc, air inlet short tube, silencing cavity, outlet short tube and enlarged tube, institute
It states and is installed with air inlet short tube in the middle part of fixed disc, air inlet short tube bottom is through fixed disc, the air inlet short tube
Top is fixedly connected with silencing cavity and is applied in silencing cavity at the top of air inlet short tube, and multigroup uniform row is offered in the silencing cavity
The bloop of row is mounted on acoustical cotton in the bloop, is fixedly connected with outlet short tube at the top of the silencing cavity, it is described go out
Shortness of breath tube top portion is fixedly connected with gas outlet, is fixedly connected with enlarged tube at the top of the gas outlet, fixed at the top of the enlarged tube
Dust-proof mesh enclosure is installed.
Further, mounting hole is offered on the fixed disc, the mounting hole shares three groups.
Further, multigroup the first evenly distributed venthole is offered at the top of the air inlet short tube.
Further, outlet short tube bottom is applied in silencing cavity and outlet short tube bottom offers multigroup uniform row
Second ventilation hole of row.
Further, it is closed that the air inlet short tube is applied in one end in silencing cavity with outlet short tube.
Compared with prior art, the utility model has the advantages that：
1. the muffler of the pressure vessel of the utility model passes through the first venthole and outlet short tube at the top of air inlet short tube
Second venthole of bottom, the first venthole and the second venthole jet noise by when noise can be made to be substantially reduced, lead to
The acoustical cotton in bloop and bloop in silencing cavity is crossed, noise can be absorbed, the expansion at the top of gas outlet is passed through
Pipe can be realized to gas flow rate into row buffering and carry out multistage sound-deadening and noise-reducing to noise, improve the use effect of muffler
Fruit.
2. the muffler of the pressure vessel of the utility model can be played dust-proof by the dust-proof mesh enclosure at the top of enlarged tube
Effect, effectively avoid dust and enter muffler, influence the using effect of muffler.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of muffler of pressure vessel, including fixed disc 2, air inlet short tube 1, silencing cavity 5, outlet
Short tube 7 and enlarged tube 9,2 middle part of the fixed disc are installed with air inlet short tube 1, and 1 bottom of air inlet short tube is through admittedly
Fixed disk 2,1 top of the air inlet short tube is fixedly connected with silencing cavity 5 and 1 top of air inlet short tube is applied in silencing cavity 5, described
Multigroup evenly distributed bloop 11 is offered in silencing cavity 5, and acoustical cotton 12, the noise reduction are mounted in the bloop 11
5 top of chamber is fixedly connected with outlet short tube 7, and 7 top of the outlet short tube is fixedly connected with gas outlet 8,8 top of the gas outlet
It is fixedly connected with enlarged tube 9,9 top of the enlarged tube is installed with dust-proof mesh enclosure 10.
