Abstract
The invention discloses a kind of ship muffler, including smoke-intake pipe, hush pipe and smoke exhaust pipe, one end connection smoke-intake pipe of the hush pipe, the other end connects smoke exhaust pipe, the hush pipe includes muffler inner tube and muffler outer tube, densely covered bloop is offered on the tube wall of the muffler inner tube, the muffler inner tube outer surface is coated with noise reduction layer, and the noise reduction layer is enclosed between muffler inner tube and muffler outer tube by the muffler outer tube.The advantage of the invention is that：The ship is relatively low with muffler cost of manufacture, more hommization is designed, by using the isolation of hush pipe, reduce heat, the diffusion of noise belowdecks, reach good sound-insulating and heat-insulating effect, noise and heat in cabin are effectively reduced, so as to alleviate the harm to human body.
Description
Technical field
The present invention relates to muffler technical field, more particularly to a kind of ship muffler.
Background technology
In the ship of big navigation in the sea, engine is typically all diesel engine, and is all the ventilation condition in cabin
Difference, at present, the smoke exhaust pipe of engine is one layer of simple tube wall, and sound insulation, effect of heat insulation are all bad, diesel engine acc power
Greatly, noise, the heat sent is also big, and heat that engine is sent, noise etc. can be all diffused into cabin, and ship navigates for a long time
During row, cause that the noise in cabin is very big, and temperature is very high, crewman is lived in cabin, will influence crewman's body over time
Health.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of ship that can be improved performance muffler and effectively discharge fume with disappearing
Sound device.
In order to solve the above technical problems, the technical scheme is that：A kind of ship muffler, its innovative point are：
Including smoke-intake pipe, hush pipe and smoke exhaust pipe, one end connection smoke-intake pipe of the hush pipe, the other end connects smoke exhaust pipe, described to disappear
Sound tube includes muffler inner tube and muffler outer tube, and densely covered bloop is offered on the tube wall of the muffler inner tube, described
Muffler inner tube outer surface is coated with noise reduction layer, the muffler outer tube by the noise reduction layer be enclosed in muffler inner tube and
Between muffler outer tube.
Further, the bloop is in the netted circular hole to gather on inner pipe wall.
Further, the noise reduction layer is made up of the tightly packed sound-absorbing material between muffler inner and outer pipe.
Further, the muffler inner tube and muffler outer tube are stainless steel tube.
The advantage of the invention is that：The ship is relatively low with muffler cost of manufacture, more hommization is designed, by using disappearing
The isolation of sound tube, heat, the diffusion of noise belowdecks are reduced, reaches good sound-insulating and heat-insulating effect, effectively reduced in cabin
Noise and heat, so as to alleviate the harm to human body.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation of ship muffler of the present invention.
Fig. 2 is a kind of sectional view of the hush pipe of ship muffler of the present invention.
Fig. 3 is the structural representation of densely covered bloop in a kind of muffler inner tube of ship muffler of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
As shown in Figure 1 to Figure 3, a kind of ship muffler, including smoke-intake pipe 1, hush pipe 2 and smoke exhaust pipe 3, hush pipe 2
One end connection smoke-intake pipe 1, other end connection smoke exhaust pipe 3, hush pipe 2 includes muffler inner tube 4 and muffler outer tube 5, noise reduction
Densely covered bloop 6 is offered on the tube wall of device inner tube 4, bloop 6 is in the netted circle to gather on the tube wall of muffler inner tube 4
Hole, the outer surface of muffler inner tube 4 are coated with noise reduction layer 7, and noise reduction layer 7 is the tightly packed sound-absorbing between muffler inner and outer pipe
Material is made, and noise reduction layer 7 is enclosed between muffler inner tube 4 and muffler outer tube 5 by muffler outer tube 5, in muffler
Pipe 4 and muffler outer tube 5 are stainless steel tube.
In use, the device to be connected to the exhaust apparatus of engine, the present apparatus is reduced by using the isolation of hush pipe
The diffusion of heat, noise belowdecks, reach good sound-insulating and heat-insulating effect, effectively reduce noise and heat in cabin, from
And alleviate the harm to human body.
The noise reduction principle of bloop 6 is：When air-flow is by densely covered bloop 6, the frequency spectrum of noise will shift to high frequency
Or hyperfrequency, the audible sound composition in frequency spectrum is substantially reduced, so as to reduce the interference to the human body sense of hearing and injury.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
For art personnel it should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is explanation
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
