Detailed description of the invention
As shown in Figures 1 to 4, this utility model provides a kind of Simple muffler, including silencing cavity 10
And the polylith silencing baffles 30 being arranged in silencing cavity 10.
Wherein, one end of silencing cavity 10 is provided with the inlet suction port for being connected with the air vent of industrial equipment
21, the other end is filled with sound-absorbing material 22.In the present embodiment, silencing cavity 10 include hollow cylinder 11,
Fix the protecgulum 12 being connected to fix with hollow cylinder 11 other end to be connected with hollow cylinder 11 one end
Bonnet 13；In the specific implementation, protecgulum 12, bonnet 13 are equal when be connected fixing with hollow cylinder 11
Can use threaded.Above-mentioned inlet suction port 21 is arranged on protecgulum 12, and silencing baffles 30 is positioned at
In hollow cylinder 11, sound-absorbing material 22 contacts with bonnet 13.In the present embodiment, inlet suction port 21
It is coaxially disposed with hollow cylinder 11, silencing baffles 30, bonnet 13.Bonnet 13 is hemispherical, on it
Being provided with some steam vents 14, sound-absorbing material 22 is filled with the inside at bonnet 13.At this utility model
Another embodiment in, bonnet 13 can be directly a flat board, and it equally can arrange steam vent,
Now sound-absorbing material 22 can be filled in the end of flat board and hollow cylinder 11.
In the present embodiment, silencing cavity 10 uses metal material to make, i.e. hollow cylinder 11, protecgulum 12,
Bonnet 13 all uses metal material.Sound-absorbing material 22 be metal wool, glass fiber material, cotton yarn or
At least one in cotton.Usually, if deafener is in high-temperature work environment, sound-absorbing material 22 is suitable
Select metal wool, if deafener is in normal operating conditions, can be selected for cotton yarn, cotton etc..
Also include bolt 40, be arranged on the sidewall of silencing cavity 10, and bolt 40 and silencing baffles 30
Upper surface or lower surface at least one side be close to, in order to limit its position in silencing cavity 10.
Specifically, hollow cylinder 11 having multiple screwed hole, bolt 40 stretches into from the outer wall of hollow cylinder 11
Screwed hole also protrudes from the inwall of hollow cylinder 11.If deafener takes the mode uprightly placed, then spiral shell
Bolt 40 is positioned at the lower section of silencing baffles 30, after now being tightened completely by bolt 40, it is possible to will
Silencing baffles 30 lies in bolt 40 top and holds silencing baffles 30；If deafener needs horizontal positioned,
Then the both sides of silencing baffles 30 are required for arranging bolt 40, so that silencing baffles 30 is positioned completely.
Preferably, silencing baffles 30 is close to by bolt 40, and the bolt 40 of the every side of silencing baffles 30 can be 4,
Silencing baffles 30 external diameter 0.5mm-2mm less than the internal diameter of hollow cylinder 11.It should be noted that when disappearing
When sound baffle plate 30 has enough wall thickness, bolt can also directly be driven into the sidewall of silencing baffles 30
Realizing location, the location mode of certain silencing baffles 30 is not limited only to bolt location, silencing baffles 30
Also can be connected by the mode such as screw thread, jump ring with between hollow cylinder 11.
In the present embodiment, silencing baffles 30 is two pieces, silencing cavity 10 is divided into 3 volumes close
Anechoic chamber.More specifically, silencing baffles 30 is arranged on 1/3 and 2/3 position of hollow cylinder 11,
Certainly, the number of silencing baffles 30 is not limited by the present invention.
As it is shown on figure 3, silencing baffles 30 includes noise reduction district 32 and the gas corresponding with inlet suction port 21
Stream direct projection district 31, noise reduction district 32 is provided with several noise reduction holes 33, in the present embodiment, every piece of noise reduction
Circling gas flow direct projection district, noise reduction hole 33 31 on baffle plate 30 arranges formation multilamellar circumference, and circling gas flow is straight
Penetrate district 31 and be positioned at the center of silencing baffles 30.Noise reduction hole 33 on adjacent silencing baffles 30 is mutual
Stagger.
The Simple muffler simple in construction that this utility model provides, volume is little, and raw material sources is extensive,
It is easy to make and install, is particularly suited for industrial equipment and discharges industrial noise produced by high-speed gas.
High velocity air enters in the silencing cavity that this utility model provides by inlet suction port, by through noise reduction
Twice expansion of anechoic chamber in the obstruction of baffle plate and cylinder, effectively reduces exhaust noise, and noise reduction keeps off
