Porous breather pipe is provided between mouthful.
Further, the air inlet and the gas outlet are respectively provided with flange plate, can design needed for different sizes are connected to
In pipeline.
Further, the expansion cavity is arranged in parallel three groups of expansion chambers, can effectively improve sound deadening capacity, expansion chambers described in three groups
Entrance both passes through first dividing plate, and expansion chambers outlet described in three groups is collected at one and through the second partition, and air-flow leads to
Noise can effectively be reduced by crossing the change in section.
Further, the sound-absorbing material is bonded in the inner walls, and the sound-absorbing material outer surface is set to ripple
Shape wave, the contact area of increase noise and the sound-absorbing material, the sound-absorbing material surface covers wire netting as pavement structure,
The sound-absorbing material can be protected.
Further, the lead to the hole site of the 3rd dividing plate, the 4th dividing plate and the 5th dividing plate is different, this
Sample can change the direction of airflow, effectively reduce noise.
Further, described porous breather pipe one end is fixedly connected on the 5th dividing plate, and the porous breather pipe is another
One end is fixedly connected on the gas outlet inwall.
Further, the through-hole diameter of the porous ventilation tube wall is set to from the remote gas outlet to the outlet
Mouthful direction is gradually reduced, different through-hole diameters can specific aim eliminate the noise of different frequency.
Relative to prior art, a kind of composite muffler described in the utility model has the advantage that：
(1) a kind of composite muffler described in the utility model effectively eliminates the noise of different frequency, practical.
(2) a kind of composite muffler described in the utility model is applied widely, and simple in construction, soundproof effect is preferable.
