Mutually be staggered arrangement on the left and right directions and above-below direction of muffler, is arranged in array respectively in left wall and right wall,
Each left (or right) bloop is between neighbouring two left sides (or right) bloop.Pass through this of bloop
It is kind interlaced to configurate, repeatedly refraction or diffraction can be produced to noise, so as to cut down the energy of noise, reduce into
Enter the possibility to next industrial equipment, improve the isolation of its noise.
Muffler air inlet is provided with noise reduction mesh, so improve the advantages of be the various industrial impurity in cement plant and insect etc.
Debris is not easily accessible in blower fan.
Inlet and outlet both ends dig the installed part groove of energy inlay card peripheral hardware industrial equipment, closer with industrial equipment installation,
It is better.
Silencing cotton is using ultrafine slag cotton, mineral wool, glass fiber, industrial felt porous sound absorbing materials.The thickness of deadener
Degree can select according to the frequency of noise, and thicker deadener suppresses high-frequency noise, and deadener thickness hour is to all-bottom sound
Assimilation effect it is preferable.
There is noise reduction gap between silencing cotton and installed part, be to be used to change silencing cotton, the reason such as prevent silencing cotton outmoded
Cause erasure effect low.Providing for simple replacement of for silencing cotton is realized, muffler is repeatable to be utilized, and saves operating cost.
Position of the housing in addition to air outlet and air inlet is in closed.
Air inlet, air outlet position can be with slightly requirement changes.
The utility model has the advantages that：The center line of air inlet and the center line of air outlet are into 90 degree of angles and left and right phase
Mutually the design of staggered bloop reduces the energy of noise significantly so that muffler acoustic attenuation performance is excellent；Silencing cotton is adopted
With porous compound deadener, different materials and thickness can be selected according to the frequency of noise；What muffler air inlet was set disappears
The installed part groove part of sound mesh and inlay card peripheral hardware industrial equipment is suitable for the harsh environments in cement plant；Noise reduction gap
Setting realizes providing for simple replacement of for silencing cotton, and muffler is repeatable to be utilized, and saves operating cost.

Embodiment
It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model
Explanation.
A kind of cement plant muffler of the utility model, including silencing net 3, silencing cotton 2 and shell 1；Silencing cotton 2 is arranged on
Between shell 1 and silencing net 3, shell 1, silencing cotton 2 and silencing net 3 are set in parallel.
The housing 1 is arranged to cuboid-type.The left side wall of silencer casing 1 is provided with air inlet in the position close to top
5, outer casing bottom is provided with air outlet 4 so that the center line of air inlet 5 and the center line of air outlet 4 into 90 degree of angles, this
Sample, after sound wave enters the muffler inside, head-on crash will occur with inner walls, and then turn to move downward.Sound wave with
Head-on crash between inner walls quieter material, the uptake of sound wave can be increased, is more beneficial for noise reduction.
Left side wall and right side wall are respectively arranged with several bloops 8, several left bloops and several right bloops
Mutually be staggered arrangement on the left and right directions and above-below direction of muffler, is arranged in array respectively in left wall and right wall
On, each left (or right) bloop is between neighbouring two left sides (or right) bloop.Pass through bloop
It is this it is interlaced configurate, can to noise produce repeatedly refraction or diffraction, so as to cut down the energy of noise, reduce
The possibility of next industrial equipment is entered, improves the isolation of its noise.
Muffler air inlet is provided with noise reduction mesh 7, so improve the advantages of be the various industrial impurity in cement plant and insect
It is not easily accessible Deng debris in blower fan.
Inlet and outlet both ends dig the installed part groove 6 of energy inlay card peripheral hardware industrial equipment, closer with industrial equipment installation,
It is better.
Silencing cotton 2 is using ultrafine slag cotton, mineral wool, glass fiber, industrial felt porous sound absorbing materials.The thickness of deadener
Degree can select according to the frequency of noise, and thicker deadener suppresses high-frequency noise, and deadener thickness hour is to all-bottom sound
Assimilation effect it is preferable.
There is noise reduction gap 9 between silencing cotton 2 and installed part 6, be to be used to change silencing cotton 2, prevent silencing cotton 2 outmoded etc.
Reason causes erasure effect low.Providing for simple replacement of for silencing cotton 2 is realized, muffler is repeatable to be utilized, and saves operating cost.
Position of the housing in addition to air outlet 4 and air inlet 5 is in closed.
Air inlet 5, the position of air outlet 4 can be with slightly requirement changes.
The air outlet of the air inlet 4 of the muffler and blower fan is docking together by installed part groove 6, it is outside in blower fan
During exhaust, the air arranged takes sound wave and enters muffler air inlet 4；Noise reduction mesh 7 hinders the various industrial impurity in cement plant
With the various debris such as insect；Sound wave runs into the quieter material in inner walls, and partial noise will be absorbed by quieter material, simultaneously
The side wall that air-flow runs into housing with acoustic streaming reflects, and becomes to flow downward by original bottom horizontal flow sheet, part in flow process
Bloop 8 of the noise again by the interlaced arrangement of the silencing cotton 2 in inner walls and left and right absorbs, and has thus reached reduction
The effect of fan noise pollution.After silencing cotton 2 is outmoded, it can be changed by the noise reduction gap 9 between silencing cotton 2 and installed part 6.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
