Description
Technical field
This utility model is related to acoustic filter field, more particularly to a kind of foamed aluminium array type silencer.
Background technology
Acoustic filter is to allow air-flow to pass through, but can prevent or reduce a kind of device of sound transmission, is to eliminate air to move
The important measures of power noise.Acoustic filter can when air-flow passes through energy absorption, be control noise effective tool.
The muffler part of traditional impedance muffler is mainly using adding sound-absorbing material to make in porous plate, noise elimination portion
Part is fixed on the inwall of gas channel or arranges muffler part according to certain way in the duct, just constitutes resistance noise reduction
Device.When sound wave enters dissipative muffler, a part of acoustic energy rubs in the hole of porous material and changes into thermal dissipation
Fall, make to weaken by the sound wave of acoustic filter.Dissipative muffler just looks like pure resistor element circuit electrically, and deadener is similar to electricity
Resistance.Therefore, people just call dissipative muffler this acoustic filter.Dissipative muffler is good to medium-high frequency soundproof effect, to low frequency
Soundproof effect is poor.
Prior art generally adopts conventional centrifugally glass-wool as sound-absorbing material, as glass cotton is by a large amount of glass fiber
Composition, after using certain time limit, there is the risk that glass fiber leaks.
Utility model content

By such scheme, muffling unit module sets up and is fixed on column, some muffling unit modular matrix formula arrangements,
Detachable to assemble, easy for installation, convenient to transport, between muffling unit module, equal interval setting, can give air sufficiently large
The flowing space；Foamed aluminium has the function of good sound insulation and noise reduction, and which absorbs, and impact capacity is strong and fire protecting performance is strong, using peace
Entirely, while the drawbacks of glass fiber that it also avoid being produced using glass cotton is leaked.
Further, the column in one of them described muffling unit module group includes being fixed on connected entrance one or connected entrance
The fixing end of two upper and lower and the movable part between two fixing ends, are provided with activity on the outside of the movable part
Door, the dodge gate side are hinged on movable part, and opposite side is hinged on the adjacent column of movable part, and two dodge gates
Positioned at the homonymy of two movable parts.
By such scheme, dodge gate side is hinged on the adjacent column of movable part, so as to dodge gate can be around this
Column horizontally rotates, and the opposite side of dodge gate is hinged on movable part, so as to dodge gate can be rotated around movable part, and two
Muffling unit module between individual movable part is supported by dodge gate；It is hinged on movable part when dodge gate is pulled out
During side, dodge gate can be moved to adjacent column with muffling unit module, and the motion outside simultaneous to housing, from
And movable part is formed into the passage for being available for people to pass through away from the gap enlargement of dodge gate side, it is easy to staff logical into this
Detected in road and keeped in repair.
Further, being horizontally disposed with some columns in the connected entrance one and connected entrance two has crossbeam, the horizontal stroke
Beam is located in housing under the muffling unit module of the top and the fixing end in top is fixedly connected on crossbeam.
By such scheme, crossbeam is used for the stability for strengthening column, and horizontal depth of beam is set according to the height of people, crossbeam
It is below the passage entered for people, fixing end is fixedly connected with crossbeam, for the fixed muffling unit module for weighing the above.
Further, the Circulation Area for being easy to air flow is opened up in the middle part of the dodge gate.
By such scheme, Circulation Area in the middle part of dodge gate, is opened, a dodge gate actually doorframe, so as to facilitate air in dodge gate
The circulation at place.
Further, the muffling unit module two ends are provided with fair water cone, the fair water cone be in quadrangular frustum pyramid shaped and its four
Individual side wall is outwardly cambered surface, and the top surface of the fair water cone is fixed on column.
By such scheme, muffling unit module two ends are covered by fair water cone, are then attached on column, arc surfaced
Fair water cone can reduce the drag losses of fair water cone, be conducive to lifting the overall performance of array type silencer.
In sum, this utility model has the advantages that：
1st, arranging some muffling unit modular matrixs in housing carries out noise elimination noise reduction, and muffling unit module is erected at column
Between, dismounting facility is convenient to keep in repair；
2nd, the muffling unit module on movable part can be to a side shifting, so as to the gap enlargement of movable part opposite side is formed
The passage for being available for people to enter, is easy to maintainer to enter maintenance.
