In the case of purpose is that solution silencer appearance and size is certain, the contact area of noise elimination face and air-flow is small, and soundproof effect is bad
Problem.
To achieve these goals, the utility model provides a kind of matrix form silencer, including housing and muffling unit mould
Block；
Wherein, the housing includes three-decker, and one layer of outermost is steel plate, and most one layer of the inside is perforated plate, the steel
Sound-absorbing material is provided between plate and perforated plate；
The muffling unit module is multiple, and each muffling unit module is column structure, and end face is in " returning " font,
Each muffling unit module is evenly distributed in the housing in parallel to each other, and is in matrix arrangement；
Space and the muffling unit between the muffling unit module, between muffling unit module and the housing
Space among module collectively constitutes the silencing channel of silencer, for consuming flowed energy, reduces noisiness, realizes and eliminate the noise.
Further, the muffling unit module is hollow structure, and its surfaces externally and internally is perforated plate, is filled out between surfaces externally and internally
Filled with sound-absorbing material.
Further, the silencer also includes connecting rod and fixing screws, between each muffling unit module, eliminate the noise it is single
Realized and connected by the connecting rod between element module and housing, and fixed by the fixing screws.
Further, the end of the muffling unit module is provided with end socket, and the end socket is provided with bolt hole, for realizing
State the connection of muffling unit module and connecting rod.
In general, by the contemplated above technical scheme of the utility model compared with prior art, can obtain down
Row beneficial effect：
(1) silencer of the present utility model, muffling unit module end face are in " returning " font, considerably increase air-flow with eliminating the noise
The contact area in face, increase pass through flow area, reduce air velocity, reduce regenerated noise magnitude, increase sound deadening capacity, achieve
Good soundproof effect.
(2) silencer of the present utility model, housing are three-decker, and outermost is steel plate, and centre is sound-absorbing material, most in
One layer of face is perforated plate, increase air-flow and noise elimination face contact area, reduces air velocity so as to reduce noisiness.
(3) silencer of the present utility model, it is connected each muffling unit module by connecting rod, simple in construction, installation
Convenient disassembly, if some muffling unit module failure can be with quick replacement.
(4) silencer of the present utility model, it is perforated plate inside and outside muffling unit module, inside filling sound-absorbing material, disappears
Gas consumption stream energy, reduce noisiness.
