Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is required attached drawing in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention
Some embodiments for those of ordinary skill in the art without creative efforts, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of the invention；
Fig. 2 is the left view structural representation of Fig. 1.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, a kind of rectangular array cylindricality fans silencer provided in this embodiment, including silencer tube body 8,
The upstream end of silencer tube body 8, which is equipped with, exports the air inlet abutted flange 1 docked with ventilation blower, sets in the outlet end of silencer tube body
There is the outlet air abutted flange 7 docked with air hose, contracts close to one end of outlet air abutted flange equipped with outlet air variable diameter in silencer tube body
Segment is equipped with the air inlet variable diameter expanding reach for guaranteeing flow area, air inlet in silencer tube body close to one end of air inlet abutted flange
The silencer tube body that variable diameter expanding reach and outlet air variable diameter reduce between section is set as noise elimination direct tube section, in the noise elimination of noise elimination direct tube section
One circle of installation prevents the inner wall sound arrester 5 of secondary noise on device inboard wall of tube body, in the silencer tube body of noise elimination direct tube section
Inside is equipped with several noise elimination columns 4 being fixedly connected by mounting rack and silencer tube body, the space setting between adjacent noise elimination column
To enter the wind silencers channel, the axial direction of the axial direction and silencer tube body of the noise elimination column is arranged in parallel, in noise elimination column
Both ends end is equipped with the water conservancy diversion circular arc 3 for avoiding generating wind-dryness, and the noise elimination column is column muffler plate, in the outer of column muffler plate
Wall is equipped with several noise elimination through-holes, is filled with glass sound-absorbing cotton in the inside of column muffler plate, disappears in glass sound-absorbing cotton and column
One layer of fiber cloth is equipped between the inner wall of sound plate.The mounting rack is divided into front and back mounting rack, and the preceding setting of mounting rack 2 is in air inlet variable diameter
Expanding reach and noise elimination direct tube section junction, the setting of 6 framves of rear installation reduces section and noise elimination direct tube section junction in outlet air variable diameter, described
Forward and backward mounting rack is cross mounting rack.The noise elimination column 4 is evenly distributed on the silencer tubular body of noise elimination direct tube section.This
Invention is using the air inlet silencers channel between adjacent noise elimination column, so that air inlet enters disappearing for column muffler plate along air inlet silencers channel
Sound through-hole, to realize noise control, by noise control at 85 decibels hereinafter, reduce influence of the strong noise to staff,
And then improve the working efficiency of staff；Using the water conservancy diversion circular arc being mounted at noise elimination column air intake, air inlet impact can avoid
Noise elimination column generates secondary wind-dryness；Using the inner wall sound arrester being mounted on silencer inboard wall of tube body, it can prevent air inlet impact from disappearing
The secondary noise that sound device inboard wall of tube body generates, ensure that sound-absorbing effect.Between the wind that the blower generates refers to from column muffler plate
It enters the wind silencers channel to enter, enter through water conservancy diversion circular arc from the two sides noise elimination through-hole of noise elimination column, a part of wind-dryness passes through glass sound-absorbing
Cotton absorbs, some is offset by convection current between wind and wind, after noise elimination after be discharged along the outlet end of silencer tube body.
The noise elimination direct tube section of the silencer tube body reduces section with air inlet variable diameter expanding reach, outlet air variable diameter and smoothly connects, institute
It states noise elimination direct tube section, air inlet variable diameter expanding reach, the diminution section design of outlet air variable diameter to be integrated, be improved using air inlet variable diameter expanding reach logical
