Abstract
The utility model provides an ultralow noise fan for tunnel construction, has noise elimination material, its characterized in that including side air inlet muffler 1, anti -coagulating action formula reflection muffler, host computer between the shell of host computer, the inner shell: anti -coagulating action formula reflection muffler comprises shell, inner shell, acoustical panel, and it has the noise elimination material to fill between shell, the inner shell, before the inner shell interior division in, the back three -section installs the acoustical panel respectively, and the acoustical panel vertical installation in middle section, the acoustical panel of anterior segment and back end is transversely installed respectively, the beneficial effects are that: adopting the acoustical panel that alternaties anyhow to form anti -coagulating action formula reflection passageway, having changed fan noise propagation way, acoustic energy rubs in porous material's acoustical panel space and changes heat energy into and dissipate to reach the noise elimination mesh, obtained better the noise reduction effect, reduced to 69dB ordinary fan 120dB's noise is higher.
Description
Technical field
The utility model is related to a kind of tunnel blower fan, and in particular to a kind of super low noise constructing tunnel blower fan.

At present, the engineerings such as the subway that city is built, people's air defense constantly increase, and construction ventilation is extremely important, and especially blower fan is made an uproar
Sound directly affects city environmental quality, and existing blower fan erasure effect needs further raising.
The content of the invention
The purpose of this utility model is exactly that prior art is improved, and provides a kind of super low noise constructing tunnel wind
Machine.
To achieve these goals the technical solution adopted in the utility model is：A kind of super low noise constructing tunnel wind
Machine, including side suction silencer, anti-coagulating action formula reflection muffler, main frame, have deadener between shell, the inner casing of main frame, eliminate the noise
Material is superfine glass silk flosssilk wadding, it is characterised in that：The anti-coagulating action formula reflection muffler is made up of shell, inner casing, acoustical panel, outward
Deadener is filled between shell, inner casing, deadener is superfine glass silk flosssilk wadding, and three sections are respectively mounted before, during and after interior point of inner casing
Acoustical panel, the acoustical panel in stage casing is vertically installed, and the acoustical panel of leading portion and back segment is transversely mounted respectively, the deadener of acoustical panel by
Orifice plate Coated glass silk flosssilk wadding system is formed.
A kind of super low noise constructing tunnel blower fan in accordance with the above, it is characterised in that：The main frame and anti-coagulating action formula
Deadener between shell, the inner casing of reflection muffler is foaming deadener；The deadener of described noise elimination wall is to send out
Bubble deadener is fixed by steel plate lead frame.
Compared with prior art, the beneficial effects of the utility model are：Anti-coagulating action formula is formed using the acoustical panel for converting anyhow
Reflection channel, changes fan noise route of transmission, and acoustic energy rubs in the acoustical panel space of porous material and changes into heat energy
Dissipate, so as to reach noise elimination purpose；More preferably noise reduction is obtained, is reduced to the noise of common blower fan 120dB is higher
69dB.

There is deadener 7 between shell, inner casing, deadener is superfine glass silk flosssilk wadding, and each company is distinguished in the inlet side of main frame 3 and air side
An anti-coagulating action formula reflection muffler 2 is connect, the present embodiment main frame 3 lists two-stage to revolving main frame, and compared to existing technology this practicality is new
The anti-coagulating action formula that type provides reflects muffler 2, and the anti-coagulating action formula reflection muffler 2 is made up of shell 4, inner casing 5, acoustical panel 6, shell
4th, deadener 7 is filled between inner casing 5, deadener is superfine glass silk flosssilk wadding, is pacified respectively for three sections before, during and after interior point of inner casing 5
Dress acoustical panel 6, the acoustical panel 6 in stage casing is vertically installed, and Fig. 2 is anti-coagulating action formula reflection muffler stage casing A-A profiles；Leading portion and back segment
Acoustical panel 6 be transversely mounted respectively, Fig. 3 is anti-coagulating action formula reflection muffler leading portion B-B profiles, back segment C-C profiles and leading portion
B-B profiles are identical；The deadener of acoustical panel 6 is formed by orifice plate Coated glass silk flosssilk wadding system.
The anti-coagulating action formula reflection muffler 2 that the utility model is provided, using the acoustical panel 6 for converting anyhow the reflection of anti-coagulating action formula is formed
Passage, changes fan noise route of transmission, and acoustic energy rubs in the space of acoustical panel 6 of porous material and changes into thermal dissipation
Fall, so as to reach noise elimination purpose；More preferably noise reduction is obtained, is reduced to the noise of common blower fan 120dB is higher
69dB。
A kind of super low noise constructing tunnel blower fan embodiment in accordance with the above, the main frame 3 and anti-coagulating action formula reflect
Deadener between shell 4, the inner casing 5 of muffler is foaming deadener；The deadener of described noise elimination wall 19 is to send out
Bubble deadener is fixed by steel plate lead frame.
Main frame described in a kind of super low noise constructing tunnel blower fan of the utility model can also be single-stage or multistage.
The anti-coagulating action formula reflection muffler 2 that a kind of the utility model super low noise constructing tunnel blower fan is provided, can also use
With other blower fans.
