Abstract
The utility model discloses a multi-dimensional silencing device and relates to multi-dimensional silencing equipment. According to the characteristic that noise is propagated in a sound wave form commonly, the multi-dimensional silencing device is fixed through supporting grid installation frames; one of the supporting grid installation frames is arranged on a sound wave propagation route fan pipeline, and after the multi-dimensional silencing device abuts against the installed supporting grid installation frame and is put in place, the other supporting grid installation frame is arranged on the other side of the multi-dimensional silencing device; the multi-dimensional silencing device is divided into a flow equalizing section and a silencing section; in the flow equalizing section, a plurality of trihedral structures parallel to the pipeline are encircled by a PVC (polyvinyl chloride) supporting plate and a PVC guide refraction plate; in the silencing section, an irregular polyhedron structure is encircled by the PVC supporting plate and the PVC guide refraction plate; micro holes of which the diameter phi is 2-5mm are formed in the PVC guide refraction plate; the multi-dimensional silencing device is integrated by the flow equalizing section and the silencing section. The multi-dimensional silencing device has the positive effects of simple structure, low manufacturing cost, convenience in installation, labor conservation, time conservation and obvious noise reduction effect; the noise reduction effect can reach 3-15dB(A), and the harm to a human body caused by the noise is reduced.
Description
Technical field
The utility model relates to a kind of multidimensional silencing equipment.
Background technique
Along with social development and the raising of living standards of the people, noise pollution and harm more and more receive people's concern.Traditional noise-eliminating device for air-blower is, on the pipe wall of carrying at air quantity, mesh type silencing pot is set at present, inside fills the cotton of eliminating the noise.The silencer of this class formation can only be decayed to the noise sound wave along pipe transmmision, the most noises of air duct central authorities of cannot decaying, and then bring erasure effect not obvious, do not reach the problems such as designing requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of multidimensional silencer, solve can only decaying to the noise sound wave along pipe transmmision of prior art existence, the central most noises of the air duct of cannot decaying, and then bring erasure effect not obvious, do not reach the problems such as designing requirement.
The utility model is mainly comprised of conduit component and silencer, solving the technological scheme that its technical problem adopts is to be generally the feature of propagating with sound wave form for noise, silencer adopts and supports lattice coral scaffold means of fixation, on Acoustic Wave Propagation approach Fan pipeline, arrange and support lattice coral scaffold, by multidimensional silencer near mounted support lattice coral scaffold, place after multidimensional silencer, at multidimensional silencer opposite side, refill a support lattice coral scaffold.Multidimensional silencer is divided into flow equalization section and muffler section, its erection sequence be flow equalization section front, muffler section is rear (making reference with noise transmission direction); Multidimensional silencer comprises PVC dunnage, PVC guiding refraction plate, adhesive layer; Flow equalization section surrounds multiple thrihedron structures that are parallel to pipeline by PVC dunnage and PVC guiding refraction plate, muffler section surrounds irregular polyhedrons structure by PVC dunnage and PVC guiding refraction plate, PVC support plate, PVC guiding refraction plate form adhesive layer by Bond, the PVC guiding refraction plate micropore that φ 2-5mm is set on PVC guiding refraction plate, flow equalization section and muffler section integrate composition multidimensional silencer.
Adopt the good effect of this multidimensional silencer to be:
1, simple in structure, fabricating cost is low.The parts that this structure adopts are less, comprise and support lattice coral scaffold and multidimensional noise elimination core component;
2, easy for installation, through simply confiding a technological secret, just can operate, without special professional skill training, saving of work and time;
3, noise reduction is obvious, can reach 3-15dB (A) noise reduction, reduces noise to harm.

Embodiment
As shown in the figure; It for noise, is generally the feature of propagating with sound wave form, on Acoustic Wave Propagation approach Fan pipeline 1, arrange and support lattice coral scaffold 2, by multidimensional silencer near mounted support lattice coral scaffold 2, put well after multidimensional silencer, at device opposite side, refill a support lattice coral scaffold 2.Multidimensional silencer is divided into flow equalization section and muffler section, the erection sequence of multidimensional silencer be with air-flow as reference direction flow equalization section front, muffler section is rear; Multidimensional silencer comprises PVC dunnage 3, PVC guiding refraction plate 4, adhesive layer 5; Flow equalization section surrounds multiple thrihedron structures that are parallel to pipeline 1 by PVC dunnage 3 and PVC guiding refraction plate 4, muffler section surrounds irregular polyhedrons structure by PVC dunnage 3 and PVC guiding refraction plate 4, one deck PVC support plate 3, one deck PVC guiding refraction plate 4 form adhesive layer 5 by Bond, φ 4mmPVC guiding refraction plate micropore 6 is evenly set on PVC guiding refraction plate 4, and flow equalization section and muffler section integrate composition multidimensional silencer.
During work, when air-flow and noise are during by this multidimensional silencer, air-flow and noise first pass through the flow equalization section of multidimensional silencer, are also the introduction segments of air-flow and noise, its objective is and guarantee that air-flow and noise flow field are uniformly distributed, and prevent that eddy current from producing.Air-flow and noise enter muffler section after by flow equalization section, muffler section has on multistage refraction plate and refraction plate micropore is set, air-flow and noise pass under the effect of micropore at refraction and the sound wave of multistage flap, make sound wave-amplitude decay gradually and reduce, and guarantee that air-flow passes through simultaneously.This device is mainly applicable to the noise producing while subduing blower fan delivery air, also can be used for subduing the noise that miscellaneous equipment produces.
