Description
Technical field
Aeration technology field is the utility model is related to, specifically, is related to a kind of Jing Yin pipeline fan.
Background technology
Pipeline fan is that one kind is widely used in industrial premises, building building, room ventilation ventilation or pipeline pressurization
Ventilation equipment；Traditional pipeline fan due to structure design not very rationally, the problem of causing it to be primarily present is：Blower fan sheet
Body does not have decrease of noise functions substantially, during fan operation, due to being influenceed by windage, can produce great noise, now
Generally require and muffler is installed on ventilation shaft to coordinate blower fan to carry out noise reduction, so substantially increase construction and installation
The complexity of cost and ventilation shaft.Meanwhile also there is complicated, site operation installation inconvenience etc. and ask in existing blower fan
Topic.
Utility model content
The purpose of this utility model can carry out noise reduction to provide a kind of Jing Yin pipeline fan to blower fan, easy for installation, and into
This is low.
To achieve these goals, Jing Yin pipeline fan provided by the utility model include casing, air inlet, air outlet,
And the impeller in casing and the motor of driving wheel rotation, air inlet are arranged on relative the two of casing with air outlet
Side；Casing includes inner and outer wall, has the cavity for accommodating quieter material between inner and outer wall；Inner and outer wall is by distribution
The acoustical panel for having some bloops is made；One layer of thin sound-absorbing material is pasted with outer wall in cavity, is pasted on inwall
With one layer of thick sound-absorbing material；Some bloops are distributed with the thin at least one layer that is placed between sound-absorbing material and thick sound-absorbing material
Noise reduction wave-shape board；Crest or trough positioned at noise reduction wave-shape board in cavity are provided with the locating rod for being used for fixing noise reduction wave-shape board.
Specific scheme is more than the aperture of the bloop of noise reduction wave-shape board for the aperture of the bloop of inwall；Noise reduction wave-shape board
Bloop aperture be more than outer wall bloop aperture.
Another specific scheme is more than the porosity of thin sound-absorbing material for the porosity of thick sound-absorbing material.
Another specific scheme is the both sides that two neighboring locating rod is located at noise reduction wave-shape board respectively.
Another specific scheme between two neighboring locating rod at least between be separated with wave week of noise reduction wave-shape board
Phase.
Compared with prior art, the beneficial effects of the utility model are：
Jing Yin pipeline fan of the present utility model has good noise reduction, easy for installation, and cost is low.

In 01.
Casing 01 includes inwall 1 and outer wall 2, has the cavity for accommodating quieter material, the He of inwall 1 between inwall 1 and outer wall 2
Outer wall 2 is made up of the acoustical panel that some bloops are distributed with.
In cavity between inwall 1 and outer wall 2, one layer thin sound-absorbing material 4 is pasted with outer wall 2, positioned at inwall 1
On be pasted with one layer of thick sound-absorbing material 3.One layer is placed between thin sound-absorbing material 4 and thick sound-absorbing material 3, and some bloops are distributed with
Noise reduction wave-shape board 5.
In order to reach more preferable erasure effect, the aperture of the bloop of inwall 1 is more than the hole of the bloop of noise reduction wave-shape board 5
Footpath, the aperture of the bloop of noise reduction wave-shape board 5 are more than the aperture of the bloop of outer wall 2, in addition, the porosity of thick sound-absorbing material 3
More than the porosity of thin sound-absorbing material 4.
In order that noise reduction wave-shape board 5 can be preferably fixed between thick sound-absorbing material 3 and thin sound-absorbing material 4, in noise reduction
The locating rod 6 for being used for fixing noise reduction wave-shape board 5 is provided with the crest or trough of wave-shape board 5, two neighboring locating rod 6 is located at respectively
The both sides of noise reduction wave-shape board 5, and a wave period of noise reduction wave-shape board 5 is spaced between two neighboring locating rod 6.
Preferable implementation example of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this reality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
