Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
Fig. 1 is a perspective view of a noise absorbing device of the present invention; fig. 2 is a cross-sectional view of a noise absorbing device of the present invention; fig. 3 is a schematic view illustrating the flow of the air flow of the noise absorbing device of the present invention.
Referring to fig. 1-3, there is shown a preferred embodiment of a noise absorbing device comprising:
an iron box 1.
The screen plate box 2 is arranged in the iron box 1, and the silencing cotton 3 is filled between the shell of the screen plate box 2 and the iron box 1.
Three partition plate groups, each partition plate group comprising two partition plates 41 arranged in parallel; the three partition plate groups are arranged in the mesh plate box 2 at equal intervals along the length direction of the mesh plate box 2; the inside of the net board box 2 is divided into a first compartment 21, a second compartment 22, a third compartment 23 and a fourth compartment 24 from left to right by three partition plate groups; an air inlet 241 is disposed at the fourth compartment 24.
A first air duct 5, the first air duct 5 communicating the second compartment 22 and the fourth compartment 24.
And a second air duct 6, the second air duct 6 communicating the first compartment 21 and the third compartment 23.
And a third air duct 7, wherein the third air duct 7 is communicated with the second compartment 22 and the third compartment 23.
The above is merely an example of the preferred embodiments of the present invention, and the embodiments and the protection scope of the present invention are not limited thereby.
