Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, a noise elimination integrated pipeline fan includes a machine body 1 and a noise elimination pipe 8, where the noise elimination pipe 8 includes a pipe center 7, a pipe peak 6 and a pipe tail 4, the pipe peak 6 is disposed at both ends of the pipe center 7, the pipe tail 4 is disposed at an outer end of the pipe peak 6, the pipe center 7, the pipe peak 6 and the pipe tail 4 are integrated, the machine body 1 is disposed in the pipe center 7, an impeller 14 is disposed inside the machine body 1, a noise elimination plate 9 is disposed in the pipe peak 6, a noise elimination ring 3 and a honeycomb plate 10 are disposed in the pipe tail 4, and the honeycomb plate 10 is located inside the noise elimination ring 3.

Further, a plurality of fixing blocks 5 are fixed on the outer side of the pipe peak 6, connecting holes 13 are formed in the fixing blocks 5, the silencing plate 9 is of a concave-convex structure, the silencing plate 9 is made of sponge, a damping pad 2 is arranged between the machine body 1 and the silencing pipe 8, a rubber pad 12 is arranged on the inner side of the pipe tail 4, and a plurality of hole grooves 11 are formed in the outer side of the silencing ring 3.

Specifically, the damping pad 2 is arranged on the outer side of the machine body 1, so that the noise is reduced, the machine body 1 produces sound due to vibration during working, meanwhile, when the impeller 14 rotates, wind noise is generated and is emitted from the machine body 1, the wind noise presents a diffusion state in the pipe peak 6, the wind noise is absorbed through the damping plate 9, then the pipe orifice of the pipe tail 4 is contracted, so that the residual sound is gathered, the sound is effectively absorbed through the honeycomb plate 10 again, the gathering structure improves the sound absorption efficiency, finally, the hole grooves 11 are formed in the silencing ring 3, the residual wave is absorbed again, and meanwhile, the silencing ring 3 plays a role in fixing the honeycomb plate 10.
