Description
Technical field
The utility model relates to a kind of improvement of the structure of air blower.
Background technique
Air blower is the commonly used equipment in the fields such as sewage treatment, electric power, petroleum, cement.However due to host, driving motor
With the presence of the components such as air ejector fan, noise is very high when air blower being caused to use, and wherein the noise of Roots blower may be up to
150 decibels, this is affected to environment, does not also meet the requirement of national environmental protection.
Therefore how noise is effectively reduced, is the application technical problems to be solved.
Utility model content
The purpose of this utility model is in order to overcome the problems referred above, to propose a kind of sound-insulating structure of air blower, pass through muffler
Noise is obtained when can reduce equipment operation with whole blimp.
A kind of sound-insulating structure for air blower that the utility model is proposed, including host and its driving motor, feature exist
In:
Host and driving motor are fixed on hollow base surface, the complete machine blimp outside base connection；Complete machine sound insulation
Compressed gas exhaust passage and inlet channel are distributed in cover, in which:
Compressed gas exhaust passage is located at host side, and one end connects the reserved gas outlet in complete machine blimp surface, separately
One end connects host by exhaust silencer；
Inlet channel is located at the host other side, and one end connects the reserved air inlet in complete machine blimp surface, and the other end is logical
Cross admission air silencer connection host.Barrier absorption, Ke Yiyou are carried out to the noise of host head using air inlet and muffler
The noise air blower of effect is generally reduced to 90 decibels from 120 decibels.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines diagram, and above-mentioned technical proposal is further described.
A kind of sound-insulating structure of air blower as shown in the figure, including host 2 and its driving motor 4, it is characterised in that:
Host 2 and driving motor 4 are fixed on hollow base surface, the complete machine blimp 7 outside the base connection；It is whole
Compressed gas exhaust passage 9 and inlet channel 5 are distributed in machine blimp 7, in which:
Compressed gas exhaust passage 9 is located at 2 side of host, and one end connects the reserved gas outlet in 7 surface of complete machine blimp,
The other end connects host 2 by micropunch formula exhaust silencer；
Inlet channel 5 is located at 2 other side of host, and one end connects the reserved air inlet in 7 surface of complete machine blimp, the other end
Host 2 is connected by micropunch formula intake muffler.
Further, the inner wall of exhaust passage, inlet channel 5 and complete machine blimp 7 is pasted with double-layer combined respectively
Sound-isolating sponge specifically includes high-density sponge layer and low-density sponge layer, and wherein high-density sponge layer can be effectively to air blast
The high frequency noise of machine carries out barrier reflection, makes high frequency noise that can not transfer out the external world, decays in blimp internal reflection, in addition
One layer of low-density sponge layer can carry out absorption dissipation to low frequency noise.
Further, the lateral soundproof plate 10 and longitudinal soundproof plate 10 of one piece of connection complete machine blimp 7 is arranged in base tail portion,
Wherein lateral soundproof plate 10 separates inlet channel 5 and exhaust passage, and longitudinal soundproof plate 10 is located at 3 side of admission air silencer,
Several oblique soundproof plates 10 positioned at 4 tail portion of driving motor are arranged in parallel in side, and one carrys out control noise dispersal direction, guarantee noise
It double-layer combined sound-isolating sponge can be passed through when diffusion, reduces the validity of noise, two form labyrinth structure, are passing through noise
Out-of-date decaying.
Further, exhaust fan 8 is set to 1 side of muffler, connects complete machine blimp 7 by thermal exhaust channel 6
The reserved thermal exhaust mouth in surface.Soundproof plate 10 is set between exhaust fan 8 and muffler 1, and the tail portion of soundproof plate 10 is close to whole
Machine blimp 7 guarantees that thermal current can be extracted out by exhaust fan 8, into heat exhaust tube.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model
There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted
Protection scope is asked to be defined by appended claims and its equivalent.
