Description
Technical Field
The invention belongs to the field of fans, and particularly relates to a pipeline high-temperature axial flow fan with a noise reduction function.
Background
The high-temperature fan belongs to a special fan, is specially used in high-temperature operation places, and is made of materials with strong high temperature resistance and high pressure resistance. The high-temperature fan mainly comprises: stainless steel high temperature resistant fan, transmission high temperature fan, centrifugal high temperature fan, etc. The high-temperature fan is widely applied to the fields of chemical industry, petroleum, metallurgy, forging and pressing, electric power, nuclear power plants, environmental protection and the like. Along with the improvement of living standard of people, the requirement of people on the working environment is higher and higher, the function of the old and practical fan is mainly considered during the design, the influence of the old and practical fan on the environment is not considered, and the old fan can generate a large amount of noise in the operation process, thereby not only influencing the health of workers, but also forming noise pollution on the surrounding environment and influencing the urban landscape.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a pipeline high temperature axial fan with amortization function.
The utility model discloses technical scheme as follows: a pipeline high-temperature axial flow fan with a noise reduction function comprises an axial flow fan, a silencer, a bottom frame and a rubber vibration isolator, and is characterized in that the axial flow fan is connected with the silencer and is connected with the bottom frame, the rubber vibration isolator is mounted on the bottom frame, vibration and noise are reduced, the axial flow fan comprises a motor, a belt outer cover, a belt, fan blades, a pipeline and a rotating shaft, the motor drives the rotating shaft through the belt so as to enable the fan blades to rotate, the belt outer cover covers the belt, meanwhile, the belt outer cover is made of a mute material, noise is reduced, the resistive silencer utilizes acoustic resistance to eliminate noise, the resistive silencer is usually made of the sound absorption material, when sound waves pass through the pipeline lined with the porous sound absorption material, the sound waves excite the vibration of air molecules in countless pores in the porous material, and a part of the sound energy is used for overcoming friction resistance and viscous force and changing into heat energy, therefore, the purposes of absorbing sound energy and reducing noise are achieved, the silencer can reduce the noise generated when gas flows through the pipeline, and the noise of the blades is reduced by adopting noise reduction structures such as additional sawteeth, vortex generators, porous structures and the like. The fan blades and rotating parts such as the rotating shaft and the like are subjected to strict static balance and dynamic balance correction.
The utility model has the advantages that: compare with traditional old-fashioned fan, the fan optimize the upgrading to the fan through many-sided multi-angle such as rubber vibration isolator, silence belt dustcoat, muffler, silence blade at the operation in-process, the fan that has significantly reduced produces the noise at the operation in-process, creates a low-noise operational environment for the workman, also greatly reduced to peripheral noise influence.

Fig. 1 is a schematic view of the local organization structure of the present invention.
Reference numerals: the device comprises a motor 1, a belt outer cover 2, an axial flow fan 3, a silencer 4, a rubber vibration isolator 5 and a bottom bracket 6.
Detailed Description
As shown in the attached figure 1, a pipeline high-temperature axial flow fan with a noise reduction function comprises an axial flow fan (3), a silencer (4), a bottom frame (6) and a rubber vibration isolator (5), and is characterized in that the axial flow fan (3) is connected with the silencer (4) and connected with the bottom frame (6), the rubber vibration isolator (5) is installed on the bottom frame (6) to reduce vibration and noise, the axial flow fan (3) comprises a motor, a belt outer cover, a belt, blades, a pipeline and a rotating shaft, the motor drives the rotating shaft by the belt to enable the blades to rotate, the belt outer cover (2) covers the belt to reduce noise, the resistive silencer utilizes acoustic resistance to eliminate noise, the resistive silencer is usually made of sound absorption materials, when sound waves pass through the pipeline lined with porous sound absorption materials, the sound wave excites the vibration of air molecules in countless pores in the porous material, wherein a part of sound energy is used for overcoming friction resistance and viscous force and is converted into heat energy, so that the purposes of absorbing the sound energy and reducing noise are achieved, the noise generated by the silencer (4) can be reduced when gas flows through a pipeline, and the noise of the blade is reduced by adopting noise reduction structures such as additional sawteeth, vortex generators, porous structures and the like on the mute blade. The fan blades, the rotating shaft and other rotating parts are subjected to strict static balance and dynamic balance correction, so that vibration is reduced, and noise is reduced.
