Description
Technical field
The present invention relates to a kind of sound insulation wall type axial-flow fans, belong to field of mechanical technique.
Background technique
Axial fan, which is gained the name, flows into impeller and along axial outflow from axial in fluid.Its working principle is managed based on winged petiole type
By: gas from air inlet axially into impeller when, generate a lift in wing back, while a size phase is generated on wing abdomen
Etc. contrary active force, which move gas discharge impeller twist axially forward.Meanwhile at fan inlet by
In the effect of pressure difference, gas is constantly inhaled into.
Currently, axial fan is widely used in a variety of occasions for needing to divulge information, especially certain industrial occasions, it is special to enter
Smelting, chemical industry, electric energy etc., although main application scenarios all have been realized in automation, the axial fan of low noise
It is still to need at present.
Range accounts for the 60% to 80% of whole system impedances between air intake vent and air outlet, and in addition air-flow is bigger, and noise is opposite
Higher.System impedance is higher, and air-flow is bigger, therefore in order to minimize noise, and system impedance must reduce to minimum level.
It is therefore necessary to design a kind of sound insulation wall type axial-flow fan, to solve the above technical problems.
Summary of the invention
In view of the above-mentioned deficiencies, the present invention provides a kind of sound insulation wall type axial-flow fans.The present invention is by following technology
What scheme was realized:
A kind of sound insulation wall type axial-flow fan, including, the first installation position, the first fan, the second installation position, the second fan, third peace
Fill position, third fan, the first block piece, the second block piece, motor, filler material, blower housing, transmission system, the blower
Shell is equipped with the first installation position, the second installation position, third installation position, sets respectively on first, second, third installation position
There is the first, second, third fan, be respectively equipped with first, second on the inside edge of first, second, third installation position,
Third block piece, the blower housing inside are filled with filler material, are additionally provided with transmission system inside the blower housing, institute
The first, second, third installation position stated is circle, and the diameter of first, second, third installation position is sequentially reduced, institute
The blade diameter for the first, second, third fan stated is sequentially reduced, and first fan can be changed to turbofan, and second
It is commonly to dissipate blade fan with third fan；It is equipped with multiple connecting columns inside the blower housing, is used to fixing shell；The connection
Column is elastic steel construction, and the blower housing is double-layer structure.
The present invention reduces the straight of each fan by the improvement to original wall type aerofoil fan progress disintegration
Diameter reduces large area fan sound and crosses wind because of noise problem caused by blade vibration while ensure that wind area.
Preferably, first, second, third fan is made of the circle wheel of periphery and internal blade, described
Circle wheel can lace.
Preferably, multiple connecting columns are equipped with inside the blower housing, are used to fixing shell.
Preferably, the tapered ring-type of the block piece.Block piece ensure that air-flow generation when entering is blocked part and draws
The case where leading, large area gas current friction installation position edge avoided to generate vibration as far as possible.
Preferably, the transmission system further includes belt, described first and second, third fan circle wheel pass sequentially through
Belt is connected, and the motor is mounted in the shaft of the first fan, during transmission, because efficiency is declining always,
Therefore, the fan of different-diameter is driven by the belt pulley of different order.
Preferably, the motor connects transmission system, and the motor is filled material and surrounds.Due to the limit of motor itself
System, motor itself can also generate vibration, and therefore, selection surrounds motor using filler material, effectively absorb the vibration of motor,
Reduce the noise of motor itself.
Preferably, the support column of the interior of shell is equipped with spring.The upper spring of support column, also plays and subtracts
The effect of the shake spring is changed to elastic.
Compared with traditional axial fan, the application changes the form of conventional fan, reduces wind to a certain extent
The vibration of machine optimizes blower configured in one piece using multiple settings for crossing wind face, and is provided with and subtracts in the enclosure interior of blower
Buffer unit is shaken, reduces the possibility for generating overall resonance, and increase a variety of mechanisms that can choose, so that design more adds
It is whole.
Detailed description of the invention
Fig. 1 is overall construction drawing of the present invention,
Fig. 2 is front view of the invention,
Fig. 3 is filler material structure chart of the invention；
In figure, the 1, first installation position, the 2, first fan, the 3, second installation position, the 4, second fan, 5, third installation position, 6, third
Fan, the 7, first block piece, the 8, second block piece, 9, third block piece, 10, filler material, 11, connecting column, 12, blower housing.
Specific embodiment
A kind of sound insulation wall type axial-flow fan, including, the first installation position 1, the first fan 2, the second installation position 3, the second fan
4, third installation position 5, third fan 6, the first block piece 7, the second block piece 8, motor, filler material 10, blower housing, power train
System, the blower housing are equipped with the first installation position 1, the second installation position 3, third installation position 5, and described first, second, the
It is respectively equipped with the first, second, third fan on three installation positions, divides on the inside edge of first, second, third installation position
Not She You the first, second, third block piece, filler material 10, the blower housing are filled with inside the blower housing 12
Transmission system is additionally provided with inside 12, first, second, third installation position is circle, and described first, second, third
The diameter of installation position is sequentially reduced, and the blade diameter of first, second, third fan is sequentially reduced.The present invention by pair
Original wall type aerofoil fan carries out the improvement of disintegration, reduces the diameter of each fan, ensure that wind area
Meanwhile reducing large area fan sound and crossing wind because of noise problem caused by blade vibration.
First, second, third fan is made of the circle wheel of periphery and internal blade, and the circle wheel can connect
Belt, while the first fan can be changed to turbofan, second and third fan are commonly to dissipate blade fan；Such turbofan
