Description
Technical field
The present invention relates to Fan Equipment technical field, specially Novel seismic-proof blower fan.
Background technology
At present, people often use blower fan in production and living, and blower fan mainly includes ventilation blower, compressor, air blower etc..Its
Operation principle is by rotating rotor (impeller), and steam flow is done work, and steam flow is extruded, to reach required airflow pressure.But generally
In the case of motor work can produce inevitable vibrations, because fan shaft and motor axis are not right, cause rotor and shell
Or axle is collided or worn with body seal set, service life of fan is finally reduced, another reverse side, blower fan is in different working environments
The middle easy inspiration particulate matter of air inlet so can also produce slight vibrations to wind page, destroy blower fan work, we enter to this for this
Row improves.
The content of the invention
It is an object of the invention to provide Novel seismic-proof blower fan, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：Novel seismic-proof blower fan, including base, support frame, wind
Arbor, the base top are provided with fixed block, and the fixed block is fixedly connected with dust cover, damping is provided with inside support frame as described above
Baffle plate, and damping baffle plate is close to motor both sides, the motor bottom is fixed with connecting plate, and connecting plate and base pass through damping bullet
Spring connects, and described fan shaft one end connects impeller, and the impeller is fixedly connected with blade, and blade is provided with three, the fan shaft
Provided with bearing, the bearing bottom connects bearing block.
Preferably, the fixed block is provided with U-shaped groove, and is bolted to connection with base.
Preferably, two bearings are provided with the fan shaft, and are fixedly connected with bearing block.
Preferably, the connecting plate and motor are fixedly connected by welding.
Preferably, the damping retaining device is fixedly connected in support frame both sides, and with support frame both sides by being glued.
Compared with prior art, the beneficial effects of the invention are as follows：Structure of the present invention is relatively simple, simple operation, can be effective
Against shock function is realized, avoids that motor operation vibration amplitude is larger to be impacted to blower fan, the blower fan is set on fan shaft
Two bearings are simultaneously fixed on bearing block, and motor bottom sets damping spring and damping baffle plate is fixed in side, improves blower fan work
Stability.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1-2, a kind of embodiment provided by the invention：Novel seismic-proof blower fan, including base 1, support frame 5, wind
Arbor 13, the top of base 1 are provided with fixed block 2, and fixed block 2 is fixedly connected with dust cover 8, and the inside of support frame 5 is provided with damping baffle plate
7, and damping baffle plate 7 is close to the both sides of motor 6, the bottom of motor 6 is fixed with connecting plate 4, and connecting plate 4 and base 1 pass through damping bullet
Spring 3 connects, and the one end of fan shaft 13 connection impeller 10, impeller 10 is fixedly connected with blade 9, and blade 9 is provided with three, and fan shaft 13 is set
There is bearing 12, the bottom of bearing 12 connection bearing block 11, fixed block 2 is provided with U-shaped groove, and is bolted to connection with base 1,
Two bearings 12 are provided with fan shaft 13, and are fixedly connected with bearing block 11, connecting plate 4 and motor 6 pass through the company of being welded and fixed
Connect, the device of damping baffle plate 7 is fixedly connected in the both sides of support frame 5, and with the both sides of support frame 5 by being glued.
Operation principle：This kind of assembling has dust cover 8, and is fixed on base 1 by fixed block 2, avoids larger particles
The entrance of thing, make air inlet is firm to be not easy to shake, cause to shake because fan shaft 13 deviates with electrical axis when motor 6 works
Dynamic, so setting two bearings 12 in the middle part of fan shaft 13, bearing 12 is fixed by bearing block 11, and the both sides of motor 6 are tight
Post damping baffle plate 7 and bottom is fixed with damping spring 3, maximize to reduce and shaken caused by blower fan work.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
