Description
Technical field
The utility model patent is related to a kind of energy-efficient dust absorption fan, and it is centrifugal fan structure, scroll casing type
Fan casing, using semi open model major diameter impeller, mechanical seal at rotating shaft, novel efficient two level motor.Rotating speed is fast, air draught power
Greatly, noise is small, power saving, simple in construction, and installation is very convenient, can be widely used in production and life.
Background technology
Currently used dust absorption fan is unreasonable due to structure, small air draught power, noise and vibration usually occurs greatly, power consumption
The shortcomings of more.It is unreasonable structure that the reason for causing above mentioned problem, which has the reason for many, thumping majority, the fan blade accuracy of manufacture
Low or insufficient strength, as a result occur as soon as problem under the running at high speed of motor.
The content of the invention
The utility model patent is related to a kind of energy-efficient dust absorption fan, it mainly by：Fan casing (1), impeller (2), inhale
Entrance (3), impeller locking nut (4), stopping shim (5), mechanical seal (6), two level motor (7), electric machine support (8) composition.
The Fan casing (1) of scroll casing type is made in 3mm steel plates from thickness, in order to reduce the volumetric loss of blower fan, therefore Fan casing and leaf
The gap designed between wheel is 10mm, and housing centre side is blower fan suction inlet (3), and opposite side is machine shaft entrance, is inhaled
For entrance into horn-like, openning is small.Impeller (2) uses semi open model major diameter impeller, and overall cast with aluminium material forms, whole impeller
It is made up of blade fixed plate (9), primary blades (10), auxiliary blade (11).Impeller fixed plate is that one piece of thickness is 6mm large-diameter circulars
Plate, is onboard uniformly distributed primary blades (10) and auxiliary blade (11) is integrally formed, and is opened in the circle centre position close to blade fixed plate (9)
There is the machine shaft hole of a fixed impeller, be fixed on impeller with one piece of stopping shim (5) and an impeller locking nut (4)
On machine shaft.It is the air inlet of impeller in the circle centre position of major diameter plectane, in order to reduce flow losses, improves flow efficiency,
Design primary blades (10) are being stretched close to center of circle air inlet using the gradual edge to the periphery of involute in form, whole primary blades (10)
Width is gradually increased from air inlet to air outlet, uniform one piece of auxiliary blade (11) between two primary blades.For anti-leak-stopping
Wind, friction loss is reduced, gap uses mechanical seal between Fan casing and machine shaft, and motor selects novel efficient two level
Motor, on the basis of motor machine support (8) is fixed on.
This patent beneficial effect is to operate steadily, efficient energy-saving, and blast is high, suction foot, preferably can meet to produce and live
Need.

Embodiment
In order to improve blower fan flow efficiency, flow losses and friction loss are reduced, accomplishes efficient, energy-conservation, low noise, so first
Optimization design is first carried out from blower fan structure, the Fan casing (1) of scroll casing type is made in 3mm steel plates from thickness, in order to reduce wind
The volumetric loss of machine, therefore the gap designed between Fan casing and impeller is 10mm, housing centre side is blower fan suction inlet
(3), opposite side is machine shaft entrance, and for suction inlet into horn-like, openning is small.Blade shape, size are rationally designed, fluid is existed
The change of runner medium velocity is steady, avoids dead angle and produces vortex, impeller (2) uses semi open model major diameter impeller, integrally uses aluminium
Material casting is formed, and whole impeller is made up of blade fixed plate (9), primary blades (10), auxiliary blade (11).Impeller fixed plate is one piece
Thickness is 6mm major diameter plectanes, is onboard uniformly distributed primary blades (10) and auxiliary blade (11) is integrally formed, and is consolidated close to blade
The circle centre position of fixed board (9) is provided with the machine shaft hole of a fixed impeller, with one piece of stopping shim (5) and an impeller locking screw
Impeller is fixed on machine shaft by female (4).It is the air inlet of impeller in the circle centre position of major diameter plectane, design primary blades (10)
Close to center of circle air inlet, using involute in form, gradually edge is stretched to the periphery, the width of whole primary blades (10) is from air inlet
Gradually increase to air outlet, uniform one piece of auxiliary blade (11) between two primary blades.In order to prevent leaking out, friction damage is reduced
Lose, gap uses mechanical seal between Fan casing and machine shaft, and motor selects novel efficient two level motor, motor
On the basis of machine support (8) is fixed on.
