Abstract

The utility model discloses a fan impeller, which comprises an upper fixed disk, a lower fixed disk and a plurality of twisted blades, wherein the circumferential surfaces of the upper fixed disk and the lower fixed disk are provided with a plurality of semicircular slots; the upper fixed disk and the lower fixed disk are connected into a disk-shaped wheel hub of which the circumferential surface is provided with a plurality of installing grooves through fastening screws; revolving shaft holes are formed in the centers of the upper fixed disk and the lower fixed disk; the roots of the twisted blades are provided with cylindrical reinforced ribs; the cylindrical reinforced ribs are fixed in the installing grooves formed by the upper fixed disk and the lower fixed disk. In the fan blade, the twisted blades are adopted, thereby effectively reducing the air resistance of the impeller in a running process, reducing the fluid losses and enhancing the strength of the blades. The wheel hub consist of the upper fixed disk and the lower fixed disk, fastening pieces are fixed inside an internal space formed by the upper fixed disk and the lower fixed disk, and meanwhile the upper fixed disk is provided with an arc-shaped flow guide top cover, thereby effectively preventing the phenomenon of eddy current in the running process. The fan impeller has the advantages of high efficiency, long service life and attractive and elegant appearance.

Description

Draught fan impeller
Technical field
The utility model relates to blower fan accessory technical field, is specifically related to a kind of draught fan impeller.
Background technique
Blower fan is that the custom of gas compression and gas conveying machinery is called for short, and usually said blower fan comprises ventilator, blower, wind-driven generator.Gas compression and gas conveying machinery are that the mechanical energy of rotation is converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.Blower fan main structural components is impeller, casing, intake grill, support, motor, belt pulley, coupling, baffler, driving component (bearing) etc.The impeller of blower fan is mainly comprised of wheel hub and some blades at present, blade is mostly rectangular configuration, surfacing, in this blade running, windage is larger, flow losses are large, especially for longer blade, windage in running can cause damage to the intensity of blade own, in the working life that shortens impeller, the wheel hub of this out rotor is all monolithic construction, outside the fastening piece between wheel hub and blade is directly exposed to, affected the aesthetics of impeller, wheel hub, in blade center, easily produces vortex phenomenon in running, affects the overall operation of blower fan.
Model utility content
The utility model provides a kind of draught fan impeller, and to solve, the fan operation windage that prior art exists is large, wheel hub causes eddy current and inaesthetic problem.
The utility model device solves the technological scheme that its technical problem adopts:
A kind of draught fan impeller, comprise fixed tray, lower fixed disk and several twisted blades, the circumferential surface of upper fixed tray and the circumferential surface of lower fixed disk arrange some semicircle hole slots, upper fixed tray and lower fixed disk connect into by fastening screw the discoid wheel hub that circumferential surface has some mounting grooves, the central position of upper fixed tray and lower fixed disk is provided with rotary shaft hole, twisted blade root arranges cylindrical stiffening rib, cylindrical stiffening rib is fixed in the mounting groove that fixed tray and lower fixed disk form, and the top of upper fixed tray arranges and is used for the arc overhead guard of water conservancy diversion.
Twisted blade of the present utility model, upper fixed tray and lower fixed disk adopt SMC material to make.
Blade of the present utility model adopts twisted blade, has effectively reduced the windage in impeller running, has reduced flow losses, has also improved the intensity of blade simultaneously; Wheel hub is comprised of upper fixed tray and lower fixed disk, adopt split-type structural, fastening piece is all installed in the inner space of fixed tray and lower fixed disk formation, go up the arc overhead guard that fixed tray arranges water conservancy diversion simultaneously, effectively prevented vortex phenomenon in running, had advantages of that efficiency is high, long service life and elegant in appearance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic top plan view of the present utility model;
Fig. 3 is front elevational schematic of the present utility model;
Fig. 4 is the structural representation of the utility model twisted blade;
Fig. 5 is the installment state schematic diagram of fixed tray and lower fixed disk on the utility model.
Fixed tray, 2 lower fixed disks, 3 twisted blades, 4 arc overhead guards, 5 rotary shaft holes, 6 fastening screws, 7 semicircle hole slots, 8 mounting grooves, 31 cylindrical stiffening ribs on 1 in figure.
Embodiment
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of draught fan impeller, comprise fixed tray 1, lower fixed disk 2 and several twisted blades 3, the circumferential surface of the circumferential surface of upper fixed tray 1 and lower fixed disk 2 arranges some semicircle hole slots 7, upper fixed tray 1 and lower fixed disk 2 connect into by fastening screw 6 the discoid wheel hub that circumferential surface has some mounting grooves 8, the central position of upper fixed tray 1 and lower fixed disk 2 is provided with rotary shaft hole 5, twisted blade 3 roots arrange cylindrical stiffening rib 31, cylindrical stiffening rib 31 is fixed in the mounting groove 8 of fixed tray 1 and lower fixed disk 2 formation, the top of upper fixed tray 2 arranges and is used for the arc overhead guard 4 of water conservancy diversion.
