Description
Technical field
The utility model relates to Fan Equipment technical field more particularly to a kind of structures convenient for blade exchanging.
Background technique
Currently, all cast aluminum impellers of impeller used in subway, tunnel large axial flow fan, to meet different ventilations, row
Impeller blade is usually designed to adjustable angle, detachable structure by the technical requirements such as cigarette flow system flow, pressure and high temperature resistant, this
Sample blade is versatile, can meet a variety of requirements, while can also save die cost.
But the existing large axial flow fan in market more have the following problems: blower cylinder be monoblock type or welding structure,
Annulus is closed at impeller, with regard to more troublesome when needing to change after encountering some deformable blade of special circumstances or fracture, usually
It needs all to dismantle entire impeller, then replaces damaged blade, having replaced must reinstall, in this way to human and material resources, wealth
Power causes very big waste.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of knots convenient for blade exchanging
Structure can be adapted for axial fan and mixed flow fan.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of structure convenient for blade exchanging, including blower cylinder, blade, wheel hub, vane rings and motor, motor are fixed on
The blower fan cylinder body is interior and coaxial distribution, the output end of motor are connect with wheel hub between the two, is bolted on the outside of wheel hub
There is dismountable blade, is equipped with the vane rings in blade outboard on blower cylinder inboard wall, it is characterised in that: the vane rings bottom
It is equipped on end inner surface and two sides side wall in interconnected notch and notch and is equipped with the matched ring flat-plate of shape, vane rings side
Fixation hole is respectively equipped on wall on the outside of notch, the side-wall outer side of ring flat-plate is respectively equipped with backplate and at least one backplate and ring flat-plate weld
It connects, backplate is connected and fixed by bolt and the fixation hole on impeller ring-side wall.
In conclusion facilitating blade more by opening up notch the beneficial effects of the utility model are: reasonable in design
Disassembly, installation are changed, and operating process is time saving and energy saving, saves after-sales service cost.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

In figure: 1 motor, 2 wheel hubs, 3 blades, 4 blower cylinders, 5 vane rings, 6 notches, 7 ring flat-plates, 8 fixation holes, 9 bolts, 10
Backplate.
Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
It is as shown in Figures 1 to 4: a kind of structure convenient for blade exchanging, including blower cylinder 4, blade 3, wheel hub 2, impeller
Ring 5 and motor 1, motor 1 is fixed in the blower cylinder 4 and coaxial distribution between the two, the output end and wheel hub 2 of motor 1
It connects, dismountable blade 3 is fixed with by bolt 9 on the outside of wheel hub 2, is equipped on the outside of blade 3 on 4 inner wall of blower cylinder described
Vane rings 5,5 section of vane rings are the c-type structure that opening is arranged towards 4 inner wall of blower cylinder, 5 outboard end of vane rings and blower
4 inner wall of cylinder is welded and fixed；
It is equipped in interconnected notch 6 and notch 6 and is equipped on the 5 bottom end inner surface of vane rings and two sides side wall
The matched ring flat-plate 7 of shape, the opening area of notch 6 should meet blade 3 and replace required operating space, and ring flat-plate 7 is similarly opening
Towards the c-type structure of 4 inner wall of blower cylinder setting, a fixation hole 8, ring are respectively equipped in 6 two sides of notch on 5 side wall of vane rings
The side-wall outer side of plate 7 is respectively equipped with the backplate 10 welded with it, and backplate 10 passes through the fixation hole 8 on bolt 9 and 5 side wall of vane rings
It is connected and fixed, in the structure, is cooperated by ring flat-plate 7 and backplate 10 and block notch 6, will not influence in fan operation
Aerodynamic quality, in after-sales service, open bolt 9 simultaneously ring flat-plate 7 and backplate 10 are removed, pass through at notch 6 dismantle institute
State blade 3.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the protection scope of the utility model.
