Preferably, the left side surface and the right side surface are both curved in the clockwise direction.

Preferably, the circle cutting angle of the bottom ends of the left side surface and the right side surface is 45 degrees.

Advantageous effects

The utility model discloses a nimble general through-flow vortex shaft fan of energy saving and emission reduction, this fan structure is traditional fan structure more, the advantage lies in three-dimensional induced air, it promotes 100% to compare traditional mode induced air effect, the fixed point of axial compressor mode is aired exhaust, it removes dust to compare the tradition to air exhaust, wind-force is concentrated, the noise is low, even, the low diffusion, it is long to air exhaust the distance, vortex dust collection efficiency is higher, reducible rearmounted relevant collection auxiliary device, total effective rate is synthesized and is promoted more than 50%, reduce relevant equipment volume more than 50%, reduce the use amount of relevant equipment material, reach energy saving and emission reduction's purpose.

Use behind the fan, air conditioner cooling system can change the annular heat transfer into, the middle this fan that uses can reduce heat transfer structure's material quantity, reduce the volume of the outer machine of heat dissipation more than 30%, match the warm area of heat exchanger completely, the heat dissipation is more even, the running noise is low. Industry collection wind dust collecting system is also so, can be according to the source of on-the-spot raise dust, extends fan structure length, and induced air efficiency is higher, and ordinary fan exists the drawback such as collection wind system drainage distance is short, the noise is big, this patent the induced air piece face nature of more ordinary fan of fan, more have the advantage of three-dimensional induced air, be applicable to the three-dimensional induced air collection dirt in space more.

Detailed Description

Hereinafter, the present invention will be described in detail. Before the description is made, it should be understood that the terms used in the present specification and the appended claims should not be construed as limited to general and dictionary meanings, but interpreted based on the meanings and concepts corresponding to technical aspects of the present invention on the basis of the principle that the inventor is allowed to define terms appropriately for the best explanation. Accordingly, the description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the invention, so it should be understood that other equivalents and modifications could be made thereto without departing from the spirit and scope of the invention.

The following examples are given by way of illustration of embodiments of the invention and are not intended to limit the invention, and those skilled in the art will appreciate that modifications within the scope of the invention do not depart from the spirit and scope of the invention.

Example 1

As shown in figure 1, a nimble general through-flow turboshaft fan of energy saving and emission reduction, including bobbin 1, the bobbin both ends are provided with first end cover 2, second end cover 3 respectively, the center department of bobbin is equipped with axis of rotation 7, and a plurality of flabellum 4 are followed the axis at bobbin place is the circumference and evenly arranges, as shown in figure 2, the flabellum includes left surface 5 and right flank 6, left surface and right flank all incline the setting forward along the clockwise, the left surface inclines 20 settings forward along between clockwise and the bobbin, the right flank inclines 40 settings forward along between clockwise and the bobbin.
