Abstract
The present invention relates to a draught fan driven by wind, which comprisesan air drafting cylinder whose upper direction can be provided with a component composed of an upper impeller and a lower impeller in a rotary way. When the natural wind blows towards the upper impeller and the lower impeller in the direction perpendicular to the shaft of the impeller component, vanes of the windward faces of the upper impeller and the lower impeller can drive the impeller component to rotate under the action of wind force. Vanes of the lee faces of the rotary upper impeller and the lower impeller can generate the centrifugal action to the air, the impellers being thrown out. Thus, low pressure is formed near the vertical shaft of each impeller and the air in the air drafting cylinder can generate the air drafting action. The present invention can work normally under the condition of the secondary natural wind.
Description
The present invention relates to a kind of by wind-driven naturally induced draught fan.
EP0045615A1 discloses a kind of induced draught fan of being used by air operated Motor Vehicle that is flowing and building.This induced draught fan has a centrifugal cutter and one by the air operated rotor that is flowing.This rotor has a base plate that is used for making the air diverts by centrifugal cutter and one from the outward extending inlet, outlet of this base plate.This inlet, outlet is made up of two arc shaped blades.These two arc shaped blades hide mutually at their concave surface place and separate each other, so that form a sinusoidal air passageways between these two blades.The shortcoming of this induced draught fan is, the space between said rotor and the centrifugal cutter is separated by base plate, thereby rotor only plays motor, and centrifugal cutter only plays induced draught fan, can not make full use of wind energy like this, has influenced the effect of air inducing again.
Task of the present invention provides a kind of its upper and lower impeller can play wind motor, plays the draught fan by wind force of centrifugal air inducing effect simultaneously again.
Draught fan by wind force of the present invention has a wind guiding tube, two bearing bracket of fixed installation on this wind guiding tube, two bearings are installed in respectively on two bearing bracket, these two bearings have identical shaft axis with described wind guiding tube, a rotating axle is installed between two bearings, there is one by last, the parts that following impeller sets becomes, last impeller is by the upper circular supporting plate, intermediate membrane and the blade that is fixedly mounted between them are formed, following impeller is by bottom ring support plate, described intermediate membrane and the blade that is fixedly mounted between them are formed, on described, following wheel member is fixedlyed connected with described rotatingshaft with the radial support bar on being fixedly connected on described bottom ring supporting plate by described upper circular supporting plate, it is characterized in that, described intermediate membrane is ring, there is a through hole at the center, described on, each interlobate space of following impeller is interconnected by this through hole.
Task of the present invention also can solve like this.Induced draught fan of the present invention has a wind guiding tube, support of fixed installation on this wind guiding tube, an axle is fixedly mounted on this support, a bearing respectively is equipped with at the two ends of axle, a sleeve is housed between the outer ring of these two bearings, this has common shaft axis with this sleeve, there is one by last, the parts that following impeller sets becomes, last impeller is by the upper circular supporting plate, intermediate membrane and the blade that is fixedly mounted between them are formed, following impeller is by bottom ring support plate, described intermediate membrane and the blade that is fixedly mounted between them are formed, on described, following wheel member is fixedlyed connected with described sleeve with the radial support bar on being fixedly connected on described bottom ring support plate by described upper circular cover plate, on being somebody's turn to do, following wheel member and this sleeve can rotate on this axle together, its characteristics are, described intermediate membrane is ring, there is a through hole at the center, described on, each interlobate space of following impeller logical also is interconnected by this.
Draught fan by wind force of the present invention is work like this.When natural wind when a direction vertical with the axle that the draught fan impeller parts are installed blows to the upper and lower impeller of blower fan, the blade of the windward side of upper and lower impeller is subjected to the effect of wind-force, produced moment of rotation, make the wheel member rotation, the blade of the lee face of the upper and lower impeller that is rotating then produces centrifugal action to air, it is dished out in wheel member, so just near the longitudinal axis center of wheel member, cause low pressure, produce the effect of suction air inducing.The blade of the upper and lower impeller of draught fan by wind force of the present invention is to be exposed to fully in the atmosphere, so natural wind all has effect to them, moment all rotates, again because of near the space the longitudinal axis center of the upper and lower impeller of draught fan by wind force of the present invention all is communicated with wind guiding tube, so they all produce pumping action to the air in the wind guiding tube.The upper and lower impeller of induced draught fan of the present invention all plays wind motor and centrifugal air inducing simultaneously.
Below in conjunction with the represented embodiment of accompanying drawing, describe the present invention.
