Abstract
The utility model relates to a fan exchanger, it mainly include with the radial fan leaf of being connected of center pin and with the arc blade that center pin syntropy, circumference distribute to and be used for joint support's auxiliary member, like movable ring circle, fixed ring circle, annular pedestal seat etc.. The ventilation device is generally installed on the roof of a large-scale factory building, and mainly uses natural wind as power to discharge smoke dust and gas harmful to human bodies in the factory building so as to achieve the effect of ventilation. It has the advantages of reliable strength, high ventilation efficiency and long service life.
Description
Technical field: the utility model relates to a kind of ventilation equipment.
Background technology: existing roofing ventilation equipment, be to lean on its arc shaped blade of locating without under the effect of natural wind, to rotate, produce a draught head, make air outflow within doors, drive flabellum rotation in the blower fan mouth simultaneously, auxiliary air draft, process as can be known thus, fan has really become parts that play a secondary role in this process, because be the power that effluxes of air within doors, be derived from the draught head that room outer arcuate blade rotation produces, and fan passive rotation not only in the blower fan mouth also to stop the outflow of air within doors.In addition, this ventilating fan structurally also shows certain deficiency, form a circular outer cover as numerous arc shaped blades and movable ring, loam cake, only link to each other with loam cake by a bearing by central shaft, relative intensity is lower, and central shaft, bearing two sides all expose, and very easily makes its lubricant effect invade variation because of dust, finally can't rotate because of resistance increases.
Summary of the invention: little in order to overcome existing ventilation equipment ventilation, shortcoming such as structural strength low and service life is short, suitable architecture advances has newly been done in this practicality.
The utility model is mainly by the following technical solutions: fan leaf inner end is connected in sleeve pipe, and the outer end is connected in movable ring; Be equipped with a sleeve pipe in the central shaft outside, sleeve pipe is equipped with upper bearing (metal), lower bearing in the two ends up and down; Sleeve pipe upper end is fixed on center below the loam cake, and the lower end crosses bearing and the central shaft end is fixed on the pedestal.
By above technical scheme as can be known, the kinetic energy that the power of fan rotates together with sleeve pipe from numerous arc shaped blades, it is the active exhaust ventilation form of the mutual delivery type of a kind of kinetic energy, ventilation efficiency significantly improves, be connected to multiple spot between numerous arc shaped blades and link to each other with sleeve pipe, structural strength improves.
Description of drawings:, accompanying drawing is made schematic illustration below in conjunction with an embodiment.Fig. 1 is the perspective view that the utility model is removed the front portion arc shaped blade; Fig. 2 is the axial cutaway view sketch map of the utility model.
The specific embodiment: as shown in Figure 1 and Figure 2, be a novel embodiment of this reality, numerous arc shaped blades 50 upper ends link to each other with a circular upper cover 52 among the figure, a lower end and movable ring uniform linking to each other of 51 upper edges, each arc shaped blade 50 all has an axial torsion, formation is that the both sides of symmetry axis have different stress surfaces with central shaft 30, can rotate under the wind-force effect.Match in the upper end of a bearing 53 concentricity axles 30 in inboard, loam cake 52 center, central shaft 30 lower ends also have another bearing 31, in the outside of two bearings and central shaft 30, and sleeve pipe 20 that is complementary with central shaft 30 length of suit.Sleeve pipe 20 overlaps central shaft 30 therein, and two bearings 53,31 is in the two ends of sleeve pipe 20.Can prevent the dust intrusion, less wearing and tearing are arranged when guaranteeing to rotate, between movable ring 51 inner ring surfaces and sleeve pipe 20,4 fan leaves are arranged again, 4 fan leaves connect together ring 51 and sleeve pipe 20, another effect is to play the effect of reinforced structure, and fixedly ring 40 external diameters are less than the internal diameter of movable ring 51, and both are nestable shape, leave suitable gap, wherein have three pedestals 41 fixedly the concentricity axle of ring 40 fix and be connected together.
