Description

Spraying axial-flow fan

Technical field

The utility model belongs to textile air-conditioner facility technology field, is specifically related to a kind of spraying axial-flow fan, is used for the humidity of carrying fresh air and regulating the air of spinning and weaving workshop simultaneously to spinning and weaving workshop.

Background technology

China utility model patent Granted publication CN2085044Y and CN2622435Y all disclose the spraying axial-flow fan with humidification function, the latter lays particular emphasis on the improvement to the structure of blade, and the former technical essential is to set up mechanical atomizer and set up confession, water gall mechanism in the wheel hub of impeller in housing, and on main cylinder adjunction atomizing diffuser, thereby air-supply and humidification are carried out synchronously.The spraying axial-flow fan of this structure is by shown in Figure 4: comprise main cylinder 1, be positioned at air inlet one side and (butt joint) wind collection body 2 that be connected with main cylinder 1 of main cylinder 1, be located at the motor 3 in the wind collection body 2, impeller 4, feed pipe 5 and atomizer 6, wind collection body 2 is taken main cylinder 1 and is installed on the underframe 21, motor 3 is installed in the wind collection body 2 by electric machine support 31, impeller 4 is fixed by its wheel hub 41 and the motor shaft that is stretched over the motor 3 in the main cylinder 1, atomizer 6 is located in the wheel hub 41, one end of feed pipe 5 is connected with water supply line, the other end extend into atomizer 6 in, external conical sleeve 61, between 62.Concrete operation principle can see the specification of CN2085044Y for details.

The air-supply humidification of the spraying axial-flow fan of said structure embodies like this, feed pipe 5 directly will be concentrated by the water that water supply line such as tap water pipe line are introduced and supply with atomizer 6, promptly enter in the inner conical drogue 61 of atomizer 6, and then the impeller disc of arrival impeller 4, inlet opening on the impeller disc 42 arrives the rear side of impeller disc again, owing to leave the gap between impeller disc and the water retaining disk 43, make water in this gap, form a runner, produce a kind of centrifugal force this moment under the high speed rotation of impeller 4, under action of centrifugal force, shed to the circumferencial direction of impeller 4 by the water that water retaining disk 43 keeps off back, atomizer 6 is made water fogging, water smoke after the atomizing is again through the cutting of impeller 4 and strike and form the water smoke curtain, in this process, some water droplet collides mutually and forms bigger water droplet, and these bigger water droplets are thrown to the sluicing groove 7 that is located at main cylinder 1 by the blade tip of impeller 4, comes together in the sluicing cylindrical shell 71 of sluicing groove 7 and by the drainage interface 711 that continues on sluicing cylindrical shell 71 to discharge; The water smoke curtain that is formed by the effect of impeller 4 mixes mutually with the air that is imported by wind collection body 2 and produces supersaturated air, and supersaturated air then sprays from the air outlet of main cylinder 1, thereby finishes whole air-supply and humidification.

The spraying axial-flow fan of said structure is through facts have proved the shortcoming of two places below the existence: the one, and the structure more complicated, not only atomizer 6 to be installed in wheel hub 41, but also need process (circle) sluicing groove 7 together at 1 position of main cylinder corresponding to the blade tip of impeller 4, on sluicing groove 7, set a sluicing cylindrical shell 71, therefore cause the difficulty of processing main cylinder 1 to increase, the workload of processing and installing atomizer 6 in addition is bigger equally; The 2nd, atomizing effect is poor, and water waste is big, is not enough to embody energy-conservation, and this is because atomizer 6 is difficult to digest the water of being supplied with by feed pipe 5, promptly is difficult to and will be fully atomized by the water that feed pipe 5 is supplied with.Therefore be necessary the spraying axial-flow fan of this structure is improved, technical scheme described below is based on producing under this prerequisite.

Summary of the invention
