Abstract
The utility model relates to an ultrasonic spraying nozzle, whose metal shell and core clamp one metal foil with even minute holes and that form a chamber. The straight hole at the bottom of the chamber is connected to the spout. The straight hole at the top of the chamber is connected to the liquid supply port. The core is sleeved with piezoelectric plate and pressed tight by the pressing nut matching with metal shell screw. The atomizing grain size of the nozzle is even and will not required additional equipment to provide jetting pressure. The resonance is done by the entire nozzle. As a result, the hysteresis of control can be avoided. After the completion of spraying, the liquid will not drop or leak, because the blocking of foil plate. The atomizing grain size can be controlled via adjusting the minute hole diameter of the metal foil plate.
Description
Technical field
The ultrasonic vibration that the utility model ultrasonic spraying device utilizes the inverse piezoelectric effect principle of piezoelectric ceramics to produce, make the liquid uniform atomizing, and spraying comes out, and mainly is used in to require that sprayed surface is thin, spraying uniformly sprays in the system, especially is applied in the paint finishing of fuel cell manufacture.
Background technology
In the fuel cell development process, the PEM (PEMS) that trace, even spraying contain catalyst is its important ring.Because performances such as the spraying flow of common spraying equipment, ejection liquid particles size and uniformity coefficient are wayward, obviously can't satisfy the requirement of fuel cell paint finishing.Ultrasonic spray coating system is with its fine flow, and spraying is even, and the atomizing particle size is easy to control, and loss is few, is difficult for advantages such as obstruction, be used widely in fuel cell research and development and production process, and shower nozzle is the critical component in the ultrasonic spray coating system.Ultrasonic spray shower nozzle in the market is mainly from the Taiwan or external import, price is very high, technology also is blocked, and a tangible drawback is arranged in the external similar products, have the poly-phenomenon of liquid water clock or liquid exactly after stopping spraying suddenly, the uniformity when this can give next the spraying produces very big obstacle.
In order to reduce the price of paint finishing, break blockade on new techniques, for domestic how tame colleges and universities provide paint finishing efficiently to the research and development and the production of fuel cell.The utility model device provides a kind of ultrasonic spray coating system shower nozzle, and this shower nozzle not only can spray the vaporific liquid of diameter 7-10 μ m, and spraying evenly, and noiseless need not to add gas pressure and helps spray.
The utility model content
The purpose of this utility model is at the problem that exists in the prior art, and a kind of ultrasonic spray shower nozzle is provided, and this shower nozzle not only can spray the vaporific liquid of diameter 7～10 μ m, and spraying evenly, and noiseless need not to add gas pressure and helps spray, simple in structure, cost is low.
In order to achieve the above object, design of the present utility model is: the ultrasonic vibration of utilizing the inverse piezoelectric effect principle of piezoelectric ceramics to produce excites the intrinsic vibration of this shower nozzle, drive the metal forming vibration that contains thousands of 7-10 μ m micro-holes with this, cause the upper end of metal forming when liquid, because the ultrasonic wave dither of tinsel has been broken the tension force of liquid surface, liquid will produce several microns sizes and have the atomizing particle of certain speed by micro-hole, thereby to reach the effect that the atomization of liquid is sprayed, this novel spraying shower nozzle adopts special material, anti-strong acid.
According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of ultrasonic spray shower nozzle comprises a metal shell, it is characterized in that having a core body, and pressing clip is joined a tinsel that fine aperture is arranged between the inner bottom surface of its inner face and metal shell, and forms chamber at the upper and lower sides of tinsel middle section; The lower chamber of this chamber is by the spout of straight hole connection metal shell lower end, and its upper chamber connects the supply opening of core body upper end by straight hole; Described core body suit piezoelectric patches, and the bottom surface of piezoelectric patches is supported on the flange surface of core body bottom, compresses and the last end face of piezoelectric patches revolves the clamp nut of joining by one with the metal shell screw thread; There is the lead that connects piezoelectric patches to draw from the hole on the clamp nut.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: in the utility model, suit piezoelectric patches on the core body, produce ultrasonic vibration and excite the intrinsic vibration of shower nozzle, and drive tinsel and do dither, the dither of tinsel is broken the surface tension of liquid, produce tiny atomization of liquid particle by top micro-hole, the liquid particle diameter of atomizing can reach 7～10 μ m, and atomizing particle size is even, need not ancillary equipment jet atomization pressure is provided; Because whole shower nozzle is all in little resonance, so the no hysteresis of control; After spraying finishes and since tinsel stop with the spout place this in the vibration that does not stop, oozing and weeping can not appear in fluid.The utility model is simple in structure, compact, reasonable, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1, the spray of this ultrasonic spray includes a cylindrical metal shell 8 greatly, a core body 9 is arranged, pressing clip is joined a tinsel 6 that fine aperture is arranged between the inner bottom surface of its inner face and metal shell 8, and forms chamber 5 at the upper and lower sides of tinsel 6 middle sections; The lower chamber of this chamber 5 is by the spout 7 of straight hole connection metal shell 8 lower ends, and its upper chamber connects the supply opening 1 of core body 9 upper ends by straight hole; Described core body 9 suits two piezoelectric patches 4, and the bottom surface of piezoelectric patches 4 is supported on the flange surface of core body 9 bottoms, compress and the last end face of piezoelectric patches 4 revolves the clamp nut 3 of joining by one with metal shell 8 screw threads; Having to connect presses two leads 2 of two piezoelectric patches 4 to draw from the hole on the clamp nut 3.
Above-mentioned metal shell 8, core body 9, tinsel 6 and clamp nut 10 all adopt the material of anti-strong acid, and then this shower nozzle is applicable to the paint finishing of producing fuel cell.
