The specific embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is a kind of stereogram for preparing the large-area transparent conductive film ultrasonic spray generator special provided by the invention, referring to Fig. 1, large-area transparent conductive film ultrasonic spray generator provided by the invention includes: casing 1 and 18 ultrasonic atomizers 3 that are installed on described casing 1 bottom base panel, be positioned at described casing 1 top flanging 9 all around, be installed on the loam cake 2 on the described flanging 9, at the flanging 9 of described casing 1 and the anti-corrosive rubber pad 8 between the described loam cake 2, the carrier gas inlet 4 that on the side of described casing 1 and described loam cake 2, is provided with, spray outlet 6 and solution set on the loam cake 2 of described casing 1 enter the mouth 5, and the lower margin 7 that is positioned at four limits, described casing 1 bottom.
Need to prove that described spray outlet 6 is connected with the threaded one end of a jet pipe, and also is connected with a nozzle at the other end of described jet pipe, realize spraying at last by described nozzle.
Ultrasonic spray generator of the present invention power-on after pouring precursor aqueous solution into, thereby this solution is atomizing rapidly under the effect of the ripple of overfulfiling a production target, after gas to be atomized is full of the whole box body of this ultrasonic spray generator, open the carrier gas source of the gas, thereby the carrier gas that makes the carrier gas source of the gas be imported is being carried atomization gas from spray outlet 6 ejections.
Characteristics of the present invention are: ultrasonic spray generator of the present invention is after connecting power supply, solution of dress can atomize rapidly under action of ultrasonic waves in it, after gas to be atomized is full of whole generator casing, make carrier gas enter casing 1 respectively by opening the carrier gas source of the gas by orthogonal carrier gas inlet 4, thereby make carrier gas carry atomization gas from spray outlet 6 ejections, is connected by the jet pipe that links to each other with spray outlet 6 then and enters nozzle, thereby final the realization sprayed.
In view of present general ullrasonic spraying method is with the solution atomizing bottle of packing into; The bottle that will atomize then is placed in the ultrasonic atomizer that adds clear water, makes ultrasonic wave penetrate the purpose that the atomizing bottle reaches solution atomization.This ullrasonic spraying method atomizes to solution owing to making ultrasonic wave penetrate the atomizing bottle, so the atomizing effect of this method is undesirable, and hyperacoustic power loss is bigger.And ultrasonic spray generator of the present invention is owing to adopt the ultrasonic atomizer of corrosion resistant type, thereby the present invention need not to carry out depositing of precursor aqueous solution by the atomizing bottle, atomize in the ultrasonic spray generator casing and the ullrasonic spraying precursor aqueous solution directly can be poured into, thereby can be, and make atomization quantity increase so that the atomizing of precursor aqueous solution is very even.Because the solution atomization process of ultrasonic spray generator of the present invention is directly carried out in atomizer, therefore the atomization process inactivity loss of being carried out, thereby mean the ultrasonic spray generator provided by the invention efficient height that hazes, can be for the work of spraying continuously of large-area nozzle.Therefore in concrete practice, ultrasonic spray generator of the present invention can satisfy the demand of preparation large-area transparent conductive film.
In the concrete production practices, the casing of ultrasonic spray generator of the present invention can be set to: length is 450mm (millimeter), and width is 230mm, highly is 180mm.Ultrasonic spray generator of the present invention is provided with 18 ultrasonic atomizers at bottom half, and carrying out reverse side with self-tapping screw by base plate fixes, it is positive and do not leak solution and be as the criterion not see through the base plate of described casing 1 with screw, on the specific implementation, fixedly can to adopt thickness be the polyethylene board of 20mm to the box bottom of ultrasonic atomizer (3), the atomization quantity of each atomizer can be 300ML/H (milliliter/hour), operating frequency is 1.7MHZ (megahertz), operating current is 800MA (milliampere), and the power supply of atomizer all is connected in parallel, and is powered by the dc source of 24V.
Need to prove that on specific implementation, the dc source of the required use of ultrasonic spray generator provided by the invention can be selected the commercially available prod for use, in addition, the circuit of ultrasonic spray generator provided by the invention is simple, can make by oneself.
Introduce the concrete course of work of ultrasonic spray generator provided by the invention below:
At first, pour in the casing 1 of ultrasonic spray generator of the present invention by solution inlet port 5, screw the plug on the solution inlet port 5 then configuring a certain amount of ullrasonic spraying precursor aqueous solution;
After pouring precursor aqueous solution into and opening the ultrasonic spray generator power supply, precursor aqueous solution is realized atomizing rapidly under action of ultrasonic waves, after gas to be atomized is full of whole generator casing 1, open the carrier gas source of the gas, make carrier gas enter casing 1 respectively by two orthogonal carrier gas inlet 4 that are located at loam cake 2 and casing 1 side, carrier gas is evenly carried atomization gas by spray outlet 6 ejections then, and enters nozzle by the jet pipe connection that links to each other, thus final realization spraying.
On the specific implementation, the carrier gas that the present invention adopts can be the compressed air of drying.
Need to prove that the casing 1 of ultrasonic spray generator provided by the invention adopts the transparent polyethylene board making.Because casing 1 adopts the transparent polyethylene board making, therefore the user can observe directly the duty of each atomizing generator, and can change simultaneously the access number of concrete atomizer according to desired power neatly, thereby ultrasonic spray generator of the present invention can satisfy the needs of different atomization quantities.
Because the carrier gas of ultrasonic spray generator provided by the invention enters in the casing by two orthogonal carrier gas inlet in loam cake 2 and casing 1 side, thereby overcome the deficiency that general atomizing bottle single tube air inflow is difficult for adjusting, and make that the atomization gas that is sprayed can be more even, ultrasonic spray generator provided by the invention is more prone to the adjustment of air inflow.
In sum, because the atomization process of precursor aqueous solution need not to pass the atomizing bottle in the ultrasonic spray generator of the present invention, but the direct ultrasonic atomization that in atomizer, carries out solution, thereby can be so that the atomizing of precursor aqueous solution is very even, and make atomization quantity increase, and the atomization process inactivity that is carried out loss, thereby mean the ultrasonic spray generator provided by the invention efficient height that hazes, can be for the work of spraying continuously of large-area nozzle, thereby adopt ultrasonic spray generator provided by the invention can satisfy the demand of preparation large-area transparent conductive film, every technical indicator of the large-area transparent conductive film of preparing all reaches application requirements, can lay the first stone for industrialized large-scale production.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
