Description
Technical field
The invention belongs to industrial cleaning technique field, be specifically related to a kind of processor for ultrasonic wave with mixed wavelengths.
Background technology
In the ultrasonic cleaning and other application of every field, generally use ultrasonic wave to carry out cleaning operation, it mainly is to rely on ultrasonic cavitation that concrete ultrasonic wave cleans principle, promptly form countless bubbles and implosion rapidly in cleaning fluid fast, the workpiece surfaces externally and internally dirt that the impact that implosion produces will be immersed in the cleaning fluid peels off.In the ultrasonic cleaning of every field and other are used, generally adopt the single-frequency ultrasonic unit, the frequency that conventional ultrasonic cleaning apparatus uses is generally in 20KHz～120KHz scope, and an equipment can only be a Frequency point job.
Because the material of various materials is not quite similar, the dirt degree difference that material surface adheres to, especially when there is small space in material, the wavelength that low frequency long wave ultrasonic processor is sent is longer, and ultrasonic reflections is got back in the liquid when running into the space, can't enter inside, space, can not well clean the dirt of inside, space, exist the cleaning dirt not thorough, the problem that residue is many, cleaning efficiency is low.Same, in the less situation of the filter opening of filtering material, excessive ultrasonic wavelength can be reflected when running into the filter material space, thereby can't penetrate into the filter material space, makes to be more difficult to get cleaning in the filter opening.
When in emulsion, handling, ultrasonic energy is radiated in the emulsion, makes it to produce a series of ultrasonic effects, as stir, coalescent, cavitation, warm, negative pressure etc., thereby reach the destruction oil-water interfacial film, play the effect of breakdown of emulsion.Because ultrasonic wave all has conductibility preferably in You Heshui, so the ultrasonic dehydration method is applicable to various types of emulsion.But ultrasonic wave commonly used is at present handled frequency, and the wavelength ratio emulsion droplet of generation is big, and ultrasonic wave can't penetrate emulsion droplet; And ultrasonic wave also can play emulsification in breakdown of emulsion, and big water droplet and the larger oil droplet assembled are broken up again, form more tiny particle, make emulsion more stable, strengthened the difficulty of breakdown of emulsion on the contrary, so can't arrive breakdown of emulsion well, extract the purpose of emulsion droplet component content.Such as, in the cow's milk product detected, when contained Tetracyclines residual component detected, the extraction of milk sample was handled very loaded down with trivial details time-consuming, cumbersome.
In the extraction of Chinese medicine is extracted, utilize ultrasonic dispersion to destroy plant tissue, the effect of accelerated solvent penetrate tissue improves the Chinese herbal medicine effective ingredients recovery rate, but the stripping of effective medicinal component need pass several even the dozens of cell membrane just can enter in the solvent, then just can be absorbed by the body.And the ultrasound assisted extraction technique that adopts at present, long wavelength can't penetrate the fiber and the cell of medicinal material, thereby can't extract the active ingredient of Chinese medicine well, wherein, quite a few cell composition can not pass cell membrane and enter solvent, and this part can only be thrown away in vain.Extract fully as reaching, need to prolong extraction time, increase extraction time, this has influenced extraction efficiency again greatly.
Electron trade is that ultrasonic wave cleans application the earliest, the most the industry of Pu Jiing.But ultrasonic cleaner commonly used at present, it is ultrasonic that the supersonic frequency that adopts mostly is the low frequency long wave greatly, the frequency of using is generally in 20KHz～120KHz scope, ultrasonic power is bigger, exist when the electronic component of precision is cleaned fine gap cleaning dirty, circuit board, solder joint are had problems such as damage.
Clean relatively with general 20～120KHz low frequency ultrasound, million frequency ultrasonic cleaning technique have following characteristics:
(1) avoided being cleaned the object surfaces damage, megasonic can not produce strong cavitation effect, can avoid the surface damage that may occur in the cleaning process like this,, then not have damage problem with million frequency ultrasonic cleaning for the accurate device of some easy damaged in low-frequency ultrasonic waves cleans;
(2) can remove particle attached to the sub-micron on surface, million ultrasonic cleaning frequently are except strengthening the Chemical cleaning effect, more prior is that it can remove the from the teeth outwards little molecule to 0.15 μ m of absorption expeditiously, this be general low frequency ultrasound clean and other methods unapproachable;
(3) high directivity of Qing Xiing in low frequency ultrasound cleans, is cleaned the part that object immerses cleansing medium and can both obtains cleaning, one side and in million ultrasonic cleaning frequently, immerse part only towards just being cleaned that transducer, supersonic beam directly are radiated;
(4) high frequency has reduced viscous boundary layer (pool exert in effect), make ultrasonic wave can ' discovery ' superfine little particulate.
But high frequency ultrasound in use because cavitation intensity is low, makes cleaning strength low excessively, has the incomplete problem of cleaning.Simultaneously, because million frequently ultrasonic directionality make not parallel with million frequency acoustic beams part can not get cleaning.
Below, conventional ultrasound is cleaned the situation of cleaning with megasonic relatively shows with table:
| Conventional ultrasound | Megasonic | |
| Frequency | ??15～120khz | ??800～1000khz |
| The piezoelectric energy-conversion modulator material | Lead-zirconates | -titanate |
| Wavelength | ??100mm～12.5mm | ??1.88mm～1.5mm |
| Remove particle diameter | ??≥0.4μm | ??≥0.2μm |
| Noise | Have | Do not have |
| Damage | Have | Do not have |
| Range of application | The industry semiconductor | Semi-conductor industry |
In sum, in the design of present processor for ultrasonic wave,, can't reach desirable shortcomings such as cleaning performance so exist in the operating process always because it is ultrasonic often to adopt single low frequency long wave or single high frequency to carry out.

The specific embodiment
For making purpose of the present invention, content and advantage clearer,, the specific embodiment of the present invention is described in further detail below in conjunction with drawings and Examples.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Embodiment 1
Present embodiment specifically describes a kind of processor for ultrasonic wave with mixed wavelengths provided by the present invention, and described processor comprises rinse bath and at least one ultrasonic vibrating box;
Described ultrasonic vibrating box places described rinse bath inside;
As shown in Figure 1, described ultrasonic vibrating box comprises at least one million frequency shortwave supersonic generator and at least one low frequency long wave supersonic generator.
Described ultrasonic vibrating box places described bottom of rinse bath or inner side.
About the riding position of ultrasonic vibrating box in rinse bath inside, this is because ultrasonic wave also has the branch of compressional wave and shear wave, and shear wave can not be propagated in liquid and gas medium, and this is because liquids and gases do not have shear elasticity.Simultaneously because the frequency of ultrasonic height, thereby wavelength is very short, and it can be along straightline propagation, thereby make the emission ultrasonic wave only towards a certain definite direction; In order better to reach treatment effect, reduce the dead angle of cleaning, so the plan supersonic generator be placed in the liquid in bottom, sidepiece or the rinse bath of rinse bath, thereby reach better treatment effect.
In addition, the hyperacoustic sound wave of the megahertz level direction of propagation is parallel to and is cleaned object surface, so intend making it parallel, thereby can reaching better treatment effect in the liquid in bottom, sidepiece or the rinse bath that ultrasonic generator is placed on rinse bath with the object surface that is cleaned.
Described million frequently take evenly distributed at random between shortwave ultrasonic generators and the low frequency long wave ultrasonic generator or intersect evenly distributed mode to place described ultrasonic vibrating box inside.
The ultrasonic vibrating box that is comprised in the described rinse bath is two groups or three groups, described two groups or three groups of ultrasonic vibrating box are two dimension each other in described rinse bath inside or 90 ° of three-dimensional azimuth positions are provided with.Concrete arrangement mode is decided according to being cleaned the concrete condition of object.
Send power that device sends and can not reach and clean when needing in that single group mixed wavelengths is ultrasonic, can increase by second group, the 3rd group mixed wavelengths ultrasonic generator, second group or the 3rd group of ultrasonic vibrating box is two dimension each other in described rinse bath inside or 90 ° of three-dimensional azimuth positions are provided with.Thereby reduce the dead angle of cleaning, to reach the cleaning performance that needs.
Described million frequency shortwave ultrasonic generators and low frequency long wave ultrasonic generator are worked or alternation simultaneously.
Million frequently the shortwave supersonic generators and low frequency long wave supersonic generator acts on simultaneously or the effect of gap, front and back under, high frequency, low-frequency ultrasonic waves produce cavitation processes separately separately, when separately cavitation bubble implosion, can produce many new cavitation nucleus, the cavitation nucleus radius of these new generations may produce resonance with another frequency of sound wave, and more cavitation nucleus close with its resonant frequency can be provided for the cavitation of another supersonic frequency.Initial cavitation nucleus is provided so mutually, cavitation implosion is increased, cleaning performance is better.
The ultrasonic wave reference frequency output of described million frequency shortwave supersonic generators is 1-1500MHz;
The ultrasonic wave reference frequency output of described low frequency long wave supersonic generator is 20-100KHz.
The ultrasonic wave output wavelength scope of described million frequency shortwave supersonic generators is: 1 μ m～1500 μ m.Thereby selecting suitable wavelengths to select suitable frequency according to the space of cleaning object is one of key point of technical solution of the present invention.
Described million frequently the wavelength that sends of shortwave supersonic generators and low frequency long wave supersonic generator all less than the space of cleaning objects or all less than the diameter of emulsion droplet.
The wavelength of described million frequency shortwave supersonic generators and low frequency long wave supersonic generator is selected to determine according to the object space of being cleaned.
Described million frequently shortwave supersonic generators and low frequency long wave supersonic generator select operating frequency according to the situation of cleaning object, the equilibrium radius that makes cavitation bubble is all less than the space of cleaning objects or all less than the diameter of emulsion droplet;
Preferably, make the equilibrium radius scope of cavitation bubble be: 1 μ m～1500 μ m.
, consider to use enough big excitation acoustic pressure can't reach wavelength less than the space that is cleaned object (hole) time when ultrasonic, produce suitable bubble, the diameter that makes the bubble cavitation bubble is less than the space that is cleaned object (hole).
Because of milipore filter is that specified pore diameter range is the micropore filtering film of 0.001-0.02 micron, be 1 μ m so want the cleaning filter membranes filter opening need set the filter membrane aperture.Common emulsion droplet size is between 1～100 μ m simultaneously; Sub-micro breast emulsion droplet size is between 0.1～0.5 μ m; Nano-emulsion emulsion droplet size is between 0.01～0.1 μ m.The broken microscopic examination actual particle size 90% of using of the cell grade micro mist of Chinese medicine is less than 6 μ m, and acellular substantially form exists, and reaches the requirement of Chinese medicine breaking-wall cell.The numerical value that more than is the 1 μ m that selects according to the situation of cleaning object is considered.
When ultrasonic wave passed liquid, the microvesicle nuclear in the liquid can be with the vibration of supersonic frequency generating period.Microbubble is equilibrium radius with acoustic pressure with its radius, and the process of doing periodic oscillating movement is called stable cavitation.The μ m of unit of equilibrium radius Rr, the pass of Rr and frequency F is: F * Rr=3000, the unit K Hz of frequency, hence one can see that: equilibrium radius was 150 μ m when frequency was 20KHz, equilibrium radius is 3 μ m during frequency 1MHz.For making microbubble penetrate the following space of micron order, reach best cleaning performance, in addition in the processing of Chinese medicine, require to less than 6 μ m, so select above 1MHz in view of the above.
But excessive when ultrasonic frequency, when the sound intensity of its use can not make the bubble cavitation again, ultrasonic wavelength was less than the space of the object that is cleaned, and ultrasonic wave is not reflected, thereby penetrates the space, played cleaning action.According to λ=c/f, sound's velocity in liquid is about 1500m/s, for cleaning the space below the 1 μ m, need make supersonic frequency reach 1500MHz.
| Frequency MHz | ??1 | ??2 | ??5 | ??10 | ??15 | ??100 | ??150 | ??1000 | ??1500 |
| Wavelength μ m | ??1500 | ??750 | ??300 | ??150 | ??100 | ??15 | ??10 | ??1.5 | ??1 |
The sound intensity that described million shortwave ultrasonic generator outputs frequently and low frequency long wave ultrasonic generator are exported is more than or equal to 10W/cm
2
According to the responsiveness to sound field, ultrasonic cavitation can be divided into two types of stable cavitation and transient cavitation.
Stable cavitation is long vibrated of a kind of life-span, and is general at the lower sound intensity, promptly less than 10W/cm
2In time, produce, and localized hyperthermia's high pressure that the bubble collapse produces when closed is lower, but can cause acoustic streaming, follows microjet, radiation pressure phenomenon.
Transient cavitation is generally than high sound intensity, promptly greater than 10W/cm
2In time, produce, and finishes in 1～2 cycle.When the excitation acoustic pressure is big, suitable bubble, under action of ultrasonic waves, through several resonance cycles, collapse rapidly took place in bubble, causes pressure, temperature in the bubble sharply to raise, thereby attachment is come off when promptly bubble radius and frequency of sound wave produced resonance.Cleaning performance is better during transient cavitation.Supersonic frequency is higher, and the needed sound intensity is bigger.As under a certain sound intensity, the supersonic frequency of use is higher, because of sound wave expansion phase cycle weak point, can not produce cavitation bubble, as long as improve the sound intensity, cavitation bubble still can form so.For example will produce cavitation in water, desired power is than big 10 times when the 10kHz when 400kHz for ultrasonic frequency, and promptly cavitation is to reduce along with the rising of frequency.
For the target that reaches the ultrasonic processing of the present invention so set the sound intensity that ultrasonic generator exports more than or equal to 10W/cm
2, and do more accurately according to the purpose that processor uses and to adjust.
