Obtained result is analyzed, and by the model analysis to ultrasonic transformer and parameter optimization, obtains the modal parameter of ultrasonic transformer then
Design is optimized to ultrasonic transformer, it is more met practical application.
The application of ultrasonic wave plays the role of very big for chemical research development.Japan's assistant good hero et al. proposition long nineties
Sandwich torsional transducer structure.Flexural vibrations ultrasonic transformer and torsional vibration horn then are have developed again, expands industry
Application.There is equal thickness or the dish type or annular plate concentrator of Varying-thickness in the application such as large power supersonic cold-drawn fiber tube；
Large-size massive horn is have developed in ultrasonic bonding and cutting again.More at present is the amplitude transformer of probe, but
It is especially desirable to be that effect is not, so being improved to amplitude device, turns into a kind of trend.
And in high sound intensity applications of ultrasound, in such as ultrasonic wave processing, ultrasonic bonding application, relevant ultrasonic wave becomes at present
The design of width bar, method include conventional analytic method, equivalent circuit method, method of substitution (the equal method of mechanical impedance), transfer matrix method,
FInite Element and Apparent elasticity method etc..But ultrasonic transformer performance expression is answered in the method for these traditional design ultrasonic amplitude transformers
It is miscellaneous, calculate and design efforts would is all very big, so that grinding to ultrasonic transformer, the especially compound some acoustic characteristics of multistage ultrasonic transformer
Study carefully more difficult.

Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of new type ultrasonic amplitude rod devices, the amplitude rod devices monnolithic case is in cylinder.Institute
Stating amplitude rod devices includes the solid elongate body of the longitudinal axis, and the solid elongate body is in cylindrical shape, and the distal diameter is 40mm.
One end flare of the longitudinal axis is distal end, and it is near-end that the other end, which sets socket attachment structure,.It is described socket attachment structure be in
Cylinder, the cylinder diameter are 48mm, and trapezoidal cylinder transition is used between the socket attachment structure and solid elongate body.Institute
The material of ultrasonic activation can be used by stating solid elongate body use.The full-length of the solid elongate body is with selected supersonic frequency
By the single wavelength of the ultrasonic wave of the material, percentage of the error range in full-length before and after the length of the solid elongate body
One of.In this case, the solid elongate body eigentone of the amplitude rod devices and ultrasonic vibration frequency are equal,
Allow for amplitude rod devices and be in resonance state, so as to so that the distal end of amplitude rod devices, which obtains bigger amplitude, reaches more preferable
Vibrating effect.In addition material can influence the transmission of the energy of ultrasonic vibration, and the transmission effect of different materials is different therefore selected
Material needs to have following feature, and material first must have good acoustical behavior, endurance life and mechanical q-value
Height, density and acoustic loss are low, and can bear larger vibration frequency amplitude and Oscillation Amplitude, in order to improve the sound of ultrasonic transformer
Performance is learned, the forging machine direction of material and the direction of transfer of ultrasonic wave are identical.The Q values represent resonance electricity in circuit
The quality factor on road, the higher electric current under certain frequency deviation of Q values declines faster, and its resonance curve is more sharp.That is it is electric
The selectivity on road is determined by the quality factor Q of circuit, and Q values more high selectivity is better.Therefore the amplitude rod devices are adopted
Use titanium alloy material.
In actual use, described amplitude rod devices one end is connected to ultrasonic transducer, and its distal end is immersed in ultrasonic liquid,
It is because being advantageous to increase ultrasonic activation to the propagation as liquid medium and ultrasonic transformer distal end presents horn-like.And
Different ultrasonic transformers has a best frequency values, shape of ultrasonic transformer etc. all to produce certain influence to frequency, and adopts
It is in cylinder with entirety so that become succinct for function ultrasonic transformer performance expression, calculate and design efforts would substantially reduces.
The ultrasonic transformer can be applied to many places field, such as ultrasonication sludge, can strengthen the effect of processing, reduce
Moisture percentage in sewage sludge.Concrete operation step is as follows：
1）Acidification step：Object to be processed will be needed to carry out the immersion treatment under sour environment, the PH of the sour environment
Value is in 2-3.
2）Fenton processing step：To step 1）The object handled carries out the Fenton's reaction processing i.e. sulfuric acid of certain time
Ferrous iron adds the immersion treatment of hydrogen peroxide.
3）Sonicating step：By step 2）The ultrasonication of the obtained progress amplitude rod devices.
Be ultrasonically treated originally using common ultrasonic transformer relatively after it can be found that under similarity condition handle after,
More preferable dehydrating effect can be obtained using new ultrasonic variable amplitude bar, this has very big advantage when handling sludge dewatering.
Year-on-year treatment effect enhances by about one time.
In summary, particle displacement or speed amplification of the ultrasonic variable amplitude bar mechanical oscillation, and ultrasonic energy is concentrated
On less area, that is, cumulative action is played, and the Oscillation Amplitude on ultrasonic transducer radiating surface is in supersonic frequency 20kHz
Scope interior energy is expanded to tens to hundreds of microns, several microns of remote ultra-traditional.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, without departing from the inventive concept of the premise, can also make some improvements and modifications, these improvements and modifications also should be regarded as
In the scope of the present invention.
