Description
Technical field
The present invention relates to a kind of space-focusing high power altrasonic transducers, belong to ultrasonic transducer technical field.
Background technique
Ultrasonic wave is propagated as a kind of mechanical wave and be unable to do without medium, and power ultrasound is mutual with medium in communication process
Effect generates a series of physical, chemical effect.It mainly include following effect: mechanical effect, fuel factor, cavitation effect, chemistry effect
It answers.So-called power ultrasound refers to that ultrasonic power is large enough to cause the ultrasonic wave of cavitation effect.
A large amount of research achievement shows power applications of ultrasound in ultrasonic cleaning, phonochemistry, ultrasonic hydrometallurgy, biology doctor
The industries such as, pharmacy have extensive prospect, but most research achievement only rests on laboratory stage, Industrialization Progress at present
Slowly.To find out its cause, at present large power supersonic using single high power altrasonic transducer, it problems brought by 1, transducing
Device service life problem: single only high-power energy converter, radiant power is larger (generally higher than 1000W, maximum reachable 3000W), this
Sample has more serious influence to the service life for the main piezoelectric element for generating ultrasonic wave, simultaneously for the other machinery knot of energy converter
Structure aging effects are also larger, and especially with the energy converter of luffing rod type, amplitude transformer is easily broken；2, power ultrasonic transducer
Ultrasonic erosion problem: why large power supersonic is widely studied, applies, exactly because of a series of physical of its generation, chemistry
Effect, these effects are similarly effective to ultrasonic transducer, cause ultrasonic transducer radiation head to generate serious ultrasonic erosion and ask
Topic, even if ultrasonic transducer is just etched into bee using two or three months in weak acid, aqueous slkali using titanium golden material entirely in practice
Nest shape；3, biology, pollution problem of the ultrasonic transducer to processed sample in pharmacy: such as pharmaceutical extraction with separate, it is biodegradable,
During biological cell crushes, because high power altrasonic transducer radiating surface directly contacts processed sample, pollution can be generated to processed sample.
Summary of the invention
The present invention provides a kind of space-focusing high power altrasonic transducer, passes through conjunction using more small-power ultrasonic transducers
The space layout of reason generates high-power ultrasonics in space-focusing region；It can effectively solve the problem that single high power altrasonic transducer
The bring above problem.
The technical scheme is that: a kind of space-focusing high power altrasonic transducer, including small-power ultrasonic transducer 1,
Container 2；It is evenly arranged in 2 outer surface of container along horizontal circumferencial direction by several small-power ultrasonic transducers 1, forms one group of sky
Between focused transducer group；Several small-power ultrasonic transducers 1 of this arrangement generate in space-focusing region is greater than 1000W
High-power ultrasonics.
Further, the small-power ultrasonic transducer 1 is the ultrasonic transducer that power is less than 100W.
Further, several small-power ultrasonic transducers 1 sound intensity size according to needed for 2 size of container and focal zone
Select 1 number of small-power ultrasonic transducer be 2,3,4 ... or n only.
Further, the container 2 is liquid solution container, and material is metal or glass, and shape is round, cone
Or regular polygon.
Further, the small-power ultrasonic transducer 1 uses epoxy glue Nian Jie or works as container 2 with 2 connection type of container
It is screwed also to be adopted when metal material, junction has avoided gap, bubble, is filled using epoxy glue or other coupling materials
Junction.
Further, several small-power ultrasonic transducers 1 in one group of space-focusing energy converter group are same flat
On face, it is equal that acoustic beam reaches center of circle geometric distance；Same group of space-focusing energy converter group is driven using the same supersonic generator
It is dynamic.
Further, the space-focusing energy converter group has multiple groups, arranges in the vertical direction of container 2 respectively, is hanging down
Histogram is to multiple focal zones are generated, and Multi-point focusing region generates high-power ultrasonics in container 2.
The working principle of the invention is:
Sound waves more than two beams or two beams such as meets same frequency, same-phase condition in space point in communication process and produces
Raw space overlapping.The result of superposition, which assembles the sound wave, enhances focusing i.e. mentioned here, as described below:
Ultrasonic wave acoustic pressure of space certain point during spatial may be expressed as:
P=Asin (ω t+ φ) (1)
N beam ultrasonic wave, respective acoustic pressure are respectively as follows:
Two beams or the above ultrasonic wave of two beams are when space point is assembled, convergent point acoustic pressure:
P=p1+p2+…+pn
=A1sin(ω1t+φ1)+A2sin(ω2t+φ2)+…+An sin(ωnt+φn) (2)
If met: ω1=ω2=...=ωn=ω；φ1=φ2=...=φn=φ (3)
Then (2) formula:
P=(A1+A2+…+An)sin(ωt+φ) (4)
That is two beams or the above ultrasonic wave of two beams such as meet ultrasonic frequency and the equal feelings of phase when space point is assembled
Under condition, the acoustic pressure of convergent point is equal to the sum of each beam ultrasonic wave acoustic pressure amplitude.
It is derived according to above-mentioned theory, to meet each beam ultrasonic wave same frequency condition at centre point: n energy converter of horizontal direction
Focused transducer group is formed, same group of focused transducer is driven using the same driver.Meet each Shu Chaosheng at centre point
Wave same-phase condition: it should ensure that energy converter is arranged in same level, it is equal that acoustic beam reaches center of circle geometric distance.In addition each super
The ultrasonic beam of acoustic wave transducer transmitting is not straight line, and acoustic beam has certain angle of release, so in the center point focusing ultrasonic wave
It is not a point, but a region, so being called focal zone.
The present invention is evenly arranged in 2 outer surface of container, composition one along horizontal circumferencial direction by more small function ultrasonic transducer 1
Group space-focusing energy converter can be as shown in Figure 1.As needed multiple focal zone vertical direction that can arrange multiple groups energy converter group such as Fig. 2 institute
Show.The present invention generates high-power, super large function in space-focusing region by space layout using more small-power ultrasonic transducers
Rate ultrasonic wave.
The beneficial effects of the present invention are: the present invention reduces single supersonic transducer power by space-focusing mode, together
When reduce transducer face oscillation intensity, reduce the ultrasonic erosion of energy converter, improve ultrasonic transducer use the longevity
Life can avoid ultrasonic transducer and directly contact with processing liquid, can eliminate pollution of the ultrasonic transducer to processed sample.This hair
It is bright can be used for being cleaned by ultrasonic, phonochemistry, ultrasonic hydrometallurgy, biomedicine, the industries such as pharmacy.
