Description

【0001】
【発明が属する技術分野】
本発明は、フルイ枠を振動してフルイ部材を振動する超音波フルイ装置に関するものである。
【0002】
【従来の技術】
従来、この種の超音波フルイ装置としては、超音波変換器に接続された共振子をフルイ部材のフルイ面に直接接触させたものが提案されている(特表平8−500058号公報参照)。
【0003】
【発明が解決しようとする課題】
しかしながら、このようなフルイ装置では、フルイ部材のフルイ面に接触される共振子は間が開いているもののフルイ部材の全面に接触するように構成されているため、フルイ分けする物の邪魔になり、又、フルイ分けする物が付着したり、さらに、フルイ部材に取り付けているため、フルイ部材の損傷を招いたり、構成が複雑になるという問題があった。
【0004】
【課題を解決しようとする手段】
本発明は、フルイ部材を固着したほぼ円形又は楕円形に形成されたフルイ枠と、該ほぼ円形又は楕円形に形成されたフルイ枠の内側に張り出した張り出し部に振動面を接触して固着した1つ又は複数の超音波振動子と、該1つ又は複数の超音波振動子に発振電力を供給する発振器とからなるものであり、又、前記複数の超音波振動子を位相をそろえて発振してもよいし、さらに、前記超音波振動子の取り外しを可能としてもよい。
【0005】
【発明の実施の形態】
本発明では、円形又は楕円形のフルイ枠に超音波振動子を固着することにより、フルイ枠に固着したフルイ部材をフルイ枠の周囲から均等に振動することができ、又、フルイ部材のフルイ面が全面開いているので、フルイ分けしたいものを効率よく振動させることができ、又、フルイ枠に超音波振動子が固着されているために、複数個の取り付けが可能となり、さらに、複数の超音波振動子を同位相で駆動することにより、フルイ量をパワーアップすることができる。
【0006】
【実施例】
図1は本発明の1実施例の超音波フルイ装置の斜視図、図2は図1のフルイ装置の一部断面側面図で、円形又は楕円形の枠1の一面にフルイ部材2の端部が固着され、フルイ枠1の内側に張り出した張り出し部1a、1bに超音波振動子3、4の端部をそれぞれ固着する。
【0007】
この超音波振動子3、4は圧電体振動子5を金属ブロック6、7で挟持したランジュバン型振動子によってそれぞれ構成され、この超音波振動子3、4の圧電体振動子5に発振器8から発振電力が印加される。
【0008】
このように構成した本実施例の超音波フルイ装置では、フルイ枠1の張り出し部1a、1bに固着した超音波振動子3、4の圧電体振動子5に発振器8から発振電力が供給されると、超音波振動子3、4はフルイ枠1の張り出し部1a、1bを振動することによってフルイ枠1を振動し、それによってフルイ部材2を振動するので、フルイ部材2のフルイ面が大きく開けられ、フルイ部材2を効率よく振動することができる。
【0009】
図3は、本発明の他の実施例の超音波フルイ装置の側面一部断面図で、1はフルイ枠、2はフルイ部材、3、4は超音波振動子、8は発振器であり、これらの構成は上記実施例と同じであるので、説明は省略するが、本実施例では、超音波振動子3、4の一部を防塵と絶縁のために振動子カバー9、10でそれぞれ覆うように構成している。
【0010】
このように構成した本実施例では、超音波振動子3、4に装着した振動子カバー9、10を直接持つことができるので、この振動子カバー9、10を持ってフルイ分けすることができる。
【0011】
なお、上記実施例では、フルイ枠1に超音波振動子を2つ固着したが、1つでもよいし、3つ以上でもよい。
【0012】
【発明の効果】
以上説明したように、本発明の超音波フルイ装置では、フルイ枠に超音波振動子を装着したので、フルイ部材のフルイ面に邪魔するものが無く、フルイ面が大きく開けられ、複数の超音波振動子が取り付け可能であり、さらに、複数の超音波振動子を同位相で駆動することにより、フルイ効果が増大するという利点がある。

[Technical field to which the invention belongs]
The present invention relates to an ultrasonic sieve device that vibrates a sieve frame and vibrates a sieve member.
[0002]
[Prior art]
Conventionally, as this type of ultrasonic fluid device, a device in which a resonator connected to an ultrasonic transducer is brought into direct contact with a fluid surface of a fluid member has been proposed (see Japanese Patent Publication No. 8-500058). .
[0003]
[Problems to be solved by the invention]
However, in such a sieve device, the resonator that is in contact with the sieve surface of the sieve member is configured to come into contact with the entire surface of the sieve member even though the gap is open. In addition, there is a problem that an object to be separated by the fluid adheres or is attached to the fluid member, which causes damage to the fluid member or a complicated configuration.
[0004]
[Means to solve the problem]
In the present invention , the vibration surface is fixed in contact with a fluid frame formed in a substantially circular or elliptical shape to which a fluid member is fixed, and a projecting portion projecting inside the substantially circular or elliptical fluid frame . One or a plurality of ultrasonic transducers and an oscillator for supplying oscillation power to the one or a plurality of ultrasonic transducers, and the plurality of ultrasonic transducers oscillate in phase Alternatively, the ultrasonic transducer may be removable.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, by fixing the ultrasonic vibrator to a circular or elliptical sieve frame, the sieve member fixed to the sieve frame can be evenly vibrated from the periphery of the sieve frame, and the sieve surface of the sieve member Since the entire surface is open, it is possible to efficiently vibrate what you want to divide the screen, and because the ultrasonic vibrator is fixed to the screen frame, multiple installations are possible, and By driving the sonic transducers in the same phase, the amount of fluid can be powered up.
[0006]
【Example】
FIG. 1 is a perspective view of an ultrasonic sieve apparatus according to an embodiment of the present invention. FIG. 2 is a partial sectional side view of the sieve apparatus of FIG. Are fixed, and the end portions of the ultrasonic transducers 3 and 4 are fixed to the protruding portions 1a and 1b protruding inside the fluid frame 1, respectively.
[0007]
The ultrasonic vibrators 3 and 4 are respectively composed of Langevin type vibrators in which the piezoelectric vibrator 5 is sandwiched between metal blocks 6 and 7, and the piezoelectric vibrator 5 of the ultrasonic vibrators 3 and 4 is connected to the oscillator 8 from the oscillator 8. Oscillation power is applied.
[0008]
In the ultrasonic fluidizer of this embodiment configured as described above, the oscillation power is supplied from the oscillator 8 to the piezoelectric vibrators 5 of the ultrasonic vibrators 3 and 4 fixed to the projecting portions 1a and 1b of the fluid frame 1. Then, the ultrasonic vibrators 3 and 4 vibrate the sieve frame 1 by vibrating the overhanging portions 1a and 1b of the sieve frame 1, thereby vibrating the sieve member 2, so that the sieve surface of the sieve member 2 is greatly opened. Therefore, the fluid member 2 can be vibrated efficiently.
[0009]
FIG. 3 is a partial cross-sectional side view of an ultrasonic sieve apparatus according to another embodiment of the present invention. Reference numeral 1 denotes a sieve frame, 2 denotes a fluid member, 3 and 4 denote an ultrasonic transducer, and 8 denotes an oscillator. However, in this embodiment, a part of the ultrasonic transducers 3 and 4 is covered with the transducer covers 9 and 10 for dust prevention and insulation, respectively. It is configured.
[0010]
In this embodiment configured as described above, since the transducer covers 9 and 10 attached to the ultrasonic transducers 3 and 4 can be directly provided, the fluid covers can be divided by holding the transducer covers 9 and 10. .
[0011]
In the above-described embodiment, two ultrasonic transducers are fixed to the fluid frame 1, but one or three or more may be used.
[0012]
【The invention's effect】
As described above, in the ultrasonic screen apparatus of the present invention, since the ultrasonic vibrator is mounted on the screen frame, there is no obstacle to the screen surface of the screen member, and the screen surface can be opened widely and a plurality of ultrasonic waves can be opened. A vibrator can be attached, and further, there is an advantage that a fluid effect is increased by driving a plurality of ultrasonic vibrators in the same phase.
