Description

【０００１】
【発明が属する技術分野】
本発明は、超音波振動子に振動子ケースに超音波振動が漏れないように充填剤を介して支持するようにした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、図３に示すように、フルイ枠１にフルイ部材２が装着され、又、フルイ枠１の張り出し部１ａ、１ｂにそれぞれ超音波振動子３、４の振動部が装着され、これらの超音波振動子３、４に発振器（図示せず）から発振出力を印加してフルイ枠１を振動し、フルイ部材２の上に載置された粉体をフルうようにしており、又、図４に示すように、フルイ枠１にフルイ部材２が装着され、フルイ枠１の上面に取り付け部材５、６を装着し、この取り付け部材５、６にそれぞれ超音波振動子３、４の振動部が取り付けられ、図３の従来例と同様に発振器（図示せず）から発振出力を印加してフルイ枠１を振動し、フルイ部材２の上に載置された粉体をフルうようにした装置を本出願人が提案した（特願平１１−１５３１４１号及び特願２０００−１９８６４４参照）。
【０００３】
【発明が解決しようとする課題】
しかしながら、このように構成した従来のフルイ装置では、超音波振動子３、４は超音波振動子３、４は何も覆っていないので、超音波振動子３、４から振動が漏れ、騒音が発生す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、フルイ枠に金網等のフルイ部材を張り、前記フルイ枠に少なくとも1つの超音波振動子を装着し、前記フルイ枠をハウジングに装着した超音波フルイ装置において、前記超音波振動子は前記フルイ枠に装着された取り付け部材に固着され、前記超音波振動子を振動子ケース内に装着し、前記超音波振動子と前記振動子ケースは前記ハウジングの外側に装着し、前記振動子ケース内の前記超音波振動子との間に充填剤を充填したものである。
【０００５】
【発明の実施の形態】
本発明では、超音波振動子を振動子ケース内に装着し、この振動子ケースと超音波振動子との間に充填剤を充填するように構成することにより、振動子ケースを介して超音波振動子からの超音波振動が漏れることがなく、又、フルイの網サイズが変更されても、振動子ケースに超音波振動が漏れない。
【０００６】
【実施例】
図１は本発明の実施例の超音波フルイ装置の側面断面図で、１はフルイ枠、１ａ、１ｂは張り出し部、２はフルイ部材、３、４は超音波振動子でこれらの構成は上記従来例と同じであるので説明は省略するが、本実施例では、フルイ部材２はハウジング７の内部に装着され、又、超音波振動子３、４は振動子ケース８の内部に挿入されて超音波振動子３、４のフランジ３ａ、４ａで振動子ケース８が支持され、これらの振動子ケース８内の超音波振動子３、４との間にそれぞれ充填剤９が挿入されている。
【０００７】
このように構成された本実施例のフルイ装置では、ハウジング７の投入口７ａから材料が投入され、超音波振動子３、４が図示しない発振装置から発振出力が印加されると、超音波振動子３、４はフルイ部材２を振動して材料をフルイ分けるが、振動子ケース８に充填剤９が挿入されているので、振動子ケース８から外部に超音波振動子３、４から発生した振動が漏れることがなく、又、フルイの網サイズが変更されても、振動子ケース８に超音波振動が漏れることがない。
【０００８】
図２は本発明の他の実施例の超音波フルイ装置の側面断面図で、１はフルイ枠、２はフルイ部材、３、４は超音波振動子、５、６は取り付け部材であり、これらの構成は上記従来例と同じであるので、説明は省略するが、本実施例では、超音波振動子は３、４は取り付け部材５、６によってハウジング７の外側に装着され、超音波振動子３、４がそれぞれ振動子ケース８に挿入され、超音波振動子３、４のフランジ３ａ、４ａで振動子ケース８が支持され、振動子ケース８と超音波振動子３、４の間に充填剤９が充填されている。
【０００９】
このように構成した本実施例の超音波フルイ装置でも上記実施例と同様に、超音波振動子３、４はフルイ部材２を振動するが、振動子ケース８に充填剤９が挿入されているので、振動子ケース８から外部に超音波振動が漏れることがなく、又、フルイの網サイズが変更されても、振動子ケースに超音波振動が漏れることがない。
【００１０】
【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、超音波振動子を振動子ケースに装着するときに、超音波振動子のフランジで振動子ケースが支持され、振動子ケース内の超音波振動子との間に充填剤を充填するように構成することにより、振動子ケースを介して超音波振動子からの超音波振動が漏れることがなく、又、フルイの網サイズが変更されても、振動子ケースに超音波振動が漏れることがないという利点がある。
