柱を音波で振動させるようにしたものである。More specifically, a unit is made by fixing a sieve screen to a cylindrical sieve screen frame with strong tension, and these are stacked on top of each other in several tiers, and a rubber plate is placed in place of the screen on the cylindrical sieve screen frame at the bottom tier. A saucer fixed with strong tension, and a rubber plate fixed to the front of the speaker at the top, are stacked one on top of the other to maintain an airtight interior, and the air column formed inside is made to vibrate with sound waves. This is what I did.

この孔８ａによって受皿３のゴム板４の振動による風圧
を逃げることができるが、該孔８ａ・・・・・・の全面
積は受台８の側壁面積の２０〜４０％にしである。The holes 8a allow wind pressure caused by the vibration of the rubber plate 4 of the tray 3 to escape, but the total area of the holes 8a is 20 to 40% of the area of the side wall of the tray 8.
また該孔８ａ・・・↓・・は受台８の側面の全体にわた
って軸対称になるよう分布され、これによって受皿ゴム
板４・が円滑に振動できるようになっている。Further, the holes 8a...↓... are distributed axially symmetrically over the entire side surface of the pedestal 8, thereby allowing the pedestal rubber plate 4 to vibrate smoothly.
９はゴム、板下敷である。9 is a rubber, board underlay.
１０は音波発生器で、球面状カバー１１で覆われている
。10 is a sound wave generator, which is covered with a spherical cover 11.
１２は音生器の把手である。１３は振動ゴム板で、フラ
ンジ１４にとりつけられている。12 is a handle of the sound generator. 13 is a vibrating rubber plate, which is attached to the flange 14.
振動ゴム板１３はふるい網枠と同一直径の口径を有し、
３０〜３００．Ｈｚの振動数をもつスピーカ１５の前面
に強い張力で張られている。The vibrating rubber plate 13 has the same diameter as the sieve screen frame,
30-300. It is stretched with strong tension in front of a speaker 15 having a frequency of Hz.
１６はふるい接続フランジで前記フランジ１４に固着さ
れ、Ｏリングを介し最上段のふるい網枠１の上面に密着
できるようになっている。A sieve connecting flange 16 is fixed to the flange 14 and can be closely attached to the upper surface of the uppermost sieve screen frame 1 via an O-ring.
１７はコネクタで、これにより図示されない音波発信器
に接続される。17 is a connector which is connected to a sonic wave transmitter (not shown).
以上の構成を有する気柱振動ふるいは次の如く作動する
。The air column vibrating screen having the above configuration operates as follows.
（１）音波発信器に音波発生器１０を接ぎ、電源コード
を差込む。(1) Connect the sonic generator 10 to the sonic generator and insert the power cord.
（２）受台８の上に受皿３を重ね、次に必要なふるい網
枠１を重ねる。(2) Stack the saucer 3 on the pedestal 8, and then stack the necessary sieve frame 1.
（３）最上部のふるい網枠１に試料を入れ、音波発生器
１０を重ねる。(3) Put the sample into the top sieve frame 1 and stack the sonic generator 10 on top of it.
（４）タイマー（図示せず）をセットし、電源スィッチ
を入れる。(4) Set a timer (not shown) and turn on the power switch.
（５）出力ダイヤルを最高にし、周波数ダイヤルを回す
と、周波数が高くなり脈動気流が発生し、ふるい分けが
開始される。(5) Set the output dial to the highest level and turn the frequency dial to increase the frequency, generate a pulsating airflow, and begin sieving.
（６）タイマーの設定時間が終了すると、音波が停止す
る。(6) When the timer setting time ends, the sound waves stop.
本考案に係るふるいを使用すると、１００メツシュ以下
数ミクロンまでの微粉体のふるい分けが可能である。When the sieve according to the present invention is used, it is possible to sieve fine powder of 100 mesh or less down to several microns.
空気柱の振動によって粉体の分散効果が優れているので
、ふるい分けがきわめて効果的に行われる。Since the vibration of the air column has an excellent dispersion effect on the powder, sieving is performed extremely effectively.
又ふるい装置内は気密状態が維持されているので、粉塵
の発生がない。Furthermore, since the inside of the sieving device is kept airtight, no dust is generated.
ふるい網２は密閉された気柱の振動即ち音波による空気
の脈動気流を利用によって振動するので、網枠には僅か
の振動しか伝わらず、網枠の破損の心配は全くない。Since the sieve screen 2 vibrates by utilizing the vibration of a sealed air column, that is, the pulsating flow of air caused by sound waves, only a small amount of vibration is transmitted to the screen frame, and there is no fear of damage to the screen frame.
さらに潤滑油等を一切使用しないので、清潔なふるい分
けが可能である。Furthermore, since no lubricating oil or the like is used, clean sieving is possible.
