本発明は、接触形電界カーテンの原理を応用した粒子の
混合・分散方法およびその装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a particle mixing and dispersion method applying the principle of a contact type electric field curtain and an apparatus therefor.
〔従来の技術］
接触形電界カーテンは、特公昭５４−１２６６７号（接

る。[Prior Art] A contact type electric field curtain is a group of electrodes for configuring an electric field curtain, as described in Japanese Patent Publication No. 12667/1983 (Method for Configuring a Contact Type Electric Field Curtain and Contact Type Electric Field Curtain Device Using the Same). A dielectric layer is placed in close proximity to or in contact with the dielectric layer, and a light moving object on the dielectric layer obtains a contact charge due to contact charging with the surface of the dielectric layer, receives the electrodynamic action of the electric field curtain, and generates a dielectric It is driven by repulsion from the body layers.
これを第６図により説明する。This will be explained with reference to FIG.
互いに絶縁した棒状あるいは円環状の電界カーテン形成

交番不平等電界は、言うまでもなく、その大きさ、方向
とも空間的に変化しており、かつ、時間的には正弦的に
その方向が交番して、交番不平等電界列となっている。By arranging mutually insulated rod-shaped or annular electric field curtain forming electrodes a in a row and applying an alternating voltage between the adjacent electrodes 8, an electric force as shown by the dotted line in the figure is generated within each electrode a. An alternating unequal electric field with IIC is formed. Needless to say, the alternating unequal electric field with lines of electric force formed between the electrodes 8 changes spatially in both magnitude and direction, and its direction changes sinusoidally in time. This results in an alternating unequal electric field array.

って振動し、その振動の半周期ごとに力線Ｃに垂直な外
向き方向の脈動的遠心力を受ける。その結果として粒子
には平均遠心力１”ｃが作用する。When a charged particle approaches this electric field region, it receives an alternating electric force in the direction along the electric field line C, and vibrates along the curved electric field line C, and every half period of the vibration, the field line C changes. It is subjected to a pulsating centrifugal force in a vertical outward direction. As a result, an average centrifugal force of 1''c acts on the particles.

界の弱い場所では電極ａに向かう方向の電気力を受ける
結果、粒子には、その差として電極から遠ざける方向の
電気力線Ｃに沿った平均グレーディエントカＦ９が作用
する。In addition, the vibration phase of particles is due to vibration in a viscous medium, so in a place where the electric field is strong near electrode a, the electric force in the direction away from electrode a is reversely applied to the electric field far from electrode a. As a result of receiving an electric force in a direction toward the electrode a at a weak location, an average gradient force F9 along the electric force line C in a direction away from the electrode acts on the particle as a difference between the electric forces.

で、ともに電界が不平等でかつ交番的であることから生
じる。両者の合成力として、電極列から遠ざける方向の
電気力学的反撥力Ｆ「が粒子に作用する。The average centrifugal force 1"c is due to the spatial change in the direction of the force ac (curvature), and the gradient force Fg is the acting force generated due to the spatial change in the density of the field lines C (field strength gradient). Both occur because the electric fields are unequal and alternating.As a resultant force of both, an electrodynamic repulsive force F'' in the direction away from the electrode array acts on the particles.

。When a dielectric layer is placed in this electric field region, particles are charged by contact charging as soon as they adhere to the dielectric layer and come to float from the dielectric layer due to the electrodynamic repulsion described above.
