Filed: 1987-11-06
Abstract: PURPOSE:To efficiently agitate or pulverize by disposing plural agitating element combined with supersonic vibrator in a row of different phase in a tubular liquid passage and constituting a static mixer thereby. CONSTITUTION:An opening 22b of the agitating element 22 is formed to the downstream side of a fluid AB so that an emitting surface 48a of a supersonic phone 48 is directly opened in the flow passage with a result that an efficient supersonic emission is carried out; and the agitating element 22 of this static mixer gives a good agitating action to the fluid AB. Namely, a piezoelectric vibration element 36 of the agitating element 22 generates supersonic vibration due to magnetostriction by an electric excitation vibration signal sent from the outside, and this supersonic vibration is converted by the supersonic phone 48 into mechanical vibration which generates supersonic vibration in the flow passage. As a result, the colloid or solid matter in the fluid is agitated, and, in case of necessity, the solid matter can be pulverized.
