DEVICE FOR FINING AND DISPERSING FOAM

摘要

PURPOSE:To provide the titled device having an excellent effect of fining and dispersing foam by the constitution in which plural grooves from the aperture to the circumferential edge and a vertical recess between the apertures of the grooves on the circumferential surface of a rotating body are provided to the base of the rotating body to stir the foam released from the apertures in the recess. CONSTITUTION:Plural grooves 5 from the aperture part of a gas supply path 2 to the circumferential edge thereof are radially provided to the base of a rotating body 10 and a recess 11 of which the bottom end is opened to the circumferential edge part at the base of the body 10 is provided between the apertures of the respective grooves 5 on the circumferential surface of the body 10 in a device for fining and dispersing foam consisting in attaching the body 10 to the bottom end of a vertical revolving shaft 3 having internally the path 2. The body 10 is rotated at a high speed via the shaft 3 in an arrow C direction in the liquid in a tank 1. The gas supplied from the path 2 is then passed through the aperture of a through-hole 7 then through the grooves 5 into the liquid by which the gas is made into foam. The foam is further vigorously stirred by the recess 11 at the velocity higher than the velocity of the flow D of the liquid, by which the foam is fined and is dispersed into the liquid.
