FIELD: purifying industrial sewage. ^ SUBSTANCE: galvanizing cone has housing made of trancated cone whose greater base points upward. The cone is provided with the arresting grid positioned on the top face of the cone, air dispergators, relief bottom, supplying pipe, stops made of stiffening ribs, and vibration drive for setting the housing in vertical vibrations. The supplying pipe is made of either pipe with conical funnel or tangential guide. The openings of the air dispergator are made in the side of the housing and inclined to the plane of the housing base at an angle no less than 30° and no more than 40°. The dispergators can be made of perforated false bottom provided with staggered openings parallel to the housing walls. The angle of inclination of the generatrix of the cone is equal to the golden section for coefficients K = 2.618 and K = 4.236. The vibration device is made of a chamber with the rod. The block that transmits vertical vibration to the housing is mounted inside the chamber above the unbalance. ^ EFFECT: reduced cost and enhanced efficiency. ^ 7 cl, 2 dwg
