FOAM GENERATOR Russian patent published in 2002 - IPC

FIELD: equipment for technical foam generators; applicable, mainly, in manufacture of building materials. SUBSTANCE: foam generator has body, vessel for foaming agent, branch pipe with valve for dosed introduction of foaming agent, mixing chamber of variable capacity with movable wall having n holes (n ≥ 1) with diameter d with check valves, unit imparting vibrating motions to mixing chamber movable wall, branch pipe for foam discharge. Hole diameter d in movable wall is determined from expression d=6 , where d is hole diameter, mm; W is foam generator productivity, kg/cu.m; γ is design density of foam, kg/cu.m; n is number of holes in chamber movable wall; λ is vibration amplitude of movable wall, cm; ϕ is vibration frequency, Hz. EFFECT: generated foam without additional use of hydraulic pump and compressor, reduced consumption of material, labor and power resources, extended process potentialities. 1 dwg, 1 tbl
