HYDRODYNAMIC MIXER Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: mixer has a body which, in turn, has two parts in each of which a mixed fluid feed channel is fastened. The channels communicate with a mixing chamber formed between inner and outer conical surfaces of the body parts. The mixing chamber has an outlet channel which outlet hole is made in the form of an annular slot. The width of the annular slot is no more than δ = r20

-r21/2r where r₀ и r₁ are radiuses of the mixed fluid feed channels. The generatrix of the middle conical surface of the outlet channel of the mixing chamber makes an angle with the axis of the mixed fluid feed channels equal to α = r21-r20/r20-r21. The surface of the outlet channel located near the outlet hole of the annular slot has concentric projections and grooves of triangle cross section. EFFECT: improved structure. 3 cl, 1 dwg
