The invention discloses a Venturi mixing device with position-adjustable
injector holes in a
throat part. The Venturi mixing device comprises a Venturi tube front section, a Venturi tube rear section,studs, nuts, single-head bolts,
flange nuts, an
injector hole
cushion block, an adjusting
cushion block group, a front section
injector hole group, a front section bolt through hole group, a front section
flange, front section injector holes, front section bolt through holes, a rear section injector hole group, a rear section bolt through hole group, a rear section
flange, rear section injector holes, rear section bolt through holes and adjusting
cushion blocks; the adjusting cushion
block group and the injector hole cushion block are embedded into a cylindrical cavity spliced by the Venturitube front section and the Venturi tube rear section, and after the sections are fixed by the bolts and the nuts, the whole mixing device is formed; the
mixing effect of the device can be changed by changing the
insertion sequence of the injector hole cushion block in the adjusting cushion
block group. The Venturi mixing device is applicable to multiple working conditions, manpower and
time cost are saved, complete internal flow field of the device is protected, and elements in the tube are relatively convenient to clean.
