PRODUCTION OF VISCOELASTIC MIX AND DEVICE TO THIS END Russian patent published in 2015 - IPC B01F3/12 B01F5/00 B01F5/12 B01F7/18 B01F13/06 

FIELD: process engineering.

SUBSTANCE: claimed process comprises separate feed of dry loose and fluid components into cylindrical vessel, fluid components being divided into separate jets to be mixed with dry loose components by rotary mixer. Obtained viscoelastic mix is discharged and vacuum is created in sealed cylindrical vessel for mixing. Said vessel is divided into two zones by perforated chamber of central mixer with pressure difference between inner and outer zones sufficient for forcing of separate fluid jets into outer zone and creating of continuously circulating flow of the mix separate jets in horizontal and vertical planes. Feed of components is made in two steps. At first step, fluid components are fed into vessel for continuous creation of fluid separate jets and dry components are fed into perforated vessel. At second step, residue of dry loose components is fed to powder the created jets with subsequent continuous mixing and blending of said viscoelastic mix. Claimed device comprises aforesaid cylindrical vessel, perforated mixer with drive, feeder of said liquid and dry loose components, device to discharge viscoelastic mix. Vessel for mixing is sealed and provided with components feed pipes and the pipe of the device for vacuum development in mixing vessel. Mixer is mounted at cylindrical vessel inclined bottom and provide with single drive shaft composed of moving rotor with helical blades and stationary stator. The latter is provided with perforated inner cylindrical vessel with top part shaped to inverted truncated cone, that is, a diffuser. Note here that dry components feeder pipe is directed into inner cylindrical vessel top part. Fluid components feeder pipe is directed tangentially to its surface from outer surface.

EFFECT: higher quality of finished mix, lower specific power consumed per unit product, lower oxidability and viscosity of mixed components, decreased oxygen content in the vessel, accelerated mixing.
