DEVICE FOR MIXING BASIC AND FORMING COMPONENTS Russian patent published in 1994 - IPC

FIELD: mixers. SUBSTANCE: device doesn't require viscosity measuring during process of mixing. Viscosity is determined indirectly in form of pressure differences which are determined by means of pickup 7 mounted onto pipe 5 at line of entrance into circulation pump 6. Pickup 10 is used for determining viscosity either and mounted at the part of pipe-line 4 where final product passes. Pipe 5 is filled with reference liquid; temperature of liquid is equal to temperature of final product which passes through pipe-line 4 due to the fact that the pipe is made in form of circulation loop connected to circulation pump 6; the loop is disposed in pipe-line 4. Discharges are kept constant in pipe-line 4 and in pipe 5, as a result, proportional change in viscosity is provided, as well as changes in valued of pressure differences in pickups 7 and 10. EFFECT: improved efficiency; improved reliability of operation. 1 dwg
