MIXER FOR VISCOUS LIQUIDS Russian patent published in 2017 - IPC B01F7/16 

FIELD: machine engineering.

SUBSTANCE: mixer contains a housing with a cover, a drive, two working shafts pivotally connected to two cranks, one of which is fixed to the drive shaft, and the other is hinged on the wall of the housing and fixed with blades on the shafts and cranks. Working shafts and cranks have a special arrangement of geometrical axes of hinges and the shortest distance between them. So, the leading crank has an angle α₁ of crossing and the shortest distance ℓ₁, driven crank - angle α₄=180°-α₅ and the distance ℓ₄= ℓ₅, the first working shaft is the angle α₂=180° and the distance ℓ₂=2ℓ₄, the second working shaft is the angle α₃=α₁, the distance ℓ₃= ℓ₁, angle α₅>α₁ between the shafts of rotation of the cranks, the distance between them ℓ₅=ℓ₄, the relationship between the parameters of the cranks - ℓ₄=ℓ₅=sinα₁/sinα₄. With this design, the agitator provides an intensification of the mixing process by the volume action of the blades and additional inertial force action on the liquid.

EFFECT: considerable increase in the homogeneity of the mixture and an increase in the mixing capacity.
