DIFFERENTIAL MIXER Russian patent published in 2021 - IPC B01F9/06 

FIELD: mixing.

SUBSTANCE: invention relates to apparatuses for mixing bulk materials and can be used in production of compound feeds, chemical, building, and food industries. A differential mixer for mixing bulk materials, containing a mixing drum container 2, equipped with trunnions, wherein, by means of one of the trunnions, said container is hingedly connected with a connecting rod 3 hingedly connected with a driving crank 4 hingedly connected with a drive 7, and by means of another trunnion, the drum container 2 is hingedly connected with a driving crank 1 hingedly connected with a drive 6, wherein the axes of the supports of the cranks are located on a single straight line, and the mixing drum container 2 is capable of performing spatial uneven, adjustable during operation, movement by means of the two driving cranks, satisfying the ratio

,

and the conditions of l₁ = l₃; l₂ = l₄; α₁ = α₃; α₂ = α₄, wherein l₁ is the shortest distance between the geometric axes of the hinges of the driving crank 1; l₂ is the shortest distance between the axes of the trunnions of the drum 2; l₃ is the shortest distance between the geometric axes of the hinges of the connecting rod 3; l₄ is the shortest distance between the geometric axes of the hinges of the driving crank 4; α₁ is the angle of crossing of the geometric axes of the hinges of the driving crank 1; α₂ is the angle of crossing of the geometric axes of the trunnions of the drum 2; α₃ is the angle of crossing of the geometric axes of the hinges of the connecting rod 3; α₄ is the angle of crossing of the geometric axes of the hinges of the driving crank 4.

EFFECT: proposed structure provides a possibility of increasing the manufacturability and assemblability of the mixer, intensifying the mixing process, increasing the homogeneity of the mixture.
