SPACE MIXER Russian patent published in 2024 - IPC B01F31/30 B28C5/18 

FIELD: mixers.

SUBSTANCE: invention relates to drum-type mixing devices for mixing various bulk materials, as well as liquid components, and can be used in the agricultural, chemical, food, and pharmaceutical industries. The spatial mixer is made on the basis of a six-link spatial hinge-lever mechanism with rotational pairs, its drum is hingedly mounted on two spatial connecting rods having different geometric parameters, each of which is pivotally connected to one of the two input cranks, rigidly mounted on the shaft of its engine (gear motor), the rotation axes of the input cranks are located on the same straight line, whereas the geometric axes of the drum axles and the hinge axes of one of the input cranks are crossed at equal angles and the shortest distances between these axes are also equal, the shortest distances between the geometric axes of the hinges of the second input crank and the geometric axes of the hinges of the connecting rod associated with it are equal, and the angles of their crossing complement each other up to 180°, the geometric axes of the hinges of the second connecting rod are parallel and the shortest distance between them is equal to twice the shortest distance between the geometric axes of the hinges of the first connecting rod, the ratio of the shortest distance between the geometric axes of the hinges of each input crank to the sine of the crossing angle of these axes is equal to the ratio of similar parameters of the drum and connecting rods.

EFFECT: simplified manufacture of the mixer frame and increased accuracy of its assembly, as well as increased efficiency and intensity of the mixing process.
