MIXER FOR VISCOUS COMPOSITIONS Russian patent published in 2017 - IPC B01F5/06 

FIELD: physics, instrumentation.

SUBSTANCE: invention refers to a device for viscous compositions mixing, and may find application in chemical, food, pharmaceutical, building and other industries. Mixer for viscous compositions comprises a cylindrical stationary housing in the form of a cup, with an inner mixing device with a shaft and moving drive, and a cover, wherein the mixing device is designed as a piston with radial openings fixed sliding relative to the inner wall of the cylindrical body, and the shaft is adapted for reciprocating motion, is rigidly attached to the piston and centered by a journal bearing mounted in the cover, at that, a radial hole plug is installed above the piston with a possibility of movement having the form of an additional piston on an additional shaft with seals located on the additional piston surface with a possibility to overlap the radial holes, and a discharge opening is located on the cup bottom, according to the invention , seals are formed as a monolithic rubber pad covering the entire bottom surface of the additional piston and adhered thereto.

EFFECT: invention provides improved performance of the mixer.
