FIELD: process engineering.

SUBSTANCE: invention relates to tight vertical-shaft mixers for aggressive, inflammable, toxic substances in wide temperature range to be used in chemical, petroleum and other industries. Device consists of drive, magnetic coupling connected with the shaft. The latter runs in plain bearings fitted in column mounted on mixer chamber cover. Column top part is coupled by angular branch pipe with hole in cover of the tank to feed one of fluid components and column bottom part has hole to discharge said component into tank bottom part. The number of orifices may vary but is other than one.
