CONTINUOUS-ACTION CONCRETE MIXER Russian patent published in 2020 - IPC B28C5/22 B01F9/02 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for preparation of mortar and concrete mixtures. In a continuous-action concrete mixer comprising a resilient mounted on a platform mounted by means of rubber-cord pneumatic bottles on the base, a hollow housing, inside of which a tension spring is fixed, a loading and unloading device, a pipeline for supply of tempering water to the housing, the housing is screw-type in the form of installed at an acute angle α relative to truncated pyramid horizontal axis of rotation, with base in form of hexagram and with flat end face polygonal jaws, arranged at different angles ϕ and ψ to axis of rotation of truncated pyramid and to each other at angle β. Edge jaws of polygonal shape are turned along axis of rotation of truncated pyramid relative to each other by angle ω with formation along inner perimeter of helical lines and helical pockets of triangular shape along its entire length. Inside the mounted conical spring with round section of turns, which is equipped with mechanism for change of turns pitch by its expansion or compression, note here that said pipeline for tempering water supply to screw housing is mounted on discharge side by 1/2 of screw housing length.

EFFECT: expansion of technological capabilities, increased efficiency and intensity of interaction of components of mortars or concrete mixtures and tempering water in a continuous-action concrete mixer.
