CONTINUOUSLY WORKING CONCRETE MIXER Russian patent published in 2017 - IPC B28C5/48 

FIELD: construction.

SUBSTANCE: housing is fixed on a platform resiliently mounted on a frame. The housing is fixed on the platform provided with a vibrator, mounted horizontally under the platform. The housing is helical and made of a hollow tunnel with multipass screw surface along the perimeter rolled along a spiral axle 0₁-0₁ around the central axis 0₂-0₂ of the spiral housing provided with helical grooves inside at the angle to its spiral axis in the form of waveform pockets with centers of curvature located alternately inside and outside of cross-section of the hollow tunnel, and is assembled of sections of rings with the same shape and size rolled from similar diamond shape bands, which accommodates trapezoids, the sides of which are located on the sides of the diamond-shaped band and upper and lower bases of the trapezoids are arranged at sharp angle to the symmetry axis of the diamond-shaped band 0₃-0₃ and they are fold lines which are located at the distance from each other equal to the length of wave-shaped pockets along the inner surface of the hollow spiral tunnel. The sections in the form of rings are interconnected by trapezia sides.

EFFECT: expansion of process capabilities, increase of productivity and product quality in the continuously working mixer.
