MIXING DEVICE Russian patent published in 2014 - IPC B01F7/00 

FIELD: machine building.

SUBSTANCE: essence of the invention consists in the provision of reciprocating and simultaneously swinging motion of working members which cover the whole mixed medium volume when move, together with the possibility of adjusting the working members' travelling according to manufacturing process requirements. The drive of the working members in the mixing device is made as a crank-and-rocker mechanism with the rocker being provided by a radial groove where the pivot shaft of the connecting rod is installed and can move radially along the rocker axis, and additionally it is fitted by a rigidly fixed toothed section engaged with a rod having a toothed section, the rod is mounted in the guides; at least two disks are installed at one of the rod ends placed in a reactor between the stop elements, the disks are made as blade wheels able of rotating in respect to the rod axis and their blades are inclined in respect to the wheels' planes; the inclination angle of the blade plane at each wheel is made mirror-like in relation to the inclination angle of the blade planes at the adjacent wheel, the said blade wheels are mounted on the rod with the interval covering the whole mixed medium volume, and the outer blade ends are rigidly fixed on the wheel rim, and the blade inclination angle in respect to the wheel plane falls within ( 30 ÷ 60)°.

EFFECT: higher homogeneity of produced mixtures and lower power inputs in the mixing process. 2 cl, 1 dwg
