VIBRATORY CONCRETE MIXER Russian patent published in 2014 - IPC B28C5/20 

FIELD: process engineering.

SUBSTANCE: invention relates to production of mortars. Housing features helical shape with polygonal helical surface along its inner and outer edges and is composed of sections made up of two subsections. The latter are made up of bands flexed in one side along straight creases inclined to band edges and coiled to form, over band length, the different-side equilateral, isosceles and scalene triangles. Sides of triangle differ by one linear magnitude multiple of delta. Two equal scalene triangle larger sides smaller than the side of large equilateral triangle by one linear magnitude delta multiple of integer are located on both sides of the largest equilateral triangle. Smaller equilateral triangle is attached to mid side of the latter on one side of the band. All sides of said smaller triangle are smaller than said largest equilateral triangle by one linear magnitude delta multiple of two. Isosceles triangle base is attached to second side of smaller equilateral triangle, isosceles triangle lateral sides are smaller than its base by linear magnitude delta, hence, smaller than the side of the largest equilateral triangle by linear magnitude multiple of three deltas. Isosceles triangle is attached to the side of the latter, its base being smaller than its side by magnitude delta, hence, smaller than the side of largest equilateral triangle by four deltas. Lateral side of isosceles triangle with base smaller than is side by magnitude delta, hence, smaller than the side of largest equilateral triangle by three deltas, is attached to second scalene triangle mid side on band opposite side. Isosceles triangle is attached to the side of the latter, its base being smaller than its side by magnitude delta, hence, smaller than the side of largest equilateral triangle by four deltas. After coiling the band, band edges of lines magnitude smaller by four deltas than the side of largest equilateral triangle are interconnected to make subsections. Said subsections have square-like opening on their one side, opening side being smaller than that of the largest equilateral triangle by three deltas. On opposite side, they have opening shaped to isosceles trapezium with larger base equal to side of the largest equilateral triangle and smaller base smaller than larger base by three deltas. Trapezium sides are smaller than larger base by two deltas. Aforesaid subsections are connected by trapezium-shape openings to make square-like sections with inlets and outlets, square sides being equal. Said openings are arranged at an angle, its magnitude defining the working chamber helical shape. Said sections are connected with alternate turn relative to each other. Every next section is turned through 90 degrees relative to each other clockwise. Then, every next section is jointed with turn in reverse direction, also, through 90 degrees.

EFFECT: expanded operating performances, decreased overall dimensions.
