MD3887G2 - Cycle-type mixer - Google Patents

Abstract

The invention relates to the mechanical engineering, particularly to the cycle-type mixers and can be used for preparing dry, semidry, mortar and concrete plastic or stiff mixes.The cycle-type mixer comprises a double chute (1) and, mounted therein, two horizontal shafts (2), (3), on which there are fixed mixing members (4). The mixing members (4) are made in the form of bars, radially fixed in staggered order, forming four or more longitudinal rows, and placed so that the planes of rotation of each transversal row of bars of the first shaft (2) are between the planes of rotation of the transversal adjacent rows of bars of the second shaft (3) and vice versa. The axial distance between any two transversal rows of adjacent bars belonging to different shafts and the distance between the bar ends of one shaft and the surface of the other shaft is greater than the dimension of the largest particles of the mix. The distance between the axes of the shafts (2), (3) is smaller than the sum of two bar radii and greater than the sum of the shaft diameter and the bar radius. Additionally on the shafts (2), (3), next to the lateral walls of the double chute (1), there are fixed radial scrapers (5) with the slope angle equal to 45° about the axis of the shaft, and situated on the first shaft (2) with right slope on the left part of the mixer and with left slope on the right part, and on the second shaft (3) - conversely.
