Abstract

1,189,484. Mixing apparatus. FARBENFABRIKEN BAYER A.G. 5 May, 1967 [6 May, 1966], No. 21146/67. Heading B1C. Apparatus for homogenising viscous liquids and liquids containing pulverulent material has intersecting passages through which the material is forced. The passages may be formed by external and internal oppositely - handed threads 4, 5 on a sleeve cut deep enough for them to intersect. Alternatively there may be inner and outer sleeves with outer and inner threads respectively. The apparatus shown has a rotating mandrel 3 in a tube 1, and the sleeve is fixed to the mandrel or the tube. Alternatively (Fig. 8, not shown), both tube and mandrel are fixed and the sleeve is fixed to a rotating shaft aligned with and upstream of the mandrel. Material is fed to the sleeve by a screw on the mandrel upstream of the sleeve, and the degree of mixing can be increased by varying the depths of the threads (Fig. 4, riot shown) or by recessing the threads of one screw between the points of intersection (Fig. 5, not shown). The tube, sleeve and mandrel may be cylindrical (as shown) or conical. In another embodiment the intersecting passages are formed by grooves in a flat plate which is moved through the material, or over which the material is forced.
