Abstract

979,675. Mixing powders and liquids. BADISCHE ANILIN- & SODA-FABRIK A.G. July 4, 1962 [July 5, 1961], No. 25588/62. Heading B1C. Apparatus for mixing a powder with a liquid and especially for dissolving a flocculating agent comprises a hopper-shaped container 2 for the powder and a mixing tube 9 the axis of which is inclined to that of the powder container. Powder falls on the wall of the mixing tube and is entrained by a tangential jet of liquid from the nozzle of the pipe 12 ; the axis of the pipe makes a small angle with the normal to the axis of the tube 9 so that the mixture follows a helical path down the tube. The bottom of the tube has a constriction 11 or diaphragm shutter to control residence time therein. The mixing tube passes through an opening in a solution storage container 16. The proportions of powder and liquid may be controlled by a rotatable shutter 7 and a valve 13 respectively. The length/diameter ratio of the mixing tube 9 is preferably between 6:1 and 3: 1 and the powder container 2 may, as shown, be portable and detachable.
