A mixing and adding device for thickener flocculant

Abstract

The invention discloses a flocculant mixing and adding device for a thickener. The slurry diversion tank is installed around the upper top surface of the central cylinder of the thickener, and the flocculant mixing and adding pipe is located at the flocculant addition point in the slurry diversion tank. Installation; the flocculant mixing and adding pipe is composed of a central pipe (6), a vertical branch pipe (8), and a horizontal branch pipe (7), the central pipe (6) is a T-shaped pipe, and the vertical branch pipe (8) Set at intervals, the upper opening of the vertical branch pipe (8) communicates with the horizontal pipe of the T-shaped pipe, and horizontal branch pipes (7) with decreasing lengths are installed on each vertical branch pipe (8) from top to bottom; the central pipe (6 ) is fixed on the crossbeam by fasteners, and the two ends of the crossbeam are buckled on the slurry diversion groove and fixed by bolts. It is connected with a flocculant addition main pipe. The invention improves the flocculant adding method and the slurry feeding method, so that the slurry and the flocculant are fully mixed, and the thickening effect of the flocculant is improved.

Description

technical field [0001] The invention relates to a mixing and adding device for liquid additives, in particular to a mixing and adding device for flocculants, which can be widely used in the fields of concentration of tailings in mine dressing plants and sewage purification treatment in industries such as steel and electric power for flocculants or other Mixed addition of additives. Background technique [0002] Tailings thickening is the most important link in mine tailings conveying and filling process. Thickener is one of the commonly used equipment in mines. It has strong working capacity and good thickening effect, and can effectively process tailings. Deep cone thickener or other high-efficiency thickener, as a kind of auxiliary equipment for mine tailings filling concentration and dehydration, has become the first choice for mine filling in recent years. This kind of thickener is easy to operate, occupies a small The capacity is large, and its application is becoming...
