A multi-layer desliming thickener

Abstract

The invention discloses a multi-layer desliming thickener, comprising: an upper cone (1), which is in the shape of an inverted cone, and a lower distribution plate (5) is arranged at the discharge port at the bottom, and an upper settlement area is formed inside; The barrel (3) is set inside the upper cone (1), on which there is a feeding pipe (7), and an upper distribution plate (4) is arranged at the discharge port at the bottom; the lower cone ( 2), in the shape of an inverted cone, which is set outside the upper cone (1), and the bottom flow pipe (8) is provided with a slurry valve, forming a lower settlement area inside; the overflow tank (12) is located on the upper An overflow pipe (13) is provided on the periphery of the overflow port of the cone (1) and the lower cone (2). The concentrator has high desliming and concentration efficiency, large production capacity per unit area, and a single unit can achieve the effect of two or even multiple stages of thickening and desliming. Good choice for enrichment work.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a concentrator used for desliming treatment of ore pulp. Background technique [0002] Desliming and thickening are common operations in the beneficiation production process. The basic principle is to use the ore (or ore aggregate) to settle out of the slurry by its own gravity to achieve the purpose of desliming or dehydration. [0003] At present, conventional desliming and thickening equipment mainly include thickeners, desliming hoppers, inclined plate thickeners, etc. [0004] Thickener is simple in structure and reliable in production. It is a thickening and dehydrating equipment widely used in mineral processing plants in my country. When thickeners are used for desliming, especially selective flocculation desliming, due to common problems such as low desliming efficiency and difficult control, it is often necessary to use multiple thickeners in serie...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the pulp moves in the equipment, the disturbance is small, which is not conducive to the dispersion of particles in the pulp, especially when it is used in the selective flocculation desliming process, the useful minerals will entrain a large amount of gangue slime and sink, resulting in desliming Ineffective
