A solid-liquid classification device

Abstract

The invention discloses a solid-liquid grading device. The solid-liquid grading device comprises a hopper type material barrel, an overflow unit, a material supply unit, a material discharge unit, an ascending overflow rate control unit and a sediment discharge concentration control unit, the overflow unit is arranged at the periphery of a top opening of the hopper type material barrel, the material supply unit is arranged at a top inlet of the hopper type material barrel, the material discharge unit is arranged at a bottom outlet of the hopper type material barrel, the ascending overflow rate control unit stabilizes the overflow rate of the hopper type material barrel in a standard range, and the sediment discharge concentration control unit stabilizes the sediment concentration discharged from the hopper type material barrel in a standard range. The solid-liquid grading device intelligently controls the feed amount and discharge amount through using a flow rate detector to monitor the overflow rate and a concentration meter to detect the discharge concentration, realizes to grade solid particles according to a constant settling speed, realizes the precise granularity and concentration control for solid-liquid two-phase flow size grading products through full-automatic operation and control, and obtains the fine products and coarse products with high grading quality.

Description

technical field

[0001] The invention relates to the technical field of material classification, and more specifically relates to a solid-liquid classification device, especially a classification device for solid-liquid two-phase slurry that can be widely used in industries such as environmental protection, mining, metallurgy, building materials, and chemical industry. Background technique

[0002] In environmental protection, mining, metallurgy, building materials, chemical industry and other industries, it is often necessary to carry out the classification operation of solid-liquid two-phase flow slurry, especially in the pulp classification and desliming operations, it is usually necessary to separate the solid particles in the slurry slurry according to their particle size and specific gravity. Differential classification into fine-grained products and coarse-grained products. At present, the classification and desliming equipment used for solid-liquid two-phase flow slur...
