Slurry concentrating and stirring device

Abstract

The invention relates to a slurry concentrating and stirring device which comprises a stirring tank, an inclined plate device and a distribution tank, wherein the bottom of the stirring tank is provided with a discharge port, and the upper end of the discharge port is open; a stirring mechanism is arranged on the inner bottom wall of the stirring tank; the stirring mechanism is in transmission connection with a stirring driving device; the inclined plate device is arranged in the open end of the stirring tank; the distribution tank is arrange above the stirring tank, the bottom of the distribution tank is provided with a blanking channel, and a feeding control mechanism is arranged at the blanking channel; the blanking channel communicates with ore dividing pipes respectively; a pluralityof blanking pipes are uniformly distributed at the lower end of each ore dividing pipe correspondingly, a distribution plate is horizontally arranged between the upper end of the inclined plate deviceand each blanking pipe correspondingly, and a plurality of throttling holes are uniformly distributed in the distribution plate; the open end of the stirring tank is circularly provided with an overflow weir, and the horizontal height of the distribution plate is higher than that of the upper end of the overflow weir; and an overflow groove is circularly arranged on the outer side wall of the open end of the stirring tank. The slurry concentrating and stirring device provided by the invention has the advantages that the inclined plate device and the stirring tank are integrated, the occupiedarea is small, the cost is low, the concentration efficiency is high, and the operation and maintenance costs are low.

Description

technical field [0001] The invention relates to slurry concentration technology, in particular to a slurry concentration stirring device. Background technique [0002] At present, in the beneficiation process, ordinary thickeners or inclined plate thickeners are often used to concentrate the ore pulp. The concentrated slurry is sent to tailings ponds or large mixing tanks for storage through pumps and pipelines, and then transported through pipelines. To the next process, the adjustment of the concentration is completed through an independent water supply system and a detection system. This process has been widely used in the iron ore concentrate pipeline transportation system. The ordinary thickener and inclined plate thickener used need to be installed independently and occupy a large area. The feeding and discharging need to be transported through pumps and pipelines, which requires a large investment and High energy consumption. [0003] In addition, inclined plate thi...

Problems solved by technology

This process has been widely used in the iron ore concentrate pipeline transportation system. The ordinary thickener and inclined plate thickener used need to be installed independently and occupy a large area. The feeding and discharging need to be transported through pumps and pipelines, which requires a large investment and high energy consumption

[0003] In addition, inclined plate thickeners are widely used in tailings treatment and sludge treatment. CN102228750B discloses a high-efficiency inclined plate thickener, which consists of an upper inclined plate device and a box-shaped cone with a stirring device in the lower part. The upper part is fed directly and concentrated in the inclined plate device. The concentrated slurry is accumulated in the cone and discharged through the lower outlet. This kind of equipment cannot control and adjust the concentration of the concentrated slurry in the cone, which cannot meet the requirements of the subsequent processes. Stable slurry concentration is required, so this equipment has a concentration function and does not have a concentration control adjustment function

[0004] In addition, the feeding methods currently used in the inclined plate thickener include upper feeding (CN102228750B, CN203634873U), middle feeding (CN203724821U), and lower feeding ["Metal Mine" 2010 No. 7 "Solid particles in oblique narrow flow Research on Deposition and Slipping on Inclined Plate Surface” mentions three ways that “the feed slurry enters from the lower part of the side of each oblique narrow flow monomer along the horizontal direction…”], these three feeding methods are all suitable for The settlement of fine particles in the slurry produces a large disturbance, which is not conducive to the settlement of fine particles, reducing the concentration effect and overflow water quality
