Abstract
The utility model discloses a pulp thickening device in an iron ore separation process. The pulp thickening device comprises a high-efficiency sloping panel thickening hopper and a high-efficiency thickening machine, wherein the high-efficiency thickening machine is positioned below the high-efficiency sloping panel thickening hopper, and an overflow hole of the high-efficiency sloping panel thickening hopper is connected with a pulp inlet of the high-efficiency thickening machine. According to the pulp thickening device in the iron ore separation process, pulp firstly passes through the high-efficiency sloping panel thickening hopper, wherein materials with large granularity (+0.074mm) and high settling velocity firstly pass through the high-efficiency sloping panel thickening hopper for settling and concentration, and materials with small granularity (-0.074mm) and low settling speed enter the high-efficiency thickening machine through the overflow hole of the high-efficiency sloping panel thickening hopper for secondary concentration, and therefore, base flow of the high-efficiency sloping panel thickening hopper and the high-efficiency thickening machine can both meet the concentration requirement of subsequent separation operation of pulp. The pulp thickening device disclosed by the utility model is suitable for concentration of pulp with large material granularity (generally the content of materials of -200 meshes being less than 60 percent) and high specific weight of metallic minerals.

Background technology
Existing slurry concentrating device mainly contains following two kinds of forms:
1, the slurry concentrating device of cyclone+concentrator
The treating capacity of the cyclone in this slurry concentrating device is less, and need to configure the slag stock pump when operation, and to meet its feed force, so operating cost is higher, and production operation difficulty and plant maintenance amount are all larger.The cyclone overflow enters concentrator while carrying out secondary concentration, and the size of needed concentrator is larger, and this can increase the concentrator floor space.
2, adopt the slurry concentrating device of concentrator
Whole ore pulps of this slurry concentrating device all enter in Hhigh-efficient thickener, the specification of needed concentrator is larger, production adaptability is poor, when ore properties changes, cause the ore deposit amount and the granularity that enter concentrator all to change, easily cause concentrator to press rake, to production, cause adverse effect.
In addition, for the ore pulp of granularity-200 order content between 30～60%, ore pulp enters after concentrator because the large or fine granule sinking speed differs greatly, and causes overflow water water quality poor, and the generation of pressing the rake phenomenon is often arranged, and causes beneficiation flowsheet normally to produce; Therefore, how to concentrate this material and guarantee the normal operation of system and reduce production costs, and raising production capacity is that one of ordinary skill in the art have problem to be solved always.
Summary of the invention
In view of this, the purpose of this utility model is to provide the slurry concentrating device in a kind of iron ore dressing process, this slurry concentrating device not only can meet the requirement of slurry concentrating, and has advantages of and produce stable, investment and operating cost is low and production capacity is high.
For achieving the above object, the utility model provides following technical scheme:
Slurry concentrating device in a kind of iron ore dressing process, comprise the dense bucket of efficient swash plate and Hhigh-efficient thickener, described Hhigh-efficient thickener is positioned at the below of the dense bucket of described efficient swash plate, and the overfall of the dense bucket of described efficient swash plate is connected with the ore pulp entrance of described Hhigh-efficient thickener.
Further, the outlet of the underflow of the dense bucket of described efficient swash plate is collaborated with the underflow outlet of described Hhigh-efficient thickener.
Further, the overfall of described Hhigh-efficient thickener is connected with the ring water supply system.
Further, the area of the dense bucket of described efficient swash plate is 400m
2, the diameter of Hhigh-efficient thickener is 32m.
The beneficial effects of the utility model are:
Slurry concentrating device in the utility model iron ore dressing process, at first ore pulp passes through the dense bucket of efficient swash plate, wherein granularity large (+0.074mm) and sinking speed faster material first by the dense bucket sedimentation concentration of efficient swash plate, and in ore pulp, granularity less (0.074mm) and the slower material of sedimentation enter Hhigh-efficient thickener by the overfall of the dense bucket of efficient swash plate and carry out secondary concentration, so, efficiently the underflow of the dense bucket of swash plate and Hhigh-efficient thickener all can meet the concentration requirement that ore pulp carries out follow-up sorting operation; The slurry concentrating of the metalliferous mineral that in the applicable ore pulp of slurry concentrating device of the present utility model, raw meal particle size thick (-200 order content are less than 60% usually) and proportion are larger;
Therefore, slurry concentrating device of the present utility model not only can meet the requirement of slurry concentrating, and under the work compound of the efficient dense bucket of swash plate and Hhigh-efficient thickener, has advantages of to produce stable, investment and operating cost is low and production capacity is high.
Ore pulp, after the dense bucket once concentration of efficient swash plate, can greatly reduce the ore deposit amount that enters Hhigh-efficient thickener, reduces dry ore deposit amount 60～80%, reduces the consumption 30～50% of Hhigh-efficient thickener flocculant; In addition, the overflow water of Hhigh-efficient thickener is connected with the ring water supply system, because overflow water water quality is down to below 100ppm by 300ppm, can improves ring clarification of water degree, meet the requirement of flotation operation to water quality.
