The transversal wash tub pipe [8] is in pipe spiral shape. This equipment breaks through the traditional theoretic limit that the ratio of height to diameter can not less than 0.45, and adopts the ultra-limit ratio of height to diameter that h/d = 0.33-0.40; thus the sulfuric acid residual separating-purifying-sorting apparatus has the advantages of simple operation, low energy consumption, high recovery rate, low cost, stable running and without generating secondary pollution, etc. The sulfuric acid residual separating-purifying-sorting apparatus can also be widely used for resources processing of lower grade tailings, metalliferous solid slag, low-density non-metal materials, metal mine debris and chemical fine materials.
Description
One, technical field
The utility model belongs to recycling treatment equipment.Relate in particular to a kind of sulfate slag and separate the screening installation of purifying.
Two, background technology
Abroad to the existing last 100 years history of the utilization of sulfate slag,, up to the present, the treatment technology of sulfate slag be there is no important breakthrough though some industrially developed country were not interrupted the research to sulfate slag.Its reason mainly is due to complex manufacturing, process control difficulty, product index shakiness and the problem such as utilization rate is on the low side, operating cost is crossed height.Trace it to its cause, equipment is the principal element of restriction sulfate slag resource development.Because the long-term Special Equipment that does not have at sulfuric-acid residue sorting, normally with different sorting process, carry out sorting by original legacy equipment, though these technologies and equipment to a certain extent can the sorting sulfate slags, but and the sorting characteristics of not exclusively suitable sulfate slag, its result causes the efficiency of separation low, the product quality shakiness, and problems such as the too high and complex technical process of operating cost occur.
Be most commonly used to the conventional helical chute (Qiu Jicun, mineral dressing, metallurgical industry publishing house, 1987 Beijing) of sulfuric-acid residue sorting, its effect is that the purpose mineral are carried out preliminary enrichment, under go on foot sorting process rough concentrate be provided.For the consideration to factors such as material density and recovery granularity lower limits, generally between 0.45～0.8, lower limit is no more than 0.45, gets 0.5～0.6 times usually in this equipment pitch to diameter ratio h/D variation.Can guarantee like this that grain graininess is thick, the bigger mineral of density contrast obtain continuous sorting in the more turbulent flow film and the rheology field of force between purpose mineral and the non-purpose ore deposit, and unlikely " heap slide " and " drawing slide ".But when this legacy equipment is used for sulfuric-acid residue sorting, because purpose mineral (iron-bearing mineral) in the sulfate slag and the density contrast minimum (being generally between the 0.1-0.2%) between the non-purpose mineral (gangue minerals such as residual sulfur-donor, troilite intergrowth and silica), under this little density contrast, when the ratio of chute pitch h and chute diameter D was 0.45～0.8 this conventional pitch to diameter ratio, sulfate slag can't effectively separate.At this moment, purpose mineral in the sulfate slag and non-purpose mineral are mixed mutually in the rheology field of force of screw fluid and are thrown toward the chute outside, finally become mine tailing.
Three, the summary of the invention the purpose of this utility model provide a kind of simple to operate, energy consumption is low, the rate of recovery is high, cost is low, stable, the sulfate slag that do not produce secondary pollution separates the purification screening installation.This equipment also can be widely used in recycling treatment such as the sorting purification, concentration and separation of other low-grade tailings, containing metal solid slag, low density non-metallic material, metal mine mine tailing and chemical industry superfine material, comprehensive recovery.
For achieving the above object, technical solution adopted in the utility model is: mine distributor is fixedlyed connected with feed launder and be installed on the upper bracket, upper bracket is fixedlyed connected with the helicla flute pillar, spiral chute is fixedlyed connected with the helicla flute pillar, the upper end of spiral chute is positioned under the upper bracket, lower end and mine cut groove join, mine cut groove with connect ore bucket and be connected, be provided with horizontal wash tub pipe in the inboard of spiral chute.
The horizontal external high-pressure water of wash tub pipe, the inboard has some apopores, and it is shaped as the tubular type helical form.Spiral chute is 1～4.The high h of the flight of spiral chute with the ratio of outer diameter D is: h/D=0.33～0.40.Spiral chute is to be made by fiberglass reinforced plastics or fiberglass, and liner is the corundum type high-abrasive material.
Owing to adopt technique scheme, the utility model has been broken through pitch to diameter ratio can not adopt the ultralimit pitch to diameter ratio design of h/D=0.33～0.40 less than 0.45 the traditional theory limit, makes it to have simple to operate, distinguishing features such as energy consumption is low, rate of recovery height; After increasing the helicla flute diameter, still can effectively reclaim fine-particle minerals; Improved the efficiency of separation of little density contrast sulfate slag.Increase the design of horizontal flushing water, do not produced secondary pollution, improved the unit concentration ratio.
The utility model not only is suitable for the processing of sulfate slag, also can be widely used in the recycling treatment of other low-grade tailings, containing metal solid slag, low density non-metallic material, metal mine mine tailing and chemical industry superfine material.
