Abstract
The invention relates to a treatment system for a concentration tank of iron ore concentrates. The treatment system comprises the concentration tank, a concentration tank overflow tank, a central distribution barrel and ore concentrate pipelines, wherein output ports of the ore concentrate pipelines are connected with the central distribution barrel; the concentration tank is arranged at the outer side of the central distribution barrel; the concentration tank overflow tank is arranged at the outer side of the concentration tank; the ore concentrate pipelines are composed of a plurality of thin ore concentrate pipelines and a plurality of thick ore concentrate pipelines; the plurality of thin ore concentrate pipelines are communicated with the plurality of thick ore concentrate pipelines through a fed ore distribution box; the number of the thin ore concentrate pipelines is larger than that of the thick ore concentrate pipelines; and one ends of the thick ore concentrate pipelines are connected with the central distribution barrel, and the other ends of the thick ore concentrate pipelines are connected with the fed ore distribution box. The ore concentrate pipelines are composed of the thin ore concentrate pipelines and the thick ore concentrate pipelines, so that the ore feeding flow rate is reduced to ensure that the content of solid particles in overflow water cannot exceed the standard under the condition that the concentration tank operates over a design, and furthermore, the treatment capacity of the concentration tank is enhanced, and the content of the solid particles in the overflow water is reduced.
Description
Technical field
The present invention relates to a kind of iron ore concentrate concentration basin treatment system.
Background technology
Yunnan 22 meters concentration basins of big Red Hill pipeline advance ore deposit concentration 20% to 30% ore removal concentration 65% to 70%; Built in 2006 be 4,000,000 tons adopt, one of the conveyance system of choosing, pipeline, the design treating capacity is 2,300,000 tons/year, day output is 7200 tons, the solids in the overflow water≤200 mg/litre.The big Red Hill pipeline in Yunnan carry from January 1st, 2007 begin to 2009 three in the period of, conveying capacity in 2007 is that 111.6 ten thousand tons, 2007 conveying capacities are that 185.1 ten thousand tons, 2008 conveying capacities are 2,260,000 tons, all in the scope of 2,300,000 tons of design conveying capacities, the solids in the overflow water of concentration basin is below 200 mg/litre.
Along with the continuous development of Kunming iron and steel group company, big Red Hill mining company has carried out improving to beneficiation flowsheet has increased many corollary equipments, and concentrate output is significantly risen.Pipeline run reached 2,460,000 tons in 2010, and wherein the first quarter, conveying capacity reached 10,000 tons, and (selecting factory's maintenance deduction) average daily throughput reaches 8258 tons, super designed capacity 14.6%.The concentration basin overflow water run to mix phenomenon to begin to highlight, and selects factory to come the ore deposit amount unbalanced in addition, measures to surpass 8258 tons when big, and the concentration basin overflow water runs that to mix the imagination more serious.Since in the May, 2011, selected factory to strengthen concentrate output, 22 meters concentration basin day outputs reach 8904 tons, super design 23.3%.Overflow water runs mixed phenomenon and is on the rise, and after testing: solids reaches 1.2 grams per liters in the overflow water, exceeds standard more than 20 times.
As shown in Figure 1, have respectively that pipe selects the ore pulp of the 20%-30% of factory concentration to enter 22 meters concentration basins difference under three concentrate; 300 tons of elected factory iron ore concentrate treating capacities/time; 25% mineral slurry flux 960m
3/ h; Flow velocity 3.77 meter per seconds; 22 meters concentration basin treating capacities in scope of design, overflow water solid content≤200 mg/litre; It is normal range of operation; Elected factory iron ore concentrate treating capacity bring up to 370 tons/time; 25% mineral slurry flux 1188m
3/ h; Flow velocity 4.67 meter per seconds; 22 meters super scopes of design 23.3% of concentration basin treating capacity, overflow water solid content 〉=2 grams per liters; Exceed more than 20 times of normal range of operation; A large amount of iron ore concentrates run off to cause than large economy and lose.
Summary of the invention
The present invention has designed a kind of iron ore concentrate concentration basin treatment system, the technical problem of its solution be existing iron ore concentrate concentration basin treatment system since down the increasing of ore deposit amount cause the solid content in the overflow water to exceed standard, make concentration basin disposal ability deficiency.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of iron ore concentrate concentration basin treatment system, comprise concentration basin (1), concentration basin overflow launder (2), central dispense bucket (3) and concentrate pipeline (4), concentrate pipeline (4) delivery outlet is connected with central dispense bucket (3), central dispense bucket (3) outside is concentration basin (1), concentration basin (1) outside is concentration basin overflow launder (2), it is characterized in that: described concentrate pipeline (4) is made up of many concentrate tubule roads and Duo Gen concentrate extra heavy pipe road, many concentrate tubule roads and Duo Gen concentrate extra heavy pipe road are communicated with by advancing ore deposit distributor box (5), concentrate tubule road quantity is more than concentrate extra heavy pipe road quantity, one end in concentrate extra heavy pipe road is connected with central dispense bucket (3), the other end in concentrate extra heavy pipe road with advance ore deposit distributor box (5) and be connected.
Further, be respectively equipped with a control valve (6) in every concentrate extra heavy pipe road.
Further, central dispense bucket (3) forms concentric structure with concentration basin (1).
Further, concentration basin overflow launder (2) forms concentric structure with concentration basin (1).
This iron ore concentrate concentration basin treatment system is compared with existing iron ore concentrate concentration basin treatment system, has following beneficial effect:
(1) the present invention is because by being related to the concentrate pipeline in concentrate tubule road and concentrate extra heavy pipe road, give the ore deposit flow velocity to guarantee that solid content can not exceed standard in the super design and operation situation of the concentration basin underflow flowing water thereby reduce, thereby improved the disposal ability of concentration basin, reduced solid content in the overflow water.
(2) iron ore concentrate concentration basin treatment system of the present invention also guarantees that by the dischargeable capacity that strengthens 2 concentration basins solid content can not exceed standard in the overflow water, thereby has improved the disposal ability of concentration basin, reduces solid content in the overflow water.
