Description

A kind of strength leaching vat
Technical field:
The utility model relates to a kind of leaching vat, belongs to the gold cyanidation technology and extracts gold and silver, or be used for the equipment that non-ferrous metal mineral hydrometallurgy leaches operation.
Background technology:
Leaching vat are one of major equipments of gold cyanidation technology extraction gold and silver, and the mineral after the fine grinding through inflation, stirring, make the gold and silver dissolving in the mineral in cyanide solution.At present, mostly the leaching plant that extensively adopts is the mechanical agitation type leaching vat both at home and abroad, in order to satisfy the needed oxygen of gold and silver solubilizing reaction, constantly charge into air in ore pulp when stirring.In order to guarantee the dissolution rate of gold in the mineral grain, must have certain stirring intensity for ore pulp.Like this, the one, mineral grain is better suspended in ore pulp, guarantee the pulp density unanimity in the leaching vat; The 2nd, increase the contact probability of mineral grain and medicament, air, and improve medicament, oxygen velocity of diffusion to mineral surface, the while also improve mineral surface the dissolved gold ion to the velocity of diffusion of solution inside.Therefore, leaching vat should have certain stirring intensity and provide requisite oxygen tolerance two functions.At present, the mechanical agitation type leaching vat that adopt were furnished with air charging apparatus simultaneously during gold cyaniding was both at home and abroad produced.Mechanical stirring is to provide necessary stirring intensity to ore pulp, and inflation is to dissolve needed oxygen in order to satisfy gold and silver, and both are indispensable.In actual production, the proportion that has changed local ore pulp that charges into owing to air, the ore pulp bubble mixture that forms produces the power that moves upward, this can alleviate churned mechanically power consumption originally, but it is opposite because of the mechanical stirring direction on the contrary with ore pulp bubble mixture direction of motion, increased churned mechanically power consumption on the contrary, allowed a large amount of power wastees among formation ore pulp eddy current and mechanical wear.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of equipment manufacturing cost low, and manufacturing process is simple, and power consumption is low, is difficult in the operational process running groove, and is reliable, the strength leaching vat that maintenance capacity is few.
The purpose of this utility model can reach by following measure: a kind of strength leaching vat, it has cell body, connect circulating barrel in the cell body, the bottom of circulating barrel connects gas distributor, gas distributor connects the gas automatic control device by loading line, the upper end connective slot lid of cell body, cell body is provided with mineral-feeding pipe, ore discharge pipe, manhole and bottom blowing device.
For further realizing the purpose of this utility model, the length-to-diameter ratio of described cell body is 3-4: 1.
For further realizing the purpose of this utility model, the bottom of described cell body is tapered, and the base cone angle is at 45 ℃-60 ℃.
For further realizing the purpose of this utility model, described gas distributor is an annular, and the bottom is not sealed for opening wide shape, and annular distribution has aeration aperture on the gas distributor.
For further realizing the purpose of this utility model, described aeration aperture is the square opening of offering to the center, and the slot length range is 1-500mm, width range 1-20mm.
For further realizing the purpose of this utility model being evenly distributed with baffle plate in the described cell body, baffle plate connects circulating barrel by bracing frame.
For further realizing the purpose of this utility model, the plane is lower than ore discharge pipe 0-3.0m on the described circulating barrel.
For further realizing the purpose of this utility model, described gas automatic control device is connected and composed by gas meter, variable valve, control unit.
For further realizing the purpose of this utility model, described bottom blowing device is connected and composed by bottom blowing pipeline, check valve and preventing clogging up device.
The utility model can produce following positively effect compared with the prior art: the utility model is mainly used in gold cyanidation technology gold (silver) and leaches (dissolving) from raw mineral materials.Be to utilize to charge into stirring, the solvency action of air in ore pulp, make ore pulp in groove, move, circulate, allow mineral grain, medicament, air in ore pulp, fully contact, be beneficial to the dissolving of gold.The utility model ore pulp round-robin power is air, it or not the mechanical power that impeller etc. produces, its utilization charges into the power that air produces ore pulp is stirred, and provide mineral to react needed oxygen simultaneously, not only energy-conservation but also fine leaching effect is arranged, it does not have mechanical operating part, and equipment manufacturing cost is low, manufacturing process is simple, and facility investment is low; Power consumption is low; Be difficult for running groove in the operational process; Reliable, maintenance capacity is few.
Description of drawings:
Accompanying drawing is the structural representation of utility model.
Embodiment:
Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:
Embodiment: a kind of strength leaching vat (referring to accompanying drawing), it has cell body 1, the length-to-diameter ratio of cell body 1 (length: diameter) be 3-4: 1, the bottom of cell body 1 can be square as required also can be tapered, and the base cone angle is at 45 ℃-60 ℃ when tapered.Be evenly distributed with 3 baffle plates 11 in the cell body 1, baffle plate 11 connects circulating barrel 2 by bracing frame 12, and cell body 1 is 1 with the diameter ratio of circulating barrel 2: 0.25-0.5; The length ratio is 1: 0.6-0.9.The bottom of circulating barrel 2 connects gas distributor 3, and gas distributor 3 is annular, and the bottom is for opening wide shape, do not seal, annular distribution has aeration aperture on the gas distributor 3, the square opening of aeration aperture for offering to the center, the slot length range is 1-500mm, width range 1-20mm.Gas distributor 3 connects gas automatic control device 4 by loading line 5, gas automatic control device 4 by gas meter, manually or the Controlling System formed of pneumatic automatically or motor-driven control valve, control unit, can carry out flow control automatically to the air that charges into.The upper end connective slot lid 7 of cell body 1, groove lid 7 is used for sealing cell body 1, satisfies environmental requirement and serves as service platform.The top of cell body 1 is provided with mineral-feeding pipe 8, ore discharge pipe 9, the bottom of cell body 1 is provided with manhole 6 and bottom blowing device 10, manhole 6 is used for personnel and enters internal overhaul, bottom blowing device 10 restarts circulation when being used for deep gouge, its bottom blowing pipeline is provided with check valve and preventing clogging up device, and it is to be power by the high-pressure air or the high pressure water that feed, opens check valve and preventing clogging up device, the mineral that are deposited in bottom land are blown open, circulation is proceeded.
