Abstract
The utility model provides a leaching tank, and relates to improvement of a structure of a leaching tank stirring device in an air-entrapping leaching process during wet metallurgy. The leaching tank is characterized in that a stirrer on a stirring shaft is arranged on the middle lower part of the stirring shaft. The leaching tank structurally comprises an upper stirring device which is a spiral stirring paddle and lower stirring devices which are disk turbine stirring paddles. The leaching tank has the following beneficial effects: two layers of stirring devices are installed on the stirring shaft, so the axial circulation capacity and the shear dispersion capacity are enhanced, the stirring effect is good, the material dissolution rate is high and the solid, liquid and gas are mixed uniformly, thus improving the reaction rate, the metal leaching rate and the effective utilization rate of the gas.
Description
Technical field
A kind of leaching vat relate to the improvement of the leaching vat whipping appts structure that a kind of aerating leaching process of hydrometallurgy uses.
Background technology
At present, often to use the aerating extract technology at hydrometallurgy process.For example, processing the complicated nickel materials processes such as nickel cobalt sulfide, nickelous carbonate, nickel hydroxide, the main method of employing is that material is carried out chlorine leaching, and the nickel chloride solution with output send the nickel system to produce the electrolytic nickel product again.Its chlorine leaching process adopts vertical mechanical stirring-type leaching vat mostly, and stirring capacity is strong, and suitable chlorine soaks production technique, but also comes with some shortcomings.
The vertical mechanical stirring-type leaches the whipping appts of drill traverse, usually is comprised of the drive unit, the stir shaft that vertical center penetrates cell body and agitating vane or the stirring arm that is positioned on the stir shaft that are positioned at the leaching vat upper end.Often can cause the dissolution rate of solid materials also undesirable because mixing effect is poor in process of production, it is little that solid-liquid-the gas three-phase mixes poor probability of collision, affected the effective rate of utilization of chlorination reaction speed, metal leaching rate and chlorine.
Summary of the invention
The deficiency that the purpose of this utility model is just changed places above-mentioned prior art is existed provides that a kind of mixing effect is good, dissolution rate is fast, and solid-liquid-gas three-phase mixes, and speed of reaction is fast, the high leaching vat of effective rate of utilization of metal leaching rate and chlorine gas.
The purpose of this utility model is achieved through the following technical solutions.
A kind of leaching vat, its structure comprises: leach cell body, stir shaft and be positioned at agitator on the stir shaft, be positioned at leaching vat body sidewall top drainage conduit, be positioned at the feed-pipe feed that leaches cell body middle and lower part sidewall, be positioned at the chlorine access tube and the scum pipe that leach the cell body bottom, it is characterized in that the agitator on its stir shaft is positioned at the middle and lower part of stir shaft, this agitator comprises up and down two-layer whipping appts.
A kind of leaching vat of the present utility model is characterized in that it is the screw mixing oar that device is stirred on described upper strata.
A kind of leaching vat of the present utility model is characterized in that it is disc turbine formula stirring rake that device stirs in described lower floor.
A kind of leaching vat of the present utility model, it is relative with the leaching vat charging mouth of pipe to it is characterized in that the mid-way of the short transverse between device and lower floor whipping appts is stirred on its upper strata.
A kind of leaching vat of the present utility model, two-layer whipping appts has been installed on the stir shaft, has been strengthened the axial circulation ability and sheared dispersive ability, mixing effect is good, material dissolution speed is fast, solid-liquid-gas three-phase mixes, and improved the effective rate of utilization of speed of reaction, the gentle gas of metal leaching rate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of leaching vat, its structure comprises: leach cell body 1, stir shaft 2 and be positioned at agitator on the stir shaft, be positioned at leaching vat body sidewall top drainage conduit 3, be positioned at the feed-pipe feed 4 that leaches cell body middle and lower part sidewall, be positioned at the chlorine access tube 5 and the scum pipe 6 that leach the cell body bottom, agitator on its stir shaft is positioned at the middle and lower part of stir shaft, its structure comprises: for stirring device 7 in the upper strata of screw mixing oar, lower floor is lower floor's whipping appts 8 of disc turbine formula stirring rake.It is relative with the leaching vat charging mouth of pipe that the mid-way of the short transverse between device and lower floor whipping appts is stirred on its upper strata.
Embodiment
The leaching vat specifications and models are Φ 2200 * 3200mm, and length-to-diameter ratio is 1.45:1, and stir shaft is the titanium axle, axial length 3.36m, the diameter of axle is 95mm, and two-layer whipping appts is installed on the stir shaft, it is the screw mixing oar that device is stirred on the upper strata, and lower floor's whipping appts is disc turbine formula stirring rake.The material that enters by the leaching vat charging mouth of pipe enters the position between upper strata whipping appts and the lower floor's whipping appts, strengthen the axial circulation ability and sheared dispersive ability, accelerated the impact of collision between the material solid particulate and liquid stream, break the balance of particle diameter liquid film concentration, improve the dissolution rate of solid particulate, accelerated the carrying out of Leaching reaction.
