Abstract
The utility model provides a leaching tank, and relates to improvement of a structure of a leaching tank in an air-entrapping leaching process during wet metallurgy. The leaching tank structurally comprises a leaching tank body, a stirrer device, a feed pipe, a discharge pipe, a vent pipe and a slagging pipe and is characterized in that a stirring shaft of the stirrer device is arranged deviating from the normal axis of the leaching tank. The chlorine leaching tank has the following beneficial effects: the stirring shaft of the stirrer device is arranged deviating from the normal axis of the chlorine leaching tank; the radial force and radial flow speed of the leached slurry are enhanced and changed and the probability and speed of solid-liquid-gas mixture collision are increased through eccentric stirring; as eccentric stirring has a turbulence effect, flow baffles are not required to be installed on the inner walls of the leaching tank, a solution can not be cut off in the radial direction in the stirring process and the rapid proliferation and reaction absorption of gas and ore pulp are enhanced, so that the effective utilization rate and leaching reaction efficiency of the gas are improved.
Description
Technical field
A kind of leaching vat relate to the texture improvement of the leaching vat 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.Because hanging down, stir shaft and leaching vat cell body axis close, agitating vane or stirring arm stir in the cell body central position, the action of turbulent flow that stirs is poor, phenomenon can occur radially to stop, to solve by at the leaching vat inwall flow-stopping plate being installed, the effect that stirs, the dissolution rate of solid materials are also undesirable, and 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 chlorination reaction speed is fast, the high leaching vat of effective rate of utilization of metal leaching rate and gas.
The purpose of this utility model is achieved through the following technical solutions.
A kind of leaching vat, its structure comprise leaching cell body, agitator unit, feed-pipe, drainage conduit, ventpipe and scum pipe, it is characterized in that the stir shaft of agitator unit departs from the vertical axis setting of leaching vat.
A kind of leaching vat of the present utility model, the distance that it is characterized in that described stir shaft medullary ray and leaching vat central axis is 1/5th of leaching vat diameter, for off-centre stirs.
A kind of leaching vat of the present utility model, the stir shaft of agitator unit depart from the vertical axis setting of chlorine leaching groove, and eccentric the stirring strengthens and changed the radial force of leaching slurry and flow velocity radially, increased solid-liquid-gas three-phase and mixed probability and the speed of colliding.Because eccentric the stirring has action of turbulent flow, the leaching vat inwall need not to install flow-stopping plate, and solution stream radially can not stop in the whipping process, strengthens rapid diffusion and the reactive absorption of gas and ore pulp, has improved effective rate of utilization and the Leaching reaction efficient of gas.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of leaching vat, its structure comprise leaching cell body 1, agitator unit 2, feed-pipe 3, drainage conduit 4, ventpipe 5 and scum pipe 6, it is characterized in that the stir shaft 7 of agitator unit departs from the vertical axis setting of chlorine leaching groove; The distance of described stir shaft medullary ray and leaching vat central axis is 1/5th of leaching vat diameter, for off-centre stirs.
Embodiment
The leaching vat specifications and models are Φ 2200 * 3200mm, length-to-diameter ratio is 1.45:1, by cell body, whipping appts, chlorine adding apparatus, advance, drainage conduit forms, the leaching vat whipping appts is installed in a side of leaching vat, the distance of stir shaft medullary ray and leaching vat central axis is 1/5th of leaching vat diameter, for off-centre stirs.The eccentric stirring strengthens and changed the radial force of leaching slurry and flow velocity radially, increased solid-liquid-gas three-phase and mixed probability and the speed of colliding, and improved diffusion and the Average Air Content of chlorine.
