Abstract
The utility model provides a leaching tank, and relates to improvement of a structure of a leaching tank feeding device in an air-entrapping leaching process during wet metallurgy. The leaching tank structurally comprises a leaching tank body, a stirring shaft, stirring vanes, a discharge pipe, a vent pipe and a slagging pipe, wherein the stirring vanes are arranged on the middle lower part of the stirring shaft; the discharge pipe is arranged on the upper part of the side wall of the leaching tank body; and the vent pipe and the slagging pipe are arranged at the bottom of the leaching tank body. The leaching tank is characterized in that a feed pipe of the leaching tank horizontally penetrates through the middle lower side wall of the leaching tank; and the discharge hole of a discharge end nozzle of the feed pipe is opposite to the part between the stirring vanes. The leaching tank has the following beneficial effects: the leaching tank can be used for effectively increasing the material feeding depth; and the entering slurry is timely contacted with the vanes of the stirring device to increase collision between the solid grains and impact of liquid flow and break the balance of the grain-size liquid film concentration, thus improving the dissolution rate of the solid grains and accelerating the leaching reaction.
Description
Technical field
A kind of leaching vat relate to the improvement of the leaching vat feeding device structure that a kind of aerating leaching process of hydrometallurgy uses.
Background technology
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.
At present, the feeding device of vertical mechanical stirring-type leaching vat is generally the feed siphunculus that vertical mechanical stirring-type leaching vat top cover vertically penetrates, and the outlet of supply pipe is positioned at leaching vat inner chamber middle and upper part.Because the material after the pulp that enters is given the top with agitator, there is part mineral solids particle to have neither part nor lot in reaction and just discharges from the discharge port on cell body top with material stream, had a strong impact on leaching effect.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists for above-mentioned prior art, providing a kind of can effectively increase material and feed the degree of depth, the impact of the collision between the increase solid particulate and liquid stream, break the balance of particle diameter liquid film concentration, improve the dissolution rate of solid particulate, accelerated the leaching vat that Leaching reaction carries out.
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 the stir shaft middle and lower part agitating vane, be positioned at leaching vat body sidewall top drainage conduit, be positioned at the ventpipe and the scum pipe that leach the cell body bottom, it is characterized in that the feed-pipe level of leaching vat penetrates the middle and lower part sidewall of leaching vat, the jet hole of feed-pipe discharge end is relative with the agitating vane middle part.
A kind of leaching vat of the present utility model is characterized in that its agitating vane that is positioned at the stir shaft middle and lower part is two-layer, and the jet hole of its feed-pipe discharge end is relative with the middle part of agitating vane.
A kind of leaching vat of the present utility model, effectively increase material and fed the degree of depth, the slip that enters in time contacts with the blade of whipping appts, the impact of the collision between the increase 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.
Description of drawings
Fig. 1 is the structural representation of utility model.
Embodiment
A kind of leaching vat, its structure comprises: leach cell body 1, stir shaft 2 and be positioned at agitating vane 3 on the stir shaft, be positioned at leaching vat body sidewall top drainage conduit 4, be positioned at the ventpipe 5 and the scum pipe 6 that leach the cell body bottom, the feed-pipe 7 of leaching vat is arranged on the middle and lower part sidewall of leaching vat, its feed-pipe is arranged on the middle and lower part sidewall of leaching vat, and design and installation feed nozzle, it is relative that the position of its nozzle discharge hole is positioned at the middle part of two-layer agitating vane.
During operation, material is advanced by the feed-pipe of the leaching vat on the middle and lower part sidewall that is arranged at leaching vat, and its feed inlet end is positioned at the whipping appts middle part relatively; Its feed-pipe port is located along the outer that extends near the whipping appts blade in the leaching vat groove, the slip that enters is contacted with agitating vane is instantaneous, increased the impact of collision between the 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.
Claims (2)
1. leaching vat, its structure comprises: leach cell body, stir shaft and be positioned at the stir shaft middle and lower part agitating vane, be positioned at leaching vat body sidewall top drainage conduit, be positioned at the ventpipe and the scum pipe that leach the cell body bottom, it is characterized in that the feed-pipe level of leaching vat penetrates the middle and lower part sidewall of leaching vat, the jet hole of feed-pipe discharge end is relative with the agitating vane middle part.
2. a kind of leaching vat according to claim 1 is characterized in that its agitating vane that is positioned at the stir shaft middle and lower part is two-layer, and the jet hole of its feed-pipe discharge end is relative with the middle part of agitating vane.
