Description
Technical field
The present invention relates to a kind of air stirring slots to belong to metallurgy and set more particularly to a kind of multi-stage booster Gas Stirring slot
Standby technical field.
Background technique
Leaching is the routine techniques of valuable metal hydrometallurgy.Leaching is solid, liquid two-phase, even solid, liquid, gas three-phases
Heterogeneous reaction process.The process is carried out in the surface of solids, is influenced by Ion transfer diffusion.With regard to liquid, solid leaching process and
Say that it has main steps that: (1) leaching agent is inwardly spread by the crack of ore particle；(2) in ore particle reflecting point chemical reaction；(3)
Oneself diffuses into solution by the substance of dissolution outward.It is clear that in order to accelerate leaching process, the leaching of levigate material has
Great advantage increases the effective surface area of ore particle because material is levigate, obtains biggish respond；Decrease diffusion
Thickness degree, increases diffusion coefficient；It prevents ore particle to settle, accelerates the liquid renewal speed on ore particle surface.
Conventional stirring equipment mainly has mechanical stirring and two kinds of magnetic agitation.(1) conventional mechanical stirs.Existing normal pressure stirs
Mixing leaching equipment is mostly open type suitable for reading or semi-enclosed structure, and mixing plant is usually acidproof Teflon stir paddle；
First pernicious gas, acid mist for generating in leaching process etc. not only pollute environment but also corrode equipment, to operative employee from evolution suitable for reading
People will also result in biggish actual bodily harm；Second different working media paddle blades not easy cleaning, replacement are replaced, a leaching is caused
Equipment can only special purpose.In addition, heavy mineral are easily enriched in trough bottom, round especially in enterprise production process,
Rectangular, a kind of reaction vessel of taper, if circular reaction vessel is in mechanical agitation process, the central area of stirring and border area
There is very big difference, is inserted into blender in center, forms high speed vortex in high-speed agitating process, and in leaching of ores mistake
Journey Minerals specific gravity is larger, and under the effect of centrifugation, most mineral are enriched to circular reactor in whipping process
It bottom and is simply attached on reactor wall, and is in stacking states, realize that mineral grain uniformly divides in the solution with expected stir
Scattered purpose is completely different, and to a certain extent if mixing speed is not strong enough, mineral grain does not turn with the solution of mixing direction
Dynamic direction moves at the same speed, or even slowly movement, bulk deposition cause metal leaching rate low；For rectangular or have the reactions of corner angle
Container, in addition to circular reaction vessel there are the problem of other than, whipping process chats composition granule can largely edges and corners accumulate, shape
At the dead angle of stirring；Similarly for the reaction vessel of taper, meeting while mineral grain is attached to reaction wall under the effect of gravity
The reaction dead angle that conical vessel base angle is fallen under a large amount of, is not achieved the purpose of uniform stirring.It is most in terms of mechanical stirring
Blender have very high selectivity to reaction vessel, indirectly limit the scope of application of blender.(2) conventional magnetic stirs
It mixes.The basic principle is that being pushed using magnetic field using the magnetic field principle that identical charges repel each other, there is a natural attraction between the sexes and placing band magnetic in a reservoir
Property stirrer carry out circumferential running, thus achieve the purpose that stir liquid.Magnetic agitation is selectively extremely strong to mineral and stirs
Unevenly, whether such as reaction vessel bottom flat, position whether just, with used voltage whether between 220V ± 10V the problems such as
Stirrer can be caused to beat or do not stir in stirring.In addition, magnetic agitation can not work for a long time, under normal circumstances,
Middling speed operating can be continuous work 8 hours, and running at high speed can be continuous work 4 hour, and strenuous vibration may occur when work.In magnetic
In power whipping process, the generation of the above problems is undoubtedly an important factor for influencing leaching efficiency.With mechanical stirring mode phase
It is to promote stirring rotator to operate by magnetism than the characteristics of, magnetic agitation, essence is similar with mechanical stirring, but magnetic agitation
Intensity is often strong without mechanical stirring, i.e., for the container for handling big volume when there are certain restrictions, in addition, because magnetic force stirs
For the stirring rotator mixed with magnetism, therefore when mineral higher with a kind of iron content of magnetism for processing, magnetic mineral is a large amount of
It is wrapped in above stirrer, causes resistance to the operating of rotor, under conditions of magnetic drive force is weaker, be not enough to drive a large amount of
The rotor of mineral package effectively causes the problems such as stirring is uneven, stirring is failed, directly reduction metal leaching efficiency.
Partial metallurgical equipment is not suitable for the equipment such as mechanical stirring, magnetic agitation, so that air stirring is used, in addition, part
Reaction needs oxygen atmosphere, and air stirring is conducive to increase kinetics.Therefore, develop high degree of automation, structure it is simple,
The mixing plant highly reliable, failure rate is low is promoted to enhanced leaching kinetics and leaches agitating device application surface with weight
The meaning wanted.
