Description
Technical field
This utility model relates to mining equiment field, the stirring system of a kind of flotation device.
Background technology
Flotation is the sorting technology grown up for 19 end of the centurys, and oneself has the history of more than 100 year so far, and its development is very
Rapidly.Method for floating has become one of topmost method sorting raw mineral materials in the world, and it is applied not only to sort metal
Mineral and nonmetallic mineral, the many being also widely used in the industries such as metallurgy, papermaking, agricultural, food, medicine, microorganism, environmental protection is former
Material, product or the recovery of garbage, separate, purification etc..At a rough estimate, in the world the recovery of Non-ferrous minerals about 90% with
On be to use floatation, and also occupy about 50% in ferrous metal mineral field.Flotation device is most important in mineral manufacture field
One of sorting equipment.Mechanical agitation pneumatic flotation cell is to realize the most widely used physical means of sorting mineral, mainly applies
In industries such as mining industry, coal, water process, non-ferrous metal, papermaking.During flotation, ore pulp sends into flotation device after being in harmonious proportion with floating agent,
Stir ore pulp through Mechanical Driven impeller, and the air of entrance is dispersed into minute bubbles so that target minreal is attached to bubble formation
Mineral laden bubble, floats to mineral surfaces and forms froth bed, and foam scrapes or by discharging by the way of overflowing through scraper plate, has both obtained foam
Product, rather than froth pulp is then discharged with the low stream of ore pulp.The quality of flotation technology economic indicator, close with the flotation device performance selected
Cut is closed.
The working media of flotation device is gas, solid-liquid three-phase fluid-mixing, and its internal flow is extremely complex, the difficulty of research work
Spend the biggest.Research to flotation device interior flow field at present is mainly based upon water medium, the method using measuring, this side
Although method is directly perceived, convenient, but can only be measured water medium, cannot be carried out surveying to the three-phase fluid-mixing of gas, solid-liquid
Fixed.Additionally, flotation device is primarily present liquid level magic flower, ore pulp short circuit in actual motion, froth bed thickness is unstable, and mineral return
The problems such as yield is relatively low.Flowing law within flotation device is not the most grasped, especially by the existence explanation people of these problems
Insufficient to the understanding of internal gas, solid-liquid three-phase flow field, so from improving flotation device stir system design, reducing flotation device operation
Management cost and save energy angle and say, improves the stirring efficiency of flotation device, to improve its reliability of operation be the most necessary,

The impeller of machine and the composite construction of stator be Uniting and with the use of one group of component, be most important in each parts of flotation device
Main component.Ore pulp is through between the intake impeller lower blade of impeller lower blade inner edge, meanwhile, outside and the low-pressure air fed
Entered between impeller lower blade by the aperture of air distributor periphery.Ore pulp and air are sufficiently mixed between impeller lower blade
After, impeller lower blade outer rim discharge.And stator being thrown away the direction of motion of ore pulp from tangentially becoming axial by impeller, makes impeller
Ore pulp Xu Su around spreads apart, and to ensure that at impeller outlet, ore pulp is maximum with the relative velocity of blade end, thus promotes and fills
Gas and mixing effect, form more stable froth zone.During flotation device operating, need to produce stronger pump by rotating of impeller
Energy-absorbing power and strong turbulent flow stirring, thus form circulation, increase target minreal mineralising probability.Along with the increase of mine capacity,
Flotation device develops to maximization direction, and this necessarily causes the load of flotation device and agitated flow to increase therewith, therefore, improves
Service life of flotation device stirring system, to reduce its power consumption particularly important.Impeller that at present both at home and abroad mine floatation machine uses and
Stator rim is all linear, though this form impeller and stator processing are simple, but is easier to abrasion, mixing effect and dispersion effect
The most undesirable, liquid level magic flower etc. easily occurs, and energy consumption is higher, directly affect floatation indicators, restriction production.
