Description
Technical field
The present invention relates to field of mining equipment, specially a kind of stirring system of flotation device.
Background technology
Flotation is the sorting technology grown up in 19 end of the centurys, and oneself has the history of more than 100 years so far, and it develops very
Rapidly.Method for floating turns into sorts one of topmost method of raw mineral materials in the world, and it is applied not only to sort metal
Mineral and nonmetallic mineral, are also widely used in the industries such as metallurgy, papermaking, agricultural, food, medicine, microorganism, environmental protection
Many raw materials, the recovery of product or discarded object, separation, purification etc..At a rough estimate, time of Non-ferrous minerals in the world
About 90% is received above is using floatation, and also occupy about 50% in ferrous metal mineral field.Flotation device is mineral processing neck
One of most important sorting equipment in domain.Mechanical agitation pneumatic flotation cell is to realize the most widely used physical means of sorting mineral,
It is mainly used in the industries such as mining industry, coal, water process, non-ferrous metal, papermaking.During flotation, ore pulp reconciles with floating agent
After send into flotation device, stir ore pulp through Mechanical Driven impeller, and the air of entrance be dispersed into minute bubbles so that target minreal
Bubble formation mineral laden bubble is attached to, mineral surfaces formation froth bed is floated to, foam is scraped through scraper plate or by certainly excessive side
Formula is discharged, and both obtains froth pulp, rather than froth pulp is then discharged with the low stream of ore pulp.The quality of flotation technology economic indicator, with
The flotation device performance of selection is closely related.
The working media of flotation device is gas, solid-liquid three-phase mixed flow body, and its internal flow is extremely complex, the difficulty of research work
It is very big.The research to flotation device interior flow field is mainly based upon water medium at present, using the method for measuring, this side
Although method is intuitively, conveniently, water medium can only be measured, the three-phase mixed flow body of gas, solid-liquid can not be carried out
Determine.In addition, flotation device is primarily present liquid level magic flower in actual motion, ore pulp short circuit, froth bed thickness is unstable,
The problems such as mineral recovery rate is relatively low.The presence of these problems illustrates that people do not grasp also to the flowing law inside flotation device,
Understanding especially to internal gas, solid-liquid three-phase flow field is insufficient, so being floated from flotation device stir system design, reduction is improved
Select machine operational management cost and save energy angle and say, it is ten to improve the stirring efficiency of flotation device, improve its reliability of operation
It is point necessary, further the interior flow field of research flotation device to this highly significant.
Flotation device is generally made up of transmission device, bearing body, foam pushing device, stirring system and cell body.Flotation device is mainly by stirring
The system of mixing realizes mineralising and the sorting of mineral, and stirring system mainly includes impeller, stator and spindle unit.Wherein, flotation device
The composite construction of impeller and stator is Uniting and the one group of component used cooperatively, is most important main body in each part of flotation device
Component.Ore pulp is through between the intake impeller lower blade of impeller lower blade inner edge, at the same time, the low-pressure air fed by outside passes through sky
The aperture on qi leel orchestration periphery enters between impeller lower blade.After ore pulp and air are sufficiently mixed between impeller lower blade, by leaf
Take turns the discharge of lower blade outer rim.And stator from tangential is changed into the direction of motion for being thrown away ore pulp by impeller axially, to make the ore deposit around impeller
Slurry Xu Su is spread apart, to ensure that the relative velocity of ore pulp and blade end at impeller outlet is maximum, so as to lift inflation and stirring effect
Really, more stable froth zone is formed., it is necessary to by the stronger pumping ability of the rotation generation of impeller and by force when flotation device is operated
Strong turbulent flow stirring, so as to form circulation, increases target minreal mineralising probability.With the increase of mine capacity, flotation device is
Develop to maximization direction, this necessarily causes the load and agitated flow of flotation device to increase therewith, therefore, improve flotation device stirring
The service life of system, to reduce its power consumption particularly important.Current both at home and abroad impeller and stator rim that mine floatation machine is used are
Linear, though this form impeller and stator processing are simple, are easier to abrasion, mixing effect and dispersion effect are undesirable, hold
Easily there is liquid level magic flower etc., and energy consumption is higher, directly affect floatation indicators, restriction production.
The content of the invention
Excessive for traditional flotation device stirring system power and load, service life is shorter, mineral syrup liquid is unstable, magic flower is serious
The problems such as, the present invention devises a kind of stir system design of air-inflated flotation device, and the structure can significantly improve flotation device
Stirring efficiency and turbulence intensity, increase the mineralising probability of mineral grain, improve air decentralization, beneficial to the lifting of flotation effect,
