Description
Technical field
This utility model relates to the pipe flow section flotation unit of a kind of Cyclonic-static fine-bubble flotation column, specifically one rotation
Stream-static microbubble floatation column step strengthening pipe flow section mineralization device, belongs to technical field of mineral processing.
Background technology
In prior art, Cyclonic-static fine-bubble flotation column, it is mainly used in the floating of coal, non-ferrous metal and non-non-ferrous metal
Choosing, mainly for particulate and the flotation of mineral particles.Its agent structure include flotation column section (or claim post segregation section dress
Put), eddy flow section (or claiming cyclonic separation section), bubble occur and pipe flow section (or general name flotation tube device) three parts.Described pipe flow
Section is the bubble generator downstream pipeline to eddy flow section entrance point of flotation column.Whole flotation column is a cylinder, its principle such as Fig. 1
Shown in.Post segregation section (post flotation) 11 is positioned at whole cylinder top；Cyclonic separation section 12 uses the aqueous medium eddy flow that post cone is connected
Device structure, and go to upper and lower the straight-through of structure with post segregation section and be connected.From rotational flow sorting angle, post segregation section is equivalent to be exaggerated
Cyclone overflow pipe.At the top of post segregation section, it is provided with spray header and froth concentrate storage tank；It is positioned at post minute to ore deposit point
From section middle and upper part, true tailings 13 is discharged by cyclonic separation section base opening.Bubble generator 14 is joined directly together into one with flotation pipeline section
Body, is individually arranged in flotation column cylinder external；It goes out to flow in tangential direction and is connected with cyclonic separation section cylinder, is equivalent to cyclone
Tangent line feed pipe.Airway is set on bubble generator.Flotation tube device 15 includes bubble generator and flotation tube section two parts.
Bubble generator is the critical component of flotation column, and it uses the internal structure being similar to jet pump, has dependence jet flow negative pressure certainly
Body introduces gas and gas is ground into the dual function (also known as self-suction microbubble generator) of bubble.Float at cyclone-static microbubble
In selecting post, the working media of bubble generator is the chats of circulation.Circulation ore pulp through pressurization enters bubble generator, introduces
Gas is also formed containing the gas of a large amount of micro air bubbles, solid, liquid three-phase system.Containing alveolate three-phase system height in flotation pipeline section
Degree turbulent flow mineralising, the most still keeps higher-energy state tangentially to enter at a high speed cyclonic separation section.So, flotation tube device is complete
While becoming flotation air inflation (self-suction microbubble generator) and highly turbulent mineralising (flotation pipeline section) function, again with tangential pan feeding
Mode defines the eddy flow field of force bottom flotation column.Flotation tube device is that all kinds of sortings of whole flotation column provide energy
Source, and substantially determine the energy state of flotation column.
This Cyclonic-static fine-bubble flotation column integrates adverse current, eddy flow and three kinds of mineralising modes of pipe flow, at fine-particle minerals
Sorting field is applied widely.Column-type floatation unit is for carrying out preliminary election to mineral, and the mineral that floatability is good can preferentially float
Choosing, obtains high-quality concentrate.Chats is sorted by eddy flow section separation unit further, obtains qualified tailings.In pipe flow section
Heterogeneous fluid tangentially enter at a high speed cyclonic separation section, separating further and edge for cyclonic separation with higher-energy state
Tangential and cyclonic separation is connected to form circulation.Pipe flow sorting environment is conducive to the recovery of strengthening fine fraction coal grain (-45 μm)；Countercurrently
Sorting environment is preferable for the recovering effect of coarse fraction coal grain (+250 μm).And rotational flow sorting advantage falls between, for
The recovering effect of middle sized coal grain (45-250 μm) is preferable.
Pipe flow section is the difficult fine mineral selected and bubble hit and adhesion during Mine By Cyclonic-static Micro-bubble Flotation Column
Main place, the turbulence intensity in this region decides the remineralization efficacy of fine-particle minerals, and is finally related to fine-particle minerals
The response rate.At present, the pipe flow segment structure employed in practice is light pipe, and turbulence intensity is less desirable, and whole pipe flow section
In turbulence intensity distribution more uniform, can only turbulence intensity required for adaption section grade mineral, thus can cause a large amount of
The Separate Fine-grained Minerals particle loss of monomer dissociation is in mine tailing.
Currently, improve pipe flow section turbulence intensity and currently mainly use two kinds of methods: one is, extend pipe flow segment length.Two are,
Use U-tube stream section.But both approaches is not notable for the increase of turbulence intensity, whole pipe flow section turbulence intensity is difficult to
Realize differentiation turbulent extent required for size fractionated scope mineral grain in adaptive mineral.In addition, U-tube stream section
Easily cause pipe flow section severely worn out, and extend pipe flow section and corresponding flotation column shell of column height can be made to increase, thus can increase
Equipment cost, reduces economic benefit.
