Description
Technical field
The present invention relates to technical field of mineral processing equipment, and particularly a kind of processing capacity is big, the efficiency of separation is high and makes pole
The fine inclined plate that fine obtains effectively sorting recycling floats sorting machine again.
Background technology
The mineral materials operation separated with density variation sorting, the operation sorted with particle size differences cry be classified,
In mineral manufacture field, fine mineral classification and sorting is always research hotspot.At present, setting for fine particle stage material classification and sorting
Have minor diameter hydraulic classification swirler group, spiral, flotation column and TBS equipment etc..
Traditional sorting mineral equipment, which to material can be classified, either to be sorted, however, due to mineral materials feature
With structural limitation of additional fractionation screening installation itself so that Mineral Classification separating effect is unsatisfactory, it is impossible to meet fine grained ore deposit
The requirement of object high-precision sorting, so as to waste vast resources.Existing spiral sharpness of separation is low and takes up a large area；It is floating
Column is selected to sort superfine particle material effective, since bubble load capacity is limited, the flotation column grain sorting effect slightly thick to granularity
It is bad；The fluidisation water speed of TBS sorting machines cannot exceed the termin al velocity of material, so its treating capacity is small.Thus, to mineral
Separation classification device, which is innovated and transformed, just seems extremely urgent.
It integrates, traditional separation classification device has the following disadvantages：1. it takes up a large area and treating capacity is low；2. sorting point
Grade effect is undesirable；3. equipment performance is single, superfine particle material can only be handled or handle the slightly thick particle of particle.
The content of the invention
Technical problem：The invention aims to provide the fine inclined plate that a kind for the treatment of capacity is big, efficient and float again to divide
Machine is selected, to solve the problems, such as traditional preparation equipment to mineral especially cannot effectively sort to fine mineral comprehensively.
Technical solution：The fine inclined plate of the present invention floats sorting machine again, including PID control instrument, overflow launder and sorting
Column,：The sorting column includes vertical groove body, thin vertically groove body and inclination groove body, and thin vertical groove body and inclination groove body are in not advise
Then alphabetical Y-shaped structure is connected on vertical groove body, several hang plates, the tipper are equipped in the tipper body
The top of body and thin vertical groove body is respectively equipped with overflow launder；The vertical groove body top is equipped with feeding mouth, valve；Vertical groove body
Lower part be equipped with back taper cloth flowing plate, the lower section of back taper cloth flowing plate be equipped with the water inlet pipe that is communicated with external water inlet pipe and with it is external
The air inlet pipe of air inlet pipe connection, the center of vertical groove body are equipped with underflow discharge gate.
The sorting column is square or circular.
Several described hang plates are parallel to be applied in the card slot for tilting groove body, and the spacing of hang plate is adjustable.
The flow control valve being connected with PID control instrument is equipped at the underflow discharge gate.

Advantageous effect：By adopting the above-described technical solution, the present invention fluidization using vertical channel and inclination simultaneously
The invigoration effect of slot so that relatively narrow parallel oblique plate spacing increase fluidizing velocity, so as to increase mineral treating capacity；It can cause
The fluidisation water speed rate fed exceeds the terminal velocity of material；The in vivo hang plate of tipper can generate shear action to material,
Improve stock grading effect, and then improve the processing capacity of device, improve sorting classifying effect, improve classification and sorting efficiency, carry
Format high throughput.By mineral materials fluidisation water with microvesicle respectively by vertical groove body bottom inlet channel and admission line through cloth stream
Plate moves upwards together into vertical groove body, mineral material is fed by the feeding mouth of vertical groove body middle and upper part, under the effect of gravity
It is moved downward along vertical groove body, meets with current and microvesicle and generate fluidization and suction-operated；Superfine mineral grain is in bubble
Suction-operated under into thin vertical channel body, forming froth bed on vertical groove body top, foam entrainment of superfine particle material into
Enter overflow launder, form superfine particle concentrate；Slightly thick mineral grain tilts groove body, density little particle under flow action into right side
It is moved upwards along ramp way into overflow, density bulky grain moves downwardly into vertical groove body along ramp way, in ascending water
It suspends again under the action of stream, understands some microvesicle and enter in tipper body, ascending current can be to particulate thing between hang plate
Material generates Strong shear effect, makes bubble quickly into overflow, the big particle of density, then under the castering action of microvesicle along inclining
Inclined plate upper surface is quickly slided, and so as to improve grading effect of the material in hang plate, and then improves the processing capacity of device
And the efficiency of separation；The big coarse grain mineral grain underflow of final density is controlled from underflow discharge mouth by flow control valve and discharged.It is led
Advantage is wanted to have：
1st, the present invention sets on vertical groove body and tilts groove body.Make the mineral materials that must be sorted from vertical groove body top into
Entering in tipper body, bigger fluidizing velocity can be obtained, fluidizing velocity is less than the limitation of material termin al velocity before breaking through,
Material under higher fluidisation water speed is sorted, improves the treating capacity of the device；
2nd, for mineral materials when being flowed in tilting groove body, density is big, and the big material of granularity quickly sinks on hang plate and sliding
Enter to hang plate bottom in vertical channel body, be subject to the fluidization of the external adding water of vertical groove body bottom, a portion is lighter
Small particle floats again, into tipper body in carry out classification and sorting so that it is further back to the in vivo material of vertical channel
It reduces, keeps the stabilization of bed density, obtain good separating effect；
3rd, the hang plate tilted in groove body is arranged on, shearing castering action can be generated to material, to realize to material
Classification.Hang plate is inserted in the card slot for tilting groove body, and the quantity of card slot is more and uniform, change hang plate easy to operation
Quantity and plate spacing, so as to obtain different grading effects；
4th, the thin vertical groove body on vertical groove body top is arranged on, mineralising microvesicle bears superfine particle mineral directly from vertical channel
Body forms froth bed, foam enters overflow launder entrainment of superfine particle material, is formed into thin vertical groove body on vertical groove body top
Superfine particle concentrate；
5th, PID automatic control systems can accurately control discharge gate aperture, further strengthen the stabilization of bed density, ensure
Higher sharpness of separation reduces the influence of human factor and pan feeding fluctuation to sorting mineral effect；
6th, the present invention tilts addition on groove body on right side and tilts groove body, and parallel oblique board is set in tipper body
Slot, pocket numbers are more, are conveniently adjusted the quantity and plate spacing of hang plate, can be directed to different minerals and be tilted into accommodating adjust
The spacing of plate improves the efficiency of separation.
