Description
Technical field
The invention belongs to electrostatic separator and mineral electric separation field, especially for-1mm ~ 0.2mm grade, adopt electric separation method to carry out continuous print fluidization sorting, production, to obtain the dry separation equipment of more high-grade target minreal.
Background technology
Along with the mankind are to the increasing of mineral resources demand, the trend that the ore of new mining " was mixed " in " poor " " carefully ", and these features China show more obvious.The mineral resource development and utilization of China mainly concentrates on eastern region at present, and Conventional processing methods major part adopts the sorting process of wet type to carry out sorting.And west area drought and water shortage, develop efficient dry method preparation equipment and process matched therewith significant to the mineral resources utilizing west area abundant.
To material moisture, dry method ore dressing requires that height makes its principal element being subject to larger restriction in application, grinding process in current mineral dry production system can provide granularity, moisture satisfactory ore powder for follow-up sorting, current principal contradiction is to need effective dry separation equipment to carry out sorting to mineral.Gravity treatment, magnetic separation and electric separation are all possible dry separation methods.The mineral grain effect of gravity treatment to dry process fine fraction (-3mm) is poor, and magnetic separation can only sub-elect the mineral such as the magnetic magnetic iron ore of tool, to the magnetic mineral of tool are not helpless.Electric separation issues estranged from as theoretical foundation in External Electrical Field according to the material of the different electric charge of band, the difference of electrical property is all there is between any one mineral and another mineral, therefore in theory, electric separation method can carry out sorting to arbitrary mineral, is a kind of dry sorting method preferably.The invention provides a kind of electrostatic separator being sorting object with dry-type separation fine fraction mineral.
Summary of the invention
Object of the present invention is exactly the problem for above-mentioned prior art, provides a kind of vibrated fluidized bed electrostatic separator, solves prior art graded shot level mineral effect bad, the technical problem that the scope of application is wideless.
Object of the present invention is realized by following technical proposals:
A kind of vibrated fluidized bed electrostatic separator, comprise charging gear, pedestal, vibrated fluidized bed, electrode plate with high voltage, non-conductor belt and material collecting device, described vibrated fluidized bed by spring fitting on pedestal, the conduction working face of vibrated fluidized bed connects polarity high-voltage DC power supply, and the non-conductor belt be wrapped in outside electrode plate with high voltage is set above this working face, electrode plate with high voltage and this working face are arranged in parallel, and by wire connect with the conduction working face of vibrated fluidized bed connect the contrary high voltage source of electric power polarity, charging gear is arranged on one end of vibrated fluidized bed, the other end arranges material collecting device, described material collecting device comprises concentrate hopper and tail-box, tail-box is arranged near vibrated fluidized bed, the end of the corresponding non-conductor belt of concentrate hopper is arranged.
As preferably, material surge bunker is installed above charging gear.
As preferably, described vibrated fluidized bed comprises vibrator, air compartment and conductive fabric aerofoil, conductive fabric aerofoil forms the conduction working face of this vibrated fluidized bed, this conductive fabric aerofoil is fixed in above air compartment by insulating materials sealing, in air compartment, constant gas is provided by air inlet, and forming ascending air by conductive fabric aerofoil, vibrator is arranged on below air compartment.
As preferably, the corner of the corresponding material collecting device one end of described non-conductor belt is provided with hairbrush.
As preferably, the working face of described vibrated fluidized bed is to material collecting device one end inclination certain angle, and this adjustable angle.
Operation principle of the present invention is as follows:
Material enters in material buffer storehouse, is transported to conductive fabric aerofoil front end in the charging gear below falling under gravity.Vibrator produces vibration by driven by motor, thus drives vibratory liquefaction bed ensemble to produce vibration, and the adjustable vibration frequency of this vibrator is at below 60HZ.Described vibrated fluidized bed produces constant gas by air feed system and feeds in described air compartment, and air forms uniform air flow by described conductive fabric aerofoil; The material of vibrated fluidized bed front end is fed by described charging gear, fluidization under the acting in conjunction of gravity, vibration, air-flow, and point selections be moved into along conductive fabric aerofoil to vibrated fluidized bed afterbody below described electrode plate with high voltage, attracted in the electrostatic field that electrode plate with high voltage produces.
Described point of selections are entered along with the material in vibrated fluidized bed travels forward along conductive fabric aerofoil, conductor mineral grain charged rear spring under the contact action of conductive fabric aerofoil of the good conductivity in material, attracted by the described electrode plate with high voltage of top simultaneously, stick on the described non-conductor lightweight belt conveyor by driven by motor, fallen by described hairbrush brush to strap end with belt movement, fall in the concentrate hopper of described material collecting device and form concentrate.
The particle that in material, electric conductivity is poor, due to can not be charged, cannot be attracted by the electrode plate with high voltage of top, therefore drops in the tail-box of described material collecting device after the conductive fabric aerofoil of described vibrated fluidized bed moves to afterbody, collects and forms mine tailing.So far complete and once sort.
Compared with prior art, beneficial effect of the present invention is: reasonable in design, applied widely, can carry out sorting to arbitrary mineral; This electrostatic separator is specially adapted to-1mm ~ 0.2mm grade, carries out continuous print fluidization sorting, production, to obtain more high-grade target minreal.
