The sorter is the efficient and economical sorting equipment.
Description
The suspension electrostatic separator, a kind of benficiation machinery equipment.
In ore dressing field, the processing of fine granule material, mostly adopt the way of flotation and chemical mineral processing, its technological process complexity needs to add medicament, cost height, also has the pollution problem of waste water, known drum electrostatic separator is when handling less than the particulate below 200 orders, particulate material, disorderly disperse of fine fraction and fine fraction can occur to the adhering to of electrode, fine fraction adheres to and is difficult to realize thin layer evenly to phenomenons such as ore deposits to coarsely graded, makes assorting room to carry out.
The utility model provides a kind of suspension electrostatic separator, and this machine is electrically different according to mineral, and the structure that adopts high voltage and adapt with microfine is in order to reach the purpose of sorting fine granule material.
The utility model is to realize by following technical scheme.
One, forms structure
Mainly form by sorting unit I, gathering-device II, high voltage source III three parts.Sorting unit comprises: adjustable speed is given ore deposit pressure fan 1, flexibly connects flexible pipe 2, is regulated air-door actuator 3, feed port 4, comprise that every sieve 5, mine feeding bucket 6, electromagnetic oscillation device 7, blade corona electrode 8, plate-type grounding electrode 9, high-pressure electrostatic electrode 10, earth electrode 11, electric separatory vessel control valve 12, electric separatory vessel 13,14, gathering-device product collecting box 15, product collect blower fan 16, cloth bag 17, exhaust outlet 18, support 19 for the ore deposit, and high voltage source 20, high-voltage output end 21.Flexibly connecting flexible pipe for the ore deposit blower-use is connected with sorting unit, sorting unit does not have the joint adjustable high voltage power supply by ten thousand volts of 3-12 provides high voltage electric field, feed port is arranged on air inlet pipe and sorting unit junction, the sorting electric field is designed to a semicircular looped pipeline, the blade type corona electrode is located at the inwall lower end of semicircle pipeline, earth electrode is located on the inwall, the electrode cornerite can be the 50-120 degree, earth electrode is located on the inwall, the electrode cornerite can be large space and long high-tension electrostatic attraction electrode of distance and the earth electrode that 180 degree flow tanks adopt sudden enlargement, and product is collected 19 supportings of blower fan 16 usefulness supports.
The blade type corona electrode can be the 5-12 root, and the corona electrode cornerite can be the 50-120 degree, and semicircle ring-type conduit section is 20 * 40cm, number of corona can be 6,8.7 ten thousand volts of voltages can be 1350 rev/mins for the ore deposit rotation speed of fan, and gathering-device air exhauster rotating speed can be 1600 rev/mins.
Two, sorting flow process
Blast continuous flow by air blast 1, the rotating speed of regulating volume damper and air blast makes material inlet be in negative pressure state, start the electromagnetic vibrator in the charging gear, material is fed feed hopper, through giving the ore deposit every sieve, evenly fed in the half round ring shape pipeline electric field by feed port, voltage of electric field is preferably ten thousand volts of 3-12.Ore particle is under the effect of air-flow, and evenly dispersion suspension is in air, and ore particle obtains electric charge under the corona field effect, and along with the motion of air-flow, ore particle promptly contacts with earth electrode, electric charge takes place shift.The electric charge that the conductor ore particle obtains is grounded electrode and passes away, the non-conductor ore particle then can not pass away electric charge immediately, thereby this just makes ore particle have the different different movement locus that electrically produce, under the electric power effect, enter different electrical collecting boxs, under the effect of ore discharge system air exhauster, enter the ore discharge device and become the purpose that different electrical products reach the material sorting.
Advantage 1 that compared with prior art the utility model had, designed a semicircular looped pipeline as high voltage electric field and the structure that adapts with microfine, make the little mineral of electrical difference, in high voltage electric field, also can show evident difference, ore particle is suspended in the air, make air-flow by certain motion of making a detour, each ore particle all has abundant chance to obtain electricity, under the effect of the high-pressure electrostatic utmost point, enter different electrical gathering-devices, reach purpose the microfine sorting.
2, the gathering-device of ore particle adopts large space and the long high-tension electrostatic attraction electrode of distance and the earth electrode of sudden enlargement, helps reducing the influence of air-flow to charged back ore grain movement, and ore particle is separated according to electrical property difference under the effect of electric power.
3, hermetic product gathering-device, overcome fine granule material fly upward, leak, both improved the rate of recovery, reduced air pollution again.
