The present invention is characterized in that a high-frequency vibrating device is arranged at the upper part of a spiral body, and a vibrating spring device is arranged at the lower part of the spiral body. Under the action of high-frequency vibration in a vertical direction, the interlaminar repulsion force of ore flow is strengthened, the dispersing function and the layering function of the mineral particle groups are improved, and the separating effect is improved. The present invention has the advantages of simple structure, low cost, convenient operation, etc. The spiral chute ore dressing machine is a comparatively ideal gravity dressing device for recovering heavy metal minerals containing superfine particles at current.
Description
The present invention relates to a kind of screw chute ore dressing machine, particularly can be used for sorting the high-frequency vibrating spiral sluiceway ore drewwing machine of microfine heavy metallic mineral.
Screw chute ore dressing machine is a kind of gravity beneficiation equipment that sorts fine, usually its main element helicla flute and fixed mount constitute whole, it mainly utilizes mineral proportion, particle size differences produces solid phase dispersion, layering, according to the difference between the physical property valuable mineral is separated with gangue under the effect of mobilization dynamic promotion and gravity, inertia force, centrifugal force and frictional force.It does not need additionaling power, but this structure is just incompatible to sort valuable mineral from fine granule material, particularly reclaims quite difficulty of valuable mineral from-20 microns superfine material.People had once studied the vibrating screw chute ore separators of additionaling power for this reason, to improve sorting result, reported a kind of oscillatory spin chute ore separators " non-ferrous metal " fourth phase as the Soviet Union in 1969, its use has two eccentric steel central shafts and makes helical axis, make the helicla flute vibration, amplitude 3-4mm, helicla flute are suspended on the spring, because frequency is low, amplitude is big, and is still undesirable to the superfine material sorting result; " Xinjiang metallurgy " second phase nineteen eighty-three and " non-ferrous metal " second phase nineteen eighty-three have been reported a kind of rotary screw chute ore dressing machine of Xinjiang Institute of Metallurgical Technology development again, this equipment give ore deposit case, feed-tank, helicla flute all is fixed on the central shaft, drive conveyor screw by motor and gear and be low-speed rotation, and strengthen ore dressing process by the riffling or the cutting that on groove face, increase, it effectively sorts granularity is 0.6-0.05mm, but valuable mineral has 20-30% still to be lost in the micro-size fraction approximately, so the rate of recovery is not high; In " Chinese ore dressing scientific and technological information ", reported a kind of differential screw chute ore separators in December, 1986 again, its structure is that spiral chute produces differential motion under the drive of transmission mechanism, differential characteristics are high jig frequency, little stroke, but this device structure is complicated.
The objective of the invention is to improve on original screw chute ore dressing machine basis with not enough for the shortcoming that overcomes above-mentioned prior art, design a kind of screw chute ore dressing machine that high-frequency vibration device is arranged, it have simple in structure, sorting result good, the course of work is stable, easy to operate, characteristics such as can work continuously are a kind of novel and desirable gravity beneficiation equipments that reclaims heavy metallic mineral at present from superfine material.
High-frequency vibrating spiral sluiceway ore drewwing machine of the present invention, the groundwork principle still belongs to film concentration, but the conveyor screw of this equipment is done the time spent at the dither of the electromagnetic oscillation device that is subjected to being located at an end and the pressure stretch of other end vibrating spring device, make helicla flute produce high-frequency, the above-below direction vertical vibration of short arc, so that the mineral of desiring sorting in the helicla flute except that be subjected to general fixed helicla flute the intrinsic motive power, also be subjected to by the horizontal direction velocity gradient of this equipment generation and velocity gradient formed " solid " shear force of vertical direction, this power that makes progress is supported the effective gravity of ore particle and is suspended, it has strengthened the interlayer repulsion between the stream of ore deposit, help the loose of ore particle and dispersion, thin stream film can obtain big velocity gradient near the bottom, make between the ore particle of different densities bigger speed difference is arranged, the fine-grained heavy minerals settling height is short, helps reclaiming.If but vibrate excessively, and though loose ability is very big, then be unfavorable for the sedimentation of fine-grained heavy minerals, so that cause the heavy mineral chance of loss to increase, cause the rate of recovery to reduce.The present invention adopts the vertical vibration mode of high-frequency, short arc, runs off to reduce valuable mineral, improves the sorting result and the rate of recovery.
High-frequency vibrating spiral sluiceway ore drewwing machine of the present invention, comprise upper bracket, lower shoe, conveyor screw and central tube, it is characterized in that being provided with electromagnetic oscillation device at conveyor screw one end, the other end is provided with the vibrating spring device, the mobile that unifies of the flange by the central tube two ends.One end of the electromagnetic oscillation device in the mobile connects firmly on support with pull-rod spring; The vibrating spring device is fixed on the base plate with vibrating spring.Conveyor screw comprises the helicla flute that is fixed on the central tube, is positioned at the dispenser on helicla flute top and the feed pipe that cuts the material dispenser and be positioned at central tube top of bottom.Helicla flute of the present invention can be vertical, also can be tower dither helicla flute.So-called " vertical " be by equal diameter, etc. the spiral shell square, etc. the cubic parabola cross section spiral of groove width form; " tower " then is made up of the spiral of different-diameter, different spiral shell square, different groove widths, and its size increases progressively from top to bottom gradually, " tower " structure, use the effect of " tower " to be better than " vertical " generally speaking.
The upper and lower spring base of vibrating spring device involving vibrations spring and fixing spring, upper spring seat and vibrating chassis connect firmly, and lower spring cup and lower shoe connect firmly.
Electromagnetic oscillation device comprises electromagnetic vibrator and controller.Vibration frequency is 3000 times/minute.Adjust amplitude by controller in the process of sorting, generally being controlled at its preferable range of 0＜amplitude＜1mm is 0.1-0.2mm, the excessive or too small dispersion layering that all is unfavorable for ore particle.
Electromagnetic vibrator can adopt G series electromagnetic vibrator, available power 0.06-0.2kw, and vibration frequency 3000 times/minute, values for tuning is 0.9, supply frequency is 50 He Zhi.
