Abstract

The utility model relates to a continuous centrifugal ore separator, which is suitable for separating various ores. The utility model main comprises a paraboloidal shaped form revolving drum, and the main central shaft of the drive center of the main movable wheel and the revolving drum do rotatory movement by the drive of electrical motor and speed reduction devise. The axial direction driving device of variable motion makes the main central shaft and the revolving drum do straight reciprocating motion, and the revolving drum rotates with specific speed and does axial movement, so as to achieve the separating ores.

Description

Continuous centrifugal ore separator

The utility model belongs to preparation equipment, particularly a kind of centrifugal ore separator of continuous operation.

Existing centrifugal ore separators is service intermittent mostly, puts into ore pulp, sorting, goes out process such as concentrate and is undertaken by a cover electrical equipment control, because electrical equipment is complicated, is out of order easily, and perhaps control is inaccurate slightly, does not just reach and gives the effect of thinking.And, under the bigger situation of centrifugal force, easily form the fine and close bed of material and influence separating effect.

The patent of invention of the patent No. 85102190 has proposed a kind of continuous centrifugal concentrating machine that adopts inside and outside barrel configuration, and structure is more complicated still.

The purpose of this utility model is to design a kind of energy and realizes continuous ore-dressing practice, and is simple in structure, is convenient to Operation and Maintenance, and can adapts to the continuous centrifugal concentrating machine of multi mineral sorting.

The utility model continuous centrifugal concentrating machine is realized with following technical scheme:

Continuous centrifugal concentrating machine has changed existing rotary drum (cone-element) structure, adopt a parabolic curve shape rotary drum (14), to drive the device that rotary drum rotates, this device has a motor (1), and decelerator (2), driving wheel (3), belt (4), driven pulley (5) rotate central shaft (16).Fixed seating with axial variable motion drive unit (5) on the bottom surface of central principal axis lower end and rotary drum (14) is fixedly connected is slidingly matched, and axially the variable motion drive unit can be the mechanical device that vibrator or other machine driving are done straight reciprocating motion.Central principal axis and central shaft holder cover (8) are connected with frame (12) with compression spring (9), and rotary drum is suitable for reading an annular concentrate hopper, and end opening has a tail-box (15), in addition ore pulp inlet tube (10), feed pipe (11).

The operation principle of this continuous centrifugal concentrating machine is such:

Know, a rotating speed is arranged by rational mechanics, can make particles all on this face all be in poised state: neither glide, also move on not for the paraboloid of revolution of a known parameters.If ore pulp flows into this parabola by mineral-feeding pipe (10), it just can not be by sorting.We make this specific rotation speeds of offspeed of this face now, and by formula as seen, this face just is equal to one and becomes gradient inclined-plane.The different particle of proportion just faces down or moves up along this with different speed in the ore pulp.Such as, can regulate rotating speed this moment, and ore pulp is flowed downward.Regulate the axially-movable drive unit again, material broke away from the drum face when rotary drum was moved downward, and make movement velocity greater than the gliding speed of heavy mineral the gliding speed less than light mineral.And when rotary drum returns upwards, owing to light, heavy mineral particulate all are close to rotary drum, so relatively move seldom.Like this, because the synthetic result of speed of related movement just can make the heavy mineral particulate move upward gradually and enter concentrate hopper light mineral particulate from following inflow tail-box.The effect of feed pipe is flushing concentrate and mine tailing.Like this, ore pulp constantly flows into, and separates, and loosening, flushing has realized the continuous sorting operation.

The utility model continuous centrifugal concentrating machine has the following advantages:

1. this centrifugal ore separator need not complicated electric control system, as long as give earlier machine adjustments is arrived proper state, and power turn-on just can continuous operation.

2. the gangue particulate that proportion is little is swept away by water, heavy mineral by stream on, constantly be washed, be thrown out of at last by loosening, has avoided forming the fine and close bed of material and be mingled with gangue, thereby mineral can be by fully sorting.

3. the rotating speed of this machine can be regulated for wheel within the specific limits continuously by the very simple bolt cam skin of structure.Realize infinitely variable speeds.Thereby might select reasonable parameter, thereby wide adaptability to different mineral.

4. this machine can be by regulating parameters such as rotating speed, axial force, washing water quantity adapting to the separation operation of different ore pulps, as all separating effectively or enrichment to multiple ore pulps such as lead, zinc, tin, tungsten, molybdenum, gold dusts, thereby applied widely;

5. this body is long-pending little, in light weight, simple in structure, conveniently moving.Both be fit to the open-air use of self-employed worker, be suitable for selecting factory's fixed installation again.

6. this acc power is little, economize on electricity.

Concrete structure below in conjunction with this continuous centrifugal concentrating machine of description of drawings.

Fig. 1 is the structural representation of continuous centrifugal concentrating machine.
