Abstract

The utility model discloses an eccentric mineral separator with continuous discharge of fine mines, comprising a machine frame, a motor, a driving device, a rotary disc, a centrifugal disc and an outer cover. The utility model is characterized in that the centrifugal disc is round bench-shaped, a disc bottom is fixedly connected with the rotary disc, an inner surface of the centrifugal disc is provided with a spiral groove, and a disc wall in the groove is provided with a through hole of the fine mine. The center of the centrifugal disc is provided with a hanging ore pulp inlet pipe, an outer side of the centrifugal disc is sheathed with the sloping bottom cylindrical outer cover without contact, and the cover comprises an inner concentrate diversion groove and an outer tailings discharging groove. The utility model can be used for selecting heavy minerals and continuous discharging concentrate, so the utility model can reduce production cost and improve recovery efficiency.

Description

Concentrate continuous blow-down formula centrifugal ore separator

The utility model relates to a kind of preparation equipment, especially centrifugal ore separator.

At present, the centrifugal machine ubiquity that selects that uses in the mine the centrifugal pan unreasonable structure, makes the shortcoming that ore separators can not the continuous blow-down concentrate.And some centrifugal ore separator also need add the loosening heavy mineral of press water, causes beneficiation flowsheet water balance difficulty, needs to shut down the step concentrate that enters, and has influenced the continuity and the organic efficiency of ore-dressing practice.

The utility model provides a kind of concentrate continuous blow-down formula centrifugal ore separator, and it should be able to sort heavy mineral, and the continuous blow-down concentrate improves the concentrate organic efficiency.

The utility model comprises frame, motor and transmission device thereof, rotating disc, centrifugal pan, outer cover and the ore pulp input pipe to the centrifugal pan from top to down, it is characterized by:

(1) centrifugal pan of truncated cone-shaped, its heavy caliber be last, small-borely is fixedly connected for the rotating disc of trying to get to the heart of a matter, trying to get to the heart of a matter with described motor and transmission device driven rotary thereof; The dish inner surface is provided with fixedly helicla flute, and the Pan Bi in this groove is provided with the open-work of row's concentrate;

(2) by comprising that inboard concentrate guiding gutter and outside mine tailing dump the wedged bottom outer cover that groove constitutes, this outer cover is enclosed within described centrifugal pan outer periphery non-contiguously, and is fixedly connected with described frame.

The ore separators of said structure, motor and transmission device thereof drive centrifugal pan by rotating disc and rotate at a high speed, and at the bottom of ore pulp was given to centrifugal pan from the input pipe at top, ore pulp sorted along the helicla flute of centrifugal pan inner surface.Because action of centrifugal force, the mineral that proportion is bigger rise along helicla flute, and the open-work from centrifugal pan Pan Bi discharges, and collect at the concentrate guiding gutter of outer cover inboard, and come a place.Mineral that proportion is little or mine tailing drain into the groove that dumps in the outer cover outside, and come another place through the spiral fluted surface outside the upper edge hole of centrifugal pan.Thereby reach the purpose that sorts heavy mineral and continuous blow-down concentrate.Because continous way is discharged concentrate, do not need to shut down flushing discharging concentrate thing, do not need just can reach continuous ore dressing production operation with the loosening heavy mineral of press water yet, reduced production cost, improved organic efficiency.

Below, in conjunction with the accompanying drawings, the utility model is described in further detail.

Shown in Figure 1, be the utility model structure cutaway view.

In Fig. 1, each fulcrum of lower bearing bracket 6 is by the rubber shock absorber 13 supporting upper spiders 11 of truncated cone-shaped, vibration and minimizing noise during with buffering top machine works.In the centre of upper spider 11, be provided with rotating shaft 10 by upper bearing (metal) 8 and lower bearing 9 supportings, in the rotating shaft between two bearings 8 and 9 10, be provided with belt pulley.The rotating shaft 10 of this belt pulley constitutes the electric-motor drive device with the motor 4 and the belt pulley on the axle, driving-belt 5, upper bearing (metal) 8 and the lower bearing 9 that are fixed on upper spider 11 sides.Be fixed with circular rotating disc 7 in the upper end of rotating shaft 10, this rotating disc 7 is fixedly connected by the trying to get to the heart of a matter of centrifugal pan 1 of bolt and nut and truncated cone-shaped.The heavy caliber of this centrifugal pan 1 is last, and small-bore the dish inner surface is provided with fixing helicla flute 18 in order to try to get to the heart of a matter, and by the section of groove 18 as can be known, this groove is the rectangular coil groove, is provided with the open-work 16 of several row's concentrate in groove on the Pan Bi of differing heights.It in the centre of centrifugal pan 1 unsettled ore pulp input pipe 21 from top to down.In the outer periphery of centrifugal pan 1, be with outer cover 2 non-contiguously.Outer cover 2 is a wedged bottom multi-layer cylinder shape, dumps groove 17 by the mine tailing that comprises the inboard two-layer concentrate guiding gutter 15 and the outside and constitutes.Wherein, two-layer concentrate guiding gutter 15 is corresponding with the open-work 16 that centrifugal pan 1 Pan Bi goes up row's concentrate, receives the concentrate that this hole 16 is selected, and drains into a place by fairlead 12.Mine tailing dumps the mine tailing that groove 17 receptions are discharged from the mouth on the centrifugal pan 1, and by fairlead 14, drains into another place.Also introducing in concentrate guiding gutter 15 has wash tub pipe 3, so that cleaning robot.On outer cover 2, be provided with and the circular cover 20 of coincideing above the outer cover 2; The place, limit of this cover plate 20 is provided with the handle 19 of uncapping; Be provided with an open-work in the centre, ore pulp input pipe 21 passes from this open-work, and is suspended on the centre of centrifugal pan 1.
