Description
Technical field
The utility model relates to a kind of concentrated magnetic plant, especially relates to the high concentration that adopts pressing plate and concentrates magnetic separator, can be used for two sections ball mills and gives sorting and the thickening operation of the concentrating of ore deposit, ferromagnetism iron mineral, also can be used for the recovery of coal preparation plant's dense media.
Background technology
Concentrated magnetic separator is a kind ofly to be used to improve pulp density and to have the magnetic plant that improves the concentrate grade effect concurrently along with what ore-dressing technique Progress in technique in recent years grew up.At present, the concentrated magnetic plant that uses mostly is traditional drum magnetic separator greatly both at home and abroad, and only a few is the drum magnetic separator that has pressure roller.The tradition magnetic separator is used to concentrate, weak effect not only, and technic index does not reach requirement, and because concentrate at cell body mine-discharging terminal and cylindrical shell extrusion friction, causes the premature wear of cell body and cylindrical shell, has influenced the service life of equipment.The not too big difference of technic index of the magnetic separator of band pressure roller and common magnetic separator do not reach the ore-dressing technique requirement, and manufacturing cost is higher.
Summary of the invention
The purpose of this utility model is exactly at the above-mentioned problems in the prior art, provides the high concentration of a kind of product design height, rate of recovery height, reliable in structure, long service life to concentrate magnetic separator.
For achieving the above object, the utility model is by the following technical solutions:
The utility model high concentration concentrates magnetic separator, comprise frame, bring cell body, cylindrical shell and drive unit thereof, magnetic system and adjusting device thereof, the drain separator of ore deposit case, the cylindrical shell bottom places cell body, magnetic system is built in the cylindrical shell, be provided with the mine tailing discharge gate in the bottom of cell body, be characterized in: it also contains pressing plate, and described pressing plate is positioned at cylindrical shell one side, and on the cylindrical shell horizontal center line; The big cornerite magnetic of described magnetic system's employing system, magnetic is that cornerite is 180～200 degree.
It is good that the magnetic field intensity that described magnetic is adopts segmentation to be distributed as, and the high field intensity that near the magnetic system the mine tailing discharge gate adopts high-performance rare-earth permanent magnet material to constitute is scanned the zone, and magnetic material drying zone and crush zone are the general magnetic field district.
Gap between described pressing plate and the cylindrical shell is adjustable continuously.Form the curve wedge-shaped crevice between pressing plate and the cylindrical shell and be advisable, finish the second dehydration of the bed of material by extruding.
Described cylindrical shell and pressing plate can install the wearing layer that high-abrasive material forms additional according to technological requirement on wear surface.
Described rotational speed of driving unit can on-line continuous be regulated.
Because to have adopted bigger magnetic is cornerite, pressing plate and adjustable drum speed to the utility model, make the magnetic material that enters cell body after by the magnetic force collecting, form the certain thickness bed of material at drum surface.After the bed of material broke away from liquid level with the cylindrical shell rotation, because the acting in conjunction of gravity, centrifugal force and magnetic force, the moisture in the bed of material began to separate.When the bed of material on the cylindrical shell runs to horizontal center line when above, bed of material dewatering speed is near stopping.Under magneticaction, the bed of material begins to enter the gap between pressing plate and the cylindrical shell, and is subjected to the pressure extruding of mechanical force, under the effect of extruding force, moisture spins off from the bed of material and discharges along stripper plate, and the bed of material after the extruding goes to the cylindrical shell opposite side by the drain separator removal with cylindrical shell.
Therefore, after the concentrated magnetic separator of the utility model high concentration adopts above technical scheme, have the following advantages:
(1) adopt big cornerite magnetic to be, magnetic is that cornerite is 180～200 degree, has finished collecting and two kinds of operations of dehydration in a circumference, has improved operating efficiency.
(2) increased the stripper plate forced dehydration, can guarantee that material concentration reaches the ore-dressing technique requirement.
(3) adopt online speed governing drive unit, can be supporting with most of technological processes, under different conditions, all can obtain satisfied technic index.
(4) in dewatering operation, only cylindrical shell and stripper plate are subjected to than galling, are convenient to carry out separately Wear-resistant Treatment, have improved the practicality of equipment.

The specific embodiment
In order to further describe the utility model, below in conjunction with accompanying drawing the utility model high concentration is concentrated magnetic separator and be described in more detail.
By Fig. 1, Fig. 2 and Fig. 4 as can be seen, to concentrate magnetic separator be to be that adjusting device 1, frame 2, cylindrical shell 3, magnetic are 4, drive unit 5, the cell body 6 that brings the ore deposit case, drain separator 7, pressing plate 8, to be adjusted bolt 11, wearing layer 13 etc. and constitute by magnetic to the utility model high concentration.
In the utility model magnetic architecture schematic diagram shown in Figure 3, magnetic field intensity adopts segmentation to distribute, use the high-performance rare-earth material in the bottom of magnetic system and constitute reinforcement district, magnetic field, common magnetic material is adopted at other position in magnetic system, thereby making the mine tailing discharge gate neighbouring is the high-intensity magnetic field district, and magnetic material drying zone and crush zone are the general magnetic field district.
Find out that in the pressure plate structure schematic diagram that the utility model shown in Figure 4 adopts and in conjunction with Fig. 2 movable pressing board 12 is fixed on the cell body 6 by link joint plate 10, bearing pin 9 and fixed connection plate 14, by regulating the distance between bolt 11 adjustment and the cylindrical shell 3.Wearing layer 13 on the pressing plate has guaranteed the service life of pressing plate.
The utility model in use, ore pulp is uniformly scattered onto cylindrical shell 3 surfaces from bottom to up through cell body 6, a large amount of magnetic materials at first is attracted to drum surface, rotates with cylindrical shell 3.The magnetic material that part is not held enters cell body 6 with ore pulp, is continuing by bottom high-intensity magnetic field collecting in last person's mouth process of flowing, thereby is finishing separation operation.
All are attracted to the magnetic material on the drum surface, rotate with the contrary flow of slurry direction of cylindrical shell to break away from liquid level.Under gravity and action of centrifugal force, the moisture in the bed of material begins to separate discharges, and after material turned over horizontal center line with cylindrical shell 3, the dehydration that is produced by gravity finished.Along with the rotation of cylindrical shell 3, the bed of material begins extrusion dehydration under the effect of pressing plate 8, and the moisture in the bed of material is extruded in a large number, reaches the concentration requirement of next step technology.After cylindrical shell 3 goes to no magnetic region, scrape the magnetic material layer by drain separator 7, finish All Jobs.
