Abstract
The invention provides a dry fluidized bed ore dressing apparatus, which comprises a magnetic separator housing, a magnetic drum and a fluidized bed. The magnetic drum is mounted in the upper part of the magnetic separator housing, the fluidized bed is mounted in the lower part of the magnetic separator housing, and comprises a constant-pressure chamber, an air distributor, small hoods and air chamber partitions. The constant-pressure chamber is under the air distributor, the air chamber partitions are mounted upon the air distributor to divide the space under the magnetic drum and over the air distributor into three areas which communicate with one another, and the small hoods are evenly distributed on the air distributor in the three areas. The dry fluidized bed ore dressing apparatus changes conventional top feeding into bottom feeding and converts solid material into fluid material, consequently, the contact area between the magnetic drum and the material is enlarged, the contact time is prolonged, and thereby sorting can be better carried out. When being discharged, the material has to pass through the range of the magnetic action of the magnetic drum, and thereby the phenomenon of tailing runaway can be effectively controlled. Moreover, the apparatus is convenient to maintain and easy to mount, and can stably and reliably operate.
Description
Technical field
The present invention relates to a kind of dry method fluid bed ore-dressing plant, belong to separation ore-sorting device field.
Background technology
In present dry magnetic separation process; Give the magnetic separator uniform distribution through distribution device (tradition is a dustpan), but require cloth continuously evenly and the bed of material thinner, this production method directly influences the production capacity of magnetic separator; And because a large amount of wrapped folder effects causes the ore dressing grade to be difficult to improve.And, then can cause a large amount of race tails because cloth is inhomogeneous, the rate of recovery can significantly reduce.
Summary of the invention
The technical problem that the present invention will solve is to overcome existing defective, and a kind of dry method fluid bed ore-dressing plant is provided, and prolongs the time of contact of mineral aggregate and magnetic separator magnetic devices, sorts better, improves the ore dressing quality, and effectively the generation of tail phenomenon is run in control.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Dry method fluid bed ore-dressing plant comprises magnetic separator housing, magnet drum, fluid bed.
Magnet drum is installed on magnetic separator housing top, and fluid bed is installed in the bottom, and fluid bed comprises isobaric storehouse, air distribution plate, little blast cap and air compartment baffle.
Air distribution plate is slit into two parts with magnetic separator lower housing portion spatial, and the air distribution plate below is isobaric storehouse, and isobaric storehouse one side is provided with the high-pressure blast import; Air distribution plate top is equipped with two air compartment baffles, and with the magnet drum below, the air distribution plate top is separated into three zones that are interconnected, and is respectively the cloth chamber, sorts the chamber, discharge chamber, on above-mentioned trizonal air distribution plate, is evenly distributed with little blast cap; Magnetic separator housing two ends are respectively arranged with charging aperture and discharging opening.
Top, cloth chamber is provided with charging aperture.Discharge chamber is provided with discharging opening.
Dry method fluid bed ore-dressing plant of the present invention changes down feed into by traditional last feed, by with the solid-state fluidised form that is converted into of material, thereby has strengthened the contact area of magnet drum and material, and has prolonged time of contact, sorts better.The magnetic action scope that material must pass through magnet drum when discharging, thus the generation of running the tail phenomenon can effectively be controlled.And this device is easy to maintenance, installs simply, and stable equipment operation is reliable.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Like Fig. 1, shown in 2, dry method fluid bed ore-dressing plant comprises magnetic separator housing, magnet drum, fluid bed.
Magnetic rolls choosing tube 2 and is installed on magnetic separator housing 1 top, and fluid bed is installed in the bottom, and fluid bed comprises isobaric storehouse 8, air distribution plate 9, little blast cap 10 and air compartment baffle 12.
Need the material of processing to get into cloth chamber 4 by charging aperture 3, high-pressure blast import 11 is sent into high pressure wind-force and is got into isobaric storehouse 8, through equally distributed little blast cap 10 outputs on the air distribution plate 9; Material is dispelled, reach fluidized state after, climb over air compartment baffle 12 by air compartment baffle 12 tops; Entering sorts chamber 5; Make material continue keep fluidized state by the little blast cap 10 that sorts 5 belows, chamber,, and sort between chamber 5 and the discharge chamber 6 and be provided with air compartment baffle because high-pressure blast dispels material; The magnetic action scope that this air compartment baffle must pass through magnet drum when making material discharge makes magnet drum 2 parts can immerse in the material after the fluidisation and carries out sorting of magnetisable material.Finally, magnetisable material is brought the finished product discharge zone into by magnet drum 2 and is discharged, and mine tailing continues to climb over air compartment baffle 12 and gets into discharge chamber 6 and by discharging opening 7 discharges, reach the ore dressing purpose.
Dry method fluid bed ore-dressing plant is provided with material level line 13.
Dry method fluid bed ore-dressing plant of the present invention changes down feed into by traditional last feed, by with the solid-state fluidised form that is converted into of material, thereby has strengthened the contact area of magnet drum and material, and has prolonged time of contact, sorts better.The magnetic action scope that material must pass through magnet drum when discharging, thus the generation of running the tail phenomenon can effectively be controlled.And this device is easy to maintenance, installs simply, and stable equipment operation is reliable.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
