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 current dry magnetic separation process, by distribution device (tradition is dustpan) give magnetic separator uniform distribution, but require cloth continuous uniform and the bed of material thinner, this production method directly affects the production capacity of magnetic separator, and due to a large amount of wrapped folder effects, cause ore dressing grade to be difficult to improve.And because cloth is inhomogeneous, can cause a large amount of race tails, the rate of recovery can significantly reduce.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of dry method fluid bed ore-dressing plant is provided, and extends the time of contact of mineral aggregate and magnetic separator magnetic device, sorts better, improves ore dressing quality, effectively controls the generation of running tail phenomenon.
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 bottom, and fluid bed comprises isobaric storehouse, air distribution plate, little blast cap and air compartment baffle.
Magnetic separator lower housing portion space is divided into two parts by air distribution plate, and air distribution plate below is isobaric storehouse, and isobaric storehouse one side is provided with high-pressure blast import; Air distribution plate top is provided with two air compartment baffles, and by magnet drum below, air distribution plate top is separated into three regions that are interconnected, and is respectively cloth chamber, sorts 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 lower feed into by traditional upper feed, by being converted into fluidised form by solid-state material, thereby has strengthened the contact area of magnet drum and material, and has extended time of contact, sorts better.When material is discharged, the magnetic action scope of magnet drum must be passed through, thereby the generation of running tail phenomenon can be effectively controlled.And this device is easy to maintenance, to install simply, stable equipment operation is reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, 2, dry method fluid bed ore-dressing plant, comprises magnetic separator housing, magnet drum, fluid bed.
Magnet drum 2 is installed on magnetic separator housing 1 top, and fluid bed is installed in bottom, and fluid bed comprises isobaric storehouse 8, air distribution plate 9, little blast cap 10 and air compartment baffle 12.
Magnetic separator lower housing portion space is divided into two parts by air distribution plate 9, and air distribution plate 9 belows are isobaric storehouse 8, and isobaric storehouse 8 one sides are provided with high-pressure blast import 11; Air distribution plate 9 tops are provided with two air compartment baffles 12, and by magnet drum 2 belows, air distribution plate 9 tops are separated into three regions that are interconnected, and are respectively cloth chamber 4, sort chamber 5, discharge chamber 6, on above-mentioned trizonal air distribution plate 9, are evenly distributed with little blast cap 10; 4 tops, cloth chamber are provided with charging aperture 3, and discharge chamber 6 is provided with discharging opening 7.
Need the material of processing to enter cloth chamber 4 by charging aperture 3, high-pressure blast import 11 is sent into high pressure wind-force and is entered isobaric storehouse 8, export by equally distributed little blast cap 10 on air distribution plate 9, material is dispelled, reach after fluidized state, climb over air compartment baffle 12 by air compartment baffle 12 tops, enter and sort chamber 5, make material continue to keep fluidized state by the little blast cap 10 that sorts 5 belows, chamber, because high-pressure blast dispels material, and sort between chamber 5 and discharge chamber 6 and be provided with air compartment baffle, must be through the magnetic action scope of magnet drum when this air compartment baffle is discharged material, magnet drum 2 parts can be immersed and in the material after fluidisation, carry out sorting of magnetisable material.Finally, magnetisable material is brought finished product discharge zone into by magnet drum 2 and is discharged, and mine tailing continues to climb over air compartment baffle 12 and enters discharge chamber 6 and discharged by discharging opening 7, reaches ore dressing object.
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 lower feed into by traditional upper feed, by being converted into fluidised form by solid-state material, thereby has strengthened the contact area of magnet drum and material, and has extended time of contact, sorts better.When material is discharged, the magnetic action scope of magnet drum must be passed through, thereby the generation of running tail phenomenon can be effectively controlled.And this device is easy to maintenance, to install simply, stable equipment operation is reliable.
