Abstract
The utility model discloses a device capable of removing iron from powdered coal dust and belongs to the technical field of magnetic separation equipment. The device comprises a rack, wherein a magnetic separation barrel is installed on the rack in a rotating manner; a magnetic system is arranged in the magnetic separation barrel; a sealing cover is installed at the periphery of the magnetic separation barrel in a sealed manner; the sealing cover which is provided with two ports corresponds to the position of the magnetic system; two pressing rollers respectively propping against the two ports are installed on the rack in a rotating manner; all the outer surfaces of the two pressing rollers prop against to the outer surface of the magnetic separation barrel; and a feed inlet and a dust outlet are arranged on the sealing cover. The device adopts simple and reasonable structure, magnetic mineral substances in the powdered coal dust can be effectively removed, and the environmental pollution caused by the powdered coal dust is reduced, therefore, the device can be widely applied to the magnetic separation industry.
Description
Technical field
The utility model relates to the magnetic plant technical field, relates in particular to a kind of deferrization of pulverized coal ash device.
Background technology
Flyash is to receive the thin ash of catching the flue gas behind coal combustion, and flyash is the main solid waste that the coal-burning power plant discharges.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; If entering water system can cause the river to silt up, and toxic chemical substance wherein also can work the mischief to human body and biology.Often all contain FeO, Fe in the industrial flyash
2O
3Etc. the magnetic mineral matter, because particle is thin, the moisture-sensitive bonding causes the conventional type magnetic separator to expect that the iron separating effect is not good.
At present, the dedicated magnetic optional equipment that does not also not carry out magnetic separation on the market at flyash, this is with fly ash grain is tiny, the characteristic close association of easy bonding, and the magnetic separation difficulty is big, and the magnetic separation effect is bad, and therefore, deferrization of pulverized coal ash is a difficult problem that perplexs numerous power plant always.
The utility model content
Technical problem to be solved in the utility model is: a kind of deferrization of pulverized coal ash device is provided, can removes the magnetic mineral matter in the flyash effectively, reduced the pollution of flyash to environment.
For solving the problems of the technologies described above, the technical solution of the utility model is: the deferrization of pulverized coal ash device, comprise frame, and be rotatablely equipped with the magnetic separation cylindrical shell on the described frame, be provided with magnetic system in the described magnetic separation cylindrical shell; Described magnetic separation cylindrical shell periphery is sealed and installed with seal closure, described seal closure is that the position is corresponding with magnetic, described seal closure has two ports, be rotatablely equipped with two pressure rollers on the described frame, described two pressure rollers lean with two ports respectively, and the outer surface of the outer surface of described two pressure rollers and described magnetic separation cylindrical shell all offsets, and described seal closure is provided with charging aperture and dust discharging opening.
As a kind of improvement, the pressure roller of described dust discharging opening position is connected with the mineral collection box, and described mineral collection box is fixedly installed on the described frame.
As a kind of improvement, described dust discharging opening is connected with air-introduced machine.
After having adopted technique scheme, the beneficial effects of the utility model are: because magnetic separation cylindrical shell periphery is sealed and installed with seal closure, two ports of seal closure all are equipped with the pressure roller that offsets and rotate with the magnetic separation cylindrical shell, seal closure is provided with charging aperture and dust discharging opening, flyash enters seal closure by charging aperture under the effect of air blast wind-force, in seal closure, be dispersed as iron dust containing, magnetic mineral matter in the dust just is adsorbed on the surface of magnetic separation cylindrical shell, rotation along with the magnetic separation cylindrical shell, magnetic mineral matter is with from magnetic, by magnetic is the pressure roller in downstream and the gap between the magnetic separation cylindrical shell, discharge seal closure, the dust after the deironing is just discharged from the dust discharging opening under the effect of air-introduced machine.Adopt this deironing mode, the agglomerate of bonding can be broken up de-ironing efficiency height, good iron removal effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1, magnetic separation cylindrical shell, 2, magnetic system, 3, seal closure, 31, charging aperture, 32, the dust discharging opening, 4, pressure roller, 5, the mineral collection box, 6, air-introduced machine, 7, frame.
The specific embodiment
As shown in drawings, a kind of deferrization of pulverized coal ash device comprises frame 7, is rotatablely equipped with magnetic separation cylindrical shell 1 on the described frame 7, and being provided with magnetic in the described magnetic separation cylindrical shell 1 is 2, and described magnetic is 2 to be fixedly installed on the described frame 7; Described magnetic separation cylindrical shell 1 periphery is sealed and installed with seal closure 3, described seal closure 3 is that 2 positions are corresponding with magnetic, described seal closure 3 has two ports, be rotatablely equipped with two pressure rollers 4 on the described frame 7, described two pressure rollers 4 lean with two ports respectively, and the outer surface of the outer surface of described two pressure rollers 4 and described magnetic separation cylindrical shell 1 all offsets, and described seal closure 3 is provided with charging aperture 31 and dust discharging opening 32, and described dust discharging opening 32 is connected with air-introduced machine 6.The pressure roller 4 of described dust discharging opening 32 positions is connected with mineral collection box 5, and described mineral collection box 5 is fixedly installed on the described frame 7.
Its operation principle is as follows:
Flyash enters seal closure 3 by charging aperture 31 under the effect of air blast wind-force, in seal closure 3, be dispersed as the iron content micronic dust, magnetic mineral matter in the micronic dust just is adsorbed on the surface of magnetic separation cylindrical shell 1, rotation along with magnetic separation cylindrical shell 1, it is 2 that magnetic mineral matter is with from magnetic, the gap that pressure roller 4 by dust discharging opening 32 positions and magnetic separation cylindrical shell are 1, discharge seal closure 3, fall into mineral collection box 5, dust after the deironing is just discharged from dust discharging opening 32 under the effect of air-introduced machine 6, collect through cyclone collector and sack cleaner then, be used for commercial Application.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
