Abstract
The invention provides a purifying device of sponge iron dusting powder. The purifying device comprises an air blower (1), a feeder (4) and a wind cyclone (3), and further comprises a dust raising device (2), wherein an air outlet of the air blower (1) is connected with the bottom of the dust raising device (2) through a pipe; a waste pipe (14) is arranged on a pipe between the air blower (1) and the dust raising device (2); the top of the dust raising device (2) is connected with a feeding port of the wind cyclone (3) through a pipe; and an overflowing port of the wind cyclone is connected with an air inlet of the air blower (1) through an overflowing pipe (5). The purifying device can effectively perform the impurity removal and screening for the dusting powder, increases the percentage content of iron, prevents the resource waste due to the reason that traditional dusting powder only can be sold at a lower price as wastes, and contributes to improve the enterprise economic benefit and to realize the maximal utilization of national resources.
Description
Technical field
What the present invention relates to is the dust-removing powder producing in sponge iron shattering process, especially refers to a kind of sponge iron dust-removing powder purifying plant.
Background technology
Reduced iron powder is the important meals in metallurgy industry, to take sponge iron in raw material places it in tunnel furnace, to reduce processing, because sponge iron to be restored is block, therefore before reduction processing, need it to carry out break process, most domestic factory utilizes Raymond mill to carry out fragmentation to block sponge iron, in this broken process, can unavoidably produce a small amount of dust-removing powder, account for 10% of sponge iron total amount, because of the content of the iron in dust-removing powder lower, average is 92%-95%, lower than national standard, and at present in industry not to the purify effective ways of removal of impurities of dust-removing powder, therefore enterprise can only undersell dust-removing powder as waste material, and the price of this dust-removing powder is lower 2000 yuan/ton than the price of iron sponge powder, the performance of enterprises is exerted a certain influence, and be also a kind of waste to national resources.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sponge iron dust-removing powder purifying plant; this purifying plant can be purified to dust-removing powder; the impurity such as the charcoal in removal dust-removing powder, sulphur, acid; the degree that improves the iron in dust-removing powder is up to state standards it; turn waste into wealth; not only improve the economic benefit of enterprise, also protected national resources.
For solving the problems of the technologies described above, a kind of sponge iron dust-removing powder purifying plant provided by the invention, comprised gas blower, feeding machine, with wind-force swirler, described purifying plant has also comprised the wind-borne dust device, this the wind-borne dust device has comprised dirt hopper, dirt hopper is provided with feed chute, the inside of dirt hopper is provided with rotating spindle, rotating spindle is connected with the motor drive driving motion of dirt hopper bottom, the top of rotating spindle is provided with link span, the rotating spindle of take is evenly provided with several countershafts and is fixedly connected on link span as the center of circle, the bottom of dirt hopper is provided with several airborne dusts and shovels and be fixedly connected on corresponding countershaft, feeding machine is connected with the feed chute of the wind-borne dust device, the air outlet of gas blower is connected with the bottom of the wind-borne dust device by pipeline, on pipeline between gas blower and the wind-borne dust device, be also provided with waste pipe, the top of the wind-borne dust device is connected with the opening for feed of wind-force swirler by pipeline, the overflow port of wind-force swirler is connected with the blast inlet of gas blower by overflow spout.
For the convenient purification precision of controlling dust-removing powder, on described overflow spout and waste pipe, be all provided with by-pass valve control.
The invention has the advantages that: described sponge iron dust-removing powder purifying plant is simple in structure; with low cost; effectively dust-removing powder is carried out to removal of impurities screening; improve the degree of iron; having evaded traditional dust-removing powder can only undersell and the wasting of resources that causes as waste material, to improving economic benefit and the protection national resources of enterprise, all contributes.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described.
Fig. 1 is the structural representation of described sponge iron dust-removing powder purifying plant
In figure: 1 gas blower, 2 the wind-borne dust devices, 3 wind-force swirlers, 4 feeding machines, 5 overflow spouts, 6 by-pass valve controls, 7 dirt hoppers, 8 electric motor, 9 rotating spindles, 10 airborne dust shovels, 11 link spans, 12 countershafts, 13 feed chutes, 14 waste pipes, 15 collecting bins.
Embodiment
As shown in Figure 1: described sponge iron dust-removing powder purifying plant, feeding machine 4 is in-built dust-removing powder to be purified, feeding machine 4 is connected with feed chute 13, dust-removing powder enters in dirt hopper 7 by feed chute 13, dust-removing powder drops on the bottom of dirt hopper 7, electric motor 8 drives rotating spindle 9 rotations, the airborne dust shovel 10 that is positioned at dirt hopper 7 bottoms also starts rotation thereupon, during 10 rotation of airborne dust shovel, can sweep the dust-removing powder that drops on dirt hopper 7 bottoms, dust-removing powder is flown upward in dirt hopper 7, meanwhile, gas blower 1 is dried in the bottom of dirt hopper 7, distinguished and admirable at gas blower 1, between the wind-borne dust device 2 and wind-force swirler 3, form closed cycle, dust-removing powder is entered in wind-force swirler 3 by the pipeline at the top of the wind-borne dust device 2 under the effect of wind-force, the iron powder that in dust-removing powder, proportion is larger enters collecting bin 15 in the interior whereabouts of wind-force swirler 3, and the impurity that in dust-removing powder, proportion is less (charcoal, sulphur, acid etc.) be inhaled in overflow spout 5, and then enter in gas blower 1, impurity is arranged in the waste pipe 2 between gas blower 1 and the wind-borne dust device 2 and then is discharged from distinguished and admirable wafing, be arranged on the by-pass valve control 6 on overflow spout 5 and waste pipe 14, operator can be according to the needs of purification precision being regulated to the size of air quantity.Through experiment, technique scheme can improve the iron level 3% in dust-removing powder, indices all meets national standard, product on average can rise in value 1500 yuan/ton, and cost for purification is only 200 yuan/ton, greatly improve the economic benefit of enterprise, realized the maximum utilization of national resources, realized technical purpose of the present invention.
