Abstract
The invention discloses a dry slag extractor with a slag separating device. The dry slag extractor comprises a slag conveyer belt, a magnetic roller, an iron grain conveying channel, a fine dust funnel, a coarse dust funnel and a slag crusher, wherein the magnetic roller is arranged at the tail end of the slag conveyer belt; the slag separating device is divided into the iron grain conveying channel, the fine dust funnel and the coarse dust funnel; in addition, a filtering grid is arranged above the fine dust funnel in an inclined manner; and a slag scrapper plate is arranged above the iron grain conveying channel. After being separated by the slag separating device, the fine slag is directly fed into the fine dust funnel after passing through the filtering grid, the coarse slag which cannot pass through the filtering grid is fed into the coarse dust funnel, is subsequently fed into the slag crusher, is crushed and is fed into a next procedure; iron grains or iron powder in the slag are/is adsorbed on the magnetic roller, and dropped into the iron grain conveying channel when the magnetic roller reaches a lowest point and has no magnetism. By adopting the dry slag extractor, the slag can be well separated, so that later procedures can be performed well, the slag entering the slag extractor is reduced under same conditions, the abrasion on the slag extractor is alleviated, the service life of the slag extractor is prolonged, and the slag extractor is worthy for popularization.
Description
Technical field
The present invention relates to the air-cooled dry slag discharging machine of field of metallurgy, relate in particular to a kind of dry residue extraction machine with slag separating device.
Background technology
In smelting iron and steel industry, can produce the surplus products such as slag, its composition comprises large block lime-ash, granular lime-ash, iron powder or abrasive grit.In these compositions, lime-ash can be used as material of construction and uses, and iron powder or abrasive grit can melt down utilization again.At present, the technology development of domestic and international ash and slag handling system and perfect, original water conservancy slagging-off technology environmental pollution is serious, and water loss is large, maintenance of the equipment amount is large, by the air-cooled dry dreg removing system of reliable, energy-conservation, water saving, environmental protection feature, is replaced gradually.The slag notch of air-cooled dry deslagging handling equipment is connected arrangement form with slag crusher at present two kinds: a kind of is that separate unit is direct-connected, another kind is direct-connected by two of electric three passes, adopt the form of the using and the reserved, no matter take which kind of arrangement form, today, the lime-ash of slag crusher was all that thickness is mixed slag, slag crusher can not grind the lime-ash that is less than particle size after cracking again, and such lime-ash still has wearing and tearing to slag crusher discaling roll during directly by slag crusher, slag crusher quick abrasion, work-ing life, short problem was at industry ubiquity.And iron powder or abrasive grit in slag charge are not separated, and have caused the waste of resource.
Summary of the invention
the technical problem solving
The object of the present invention is to provide a kind of air-cooled dry slag discharging machine with slag separating device, the iron powder in slag charge or abrasive grit, cinder slag, thin lime-ash can be separated.
technical scheme
Technical scheme of the present invention is as follows:
With a dry residue extraction machine for slag separating device, it comprises slag charge travelling belt, magnetic roller, and abrasive grit transfer passage, thin ash bucket, cinder bucket, slag crusher, magnetic roller is arranged on slag charge travelling belt afterbody; Slag separating device is divided into abrasive grit transfer passage, thin ash bucket, cinder bucket; In cinder bucket bottom, be provided with slag crusher.
In cinder bucket ingress, be provided with filtering grid.
Above abrasive grit transfer passage, be provided with dreg scraper.
The direction of filtering grid is tilted to down.
Distance between rasterization pipeline between filtering grid can be selected according to the size of slag particle.
beneficial effect
The invention has the beneficial effects as follows:
1. this equipment is can be well separated by the iron powder in slag charge or abrasive grit, cinder slag, thin lime-ash, reduces the wearing and tearing to slag crusher, reduces maintenance cost, has certain economic benefit.
2. in this equipment, the slag crusher that cinder bucket bottom arranges can be broken by large block lime-ash, is convenient to the carrying out of subsequent handling.
3. this equipment is separated the iron powder in slag charge or abrasive grit, can melt down recycling, has reached the object of resource rational utilization.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dry residue extraction machine with slag separating device provided by the present invention.
Fig. 2 is the structure iron of filtering grid.
In figure: thin ash bucket 9 cinder bucket 10 slag crushers of 1 frame 2 slag charge travelling belt 3 magnetic roller 4 roll shaft 5 dreg scraper 6 filtering grid 7 abrasive grit transfer passage 8
11 rasterization pipelines.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of this patent being done to one illustrates.
As depicted in figs. 1 and 2, a kind of dry residue extraction machine with slag separating device, it comprises slag charge travelling belt 2, magnetic roller 3, abrasive grit transfer passage 7, thin ash bucket 8, cinder bucket 9, slag crusher 10, magnetic roller 3 is arranged on slag charge travelling belt 2 afterbodys; Slag separating device is divided into abrasive grit transfer passage 7, thin ash bucket 8, cinder bucket 9; In cinder bucket 9 bottoms, be provided with slag crusher 10.
In cinder bucket 9 ingress, be provided with filtering grid 6.
Above abrasive grit transfer passage 7, be provided with dreg scraper 5.
The direction of filtering grid 6 is tilted to down.
Distance between rasterization pipeline 11 between filtering grid 6 can be selected according to the size of slag particle.
During this equipment work, slag charge is sent to end by slag charge travelling belt 2, then the cinder slag in slag charge falls together with thin lime-ash, thin lime-ash can directly enter in thin ash bucket 8 by filtering grid 6, thereby cinder slag cannot fall into cinder bucket 9 along filtering grid by filtering grid 6, then after slag crusher 10 fragmentations of cinder bucket 9 lower ends, enter subsequent handling; Iron powder in slag charge or abrasive grit are adsorbed on left magnetic roller 3, when arriving magnetic roller 3 lower-most point, just can fall under gravity in abrasive grit transfer passage 7; In abrasive grit transfer passage 7 upper ends, be provided with the dreg scraper 5 that leans forward, the upper limb of dreg scraper 5 touches the bottom surface of slag charge travelling belt 2, by dreg scraper 5, the remaining iron powder that is adsorbed on slag charge travelling belt 2 bottom surfaces is struck off, and falls into abrasive grit transfer passage 7.The present invention can be well separates the iron powder in slag charge or abrasive grit, thin lime-ash, cinder slag, thereby avoided the lime-ash that is less than slag crusher particle size after cracking to enter slag crusher, reduce the wearing and tearing of slag crusher, thereby extended the work-ing life of slag crusher, there is certain economic benefit; Iron powder or abrasive grit in slag charge are separated, and can melt down utilization again, are that the energy has obtained reasonable utilization; Iron powder in slag charge or abrasive grit, cinder slag, thin lime-ash be separated leaves the carrying out that is also conducive to subsequent handling.
