Abstract
The present invention relates to vertical grinder iron remover for fine mineral slag powder production, and is especially continuous mineral slag iron remover. The mineral slag iron remover includes an iron powder lifting set comprising permanent magnetic drum, belt and cylinder installed below the mineral slag bin, a belt iron removing set installed behind the iron powder lifting set and a iron powder accepting trough. The present invention can separate most of the iron blocks and iron powder from mineral slag to protect apparatus, prolong the service life of grinding roller and grinding disc, raise yield and lower power consumption. The present invention is suitable for eliminating iron block and iron powder continuously during fine mineral slag powder production.
Description
Technical field
The present invention relates to the neutral worn iron device of slag micropowder production process, relate in particular to a kind of device of removing contained iron block and iron powder in the slag continuously.
Background technology
Slag is the byproduct in the steelmaking process, the ferrous powder granules that is difficult to eliminate is contained in the centre, because, slag is a kind of solid particle of on-fluent, therefore, the mechanism of the permanent tramp iron separator of existing belt has determined them can only remove the iron powder that passes through in the following 5 millimeters bed of materials of belt surface, and in the actual production on the feeding belt thickness of feed layer of slag at 150 millimeter (feeding is at 105 tons/hour), promptly the ferrous powder granules in the bed of material of 145 millimeters thick is inexpungible by the permanent tramp iron separator of original belt, these iron powders that are not removed have just together entered Vertical Mill, are disadvantageous to equipment.Existingly only can remove some ferrous powder granules and the metal bulk of exposing in the ribbon feeding process on the surface as belt self-unloading tramp iron separator and permanent tramp iron separator, about 80% ferrous powder granules can't be removed and directly enter Vertical Mill, will make Vertical Mill grinding roller, mill accelerated wear test like this, influence the service life of equipment, increase energy consumption, therefore, the deironing in the slag micropowder production process seems extremely important.And utilize equipment of the prior art to eliminate ferrous powder granules in the slag.
Summary of the invention
The technical problem to be solved in the present invention is in feeding ferrous powder granules free in the slag to be separated from slag in the slag micropowder production process, and has proposed a kind of device of removing contained iron block and iron powder in the slag continuously.
A kind of device of removing contained iron block and iron powder in the slag continuously of the present invention, this device comprises: the feeding belt of slag feed bin below between the front end below of feed direction feeding belt roller and Vertical Mill feeding belt, the iron powder lifting device is installed, the iron powder lifting device is made of permanent magnetic pulley, belt and cylinder, above Vertical Mill feeding belt, iron powder lifting device cylinder rear end is equipped with homemade belt tramp iron separator and the iron powder groove that connects material.
A kind of device of removing contained iron block and iron powder in the slag continuously of the present invention; compare with original belt, permanent tramp iron separator; metal derby and iron powder that original belt, permanent tramp iron separator can only be removed less than 1 ton in per 24 hours; and after the iron powder lifting device has been installed; metal derby that same feeding amount and same slag were removed in 24 hours and iron powder amount are more than 3 tons; and the iron powder overwhelming majority that in the past is embedded in the middle of the slag is separated; thereby reached protection equipment; prolong the service life of grinding roller, mill; improve output, cut down the consumption of energy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Accompanying drawing is a kind of apparatus structure schematic diagram of removing contained iron block and iron powder in the slag continuously of the present invention.
The specific embodiment
Shown in accompanying drawing, a kind of device of removing contained iron block and iron powder in the slag continuously, this device comprises: the feeding belt 9 of slag feed bin 10 belows is along feed direction, between the front end below of feeding belt 9 cylinders and the Vertical Mill feeding belt 3 iron powder lifting device 5 is installed, iron powder lifting device 5 is made of permanent magnetic pulley 11, belt 12 and cylinder 13, above Vertical Mill feeding belt 3, iron powder lifting device 5 cylinders 13 rear ends are equipped with self-control belt tramp iron separator 2 and the iron powder groove 1 that connects material.
Operation principle: the slag in the slag feed bin 10 is by claiming on the belt to feeding under the excellent lock, with 9 revolutions of feeding belt, the slag 8 that contains iron powder drops near the Disengagement zone 7 of permanent magnetic pulley 11 heads of iron powder lifting device 5, because when this zone slag falls, the slag that contains iron powder is in a kind of comparatively state of " fluffy ", therefore, ferrous powder granules in the whereabouts is under the effect of permanent magnetic pulley 11 magnetic force, acceleration is adsorbed onto on the permanent magnetic pulley 11, and the slag 6 that does not contain iron powder is just dropping under the gravity effect on the Vertical Mill feeding belt 3.Iron powder 4 on the permanent magnetic pulley 11 is with the revolution of iron powder lifting device 5, under the effect of belt 12, be forced to separate with permanent magnetic pulley 11, because, the position, setting point of iron powder 4 and pure slag 6 is different, and therefore, iron powder 4 always drops on the surface of pure slag 6, like this, as long as the slag 8 that contains iron powder is by behind the iron powder lifting device 5, and iron powder 4 just automatic " wafing " has arrived on the surface of pure slag, has reached the purpose of separating.Iron powder 4 after the separation and pure slag 6 travel forward with Vertical Mill feeding belt; when by self-control belt tramp iron separator 2; all iron powders 4 that are thus lifted to the surface are picked up by permanent magnetic pulley 14, and the iron powder of sending into belt tramp iron separator 2 connects material in the groove 1, so far; iron powder on the Vertical Mill feeding belt 3 in the slag is just separated; it is less to make that the slag enter Vertical Mill contains iron powder, thereby reaches protection equipment, prolongs grinding roller, mill service life; improve output, the purpose that cuts down the consumption of energy.
Claims (1)
1. device of removing contained iron block and iron powder in the slag continuously, it is characterized in that this device comprises: the feeding belt of slag feed bin below is equipped with the iron powder lifting device below the front end of feed direction feeding belt roller and between the Vertical Mill feeding belt, the iron powder lifting device is by permanent magnetic pulley, belt and cylinder constitute, above Vertical Mill feeding belt, iron powder lifting device cylinder rear end is equipped with belt tramp iron separator and the iron powder groove that connects material, its method of work is: the first step, under the slag in the slag feed bin to the feeding belt, turn round with the feeding belt, the slag that contains iron powder drops near the Disengagement zone of permanent magnetic pulley head of iron powder lifting device, ferrous powder granules in the whereabouts is under the effect of permanent magnetic pulley magnetic force, acceleration is adsorbed onto on the permanent magnetic pulley, and the slag that does not contain iron powder is just dropping under the gravity effect on the Vertical Mill feeding belt; In second step, the iron powder on the permanent magnetic pulley is forced to separate with permanent magnetic pulley under the effect of belt, always iron powder drops on the surface of pure slag with the revolution of iron powder lifting device; The 3rd step, iron powder after the separation and pure slag travel forward with Vertical Mill feeding belt, when by the belt tramp iron separator, all iron powders that are thus lifted to the surface are picked up by permanent magnetic pulley, the iron powder of sending into the belt tramp iron separator connects material in the groove, so far, the iron powder in the slag is just separated on the Vertical Mill feeding belt.
