Abstract
The utility model relates to a device capable of controlling a bedding material distribution form, which is applied in the material distribution control field. The device comprises a bedding material funnel, the vertical wall surface of the funnel is provided with a through hole, a material blocking rod sleeve is arranged at the through hole, a material blocking rod is inserted in the material blocking rod sleeve and extends into the bedding material funnel to be directly contacted with the inclined surface of the bedding material funnel, the vertical wall surface of the funnel is also provided with an adjusting device, the adjusting device is connected with and controls an radial gate on the bottom of the vertical wall surface of the funnel, and the two sides of the bottom in the bedding material funnel are respectively provided with a blocking slab. Due to the inclined material blocking rod, the utility model increases the thickness of the bedding material in the horizontal middle part of a sintering pallet, the closer the bedding material is to the block plate of the pallet, the thinner the bedding material is, and even no bedding material is needed in a position closest to the block plate of the pallet, thereby changing the horizontal linear material distribution form into a material distribution form with the middle part higher than the two sides, improving the permeability of the horizontal middle part of the whole material layer, and reducing the edge effect of the pallet.
Description
Technical field
The utility model relates to material distribution control field, relates in particular to a kind of device that is applied to pallet grate-layer material in the iron and steel production, can control the cloth form of the grate-layer material in the pallet.
Background technology
Used a kind of pallet in each tame steel production enterprise at present, or title sintering machine, be used for the large-scale metallurgical sintering work, can be with different components, varigrained fine ore, rich ore powder sinters piece into, and part is eliminated sulphur contained in the ore, objectionable impurities such as phosphorus are its nuggets that can become blast furnace process.And in actual production process, pallet can inevitably produce edge effect, and the reason that produces edge effect will be better than gas permeability between the compound of chassis middle part far away mainly due to the breast board of chassis both sides and the gas permeability between compound, and the wet band of the mistake in the sintering process will further improve this edge effect, along with the superelevation bed of material, promptly expect popularizing of height＞600mm, the edge effect of pallet will be more obvious.The generation of edge effect can produce harmful effect to the yield and quality of sintering deposit and the reduction of energy consumption, and therefore suppressing and reducing edge effect is one of important work in the sintering process control.
Under the sintering edge effect, the burning velocity of band can reduce in the middle of the horizontal position of the bed of material, and the both sides burning velocity at the horizontal position of the bed of material further improves, and this just makes that the both sides air-flow velocity is too fast, causes solid fuel fully to burn.Air-flow velocity in the middle of the bed of material in the band upper strata is lower, make the more sufficient air supply of the solid fuel acquisition generation burning at this position cause bed of material superfusion, and its bottom can't completing combustion because of the air supply that can't obtain abundance.
Reduction edge effect at present mainly takes measures to be, by compacting is carried out on bed of material top, to reduce the porosity between compound, promptly gravitational compaction is carried out by heavier pressure roll in both sides, bed of material top, thereby reduce the resistance of the porosity of bed of material both sides with the raising air-flow velocity.This measure only is applicable to the low bed of material, promptly expect the sintering of height＜500mm, and when the thickness of the bed of material tends to superelevation bed of material sintering, it can't carry out compacting with the both sides bed of material fully by gravity, also just can't reach the porosity that reduces the both sides compound, and another way is to adopt grate-layer material, grate-layer material is supplies important in the sintering production process, it is positioned at the pallet bottom, and the upper strata of fire grate bar is the lowermost layer of mixing the bed of material behind the cloth.Grate-layer material produced the wet gas permeability of being with after can improving bed of material burning in the sintering process, avoided bed of material bottom to reduce because of crossing the wet gas permeability of shining into.Form behind the present grate-layer material cloth is the horizontal linear form, and this just makes the gas permeability of horizontal middle part of pallet bottom and both sides not have difference, also just can't reduce chassis both sides gas permeability.
Publication number CN101017056, open day on 08 15th, 2007 Chinese patent, disclose a kind of sectional adjust the sluice gate height, reduce edge effect adverse effect, improve sintering quality and sintering efficient, structure is simpler, the swinging funnel used for paving bottom flavoring of sintering machine littler, that manufacturing cost is lower takes up room.This swinging funnel used for paving bottom flavoring of sintering machine, comprise infundibular body, rotary gate and regulating gate device, rotary gate is installed in the middle part of infundibular body, and the regulating gate device is installed in the place ahead of infundibular body, and the height of the sluice gate of described regulating gate device successively decreases to both sides from the middle part.
This patent is that the grate-layer material gate is become split-type structural by integral body, the aperture of a middle gate is greater than the aperture of two side gates, make the grate-layer material behind the cloth become the low form of the high both sides of the middle bed of material bed of material, reach the gas permeability of improving the original horizontal middle part of the bed of material with this, reduce the gas permeability of bed of material both sides, and then the edge effect that slows down pallet.But grate-layer material is can be blocked by the grate-layer material particle between 10-20mm so the regulating gate, thereby cause the adjusting aperture of gatehouse can't reach perfect condition, should only be applicable to new sintering machine by middle grate-layer material gate structure simultaneously, and can't be suitable for in type sintering machine.
