Abstract
The utility model discloses a distributing sieve which comprises a left and a right edge frames (1) which have vertical edges and an upper and a lower support beams (2), wherein, the two ends of sieve strips are respectively embedded in the grooves of the upper and the lower support beams, and a sieve strip pressure plate (4) is fixed by bolts through the two ends of the upper and the lower support beams. The plane of the sieve strips is regulated to form an included angle with the horizontal surface, and the included angle is from 42 DEG to 55 DEG. The utility model has the advantages of simple structure, easy processing, easy installation and low manufacture cost. The utility model distributes sintering mixed material along the height direction of sintering trolleys in the way that the rough particle material is distributed under the fine particle material, so that the purpose that the air permeability of the sintering mixed material is obviously improved is achieved.
Description
The utility model is the equipment of solid being separated from solid about a kind of, a kind of roll-type sieve of more specifically saying so.
In ironmaking is produced, at first to carry out sintering to concentrate and fine ore, it is added in the blast furnace smelt again.Sinter mixture is not pressed coarse fraction following along the pallet short transverse with sinter mixture in the cloth process at present, and fine fraction is at last classification cloth, so sintered mixture ventilation can be poor, and sintering deposit yields poorly.
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of simple in structure, is easy to process and install, Cloth sieve that can the classification cloth.
For reaching above-mentioned purpose, the utility model provides a kind of Cloth sieve.It is by having the left and right frame that stands the edge, upper and lower backbar, grating and grating pressing plate composition.The two ends of grating are embedded in respectively in the groove of upper and lower supporting fine strain of millet, and the grating pressing plate is by the two ends bolting of upper and lower backbar.Sieved material and be not detained on compass screen surface by making, the reason angle is not excessive again has little time screening, and grating plane and horizontal plane angle are designed to 42 °～55 °.
By guaranteeing to be sieved material energy classification cloth non clogging screen seam again, be 25～35% with the compass screen surface designed porosity.
The utility model is simple in structure, is easy to processing and installation, and low cost of manufacture, and sinter mixture can be pressed coarse fraction descending fine fraction at last classification cloth along the pallet short transverse, and mixture ventilation can obviously be improved, and improves sintering deposit output.
Accompanying drawing 1 is the structural representation of this Cloth sieve.
1 expression has the left and right frame on upright edge in the accompanying drawing 1, the upper and lower backbar of 2 expressions, 3 expression gratings, 4 expression grating pressing plates.
With reference to the accompanying drawings 1, further specify the utility model by embodiment.
The utility model Cloth sieve has the upper and lower backbar 2 of groove by the left and right frame 1 that has upright edge, grating 3, and grating pressing plate 4 is formed.The two ends of grating 3 are embedded in respectively in the groove of upper and lower support beams 2, and grating pressing plate 4 is by the two ends bolting of upper and lower backbar 2, make grating pressing plate 4 be pressed on the groove surface of upper and lower backbar 2, with fixing grating 3.By make sieved material can classification cloth be 25～35% with the compass screen surface designed porosity.Cloth sieve is fixed by bolts on the former reflecting plate position, sintered compound feed bin exit.Adjust angle, making grating plane and horizontal plane is 42 °～55 °.Pallet travels forward along horizontal plane all the time in the sintering process, when sinter mixture falls through Cloth sieve from the sintered compound feed bin, because gravity effect, when pallet runs to Cloth sieve mouth place, at first cloth is to pallet for coarse fraction in the sinter mixture, and pallet runs under the Cloth sieve, fine fraction successively cloth on the coarse fraction sinter mixture, thereby the realization sinter mixture is pressed coarse fraction following along the pallet short transverse, and fine fraction is at last classification cloth.
