The large granular materials that the result of forward cloth has formed the agglomerate on the cooler all is arranged in above the bed of material, and small particles material all is arranged in below the bed of material.When the forward cloth, small particles material is pressed close to chute plate and is arranged into lower floor, and large granular materials takes the lead in being arranged in above the small-particle bed of material because rolling speed is fast.What adopt in the agglomerate process of cooling at present is the air blast type of cooling, cooling air is blown into the bed of material from bottom to top, the result is arranged in the cooling that following small-particle at first is subjected to freezing air, and what arrange that superincumbent large granular materials is subjected to is the cooling that sees through the air that comes from the small-particle bed of material, this part air has absorbed in a part of heat of the small-particle bed of material through heat exchange, the relative variation of cooling performance.Such result is opposite with hope, be difficult for the refrigerative large granular materials not only cool off after, and cooling performance is poor.Large granular materials is cooled off better, must increase the cooling power consumption, increased running cost thus.In addition, because the large granular materials postcooling, the oversize material in the agglomerate is not easy cooling fast and divides, thereby sinter quality will be affected.In factory construction,, therefore increased cost of investment because the influence of cooling performance needs configuration bigger cooler area and more powerful cooling blower.
The utility model content
Task of the present utility model provides a kind of improved reverse material distribution of agglomerate cooler structure, it is poor that it has solved in the agglomerate process of cooling large granular materials cooling performance, and need configuration bigger cooler area and more powerful cooling blower, increase the problem of cost of investment thus.
Technical solution of the present utility model is as follows:
A kind of reverse material distribution of agglomerate cooler structure, it comprises that sinter machine unloads ore deposit chute and cooler, cooler is circular cooler or straight-line cooler, unload at sinter machine and to be provided with the cloth funnel between ore deposit chute and the cooler, the bottom of described cloth funnel is flats, flat funnel bottom tilts to install to the cooler direction of retreat, forms the cloth funnel opposite with the cooler direction of travel; The flat bottom of described cloth funnel is equipped with segregation grid grating filtration unit.
By reverse material distribution structure of the present utility model, agglomerate is in operational process, large granular materials be arranged in cooler below, small particles material be arranged in cooler above, large granular materials is subjected to better cooling, improve the cooling performance of agglomerate, thereby improved the output and the quality of agglomerate.In factory construction, because the improvement of cooling performance can be disposed littler cooler area and more low power cooling blower, thereby reduced cost of investment.
Reverse material distribution structure of the present utility model is a cloth funnel that will be connected between sinter machine mineral blowtank and circular cooler or the straight-line cooler, tilted to change into to the inclination of cooler direction of retreat to the cooler working direction by original funnel bottom, its primary structure form is formation and circular cooler or the opposite funnel of straight-line cooler direction of travel.In order to strengthen this cloth effect, designed segregation grid grating filtration unit in funnel bottom, with further reinforcement segregation effect.
The utility model adopts the reverse material distribution structure, the large granular materials that agglomerate is formed on cooler is arranged in below the cooler bed of material, small particles material is arranged in above the cooler bed of material, thereby in the sintering process of cooling, cooling air is bottom-up to be blown into by air blast, makes to be difficult for the refrigerative large granular materials and to obtain cooling earlier, obtains easily cooling behind the refrigerative small particles material, thereby reduced the cooling power consumption, reduced running cost.Owing to large granular materials cooling earlier, the oversize material in the agglomerate cools off fast easily and divides, and has reduced bulk agglomerate ratio, thereby has improved sinter quality.

Embodiment
Referring to Fig. 1 and Fig. 2, a kind of reverse material distribution of agglomerate cooler structure of the present utility model comprises that sinter machine unloads ore deposit chute and cooler, and cooler is circular cooler 4 or straight-line cooler 5.
Between unloading ore deposit chute 2 and circular cooler 4 or straight-line cooler 5, sinter machine is connected a cloth funnel, the bottom 3 of this cloth funnel is flats, flat funnel bottom 3 tilts to install to the cooler direction of retreat, forms the cloth funnel opposite with the cooler direction of travel.Agglomerate 1 is through cloth funnel reverse material distribution on cooler, and promptly to unload the discharging materials flow direction of ore deposit chute 2 opposite with cooler progressive direction for sinter machine.The shape and size of cloth funnel can be according to the particular case of cooler, agglomerate, and different owners' different demands design.
Referring to Fig. 3, in flat bottom 3 designs of cloth funnel segregation grid grating filtration unit 6 is housed, strengthened the segregation effect like this.This segregation grid grating filtration unit 6 is equipped with grating framework 61 and grid grating 62, and grid grating 62 is laid in the grating framework 61, helps small-particle agglomerate under the filter sieve.Settle smooth slide carriage 63 in the bottom of grating framework 61.The gap of grid grating 62 is made up-small and down-big, smallest particles is arranged in topmost, slightly bigger particle is arranged in thereafter, the bulk particle then rolls on smooth slide carriage 63 and is arranged into the bottom, thereby reached cooler bed of material size distribution from bottom to top for arranging from big to small, under the air blast cooling, can obtain better cooling performance.For the grid grating, can be designed to the base plate of different slits, different material system, different style, different angles according to the particular case of sintering process, cooler and agglomerate, distribute in the hope of reaching from bottom to top for from coarse to fine material.
During work, agglomerate 1 on the sinter machine is discharged in the ore deposit chute 2, when agglomerate 1 passes through grid grating 62 downwards in chute 2, the small-particle agglomerate at first spills from grid grating 62 gaps, bigger particle continues to roll downwards, progressively sift out, bigger particle slips out from bottom light scooter 63 always.Because grid grating 62 is oppositely to install, the macrobead that slips out after therefore drops on the bottom of cooler, and along with advancing of cooler, above the material from coarse to fine that spills from grid grating 62 gaps was arranged in successively, fine particle was then topmost.
