Abstract
The invention discloses a kind of classifying segregation distributing and material supply chute, comprise the last chute of connection and following chute, be located at the interior windrow plate of chute, be total to material inlet with last chute and be provided with other chute in addition, and chute top is provided with tilting grating to other chute on being positioned in material inlet.Compared with prior art, advantage of the present invention just is: owing to big or small material layering can be distributed on the grate plate of revolution chassis, and material is following greatly, and less material is last, so just can effectively improve the gas permeability of the sintering deposit bed of material, reach the design cooling effect; Reduced the resistance of the sintering deposit bed of material simultaneously, air blast has reasonably been worked under the operating mode, thereby cut down the consumption of energy.
Description
Technical field
The invention belongs to sintering engineering central cooler apparatus field, relate in particular to a kind of feed chute.
Background technology
In the sintering work, the heat sinter after the fragmentation is evenly distributed in continuously by the feed chute on the grate plate of circular cooler trolley, and air blast blasts cold air gap under the grate plate, through the bed of material and carry out heat exchange with it, reaches the purpose of cooling sintering deposit.Existing feed chute is installed in central cooler annular chassis top, is box structure, and its structure is seen shown in Figure 1, by last chute 1, down chute 4, be located at chute 1 interior several parts such as windrow plate 2,3 and form.When heat sinter material during through last chute 1, because the effect of windrow plate 2,3 can be played the segregation distribution effect, but limited to the classification of large and small material.There is the bad problem of material gas permeability in the heat sinter bed of material that distributes through existing feed chute, thereby the heat exchange effect when influence cold air and passing through the bed of material, causes energy consumption bigger.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide a kind of on existing feed chute basis improved classifying segregation distributing and material supply chute.Can effectively improve the material gas permeability with heat sinter by large and small grain-size classification feed by this classifying segregation distributing and material supply chute, cut down the consumption of energy.
Realize that the technical scheme that the object of the invention adopts is: classifying segregation distributing and material supply chute comprises the last chute and the following chute of connection, be total to material inlet with last chute and be provided with other chute in addition, and chute top is provided with tilting grating to other chute on being positioned in material inlet, be provided with in the last chute can make through grating sieve less granularity material down be evenly distributed on the circular cooler trolley, be unlikely because of central cooler in out conductor speed differ and produce the different windrow plates of expecting partially of cloth thickness.
In the use, heat sinter material after the fragmentation is evenly distributed on the grate plate of revolution chassis continuously by feed chute of the present invention, owing to be provided with grating, during material process grating, the bulk material is blocked by grating and is distributed on the trolley grating plate earlier through other chute, less material under the sieve is distributed on the big material via upper and lower chute.
Compared with prior art, advantage of the present invention just is: owing to big or small material layering can be distributed on the grate plate of revolution chassis, and material is following greatly, and less material is last, so just can effectively improve the gas permeability of the sintering deposit bed of material, reach the design cooling effect; Reduced the resistance of the sintering deposit bed of material simultaneously, air blast has reasonably been worked under the operating mode, thereby cut down the consumption of energy.
Description of drawings
Fig. 1 is the structural representation of existing feed chute.
Fig. 2 is the structural representation of classifying segregation distributing and material supply chute of the present invention.
Fig. 3 is the operation principle schematic diagram of classifying segregation distributing and material supply chute of the present invention.
Among the figure, 1-upward chute, 4-following chute, 6-other chute, 5-grating, 2,3-windrow plate.
The specific embodiment
As shown in Figure 2, classifying segregation distributing and material supply chute comprise connection last chute 1 and following chute 4, be located at the interior windrow plate 2,3 of chute 1, be total to material inlet with last chute 1 and be provided with other chute 6 in addition, in material inlet, be positioned at chute 1 top and be provided with tilting grating 5 to other chute 6.During on-the-spot the installation, can on feed chute body, weld 6 to 8 bearings, be installed on the sintering machine main building afterbody platform by bolt.The direction of arrow is the motion path of material in the feed chute among the figure.
Operation principle of the present invention is seen Fig. 3, circular cooler trolley is in the direction of arrows along circumference operation, and the heat sinter of mean temperature about up to 800 ℃ feeds in this feed chute via unloading ore bucket 7, earlier through grating 5, bulk materials enters other chute 6 on the sieve, unloads earlier to circular cooler trolley; Sieve down less material enters in the chute 1, by 2,3 segregations of windrow plate after time chute 4 be distributed on the chassis; So just form the bulk material following, cobbing has substantially improved the gas permeability of the sintering deposit bed of material at the last bed of material, thereby has improved the not good phenomenon of sintering deposit cooling effect.
Material can make less granularity material be evenly distributed on the circular cooler trolley by windrow plate 2,3, is unlikely because of central cooler medial and lateral linear velocity differs and produces the different inclined to one side material of cloth thickness.
Owing to improved the gas permeability of the sintering deposit bed of material, thereby reduced the resistance of central cooler fan operation, so just reduced energy consumption effectively.When having realized sintering deposit classification, segregation distribution problem, estimate capable of reducing energy consumption about 10%.
Claims (1)
1, a kind of classifying segregation distributing and material supply chute, the last chute and the following chute that comprise connection, it is characterized in that being total to material inlet with last chute is provided with other chute in addition, and chute top is provided with tilting grating to other chute on being positioned in material inlet, be provided with in the last chute can make through grating sieve less granularity material down be evenly distributed on the circular cooler trolley, be unlikely because of central cooler in out conductor speed differ and produce the different windrow plates of expecting partially of cloth thickness.
