Technical field
The utility model relates to feeder system under a kind of blast furnace, is specifically related to a kind of two feeder systems under the blast furnace that struggles against of concentrating that adopt.
Background technology
In the larger blast furnace of volume, being everlasting to arrange under the groove concentrates bucket to improve feed capacity, its typical process configuration is: respectively by supplying burnt belt and supplying the barrow band, coke and ore are sent to respectively in the concentrated bucket of ore and the concentrated bucket of coke, concentrate bucket and coke to concentrate material transportation in struggling against to blast furnace in ore by main belt again, transport material in the blast furnace by blast furnace roof.
This mode can improve feed capacity to a certain extent.But owing to only having coke and ore all to only have one to concentrate bucket, when this concentrates bucket to break down, might cause the short-term of blast furnace to stop production.
The utility model content
The purpose of this utility model is to provide a kind of can further improve feed capacity, and the blast furnace short-term is stopped production can avoid some concentrated buckets to break down the time and the disadvantageous effect that causes, and the utility model provides following technical scheme.
Lower pair of feeder system of concentrating bucket of a kind of blast furnace comprises coke feeder system, ore feeder system:
Described coke feeder system comprises for burnt belt, a plurality of coke bins and feeding machine and the vibratory screening apparatus identical with the quantity of coke bin, coke bin is given by feeding machine and vibratory screening apparatus and is expected for burnt belt, and by for burnt belt coke being sent to the coke turnover panel, the coke turnover panel concentrates bucket to be connected with two coke;
Described ore feeder system comprises for the barrow band, many to storage ore deposit groove, each storage ore deposit groove is given by feeding machine or by feeding machine and vibratory screening apparatus and is expected the ore scale hooper, afterwards by for the barrow band ore being sent to the ore turnover panel, the ore turnover panel concentrates bucket to be connected with two ores through the ore scale hooper;
Coke concentrates bucket and ore to concentrate bucket that material is sent on the main belt, and by main belt material is sent to blast furnace roof.
Further scheme is: below the coke feeder system, there is one to return burnt belt, returning burnt belt is connected with the nut coke turnover panel, the nut coke turnover panel is connected with broken burnt sieve, and by broken burnt sieve with nut coke by the nut coke Belt Conveying to the nut coke storehouse, and by the nut coke bucket that is connected with the nut coke storehouse with nut coke as the part of ore by supplying the barrow band to carry.
Idiographic flow is as follows:
Particular case is concentrated bucket and ore to concentrate bucket to be arranged to respectively coke in coke and is concentrated bucket A, coke to concentrate bucket B and ore to concentrate bucket A, ore to concentrate bucket B for convenience of explanation.
The coke material is pressed following process flow operation:
Coke bin
Feeding device (Zhen Dongshai ﹠amp; Feeding machine)
For burnt belt
Turnover panel
Coke concentrates bucket A or coke to concentrate bucket B
Main belt
Blast furnace roof;
Ore materials is pressed following process flow operation:
Storage ore deposit groove
Feeding device (Zhen Dongshai ﹠amp; Feeding machine)
Disperse scale hooper
For the barrow band
Turnover panel
Ore concentrates bucket A or ore to concentrate bucket B
Main belt
Blast furnace roof;
In production practice, find, when concentrating bucket or turnover panel to break down, if thereby deal with improperly and may cause the confusion of feed order to affect the working of a furnace.
During normal production, the coke system is feed in the following order generally:
Coke is concentrated the bucket turnover panel to turn over to coke and is concentrated bucket A
For burnt belt and feeding device (Zhen Dongshai ﹠amp; Feeding machine) operation
The 1st coke charge charcoal enters coke and concentrates bucket A
Coke is concentrated the bucket turnover panel to turn over to coke and is concentrated bucket B
For burnt belt and feeding device (Zhen Dongshai ﹠amp; Feeding machine) operation
The 2nd coke charge charcoal enters coke and concentrates bucket B
Coke is concentrated the bucket turnover panel to turn over to coke and is concentrated bucket A
Coke concentrates bucket A to supply the 1st coke charge charcoal to blast furnace
For burnt belt and feeding device (Zhen Dongshai ﹠amp; Feeding machine) operation
The 3rd coke charge charcoal enters coke and concentrates bucket A
Coke is concentrated the bucket turnover panel to turn over to coke and is concentrated bucket B
Coke concentrates bucket B to blast furnace the 2nd coke charge charcoal
For burnt belt and feeding device (Zhen Dongshai ﹠amp; Feeding machine) operation
The 4th coke charge charcoal enters coke and concentrates bucket B
Coke is concentrated the bucket turnover panel to turn over to coke and is concentrated bucket A
The like
Ore system feed order and coke system class seemingly are not repeated herein.
Utilize lower pair of feeder system of concentrating bucket of blast furnace of the present utility model, setting by two concentrated buckets, can carry out very easily the conveying of material, raise the efficiency, and when running into one of them and concentrate bucket to break down, can in time concentrate bucket to carry out mass transport by another, improve efficient.
