Abstract
The utility model relates to the field of metallurgical blast furnace feeding and particularly relates to a bell-less top charging device. The device comprises a feeding conveyor, charging buckets, a material level detecting device and a material distributing chute. The device is characterized in that two charging buckets are arranged side by side, the volume of each of the charging buckets is half of the volume of an ore batch or a coke batch, the feeding conveyor is a sealing-tape machine or a skip car, and the ore batch or the coke batch is divided into a front portion and a rear portion evenly on the feeding conveyor. Compared with the prior art, the bell-less top charging device has the advantages that a bell-less top charging method is changed, the ore batch or the coke batch are respectively loaded into the two charging buckets, for a blast furnace top reconstruction project, the volume of a blast furnace can be enlarged by above 30%, the effective volume of the blast furnace is increased and the blast furnace productivity is improved, and for a newly-built blast furnace project, the volume of the charging buckets is reduced by 50%, the height and the weight of a furnace top charging device are reduced and the investment is saved.
Description
Technical field
The utility model relates to metallurgy high furnace material loading field, particularly a kind of no bell top charging device.
Background technology
At present, both at home and abroad non-bell furnace top charging equipment all adopts pure jar structure, in criticize in 1 ore deposit or 1 coke (per) charge is all packed into the batch can, and when when filling with substance in blast furnace, the blast furnace of all packing into of the furnace charge in this batch can, and then load a batch of material.The weak point of this structure is that the batch can volume and weight is excessive, and the volume of blast furnace is restricted, and is unfavorable for that blast furnace carries product.
Summary of the invention
The purpose of the utility model provides a kind of no bell top charging device, overcomes the deficiency of prior art, under the prerequisite that satisfies blast furnace production, reduces the volume and weight of batch can, reduces cost, and increases the useful volume of blast furnace.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of no bell top charging device comprises material conveyer, batch can, material-level detecting device and distributor chute, and said batch can is two side by side, and the volume of batch can is that criticize or a coke (per) charge volume half the in an ore deposit.
Said upward material conveyer is conveyor drive or truck.
Criticize in a said ore deposit or a coke (per) charge evenly is divided into front and back two portions on last material conveyer.
Compared with prior art; The beneficial effect of the utility model is: the mode that 1) has changed no bell top charging; An ore deposit is criticized or a coke (per) charge is respectively charged in two batch cans,, can make furnace volume enlarge more than 30% for blast furnace furnace roof transformation project; Increase the useful volume of blast furnace, improve furnace processor.2) for newly-built blast furnace project, can batch can volume reducing 50% be reduced the height and the weight of top charging equipment, practice thrift investment.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure: the last material conveyer 2-first material section 3-of the 1-second material section 4-batch can one 5-batch can two 6-material-level detecting device 7-distributor chute 8-transmission rig 9-blast furnaces
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; It is a kind of no bell top charging device example structure synoptic diagram of the utility model; Batch can 1 is located at below the discharge port of material conveyer 1 side by side with batch can 25; Be provided with material-level detecting device 6 in batch can 1 and the batch can 25, the discharge port of batch can 1 and batch can 25 links to each other with distributor chute 7 through transmission rig 8, and the volume of batch can 1 and batch can 25 is that criticize or half of a coke (per) charge volume in an ore deposit.Last material conveyer 1 be conveyor drive or truck all can, general large blast furnace adopts conveyor drive more, small blast furnace adopts the truck charging more, when adopting the truck when filling with substance, generalized case is the 1-2 car material of packing in the batch can.
When the ore deposit groove is prepared burden; Criticize in ore deposit or a coke (per) charge on conveyor drive, evenly be divided into before and after two portions; The i.e. first material section 2 (Q1) and the second material section 3 (Q2); Last material conveyer 1 with these two independently material section be respectively charged in batch can 1 and the batch can 25, through distributor chute 7 furnace charge successive is successively packed in the blast furnace 9 again, accomplish packing into of a collection of furnace charge.
Claims (3)
1. a no bell top charging device comprises material conveyer, batch can, material-level detecting device and distributor chute, it is characterized in that, said batch can is two side by side, and the volume of batch can is that criticize or a coke (per) charge volume half the in an ore deposit.
2. a kind of no bell top charging device according to claim 1 is characterized in that, said upward material conveyer is conveyor drive or truck.
