Description

Blast Furnace Feeding Equipment

technical field

The utility model relates to the technical field of metallurgy, in particular to a blast furnace charging device.

Background technique

During the blast furnace loading operation, various materials are imported into the conveyor belt through the coke bin and ore bin according to a certain ratio, and then transported by the belt to the blast furnace for production. Due to the large amount of feeding materials, individual materials are easy to be blocked in coke bins, mine bins and belts, etc., resulting in insufficient feeding of individual materials; at the same time, the difference in belt speed will also change the ratio of feeding materials, making the reaction in the blast furnace proceed. If it is not thorough, the consumption of materials will be large, the output of products will decrease, and the quality of products will be seriously affected.

Utility model content

The purpose of the utility model is to provide a blast furnace charging device with reliable operation and accurate charging.

The technical scheme that the utility model solves its technical problem adopts is:

A blast furnace feeding equipment, comprising a material feeding mechanism and a material distribution mechanism, the material feeding mechanism includes an ore bin, a coke bin, an ore output belt, a coke output belt and a material feeding main belt; the material distribution mechanism includes a furnace top hopper , material tank I, material tank II, material distribution flap, upper sealing valve, lower sealing valve and distributor, a weighing hopper and a vibrating feeder are installed between the ore bin and the ore output belt; coke bin and coke There is a weighing bucket and a vibrating feeder between the output belts.

The ore output belt, the coke output belt and the material feeding main belt are respectively provided with material flow detection points.

The utility model installs a weighing hopper and a vibrating feeder under the ore bin and the coke bin of the feeding conveying mechanism, and adds material flow detection points on the ore output belt, the coke output belt and the main feeding belt. The vibrating feeder makes the material conveying more uniform, and the material flow detection point can monitor the speed and conveying volume of the ore output belt and the coke output belt. Proper adjustment of the weighing hopper and belt speed can achieve precise batching, thereby improving output and quality.

Detailed ways

As shown in the figure, a blast furnace feeding equipment includes a feeding conveying mechanism and a material distributing mechanism. The feeding conveying mechanism includes an ore bin 1, a coke bin 2, an ore output belt 5, a coke output belt 6 and a main feeding belt 7. The material distributing mechanism includes a furnace top hopper 8, a material tank I9, a material tank II10, a distribution flap 13, an upper sealing valve 14, a lower sealing valve 15 and a distributor 16, which is characterized in that the ore bin 1 is connected to the mine A weighing hopper 4 and a vibrating feeder 3 are arranged between the output belt 5; a weighing hopper 4 and a vibrating feeder 3 are arranged between the coke bin 2 and the coke output belt 6. The ore output belt 5, the coke output belt 6 and the main feeding belt 7 are respectively provided with material flow detection points 12.

When in use, the material transportation of the ore output belt 5, the coke output belt 6 and the main material feeding belt 7 is detected through the material flow detection point 12. When the feeding ratio changes, the weighing weight of the weighing bucket 4 is properly adjusted. , or adjust the matching speed of the ore output belt 5 and the coke output belt 6, so that the feeding ratio meets the production requirements.
