Description
Technical Field
The utility model relates to a feeding device of a blast furnace coal powder making system.
Background
In order to save energy, reduce consumption, reduce production cost and reduce waste, metallurgical enterprises need to add materials such as coke powder recovered in coking and iron-making production and transportation processes or dust removal powder of raw coal into a blast furnace, wherein the materials mainly comprise dry coke quenching powder and coking dust removal ash. At present, steel enterprises add the two materials into a blast furnace coal powder making system, and the two materials are ground and mixed and then enter a blast furnace together with the blast furnace coal powder through a blowing system for utilization, so that a large amount of cost can be saved every year.
The feeding device adopted by the existing iron and steel enterprise blast furnace pulverized coal making system generally comprises a coke powder tank truck, a pulverized coal bin, a dust remover, a humidifier and a coal feeder, and has the advantages of multiple system devices, large occupied space, high investment cost and long construction period. However, for the existing coal injection system, there is generally insufficient space or investment funds, and a set of complex system cannot be added to add additives in the process of pulverizing the pulverized coal of the blast furnace.

Furthermore, the powder feeding pipeline is provided with a control valve.
Further, the coal feeder is a fully-closed sealed coal feeder.
Has the advantages that:
(1) by adopting the feeding device of the utility model, the coal pulverizing system can realize the purpose of adding coke powder in the coal pulverizing system without adding extra complex equipment, the feeding device utilizes the suction and discharge tank car to pressurize and then beat additional materials into a coal machine discharge pipeline between a coal feeder and a coal grinding machine, the materials do not pass through the coal feeder, and the coal pulverizing system is a negative pressure system, so that the coal grinding machine is under negative pressure, and the additional materials can be smoothly brought into the coal grinding machine;

The utility model discloses the interpolation position with plus material sets up in coal machine ejection of compact pipeline 3, and is concrete, and coal machine ejection of compact pipeline 3 links to each other with suction and discharge tank car 6 through sending powder pipeline 5, and send powder pipeline 5 to be equipped with control flap 8.
During production of the blast furnace coal powder preparation system, raw coal in a raw coal bunker 1 is put into a feeding port at the top of a coal mill 4 through a coal feeder 2 and a coal mill discharge pipeline 3, and meanwhile, after additional materials (mainly coke powder and coking dust removal ash) can be pressurized through a suction and discharge tank car 6 and conveyed into the coal mill discharge pipeline 3 between the coal feeder 2 and the coal mill 4 through a powder conveying pipeline 7. Thereby achieving the purposes of waste utilization and production cost reduction. When no additional material is added, the suction and discharge tank car 6 stops working, the control valve 8 can be closed, and the normal production of the blast furnace coal powder making system is not influenced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
