[0002] Sintered ore is a solid mineral composed of powdered iron ore and other substances, which is pre-treated and sintered at high temperature. The main components of sintered ore are iron oxides and other impurities. It is usually used in blast furnaces and direct reduction furnaces for steelmaking. It is one of the essential raw materials in the steelmaking process. Sintered ore fuel needs to be fed into the blast furnace for sintering by a feeding device.

[0003] At present, the sintering ore fuel feeding device can only feed one blast furnace, which means that multiple blast furnaces need to be equipped with multiple feeding devices, which increases the feeding cost and has poor practicality. Utility Model Content

[0004] The utility model aims to provide a combustion feeding device for sintered ore, which can feed multiple blast furnaces with one feeding device, thereby reducing the feeding cost, improving the practicality of the device and solving the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combustion feeding device for sintered ore, comprising a conveyor frame and a hopper, two conveyor rollers are symmetrically installed at both ends of the conveyor frame, a conveyor belt is connected between the two conveyor rollers, four supporting legs are installed in a rectangular array at the four corners of the bottom end of the conveyor frame, a circular frame is installed on the outside of the two right supporting legs, the hopper is sleeved in the circular frame, a feeding pipe is obliquely installed at the lower end of the side of the hopper, a sleeve is sleeved on the feeding pipe, a fixed block 1 is installed on the top of the feeding pipe, an electric telescopic rod is installed on the left side of the fixed block 1, the protruding end of the electric telescopic rod is fixed on the fixed block 2, the fixed block 2 is fixed on the sleeve, and a discharge nozzle is installed at the end of the sleeve.

[0006] Preferably, a row of auxiliary rollers is equidistantly installed between two conveying rollers at the bottom of the conveying frame, and the upper surface of the row of auxiliary rollers contacts the lower surface of the conveyor belt. By arranging a row of auxiliary rollers, the conveyor belt is supported.

[0007] Preferably, a mounting plate is installed at the left end of the front of the conveying frame, a conveying motor is installed on the top of the mounting plate, and the output shaft of the conveying motor is connected to the left conveying roller shaft through a flange. By setting the conveying motor, the conveyor belt can be driven to rotate.

[0008] Preferably, four steel balls are embedded and installed in a circular array around the edge surface of the circular frame. By arranging four steel balls, the hopper can be easily rotated.

[0009] Preferably, a support column is installed at the bottom of the feeding tube, and a universal wheel is installed at the bottom of the support column. By arranging the support column and the universal wheel, the feeding tube can be supported and moved easily.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] When the utility model is used, the electric telescopic rod first works to drive the sleeve to move forward and enter the feeding port of the middle blast furnace, and the sintered ore fuel is added from the left end of the conveying frame. The conveying motor works to drive the conveyor belt to rotate to convey the fuel. The fuel is conveyed and falls into the hopper, and then slides out of the hopper in turn, slides down the feeding pipe and the sleeve, and finally slides out of the discharge nozzle into the blast furnace. When the fuel is almost added, the conveying motor stops working until the dye in the hopper has all slid into the blast furnace. The feeding of the middle blast furnace is completed, the sleeve is retracted, and the discharge nozzle is manually moved to face the feeding ports of the blast furnaces on both sides. Then, the feeding steps of the middle blast furnace are repeated to feed the blast furnaces on both sides, thereby realizing that one feeding device can feed multiple blast furnaces, reducing the feeding cost and improving the practicability of the device.
