Description

Technical Field

[0001] The utility model relates to the technical field of vertical furnace equipment for sintering pellets, in particular to a vertical furnace straight funnel. Background Art

[0002] A direct reduction ironmaking method that uses high-temperature reducing gas or solid reducing agent to reduce iron ore in a vertical furnace. This method initially used charcoal to make reducing gas. Later, due to economic reasons, coke was used to make gas. In the 1960s, with the development of the oil and natural gas industry, the vertical furnace direct reduction method using natural gas as energy source flourished.

[0003] The reaction conditions of the vertical furnace are similar to those of the indirect reduction zone at the top of the blast furnace. The reduced direct reduced iron is cooled by cooling water in the cooling zone at the bottom of the vertical furnace. The cold direct reduced iron is discharged from the furnace through the discharge mechanism.

[0004] The cooling effect of the vertical furnace straight funnel currently used is poor. After a period of use, the inner cooling wall is worn through, and then the cooked balls enter the cooling water tank, and the cooling water tank is also damaged due to the scouring of the cooked balls in the furnace. Because the furnace is under positive pressure, the cooked balls will spray out from the damaged part of the water tank during normal production, causing safety impacts on other surrounding equipment and operators; when the vertical furnace is not in production smoothly, the cooked balls in the furnace will form lumps, which are easy to accumulate at the connection between the straight funnel and the inclined funnel, blocking the normal discharge of the straight funnel; there is no dredging hole above the straight funnel, and the dredging hole temporarily opened during the production process will be difficult to seal after the dredging is completed due to the overflow of cooked balls.

[0005] Therefore, it is necessary to design a device to solve the above technical problems. Utility Model Content
