Description

Technical Field

[0002] Chinese Patent CN117419574A discloses a convection type ring cooler, which is composed of a sealing device, a hot air recovery device, a rotary body, a transmission device, an air inlet system, a discharging device, etc. The hot sintered cake enters the rotary body after being crushed by a single-tooth roll. As the rotary body moves at a constant speed, the hot sintered cake is evenly distributed into the body. The rotary body is an annular structure welded by a steel structure and rotates around a fixed center. An exhaust fan draws cold air and recycled hot air into the rotary body. Under the action of negative pressure, the cold air passes through the hot sintered ore layer from bottom to top and exchanges heat with it. The material at the bottom of the sintered ore layer is the first to be cooled and is discharged through the discharging device. Thus, the rotatable vertical cooler completes the whole process of uniform feeding and cooling of hot sintered ore. Since the cooling air enters the cooler from the side, it will inevitably cause the situation that the hot ore in the middle of the cooler receives less air volume, and in severe cases, the phenomenon of red ore in the middle will occur, as shown in Figure 1 the shaded part in; the red ore after unloading will burn the ore conveying belt.
