Embodiment Construction

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0030] The ring cooler is the cooling equipment for the hot sinter in the sintering process. Such as figure 1 and figure 2 As shown, the annular cooler includes: the annular cooler trolley 14, the annular cooler chassis wheel rail 13, the flange plate 10 of the annular cooler trolley (located above the annular cooler trolley 14), the lower bellows 6 of the trolley, The trolley guide rail platform 12 and the wheel rail 13 of the annular cooling machine platform are supported on the trolley guide rail platform 12, and the wheels of the annular cooling machine move on the wheel rail 13 of the annular cooling machine platform. in the attached figure 1 , it can be seen that the annular cooler is divided into three major areas: receiving area 1, cooling area 2, and unlo...

Abstract

The invention provides a lower sealing unit for a circular cooler. The lower sealing unit comprises sealed cavities; the sealed cavities located below a flange plate of a trolley of the circular cooler are located on two sides of the flange plate; the sealed cavities are hermetically connected between the flange plate and a guide rail platform; a gap between a lower air box of the circular cooler and the trolley of the circular cooler is sealed by the sealed cavities; wheel rails for the trolley are accommodated in the sealed cavities. Since the gap between the lower air box of the circular cooler and the trolley of the circular cooler is sealed by the sealed cavities, leakage rate of positive-pressure cooling air below the trolley is decreased, and power consumption of the circular cooler for ore cooling is lowered.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to the technology for the cooling process of sintered ore in iron and steel plants, in particular to a lower sealing device for an annular cooler. Background technique [0002] The sintering ring cooler is an important sinter cooling equipment in the sintering process. The hot ore at about 750°C falls into the sintering ring cooler trolley in the material receiving area, and is cooled by the positive pressure cooling air, and is driven by the ring cooler trolley. One week (40-60 minutes), go to the unloading area to unload the mineral material onto the belt. During the cooling process on the cooler, the positive pressure air is sent into the lower air box of the ring cooler by the blower, and then passes through the grate gap of the trolley, enters the trolley upwards, cools the hot mineral material in the car, and then the hot air reaches the collection cover Inside. Since the trolley r...
