Embodiment Construction

[0016] See figure 1 and figure 2 The air duct sealing plate 1 used for the anti-blocking material on the ring cooler is provided with an air vent, and an air duct pipe 2 is arranged on the air vent. The plate 7 transitions to the horizontal plate 8, the inclination angle α of the inclined plate 7 is greater than or equal to the angle of repose of the material, the horizontal projection W of the inclined plate 7 is always smaller than the length E of the air duct, and the top plate 9 above is also inclined upward, and the wind The outermost side of the duct pipe 2 is made into a flange interface 10, which is connected with the air duct, and a material-retaining ventilation grid is added on the trolley side of the air duct pipe 2, and the material-retaining ventilation grid is composed of a vertical grid plate 3 and a distance bar 4 Composition, the height of the ventilation grid does not exceed the horizontal height of the bottom surface of the air duct pipe from top to botto...

Abstract

The present invention discloses a material blocking proof air duct sealing plate for a circular cooling machine. An air vent is arranged on the material blocking proof air duct sealing plate, an air duct pipe is arranged on the air vent, an inclined plate inclining upwards from the air vent at the bottom part of the air duct pipe has a transition to a horizontal plate, a stopping ventilation fenceis added to the air duct pipe at the side of a trolley. The large material is blocked by a ventilation fence during the discharging process after the material blocking proof air duct sealing plate ofthe present invention is adopted, and can not get into the air duct pipe, the small material also can not be heaved to the horizontal plate section of the air duct pipe because the low speed during rolling, but the small material drops on the inclined plate surface and glides into a material discharging chute. The present invention can not only meet ventilation requirements, but also prevent thematerial from blocking air vent to ensure the circular cooling machine normal operation.

Description

technical field [0001] The invention belongs to a device on a blast ring type cooler used for cooling sintered pellets in the metallurgical and mining industry, and in particular relates to a sealing plate used for an anti-blocking material air channel on the ring cooler. Background technique [0002] The trolley seal of the existing annular cooler is a cone seal, and the cold air is blown directly into the trolley from the lower bellows, and the sealing plates on both sides are blind plates, but the air duct sealing plate on the side of the new annular cooler is a joint between the trolley and the air duct. There are vents on the sealing plate at the connecting part of the system, and the wind from the air duct system can enter the trolley through the vents. [0003] After the cooling operation of the ring cooler, the trolley enters the unloading area and starts unloading. At this time, the annular air duct is sealed and blocked, and the air inlet of the sealing plate stop...
