Problems solved by technology

[0003] Through practice, the applicant in this case determined that the above-mentioned technical scheme can basically meet the actual needs, but also found the following deficiencies: in the process of cooling high-temperature mineral materials, especially sintered ore, because the sintered ore is not Stable, so that it is unstable and unevenly distributed in the heat exchange chamber, that is, the air resistance changes in each vertical direction. In the above technical scheme, the air resistance adjustment in each area cannot be changed in real time during the working process after it is set. It can stop and reset again, which cannot meet the needs of production well; at the same time, when the above technical solution is adopted, it is difficult to adjust the air resistance for the initial setting because the air resistance cannot be changed in real time

Embodiment 1

[0060]The vertical cooling kiln includes a feed device, a cooling kiln body, a discharge device, an air inlet device, an air outlet device and a control system; the cooling kiln body includes a feed bin 2, a heat exchange bin 11 and a material transfer pipe 4 , the feeding bin 2 is located above the heat exchanging bin 11, and at least one feed pipe 4 is located between the feeding bin 2 and the heat exchanging bin 11 and communicated; the bottom of the feeding bin 2 and the heat exchanging bin 11 The roof shares a partition, or the two are arranged independently; the heat exchange chamber 11 is a cylinder structure mainly surrounded by the roof 7 and the kiln wall 12, and the inner cavity of the heat exchange chamber 11 is the kiln chamber 13; At least one feeding port 1 is arranged on the top of the warehouse 2; the material transfer pipe 4 extends into the heat exchange chamber 11 for a predetermined length; during operation, the high-temperature mineral material passes thro...

Embodiment 2

[0069] It is basically the same as Embodiment 1, except that the hot ore air distribution plate 9 is profilingly arranged according to the concave-convex shape of the hot ore top surface 10, and any point on the lower surface of the hot ore air distribution board 9 is in contact with the hot ore top surface 10. The vertical distance is that H is less than 200 centimeters, preferably H is less than 50 centimeters, more preferably H is less than 3 centimeters; or the inclination angle W of the lower surface of the hot ore uniform air plate 9 is not less than the angle A between the generatrix of the hot ore top surface 10 and the horizontal plane , that is, W is not less than the angle of repose A of the high-temperature mineral material; the lower surface of the hot ore uniform air plate 9 can be lower than the hot ore top surface 10 when the hot ore uniform air plate 9 is not set; the hot ore uniform air plate 9 and The kiln wall 12 and the feed pipe 4 are all sealed and connec...

Embodiment 3

[0071] It is basically the same as Embodiment 1 or 2, the difference is that the air regulating component of the JY1 type uniform ventilation device adopts one or a combination of the following structures:

[0072] JY101: The air adjustment assembly includes a movable air adjustment plate 16 and an actuator; the movable air adjustment plate 16 is a plate-shaped or ring-shaped structure, which is arranged on the outside of the material transfer pipe 4, above the air outlet 8, and is connected with the air outlet 8. The actuator is connected; during work, under the action of the actuator, the movable air regulating plate 16 moves up and down to change the ventilation area of ​​the air outlet 8;

[0073] JY102: The air adjustment assembly includes a movable air adjustment plate 16 and an actuator; the movable air adjustment plate 16 is a plate-shaped or ring-shaped structure, which is arranged on the outside of the material transfer pipe 4, below the air outlet 8, and is connected...
