[0094] During use, cement clinker enters the cooling chamber 5 and falls on the first grate bed 11. At the same time, by starting the first fan 21, the second fan 22, the third fan 23, and the fourth fan 24, the cooling air generated by the first fan 21 is blown toward the first grate bed 11 through the first air supply duct 51 to cool the cement clinker on the first grate bed 11. The second fan 22 blows the cooling air generated by the second fan 22 toward the first grate bed 11 through the second air supply duct 52, and the air outlet of the second air supply duct 52 is in contact with the grate plate inside the first grate bed 11. The moving directions are consistent, and the hot air after cooling in the cooling chamber 5 is discharged out of the cooling chamber 5, and the fourth fan 24 can stabilize the wind pressure in the cooling chamber 5, so as to improve the cooling efficiency of the cement clinker, and when the cement clinker is transported through the second grate bed 12, the third fan 23 is used to inflate the air beams 124 and the air grate plates 125 in the second grate bed 12, so that the cement clinker is bumped up and down on the second grate bed 12, so that the cement clinker can be fully cooled by the cold air in the cooling chamber 5.

[0095] The first grate bed 11, the first fan 21, the second fan 22, the third fan 23 and the fourth fan 24 used in the utility model are all existing technologies and can be directly purchased and used on the market. Therefore, the structure, circuit and principle of the first grate bed 11, the first fan 21, the second fan 22, the third fan 23 and the fourth fan 24 are not described in detail here.
