A cooling device for cement rotary kiln

The utility model relates to a cooling arrangement specifically provides a cooling device for cement rotary kiln, aims at solving the problem that current cooler volume is too big and the thermal efficiency is low. Mesh for this reason, the utility model discloses a cooling device includes: the barrel, the connection is at the lower hopper of barrel below, the setting is at the crushing roller of barrel bottom, and set up the cold air duct on the upper portion of hopper under. The barrel is including the upper portion district section, intermediate zone section and the lower part district section that connect gradually, the cross section of upper portion and lower part district section is the square, the cross section length of side of upper portion district section is less than the cross section length of side of lower part district section, the intermediate zone section is the truncated pyramid shape. Owing to have above -mentioned structure, the utility model discloses can make dynamic cooling air all carry out counter current heat exchange through the bed of material of high temperature grog, can realize the purpose of high -efficient cooling high temperature grog. Simultaneously, because the barrel adopts the setting of undergauge formula for the grog of whereabouts can disperse more uniformly, and then improves heat exchange efficiency.
