The air cooling device comprises a cooling pipe, one end of the cooling pipe is fixedly connected with a first motor, the driving end of the first motor is fixedly connected with a spiral propeller, a ventilating duct is formed in the upper end of the cooling pipe, and the side, close to the upper end of the first motor, of the cooling pipe is fixedly connected with an intersection pipe; the upper end of the intersection pipe is fixedly connected with a speed reduction pipe, and the end, away from the intersection pipe, of the speed reduction pipe is fixedly connected with a feeding port. Through the arrangement of the speed reducing pipe, the flow rate of gypsum powder at the intersection pipe is limited, the gypsum powder is dispersed through air in the side face air spraying pipe, the dispersed air is conveniently in contact with the gypsum powder, and heat is absorbed through the air; and in order to prevent the temperature rise of the outer wall of the cooling pipe due to the influence of gypsum powder,
