Description

Technical Field

[0001] The present application relates to the technical field of cooling devices, and in particular to a cement clinker cooling device. Background Art

[0002] The core step of cement production is calcination through a rotary kiln, burning raw materials such as limestone, clay, and iron raw materials until they are partially or completely melted. During the firing process, the temperature of the clinker can reach 1300°C to complete the required chemical reaction. After calcination, the cement clinker needs to be cooled quickly to avoid the decomposition of C3S, so as to obtain a stable crystalline product.

[0003] The prior art CN220034348U discloses a cement clinker cooler that can cool quickly. The servo motor drives the transmission rod to rotate, and the transmission rod drives the threaded conveying rod to rotate, which plays a role in evenly turning and transporting the cement clinker. The coolant is conveyed to the water pipe through the conveying box and the water pump, and the coolant is conveyed to the cooling pipe through the water pipe, which plays a role in preliminary cooling of the cement clinker. Through the setting of the exhaust fan, the exhaust fan rotates to discharge the internal hot air, thereby playing a role in secondary cooling of the cement clinker, thereby improving the cooling efficiency of the device.
