[0002] Cement clinker preheater is one of the key equipment in cement production line. It is located before rotary kiln. Its main function is to use high temperature flue gas discharged from kiln tail to preheat raw meal that is about to enter rotary kiln. Preheater uses multi-stage cyclone and pipeline system to make raw meal fully contact with high temperature flue gas, realize heat exchange, increase preheating temperature of raw meal, reduce heat load of rotary kiln, thus improve thermal efficiency and output of the whole production line. At the same time, preheater can also effectively improve thermal performance of raw meal, create favorable conditions for subsequent calcination process.

[0003] The existing cement clinker preheater unloading device mostly unloads materials at one time, and lacks control over the unloading speed. When the unloading speed cannot be controlled, it may cause excessive accumulation of materials inside the preheater, especially blockage near the unloading port, which will not only hinder the normal entry of subsequent materials, but also affect the continuity and stability of the preheating process. The material accumulation will reduce the contact area between the high-temperature flue gas and the raw material in the preheater, thereby reducing the heat exchange efficiency. The clinker cannot fully absorb the heat in the flue gas, and the preheating effect is not ideal, which in turn affects the production efficiency of the subsequent calcination process.
