Description

Technical Field

[0001] The utility model relates to the technical field of cement cooling, in particular to a cement cooler. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. In the cement production process, the temperature of the calcined cement clinker is high and it needs to be cooled before leaving the factory. This requires the use of a cement cooler. The main function of the cement cooler is to cool the high-temperature cement clinker through the internal cooling pipe and reduce the temperature to an appropriate range to ensure that it can enter the clinker mill smoothly without affecting the quality of the clinker.

[0003] In the prior art, there is a cooler for cement production disclosed in announcement number CN217330745U, which specifically relates to the technical field of cement production. When in use, the staff first connects the feeding pipe with the external cement conveying pipe, and the cement flows into the tank body through the feeding pipe and the disc, and uses a motor to drive the gear to rotate. The gear drives the rotating shaft and the annular rack to rotate at the same time. When the rotating shaft rotates, the chain and two sprockets drive the stirring shaft to rotate together. The rotation direction of the stirring shaft is opposite to the rotation direction of the tank body. The multiple stirring rods on the stirring shaft stir the cement, and at the same time, the spiral blades convey the cement at the bottom of the tank body to the top of the tank body to realize the circulation of the cement. The annular rack drives the tank body to rotate on the workbench, so that the cement in the tank body is evenly dispersed, and the speed of heat dissipation is increased. The coolant in the water cavity of the tank body absorbs the heat, and then the refrigeration plate is used to absorb the heat in the coolant and discharge it to the outside of the tank body, which has a rapid cooling effect and greatly improves the cooling effect of the cement.

[0004] The above patent utilizes refrigeration plates to absorb the heat in the coolant to achieve a rapid cooling effect. However, in actual use, since the inner wall of the tank is easily covered by cement clinker, the cooling speed of the cement clinker is inconsistent, resulting in insufficient and insufficient cooling, unsatisfactory cooling effect, reduced cooling efficiency, and affecting its use. Therefore, how to design a cement cooler has become a problem that we currently need to solve. Utility Model Content
