High-efficiency white cement clinker grate cooler

Abstract

The invention discloses a high-efficiency white cement clinker grate cooler. The grate cooler comprises a first material turnover mechanism and a second material turnover mechanism. The first materialturnover mechanism and the second material turnover mechanism are both located in a waste heat recovery area and above a grate plate. The first material turnover mechanism comprises two first coolingrollers. Each first cooling roller is provided with turning blades. The second material turnover mechanism comprises a second cooling roller. The second cooling roller is provided with curved turningblocks. The first cooling rollers and the second cooling roller are all connected with corresponding to rotating driving devices and water supply devices. According to the high-efficiency white cement clinker grate cooler, the first cooling rollers of the first material turnover mechanism can turn over clinkers at the two ends of a grate bed and throw the clinkers to the middle; when the clinkersare continuously pushed to a cooled clinker outlet, so that coarse particles and fine particles in the clinkers are distributed more uniformly on the grate bed, and the Red River phenomenon is avoided; the second cooling roller of the second material turnover mechanism can turn over and stir the clinkers, so that all parts of the clinkers are cooled more uniformly.

Description

technical field [0001] The invention belongs to the technical field of grate coolers for white cement clinker production, and in particular relates to an efficient white cement clinker grate cooler. Background technique [0002] White cement, the abbreviation of white Portland cement, is made of calcium silicate as the main component by burning raw materials with appropriate ingredients until they are partially melted. The clinker with low iron content is added with an appropriate amount of gypsum, and the white water is made by fine grinding. Rigid gelling material. The grate cooler is needed in the production of white cement. The grate cooler is an important main equipment in the clinker firing system of a cement plant. Its main function is to cool and transport the cement clinker, and at the same time provide Hot air is the main equipment for heat recovery in the firing system. [0003] The existing grate cooler is prone to the red river phenomenon when transporting whi...

AI Technical Summary

Problems solved by technology

[0003] The existing grate cooler is prone to the red river phenomenon when transporting white cement clinker, that is, the coarse grain clinker and the fine grain clinker are respectively distributed at both ends of the grate bed, and the end of the fine grain clinker is closed due to the small amount of cold air passing through. Rapid cooling is not obtained, thereby reducing the quality of the finished clinker and the recovered heat; and the clinker is accumulated on the grate plate to a certain thickness, so that each part of the clinker cannot be cooled uniformly
