Example Embodiment

[0023] Embodiments of the present invention are further described below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, a high-efficiency white cement clinker grate cooler includes a casing 1, a grate bed 2, a grate plate, an air chamber 3 and a cooling fan 4, the grate bed 2 is arranged in the casing 1, and the grate plate is arranged on the grate bed 2, the air chamber 3 is arranged below the grate bed 2 and is connected to the cooling fan 4, and also includes a first turning mechanism 5 and a second turning mechanism 6;

[0025] The top of the grate bed 2 is divided into a high temperature recovery zone 7 and a waste heat recovery zone 8. The shell 1 of the high temperature recovery zone 7 is provided with a high temperature clinker inlet 9 and a high temperature air outlet 10. The shell 1 of the waste heat recovery zone 8 is provided with a high temperature clinker inlet 9 and a high temperature air outlet 10. The low temperature air outle...

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...
