Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grate coolers, in particular to a device for strengthening the supporting strength of an air-filled beam of a grate cooler. Background Art
[0002] The cooling fan at the grate tail enters the air beam through the ventilation duct. The air beam is connected to the seam of the plate, and there are many small holes on the seam. The gas dissipates through the small holes to buffer the high-temperature molten clinker coming from the kiln head and play a role in initial cooling.
[0003] Cement raw materials need to go through processes such as water evaporation, clay raw material dehydration, carbonate decomposition, solid phase reaction, firing reaction and cooling before they can form powdered or granular cement clinker. After the clinker is fired, it enters the clinker transportation and cooling process. The grate cooler is used for the transportation, uniform cooling and crushing of the clinker. The high-temperature hot air used to cool the clinker enters the rotary kiln and preheater to provide the high-temperature air required for coal powder combustion. Therefore, the normal operation of the grate cooler plays a vital role in the quality and output of the clinker. If the gap between the grate plates of the grate cooler is not within the specified range, it will easily cause the quality of the clinker to decline if it is not handled in time. The firing system will increase energy consumption due to low heat recovery efficiency. The poor clinker cooling effect and high clinker temperature will pose a great hidden danger to the operation of the equipment in the next process. Utility Model Content
