Description

Technical Field

[0001] The utility model relates to the technical field of grate coolers, in particular to a material discharging mechanism of a grate cooler. Background Art

[0002] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. At the same time, it provides hot air for rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system. With the rapid development of modern new dry process cement production technology and equipment, and the continuous improvement of cement clinker grate cooler technology, high-efficiency and reliable clinker grate cooler has become the key to ensure the production capacity of the system.

[0003] It is not convenient to disturb and stir the materials when discharging them in the hopper of the existing grate cooler. When large pieces of materials are added, it is easy to cause blockage in the material discharge, resulting in poor use effect and affecting the efficiency of material discharge. Moreover, during processing, since the temperature inside the grate cooler is relatively low, when materials are added, the cold air flow is easy to dissipate, affecting the cooling efficiency. Therefore, those skilled in the art provide a grate cooler discharging mechanism to solve the problems raised in the above background technology. Utility Model Content
