Description

Technical Field

[0001] The utility model relates to the field of cement processing equipment, and in particular to a novel clinker silo bottom cooling device. Background Art

[0002] The clinker that has been calcined now needs to be loaded into the clinker silo. Generally, the height of the clinker silo is relatively high. The calcined clinker is transported to the clinker silo through the conveyor chain belt. At the same time, when the clinker that has been loaded is unloaded, it is necessary to unload the clinker onto the conveyor belt through the unloading port at the bottom of the clinker silo, and then transport the clinker out through the conveyor belt. The unloading port of the current clinker silo is generally equipped with a dust collector. The dust generated by unloading needs to be recovered by the dust collector, and the dust recovered by the dust collector falls onto the conveyor belt and is transported backward. When the clinker is discharged into the clinker silo, the temperature is relatively high, and the recovered gas from the dust collector at the bottom of the clinker silo is directly discharged into the clinker silo, which makes it difficult to dissipate heat in the silo, resulting in a relatively high temperature in the silo.
