Cooling device for clinker in grate cooler

Abstract

The invention discloses a cooling device for clinker in a grate cooler. The cooling device comprises a grate cooler shell, wherein a blower nozzle is fixedly mounted on one side of the upper end of the grate cooler shell, an air inlet pipe is fixedly mounted at the upper end of the blower nozzle, a blower is fixedly mounted on the side, close to the blower nozzle, of the upper end of the grate cooler shell through a mounting seat, the air outlet of the blower is fixedly connected to the air inlet of the blower nozzle through an air inlet pipe, an air outlet is fixedly formed in the side, far away from the blower nozzle, of the upper end of the grate cooler shell, an air outlet pipe is fixedly mounted at the upper end of the air outlet, a plurality of heat conducting pipes are fixedly mounted in the middle of the upper end of the inner side of the grate cooler shell, and a plurality of heat conducting fin plates are fixedly mounted on the outer side surfaces of the heat conducting pipes. The cooling device is good in using effect, not only can cool clinker in the grater cooler by means of air cooling, but also can take away heat of the clinker in the grate cooler through a water flow quickly, and is good in cooling effect and high in cooling rate.

Description

technical field [0001] The invention relates to the technical field of grate cooler cooling, in particular to a cooling device for clinker in a grate cooler. Background technique [0002] The grate cooler is a commonly used cooler at present. After the clinker enters the cooler from the kiln, it is laid on the grate plate to form a material layer with a certain thickness, and the cold air blown in moves through the grate bed in a direction perpendicular to each other. The clinker can be quenched by the solid material layer, and the clinker can be quenched from 1300-1400°C to below 100°C. However, most of the currently used grate coolers are cooled by air cooling, and the cooling time takes several minutes. , or even tens of minutes, the cooling speed is slow, and when the heat-absorbed hot air flows out of the device, there is a lack of heat preservation measures, which causes a large amount of heat loss before the hot air is used, resulting in unnecessary waste.
