Description

Technical Field

[0001] The invention relates to the technical field of belt water spraying, in particular to a belt water spraying device. Background Art

[0002] After the red coke is pushed out of the coke oven, it is transported to the dry quenching coke by the dry quenching coke truck and cooled in the dry quenching furnace. After cooling down, the red coke is discharged from the bottom of the dry quenching furnace, weighed by a belt scale and falls onto the 101 belt, and then transferred to the 102 belt through the transfer warehouse, and finally falls onto the coke drying platform, and is transferred to the logistics center through the coke belt and coke belt group at the bottom of the coke drying platform. After the coke is dry quenched, it needs to be sprayed with water, and water needs to be sprayed on the 102 belt to reduce the temperature and dust of the belt conveyor. The belt rotates under the drive of the power wheel to transport the material.

[0003] In the prior art, when spraying water for cooling and dust reduction, water is generally sprayed directly onto the material on the upper surface of the belt through a nozzle. However, the material transported by the belt has a certain thickness, so that the material close to the belt cannot be in contact with the water in time for cooling.
