BACKGROUND

[0002] The belt conveyor is a long-span conveying equipment commonly used in factories, which can convey materials from one place to another place over a long distance. The materials carried by the belt conveyor are of various types, including materials with high temperature. When the belt conveyor conveys materials with high temperature, the high temperature of the materials will scorch the belt, which will test the quality and service life of the belt. In order to reduce the adverse effects of high-temperature materials on the belt, a spray pipe is arranged above the belt conveyor. The spray pipe sprays water curtain downward to cool the materials, thereby reducing the temperature of the materials and the scorching intensity on the belt. During the spraying process of the spray pipe, the water curtain sprayed by the spray pipe will disperse in the air due to the high height of the spray pipe. This results in that the materials on the belt conveyor cannot be cooled sufficiently, and the dispersed materials in the air will affect the construction work on site. Therefore, a cooling device is needed, which can efficiently cool the materials on the belt conveyor and prolong the service life of the belt conveyor. SUMMARY
