[0016] See also Figure 1-4 The present embodiment is a cooling device for a dry quenching coke transport belt 1, comprising a spray device and a cold air device. The spray device comprises a cold water pipe A5 arranged on the inner side of the belt 1 and a cold water pipe B6 arranged below the belt 1. The cold water pipe A5 and the cold water pipe B6 are arranged along the conveying direction of the belt 1. The tops of the cold water pipes A5 and B6 are provided with a plurality of water spray holes along the length direction, and the water spray holes face the belt 1 above. The cold water pipes A5 and B6 are connected to a main water pipe 4 together, and one end of the main water pipe 4 is connected to a water source. The cold air device is arranged on the inner side of the belt 1 and close to the driving end roller 2.
[0017] The utility model uses a cooling fan 3 to cool the roller 2 near the driving end, in order to prevent the friction between the roller 2 and the belt 1 from being reduced due to spraying water, thereby causing slipping. Therefore, a cooling fan 3 is used here to cool the belt 1 instead of a spraying device, and cooling water is sprayed by a spraying device at other locations to cool the belt 1. Preferably, the cooling device uses a cooling fan 3.
[0018] Preferably, a plurality of exhaust devices are provided along the upper side of the belt 1, and the exhaust devices are used to extract the water vapor generated by the spraying. Each exhaust device includes an air collecting hood 7, and one end of the air collecting hood 7 is connected to the exhaust fan through a pipeline. The exhaust fan forms a negative pressure in the pipeline of the air collecting hood 7, thereby extracting the water vapor in the space and discharging it to the outside.
[0019] Preferably, a drainage ditch is provided under the belt 1, and the drainage ditch is arranged along the conveying direction of the belt 1, so that water on the belt 1 falls into the drainage ditch and is collected. The collected water is purified and filtered through sedimentation and then reused to cool the belt 1, thereby reducing the cost of water use.
[0020] Preferably, the belt 1 is arranged obliquely, and the cold air device is arranged at the upper roller 2, so that the water sprayed onto the belt 1 by the spray device flows toward the lower end due to gravity.
[0021] Preferably, the water spray hole is a conical hole, and the diameter of the water spray hole gradually increases from the inside of the cold water pipe to the outside, so as to increase the range of cooling water spraying.
