[0002] Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the 18th century. Since the 21st century, although the value of coal is much less than before, after all, coal is still one of the indispensable energy sources for our human production and life for a long time. The supply security problem of coal is also the most important part of China's energy security.

[0003] The utility model with the patent number CN217303439U discloses a raw material drying device for a thermal power plant, including a stirring mechanism, including a device box, a motor arranged on the right side of the device box, a transmission shaft arranged on the output shaft of the motor, and stirring blades arranged on the surface of the transmission shaft and located inside the device box. The beneficial effect of the utility model is that by setting a DC fan, it is used to cooperate with the air inlet groove to transport external air into the device box, and at the same time, the air is heated by a heating mesh sheet, so as to be able to dry coal raw materials, and solve the problem that the coal raw materials will contain a large amount of moisture after mining, and if directly put into use, it will cause incomplete combustion.

[0004] When storing coal, a large amount of water is sprayed. Before processing, the coal will be dried. Although the device in the above patent improves the drying efficiency, the hot air after drying is directly discharged into the air. The dust and high temperature in the hot air are easy to cause environmental pollution and will also cause waste of heat resources. For this reason, we provide a raw material drying device for coal processing to solve the above problems. Content of the Utility Model
