The air inlet duct 100 communicates with the nozzle mechanism 200, and the return duct 600 communicates with the lower side of the mounting plate 300. The air nozzle mechanism 200 is internally provided with an air-uniformizing pore plate 202 and a ceramic honeycomb pore plate 205, the air-uniformizing pore plate 202 is positioned on the upper side of the ceramic honeycomb pore plate 205, and the pore diameter of the air-uniformizing pore plate 202 is larger than that of the ceramic honeycomb pore plate 205.

In the air nozzle device for drying in the above embodiment of the present application, because the air-uniformizing pore plate 202 and the ceramic honeycomb pore plate 205 are arranged inside the air nozzle mechanism 200, the hot air conveyed from the air inlet pipe 100 sequentially passes through the air-uniformizing pore plate 202 and the ceramic honeycomb pore plate 205 and then becomes more equally divided hot air to blow to the dried coating 400 on the lower side of the air nozzle mechanism 200, the structure improves the temperature uniformity of the hot air blowing to the dried coating 400, and uniform pressure is formed on the dried coating 400, which is helpful for improving the drying capability and product quality of the device.

Preferably, in one embodiment, the number of the adjusting plates 301 on the tuyere mechanism 200 is gradually reduced from the side close to the main air inlet pipe to the side far away from the main air inlet pipe. The more the air inlet amount of the air nozzle mechanism 200 closer to one side of the air inlet main body pipe is, the less the air inlet amount of the air nozzle mechanism 200 farther from one side of the air inlet main body pipe is, so that in order to ensure more consistent air inlet amount in the air nozzle mechanism, an adjusting plate 301 is arranged. Because the air inlet amount of the air nozzle mechanism 200 close to one side of the air inlet main body pipe is larger, the number of the adjusting plates 301 arranged on the air nozzle mechanism 200 is larger, so that the aperture of the communication part of the air nozzle mechanism 200 and the air inlet branch pipe is reduced.

As shown in fig. 1, the air inlet duct 100 includes a first air inlet branch duct 101, a second air inlet branch duct 102, and a third air inlet branch duct 103.

The drying process of the dried coating is a process in which hot air blown from the nozzle mechanism 200 continuously penetrates from the surface of the coating to the inside. The infrared heating body 501 of ceramic that sets up produces infrared radiant heating simultaneously, and its infrared wave directly permeates the nexine of coating for the material in the coating dissociates the coating surface fast, mixes with hot-blast formation mixed wind, discharges through return air pipe 600. The return duct 600 is provided with a fan (not shown) that can quickly discharge the mixed air. Tuyere mechanism 200 and ceramic infrared heating body 501 mutually support, even thick by dry coating 400, also can be with the nexine of coating and the surperficial not skinning on top layer when the surperficial quick drying, the drying performance of promotion tuyere device of great limit to improve by the product quality of dry coating.

When the hot air drying coating is blown out by the nozzle mechanism 200, the ceramic infrared heating body 501 can be heated by infrared radiation, but a certain amount of heat can be stored in the ceramic infrared heating body 501, and effective supplement can be performed between hot air heating and radiation heating. When heat does not need to be supplemented, the heat stored on the ceramic infrared heating body 501 is discharged together with the mixed air, so that the heat on the ceramic infrared heating body 501 is taken away in time, the heat is not stored, and the use safety of the ceramic infrared heating body 501 is improved.

In one embodiment, the inner side of the tuyere mechanism 200 further includes two shape fixing members 207, the two shape fixing members 207 are respectively located at the left and right sides inside the tuyere mechanism 200, and the shape fixing members 207 are used for contacting and fixing the uniform air hole plate 202 and the ceramic honeycomb hole plate 205.
