At this time, the electric push rod 310 extends to drive all the output plugs 315 to plug into the roller shaft plug-in slot 309 at the end of the first conveying roller 305. The second motor 312 and the second transmission belt 314 drive all the second transmission discs 313 so that the output plugs 315 drive the first conveying roller 305 to rotate in the same direction, thereby conveying the ceramic tile into the interior of the kiln body 1 for heating and drying;

[0031] The first conveying roller 305 is located in the high temperature environment inside the kiln body 1 for a long time, and the second conveying roller 306 is separated from the first conveying roller 305 by the heat insulation plate 307. The heat insulation plates 307 are tightly attached to each other, so that the second conveying roller 306 is inside the air supply channel, and the tile transportation is suspended periodically so that there are no tiles inside the kiln body 1. Then the electric push rod 310 contracts to separate the output plug 315 from the roller shaft plug-in slot 309 at the end of the first conveying roller 305, and the first motor 304 drives all the first transmission discs 302 to rotate through the first transmission belt 303, so that the first turntable 301 carries the first conveying roller 305, the second conveying roller 306 and the heat insulation plate 307 to rotate 180 degrees. , so that the first conveying roller 305 is located inside the air supply channel, and the second conveying roller 306 is turned over to the drying chamber, thereby exchanging the positions of the first conveying roller 305 and the second conveying roller 306, and then the electric push rod 310 extends to make the output plug 315 plug into the roller shaft plugging slot 309 at the end of the second conveying roller 306, thereby making the second conveying roller 306 rotate in the same direction through the second motor 312 to continue carrying the tiles for transportation, and fresh dry air circulates inside the air supply channel, and the first conveying roller 305 is cooled by the fresh dry air circulation and the heat of the first conveying roller 305 is recovered, and the fresh dry air after absorbing heat enters the collecting air box 205 along the second conveying pipe 4;

The moisture mixed with the hot air enters the condenser 203 along the heat conducting main pipe 202. The condenser 203 transfers the heat in the moisture to the refrigerant through the heat exchange principle, so that the water vapor in the moisture is quickly cooled and condensed into liquid water, thereby achieving effective separation of moisture and dry air. The separated dry air enters the collecting bellows 205 along the first transmission pipe 204, and the collecting bellows 205 also guides fresh dry air from the outside to mix with the separated dry gas and enter the preheating main pipe 206.

[0034] During the mixing and transmission of the dry gas and the fresh dry air in the preheating main pipe 206, the hot air containing moisture in the heat transfer main pipe 202 transfers its heat to the preheating main pipe 206.

At this time, the electric push rod 310 extends to drive all the output plugs 315 to plug into the roller shaft plug-in slot 309 at the end of the first conveying roller 305. The second motor 312 and the second transmission belt 314 drive all the second transmission discs 313 so that the output plugs 315 drive the first conveying roller 305 to rotate in the same direction, thereby conveying the ceramic tile into the interior of the kiln body 1 for heating and drying.

[0036] The first conveying roller 305 is located in the high temperature environment inside the kiln body 1 for a long time, and the second conveying roller 306 is separated from the first conveying roller 305 by the heat insulation plate 307. The heat insulation plates 307 are tightly attached to each other, so that the second conveying roller 306 is inside the air supply channel, and the tile transportation is suspended periodically so that there are no tiles inside the kiln body 1.
