[0024] Example one, the bottom left and right sides of box 1 are all slidably connected with collecting box 15, two collecting boxes 15 are all located in the inside bottom side of cavity 8, the inside bottom side of box 1 is connected with two limit strips 14, two limit strips 14 are all located above cold air blower 5, the top of multiple support columns 13 is all connected with lifting lug;
[0025] Specifically, start warm air blower 2, blow hot air upward through middle communicating pipe 3 and air outlet, dry magnesium-carbon brick of different levels through warm air pipe 9, branch pipe 10 and warm air spout 11, the temperature in the inside of box 1 rises, through cold and heat exchange principle, the moisture in magnesium-carbon brick is evaporated, and moves upward along with hot air, at this time, the air hole on top cover 16 diffuses to both sides in the inside of box 1, so that water vapor is taken to cavity 8, thereby greatly reducing the water vapor in the inside of box 1, and further reducing the drying cycle of magnesium-carbon brick, through the heat of warm air spout 11 and cavity 8, magnesium-carbon brick is heated quickly and evenly, and the water vapor condensed in cavity 8 falls into collecting box 15, facilitating subsequent centralized processing.

[0028] Working principle:
[0029] In use, stack the magnesia-carbon bricks at the four corners above the storage tray 12, staggered from the cross-shaped support pipes 10, maintaining a certain distance. Then, connect the lifting device to the lugs on the support column 13, lowering them into the box 1 from the top side. The limiting strip 14 provides support and limits the movement, and the warm air pipe 9 is connected to the central connecting pipe 3. Continue stacking until the top support column 13 is close to the height of the box 1. Then, cover the top of the box 1 with the top cover 16 to complete the sealing operation. Start the heater 2, blowing hot air upwards through the central connecting pipe 3 and the air outlet. This hot air is then distributed to different layers of magnesia-carbon bricks via the warm air pipe 9, support pipes 10, and warm air nozzles 11 for drying. The internal temperature of the box 1 rises, and the heat exchange process is completed. In the process, the moisture inside the magnesia-carbon bricks evaporates and moves upward with the hot air. At this time, it diffuses to both sides of the chamber 1 through the vent on the top cover 16, so that the water vapor is carried into the cavity 8, thereby greatly reducing the water vapor inside the chamber 1 and thus reducing the drying cycle of the magnesia-carbon bricks. The heat from the hot air nozzle 11 and the cavity 8 makes the magnesia-carbon bricks heat up quickly and evenly. The water vapor condensed in the cavity 8 falls into the collection box 15 for subsequent centralized processing. After drying, the magnesia-carbon bricks can be quickly cooled down to room temperature by the combination of the cold air fan 5, the cold air pipe 6 and the cold air nozzle 7, shortening the cooling cycle of the magnesia-carbon bricks and thus shortening the drying cycle of the magnesia-carbon bricks. At this point, the entire process is completed.
