The box body is a cuboid composed of a left side plate 3, a top plate 2, a right side plate 11, a bottom plate 7, a box door and a rear back plate, a plate 12 is arranged at a position which is lower than an inner cavity of the box body, the inner cavity of the box body is divided into an upper cavity and a lower cavity by the plate 12, the upper cavity is a drying chamber 13, and the lower cavity is a gas distribution chamber 6; the air inlet pipe 5 is arranged on the left side plate 3 and is communicated with the air distribution chamber, and the air outlet pipe 1 is arranged on the top plate 2 and is communicated with the drying chamber 13; the top of the plate 12 is provided with a gas rising pipe 9 communicated with the gas distribution chamber 6, the gas rising pipe 9 is provided with gas distribution holes 8, the gas distribution holes 8 are square, the side length is gradually increased from bottom to top, and hot air in the gas distribution chamber 6 can be uniformly distributed at each part of the drying box.

As shown in fig. 2, the lower portion of the left side plate 3 is provided with three air inlets 5, the three air inlets 5 are uniformly distributed in the width direction of the drying box, and the temperature distribution of the hot air entering the air distribution chamber 6 is relatively uniform because the air inlets 5 are uniformly distributed in the width direction.

As shown in fig. 3, four exhaust pipes 1 are uniformly arranged on the top plate 2, so that the hot air flowing into the drying chamber can uniformly flow out of the drying box.

as shown in fig. 4, two rows of four rows of air-lift pipes 9 are uniformly arranged on the plate 12 along the length direction of the drying box, the air-lift pipes 9 are made of square steel, and the four side walls are all provided with air distribution holes 8 for uniformly distributing hot air.
