The heat exchanger 6 is installed on one side of the outside of the drying box body 1, and the other end of the spiral air duct 51 is connected to the heat exchanger 6. The turbulence fan 7 is installed on both sides of the inlet 11 of the drying box body 1.

[0033] In this embodiment, the drying box body 1 is placed in a suitable working position, ensuring that it is horizontal and stable. The circuit between the control console 3 and the drying box body 1 is connected, ensuring that the control console 3 can normally control the operation of the equipment.

[0035] Specifically, the conveying steel belt 23 is a porous conveying steel mesh, the bottom of the two end support frames 21 is fixed on the bottom of the drying box body 1, and the upper end of the two end support frames 21 is connected. The rotating shaft 22 is installed in the support frame 21 through a bearing.

[0036] In this embodiment, the support frames 21 are installed on both sides of the drying box body 1, and the bottom of the support frames 21 is fixed on the bottom of the drying box body 1, and the upper end is connected to each other.

The heating ring heats the air, the cooperation of the fan 4 and the turbulence fan 7 makes the hot air quickly and evenly contact the metal electroplated part 8, accelerates the evaporation speed of the moisture, and improves the drying efficiency.

[0048] In the embodiment, the heat exchanger 6 can effectively recover the waste heat of the discharged hot air in the drying process, and is used for preheating the cold air entering the drying box body 1, reduces the energy consumption of the heating element, and reduces the operation cost of the equipment.

[0049] In the embodiment, the air baffle 9 at the inlet 11 and the outlet 12 can block the external airflow from entering the inside of the drying box body 1, reduce the influence of the external environment on the temperature and airflow in the drying box, and ensure the stability of the drying environment.

[0050] Specifically, the slope design at the bottom of the air baffle 9 can guide the hot air to flow along the conveying direction, so that the hot air more concentratedly acts on the metal electroplated part 8, and the drying effect is further improved.
