[0002] Activated carbon is a very fine carbon particle with a large surface area and even smaller pores in the carbon particles - capillaries. This capillary has a strong adsorption capacity. Since the surface area of ​​the carbon particles is large, they can fully contact with the gas, so it is often used in breathing masks or filters. Its production process includes carbonization, activation, washing, drying, crushing and packaging. The traditional drying process is usually drying at room temperature, but in order to improve the drying efficiency, people gradually invented an activated carbon drying furnace to speed up the drying process.

[0003] The existing activated carbon drying furnace adds activated carbon through the material delivery port on the furnace cover, such as an activated carbon chain drying furnace body shown in application number: 202221857466.X. In order to improve the efficiency of one-time drying, a multi-layer conveying and drying platform device is usually used to place the activated carbon. In order to limit the movement range of the activated carbon, an inclined plate is usually used so that the upper layer of activated carbon can all fall into the lower layer; hot air is provided by a hot air supply device on one side of the furnace body, and the hot air spreads upward layer by layer through the conveying and drying platform device, so that the activated carbon can obtain sufficient heat to evaporate the moisture in the carbon, and the moisture floats upward layer by layer to the furnace cover and floats out through the air outlet on the side of the furnace cover.

[0004] Although this structure can increase the one-time drying output, after the hot air floats to the furnace cover, the heat will float out through the air outlet along with the water vapor, which causes a huge waste of heat energy. Utility Model Content
