Specifically, in the present embodiment, the air outlet of the circulation fan 20 is connected to the drying duct 10 through the air heater 21, that is, the air heater 21 is connected between the circulation fan 20 and the drying duct 10. Of course, the air flow in the drying duct 10 may be heated by a heating method of rotating the air without providing the air heater 21, for example, by providing a heating duct in a hot flue gas duct and heating by using the residual heat of the industrial flue gas.
The first screw feeder 30 is a commercially available screw feeder, and a discharge port thereof is connected to a pipe body of the drying pipe 10 at a position close to the gas heater 21 (if the gas heater 21 is not provided, the connection position thereof is close to the circulation fan 20). The first screw feeder 30 is mainly used to feed the material to be dried into the drying duct 10 and to prevent the material from flowing backward.
The discharge port of the hopper 40 is connected to the feed port of the first screw feeder 30 for receiving the material to be dried.
The first cyclone separator 50 may be a cyclone dust collector directly purchased from the market, and has an air outlet, an air inlet and a material outlet, preferably, the first cyclone separator 50 provided in this embodiment includes a first housing, the first housing has a first rotation cavity, a diameter of a lower portion of the first rotation cavity is gradually reduced from top to bottom, the air outlet of the first cyclone separator 50 is located at a top end of the first rotation cavity, the air inlet is located at a position where a side wall of the first rotation cavity is close to the top end of the first rotation cavity, and the material outlet is located at a bottom end of the first rotation cavity, that is, the first cyclone separator 50 provided in this embodiment improves a structure of the rotation cavity thereof on the basis of a conventional cyclone dust collector, so that an air flow entering the first rotation cavity is gradually narrowed, a distance of a material moving to a side wall surface of the first rotation cavity is gradually reduced, and a short circuit chance of the air flow is reduced, effectively improving the separation efficiency. The air inlet of the first cyclone separator 50 is connected to the end of the drying tube 10 not connected to the circulating fan 20, and is configured to receive the material air-dried by the drying tube 10, and separate the air-dried material from the material that is not completely air-dried, wherein the air-dried material flows out from the air outlet of the first cyclone separator 50 along with the air flow due to its relatively light weight, and the material that is not completely air-dried flows out from the material outlet of the first cyclone separator 50 under the action of gravity, but of course, due to the existence of the air flow, the above process is also substantially air-dried.
The second cyclone separator 60 may have the same structure as the first cyclone separator 60, or may have different structures, but it also has an air inlet, an air outlet and a material outlet. In this embodiment, the two structures are different, specifically, the second cyclone separator 60 in this embodiment includes a second housing, the second housing has a second rotation cavity, the diameter of the upper portion of the second rotation cavity gradually increases from the top toward the bottom, the diameter of the lower portion of the second rotation cavity gradually decreases from the top toward the bottom, the air outlet of the second cyclone separator 60 is located at the top of the second rotation cavity, the air inlet is located at the position where the sidewall of the second rotation cavity is close to the top of the second rotation cavity, and the air outlet is located at the bottom of the second rotation cavity, that is, the second cyclone separator 60 further improves the rotation cavity on the basis of the first cyclone separator 60, so that not only the first cyclone separator 60 has an effect, but also the distance between the central axis of the second rotation cavity and the sidewall can be gradually increased to reduce the possibility of the material short-circuiting to the air outlet, effectively improving the separation quality. The air inlet of the second cyclone separator 60 is connected with the air outlet of the first cyclone separator 50 and is used for receiving the materials which are air-dried, and because the kinetic energy of the air flow entering the second rotary cavity is relatively small, and the upper part of the second rotary cavity has a horn-shaped structure with gradually enlarged diameter, the materials are difficult to flow out from the air outlet of the second cyclone separator 50 along with the air flow, but flow out from the discharge hole of the second cyclone separator 50 under the action of gravity.

Preferably, the airflow air drying device provided by the embodiment further includes an air washing tank 82 and an air return pipe 83, wherein the air washing tank 82 has an air inlet and an air outlet, and an inner cavity of the air washing tank is filled with sulfuric acid or other drying agents capable of drying air for drying the airflow so as to be reused (the humidity of the airflow after the airflow is air-dried on the material is relatively high). Such a scrubber tank 82 is widely used in various types of gas drying equipment and will not be described in detail here. The air intake of scrubbing tank 82 is connected with the air outlet of knockout drum 80, and the one end of return air pipe 83 is connected with the gas outlet of scrubbing tank 82, and the other end is connected with circulating fan 20's air intake, because the air current temperature that flows out from knockout drum 80 still is great relatively, leads to circulating fan 20 used repeatedly through return air pipe 83 and can effectively reduce the heating burden. In addition, the body of the return air pipe 83 is provided with an air inlet hole, and the air inlet hole is provided with a one-way valve 84, so that air can be supplemented conveniently, and the outflow of hot air can be prevented.
