In the process of drying 2-ethylanthraquinone, the air in the drying pipe 2 and the condensing pipe 3 can be circulated by turning on the gas guide fan 10, and the air flows upward in the drying pipe 2, so that the high-temperature water vapor evaporated in the drying pipe 2 can be brought to the upper end of the drying pipe 2 by the flowing air, and introduced into the condensing pipe 3 through the upper connecting seat 5, and cooled in the condensing pipe 3. Thus, the water in the high-temperature water vapor is condensed, and the condensed water is separated from the condensing pipe 3 to the inside of the water collecting tank 11 at the lower end of the condensing pipe 3 through the separation filter plate 17 between the condensing pipe 3 and the water collecting tank 11, and then filtered by the water vapor filter 9 and introduced into the drying pipe 2 at the lower end for circulation.

The right end of the material guide sealing groove 18 is rotatably connected to a material guide motor 21 through a rotating shaft, and the material guide motor 21 is fixedly connected to the outside of the right end of the hopper 6. In the process of 2-ethylanthraquinone passing through the hopper 6 and entering the interior of the upper connecting seat 5, the hopper 6 can introduce 2-ethylanthraquinone into the interior of the upper connecting seat 5 through the material guide sealing groove 18 at the lower end, and pass through the guide The material guide sealing roller 19 rotatably connected inside the material sealing groove 18 and the multiple material guide inner grooves 20 opened inside the material guide sealing roller 19 bring 2-ethylanthraquinone into the connecting seat 5, and the material guide inner grooves 20 are driven by the material guide motor 21 arranged on the lower side of the right end of the hopper 6.

At the same time, it ensures that the flow rate of the air flowing inside the drying tube 2 and the condenser tube 3 remains stable, so that the high-temperature water vapor inside the drying tube 2 can be taken away in time.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
