[0022] Embodiment 1

[0023] As Figures 1-4 shown, the present invention provides a device for improving the distillation efficiency, including an outer housing 1 and an inner housing 8. The inner housing 8 is arranged inside the outer housing 1. A top cover 6 is installed on the top of the outer housing 1. A first conveying pipe 2 is arranged in the cavity between the outer housing 1 and the inner housing 8. Both ends of the first conveying pipe 2 pass through one side of the outer housing 1. The upper end of the first conveying pipe 2 is fixedly communicated with a second conveying pipe 7. One end of the second conveying pipe 7 passes through one side of the top cover 6. One end of the second conveying pipe 7 is fixedly communicated with an annular conveying pipe 11. The annular conveying pipe 11 is fixedly connected to the inner wall of the inner housing 8. One side of the annular conveying pipe 11 is fixedly communicated with a third conveying pipe 10; an exhaust pipe 3 is fixedly communicated with one side of the top cover 6; a feed pipe 5 is installed on one side of the top cover 6, and the bottom of the inner housing 8 is fixedly communicated with a discharge pipe 9.

[0024] One end of the first conveying pipe 2 is externally connected to a steam generator to convey steam into the interior of the first conveying pipe 2. By the first conveying pipe 2 being arranged around in the cavity between the outer housing 1 and the inner housing 8, the flow path of the steam is extended. At the same time, the steam heats the materials inside the inner housing 8 more evenly. The other end of the first conveying pipe 2 is fixedly communicated with the second conveying pipe 7 to send the steam into the interior of the inner housing 8. The annular conveying pipe 11 is fixedly arranged inside the inner housing 8, and the third conveying pipe 10 extends into the interior of the inner housing 8, so that the steam can be sent into the interior of the inner housing 8. By washing the steam, the distillation effect of DAC can be improved.

[0025] Example Two

[0026] As Figure 1 , Figure 2 and Figure 4 shown, one side of the top cover 6 is fixedly connected with a driving motor 4. The output end of the driving motor 4 is fixedly connected with a first rotating shaft 16. One end of the first rotating shaft 16 passes through one side of the top cover 6. The outer part of the first rotating shaft 16 is rotationally connected with a second rotating shaft 20. A first stirring rod 15 is fixedly connected to the outer part of the first rotating shaft 16. Connecting plates 17 are fixedly connected to the outer parts of both the second rotating shaft 20 and the first rotating shaft 16. A connecting rod 18 is fixedly connected between the two connecting plates 17. A second stirring rod 19 is fixedly connected to the outer surface of the connecting rod 18. One end of the second rotating shaft 20 is fixedly connected with a second driven bevel gear 21. A fixed frame 14 is fixedly connected to the outer part of the second rotating shaft 20. One side of the fixed frame 14 is fixedly connected to one side of the top cover 6. A first driven bevel gear 13 is fixedly connected to the inner side of the fixed frame 14. One side of the first driven bevel gear 13 meshes with one side of the second driven bevel gear 21. The other side of the first driven bevel gear 13 meshes with a main bevel gear 12. The middle of the main bevel gear 12 is fixedly connected to the outer part of the first rotating shaft 16.

[0027] By arranging a feed pipe 5 on the top cover 6, materials can be fed into the inner shell 8. By arranging an air outlet pipe 3 on the top cover 6, the distilled DAC can be sent out. One end of the air outlet pipe 3 is connected to a condenser, which can condense the distilled gaseous DAC. During the distillation process, by the operation of the driving motor 4, the main bevel gear 12, the first rotating shaft 16 and the first stirring rod 15 are driven to rotate in sequence. A second rotating shaft 20 is rotationally arranged on the outer part of the first rotating shaft 16. The main bevel gear 12 meshes with the first driven bevel gear 13, and the first driven bevel gear 13 meshes with the second driven bevel gear 21. Thus, while the first rotating shaft 16 moves, the second rotating shaft 20 is driven to rotate, and the rotating directions of the first rotating shaft 16 and the second rotating shaft 20 are inconsistent. The second rotating shaft 20 drives the connecting plates 17, the connecting rod 18 and the second stirring rod 19 to move in sequence. Through the movement of the first stirring rod 15 and the second stirring rod 19, the mixing uniformity of the materials inside the inner shell 8 can be improved, which is convenient for improving the distillation efficiency of the materials.

[0028] Usage method and working principle of this device: During use, one end of the first conveying pipe 2 is externally connected to a steam generator to convey steam into the interior of the first conveying pipe 2. The other end of the first conveying pipe 2 is fixedly communicated with the second conveying pipe 7 to send the steam into the interior of the inner housing 8. The annular conveying pipe 11 is annularly fixed inside the inner housing 8, and the third conveying pipe 10 extends into the interior of the inner housing 8, so that the steam can be sent into the interior of the inner housing 8. By washing the steam, the distillation effect of DAC can be improved. The material is sent into the interior of the inner housing 8 through the feed pipe 5. One end of the air outlet pipe 3 is connected to a condenser to condense the distilled gaseous DAC. During the distillation process, the driving motor 4 works to drive the main bevel gear 12, the first rotating shaft 16 and the first stirring rod 15 to rotate in sequence. The second rotating shaft 20 is rotatably arranged outside the first rotating shaft 16, and the main bevel gear 12 meshes with the first driven bevel gear 13, and the first driven bevel gear 13 meshes with the second driven bevel gear 21, so that the second rotating shaft 20 is driven to rotate while the first rotating shaft 16 moves, and the rotation directions of the first rotating shaft 16 and the second rotating shaft 20 are inconsistent. The second rotating shaft 20 rotates to drive the connecting plate 17, the connecting rod 18 and the second stirring rod 19 to move in sequence to mix the material inside the inner housing 8.
