[0018] By adopting the above scheme, the ethanol mixture is injected into the containing box 3 from the liquid inlet 31, and then the heating box 1 is filled with water, and the external power supply is connected. The heater starts heating and uses a water bath for heating. The water bath heating has the characteristics of stable heating and uniform heating. The heated ethanol gas will adhere to the upper surface of the inner wall of the collecting box 4.

[0019] like Figures 2 to 3 As shown, a liquid collecting box 4 is arranged on the top of the containing box 3, and the top surface of the liquid collecting box 4 is an arc-shaped plate, and the two sides of the liquid collecting box 4 are inclined inwardly. A rotating mechanism is installed in the middle of the bottom of the liquid collecting box 4, and the rotating mechanism includes a rotating shaft 10 rotatably connected to the inside of the liquid collecting box 4, and the rotating shaft 10 passes through the liquid collecting box 4 and is perpendicular to the front of the liquid collecting box 4. The drain plate 7 is fixedly connected to the rotating shaft 10, and the top of the drain plate 7 is in contact with the inner wall of the top surface of the liquid collecting box 4. Axes are arranged on both sides of the middle of the rotating shaft 10, and the rotating shaft 10 is rotatably connected to a U-shaped rotating frame 11 through the axes on both sides. A hinged bent plate 12 is provided below the U-shaped rotating frame 11, and the bent plate 12 is an obtuse-angle bent plate, and the other end of the bent plate 12 is provided with a connecting shaft 1 perpendicular to it. 3. A motor 17 is fixed on the outer wall of the accommodating box 3, and the output shaft of the motor 17 passes through the accommodating box 3. A second bevel gear 16 is fixedly connected to the output shaft of the motor 17. A fixing frame 14 is installed on the inner wall of the accommodating box 3. A connecting shaft 13 is rotatably provided on the upper surface of the fixing frame 14. The upper end of the connecting shaft 13 is fixedly connected to the bent plate 12, and the lower end of the connecting shaft 13 is fixedly connected to the first bevel gear 15. The first bevel gear 15 is meshed with the second bevel gear 16. Baffles 9 are provided at the bottom of both sides of the inside of the collecting box 4. A groove 8 is provided above the baffle 9 and at the joint with the two side surfaces. The groove 8 is an inverted isosceles trapezoid, and the upper base of the trapezoid is larger than the lower base. The bottom of the groove 8 is connected to a drainage pipe 5, and the lower end of the drainage pipe 5 is inclined to both sides.

[0020] By adopting the above scheme, the motor 17 is started, and the motor 17 drives the second bevel gear 16 to rotate, thereby driving the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 can drive the bent plate 12 to rotate. One end of the bent plate 12 is rotatably connected to the fixed frame 14, and the other end of the bent plate 12 drives the U-shaped rotating frame 11 to rotate. The U-shaped rotating frame 11 drives the rotating shaft 10 to swing, so that the rotating shaft 10 drives the drainage plate 7 to swing. The liquid attached to the upper surface of the collecting box 4 is drained to the side walls on both sides of the collecting box 4 under the action of the swinging of the drainage plate 7, flows into the groove 8 set on the side wall, and finally flows into the drainage pipe 5.

The plurality of cooling plates 61 are staggered on the inner wall of the cooling box 6, and the cooling plates 61 are arranged to be inclined downward. A liquid outlet 62 is arranged at the bottom of the cooling box 6, and the bottom of the cooling box 6 and the bottom of the heating box 1 are located on the same horizontal plane.

[0022] By adopting the above scheme, the ethanol liquid flowing out of the drainage tube 5 enters the cooling box 6, first falls on the uppermost cooling plate 61, and flows downward along the cooling plate 61 in an alternating manner. In this process, the cooling effect is achieved without consuming additional reagents and energy. The structure is simple and practical.

[0023] The working principle of the utility model is as follows: liquid to be heated is injected from the liquid inlet 31, water is filled in the heating box 1, the heating box 1 is started, and the heated ethanol gas floats to the upper surface of the liquid collecting box 4. The boiling point of ethanol is 78.3 degrees. The heating box 1 controls the temperature. When the ethanol temperature reaches 78.3 degrees, the ethanol volatilizes, the motor 17 is started, and the motor 17 drives the rotating mechanism to rotate, thereby driving the drainage plate 7 to swing. The drainage plate 7 guides the liquid on the upper surface of the liquid collecting box 4 to the inner walls on both sides of the liquid collecting box 4, and then flows into the groove 8, flows into the cooling box 6 through the drainage pipe 5, and achieves the cooling effect through multiple cooling plates 61. Finally, it is discharged from the liquid outlet 62, which can convert ethanol into anhydrous ethanol and improve the purity of ethanol.
