In addition, the emission of alcohol into the saponification workshop also has certain potential safety hazards. Second, the mixing of marigold extract, alcohol and potassium hydroxide is only realized by the stirring device inside the saponification device, which has the problem of uneven mixing, affecting the saponification effect and efficiency of marigold extract. Therefore, it is an objective need to develop a marigold extract saponification device that can recover alcohol in a timely manner, is safe and environmentally friendly, and has high saponification efficiency.

[0021] The outer wall of the central pipe 10 is circumferentially provided with a plurality of vertical plates 16, the vertical plates 16 are arranged on the outer wall of the central pipe 10, and the heat exchange area of the cold water and alcohol vapor in the central pipe 10 can be greatly improved, and the heat exchange efficiency is improved.

[0022] A dehumidifier 17 is arranged in the exhaust pipe 8 above the cold water jacket 9, the dehumidifier 17 is a structure known in the art and is used for absorbing liquid in gas, in the utility model, alcohol vapor is discharged outwardly in the exhaust pipe 8, the cold water jacket 9 is used for absorbing heat in the alcohol vapor, so that the alcohol vapor is condensed into liquid and falls downward, and the recycling purpose is achieved, however, in actual use, a small amount of liquid alcohol is always discharged with other gas, causing waste of alcohol, in order to prevent this problem, the dehumidifier 17 is arranged, the dehumidifier 17 is used for absorbing alcohol liquid in gas, so that the alcohol liquid returns to the tank body 1, and waste of alcohol is further reduced.

[0023] A plurality of annular grooves 18 are formed on the outer wall of the exhaust pipe 8 in the cold water jacket 9. The annular grooves 18 are arranged on the outer wall of the exhaust pipe 8, which can greatly increase the heat exchange area of the outer wall of the exhaust pipe 8 and the cold water, and further improve the heat exchange efficiency.

[0024] The cold water jacket 9 is provided with a spiral plate 19. In use, the cold water is fed into the cold water jacket 9 from the cold water inlet 12, and the spiral plate 19 has a flow guiding effect on the cold water, guiding the cold water to flow spirally in the cold water jacket 9. The spiral plate 19 has two effects. One is that the spiral flow of the cold water can increase the flow process of the cold water in the cold water jacket 9, prolong the time of the cold water in the cold water jacket 9, and further improve the heat absorption efficiency of the cold water on the heat in the alcohol vapor. The other is that the spiral plate 19 can prevent the cold water from forming a flow dead zone in the cold water jacket 9, and improve the heat exchange efficiency of the cold water and the alcohol vapor.

[0025] The heater 20 is arranged on one side of the tank body 1. The hot water outlet 13 and the water outlet of the hot water jacket 3 are communicated with the water inlet of the heater 20 through pipelines. The water outlet of the heater 20 is communicated with the water inlet of the hot water jacket 3 through a pipeline. The heater 20 is a prior art device, which is used for heating the cold water to generate hot water. In the present application, the hot water discharged from the cold water jacket 9 has a high temperature and contains a large amount of heat due to the absorption of the heat in the alcohol vapor. After the hot water in the hot water jacket 3 heats the materials in the tank body 1, the hot water still contains a large amount of heat. The direct loss of the heat contained in the hot water will undoubtedly cause the waste of heat. In order to solve this problem, the heater 20 is arranged in the present application. The hot water in the cold water jacket 9 and the hot water jacket 3 is discharged into the heater 20, and then is fed into the hot water jacket 3 after being heated. On the one hand, the utilization rate of water resources is improved, and the waste of water resources is reduced. On the other hand, the loss of heat is reduced. The hot water is fed into the heater 20 to be heated, and only a small amount of heat is consumed to heat the hot water to the required temperature, thereby reducing the energy consumption for heating the hot water.

[0026] A plurality of discharge ports 21 are uniformly distributed on the bottom of the short cylinder 15 along the circumference. The ring plate 14, the short cylinder 15 and the side wall of the tank body 1 form an annular groove 23. The materials are first filled in the annular groove 23, and then overflow from the upper end of the short cylinder 15. After the saponification treatment is completed, a part of the materials will be retained in the annular groove 23. These materials cannot be discharged, which will cause the waste of materials. If the retention time of these materials is too long, the materials will be deteriorated, which will contaminate the materials for the next saponification operation. Therefore, it is necessary to discharge the materials in the annular groove 23. In order to achieve this purpose, the discharge ports 21 are arranged. When the device is normally operated, a small amount of materials is discharged from the discharge ports 21, which also plays a role in dispersing the materials. When the saponification is completed, the materials in the annular groove 23 can be discharged through the discharge ports 21, thereby preventing the waste of materials.

[0027] The double helix stirring paddle 22 is connected to the rotating shaft of the stirrer 2 through a connecting rod, and the annular groove 23 is formed between the short cylinder 15, the ring plate 14 and the side wall of the tank body 1. The stirring blade 24 is connected to the rotating shaft of the stirrer 2 through a cross bar, and the lower end of the stirring blade 24 extends into the bottom of the annular groove 23. The structure of the double helix stirring paddle 22 is a prior art, which is provided with two helix stirring paddles on the rotating shaft of the stirrer 2. The structure can make the materials such as extract, potassium hydroxide and alcohol be stirred thoroughly. It is verified by practice that, compared with the alcohol consumption when the ordinary stirring paddle is used, the alcohol consumption is reduced by half after the double helix stirring paddle 22 is used, and the stirring efficiency is greatly improved. In actual use, the distance between the lower end of the double helix stirring paddle 22 and the bottom of the tank body 1 can be 1-5 cm, so that the materials at the bottom of the tank body 1 can also be effectively stirred, and the stirring effect is further improved. In the present application, in order to improve the mixing efficiency of the materials, the circulation pipe 5 is provided, and the circulation pump is used to pump the materials at the bottom of the tank body 1 to the upper part of the tank body 1, and then falls into the annular groove 23. At this time, due to the arrangement of the stirring blade 24, the stirring blade 24 can also use the existing power source to stir and mix the materials in the annular groove 23 during the rotation of the rotating shaft of the stirrer 2, further improving the mixing efficiency of the materials, and making the materials be quickly and uniformly mixed.
