Description

Technical Field

[0001] This utility model relates to the field of alcohol production technology, specifically to a distillation apparatus for alcohol production. Background Technology

[0002] Alcohol distillation is the core process of ethanol purification through temperature and concentration differences [1]. This technology focuses on the safety design of alcohol distillation workshops, emphasizing fire prevention and explosion protection measures, equipment sealing and ventilation system engineering specifications. Based on data such as ignition point and explosion limit, a hazard assessment system for alcohol and its impurities has been established. Its distillation process follows the temperature law, concentration law and purification law, utilizes the boiling point difference to achieve gas phase enrichment effect, and finally completes the removal of impurities through a multi-stage separation device.

[0003] Temperature control is crucial in alcohol distillation. The optimal distillation temperature needs to be controlled between 77°C and 79°C for efficient distillation while avoiding the introduction of water vapor. Direct heating makes temperature control inconvenient and can affect the purity of the distillation. Some existing methods use stirring to assist internal temperature mixing, but the liquid inside the tank is constantly subjected to centrifugal force, which still leads to a temperature difference between the inside and outside. Therefore, we propose a distillation device for alcohol production. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a distillation apparatus for alcohol production, including a heating box 1, a water bath 2 fixedly installed above the heating box 1, the water bath 2 serving to heat the heat-conducting flow tube 3, and the top of the water bath 2 extending upwards above the reflux pipe 12, facilitating the exchange of external temperature and rapid water addition. An insulation sleeve 5 supports the heating box 1, providing insulation between the reflux evaporator 4 and the external environment, preventing temperature exchange from affecting the alcohol temperature and distillation efficiency. The reflux evaporator 4 is fixedly installed inside the insulation sleeve 5, and the heat-conducting flow tube 3 is fixedly installed inside the water bath 2. The horizontal cross-section of the reflux evaporator 4 is U-shaped. The front and rear ends of the heat-conducting flow tube 3 are fixedly connected to the reflux evaporator 4, and the inner cavity of the heat-conducting flow tube 3 communicates with the inner cavity of the reflux evaporator 4. The reflux evaporator 4 enables alcohol distillation, and the heat-conducting flow tube 3 assists in the flow of alcohol, effectively ensuring stable and uniform temperature conduction.

[0021] The inner cavity of the reflux evaporator 4 is fitted with a rotating shaft 6, and the outside of the rotating shaft 6 is fitted with a spiral blade 7. The outside of the insulation jacket 5 is fixedly supported by a servo motor 8. The cooperation of the rotating shaft 6 and the spiral blade 7 can guide the flow of alcohol, and then achieve temperature conduction through the flow, ensuring the stability of heating.

[0022] A reflux pipe 12 is supported above the reflux evaporator 4. A condensate collection tank 11 is provided on the outside of the heating tank 1. A cooling tank 10 is supported above the condensate collection tank 11. The reflux pipe 12 can complete the discharge of steam, and the cooling tank 10 realizes the condensation of steam. The steam is then re-condensed and collected using the condensate collection tank 11.

[0023] A feed pipe 13 is fixedly connected to the top of the reflux evaporator 4. The feed pipe 13 is designed to deliver alcohol. The vertical cross-section of the heat-conducting flow pipe 3 is circular. The diameter of the heat-conducting flow pipe 3 is smaller than the height of the reflux evaporator 4. The heat-conducting flow pipe 3 is designed to connect the two opposite pipes of the U-shaped reflux evaporator 4.

[0024] The rotating shaft 6 passes through the inner cavity of the heat-conducting flow tube 3, and the spiral blade 7 is located inside the heat-conducting flow tube 3. The output shaft of the servo motor 8 is fixedly connected to one end of the rotating shaft 6. The rotation of the rotating shaft 6 and the spiral blade 7 can guide the flow of alcohol, thereby stabilizing the temperature conduction, facilitating the use of the equipment, and improving the practicality of the equipment.

[0025] The cooling box 10 is fitted outside the return pipe 12. The cooling box 10 can cool the return pipe 12. The inner cavity of the return pipe 12 and the inner cavity of the condensate collection box 11 are connected to each other.

[0026] In summary, this alcohol production distillation apparatus, during operation, firstly, cold water is poured into the heating tank 1 and the inner cavity of the water bath 2 through the upper part of the water bath 2, so that the water level is higher than the top surface of the reflux evaporator 4. Then, the alcohol to be distilled is poured into the inner cavity of the reflux evaporator 4 and the heat transfer pipe 3 through the feed pipe 13. The heating pipe 9 is then activated to heat the cold water in the inner cavity of the heating tank 1, maintaining the water temperature at 77°-79°. Subsequently, the hot water in the inner cavity of the water bath 2 conducts heat to the inner cavity of the heat transfer pipe 3, heating the alcohol in the inner cavity of the heat transfer pipe 3. Simultaneously, the servo motor 8 is activated, utilizing the output of the servo motor 8... The output shaft drives the rotating shaft 6 to rotate, which in turn drives the spiral blade 7 to rotate. During the rotation of the spiral blade 7, the alcohol inside the heat-conducting flow tube 3 is continuously kept in a flowing state, so that the alcohol is transported from the rear side of the heat-conducting flow tube 3 to the front side of the heat-conducting flow tube 3. At the same time, the flowing alcohol enters the inner cavity of the reflux evaporator 4 and flows from front to back, flowing to the rear of the heat-conducting flow tube 3 to form a circulation, so that the temperature is evenly conducted inside the alcohol. The evaporated alcohol enters the inner cavity of the reflux tube 12, is cooled by the cooling box 10, and condenses in the inner cavity of the condensate collection box 11, thus completing the purification.
