Description

Technical Field

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

[0002] A chemical distillation unit is a key piece of equipment widely used in the chemical industry to separate different components in a liquid mixture. Based on the differences in volatility of the components in the mixture, it achieves high-purity separation of the mixture through multiple partial vaporization and partial condensation processes. The unit typically consists of several parts, including a distillation column, reboiler, condenser, reflux tank, and transfer pump. The distillation column is the core component, equipped with trays or packing to provide sufficient contact between the gas and liquid phases. The reboiler partially vaporizes the liquid at the bottom of the column, generating rising vapor; the condenser condenses the vapor at the top of the column into liquid, with a portion returning to the column as reflux to maintain stable distillation operations. Thanks to this sophisticated design and operating principle, chemical distillation units can efficiently extract products such as gasoline and diesel from crude oil, playing an indispensable role in numerous industries, including petrochemicals, fine chemicals, and pharmaceuticals.

[0003] Patent publication number CN218248566U discloses a chemical distillation apparatus, including a bottom plate, a distillation mechanism disposed on the top surface of the bottom plate, a reflux mechanism disposed on the bottom surface of the distillation mechanism, a heater disposed on the top surface of the bottom plate, the bottom surface of the heater being fixedly connected to the top surface of the bottom plate, a flame concentrator disposed on the top surface of the heater, the bottom surface of the flame concentrator being fixedly connected to the top surface of the heater, and a distillation tank disposed on the top surface of the flame concentrator.

[0004] To address the issues of monotonous evaporation effects, lack of reflux control, and unsatisfactory evaporation results, existing technologies employ distillation mechanisms to achieve rectification. While reflux mechanisms can further refine the sample through distillation, other problems arise, such as the inability to adjust the distillation tank height, difficulty in replacing the heater, lack of filtration devices, inability to remove impurities from the filter, and difficulty in cleaning the filter, leading to inconvenience in use.

After repeated heating, the liquid is distilled. Finally, the distilled liquid is placed in the collection tank 42. By adjusting the extension end of the electric telescopic rod 39, the scraper 37, sealing plate 1 33 and sealing plate 2 38 are moved to discharge the solid particles and impurities inside the feed pipe 31.
