Description

Technical Field

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

[0002] Distillation equipment is widely used in the separation and purification of liquid mixtures in industries such as chemical, pharmaceutical and food processing, including chemical raw material refining, pharmaceutical intermediate extraction and food additive purification. It is a key piece of equipment for achieving the separation and purity improvement of target components, and its operating performance directly affects product quality and production efficiency.

[0003] In existing distillation apparatuses, most stirring structures are simply designed, often employing unidirectional or single-layer stirring components, making it difficult to achieve thorough mixing of materials. This easily leads to uneven heating of materials in certain areas, resulting in low distillation efficiency and even decomposition of heat-sensitive components. Furthermore, the temperature monitoring and control systems of existing apparatuses are inadequate, lacking real-time and accurate temperature feedback and control mechanisms. Additionally, the condensation structure has low condensation efficiency, and the collection of condensate lacks effective management. This not only easily affects the purity of the distilled product due to temperature fluctuations but may also cause product loss due to insufficient steam condensation or disordered collection. Some apparatuses also rely on manual operation, which is cumbersome and lacks precision. Therefore, a new distillation apparatus is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a distillation apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distillation apparatus, comprising:

[0006] Distillation kettle, heat transfer oil heating device, distillation column, condenser, receiving tank and CNC device;

[0007] The distillation vessel is made of stainless steel. The top of the distillation vessel has a feed inlet and the bottom of the distillation vessel has a discharge outlet. A temperature sleeve is provided on one side of the inside of the distillation vessel, and a thermometer is installed inside the temperature sleeve. A stirring motor is installed at the upper end of the inside of the distillation vessel, and a stirring shaft is installed at the output end of the stirring motor. A propeller with an upper inclined layer and a lower horizontal layer is provided outside the stirring shaft.

[0008] The distillation vessel and the distillation column are connected by a steam pipeline;

[0009] The heat transfer oil heating device includes an electric heating element, a circulation system and a controller, wherein the circulation system consists of a circulation pump and pipelines.

[0010] The condenser is connected to the distillation column. The upper part of the condenser is provided with a condenser outlet and the lower part of the condenser is provided with a condenser inlet. The middle of the condenser is a spiral condenser tube connected to an external condensate circulation pump.

[0011] The receiving tanks include two receiving tanks and a vacuum buffer tank connected by pipelines directly below the distillation column. Valves are installed at the input ends of both the receiving tanks and the vacuum buffer tank.

[0012] The numerical control device is connected to the outside of the device;

[0013] The distillation column is connected above the distillation vessel via a pipeline and is perpendicular to the receiving tank;

[0014] The stirring motor-driven upper inclined and lower horizontal propellers ensure thorough mixing of the materials, guaranteeing uniform heating and preventing uneven heating that could negatively impact distillation. A built-in thermometer in the temperature tube provides real-time temperature feedback within the distillation vessel. Combined with the controller and circulation system of the heat transfer oil heating device, the heating temperature can be precisely controlled, preventing temperature fluctuations from reducing the purity of the distilled product. A bottom-in, top-out spiral condenser, combined with an external condensate circulation pump, efficiently condenses vapor. Valves in the receiving tank and vacuum buffer tank allow for flexible adjustment of the condensate collection volume and distillation rate, minimizing product loss. A numerical control system provides intelligent management of the entire distillation process, reducing human error and improving the stability of the distillation process and the reliability of product quality.

[0016] Preferably, a viewing window feeding port is provided on the upper side of the other side of the outer wall of the distillation vessel, and the viewing window feeding port is connected to the distillation vessel. The viewing window feeding port is used for feeding and observation.

[0018] Preferably, the lower end of the distillation vessel is provided with a distillation vessel rack, and the distillation vessel rack is connected to the bottom of the distillation vessel, the distillation vessel rack being used to support the distillation vessel.

[0019] Compared with the prior art, the present invention provides a distillation apparatus with the following advantages:

[0020] This invention utilizes a stirring motor within the distillation vessel to drive an upper inclined and a lower horizontal propeller, achieving thorough stirring of the material and ensuring uniform heating. This solves the problem of uneven heating in certain areas leading to low distillation efficiency or component decomposition in traditional distillation. A built-in thermometer in the temperature tube sleeve monitors the temperature inside the distillation vessel in real time. Combined with the controller and circulation system of the heat transfer oil heating device, precise temperature control is achieved, preventing temperature fluctuations from affecting the purity of the distilled product and solving the problem of unstable product quality due to uncontrollable heating temperature. A bottom-in, top-out spiral condenser in the distillation column, along with an external condensate circulation pump, enables efficient steam condensation. Valves in the receiving tank and vacuum buffer tank control the condensate collection and distillation rate, improving distillation efficiency and product collection controllability, and solving the problem of product loss due to insufficient steam condensation or disordered collection. A numerical control device manages the entire apparatus, achieving intelligent distillation and reducing human error, solving the problems of cumbersome and inaccurate manual operation.
