Description

Technical Field

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

[0002] Vacuum distillation is a distillation process carried out under conditions below atmospheric pressure. It is generally used to separate substances that are easily decomposed when heated to their boiling point at atmospheric pressure, or combined with other distillation methods (such as steam distillation) to lower the distillation temperature and improve separation efficiency.

[0003] Existing vacuum distillation apparatuses work by loading raw materials into a vacuum chamber, creating a vacuum environment inside the chamber, and then heating and distilling the raw materials inside the chamber. Since the raw materials are liquid, the environment inside the vacuum chamber is relatively humid, which makes it difficult to maintain the vacuum inside the chamber, thus affecting the distillation and separation efficiency.

[0029] Example 1:

[0030] This embodiment provides a vacuum distillation apparatus for separation and purification, which has the following technical features.

[0031] Please see Figure 1-6A vacuum distillation apparatus for separation and purification includes a vacuum device comprising a vacuum chamber 1, a closure assembly 2, and a vacuum assembly 3. The opening of the vacuum chamber 1 is rotatably connected to the closure assembly 2 via a hinge. The rear of the vacuum chamber 1 is connected to the vacuum assembly 3 via a bellows. A working platform 4 is fixedly connected inside the vacuum chamber 1. A heating cage 41 is fixedly installed on the upper part of the working platform 4. A fixing mold 42 is also installed on the upper part of the working platform 4. A distillation flask 5 is placed inside the fixing mold 42. Both the fixing mold 42 and the distillation flask 5 are located inside the heating cage 41. The heating cage 41 heats the raw material in the distillation flask 5.

[0032] Furthermore, a temperature detector is installed inside the vacuum chamber 1 to facilitate monitoring of the internal temperature of the tank.

[0033] It should be noted that the vacuum assembly 3 consists of a multi-stage vacuum pump, which evacuates the vacuum chamber 1 to achieve the target vacuum level.

[0034] In an optional embodiment, a reserved opening 11 is provided at the upper part of the vacuum chamber 1, and the connecting pipe at the upper part of the distillation flask 5 passes through the reserved opening 11.

[0035] Furthermore, the distillation flask 5 and the reserved opening 11 are sealed with a sealing ring.

[0036] In an optional embodiment, a condenser 51 is connected downward to the outside of the nozzle of the distillation flask 5, and a collector 52 is connected to the end of the nozzle.

[0037] Furthermore, the coolant inside the condenser 51 enters from the bottom and exits from the top.

[0038] In an optional embodiment, the fixed mold 42 includes a guide rail 421, a slider 422 and a fixing clamp 423 fixed on the upper part of the working platform 4. The upper part of the guide rail 421 is slidably connected to the slider 422, and the upper part of the slider 422 is fixedly connected to the fixing clamp 423. The distillation bottle 5 is disposed inside the fixing clamp 423.

[0039] Furthermore, the shape of the distillation flask 5 is matched with the shape of the fixing clip 423.

[0040] It should be noted that the fixing clip 423 serves to secure the distillation flask 5 and also prevents expansion.

[0041] In an optional embodiment, a detection port 12 is provided at the rear of the vacuum chamber 1, and a vacuum detector 6 is fixedly installed at the detection port 12. The vacuum detector 6 is located on one side of the vacuum assembly 3.

[0042] In an optional embodiment, a connector 7 is provided on the side of the vacuum chamber 1, and the connector 7 is electrically connected to the heating cage 41.

[0043] In an optional embodiment, the closing component 2 consists of a closing part 21, an observation window 22, and a handle 23, both of which are fixed to the closing part 21.

[0044] It should be noted that the observation window 22 is located in the middle of the closing part 21, and the handle 23 is set on the closing part 21 away from the hinge direction of the closing part.

[0045] Working principle: By opening the closing part 21 through handle 23, the distillation flask 5 is placed into the vacuum chamber 1. By moving the slider 422 on the guide rail 421, the two sets of fixing clamps 423 fix the distillation flask 5 inside the fixing clamps 423. At the same time, the fixing clamps 423 also prevent the distillation flask 5 from expanding and rupturing due to the pressure difference between the inside and outside of the distillation flask 5. Closing the closing component 2 makes the vacuum equipment a sealed state. The vacuum pump group is started to evacuate the vacuum chamber 1. The vacuum inside the vacuum chamber 1 is detected by the vacuum detector 6. When the expected vacuum level is reached, the vacuum pump is stopped, and the heating cage 41 is started to heat the distillation flask 5 from all sides to improve the distillation efficiency. During the distillation process, the operator can observe the distillation situation inside the distillation flask 5 through the observation window 22. The condenser 51 is started to cool the vapor in the connecting pipe, and the cooled liquid is collected by the collector 52.

[0046] In summary, the raw material is loaded into the interior of the distillation flask 5, which is then placed inside the vacuum chamber 1. The vacuum chamber 1 is evacuated using the vacuum assembly 3 to prevent the raw material from directly contacting the vacuum chamber 1 and thus preventing the vacuum from being drawn down. The distillation flask 5 inside is then heated by the heating cage 41, thereby improving the distillation separation efficiency.
