[0002] With the continuous development of the pharmaceutical industry, the requirements for the purification of intermediates in drug synthesis and the refining of final drug products are becoming increasingly stringent. Drug distillation equipment, as an important separation and purification method, can effectively remove impurities, improve the purity and quality of drugs, and meet the stringent requirements of pharmaceutical production. Therefore, its application in the pharmaceutical field is becoming increasingly widespread, and its technology is constantly developing and improving. Currently, there are few production units considering vacuum distillation.

[0003] To address the aforementioned problems, the purpose of this invention is to provide a drug purification and distillation apparatus. This apparatus uses an air pump to create a low-pressure environment within the sealed unit, allowing distillation to proceed under this low pressure. The low pressure lowers the boiling point of the original liquid, reducing heat energy consumption. Furthermore, the recycling of the cooling liquid further reduces material consumption, achieving energy conservation and emission reduction. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a drug purification and distillation apparatus, including a heating and rotating assembly, an evaporating kettle, a cooling assembly, a liquid receiving tank, and an air pump. The evaporating kettle is movably fixed on the upper end of the heating and rotating assembly, and the evaporating kettle and the cooling assembly are fixedly connected by a connecting pipe. The liquid receiving tank is located below the evaporating assembly, and the air pump is fixed on one side of the liquid receiving tank.

[0005] The evaporator, connecting pipes, condenser in the cooling assembly, and liquid collection tank are all tightly connected and sealed with sealing material at the joints.

[0006] In one example, the heating and rotating assembly includes a heating plate fixed to the support leg, a temperature control button on the side of the heating plate, a rotating plate movably connected to the top of the heating plate, a motor fixedly installed on one side of the support leg, the motor output end passing through the heating plate, and the motor output end fixedly connected to the center position of the bottom end of the rotating plate.

[0007] In one example, the evaporator is provided with a raw liquid inlet on the upper side, and a feed pipe of equal diameter is movably installed on the raw liquid inlet. The evaporator is fixedly connected to the top of the rotating plate, and a slider is fixedly connected to the upper end of the evaporator body. The slider is located inside the slide rail embedded in the evaporator lid, and sealing strips are provided on both sides of the slide rail. The top of the evaporator is penetrated by a capillary tube.

[0008] In one example, the bottom end of the capillary is adjacent to the bottom end of the evaporator body.

[0028] like Figures 1-4 As shown in the figure, an embodiment of the present invention provides a drug purification and distillation apparatus, which includes a heating and rotating assembly, an evaporating kettle 8, a cooling assembly, a liquid receiving tank 16, and an air pump 5.

[0029] Place the feed pipe of the raw liquid to be purified and distilled into an open container containing the raw liquid. The feed pipe is placed below the surface of the raw liquid. The feed pipe and the raw liquid inlet 9 are of the same diameter and the connection is sealed with a sealing material. The evaporator 8, connecting pipe 10, condenser 15 and liquid collection tank 16 are all tightly connected and the connection is sealed with a sealing material to make them as airtight as possible. Turn on the air pump 5 that is movably installed on the liquid collection tank 16. The air pump 5 starts to draw out the gas in the device. The internal pressure of the device decreases. Due to the pressure difference between the device side and the open container side of the raw liquid, the raw liquid will enter the evaporator 8 along the feed pipe.

[0030] After the raw liquid enters the evaporator 8, the feed port is closed. The evaporator 8 is fixedly connected to the rotating plate 4. The rotating plate 4 is fixed to the heating plate 2 by the slider and the track. The heating plate 2 is fixed to the support leg 1. Due to the low pressure environment created by the air pump 5, the boiling point of the raw liquid is reduced, thus reducing heat energy consumption and achieving the purpose of energy saving and consumption reduction. The heating plate 2 is turned on to heat. The heating plate 2 is equipped with a control button 3 on the side. The temperature can be adjusted by the control button 3 to maintain the raw liquid in a state of slight boiling.

[0031] The upper end of the evaporator 8 has a slider, which is located inside the slide rail embedded in the lid of the evaporator 8. There are sealing strips on both sides of the slide rail. The evaporator 8 and the lid of the evaporator 8 are movably connected together through the embedded slider slide rail. The evaporator 8 can rotate with the rotating plate 4, while the lid position remains unchanged. Due to the effect of the sealing strip, the evaporator 8 is in a relatively sealed state. The top of the heating plate 2 is provided with a track, and multiple sliders at the bottom of the rotating plate 4 are engaged inside the track. The motor 6 is fixed on the support leg 1. The output end of the motor 6 passes through the heating plate 2 and is fixed at the bottom center of the rotating plate 4. The rotation of the output end of the motor 6 can drive the rotation of the rotating plate 4, thereby driving the rotation of the evaporator 8. Due to the rotation of the evaporator, the original liquid flows in the evaporator, which can make the original liquid evenly heated and achieve the purpose of efficient evaporation. The lid of the evaporator 8 is penetrated by a capillary tube 7. The capillary tube 7 can allow a very small amount of air to enter the liquid, which in turn produces continuous tiny bubbles, thus preventing boiling over.

[0032] Vapor enters condenser 15 through connecting pipe 10. Condenser 15 is in the shape of an inverted funnel. Condenser 15 passes through cooling tower 11 and is threadedly connected to liquid collection tank 16. Vapor is condensed into purified liquid through cooling tower 11 and enters liquid collection tank 16.

[0033] The cooling tower 11 has a hollow structure with a coolant inlet and conduit 13 at the bottom and a coolant outlet and conduit 13 at the top. The coolant releases heat and its temperature decreases in the low-temperature environment of the refrigerator 12. The coolant enters the cooling tower 11 through the coolant inlet. The circulation pump 14 is installed inside the refrigerator 12. Due to the propulsion of the circulation pump 14, the coolant passes through the hollow part of the cooling tower 11 and reaches the coolant outlet. The coolant provides a low-temperature environment in the cooling tower 11, which causes the vapor in the condenser tube 15 to release heat and condense to form a purified liquid. Under the action of gravity, the liquid enters the liquid collection tank 16. The coolant enters the refrigerator 12 from the outlet for cooling and temperature reduction again, completing the position and temperature cycle of the coolant. The cooling and reuse of the coolant can realize the material loss in the distillation and purification process.

[0034] When the original liquid that needs to be distilled and purified cannot be purified by depressurization, the air pump 5 can be turned off after the depressurization feeding is completed, and distillation can be carried out in the conventional distillation method. At this time, the temperature of the heating plate 2 needs to be increased, and the zeolite needs to be introduced through the feed inlet to prevent bumping.

[0035] After purification, rotate the receiving hopper to remove it from the condenser tube 15. The receiving hopper is installed on the condenser tube 15 without touching the ground.

[0036] This invention uses an air pump 5 to create a low-pressure environment by drawing air from the sealed interior of the device. Distillation is carried out in this low-pressure environment, which lowers the boiling point of the raw liquid and reduces heat energy consumption. By circulating the coolant, material consumption is reduced, achieving the purpose of energy saving and consumption reduction. The capillary tube 7 and zeolite prevent bumping and avoid the overflow of the raw liquid. The steam passage part of the device is sealed to prevent steam from overflowing and affecting the environment, thus reducing the pollution caused by the distillation of the raw liquid.

[0037] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
