Abstract
Description
Technical Field
[0001] This utility model relates to the field of distillation apparatus technology, and specifically to a distillation apparatus. Background Technology
[0002] Distillation units are powerful and widely used chemical separation equipment. Based on the property that the components in a mixture have different volatility (i.e., boiling point differences), they separate the components by controlling changes in temperature and pressure, causing them to vaporize and condense at different temperatures. They are widely used in chemical, petroleum, pharmaceutical, food, environmental protection and other fields.
[0003] Currently, small distillation apparatuses are essential research equipment in the laboratory research and development process in the pharmaceutical field. After each use, the distillation apparatus needs to be cleaned to avoid affecting the distillation and purification accuracy of other compounds. However, existing small laboratory distillation apparatuses lack self-cleaning structures, which means that the apparatus must be manually disassembled and cleaned, which is time-consuming and labor-intensive. Furthermore, residual compounds may be toxic, thus affecting the health of researchers.
[0004] Therefore, a distillation apparatus is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a distillation apparatus in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A distillation apparatus includes a distillation tank, which includes a heating tank. A condenser assembly is fixedly mounted on the surface of the heating tank and is connected to it. A spray pipe is rotatably mounted on the top surface of the inner wall of the heating tank. A nozzle is fixedly mounted on the side of the spray pipe. Arc-shaped rods are fixedly mounted on the upper and lower surfaces of the spray pipe. A cleaning brush is fixedly mounted on the surface of the arc-shaped rods and is disposed in contact with the inner wall surface of the heating tank. A rotation drive assembly for driving the spray pipe to rotate is provided at the top of the heating tank. A supply pipe is fixedly mounted on the top surface of the heating tank.

The end of the air inlet pipe away from the condensation tube is fixedly mounted on the top wall of the heating barrel and communicates with the interior of the heating barrel. The end of the air outlet pipe away from the condensation tube passes through the side wall of the condensation chamber.
[0011] Furthermore, the rotation drive assembly includes a gear cavity and a motor. The gear cavity is located inside the top wall of the heating barrel. The motor is fixedly installed on the top surface of the heating barrel. A rotating shaft is fixedly connected to the output end of the motor.

[0025] like Figures 1 to 4 As shown, a distillation apparatus includes a distillation tank 1, which includes a heating tank 101. A condenser assembly 2 is fixedly installed on the surface of the heating tank 101, and the heating tank 101 and the condenser assembly 2 are connected. A spray pipe 3 is rotatably installed on the top surface of the inner wall of the heating tank 101. A nozzle 11 is fixedly installed on the side of the spray pipe 3. Arc-shaped rods 4 are fixedly installed on the upper and lower surfaces of the spray pipe 3. A cleaning brush 5 is fixedly installed on the surface of the arc-shaped rods 4. The cleaning brush 5 is set against the inner wall surface of the heating tank 101. A rotation drive assembly 6 for driving the spray pipe 3 to rotate is provided on the top of the heating tank 101. A supply pipe 7 is fixedly installed on the top surface of the heating tank 101. A water pump 8 is provided on the surface of the supply pipe 7. The outer side of the lower end of the supply pipe 7 is rotatably set against the inner side of the spray pipe 3. A sealing connection assembly 9 for sealing the connection between the spray pipe 3 and the supply pipe 7 is provided on the surface of the supply pipe 7.
[0026] More specifically, the cleaning solution is pumped into the spray pipe 3 by the water pump 8 and the supply pipe 7 and sprayed out through the nozzle 11 on the side of the spray pipe 3. The spray pipe 3 and the arc rod 4 fixedly installed on the surface of the spray pipe 3 are rotated synchronously by the rotation drive component 6, so that the cleaning solution is evenly sprayed on the inner wall surface of the heating tank 101. The inner wall of the heating tank 101 is scrubbed by the arc rod 4 and the cleaning brush 5, so as to achieve efficient and comprehensive automated cleaning without the need for manual removal of the heating tank 101 for cleaning, avoiding the harm of residual compounds to the health of experimental researchers, and making the cleaning work safer and more reliable. It can quickly connect the distillation work of pharmaceutical intermediate solutions with different components, avoid component contamination, and improve the distillation effect. The sealing connection component 9 ensures that the cleaning solution enters the spray pipe 3 smoothly through the supply pipe 7 without overflowing, and the spray pipe 3 can rotate smoothly at the same time.
[0027] A support leg 102 is fixedly installed on the bottom surface of the heating tank 101, an inlet pipe 103 is fixedly installed on the side of the heating tank 101, and a drain pipe 104 is fixedly installed in the middle of the bottom surface of the heating tank 101. Solenoid valves 105 are provided on the surface of both the inlet pipe 103 and the drain pipe 104.
[0028] Specifically, the liquid to be distilled enters the heating tank 101 through the inlet pipe 103. After the heating tank 101 starts heating, the gaseous fraction rises and enters the condenser 2 for condensation. After the distillation is completed, the remaining liquid is discharged through the drain pipe 104. After the inside of the heating tank 101 is cleaned, the waste liquid generated by the cleaning is also discharged through the drain pipe 104. The opening and closing of the inlet pipe 103 and the drain pipe 104 are controlled by the solenoid valve 105.
[0029] A cross block 10 is fixedly installed on the inner surface of the upper end of the drain pipe 104, and the lower end of the spray pipe 3 is rotatably installed on the top surface of the cross block 10.
[0030] Specifically, the lower end of the spray pipe 3 is limited by the cross block 10, so that the rotation of the spray pipe 3 remains stable and reliable.
[0031] The condenser assembly 2 includes a mounting ring 201, which is fixedly mounted on the surface of the heating tank 101. A condenser box 202 is fixedly mounted on the surface of the mounting ring 201. A condenser tube 204 is fixedly mounted inside the condenser box 202. An air inlet pipe 203 is fixedly connected to the upper end of the condenser tube 204, and an exhaust pipe 205 is fixedly connected to the lower end of the condenser tube 204. The end of the air inlet pipe 203 away from the condenser tube 204 is fixedly mounted on the top wall of the heating tank 101 and communicates with the interior of the heating tank 101. The end of the exhaust pipe 205 away from the condenser tube 204 passes through the side wall of the condenser box 202.
[0032] Specifically, the gaseous fraction enters the condenser 204 through the inlet pipe 203. By injecting condensate into the condenser 202, the temperature of the gaseous fraction in the condenser 204 can be quickly reduced, causing the fraction to liquefy rapidly. Finally, it is discharged through the outlet pipe 205, achieving rapid and efficient condensation and improving condensation efficiency. After the distillation is completed, cleaning liquid is injected into the condenser 204 through the end of the outlet pipe 205. The cleaning liquid washes the inner wall surfaces of the outlet pipe 205, the condenser 204 and the inlet pipe 203 and is finally discharged into the heating tank 101, which can achieve simultaneous cleaning of the condenser assembly 2 and the heating tank 101.
[0033] The rotation drive assembly 6 includes a gear cavity 601 and a motor 602. The gear cavity 601 is located inside the top wall of the heating tank 101. The motor 602 is fixedly installed on the top surface of the heating tank 101. The output end of the motor 602 is fixedly connected to a rotating shaft 603. The rotating shaft 603 is rotatably installed on the top and bottom surfaces of the inner wall of the gear cavity 601. A drive gear 604 is fixedly installed on the surface of the rotating shaft 603. A driven gear 605 is meshed on the surface of the drive gear 604. The spray pipe 3 is rotatably installed through the gear cavity 601. The driven gear 605 is fixedly fitted onto the surface of the spray pipe 3.
[0034] Specifically, the output end of the motor 602 drives the rotating shaft 603 and the driving gear 604 to rotate, which in turn drives the driven gear 605 meshing with the surface of the driving gear 604 to rotate, and finally drives the spray pipe 3 fixedly connected to the driven gear 605 to rotate, so as to achieve uniform water spraying and washing.
[0035] The sealing connection assembly 9 includes an overflow cover 901 and a rotating ring 903. The overflow cover 901 is fixedly installed on the side of the liquid supply pipe 7, and the rotating ring 903 is fixedly installed on the side of the liquid spray pipe 3. The bottom surface of the overflow cover 901 is set to fit against the top surface of the liquid spray pipe 3 and the top surface of the rotating ring 903. A T-shaped ring 902 is fixedly installed on the bottom surface of the overflow cover 901 and is rotatably installed inside the rotating ring 903. A sealing ring 904 is fixedly installed on the side of the overflow cover 901 and the bottom surface of the sealing ring 904 is set to fit against the top surface of the rotating ring 903.
[0036] Specifically, through the cooperation of the T-shaped ring 902 and the rotating ring 903, the bottom surface of the overflow cover 901 and the top surface of the rotating ring 903 are reliably attached, while the rotating ring 903 can rotate relative to the overflow cover 901. The overflow cover 901 and the T-shaped ring 902 cooperate to form the first layer of water barrier. At the same time, the sealing ring 904 fixedly installed on the outer side of the overflow cover 901 forms the second layer of sealing barrier, effectively preventing water entering the spray pipe 3 through the liquid supply pipe 7 from overflowing from the upper end of the spray pipe 3.
[0037] In summary: By using the water pump 8 and the liquid supply pipe 7, the cleaning solution is poured into the spray pipe 3 and sprayed out through the nozzle 11 on the side of the spray pipe 3. The rotating drive assembly 6 drives the spray pipe 3 and the arc-shaped rod 4 fixedly installed on the surface of the spray pipe 3 to rotate synchronously, so that the cleaning solution is evenly sprayed on the inner wall surface of the heating tank 101. The arc-shaped rod 4 and the cleaning brush 5 are used to scrub the inner wall of the heating tank 101, so as to achieve efficient and comprehensive automated cleaning. There is no need to manually remove the heating tank 101 for cleaning, which avoids the health hazards of residual compounds to experimental researchers. This makes the cleaning work safer and more reliable. It can quickly connect the distillation work of pharmaceutical intermediate solutions with different components, avoid component contamination, and improve the distillation effect.
