[0003] Although the traditional distillation method can effectively separate liquid components with different boiling points, in some cases, due to the presence of components that are difficult to volatilize, components with similar boiling points, or high liquid viscosity in the liquid mixture, the distillation process is inefficient and the separation effect is not ideal. During the heating process, the temperature distribution on the liquid surface is uneven, which is prone to local overheating, which may cause thermal decomposition or polymerization of certain components in the liquid. At the same time, due to the limited contact area between the liquid surface and the gas, the diffusion rate of molecules is slow, further reducing the distillation efficiency. Utility Model Content

DETAILED DESCRIPTION
[0021] The following is a more detailed description of the distillation apparatus for chemical product research and development experiments of the present invention in conjunction with the accompanying drawings and through specific implementation methods.
[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0023] The distillation apparatus for chemical product research and development experiments in this embodiment, the combined use of cooling tubes and condensing tubes, and the stable design of the clamping parts effectively improve the distillation efficiency and the accuracy and reliability of the experimental data, see Figure 1-Figure 2 , including a beaker 1, a distillation head 3, a cooling tube 4 and a condenser 404: the top of the beaker 1 is sealed and connected to the distillation head 3, the top of the beaker 1 is sealed and connected to a feed pipe 201 and a pressure relief pipe 2, the side wall of the beaker 1 is connected to a discharge pipe 202, and the outer surface of the distillation head 3 is wrapped with a mercury temperature wrapping ring 302. The temperature of the steam in the distillation head 3 can be observed through the mercury temperature wrapping ring 302, which is convenient for controlling the heating device at the bottom of the beaker 1.
[0024] The end of the distillation head 3 away from the beaker 1 is connected to one end of the condenser 404, the cooling tube 4 is wrapped around the outer surface of the condenser 404, the top and bottom of the side wall of the cooling tube 4 are respectively connected to the cold water inlet pipe 401 and the cold water outlet pipe 402, the other end of the condenser 404 is connected to the receiving pipe 403, and a clamping piece 301 is clamped between the distillation head 3 and the cooling tube 4. The clamping piece 301 is used to clamp the cooling tube 4 to improve the stability of the cooling tube 4, and valves are provided on the pressure relief pipe 2, the feed pipe 201 and the discharge pipe 202.
[0025] In this embodiment, the design of the fast-evaporating stirring element greatly improves the distillation efficiency. The meshing of the double arc gear and the helical gear realizes the efficient rotation of the stirring rod, increases the convection in the liquid, promotes the heat transfer, and thus improves the rapid heating and evaporation of the liquid. The combination of the handle and the limit ring rail, combined with the magnetic control, allows the user to easily control the operation of the stirring element without opening the beaker, simplifies the operation process, and maintains the overall sealing of the beaker, ensuring the safety of the experimental process and the accuracy of the data, see Figure 1 and Figure 3-4 The beaker 1 is provided with a fast-evaporating stirring member inside, and the fast-evaporating stirring member includes a double circular arc gear 6, a transmission rod 601, a second magnetic block 603, a stirring rod 605, a bevel gear 606 and a stirring blade 607. The second bearing 608 is fixed on both sides of the inside of the beaker 1. The two ends of the transmission rod 601 are fixed to the inner ring of the second bearing 608. The double circular arc gear 6 is wrapped around the outer surface of the transmission rod 601. The other end of the transmission rod 601 is fixed with a support plate 602. The second magnetic block 603 is fixed to a side wall of the support plate 602. Two first bearings 604 are fixed to the inner bottom wall of the beaker 1. The bottom of each stirring rod 605 is fixed to the inner ring of the first bearing 604. The first bearing 604 can be used to support the stirring rod 605, so that the stirring rod 605 can rotate more smoothly.
[0026] A plurality of stirring blades 607 are wrapped around the outer surface of the stirring rod 605, the top of the stirring rod 605 is fixed to the bevel gear 606, and the two sides of the double circular arc gear 6 are respectively meshed with the bevel gear 606. A limiting ring rail 5 is fixed to one side wall of the beaker 1, and a handle 501 is provided on the limiting ring rail 5. A groove for sliding on the limiting ring rail 5 is provided at one end of the handle 501, and a first magnetic block 502 adapted to the second magnetic block 603 is fixed at one end of the handle 501. Without opening the beaker, the stirring element can be driven to work by rotating the handle, which is easy to operate and realizes the overall sealing of the beaker.
[0027] The method of using the distillation device for chemical product research and development experiments of the utility model is as follows: first, the liquid chemical mixture to be separated is added into the interior of the beaker 1 through the feed pipe 201, and then the bottom of the beaker 1 is heated by an external burner to the boiling point of one or more components therein, so that some components in the liquid begin to vaporize. As the temperature rises, the components with lower boiling points in the liquid will first be converted into steam. Since different components have different boiling points, they will gradually separate during the evaporation process.
[0028] The steam generated during heating is discharged into the interior of the condenser 404 through the distillation head 3, and cold water is added into the interior of the cooling tube 4 through the cold water inlet pipe 401. When the cold water is overheated, it is discharged through the cold water outlet pipe 402. The steam in the condenser 404 is condensed back into liquid by the cooling of the cold water in the cooling tube 4. The condensed liquid drips into an external collector, thereby achieving separation of the mixture.
[0029] During the heating process, the handle 501 and the first magnetic block 502 can be rotated to make the handle 501 rotate in the limiting ring track 5, and the first magnetic block 502 attracts the second magnetic block 603 inside the beaker 1, thereby driving the second magnetic block 603 to rotate with the first magnetic block 502, and the second magnetic block 603 drives the support plate 602 to rotate, the support plate 602 drives the transmission rod 601 to rotate, the transmission rod 601 drives the double arc gear 6 to rotate, and the double arc gear 6 drives the two bevel gears 606 to rotate. The bevel gear 606 drives the stirring rod 605 and the stirring blade 607 to rotate to stir the liquid in the beaker 1, increase the speed of heat transfer, and make the liquid heated and evaporated faster.
[0030] Under the action of stirring, the surface of the liquid will be continuously heated by the bottom of the beaker 1, and the temperature distribution will be more uniform, reducing the unevenness of the evaporation temperature. It can also increase the gas-liquid interface area and the instability of the gas-liquid interface, enhance the diffusion rate of molecules, and thus speed up the distillation rate. When the liquid surface is continuously swept by the gas, the inlet part will change due to the influence of temperature, with the volatilized liquid on one side and the liquid that has not yet evaporated on the other side. This instability makes the liquid more likely to evaporate during the distillation process.
