[0026] Example

[0027] Reference Figure 1-Figure 4 The utility model provides a technical solution: a distillation device for producing pinacolone, comprising a processing tank 1 and a feeding mechanism 3, the bottom plate of the processing tank 1 is fixedly installed with an electric heating plate 2, the feeding mechanism 3 comprises a receiving plate 31, a linkage shaft 311 is installed inside the processing tank 1, a universal ball 312 is fixedly installed on the top of the linkage shaft 311, the universal ball 312 is movably connected to the receiving plate 31, a discharge hole 313 is opened on the upper surface of the receiving plate 31, a feed pipe 32 is fixedly installed inside the processing tank 1, one end of the feed pipe 32 is arranged outside the processing tank 1, a conical bin 331 is fixedly installed inside the processing tank 1, a grinding roller 33 is arranged inside the conical bin 331, and the grinding roller 33 is fixedly connected to the linkage shaft 311.

[0028] In a preferred embodiment, a through hole 4 is provided on the outer surface of the conical bin 331, and the grinding roller 33 is installed inside the conical bin 331 and rotated. The grinding roller 33 is set to a conical shape. The conical bin 331 is used in conjunction with the grinding roller 33. The device removes impurities in the mixed solution by adding reactants and mixing them with the mixed solution, thereby improving the purification effect of pinacolone. During the addition of reactants, there will be larger particles of reactants. In order to facilitate the addition of reactants to the bottom end of the processing tank 1, the grinding roller 33 is controlled to rotate inside the conical bin 331, and larger particles are moved to the inside of the conical bin 331. The larger particles can be ground by the grinding roller 33, and the powdered reactants are moved to the mixed solution, which is convenient for removing impurities in the mixed solution.

[0029] In a preferred embodiment, the interior of the processing tank 1 is fixedly connected to a liquid inlet pipe 5, on which a first control valve 6 is installed. The device realizes distillation and purification of pinacolone by processing the mixed liquid. To facilitate adding the mixed liquid into the interior of the processing tank 1, a liquid inlet pipe 5 is installed inside the processing tank 1, and a first control valve 6 is installed on the liquid inlet pipe 5 to facilitate adding the mixed liquid.

[0030] In a preferred embodiment, a condenser 7 is provided on one side of the processing tank 1, and the air inlet end of the condenser 7 is connected to the interior of the processing tank 1 through a pipe 8, and the liquid outlet end of the condenser 7 is connected to the interior of a collecting box 15 through a circular tube 9. The outer surface of the collecting box 15 is fixedly connected to a drain pipe 10, and a second control valve 11 is installed on the drain pipe 10. To facilitate the collection of pinacolone, a condenser 7 is installed on one side of the processing tank 1. The condenser 7 will convert steam into liquid, and the liquid will be transported to the interior of the collecting box 15, so as to collect the pinacolone inside the collecting box 15, which is convenient for operation.

[0031] The device adds reactants into the interior of the processing tank 1 to mix with the mixed liquid. In order to improve the mixing effect of the mixed liquid and the reactants, a stirring mechanism 12 is installed inside the processing tank 1. The stirring mechanism 12 includes a stirring disk 121, a rotating disk 122 and a connecting rod 123. One end of the connecting shaft 311 is fixedly connected to the connecting rod 123, the bottom end of the connecting rod 123 is fixedly connected to the stirring disk 121, and the outside of the connecting rod 123 is fixedly connected to the rotating disk 122. The position of the rotating disk 122 corresponds to the position of the liquid inlet pipe 5. A slag discharge hole 13 is opened at the bottom of the processing tank 1, and the inner plug of the slag discharge hole 13 is connected to the sealing plug 14.

[0032] During operation, the reactants are added into the interior of the processing tank 1 and dropped from the receiving plate 31 into the mixed liquid. At this time, the mixed liquid is continuously transported into the interior of the processing tank 1 through the liquid inlet pipe 5, and the rotating disk 122 is driven to rotate, which drives the stirring disk 121 to rotate continuously in the mixed liquid, thereby accelerating the rapid reaction of the reactants with impurities in the mixed liquid, and removing the impurities in the mixed liquid, thereby improving the purification effect of pinacolone and meeting the use requirements.

[0033] Specifically, the working process or working principle of a distillation device for producing pinacolone is as follows: the current common distillation method is to heat the mixture, utilize the different boiling points of various substances to heat the pinacolone into steam, and then transport the steam to a condensing device, liquefy the steam into liquid through the condensing device, and collect the liquid to obtain a relatively pure pinacolone.

[0034] Although the above distillation method can obtain relatively pure pinacolone, in actual operation, there will be some impurities in the mixture whose boiling point is lower than that of pinacolone. During the distillation process, these impurities will turn into steam early and easily mix with the pinacolone steam, resulting in some impurities being mixed in the subsequently collected pinacolone, affecting the use of pinacolone. Therefore, the present device is designed to solve this problem.

[0035] When using the device to distill and purify pinacolone, first connect the external power supply, add the mixed liquid into the interior of the processing tank 1 through the liquid inlet pipe 5, and turn on the electric heating plate 2. Since the mixed liquid continuously enters the interior of the processing tank 1, the liquid cannot be heated. Therefore, during this process, reactants such as ether, acetone and methanol can be added to the interior of the processing tank 1. One or more of the above reactants are added into the interior of the processing tank 1 through the feed pipe 32 and fall onto the receiving plate 31.

[0036] The device drives the rotating disk 122 to rotate while passing the liquid into the processing tank 1. When the rotating disk 122 rotates, it will drive the linkage shaft 311 to rotate, thereby driving the material receiving plate 31 to rotate. Since the material receiving plate 31 and the linkage shaft 311 are movably connected through the universal ball 312, the material receiving plate 31 will be tilted. At this time, the reactants on the material receiving plate 31 will slide from the upper surface of the material receiving plate 31, and the reactants will slide from the material receiving plate 31 to the inside of the conical bin 331. The powdered reactants will fall from the through hole 4 on the conical bin 331 into the mixed liquid. When the rotating disk 122 rotates, it will also drive the stirring disk 121 to rotate, thereby uniformly stirring the reactants in the mixed liquid, reacting the reactants with impurities in the mixed liquid to produce solids, and as the material receiving plate 31 continues to rotate, the reactants on the material receiving plate 31 will continue to fall into the mixed liquid to remove impurities in the mixed liquid.

[0037] The reactants may be mixed with larger particles of reactants. To facilitate their processing, the particle reactants fall from the receiving plate 31 to the inside of the conical bin 331. With the continuous rotation of the linkage shaft 311 and the connecting rod 123, the grinding roller 33 is driven to rotate continuously inside the conical bin 331, and the reactants inside the conical bin 331 are continuously rotated to grind them into powder. The powder will automatically fall into the mixed liquid and react with impurities to form a solid.

[0038] After a certain amount of the mixed liquid is added to the processing tank 1, the addition is stopped, and then the mixed liquid is continuously heated by the electric heating plate 2. When the temperature is heated to the boiling point of pinacolone, the heating can be stopped. At this time, the steam inside the processing tank 1 will be transported to the inside of the condenser 7, and the steam will be converted into liquid by the condenser 7, and then flow into the inside of the collection box 15, and the pinacolone will be collected inside the collection box 15, and then it can be collected.

[0039] There will still be liquid inside the processing tank 1. After each processing is completed, the sealing plug 14 is removed, and water is transported to the inside of the processing tank 1 through the liquid inlet pipe 5 to clean up the solid particles generated at the bottom of the processing tank 1. According to the above method, the connecting rod 123 is driven to rotate, which will drive the stirring plate 121 to rotate, and the solid particles are discharged from the inside of the slag discharge hole 13 through the stirring plate 121, and can be discharged together with the liquid.

[0040] It should be noted that the electric heating plate 2 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
