Description

Technical Field

[0001] The utility model relates to the technical field of purification, in particular to a sodium trifluoroacetate purification device. Background Art

[0002] Purification is a very comprehensive concept, including all processes that can separate and purify all mixtures, such as distillation, extraction, crystallization, etc. Solid organic compounds obtained by organic reactions or extraction from natural products are often impure. The most commonly used purification methods are recrystallization or distillation cooling. After the compound is purified, some solid compounds need to be dried.

[0003] However, the existing sodium trifluoroacetate purification device still has some shortcomings in actual use: in use, the existing purification device only uses a single stirring method to achieve more complete and uniform drying of the compound, and the stirring blades are driven by the stirring shaft to mix the compound. However, during the stirring process, due to the limitation of the rotation radius, some compounds will accumulate in the corners and not participate in the mixing. This results in the inability to effectively improve the drying efficiency of the purification device during production, thereby reducing the use effect of the drying purification device.

[0004] Therefore, we designed a sodium trifluoroacetate purification device to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Uniform stirring and vibration drying: The drying chamber is equipped with a stirring device, which drives the stirring rod and connecting plate to rotate through the output motor, achieving rapid and uniform mixing and stirring of the internal compounds. At the same time, the driving motor drives the rocker to rotate, and then the drying chamber vibrates through the transmission mechanism.

[0014] High-efficiency filtration and low-temperature crystallization: The impurity solution is first filtered through the filter in the feed port, effectively removing large particles of impurities in the solution and providing purer raw materials for subsequent processing. Subsequently, the circulating water system of the water-cooling component is used to dissipate heat from the water in the water pipe through the cooling chamber, creating a low-temperature environment for the crystallization chamber, which is conducive to the rapid precipitation of solutes in the solution and the formation of a large number of crystals, thereby improving the crystallization efficiency and purity.

[0015] Automated separation and collection: When a large amount of crystals are precipitated from the solution in the crystallization chamber, the opening of the flow port is controlled by the electromagnetic valve, so that the solution containing crystals automatically flows into the drying chamber for static stratification. This design not only simplifies the operation process, but also avoids the pollution and efficiency loss that may be caused by manual operation. After stratification, the waste liquid of the impurity solution flows out through the liquid outlet pipe, while the deposited crystals remain in the drying chamber, realizing the effective separation and collection of solution and crystals.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5The utility model provides a technical solution: a sodium trifluoroacetate purification device, comprising a workbench 1, a crystallization chamber 2, a drying chamber 4, a stirring assembly and a water-cooling assembly. The interval between the legs fixedly installed at the bottom of the workbench 1 is greater than the frame width of the drying chamber 4. The crystallization chamber 2 is installed on the top surface of the workbench 1. A pair of first mounting blocks 5 are fixedly connected to both sides of the workbench 1. The bottom surface of the first mounting block 5 is fixedly connected to an elastic component 6. The end of the elastic component 6 away from the first mounting block 5 is fixedly connected to a second mounting block 7. The second mounting block 7 is fixedly installed on the outer wall of the drying chamber 4. The top surface of the drying chamber 4 is fixedly connected to a first connecting block 8, and the first connecting block 8 is rotatably connected to the first rotating shaft 9. The bottom surface of the workbench 1 is fixedly connected to a pair of second connecting blocks 11, and a driving motor is arranged between the pair of second connecting blocks 11. The second connecting block 11 is rotatably connected to the second rotating shaft 12 on the side away from the drying chamber 4, and the second rotating shaft 12 is fixedly connected to the rocker 13 on the end away from the second connecting block 11. A driving rod 10 is provided on the side of the rocker 13 away from the crystallization chamber 2, and one end of the driving rod 10 is fixedly mounted on the first rotating shaft 9, and the other end is rotatably connected to the rocker 13.

[0024] During specific implementation, the driving motor located between the second connecting blocks 11 is started, and the second rotating shaft 12 provides power to make the rocker 13 rotate around the second rotating shaft 12, thereby driving the driving rod 10. The driving rod 10 drives the drying chamber 4 to vibrate through the first rotating shaft 9. The drying chamber 4 is suspended by four elastic components 6. The vibration of the drying chamber 4 can drive the compounds being stirred and mixed inside to vibrate stably. The vibration of the compounds can create gaps between the compounds, and can enable the drying chamber 4 to dry and purify the compounds stably and evenly, thereby achieving the effect of vibration stirring.

[0025] See Figure 1-5 As shown, the stirring assembly includes an output motor 14, and the outer wall of the drying chamber 4 is fixedly connected to a protective shell 22. The output motor 14 is installed inside the protective shell 22. A fixed rod 15 is fixedly sleeved on the drive shaft of the output motor 14. A stirring rod 16 is fixedly connected to the surface of the fixed rod 15. There are several stirring rods 16, and the several stirring rods 16 are arranged at equal distances. The end of the stirring rod 16 away from the fixed rod 15 is fixedly connected to a connecting plate 17, and one side of the fixed rod 15 is fixedly connected to a fixed block 18. The side of the fixed block 18 away from the fixed rod 15 is fixedly connected to a limiting ring 19. A limiting block 20 is provided on one side of the limiting ring 19, and a limiting groove 21 is provided on the limiting block 20. The limiting groove 21 is adapted to the limiting ring 19 and the fixed block 18, and the limiting ring 19 is movably connected to the inside of the limiting groove 21.

[0026] The output motor 14 is started, and the output end of the output motor 14 rotates to drive the fixed rod 15 to rotate, thereby driving the stirring rod 16 and the connecting plate 17 to rotate. The rotation of the connecting plate 17 can quickly and evenly mix and stir the compounds inside the drying chamber 4. This combination of vibration and stirring not only promotes uniform mixing between the compounds, but also accelerates the evaporation of water during the drying process through the gaps generated by the vibration, thereby improving the drying efficiency and purification effect.

[0027] See Figure 1-5 The water cooling assembly includes a water pipe 25. A pipe groove is provided at the bottom and side wall of the crystallization chamber 2. The middle section of the water pipe 25 is fixedly mounted on the pipe groove. The top surface of the workbench 1 is fixedly connected to the cooling chamber 3 and the water pump 26. One end of the water pipe 25 passes through the pipe groove and is fixedly connected to one end of the water pump 26, and the other end passes through the pipe groove and is fixedly connected to one end of the cooling chamber 3. The water pump 26 of the water cooling assembly circulates the water in the water pipe 25. The water in the water pipe 25 is cooled and dissipated through the cooling chamber 3. The water cooling assembly is used to provide a low-temperature environment for recrystallization, which is conducive to the rapid precipitation of solutes in the solution and the formation of a large number of crystals, thereby improving the crystallization efficiency and purity.

[0028] See Figure 1-5 A feed port 23 is provided on the top surface of the workbench 1, and a filter screen 24 is fixedly connected to the inner wall of the feed port 23. The impurity solution is first filtered through the filter screen 24 in the feed port 23, which effectively removes large particles of impurities in the solution and provides purer raw materials for subsequent processing.

[0029] See Figure 1-5 A flow port 27 is provided on the bottom surface of the workbench 1, and a solenoid valve is provided in the flow port 27. A hose 28 is fixedly connected to one end of the flow port 27 close to the drying chamber 4. This design not only simplifies the operation process, but also avoids the pollution and efficiency loss that may be caused by manual operation.

[0030] Working principle: The impurity solution is filtered through the filter screen 24 in the feed port 23 and then enters the crystallization chamber 2. The water pump 26 of the water cooling assembly circulates the water in the water pipe 25. The water in the water pipe 25 is cooled and dissipated through the cooling chamber 3. The water cooling assembly is used to provide a low-temperature environment for recrystallization.

[0031] When a large amount of crystals are precipitated from the solution in the crystallization chamber 2, the electromagnetic valve of the flow port 27 is opened, allowing the solution with a large amount of crystals to enter the drying chamber 4 through the hose 28. The solution is allowed to stand in the drying chamber 4 and then separate into layers. The impurity solution at the top flows out through the waste liquid outlet pipe, and the deposited crystals at the bottom remain in the drying chamber 4.

[0032] When in use, the output motor 14 is started, and the output end of the output motor 14 rotates to drive the fixed rod 15 to rotate, thereby driving the stirring rod 16 and the connecting plate 17 to rotate. The rotation of the connecting plate 17 can quickly and evenly mix and stir the compounds inside the drying chamber 4.

[0033] The driving motor located between the second connecting blocks 11 is started, and the second rotating shaft 12 provides power, so that the rocker 13 rotates around the second rotating shaft 12, thereby driving the driving rod 10. The driving rod 10 drives the drying chamber 4 to vibrate through the first rotating shaft 9. The drying chamber 4 is suspended by four elastic components 6. The vibration of the drying chamber 4 can drive the compounds being stirred and mixed inside to vibrate stably. The vibration of the compounds can create gaps between the compounds, and can enable the drying chamber 4 to dry and purify the compounds stably and evenly, thereby achieving the effect of vibration stirring.
