Description

Technical Field

[0001] This utility model relates to the field of curcumin purification technology, and in particular to a dissolving and stirring device for curcumin purification. Background Technology

[0002] Curcumin is a natural active substance extracted from the rhizome of turmeric and has a wide range of medicinal value. Its main components are diterpenoid compounds, which have various pharmacological effects such as anti-inflammatory, antioxidant, and anti-tumor activity.

[0003] To purify curcumin, a suitable solvent is selected based on its solubility. Commonly used solvents include ethanol, acetone, and ethyl acetate. The pulverized turmeric rhizome powder is added to an extraction tank, along with an appropriate amount of solvent, and the mixture is stirred and extracted.

[0004] When implementing existing technical solutions, the violent oscillations during the dissolution and stirring process introduce air, forming bubbles and foam. These bubbles and foam occupy space in the solution, reducing the effective contact area between curcumin and the solvent, thereby reducing dissolution efficiency. This may result in a longer dissolution time to achieve the expected dissolution effect. Summary of the Invention

[0005] The purpose of this invention is to provide a dissolving and stirring device for curcumin purification. The rotation of the dispersing and crushing plate can beat and break up the bubbles and foam generated by the surrounding dissolving and stirring, thereby reducing the content of bubbles and foam. Combined with the defoaming effect of the rotating and impacting crushing rod, the effect of eliminating bubbles and foam can be further improved, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dissolving and stirring device for curcumin purification, comprising a dissolving and stirring tank, wherein a dissolving and stirring assembly is provided both inside and outside the dissolving and stirring tank, the dissolving and stirring assembly comprising a drive shaft rotatably installed inside the dissolving and stirring tank, and a dispersion and defoaming assembly is provided outside the drive shaft;

[0007] The dispersion and defoaming component includes an assembly shaft fixedly installed on the outer wall of the drive shaft, an assembly shaft sleeve rotatably installed on the shaft wall of the assembly shaft, and dispersion and crushing plates distributed at equal angles fixedly installed on the outer wall of the assembly shaft sleeve.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A dissolving and stirring device for curcumin purification includes a dissolving and stirring tank 1. A dissolving and stirring assembly 4 is provided both inside and outside the dissolving and stirring tank 1. The dissolving and stirring assembly 4 includes a drive shaft 402 rotatably installed inside the dissolving and stirring tank 1. A dispersion and defoaming assembly 5 is provided outside the drive shaft 402. A curcumin root powder injection pipe 2, which communicates with the inside of the dissolving and stirring tank 1, is fixedly installed on one side of the upper end face of the dissolving and stirring tank 1. A dissolving discharge valve pipe 3 is fixedly connected to the bottom end of the dissolving and stirring tank 1. The dissolving and stirring assembly 4 also includes a drive motor 401 fixedly installed at the top of the dissolving and stirring tank 1. The output end of the drive motor 401 is fixedly connected to the drive shaft 402. A stirring rod 403 is fixedly installed on the outer wall of the drive shaft 402.

[0028] The dispersion and defoaming assembly 5 also includes a connecting sleeve 502 rotatably mounted on the upper end of the drive shaft 402. A metering valve pipe 501 is fixedly connected to one side of the outer wall of the connecting sleeve 502. A connecting hole 503 corresponding to the connecting sleeve 502 is opened on the top outer wall of the drive shaft 402. A first connecting channel 510 is opened inside the drive shaft 402. A second connecting channel 504 is opened inside the stirring rod 403. The metering valve pipe 501 is interconnected through the connecting sleeve 502, the connecting hole 503, the first connecting channel 510 and the second connecting channel 504. A dispersion spray hole 505 communicating with the second connecting channel 504 is opened on the outer wall of the stirring rod 403.

[0029] By adopting the above technical solution, during use, the turmeric root powder filling pipe 2 is connected to a turmeric root powder conveying device, thus conveying the turmeric root powder into the dissolving and stirring tank 1 through the turmeric root powder filling pipe 2. Simultaneously, the metering valve pipe 501 is connected to a solvent conveying device, thus conveying the solvent into the metering valve pipe 501. The metering valve pipe 501 is interconnected with the first connecting channel 510 through the connecting sleeve 502 and the connecting hole 503, thus conveying the solvent into the first connecting channel 510. Through the connection between the second connecting channel 504 and the first connecting channel 510, the liquid can be conveyed into the second connecting channel 504, and then... The dispersion spray hole 505 on channel 504 disperses the solvent. At the same time, the drive motor 401 is started, which drives the drive shaft 402 to rotate. The rotation of the drive shaft 402 drives the stirring rod 403 to rotate. The rotation of the stirring rod 403 causes the dispersion spray hole 505 to rotate and spray. This allows the solvent to be fully mixed with the turmeric root powder during addition. The stirring rod 403 can spray the solvent at multiple points at different heights, which can ensure that the solvent is more evenly distributed in the turmeric root powder, thereby further improving the dissolution efficiency during curcumin purification. The material after stirring and dissolving can be discharged through the dissolution discharge valve pipe 3.

[0030] Specifically, such as Figure 2, Figure 3 and Figure 5 As shown, the dispersion and defoaming component 5 includes an assembly shaft 506 fixedly installed on the outer wall of the drive shaft 402. An assembly bushing 507 is rotatably installed on the shaft wall of the assembly shaft 506. Dispersion and crushing plates 508 with equal angles are fixedly installed on the outer wall of the assembly bushing 507. The dispersion injection holes 505 correspond to the dispersion and crushing plates 508. A crushing rod 509 fixedly installed on the assembly shaft 506 is provided on one side of the dispersion and crushing plate 508. The assembly shaft 506 has an L-shaped structure.

[0031] By adopting the above technical solution, when dissolving and stirring, the stirring rod 403 will cause bubbles and foam to be generated inside the dissolving and stirring tank 1. At this time, the drive shaft 402 can drive the crushing rod 509 through the assembly shaft 506 to crush the surrounding bubbles. At the same time, the dispersion injection hole 505 corresponds to the dispersion and crushing plate 508, so that the solvent sprayed from the dispersion injection hole 505 acts on the dispersion and crushing plate 508. This allows the dispersion and crushing plate 508 to rotate on the assembly shaft 506 through the assembly bushing 507, thus dispersing and crushing. The rotation of plate 508 firstly breaks up the bubbles and foam generated by the surrounding dissolution and stirring, thereby reducing the content of bubbles and foam. Combined with the action of the breaking rod 509, it can further improve the effect of eliminating bubbles and foam. Secondly, the rotating dispersing and breaking plate 508 can play a dispersing role. The rotation of the dispersing and breaking plate 508 can make the solvent impacted by it more fully dispersed. Combined with the rotating spray of stirring rod 403 and dispersing spray hole 505, it can further improve the stirring and dissolution efficiency of solvent and turmeric root powder.

[0032] Working principle: In use, the turmeric root powder filling pipe 2 is connected to the turmeric root powder conveying device, which conveys the turmeric root powder into the dissolving and stirring tank 1. Simultaneously, the metering valve pipe 501 is connected to the solvent conveying device, which conveys the solvent into the metering valve pipe 501. The metering valve pipe 501 is interconnected with the first connecting channel 510 through the connecting sleeve 502 and the connecting hole 503, thus conveying the solvent into the first connecting channel 510. The second connecting channel 504 connects to the first connecting channel 510, conveying the liquid into the second connecting channel 504. The solvent is dispersed through the dispersion spray hole 505 on the second connecting channel 504. Simultaneously, the drive motor 401 is started, which drives the drive shaft 402 to rotate, which in turn drives the stirring rod 403 to rotate. The rotation of the stirring rod 403 causes the dispersion spraying hole 505 to rotate and spray, which allows the solvent to be fully mixed with the turmeric root powder during addition. When dissolving and stirring, the stirring rod 403 will cause bubbles and foam to be generated inside the dissolving and stirring tank 1. At this time, the drive shaft 402 can drive the crushing rod 509 through the assembly shaft 506 to crush the surrounding bubbles. At the same time, the dispersion spraying hole 505 and the dispersion crushing plate 508 correspond to each other, so that the solvent sprayed from the dispersion spraying hole 505 will act on the dispersion crushing plate 508. This allows the dispersion crushing plate 508 to rotate on the assembly shaft 506 through the assembly bushing 507. The rotation of the dispersion crushing plate 508 can first crush the surrounding bubbles and foam generated by the dissolving and stirring. The material after stirring and dissolving can be discharged through the dissolving discharge valve pipe 3.
