Description

Technical Field

[0001] The invention relates to the technical field of silibinin preparation, and in particular to a silibinin rapid extraction and purification device and process. Background Art

[0002] Silybin is a flavonoid compound extracted and separated from the fruit of the Asteraceae plant Silybum marianum. The extraction and purification process of silybin includes several key steps: first, the fruit of Silybum marianum needs to be collected and processed into raw materials suitable for extraction; the processed raw materials are extracted, usually using a suitable solvent (such as ethanol, methanol, etc.) through soaking, stirring, etc., so that silybin is dissolved from the raw materials into the solvent; the extracted solution needs to be filtered to remove solid impurities, and then the solvent is removed by evaporation or concentration to obtain a concentrate containing silybin; the concentrate is further purified by column chromatography, crystallization, countercurrent distribution and other methods to obtain silybin of higher purity; the purified silybin is dried and packaged as needed for further use or sale.

[0003] At present, there are some existing technologies that can extract and purify silybin, for example, the patent publication number is CN220968751U, and its main technical means is to use a motor to drive a driving shaft to drive a stirring rod to rotate, and at the same time, the driving shaft will drive a connecting rod to rotate, and the connecting rod will drive a scraper to rotate. Under the action of the scraper, the stirring blind spot is eliminated and the stirring dead angle is avoided. After analysis, the disadvantage of this technical solution is that part of the solution is infiltrated in the raw material after stirring, and direct removal after filtration will cause this part of the solution that is most fully integrated with the silybin raw material to be wasted, resulting in the inability to fully extract silybin, resulting in a decrease in the amount of silybin extracted. Based on this, the present invention provides a silybin rapid extraction and purification device and process with a simple and ingenious structure, which can fully utilize the solution infiltrated in the silybin raw material for purification.

When it reaches the highest point of its moving path, the assembly rod 10 is docked with the stirring shaft 5 through the locking assembly 9.

[0049] like Figure 2-Figure 3 As shown, as a preferred embodiment of the present invention, when the filter disc 6 is at the lowest point of its moving path, it blocks the feed pipe 4; in actual application of this embodiment, after the filter disc 6 rises, the feed pipe 4 can be connected with the lower tank body 1, and then when the on-off valve on the feed pipe 4 is opened, the feed pipe 4 can transport the material under the filter screen 7 in the lower tank body 1 to the purification tank, and the feed pipe 4 is completely free of silybin raw materials.

[0051] In actual application of this embodiment, for the raw materials on the filter screen 7, the partition block 13 first rotates here to partition the raw materials, which can ensure that each scattering wheel 12 contacts the raw materials. Then the scattering wheel 12 rotates here and rotates by itself to scatter the raw materials in each area. Finally, the squeezing roller 11 rotates here to crush the scattered raw materials and fully squeeze out the solution infiltrated in the raw materials.

[0052] like Figure 2-Figure 7 As shown, as a preferred embodiment of the present invention, the transmission assembly 8 includes:

[0053] The fixed shaft 801 is sleeved on the outside of the shaft body 14, and the two are rotatably connected. The shaft body 14 is fixed to the top of the assembly rod 10 at a position corresponding to the bottom of the stirring shaft 5. The clamping assembly 9 is installed in the shaft body 14 to connect the shaft body 14 and the stirring shaft 5. The shaft body 14 passes through the filter screen 7, and the fixed shaft 801 is fixedly connected to the filter screen 7; and

[0054] The first gear 802 is coaxially fixedly mounted on the fixed shaft 801 and meshes with a second gear 803 rotatably mounted in the assembly rod 10 . The second gear 803 is connected to a plurality of breaking wheels 12 via a belt.

During this process, the fixed shaft 801 and the first gear 802 remain stationary with the filter screen 7, and the assembling rod 10 drives the second gear 803 to rotate with the axis of the shaft body 14 as the rotation axis. At the same time, under the action of the meshing transmission, the second gear 803 rotates on its own, and the belt can be used to drive a plurality of breaking wheels 12 to rotate on their own. At the same time, the plurality of breaking wheels 12 rotate with the assembling rod 10 with the axis of the shaft body 14 as the rotation axis, thereby achieving the breaking up of the raw materials on the filter screen 7.

If the slot 903 is misaligned with the top block 902, the block 902 is pushed down and the elastic member 905 is squeezed and contracted by the movable rod 901 and the bottom block 902 until the slot 903 is rotated to align with the top block 902. The elastic force causes the top block 902 to rise and engage with the slot 903, completing the engagement of the shaft body 14 with the stirring shaft 5, that is, the engagement of the assembly rod 10 with the stirring shaft 5. The rotation of the stirring shaft 5 can drive the assembly rod 10 to rotate with the axis of the stirring shaft 5 as the rotation axis.
