Description

Technical Field

[0001] The invention relates to the technical field of silymarin purification and separation, and more specifically, to a separation device and process for silymarin purification. Background Art

[0002] Silymarin is an important medicinal ingredient extracted from the milk thistle plant and is widely used in the treatment of liver diseases and in the field of anti-oxidation. The purification process requires separating the active ingredient from the broken plant tissue. Traditional processes usually use multi-stage filtration and centrifugal separation, but the leaf fragments, seed particles and fine burrs mixed in the milk thistle stock solution can easily cause clogging of the filter medium and reduce separation efficiency. Especially in continuous production processes, frequent filter cloth cleaning and shutdown maintenance seriously restrict production capacity. At the same time, residual impurities may affect the purity of the final product.

[0003] Existing filtration devices mostly use fixed filter screens or static centrifugal structures, which are difficult to adapt to the complex characteristics of solid particles in milk thistle concentrate, especially leaf fuzz, which is easy to embed into the gaps between filter cloth fibers, causing irreversible blockage and reducing the filtration and purification efficiency. At the same time, manual disassembly and cleaning are required, which increases time costs. In addition, traditional equipment lacks a dynamic cleaning mechanism and cannot simultaneously remove attached impurities during the filtration process, resulting in a significant decrease in filtration efficiency with running time. Some improvement plans attempt to introduce mechanical vibration to assist in slag removal, but it is difficult to balance the vibration intensity and the life of the filter cloth, and the problem of retention of fine fuzz cannot be solved.

[0054] The filtering mechanism 600 also includes a mounting ring 605 sleeved on the outside of the central axis 200, the outside of the mounting ring 605 is uniformly connected to a support frame 606 by a universal joint, and one end of the support frame 606 away from the mounting ring 605 is universally connected to a support block 604, and a synchronous connection section 603 is connected between two adjacent groups of support blocks 604, and the synchronous connection section 603 is ductile, and a rolling slider 602 that rolls and displaces inside the slide groove 105 is provided at a position of the support block 604 close to the inner side of the filtering and separation box 101, and the top of the support frame 606 and the support block 604 jointly supports an industrial filter cloth 601, and the inner side of the industrial filter cloth 601 is sealed and connected to the outer side of the mounting ring 605, and the industrial filter cloth 601 is elastic, and the industrial filter cloth 601 near the discharge port 106 is guided by the rolling slider 602 to form a concave structure that is inclined downward, and the output end of the concave structure corresponds to the discharge port 106;

[0056] The knocking mechanism 700 also includes a support ring 701 sleeved on the outside of the central axis 200, and a guide groove 702 is arranged on the outside of the support ring 701. The guide groove 702 is a continuous wavy groove structure that fits the outer wall of the support ring 701. Two groups of support slide bars 707 are symmetrically arranged at the bottom of the top plate 103 near the outside of the support ring 701. The outsides of the two groups of support slide bars 707 are respectively sleeved with a first slider 709 and a second slider 712 of symmetrical structure. The first slider 709 and the second slider 712 are provided with a limiting protrusion 711 that is adapted to the guide groove 702 on the side close to the support ring 701. The limiting protrusion 711 drives the first slider 709 and the second slider 712 to be in an up-and-down dislocation distribution state respectively. The first slider 709 and the second slider 712 are both provided with a rack 708 on the side away from the support ring 701.

[0057] A support frame 703 is provided at the bottom of the top plate 103 near the first slider 709 and the second slider 712. A mounting shaft 706 is provided at the bottom of the support frame 703. Two sets of symmetrically distributed first hammers 704 and second hammers 705 are provided on the outer side of the mounting shaft 706. Incomplete gears 710 are provided at the positions of the first hammer 704 and the second hammer 705 near the second slider 712 and the first slider 709 respectively. The incomplete gear 710 is meshed with the rack 708.

[0058] The top of the separation box assembly 100 is provided with an airflow cleaning mechanism 300 which is interconnected with the pneumatic generating mechanism 400. The wind force generated by the airflow impeller 405 drives the airflow to flow through the airflow cleaning mechanism 300 and transport it to the interior of the separation box assembly 100, thereby performing airflow cleaning on the upper and lower end surfaces of the industrial filter cloth 601.

[0059] The airflow cleaning mechanism 300 includes a main air pipe 302 interconnected with the air collecting cylinder 401, and the output ends of the main air pipe 302 are respectively provided with a first air pipe 301 and a second air pipe 303. The output end of the first air pipe 301 extends to the interior of the filtering and separating box 101 and is provided with an upper exhaust port 305 located on the top of the industrial filter cloth 601. The output end of the second air pipe 303 extends to the interior of the filtering and separating box 101 and is provided with a lower exhaust port 304 located at the bottom of the industrial filter cloth 601. The output ends of the lower exhaust port 304 and the upper exhaust port 305 both correspond to the discharge port 106.

[0060] The use process of the separation device for purifying silymarin proposed in this embodiment is as follows: when the device is in use, the silymarin stock solution is transported to the interior of the filtering and separating box 101 through the solution transport pipe 501, and the power of the flow of the silymarin stock solution drives the water flow impeller 403 to rotate to generate mechanical power. Through the guiding effect of the arc-shaped guide plate 502, the silymarin stock solution unidirectionally impacts one side of the water flow impeller 403, thereby driving the water flow impeller 403 to rotate;

[0061] The rotation of the water impeller 403 drives the support shaft 404 to rotate, thereby driving the airflow impeller 405 to rotate and disturb the airflow to flow upward, thereby generating wind force. At the same time, the rotation of the support shaft 404 drives the transmission unit 402 to rotate, thereby driving the central shaft 200 to rotate accordingly.

[0062] The silymarin stock solution transported to the inside of the filtration and separation box 101 through the solution transport pipe 501 is blocked by the baffle 104 and falls to the top of the industrial filter cloth 601 by its own gravity, so as to be filtered through the industrial filter cloth 601, so that the solid and liquid in the silymarin stock solution are separated. After the liquid containing silymarin is filtered through the industrial filter cloth 601, it is concentrated in the inside of the liquid collecting bucket 102 and directed out, while the solid particles such as the broken leaves and seeds of silymarin are retained on the top of the industrial filter cloth 601;

[0063] The rotation of the central shaft 200 drives the support collar 701 and the mounting ring 605 to rotate respectively, and the rotation of the mounting ring 605 drives the support frame 606, the support block 604, and the industrial filter cloth 601 to rotate accordingly, and the support block 604 drives the rolling slider 602 to roll and displace inside the slide 105. At the same time, as the industrial filter cloth 601 rotates, when the industrial filter cloth 601 with the solid particles such as broken leaves and seeds of milk thistle on the top rotates to the position of the clamping discharge port 106, the industrial filter cloth 601 is concave downward by the stretching and guiding action of the rolling slider 602 and the support block 604, thereby forming a concave structure obliquely downward, so that the solid particles such as broken leaves and seeds of milk thistle on the top of the industrial filter cloth 601 automatically slide to the position of the discharge port 106 for discharge;

[0064] When the industrial filter cloth 601 forms a concave structure downward, the industrial filter cloth 601 is stretched because the concave area is larger than the flat area, and thus the industrial filter cloth 601 is in a stretched state, and the synchronous adaptability of the synchronous connection section 603 is stretched at the same time;

[0065] As the support ring 701 rotates, the guide groove 702 rotates. The two groups of limit protrusions 711 are displaced up and down inside the guide groove 702, and the first slider 709 and the second slider 712 are moved back and forth alternately up and down. The first slider 709 and the second slider 712 are moved back and forth up and down, and the rack 708 is moved back and forth up and down by the first slider 709 and the second slider 712. Then, the two groups of meshing incomplete gears 710 are respectively driven to rotate by the two groups of racks 708, and the two groups of corresponding first hammers 704 and second hammers are respectively driven by the rotation of the incomplete gears 710. 705 alternately and reciprocally hammers the top of the industrial filter cloth 601. During the process of hammering the top of the industrial filter cloth 601, since the industrial filter cloth 601 is in a stretched state, the filter gap thereof is enlarged. The fluff burrs stuck in the filter gap are separated out by the inertia of the hammering. The fluff burrs stuck in the filter gap are kept in the upper position due to the inertia, and the industrial filter cloth 601 is displaced downward by the instantaneous hammering, thereby generating separation. Through the effect of the hammering, the separation function of the fluff burrs of the silymarin leaves contained in the silymarin stock solution during the filtration process of the industrial filter cloth 601 is realized;

[0066] Furthermore, the airflow generated by the disturbance of the airflow impeller 405 is transported to the positions of the lower exhaust port 304 and the upper exhaust port 305 through the first air delivery pipe 301, the main air delivery pipe 302, and the second air delivery pipe 303, and is located at the top position of the industrial filter cloth 601 through the upper exhaust port 305, so that the broken leaves and seeds of the milk thistle on the top of the industrial filter cloth 601 are blown by the airflow to the position of the discharge port 106 for discharge;

[0067] At the same time, the silybum leaf fluff separated from the industrial filter cloth 601 is affected by the airflow and discharged toward the position of the discharge port 106;

[0068] The airflow output from the upper exhaust port 305 blows upward from the bottom of the industrial filter cloth 601, and then cooperates with the first hammer 704 and the second hammer 705 to make the silymarin leaf hairs stuck in the filter gap of the industrial filter cloth 601 separate and move upward, so as to prevent the hairs from moving downward and merging into the silymarin liquid due to the increase of the filter gap.

[0069] At the same time, the airflow output from the upper exhaust port 305 cooperates with the airflow output from the lower exhaust port 304 to further promote the discharge of waste from the top of the industrial filter cloth 601;

[0070] During the up-and-down displacement of the first slider 709 and the second slider 712 , the stability of the up-and-down displacement structure of the first slider 709 and the second slider 712 is maintained by the support slide bar 707 .

[0071] Example 2

[0072] like Figure 1 , Figure 2 , Figure 6 , Fig.10 As shown, a separation process for purifying silymarin, the process steps are as follows:

[0073] Step 1: First, the infusion assembly 500 is connected to the external silymarin stock solution pipeline, and the silymarin stock solution is transported to the interior of the separation box assembly 100 for filtration;

[0074] Step 2: Then, the flow force of the silymarin stock solution drives the water flow impeller 403 to generate mechanical power, and simultaneously drives the air flow impeller 405 to rotate to generate wind power;

[0075] Step 3: The industrial filter cloth 601 is driven to rotate by mechanical power to transport the filtered milk thistle residue to the output end of the separation box assembly 100 for discharge;

[0076] Step 4: Using mechanical power to drive the first hammer 704 and the second hammer 705 to hammer the surface of the industrial filter cloth 601 to separate the spicules of the milk thistle leaves;

[0077] Step 5: The wind generated by the rotation of the airflow impeller 405 blows the discharge of the silymarin residue, thereby completing the separation and purification process of silymarin.

[0078] The above describes the specific implementation methods of the embodiments of the present invention, but the embodiments of the present invention are not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the embodiments of the present invention, all of which are protected by the embodiments of the present invention.
