Description

Technical Field

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

[0002] Silymarin is an important medicinal ingredient extracted from milk thistle plants, which is widely used in the treatment of liver diseases and the antioxidant field. In its purification process, the effective ingredients need to be separated from the original liquid in the broken plant tissues. Traditional processes usually adopt multi-stage filtration and centrifugal separation. However, the leaf fragments, seed particles and fine villi thorns mixed in the silymarin original liquid are likely to cause blockage of the filtration medium, reducing the separation efficiency. Especially in the continuous production process, the frequent cleaning of the filter cloth and shutdown maintenance seriously restrict the production capacity. At the same time, the residual impurities may affect the purity of the final product.

[0003] Existing filtration devices mostly adopt fixed filter screens or static centrifugal structures, which are difficult to adapt to the complex characteristics of solid particles in the silymarin original liquid. Especially, the leaf villi thorns are easy to embed in the fiber gaps of the filter cloth, causing irreversible blockage and reducing the filtration and purification efficiency. At the same time, manual disassembly and cleaning are required, increasing the time cost. In addition, traditional equipment lacks a dynamic cleaning mechanism and cannot synchronously remove the attached impurities during the filtration process, resulting in a significant decrease in filtration efficiency with the running time. Some improved solutions attempt to introduce mechanical vibration to assist in slag discharge, but it is difficult to balance the vibration intensity and the filter cloth life, and the problem of retention of fine villi thorns cannot be solved. Summary of the Invention

[0015] As a further optimization solution of the present invention, the knocking mechanism further includes a support sleeve ring sleeved outside the central shaft.

[0025] 1. The present invention improves the efficiency and product purity of silymarin purification through the combined action of a filtration mechanism, an air flow cleaning mechanism and a knocking mechanism, and at the same time reduces the maintenance cost and energy consumption. First of all, the dynamic filtration mechanism forms an inclined concave surface automatically during the filtration process through a telescopic industrial filter cloth and a rolling slider structure, expands the filter cloth gap and guides the solid particles to be discharged directionally, effectively solving the problem of filter screen blockage and ensuring continuous production. Secondly, the self-cleaning system combines the knocking mechanism with the air flow back-blowing technology, uses the self-energy of the raw liquid flow to drive the impeller, alternately hammers the filter cloth and synchronously sprays the air flow, thoroughly removes the villous thorns embedded in the fibers, avoids impurity residue, and significantly improves the cleaning efficiency of the filter cloth.

[0026] 2. The present invention adopts an energy recycling design. The mechanical power and air flow generated by the raw liquid flow driving the impeller are directly used for the filtration and cleaning processes without an external power source, and the energy-saving effect is prominent. The air flow cleaning system strengthens the impurity stripping effect through the coordinated action of the upper and lower two-way exhaust ports, ensures the porosity permeability of the filter cloth, and the separated silymarin liquid has a higher purity. The overall structure is modularly designed, taking into account both stability and adaptability, and can flexibly adjust the filter cloth shape and air flow intensity, suitable for complex working conditions of different batches of raw materials. This device realizes the full-process automation of filtration, slag discharge and cleaning, greatly reduces manual intervention, and provides an efficient and sustainable solution for the large-scale production of silymarin.

[0050] As Figures 1 to 5 shown, the input end of the separation tank assembly 100 is connected to an infusion assembly 500.

A baffle 104 corresponding to the output end of the solution delivery pipe 501 is provided at the inner wall position of the filtration and separation tank body 101. The baffle 104 is used to limit and block the silymarin stock solution delivered by the solution delivery pipe 501 into the filtration and separation tank body 101;

[0051] An air - actuating mechanism 400 is provided on the outer side of the infusion assembly 500. The air - actuating mechanism 400 includes a water flow impeller 403 and an air flow impeller 405. The silymarin stock solution flows inside the infusion assembly 500 and drives the water flow impeller 403 to rotate respectively to generate mechanical power, and drives the air flow impeller 405 to rotate through the water flow impeller 403 to generate wind power;

[0052] The air - actuating mechanism 400 further includes a gas - collecting cylinder 401 fixedly connected to the top of the solution delivery pipe 501. The bottom diameter of the gas - collecting cylinder 401 is larger than the width of the solution delivery pipe 501. A support shaft 404 penetrating into the inside of the solution delivery pipe 501 is arranged in the middle of the inside of the gas - collecting cylinder 401. A water flow impeller 403 is arranged on the outer side of the support shaft 404 inside the solution delivery pipe 501. One side of the water flow impeller 403 corresponds to the arc - shaped guide plate 502. An air flow impeller 405 is arranged at the top of the support shaft 404. A transmission unit 402 connected to the central shaft 200 in a transmission manner is arranged on the outer side of the support shaft 404;

[0053] As Figures 1 to 9 shown, a central shaft 200 is arranged in the middle of the separation box assembly 100. A filtering mechanism 600 is arranged on the outer side of the central shaft 200. The filtering mechanism 600 includes an industrial filter cloth 601, and the industrial filter cloth 601 is used for filtering the silymarin stock solution;

[0054] The filtering mechanism 600 further includes a mounting ring 605 sleeved on the outer side of the central shaft 200. The outer side of the mounting ring 605 is connected with support skeletons 606 by universal joints. One end of each support skeleton 606 far from the mounting ring 605 is connected with a support block 604 by a universal joint. A synchronous connection joint 603 is connected between two adjacent groups of support blocks 604. The synchronous connection joint 603 has extensibility. A rolling slider 602 that rolls and displaces inside the chute 105 is arranged at the position of the support block 604 close to the inner side of the filtering and separating box body 101. The industrial filter cloth 601 is jointly supported by the support skeletons 606 and the support blocks 604. The inner side of the industrial filter cloth 601 is hermetically connected with the outer side of the mounting ring 605. The industrial filter cloth 601 has elasticity.

[0055] As Figures 1 to 12 shown, a knocking mechanism 700 is arranged at the position on the outer side of the central shaft 200 close to the top of the filtering mechanism 600. The knocking mechanism 700 includes a first hammer 704 and a second hammer 705. The mechanical power generated by the water flow impeller 403 drives the first hammer 704 and the second hammer 705 to alternately and reciprocally hammer the top of the industrial filter cloth 601;

[0056] The knocking mechanism 700 further includes a support collar 701 sleeved outside the central shaft 200. A guiding groove 702 is provided on the outside of the support collar 701. The guiding groove 702 is a continuous wavy groove structure that fits the outer wall of the support collar 701. Two groups of support sliding rods 707 are symmetrically arranged at the bottom of the top plate 103 near the outside of the support collar 701. Symmetrically structured first sliders 709 and second sliders 712 are respectively sleeved on the outside of the two groups of support sliding rods 707. Limiting protrusions 711 adapted to the guiding groove 702 are provided on the sides of the first slider 709 and the second slider 712 close to the support collar 701. The limiting protrusions 711 drive the first slider 709 and the second slider 712 to be in an up-and-down staggered distribution state. Rack teeth 708 are provided on the sides of the first slider 709 and the second slider 712 away from the support collar 701.

The incomplete gears 710 are meshed with the rack teeth 708.

[0058] An air flow cleaning mechanism 300 is provided at the top of the separation box assembly 100 and is interconnected with the pneumatic generating mechanism 400. The wind generated by the air flow impeller 405 drives the air flow to flow through the air flow cleaning mechanism 300 and be transported into the separation box assembly 100, thereby performing air flow cleaning on the upper and lower end faces of the industrial filter cloth 601.

[0059] The air flow cleaning mechanism 300 includes a main air delivery pipe 302 interconnected with the air collection cylinder 401. The output ends of the main air delivery pipe 302 are respectively provided with a first air delivery pipe 301 and a second air delivery pipe 303. The output end of the first air delivery pipe 301 extends into the interior of the filtration and separation box body 101 and is provided with an upper exhaust port 305 located above the industrial filter cloth 601. The output end of the second air delivery pipe 303 extends into the interior of the filtration and separation box body 101 and is provided with a lower exhaust port 304 located below the industrial filter cloth 601. The output ends of the lower exhaust port 304 and the upper exhaust port 305 correspond to the discharge port 106.

[0060] The usage process of the separation device for silymarin purification proposed in this embodiment is as follows. When the device is in use, the silymarin stock solution is transported into the interior of the filtration and separation box body 101 through the solution delivery pipe 501. The mechanical power is generated by driving the water flow impeller 403 to rotate through the power of the flowing silymarin stock solution. Through the guiding action of the arc-shaped guide plate 502, the silymarin stock solution impacts one side of the water flow impeller 403 unidirectionally, thereby driving the water flow impeller 403 to rotate;

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

[0062] The silymarin stock solution transported into the interior of the filtration and separation box body 101 through the solution delivery pipe 501 is blocked by the baffle 104 and falls to the top of the industrial filter cloth 601 under its own gravity. Thus, filtration is carried out 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 by the industrial filter cloth 601, it is concentrated in the interior of the liquid collection hopper 102 and directed out, while the solid particles such as broken silymarin leaves and seeds 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. The rotation of the mounting ring 605 drives the support framework 606, the support block 604, and the industrial filter cloth 601 to rotate. The support block 604 drives the rolling slider 602 to roll and displace inside the chute 105. At the same time, as the industrial filter cloth 601 rotates, when the industrial filter cloth 601 in the area with solid particles such as broken silymarin leaves and seeds on the top rotates to the position where it clamps the discharge port 106, at this time, the industrial filter cloth 601 is concave downward under the stretching and guiding action of the rolling slider 602 and the support block 604, thereby forming an inclined downward concave surface structure, so that the solid particles such as broken silymarin leaves and seeds on the top of the industrial filter cloth 601 automatically slide to the position of the discharge port 106 and are discharged;

[0064] When the industrial filter cloth 601 forms a concave surface structure downward, since the concave surface area is larger than the plane area, the industrial filter cloth 601 is stretched, and thus the industrial filter cloth 601 is in a stretched state. At the same time, the synchronous connection joint 603 is stretched synchronously and adaptively;

[0065] As the support collar 701 rotates, it drives the guide groove 702 to rotate. The rotation of the guide groove 702 causes the two groups of limit bumps 711 to move up and down inside it, driving the first slider 709 and the second slider 712 to reciprocate up and down alternately. The reciprocating up and down movement of the first slider 709 and the second slider 712 drives the rack 708 to reciprocate up and down. Then, the two groups of racks 708 drive the two meshing incomplete gears 710 to rotate respectively. The rotation of the incomplete gears 710 drives the two corresponding first hammers 704 and second hammers 705 to alternately reciprocate and hammer 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, its filtration gaps increase. Due to the inertia of the hammering, the fluff thorns stuck in the filtration gaps are separated. The fluff thorns stuck in the filtration gaps remain in the upper position due to inertia, while the industrial filter cloth 601 is displaced downward by the instantaneous hammering, resulting in separation. Through the action of this hammering, the separation function of the silybum marianum leaf fluff thorns 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 through the first air pipe 301, the main air pipe 302, and the second air pipe 303 to the positions of the lower exhaust port 304 and the upper exhaust port 305. Since the upper exhaust port 305 is located at the top of the industrial filter cloth 601, the solid particles such as the broken leaves and seeds of silybum marianum at the top of the industrial filter cloth 601 are blown by the airflow to the position of the discharge port 106 and discharged;

[0067] At the same time, the silybum marianum leaf fluff thorns separated from the inside of the industrial filter cloth 601 are affected by the airflow and are discharged towards 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 in cooperation with the action of the first hammer 704 and the second hammer 705, the silybum marianum leaf fluff thorns stuck in the filtration gaps of the industrial filter cloth 601 are separated and displaced upward, preventing the situation where the fluff thorns move downward due to the increase in the filtration gaps and blend into the silymarin liquid;

[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 the waste materials at the top of the industrial filter cloth 601;

[0070] During the up and down movement of the first slider 709 and the second slider 712, the support slide rod 707 maintains the stability of the up and down movement structure of the first slider 709 and the second slider 712.

[0071] Embodiment 2

[0072] AsFigure 1 , Figure 2 , Figure 6 , Figure 10 As shown in Figure 10 , a separation process for silymarin purification has the following process method steps:

[0074] Step 2: Furthermore, drive the water flow impeller 403 to generate mechanical power by the flow force of the silymarin stock solution, and synchronously drive the air flow impeller 405 to rotate to generate wind power;

[0075] Step 3: Drive the industrial filter cloth 601 to rotate by mechanical power, and transport the filtered silymarin residue to the output end position of the separation tank component 100 for discharge;

[0076] Step 4: Drive the first hammer 704 and the second hammer 705 to hammer the surface of the industrial filter cloth 601 by mechanical power to achieve the separation function of the silymarin leaf fluff spines;

[0077] Step 5: Blow the discharge of the silymarin residue by the wind power generated by the rotation of the air flow impeller 405, and thus complete the separation and purification process of silymarin.

The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the embodiments of the present invention, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the embodiments of the present invention.
