Description

Technical Field

[0001] This utility model relates to the field of separation equipment technology, and more specifically, to a tubular ultrafiltration membrane separation device for Epimedium extract. Background Technology

[0002] Epimedium extract is a herbal active beverage made from the traditional and precious Chinese medicinal herb Epimedium using modern bio-extraction technology. As a traditional tonic, the efficacy of Epimedium extract can be traced back to the "Shennong's Classic of Materia Medica." Modern research has further confirmed its multiple benefits: it can gently nourish kidney yang, improving problems such as aversion to cold, fatigue, and lack of energy caused by kidney yang deficiency; it promotes blood circulation, which is beneficial to bone and muscle health, making it suitable for daily maintenance by middle-aged and elderly people; at the same time, the flavonoids it contains have certain antioxidant effects, helping to maintain the balance of bodily functions.

[0003] In the production of Epimedium extract, separation equipment is required to filter impurities. Currently, during the separation process, due to the presence of many large molecular impurities, these impurities are often trapped on the membrane surface, gradually accumulating and forming a concentration polarization layer. This concentration polarization layer significantly reduces the membrane's permeability and separation efficiency, leading to prolonged production cycles and frequent backwashing. This increases production costs and may also affect product safety due to residual cleaning agents, while simultaneously shortening the membrane's lifespan. Therefore, we propose a tubular ultrafiltration membrane separation device for Epimedium extract. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a tubular ultrafiltration membrane separation device for Epimedium extract to solve the current technical problem of easy formation of concentration polarization layer affecting production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tubular ultrafiltration membrane separation device for Epimedium extract, comprising a separation tube, an isolation frame disposed inside the separation tube, and a filter membrane assembly disposed inside the isolation frame; Both ends of the separation tube are provided with connecting flanges. The isolation frame is set inside the separation tube to separate the filter membrane assembly. The isolation frame includes a partition plate and a partition cylinder. The partition cylinder is provided with a flow guiding component, which includes several flow guiding plates. The filter membrane assembly includes symmetrically arranged mounting plates, with an inner support frame between the mounting plates, and an ultrafiltration membrane disposed on the outer surface of the inner support frame.

[0006] Preferably, the partition plate is disposed inside the separation tube, and the partition plate divides the separation tube into a water inlet chamber and a filter chamber. The partition plate is provided with a first water inlet hole that connects the water inlet chamber and the filter chamber.

[0007] Preferably, the separator divides the filter chamber into an outer cavity and an inner cavity, and the separator has an array of second water inlets arranged at equal intervals from top to bottom. The second water inlets connect the outer cavity and the inner cavity, and a plurality of the guide plates are disposed in the second water inlets.

[0008] Preferably, the guide plate includes a first guide section, a second guide section, and a third guide section. The length of the first guide section of the plurality of guide plates is gradually shortened from top to bottom. The first guide section and the second guide section form an arc-shaped plate structure. The first guide section, the second guide section, and the third guide section form a Y-shape. The third guide section is bent downward in an arc shape. A through hole is opened on the third guide section. A large flow channel is formed between the third guide section and the second guide section.

[0009] Preferably, the end of the third guide section is bent upward to form a fourth guide section, which reduces the outlet of the large flow channel. The end of the fourth guide section is provided with a downward-bending fifth guide section, which forms a small flow channel with the second guide section. The inner wall of the second guide section is provided with protrusions.

[0010] Preferably, the ultrafiltration membrane is cylindrical in shape, with an outlet on the mounting plate at the top, and the cross-section of the ultrafiltration membrane is wavy.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a flow guide plate structure, which consists of a first flow guide section, a second flow guide section, a third flow guide section, a fourth flow guide section, and a fifth flow guide section. The length of the first flow guide section gradually shortens from top to bottom, adapting to the spatial characteristics of the inner cavity and ensuring uniform distribution of the extract. The Y-shaped structure and through-hole design allow the liquid to form a splitting impact. The fourth flow guide section narrows the outlet of the flow channel to increase the flow velocity. The fifth flow guide section guides the liquid to impact the surface of the ultrafiltration membrane from top to bottom. Combined with the protrusions on the inner wall of the second flow guide section, the turbulence effect is enhanced, effectively stripping large molecular impurity particles attached to the membrane surface, disrupting the stable formation conditions of the concentration polarization layer, significantly improving the water permeability and separation efficiency of the membrane, shortening the production cycle, reducing the backwashing frequency, extending the service life of the ultrafiltration membrane, and solving the current problem of the easy formation of a concentration polarization layer that affects production efficiency.

[0012] 2. This utility model also improves the separation efficiency by designing an ultrafiltration membrane structure with a wavy cross-section that significantly increases the contact area between the ultrafiltration membrane and the extract, thereby increasing the filtration capacity per unit time. The complex wavy surface makes the liquid flow path more tortuous, enhancing the shearing effect between the liquid and the membrane surface, reducing the deposition and adsorption of large molecular impurities on the membrane surface, and slowing down the regeneration rate of the concentration polarization layer. At the same time, combined with the turbulent impact effect of the flow guiding component, it forms a dual protection of "active flushing plus optimized contact", further reducing backwashing costs, extending the continuous operation time of the equipment, and improving the production stability and product quality of Epimedium extract.

Detailed Implementation

[0015] like Figures 1 to 6 As shown, the present invention relates to a tubular ultrafiltration membrane separation device for Epimedium extract, comprising a separation tube 101, an isolation frame 200 disposed within the separation tube 101, and a filter membrane assembly 400 disposed within the isolation frame 200. Both ends of the separation tube 101 are provided with connecting flanges 102. The isolation frame 200 is provided inside the separation tube 101 to separate the filter membrane assembly 400. The isolation frame 200 includes a partition plate 201 and a partition cylinder 203. A flow guiding assembly 300 is provided on the partition cylinder 203. The flow guiding assembly 300 includes a plurality of flow guiding plates 301. The filter membrane assembly 400 includes symmetrically arranged mounting plates 401, with an inner support frame 402 between the mounting plates 401. An ultrafiltration membrane 403 is disposed on the outer surface of the inner support frame 402. This invention enhances turbulence and improves the scouring force of the liquid flow through the specially shaped guide plate 301 structure, thereby disrupting the conditions for the formation of concentration polarization layer. Combined with the corrugated ultrafiltration membrane 403, it increases the contact area, improves the water permeability and separation efficiency, shortens the production cycle, and reduces the backwashing frequency.

[0016] Specifically, a separator 201 is disposed inside the separation tube 101, dividing the separation tube 101 into an inlet chamber and a filtration chamber. A first inlet hole 202 is provided on the separator 201 to connect the inlet chamber and the filtration chamber. Because the filtration chamber is separated, the extract can be located in the outer chamber after entering through the first inlet hole 202 of the inlet chamber, providing sufficient space for the flow of the extract.

[0017] Furthermore, the separator 203 divides the filtration chamber into an outer cavity and an inner cavity. The separator 203 has an array of equally spaced second water inlets 204 arranged from top to bottom, connecting the outer and inner cavities. Several guide plates 301 are disposed within the second water inlets 204. The arrayed and equally spaced second water inlets 204 ensure that the extract can enter the inner cavity uniformly from different heights and positions, avoiding excessive differences in liquid flow rate between the upper and lower regions of the inner cavity, and ensuring uniform filtration load across all parts of the ultrafiltration membrane 403. The guide plates 301, embedded within the second water inlets 204, guide the extract as it passes through the inlets, adjusting the flow direction and state in advance, preparing for subsequent rinsing of the ultrafiltration membrane 403 surface and suppression of the concentration polarization layer.

[0018] It is worth noting that the guide plate 301 includes a first guide section 302, a second guide section 303, and a third guide section 305. The length of the first guide section 302 of the several guide plates 301 is gradually shortened from top to bottom. The first guide section 302 and the second guide section 303 form an arc-shaped plate structure. The first guide section 302 and the second guide section 303 and the third guide section 305 form a Y-shape. The third guide section 305 is bent downward in an arc shape. A through hole 306 is opened on the third guide section 305. A large flow channel is formed between the third guide section 305 and the second guide section 303. The length of the first guide section 302 gradually shortens from top to bottom, which can adapt to the spatial characteristics of the upper and lower regions of the inner cavity, so that the extract at different heights can obtain differentiated and appropriate guiding force, avoid the imbalance of liquid flow velocity in the upper and lower regions of the inner cavity, and ensure the overall flushing effect of the ultrafiltration membrane 403. The Y-shaped structure of the first guide section 302, the second guide section 303 and the third guide section 305 allows the extract to enter the large flow channel through the guide. In conjunction with the fourth guide section 307, the extract impacts the inner wall of the second guide section 303, enhancing the degree of turbulence.

[0019] It is worth mentioning that the end of the third guide section 305 is bent upward to form a fourth guide section 307. The fourth guide section 307 reduces the outlet of the large flow channel. The end of the fourth guide section 307 is provided with a downward-bending fifth guide section 308. The fifth guide section 308 and the second guide section 303 form a small flow channel. The inner wall of the second guide section 303 is provided with protrusions 304. The fourth guide section 307 can guide the extract entering from the through hole 306, causing the extract to impact the inner wall of the second guide section 303. The protrusions 304 on the inner wall of the second guide section 303 can significantly enhance the turbulence effect. Furthermore, the extraction of extract from the large flow channel into the small flow channel can increase the flow velocity of the extract. Under the action of the second guide section 303 and the fifth guide section 308, the extract impacts the surface of the ultrafiltration membrane 403 from top to bottom, disrupting the liquid flow state on the membrane surface, effectively stripping the initially attached impurity particles, and destroying the stable structure of the concentration polarization layer. This allows the ultrafiltration membrane 403 to remain in a stable filtration state for a long time, reducing the backwash cycle and improving the separation efficiency of the extract.

[0020] It is worth noting that the ultrafiltration membrane 403 is cylindrical in shape, with an outlet on the mounting plate 401 located at the top. The cross-section of the ultrafiltration membrane 403 is wavy. The cylindrical wavy cross-section of the ultrafiltration membrane 403 significantly increases the contact area with the extract, thereby increasing the filtration throughput per unit time, improving filtration efficiency, making the liquid flow path on the membrane surface more complex, enhancing the interaction between the liquid and the membrane surface, reducing impurity adhesion, delaying the formation of the concentration polarization layer, and extending the service life of the ultrafiltration membrane 403.

[0021] Working Principle: This embodiment provides a tubular ultrafiltration membrane separation device for Epimedium extract. In use, the device is first connected to the extract delivery pipeline via connecting flanges 102 at both ends of the separation tube 101. The Epimedium extract to be processed first enters the inlet chamber within the separation tube 101, divided by a partition plate 201. Then, the extract flows into the outer cavity of the filtration chamber through the first inlet hole 202 on the partition plate 201. After initial buffering and distribution in the outer cavity, the extract exits through the second inlet hole 202 arrayed on the partition cylinder 203. 04. The water flows into the inner cavity. At this time, the guide plate 301 in the second inlet hole 204 begins to play a guiding role. Since the length of the first guide section 302 of several guide plates 301 gradually shortens from top to bottom, it can adapt to the spatial characteristics of the upper and lower areas of the inner cavity, so that the extract at different heights can obtain the appropriate guiding force. The extract is guided by the arc-shaped plate structure formed by the first guide section 302 and the second guide section 303, and enters the large flow channel formed by the third guide section 305 and the second guide section 303 through the through hole 306, and then flows into the fourth guide section. Guided by 307, the liquid impacts the protrusion 304 on the inner wall of the second guide section 303, significantly enhancing the turbulence. Simultaneously, the outlet of the large flow channel narrows after passing through the fourth guide section 307, further increasing the flow velocity of the extract as it enters the small flow channel formed by the fifth guide section 308 and the second guide section 303. Finally, under the combined action of the second guide section 303 and the fifth guide section 308, the extract impacts the surface of the ultrafiltration membrane 403 of the filter membrane assembly 400 in the inner cavity from top to bottom. The ultrafiltration membrane 403 is cylindrical with a specific cross-section. The wave-shaped design not only increases the contact area with the extract but also makes the liquid flow path more complex. Combined with the turbulence effect formed by the impact, it effectively disrupts the liquid flow state on the membrane surface, removes initially attached impurity particles, and destroys the stable formation conditions of the concentration polarization layer. This ensures the long-term stable operation of the ultrafiltration membrane 403, reduces the backwashing frequency, and improves the separation efficiency. The effective components in the extract enter the interior of the ultrafiltration membrane 403 through the filtration effect and are then discharged through the outlet on the upper mounting plate 401, completing the filtration and separation process.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
