Description

Technical Field

[0001] The present invention relates to the technical field of dialysis devices, and in particular to a dialysis device for natural product extraction and a use method thereof. Background Art

[0002] Dialysis is a separation method based on the principle of semipermeable membrane sieving. Small molecule substances are driven to diffuse through the concentration difference on both sides of the membrane, while macromolecule substances are retained. Natural products (such as alkaloids, flavonoids, polysaccharides, proteins, etc.) widely exist in organisms such as plants, animals, and microorganisms. As a treasure house of compounds produced by biological metabolism in nature, natural products widely exist in plants, animals, microorganisms, and marine organisms, covering various components such as alkaloids, flavonoids, terpenoids, polysaccharides, proteins, and nucleic acids. Their extraction and separation are key technologies in fields such as the development of natural drugs, the preparation of food additives, and the production of cosmetic raw materials. In the process of natural product extraction, dialysis is a commonly used separation means, and a dialysis device is usually used in the separation process.

[0003] In the prior art, dialysis is often static dialysis, and dialysis is carried out through the concentration difference. The entire dialysis separation process is relatively slow, thus greatly reducing the production and processing efficiency. During dialysis, there is no clear indication of whether dialysis is completed, and processing personnel need to pay attention at all times, making it inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a dialysis device for natural product extraction and a use method thereof.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A dialysis device for natural product extraction, including a main body with a "convex"-shaped groove in cross-section, a functional block fixedly connected to the side wall of the main body, and a mounting block fixedly connected to the inner side wall of the main body; A dialysis mechanism is arranged in the main body. The dialysis mechanism consists of a pressurizing component, a main dialysis component, and a control component. The pressurizing component includes a threaded cylinder, which is rotatably connected through a bearing to the mounting block, and the threaded cylinder is rotatably connected to a second gear through a one-way bearing. A servo motor is fixedly connected to the mounting block through a bracket. The main dialysis component includes a lifting ring, which is hermetically slidably connected to the main body. The control component includes a fixing ring, and a second switch is fixedly connected to the upper surface of the fixing ring; A monitoring mechanism is arranged in the functional block. The monitoring mechanism consists of a sensing component and an alarm component. The sensing component includes a first groove and a second groove, both of which are opened in the functional block. An electromagnet is fixedly connected to the bottom wall of the second groove. The alarm component includes an alarm, which is fixedly connected to the side wall of the main body.

[0006] Furthermore, the pressurizing assembly also includes a pressurizing block, which is slidably and sealed within the main body. The threaded cylinder is threadedly connected to a screw, which is fixedly connected to the upper surface of the pressurizing block. The output shaft of the servo motor is rotatably connected to the bottom wall of the mounting block through a bearing. The output shaft of the servo motor is fixedly connected to a first gear, which meshes with a second gear.

[0007] Furthermore, the main dialysis assembly also includes a feed tube and a balance tube. The feed tube and the balance tube are both fixedly connected to the main body and extend into its interior. Solenoid valves are installed inside the feed tube and the balance tube. The solenoid valves are electrically connected to the servo motor through wires. A membrane frame is detachably connected to the lower surface of the lifting ring by bolts. A dialysis membrane is fixedly connected to the inner wall of the membrane frame.

[0008] Furthermore, the control component also includes a first switch, which is fixedly connected to the inner wall of the main body. Multiple first springs are fixedly connected between the lifting ring and the fixed ring. Multiple electric push rods are fixedly connected to the upper surface of the second gear. A clamping block is fixedly connected to the output end of the electric push rod. The first switch, the second switch, and the electric push rod are electrically connected through wires.

[0009] Furthermore, the sensing component also includes multiple fixed tubes, which are fixedly connected to the top wall of the fixed ring. A sliding column is slidably connected to each fixed tube, and the sliding column is fixedly connected to the lifting ring. A connecting tube is slidably connected to the fixed ring, the main body, and the functional block, connecting the fixed ring to the first groove. A piston is slidably connected to the first groove. Hydraulic oil is filled in the first groove, the fixed ring, the connecting tube, and the fixed tube. A fixed plate is fixedly connected between the two opposite inner sidewalls of the first groove. A sliding rod is slidably connected to the fixed plate. A second spring is fixedly connected between the sliding rod and the fixed plate. Conductive blocks are fixedly connected to the sidewalls opposite the piston to the sliding rod. The conductive blocks are electrically connected to the electromagnet via wires.

[0010] Furthermore, the alarm assembly also includes multiple guide rods, which are fixedly connected to the bottom wall of the second groove. A magnetic block is slidably connected through the guide rods. A switch plate is fixedly connected between the two opposite inner sidewalls of the second groove. A third switch is fixedly connected to the lower surface of the switch plate. The third switch is electrically connected to the alarm via a wire.

[0011] Furthermore, the main body has an operating opening on its side wall, and the main body is connected to a door via a hinge. A transparent glass is fixedly embedded in the side wall of the main body.

[0012] Furthermore, the slide rod and piston are both made of polytetrafluoroethylene, and the conductive block is fixedly connected to the slide rod and piston by insulating glue.

[0013] Furthermore, the transparent glass material is made of alkali-free aluminosilicate, and the surface of the transparent glass is engraved with scale lines.

[0014] This invention also provides a dialysis method for the extraction of natural products, comprising the following steps: S1. Raw material preparation: Pre-treatment and preparation of the raw materials to be dialyzed; S2. Device handling: Open the chamber door and check the dialysis membrane through the operating port for any damage. S3, Feeding: The raw materials are injected into the main body through the feeding pipe, and the amount added is controlled by the scale lines on the transparent glass surface; S4. Dialysis: Pressure dialysis is performed through the pressure assembly and the main dialysis assembly; S5. Monitoring: During step S4, the dialysis status is monitored by a monitoring agency, and the machine is stopped in time after an alarm is triggered. S6. Feeding: After dialysis is complete, open the chamber door and collect the dialysis product.

[0015] The present invention has the following advantages: 1. By pressurizing the raw material during dialysis using a pressurizing component, dialysis is carried out using both concentration and pressure differences, which greatly improves dialysis efficiency and shortens dialysis time. 2. During the pressurization process, as the pressure increases, the lifting ring will descend. When the lifting ring descends to trigger the second switch, pressurization will stop. That is, when the pressure reaches a certain level, pressurization will automatically stop, thus ensuring that the pressure is within a certain range and will not exceed the dialysis membrane's bearing capacity, avoiding damage to the dialysis membrane due to excessive pressure. 3. During dialysis, after pressurization, as the substance passes through the dialysis membrane, the internal pressure will decrease. At this time, the lifting ring will rise until it contacts the first switch, triggering the first switch. Then, the pressure will be increased again to a certain level. That is, after the pressure decreases, it can automatically pressurize to maintain the internal pressure, thereby ensuring dialysis efficiency. 4. The dialysis membrane is connected to the membrane frame, which can be freely disassembled, making the replacement and cleaning of the dialysis membrane more convenient; 5. During dialysis, the monitoring system detects the dialysis progress. When dialysis is basically complete, the pressure is increased again. Since little or no substance passes through the dialysis membrane, the internal pressure change is small, keeping the electromagnet energized until the magnetic block triggers the third switch, causing the alarm to sound. This indicates that dialysis is complete and prompts the staff to proceed to the next step. Monitoring is conducted continuously during dialysis, eliminating the need for constant staff attention and making it more convenient to use. 6. During the use of the equipment, only loading and unloading are required. Pressurization, pressure holding and monitoring can all be completed automatically, which greatly improves the automation level of the equipment, thereby improving the ease of operation and processing efficiency.

Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment Refer to Figure 1-9 , a dialysis device for natural product extraction, including a main body 1 with a "convex" - shaped groove in cross - section, a function block 23 fixedly connected to the side wall of the main body 1, and a mounting block 2 fixedly connected to the inner side wall of the main body 1; A dialysis mechanism is arranged inside the main body 1. The dialysis mechanism consists of a pressurization component, a main dialysis component, and a control component. The pressurization component includes a threaded cylinder 5. The threaded cylinder 5 is rotationally connected to the mounting block 2 through a bearing. The threaded cylinder 5 is rotationally connected to a second gear 8 through a one - way bearing. The setting of the one - way bearing makes it so that when the second gear 8 rotates clockwise, it does not带动 the second gear 8 to rotate, but when it rotates counterclockwise, it can带动 it to rotate together. Thus, it is ensured that when the second gear 8 rotates counterclockwise, the pressing block 7 can be lifted and reset through threaded connection, regardless of the state of the electric push rod 9. A servo motor 3 is fixedly connected to the mounting block 2 through a bracket. The main dialysis component includes a lifting ring 14. The lifting ring 14 is hermetically and slidably connected to the main body 1. The control component includes a fixing ring 17. The upper surface of the fixing ring 17 is fixedly connected to a second switch 20; A monitoring mechanism is arranged inside the function block 23. The monitoring mechanism consists of a sensing component and an alarm component. The sensing component includes a first groove 24 and a second groove 25. Both the first groove 24 and the second groove 25 are opened inside the function block 23. The bottom wall of the second groove 25 is fixedly connected to an electromagnet 32. The alarm component includes an alarm 37. The alarm 37 is fixedly connected to the side wall of the main body 1.

[0020] The pressurization assembly also includes a pressurization block 7, which is slidably and sealingly connected within the main body 1. The pressurization block 7 has protrusions, while the inner wall of the main body 1 has matching grooves (such as...). Figure 2 As shown), the pressure block 7 is limited, allowing it to slide up and down but not rotate. The threaded cylinder 5 is threadedly connected to a screw 6, which is fixedly connected to the upper surface of the pressure block 7. The output shaft of the servo motor 3 is rotatably connected to the bottom wall of the mounting block 2 via a bearing. The output shaft of the servo motor 3 is fixedly connected to a first gear 4, which meshes with a second gear 8. The number of teeth on the first gear 4 is less than the number of teeth on the second gear 8 (e.g., ...). Figure 5 As shown in the figure, the rotation speed of the second gear 8 can be reduced, making the pressurization slower. The torque at the first gear 4 can also be amplified at the second gear 8 to obtain a larger torque. The pressurization dialysis is then performed by the pressure block 7 sliding down, which greatly improves the dialysis efficiency.

[0021] The main dialysis assembly also includes a feed pipe 11 and a balance pipe 12. Both the feed pipe 11 and the balance pipe 12 are fixedly connected to the main body 1 and extend into its interior. The balance pipe 12 ensures that raw materials can be added into the main body 1 more smoothly without being affected by internal pressure. Both the feed pipe 11 and the balance pipe 12 are equipped with solenoid valves 13. The solenoid valves 13 are normally open and close when energized. The solenoid valves 13 are electrically connected to the servo motor 3 through wires. When the servo motor 3 is energized, the solenoid valves 13 are energized simultaneously. The lower surface of the lifting ring 14 is detachably connected to the membrane frame 15 by bolts. The detachable membrane frame 15 makes the cleaning and replacement of the dialysis membrane 16 more convenient. The dialysis membrane 16 is fixedly connected to the inner wall of the membrane frame 15. The dialysis membrane 16 is made of high-pressure resistant membrane materials such as polysulfone (PS) and polyvinylidene fluoride (PVDF) to avoid damage to the dialysis membrane 16 caused by pressure.

[0022] The control assembly also includes a first switch 19, which is fixedly connected to the inner wall of the main body 1. Multiple first springs 18 are fixedly connected between the lifting ring 14 and the fixed ring 17. Multiple electric push rods 9 are fixedly connected to the upper surface of the second gear 8. The electric push rods 9 are electromagnetic push rods that extend when energized and automatically retract when de-energized. A clamping block 10 is fixedly connected to the output end of the electric push rod 9. The clamping block 10 is arc-shaped, and a rubber pad is glued to its side wall near the threaded cylinder 5. When the electric push rod 9 extends, the clamping block 10 abuts against the threaded cylinder 5, at which point the second gear 8 can drive the threaded cylinder 5 to rotate. The first switch 19, the second switch 20, and the electric push rods 9 are electrically connected via wires, and their circuit connection relationship is as follows: Figure 9As shown, pressing the second switch 20 energizes the electric push rod 9. Pressing the first switch 19 again energizes the electric push rod 9, and pressing the second switch 20 again de-energizes it. This cycle repeats. Both the first switch 19 and the second switch 20 are waterproof switches with an IP68 waterproof rating. As pressure is applied, the lifting ring 14 gradually slides down, compressing the first spring 18. As the internal pressure gradually increases, the lifting ring 14 contacts the second switch 20. At this point, the electric push rod 9 is de-energized and retracts, separating the clamping block 10 from the threaded cylinder 5. Due to the one-way bearing, the second gear 8 will rotate relative to the threaded cylinder 5 but will not drive it to rotate, thus stopping the pressure block 7 from sliding down and stopping the application of pressure. The raw material is subjected to dialysis under pressure. As the substances in the raw material pass through the dialysis membrane 16 under the action of concentration and pressure differences, the amount of substances above the dialysis membrane 16 decreases, and the pressure also decreases accordingly. As the pressure decreases, the lifting ring 14 rises under the elastic force of the first spring 18 until the lifting ring 14 rises to contact the first switch 19. At this time, the electric push rod 9 is energized again, causing the threaded cylinder 5 to rotate. Through the threaded connection, the pressure block 7 slides down, and pressure is applied again until the appropriate pressure is reached. The second switch 20 is triggered again to stop the pressure application. This cycle of pressure dialysis is repeated to ensure dialysis efficiency while ensuring the pressure is applied in a timely manner, avoiding damage to the dialysis membrane 16, and ensuring dialysis efficiency.

[0023] It is worth mentioning that the present invention uses a method of repeated pressurization for pressurized dialysis, which can greatly reduce the pressure required for pressurized dialysis. By repeatedly pressurizing for dialysis, the dialysis efficiency is ensured, while avoiding the damage to the internal substances of the raw material caused by excessive pressure in the single pressurization dialysis method.

[0024] The sensing component also includes multiple fixed tubes 21, which are fixedly connected to the top wall of the fixed ring 17. A sliding column 22 is slidably connected to each fixed tube 21, and the sliding column 22 is fixedly connected to the lifting ring 14. A connecting tube 26, which is square, is slidably connected to the fixed ring 17 and the first groove 24. A piston 27 is slidably connected within the first groove 24. Hydraulic oil is filled into the first groove 24, the fixed ring 17, the connecting tube 26, and the fixed tube 21. A fixed plate 28 is fixedly connected between the two opposing inner sidewalls of the first groove 24. A sliding rod 29 is slidably connected through the fixed plate 28. A second spring 30 is fixedly connected between the sliding rod 29 and the fixed plate 28. Conductive blocks 31 are fixedly connected to the sidewalls of the sliding rod 29 and the piston 27 on the opposite side. The conductive blocks 31 are electrically connected to the electromagnet 32 ​​through wires. When the conductive blocks 31 make contact, the electromagnet 32 ​​is energized. The sliding column 22 causes the lifting ring 14 to drive the piston 27 to move, and also limits the movement of the lifting ring 14. To prevent rotation and ensure stable up-and-down sliding, the lifting ring 14 descends, simultaneously causing the sliding column 22 to slide down. The sliding column 22, via hydraulic oil, drives the piston 27 upwards. The upward movement of the piston 27 brings it into contact with the sliding rod 29, causing it to slide upwards as well. This also brings the two conductive blocks 31 into contact, energizing the electromagnet 32. The energized electromagnet 32 ​​generates a magnetic repulsion force on the magnetic block 33, causing it to slowly slide upwards. However, dialysis is not yet complete, and some substances continue to pass through the dialysis membrane 16. As the amount of material above decreases, the pressure drops, causing the lifting ring 14 to slide upwards. This upward movement of the lifting ring 14 causes the piston 27 to slide downwards, resulting in the separation of the two conductive blocks 31. The electromagnet 32 ​​is then de-energized. After de-energization, the electromagnet 32 ​​is essentially an iron core, at which point the magnetic block 33 will exert a magnetic attraction on it. Under the action of the magnetic attraction, the magnetic block 33 will slide back to its original position. That is, if dialysis is complete, the magnetic block 33 cannot reach the third switch 35. The dialysis status is monitored by changes in pressure, thus eliminating the need for manual monitoring by staff.

[0025] The alarm assembly also includes multiple guide rods 36, which are fixedly connected to the bottom wall of the second groove 25. A magnetic block 33 is slidably connected to each guide rod 36. When the electromagnet 32 ​​is energized, it generates a magnetic repulsion force on the magnetic block 33. The surface of the guide rods 36 is covered with damping pads, creating frictional resistance between the guide rods and the magnetic block 33, causing the magnetic block 33 to slide slowly under the magnetic force, rather than rapidly. A switch plate 34 is fixedly connected between two opposing inner walls of the second groove 25. A third switch 35 is fixedly connected to the lower surface of the switch plate 34. The third switch 35 is electrically connected to the alarm 37 via a wire. Pressing the third switch 35 activates the alarm 37. When the device is pressurized after dialysis, only a small amount of material or no material passes through the dialysis membrane 16. After pressurization, the pressure above the dialysis membrane 16 will not change significantly. At this time, the lifting ring 14 will not rise further after pressurization, so that the conductive block 31 is always in contact and the electromagnet 32 ​​is always energized, so that the magnetic block 33 keeps sliding upward until the third switch 35 is triggered. The alarm 37 is energized and alarms. When the staff hears the alarm sound, it means that dialysis is complete and the next step can be carried out. After dialysis is completed, the device can automatically alarm to remind the staff, so that the staff does not need to pay attention to the dialysis situation all the time, making the device more convenient to use.

[0026] An operation port 38 is provided on the side wall of the main body 1. The main body 1 is connected to a door 39 by a hinge. The operation port 38 makes it easier to operate inside the main body 1 and to replace and clean the dialysis membrane 16. A pipe for injecting dialysis fluid (not shown in the figure) is provided on the door 39. Dialysis fluid for dialysis is injected into the other side of the dialysis membrane 16 through this pipe. A transparent glass 40 is fixedly embedded in the side wall of the main body 1. The transparent glass 40 makes it easier for staff to observe the internal substances and have a certain understanding of the internal dialysis situation.

[0027] Both the slide rod 29 and the piston 27 are made of polytetrafluoroethylene (PTFE). The conductive block 31 is fixedly connected to the slide rod 29 and the piston 27 with insulating glue. The PTFE slide rod 29 and the piston 27 have good insulation and strength, which can effectively prevent the conductive block 31 from mis-conducting.

[0028] The transparent glass 40 is made of alkali-free aluminosilicate glass. Alkali-free aluminosilicate glass does not contain alkali metals and has excellent heat resistance, mechanical strength and chemical stability after tempering. The transparent glass 40 has engraved scale lines on its surface, which allows the processing personnel to more clearly understand the amount of internal substances.

[0029] This invention also provides a dialysis method for the extraction of natural products, comprising the following steps: S1. Raw material preparation: Pre-treatment and preparation of the raw materials to be dialyzed; S2. Device handling: Open the door 39 and check the dialysis membrane 16 through the operation port 38 to check for any damage. S3, Feeding: The raw material is injected into the main body 1 through the feed pipe 11, and the amount added is controlled by the scale lines on the surface of the transparent glass 40; S4. Dialysis: Pressure dialysis is performed through the pressure assembly and the main dialysis assembly; S5. Monitoring: During step S4, the dialysis status is monitored by a monitoring agency, and the machine is stopped in time after an alarm is triggered. S6. Feeding: After dialysis is completed, open the chamber door 39 and collect the dialysis product.

[0030] In this invention, the material to be dialyzed is added into the main body 1 through the feed tube 11. The amount of material inside is observed through the transparent glass 40. An appropriate amount of material is added according to the scale line. After the material is added, the required dialysis solution is injected into the main body 1 through the box door 39, and then the device is powered on.

[0031] After the device is powered on, the solenoid valve 13 is closed, creating a sealed space above the dialysis membrane 16. At the same time, the servo motor 3 and the electric push rod 9 are powered on, and the electric push rod 9 extends, causing the clamping block 10 to abut against the threaded cylinder 5. The servo motor 3 rotates when powered on, driving the first gear 4 to rotate. The rotation of the first gear 4 drives the second gear 8, which meshes with it, to rotate. At this time, the second gear 8 can drive the threaded cylinder 5 to rotate through the clamping block 10. The rotation of the threaded cylinder 5 causes the screw 6 to drive the pressure block 7 to slide down through the threaded connection, thus pressurizing the raw material.

[0032] As pressure is applied, the lifting ring 14 gradually slides down and compresses the first spring 18. As the internal pressure gradually increases, the lifting ring 14 contacts the second switch 20. At this time, the electric push rod 9 is de-energized and retracts, and the clamping block 10 separates from the threaded cylinder 5. Due to the one-way bearing, the second gear 8 will rotate relative to the threaded cylinder 5 and will not drive it to rotate, so that the pressure block 7 stops sliding down and the pressure is stopped, allowing the raw material to be dialyzed under pressure.

[0033] As the substances in the raw material pass through the dialysis membrane 16 under the influence of concentration and pressure differences, the amount of substances above the dialysis membrane 16 decreases, and its pressure also decreases. As the pressure decreases, the lifting ring 14 rises under the elastic force of the first spring 18 until it contacts the first switch 19. At this time, the electric push rod 9 is energized again, causing the threaded cylinder 5 to rotate. Through the threaded connection, the pressure block 7 slides down, and pressure is applied again until the appropriate pressure is reached. Then, the second switch 20 is triggered again, and the pressure is stopped. This cycle repeats to perform pressurized dialysis.

[0034] As the lifting ring 14 descends, it also drives the sliding column 22 to slide down. The sliding column 22 drives the piston 27 to slide up via hydraulic oil. The piston 27 slides up and contacts the sliding rod 29, causing it to slide up as well. At the same time, the two conductive blocks 31 come into contact, which in turn energizes the electromagnet 32. The energized electromagnet 32 ​​generates a magnetic repulsion force on the magnetic block 33. Under the action of the magnetic repulsion force, the magnetic block 33 slowly slides up. Since dialysis is not yet complete, there is still some substance passing through the dialysis membrane 16. As the amount of substance above the dialysis membrane 16 decreases, its pressure will decrease, causing the lifting ring 14 to slide up. The upward movement of the lifting ring 14 causes the piston 27 to slide down, which in turn causes the two conductive blocks 31 to separate. The electromagnet 32 ​​is de-energized. After the electromagnet 32 ​​is de-energized, it is essentially an iron core. At this time, the magnetic block 33 will generate a magnetic attraction force on it. Under the action of the magnetic attraction force, the magnetic block 33 will slide back to its original position. That is, if dialysis is complete, the magnetic block 33 cannot reach the third switch 35.

[0035] When pressurization is applied after dialysis, only a small amount or no substance passes through the dialysis membrane 16. After pressurization, the pressure above the dialysis membrane 16 will not change significantly. At this time, the lifting ring 14 will not rise after pressurization, so that the conductive block 31 is always in contact and the electromagnet 32 ​​is always energized, so that the magnetic block 33 keeps sliding upward until the third switch 35 is triggered and the alarm 37 is energized. When the staff hears the alarm sound, it means that dialysis is complete and the next step can be carried out.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
