Description

Technical Field

[0001] The present invention belongs to the field of polypeptide preparation, and more specifically, particularly relates to a device for refining and processing polypeptides for cosmetics. Background Art

[0002] At present, with the booming development of the cosmetics industry, consumers' requirements for the efficacy of cosmetics are becoming increasingly stringent. As a highly potential active ingredient, polypeptides are widely used in various high-end cosmetics due to their significant effects such as promoting collagen production, improving skin elasticity, and reducing wrinkles. From anti-wrinkle creams to firming serums, polypeptides can be found everywhere, bringing new breakthroughs to skin care.

[0003] However, the application effect of polypeptides in cosmetics depends to a large extent on their purity and quality. In the crude polypeptide solutions extracted naturally or synthesized chemically, there are often unreacted raw materials, by-products, catalysts, and other impurities. The presence of these impurities may not only reduce the activity of polypeptides and affect the efficacy of cosmetics, but also cause adverse reactions such as skin allergies, severely restricting the further application of polypeptides in the cosmetics field. Existing polypeptide refining and processing technologies have many deficiencies: Firstly, the traditional polypeptide refining and processing device has a single screening effect on polypeptides and cannot fully screen polypeptides from impurities, resulting in unqualified quality of the screened polypeptides. Secondly, when the traditional polypeptide refining and processing device screens impurities in polypeptides through membrane separation technology, the efficiency is low, and after long-term use, polypeptide molecules are likely to adsorb and deposit on the surface of membrane pores, causing the phenomenon of membrane pore blockage.

Detailed implementation manners

[0022] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-14 As shown, in this embodiment, a polypeptide refining device for cosmetics is provided, including a device body 1, the top and bottom of which are respectively connected to a feed port 2 and a discharge port 3, a screen 16, a ceramic membrane 17 and an ultrafiltration membrane 18 are arranged in sequence inside the device body 1 along the direction from the feed port 2 to the discharge port 3, a cover plate 5 is detachably connected to the top of the device body 1, and a vibration component 9 for driving the ceramic membrane 17 to vibrate is arranged on the cover plate 5, and the vibration component 9 includes a first fixed plate 99, which is fixedly connected to the cover plate 5, and a movable plate 97 is rotatably connected to the first fixed plate 99, and both ends of the movable plate 97 are movably connected to a resistance rod 98, and the resistance rod 98 is rotatably connected to the ceramic membrane 17. The contact rod 98 passes through the cover plate 5 and the screen 16, and the ends of the two contact rods 98 facing away from the movable plate 97 can intermittently contact the ceramic membrane 17 in turn. The second fixed plate 93 is fixedly installed on the cover plate 5. The second fixed plate 93 is rotatably connected to the first driving disk 91 through the first rotating shaft 96. The first rotating shaft 96 is driven by the motor 92. The edge position of the first driving disk 91 is rotatably connected to the first end of the driving plate 94. The second end of the driving plate 94 is rotatably connected to the driving rod 95. The end of the driving rod 95 facing away from the driving plate 94 is movably arranged on the movable plate 97 between the first fixed plate 99 and the contact rod 98.

[0026] Specifically, the raw material is first cleaned to remove impurities, and then a crusher is used to break the raw material into smaller particles or fragments for subsequent enzymatic hydrolysis. A specific protease is added to perform enzymatic hydrolysis under suitable temperature, pH value and other conditions to decompose the protein into a polypeptide mixture. The enzymatically hydrolyzed mixture enters a centrifuge, and the centrifugal force generated by high-speed rotation causes insoluble impurities, unreacted solid particles, etc. to precipitate to the bottom of the centrifuge to obtain a relatively clear supernatant containing polypeptides. The supernatant obtained after centrifugation is input into the device body 1 from the feed port 2 through a pump body, and is first filtered through a screen 16 to remove larger particle impurities. Then, the solution reaches the ceramic membrane 17, and the motor 92 drives the first rotating shaft 96 to rotate, and the first rotating shaft 96 drives the first driving disk 91 to rotate, and the driving plate 94 at the edge of the first driving disk 91 moves accordingly, and the driving plate 94 drives the driving rod 95, thereby causing the movable plate 97 to swing back and forth around the rotation connection point with the first fixed plate 99. The abutment rods 98 at both ends of the movable plate 97 will intermittently abut against the ceramic membrane 17 in turn, causing the ceramic membrane 17 to vibrate. The solution filtered by the ceramic membrane 17 is further refined by the ultrafiltration membrane 18 and finally discharged from the discharge port 3. The vibration component 9 vibrates the ceramic membrane 17, which can effectively prevent the ceramic membrane 17 from being blocked, ensure the filtration efficiency and flux, and extend the service life of the ceramic membrane 17. At the same time, the vibration can cause forced convection of the supernatant, reduce the concentration polarization phenomenon, reduce the adsorption and deposition of polypeptide molecules on the surface of the membrane pores, reduce the probability of the membrane pores being blocked, and help to timely remove the attachments on the surface of the membrane pores, maintain the smooth flow of the membrane pores, and ensure the screening efficiency. At the same time, the flow field of the solution on the membrane surface can be more uniform, avoiding the situation where the local flow rate is too low or too high.

[0027] It should be noted that, in this embodiment, in order to avoid damage to the ceramic membrane 17, the length of the abutting rod 98 and the amplitude of movement of the movable plate 97 can be appropriately adjusted. At the same time, according to the characteristics of different polypeptide solutions and refining requirements, sieves 16, ceramic membranes 17 and ultrafiltration membranes 18 with different pore sizes can be selected to adapt to different filtration conditions. Secondly, the supernatant filtered by the ceramic membrane 17 enters the ultrafiltration membrane 18 for screening to further remove impurities with larger molecular weights, so that the polypeptide solution can be more finely separated. Of course, pressure can be applied at the feed port 2 to improve the screening efficiency of the supernatant on the ceramic membrane 17 and the ultrafiltration membrane 18. At the same time, after the screened supernatant is discharged along the discharge port 3, the ultrafiltered polypeptide solution can pass through an ion exchange resin column, and the impurities adsorb to the resin, thereby realizing separation. By changing conditions such as the pH value or ionic strength of the solution, the polypeptide adsorbed on the resin is eluted to obtain a polypeptide solution with higher purity, so as to achieve the refining of the polypeptide. Further, in this embodiment, a controller 14 for controlling the motor 92 is installed on the device body 1, and the rotation speed of the motor 92 can be adjusted by devices such as a frequency conversion controller 14 to adjust the vibration frequency of the ceramic membrane 17. At the same time, a transparent plate 4 for observing the inside of the device body 1 is installed.

[0028] In this embodiment, as Figure 4 and Figure 6 shown, the abutting rod 98 is movably connected to the movable plate 97 through a sixth rotating shaft 23. A third movable groove 24 for the movement of the sixth rotating shaft 23 is provided through the movable plate 97 along its length direction. Specifically, the abutting rod 98 is movably connected to the movable plate 97 through the sixth rotating shaft 23, and the sixth rotating shaft 23 can move in the third movable groove 24. When the movable plate 97 swings, during the process of the abutting rod 98 abutting against the ceramic membrane 17, the connection angle between it and the movable plate 97 can be adaptively adjusted by the movement of the sixth rotating shaft 23 in the third movable groove 24, ensuring that the abutting rod 98 can always better contact the ceramic membrane 17 and transmit vibration. This design of the movable connection and the movable groove increases the flexibility of the movement of the abutting rod 98 and improves the stability and effectiveness of the vibration transmission of the abutting rod 98 to the ceramic membrane 17, avoiding poor contact between the abutting rod 98 and the ceramic membrane 17 due to changes in the swing angle of the movable plate 97.

[0029] In this embodiment, as Figure 6 、 Figure 7 and Figure 9As shown, one end of the resistance rod 98 facing away from the movable plate 97 is fixedly connected with a resistance block 19, and the resistance block 19 is made of flexible material. Specifically, the resistance block 19 made of flexible material can prevent the resistance rod 98 from causing hard damage to the ceramic membrane 17, thereby protecting the integrity of the ceramic membrane 17, extending the service life of the ceramic membrane 17, and ensuring the vibration transmission effect, ensuring that the ceramic membrane 17 can effectively prevent blockage. At the same time, flexible materials with different hardness and elasticity can be selected as the material of the resistance block 19, such as rubber, silicone, etc., and the selection is made according to the material and thickness of the ceramic membrane 17 to achieve the best vibration transmission and protection effect.

[0030] In this embodiment, if Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a scraper 15, which is a frame-shaped structure. The scraper 15 is movably arranged inside the device body 1. The scraper 15 is arranged in contact with the inner wall of the device body 1. A plurality of connecting rods 12 are fixedly connected to the scraper 15. The plurality of connecting rods 12 penetrate and are movably arranged on the cover plate 5. Vertical rods 11 are fixedly connected between the plurality of connecting rods 12. A cross bar 10 is fixedly connected to the vertical rod 11. A driving assembly 8 for driving the cross bar 10 and the scraper 15 to move longitudinally is provided on the cover plate 5. A protective pad 25 that is in contact with the inner wall of the device body 1 is fixedly connected to the outer wall of the scraper 15. A plurality of spoilers 26 are relatively spaced along the length direction of the scraper 15. Specifically, the driving assembly 8 drives the cross bar 10 to move longitudinally. The rod 10 moves longitudinally, and the crossbar 10 drives the connecting rod 12 through the vertical rod 11. The connecting rod 12 then drives the scraper 15 to move longitudinally inside the device body 1. During the movement, the scraper 15 adheres to the inner wall of the device body 1 and scrapes off the impurities attached to the inner wall of the device body 1. The scraper 15 can clean the impurities on the inner wall of the device body 1 in time to prevent the accumulation of impurities from affecting the filtering effect and the normal operation of the device. At the same time, the spoiler 26 on the scraper 15 disturbs the solution, promotes the flow and mixing of the solution inside the device body 1, and improves the filtering effect. It should be noted that the material of the pad 25 can be selected from wear-resistant and corrosion-resistant rubber or plastic materials.

[0031] In this embodiment, if Figure 4 and Figure 5As shown, the driving assembly 8 includes a third fixing plate 84 fixedly installed on the cover plate 5, a second driving disk 83 rotatably connected to the third fixing plate 84 through a third rotating shaft 82. A driving mechanism 81 for driving the third rotating shaft 82 to rotate is provided on the third fixing plate 84. The third rotating shaft 82 is arranged parallel and opposite to the first rotating shaft 96. A fourth rotating shaft 20 is fixedly connected to the edge of the second driving disk 83. The fourth rotating shaft 20 penetrates and is movably arranged on the cross bar 10. A first moving groove 13 for the fourth rotating shaft 20 to move is provided through the cross bar 10 along its length direction. The driving mechanism 81 includes a first gear 812 sleeved on the third rotating shaft 82, and a second rotating shaft 811 rotatably arranged on the third fixing plate 84. A second gear 814 meshing with the first gear 812 is sleeved on the second rotating shaft 811. The second rotating shaft 811 is connected to the first rotating shaft 96 through a belt transmission mechanism 813. Specifically, when the first rotating shaft 96 rotates, the second rotating shaft 811 is driven to rotate through the belt transmission mechanism 813. The second gear 814 on the second rotating shaft 811 meshes with the first gear 812, thereby driving the third rotating shaft 82 to rotate. Since the first gear 812 is sleeved on the third rotating shaft 82, the rotation of the third rotating shaft 82 drives the second driving disk 83 to rotate. The fourth rotating shaft 20 at the edge of the second driving disk 83 moves in the first moving groove 13 of the cross bar 10. As the second driving disk 83 rotates, the fourth rotating shaft 20 drives the cross bar 10 to move longitudinally. The cross bar 10 drives the scraping plate 15 to move longitudinally through the vertical rod 11 and the connecting rod 12. This design of the driving assembly 8 has a simple structure and stable transmission, and can accurately convert the rotational motion of the driving mechanism 81 into the linear motion of the scraping plate 15, realizing the effective driving of the scraping plate 15 and ensuring that the scraping plate 15 can stably clean the inner wall of the device body 1 and agitate the solution. It should be noted that in this embodiment, the moving stroke and speed of the scraping plate 15 can be changed by replacing the second driving disk 83 with different diameters or adjusting the position of the fourth rotating shaft 20 on the second driving disk 83 to meet different working requirements. At the same time, the length and precision of the first moving groove 13 can be designed and processed according to the moving range and precision requirements of the scraping plate 15.

[0032] In this embodiment, as Figure 5 shown, the diameter of the first gear 812 is larger than that of the second gear 814. Specifically, this deceleration design can make the moving speed of the scraping plate 15 more stable and controllable, which is beneficial to better cleaning the impurities on the inner wall of the device body 1, avoiding incomplete cleaning or damage to the inner wall of the device body 1 due to the too fast moving speed of the scraping plate 15. At the same time, the lower rotation speed also helps to reduce the energy consumption and noise during the operation of the equipment.

An exhaust pipe 38 connected to the second chamber 279 is provided on the auxiliary block 31, and one end of the exhaust pipe 38 away from the auxiliary block 31 extends to the outside of the device body 1. The shaft 275 is rotatably arranged in the second chamber 279, and the shaft 275 is fixedly connected to the second chamber 279. There is an auxiliary plate 278 that fits with the inner wall of the second chamber 279, and a sealing gasket 37 that fits with the inner wall of the second chamber 279 is fixedly connected to the auxiliary plate 278. A tension spring 39 is movably provided at one end of the auxiliary plate 278 away from the connecting port 276, and one end of the tension spring 39 that faces away from the auxiliary plate 278 is fixedly connected to the inner wall of the second chamber 279. One end of the shaft 275 extends to the outside of the auxiliary block 31 and is sleeved with a driving gear 274, and a driven gear 273 that meshes with the driving gear 274 is sleeved on the connecting shaft 30.

[0034] Specifically, in this embodiment, when the vibration assembly 9 works, the abutting rod 98 will move. The first end of the linkage rod 272 is fixedly connected to the abutting rod 98, and the second end is movably connected to the piston 277. Therefore, the movement of the abutting rod 98 will be transmitted to the piston 277 through the linkage rod 272, causing the piston 277 to reciprocate in the first chamber 36 of the cylinder 271. When the piston 277 reciprocates in the first chamber 36, since there is a one-way valve 35 in the intake pipe 34, gas can only enter the first chamber 36 from outside the device body 1 through the intake pipe 34. When the piston 277 moves away from the intake pipe 34, the volume of the first chamber 36 increases and the air pressure decreases, and external gas enters the first chamber 36 through the intake pipe 34. When the piston 277 moves towards the intake pipe 34, the volume of the first chamber 36 decreases and the air pressure increases. At this time, the one-way valve 35 closes, and the gas cannot be discharged from the intake pipe 34, but enters the second chamber 279 of the auxiliary block 31 through the communication port 276. The gas entering the second chamber 279 pushes the auxiliary plate 278 to rotate. The sealing gasket 37 fixedly connected to the auxiliary plate 278 ensures the fit between the auxiliary plate 278 and the inner wall of the second chamber 279, preventing gas leakage. When the auxiliary plate 278 rotates, it will stretch the tension spring 39, and the tension spring 39 plays a role in buffering and resetting. When the auxiliary plate 278 rotates to the position of the exhaust pipe 38, the gas is discharged, and the tension spring 39 drives the auxiliary plate 278 to reset, so as to realize the reciprocating rotation of the auxiliary plate 278. The rotation of the auxiliary plate 278 drives the shaft rod 275 to rotate, and the driving gear 274 sleeved on the shaft rod 275 also rotates accordingly. The driving gear 274 meshes with the driven gear 273 sleeved on the connecting shaft 30. The rotation of the driving gear 274 will drive the driven gear 273 to rotate, thereby causing the connecting shaft 30 to reciprocate. A scraping strip 29 that fits with the ceramic membrane 17 is fixedly connected to the connecting shaft 30. The reciprocating rotation of the connecting shaft 30 causes the scraping strip 29 to scrape the surface of the ceramic membrane 17, removing impurities on the surface of the ceramic membrane 17 and preventing the ceramic membrane 17 from being blocked. At the same time, the connecting arc plates 33 on adjacent connecting shafts 30 are movably connected through the auxiliary rod body 32, ensuring the coordination and consistency of the movement of multiple connecting shafts 30. The scraping of the surface of the ceramic membrane 17 by the scraping strip 29 can timely remove impurities and deposits on the surface of the ceramic membrane 17, effectively prevent the ceramic membrane 17 from being blocked, maintain the high filtration flux and filtration efficiency of the ceramic membrane 17, thereby improving the working efficiency and refining effect of the entire polypeptide refining treatment device. The auxiliary assembly 27 cleverly utilizes the movement of the abutting rod 98 in the vibration assembly 9, converts it into the movement of the piston 277 through the linkage rod 272, and then drives the connecting shaft 30 to rotate, realizing the effective utilization of energy, without the need for an additional power source, reducing the energy consumption and cost of the equipment.

[0035] In this embodiment, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 10 andFigure 11 As shown, it also includes a buffer assembly 7, which is arranged on the cover plate 5. The buffer assembly 7 is movably connected to the movable plate 97 through a fifth rotating shaft 21. The fifth rotating shaft 21 is located on the movable plate 97 between the first fixed plate 99 and the abutting rod 98. The movable plate 97 is penetrated with a second movable groove 22 for the fifth rotating shaft 21 to move. The buffer assembly 7 includes a fixed cylinder 71, which is a hollow annular structure with openings at both ends. The fixed cylinder 71 is fixedly connected to the cover plate 5, and the fixed cylinder 71 does not contact the movable plate 97. The first spring 73, the first end of which is fixedly connected to the fixed cylinder 71, and the second end of the first spring 73 is fixedly connected to the fixed cylinder 71. The top plate 72 is movably connected to the movable plate 97 through the fifth rotating shaft 21. Specifically, when the movable plate 97 swings, the fifth rotating shaft 21 moves in the second movable groove 22, and at the same time drives the top plate 72 to compress or stretch the first spring 73. During the swinging process of the movable plate 97, the buffer component 7 plays a buffering role on the swinging of the movable plate 97 through the elastic force of the first spring 73, so that the swinging of the movable plate 97 is more stable. The buffer component 7 can effectively reduce the impact and vibration during the swinging process of the movable plate 97, avoid damage to the ceramic membrane 17 due to excessive swinging of the movable plate 97, and also help to improve the vibration component 9 The stability and reliability of operation can be improved, and the service life of the equipment can be extended; further, an auxiliary mechanism 6 is arranged in the fixed cylinder 71, and the auxiliary mechanism 6 includes a movable ring 62, which is movably arranged between the inner wall and the outer wall of the fixed cylinder 71, and the movable ring 62 is an annular structure. An auxiliary groove 64 for the movable ring 62 to move is arranged in the fixed cylinder 71, and the auxiliary ring 61 is fixedly connected with the movable ring 62, and the auxiliary ring 61 passes through and is movably arranged on the fixed cylinder 71. The auxiliary ring 61 is an annular structure, and the height of the auxiliary ring 61 is less than the height of the auxiliary groove 64. A plurality of second springs 63 are fixedly connected to one end of the movable ring 62 away from the auxiliary ring 61. When When the top plate 72 compresses the first spring 73, the top plate 72 will cause the movable ring 62 to move in the auxiliary groove 64 through the auxiliary ring 61. During the movement of the movable ring 62, the second spring 63 will further buffer and assist the movement of the movable ring 62. When the top plate 72 is away from the fixed cylinder 71, the second spring 63 drives the movable ring 62 and the auxiliary ring 61 to reset. The auxiliary ring 61 can further limit the first spring 73, thereby ensuring the stability of the first spring 73. It should be noted that the movable plate 97 will not contact the fixed cylinder 71 when rotating along the first fixed plate 99, so as to avoid conflict between the two.

[0036] Working principle: First, the raw material is cleaned to remove impurities, and then a crusher is used to break the raw material into smaller particles or fragments for subsequent enzymatic hydrolysis. A specific protease is added to perform enzymatic hydrolysis under suitable temperature, pH value and other conditions to decompose the protein into a polypeptide mixture. The mixed solution after enzymatic hydrolysis enters a centrifuge. The centrifugal force generated by high-speed rotation causes insoluble impurities, unreacted solid particles, etc. to precipitate to the bottom of the centrifuge to obtain a relatively clear supernatant containing polypeptides. The supernatant obtained after centrifugation is input into the device body 1 from the feed port 2 through a pump body, and is first filtered through a screen 16 to remove larger particle impurities. Then, the solution reaches the ceramic membrane 17, and the motor 92 drives the first rotating shaft 96 to rotate, and the first rotating shaft 96 drives the first driving disk 91 to rotate, and the driving plate 94 on the edge of the first driving disk 91 moves accordingly, and the driving plate 94 drives the driving rod 95, thereby causing the movable plate 97 to swing back and forth around the rotation connection point with the first fixed plate 99. The abutment rods 98 at both ends of the movable plate 97 will intermittently abut against the ceramic membrane 17 in turn, causing the ceramic membrane 17 to vibrate. The solution filtered by the ceramic membrane 17 is further refined by the ultrafiltration membrane 18 and finally discharged from the discharge port 3. The vibration component 9 vibrates the ceramic membrane 17, which can effectively prevent the ceramic membrane 17 from being blocked, ensure the filtration efficiency and flux, and extend the service life of the ceramic membrane 17. At the same time, the vibration can cause forced convection of the supernatant, reduce the concentration polarization phenomenon, reduce the adsorption and deposition of polypeptide molecules on the surface of the membrane pores, reduce the probability of the membrane pores being blocked, and help to timely remove the attachments on the surface of the membrane pores, maintain the smooth flow of the membrane pores, and ensure the screening efficiency. At the same time, the flow field of the solution on the membrane surface can be more uniform, avoiding the situation where the local flow rate is too low or too high.
