Description

Technical Field

[0001] The invention relates to the technical field of separation equipment, in particular to a bovine serum filtering and purification device. Background Art

[0002] Bovine serum is the most widely used natural culture medium in cell culture. It contains abundant nutrients necessary for cell growth and is often used for in vitro culture of animal cells. It has extremely important functions. When extracting bovine serum, a filtration and purification device is essential.

[0003] The prior art still has the following deficiencies when filtering and purifying bovine serum:

[0004] 1. Before filtering and purifying bovine serum, the serum needs to be removed from the freezer and then placed at room temperature for thorough thawing. During thawing, the serum needs to be shaken evenly to make it uniform and reduce the formation of flocculent precipitates. However, in the prior art, thawing and filtration purification are performed in two separate devices, which not only affects the filtration purification effect, but also makes it easy for the bovine serum to be contaminated with external bacteria when the thawed bovine serum is moved to the filtration purification device.

[0005] 2. During filtration and purification, impurities in the serum tend to adhere to the upper end surface of the filter membrane, thereby forming a layer of impurities, causing the serum filter to be blocked, affecting the filtering effect of bovine serum.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Example 1

[0041] Reference Figure 1 and Figure 2 , filtering and purification equipment, which is used in the field of bovine serum, mainly includes a purification box 1, and a placing bucket 2 is provided on the top of the purification box 1 for holding the serum to be thawed. The internal structure of the purification box 1 is complex and the design is exquisite to meet the multiple needs of serum purification.

[0042] Reference Figure 2 , Figure 4 and Figure 5 A cross tube 18 is provided in the purification box 1, and a plurality of nozzles 19 are fixed at the bottom of the cross tube 18, which are used to spray the serum evenly on the filter 23. In order to achieve uniform spraying of the nozzles 19, a rotating rod 12 is connected to the top of the purification box 1 through a base rotation, and a first rotating disk 13 is fixed at one end of the rotating rod 12, and a second rotating disk 37 is provided at the other end. The design of the first rotating disk 13 and the second rotating disk 37 provides a power source for the subsequent swing and spraying structure.

[0043] Reference Figure 2 At the bottom of one side of the purification box 1, a drain pipe 42 is provided for discharging the serum after being filtered by the filter 23. The filter 23 is fixed in the first rotating ring 24 below the nozzle 19 to ensure that the serum can be sprayed and filtered by the filter 23 smoothly.

[0044] Reference Figure 2-Figure 4 In order to realize the swinging of the placing bucket 2, a swinging structure is designed for this device. The structure includes two support columns 3, which are fixed on the top of the purification box 1 and located on both sides of the bottom of the placing bucket 2. Arc grooves 4 are provided on both sides of the bottom of the placing bucket 2, which slide with the arc guide blocks 5 on the top of the support columns 3 to ensure that the placing bucket 2 can swing smoothly. At the same time, a connecting frame 6 is fixed on the side of the placing bucket 2 close to the vertical rod 9, and a first slide bar 8 is slidably connected in the connecting frame 6, and one end of the first slide bar 8 rotates and penetrates the vertical rod 9. When the vertical rod 9 is raised and lowered, the connecting frame 6 and the first slide bar 8 cooperate to drive the connecting frame 6 to move up and down, thereby realizing the reciprocating swing of the placing bucket 2. The lifting and lowering of the vertical rod 9 is driven by the first turntable 13 through the cooperation of the first fixed frame 10 and the second slide bar 11.

[0045] Specifically, when the rotating rod 12 and the first rotating disk 13 rotate, the first rotating disk 13 pushes the second sliding rod 11 to slide in the first fixed frame 10, thereby driving the vertical rod 9 to move up and down reciprocatingly. The up and down movement of the vertical rod 9, through the cooperation of the connecting frame 6 and the first sliding rod 8, and the cooperation of the arc-shaped guide block 5 and the arc-shaped groove 4, causes the placing bucket 2 to swing back and forth. This swing helps to make the temperature and composition of the serum in the placing bucket 2 uniform and reduce the generation of flocculent precipitates.

[0046] Reference Figure 2 , Figure 4 and Figure 5 In order to realize the reciprocating spraying of serum, the device is also designed with a reciprocating spraying structure. The structure includes a hollow tube 16 rotating on the inner wall of the top of the purification box 1, and a hose 15 is fixed at the bottom of the bucket 2. The bottom end of the hose 15 extends into the hollow tube 16 and is rotatably connected to the hollow tube 16. An arc plate 20 is fixed on the top of the cross tube 18, and an arc hole 21 is provided in the arc plate 20. The bottom end of the vertical rod 9 is sealed and slidably extended into the purification box 1, and a third slide bar 22 is fixed on one side, and the third slide bar 22 is slidably matched with the arc hole 21. When the vertical rod 9 moves up and down reciprocatingly, it will drive the third slide bar 22 to slide in the arc hole 21, thereby driving the arc plate 20 and the cross tube 18 to reciprocate. In this way, the nozzle 19 can evenly spray the serum on the filter screen 23, so that the filter screen 23 can fully filter the serum.

[0047] During operation, the solenoid valve on the hose 15 is first opened, so that the serum in the placing bucket 2 is sprayed onto the filter screen 23 below through the hose 15, the hollow tube 16, the cross tube 18 and the nozzle 19. At the same time, the rotating rod 12 and the first rotating disk 13 continue to rotate, driving the vertical rod 9 to move up and down and the placing bucket 2 to swing back and forth. In this way, the nozzle 19 can evenly cover the surface of the filter screen 23 during the process of spraying the serum, thereby improving the filtering effect.

[0048] Reference Figure 2 and Figure 6 In addition, in order to further improve the filtering effect, the present device is also designed with a shaking structure. This shaking structure can make the filter screen 23 shake during the filtering process, so that impurities flow on the filter screen 23, and prevent impurities from clogging the filter screen 23. The shaking structure includes a plurality of first arc-shaped convex plates 27 fixed to the bottom of the first rotating ring 24, and these first arc-shaped convex plates 27 are evenly distributed and extend along the circumference of the first rotating ring 24. The inner wall of the purification box 1 is fixed with a plurality of second arc-shaped convex plates 28 located below the first arc-shaped convex plates 27, and the second arc-shaped convex plates 28 are also evenly distributed and extend along the circumference of the inner wall of the purification box 1. When the first rotating ring 24 is rotating, the first arc-shaped convex plates 27 will contact and separate from the second arc-shaped convex plates 28. This cooperation allows the first rotating ring 24 to move up and down while rotating.

[0049] Reference Figure 2 and Figure 6 The top of the first rotating ring 24 is connected to the second rotating ring 25 in a longitudinal sliding manner through a sliding groove and a slider. This connection method allows the second rotating ring 25 to slide longitudinally on the first rotating ring 24, while maintaining relative rotation between the two. The top of the second rotating ring 25 is rotatably connected to a fixed ring 26, which is firmly fixed to the inner wall of the purification box 1 to provide stable support for the second rotating ring 25.

[0050] Specifically, when the second rotating ring 25 rotates, it will synchronously drive the first rotating ring 24, the filter screen 23 and the first arc-shaped convex plate 27 to rotate together. During the rotation process, the cooperation between the first arc-shaped convex plate 27 and the second arc-shaped convex plate 28 causes the first rotating ring 24 to shake up and down, thereby driving the impurities on the filter screen 23 to flow, effectively preventing the impurities from clogging the filter screen 23.

[0051] Reference Figure 1 , Figure 4 , Figure 6 and Figure 7 The shaking structure also includes two driving rods 31 that rotate on one side of the purification box 1 through the base, and the two driving rods 31 are respectively located on both sides of the purification box 1. The bottom ends of the driving rods 31 are fixed with a reel 30, and the outer wall of the reel 30 is wound with a pull rope 29. One end of the pull rope 29 is fixed on the reel 30, and the other end extends into the purification box 1 and is fixedly connected to the side of the second rotating ring 25 away from the reel 30. Therefore, when the reel 30 rotates, it will reel in or release the pull rope 29, thereby driving the second rotating ring 25 to rotate.

[0052] Reference Figure 1 and Figure 7Two L-shaped seats 33 are fixed on the top of the purification box 1, and a moving rod 34 is slidably inserted in the L-shaped seats 33. The same third fixed frame 39 is fixed to the ends of the two moving rods 34 that are close to each other. The third fixed frame 39 is used to accommodate and slide with the fourth sliding rod 38 that deviates from the center of the second rotating disk 37. When the second rotating disk 37 rotates, the fourth sliding rod 38 will slide in the third fixed frame 39, thereby driving the third fixed frame 39 and the moving rod 34 to reciprocate.

[0053] Reference Figure 7 The ends of the two moving rods 34 that are away from each other are fixed with a second fixing frame 35, and a rack 36 is fixed to the inner wall of one side of the second fixing frame 35. The top ends of the two driving rods 31 extend into the corresponding second fixing frames 35 and are fixed with gears 32, which mesh with the rack 36. Therefore, when the second fixing frame 35 reciprocates left and right, it drives the driving rod 31 to rotate through the cooperation of the gear 32 and the rack 36.

[0054] Through the above description, we have demonstrated in detail a specific implementation of a bovine serum filtration and purification device. The device effectively avoids the problem of impurities clogging the filter 23 through a clever shaking structure design, thereby improving the purification efficiency and reliability of the device.

[0055] Reference Figure 4 and Figure 7 A driving motor 14 is fixed to the top of the purification box 1 through a frame, and the output shaft of the driving motor 14 is connected to the rotating rod 12 through a synchronous belt and a synchronous wheel.

[0056] When the driving motor 14 is started, it drives the rotating rod 12 to rotate through the synchronous belt and the synchronous wheel. The rotation of the rotating rod 12 will synchronously drive the second rotating disk 37 to rotate, and then drive the second fixed frame 35 and the rack 36 to move back and forth through the cooperation of the fourth sliding rod 38 and the third fixed frame 39. Finally, the second fixed frame 35 drives the two retracting wheels 30 to reciprocate synchronously through the cooperation of the gear 32 and the rack 36. The retracting wheel 30 can reciprocate the second rotating ring 25 by pulling and releasing the pull rope 29, thereby completing the shaking of the filter screen 23.

[0057] Reference Figure 4 In order to ensure that the connection frame 6 can move up and down smoothly without affecting the normal operation of the first slide bar 8, we set clearance grooves 7 on the inner walls of the two sides of the connection frame 6 that are away from each other. Specifically, the two ends of the first slide bar 8 extend into the corresponding clearance grooves 7 respectively, and the clearance grooves 7 and the first slide bar 8 are slidably matched. In this way, when the connection frame 6 moves up and down, the clearance grooves 7 can provide enough space for the first slide bar 8 to avoid interference between the two, ensuring that the first slide bar 8 can continue to play its supporting and guiding role.

[0058] Reference Figure 2 and Figure 5 In order to improve the rotation stability of the hollow tube 16, a U-shaped seat 17 is fixed on the top inner wall of the purification box 1. Specifically, the bottom end of the hollow tube 16 rotates through the U-shaped seat 17, so that the U-shaped seat 17 can provide a stable support point for the rotation of the hollow tube 16, reduce the shaking during rotation, and improve the stability of rotation.

[0059] Reference Figure 2 In the purification box 1, we also designed a transparent inclined panel 40, which is located below the filter screen 23 and is placed at an angle. This transparent inclined panel 40 cooperates with the drain pipe 42 to guide the serum to flow in the direction of the drain pipe 42.

[0060] Specifically, after the filter screen 23 filters the serum, the filtered serum falls on the transparent inclined panel 40 , and then is guided to the drain pipe 42 by the inclined surface of the transparent inclined panel 40 , and is discharged through the drain pipe 42 .

[0061] In addition, a plurality of ultraviolet sterilization lamps 41 are arranged on the transparent inclined panel 40. These ultraviolet sterilization lamps 41 can further sterilize the serum flowing on the transparent inclined panel 40 to ensure the purity and safety of the serum.

[0062] In summary, this equipment achieves efficient filtration and purification of bovine serum through the cooperation of the swing structure, reciprocating spray structure and shaking structure. This equipment not only improves the purification efficiency and quality of serum, but also reduces the generation of flocculent precipitates, providing better protection for the subsequent use of serum.

[0063] Example 2

[0064] refer to Figure 8 and Fig. 9, improved on the basis of Example 1: In order to achieve a fixed connection between the rotating rod 12 and the second rotating disk 37, we fixed a fixing seat 43 on the side of the second rotating disk 37 close to the rotating rod 12, and slidably penetrated an insertion rod 44 in the fixing seat 43. At the same time, a plurality of slots 46 are provided on the outer wall of the rotating rod 12, and these slots 46 and the insertion rod 44 can be plugged in. Specifically, a tension spring 45 is sleeved on the outer wall of the insertion rod 44, the top end of the tension spring 45 is fixedly connected to the outer wall of the insertion rod 44, and the other end of the tension spring 45 is fixedly connected to the top of the fixing seat 43. In this way, under the tension of the tension spring 45, the insertion rod 44 will always maintain a downward trend. When it is necessary to fix the rotating rod 12 to the second rotating disk 37, it is only necessary to align the insertion rod 44 with the slot 46 and insert it. In order to facilitate the operation of the insertion rod 44, we fixed a top plate 47 on the top of the insertion rod 44, and slidably connected a trapezoidal plate 48 on the top of the second rotating disk 37. The trapezoidal plate 48 cooperates with the top plate 47. When the trapezoidal plate 48 is located below the top plate 47, it can support the top plate 47 and prevent the insertion rod 44 from moving downward. When the support for the top plate 47 needs to be released, the trapezoidal plate 48 can be pulled outward. In this way, when the rotating rod 12 and the first rotating disk 13 rotate, if the placing bucket 2 swings or the cross tube 18 rotates, the filter screen 23 will be synchronously driven to shake through the second rotating disk 37, the insertion rod 44 and the top plate 47, thereby further mixing and purifying the serum.

[0065] A method for using a bovine serum filtration and purification device comprises the following steps:

[0066] S1. Put the serum into the placing bucket 2. When the serum needs to be thawed, start the driving motor 14. The driving motor 14 drives the rotating rod 12 and the first rotating disk 13 to rotate through the synchronous wheel and the synchronous belt. The first rotating disk 13 drives the vertical rod 9 to move back and forth up and down through the sliding cooperation of the first fixed frame 10 and the second sliding rod 11. The vertical rod 9 drives the connecting frame 6 to move back and forth up and down through the sliding cooperation of the yielding groove 7 and the first sliding rod 8. Under the cooperation of the arc guide block 5 and the arc groove 4, the connecting frame 6 drives the placing bucket 2 to swing back and forth, so that the temperature and composition of the serum in the placing bucket 2 can be uniform, and the generation of flocculent sediment can be reduced;

[0067] S2. After thawing, the solenoid valve on the hose 15 is opened, and the serum in the placing bucket 2 is sprayed onto the filter screen 23 below through the hose 15, the hollow tube 16, the cross tube 18 and the nozzle 19. During the spraying process, the placing bucket 2 continues to swing. When the vertical rod 9 moves up and down, the cross tube 18 is driven to rotate back and forth through the cooperation of the arc hole 21 and the third slide bar 22, so that the nozzle 19 can evenly spray the serum on the filter screen 23, so that the filter screen 23 can fully filter the serum;

[0068] S3. In addition, when the rotating rod 12 and the first rotating disk 13 rotate, the trapezoidal plate 48 can also be pulled outward to release the support for the top plate 47. The top plate 47 moves downward under the pulling force of the tension spring 45 and is inserted into the slot 46 to fix the rotating rod 12 and the second rotating disk 37. Therefore, the rotating rod 12 synchronously drives the second rotating disk 37 to rotate, and the cooperation of the fourth sliding rod 38 and the third fixed frame 39 drives the second fixed frame 35 and the rack 36 to move back and forth left and right. The second fixed frame 35 drives the two winding wheels 30 to rotate synchronously and reciprocally through the cooperation of the gear 32 and the rack 36. The winding wheel 30 can make the second rotating ring 25 reciprocate by pulling the pull rope 29. The second rotating ring 25 drives the first rotating ring 24, the filter screen 23 and the first arc-shaped convex plate 27 to rotate synchronously. During the rotation process, the cooperation of the first arc-shaped convex plate 27 and the second arc-shaped convex plate 28 causes the first rotating ring 24 to swing up and down, driving the impurities on the filter screen 23 to flow, thereby preventing the impurities from clogging the filter screen 23.

[0069] S4, the serum filtered by the filter 23 falls on the transparent inclined panel 40, and is guided to the drain pipe 42 under the action of the inclined surface of the transparent inclined panel 40, and is discharged by the drain pipe 42. In addition, when the serum flows on the transparent inclined panel 40, the ultraviolet sterilization lamp 41 can further sterilize the serum.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 14 and the ultraviolet germicidal lamp 41 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
