Description

Technical Field

[0001] This utility model relates to the field of bioengineering technology, specifically to a biotechnology solution extraction and separation device. Background Technology

[0002] Biotechnology refers to the science and technology of using living organisms to produce useful substances or improve their composition, thereby enhancing biological characteristics, reducing costs, and creating new species. It encompasses various fields such as human medicine, the environment, and agriculture. In biotechnology research and development, solutions are commonly used research reagents, requiring extraction and separation devices to separate mixed solutions. Extraction is a method of extracting a solute from a solution composed of two immiscible solvents by utilizing the difference in solubility of the solute in those solvents.

[0003] A search revealed existing technology (application number: CN202421829127.X), which describes a system comprising "a base, a mixing extraction and separation structure, and a driving structure. The mixing extraction and separation structure is mounted on the base, and the driving structure is also mounted on the base. The mixing extraction and separation structure includes a support frame, a shaft seat, a rotating shaft, a fixed ring seat, a mixing extraction and separation tank, a sealing cap, a thin tube, a valve, a mixing mesh plate, and a pulley. The support frame is mounted on the base, the shaft seat is fixedly mounted on the support frame, the rotating shaft is rotatably mounted on the shaft seat, and the fixed ring seat is fixedly mounted on the rotating shaft." This utility model effectively solves the problem that most biotechnology solution extraction and separation devices require initial shaking extraction followed by transfer to a separation device for static separation. The shaking transfer process easily causes liquid spillage, resulting in waste and affecting extraction efficiency.

[0004] However, while existing technologies have solved the problem of liquid spillage and waste during the oscillation transfer process, which also affects extraction efficiency, they still have some shortcomings: they cannot be disassembled, making it inconvenient to clean the inside of the mixing extraction separation tank, and the filter screen cannot be replaced.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a biotechnology solution extraction and separation device, including: a support frame 1, a separator 2 fixedly mounted on the support frame 1, a cylinder 3 fixedly mounted above the support frame 1, the cylinder 3 driving a separation component to move up and down, the separation component including a cover 16, a baffle 14 below the support frame 1, a baffle 2 15 below the baffle 14, and a liquid inlet 19 penetratingly connected to the cover 16, the baffle 14, and the baffle 2, and the baffle 14 and the baffle 2 slidably connected to the separator 2.

[0033] In this embodiment, the separation component and the separator constitute a biotechnology solution extraction and separation device according to this application.

[0034] Understandable, Figure 1 The diagram only schematically illustrates some of the components of the separator; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the separator can also include, compared to Figure 1 More or fewer parts.

[0035] Furthermore, in this embodiment, the support frame 1 provides stable support for the entire device, and the cylinder 3 at the top serves as a power source, driving the separation component to move up and down, thereby opening and closing the separating tank 2, which facilitates cleaning the inside of the separating tank 2 or replacing parts. Baffle 14 and baffle 25 slide along the inner wall of the separating tank, cooperating with the liquid inlet 19 to achieve precise injection of the extract.

[0036] Specifically, a motor 4 is installed above the support frame 1. The output shaft of the motor 4 is fixedly connected to the drive wheel 5. The drive wheel 5 is installed above the baffle 14. The drive wheel 5 meshes with the driven wheel 6, and the driven wheel 6 meshes with the driven wheel 7.

[0037] In this embodiment, the output shaft of the motor 4 mounted above the support frame 1 is fixedly connected to the driving wheel 5. The driving wheel 5 drives the driven wheel 6 to rotate through meshing, and the driven wheel 6 drives the driven wheel 7 to mesh and rotate, forming a three-stage gear transmission chain. All gears are located above the baffle 14, completely isolated from the solution reaction area below, ensuring stable power transmission and preventing solution splashing or leakage from causing corrosion and contamination to the transmission components, thus meeting the cleanliness requirements of biological experiments.

[0038] Specifically, a drive shaft 8 is fixedly connected to the bottom of both the drive wheel 5 and the driven wheel 7. A stirring paddle 9 is fixedly connected to the bottom of the drive shaft 8 by bolts. A fixing block 10 is provided on both the drive shaft 8 and the stirring paddle 9. The fixing block 10 is located above the baffle 15. The fixing block 10 is fixed on both sides by bolts, and hexagonal nuts are threaded to both the upper and lower ends of the bolts.

[0039] In a preferred embodiment, a drive shaft 8 is fixedly connected to the lower part of both the driving wheel 5 and the driven wheel 7. The lower end of the drive shaft is tightly connected to the stirring paddle 9 by bolts. A fixing block 10 is provided at the connection between the drive shaft and the stirring paddle. Bolts are threaded to both ends of the fixing block 10, and hexagonal nuts are screwed into both ends of the bolts for double locking. This prevents the connection from loosening due to high-frequency vibration during stirring, further restricts the radial wobble of the drive shaft, and ensures that the stirring paddle always maintains coaxiality when rotating.

[0040] Example 2:

[0041] Specifically, the stirring paddle 9 passes through and is rotatably connected to the baffle 15, and the two sets of stirring paddles 9 rotate in opposite directions inside the separatory tank 2.

[0042] In this embodiment, both sets of stirring paddles 9 extend into the separatory tank 2 through the baffle 15, and the two sets of stirring paddles rotate in opposite directions. The counter-rotating stirring paddles can create convective vortices within the separatory tank 2, breaking the layering interface between the solution and the extractant, significantly increasing the contact area between the two phases, accelerating the distribution balance of the solute between different phases, making the solution mix more uniform, and improving the extraction efficiency. The fit between the baffle 2 and the stirring paddles is sealed with a fluororubber sealing ring, which allows the stirring paddles to rotate freely while preventing the solution inside the tank from leaking upwards to the upper transmission and baffle area.

[0043] Specifically, baffle 14 and baffle 215 are slidably connected to sliding grooves 12 on both sides of the inner wall of the separator 2 by sliding blocks 13 fixed at both ends.

[0044] With this configuration, the sliding blocks 13 at both ends of the baffle 14 and the baffle 2 are provided with sliding grooves 12 on both sides of the inner wall of the separator 2 to match the sliding blocks. The sliding blocks are embedded in the sliding grooves to form a stable sliding fit structure, which allows the baffles to move smoothly up and down along the sliding grooves. The fit between the sliding blocks and the sliding grooves ensures the stable movement of the separation components.

[0045] Example 3:

[0046] Specifically, telescopic rods 20 are symmetrically arranged on both sides of cylinder 3. The upper end of the telescopic rod 20 is fixedly connected to the support frame 1, and the lower part of the telescopic rod 20 is fixedly arranged above the cover 16.

[0047] The cylinder 3 has symmetrical telescopic rods 20 on both sides. The upper end of the telescopic rod is fixedly connected to the support frame 1, and the lower end is rigidly connected to the cover 16 of the separation component, forming a three-point support lifting structure with the cylinder as the center and the two telescopic rods as auxiliary. When the cylinder drives the cover to move up and down, the telescopic rods on both sides extend and retract synchronously, which can counteract the tilting torque caused by the shift of the center of gravity of the cover in real time, ensuring that the cover always remains horizontal and tightly fits the port of the liquid separator, avoiding sealing gaps.

[0048] Specifically, the separator 2 is equipped with an observation window 18, and the bottom of the separator 2 is connected to an outlet pipe 17, which is equipped with a valve 11.

[0049] In this embodiment, an observation window 18 is embedded in the side wall of the separatory tank 2. The observation window 18 is made of highly transparent and corrosion-resistant quartz glass. The operator can monitor the mixing state and the position of the layer interface of the solution in the tank in real time through the observation window 18, accurately determine the endpoint of the extraction reaction, and avoid incomplete separation or loss of target product due to blind operation. A liquid outlet pipe 17 is connected to the center of the bottom of the separatory tank. A valve 11 is installed on the liquid outlet pipe. By adjusting the opening of the valve, the discharge rate can be controlled to achieve separate collection of the layered solutions and reduce cross-contamination between different phase solutions.

[0050] In actual use, the motor output shaft drives the drive wheel 5 to rotate. The drive wheel meshes with the driven wheel 6, which in turn drives the driven wheel 7 to rotate. This causes the transmission shaft 8 connected below the drive wheel and the driven wheel 7 to rotate synchronously, thereby driving the two sets of stirring paddles 9, which extend into the separatory tank through the baffle 15, to rotate in opposite directions. The counter-rotating stirring paddles can create convective vortices in the separatory tank, significantly increasing the contact area between the solution and the extractant, accelerating solute distribution, and achieving efficient mixing and extraction.

[0051] During the process, the solution to be extracted and the extractant are injected into the separatory tank 2 through the inlet 19. The motor 4 above the support frame 1 is started, and the motor output shaft drives the drive wheel 5 to rotate. The drive wheel meshes with the driven wheel 6, which in turn drives the driven wheel 7, causing the transmission shaft 8 connected below the drive wheel and the driven wheel 7 to rotate synchronously. This, in turn, drives the two sets of stirring paddles 9, which extend into the separatory tank 2 through the baffles 15, to rotate in opposite directions. The counter-rotating stirring paddles 9 create a convective vortex within the separatory tank, significantly increasing the contact area between the solution and the extractant, accelerating solute distribution, and achieving efficient mixing and extraction. The operator can monitor the mixing state and stratification of the solution in the tank in real time through the observation window 18 on the separatory tank 2 to determine the extraction progress. After extraction is complete, the valve 11 on the outlet pipe 17 at the bottom of the separatory tank is opened, and the discharge rate is controlled according to the solution stratification to complete the separate collection of different phase liquids. When it is necessary to clean the separatory tank or replace the agitator, the cylinder 3 above the support frame is activated. The cylinder 3 drives the separation component to move up and down along the sliding groove 12 on the inner wall of the separatory tank 2 via the sliding block 13, thereby separating the separation component from the separatory tank 2 and facilitating subsequent maintenance operations. The telescopic rods 20 on both sides of the cylinder ensure that the separation component remains horizontal when it moves, ensuring sealing and structural stability.

[0052] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0053] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
