TECHNICAL FIELD

[0001] The present application relates to the technical field of supergravity device, in particular to a vortex type supergravity field experimental device. BACKGROUND

[0002] Supergravity refers to the force experienced by an object in an environment far exceeding the acceleration of gravity on Earth. The basic principle of supergravity engineering technology is to use the supergravity condition to strengthen the relative speed and contact area between phases, thereby achieving efficient mass and heat transfer processes and chemical reaction processes. Supergravity multiphase mixing technology is a method of using supergravity environment to improve the efficiency of chemical reactions, mainly used in the fields of biochemical reactions, drug synthesis and material preparation, for example: in the field of biochemical reactions, supergravity multiphase mixing technology can be used to improve the growth rate and metabolic efficiency of microorganisms; in the field of drug synthesis, supergravity multiphase mixing technology can be used to improve the purity and production efficiency of drugs; in the field of material preparation, supergravity multiphase mixing technology can be used to improve the crystallinity and forming efficiency of materials. Since supergravity multiphase mixing technology has a wide range of application scenarios, supergravity multiphase mixing technology is a technology with development potential.

[0003] At present, the existing industrial supergravity device is usually realized by a rotating packed bed, also known as a supergravity machine. The rotating packed bed is a device that strengthens the transfer and mixing process of materials through strong centrifugal force, which is composed of a sealed shell and a coaxially rotating annular packed bed. A liquid distributor is arranged in the middle of the annular packed bed, and liquid enters the packing from the inner ring of the packing. The shell is provided with an air inlet hole on the side, and under the action of the pressure gradient, the gas enters the packing layer from the outer ring of the annular packing. In the liquid filling process, the gas and liquid phases are countercurrently contacted to complete the mass and heat transfer process. By adjusting the rotation speed of the device, a stable and adjustable centrifugal gravity field can be generated, and the liquid is subjected to a large shear force in the gravity field and is pulled into an extremely thin film, a very fine wire and a small drop, thereby greatly increasing the contact area between the device and the liquid, and greatly improving the mass and heat transfer rate.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Hereinafter, the terms "first" and "second" are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "a plurality of" is two or more. In addition, the use of "based on" or "according to" means openness and inclusiveness, because the process, step, calculation or other action "based on" or "according to" one or more stated conditions or values can be based on additional conditions or values beyond the stated values in practice.

[0036] In the field of chemical industry, fluid dispersion and mixing are often required. Uniform fluid dispersion and mixing can provide a good basis for processes such as synthesis reaction, extraction, evaporation, absorption, dissolution and drying.

[0037] The material includes solid stream and liquid material. In the traditional method, the material to be treated is directly placed in a sample tube, and then the material in the sample tube is mixed by direct stirring method. The material in the sample tube is a fluid, i.e. liquid, liquid-solid mixture or gas. The direct stirring method includes magnetic stirring method and mechanical paddle stirring method. Regardless of the magnetic stirring method or the mechanical paddle stirring method, the turbulence degree of the fluid in the sample tube during stirring is not uniform. Compared with the fluid near the stirring paddle or the magnetic stirrer, the fluid near the liquid surface and the inner wall of the container has a smaller turbulence degree, which is not conducive to the dispersion and mixing of the materials. Moreover, the magnetic stirring method and the mechanical paddle stirring method can only ensure the dispersion and mixing degree of the fluid in the bottom space of the sample tube, and a certain radial temperature gradient will be formed, that is, the temperature transfer during stirring can only be realized by the sample tube wall at the bottom and the lower side of the sample tube. The limited heat transfer area of the sample tube limits its heat transfer capacity and effect.

[0038] Therefore, supergravity technology is gradually widely used in chemical industry, environmental protection engineering and other related fields. Supergravity refers to the force that an object experiences in an environment that is much greater than the acceleration of gravity on Earth. The basic principle of supergravity engineering technology is to use the relative speed and contact area between phases under supergravity conditions to achieve efficient mass and heat transfer processes and chemical reaction processes. In chemical reactions, supergravity multiphase mixing technology can improve reaction efficiency by changing the buoyancy, settling velocity and mixing efficiency of substances. For example, in a supergravity environment, solutes in a solution can settle more easily, making it easier for substances in the solution to mix and improve reaction efficiency. Supergravity multiphase mixing technology is a method that uses supergravity environment to improve chemical reaction efficiency, mainly used in biochemical reactions, drug synthesis and material preparation fields, such as: in the field of biochemical reactions, supergravity multiphase mixing technology can be used to improve the growth rate and metabolic efficiency of microorganisms; in the field of drug synthesis, supergravity multiphase mixing technology can be used to improve the purity and production efficiency of drugs; in the field of material preparation, supergravity multiphase mixing technology can be used to improve the crystallinity and molding efficiency of materials. Because supergravity multiphase mixing technology has a wide range of applications, supergravity multiphase mixing technology is a technology with development potential.

[0039] At present, the existing industrialized high gravity device is usually realized by a rotating packed bed, also called a high gravity machine. The rotating packed bed is a device for intensifying the transfer and mixing process of materials by strong centrifugal force, which is composed of a sealed shell and a coaxially rotating annular packing bed. A liquid distributor is arranged in the middle of the packing bed. Liquid enters the packing bed from the inner ring of the packing bed. The shell is provided with air inlet holes. Under the action of the pressure gradient, gas enters the packing bed from the outer ring of the annular packing bed. The gas-liquid phase countercurrent contact in the liquid distribution process completes the mass transfer and heat transfer process. By adjusting the rotating speed of the device, a stable and adjustable centrifugal gravity field can be generated. The liquid is subjected to a large shear force in the gravity field and is pulled into an extremely thin film, a very fine wire and a small drop, so that the contact area between the device and the liquid is greatly increased, thereby greatly improving the mass transfer and heat transfer rate.

[0040] The existing laboratory method usually adopts a magnetic stirring method, a mechanical pulp stirring method, a low-speed rotation or oscillation method to realize the dispersion and mixing of samples. Specifically, in a sample bottle or a round-bottom flask or the like container, the mixing is realized by stirring. Although this method has a simple structure and the sample bottle or the round-bottom flask used as a reactor is easy to clean, the mass transfer and heat transfer performance based on the stirring method is low.

[0041] Although the existing industrial centrifugal high gravity device can greatly intensify the mass transfer and heat transfer performance and has been successfully applied to chemical synthesis reaction, extraction, rectification, evaporation and the like, the centrifugal high gravity device has a large volume, a complex structure and is difficult to clean, and thus cannot be applied to a laboratory with limited operation space, frequently changed research methods and frequently changed test samples.

[0042] The embodiment of the present application provides a vortex type high gravity field experimental device.

[0043] Embodiment 1

[0044] The embodiment of the present application provides a vortex type high gravity field experimental device, as shown in the figure, the vortex type high gravity field experimental device comprises a motor 1, an eccentric shaft 2, a rotating table 3 and a sample tube carrier 4 arranged in sequence from bottom to top. Figure 1

[0045] The motor 1 comprises a rotating shaft. The eccentric shaft 2 is used for connecting the rotating shaft and the center position of the rotating table 3, so that the rotating shaft of the motor 1 is different in axis from the center position of the rotating table 3.

[0046] The eccentric shaft 2 is fixed on the rotating shaft of the motor 1 through an eccentric hole. After the motor 1 works, the rotating shaft drives the eccentric shaft 2 to rotate at a high speed.

[0047] Preferably, the eccentricity of the eccentric shaft 2 is 0.5-20 mm. The rotating speed of the motor 1 is 10-6000 rpm.​

[0048] Wherein, the eccentricity is the distance between the rotating shaft of the motor 1 and the axis of the eccentric shaft 2. The power of the motor 1 is determined according to the load, as long as the motor 1 can be steplessly regulated within the range of 10-6000 rpm. The size of the eccentricity can be determined according to the diameter of the sample tube 5, and is generally 0.5-20 mm.

[0049] The sample tube carrier 4 is fixed on the top of the rotating table 3, and the bottom surface of the sample tube carrier 4 is parallel to the top surface of the rotating table 3, and is perpendicular to the eccentric shaft 2.

[0050] The sample tube carrier 4 is provided with a containing groove or a plurality of containing grooves arranged in parallel, for fixing one sample tube 5 or a plurality of sample tubes 5 arranged in parallel.

[0051] Wherein, the rotating table 3 is made of heat-conducting metal material, and is fixedly arranged on the top of the eccentric shaft 2 to make high-speed eccentric rotation.

[0052] The sample tube carrier 4 is made of heat-conducting metal material, and is detachably arranged on the top of the rotating table 3, and under the joint action of the motor 1, the eccentric shaft 2 and the rotating table 3, drives the material in the sample tube 5 to make high-speed eccentric rotation.

[0053] The sample tube 5 is arranged on the matched sample tube carrier 4, and is used for making high-speed eccentric rotation under the joint action of the motor 1, the eccentric shaft 2, the rotating table 3 and the sample tube carrier 4, and the vortex supergravity motion of the fluid in the sample tube 5 is realized by adjusting the rotating speed of the motor 1. The sample tube 5 is generally made of glass, and relies on the metal sample tube carrier 4 and the rotating table 3 to realize temperature and heat conduction.

[0054] The sample tube 5 is generally a glass test tube, which is not only low in price, but also easy to clean.

[0055] Specifically, the sample tube carrier 4 includes a single sample tube carrier 4 and a plurality of parallel sample tube carriers 4.

[0056] The single sample tube carrier 4 is provided with a containing groove for placing one sample tube 5.

[0057] The plurality of parallel sample tube carriers 4 are provided with a plurality of containing grooves arranged in parallel and at equal intervals, for placing a plurality of sample tubes 5.

[0058] This makes the vortex supergravity field experimental device of the application not only can perform sample mixing operation on one sample tube 5, but also can perform sample mixing on a plurality of sample tubes 5 arranged in parallel at the same time, thereby improving the processing efficiency of the sample.

[0059] For example, the single-sample-tube carrier 4 can hold one 500ml sample tube 5, and the parallel multi-sample-tube carrier 4 can have specifications of 24x8ml, 8x50ml and 96x1ml, etc., namely, the multi-sample-tube carrier 4 holding 24 8ml sample tubes 5 in parallel, the multi-sample-tube carrier 4 holding 8 50ml sample tubes 5 in parallel, and the multi-sample-tube carrier 4 holding 96 1ml sample tubes 5 in parallel.

[0060] The motor 1 further comprises a housing, and the housing and the rotating table 3 are provided with an elastic limiting rod 6.

[0061] As shown in Figure 2 the vortex-type supergravity field experimental device of the present application, when working, the material to be treated is put into the sample tube 5, the sample tube 5 is closed by a plug or a cover, then the sample tube 5 to be treated is fixed on the sample tube carrier 4, and the motor 1 is started. Figure 2 A in the figure is a static state diagram of the sample before the motor 1 starts working; Figure 2 B in the figure is a schematic diagram of the sample when the stirring device is working, and only the axis of the sample tube 5 starts to appear vortex; Figure 3 C in the figure is a schematic diagram when the vortex supergravity state is reached, at this time, the fluid in the sample tube 5 is distributed on the inner wall of the sample tube 5 under the action of the supergravity field and the vortex field, forming a liquid film 8.

[0062] Unlike the supergravity method in industrial applications, the present application does not realize the gravity field by rotating the reactor itself, but places multiple sample tubes 5 on the sample tube carrier 4, and then controls the rotating table 3 to make high-speed off-axis rotation in an eccentric manner, wherein the rotating diameter is 0.1mm-20mm, driving the material in the sample tube 5 on the sample tube carrier 4 to realize the supergravity field.

[0063] In the present embodiment, the elastic limiting rod 6 is arranged between the housing at the top of the motor 1 and the bottom surface of the rotating table 3. The elastic limiting rod 6 comprises at least two sleeve rods and a spring, which are sleeved together, wherein the housing at the top of the motor 1 and the bottom surface of the rotating table 3 are oppositely provided with annular sliding grooves, the two ends of the sleeve rod are respectively slidably connected in the two annular sliding grooves, and the spring is sleeved outside the sleeve rod. The elastic limiting rod 6 is used to limit the relative displacement between the housing and the rotating table 3, and also plays a role of shock absorption.

[0064] Compared with the coaxial high-speed centrifugal rotation supergravity reactor in industrial applications, the fluid in the sample tube 5 of the vortex-type supergravity field experimental device of the present application has more movement perpendicular to the rotation direction, which is helpful to form a small vortex in the sample tube 5, thereby forming a vortex gravity field, and further strengthening the mass transfer and heat transfer in the fluid movement process.

[0065] The vortex type super gravity field experimental device provided by the embodiment of the present application only comprises a motor 1, an eccentric shaft 2, a rotating table 3 and a sample tube carrier 4, and the fluid in the sample tube 5 is realized high-speed eccentric centrifugal rotation movement through the cooperation of the motor 1 and the eccentric shaft 2, which is simple in structure, small in overall device volume, low in manufacturing cost and easy to operate, and is suitable for laboratory application; and the device of the present application is easy to clean when only the sample tube 5 is taken down to clean the sample tube 5.

[0066] The vortex type super gravity field experimental device provided by the embodiment of the present application realizes high-speed eccentric centrifugal movement of the sample tube carrier 4 on the top of the rotating table 3 and the sample tube 5 through the cooperation of the motor 1 and the eccentric shaft 2, and the high-speed eccentric centrifugal rotation movement of the sample in the sample tube 5. The device skillfully superimposes the centrifugal gravity field and the vortex field together in the movement process, realizes the vortex super gravity phenomenon, makes the fluid in the sample tube 5 form a violent turbulent at the liquid surface and the inner wall of the sample tube 5, and with the increase of the rotating speed of the motor 1, the fluid in the sample tube 5 will rise along the inner wall of the sample tube 5 until the top of the inner wall of the sample tube 5, and a dynamic "liquid film distribution" state is formed on the inner wall of the sample tube 5; wherein the height and thickness of the liquid film 8 can be adjusted by adjusting the rotating speed of the motor 1; such adjustable height and thickness liquid film distribution is very valuable, which not only can greatly enhance the turbulent mixing of the working material (i.e. mass transfer enhancement), when the fluid in the sample tube 5 forms the "liquid film distribution" state under the action of the super gravity field, the radial temperature gradient of the fluid in the sample tube 5 will also be greatly reduced, which is more conducive to heat absorption or dissipation, and the entire inner wall of the sample tube 5 can be used as the heat transfer area, which greatly increases the heat transfer area (i.e. heat transfer enhancement).

[0067] That is to say, the vortex type super gravity field experimental device of the present application not only has excellent mass transfer and heat transfer performance of the super gravity field equipment, but also is small in size, simple in structure and easy to clean, and is more suitable for laboratory application.

[0068] Based on the vortex type super gravity field experimental device of the present application, combined with temperature control technology, vacuum technology, dry air or inert protective gas (including nitrogen, argon, helium and the like single gas or mixed gas) can be introduced, various unit operations of multifunctional or single-function instrument equipment in chemical synthesis, solvent extraction, solvent evaporation and freeze drying and other laboratory chemical synthesis work can be designed and realized.

[0069] Embodiment 2

[0071] The temperature control device is installed inside the rotating stage 3 of the eddy current hypergravity field experimental device.

[0072] Specifically, the temperature control device can be an electric heating or cooling device installed inside the rotating stage 3, or it can be a heating or cooling chamber installed inside the rotating stage 3. Through the temperature control device, electric heating or cooling, or external circulation heating or cooling, can be realized to achieve temperature control of the fluid in the sample tube 5.

[0073] In this embodiment, the electric heating device may include an electric heating plate and a temperature controller, with the temperature controller controlling the operation of the electric heating plate; the electric cooling device includes an electronic cooling plate and a temperature controller, with the temperature controller controlling the operation of the electronic cooling plate.

[0074] In the vortex-type hypergravity field chemical synthesis reactor provided in this embodiment of the invention, chemical reaction reagents are added to sample tube 5. The reaction temperature and reaction time are controlled by the temperature control device in the rotating stage 3. The motor 1 is started to put the reaction reagents in the sample tube 5 into a vortex hypergravity field state. The strong vortex can greatly enhance the mass transfer and heat transfer process of sample tube 5. Furthermore, the reaction reagents are distributed in a film-like manner along the inner wall of sample tube 5, which greatly increases the heat exchange area and reduces the radial temperature gradient. This is also extremely beneficial for strong endothermic and strong exothermic reactions.

[0075] Example 3

[0077] The vacuum hood 7 is placed outside the sample tube carrier 4 of the eddy current hypergravity field experimental device.

[0078] The hydrazine cooling device and the vacuum pump are both connected to the vacuum hood 7.

[0079] The vortex-type hypergravity field rapid solvent evaporator provided in this embodiment of the invention operates by starting the hydrazine cooling device and the vacuum pump for vacuum evaporation. For example... Figure 4 As shown, Figure 3 Figure D shows the static state of the sample before motor 1 is started. When motor 1 is started, Figure E shows the sample in sample tube 5 being placed under the action of eddy current hypergravity field, and the sample is distributed in a film shape along the inner wall of sample tube 5. This can greatly increase the evaporation area and heat exchange area, thereby overcoming the disadvantage of slow heat conduction speed under vacuum conditions in existing equipment and greatly improving the evaporation efficiency of the sample.

[0083] The cold trap device and the vacuum pump are both arranged in communication with the vacuum cover 7.

[0084] The external circulation refrigeration device is arranged in communication with the sample tube carrier 4 of the vortex supergravity field experimental device.

[0086] In the pre-freezing process of the rapid freeze dryer, the entire wall of the sample tube 5 participates in heat exchange, so that the pre-freezing speed is extremely fast and very uniform; in the vacuum sublimation process, the sublimation area is greatly increased, the working efficiency of the entire device is improved, and the sample after drying is very uniform, and the quality of the sample after drying is improved.
