Description

Technical Field

[0001] This utility model relates to the field of semiconductor technology, and in particular to an assembled experimental auxiliary device and a parallel light reactor. Background Technology

[0002] Photocatalytic reactions, especially those mediated by visible light, have provided a new platform for the synthesis of functional molecules and materials. Compared to traditional thermocatalysis, photocatalytic reactions proceed under mild conditions and can achieve reaction selectivity that is difficult to achieve in thermocatalysis, showing great potential for development. Therefore, photochemical reactions have attracted much attention in the field of synthetic chemistry in recent years.

[0003] The requirements for reactors in photocatalytic reactions differ from those in traditional catalytic reactions. The wavelength and intensity of the light source are additional factors that need to be considered and limited in photocatalytic systems.

[0004] The patent published in CN 215743371 U, entitled "Parallel Light Reactor," discloses: "A parallel light reactor includes several reaction chambers housing reaction tubes, a light irradiation module irradiating the reaction chambers, a stirring module, and a cooling module. The reaction chambers are arranged in a ring. The stirring module is a magnetic stirring mechanism located in the middle of the ring formed by the reaction chambers. The cooling module is an air-cooling mechanism located below the stirring module. It also includes a light-shielding shell. The light irradiation module, stirring module, cooling module, and reaction chambers are integrated inside the light-shielding shell." This parallel light reactor integrates stirring and cooling functions, with a corresponding number of reactor components and functional modules. However, research groups in universities conducting photochemical reaction research often have low-cost, small-scale research needs due to funding and space constraints. Therefore, designing a parallel light reactor that allows for the separate use of the stirring function or the simultaneous use of cooling and stirring functions, with detachable and modular functional modules, is a pressing issue. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an assembled experimental auxiliary device that can be assembled to form one or more functional areas. Functional modules can be assembled according to the actual experimental requirements of the laboratory. After use, the functional modules can be removed to achieve multiple uses, reduce the floor space, eliminate the accumulation of equipment in the laboratory due to space limitations, and reduce experimental costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an assembled experimental auxiliary device, including a base, with a reaction chamber provided above the base;

[0007] A top cover, located at the open end of the reaction chamber, is used to fix the light source and the reaction tube;

[0008] A partition is arranged parallel to the base, dividing the base into a heat dissipation functional area and / or a stirring functional area from bottom to top;

[0009] The heat dissipation functional area, the stirring functional area, and the reaction chamber are connected in sequence.

[0010] The ports of the heat dissipation functional area are open.

[0011] The base includes:

[0012] First mounting plate and second mounting plate;

[0013] The first mounting plate and the second mounting plate are arranged at intervals and are fixed at their ends.

[0014] The first mounting plate has first slots at both ends, and the openings of the first slots are open; the openings of the first slots are located at the edge of the first mounting plate, either near or far from the reaction chamber.

[0015] The second mounting plate has a second slot, and the opening of the second slot is open; the opening of the second slot is located at the edge of the second mounting plate, which is away from or close to the reaction chamber.

[0016] The first mounting plate has a first slot for assembling the first end of the partition.

[0017] The second mounting plate has a second slot for assembling the second end of the partition.

[0018] The top cover has a light source limiting hole at its center; the top cover also has reaction tube limiting holes at equal angles, with the light source limiting hole as the center.

[0019] Ventilation slots are provided on both the first mounting plate and the second mounting plate.

[0020] To solve the above-mentioned technical problems, this utility model also provides a parallel light reactor, including a light source and the above-mentioned assembled experimental auxiliary device.

[0021] The light source is mounted on the top cover;

[0022] A heat dissipation structure is provided in the heat dissipation functional area, and the heat dissipation structure includes a first adjustment knob;

[0023] The stirring functional area is provided with a stirring structure, which includes a second adjustment knob.

[0024] The actuating end of the stirring structure extends into the reaction chamber.

[0025] Preferably, one of the first mounting plates is provided with a first through hole and / or a second through hole; the first adjusting knob extends out of the first through hole; and the second adjusting knob extends out of the second through hole.

[0026] Preferably, the light source includes: a central light source, embedded in a light source limiting hole; and a top light source, positioned above any of the reaction tube limiting holes.

[0027] The beneficial effects of this utility model are as follows: Through modular card-mount structure, flexible functional area division, and standardized positioning design, it achieves advantages such as easy assembly (adopting a plug-in design avoids the application of complex connectors and glue, facilitating processing and assembly while being environmentally friendly and economical, thus contributing to the provision of high-performance products), multi-functional adaptability, and efficient heat dissipation / stirring, significantly improving the convenience of experimental operation and the reliability of results. Specific effects are as follows:

[0028] First, the modular design allows for flexible adaptation to experimental needs: The assembled structure of the base, reaction chamber, top cover, and partitions allows for adjustment of the configuration of the heat dissipation or stirring functional areas according to experimental requirements, improving the device's versatility. The partitioned design of the heat dissipation and stirring functional areas allows for independent control of different experimental steps, such as heat dissipation and cooling or stirring reactions, improving experimental efficiency. The open end design of the heat dissipation functional area allows it to contact the experimental platform, enabling the heat dissipation mechanism to be placed directly on the platform. The base cover is then fastened to the platform, forming an installation area with the platform's desktop. The reaction chamber is connected to the heat dissipation / stirring functional area (the reaction chamber not only improves light utilization but also forms an upward airflow channel with the air-cooled radiator in the functional module, rapidly removing hot air from the system, resulting in high heat dissipation efficiency, which is beneficial for system temperature control and extending the lifespan of the light source). The heat dissipation functional area transmits the flowing airflow through the central connecting hole to the reaction chamber via the stirring functional area. The actuator of the stirring functional area extends into the reaction chamber through the connecting hole, and during operation, it uses rotation combined with magnetic force to attract the magnetic particles in the reaction tube, achieving the purpose of stirring.

[0029] Secondly, it is easy to disassemble and maintain. The first and second mounting plates are fixed by snap-fit, eliminating the need for additional fasteners, simplifying the assembly process, and making it convenient to clean or replace parts.

[0030] Third, it enhances structural adaptability. The modular mounting plate can be adjusted and combined according to experimental needs, and is compatible with functional modules such as partitions of different sizes or heat dissipation structures and stirring structures.

[0031] Fourth, rapid positioning and secure connection: The open slot design of the first slot of the first mounting plate and the second slot of the second mounting plate facilitates the alignment and engagement of adjacent first and second mounting plates, reducing assembly errors and improving assembly efficiency; under the same assembly conditions, if the slot of the first slot is close to the reaction chamber, the slot of the second slot is far away from the reaction chamber, and their positions relative to the reaction chamber are exactly opposite; the open ends of the first and second slots allow them to slide and engage with each other along the slot opening direction, while limiting relative displacement in the horizontal direction to ensure a secure connection.

[0032] Sixth, the partitions are adjustable and the functional areas are flexible: the first and second slots allow the partitions to be inserted or removed horizontally. Based on the partitions separating the height areas of the heat dissipation or stirring functional areas, the slot design prevents the partitions from tilting or loosening, ensuring the stability of the stirring structure in the stirring functional area.

[0033] Seventh, precise positioning of the light source and reaction tube: the light source limiting hole ensures that the light source, such as the LED light panel, is vertically aligned with the reaction tube, improving the uniformity of photocatalytic or photochemical reactions; the reaction tube limiting holes distributed at equal angles allow multiple sets of experiments to be carried out simultaneously, reducing human operation errors; the fixed hole position design ensures that the reaction tube spacing is consistent, avoiding cross-contamination or uneven illumination / temperature, improving data comparability, and the aperture range is suitable for a variety of different experimental needs.

[0034] Eighth, enhanced heat dissipation performance: The ventilation slots facilitate the entry of air from outside the heat dissipation functional area into the heat dissipation structure and promote air circulation inside the base, enhancing the heat dissipation effect. This is suitable for experimental scenarios involving high temperatures or long-term reactions. The ventilation slots promote air circulation inside the base, forming convection with the open end of the heat dissipation functional area, effectively reducing the equipment temperature. The slot design reduces material usage while maintaining the supporting rigidity of the mounting plate, making it suitable for long-term placement.

[0035] Ninth, the combination of the central light source and the top light source significantly improves the light intensity received by the system; by combining the two light sources, the lighting requirements of different systems can be met. In particular, the top light source can directly guide light into the reaction system through optical fiber, which has extremely high efficiency.

[0036] Tenth, through the integrated modular experimental auxiliary device, the reactor is modularly assembled. Users can flexibly match different functional modules (such as heat dissipation, stirring, etc.) according to experimental needs, which significantly improves the versatility of the equipment and experimental efficiency. The top cover directly installs the light source, which is compact in structure and facilitates the maintenance or replacement of the light source, while ensuring the stability of the parallel light path.

[0037] Eleventh, the heat dissipation and stirring functional areas are set up independently. The heat dissipation structure and the stirring structure are controlled by adjustment knobs to avoid functional interference. For example, the heat dissipation airflow does not affect the stirring accuracy, thus improving the repeatability of the experiment. The actuator of the stirring structure extends into the reaction chamber and acts directly on the reaction system to ensure the uniformity of mixing, which is especially suitable for scenarios such as photocatalysis that require homogeneous reactions.

[0038] Twelfth, the first and second adjustment knobs are exposed through the first and second through holes respectively, allowing the operator to quickly start and stop the function without opening the device, reducing human intervention and interference with the reaction environment (such as temperature fluctuations or light changes); the through hole layout is integrated with the mounting plate design, avoiding structural strength loss caused by additional openings, while maintaining a clean appearance.

[0039] Thirteenth, the light source configuration is diversified to meet different needs: LED light panels and top-mounted LED fiber optic light sources can be used in combination. The former provides large-area uniform illumination, while the latter realizes high-energy point light sources (such as light focusing reactions), meeting the light intensity and wavelength requirements of different photochemical reactions; the design of embedding in the light source limiting hole ensures accurate positioning of the light source, avoids light path deviation, and ensures the repeatability of the experiment.

[0040] Fourteenth, after the central light source is embedded in the top cover, its heat can be quickly dissipated through the heat dissipation structure of the heat dissipation functional area, extending the life of the light source and maintaining the stability of light intensity; the top light source is set above the limiting hole of the reaction tube, and can be supported by optical fiber or fixed with an additional bracket, which can reduce the optical path loss of traditional external light sources and improve the light energy utilization rate, especially suitable for micro-reaction systems.

Detailed Implementation

[0046] Specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Existing technologies often feature fixed structures and a lack of modular design. Most existing equipment has an integral structure with low integration of modules such as illumination, stirring, and cooling. Repairing or replacing parts requires complete disassembly, making assembly and maintenance complex and hindering rapid replacement or upgrades. The lamp holders are not removable, resulting in high maintenance costs. The lamp holders in the illumination module are mostly fixed or connected in series. Once a lamp bead or lamp holder is damaged, it is often necessary to replace the entire module or even the whole machine, which is costly and environmentally unfriendly. In existing equipment, the functional modules such as illumination, stirring, and cooling are often scattered or overlapping, leading to concentrated heat and uneven heat dissipation, which affects the stability and service life of the equipment.

[0048] Example:

[0049] An assembled experimental auxiliary device includes a reaction chamber 2 located above a base. A top cover 3 is installed at the open end of the reaction chamber 2. It should be further noted that the partition 4 connected to the base, the reaction chamber 2, and the top cover 3 are assembled sequentially from bottom to top. The partition 4 and the lower space of the reaction chamber 2 form an area to accommodate the actuator of the stirring mechanism. The top cover 3 and the middle and upper spaces of the reaction chamber 2 form a space to accommodate the reaction tube and the light source. The open end of the reaction chamber 2 projected onto one side of the top cover 4 is mirror-finished (e.g., polished, sprayed, or electroplated) or coated with reflective material to improve light reflectivity. The reaction chamber 1 is made of metal, such as stainless steel or aluminum alloy, to provide good reflectivity and heat dissipation performance. The inner wall of the reaction chamber 1 is mirror-finished (e.g., polished, sprayed, or electroplated) or coated with reflective material to improve light reflectivity.

[0050] The parallel light reactor in this design is compatible with two light sources: a central light source 701 and a top-mounted light source 02, both with independent power supply and control devices. The central light source 701 can be an LED light source, equipped with a switch for power supply and control. The light source consists of several LED beads, and its surface is parallel or perpendicular to the vertical central axis of the reaction chamber 2. The top-mounted light source also uses an LED light source, with an optical fiber connector at its top. It is fitted with an optical fiber made of polymethyl methacrylate (PMMA), glass, or quartz material and is placed above the reaction vessel. It can be supported by the optical fiber or fixed with an additional bracket to introduce light into the reaction vessel. During the reaction, one of the light sources can be used alone or both light sources can be used simultaneously.

[0051] When using two light sources simultaneously, their wavelengths should be consistent. The LEDs used have wavelengths of 365nm-940nm. It should be further noted that a light source mounting hole 401 is formed in the center of the top cover 4, and the central light source 701 is embedded in the light source mounting hole 401. The top-mounted light source 702 is fixed above one of the reaction tube limiting holes 302 via fiber optic support or a bracket, depending on experimental needs. The light source limiting hole 301 ensures that the light source, such as the LED light panel, is vertically aligned with the reaction tube, improving the uniformity of photocatalytic or photochemical reactions. The equidistantly distributed reaction tube limiting holes 302 allow multiple experiments to be conducted simultaneously, reducing human error. The fixed hole design ensures consistent spacing between reaction tubes, avoiding cross-contamination or uneven illumination / temperature, improving data comparability. The aperture range is suitable for various experimental needs.

[0052] Specifically, for example, in the cycloaddition reaction catalyzed by visible light, the central light source 701 is preferably a 5W LED corn lamp, and the top LED light source is preferably a 1.5W LED fiber optic lamp. The wavelength range of the light sources is 450-460nm, and the optical fiber is made of PMMA material.

[0053] With the light source set up in the experiment, the reaction tube containing the reactants and magnetic particles extends through the reaction tube limiting hole 302 of the top cover 3 and is housed in the reaction chamber 2. It should be further noted that in this scheme, the reaction chamber 2 is a cylindrical cavity with a height of 70mm and is made of stainless steel. The material of the top cover 3 is preferably multi-layer linden wood board. The top cover 3 can be fixedly connected to the edge of the open end of the reaction tube 2 by screws. This method is simple, reliable, and easy to install and disassemble. The partition 4 that contacts the top cover 3 and the reaction chamber 2 is fixedly connected by screws.

[0054] Depending on the specific requirements of the experiment, the size of the reaction tube may vary. Therefore, in this implementation scheme, the radius of the reaction tube limiting hole 302 ranges from 5mm to 18mm. ， The specific design is as follows, corresponding to the diameters of NMR tubes and 3-12mL sample vials:

[0055] The same top cover 3 has a radius of A (A is 5mm or 16mm or 18mm) and a radius of B (B is 5mm or 16mm or 18mm). The values ​​of A and B are not the same at the same time. The reaction tube limiting holes 302 with radii of A and B are set alternately and are evenly distributed with the light source limiting hole 301 as the center.

[0056] The same top cover 3 has the same radius and is evenly distributed with the light source limiting hole 301 as the center;

[0057] The reaction tube limiting holes 302 with different radii are arranged at intervals on the same top cover 3, and are evenly distributed with the light source limiting hole 301 as the center;

[0058] All of the above top covers 3 can be disassembled and replaced as needed to adapt to different experimental requirements.

[0059] The number of partitions 4 in this embodiment is adjusted according to experimental requirements:

[0060] like Figures 1 to 2 As shown, when the experiment requires light and stirring: the number of partitions is set to one, the opposite ends of the partition 4 are inserted into the first slot 1012 of the first mounting plate 101, and the other opposite ends of the partition 4 are inserted into the second slot 1022 of the second mounting plate 102. The partition 4 is fixed radially. At this time, the base and the partition 4 form a stirring functional area, which is convenient for disassembly and maintenance. The first mounting plate 101 and the second mounting plate 102 are fixed by snap-fit. The first mounting plate 101 and the second mounting plate 102 do not require additional fasteners, simplifying the assembly process and making it convenient to clean or replace parts.

[0061] The stirring functional area is equipped with a stirring structure, which includes a magnet 901, a motor 902, and a stirring speed control device 903. The rotating end of the motor 902 extends into the reaction chamber 2 through a through hole in the middle of the partition 4. The magnet 901 is fixed to the end of the rotating end of the motor 902. The stirring speed control device 903 is connected to the main control circuit of the motor 902. After the motor 902 is powered on, it rotates, and the rotating end of the motor 902 drives the magnet 901 to rotate, which in turn drives the magnet in the reaction tube to rotate. The motor speed is controlled by the second adjustment knob 9031 of the stirring speed control device 903.

[0062] In this embodiment, a Type-C power socket is used to power the stirring structure. Alternatively, a DC5521 or DC5525 socket can be used to power the stirring structure. Mounting holes are provided on the second mounting plate 102 to fix the socket.

[0063] like Figures 3 to 4As shown, when the experiment requires illumination, heat dissipation, and stirring: Two partitions are set up and arranged parallel to each other. The opposite ends of the two partitions 4 are inserted into the corresponding first slots 1012 of the first mounting plate 101. The first slots 1012 are adjusted according to the number of partitions 4. The other opposite ends of the partitions 4 are inserted into the second slots 1022 of the second mounting plate 102. The second slots 1022 are adjusted according to the number of partitions 4. The partitions 4 are fixed radially. At this point, the base and the two parallel partitions 4 form a stirring functional area. The stirring function is the same as described above; the base, the partition 4 set below, and the experimental table form the area where the heat dissipation functional area is located. The heat dissipation functional area is equipped with a heat dissipation structure, which includes a cooling fan 801, a fan speed control device 802, and a first adjustment knob 8021. The main control circuit of the cooling fan 801 is connected to the fan speed control device 802. The fan speed control device 802 is equipped with a first adjustment knob 8021. The preferred diameter of the cooling fan 055 is 80mm. It supports pulse width modulation (PWM) speed control, and the speed is adjusted by the first adjustment knob 8021.

[0064] Preferably, the top cover 3 can also be a polygonal plate structure, preferably 6-18 sides.

[0065] Preferably, both the first mounting plate 101 and the second mounting plate 102 are provided with ventilation slots 6. The ventilation slots 6 facilitate the entry of air from outside the heat dissipation functional area into the heat dissipation structure and promote air circulation inside the base to enhance the heat dissipation effect, making it suitable for experimental scenarios involving high temperatures or long-term reactions. The ventilation slots 6 promote air circulation inside the base, forming convection with the open end of the heat dissipation functional area, effectively reducing the equipment temperature; the slot design reduces material usage while maintaining the supporting rigidity of the mounting plate, making it suitable for long-term placement.

[0066] Preferably, the reaction chamber 2 is connected to the heat dissipation / stirring functional area (the reaction chamber 2 not only improves the light utilization rate, but also forms an upward airflow channel with the air-cooled heat sink in the functional module, which serves as a heat dissipation structure, to quickly exhaust hot air from the system, resulting in high heat dissipation efficiency, which is beneficial for system temperature control and improving the lifespan of the light source). The heat dissipation functional area conducts the flowing airflow through the central connecting hole to the reaction chamber via the stirring functional area.

[0067] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
