Description

Technical Field

[0001] This invention relates to the field of photocatalytic reaction technology, specifically to a fully automated photocatalytic reaction platform and its catalytic method. Background Technology

[0002] Photocatalysis, as a highly efficient and environmentally friendly green technology, has shown broad application prospects in various fields such as organic pollutant degradation, new energy development, and antibacterial disinfection. Its core principle is to use a specific light source to excite photocatalytic materials to produce reactive species with strong redox properties, thereby driving the target chemical reaction. With the continuous deepening of research in the field of photocatalysis, researchers are increasingly demanding higher levels of automation, reaction stability, data accuracy, and the ability to conduct multiple parallel experiments on photocatalytic reaction equipment.

[0003] Currently, multi-channel experiments are difficult to conduct. Most devices can only perform a single photocatalytic reaction at a time, resulting in low experimental efficiency. The few devices that support multiple reactions suffer from mutual interference of light between reaction channels and inconsistent reaction conditions. The devices also have insufficient sealing performance, making them prone to coolant leakage and other problems. Furthermore, the low level of automation, with operations such as test tube handling and reaction process control relying on manual labor, further reduces experimental efficiency and safety.

[0013] Beneficial effects

[0014] The present invention has the following beneficial effects: 1. This fully automated photocatalytic reaction platform uses five sets of circumferentially equidistant xenon lamp components as the light source. Combined with a refractive prism, the light is precisely refracted onto the quartz test tube, ensuring sufficient and directional light for the photocatalytic reaction. The reflector assembly on the outside of the xenon lamp head further improves light utilization. Simultaneously, the optical power meter probe inside the outer casing can detect the intensity of the refracted light in real time, providing accurate illumination data to support the experiment and ensuring consistent illumination conditions across different batches of experiments.

[0015] 2. This fully automated photocatalytic reaction platform consists of a complete cooling circulation system composed of an ice machine, a water-cooled circulation machine, and a water pipe module. The water inlet pipe of the water pipe module is connected to the ice machine. By injecting circulating water into the quartz reaction tank, this cooling method has a wide coverage area, which can make the temperature of each area in the quartz reaction tank uniform and avoid local overheating from affecting the reaction process.

[0016] 3. This fully automated photocatalytic reaction platform supports multi-channel parallel experiments, significantly improving experimental efficiency. Relying on the coordinated operation of the rotating and photocatalytic components, a speed-regulating motor drives the main and auxiliary fixed wheels to rotate. The bottle clamps at the top of the auxiliary fixed wheels can stably hold multiple sets of quartz test tubes, supporting up to ten sets of catalytic reactions simultaneously, significantly improving experimental efficiency. Furthermore, the protective cover can shield each set of quartz test tubes, preventing the xenon lamp light source from passing through the quartz reaction cell and interfering with test tubes in other channels.

[0022] Please see Figure 1-8This invention provides a technical solution: a fully automatic photocatalytic reaction platform, including an outer casing 1 and an ice machine 8. The ice machine 8 is connected to the interior of the outer casing 1 via a water pipe. A reaction chamber platform 7 is provided on the top of the outer casing 1. A fixed protective cover 2 is movably provided on the top of the reaction chamber platform 7. An axial flow fan 3 is provided on the inner side of the fixed protective cover 2. Mounting platforms 19 are equidistantly arranged on the surface of the reaction chamber platform 7. A light source assembly is provided on the mounting platform 19. A support base 11 is provided at the center of the reaction chamber platform 7. A quartz reaction cell 17 is provided on the top of the support base 11. A photocatalytic assembly is provided inside the quartz reaction cell 17. A mounting frame 9 is provided on the top surface of the reaction chamber platform 7 and between the light source assemblies. A rotating assembly is provided at the bottom of the mounting frame 9. The rotating assembly is movably arranged inside the quartz reaction cell 17 and works in conjunction with the photocatalytic assembly.

[0023] Specifically, the light source assembly includes a xenon lamp holder 12, a xenon lamp head 13, and a refractive prism 29. The xenon lamp holder 12 consists of five sets arranged equidistantly in a circle on the surface of the mounting platform 19. The xenon lamp holder 12 is detachably mounted to the mounting platform 19 by bolts. The xenon lamp head 13 is fixedly mounted on the side of the xenon lamp holder 12. The refractive prism 29 is fixedly mounted on the top surface of the reaction chamber platform 7 by a mirror frame. The refractive prism 29 and the xenon lamp head 13 are arranged on the same straight line.

[0024] In this embodiment, a light source assembly is used to provide light to the quartz test tube inside the protective cover 25 of the photocatalytic assembly, thereby completing the photocatalysis. The xenon lamp holder 12 is a centralized power module that provides power to the xenon lamp head 13. A reflector assembly is fitted on the outside of the xenon lamp head 13. The refracting prism 29 is used to refract the light emitted by the xenon lamp head 13 to the quartz test tube inside the protective cover 25. The outer casing 1 is equipped with a light power meter probe to detect the intensity of the light refracted by the refracting prism 29, thereby understanding the light intensity in real time and providing real-time data for the photocatalytic experiment. It should be noted that the size of the light spot emitted by the xenon lamp head 13 is adjustable. The specific adjustment method can refer to the existing technology. The xenon lamp holder 12 and xenon lamp head 13 used in this device are: Lamp House R300-3J and CERMAX LX175 / LX300.

[0025] Specifically, the photocatalytic component includes an auxiliary fixing wheel 23, a bottle clamp 24, and a protective cover 25. The quartz reaction cell 17 is sealed and fixedly installed on the top of the support base 11. The auxiliary fixing wheel 23 is movably disposed inside the quartz reaction cell 17. The bottle clamp 24 is fixedly installed on the top of the auxiliary fixing wheel 23. The protective cover 25 is disposed on the inner side of the auxiliary fixing wheel 23.

[0026] In this embodiment, the quartz test tube is inserted into the bottle clamp 24 through the round hole 16 at the top of the main fixing wheel 15, with most of the quartz test tube located inside the protective cover 25. The bottle clamp 24 is used to clamp and limit the quartz test tube to ensure stability, and to ensure that the quartz test tube will not shake or collide when the auxiliary fixing wheel 23 rotates. The protective cover 25 is used to shield the quartz test tube, thereby ensuring that the light source irradiated by the xenon lamp head 13 does not completely pass through the quartz reaction cell 17 to avoid affecting other quartz test tubes inside the protective cover 25.

[0027] Specifically, a photoelectric module 14 is provided on the outside of the support base 11, a protective rotating wheel 18 is movably provided on the top of the support base 11, and several sets of mounting holes 22 are opened on the top surface of the support base 11.

[0028] In this embodiment, a photoelectric module 14 is set to detect whether there is a quartz test tube below the pick-up and place door 4. When the photoelectric module 14 detects that there is a quartz test tube in front of the photoelectric module 14, the photoelectric module 14 transmits a signal to the control device. The control device sends an electrical signal to the pad linear module 5 and the stepper motor 6 and executes the action command to open the pick-up and place door 4, so as to take out the quartz test tube placed inside the protective cover 25. The support base 11 is provided with a protective rotating wheel 18 to protect the auxiliary fixed wheel 23. When the auxiliary fixed wheel 23 rotates under the drive of the main fixed wheel 15 and the speed regulating motor 10, it will rotate along the inner circle of the quartz reaction cell 17. The protective rotating wheel 18 plays a limiting and protective role to avoid collision with the inner wall of the quartz reaction cell 17. The mounting hole 22 on the top of the support base 11 is used for the insertion and installation of the water pipe module 20. The Teflon gasket at the connection between the quartz reaction cell 17 and the support base 11 is used to ensure the sealing of the connection.

[0029] Specifically, the inner ring of the support base 11 is supported by a support rod, and a motor mounting bracket is provided on the surface of the inner ring. A rotating electromagnetic assembly 21 is fixedly installed on the motor mounting bracket.

[0030] In this embodiment, a rotating electromagnetic assembly 21 is used to stir the reagent in the quartz test tube. Specifically, a magnetic stirring particle is placed in the quartz test tube, and then the motor in the rotating electromagnetic assembly 21 is energized to drive the magnetic poles on the rotating electromagnetic assembly 21 to rotate, thereby driving the magnetic particle in the quartz test tube to stir the reagent. The motor in the rotating electromagnetic assembly 21 is electrically connected to the control module box 27.

[0031] Specifically, the bottom of the quartz reaction tank 17 is provided with several sets of water pipe modules 20, wherein the water pipe module 20 includes an inlet pipe, an outlet pipe, and an overflow prevention pipe. The inlet pipe is connected to the ice machine 8, and the outlet pipe is connected to an external water pipe. The ice machine 8 uses existing technology, and the optional model is LC-LTC-5 / 10. The outer casing 1 contains a voltage regulator module 26, a control module box 27, and a water-cooled circulator 28, all of which are existing technologies. The voltage regulator module 26, the control module box 27, and the water-cooled circulator 28 are all fixedly connected to the inner bottom wall of the outer casing 1. Without specifically disclosing the specific structure of the voltage regulator module 26, the control module box 27, and the water-cooled circulator 28, this device can still achieve its function.

[0032] In this embodiment, a water pipe module 20 is set up to inject circulating water into the quartz reaction tank 17. The inlet pipe and outlet pipe are connected to the water-cooled circulator 28, which is then connected to the ice machine 8, thereby forming a complete cooling circulation system.

[0033] Specifically, the rotating assembly includes a speed-regulating motor 10, a main fixed wheel 15, and a circular hole 16. The speed-regulating motor 10 is located at one end of the mounting bracket 9. The output end of the speed-regulating motor 10 is fixedly connected to the top end of the main fixed wheel 15 by screws. The circular holes 16 are equidistantly opened on the surface of the main fixed wheel 15. The main fixed wheel 15 is fixedly connected to the photocatalytic assembly.

[0034] In this implementation scheme, a mounting bracket 9 is set up to install the speed-regulating motor 10. The speed-regulating motor 10 is executed by action commands. The speed-regulating motor 10 drives the main fixed wheel 15 to rotate, which in turn drives the auxiliary fixed wheel 23 to rotate, realizing multi-channel photocatalytic experiment. This device supports up to ten groups of catalytic reactions.

[0035] A catalytic method for use in a fully automated photocatalytic reaction platform includes the following steps: S1. Power on the equipment to put it into operation, and inject cooling water into the quartz reaction tank 17 through the ice machine 8 and the water cooling circulation machine 28. S2. Based on S1, by executing commands to the linear module 5 of the pad block and the stepper motor 6, the pick-up and put-away door 4 is activated, making the pick-up and put-away door 4 open. Then, the quartz test tube containing reagents and magnetic particles is inserted manually or by a robotic arm into the protective cover 25 set inside the auxiliary fixed wheel 23 through the round hole 16 opened on the main fixed wheel 15. S3. Based on S2, power on the light source component to put it into working condition. Adjust the power, light spot size, and light intensity of the light source component according to the experimental requirements. S4.
