Description

Technical Field

[0001] This utility model relates to the field of photochemical reactions, and in particular to an integrated, adjustable photochemical reaction device. Background Technology

[0002] Traditional photochemical reaction devices lack built-in cooling, meaning they cannot dissipate heat from the light source or control the temperature of the reaction liquid within the reactor. Poor heat dissipation can easily lead to light intensity attenuation, affecting the photochemical reaction's effectiveness. Furthermore, the unstable temperature within the reactor, with its large temperature fluctuations, can easily cause side reactions and impurities, impacting experimental and research outcomes. While external cooling equipment can be connected for temperature control, the inability of the photochemical reaction device to integrate and control external equipment prevents timely feedback and automatic online adjustments for abnormal situations. This increases the uncontrollability of the reaction process, easily resulting in inconsistent and non-reproducible results, ultimately reducing research efficiency and accuracy.

[0048] Preferred, such as Figure 6 and Figure 7 As shown, the heat sink 311 of the light source is a polygonal prism, and multiple light source lamp plates 312 are fixedly installed on multiple outer wall surfaces around the heat sink 311. The heat sink 311 has at least one cooling channel 3112 inside, and two heat sink coolant inlets 3111 are spaced apart at its top. The heat sink coolant inlets 3111 are downwardly inclined tubes, and the cooling channel 3112 is a U-shaped channel. One end of each of the two heat sink coolant inlets 3111 is connected to two openings at the top of the cooling channel 3112, and the other end is a pagoda connector connected to the cooling mechanism 2.

[0051] Preferred, such as Figure 3As shown, it also includes a magnetic stirring mechanism 5, which includes a stirring motor 501 and a stirring magnet assembly 502. The stirring motor 501 is fixedly installed on the bottom surface of a horizontally arranged partition 107 inside the housing 1. Its output shaft passes vertically upward through the partition 107 and is connected to the stirring magnet assembly 502. The stirring magnet assembly 502 is magnetically connected to a magnetic stir bar disposed inside the photochemical reaction mechanism 3, driving the magnetic stir bar to rotate.

[0052] It should be noted that in this embodiment, the stirring magnet assembly 502 is disposed below the refrigerant storage tank 221; The magnetic stir bar is located at the bottom of the interior of the reactor 316, and the stirring magnet assembly 502 is existing technology, so its specific structure is not described in detail in this embodiment.

[0053] The advantages of adopting the above preferred solution are: the stirring motor is conducive to driving the stirring magnet assembly to rotate, and the magnetic connection between the stirring magnet assembly and the magnetic stir bar is conducive to driving the magnetic stir bar to rotate, thereby stirring the reaction liquid in the reactor evenly.

[0054] The following section introduces the joint debugging and control: like Figures 1 to 7 As shown, on one hand, the control board 4 controls the compressor 211 to start, driving the gaseous refrigerant to the condenser 212 to liquefy it. After liquefaction, it forms liquid refrigerant. Under the continuous drive of the compressor 211, the liquid refrigerant enters the buffer tank 214 for storage, and part of it enters the evaporator 215 to vaporize. Vaporization absorbs heat, thus cooling the coolant in the refrigerant storage tank 221. The sensor fixedly installed on the inner wall of the refrigerant storage tank 221 monitors the temperature of the coolant in the refrigerant storage tank 221 in real time and transmits the temperature information to the control board 4. The control board 4 adjusts the operating frequency of the compressor 211 according to the temperature signal monitored by the sensor until the temperature of the coolant in the refrigerant storage tank 221 is adjusted to the first preset temperature value. Since the reaction vessel 316 is immersed in the coolant in the refrigerant storage tank 221, the reaction liquid in the reaction vessel 316 will eventually reach the first preset temperature value through heat conduction and complete the photochemical reaction under the illumination of the LED light source 3122. On the other hand, when the temperature of the coolant in the coolant storage tank 221 is adjusted to the first preset temperature value, or during the process of decreasing to the first preset temperature value, the control board 4 controls the circulation pump 222 to start, continuously pumping the coolant in the coolant storage tank 221 to the cooling channel 3112 through the pipe and the coolant interface 3111 of the heat sink, and finally back to the coolant storage tank 221. During the flow of the coolant in the cooling channel 3112, it continuously absorbs the heat generated by the LED light source 3122 and the heat transferred through heat conduction, cooling the LED light source 3122. During this process, the light source temperature acquisition device 3123 monitors the temperature value of the LED light source 3122 in real time and transmits it to the control board 4. The control board 4 then adjusts the flow rate of the circulation pump 222 according to the temperature signal monitored by the sensor until the temperature value of the LED light source 3122 is adjusted to the second preset temperature value. Furthermore, during the photochemical reaction, if the temperature value of the LED light source 3122 monitored by the light source temperature acquisition device 3123 exceeds the preset alarm value, and the temperature value of the LED light source 3122 cannot be reduced within a certain period of time, the control board 4 disconnects the power supply to the LED light source 3122, turns off the LED light source 3122, and outputs an alarm signal on the display screen 102 to avoid damage to the LED light source 3122.

[0055] This embodiment has the following beneficial effects: 1. The first and second cooling components facilitate water cooling of the LED light source, enabling convenient, efficient, and uniform heat dissipation. 2. By adjusting the output flow rate of the circulating pump, the heat dissipation temperature of the LED light source under different working conditions can be dynamically adjusted to maintain the optimal working condition of the LED light source and improve its service life. 3. The reactor is built into the refrigerant storage tank, and the inlet and outlet of the heat dissipation circulation pipe of the LED light source are also connected to the refrigerant storage tank at the same time, realizing dual cooling and temperature control functions, improving utilization, making the integration higher, the operation more convenient, and the energy saving more. 4. The multi-station design allows for simultaneous screening and testing of multiple light sources in different wavelength bands, or testing of multiple parallel samples under the same test conditions, which improves testing efficiency, enables rapid screening and verification of predetermined test conditions, saves testing time, and makes testing more efficient. 5. The power supply and heat dissipation interfaces of each LED light source are designed for quick plug-in and unplugging, which can realize quick replacement of LED light sources and make operation more convenient and simple.
