Abstract
Description
Technical Field
[0001] The utility model relates to a light reaction device, in particular to a light reaction device. Background Art
[0002] Conventional photoreaction equipment uses a heating wire and refrigeration compressor built into a circulating bath (TCU) for temperature control. The reactors need to be immersed in circulating fluid. The wavelength of the light source commonly used in photoreactions has poor permeability to liquids. Equipment using circulating fluid for temperature control may cause some experiments to fail. The biggest problem with this temperature control method is that the circulating fluid will evaporate and become contaminated after long-term use. The circulating fluid will also contaminate the instruments and equipment on the operating table, causing problems for operators. Occasional leakage will also make the floor slippery and prone to safety accidents. In addition, since the specific heat capacity of the liquid is much greater than that of the air, the heating and cooling rate of the circulating bath is slow. For small and pilot experiments, the preparation period is longer. Since a separate circulating bath needs to be configured, the equipment will be large in size, with many cables and pipes, making installation and transportation inconvenient. Utility Model Content
[0003] The technical problem to be solved by the present invention is that the existing circulating liquid temperature control equipment will cause some experiments to fail. The biggest problem of this temperature control method is that the circulating liquid will evaporate and be contaminated after long-term use. The circulating liquid will also contaminate the instruments and equipment on the operating table, causing dirt problems for the operators. Occasional leakage will also cause the ground to be slippery, which is prone to safety accidents. The present invention provides a light reaction device, which replaces the existing circulating liquid temperature control equipment with temperature control through air temperature, uses air as a cold source, and uses a light emitter as a heat source. The air temperature inside the reaction box is detected in real time to control the exhaust fan and the light emitter to adjust the reaction temperature in the reaction box. This method can effectively solve the problem of circulating liquid oil contamination, and uses the light emitter for direct irradiation to effectively solve the problem of light source transmittance. The structure is simple and easy to use, and effectively solves the problems of large equipment size, heavy weight, and long experimental preparation cycle, so as to solve the defects caused by the existing technology.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0005] In a first aspect, a photoreaction device comprises a reaction box, a movable plate and a light emitter inserted into the reaction box being mounted on one side of the reaction box, a reaction plate being mounted on a side of the movable plate facing the light emitter, and a reaction chamber being provided inside the reaction box to accommodate the movable plate and the reaction plate;
[0006] an exhaust fan installed inside the reaction box;
[0007] A temperature detector installed on the reaction box to detect the temperature in real time, obtain temperature data and transmit it to the controller;
[0008] The controller is installed on the reaction box, and the controller controls the light emitter and the exhaust fan respectively;
[0009] The temperature detector detects the real-time temperature inside and outside the reaction box and transmits it to the controller. The controller compares the real-time temperature with the preset temperature to control the light emitter and the exhaust fan to adjust the temperature inside the reaction box. The external air is used as a cold source and the light emitter is used as a heat source. The light source will generate a large amount of heat energy.
[0010] The above-mentioned photoreaction device, wherein a highly transparent quartz plate is installed between the reaction plate and the light emitter, and the highly transparent quartz plate serves as a barrier. On the basis of ensuring the high transmittance of the light source, the temperature stability in the reaction box is ensured as much as possible. The light source is directly irradiated onto the reaction plate through the highly transparent quartz plate, without circulating liquid as an intermediate medium, thereby greatly improving the utilization rate of the light source and reducing the reaction time.
[0011] In the above-mentioned light reaction device, the light emitter is an LED lamp.
[0012] The above-mentioned photoreaction device, wherein the exhaust fan is installed at the top and bottom ends of the reaction box, and the reaction box is provided with an air duct opening matching the exhaust fan. The reasonably set air duct opening controls the speed and start and stop of the exhaust fan according to the parameters of the set temperature and the actual temperature to change the air volume of the entire air duct opening, thereby realizing temperature regulation inside the reaction box.
[0013] In the above-mentioned photoreaction device, three exhaust fans are respectively provided at the top and bottom of the reaction box.
[0014] In the above-mentioned photoreaction device, the temperature detector is installed on the inner wall of the reaction box to detect the temperature inside the reaction box.
[0015] In the above-mentioned photoreaction device, movable wheels are installed on the bottom of the reaction box.
[0016] In a second aspect, different from the first aspect, this solution provides a photoreaction device, wherein the temperature detector is installed on the outer wall of the reaction box to detect the temperature inside the reaction box.
[0017] In a third aspect, different from the first aspect, this solution provides a photoreaction device, wherein the temperature detector is installed on the inner wall and the outer wall of the reaction box to detect the temperature inside the reaction box.
[0018] When using a photoreaction device of the present invention, after the photoreaction device is turned on, a target temperature value is set by the controller. If the actual temperature monitored during the experiment is higher than the set temperature, the reaction box needs to be cooled, and the exhaust fan is controlled to start, and the external room temperature air flows through the air duct opening and the interior of the reaction box to cool the entire reaction chamber. When the temperature drops to the set temperature, the fan is stopped.
[0019] After turning on the light reaction device, the target temperature value is set by the controller. If the actual temperature is monitored to be lower than the set temperature during the experiment, the temperature inside the reaction box needs to be increased, and the exhaust fan is not started. The controller turns on the light emitter for irradiation, so that the heat generated heats the reaction chamber. After monitoring that the actual temperature rises to higher than the set temperature, the exhaust fan is controlled to start, and the external room temperature air is used to flow through the air duct opening and the inside of the reaction box to cool the entire reaction chamber to the set temperature, and the exhaust fan is controlled to stop.
[0020] The entire photoreaction device only relies on the exhaust fan to adjust the flow rate of room temperature air to control the temperature of the reaction chamber, getting rid of the dependence on the circulating bath, greatly reducing equipment costs, and also eliminating the risk of circulating bath fluid leakage, reducing safety risks caused by equipment. By removing the circulating fluid as an intermediate medium, the pain point of existing equipment that cannot effectively perform shortwave experiments is solved.
[0021] The light source is directly irradiated onto the reaction plate, which greatly improves the utilization rate of the light source and reduces the reaction time and the preparation period of the circulating bath before the reaction;
[0022] Compared with traditional photoreaction equipment that relies on circulating bath temperature control, this photoreaction equipment has a compact size, which greatly improves the space utilization of the fume hood. Its simple structure also reduces the learning cost of users. It has a simple structure, light weight, is easy to carry, and changes temperature quickly, making it very suitable for small and pilot tests of photoreactions.
[0023] The technical solution provided by the above-mentioned light reaction device of the utility model has the following technical effects:
[0024] The existing circulating liquid temperature control equipment is changed to control the temperature through air temperature, with air as the cold source and the light emitter as the heat source. The air temperature inside the reaction box is detected in real time to control the exhaust fan and the light emitter to adjust the reaction temperature inside the reaction box. This method can effectively solve the problem of circulating liquid oil contamination, and use the light emitter for direct irradiation to effectively solve the problem of light source transmittance. It has a simple structure and is easy to use, effectively solving problems such as large equipment size, heavy weight, and long experimental preparation cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1-2As shown, the first embodiment is a photoreaction device, which includes a reaction box 100, a movable plate 200 and a light emitter 300 inserted into the reaction box 100 are installed on one side of the reaction box 100, a reaction plate 400 is installed on the side of the movable plate 200 facing the light emitter 300, and a reaction chamber for accommodating the movable plate 200 and the reaction plate 400 is provided inside the reaction box 100; an exhaust fan is installed inside the reaction box 100; a temperature detector 101 is installed on the reaction box 100 to detect the temperature in real time to obtain temperature data and transmit it to the controller 102; the controller 102 is installed on the reaction box 100, and the controller 102 controls the light emitter 300 and the exhaust fan respectively; the temperature detector 101 detects the real-time temperature inside and outside the reaction box 100 in real time and transmits the data to the controller 102, and the controller 102 compares the real-time temperature with the preset temperature to control the light emitter 300 and the exhaust fan respectively to adjust the temperature inside the reaction box 100, with the external air as the cooling source and the light emitter 300 as the heat source, and a large amount of heat energy is generated by the light source.
[0035] The above-mentioned photoreaction device is a device in which a highly transparent quartz plate is installed between the reaction plate 400 and the light emitter 300. The highly transparent quartz plate serves as a barrier. On the basis of ensuring the high transmittance of the light source, the temperature stability in the reaction box 100 is ensured as much as possible. The light source is directly irradiated onto the reaction plate 400 through the highly transparent quartz plate. There is no circulating liquid as an intermediate medium, which greatly improves the utilization rate of the light source and reduces the reaction time.
[0036] In the above-mentioned light reaction device, the light emitter 300 is an LED lamp.
[0037] The above-mentioned photoreaction device, in which exhaust fans are installed at the top and bottom ends of the reaction box 100, is provided with an air duct opening 103 matching the exhaust fan. The reasonably set air duct opening 103 controls the speed and start and stop of the exhaust fan according to the parameters of the set temperature and the actual temperature to change the air volume of the entire air duct opening 103, thereby realizing temperature regulation inside the reaction box 100.
[0038] In the above-mentioned photoreaction device, three exhaust fans are respectively provided at the top and bottom of the reaction box 100 .
[0039] In the above-mentioned photoreaction device, the temperature detector 101 is installed on the inner wall of the reaction box 100 to detect the temperature inside the reaction box 100 .
[0040] In the above-mentioned photoreaction device, a moving wheel 104 is installed at the bottom of the reaction box 100 .
[0041] When using a photoreaction device of this embodiment, after the photoreaction device is turned on, a target temperature value is set by the controller 102. If the temperature detector 101 detects that the actual temperature inside the reaction box 100 is higher than the set temperature during the experiment, the reaction box 100 needs to be cooled. The exhaust fan is controlled to start, and the room temperature air outside flows through the air duct opening 103 and the interior of the reaction box 100 to cool the entire reaction chamber. When the temperature drops to the set temperature, the fan is stopped.
[0042] After turning on the light reaction device, the target temperature value is set through the controller 102. If the temperature detector 101 detects that the actual temperature inside the reaction box 100 is lower than the set temperature during the experiment, the temperature inside the reaction box 100 needs to be increased, and the exhaust fan is not started. The controller 102 turns on the light emitter 300 for irradiation, so that the heat generated heats the reaction chamber. After detecting that the actual temperature inside the reaction box 100 rises to higher than the set temperature, the exhaust fan is controlled to start, and the external room temperature air is used to flow through the air duct port 103 and the inside of the reaction box 100 to cool the entire reaction chamber to the set temperature, and the exhaust fan is controlled to stop.
[0043] like Figure 1-3 As shown, the second embodiment is different from the first embodiment in that this solution is a photoreaction device, wherein the temperature detector 101 is installed on the outer wall of the reaction box 100 to detect the temperature outside the reaction box 100.
[0044] When using a photoreaction device of this embodiment, after the photoreaction device is turned on, a target temperature value is set by the controller 102. If the temperature detector 101 detects that the actual temperature outside the reaction box 100 is higher than the set temperature during the experiment, the reaction box 100 needs to be cooled. The exhaust fan is controlled to start, and the room temperature air outside flows through the air duct opening 103 and the interior of the reaction box 100 to cool the entire reaction chamber. When the temperature drops to the set temperature, the fan stops.
[0045] After turning on the light reaction device, the target temperature value is set through the controller 102. If the temperature detector 101 detects that the actual temperature outside the reaction box 100 is lower than the set temperature during the experiment, the temperature inside the reaction box 100 needs to be increased, and the exhaust fan is not started. The controller 102 turns on the light emitter 300 for irradiation, so that the heat generated heats the reaction chamber. After detecting that the actual temperature outside the reaction box 100 rises to higher than the set temperature, the exhaust fan is controlled to start, and the external room temperature air is used to flow through the air duct opening 103 and the inside of the reaction box 100 to cool the entire reaction chamber to the set temperature, and the exhaust fan is controlled to stop.
[0046] like Figure 1-3As shown, the third embodiment is different from the first embodiment in that this solution is a photoreaction device, wherein the temperature detector 101 is installed on the inner wall and the outer wall of the reaction box 100 to detect the temperature inside and outside the reaction box 100.
[0047] When using a photoreaction device of this embodiment, after the photoreaction device is turned on, a target temperature value is set by the controller 102. If the temperature detector 101 detects that the actual temperature inside and outside the reaction box 100 is higher than the set temperature during the experiment, the reaction box 100 needs to be cooled. The exhaust fan is controlled to start, and the room temperature air outside flows through the air duct opening 103 and the interior of the reaction box 100 to cool the entire reaction chamber. When the temperature drops to the set temperature, the fan is stopped.
[0048] After turning on the light reaction device, the target temperature value is set through the controller 102. If the temperature detector 101 detects that the actual temperature inside and outside the reaction box 100 is lower than the set temperature during the experiment, the temperature inside the reaction box 100 needs to be increased, and the exhaust fan is not started. The controller 102 turns on the light emitter 300 for irradiation, so that the heat generated heats the reaction chamber. After detecting that the actual temperature inside and outside the reaction box 100 rises to higher than the set temperature, the exhaust fan is controlled to start, and the external room temperature air is used to flow through the air duct port 103 and the inside of the reaction box 100 to cool the entire reaction chamber to the set temperature, and the exhaust fan is controlled to stop.
[0049] The entire photoreaction device relies solely on exhaust fans to regulate the flow of room-temperature air to control the temperature of the reaction chamber. This eliminates the need for a circulating bath, significantly reducing equipment costs and eliminating the risk of circulating bath fluid leakage, lowering safety risks associated with the equipment. By eliminating the circulating fluid as an intermediate medium, the device addresses the pain point of existing equipment that prevents effective shortwave experiments.
[0050] The light source directly irradiates the reaction plate 400, which greatly improves the utilization rate of the light source and reduces the reaction time and the preparation period of the circulating bath before the reaction;
[0051] Compared with traditional photoreaction equipment that relies on circulating bath temperature control, this photoreaction equipment has a compact size, which greatly improves the space utilization of the fume hood. Its simple structure also reduces the learning cost of users. It has a simple structure, light weight, is easy to carry, and changes temperature quickly, making it very suitable for small and pilot tests of photoreactions.
[0052] In summary, the utility model is a light reaction device that replaces the existing circulating liquid temperature control equipment with a temperature control device through air temperature, uses air as a cold source, and a light emitter as a heat source, and detects the air temperature inside the reaction box in real time to control the exhaust fan and the light emitter to adjust the reaction temperature inside the reaction box. This method can effectively solve the problem of circulating liquid oil contamination, and uses the light emitter for direct irradiation to effectively solve the problem of light source transmittance. It has a simple structure and is easy to use, and can effectively solve the problems of large equipment size, heavy weight, and long experimental preparation cycle.
