[0043] Example 1

[0044] This embodiment provides a chemical agent screening device, which can reduce the temperatures of the lamp board and the light source, reduce the interference of the lamp board temperature and the light source temperature on the experimental results, improve the accuracy and reliability of the experimental results, extend the service life of the light source, and save costs.

[0045] As Figures 1 - 7 shown, the chemical agent screening device mainly includes a mounting plate 100 and a lamp board 200. Among them, the mounting plate 100 is provided with a plurality of mounting grooves 110, and the mounting grooves 110 are configured to place glass bottles 10 containing chemical agents. The lamp board 200 is connected to the mounting plate 100, and the lamp board 200 is located below the mounting plate 100. A plurality of light sources 210 are provided on the lamp board 200. The light sources 210 are located directly below the mounting grooves 110, and the light sources 210 correspond to the mounting grooves 110 one by one; a first liquid inlet 220 and a first liquid outlet 230 are provided on the lamp board 200, and the height of the first liquid inlet 220 is lower than the height of the first liquid outlet 230; a first flow channel 240 is provided inside the lamp board 200, and the first liquid inlet 220, the first flow channel 240, and the first liquid outlet 230 are sequentially connected in series, and the refrigerant can flow into the first flow channel 240 through the first liquid inlet 220 and then flow out through the first liquid outlet 230.

[0046] Based on the above design, the glass bottle 10 in this embodiment can be made of quartz glass or borosilicate glass, which is beneficial to achieving higher light transmittance and facilitating the full reaction of the chemical agent in the glass bottle 10. The lamp board 200 and the mounting plate 100 in this embodiment can be detachably connected by countersunk screws, which is beneficial to the disassembly and maintenance of the lamp board 200 and the mounting plate 100 in the later stage. The light source 210 in this embodiment can be set as common lamp beads on the market, and both the light source 210 and the mounting grooves 110 can be set in a rectangular array, so that the distance between adjacent two glass bottles 10 can be kept consistent, reducing the variable factors in the experiment and improving the accuracy of the experimental data.

[0047] The refrigerant in this embodiment can be set as cooling water, ethylene glycol, ethanol, heat-conducting oil, etc. Both the first liquid inlet 220 and the first liquid outlet 230 are connected to an external refrigerant source, and the refrigerant source can drive the refrigerant from the first liquid inlet 220 into the first flow channel 240 and then flow back to the refrigerant source through the first liquid outlet 230. The refrigerant source is a conventional component in the art and can be set as a common temperature control integrated machine on the market, etc. The height of the first liquid inlet 220 is lower than the height of the first liquid outlet 230, so that the refrigerant in the first flow channel 240 can fill the first flow channel 240 as much as possible, increasing the volume of the refrigerant in the first flow channel 240, thereby improving the cooling effect on the lamp board 200 and the light source 210. Figure 7The direction of the arrow in the figure is the flow direction of the refrigerant in the first flow channel 240.

[0048] Compared with the prior art, in this embodiment, through the settings of the mounting plate 100 and the lamp board 200, and the lamp board 200 is provided with a first flow channel 240, a first liquid inlet 220 and a first liquid outlet 230, so that the refrigerant flows into the first flow channel 240 and cools the lamp board 200 and the light source 210 on the lamp board 200, reducing the influence of the temperature rise of the light source 210 on the experimental results, improving the accuracy and reliability of the experimental results, prolonging the service life of the light source 210, and saving costs.

[0049] Optionally, both the lamp board 200 and the mounting plate 100 in this embodiment are made of metal materials. For example, the lamp board 200 can be made of aluminum alloy material, and the mounting plate 100 is made of copper alloy material. Of course, the operator can also use other materials to process and make the lamp board 200 and the mounting plate 100, and this embodiment will not elaborate too much on this.

[0050] As Figures 5 - 7 shown, in this embodiment, a plurality of first flow channels 240 are provided. For example, the first flow channels 240 can be set to 4, 5, 6, 7, 8, etc. And the plurality of first flow channels 240 are connected in series in sequence; a first baffle 250 is provided between adjacent two first flow channels 240, and the plurality of first baffles 250 are centrally symmetrically arranged about the central position of the lamp board 200. In this way, through the setting of the first baffle 250, the flow area of the refrigerant can be increased, the flow path of the refrigerant can be extended, so that the refrigerant can be filled in the first flow channel 240 as much as possible, and the heat dissipation and cooling effect of the refrigerant on the lamp board 200 can be improved. Further, the length of the first baffle 250 is less than the length of each first flow channel 240, so that the refrigerant can flow smoothly from the previous first flow channel 240 to the next first flow channel 240, avoiding the phenomenon of flow dead zones.

[0051] As Figure 7 shown, a plurality of first protrusions 2401 are provided in the first flow channel 240 in this embodiment. The first protrusions 2401 are configured to disturb the flow of the refrigerant, reduce the flow rate of the refrigerant, increase the contact area between the refrigerant and the inner wall of the first flow channel 240, extend the flow time of the refrigerant in the first flow channel 240, and improve the cooling effect on the lamp board 200 and the light source 210.

[0052] Exemplarily, the cross-section of the first protrusion 2401 can be set to a circular shape, a notch shape, a triangular shape, an irregular shape, etc. And the operator can set the arrangement mode of the first protrusions 2401 in a certain arrangement order. For example, one first protrusion 2401 can be set in the odd rows, and two first protrusions 2401 can be set in the even rows for arrangement, so as to improve the flow and heat transfer effect of the refrigerant, and make the temperature of the refrigerant in the first flow channel 240 as consistent as possible. Other arrangement modes of the first protrusions 2401 also fall within the protection scope of this embodiment, and will not be elaborated here.

[0053] As Figures 5 - 6 shown, in this embodiment, a groove 260 is provided on the lamp board 200. The lamp board 200 further includes a copper substrate 270. The light source 210 is arranged on the copper substrate 270, and the copper substrate 270 is bonded in the groove 260 through heat-conducting silicone grease, so as to improve the heat transfer effect between the lamp board 200 and the light source 210. Specifically, the heat of the light source 210 can be transferred to the lamp board 200 through the copper substrate 270, and then the lamp board 200 exchanges heat with the refrigerant, and the refrigerant takes away the heat of the lamp board 200 to achieve the cooling effect on the lamp board 200.

[0054] Optionally, multiple columns of grooves 260 are provided in this embodiment, and multiple light sources 210 are arranged in each column of grooves 260, and one copper substrate 270 is arranged in each column of grooves 260. That is to say, multiple light sources 210 are arranged on one copper substrate 270. For example, the number can be set to 3, 4, 5, etc.

[0055] Furthermore, the light intensity and wavelength of the light sources 210 in adjacent two columns of grooves 260 are independent of each other. That is to say, the wavelengths of the light sources 210 in each column can be the same or different, and the light intensities of the light sources 210 in each column can be the same or different, so that the chemical agent screening device can be used to experiment on the influence of variables of different wavelengths on chemical agents and experiment on the influence of variables of different light intensities on chemical agents, improving the compatibility and flexible applicability of the chemical agent screening device.

[0056] In addition, the chemical agent screening device in this embodiment can also experiment on the types of photosensitizers and the material ratios of different concentrations of chemical agents, and only need to control the remaining variables unchanged, and experiment with the type of photosensitizer as a variable, or experiment with the material ratios of different concentrations of chemical agents as a variable.

[0057] Optionally, the light source 210 and the installation groove 110 in this embodiment are both arranged in a rectangular array.

[0058] As Figures 5 - 6As shown, in this embodiment, a first step portion 280 is provided at the top edge of the groove 260, and quartz glass or borosilicate glass is installed on the first step portion 280, so as to play a certain protective role for the light source 210, avoid damage to the light source 210 by foreign objects from the outside, extend the service life, and at the same time ensure high light transmittance.

[0059] Furthermore, a second step portion 290 is provided at the top edge of the first step portion 280 in this embodiment, and a limiting portion (not shown in the figure) is provided at the bottom of the mounting plate 100. The limiting portion is installed on the second step portion 290, so that the mounting plate 100 can be stably adapted to the lamp board 200, avoiding the phenomenon that the mounting plate 100 shakes or is unstable relative to the lamp board 200, improving the reliability and accuracy of the experiment, and reducing the interference of adverse factors. In addition, through the cooperation and installation of the second step portion 290 and the limiting portion at the bottom of the mounting plate 100, it is also possible to effectively avoid the interference effect of the mutual transmission of light sources between different wavelengths on the experimental results, so as to ensure the singularity of screening light sources of different wavelengths and improve the accuracy and reliability of experimental data.

[0060] As Figure 3 and Figure 8 shown, in this embodiment, the mounting plate 100 is provided with a second liquid inlet 120 and a second liquid outlet 130. The height of the second liquid inlet 120 is lower than the height of the second liquid outlet 130; a second flow channel 140 is provided inside the mounting plate 100, and the mounting groove 110 penetrates the second flow channel 140. The second liquid inlet 120, the second flow channel 140 and the second liquid outlet 130 are connected in series in sequence, and the heat exchange medium can flow into the second flow channel 140 through the second liquid inlet 120 and then flow out through the second liquid outlet 130.

[0061] Specifically, the heat exchange medium in this embodiment can be set as a refrigerant or a heat medium. When the heat exchange medium is a refrigerant, both the second liquid inlet 120 and the second liquid outlet 130 are connected to the external refrigerant source. The refrigerant source can drive the refrigerant from the second liquid inlet 120 into the second flow channel 140 and then flow back to the refrigerant source through the second liquid outlet 130. The refrigerant source is a conventional component in the art and can be set as a common temperature control integrated machine with refrigerant on the market, etc. The height of the second liquid inlet 120 is lower than the height of the second liquid outlet 130, so that the refrigerant in the second flow channel 140 can fill the second flow channel 140 as much as possible, increasing the volume of the refrigerant in the second flow channel 140, thereby improving the cooling effect on the mounting plate 100 and keeping the temperature of the chemical agent in the glass bottle 10 within the range required for the reaction.

[0062] When the heat exchange medium is heat medium, both the second liquid inlet 120 and the second liquid outlet 130 are connected to the external heat medium source. The heat medium source can drive the heat medium from the second liquid inlet 120 into the second flow channel 140, and then flow back to the heat medium source through the second liquid outlet 130. The heat medium source is a conventional component in the art and can be set as a common temperature control integrated machine with heat medium on the market, etc. At this time, the heat medium can conduct heat transfer to the mounting plate 100, causing the temperature of the mounting plate 100 to rise, so as to meet the requirement of the chemical agent in the glass bottle 10 for a higher heating temperature, and improve the compatibility and flexible applicability of the chemical agent screening device. It should be noted that when the heat medium flows in the second flow channel 140, the operator usually needs to close the refrigerant flow in the lamp panel 200, that is, there is no need for the refrigerant to flow in the first flow channel 240 of the lamp panel 200 at this time, so as to improve the heating effect of the heat medium in the mounting plate 100 on the glass bottle 10, ensure that the reaction temperature of the chemical agent in the glass bottle 10 remains within a reasonable range, and at the same time, it can also achieve the effect of energy saving. Figure 8 The arrow direction in it is the flow direction of the heat exchange medium in the second flow channel 140.

[0063] It should be noted that the first flow channel 240 and the second flow channel 140 in this embodiment are independent of each other.

[0064] Optionally, the heat medium can be set as hot water, heat-conducting oil, etc.

[0065] Such as Figure 8 shown, in this embodiment, the second flow channels 140 are provided in multiple numbers, and the multiple second flow channels 140 are connected in series in sequence; a second baffle 150 is provided between two adjacent second flow channels 140, and the length of the second baffle 150 is less than the length of each second flow channel 140. And the multiple second baffles 150 are symmetrically arranged about the central position of the mounting plate 100. In this way, through the setting of the second baffle 150, the flow area of the heat exchange medium can be increased, the flow path of the heat exchange medium can be extended, so that the heat exchange medium can be filled in the second flow channel 140 as much as possible, and the heat transfer efficiency of the heat exchange medium to the mounting plate 100 can be improved. Further, the length of the second baffle 150 is less than the length of each second flow channel 140, so that the heat exchange medium can flow smoothly from the previous second flow channel 140 to the next second flow channel 140, avoiding the phenomenon of flow dead zones.

[0066] Such as Figure 8 shown, in this embodiment, both the second baffle 150 and the inner wall of the mounting plate 100 are provided with second protrusions 160, and the second protrusions 160 are configured to disturb the heat exchange medium, thereby reducing the flow rate of the heat exchange medium, increasing the contact area between the heat exchange medium and the inner wall of the second flow channel 140 and the wall of the mounting groove 110, extending the time of the heat exchange medium in the second flow channel 140, and improving the heat transfer effect on the mounting plate 100 and the glass bottle 10.

[0067] As Figure 3 shown, in this embodiment, the first liquid inlet 220 and the first liquid outlet 230 are both located on one side surface of the lamp board 200, and the second liquid inlet 120 and the second liquid outlet 130 are both located on one side surface of the mounting board 100. Moreover, the first liquid inlet 220, the first liquid outlet 230, the second liquid inlet 120, and the second liquid outlet 130 are all located on the same side, which can facilitate the operator to install the external pipeline, enabling the two temperature control integrated machines to be respectively connected to the mounting board 100 and the lamp board 200, improving the assembly efficiency, saving time and effort. At the same time, it can also reduce the phenomenon of pipeline entanglement.

[0068] As Figure 8 shown, in this embodiment, a support portion 1101 is provided at the bottom of the installation groove 110. The support portion 1101 is coaxially arranged with the installation groove 110, and the support portion 1101 is used to support the glass bottle 10, which can avoid the phenomenon of the glass bottle 10 falling, improving stability and reliability.

[0069] Preferably, the support portion 1101 is arranged in an annular structure, making the force on the glass bottle 10 more stable. The heights of multiple support portions 1101 are the same, enabling the heights of multiple glass bottles 10 to be consistent, reducing the impact on the experimental results, and improving the accuracy and reliability of experimental data.

[0070] As Figures 1 - 3 shown, in this embodiment, the chemical agent screening device further includes a vibration source 300. The vibration source 300 is connected to the lamp board 200 and is located below the lamp board 200. By setting the vibration source 300, the mixing of the chemical agent in the glass bottle 10 can be accelerated, the reaction rate of the chemical agent can be increased, the reaction can be made more sufficient, and time can be saved.

[0071] Optionally, the vibration source 300 in this embodiment includes a shaker-type vibration source (i.e., it can vibrate up, down, left, and right), a magnetic stirring-type vibration source, or a microwave ultrasonic vibration source. Of course, the operator can also adopt other types of vibration sources 300 according to actual needs, and this embodiment does not limit this.

[0072] Preferably, the vibration source 300 in this embodiment selects a magnetic stirring-type vibration source, and a shuttle-shaped magnetic stirrer is placed in the glass bottle 10, which can improve the stirring rate of the chemical agent in the glass bottle 10, making the reaction of the chemical agent more sufficient and saving time costs.

[0073] In this embodiment, the vibration source 300 may also be provided with a switch knob 310 for controlling the start of the vibration source 300, a vibration intensity adjustment knob 320 for adjusting the vibration frequency of the vibration source 300; and a wavelength knob 330 for controlling the light wavelength of the light source 210 on the lamp board 200, and a light intensity knob 340 for controlling the light intensity of the light source 210 on the lamp board 200. The wavelength knob 330 and the light intensity knob 340 may be provided in multiple numbers, and each wavelength knob 330 and each light intensity knob 340 correspond to the light source 210 in a column of grooves 260 at the same time. It should be emphasized that the working principles and specific structures of the switch knob 310, the vibration intensity adjustment knob 320, the wavelength knob 330, and the light intensity knob 340 belong to the prior art, and this embodiment will not elaborate on them specifically.

[0074] Optionally, the vibration source 300 and the lamp board 200 in this embodiment are detachably connected by bolts (not shown in the figure). On the one hand, it can improve the connection stability and reliability between the vibration source 300 and the lamp board 200, and avoid the loosening phenomenon between the lamp board 200 and the vibration source 300 during vibration. On the other hand, it can also facilitate the disassembly and replacement of the lamp board 200 in the later stage, saving time and effort and reducing costs.

[0075] As Figures 1 - 3 shown, in this embodiment, the chemical agent screening device further includes a fan assembly 400 and a hinge (not shown in the figure). The fan assembly 400 is disposed on the mounting plate 100 through the hinge in an openable and closable manner. By providing the fan assembly 400, the heat exchange effect can be enhanced, the heat dissipation efficiency of the chemical agent screening device can be improved, and heat concentration can be avoided. It should be noted that when the heat exchange medium flowing in the mounting plate 100 is a heat medium, the operator can not start the fan assembly 400 to ensure that the reaction temperature of the chemical agent is within a reasonable range.

[0076] Furthermore, the fan assembly 400 in this embodiment includes a cover body 410 and fan blades 430. The fan blades 430 are disposed inside the cover body 410, and the cover body 410 is connected to the mounting plate 100 through a hinge; a relief groove 420 is provided on the side of the cover body 410 facing the mounting plate 100, and the end face of the fan blade 430 close to the mounting plate 100 is lower than the bottom wall of the relief groove 420. By providing the relief groove 420, it can be avoided that the fan blades 430 damage the glass bottle 10 during rotation, and the safety performance is improved. At the same time, the cover body 410 can play a certain protective role for the glass bottle 10, avoiding damage to the glass bottle 10 by foreign objects from the outside or contamination of the glass bottle 10 by external dust, and improving the safety and the accuracy of experimental data.

[0077] Even further, ventilation holes 440 are opened on the cover body 410 in this embodiment, which is beneficial to the flow of gas and facilitates the dissipation of heat on the mounting plate 100.

[0078] Experimental cases:

[0079] Case 1: For a raw material SM-A, the light source wavelength, solvent, and photosensitizer were screened. As the reaction proceeded, the chemical agent gradually changed from colorless to purplish red, and the product solution was detected by liquid chromatography. It was initially found that when acetonitrile was selected as the solvent, benzophenone was selected as the photosensitizer, and the light source wavelength was selected at 310 nm, both the conversion rate and selectivity were relatively high.

[0080]

[0081]

[0082] Case 2: For a raw material SM-A, based on Case 1, the screening of material concentration, reaction temperature, and reaction time was carried out with acetonitrile as the solvent, benzophenone as the photosensitizer, and the light source wavelength at 310 nm.

[0083]

[0084]

[0085] Based on the above two groups of cases, it is not difficult to conclude that the extension of the reaction time of this reaction will produce impurity by-products, and the increase in temperature will also lead to an increase in impurities. Through comprehensive comparison, when the concentration is increased to 1.5 mol / L, the reaction temperature is reduced to 20 °C, and the reaction time is 1.5 h, the reaction effect is the best. Subsequently, the reaction time can be further optimized, and the material concentration can be appropriately increased to improve the reaction productivity.

[0086] Example 2:

[0087] This example provides a chemical agent screening device. The main difference between this chemical agent screening device and that of Example 1 is that the first liquid outlet 230 in this example is connected to the second liquid inlet 120, and both the first liquid inlet 220 and the second liquid outlet 130 are connected to the external temperature control unit, so that the first flow channel 240 and the second flow channel 140 are connected, and the refrigerant in the first flow channel 240 can flow into the second flow channel 140, achieving the cooling effect on the lamp board 200 and the mounting board 100.

[0088] Through the setting of the above structure, the connection between the lamp board 200 and the mounting board 100 can be realized. Only one temperature control unit is required to achieve the cooling effect on the lamp board 200 and the mounting board 100. The volume is miniaturized, the floor area is saved, it is convenient for installation, and the cost is saved.

[0089] It should be emphasized that only the refrigerant can flow in the first flow channel 240 and the second flow channel 140 in this example, that is, the heat exchange medium of the mounting board 100 can only be the refrigerant, so as to avoid the damage of the heat medium to the lamp board 200 and the light source 210, extend the service life, and achieve the purpose of cost saving.

[0090] The remaining structures of the chemical agent screening device in this embodiment are the same as those in the first embodiment, and will not be described in detail here.
