TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of photocatalytic experiment, and particularly relates to a photocatalytic experiment equipment for photocatalytic functional materials. BACKGROUND

[0002] Photocatalytic technology utilizes semiconductor materials to absorb light energy to generate electron-hole pairs, drives oxidation-reduction reactions, and shows broad prospects in clean energy, environmental governance, fine chemical industry and other fields. With the rapid development of nano thin film photocatalytic materials, accurate evaluation of their activity has become a research hotspot. However, the stability of photocatalytic thin films in liquid-solid-light three-phase interface is easily affected by fluid shear, bubble disturbance and edge warping, resulting in poor experimental repeatability and insufficient data reliability, and therefore, a high-stability experimental platform is urgently needed.

[0003] Existing photocatalytic experiment equipment mostly uses beakers, quartz cells or fixed clamps to simply immerse glass sheets coated with photocatalysts in reaction solutions, and mixes the solutions through magnetic stirring or bubbling. Such equipment has simple structure, but has obvious defects: the adhesion strength of the thin film and the substrate lacks a pre-checking link, and the thin film is prone to fall off due to poor adhesion during the experiment; the shear force and vortex generated by vigorous stirring directly impact the edge of the thin film, inducing edge warping and cracking; the clamping pressure is often achieved by rigid point contact, which causes local stress concentration and leads to micro-cracking of the thin film; in addition, the concentration gradient of the reaction solution is difficult to eliminate, further amplifying the risk of falling off, and the experimental results have high dispersion, making it difficult to obtain intrinsic activity data of the material.

[0004] Therefore, how to firmly fix the photocatalytic thin film and uniformly mix the reaction solution without introducing additional disturbance has become a core technical problem to be solved for current photocatalytic functional material experiment equipment. SUMMARY

The outer wall snap-fit ​​post 225, the pressing component 23 includes a U-shaped support frame 231 disposed at the bottom of the inner wall of the catalytic reaction box 20, a first ring 232 disposed at the top of the U-shaped support frame 231, a second ring 233 disposed on the outer ring of the first ring 232, an elastic sheet 234 whose inner ring is connected to the inner ring of the first ring 232 and whose outer ring is connected to the outer edge of the second ring 233, and a gas source pipe 235 with one end connected to the first ring 232, and also includes two fitting drive components 24 symmetrically disposed on both sides of the inner wall of the catalytic reaction box 20. The bonding drive component 24 includes a mounting box 241 disposed inside the catalytic reaction box 20 and connected at one end to the catalytic reaction box 20, and a drive cylinder 242 disposed inside the mounting box 241. The actuating end of the drive cylinder 242 passes through the mounting box 241 and is connected to the moving frame 21. The bottom of the inner wall of the experimental chamber 11 is rotatably connected to the base turntable 12. A light source 13 is provided at the center of the top of the base turntable 12. Multiple catalytic reaction boxes 20 are disposed on the base turntable 12 and are arranged in a ring array with the light source 13 as the center point.

[0022] It should be noted that in this embodiment, when the photocatalytic functional material is used to conduct a photocatalytic experiment, the first step is to prepare the sample. During sample preparation, a photocatalytic thin film is loaded onto a carrier sheet using a spin coating process. After loading is completed, a photocatalytic thin film experimental sample is formed. The second step requires sample testing. The carrier sheet loaded with the photocatalytic film is placed on the positioning carrier component 22. After loading, the photocatalytic film adhesion detection component 34 at the actuator end of the adjustment component 32 is activated to test the adhesion strength of the photocatalytic film on the carrier sheet. After the photocatalytic film adhesion detection component 34 adheres the photocatalytic film, the imaging component 33 takes a picture of the photocatalytic film to obtain the photocatalytic film image information and transmits the photocatalytic film image information to the controller. The controller receives the image information and, after analysis, determines whether the adhesion strength of the photocatalytic film is qualified. A qualified photocatalytic film should be without defects. An unqualified photocatalytic film is damaged. At this time, the controller triggers the adjustment component 32 to remove the carrier sheet corresponding to the unqualified photocatalytic film from the positioning carrier component 22 so that the experimenter can replace it, until the adhesion strength of the photocatalytic film on all carrier sheets is qualified. The third step requires pressing the edge of the photocatalytic film. This step can prevent the photocatalytic film from curling up or even peeling off the support sheet in the reaction solution. During pressing, the controller receives the image information of the pressing component 23 and the positioning support component 22 captured by the imaging component 33. After analysis, it triggers the toggle adjustment component 32 to adjust the position of the support sheet on the positioning support component 22 so that the edge of the photocatalytic film is aligned with the pressing component 23. After alignment, the drive cylinder 242 pushes the moving frame 21 until the support sheet contacts the pressing component 23. Finally, the pressing component 23 squeezes and fixes the edge of the photocatalytic film. The fourth step requires a photocatalytic reaction. The reaction liquid supply system feeds the reaction liquid into the catalytic reaction box 20 through the delivery pipe until the reaction liquid submerges the photocatalytic film. The light source 13 is turned on, and the photocatalytic reaction is started. During the reaction, the homogenizing device 40 can uniformly stir the reaction liquid to prevent uneven concentration of the reaction liquid. The homogenizing device 40 can avoid liquid fluctuations from damaging the photocatalytic film during the homogenization process of the reaction liquid. The fifth step is sampling and testing. The test personnel can take samples of the reaction solution from the catalytic reaction box 20 at regular intervals and in quantitative amounts. By analyzing the data of the reaction solution, the performance of the photocatalytic functional material can be understood. Furthermore, when the positioning support component 22 is working, the photocatalytic thin film support sheet can be directly inserted into the support frame 221. The adjusting component 32 can move the support frame 221 horizontally via the locking post 225 to adjust the horizontal position of the photocatalytic thin film support sheet. The adjusting component 32 can also move the pad 223 up and down via the locking post 225 to adjust the height of the photocatalytic thin film support sheet. After the actuating end of the adjusting component 32 separates from the locking post 225, the pad 223 is fixed by the magnetic friction between the magnetic block 224 and the iron sheet 222. Furthermore, when the edge pressing component 23 is working, the gas source pipe 235 can be connected to the gas source system. When the gas source system is turned on, the pressurized gas enters between the first ring 232, the second ring 233 and the elastic sheet 234 through the gas source pipe 235. The elastic sheet 234 expands to press and fix the edge of the photocatalytic film.

The position adjustment device 30 includes a self-driving plate 31 rotatably connected to the top of the inner wall of the experimental chamber 11, and a toggle adjustment component 32 and a shooting component 33 provided at the bottom of the self-driving plate 31. The toggle adjustment component 32 is used to adjust the positioning support component 22 so that the pressing edge component 23 is aligned with the edge of the photocatalytic film. The shooting component 33 is located on the side of the pressing edge component 23 away from the positioning support component 22. The toggle adjustment component 32 includes two first linear modules 321 symmetrically provided at the bottom of the self-driving plate 31, a second linear module 322 connected at both ends to the execution ends of the two first linear modules 321, a telescopic cylinder 323 provided at the execution end of the second linear module 322, and a U-shaped component provided at the execution end of the telescopic cylinder 323. The U-shaped clip holder 324 also includes a photocatalytic film adhesion detection component 34 disposed at the actuating end of the telescopic cylinder 323.

[0024] It should be noted that, in this embodiment, when the position adjustment device 30 is working, the motor actuator drives the self-driving plate 31 to rotate until the toggle adjustment component 32 and the imaging component 33 move to the top of one of the catalytic reaction boxes 20 to be processed. When the toggle adjustment component 32 is working, the actuator of the first linear module 321 drives the second linear module 322 to move. The actuator of the second linear module 322 drives the telescopic cylinder 323 to move. The actuator of the telescopic cylinder 323 drives the U-shaped clip bracket 324 and the photocatalytic film adhesion detection component 34 to rise and fall. The U-shaped clip bracket 324 can clip the clip post 225. Furthermore, when the shooting component 33 is working, the actuator of the third linear module 331 drives the power cylinder 332 to move, the actuator of the power cylinder 332 drives the camera 333 to rise and fall, and the camera 333 takes pictures. The camera 333 can take pictures through the first ring 232 to facilitate understanding of the offset between the photocatalytic film on the carrier sheet and the first ring 232. Furthermore, when the photocatalytic film adhesion detection component 34 is working, the tape roll is placed in the tape box 342 without the micro motor 344 installed on the top and is sleeved on the outer wall of the rotating shaft 343. The end of the tape roll passes through the tape box 342 without the micro motor 344 installed on the top, passes through the support plate 345 and then passes into another tape box 342 and is fixed to the rotating shaft 343 in the other tape box 342. During testing, the adjusting component 32 moves the photocatalytic film adhesion detection component 34 until the tape adheres to the photocatalytic film. After a unit of time, the tape separates to complete the test. At this time, the micro motor 344 drives the rotating shaft 343 to rotate, and the tape at the corresponding position of the support plate 345 is renewed, so that the next test can be performed.

[0025] Please refer to the appendix for details.

The homogenizing device 40 includes a homogenizing box 41 provided at the bottom of the inner wall of the catalytic reaction box 20, a liquid inlet 42 provided at the top of the homogenizing box 41 and located on the side of the positioning support member 22 away from the pressing member 23, a drive motor 43 provided at the bottom of the catalytic reaction box 20 and whose execution end passes through the catalytic reaction box 20 and the homogenizing box 41 and extends into the homogenizing box 41, and a stirring device provided at the execution end of the drive motor 43. Rod 44; the bottom of the U-shaped support frame 231 is fixed to the top of the catalytic reaction box 20, the bottom of the movable frame 21 is slidably connected to the top of the catalytic reaction box 20, and also includes a liquid guiding component 45, the liquid guiding component 45 including a liquid delivery pump 451 disposed on the outer wall of the catalytic reaction box 20, and a U-shaped spray pipe 452 disposed on the U-shaped support frame 231; the liquid inlet end of the liquid delivery pump 451 is connected to the mixing box 41 through a pipe, and the liquid outlet end of the liquid delivery pump 451 is connected to multiple U-shaped spray pipes 452 through a pipe.

[0026] It should be noted that, in this embodiment, when the homogenizing device 40 is working, the reaction liquid in the catalytic reaction box 20 can enter the homogenizing box 41 through the liquid inlet 42. The drive motor 43 can drive the stirring rod 44 to rotate. The stirring rod 44 stirs the reaction liquid in the homogenizing box 41 evenly. At the same time, due to the influence of the homogenizing box 41, it can effectively prevent the swirling flow from directly impacting the photocatalytic film. Furthermore, after the liquid transfer pump 451 is turned on, the reaction liquid in the mixing box 41 can be sprayed out through the pipeline, the liquid transfer pump 451 and the pipeline, and then through the U-shaped spray pipe 452. At this time, the photocatalytic film can continuously perform photocatalysis on the uniform reaction liquid.

[0027] The working principle of this invention is as follows: When conducting photocatalytic experiments with photocatalytic functional materials, the first step is to prepare the sample. During sample preparation, a photocatalytic film is loaded onto a carrier sheet using a spin coating process. After loading, the photocatalytic film experimental sample is formed. The second step requires sample testing. The carrier sheet loaded with the photocatalytic film is placed on the positioning carrier component 22. After loading, the photocatalytic film adhesion detection component 34 at the actuator end of the adjustment component 32 is activated to test the adhesion strength of the photocatalytic film on the carrier sheet. After the photocatalytic film adhesion detection component 34 adheres the photocatalytic film, the imaging component 33 takes a picture of the photocatalytic film to obtain the photocatalytic film image information and transmits the photocatalytic film image information to the controller. The controller receives the image information and, after analysis, determines whether the adhesion strength of the photocatalytic film is qualified. A qualified photocatalytic film should be without defects. An unqualified photocatalytic film is damaged. At this time, the controller triggers the adjustment component 32 to remove the carrier sheet corresponding to the unqualified photocatalytic film from the positioning carrier component 22 so that the experimenter can replace it, until the adhesion strength of the photocatalytic film on all carrier sheets is qualified. The third step requires pressing the edge of the photocatalytic film. This step can prevent the photocatalytic film from curling up or even peeling off the support sheet in the reaction solution. During pressing, the controller receives the image information of the pressing component 23 and the positioning support component 22 captured by the imaging component 33. After analysis, it triggers the toggle adjustment component 32 to adjust the position of the support sheet on the positioning support component 22 so that the edge of the photocatalytic film is aligned with the pressing component 23. After alignment, the drive cylinder 242 pushes the moving frame 21 until the support sheet contacts the pressing component 23. Finally, the pressing component 23 squeezes and fixes the edge of the photocatalytic film. The fourth step requires a photocatalytic reaction. The reaction liquid supply system feeds the reaction liquid into the catalytic reaction box 20 through the delivery pipe until the reaction liquid submerges the photocatalytic film. The light source 13 is turned on, and the photocatalytic reaction is started. During the reaction, the homogenizing device 40 can uniformly stir the reaction liquid to prevent uneven concentration of the reaction liquid. The homogenizing device 40 can avoid liquid fluctuations from damaging the photocatalytic film during the homogenization process of the reaction liquid. The fifth step is sampling and testing. The test personnel can take samples of the reaction solution from the catalytic reaction box 20 at regular intervals and in quantitative amounts. By analyzing the data of the reaction solution, the performance of the photocatalytic functional material can be understood. When the positioning support component 22 is working, the photocatalytic thin film support sheet can be directly inserted into the support frame 221. The adjusting component 32 can move the support frame 221 horizontally via the locking post 225 to adjust the horizontal position of the photocatalytic thin film support sheet. The adjusting component 32 can also move the pad 223 up and down via the locking post 225 to adjust the height of the photocatalytic thin film support sheet. After the actuating end of the adjusting component 32 separates from the locking post 225, the pad 223 is fixed by the magnetic friction between the magnetic block 224 and the iron sheet 222. When the edge pressing component 23 is working, the gas source pipe 235 can be connected to the gas source system. When the gas source system is turned on, the pressurized gas enters between the first ring 232, the second ring 233 and the elastic sheet 234 through the gas source pipe 235. The elastic sheet 234 expands to press and fix the edge of the photocatalytic film. When the position adjustment device 30 is working, the motor actuator drives the self-driving plate 31 to rotate until the toggle adjustment component 32 and the shooting component 33 move to the top of one of the catalytic reaction boxes 20 to be processed. When the toggle adjustment component 32 is working, the actuator of the first linear module 321 drives the second linear module 322 to move. The actuator of the second linear module 322 drives the telescopic cylinder 323 to move. The actuator of the telescopic cylinder 323 drives the U-shaped clip 324 and the photocatalytic film adhesion detection component 34 to rise and fall. The U-shaped clip 324 can clip the clip post 225. When the camera component 33 is working, the actuator of the third linear module 331 drives the power cylinder 332 to move, and the actuator of the power cylinder 332 drives the camera 333 to rise and fall. The camera 333 takes pictures, and the camera 333 can take pictures through the first ring 232 to facilitate understanding of the offset between the photocatalytic film on the carrier sheet and the first ring 232. When the photocatalytic film adhesion detection component 34 is working, the tape roll is placed in the tape box 342 without the micro motor 344 installed on the top and is sleeved on the outer wall of the rotating shaft 343. The end of the tape roll passes through the tape box 342 without the micro motor 344 installed on the top, passes through the support plate 345 and then passes into another tape box 342 and is fixed to the rotating shaft 343 in the other tape box 342. During testing, the adjustment component 32 is moved to move the photocatalytic film adhesion detection component 34 until the tape adheres to the photocatalytic film. After a unit of time, the tape separates to complete the test. At this time, the micro motor 344 drives the rotating shaft 343 to rotate, and the tape at the corresponding position of the support plate 345 is renewed, so that the next test can be carried out. When the homogenizing device 40 is working, the reaction liquid in the catalytic reaction box 20 can enter the homogenizing box 41 through the liquid inlet 42. The drive motor 43 can drive the stirring rod 44 to rotate. The stirring rod 44 stirs the reaction liquid in the homogenizing box 41 evenly. At the same time, due to the influence of the homogenizing box 41, it can effectively prevent the swirling flow from directly impacting the photocatalytic film. After the liquid transfer pump 451 is turned on, the reaction liquid in the homogenizing box 41 can be sprayed out through the pipeline, the liquid transfer pump 451 and the pipeline, and then through the U-shaped spray pipe 452. At this time, the photocatalytic film can continuously perform photocatalysis on the homogenized reaction liquid.
