[0002] Solar energy, as a clean and renewable energy source, has become a crucial global issue in its development and utilization. In the field of chemistry, photochemical reactions utilize light energy to drive chemical processes, demonstrating enormous application potential in organic synthesis, environmental remediation, and new energy development. Using solar energy as an energy source for photochemical reactions can significantly reduce reaction costs and aligns with the principles of green chemistry and sustainable development. However, directly using sunlight as a light source for photochemical reactions suffers from the problem of weak sunlight intensity, leading to slow reactions or even making them difficult to proceed. Therefore, in practical applications, LED light sources, xenon lamps, and mercury lamps are commonly used to replace sunlight. However, these light sources have drawbacks, such as high equipment costs and the need for electricity. To efficiently utilize sunlight for photochemical reactions, specialized photochemical reaction devices are required.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-6 This utility model discloses a light-reacting device utilizing sunlight, comprising a base 1 and a solar reflector 2 disposed above the base 1. A rotating assembly 6 is located at the center of the base 1, and an adjusting assembly 4 is disposed between the rotating assembly 6 and the solar reflector 2. A first support rod 403 of the adjusting assembly 4 passes through the center of the solar reflector 2, and a second support rod 501 of the adjusting assembly 4 is disposed on the outer side of the solar reflector 2. A first fixing frame 503 is disposed between the first and second support rods 403 and 501. The first fixing frame 503 has a central section... There is a support ring 504. The two ends of the first fixed frame 503 are fixedly connected to the sliding rods 502 on the first support rod 403 and the second support rod 501, respectively. A second fixed frame 507 is provided above the first fixed frame 503. A motor 508 is fixed in the middle of the second fixed frame 507. The two ends of the second fixed frame 507 are connected to the sliding cylinders 506 on the sliding rods 502, respectively. A reaction vessel cover 509 is provided on the upper part of the stirring shaft 510 of the motor 508. The reaction vessel cover 509 matches the reaction vessel 3 provided on the support ring 504.

[0025] The support ring 504 has multiple adjusting rods 505 on its wall for placing the reaction vessel. In this embodiment, there are four rods, ensuring that the high-energy beam reflected from the solar reflector 2 shines unobstructed onto the bottom of the reaction vessel 3, achieving omnidirectional illumination of the bottom. The adjusting rods 505 are threadedly connected to the support ring 504, allowing the adjusting rods 505 to be screwed inwards for easy placement of the small reaction vessel. The reaction vessel cover 509 has an exhaust port 512, through which gases in the reaction vessel 3 are discharged during the reaction. The support ring 504 is a ring-shaped, bottomless, and lidless metal product with multiple adjusting rods 505 on its wall for placing the reaction vessel. The support ring 504 has a certain height, and the bottom of the reaction vessel 3 is located inside the support ring 504, thus preventing the reaction vessel 3 from tipping over. The adjusting rods 505 are used to support the reaction vessel 3. The reflective surface of the solar reflector 2 is an arc surface, which can focus sunlight onto the bottom of the reaction vessel 3. The reaction vessel 3 is made of colorless and transparent glass or quartz.

[0026] The outer sides of the two sliding rods 502 and the two sliding cylinders 506 are respectively provided with positioning pins 511, and the first support rod 403, the second support rod 501, the sliding rod 502 and the sliding cylinder 506 are provided with pin holes for adjusting the height of the first fixing frame 503 and the second fixing frame 507.

[0027] A first inclined support rod 513 is provided between the first fixed frame 503 and the sliding rod 502, and a second inclined support rod 514 is provided between the second fixed frame 507 and the sliding cylinder 506.

[0028] The adjustment component 4 includes a hollow circular connecting frame 401 located on the back of the solar reflector 2. The two ends of the bottom circumference of the connecting frame 401 are rotatably connected to the fixed rod 402. The fixed rod 402 is fixedly connected to the first support rod 403. The bottom of the first support rod 403 is connected to the top of the triangular support frame 405. The triangular support frame 405 is fixed on the rotating component 6. The first support rod 403 passes through the connecting frame 401.

[0029] The lower part of the first support rod 403 is provided with a first connecting seat 404. One end of the threaded rod 407 is rotatably connected to the rotating shaft of the first connecting seat 404 via a connecting post 406. A connecting cylinder 408 is threadedly connected to the threaded rod 407. The top of the connecting cylinder 408 is connected to a turntable 410. The turntable 410 is provided with a handle. A rotating ring 412 is fixedly connected to the upper outer wall of the connecting cylinder 408. A connecting piece 409 is rotatably connected to the outer wall of the rotating ring 412. The groove inside the connecting piece 409 is usually fitted with a rolling bearing to isolate the rotating part of the connecting cylinder 408. The torque is transmitted only in a linear push-pull motion. Connector 409 is rotatably connected to the portal frame 411 on the connecting frame 401. This rotatable connection between connector 409 and the connecting frame 411 forms a push rod mechanism, ultimately transmitting the linear motion of the connecting cylinder 408 to the connecting frame 401, causing it to rotate about the fixed rod 402. The line connecting the bottom of the connecting frame 411 to the center of the connecting frame 401 is perpendicular to the fixed rod 402, which is located on the diameter of the connecting frame 401. The threaded rod 407 is typically a T-shaped or trapezoidal screw to ensure self-locking, thus achieving the effect of converting rotational motion into linear motion.

[0030] The fixed rod 402 and the first support rod 403 form a cross shape. The bottom of the connecting frame 401 is provided with a connector with holes. The two ends of the fixed rod 402 are inserted into the holes of the connector, so that the connecting frame 401 rotates about the fixed rod 402 as an axis.

[0031] The bottom of the second support rod 501 is a triangular support frame, which is mounted on the rotating disk 601.

[0032] The rotating component 6 is typically made of high-strength cast iron or steel and includes a rotating disk 601. The center of the bottom surface of the rotating disk 601 is connected to the top of the rotating shaft through a bearing seat. The bottom of the rotating shaft is fixedly connected to the bottom surface of the base 1. A positioning bolt 602 is provided on the rotating disk 601. The positioning bolt 602 is located on the outer circumference of the rotating disk 601. A circular groove is provided on the side wall of the outer circumference of the rotating disk 601. The hollow edge of the top surface of the base is inserted into the groove. The positioning bolt 602 is inserted from the top surface of the rotating disk 601 into the threaded hole on the top surface of the base. The threaded holes are evenly distributed on the hollow edge of the top surface of the base.

[0033] The positioning bolt 602 is locked in place by the bolt holes on the rotating disk 601 and the threaded holes inside the base 1. The positioning bolt 602 is usually a high-strength hexagonal bolt, which achieves the effect of locking the position of the rotating disk 601 after adjustment, preventing it from shifting due to external forces (such as wind). The positioning bolt 602 is threadedly connected to the base 1.

[0034] This invention uses an operating handle to rotate the turntable 410, causing the connecting cylinder 408 to move linearly along the threaded rod 407. This causes the connecting piece 409 to move along the connecting frame 411. At this time, the connecting frame 401 rotates around the fixed rod 402 under the action of the connecting frame 411. Since the solar reflector 2 is fixedly connected to the connecting frame 401, the elevation angle of the solar reflector 2 will be adjusted accordingly. When it is necessary to adjust the horizontal angle of the solar reflector 2, the positioning bolt 602 is disengaged from the threaded hole on the top surface of the base. Pushing the positioning bolt 602 causes the turntable 601 to rotate around the axis of rotation. Once the desired position is reached, the positioning bolt 602 is tightened back into the threaded hole on the top surface of the base.

[0035] When the focal point of the solar reflector 2 changes in the vertical direction, the height of the sliding rod 502 can be adjusted to adapt to the change in focal point. Hold the first fixed frame 503 with your hand, pull out the pin 511, slide the sliding rod 502 up and down, and when it reaches the appropriate position, insert the pin 511 again. When the reactor 3 has finished working, hold the second fixed frame 507 with your hand, pull out the pin 511, slide the sliding cylinder 506 upward, so that the second fixed frame 507 moves upward, and the reactor cover and stirring shaft separate from the reactor.

[0036] This invention is applicable to small experimental reaction vessels, such as laboratory beakers.

[0037] The following comparative experiments were conducted using other different light sources to demonstrate the invention.

[0038] The photodegradation reaction of methylene blue is illustrated below as an example. The concentration of the methylene blue aqueous solution is 10 mg / L, and the catalyst is MIL-88B(Fe). Synthesis method: Ferric chloride hexahydrate, terephthalic acid, and N,N-dimethylformamide are mixed evenly at a molar ratio of 1:1:200 and heated to 120°C in a hydrothermal reactor for 12 hours. Then, after cooling, filtration, solvent washing, and drying, MIL-88B(Fe) is obtained.

[0039] Take 50 mL of methylene blue aqueous solution, add 10 mg of MIL-88B(Fe), and place it in a reaction vessel for photodegradation. When an LED light source is placed at the bottom of the reaction vessel, replacing focused sunlight, the photodegradation time for methylene blue is 18 minutes. When a xenon lamp light source is placed at the bottom of the reaction vessel, replacing focused sunlight, the photodegradation time for methylene blue is 47 minutes. However, using the photocatalytic reaction device of this invention, the complete degradation time for methylene blue is 2.5 minutes. The device of this invention has the significant advantage of high photocatalytic efficiency.

[0040] The materials of the reaction vessel were compared during the completion of the above-mentioned photoreaction.

[0041] When using a colorless, transparent glass reactor, methylene blue completely degrades in 2.5 minutes; when using a colorless, transparent quartz reactor, it degrades completely in 1.5 minutes; when using a stainless steel reactor, it does not completely degrade within 24 hours; when using a brown transparent quartz reactor, it degrades completely within 60 minutes; and when using a frosted glass reactor, it degrades completely within 60 minutes. Therefore, the material of the reactor directly affects the effectiveness of the photoreaction.
