Description

Technical Field

[0001] The present invention relates to the technical field of photocatalysis, and specifically to a photocatalytic organic synthesis reaction device. Background Art

[0002] In the field of chemical research, photocatalytic organic synthesis reaction, as an efficient and environmentally friendly synthesis method, has received extensive attention and application in recent years. This technology uses light energy to excite the catalyst and promote the chemical reaction between organic compounds, thereby realizing the synthesis of new substances. However, despite the many advantages of photocatalytic organic synthesis reaction, the design of the reaction device in its practical application faces some challenges.

[0003] A photocatalytic organic synthesis reaction device currently available on the market, although meeting the basic experimental requirements to a certain extent, still has significant deficiencies in terms of applicability and reaction rate. A major problem is that these devices often cannot well adapt to reaction test tubes of different sizes. Due to the diverse sizes of reaction test tubes and the lack of a flexible adjustment mechanism in existing devices, the stability of the test tubes in the device is poor. During the synthesis reaction process, this unstable situation is likely to cause the test tubes to shake, which not only increases the risk of test tube damage but also may affect the accuracy and repeatability of the reaction.

[0004] In addition, uneven light irradiation is also a significant defect of existing photocatalytic organic synthesis reaction devices. The efficiency of photocatalytic reactions depends to a large extent on the uniform distribution of light energy. However, due to limitations in device design, such as fixed light source position and limited light irradiation angle in the reaction area, the light irradiation distribution is uneven throughout the catalytic process. Some areas may receive too much light, while another part receives insufficient light. This uneven light irradiation phenomenon not only reduces the synthesis rate but may also trigger side reactions, affecting the purity and yield of the final product. Summary of the Invention

The top of the connecting rod is movably connected to a linkage rod. The top end of the linkage rod is fixedly connected to a threaded block. A threaded hole is formed in one side of the threaded block, and a threaded rod is threadedly connected inside the threaded hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The device adopts a transmission method combining an electric telescopic rod and a threaded rod. Through the telescopic action of the electric telescopic rod, the meshing connection between the first bevel gear and multiple second bevel gears is realized, so as to drive the threaded rod to rotate through multiple second bevel gears, and then drive the clamping device to act, realizing the rapid and precise clamping and release of the reaction test tube. This transmission mechanism has a rapid response and simple operation, significantly improving the efficiency of the reaction operation.

[0018] 2. The driving motor is connected to the first gear through a rotating rod to form a power transmission chain. When the driving motor is started, the rotating rod rotates accordingly. Through the meshing action between the gears, the power is transmitted to the double-headed gear and the second gear, and then drives the light screen to rotate. This transmission process is stable and reliable, ensuring the uniform rotation of the light screen and improving the efficiency of photocatalysis.

[0019] 3. The clamping device adopts a transmission method combining a linkage rod and a threaded block. Through the threaded connection between the threaded rod and the threaded block, the precise control of the clamping force is realized. When the threaded rod rotates, the threaded block drives the linkage rod to move, and then drives the clamping rod to clamp the test tube through the connecting rod and the rotating frame. This transmission design makes the clamping force evenly distributed, effectively preventing the test tube from cracking due to excessive extrusion.

[0020] 4. The connection between the lifting cap and the rotating rod is achieved through a limiting block and a sliding groove, ensuring the stability of the lifting cap during rotation. At the same time, the design of the compression spring provides the lifting function for the lifting cap, enabling the first bevel gear to automatically separate from multiple second bevel gears, thereby realizing the automatic adjustment of the clamping device.

[0021] 5. The device supports the adjustment of various transmission parameters through the control console, such as the rotation speed, steering of the drive motor, the telescopic stroke of the electric telescopic rod, etc. Users can flexibly adjust these parameters according to experimental requirements to meet the clamping needs of different test tube specifications and sizes. At the same time, the device also supports the adjustment of parameters such as light intensity and light time, further enhancing the flexibility and customizability of the synthesis reaction.

The double-headed gear 13 is meshed with a second gear 12 on one side. A rotating bearing 14 is fixedly connected to the inner wall of the second gear 12.

[0038] Furthermore, each of the plurality of clamping devices includes a threaded rod 22, a threaded block 23, a linkage rod 24, a connecting rod 25, a rotating frame 26, a clamping rod 27 and a limiting block 28. A rotating frame 26 is rotatably connected to the top of the placement plate 7. One side of the rotating frame 26 is fixedly connected to a connecting rod 25.

[0040] Furthermore, a movable groove is formed in the top of the connecting rod 25, and the bottom end of the linkage rod 24 is movably connected to the inside of the movable groove.

[0042] Furthermore, the rubber block 29 is cylindrical, and a pressure sensor is fixedly installed inside the rubber block 29.

[0043] When the embodiment of the present application is in use: When using this device, first place the reaction test tube inside the placement hole of the placement tray 7, then place the bottom of the reaction test tube through the tray 8, and then cover the synthesis chamber door 4. Control the movable end of the electric telescopic rod 17 to expand and contract through the control console 2, so that the movable end of the electric telescopic rod 17 presses down the lifting cap 19 downward, causing the lifting cap 19 to drive the first bevel gear 20 to move downward. At the same time, the lifting cap 19 squeezes the compression spring 18, so that the two limit blocks on the rotating rod 10 move inside the sliding groove of the lifting cap 19. Then the first bevel gear 20 moves downward, causing the tooth end of the first bevel gear 20 to mesh with the tooth end of the second bevel gear 21. Then control the movable end of the driving motor 9 to rotate through the control console 2, so that the movable end of the driving motor 9 drives the rotating rod 10 to rotate. Thus, under the action of the two limit blocks, the lifting cap 19 is driven to rotate, causing the lifting cap 19 to drive the first bevel gear 20 to rotate. Through the meshing connection between the first bevel gear 20 and multiple second bevel gears 21, the first bevel gear 20 drives multiple second bevel gears 21 to rotate, causing the second bevel gear 21 to drive the threaded rod 22 to rotate. Utilizing the threaded connection between the threaded rod 22 and the threaded block 23, the threaded block 23 drives the linkage rod 24 to move. Then, through the movable grooves on the linkage rod 24 and the connecting rod 25, the linkage rod 24 rotates the rotating frame 26 through the connecting rod 25, causing the rotating frame 26 to drive the clamping rod 27 to rotate through the limit block 28, so that one end of the clamping rod 27 performs a circular motion around the fixed rod 30. Thus, one end of the clamping rod 27 drives the rubber block 29 to clamp the reaction test tube. Utilizing the rubber material of the rubber block 29, damage caused by excessive clamping force can be avoided. Then, through the pressure sensor inside the rubber block 29, when the rubber block 29 clamps the reaction test tube, control the movable end of the electric telescopic rod 17 to rise through the control console 2, so that under the elastic force of the compression spring 18, the lifting cap 19 drives the first bevel gear 20 to rise, causing the first bevel gear 20 to disengage from the second bevel gear 21, thereby stopping the second bevel gear 21 from rotating, and thus causing the clamping rod 27 to stop clamping the reaction test tube. Then, when the rotating rod 10 rotates, it will drive the first gear 11 to rotate. Through the meshing connection between the first gear 11 and the double-headed gear 13, the double-headed gear 13 is driven to rotate. Utilizing the meshing connection between the double-headed gear 13 and the second gear 12, the double-headed gear 13 drives the second gear 12 to rotate, causing the second gear 12 to drive the light screen 15 to rotate through the transmission bearing 14. The light screen 15 can uniformly perform photocatalysis on the synthesis in the reaction test tube, thereby accelerating the synthesis rate.
