Description

Technical Field

[0001] This utility model relates to the technical field of programmable cooling devices, and in particular to a programmable cooling device for photoinitiator crystallization. Background Technology

[0002] Photoinitiators are compounds that can generate active free radicals or cations under specific wavelengths of light. The crystallization and purification of photoinitiators after synthesis is a key process step. Photoinitiator molecules usually have thermal sensitivity and complex solubility characteristics. Traditional natural cooling can easily lead to uncontrollable crystallization rate, causing problems such as unstable crystal form, inclusion of impurities, or excessively fine crystal grains. However, programmable cooling devices can significantly improve product yield and batch consistency by precisely adjusting the temperature curve, allowing the solution to crystallize orderly from a supersaturated state along a preset path, thus meeting the stringent requirements of the photocuring industry for material performance.

[0003] A search of Chinese patent publication number "CN216083516U" reveals "a programmable cooling box for real-time temperature monitoring". This programmable cooling box for real-time temperature monitoring has a temperature probe structure set inside the box cover. During the use of the programmable cooling box, the internal temperature of the programmable cooling box can be monitored in real time, and the internal temperature changes of the programmable cooling box can be understood in a timely manner, making it more convenient to use.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The photoinitiator gradually reaches a supersaturated state during the cooling process, but the supersaturation of different areas of the solution may be inconsistent. When using the programmable cooling box, it is impossible to mix the solutions processed inside to ensure the solution concentration balance, which can easily reduce its crystallization rate and is not conducive to the crystallization of the photoinitiator. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a programmable cooling device for photoinitiator crystallization, which solves the technical problem that existing devices are not suitable for use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A programmable cooling device for photoinitiator crystallization includes a programmable cooling device body, wherein a cooling chamber is provided inside the programmable cooling device body.

[0010] The cooling cavity is symmetrically and fixedly installed with cooling structures inside.

[0011] The cooling structure includes a support frame, on the inner side of which a first base plate, a second base plate, and a third base plate are fixedly installed. The first base plate, the second base plate, and the third base plate are stacked sequentially from bottom to top. An electric push rod is provided inside the third base plate. An extension block is fixedly installed on the output shaft of the electric push rod. The extension block is slidably installed with the second base plate. U-shaped blocks are fixedly installed on the side wall of the output shaft of the electric push rod and on the side wall of the extension block. A motor is fixedly installed inside each of the two U-shaped blocks.

[0012] Preferably, the output shafts of both motors are rotatably mounted to the U-shaped block, a disc is fixedly mounted on the output shafts of both motors, a through groove group is opened inside the two discs, a fan blade main shaft is fixedly mounted at the center of the lower end of the two discs, a threaded groove is opened inside the two discs, and the two threaded grooves are located outside the through groove group.

[0014] (III) Beneficial Effects

[0015] Firstly, by turning on the motor, the fan blades on the disc can be rotated, and through the through-slot assembly, the liquid inside the container can be cooled quickly, increasing the cooling rate. At the same time, by setting an electric push rod, the electric push rod can drive the U-shaped block to move downward, thereby reducing the distance between the fan blades and the container, improving the convection heat dissipation effect, and further facilitating the cooling of the container.

[0016] Secondly, by installing a stirring rod at the lower end of the disc, the rotation of the disc when the motor starts will drive the stirring rod to rotate as well.

Simultaneously, by setting an electric push rod, the electric push rod can drive the U-shaped block downward, thereby reducing the distance between the fan blade shaft and the container, improving the convection heat dissipation effect, further facilitating the cooling process of the container. Furthermore, by setting a stirring rod at the lower end of the disc, when the motor starts, the rotation of the disc will drive the stirring rod to rotate as well.

[0024] Example

[0025] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing devices are not conducive to use. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a programmable cooling device for photoinitiator crystallization, including a programmable cooling device body 11, and a cooling chamber 12 is provided inside the programmable cooling device body 11.

[0027] Cooling structures are symmetrically and fixedly installed inside the cooling chamber 12;

[0028] The cooling structure includes a bracket 13. A first base plate 14, a second base plate 15, and a third base plate 16 are fixedly installed on the inner side of the bracket 13. The first base plate 14, the second base plate 15, and the third base plate 16 are stacked sequentially from bottom to top. An electric push rod 17 is provided inside the third base plate 16. An extension block 18 is fixedly installed on the output shaft of the electric push rod 17. The extension block 18 is slidably installed with the second base plate 15. U-shaped blocks 19 are fixedly installed on the side wall of the output shaft of the electric push rod 17 and the side wall of the extension block 18. Motors 21 are fixedly installed inside the two U-shaped blocks 19. The output shafts of the two motors 21 are rotatably installed with the U-shaped blocks 19. A disc 22 is fixedly installed on the output shaft of the two motors 21. A through slot group 23 is opened inside the two discs 22. A fan blade main shaft 24 is fixedly installed at the center of the lower end of the two discs 22.

[0029] By turning on the motor 21, the motor 21 can drive the fan blade main shaft 24 on the disk 22 to rotate, and through the through groove assembly 23, the liquid inside the container 31 can be cooled quickly, increasing the cooling rate. At the same time, by setting the electric push rod 17, the electric push rod 17 can drive the U-shaped block 19 to move downward, thereby reducing the distance between the fan blade main shaft 24 and the container 31, which further facilitates the cooling process of the container 31.

[0030] Both discs 22 have threaded grooves 25 inside, and both threaded grooves 25 are located outside the through groove group 23. Both discs 22 have stirring rods 26 at their lower ends, and both stirring rods 26 have threaded posts 27 fixedly installed at their upper ends. Both threaded posts 27 are threaded inside the threaded grooves 25.

[0031] By setting a stirring rod 26 at the lower end of the disc 22, when the motor 21 starts, the rotation of the disc 22 will drive the stirring rod 26 to rotate as well. By setting an electric push rod 17, the electric push rod 17 can drive the U-shaped block 19 downward, so that the stirring rod 26 enters the container 31, thereby stirring and mixing the solution inside the container 31. Combined with the air blowing treatment of the fan blade main shaft 24, the cooling rate of the solution can be greatly improved, and the problem of local temperature difference can be avoided, thus improving the treatment effect of the solution.

[0032] The surface of the main body 11 of the programmable cooling device is provided with a cabinet door 28 and a control unit 29. The first base plate 14 and the second base plate 15 are both embedded with a container 31. The two containers 31 are located below the fan blade main shaft 24 and the stirring rod 26.

[0033] In use, the operator first places the solution to be crystallized into the container 31 and embeds the container 31 into the first base plate 14 and the second base plate 15. Then, according to the process requirements of the solution to be crystallized, the operator can start the programmable cooling device body 11 through the control unit 29 to cool the inside of the cooling chamber 12.

[0034] Working principle:

[0035] The first step is to place the solution to be crystallized into the container 31 and embed the container 31 into the first base plate 14 and the second base plate 15. Then, according to the process requirements of the solution to be crystallized, the programmable cooling device body 11 can be activated by the control unit 29 to cool the inside of the cooling chamber 12.

[0036] In the second step, the operator can then activate the electric push rod 17 via the control unit 29. This causes the output shaft of the electric push rod 17 to lower the extension block 18, which in turn lowers the U-shaped block 19. Once the stirring rod 26 is inside the container 31, the electric push rod 17 will be deactivated, and the motor 21 will be activated. The motor 21 will then drive the stirring rod 26 via the disc 22 to stir and mix the solution inside the container 31. Simultaneously, the rotation of the disc 22 will drive the fan blade main shaft 24 to rotate, and air will be introduced through the channel assembly 23. This allows the fan blade main shaft 24 to convect and dissipate heat on the surface of the container 31, further increasing the cooling rate. Once the cooling process is complete, the electric push rod 17 will automatically raise the stirring rod 26 to prevent crystal breakage.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
