Description

Technical Field

[0001] This utility model relates to the field of photonic crystal preparation technology, specifically to a temperature-controlled reaction vessel for preparing photonic crystals using colloidal microspheres. Background Technology

[0002] A photonic crystal is an optical structure that forms due to Bragg scattering at the interface of different dielectrics. When light waves propagate within a photonic crystal, a photonic bandgap is created. This bandgap blocks photons of specific frequencies from propagating, affecting their motion and resulting in a regular optical structure made up of media with different refractive indices arranged periodically. Early methods for preparing photonic crystals, such as etching, machining, stacking, and laser interferometry, required advanced processing techniques. These methods were complex and cumbersome, with long processing cycles and small fabrication areas, limiting their application to large-area fabrication. In contrast, self-assembly methods can achieve ordered assembly without external intervention. Because this method does not require high precision in experimental instruments or advanced personnel skills, it has become one of the most commonly used methods for preparing photonic crystals in laboratories. Based on different inducing factors during the self-assembly process, it can be classified into field-induced self-assembly, evaporation-induced self-assembly, and template-guided self-assembly.

[0003] Colloidal microspheres are used as basic building blocks in the fabrication of photonic crystals. Therefore, the fabrication of colloidal microspheres is a prerequisite for the fabrication of photonic crystals. A reaction vessel is used in the fabrication of colloidal microspheres. Currently, the reaction vessel is usually heated directly by an electric heating wire. As a result, the temperature may vary in different locations, leading to inconsistent reaction and assembly of colloidal microspheres in different regions, which affects the uniformity and consistency of the photonic crystal.

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a temperature-controlled reaction vessel for preparing colloidal microspheres for photonic crystals, comprising a vessel body 1, a vessel cover 2, a vessel sleeve 3, a heating wire 4, a water inlet pipe 5, a drain pipe 6, a feed pipe 7, a discharge pipe 8, a support frame 9, a stirring rod 10, a lower cylinder 11, an upper cylinder 12, a motor 13, a guide block 14, and a locking block 15.

[0031] The upper surface of the vessel body 1 is open. A vessel cover 2 is bolted to the top of the vessel body 1. A feed pipe 7 is inserted through the surface of the vessel cover 2. A discharge pipe 8 is inserted through the lower surface of the vessel body 1. Valves are installed inside the feed pipe 7 and the discharge pipe 8. A heating structure is installed on the outer surface of the vessel body 1. The heating structure forms a water bath structure on the outer surface of the vessel body 1 through the vessel sleeve 3, making the heating process of the vessel body 1 more uniform. The heating structure includes the vessel sleeve 3, which is fixedly wrapped around the outer surface of the vessel body 1. The vessel sleeve 3 is a hollow double-layer structure. A heating wire 4 is installed inside the vessel sleeve 3. A sealed chamber is formed between the inner surface of the vessel sleeve 3 and the outer surface of the vessel body 1. The chamber between the outer surface of the vessel body 1 and the inner surface of the vessel sleeve 3 is marked as the water bath chamber. A water inlet pipe 5 is inserted through the side surface of the vessel sleeve 3. A drain pipe 6 is inserted through the lower surface of the vessel sleeve 3. Both the water inlet pipe 5 and the drain pipe 6 are inserted into the water bath chamber. Valves are installed inside the water inlet pipe 5 and the drain pipe 6.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the valve of the water inlet pipe 5 is opened, and water is injected into the water bath chamber formed by the vessel sleeve 3 through the water inlet pipe 5. After the water is injected, the valve of the water inlet pipe 5 is closed, and the valve of the feed pipe 7 is opened to introduce the raw materials required for the preparation of colloidal microspheres into the vessel body 1 through the feed pipe 7. The heating wire 4 is turned on, and the heating wire 4 heats the water in the water bath chamber. The heat is evenly transferred to the vessel body 1, thereby heating the raw materials in the vessel body 1 evenly. This allows for precise control of the water temperature in the water bath chamber, thereby achieving precise control of the reaction temperature of the vessel body 1. This ensures that the colloidal microspheres are in a suitable and uniform temperature environment during the preparation process, thus improving the quality of the photonic crystal.

[0033] The vessel body 1 is equipped with a stirring structure inside. The stirring structure uses a lower cylinder 11 and an upper cylinder 12, which are separately set, to stir the material while facilitating the disassembly and cleaning of the vessel body 1. The stirring structure includes a support frame 9, which is a hollow circular structure. The support frame 9 is rotatably mounted on the bottom surface of the vessel body 1. A stirring rod 10 is fixedly connected to the outer surface of the support frame 9. The lower cylinder 11 is fixedly connected to the upper surface of the support frame 9. A connecting rod connects the lower cylinder 11 and the stirring rod 10. A cross-shaped groove is provided at the upper end of the lower cylinder 11. The upper cylinder 12 is engaged in the groove at the upper end of the lower cylinder 11. A cross-shaped protrusion is provided at the lower end of the upper cylinder 12. The upper cylinder 12 is fixedly connected to the output end of the motor 13. The motor 13 is fixedly mounted on the upper surface of the vessel cover 2.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, when the material reacts inside the vessel 1, the motor 13 is started, which drives the upper cylinder 12 to rotate. The upper cylinder 12 drives the lower cylinder 11 to rotate, and the rotating lower cylinder 11 drives the support frame 9 to rotate. The support frame 9 drives the stirring rod 10 to rotate. The rotating stirring rod 10 is used to stir and mix the material inside the vessel 1. When it is necessary to clean the vessel 1, the vessel 1 and the lid 2 are disassembled and separated. The lid 2 is pulled outward, and the lid 2 drives the upper cylinder 12 and the lower cylinder 11 to separate. At this time, the inside of the vessel 1 can be cleaned. After cleaning, the protrusion on the surface of the upper cylinder 12 is reconnected with the cross-shaped groove at the upper end of the lower cylinder 11 to complete the installation of the vessel 1.

[0035] The interior of the vessel body 1 is provided with a guiding feeding structure. The guiding feeding structure guides the raw material falling from the feed pipe 7 through the guide block 14. The guiding feeding structure includes the guide block 14, which is an inverted conical structure. The upper and lower surfaces of the guide block 14 are open. A circular through hole is provided through the lower surface of the guide block 14. The circular through hole of the guide block 14 passes through the outer surface of the upper cylinder 12. The outer surface of the guide block 14 contacts the inner wall of the vessel body 1. A locking block 15 is fixedly installed on the inner wall of the vessel body 1. The locking block 15 is circular and contacts the lower surface of the guide block 14.

[0036] like Figure 5 and Figure 6 As shown, during the raw material feeding process, the raw material enters the vessel body 1 through the feed pipe 7 and falls downward onto the surface of the guide block 14. The inverted conical guide block 14 allows the raw material to fall from the lower opening of the guide block 14, thereby concentrating the raw material in the center of the vessel body 1 and preventing the raw material from adhering to the inner wall of the vessel body 1.

[0037] Working principle: When using this photonic crystal-based colloidal microsphere preparation temperature-controlled reactor, water is injected into the water bath between the vessel sleeve 3 and the vessel body 1 through the water inlet pipe 5. The raw materials required for preparing colloidal microspheres are injected into the vessel body 1 through the feed pipe 7. Under the guidance of the guide block 14, the raw materials fall to the center of the vessel body 1. The heating wire 4 is activated to heat the water in the water bath, so that the heat is evenly transferred to the vessel body 1 to heat the raw materials. The motor 13 is activated, and the motor 13 drives the upper cylinder 12 to rotate. The upper cylinder 12 drives the lower cylinder 11 to rotate. The rotating lower cylinder 11 drives the stirring rod 10 to rotate and stir the raw materials, so that the materials are fully mixed, promote the uniform reaction, and increase the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
