Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically a double-layer glass reaction vessel. Background Technology

[0002] Double-walled glass reactors are commonly used chemical reaction equipment in laboratories and pilot-scale operations. Their core structure consists of two glass bodies, inner and outer, and the sandwich design enables precise temperature control. They are suitable for various scenarios such as organic synthesis, drug development, and material preparation.

[0003] The double-layered glass reactor includes an inner vessel body, an outer vessel body, and a vessel jacket. The inner vessel body directly contacts the reactants, while the vessel jacket is the space formed between the outer and inner vessel bodies. Heating, cooling, or temperature control of the materials is achieved by circulating a heat transfer medium within the vessel jacket.

[0004] Through long-term use and observation, it was found that during the material reaction process using a double-walled glass reactor, uneven temperature distribution led to different reaction rates in different areas of the reactor. Some materials would over-react due to excessively high temperatures, while others would not react completely due to excessively low temperatures, thus affecting the overall reaction effect and product quality.

[0005] Therefore, this utility model provides a double-layered glass reactor. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a double-layered glass reactor according to an embodiment of this utility model includes a bottom plate 1; a back plate 11 is fixed to the middle of the side wall of the bottom plate 1; a top plate 12 is fixed to the top of the back plate 11; a lifting assembly is provided in the middle of the side wall of the top plate 12; an outer vessel body 13 is installed on the top of the bottom plate 1; an inner vessel body 14 is fixed to the middle of the inner side wall of the outer vessel body 13; a liquid delivery pipe 15 is assembled between the outer vessel body 13 and the inner vessel body 14; both ends of the liquid delivery pipe 15 are located outside the outer vessel body 13; a stirring assembly is provided between the outer vessel body 13 and the inner vessel body 14; a stirring assembly is provided on the top of the inner vessel body 14; a mixing assembly is provided on the top of the inner vessel body 14; the mixing assembly and the stirring assembly are correspondingly arranged; during operation, the experimenter pours the material to be reacted into the inner vessel body 14. Then, the lifting assembly is used to lower the stirring and mixing assemblies, which then cover the top of the inner vessel 14. The stirring and mixing assemblies are then activated again, and the materials inside the inner vessel 14 are evenly mixed together under the combined action of the stirring and mixing assemblies. When it is necessary to adjust the reaction temperature inside the inner vessel 14, the experimenter injects a liquid of appropriate temperature into the infusion pipe 15. When the liquid flows inside the infusion pipe 15, it will transfer the temperature to the inside of the inner vessel 14. At this time, the experimenter activates the stirring assembly, which will agitate the air between the outer vessel 13 and the inner vessel 14, so that the temperature transferred to the inside of the inner vessel 14 can evenly heat or cool the materials at each location.

[0027] like Figures 1 to 5As shown, the stirring assembly includes multiple grooves 2; the grooves 2 are formed on the side wall of the base plate 1; multiple fixing plates 21 are fixed between the outer vessel body 13 and the inner vessel body 14; a first motor 22 is mounted in the middle of the side wall of the fixing plate 21 and the groove 2; a movable shaft 23 is fixedly connected to the output end of the first motor 22; multiple fan blades 24 are fixed in the middle of the side wall of the movable shaft 23; the fan blades 24 are located between the outer vessel body 13 and the inner vessel body 14; during operation, the experimenter injects liquid at a suitable temperature into the infusion pipeline 15 according to the reaction requirements, and then starts the multiple first motors 22. The first motors 22 drive the movable shaft 23 to rotate, and when the movable shaft 23 rotates, it drives the multiple fan blades 24 to rotate synchronously. At this time, the multiple fan blades 24 will rotate from the top and... At the same time, the airflow between the outer vessel 13 and the inner vessel 14 is stirred at the bottom, so that the temperature transferred from the liquid delivery pipe 15 is evenly distributed in each area. This step, by setting the groove 2, the fixed plate 21, the first motor 22, the movable shaft 23 and the fan blades 24, helps to break the temperature gradient between the outer vessel 13 and the inner vessel 14, so that the airflow is evenly distributed between the outer vessel 13 and the inner vessel 14, and the temperature of each part in the reactor is consistent, thereby achieving uniform heating or cooling of the material in the reactor. Moreover, the stirring of the fan blades 24 can accelerate the flow of air between the outer vessel 13 and the inner vessel 14, making the temperature exchange between the airflow and the inner vessel 14 more rapid, thereby accelerating the temperature change rate of the material in the reactor.

[0028] like Figures 1 to 4 As shown, the stirring assembly includes a second motor 3; the second motor 3 is located between the top plate 12 and the inner vessel 14; a first movable top cover 31 is fixedly connected to the output end of the second motor 3; a first stirring rod 32 is fixed to the bottom of the first movable top cover 31; multiple stirring plates 33 are installed in the middle of the side wall of the first stirring rod 32; both the stirring plates 33 and the first stirring rod 32 are located inside the inner vessel 14; when the material reacts inside the inner vessel 14, the second motor 3 is started, and the second motor 3 will drive the first movable top cover 31 to rotate. When the first movable top cover 31 rotates... This will drive the first stirring rod 32 at its bottom to rotate. When the first stirring rod 32 rotates, it will drive multiple stirring plates 33 to rotate synchronously. At this time, the first stirring rod 32 and the stirring plates 33 are stirring the material inside the inner vessel 14. This step is equipped with a second motor 3, a first movable top cover 31, a first stirring rod 32 and stirring plates 33. Stirring the material can accelerate the full contact between the materials, shorten the diffusion path, and significantly improve the reaction rate. Stirring can also allow the material to fully exchange heat with the vessel wall, reduce local overheating or overcooling, and improve the temperature control accuracy.

[0029] like Figures 1 to 4As shown, the mixing assembly includes a second movable top cover 4; the second movable top cover 4 is rotatably connected to the side wall of the first movable top cover 31; a plurality of first protrusions 41 are fixed in the middle of the side wall of the second movable top cover 4; a plurality of second protrusions 42 are fixed in the middle of the side wall of the first movable top cover 31; the second protrusions 42 and the first protrusions 41 are correspondingly arranged; a second stirring rod 43 is fixed at the bottom of the second movable top cover 4; the second stirring rod 43 is located inside the inner vessel body 14; the first protrusions 41 and the second protrusions 42 are slidably connected to the middle of their side walls by limit rings 44; because the second protrusions 42 and the first protrusions 41 are correspondingly arranged, when the first movable top cover 31 reciprocates, the first movable top cover 31 will drive the plurality of second protrusions 42 to rotate, at which time the second protrusions 42 will move along the limit rings. 44 Sliding, when the second protrusion 42 contacts the first protrusion 41, it will drive multiple first protrusions 41 to rotate. At this time, the first protrusions 41 will drive the second movable top cover 4 to rotate, so that the second movable top cover 4 will drive the second stirring rod 43 at its bottom to rotate. At this time, multiple second stirring rods 43 will stir the material inside the inner vessel 14. This step of setting the second movable top cover 4, the first protrusion 41, the second protrusion 42, the second stirring rod 43 and the limiting ring 44 can break the material agglomeration through shear force, so that the reactant molecules can fully collide, increase the gas-liquid interface area, improve gas solubility, and further improve the reaction rate. At the same time, this setting can prevent high viscosity materials from scaling on the vessel wall, reduce cleaning difficulty and equipment corrosion risk, and extend the service life of the vessel.

[0030] like Figure 1 and Figure 2 As shown, the lifting assembly includes an electric push rod 5; the electric push rod 5 is mounted on the top of the top plate 12; the output end of the electric push rod 5 is fixedly connected to the second motor 3; a slot 51 is opened in the middle of the side wall of the back plate 11; a limit rod 52 is fixed in the middle of the inner side wall of the slot 51; a limit rod 52 is slidably connected in the middle of the side wall of the limit rod 52; a connecting rod 53 is fixed between the limit rod 52 and the electric push rod 5; during operation, the experimenter starts the electric push rod 5, and the electric push rod 5 will drive the second motor 3 to move under the restriction of the connecting rod 53, so that the second motor 3 drives the stirring assembly and mixing assembly at its bottom to move simultaneously. This step, by setting the electric push rod 5, the slot 51, the limit rod 52 and the connecting rod 53, can automatically lift the stirring assembly and mixing assembly to the outside of the vessel, reducing the tediousness of manual disassembly and the safety accidents caused by high temperature burns or residual pressure inside the vessel.

[0031] like Figures 1 to 4 As shown, multiple sealing strips 6 are fixed between the first movable top cover 31 and the second movable top cover 4; the sealing strips 6 are made of elastic material; this step can reduce the leakage of materials inside the inner vessel 14 to the outside by setting the sealing strips 6, protect the safety of experimental personnel and reduce environmental pollution.

[0032] like Figure 1 , Figure 2 , Figure 3and Figure 5 As shown, a heat insulation pad 7 is fixed in the middle of the side wall of the outer vessel 13; the heat insulation pad 7 is made of elastic material; this step can evenly distribute the surface temperature of the vessel by setting the heat insulation pad 7, reduce the concentration of glass thermal stress caused by local overheating or overcooling, and reduce the risk of vessel cracking.

[0033] Working principle: The experimenter pours the materials to be reacted into the inner vessel 14, then uses the lifting component to lower the stirring and mixing components. At this time, the stirring and mixing components will cover the top of the inner vessel 14. Then, the stirring and mixing components are activated again. The materials inside the inner vessel 14 will be evenly mixed together under the combined action of the stirring and mixing components. When it is necessary to adjust the reaction temperature inside the inner vessel 14, the experimenter injects a liquid of appropriate temperature into the infusion pipe 15. When the liquid flows inside the infusion pipe 15, it will transfer the temperature to the inside of the inner vessel 14. The experimenter activates the stirring assembly, which agitates the air between the outer vessel 13 and the inner vessel 14, allowing the temperature transferred to the inner vessel 14 to evenly heat or cool the materials at various locations. The experimenter then injects liquid at a suitable temperature into the infusion pipe 15 according to the reaction requirements. Subsequently, multiple first motors 22 are activated, driving the movable shaft 23 to rotate. The rotation of the movable shaft 23 causes multiple fan blades 24 to rotate synchronously. At this time, the multiple fan blades 24 simultaneously agitate the airflow between the outer vessel 13 and the inner vessel 14 from both the top and bottom, thus agitating the material flowing from the infusion pipe. The temperature transmitted through pipe 15 is evenly distributed across various areas. When the material reacts inside the inner vessel 14, the second motor 3 is activated. The second motor 3 drives the first movable top cover 31 to rotate. When the first movable top cover 31 rotates, it drives the first stirring rod 32 at its bottom to rotate. The rotation of the first stirring rod 32 drives multiple stirring plates 33 to rotate synchronously. At this time, the first stirring rod 32 and the stirring plates 33 are all stirring the material inside the inner vessel 14. Because the second protrusion 42 and the first protrusion 41 are correspondingly set, when the first movable top cover 31 reciprocates, it drives multiple... The second protrusion 42 rotates, and at this time the second protrusion 42 will slide along the limiting ring 44. When the second protrusion 42 contacts the first protrusion 41, it will drive multiple first protrusions 41 to rotate. At this time, the first protrusion 41 will drive the second movable top cover 4 to rotate, so that the second movable top cover 4 will drive the second stirring rod 43 at its bottom to rotate. At this time, multiple second stirring rods 43 will stir the material inside the inner vessel 14. The experimenter starts the electric push rod 5. The electric push rod 5 will drive the second motor 3 to move under the restriction of the connecting rod 53, so that the second motor 3 will drive the stirring component and mixing component at its bottom to move simultaneously.
