Technical Field
[0001] This utility model relates to the field of double-layer glass reactor technology, specifically a double-layer glass reactor capable of continuous concentration operation. Background Technology
[0002] Double-walled glass reactors are commonly used reaction equipment in laboratories and industrial production. They consist of two layers of glass, with the inner layer holding the reaction solvent and stirring for the reaction, while the outer layer can be circulated with a heat source for heating or cooling. This design allows chemical reactions to be carried out in a closed environment under normal or negative pressure conditions, and enables the reflux and distillation of the reaction solution. Double-walled glass reactors typically have good visibility characteristics, making it easy to observe the reaction process, and can perform high-temperature, low-temperature, and even vacuum reactions. They are suitable for fields such as fine chemicals, biopharmaceuticals, and the synthesis of new materials.
[0003] An investigation revealed that a Chinese patent discloses a sustainable double-layer glass reactor (publication number: CN208612394U), which includes a mounting frame. A fixing plate is provided at the bottom of the mounting frame, and a double-layer reactor body is mounted on the fixing plate. A discharge valve is provided at the bottom end of the double-layer reactor body. An upper pressure cover is movably connected to the top of the double-layer reactor body via a hinge. A motor is fixed in the middle of the upper pressure cover. The output end of the motor passes through the double-layer reactor body and is connected to a stirring rod through a coupling. A fixing rod is provided at one end of the upper pressure cover. The fixing rod is welded to the inside of the mounting frame, and a universal clamp is provided at the top of the fixing rod. A condenser is fixedly connected to one end of the universal clamp.
[0004] In the aforementioned patent, the solvent evaporated from the double-layered glass reactor is condensed into liquid by a condenser and flows into the storage tank via a storage tank and a micro water pump. One end of the storage tank is connected to a liquid recovery tank via a micro water pump, facilitating timely cleaning of the liquid in the storage tank and preventing liquid backflow into the reactor, thus enabling the double-layered glass reactor to operate continuously. The stirring blades on the stirring rod are directly fixed to the stirring rod. In existing technologies, double-layered glass reactors are often designed with a top diameter smaller than the main body. This design ensures the reactor's sealing and structural strength, but during installation, the stirring blades may bump into the reactor body, affecting the equipment's lifespan. Therefore, the design of directly fixing the stirring blades to the stirring rod requires operators to be extremely careful during installation, increasing the difficulty of installation.
[0005] Therefore, this invention provides a double-layered glass reactor capable of continuous concentration operations to solve the above-mentioned problems. Summary of the Invention

[0022] 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.
[0023] This invention provides a double-layered glass reactor capable of continuous concentration operations, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the reactor includes a mounting frame 1, a reactor body 2 disposed inside the mounting frame 1, a rotating shaft 13 rotatably mounted inside the reactor body 2, a sleeve rod 12 slidably mounted on the rotating shaft 13, a first limiting ring 16 fixedly mounted on the rotating shaft 13 and abutting one end of the sleeve rod 12, a stirring rod 14 rotatably mounted on one end of the rotating shaft 13, a traction rod 15 rotatably mounted on one end of the sleeve rod 12 near the first limiting ring 16, and a fixing mechanism disposed on the sleeve rod 12 for fixing the sleeve rod 12. The end of the traction rod 15 away from the sleeve rod 12 is movably connected to one side of the stirring rod 14. A slide bar is fixedly connected inside the sleeve rod 12, and a sliding groove adapted to the slide bar is provided on the rotating shaft 13.
[0024] The reactor body 2 of the reactor is a double-layered glass reactor. The sleeve rod 12 moves vertically on the rotating shaft 13, which can drive the stirring rod 14 used to stir the material inside the reactor body 2 through the traction rod 15. This causes the stirring rod 14 to move closer to the rotating shaft 13 to reduce the space occupied. Since the sleeve rod 12 also rotates when the rotating shaft 13 rotates with the stirring rod 14, the sliding strip inside the sleeve rod 12 and the sliding groove on the rotating shaft 13 can not only provide stability when the sleeve rod 12 moves, but also enable the rotating shaft 13 to drive the sleeve rod 12 to rotate.
[0025] Furthermore, in order to fix the lever 12, such as Figure 2 , Figure 3 and Figure 5 As shown, the fixing mechanism includes a fixing shell 17 sleeved on the sleeve rod 12, an adjusting rod 18 slidably installed inside the fixing shell 17, a second limiting ring 20 fixedly installed on the adjusting rod 18, and a spring 19 sleeved on the adjusting rod 18.
[0026] Two fixed housings 17 are provided, which are rotatably connected to each other and fixed to the sleeve rod 12 by a connector. The fixed housing 17 has a protrusion inside, and the sleeve rod 12 has a groove. The protrusion and the groove correspond to each other, which improves the stability of the fixed housing 17 installed on the sleeve rod 12. In addition, the sleeve rod 12 has a circular groove corresponding to the adjusting rod 18, and the rotating shaft 13 has two identical circular grooves. There is a certain distance between the two circular grooves on the rotating shaft 13. When the fixed housing 17 is installed on the fixed housing 17, the adjusting rod 18 can be inserted into one of the circular grooves on the rotating shaft 13 through the circular groove on the sleeve rod 12, so as to fix the sleeve rod 12 on the rotating shaft 13.
[0027] Furthermore, in order to improve the stability of the adjusting rod 18 during operation, such as Figure 2 , Figure 3 and Figure 5 As shown, one end of the spring 19 is fixedly connected to one side of the second limiting ring 20, and the other end of the spring 19 is fixedly installed inside the fixed housing 17.
[0028] The spring 19 is designed so that its own force can push the adjusting rod 18 through the second limiting ring 20, so that it is always inserted into one of the circular slots on the rotating shaft 13 through the circular slot on the sleeve 12.
[0029] In order for the rotating shaft 13 to drive the stirring rod 14 to stir the material in the vessel, such as Figure 1 , Figure 2 and Figure 3 As shown, the top of the reactor body 2 is fixedly connected to the reactor cover 8 via a connector. A rubber ring 10 is provided between the reactor body 2 and the reactor cover 8. The sleeve rod 12 and the rotating shaft 13 both pass through the reactor cover 8. The top of the mounting frame 1 is fixedly connected to the motor 3. The output end of the motor 3 passes through the mounting frame 1 and is fixedly connected to one end of the rotating shaft 13 that passes through the reactor cover 8.
[0030] The output end of motor 3 is connected to rotating shaft 13. After motor 3 is started, motor 3 can provide rotational power to rotating shaft 13, driving rotating shaft 13 to drive sleeve rod 12 and stirring rod 14 to stir the material.
[0031] It should be noted that, in order for reactor body 2 to operate continuously, such as Figure 1 and Figure 2 As shown, the condenser 5 is fixedly connected to the mounting frame 1 via the mounting bracket. The inner cavity of the condenser 5 is connected to the inner cavity of the reactor body 2 via a connecting pipe that passes through the reactor cover 8. The water pump 6 is fixedly connected to the mounting frame 1 via the mounting bracket. The collection box 7 is movably connected to the mounting frame 1 via the mounting bracket. The water pump 6 is connected to the inner cavity of the condenser 5 via a water pipe. The collection box 7 is located in the lower middle part of the water pump 6.
[0032] The solvent evaporated from the reactor body 2 turns into liquid upon contact with the condenser 5, and then flows to the bottom of the condenser 5. The liquid can be transported to the collection box 7 by the water pump 6, so that the liquid in the collection box 7 can be cleaned up in time, ensuring that the reactor body 2 can continue to operate.
[0033] Furthermore, to facilitate the use of the reaction vessel by staff, such as... Figure 1 , Figure 2 and Figure 3 As shown, a vacuum gauge 9 is fixedly connected to the top of the vessel lid 8, a rubber pad 4 is fixedly connected to the inside of the mounting frame 1, the bottom of the reactor body 2 is fixedly connected to the inside of the rubber pad 4, and a discharge valve 11 connected to the inner cavity of the reactor body 2 is fixedly connected to the bottom of the reactor body 2. The discharge valve 11 passes through the rubber pad 4.
[0034] A vacuum gauge 9 is installed on the top of the vessel lid 8. The vacuum gauge 9 is used to detect the vacuum state inside the reactor body 2 to prevent the vacuum state from being damaged and affecting the operation results. After the operation is completed, the material is unloaded by opening the discharge valve 11 at the bottom of the reactor body 2.
[0035] The aforementioned fixed shell 17, adjusting rod 18, spring 19, and second limiting ring 20 can be considered as a single unit. When installing or replacing components such as sleeve rod 12, rotating shaft 13, and stirring rod 14, the sleeve rod 12 and rotating shaft 13 can first pass through the vessel cover 8. Then, the fixed shell 17 and adjusting rod 18 are installed on the sleeve rod 12. The sleeve rod 12 is dragged to slide on the rotating shaft 13, causing the stirring rod 14 to move closer to the rotating shaft 13 until the adjusting rod 18 is inserted into the higher circular groove on the rotating shaft 13 through the circular groove on the sleeve rod 12. In the tank, the sleeve rod 12 and the rotating shaft 13 are in a fixed state, and the stirring rod 14 is also close to the rotating shaft 13 to reduce the space occupied. At this time, the lid 8 can be placed on the top of the reactor body 2. At the same time, the rotating shaft 13 is adjusted so that the rotating shaft 13 is connected to the motor 3. Then, the adjusting rod 18 is pulled so that the adjusting rod 18 moves out of the circular groove inside the rotating shaft 13. At the same time, the sleeve rod 12 is moved down until the adjusting rod 18 is inserted into the lower circular groove on the rotating shaft 13 through the circular groove on the sleeve rod 12. At this time, the stirring rod 14 is also in the extended state.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
