Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically to a pharmaceutical reaction vessel with improved stirring efficiency. Background Technology
[0002] A reaction vessel is a device that uses heating, condensation, stirring, or other methods to induce physical or chemical reactions in materials. Most of these are sealed devices and are commonly used in industries such as chemical, petroleum, and medical. Existing reaction vessels mainly consist of a tank body, a sealing cover, and a stirring device. There are many types of stirring devices, which are driven by motors to stir, mix, blend, and homogenize materials.
[0003] For example, Chinese utility model patent application number 202421826922.3 discloses a reaction vessel for improving stirring uniformity. This utility model sets several baffles on the side wall of the inner cavity of the reaction vessel body, and the baffles are connected to the inner cavity wall of the reaction vessel body through a rotating shaft. At the same time, the rotation angle of the baffles can be adjusted by a connecting rod, and the position of the baffles is limited and fixed by a limiting block. Thus, when the reaction vessel is working, the material tumbles when it encounters resistance at each baffle position, so that multiple tumbling vortices are formed in the entire reaction vessel, and the material converges with the vortex of the stirring paddle, which greatly improves the material dispersion efficiency of the entire reaction vessel. By setting a secondary stirring blade on the side of the main stirring blade, and installing an inclined first dispersion blade and a second dispersion blade at the bottom of the drive shaft, when the drive motor drives the drive shaft to rotate, the main stirring blade, the secondary stirring blade, the first dispersion blade and the second dispersion blade will stir the material at multiple angles, which improves the material dispersion efficiency.
[0004] Although the device in the aforementioned patent can stir materials from multiple angles, in actual use, some materials in the area near the inner wall of the reactor cannot be fully stirred, which not only easily causes stratification, but also reduces the overall mixing effect and overall mixing efficiency.

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 Figure 1-4 In this embodiment of the present invention, a pharmaceutical reaction vessel for improving stirring efficiency includes a reaction vessel body 1. A feed pipe 10 is fixedly connected to the bottom of the reaction vessel body 1, and a solenoid valve 11 is installed on the feed pipe 10. An annular groove 2 is formed at the top of the reaction vessel body 1. An annular plate 3 is rotatably connected inside the annular groove 2. A hollow shaft 4 is rotatably connected to the top of the annular plate 3. The bottom end of the hollow shaft 4 rotatably passes through the annular plate 3 and extends into the interior of the reaction vessel body 1. Several rotating rods 5 are rotatably connected to the hollow shaft 4, arranged in a circumferential array. One end of each rotating rod 5 is sealed and extends rotatably into the interior of the hollow shaft 4. Two stirring plates 6 are fixedly connected to the outer surfaces of each rotating rod 5. Several connecting shafts 7 are rotatably connected to the annular plate 3, and their outer surfaces are fixedly connected to... The reactor body 1 is equipped with several spiral blades 8 and stirring plates 9. A connecting assembly and a driving assembly are installed on the top of the reactor body 1. A rotating assembly is installed inside the hollow shaft 4. Through the arrangement of the reactor body 1, hollow shaft 4, rotating rod 5, connecting shaft 7, spiral blades 8, stirring plates 9, gear 12 and bevel gear 19, the raw materials of medicinal materials at the center of the reactor body 1 can be horizontally and vertically stirred and mixed. At the same time, the raw materials of medicinal materials near the inner wall can be horizontally and vertically conveyed and stirred in the opposite direction. This allows the raw materials of medicinal materials on the inner wall of the reactor body 1 to be fully mixed as a whole. This not only ensures that the raw materials of medicinal materials on the inner wall are fully and effectively stirred, but also continuously lifts the raw materials vertically and vertically during the mixing process to prevent stratification, thereby improving the overall mixing efficiency and effect of the raw materials of medicinal materials.
[0031] The connecting assembly includes several gears 12 and a gear ring 13. The gears 12 are fixedly connected to the top of several connecting shafts 7, and the gear ring 13 is fixedly connected to the top of the reactor body 1. The gears 12 mesh with the gear ring 13. By setting the connecting assembly, the several connecting shafts 7 and the stirring plate 9 can rotate synchronously to mix and stir the medicinal materials on the inner wall of the reactor body 1, thereby improving the overall mixing efficiency.
[0032] The drive assembly includes a motor 14, which is located on the top of the reactor body 1. A transmission mechanism 15 is connected between the output end of the motor 14 and the outer surface of the hollow shaft 4. A bracket 16 is fixedly connected to the top of the reactor body 1, and the motor 14 is fixedly installed on the top of the bracket 16. Through the configuration of the drive assembly, the hollow shaft 4 can be driven to rotate, thereby driving several stirring plates 6 to rotate, so as to carry out the stirring and mixing of medicinal materials.
[0033] The rotating assembly includes a fixed rod 17 and several bevel gears 18. The fixed rod 17 is located inside the hollow shaft 4, and several bevel gears 19 are fixedly sleeved on the outer surface of the fixed rod 17. The several bevel gears 18 are respectively fixedly connected to one end of several rotating rods 5. The top end of the fixed rod 17 is fixedly connected to the bottom of the bracket 16. The several bevel gears 18 are all located inside the hollow shaft 4. By setting up the rotating assembly, the several stirring plates 6 can rotate up and down during the horizontal rotation, thereby improving the mixing efficiency and effect of the medicinal materials in the center of the reactor body 1.
[0034] The working principle of this utility model is as follows: When in use, an appropriate amount of medicinal materials to be mixed is added into the reactor body 1 through the feed port of the reactor body 1. Then, the motor 14 is started to make its output end rotate. Under the transmission action of the transmission structure, the hollow shaft 4, several rotating rods 5 and several stirring plates 6 rotate synchronously. During the rotation, the bevel gear 18 rotates synchronously horizontally. Under the action of the corresponding meshing and fixedly set bevel gear 19, the bevel gear 18 rotates up and down, and drives the corresponding rotating rods 5 and stirring plates 6 to rotate up and down, so that the medicinal materials can be stirred horizontally and vertically, improving the mixing efficiency.
[0035] When the starting motor 14 drives the hollow shaft 4 to rotate, the hollow shaft 4 synchronously drives the annular plate 3 to rotate. The annular plate 3 drives several connecting shafts 7, gears 12, spiral blades 8 and stirring plates 9 to rotate synchronously. The gears 12 rotate under the drive of the meshing gear ring 13, and drive the corresponding connecting shafts 7, spiral blades 8 and stirring plates 9 to rotate. This can stir the medicinal materials on the inner wall of the reactor body 1 and make them continuously transported up and down for mixing. At the same time, in conjunction with the rotating stirring plate 6, the medicinal materials in the center and inner wall of the reactor body 1 can be fully mixed, improving the mixing effect.
[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
