Description

Technical Field

[0001] This utility model relates to the field of stirring blade technology, and in particular to a high-efficiency stirring blade for a reaction vessel. Background Technology

[0002] In chemical reactions, reactants need to be in full contact to proceed efficiently. Stirring blades break up the stratification and agglomeration between materials by rotating, so that the components are mixed evenly. Taking the pharmaceutical industry as an example, in drug synthesis reactions, if the stirring is uneven, the local concentration of raw materials will be too high or too low, which will lead to an increase in side reactions, a decrease in product purity, and even the generation of harmful impurities, affecting the safety and efficacy of drugs. Stirring blades can ensure that parameters such as temperature and concentration in the reaction system are uniform and consistent, providing a guarantee for the production of high-quality products.

[0003] In many industrial sectors such as chemical, pharmaceutical, and food processing, reaction vessels are core equipment, and the agitator blades are the "heart" of the reaction vessel. Their crucial role permeates the entire production process, profoundly impacting product quality, production efficiency, and costs. In current practical applications, if the agitator blade height is fixed and the stirring position cannot be adjusted according to material stratification, it becomes impossible to ensure sufficient mixing of the extractant and the extracted material at each height level. This slows down the extraction process, increasing production cycles and costs. Furthermore, when the agitator blades malfunction, the difficulty in installation and disassembly makes maintenance extremely challenging. For example, in chemical production, agitator blades are in constant contact with corrosive materials, making them prone to corrosion damage. If the blades are difficult to disassemble, it may require significant time and effort to find a suitable disassembly method, and may even necessitate damaging parts of the reaction vessel to remove the blades. This not only increases maintenance costs but also prolongs equipment downtime, impacting production progress. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a high-efficiency stirring blade for a reactor, including a connecting column 1 and a mounting column 2. The bottom of the connecting column 1 is fixedly connected to the mounting column 2. The outer side of the mounting column 2 is slidably connected to the mounting ring 3. An adjusting component 4 is provided on the inner side of the mounting ring 3. A first blade 5 is installed on the outer side of the mounting ring 3. The bottom of the mounting column 2 is provided with a mounting component 6. A second blade 7 is installed on the outer side of the mounting component 6.

[0032] The connecting column 1 facilitates the connection between the drive equipment and the mounting column 2. The mounting column 2 assists the mounting ring 3 in sliding. The mounting ring 3 provides a fulcrum for the installation of the first blade 5. The adjusting component 4 facilitates the adjustment of the position of the first blade 5, thereby preventing the blade from being too high and the material from not being fully stirred, resulting in incomplete polymerization. The first blade 5 is arc-shaped, which facilitates the downward pressure on the material, thereby facilitating the uniform mixing of the material with the second blade 7. The mounting component 6 facilitates the installation and removal of the second blade 7.

[0033] The adjustment component 4 includes a limiting frame 41 fixedly connected to the inner wall of the mounting ring 3, and a snap-fit ​​block 42 is slidably connected to the inner wall of the limiting frame 41.

[0034] The limiting frame 41 can assist the locking block 42 in sliding. The locking block 42 can easily limit the mounting ring 3 and prevent it from falling off after the mounting ring 3 is adjusted to the correct position.

[0035] The mounting assembly 6 includes a fixing post 61 that snaps into the inner wall of the mounting post 2. The inner wall of the mounting post 2 is provided with a guide groove 62. A limiting rod 63 for cooperating with the guide groove 62 is fixedly connected to the outer side of the fixing post 61.

[0036] The fixed post 61 can provide a fulcrum for the installation of the second blade 7. The guide groove 62 and the limiting rod 63 can be used together to limit the fixed post 61, thereby facilitating the installation and removal of the fixed post 61, and thus facilitating the installation and removal of the second blade 7.

[0037] Example 2:

[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the inner wall of the fixed column 61 is slidably connected to a limiting frame 8 for limiting the second blade 7, and the outer side of the limiting frame 8 is inserted into the inner wall of the second blade 7.

[0040] The limiting frame 8 can limit the second blade 7, thereby facilitating the separate installation and disassembly of the two limiting frames 8.

[0041] Specifically, the bottom of the fixed column 61 is fixedly connected to the mounting block 9, and the inner wall of the mounting block 9 is rotatably connected to the connecting rod 10.

[0042] The mounting block 9 can assist the connecting rod 10 in rotating. The connecting rod 10 can be easily connected to the mounting rod 11. The connection rod 10 and the mounting rod 11 are designed to prevent the limit bar 12 from jamming the limit frame 8 when it is necessary to release the limit frame 8.

[0043] Specifically, one end of the connecting rod 10 is rotatably connected to the mounting rod 11, and one end of the mounting rod 11 is fixedly connected to the limiting strip 12 for limiting the limiting frame 8.

[0044] The mounting rod 11 and the limiting strip 12 work together to limit the limiting frame 8, thereby facilitating the limiting of the second blade 7, and making it easier to install and remove the second blade 7 when needed.

[0045] Specifically, a connecting block 13 is fixedly connected to the inner wall of the limiting strip 12, and a limiting bolt 14 is threadedly connected to the inner wall of the connecting block 13.

[0046] The combined use of connecting block 13 and limiting bolt 14 facilitates the limiting of the two sets of limiting strips 12, thereby facilitating the limiting frame 8 and improving the stability of the second blade 7 during rotation.

[0047] Specifically, the inner wall of the mounting column 2 is fixedly connected with a first spring 15 for limiting the position of the fixed column 61, and the first spring 15 is located at the top of the fixed column 61.

[0048] The first spring 15 can limit the fixed post 61, thereby preventing it from falling out of the mounting post 2 when the fixed post 61 rotates. The function of the first spring 15 is only to use the spring's rebound force to squeeze the fixed post 61, and it is not fixed to the fixed post 61.

[0049] Specifically, the inner walls of the first blade 5 and the second blade 7 are provided with reserved holes 16 for improving the blade shear force.

[0050] The reserved hole 16 can facilitate the improvement of the mixing effect of the first blade 5 and the second blade 7, and push the fluid in the upper or lower layer to participate in the overall circulation, which greatly enhances the mixing effect of the material in the reactor and reduces the mixing dead zone.

[0051] Specifically, the inner wall of the mounting column 2 is provided with a limiting groove 17 for use with the snap-fit ​​block 42, and the inner wall of the mounting column 2 is fixedly connected with a limiting block 18.

[0052] The use of the limiting groove 17 and the limiting block 18 together can facilitate the limiting of the snap-fit ​​block 42, thereby facilitating the limiting of the mounting ring 3, and further facilitating the adjustment of the height of the mounting ring 3 and the first blade 5.

[0053] Example 3:

[0054] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, a screw 19 is fixedly connected to one end of the first blade 5, and the outer side of the screw 19 is threadedly connected to the inner wall of the mounting ring 3. A limiting nut 20 for limiting the screw 19 is threadedly connected to the outer side of the screw 19.

[0056] The screw 19 and the limiting nut 20 work together to facilitate the individual disassembly of the two sets of first blades 5. At the same time, the screw 19 and the limiting nut 20 work together to facilitate the adjustment of the angle of the first blades 5, thereby improving the flexibility of the first blades 5.

[0057] Specifically, a limiting spring 21 is fixedly connected to the inner wall of the limiting frame 41, one end of the limiting spring 21 is fixedly connected to the outer side of the locking block 42, and a paddle 22 for moving the locking block 42 is fixedly connected to the outer side of the locking block 42.

[0058] The limiting spring 21 can easily limit the locking block 42, and the lever 22 can easily move the locking block 42, thereby facilitating the adjustment of the height of the first blade 5 in conjunction with the limiting groove 17 and the limiting block 18.

[0059] In use, first install the device in the required position, that is, install the top of the connecting column 1 to the output end of the drive equipment. When it is necessary to adjust the position of the first blade 5, first press the lever 22. The lever 22 drives the locking block 42 to move horizontally, disengaging it from the limiting groove 17 and the limiting block 18, and compressing the first spring 15. At this time, the limiting of the mounting ring 3 can be released. Then, the mounting ring 3 can be pulled. When adjusted to the appropriate position, the first spring 15 pushes out the locking block 42, thereby limiting the mounting ring 3 again. At this time, the height adjustment of the mounting ring 3 and the first blade 5 can be completed. When it is necessary to adjust the angle of the first blade 5, the screw 19 can be rotated. When adjusted to the appropriate angle, the limiting nut 20 can be rotated to limit the first blade 5, thereby completing the adjustment of the first blade 5. For adjusting the angle of the first blade 5, when it is necessary to install or remove the first blade 5, first turn the limit nut 20 to release the limit on the first blade 5, and then turn the first blade 5 and the screw 19 until they are completely disengaged from the mounting ring 3. When it is necessary to install or remove the second blade 7, first press the fixing post 61 from bottom to top, and then turn the fixing post 61. At this time, the fixing post 61 will fall off the limit along the guide groove 62, and the fixing post 61 and the second blade 7 can be removed. If it is necessary to replace one of the second blades 7 individually, first turn the limit bolt 14 to release the limit of the limit strip 12 and the limit frame 8. At this time, pull the limit frame 8 to release the limit on the second blade 7, and then pull out the second blade 7 that needs to be replaced. After the replacement is completed, work can be restarted.
