[0002] In many fields such as chemical engineering, pharmaceuticals, and food processing, reaction vessels are commonly used equipment for various chemical reactions. As a key component of the reaction vessel, the performance of the stirring blades directly affects the reaction's effect and efficiency.

[0003] Traditional stirring blades are mostly solid structures. When stirring high-viscosity materials, due to the poor fluidity of the materials, the stirring blades need to overcome a large resistance during rotation, resulting in high power requirements and high energy consumption. At the same time, the fluid interaction between solid stirring blades and materials is limited, making it difficult to fully act on the materials during stirring, leading to uneven mixing and incomplete reaction, which in turn affects product quality and production efficiency. To address this, a stirring impeller with a circular hole for a reactor is proposed. Utility Model Content

[0029] Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: a reaction vessel stirring paddle with round holes, including a vessel body 1, a vessel cover 2 connected to the top of the vessel body 1, a stirring shaft 8 rotatably connected to the center of the vessel cover 2, a plurality of stirring blades 10 provided at the bottom of the stirring shaft 8, and a plurality of round holes 11 opened on the surface of the stirring blades 10, the spacing of the round holes 11 being 10mm-50mm, forming local turbulence during the stirring process. The presence of the round holes 11 increases the fluid interaction between the stirring blades 10 and the material. The structure of the round holes 11 enables high-viscosity materials to generate radial and axial composite flow, reducing stirring resistance. In high-viscosity materials, the stirring blades 10 with round holes 11 reduce the stirring power by about 10%, increase the stirring force, and make the material mix more uniform and the reaction more complete.

[0031] The following is a comparison of mixing data between the stirring blade 10 with and without the round hole 11 in this embodiment:

[0032] Stirring time / minute 60 50 Energy consumption / kWh 100 90 Mixing uniformity / % 85％ 90％

[0033] The data above shows that, in actual use, the stirring blade 10 with the round hole 11 reduces the stirring power by about 10% and shortens the mixing time by about 15%-30%, giving the stirring blade 10 with the round hole 11 an advantage in practical applications.

[0034] A connecting assembly 6 is provided at the bottom of the stirring shaft 8. The connecting assembly 6 is used for disassembling and installing the stirring blade 10. The connecting assembly 6 includes several fixing brackets 61. The inner wall of the fixing bracket 61 is provided with a sliding groove 68. The inner wall of the sliding groove 68 is provided with several limiting grooves 610. A sliding rod 69 is slidably connected to the inner side of the sliding groove 68. A sliding plate 66 is fixed to one side of the sliding rod 69. A locking rod 64 is fixed to one side of the bottom of the sliding plate 66. Several connecting rods 62 are fixed to the top of the stirring blade 10. A locking groove 67 is provided on one side of the connecting rod 62. When the connecting rod 62 at the top of the stirring blade 10 is inserted into the sliding groove 68 of the fixing bracket 61, the outer side of the connecting rod 62 is locked into the limiting groove 610. Pushing the sliding rod 69 compresses the spring 63, so that the locking rod 64 is aligned with the locking groove 67 of the connecting rod 62. When the sliding rod 69 is released, the spring 63 returns to its original position and pushes the sliding plate 66. The locking rod 64 is inserted into the locking groove 67 to complete the locking.

[0035] The locking rod 64 is cylindrical. When the locking rod 64 is inserted into the inner side of the locking groove 67, the stirring blade 10 is in the installed state. When the locking rod 64 leaves the inner side of the locking groove 67, the stirring blade 10 is in the disassembled state. A spring 63 is connected between one of the sliding plates 66 and the inner wall of the sliding groove 68. A cover plate 9 covering the spring 63 is bolted to one side of the fixing frame 61. The first sealing ring prevents material from seeping into and contacting the spring 63.

[0036] A through hole 65 is provided on one side of the slide rod 69. The through hole 65 is used for inserting a tool to push the slide rod 69. A first sealing ring is fixed on one side of the cover plate 9 and fits against one side of the fixing frame 61. The outer side of the connecting rod 62 is adapted to the inner side of the limiting groove 610.

[0037] The inner walls of the locking groove 67 and the sliding groove 68 are both fixed with second sealing rings. The inner side of the second sealing ring is respectively attached to the outer side of the connecting rod 62 and the sliding rod 69, which prevents materials from entering the interior of the relevant components and ensures the normal operation and service life of the equipment.

[0038] The fixing frame 61 is fixed to the bottom of the stirring shaft 8. The top of the lid 2 is provided with a feeding hole 5. The bottom of the body 1 is provided with a discharge pipe 7. A valve is installed on the discharge pipe 7. The discharge pipe 7 at the bottom of the body 1 is used to discharge the material after reaction. The valve installed on the discharge pipe 7 can control the discharge of material. The top of the lid 2 is fixed with a connecting frame 3. The top of the connecting frame 3 is fixed with a motor 4. The output shaft of the motor 4 is connected to the top of the stirring shaft 8 through a coupling. The connecting frame 3 fixed on the top of the lid 2 is used to support the motor 4 and ensure the stable operation of the motor 4.

[0039] Working principle: When materials need to be mixed, the raw materials are added into the inside of the vessel 1 through the feeding hole 5. The motor 4 is started, and its output shaft drives the stirring shaft 8 to rotate at the center of the vessel cover 2 through the coupling. The stirring blades 10 at the bottom of the stirring shaft 8 rotate accordingly, stirring the materials in the vessel 1. Since the surface of the stirring blades 10 has several round holes 11, the presence of the round holes 11 increases the fluid interaction between the stirring blades 10 and the materials. In high-viscosity materials, the stirring power is reduced by about 10%, while the stirring force is increased, making the materials more uniformly mixed and the reaction more complete.

[0040] When the stirring blade 10 needs to be disassembled for maintenance, remove the lid 2 and the stirring shaft 8, use a tool to insert into the through hole 65 on one side of the slide rod 69, push the slide rod 69, the slide rod 69 drives the slide plate 66 to move, thereby causing the locking rod 64 to leave the inside of the locking groove 67. At this time, the stirring blade 10 is in a detachable state, and the stirring blade 10 can be removed from the fixing frame 61.

[0041] When the stirring blade 10 needs to be installed, align the connecting rod 62 at the top of the stirring blade 10 with the limiting groove 610 on the inner wall of the fixing frame 61, insert the connecting rod 62 into the limiting groove 610, push the slide rod 69, and slide the slide rod 69 in the slide groove 68. At the same time, it drives the slide plate 66 to move, and the locking rod 64 at the bottom of the slide plate 66 moves accordingly. When the locking rod 64 is inserted into the locking groove 67 on one side of the connecting rod 62, the stirring blade 10 is in the installation state. At this time, the spring 63 between one of the slide plates 66 and the inner wall of the slide groove 68 is in a compressed state, providing a certain locking force for the locking rod 64 to ensure that the stirring blade 10 is installed firmly.

[0042] A first sealing ring is fixed on one side of the cover plate 9 and fits against the side of the fixed frame 61. This can prevent materials from entering the slide 68 and affecting the movement of components such as the slide rod 69. The spring 63 can be replaced by removing the cover plate 9.

[0043] In summary, raw materials can be conveniently added to the inside of the vessel body 1 through the feeding hole 5. After the motor 4 is started, its output shaft drives the stirring shaft 8 to rotate at the center of the vessel cover 2 through the coupling. The stirring blades 10 at the bottom of the stirring shaft 8 rotate accordingly, which can effectively stir the materials in the vessel body 1. Several round holes 11 are opened on the surface of the stirring blades 10. In high viscosity materials, the stirring power can be reduced by about 10%, which can effectively save energy. The round holes 11 increase the fluid interaction between the stirring blades 10 and the materials, improve the stirring force, and thus make the materials more uniformly mixed, the reaction more complete, and improve the production quality.

[0044] When the stirring blade 10 needs to be disassembled for maintenance, simply insert a tool into the through hole 65 on one side of the slide rod 69, push the slide rod 69, and through a series of linkages, make the locking rod 64 leave the inside of the locking groove 67, so that the stirring blade 10 can be easily removed from the fixing frame 61. The operation is simple and quick. When installing the stirring blade 10, align the connecting rod 62 at the top of the stirring blade 10 with the limiting groove 610 on the inner wall of the fixing frame 61, and then push the slide rod 69 so that the locking rod 64 is inserted into the inside of the locking groove 67 on one side of the connecting rod 62 to complete the installation. The whole process is simple and smooth, and the installation of the stirring blade 10 can be completed quickly, improving the equipment assembly efficiency.
