[0037] like Figure 1 As shown, this embodiment provides a reaction vessel for dispersing materials. The reaction vessel for dispersing materials includes a vessel body 100, a drive assembly 200, a stirring shaft 300, a feed pipe 400, and stirring blades 500.
[0038] like Figure 1 As shown, the vessel body 100 has a stirring chamber 101. A stirring shaft 300 is centrally located within the stirring chamber 101, and stirring blades 500 are mounted on the stirring shaft 300. The driving end of the driving assembly 200 is connected to the stirring shaft 300. The stirring shaft 300 is hollow, forming an inner cavity. Multiple through holes 301 communicating with the inner cavity are provided on the outer surface of the stirring shaft 300. One end of the feed pipe 400 is connected to the outside of the vessel body 100, and the other end is connected to the inner cavity. In this embodiment, the reactor for dispersing materials can accept gas, liquid, or slurry via the feed pipe 400.
[0039] The reactor for dispersing materials provided in this embodiment has a stirring shaft 300 centrally located inside the stirring chamber 101. By providing multiple through holes 301 communicating with the inner cavity on the stirring shaft 300, the material enters the inner cavity of the stirring shaft 300 through the feed pipe 400 and can be dispersed and discharged from the through holes 301 at multiple positions on the outer surface of the stirring shaft 300. Under the drive of the driving assembly 200, the stirring shaft 300, which is centrally located in the stirring chamber 101, rotates, which can promote the rapid and uniform dispersion of the material from the center of the stirring chamber 101 to the surrounding areas, significantly improving the uniformity of the material in the reactor, shortening the time for uniform material distribution, thereby improving the reaction efficiency and reducing the reaction time.
[0040] like Figure 1 As shown, in some embodiments, the vessel body 100 is cylindrical, containing a cylindrical stirring chamber 101. The stirring shaft 300 is coaxially arranged with the cylindrical vessel body 100, thus being centered in the stirring chamber 101. The cylindrical vessel body 100 and the stirring chamber 101 provide a regular and symmetrical space for the material. During rotation, the stirring blades 500 can subject the material to uniform shear force and centrifugal force in the circumferential direction. This helps the material to be mixed more evenly throughout the stirring chamber 101, reducing dead zones and improving stirring efficiency.
[0041] The stirring blades 500 can be elongated and can be connected to the stirring shaft 300 by welding or bolting. Multiple stirring blades 500 can be provided along the length of the stirring shaft 300 to improve the uniformity of stirring in the axial direction of the stirring shaft 300.
[0042] like Figure 1 As shown, optionally, the feed pipe 400 includes an embedded section 401 and a connecting section 402, which are connected by a rotary sealing joint 403. The embedded section 401 is inserted and fixed inside the inner cavity, while the connecting section 402 extends outside the vessel body 100. The connection between the embedded section 401 and the connecting section 402 via the rotary sealing joint 403 ensures a stable connection between the feed pipe 400 and the stirring shaft 300, while also accommodating the rotation of the stirring shaft 300. The rotary sealing joint 403 effectively prevents material leakage at the rotating connection of the feed pipe 400, ensuring the airtightness of the reactor and maintaining the stability of the reaction environment. It also facilitates the installation, disassembly, and maintenance of the feed pipe 400. The embedded section 401 is fixed inside the stirring shaft 300 and rotates with it. The embedded section 401 remains stable relative to the stirring shaft 300, exhibiting high structural reliability and a long service life.
[0043] like Figure 1As shown, optionally, the drive assembly 200 is mounted on the vessel body 100. The drive assembly 200 includes a hollow drive shaft 201 extending from inside the vessel body 100 to outside the vessel body 100. One end of the stirring shaft 300 is connected to the drive shaft 201, and an embedded section 401 is also inserted and fixed inside the drive shaft 201. A rotary sealing joint 403 is located at the end of the drive shaft 201 outside the vessel body 100. This structural design makes the entire feeding and stirring drive system compact. It not only effectively saves space inside and around the reactor, but also ensures efficient power transmission from the drive assembly 200 to the stirring shaft 300, reducing energy loss. Meanwhile, the rotary seal joint 403 is located at the end of the drive shaft 201 that extends outside the vessel body 100, that is, the connection between the connecting section 402 and the embedded section 401 is located at the end of the drive shaft 201 that is outside the vessel body 100. This facilitates daily inspection, maintenance and replacement of the rotary seal connection, ensures reliable sealing performance, reduces the risk of leakage due to sealing problems, and ensures the stability of the reaction environment inside the reactor.
[0044] like Figure 1 As shown, optionally, the drive assembly 200 also includes a coupling 203 with a hollow channel. The two ends of the coupling 203 are connected to the drive shaft 201 and the stirring shaft 300, respectively, with the embedded section 401 passing through the hollow channel. During torque transmission, the coupling 203 further enhances the stability of the connection between the drive shaft 201 and the stirring shaft 300, reducing the possibility of loosening due to shaft misalignment or vibration. The coupling 203 not only ensures the stability of the stirring shaft 300's rotation and extends the equipment's service life, but also provides additional support for the embedded section 401.
[0045] like Figure 1 As shown, in some embodiments, the drive shaft 201, coupling 203, and stirring shaft 300 are connected sequentially from top to bottom and are coaxially arranged. This coaxial arrangement allows the power transmitted by the drive shaft 201 to be directly and smoothly transmitted to the stirring shaft 300 via the coupling 203, avoiding force offset and additional friction caused by misalignment. This top-to-bottom, coaxial arrangement makes the entire drive structure more compact and regular in space, saving space at the top and around the reactor.
[0046] like Figure 1 As shown, optionally, the drive assembly 200 includes a motor body 202 and a drive shaft 201. The motor body 202 is mounted on the vessel body 100, and the drive shaft 201 extends through both ends of the motor body 202 along its length. On one hand, the motor body 202 directly provides power to the drive shaft 201, driving the stirring shaft 300 to rotate and achieve stirring; on the other hand, the drive shaft 201 extends through the motor body 202, facilitating its extension outside the vessel body 100, thereby guiding the feed pipe 400 to extend outside the vessel body 100.
[0047] Optionally, the embedded section 401 is provided with discharge holes corresponding one-to-one with the through holes 301, and the discharge holes are connected to the through holes 301. The discharge holes on the embedded section 401 correspond one-to-one with and are connected to the through holes 301 of the stirring shaft 300, ensuring that the material discharge path from the feed pipe 400 to the outer surface of the stirring shaft 300 is accurate. This helps to optimize the initial distribution state of the material in the reactor, thereby improving the mixing uniformity of the material with other substances in the reactor, improving reaction efficiency and reaction quality, and making the reaction process more controllable.
[0048] Optionally, the opening of the through hole 301 forms an angle with the length direction of the stirring blade 500. When the stirring shaft 300 rotates, the stirring blade 500 pushes the existing material in the reactor in a circular motion, while newly added material discharged from the stirring shaft 300 at different angles interacts with the existing material driven by the stirring blade 500. This special angle design allows for more thorough mixing of the newly added and existing materials, improving the uniformity of the mixture, thereby effectively increasing reaction efficiency and promoting a more complete reaction.
[0049] In some embodiments, the opening of the through hole 301 is oriented at an angle of 30-60° with the length direction of the stirring blade 500, which ensures rapid dispersion of the new material and improves the mixing effect between the new material and the existing material.
[0050] In some embodiments, the stirring blade 500 is perpendicularly connected to the stirring shaft 300, and the opening orientation of the through hole 301 is inclined relative to the longitudinal direction of the stirring shaft 300. In other embodiments, the opening orientation of the through hole 301 is along the radial direction of the stirring shaft 300, while the stirring blade 500 is inclined relative to the stirring shaft 300.
[0051] Optionally, a filter screen is provided at each through-hole 301. The mesh size of the filter screen is smaller than the particle size of the material in the reactor and larger than the particle size of the material in the inlet pipe, thereby preventing the material in the reactor from flowing back into the stirring shaft 300. In some embodiments, the new material provided by the feed pipe 400 is gas, and the existing material in the reactor is slurry.
[0052] Optionally, multiple through holes 301 are spaced apart and evenly distributed along the length of the stirring shaft 300. The multiple through holes 301 spaced apart and evenly distributed along the length of the stirring shaft 300 can ensure that the material is discharged evenly in the axial direction of the stirring shaft 300, ensuring that the material at different heights in the reactor can contact the material discharged from the through holes 301 in a timely and equal manner.
[0053] Optionally, the through holes 301 are spaced apart and symmetrically distributed along the circumferential direction of the stirring shaft 300. The spaced apart and symmetrically distributed through holes 301 along the circumferential direction of the stirring shaft 300 ensures that the material is uniformly diffused in the circumferential direction of the reactor.
[0054] Optionally, the through-hole 301 can be circular, elliptical, or slit-shaped. A circular through-hole 301 has a simple structure, resulting in relatively uniform and stable material flow, which is beneficial for improving diffusion uniformity. An elliptical through-hole 301 can enhance the diffusion effect of materials or gases along the major axis of the ellipse, making it suitable for reactions requiring enhanced material distribution in a specific direction. A slit-shaped through-hole 301 allows materials to be concentrated and discharged in a certain area, making it suitable for reactions with special requirements for material or gas distribution. The reactor can flexibly select the appropriate shape of the through-hole 301 according to different reaction processes, material characteristics, and specific needs during the reaction process to achieve the best material or gas distribution effect, improving the versatility and adaptability of the reactor and meeting various complex production and experimental needs. In other embodiments, the through-hole 301 can also be irregular, triangular, or rectangular, etc.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
