[0025] Specifically, the output shaft of the motor 21 is connected with one end of the stirring shaft 25 through the elastic coupling, the elastic coupling has certain elasticity and shock absorption capacity, can compensate the slight deviation and vibration between the two shafts, and ensures the stable transmission of power. The stirring shaft 25 passes through the bearing seat 22 and is connected with the bearing seat 22 through the deep groove ball bearing, in the embodiment, the deep groove ball bearing is not used for directly supporting the stirring rod 3, but is used for supporting the stirring shaft 25, and the load and stability requirements of the deep groove ball bearing are relatively low. The other end of the stirring shaft 25 is connected with the stirring rod 3 through the flange, and the indirect transmission of power is realized. The stirring rod 3 is connected between the sealing seat 24 through the cylindrical roller bearing 33, the cylindrical roller bearing 33 has a large contact area and good stability, and can effectively reduce the jumping and swinging of the stirring rod 3 in the use process. In addition, the housing of the motor 21 is connected and relatively fixed between the sealing seat 24 through the bearing seat 22 and the transmission seat 23, the transmission stability and reliability of the transmission path of the output shaft-stirring shaft 25-stirring rod 3 of the motor 21 can be further improved. At the same time, the mechanical seal is arranged between the sealing seat 24 and the stirring rod 3, the sealing property of the reaction kettle body 1 is ensured, and the leakage of the reactant is prevented.

[0026] In this embodiment, the cylindrical roller bearing 33 is used to replace the traditional deep groove ball bearing to support the stirring rod 3, which increases the area of the support contact, improves the stability and supportability of the stirring system, and reduces the jumping and swinging of the stirring rod 3 during use. The motor 21 is connected with the stirring rod 3 through the stirring shaft 25, and the stirring shaft 25 is connected with the bearing seat 22 through the deep groove ball bearing, which has good transmission stability and supportability, and can further inhibit the jumping and swinging of the stirring rod 3 during use.

In summary, the embodiment can improve the stirring effect and the working efficiency of the reaction kettle. In addition, the mechanical seal ensures the sealing of the reaction kettle body 1, effectively prevents the leakage of the reactants, and ensures the safety and accuracy of the experiment.

[0027] Optionally, as shown in Figure 2 The stirring blade 31 is provided with a plurality of fluid grooves 32 extending through the stirring blade 31 from top to bottom.

[0028] Specifically, the stirring blade 31 is provided with a plurality of fluid grooves 32 extending along the longitudinal direction of the stirring blade 31 and through the entire stirring blade 31 from top to bottom. The number, shape and size of the fluid grooves 32 can be customized according to the specific experimental requirements and the characteristics of the reactants.

[0029] In this optional embodiment, when the stirring part 2 works, the motor 21 drives the stirring rod 3 to rotate, and then drives the stirring blade 31 to stir in the reaction kettle body 1. The design of the fluid grooves 32 on the stirring blade 31 makes the reactants flow and mix better along the fluid grooves 32 during stirring. The existence of the fluid grooves 32 increases the contact area between the stirring blade 31 and the reactants, and the gas generated during stirring can flow along the fluid grooves 32 to form a regular gas channel, reducing the resistance to the stirring blade 31.

[0030] Optionally, as shown in Figure 2 The fluid grooves 32 are curved.

[0031] Specifically, when the stirring component 2 is in operation, the motor 21 drives the stirring shaft 25 to rotate, and the stirring blade 31 is stirred in the reactor body 1 accordingly. Since the fluid groove 32 is designed in a curved shape, not only the contact area of the stirring blade 31 with the reactants is increased, but more importantly, the flow path of the reactants during stirring is changed. The curved fluid groove 32 can guide the reactants to flow along a more complex and variable path, thereby improving the uniformity and efficiency of stirring. In addition, the curved fluid groove 32 can also generate a certain turbulent effect, further enhancing the mixing effect of the reactants.

[0032] In this optional embodiment, the curved fluid groove 32 enables the reactants to flow along a more complex and variable path during stirring, thereby improving the uniformity of stirring. The turbulent effect that the curved fluid groove 32 can generate can further enhance the mixing effect of the reactants, which can break the interface between the reactants and promote diffusion and mixing between different components. The curved fluid groove 32 also helps to optimize the hydrodynamic performance of the stirring blade 31, reducing energy consumption and noise during stirring.

[0033] Optionally, the stirring blade 31 is made of Teflon plate.

[0034] Specifically, Teflon plate has excellent corrosion resistance and high-temperature resistance. When the stirring component 2 is in operation, the motor 21 drives the stirring rod 3 to rotate, and the stirring blade 31 made of Teflon plate is stirred in the reactor body 1 accordingly. Since Teflon plate has good chemical stability, it will not react with most chemicals, thereby ensuring the purity and safety of the stirring process. In addition, Teflon plate also has a low coefficient of friction, which helps to reduce energy consumption and wear during stirring.

[0035] In this optional embodiment, the stirring blade 31 made of Teflon plate can resist corrosion from most chemicals, while having excellent high-temperature resistance, making the reactor suitable for a wider range of experimental conditions. Since Teflon plate does not react with most chemicals, it will not contaminate the reactants, thereby ensuring the purity and safety of the stirring process. Teflon plate has a low coefficient of friction, which helps to reduce energy consumption and wear of the stirring blade 31 during stirring, prolonging the service life of the equipment.

[0036] Optionally, the motor 21 is a magnetic motor 21, and the elastic coupling is a magnetic sleeve.

[0037] Specifically, the magnetic motor 21 transmits torque through magnetic coupling without direct physical contact, thereby achieving leak-free driving. When the magnetic motor 21 starts, the permanent magnet inside generates a magnetic field, which is transmitted through the air gap to the magnetic sleeve (as an elastic coupling), thereby driving the stirring shaft 25 and the stirring rod 3 to rotate. The magnetic sleeve as an elastic coupling not only serves as a connection and torque transmission, but also has a certain elasticity, which can absorb and buffer the vibration and impact generated during stirring.

[0038] In this optional embodiment, the magnetic motor 21 transmits torque through magnetic coupling without the need for sealing devices such as shaft seals, thereby avoiding leakage problems, especially for reaction kettles with high sealing requirements. Due to the non-contact design of the magnetic motor 21 and the magnetic sleeve, safety accidents such as fire, explosion or environmental pollution caused by shaft seal leakage are avoided. The magnetic motor 21 has stable output torque and a high speed range, which can meet different stirring requirements and improve stirring efficiency.

[0039] Optionally, the deep groove ball bearing is a double-row deep groove ball bearing.

[0040] Specifically, the double-row deep groove ball bearing is a rolling bearing with two rows of raceways on the inner and outer rings, each row of raceways has a row of steel balls, and the two rows of steel balls have certain load-carrying capacity in the radial and axial directions. When the motor 21 output shaft rotates, the stirring shaft 25 is driven to rotate through the inner ring of the bearing, and the steel balls roll between the inner and outer ring raceways, thereby realizing torque transmission and rotation support. Since the double-row deep groove ball bearing has double rows of steel balls, it has stronger load-carrying capacity and can withstand greater radial and axial loads, which provides better support and stability for various forces and moments that the stirring shaft 25 may be subjected to during stirring.

[0041] In this optional embodiment, the double-row deep groove ball bearing has higher load-carrying capacity than the single-row deep groove ball bearing, which can better support various forces and moments that the stirring shaft 25 may be subjected to during stirring, ensuring stable operation of the stirring shaft 25. Due to the structural characteristics of the double-row deep groove ball bearing, it can better resist vibration and impact generated during stirring, thereby improving the overall stability of the stirring system. Stable bearing support can ensure smooth operation of the stirring shaft 25, reduce energy loss caused by vibration and impact, and improve stirring efficiency.

[0042] Optionally, the cylindrical roller bearing 33 is a self-aligning roller bearing.

[0043] Specifically, when the stirring rod 3 rotates under the drive of the motor 21, the inner ring of the self-aligning roller bearing is tightly connected with the stirring rod 3, and the outer ring is connected with the bearing seat 22 or the related support structure. Due to the spherical roller design of the self-aligning roller bearing, it can adapt to the slight eccentricity and deflection that may occur during the rotation of the stirring rod 3, thereby ensuring the stable rotation of the stirring rod 3. In addition, the double-row roller structure of the self-aligning roller bearing also enables it to withstand greater radial load and certain axial load.

[0044] In this optional embodiment, the spherical rollers of the self-aligning roller bearing enable it to adapt to the slight eccentricity and deflection of the stirring shaft 25, thereby improving the rotation stability of the stirring rod 3 and reducing the vibration and noise caused by the misalignment of the shaft. The double-row roller structure of the self-aligning roller bearing enables it to withstand greater radial load and certain axial load, providing better support for the large load that may occur during the stirring process.

[0045] Optionally, a discharge port is provided at the bottom of the reaction kettle body 1, and a valve is provided at the discharge port.

[0046] Specifically, after the materials in the reaction kettle undergo stirring, reaction, and other processes, they need to be discharged in some way for subsequent treatment or collection. At this time, the valve provided at the discharge port is opened, and the materials in the reaction kettle can flow out under the action of gravity or through other auxiliary means (such as pumping). The discharge port is provided at the bottom of the reaction kettle body 1 to ensure that the materials can be discharged to the maximum extent and avoid residue. The valve controls the flow of materials and can be opened or closed as needed to achieve precise control of material discharge.

[0047] In this optional embodiment, the discharge port is provided at the bottom of the reaction kettle body 1, which can ensure that the materials can fully utilize the action of gravity when discharged, thereby improving the discharge efficiency. Discharging from the bottom helps to reduce the residue of materials in the reaction kettle, improve the utilization rate of materials, and reduce the workload of cleaning and maintenance.

[0048] Optionally, a heating jacket is provided outside the reaction kettle body 1, and a heating medium channel is provided in the heating jacket for heating the materials in the reaction kettle body 1.

[0049] Specifically, the heating jacket closely fits the outside of the reaction kettle body 1, forming a sealed heating space. The heating medium channel is provided in this heating space and is usually designed in a spiral shape or other shapes that can increase the heat exchange area to improve the heating efficiency. When the heating medium flows in the channel, it exchanges heat with the reaction kettle body 1, transferring heat to the reaction kettle body 1 and causing it to warm up. The reaction kettle body 1 then transfers heat to the materials inside it, thereby achieving the heating of the materials.

[0050] In the optional embodiment, the heating jacket and the heating medium channel enable heat to be uniformly and rapidly transferred to the reactor body 1 and the material, thereby improving the heating efficiency. By adjusting the flow rate, temperature and heating time of the heating medium and other parameters, the temperature of the reactor body 1 and the material can be accurately controlled to meet different process requirements.

[0051] Optionally, the reactor body 1 is further provided with a visual window and a sampling port.

[0052] Specifically, the visual window enables the operator to directly observe the reaction state and changes of the material inside the reactor, and the visual window also provides more intuitive experimental data for the researchers, which helps them better understand the reaction process and product properties. The sampling port facilitates the operator to take out samples from the reactor for detection and analysis. Through the sampling port, the operator can conveniently obtain the material samples in the reaction process for subsequent laboratory analysis.

[0053] In the optional embodiment, the visual window and the sampling port enable the operator to more conveniently observe the reaction and take samples, thereby reducing the trouble of opening the reactor cover or disassembling other components.

[0054] Although the present application is disclosed as above, the protection scope of the present application is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications shall fall within the protection scope of the present application.
