[0001] This utility model relates to the field of chemical equipment technology, specifically to a reaction vessel. Background Technology

[0002] In many industrial production fields such as chemical, pharmaceutical, and food industries, reaction vessels are the core equipment for material reactions.

[0003] The existing reactor stirring components have a relatively simple design, with a single layer of stirring paddles, which leads to insufficient material exchange. In addition, the blades of the stirring paddles are usually installed at a uniform angle, resulting in dead zones and uneven material mixing. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a reaction vessel, the specific solution of which is as follows:

[0005] A reaction vessel, the reaction vessel comprising: The vessel body has a sealed reaction chamber inside for containing materials to react; the vessel body has at least one inlet and at least one outlet, both of which are connected to the reaction chamber. The stirring assembly is located inside the reaction chamber; Driver components; The stirring assembly includes a stirring shaft and multiple layers of stirring blades; one end of the stirring shaft is driven to the output shaft of the driving assembly, and the other end extends into the reaction chamber; the multiple layers of stirring blades are disposed at the end of the stirring shaft that extends into the reaction chamber, and are evenly distributed at intervals along the axial direction of the stirring shaft; each layer of stirring blades includes multiple stirring blades, and the multiple stirring blades of the same layer of stirring blades are distributed circumferentially along the stirring shaft and have different angles; The stirring shaft rotates around the axial direction of the vessel body under the drive of the drive assembly, thereby driving the multiple stirring paddles to rotate and stir the materials in the reaction chamber.

[0006] In an optional embodiment, the stirring shaft is provided with a plurality of mounting slots, and the end of the stirring blade is provided with a mounting block that matches the mounting slot, and the mounting block is detachably connected to the mounting slot.

[0007] In an optional embodiment, the distance between the bottommost stirring paddle and the inner bottom wall of the reaction chamber is 1 / 10 to 1 / 8 of the height of the vessel. In an optional embodiment, the plurality of stirring blades are evenly distributed along the circumference of the stirring shaft; the distance between two adjacent stirring blades is 0.5-2.5 times the diameter of the stirring shaft.

[0008] In an optional embodiment, the included angle between each of the stirring blades and the axis of the stirring shaft ranges from 30° to 60°.

[0009] In an optional embodiment, the outer surface of the stirring shaft and / or the outer surface of the stirring blades are both covered with a wear-resistant and corrosion-resistant coating.

[0010] In an optional embodiment, the reaction vessel further includes: A control component, comprising a speed adjustment module and / or a steering adjustment module, wherein the speed adjustment module and / or the steering adjustment module are electrically connected to the drive component and are used to adjust the rotational speed of the drive component and / or control the steering direction of the drive component, thereby controlling the stirring speed and / or stirring direction of the stirring component. In an optional embodiment, the reaction vessel further includes: A filter assembly is located in the region corresponding to the outlet within the reaction chamber.

[0011] In an optional embodiment, a control valve for controlling the flow rate is provided at the feed inlet and / or the discharge outlet; A sealing element is provided at the connection between the vessel body and the vessel lid, and / or at the feed inlet, and / or at the discharge outlet.

[0012] Beneficial effects: This application arranges multiple layers of stirring blades at uniform intervals along the axial direction of the stirring shaft. Each layer of stirring blades can generate an independent radial flow field. The flow fields of adjacent layers are superimposed on each other, forming multiple shear zones in the axial direction of the reactor. This allows the materials to achieve more complete exchange in the reactor and avoids uneven mixing caused by material stratification. By installing multiple stirring blades of the same layer of stirring blades along the circumference and at different angles, the materials can be subjected to multi-directional shear forces during the stirring process, thereby avoiding the stirring dead angle caused by the uniform angle installation of the blades and improving the stirring effect.

[0024] Example 1 As per the instruction manual Figure 1 As shown, the reaction vessel provided in this embodiment includes: The vessel body 1 has a sealed reaction chamber 12 inside, which is used to contain materials for reaction; the vessel body 1 is provided with at least one inlet 13 and at least one outlet 14, and the inlet 13 and the outlet 14 are both connected to the reaction chamber 12. The stirring assembly 2 is located inside the reaction chamber 12; The driving component 3 is connected to the stirring component 2 and is used to drive the stirring component 2 to rotate so as to stir the material in the reaction chamber 12.

[0025] In an optional embodiment, the reactor body 1 can be made of a high-strength, corrosion-resistant material, such as 316L stainless steel. 316L stainless steel possesses corrosion resistance and high strength, making it suitable for highly corrosive reaction environments such as chemical and pharmaceutical industries. This effectively extends the service life of the reactor and reduces equipment maintenance costs. The reactor body 1 forms a sealed reaction chamber 12. Specifically, the chamber wall can be made with a smooth surface. A smooth chamber wall reduces frictional resistance between the material and the chamber wall, allowing for smoother material flow during the reaction and preventing incomplete localized reactions due to poor material flow. Furthermore, it effectively reduces the possibility of material residue, minimizing material waste, and facilitates cleaning of the reactor after the reaction.

[0026] For further details, please refer to [link / reference]. Figure 1-3As shown, the stirring assembly 2 includes a stirring shaft 20 and multiple layers of stirring paddles 22. One end of the stirring shaft 20 is driven and connected to the output shaft of the drive assembly 2, and the other end extends into the reaction chamber 12. The multiple layers of stirring paddles 22 are disposed at the end of the stirring shaft 20 that extends into the reaction chamber 12, and are evenly distributed at intervals along the axial direction of the stirring shaft 20. Each layer of stirring paddles 22 includes multiple stirring blades 21, and the multiple stirring blades 21 of the same layer of stirring paddles 22 are distributed circumferentially along the stirring shaft 20 and have different angles. Under the drive of the drive assembly 3, the stirring shaft 20 rotates around the axial direction of the vessel body 1, thereby driving the multiple stirring paddles 22 to rotate and stir the material in the reaction chamber 12.

[0027] The stirring shaft 20 and multiple stirring paddles 22 can simultaneously stir in different directions, enhancing the mixing effect between materials and improving the uniformity of material mixing. The multiple stirring paddles 22 can cover a wider area, effectively avoiding dead zones in the mixing process. Furthermore, the parallel operation of multiple stirring paddles 22 can accelerate the mixing speed, shorten the mixing time, and improve production efficiency. In an optional embodiment, the stirring shaft 20 is made of a high-strength metal material (e.g., stainless steel) to ensure sufficient strength and stability during operation. The surface of the stirring shaft 20 can be processed to reduce frictional resistance with the materials, while also facilitating cleaning and maintenance. The stirring shaft 20 can also be designed as a hollow shaft, allowing the introduction of coolant or heating fluid to cool or heat the shaft body, adapting to diverse reaction requirements.

[0028] In one alternative embodiment, the number of stirring blades 21 can be two, three, four, or more. The stirring blades 21 are typically made of corrosion-resistant metal or composite materials, and their shapes can be inclined blades, folded paddle blades, or anchor blades. Inclined blades generate axial and radial mixing flows, accelerating the up-and-down circulation of materials. Folded paddle blades enhance shear force, suitable for dispersing high-viscosity materials. Anchor blades are close to the vessel wall, preventing material deposition on the vessel wall. This combined design significantly improves the mixing uniformity and reaction efficiency of the materials, and the reaction time can be greatly shortened compared to the traditional single-blade structure. The stirring blades 21 can be fixed to the stirring shaft by welding or bolting.

[0029] In an optional embodiment, one end of the stirring shaft 20 can be driven to the output shaft of the drive assembly 3 via a coupling. The drive assembly 3 may include a servo motor and a speed transmission device. The servo motor may be an AC permanent magnet synchronous servo motor, and the speed transmission device may be a gear transmission device or a planetary gear transmission device. A motor base can be installed on the top of the reactor, and the servo motor is fixed to the motor base with bolts, ensuring that the axis of the servo motor is coaxial with the axis of the stirring shaft 20 to reduce eccentric loads during operation and extend the service life of the equipment. One half of the coupling is fitted onto the output shaft of the servo motor, and the other half of the coupling is inserted into one end of the stirring shaft 20. The coupling may be a diaphragm coupling or a swivel coupling.

[0030] During the reaction, materials may stratify within the reaction chamber due to gravity. By uniformly distributing multiple stirring paddles 22 along the axial direction, this stratification can be effectively eliminated, ensuring consistent material concentration, temperature, and other parameters throughout the reaction chamber, thus improving the stability and controllability of the reaction. For example, in some continuous reaction processes, uniform stirring can guarantee consistent residence time of reactants within the reaction chamber, resulting in more stable product quality.

[0031] In an optional embodiment, the distance between the bottommost stirring paddle 22 and the inner bottom wall of the reaction chamber 12 is 1 / 10 to 1 / 8 of the height of the vessel body 1.

[0032] Due to the flow characteristics of the materials inside the reactor and the stirring requirements, the distance between the stirring paddle and the bottom wall of the reaction chamber is set to 1 / 10 of the reactor height. This distance ensures thorough stirring of the materials at the bottom, preventing material accumulation and improving the stirring effect. It also prevents the stirring paddle 22 from colliding with the bottom wall of the reaction chamber 12 during rotation, extending the service life of both the stirring paddle 22 and the reactor 1. Due to the mass and heat transfer efficiency requirements during stirring, the distance between the stirring paddle and the bottom wall of the reaction chamber is set to 1 / 8 of the reactor height. This distance allows for a more ideal fluid circulation, resulting in a more uniform distribution of heat and reactants within the reactor, thus improving mass and heat transfer efficiency.

[0033] See Figure 3 In one optional embodiment, the stirring shaft 20 is provided with a plurality of mounting grooves 200 along the axial and / or radial direction, and the end of the stirring blade 21 is provided with a mounting block 210 that matches the mounting groove 200, and the mounting block 210 is detachably connected to the mounting groove 200.

[0034] In an alternative embodiment, the mounting groove 200 can be in the shape of a dovetail groove, which provides better connection stability and shear resistance. The end of the stirring blade 21 is provided with a dovetail-shaped mounting block 210 that matches the dovetail groove.

[0035] Furthermore, the mounting block 210 and the mounting groove 200 can be detachably connected using high-strength bolts. During installation, the mounting block 210 is inserted into the mounting groove 200 and then secured with bolts or other fasteners. When it is necessary to replace the stirring blade 21, simply loosen the bolts, remove the old stirring blade 21, and then install the new stirring blade 21. This simple and quick process greatly improves the maintenance efficiency of the equipment.

[0036] The detachable connection between the mounting block 210 and the mounting groove 200 enables a detachable connection between the stirring shaft 20 and the stirring blades 21. This detachable connection facilitates the installation and replacement of the stirring blades 21. When the stirring blades 21 are worn or damaged, the old blades can be easily removed and replaced with new ones without replacing the entire stirring shaft 20, reducing maintenance costs and time. Furthermore, the detachable connection allows for flexible adjustment of the number and position of the stirring blades 21 according to different reaction requirements. For example, in reactions requiring different stirring intensities, the stirring effect can be altered by increasing or decreasing the number of stirring blades 21.

[0037] In an optional embodiment, each of the stirring blades 21 is uniformly distributed circumferentially along the stirring shaft 20.

[0038] During actual mixing, the stirring blades 21 are evenly distributed around the stirring shaft 20, causing the material to flow uniformly within the reaction chamber. The evenly distributed stirring blades 21 ensure that the mixing force is evenly distributed in the circumferential direction, avoiding dead zones. During mixing, the material flows regularly under the action of the stirring blades 21, thereby improving mixing efficiency.

[0039] Furthermore, the distance between two adjacent stirring blades 21 is 0.5-2.5 times the diameter of the stirring shaft 20.

[0040] When the spacing between the stirring blades 21 is less than 0.5 times the diameter of the stirring shaft, the space between the blades is too small, which restricts the flow of material between the blades, worsens the shearing and mixing effect, and significantly reduces the mixing efficiency. Furthermore, the small blade spacing increases mutual interference between the blades during mixing, leading to increased mixing resistance and affecting the mixing effect. When the spacing between the stirring blades is greater than 2.5 times the diameter of the stirring shaft, the space between the blades is too large, lengthening the flow path of the material between the blades, resulting in poor mixing uniformity and making it difficult to achieve rapid and uniform mixing. In addition, the large blade spacing weakens the pushing effect of the stirring blades on the material, reducing the axial and radial flow velocity of the material, thus decreasing the mixing efficiency.

[0041] In an optional embodiment, the included angle between each of the stirring blades 21 and the axis of the stirring shaft 20 is in the range of 30°-60°.

[0042] The stirring blade 21 forms an angle with the axis of the stirring shaft 20, allowing the stirring blade 21 to generate a suitable stirring force during rotation. This effectively promotes material flow without generating excessive resistance. An angle that is too small may result in insufficient pushing force from the stirring blade 21, failing to fully mix the materials; an angle that is too large may increase energy consumption during stirring and may cause excessively vigorous material flow, affecting reaction stability. For example, the angle between the stirring blade 21 and the axis of the stirring shaft 20 is set to 45°. During stirring, the stirring blade 21 rotates at a 45° angle, generating a moderate stirring force that ensures stable material flow within the reaction chamber, thereby improving reaction selectivity and yield.

[0043] Furthermore, as per the instruction manual... Figure 1 Included with instruction manual Figure 4 As shown, the vessel body 1 includes a vessel body 10 and a vessel lid 11.

[0044] The vessel body 10 has a hollow cylindrical structure and is the main part of the reactor. The internal space of the vessel body 10 forms the reaction chamber 12, which is used to contain materials for reaction. The vessel lid 11 is fitted onto the top of the vessel body 10, and the two fit tightly together to completely seal the reaction chamber 12, preventing material leakage or the entry of external impurities during the reaction. The vessel body 10 can be made of a high-strength, corrosion-resistant metal material (e.g., 316L stainless steel), and the vessel lid 11 can be made of the same or compatible material as the vessel body 10 to ensure overall strength and corrosion resistance.

[0045] In this embodiment, the stirring shaft 20 penetrates the vessel cover 11 and is vertically positioned within the reaction chamber 12. The penetrating end of the stirring shaft 20 is driven to connect with the output shaft of the drive assembly 3, and rotates around the axial direction of the vessel body 1 under the drive of the drive assembly 3.

[0046] Furthermore, in an optional embodiment, the vessel body 10 and the vessel lid 11 are detachably connected, for example, via a flange connection with a sealing gasket. This ensures the sealing of the reaction chamber 12 while facilitating disassembly. During material feeding, the vessel lid 11 can be easily opened, providing ample operating space whether materials are added manually or using automated feeding equipment. This effectively prevents material spillage and improves feeding efficiency and accuracy. During equipment inspection, maintenance, and cleaning of the reaction chamber 12, personnel can remove the vessel lid 11 to inspect and clean the interior of the vessel body 10, improving maintenance efficiency. In addition, the modular structure provides convenience when replacing stirring components of different specifications or upgrading the internal structure of the reaction vessel, reducing operational difficulty and saving time and costs.

[0047] In an optional embodiment, the vessel lid 11 has at least one feed port 13 to provide a channel for materials to enter the reaction chamber 12, allowing the materials to be smoothly fed into the reactor to participate in the reaction. The bottom of the vessel body 10 has at least one discharge port 14 to allow the materials to be discharged after the reaction is completed.

[0048] In other embodiments, the feed inlet 13 and the discharge outlet 14 may also be located on the side wall or other parts of the vessel body 1 as needed.

[0049] The number of inlet ports 13 and outlet ports 14 at the bottom of the vessel body 10 can be one, two, or more. If the reaction process involves the sequential addition of multiple components, multiple inlet ports 13 can be provided on the vessel lid 11, each corresponding to a different material. The order and flow rate of addition are controlled by pipeline valves to avoid premature mixing of materials, which could affect the reaction effect. When the product needs to be collected in stages or has different purity requirements, multiple outlet ports 14 can be provided at the bottom of the vessel body 10. Multiple outlet ports 14, in conjunction with a liquid level sensor, can achieve stratified discharge, improving product quality.

[0050] In an optional embodiment, a seal can be installed at the connection between the vessel body 10 and the vessel cover 11 to ensure a tight fit and effectively prevent leakage of substances within the reaction chamber 12. Simultaneously, it can prevent external factors from interfering with the reaction process. A seal can also be installed at the feed inlet 13 to prevent leakage and the entry of external impurities during material addition. A seal can also be installed at the discharge outlet 14 to ensure that materials do not leak out during the reaction and to maintain a sealed environment in the reaction chamber 12 when no material is being discharged. These seals can be installed individually or in combination. That is, seals are provided at the connection between the vessel body 10 and the vessel cover 11, and / or at the feed inlet 13, and / or at the discharge outlet 14.

[0051] In an optional embodiment, the seal may include a rubber sealing ring or a sealing strip, and the seal is fixed in place by means of interference fit or bolt tightening to achieve a good sealing effect. The seal effectively prevents leakage of materials within the reaction chamber, reducing material loss and lowering production costs. It also prevents the leakage of hazardous chemicals and other materials from posing hazards to operators and the production environment. Furthermore, it prevents external impurities from entering the reaction chamber, ensuring the reaction takes place in a pure environment, which is beneficial for improving the reaction conversion rate and product purity, thus enhancing product quality.

[0052] In an optional embodiment, sealing valves may also be installed at the inlet 13 and outlet 14. For example, double gate sealing valves can be installed at the inlet 13 and outlet 14, whose double sealing structure can effectively prevent leakage. For reactions containing corrosive gases, bellows sealing valves can be installed at the inlet 13 and outlet 14. The elastic compensation of the bellows and the packing-free structure prevent the medium from directly contacting the sealing components, thus extending the service life of the valve.

[0053] In an optional embodiment, the vessel lid 11 may also be provided with an observation window, a pressure sensor interface, a temperature sensor interface, etc., for observing the reaction and monitoring reaction parameters.

[0054] In an optional embodiment, the reaction vessel further includes: The control component 5 includes a speed adjustment module and / or a steering adjustment module. The speed adjustment module and / or the steering adjustment module are electrically connected to the drive component 3 and are used to adjust the rotation speed of the drive component 3 and / or control the steering direction (forward or reverse) of the drive component 3, thereby controlling the stirring speed and / or stirring direction of the stirring component 2.

[0055] In an optional implementation, the speed regulation module can be implemented using a high-performance programmable logic controller (PLC) combined with a frequency converter. The PLC, as the core control unit, possesses powerful logic operation and data processing capabilities, and can precisely control the output frequency of the frequency converter according to a preset program and input parameters. The frequency converter is connected to the drive component 3 (such as a motor), and adjusts the motor speed by changing the output frequency. When rapid stirring is required, the PLC adjusts the output frequency of the frequency converter to a higher value according to the preset program, at which point the motor speed can reach near the rated speed, and the stirring component 2 stirs at a higher speed; when the stirring speed needs to be reduced, the PLC reduces the output frequency of the frequency converter, the motor speed decreases accordingly, and the stirring speed slows down.

[0056] Furthermore, the steering adjustment module can be implemented by setting a forward / reverse control circuit in the circuit of the drive component 3. This circuit is generally composed of electrical components such as contactors and relays. When it is necessary to change the stirring direction, the PLC sends a corresponding control signal to control the action of the contactors and relays, thereby changing the power supply phase sequence of the motor and realizing the forward and reverse rotation of the motor. For example, after stirring for a period of time, the PLC, according to a preset program, uses the forward / reverse control circuit to switch the motor from forward to reverse rotation, or vice versa, and the stirring direction of the stirring component 2 also changes accordingly.

[0057] The speed control module and the direction control module work together to achieve precise control of the stirring process. By accurately controlling the stirring speed and direction, the reactants can be more thoroughly mixed and contacted within the reactor, accelerating the reaction rate. Simultaneously, appropriate stirring speed and direction ensure the uniformity and stability of the reaction, reduce side reactions, and improve the purity and quality of the product.

[0058] See Figure 2 and Figure 4 As shown, in an optional embodiment, the reactor further includes a filter assembly 7. The filter assembly 7 may be located in the region corresponding to the discharge port 14 within the reaction chamber 12, and the filter assembly 7 is used to filter and separate the solid and liquid materials formed after the reaction of the materials.

[0059] In an optional embodiment, the filter assembly 7 can be a filter screen made of high-strength, corrosion-resistant metal or polymer material, with an pore size that can be set according to actual needs to effectively intercept solid materials. Simultaneously, a support frame can be provided to fix the filter screen and ensure its stability under material impact. The filter assembly 7 effectively separates solid and liquid materials, reduces impurities in the discharge, improves product purity and quality, and meets the demands of high-end production.

[0060] See Figure 2 and Figure 4 As shown, in an optional embodiment, the reactor further includes a spray assembly 8. The spray assembly 8 can be arranged on top of the reaction chamber 12, and the spray assembly 8 is used to spray and wash the material.

[0061] Furthermore, the spray assembly 8 is circumferentially arranged at the top of the reaction chamber 12. In an optional embodiment, the spray assembly 8 may include an annular pipe, nozzles, and a connection interface. The annular pipe surrounds the top of the reaction chamber to ensure comprehensive spray coverage. The nozzles are evenly distributed on the pipe, and the spray angle and range can be adjusted as needed. The connection interface is used to connect to an external washing liquid supply system. The spray assembly 8 washes the materials, removes byproducts and impurities generated during the reaction, promotes the forward reaction, and improves the reaction conversion rate and selectivity.

[0062] In one alternative implementation, see [link to relevant documentation] Figure 1 and Figure 2 As shown, the vessel body 10 is covered with at least one heat insulation layer 4.

[0063] In an optional embodiment, the vessel body 10 adopts a double-layer jacketed structure, forming a sealed annular space between the inner and outer layers. This sealed annular space serves as a water-insulated cavity, i.e., insulation layer 4. This annular water-insulated cavity surrounds the reaction chamber 12. The vessel body 10 is equipped with at least one hot water inlet and a corresponding number of drain outlets. Hot water is injected through the inlet to insulate the reaction chamber 12. To reduce heat loss, the walls of the water-insulated cavity are covered with thermal insulation material to ensure insulation effectiveness. With this design, under ambient temperature fluctuations of ±10℃, the insulation layer 4 can precisely control the temperature fluctuation within the reaction chamber 12 to within ±1℃, providing a stable temperature environment for the material reaction and effectively ensuring the stability of the reaction and product quality. The insulation layer 4 reduces heat loss or absorption during the reaction process, maintains a constant temperature environment in the reaction chamber 12, ensures the reaction proceeds under optimal temperature conditions, avoids problems such as incomplete reaction and increased side reactions caused by temperature fluctuations, and improves product quality and yield.

[0064] Furthermore, the feed inlet 13 and / or the discharge outlet 14 are provided with control valves 6 for controlling the flow rate.

[0065] Control valve 6 is made of corrosion-resistant and pressure-resistant metal materials to ensure long-term stable operation in the working environment of the reactor. Control valve 6 can be designed in different shapes, such as spherical or conical, to meet different flow control requirements. Furthermore, control valve 6 can be manually controlled or connected to control assembly 6 to achieve automated control.

[0066] Control valve 6 can be installed at the inlet 13 and outlet 14 respectively according to actual production needs. It is tightly connected to each port through flange connection, threaded connection or other means to ensure the sealing of the connection and prevent fluid leakage.

[0067] In an optional embodiment, the outer surface of the stirring shaft 20 and / or the outer surface of the stirring blade 21 are both covered with a wear-resistant and corrosion-resistant coating.

[0068] In an optional embodiment, the wear-resistant and corrosion-resistant coating can be a tungsten carbide coating, a nickel-based alloy coating, or a ceramic coating, with the specific material selected according to actual needs. Tungsten carbide has extremely high hardness and excellent wear resistance, while also possessing certain corrosion resistance. When the material processed in the reactor contains a large number of hard particles, such as in the slurry reaction after grinding certain ores, the stirring shaft 20 and stirring blades 21 will suffer severe wear. In this case, applying a tungsten carbide coating to the outer surface of the stirring shaft 20 and stirring blades 21 can effectively resist the wear of hard particles. Nickel-based alloys have excellent corrosion resistance and can maintain good stability in various corrosive media such as strong acids and strong alkalis. If the material processed in the reactor is a strongly acidic chemical solution, such as sulfuric acid or hydrochloric acid, the stirring shaft 20 and stirring blades 21 will face serious corrosion problems. Using a nickel-based alloy coating can effectively prevent the chemical solution from corroding the stirring components. Ceramic coatings combine wear resistance and corrosion resistance, and also have good high-temperature resistance. In some high-temperature and highly corrosive reaction environments, such as the sintering precursor reaction of certain ceramic materials, ceramic coatings can meet the usage requirements of the stirring shaft 20 and stirring blades 21. Furthermore, wear-resistant and corrosion-resistant coatings can be applied to the outer surfaces of the stirring shaft 20 and stirring blades 21 through thermal spraying or electroplating processes.

[0069] From the perspective of extending equipment lifespan, the wear-resistant and corrosion-resistant coating effectively isolates the stirring shaft 20 and stirring blades 21 from direct contact with the material, preventing solid particles in the material from causing wear on the stirring components, and preventing chemical corrosion of the stirring components. This significantly reduces the wear of the stirring components, extends the service life of the stirring assembly 2, and lowers the maintenance and replacement costs of the equipment. From the perspective of improving reaction stability, the integrity of the stirring components ensures the stability and uniformity of the stirring process, allowing the material to be fully and uniformly mixed in the reactor, avoiding uneven mixing caused by wear or corrosion of the stirring components, thereby improving the stability of the reaction and the quality of the product. From the perspective of adapting to complex working conditions, the wear-resistant and corrosion-resistant coating gives the stirring shaft 20 and stirring blades 21 stronger adaptability, enabling the reactor to handle more types and more complex materials, thus broadening the application range of the reactor.

[0070] The beneficial effects of this application are as follows: By incorporating a stirring assembly including a stirring shaft and multiple stirring blades within the reactor vessel, with the stirring shaft connected to a drive assembly and extending into the reaction chamber to rotate axially around the vessel body, the stirring process becomes more efficient. Multiple stirring blades are arranged around the end of the stirring shaft extending into the reaction chamber, and each blade is distributed at a different angle, enabling the generation of more complex material flow patterns. The stirring blades at different angles can stir the material from multiple directions, resulting in more thorough mixing, improved reaction rate and product uniformity, thereby enhancing product quality.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
