Description

Technical Field

[0001] This application belongs to the field of reaction vessel technology, specifically relating to a reaction vessel. Background Technology

[0002] In industrial production fields such as chemical, pharmaceutical, food, and coatings, reaction vessels are core equipment for realizing processes such as material mixing, reaction, and dispersion. Their operating efficiency and material handling effect directly affect product quality and production efficiency. To improve the uniformity of materials within the reaction vessel, a stirring device is usually installed inside the vessel. The rotation of the stirring device drives the material flow, thereby achieving full contact and reaction of the materials.

[0003] However, in actual production processes, when the stirring device rotates at high speed, a large amount of material tends to adhere to the outer surface of its rotating parts due to the viscosity, surface tension, or reaction characteristics of the material. If this adhered material is not cleaned for a long time, it will lead to material waste and may also deteriorate or solidify due to prolonged retention, thereby affecting the purity of subsequent reactions and even contaminating the entire batch of material.

[0004] Meanwhile, during the material stirring and reaction process, due to the physical properties of the materials themselves or the entrainment of gases generated during the reaction, some materials may float on the surface of the liquid inside the reactor, forming clumps that are difficult to disperse. If these floating material clumps cannot be effectively broken up and dispersed, it will lead to uneven mixing of materials, reduce the reaction rate, and even cause incomplete local reactions, affecting the performance indicators of the final product. Utility Model Content

[0005] To overcome at least one of the aforementioned drawbacks, this application provides a reaction vessel. The objective of this application can be achieved by employing the following technical solution:

[0006] This application provides a reaction vessel, comprising:

[0007] The vessel body;

[0008] A stirring device, wherein the rotatable part of the stirring device is disposed inside the vessel body;

[0009] A dispersing device, comprising a fixed frame disposed within the vessel body, wherein a scraper and a dispersing plate are mounted on the fixed frame; wherein...

[0010] The scraper is located at the gas-liquid boundary inside the vessel and is used to contact the material adhering to the outer peripheral surface of the rotatable part.

[0011] The dispersing plate is located on the side of the scraper away from the rotatable part, and the dispersing plate is used to agitate material clumps floating on the surface of the liquid in the vessel.

[0012] Optionally, the fixing frame is further provided with a guide plate, which is located on the side of the dispersing plate away from the scraper. The guide plate extends along the axial direction of the rotatable part and is used to roll the material agglomerates floating on the liquid surface into the liquid phase body.

[0013] Optionally, at least four scrapers are provided, and the at least four scrapers are evenly arranged along the circumference of the rotatable portion.

[0014] Optionally, at least four dispersing plates are provided, and the at least four dispersing plates are evenly arranged along the circumference of the rotatable portion.

[0015] Optionally, at least four of the dispersing plates and at least four of the scrapers are arranged in a one-to-one correspondence along the radial direction of the rotatable portion.

[0016] Optionally, the reaction vessel further includes:

[0017] The lid is fastened to the top opening of the vessel body, and the lid and the vessel body are sealed together by a sealing ring.

[0018] Optionally, the vessel lid is provided with a feed inlet and a liquid inlet, and the liquid inlet is connected to a separating funnel.

[0024] By employing the above technical solution, this application has at least the following beneficial effects:

[0025] The reaction vessel provided in this application, by installing a scraper at the gas-liquid interface within the vessel body and placing it in contact with the outer peripheral surface of the rotatable part of the stirring device, can promptly scrape off material adhering to the outer peripheral surface of the rotatable part of the stirring device. This prevents material from deteriorating and solidifying due to long-term retention, reducing material waste and preventing contamination of reaction purity by the adhering material. By installing a dispersing plate on the side of the scraper away from the rotatable part, it can specifically impact and break up material clumps floating on the liquid surface within the vessel body, dispersing them into the liquid. This ensures uniform mixing of materials, improves the reaction rate and reaction completeness, avoids localized incomplete reaction problems caused by clumping, and guarantees the performance indicators of the final product.

[0033] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0034] See also Figure 1 and Figure 2 As shown, according to an embodiment of this application, a reaction vessel is provided, including a vessel body 1, a stirring device 2, and a dispersing device 3; the rotatable part of the stirring device 2 is disposed inside the vessel body 1; the dispersing device 3 includes a fixing frame 31, which is disposed inside the vessel body 1, and a scraper 32 and a dispersing plate 33 are disposed on the fixing frame 31; wherein, the scraper 32 is located at the gas-liquid boundary inside the vessel body 1, and is used to contact the material attached to the outer peripheral surface of the rotatable part; the dispersing plate 33 is located on the side of the scraper 32 away from the rotatable part, and the dispersing plate 33 is used to agitate the material clumps floating on the liquid surface inside the vessel body 1.

[0035] In this embodiment, by installing a scraper 32 at the gas-liquid interface inside the vessel 1 and having it contact the outer peripheral surface of the rotatable part of the stirring device 2, material adhering to the outer peripheral surface of the rotatable part of the stirring device 2 can be scraped off in a timely manner. This prevents the material from deteriorating and solidifying due to long-term retention, reducing material waste and preventing contamination of the reaction purity by the adhering material. By installing a dispersing plate 33 on the side of the scraper 32 away from the rotatable part, material clumps floating on the liquid surface inside the vessel 1 can be targeted and broken up and dispersed into the liquid. This ensures uniform mixing of the material, improves the reaction rate and reaction completeness, avoids local incomplete reaction problems caused by clumps, and guarantees the performance indicators of the final product.

[0036] Among them, the vessel body 1 is the main structure of the reactor, which can be a closed or semi-closed container, providing space for the reaction, mixing and other processes of materials.

[0037] The stirring device 2 includes a driving part and a rotatable part. The driving part is fixedly installed on the top or outside of the vessel body 1, and its output shaft extends into the vessel body 1 through a sealing structure. The rotatable part includes a stirring shaft and at least one stirring blade. The top end of the stirring shaft is connected to the output shaft of the driving part, and the bottom end is suspended in the inner cavity of the vessel body 1. The driving assembly is used to drive the rotatable part to rotate around the axial direction through the output shaft, so as to achieve stirring and mixing of the materials in the vessel body 1.

[0038] Specifically, the drive unit includes, but is not limited to, power equipment such as a motor and a reducer, which is fixed to the sealed end cover on the top of the vessel body 1 by bolts or flanges; the rotatable part includes a coaxially arranged stirring shaft and at least one set of stirring blades, the top end of which is connected to the output shaft of the drive unit via a coupling, and the bottom end extends into the reaction zone inside the vessel body 1. In the working state, the torque output by the drive unit is transmitted to the stirring blades through the stirring shaft, causing the material inside the vessel body 1 to flow axially or radially, thereby achieving uniform mixing and chemical reaction of the material.

[0039] The dispersing device 3 mainly consists of a fixed frame 31, a scraper 32, and a dispersing plate 33. The fixed frame 31 is installed inside the vessel body 1, supporting the scraper 32 and the dispersing plate 33 to ensure their stable function. The scraper 32 is located at the gas-liquid interface inside the vessel body 1. When the rotatable part of the stirring device 2 rotates, the scraper 32 contacts the outer surface of the rotatable part, scraping off the material adhering to it. This prevents the material from accumulating and deteriorating on the surface of the rotatable part, thus ensuring the stirring effect and avoiding material waste and contamination. The dispersing plate 33 is located on the side of the scraper 32 furthest from the rotatable part of the stirring device 2, that is, closer to the inner wall of the vessel body 1. During the material reaction or mixing process, some clumps may float on the liquid surface. As the stirring device 2 rotates, the dispersing plate 33 impacts these clumps, breaking them into smaller pieces, allowing them to be better dispersed in the liquid and improving the uniformity of the mixture.

[0040] Specifically, the fixing frame 31 is a ring structure, arranged in three layers along the vertical direction of the vessel body 1, i.e., axially spaced, from top to bottom: top layer, middle layer, and bottom layer. The bottom layer is fixedly connected to the inner wall or bottom of the vessel body 1, such as by bolts or welding, serving as the supporting foundation for the entire fixing frame 31. It transmits the weight of the three-layer ring structure and the force generated during operation to the vessel body 1, ensuring the overall installation stability of the fixing frame 31 within the vessel body 1. The middle layer mainly serves as a connection and reinforcement, and can be fixedly connected to the ring frame of the top and bottom layers through stiffeners, enhancing the structural stability of the entire fixing frame 31 and preventing the top layer from shaking when the scraper 32 contacts the stirring component or the dispersing plate 33 impacts the agglomerates. The top layer serves as the mounting carrier for the scraper 32 and the dispersing plate 33. Both the scraper 32 and the dispersing plate 33 are fixed to the ring frame of this layer, and they are distributed radially at intervals along the ring frame to respectively achieve the scraping function for the rotatable part of the stirring device 2 and the dispersing function for the agglomerates on the liquid surface.

[0041] Furthermore, to achieve continuous and efficient scraping of the outer peripheral surface of the rotatable part, the scraper 32 can be configured as an arc-shaped structure extending along the axial direction of the rotatable part, and the radius of curvature of the arc-shaped structure is adapted to the curvature of the outer peripheral surface of the rotatable part, so that the scraper 32 forms a line contact or a small-area surface contact with the outer peripheral surface of the rotatable part, so as to continuously scrape off the material adhering to its surface during the rotation of the rotatable part. Specifically, to achieve effective scraping of the outer peripheral surface of the rotatable part, the radius of curvature R1 of the scraper 32 and the radius of curvature R0 of the outer peripheral surface of the rotatable part satisfy the following relationship: |R1-R0|≤5%R0. In the preferred embodiment, 0.95R0≤R1≤1.05R0. Here, the rotatable part refers to the stirring shaft of the stirring device 2.

[0042] Furthermore, to efficiently impact and break up material clumps floating on the liquid surface inside the vessel 1, while minimizing excessive disturbance to the liquid surface to avoid material splashing, the dispersing plate 33 can be configured as a plate-like structure extending radially along the fixing frame 31, with serrated or ridged protrusions on the side facing the material clumps. Specifically, the dispersing plate 33 can be a straight plate or a slightly arc-shaped plate, extending radially outward along the fixing frame 31, i.e., away from the rotatable part of the stirring device 2, with a length adapted to the radial range of the liquid surface inside the vessel 1, ensuring coverage of areas where clumps easily float; at the same time, the working surface of the plate facing the clumps has evenly spaced serrations or strip-shaped ridges, increasing the contact area and impact intensity with the clumps; and it is also inclined at 30 to 60 degrees to the liquid surface, which facilitates direct impact on the clumps and guides the broken material to flow downwards in the liquid.

[0043] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2As shown, a guide plate 34 is also provided on the fixed frame 31. The guide plate 34 is located on the side of the dispersing plate 33 away from the scraper 32. The guide plate 34 extends along the axial direction of the rotatable part and is used to roll the material clumps floating on the liquid surface into the liquid phase body.

[0044] In this embodiment, the guide plate 34 actively guides material agglomerates on the liquid surface toward the liquid phase, preventing agglomerates from floating on the liquid surface for extended periods without being impacted by the dispersing plate 33. Thus, even if some agglomerates do not directly contact the dispersing plate 33, they can be drawn into the liquid by the guide plate 34, ensuring that all floating agglomerates enter the effective range of the dispersing plate 33 or the liquid phase environment, reducing agglomerate residue. It is understood that by drawing the agglomerates into the liquid phase, the flow of the liquid and the action of the stirring device 2 can assist in further dispersing the agglomerates in the liquid. Simultaneously, the liquid phase environment provides better dissolution or mixing conditions for the small pieces of material broken up by the dispersing plate 33, accelerating the fusion speed between the material and the liquid.

[0045] The guide plate 34 is part of the dispersing device 3. It is fixed on the fixing frame 31 and located on the side of the dispersing plate 33 away from the scraper 32, that is, the guide plate 34 is located in the direction where the dispersing plate 33 is closer to the inner wall of the vessel body 1. At the same time, the guide plate 34 extends along the axial direction of the rotatable part of the stirring device 2, and its length is adapted to the liquid depth in the vessel body 1.

[0046] Specifically, in a scenario where the fixed frame 31 is a three-layer annular structure consisting of a top layer, a middle layer, and a bottom layer, the guide plate 34 can be installed on the middle layer annular frame, with its extension direction simultaneously facing both the top and bottom annular frames. That is, it extends upwards along the axial direction of the vessel 1 to a position near the top annular frame and downwards to a position near the bottom annular frame, forming an axial extension structure that penetrates the middle layer and connects the top and bottom layers. It should be noted that the extension direction of the guide plate 34 matches the axial flow field formed by the liquid driven by the rotating agitator 2. When the rotatable part of the agitator 2 rotates, the liquid inside the vessel 1 forms an axial circulating flow. The upper layer of liquid is driven upwards or downwards by the agitator blades, while the lower layer of liquid replenishes it in the opposite direction, forming a closed-loop flow field. The axial extension structure of the guide plate 34 is embedded in this flow path, guiding the flow direction of the liquid through its own surface. For example, when the liquid flows upwards or downwards axially, the wall of the guide plate 34 constrains the liquid, enhancing the stability of the axial flow. Material agglomerates floating on the liquid surface are captured by the guide plate 34 as the liquid flows axially, and then moved towards the bulk liquid phase under the influence of the flow field. Here, the bulk liquid phase refers to the interior of the liquid. It is understood that agglomerates on the liquid surface are typically concentrated in the area between the scraper 32 and the inner wall of the vessel 1, and the guide plate 34, located outside the dispersing plate 33, precisely covers this area, ensuring that the agglomerates can be contacted and guided. Since the guide plate 34 extends axially, its height covers the space from near the top to the bottom. When the liquid flows along the surface of the guide plate 34 under stirring, a directional flow velocity is formed from the surface downwards. As the agglomerates move with the liquid, they are pulled into the bulk liquid phase by this vertical flow velocity, rather than remaining on the surface. In practical applications, after the dispersing plate 33 breaks large pieces of material into smaller clumps, these small pieces may still float on the liquid surface. If only the stirring blades disturb them, they may not be able to quickly enter the liquid phase. However, the guide plate 34 can actively draw these broken small pieces into the liquid phase by guiding the liquid flow, so that they can mix with the liquid more quickly and avoid re-agglomeration, thereby improving the uniformity of material dispersion and reaction efficiency.

[0047] Furthermore, in order to ensure that floating material agglomerates in different areas of the liquid surface inside the vessel 1 can be effectively guided, improve the comprehensiveness of the flow coverage, and avoid agglomerate retention due to lack of flow in local areas, at least four flow guide plates 34 can be set at circumferential intervals along the middle annular frame of the fixed frame 31. This will form a comprehensive coverage of the liquid surface through multiple evenly distributed flow guide plates 34, synergistically enhancing the entrainment effect of floating agglomerates and ensuring that the material can more fully enter the liquid phase to participate in the reaction.

[0048] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2As shown, at least four scrapers 32 are provided, and at least four scrapers 32 are evenly arranged along the circumference of the rotatable part.

[0049] In this embodiment, at least four scrapers 32 are provided to improve the scraping effect or work efficiency. For example, when cleaning materials adhering to the inner wall of the equipment, multiple scrapers 32 can work simultaneously. Compared with a single or a few scrapers 32, the cleaning task can be completed in a shorter time, and the severe wear caused by a single scraper 32 working for a long time can be avoided, thereby extending the overall service life.

[0050] In the scenario where the fixed frame 31 is a three-layer ring structure consisting of a top layer, a middle layer, and a bottom layer, radial rods can be connected to the top ring frame through welding, bolts, or other means. The radial rods serve as the mounting carriers for the scraper 32, providing mounting points for the scraper 32.

[0051] Specifically, in this embodiment, four scraper blades 32 are provided, and the number of radial rods corresponds one-to-one with the number of scraper blades 32. The four radial rods are evenly distributed at 90-degree intervals along the circumference of the top-level annular frame, forming a cross-shaped and extending support pattern. Each radial rod has a reserved mounting surface adapted to the scraper blade 32 on the side facing the rotatable part. If welding is used for fixing, the back of the scraper blade 32 is attached to the rod, and continuous welds are used to ensure a rigid connection between the scraper blade 32 and the radial rod, which can withstand the friction and material impact during scraping. If bolt connection is used, bolt holes are opened on the radial rods and scraper blades 32 respectively, and high-strength bolts are used for fastening. The scraper blade 32 can also be easily disassembled and replaced later.

[0052] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, at least four dispersing plates 33 are provided, and at least four dispersing plates 33 are evenly arranged along the circumference of the rotatable part.

[0053] In this embodiment, at least four dispersing plates 33 are evenly arranged circumferentially along the rotatable portion, covering the radial area of ​​the liquid surface inside the vessel 1 from multiple angles, preventing clumping and retention caused by the absence of dispersing plates 33 in certain areas. For example, when the stirring device 2 rotates the liquid, floating material clumps will move in a circular motion with the liquid. The evenly distributed dispersing plates 33 can form an all-round interception along the movement path of the clumps, ensuring that clumps at different positions are effectively impacted, reducing the probability of missed impact. At the same time, the multiple dispersing plates 33, in conjunction with the rotation of the rotatable portion, can increase the number of collisions with the clumps per unit time. In this embodiment, compared to a few dispersing plates 33, the evenly distributed design of four or more allows the clumps to contact the dispersing plates 33 more frequently during circumferential movement, accelerating the breaking process of large clumps, shortening the time for materials to disperse into the liquid, thereby improving the overall reaction efficiency.

[0054] In the scenario where the fixed frame 31 is a three-layer ring structure consisting of a top layer, a middle layer, and a bottom layer, similar to the installation method of at least four scrapers 32, the top layer serves as the installation carrier for the disintegration plate 33. Its ring frame also has radial rods pre-set along the circumference corresponding to the number of disintegration plates 33, and the radial rods are evenly distributed along the circumference of the ring frame, that is, the central angle between adjacent radial rods is 90°, in order to match the uniform arrangement requirement of at least four disintegration plates 33.

[0055] Specifically, the radial members have a pre-reserved mounting surface for connection with the disintegration plate 33. The mounting surface can be designed as a flat surface or an arc-shaped surface to match the curvature of the disintegration plate 33 (if the disintegration plate 33 is a slightly arc-shaped plate), and the size of the mounting surface is slightly smaller than the connection end area of ​​the disintegration plate 33 to ensure a tight fit. During connection, continuous fillet welds can be used. The welds are continuously distributed along the contact edges of the two components, with a height of not less than 8mm. After welding, the slag must be removed and non-destructive testing performed to ensure there are no defects such as incomplete welds or slag inclusions. This allows the disintegration plate 33 and the radial members to form a rigid whole, capable of withstanding significant impact forces, making it suitable for scenarios where materials agglomerate with high hardness and high impact force.

[0056] In the above embodiments, participants Figure 1 and Figure 2 As shown, at least four dispersing plates 33 and at least four scrapers 32 are arranged in a one-to-one correspondence along the radial direction of the rotatable portion.

[0057] Here, since the scraper 32 and the dispersing plate 33 are evenly distributed along the circumference of the rotatable part and correspond one-to-one radially, they form a matched processing unit in the circumferential position. Each scraper 32 is responsible for scraping material in a specific circumferential area, while the corresponding dispersing plate 33 simultaneously covers the liquid surface in that area, ensuring that the scraped material in each circumferential position within the vessel 1 can be specifically crushed, avoiding blind spots in material processing caused by misalignment of the scraper 32 and the dispersing plate 33 in local circumferential areas. It can be understood that the material scraped by the scraper 32 will fall directly onto the liquid surface, and the dispersing plate 33, which corresponds to it radially, can promptly impact and crush these freshly scraped materials in that area, forming a continuous processing flow of scraping, crushing, and dispersing, preventing the scraped material from accumulating on the liquid surface and forming large clumps, thus reducing the subsequent dispersing pressure.

[0058] It should be noted that in the scenario where the dispersing plate 33 and the scraper 32 are arranged in a one-to-one correspondence along the radial direction of the rotatable part, the dispersing plate 33 and the scraper 32 arranged radially opposite each other can share the same radial rod.

[0059] Furthermore, in order to improve the bending strength of radial members, the cross-section of radial members can be rectangular or I-shaped to avoid deformation under stress.

[0060] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the reactor also includes a lid 4, which is fastened to the top opening of the reactor body 1, and the lid 4 and the reactor body 1 are sealed together by a sealing ring 5.

[0061] In this embodiment, the lid 4 is fastened to the open top of the vessel body 1 and sealed with a sealing ring 5, effectively preventing the exchange of substances between the inside and outside of the vessel body 1. For chemical reactions that need to be carried out in a closed environment, this prevents the volatilization and leakage of materials inside the reactor, thus preventing waste or environmental pollution. It also prevents external air, moisture, and other impurities from entering the vessel body 1 and contaminating the materials, ensuring that the reaction takes place in a pre-set pure environment and guaranteeing the purity and stability of the reaction. Simultaneously, the lid 4 and the vessel body 1 are sealed together by the sealing ring 5, forming a closed pressure vessel to prevent pressure leakage. This allows the pressure environment required for the reaction to be maintained stably inside the vessel body 1, ensuring that the reaction proceeds at the expected rate and extent, and preventing reaction failure or substandard product performance due to unstable pressure.

[0062] The vessel lid 4 is a top sealing component of the reactor, used to cover the open area at the top of the vessel body 1, thus creating a relatively enclosed space inside the vessel body 1. It is understood that the vessel lid 4, sealed to the vessel body 1 by the sealing ring 5, can constitute the aforementioned sealed end cap.

[0063] Specifically, the sealing ring 5 can be made of elastic materials such as rubber or silicone. When the lid 4 and the body 1 are fastened together, the sealing ring 5 is squeezed between the contact surfaces of the two, filling the tiny gaps and blocking the flow of media inside and outside the body 1.

[0064] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the lid 4 has a feed inlet 6 and a liquid inlet 7, and the liquid inlet 7 is connected to a separating funnel 8.

[0065] In this embodiment, the separate arrangement of the feed inlet 6 and the liquid inlet 7 allows for the separate addition of solid and liquid materials, avoiding interference between materials in different states during the addition process and ensuring the accuracy and orderliness of material addition. For example, solid raw materials are added through the feed inlet 6, and liquid reagents are added through the liquid inlet 7, with each channel operating independently, reducing the possibility of premature material mixing.

[0066] In this embodiment, the separating funnel 8 has a controllable piston or valve structure. When liquid material enters the reactor through the inlet 7, the dropping rate and amount of material can be precisely adjusted using the separating funnel 8. This achieves the goal of controlling the reaction process. For example, in some exothermic reactions, slow and quantitative addition of material can prevent the reaction from becoming too vigorous and ensure a stable reaction.

[0067] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the lid 4 is also provided with a temperature measuring port 9 and a condensation port 10. The temperature measuring port 9 is used to insert a temperature measuring rod 11 into the body 1, and the condensation port 10 is used to connect to the condenser tube 12.

[0068] In this embodiment, the temperature measuring port 9 allows the temperature measuring rod 11 to be directly inserted into the reactor body 1, enabling real-time and accurate monitoring of temperature changes in the materials inside the reactor. During chemical reactions, temperature is a critical factor affecting reaction rate, product purity, and reaction safety. For example, some exothermic reactions may lead to material decomposition or even danger if the temperature is too high. Real-time monitoring by the temperature measuring rod 11 allows operators to promptly grasp the temperature dynamics and, by adjusting the heating or cooling devices, control the reaction temperature within a suitable range, ensuring stable reaction progress.

[0069] In this embodiment, after the condenser port 10 is connected to the condenser pipe 12, volatile gases or vapors generated during the reaction can be condensed and recovered. On the one hand, this avoids the loss of volatile materials and improves the utilization rate of raw materials, especially for expensive or toxic materials, reducing waste and environmental pollution. On the other hand, it prevents the accumulation of volatiles in the reactor, which could lead to increased pressure, reducing the risk of the reactor becoming dangerous due to excessive pressure. At the same time, it can also maintain the stability of the reaction environment inside the reactor, ensuring that the reaction proceeds according to the expected stoichiometry.

[0070] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 As shown, the reactor also includes a fixed platform 13, which includes a vertical part and a horizontal part. The vertical part is used to support the condenser tube 12, and the horizontal part is used to support the reactor body 1.

[0071] In this embodiment, the horizontal part is used to support the vessel body 1, which can prevent the vessel body 1 from shaking or shifting due to internal material stirring and temperature changes during the reaction process, ensuring that the sealing structure between the vessel body 1 and the vessel cover 4 remains stable and reducing the risk of leakage.

[0072] In this embodiment, the vertical support for the condenser tube 12 can fix the installation angle and position of the condenser tube 12, prevent the condenser tube 12 from shaking due to its own weight or the flow of condensate, ensure the sealing of its connection with the condenser port 10 on the lid 4, and ensure the efficient operation of the condensation system.

[0073] The vertical part refers to the structure in the fixed platform 13 that extends vertically. For example, a support or column that is perpendicular to the ground.

[0074] The horizontal section refers to the structure in the fixed platform 13 that extends horizontally. For example, a pallet, flat plate, or bracket parallel to the ground.
