Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a polymerization reactor with a safety inspection port. Background Technology

[0002] Polymerization reactors are the core equipment for realizing polymer polymerization reactions. Their purpose is to provide a controllable, sealed environment for the polymerization reaction, precisely controlling key parameters such as temperature, pressure, stirring rate, and reaction time to ensure that monomers are converted into polymers according to a preset chemical pathway. The aim is to ensure the safety and stability of the reaction, preventing reactant leakage, oxidation, or excessive side reactions; and to improve product quality by precisely controlling parameters to achieve polymer molecular weight and structural uniformity, meeting the performance requirements of different applications. Cleaning of polymerization reactors typically involves using high-pressure water jets to clean the interior, removing residual polymers, reactants, and impurities to prevent contamination of subsequent batches and ensure product purity and performance stability. It also prevents residual substances from adhering and causing reduced heat transfer efficiency and equipment corrosion. Maintenance involves using sensors or other equipment to check for wear and tear on components and ensure accurate operating parameters. Cleaning reduces product defect rates and ensures production continuity; maintenance promptly eliminates safety hazards, extends equipment lifespan, reduces losses from sudden downtime, and ultimately maintains stable polymerization processes, ensuring safe, efficient, and high-quality industrial production.

[0003] In existing technologies, some reactors are typically cleaned by directly rinsing with water, and maintenance is usually carried out by checking internal sensors. This can lead to blind spots during cleaning, and the sensors may misjudge due to the influence of the internal environment. Furthermore, sensor damage can affect internal maintenance. Therefore, a polymerization reactor with a safety maintenance port is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a polymerization reactor with a safety inspection port, which aims to improve the problem that direct water rinsing of the interior can easily cause cleaning dead spots and the problem that sensors may misjudge the internal condition due to damage or environmental issues.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A polymerization reactor with a safety inspection port includes a reactor, a discharge port fixedly connected to the top of the reactor, an inspection port fixedly connected to the top of the reactor, a discharge mechanism installed on the inner wall of the reactor, an inspection mechanism installed inside the reactor, a protective box fixedly connected to the bottom of the reactor, and the inspection mechanism including a protective cover. The top of the protective cover is fixedly connected to the inside of the reactor, a door is rotatably connected to the outer wall of the protective cover, a first ladder is fixedly connected to the inside of the protective cover, a second ladder is rotatably connected to the bottom of the first ladder, and a folding assembly is installed on the inner wall of the first ladder. Preferably, the protective cover can protect the internal ladders one and two, preventing materials from adhering to the ladder structure and causing corrosion or contamination during normal operation of the reactor, thus extending the service life of the maintenance mechanism. The rotating connection design of the cover door allows it to be opened for personnel to enter and exit during maintenance, and closed when not in maintenance mode to prevent materials from sticking to the ladders. The rotating connection between ladder one and ladder two provides a structural basis for the folding and unfolding of the ladders. In the folded state, it can reduce the space occupied by the maintenance mechanism in the reactor and avoid interfering with the normal reaction process of the reactor. In the unfolded state, it can provide personnel with a stable passage from the maintenance port to the bottom of the reactor, ensuring the smooth conduct of maintenance operations.

[0006] As a further description of the above technical solution: The folding assembly includes an L-shaped groove rod, the bottom of which is fixedly connected to the top of the second ladder. A limit plate is slidably connected to the inner wall of the second ladder, and a sealing plate is fixedly connected to the bottom of the limit plate. Preferably, the L-shaped groove rod is fixedly connected to the second ladder and can move synchronously with the rotation of the second ladder. Its groove structure provides a locking point for the limiting plate, which is the key structure for fixing and unlocking the second ladder. The sliding connection between the limiting plate and the second ladder ensures that the limiting plate can move stably up and down. By engaging or disengaging with the L-shaped groove rod, the fixed state of the second ladder can be precisely controlled. The sealing plate is fixedly connected to the limiting plate and can slide synchronously with the limiting plate. When the limiting plate limits the L-shaped groove rod, the sealing plate can seal the gaps in the inner wall of the first ladder, preventing material particles or liquids from entering the interior of the first ladder when the reactor is working, preventing the internal structure from being corroded or blocked, and ensuring the flexible operation of the folding assembly.

[0007] As a further description of the above technical solution: The inner wall of the first ladder is provided with a sliding groove, and the outer wall of the sealing plate is slidably connected to the inner wall of the first ladder, and the outer wall of the sealing plate is slidably connected to the inner wall of the sliding groove. Preferably, the sliding groove provides guidance and limitation for the sliding of the sealing plate, ensuring that the sealing plate can only move up and down along the trajectory of the sliding groove, avoiding deviation or jamming of the sealing plate during the sliding process, and ensuring that the sealing plate can always accurately seal the gaps in the inner wall of the ladder. At the same time, the double sliding connection between the sealing plate and the inner wall of the ladder and the inner wall of the sliding groove further improves the stability of the sealing plate's sliding, reduces frictional wear between the sealing plate and the ladder, extends the service life of the sealing plate, and also ensures the smooth operation of the folding assembly as a whole.

[0008] As a further description of the above technical solution: The inner wall of the L-shaped groove rod is slidably and detachably connected to a limiting plate, and the outer wall of the limiting plate is slidably connected to the inner wall of the ladder. Preferably, the sliding and detachable connection between the L-shaped groove rod and the limiting plate allows the limiting plate to easily engage or disengage from the groove of the L-shaped groove rod. When the limiting plate engages with the L-shaped groove rod, the second ladder can be fixed to the outside of the first ladder, maintaining the folded state of the ladder and preventing the second ladder from rotating arbitrarily during reactor operation. When the limiting plate disengages from the L-shaped groove rod, the fixed state of the second ladder is released, and the operator can rotate the second ladder to lower it to meet maintenance needs. The sliding connection between the limiting plate and the inner wall of the first ladder provides stable support for the up-and-down movement of the limiting plate, ensuring that the limiting plate can accurately engage with the L-shaped groove rod and guaranteeing the reliable implementation of the ladder fixing and unlocking functions.

[0009] As a further description of the above technical solution: A return spring is fixedly connected to the inner wall of the first ladder, and the top of the return spring is fixedly connected to the bottom of the limiting plate. Preferably, the two ends of the return spring are fixed to the inner wall of ladder one and the bottom of the limiting plate, respectively, providing elastic return force for the limiting plate: when the worker presses the limiting plate, the return spring is compressed, the limiting plate moves downward and disengages from the L-shaped groove rod, thus unlocking ladder two. When the worker releases the limiting plate, the return spring extends under the action of elastic force, pushing the limiting plate upward to reset and re-engage into the groove of the L-shaped groove rod, automatically completing the fixation of ladder two. There is no need for manual reset of the limiting plate, which simplifies the operation process of folding and unfolding the ladder and improves the convenience of maintenance work. At the same time, the return spring can always apply an upward force to the limiting plate, ensuring a tighter engagement between the limiting plate and the L-shaped groove rod, preventing the limiting plate from loosening due to vibration or other factors when ladder two is fixed, and improving the stability of ladder fixation.

[0010] As a further description of the above technical solution: The feeding mechanism includes a motor, the drive end of which is fixedly connected to a stirring rod. The bottom of the stirring rod is rotatably connected to the inside of the reaction vessel, and the top of the stirring rod is fixedly connected to a first bevel gear. Preferably, the motor serves as the power source for the feeding mechanism, with its drive end fixedly connected to the stirring rod. This allows the stirring rod to rotate stably. The bottom of the stirring rod is rotatably connected to the inside of the reactor, providing bottom support for the stirring rod and ensuring that it does not deviate or sway during rotation, thus guaranteeing the stability of the stirring rod's rotation. The first bevel gear is fixedly connected to the top of the stirring rod and can rotate synchronously with it. As a key component of the power transmission, it can transmit the power output from the motor to the second bevel gear it meshes with, thereby changing the direction of power and providing a power foundation for the subsequent rotation of the stirring paddle, ensuring the realization of the stirring function of the feeding mechanism.

[0011] As a further description of the above technical solution: The inner wall of the protective box is rotatably connected to a stirring paddle, and one end of the stirring paddle is fixedly connected to a second bevel gear. The outer side of the second bevel gear is meshed with the outer side of the first bevel gear. Preferably, the protective box protects the stirring paddle and the second bevel gear, preventing materials from directly impacting the stirring paddle and the second bevel gear during the feeding process. This reduces corrosion and wear caused by material adhesion and prevents impurities from getting entangled on the stirring paddle, affecting its rotation and extending the service life of key components of the feeding mechanism. The rotating connection between the stirring paddle and the inner wall of the protective box ensures that the stirring paddle can rotate flexibly. During its rotation, it can turn over the material below the feeding port, breaking the tendency of material accumulation and effectively preventing material from clogging the feeding port. The second bevel gear is fixedly connected to the stirring paddle and meshes with the first bevel gear, converting the power transmitted by the first bevel gear into its own rotational power, thereby driving the stirring paddle to rotate. This achieves efficient power transmission, ensuring that the speed of the stirring paddle matches the power output of the motor and guaranteeing the stability of the stirring and anti-clogging effect.

[0012] As a further description of the above technical solution: The outer wall of the reactor is provided with a discharge port, and the bottom of the motor is fixedly connected to the top of the reactor.

[0013] Preferably, the discharge port provides a discharge channel for the material after the reaction in the reactor is completed, facilitating subsequent collection and processing of the material and ensuring continuous production operations in the reactor. The bottom of the motor is fixedly connected to the top of the reactor, providing a stable installation foundation for the motor and preventing displacement or tilting of the motor due to vibration during operation. This ensures that the motor drive can stably drive the stirring rod to rotate, guaranteeing the stability of the power output of the feeding mechanism. At the same time, the motor is installed on the top of the reactor, away from the material reaction area inside the reactor, which can avoid damage to the motor caused by high temperature, corrosion and other factors, extend the service life of the motor and reduce equipment maintenance costs.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pressing the limiting plate, the pressing of the limiting plate causes the reset spring to move downward. At this time, the limiting plate is no longer stuck in the groove of the L-shaped groove rod, and then the limiting plate no longer plays a limiting role on the L-shaped groove rod. At this time, the second ladder is no longer fixed to the outside of the first ladder. At this time, rotating the second ladder can lower the second ladder, making it easier for the staff to go down to the bottom of the reactor to perform more precise maintenance and more comprehensive cleaning of the reactor.

[0015] 2. In this utility model, the motor starts and drives the stirring rod to rotate. The rotation of the stirring rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear that meshes with it to rotate. Through the transmission of the first bevel gear, the rotation of the second bevel gear drives the stirring paddle to rotate. Thus, when feeding, the stirring paddle tumbles the material, thereby preventing the material from accumulating inside the feeding port, causing blockage, production stagnation, and affecting work efficiency.

[0018] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0019] Example: Refer to Figures 1 to 3This utility model provides an embodiment of a polymerization reactor 1 with a safety inspection port 7. The reactor 1 serves as the core container for the polymerization reaction, providing a sealed and stable space to meet the polymerization process requirements. A discharge port 6 is fixedly connected to the top of the reactor 1, serving as the channel for materials to enter the reactor 1. The fixed connection ensures that materials will not leak during the discharge process and that the connection structure is robust. An inspection port 7 is also fixedly connected to the top of the reactor 1, providing an entrance for personnel to enter the reactor 1 for inspection and maintenance. The fixed connection design ensures the sealing and structural strength of the connection between the inspection port 7 and the reactor 1. A discharge mechanism 3 is installed on the inner wall of the reactor 1. This mechanism is used to agitate the materials after they enter the reactor 1, preventing material accumulation and blockage, and ensuring smooth discharge. The discharge mechanism 3, installed on the inner wall of the reactor 1, can more directly act on the incoming materials.

[0020] Specifically, reactor 1, as the core container for the polymerization reaction of materials, provides a sealed and stable space to meet the requirements of the polymerization process. The top of reactor 1 is fixedly connected to the discharge port 6, which serves as the channel for materials to enter the interior. The fixed connection can prevent leakage and ensure structural stability. The top of reactor 1 is fixedly connected to the inspection port 7, providing an entrance for personnel to enter the interior for inspection and maintenance. In addition, the inner wall of reactor 1 is equipped with a discharge mechanism 3, which can turn over the materials after they enter to avoid material accumulation and blockage, ensuring smooth discharge. Moreover, this installation position allows the mechanism to act more directly on the materials.

[0021] The reactor 1 is equipped with a maintenance mechanism 4. The maintenance mechanism 4 provides support and safety for personnel to descend to the bottom of the reactor 1 for maintenance. It can be folded up and unfolded without occupying too much working space inside the reactor 1. The bottom of the reactor 1 is fixedly connected to a protective box 5. The protective box 5 is used to protect the transmission components installed inside, preventing material adhesion, corrosion, or external impurities from entering and affecting the operation of the components. It also serves to fix the position of the internal components. The maintenance mechanism 4 includes a protective cover 41. The protective cover 41 is used to protect the ladder and other components in the maintenance mechanism 4, preventing materials from splashing onto the ladder during the reaction and causing pollution or corrosion. The top of the protective cover 41 is fixedly connected to the inside of the reactor 1. This fixing method ensures that the protective cover 41 is stable inside the reactor 1 and will not be displaced due to vibration or other external forces during the reaction process.

[0022] Specifically, the reactor 1 is equipped with a maintenance mechanism 4, which provides support and safety for personnel to go down to the bottom of the reactor for maintenance. It can be folded for storage and unfolding, avoiding taking up too much internal working space. The protective cover 41 included in the reactor 1 can protect the ladder and other components from material splashing, contamination or corrosion. The top of the protective cover 41 is fixed inside the reactor 1 to ensure positional stability and prevent displacement due to vibration or external force. The bottom of the reactor 1 is fixedly connected to a protective box 5, which can protect the internal transmission components, prevent material adhesion, corrosion and external impurities from entering and affecting operation, and fix the position of the internal components.

[0023] The outer wall of the protective cover 41 is rotatably connected to a cover door 42. The rotatable connection allows the cover door 42 to be opened or closed flexibly. When opened, it facilitates the operation of the maintenance mechanism 4 by the staff. When closed, it can cooperate with the protective cover 41 to form a closed space, further protecting the internal maintenance components. The inside of the protective cover 41 is fixedly connected to a ladder 44. The ladder 44 serves as a fixed climbing base component during maintenance. It is fixedly connected inside the protective cover 41 to ensure its load-bearing capacity and provide stable climbing support for the staff. The bottom of the ladder 44 is rotatably connected to a ladder 43. The rotatable connection design allows the ladder 43 to rotate around the bottom of the ladder 44 to fold or unfold. When unfolded, it can extend to the bottom of the reactor 1 to meet the needs of the staff to go down to the bottom of the reactor for maintenance. When folded, it can be stored outside the ladder 44 to reduce space occupation. The inner wall of the ladder 44 is equipped with a folding component 45. The folding component 45 is used to limit and fix the unfolded and folded state of the ladder 43 to ensure that the ladder 43 remains in an unfolded and fixed state during use and to avoid shaking.

[0024] Specifically, a ladder 44 is fixedly connected inside the protective cover 41, serving as a fixed climbing base component during maintenance and providing stable climbing support for personnel. A second ladder 43 is rotatably connected to the bottom of the first ladder 44. By rotating around the bottom of the first ladder 44, it can be folded or unfolded. When unfolded, it extends to the bottom of the reactor 1, meeting the needs of personnel to descend to the bottom of the reactor for maintenance. When folded, it can be stored outside the first ladder 44, reducing space occupation. In addition, a folding component 45 is installed on the inner wall of the first ladder 44, which can limit and fix the unfolded and folded state of the second ladder 43, ensuring that the second ladder 43 remains unfolded and fixed during use, preventing shaking.

[0025] When stored, it can be stably fixed to the outside of ladder 1 44. The folding component 45 includes an L-shaped groove rod 451. The L-shaped groove rod 451 cooperates with the limiting plate 454 through the groove to limit the ladder 2 43. Its structural design can accurately engage with the limiting plate 454. The bottom of the L-shaped groove rod 451 is fixedly connected to the top of ladder 2 43. The fixed connection allows the L-shaped groove rod 451 and ladder 2 43 to move synchronously. This ensures that the position of the L-shaped groove rod 451 always corresponds to the limiting plate 454 during the rotation of ladder 2 43, and the inner wall of ladder 2 43 slides. A limiting plate 454 is connected, and the sliding connection allows the limiting plate 454 to move up and down on the inner wall of the second ladder 43. By moving, it can engage or disengage with the L-shaped groove rod 451, thereby controlling the fixed or movable state of the second ladder 43. A sealing plate 453 is fixedly connected to the bottom of the limiting plate 454. The sealing plate 453 moves synchronously with the limiting plate 454. During the movement of the limiting plate 454, it can seal the sliding groove 452 on the inner wall of the first ladder 44 to prevent materials or impurities from entering the sliding groove 452 and affecting the sliding of the limiting plate 454.

[0026] Specifically, when stored, ladder 2 43 can be stably fixed to the outside of ladder 1 44. Its fixation is achieved by folding component 45, which includes an L-shaped groove rod 451. This rod cooperates with the limiting plate 454 through the groove to limit ladder 2 43. The structural design can achieve precise engagement, and its bottom is fixedly connected to the top of ladder 2 43. It can move synchronously with ladder 2 43 to ensure that the position always corresponds to the limiting plate 454. The limiting plate 454 is slidably connected to the inner wall of ladder 2 43. By moving up and down, it can engage or disengage with the L-shaped groove rod 451, thereby controlling the fixed and moving state of ladder 2 43. The bottom of the limiting plate 454 is fixedly connected to a sealing plate 453. The sealing plate 453 will move synchronously with the limiting plate 454. During the movement, it can seal the sliding groove 452 of the inner wall of ladder 1 44 to prevent materials or impurities from entering and affecting the sliding of the limiting plate 454.

[0027] The inner wall of the ladder 44 has a sliding groove 452, which provides a guide track for the sliding of the sealing plate 453, ensuring that the sealing plate 453 and the limiting plate 454 can only move in a fixed direction, avoiding deviation that could lead to limiting failure. The outer wall of the sealing plate 453 is slidably connected to the inner wall of the ladder 44. This sliding fit ensures that the sealing plate 453 can tightly fit against the inner wall of the ladder 44 when moving, improving the sealing effect and ensuring smooth movement. The inner wall of the sliding groove 452 further limits and guides the sealing plate 453, ensuring that the sealing plate 453 always moves along the track of the sliding groove 452 and preventing the sealing plate 453 from leaving the track. The inner wall of the L-shaped groove rod 451 is slidably and detachably connected to the limiting plate 454. The slidable and detachable connection allows the limiting plate 454 to slide into or out of the groove of the L-shaped groove rod 451. When it enters, it limits the L-shaped groove rod 451 and thus fixes the second ladder 43. When it leaves, it releases the limit and allows the second ladder 43 to rotate.

[0028] Specifically, the inner wall of ladder 44 has a sliding groove 452, which provides a guide track for the sliding of the sealing plate 453, ensuring that the sealing plate 453 and the limiting plate 454 move in a fixed direction and avoid limiting failure. It also further limits and guides the sealing plate 453 to prevent it from falling off the track. The outer wall of the sealing plate 453 is slidably connected to the inner wall of ladder 44, which improves the sealing effect through tight fit and ensures smooth movement. On the other hand, it is slidably connected to the inner wall of the sliding groove 452. In addition, the inner wall of the L-shaped groove rod 451 and the limiting plate 454 are slidably and detachably connected. When the limiting plate 454 slides into the groove, it can limit the L-shaped groove rod 451 and thus fix ladder 43. When the limiting plate 454 leaves the groove, the limiting is released, allowing ladder 43 to rotate.

[0029] The outer wall of the limiting plate 454 is slidably connected to the inner wall of the ladder 44. This slidable connection allows the limiting plate 454 to be supported and guided by the inner wall of the ladder 44 when it moves up and down, ensuring stability during the movement and preventing the limiting plate 454 from shaking. A return spring 455 is fixedly connected to the inner wall of the ladder 44. The return spring 455 provides the limiting plate 454 with the reset force. When the external force disappears, the return spring 455 can push the limiting plate 454 to move upward and re-engage with the L-shaped groove rod 451 to achieve the limit. Its fixed connection to the inner wall of the ladder 44 ensures that the spring position is stable and the direction of the elastic force is fixed. The top of the return spring 455 is fixedly connected to the bottom of the limiting plate 454. This connection method allows the elastic force of the return spring 455 to act directly on the limiting plate 454, ensuring that the limiting plate 454 is accurately reset under the action of the spring. Specifically, the outer wall of the limiting plate 454 is slidably connected to the inner wall of the ladder 44. The inner wall of the ladder 44 provides support and guidance for the up and down movement of the limiting plate 454, ensuring stable movement and preventing shaking. The inner wall of the ladder 44 is fixedly connected to the return spring 455, which provides the limiting plate 454 with the reset power. After the external force disappears, it can push the limiting plate 454 to move upward and re-engage with the L-shaped groove rod 451 to achieve the limit. The fixed connection method ensures that the spring position is stable and the elastic force direction is fixed. The top of the return spring 455 is fixedly connected to the bottom of the limiting plate 454, so that the elastic force can be directly applied to the limiting plate 454, ensuring that the limiting plate 454 is accurately reset.

[0030] Reference Figure 4 and Figure 5 The feeding mechanism 3 includes a motor 31, which provides a power source for the feeding mechanism 3. The motor 31 drives the stirring rod 32 to rotate by outputting torque, thereby driving the transmission components of the entire feeding mechanism 3. The driving end of the motor 31 is fixedly connected to the stirring rod 32 to ensure stable rotation of the stirring rod 32. The bottom of the stirring rod 32 is rotatably connected to the inside of the reaction vessel 1. The rotatable connection allows the stirring rod 32 to rotate freely under the drive of the motor 31. At the same time, the inside of the reaction vessel 1 provides stable support for the stirring rod 32 to prevent the stirring rod 32 from shaking during rotation. The top of the stirring rod 32 is fixedly connected to the first bevel gear 33. The fixed connection allows the rotation of the stirring rod 32 to synchronously drive the rotation of the first bevel gear 33, ensuring the timeliness and stability of power transmission.

[0031] Specifically, the feeding mechanism 3 includes a motor 31, which serves as the power source to drive the transmission components. The drive end of the motor 31 is fixedly connected to the stirring rod 32, ensuring complete torque transmission, preventing slippage, and guaranteeing stable rotation of the stirring rod 32. The bottom of the stirring rod 32 is rotatably connected to the inside of the reaction vessel 1, allowing it to rotate freely while providing stable support to prevent swaying. Furthermore, the top of the stirring rod 32 is fixedly connected to a first bevel gear 33, which synchronously transmits the rotation of the stirring rod 32 to the first bevel gear 33, ensuring timely and stable power transmission.

[0032] The first bevel gear 33, as a transmission component, changes the direction of power transmission, converting the vertical rotation of the stirring rod 32 into the lateral rotation of the second bevel gear 34. A stirring paddle 35 is rotatably connected to the inner wall of the protective box 5. This rotatable connection allows the stirring paddle 35 to rotate freely under the support of the inner wall of the protective box 5, thereby agitating the material entering the reactor 1. One end of the stirring paddle 35 is fixedly connected to the second bevel gear 34. This fixed connection ensures that the rotation of the second bevel gear 34 synchronously drives the stirring paddle 35 to rotate, providing sufficient torque for the stirring paddle 35 to agitate the material. The outer surfaces of the second bevel gear 34 and the first bevel gear 33 are meshed together. The key to power transmission is the interlocking of the teeth, which allows the rotation of the first bevel gear 33 to be precisely transmitted to the second bevel gear 34. This results in high transmission efficiency and low power loss. The outer wall of the reactor 1 is provided with a discharge port 2, which is the channel for the material to be discharged from the reactor 1 after the reaction is completed. The discharge port 2 is located on the outer wall of the reactor 1 to facilitate material collection and does not affect the operation of other components inside the reactor 1. The bottom of the motor 31 is fixedly connected to the top of the reactor 1. This fixed connection ensures that the motor 31 is stable at the top of the reactor 1 and prevents the motor 31 from shifting due to vibration during operation. This also ensures the stability of the connection between the drive end of the motor 31 and the stirring rod 32.

[0033] Specifically, the structure, connection method, and function of the power transmission component, stirring component, and discharge port 2 in the reactor 1 are as follows: The first bevel gear 33, as the transmission component, converts the vertical rotation of the stirring rod 32 into the lateral rotation of the second bevel gear 34, changing the direction of power transmission. The second bevel gear 34 is externally meshed with the first bevel gear 33, transmitting power through tooth meshing. One end of the second bevel gear 34 is fixedly connected to the stirring paddle 35, synchronously driving the stirring paddle 35 to rotate and providing sufficient torque. The stirring paddle 35 is rotatably connected to the inner wall of the protective box 5, allowing it to rotate freely under support to agitate materials. The outer wall of the reactor 1 has a discharge port 2, serving as a channel for discharging materials after the reaction, facilitating collection without affecting the operation of internal components. Furthermore, the bottom of the motor 31 is fixedly connected to the top of the reactor 1, ensuring the stability of the motor 31's position and preventing displacement due to vibration during operation, thereby ensuring the stability of the connection between its drive end and the stirring rod 32. Working principle: When it is necessary to inspect the inside of the reactor 1, first open the cover door 42. At this time, press the limiting plate 454. The pressing of the limiting plate 454 will drive the reset spring 455 to move downward. At this time, the limiting plate 454 will no longer be stuck in the groove of the L-shaped groove rod 451. Then the limiting plate 454 will no longer play a limiting role on the L-shaped groove rod 451. At this time, the second ladder 43 will no longer be fixed outside the first ladder 44. Rotating the second ladder 43 will lower the second ladder 43, making it easier for the staff to go down to the bottom of the reactor 1 to inspect the reactor 1. This avoids damage or incomplete cleaning of the inside of the reactor 1 due to incomplete inspection, which would affect the next use or make it difficult to maintain high efficiency in subsequent work.

[0034] When feeding material into the reactor 1, the material is added into the reactor 1 through the feed port 6. At this time, the motor 31 starts, which drives the stirring rod 32 to rotate. The rotation of the stirring rod 32 drives the first bevel gear 33 to rotate, which in turn drives the second bevel gear 34 to rotate. Through the transmission of the first bevel gear 33, the rotation of the second bevel gear 34 drives the stirring paddle 35 to rotate. Thus, during feeding, the stirring paddle 35 agitates the material, thereby preventing the material from accumulating inside the feed port 6 and causing blockages, which could lead to production stoppages and require manual removal of blockages, affecting work efficiency.
