Description

Technical Field

[0001] This invention relates to the field of heating reactor technology, and more specifically, to a layered heating reactor for resin processing. Background Technology

[0002] Layered heating reactors for resin processing are key temperature control devices in epoxy resin systems. Their design aims to achieve differentiated temperature control at different heights within the reactor through multiple independent heating zones in a vertical direction. In existing technologies, such reactors typically employ a multi-layered jacket structure or segmented heating plates arranged axially along the reactor body, supplemented by a stirring mechanism to promote heat convection and meet the phased thermal requirements of epoxy resin during synthesis and curing.

[0003] However, in actual operation, because the epoxy resin system exhibits a high-viscosity colloidal state in the later stages of gelation, even with stratified heating of the reactor wall, heat still cannot penetrate evenly to every micro-region within the colloid. Furthermore, some specialized epoxy formulations require catalytic initiation of a localized area at specific reaction stages. For instance, in the gradient curing of wind turbine blade main beams and the impregnation of carbon fiber composite cable cores, premature or delayed gelation in certain areas can lead to stress concentration and microscopic defects at the interface. Existing technologies often rely on stirring and dispersion or extending the holding time to alleviate this problem.

[0004] While stirring and dispersing can achieve a uniform distribution of the catalyst, it cannot avoid the problem of simultaneous activation across all temperature zones. This results in vertical discontinuities in the reaction progress of thick-walled products that originally required gradient curing. Although extending the holding time can slowly advance the gel interface through heat conduction, by this time the catalyst has already diffused evenly throughout the colloid. Operators cannot pause the reaction at a specific height to wait for mold filling, nor can they suppress catalytic activity in micro-regions where localized agglomeration has occurred to prevent defect propagation. As a result, the resin begins to gel before filling is complete, leading to frequent defects such as dry spots, bubbles, or interface debonding. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a layered heating reactor for resin processing, which aims to solve the above-mentioned technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A layered heating reactor for resin processing includes a reactor body and a sealing cover assembled at the top axial position of the reactor body. The sealing cover is equipped with a drive roller connected to a motor at its axial end. A temperature-regulating cavity layer is fixedly installed on the outer ring surface of the reactor body. A mixing cavity layer is installed inside the reactor body. The drive roller enters the interior of the mixing cavity layer, and a stirring part and a covered catalytic module fitted on the inlet end are provided.

[0008] A ring-driven temperature control module is movably disposed in the temperature-regulating cavity layer. The ring-driven temperature control module is magnetically attached to the covered catalytic module through the side wall of the mixing cavity layer. The ring-driven temperature control module is equipped with a liquid-cooled temperature control unit for cooling and a removable heating module for heating, so as to perform circumferential layered heating in accordance with the rotation of the stirring part.

[0009] The covered catalytic module includes a spray pipe for spraying catalyst from the top of the mixing cavity layer for catalysis, and a fixed-point catalytic module for local catalysis. The top of the mixing cavity layer is provided with an internally adsorbed storage ring for supplying the fixed-point catalytic module.

[0010] As a further aspect of the present invention: the ring-driven temperature control module includes a ring frame fixedly installed in the temperature-regulating cavity layer. Several liquid-cooled temperature control units are arranged equidistantly on the ring surface of the ring frame. Each liquid-cooled temperature control unit has a heat dissipation fin fixedly installed on its output end, facing the outer wall of the mixing cavity layer. Two liquid-cooled temperature control units are fixedly installed with series hoses at their bottoms. The removable heating module includes a hollow frame opened on the ring surface of the ring frame between two liquid-cooled temperature control units.

[0011] As a further aspect of the present invention: the removable heating module further includes a first circular sleeve fixedly installed at the top center of each hollow frame, and a gear sleeve is movably installed in each first circular sleeve. A first threaded rod perpendicular to the side wall of the circular frame is fixedly connected at the center of the surface of the gear sleeve.

A fitting frame that meshes with the first threaded rod is slidably installed on the first limiting rod. An electric heating temperature control unit is fixedly installed on each fitting frame. Several segmented heating tubes facing the mixing cavity layer are fixedly installed on the output end of the electric heating temperature control unit.

[0012] As a further aspect of the present invention: the removable heating module further includes an auxiliary ring frame movably installed on the top of the temperature-regulating cavity layer. The bottom of the auxiliary ring frame is fixedly connected to a toothed ring that meshes with each gear sleeve. Several first magnetic control heads are fixedly installed in a circumferentially equidistant arrangement on the inner ring surface of the auxiliary ring frame. The ring-driven temperature control module further includes an annular cover plate movably installed on the outer wall of the top of the mixing cavity layer. The inner wall of the annular cover plate is provided with a magnetic coating. A metal recessed annular groove is fixedly installed on the outer edge of the annular cover plate. The first magnetic control heads on the auxiliary ring frame are all embedded in the recesses of the metal recessed annular groove.

[0013] As a further aspect of the present invention: the removable heating module further includes two side wing plates arranged at 180 degrees and fixedly installed on the side of the annular cover plate. The side wing plates are placed between the outer wall of the mixing cavity layer and the heat dissipation fins. Each side wing plate has a vertically arranged limiting groove at the middle of its surface. A first servo motor is fixedly installed at the bottom of each limiting groove. A second threaded rod is fixedly installed on the output end of the first servo motor and is placed inside the limiting groove. An outer magnetic control sleeve plate corresponding to the second threaded rod is slidably installed in each limiting groove. The magnetic end of the outer magnetic control sleeve plate faces the mixing cavity layer. A magnetic drive motor is fixedly installed at the top side of the reactor body.

[0014] As a further aspect of the present invention: the stirring part includes a main stirring rod, the bottom of which is equipped with an electrically controlled magnetic connection fitting seat, and two horizontally symmetrically arranged auxiliary stirring rods are fixedly installed on the outside of the electrically controlled magnetic connection fitting seat. Each auxiliary stirring rod has a second limiting rod fixedly installed at its end, which is parallel to the main stirring rod. The outer surface of the inner suction storage ring is also provided with a magnetic coating, and the magnetic coating on the top of the mixing cavity layer corresponds to the magnetic coating on the inner wall of the annular cover plate. The side of the inner suction storage ring is connected to a liquid injection tube for replenishing reagents.

[0015] As a further aspect of the present invention: the covered catalytic module includes a second circular sleeve movably mounted on the surface of the main stirring rod. Two sets of symmetrically arranged first hinged sleeves are fixedly mounted on the outer edge surface of the second circular sleeve, and a spray pipe is hinged to each set of first hinged sleeves. A second hinged sleeve is fixedly mounted on the extended end of each spray pipe, and the second hinged sleeve is movably mounted on the second limiting rods on both sides of the main stirring rod. Horizontally arranged third limiting rods are fixedly mounted on both sides of the first hinged sleeve, and a circular patch integrally attached to the inner wall of the mixing cavity layer is fixedly mounted through four horizontally extended third limiting rods.

[0016] As a further aspect of the present invention: an inner magnetic control sleeve is fixedly installed on the side wall of the annular patch at the middle end of the two closely adjacent third limiting rods. The inner magnetic control sleeve is magnetically attracted to the outer magnetic control sleeve through the side wall of the mixing cavity layer. The fixed-point catalytic module includes a circular collar plate slidably installed on the two closely adjacent third limiting rods, and a sealing cavity block is fixedly installed on each circular collar plate. The sealing cavity block and the spray pipe are connected to a liquid supply hose communicating with the internal suction storage ring.

[0017] As a further aspect of the present invention: the fixed-point catalytic module further includes a liquid replenishment cavity fixedly installed at the top center of the sealed cavity block. An external drain conduit is fixedly installed on the top of the outer surface of the liquid replenishment cavity, and the external drain conduit communicates with the inner top of the liquid replenishment cavity. A bidirectional threaded rod is movably installed at the bottom center of the sealed cavity block. A negative pressure pusher that is slidably engaged with the bidirectional threaded rod and locked inside the liquid replenishment cavity is installed on the bidirectional threaded rod. A second magnetic control head is fixedly installed at the center of the surface of the outer magnetic control sleeve. The surface of the sealed cavity block is coated with a magnetic coating corresponding to the second magnetic control head.

[0018] As a further aspect of the present invention: the fixed-point catalytic module further includes a second servo motor fixedly installed at the middle position of the bottom of the sealed cavity block. A conical cover is fixedly installed on the output end of the second servo motor. The conical cover is attached to the inner bottom of the sealed cavity block, and a plurality of first valve ports are equidistantly opened on the bottom surface of the conical cover. A double-stirring spiral plate is fixedly installed on the top of the conical cover. A connecting sleeve connected to a bidirectional threaded rod is fixedly connected at the axial center of the double-stirring spiral plate. The double-stirring spiral plate is recessed between the liquid replenishment cavity and the second servo motor, and a plurality of second valve ports are equidistantly opened on the outer wall. A reserved circular opening is opened on the surface of the sealed cavity block at the positions of the first valve port and the second valve port.

[0019] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) This solution establishes a magnetic correspondence across the cavity wall between the ring-driven temperature control module and the covered catalytic module mounted on the stirring section, thereby enabling the external temperature control unit to move synchronously around the internal stirring and catalytic modules. This breaks the limitation of the separation between temperature control and catalytic functions in traditional reactors, allowing the liquid-cooled temperature control unit and the removable heating module to always maintain a positional correspondence with the internal covered catalytic module. When the covered catalytic module initiates catalysis in a local area, the ring-driven temperature control module can simultaneously apply temperature intervention to that area, achieving spatiotemporal coupling of dynamic temperature control and catalytic functions. Compared to the existing technology that relies on stirring and dispersion or extending the holding time to alleviate local overheating or uneven reaction progress, this solution can construct a temperature field matching the catalytic process inside the high-viscosity colloid, effectively suppressing interfacial stress concentration and microscopic defects caused by lag in heat conduction or global synchronous activation of the catalyst.

[0021] (2) The electric heating temperature control unit and its segmented heating tubes move radially relative to the outer wall of the mixing cavity layer through a linkage mechanism consisting of an auxiliary ring frame, a toothed ring, and a gear sleeve. When heating is required, the sleeve frame drives the heating tubes to extend towards the vessel wall, precisely applying heat to the designated area. When cooling or pausing heating is required, the heating tubes can be quickly withdrawn to the depth of the hollow frame, eliminating the thermal inertia effect that is difficult to avoid with traditional fixed heating elements. At the same time, the segmented heating tubes are arranged at intervals in the vertical direction and can be controlled independently, enabling differentiated heat output for different height positions of the mixing cavity layer. This solves the problem that heat is difficult to penetrate evenly into the micro-regions inside high-viscosity colloids in existing layered heating structures, providing a means of vertical temperature curve control for the gradient curing process of thick-walled resin products.

[0022] (3) By combining the internal and external magnetic attraction linkage mechanism with the fixed-point catalytic module, controllable micro-zone catalysis at any position inside the reactor can be achieved. The covered catalytic module is connected by the magnetic attraction between the inner and outer magnetic control plates. It can complete the precise adjustment of vertical lifting and circumferential rotation without penetrating the reactor wall. When the fixed-point catalytic module is moved to the target position, when the second servo motor drives the conical cover and the double stirring spiral plate to rotate, the first valve port is periodically aligned with the reserved circular port, so that local materials enter the sealed cavity block and are fully mixed with the catalyst injected through the external discharge conduit under the stirring action of the double stirring spiral plate. Then, it is discharged to the target area through the second valve port, so that the catalyst can act on the specific local reaction area in a micro-scale and controllable manner, avoiding the reaction progress discontinuity problem caused by the simultaneous activation of the catalyst in all temperature zones under the traditional global spray method.

[0042] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0043] The following is a detailed description of a layered heating reactor for resin processing provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; other alternative methods can be used by those skilled in the art for some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0044] like Figures 1 to 8 As shown, this embodiment of the invention provides a layered heating reactor for resin processing, including a reactor body 1 and a sealing cover 2 assembled at the top axial position of the reactor body 1. The sealing cover 2 is equipped with a drive roller 3 connected to a motor at its axial end. A temperature regulating cavity layer 4 is fixedly installed on the outer ring surface of the reactor body 1. A mixing cavity layer 5 is installed inside the reactor body 1. The drive roller 3 enters the interior of the mixing cavity layer 5, and a stirring part 8 and a covered catalytic module 9 fitted on the inlet end are provided.

[0045] A ring-driven temperature control module 6 is movably disposed in the temperature-regulating cavity layer 4. The ring-driven temperature control module 6 is magnetically connected to the covered catalytic module 9 through the side wall of the mixing cavity layer 5. The ring-driven temperature control module 6 is equipped with a liquid-cooled temperature control unit 62 for cooling and a removable heating module 65 for heating, so as to perform circumferential layered heating following the rotation of the stirring part 8.

[0046] The covered catalytic module 9 includes a spray pipe 93 for spraying catalyst from the top of the mixing cavity layer 5 for catalysis, and a fixed-point catalytic module 10 for local catalysis. The top of the mixing cavity layer 5 is provided with an internal absorption storage ring 7 for supplying the fixed-point catalytic module 10.

[0047] To address the technical problems of existing layered heating reactors for resin processing, which suffer from uneven heat penetration into the micro-regions of high-viscosity epoxy resin colloids and the inability to precisely catalyze localized areas at specific reaction stages, leading to frequent defects such as discontinuity in the gelation process, dry spots, bubbles, or interface debonding, the above-mentioned technical solution is adopted. This technical solution mainly consists of a reactor body 1, a sealing cover 2, a drive roller 3, a temperature-regulating cavity layer 4, a mixing cavity layer 5, a ring-driven temperature control module 6, an internal suction storage ring 7, a stirring section 8, and a covered catalytic module 9. The reactor body 1 is the main outer shell structure of the reactor in the prior art, made of high-strength corrosion-resistant metal material, and has a cylindrical shape. Its interior forms the main space for accommodating resin materials and carrying out the mixing reaction. The top opening is used to install the sealing cover 2 to form a sealed reaction environment. The sealing cover 2 is assembled at the top axial position of the reactor body 1, serving to seal the top opening of the reactor body. Simultaneously, its axial end serves as the mounting base for the drive roller 3. The drive roller 3 is connected to an external motor, which is a conventional motor assembled at the top of the reactor body, acting as the power input shaft. Its lower end passes through the sealing cover 2 and enters the interior of the mixing cavity layer 5, transmitting the motor's rotational power to the stirring section 8 and the covered catalytic module 9. The temperature-regulating cavity layer 4 is fixedly installed on the outer ring surface of the reactor body 1, forming an annular closed interlayer space surrounding the outer wall of the reactor body. The mixing cavity layer 5 is installed inside the reactor body 1, serving as a cavity structure for accommodating resin materials and carrying out mixing and reaction. Its sidewalls are made of materials with good thermal conductivity and magnetic permeability to facilitate heat transfer and magnetic penetration within the temperature-regulating cavity layer 4, enabling magnetic linkage between the inner and outer modules.

[0048] Specifically, the ring-driven temperature control module 6 is located inside the temperature-regulating cavity layer 4, with its overall position corresponding to the outer side wall of the mixing cavity layer 5. Through magnetic coupling, it establishes a magnetic attraction relationship with the internal covered catalytic module 9 across the side wall of the mixing cavity layer 5, thereby achieving contactless linkage between the inner and outer modules. The ring-driven temperature control module 6 integrates two temperature control units with different functions: a liquid-cooled temperature control unit 62 for cooling the mixing cavity layer 5, and a removable heating module 65 for heating the mixing cavity layer 5. During operation, the ring-driven temperature control module 6 can synchronously rotate around the stirring section 8, thereby performing layered heating and cooling control at different locations in the mixing cavity layer 5.

[0049] The covered catalytic module 9 is mounted on the stirring section 8 and rotates together with the stirring section 8 inside the mixing cavity layer 5. During operation, it can perform different catalytic processes depending on the specific conditions inside the reactor, including two catalytic modes. The first is the spray pipe 93, which sprays the catalyst from the top area of ​​the mixing cavity layer 5 downwards to the material, achieving a uniform and comprehensive distribution of the catalyst throughout the reaction space for large-area covered catalysis. The second is the targeted catalytic module 10, which is used to initiate targeted catalysis in a specific area within the mixing cavity layer 5 at a specific stage of the resin reaction to meet the special process requirements such as gradient curing. The internally aspirated storage ring 7 is installed on top of the mixing cavity layer 5 as a temporary catalyst storage and supply transfer station. It stores liquid catalyst and is connected to the spray pipe 93 and the targeted catalytic module 10 through a liquid supply pipeline to supply catalyst to both in a targeted manner.

[0050] During operation, the ring-driven temperature control module 6 outside the reactor body 1 and the covered catalytic module 9 inside, which rotates with the stirring part 8, achieve cross-cavity wall linkage control through magnetic attraction. This ensures that the liquid-cooled temperature control unit 62 and the removable heating module 65 always maintain positional correspondence with the covered catalytic module 9 inside. Thus, while the catalytic reaction is underway, synchronous temperature intervention can be achieved in this local area. This integrates dynamic temperature control and catalytic function. Driven by the stirring part 8, it achieves differentiated thermal management and catalytic management of different spatial locations in the reactor over time. This solves the problems of lag in heat conduction inside high-viscosity colloids and the inability to gradient solidify due to global synchronous activation of the catalyst. It also suppresses stress concentration and microscopic defects at the interface caused by discontinuity in the reaction progress.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the ring-driven temperature control module 6 includes a ring frame 61 fixedly installed in the temperature-regulating cavity layer 4. Several liquid-cooled temperature control units 62 are arranged equidistantly on the ring surface of the ring frame 61. Each liquid-cooled temperature control unit 62 has a heat dissipation fin 63 fixedly installed on its output end, facing the outer wall of the mixing cavity layer 5. Each liquid-cooled temperature control unit 62 has a series flexible hose 64 fixedly installed at its bottom. The removable heating module 65 includes a hollow frame 651 opened on the ring surface of the ring frame 61 between two liquid-cooled temperature control units 62.

[0052] The configured ring-driven temperature control module 6 mainly consists of a ring frame 61, a liquid-cooled temperature control unit 62, heat dissipation fins 63, a series hose 64, and a hollow frame 651 for a removable heating module 65. The ring frame 61 is the overall supporting skeleton of the ring-driven temperature control module 6, made of high-strength lightweight metal material, and has a ring-shaped configuration. Its outer diameter is adapted to the inner diameter of the temperature-regulating cavity layer 4. Each liquid-cooled temperature control unit 62 is a miniature liquid-cooled heat exchange component in the prior art. It has a circulation channel for the cooling medium to flow through. The coolant is driven by an external circulation pump to flow through its interior, realizing the heat absorption and cooling function of the flow area. On the output end of each liquid-cooled temperature control unit 62, that is, on the side facing the outer wall of the mixing cavity layer 5, there are fixed... A heat dissipation fin 63 is fixedly installed. The heat dissipation fin 63 is made of a material with a high thermal conductivity and has a fin-like structure. Its tip extends towards the outer wall of the mixing cavity layer 5. It is used to quickly conduct heat absorbed by the liquid-cooled temperature control unit 62 from the side wall of the mixing cavity layer 5 and dissipate it into the internal space of the temperature-regulating cavity layer 4 to help improve the cooling effect. At the same time, a series hose 64 is fixedly installed at the bottom of two adjacent liquid-cooled temperature control units 62. All liquid-cooled temperature control units 62 on the annular frame 61 are connected in series in a predetermined order through several series hoses 64 to form a complete coolant circulation path, so that the external coolant can flow through each liquid-cooled temperature control unit 62 in sequence, realizing unified liquid supply and circulation cooling of all liquid-cooled temperature control units 62. The configured removable heating module 65 includes a hollow frame 651, which is opened on the annular surface of the circular frame 61, specifically at the interval between two adjacent liquid-cooled temperature control units 62. Each hollow frame 651 is a through hole structure that penetrates the inner and outer sides of the circular frame 61, and its internal space is used to accommodate and install other components of the removable heating module 65.

[0053] During operation, the liquid cooling temperature control unit 62 is integrated onto the circular frame 61 that can rotate, and all liquid cooling temperature control units 62 are connected in series to form a unified circulation path using a series hose 64, so that the cooling end can be easily and uniformly controlled, thereby improving the targeting and uniformity of cooling.

[0054] like Figure 3 , Figure 4, Figure 5 , Figure 6 As shown, the removable heating module 65 further includes a first circular sleeve 652 fixedly installed at the top center of each hollow frame 651, and a gear sleeve 653 is movably installed in each first circular sleeve 652. A first threaded rod 654 perpendicular to the side wall of the circular frame 61 is fixedly connected at the center of the surface of the gear sleeve 653. A first limiting rod 655 flush with the first threaded rod 654 is fixedly installed at the bottom center of each hollow frame 651. A fitting frame 656 that meshes with the first threaded rod 654 is slidably installed on the first limiting rod 655. An electric heating temperature control unit 657 is fixedly installed on each fitting frame 656. Several segmented heating tubes 658 facing the mixing cavity layer 5 are fixedly installed on the output end of the electric heating temperature control unit 657.

[0055] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the removable heating module 65 also includes an auxiliary ring frame 659 movably mounted on the top of the temperature-regulating cavity layer 4. The bottom of the auxiliary ring frame 659 is fixedly connected to a toothed ring 6510 that meshes with each gear sleeve 653. Several first magnetic control heads 6511 are fixedly mounted in a circumferentially equidistant arrangement on the inner ring surface of the auxiliary ring frame 659. The ring-driven temperature control module 6 also includes an annular cover plate 66 movably mounted on the outer wall of the top of the mixing cavity layer 5. The inner wall of the annular cover plate 66 is provided with a magnetic coating. A metal recessed annular groove 67 is fixedly mounted on the outer edge of the annular cover plate 66. The first magnetic control heads 6511 on the auxiliary ring frame 659 are all embedded in the recesses of the metal recessed annular groove 67.

[0056] In existing heated reactors, heating elements are typically fixedly installed on the reactor wall or inside the jacket. Once heating is started, they continuously radiate heat into the reactor, making it impossible to quickly remove the heat source according to process requirements. This results in residual thermal inertia continuing to act on the reactants when emergency cooling or prevention of local overheating is needed, exacerbating the risk of localized agglomeration. The removable heating module 65 mainly consists of a first circular sleeve 652, a gear sleeve 653, a first threaded rod 654, a first limiting rod 655, a fitting frame 656, an electric heating temperature control unit 657, a segmented heating tube 658, an auxiliary circular frame 659, a toothed ring 6510, a first magnetic control head 6511, a circular cover plate 66, and a metal concave... The ring groove 67 is composed of a first circular sleeve 652 fixedly installed at the top center of each hollow frame 651, serving as a rotating support base for accommodating and positioning the gear sleeve 653. The gear sleeve 653 is movably installed inside the first circular sleeve 652, and its outer circumferential surface is provided with gear teeth, which can rotate relative to the first circular sleeve 652. At the same time, a first threaded rod 654 is fixedly connected at the center of its surface. The first threaded rod 654 extends horizontally perpendicular to the side wall of the ring frame 61 toward the mixing cavity layer 5. The first limiting rod 655 extends in the same direction as the first threaded rod 654 and has a length equivalent to it, serving as a guide and limiting element. The configured fitting frame 656 is slidably mounted on the first limiting rod 655, and the fitting frame 656 has an internal thread structure that meshes with the first threaded rod 654. When the first threaded rod 654 rotates, it can drive the fitting frame 656 to slide smoothly in a straight line along the axial direction of the first limiting rod 655. Each fitting frame 656 is fixedly mounted with an electric heating temperature control unit 657. The electric heating temperature control unit 657 is an electric heating component in the prior art. It integrates a temperature sensor and a power adjustment module and can accurately adjust the heating power according to the received control signal. At the output end of the electric heating temperature control unit 657, that is, on the side facing the mixing cavity layer 5, several segmented heating tubes 658 are fixedly mounted. These segmented heating tubes 658 are arranged at certain intervals in the vertical direction. Each heating tube can independently control the heating state, so that differentiated heating intervention can be performed for different height positions of the mixing cavity layer 5.

[0057] Furthermore, the auxiliary ring frame 659 is movably installed on the top of the temperature-regulating cavity layer 4, and has an overall ring-shaped configuration. It can rotate relative to the temperature-regulating cavity layer 4. At the bottom of the auxiliary ring frame 659, a toothed ring 6510 is fixedly connected. The inner or outer ring of the toothed ring 6510 has a continuous tooth structure and maintains a meshing relationship with the gear sleeve 653 on the top of each hollow frame 651, forming a circumferentially linked gear transmission system. On the inner ring surface of the auxiliary ring frame 659, a plurality of first magnetic control heads 6511 are fixedly installed in a circumferentially equidistant arrangement. The first magnetic control head 6511 is a magnetic assembly that can be electrically controlled in the prior art, used to generate magnetic forces of different magnitudes and to open and close the magnetic suction end. At the same time, a circular annular cover plate 66 is movably installed at the top outer wall of the mixing cavity layer 5. The circular annular cover plate 66 can rotate relative to the mixing cavity layer 5, and its inner wall is provided with a magnetic suction coating for establishing a magnetic suction connection with the inner suction storage ring 7. A metal notch groove 67 is fixedly installed on the outer edge of the annular cover plate 66. The outer circumferential surface of the metal notch groove 67 has notches corresponding to the number and position of the first magnetic control heads 6511. The first magnetic control heads 6511 on the auxiliary annular frame 659 are respectively embedded in these notches. The magnetic attraction of the first magnetic control heads 6511 realizes the temporary magnetic connection between the auxiliary annular frame 659 and the annular cover plate 66 and the cancellation of the magnetic connection state, so as to realize the subsequent contactless linkage.

[0058] During operation, the magnetic drive motor 11 drives the annular cover plate 66 to rotate. The output end of the first magnetic control head 6511 is attracted to the inside of the metal notch groove 67, so that the annular cover plate 66 and the auxiliary annular frame 659 temporarily form an integrated structure. The rotation of the annular cover plate 66 can drive the auxiliary annular frame 659 to rotate in the same direction on the top of the temperature regulating cavity layer 4. The rotation of the auxiliary annular frame 659 further drives each meshing gear sleeve 653 to rotate in the first circular sleeve 652 through the toothed ring 6510 at its bottom. The rotation of the gear sleeve 653 drives the first threaded rod 654 fixedly connected to it to rotate synchronously, thereby driving the fitting frame 656 meshing with the first threaded rod 654 to move radially in a straight line along the first limit rod 655. When heating is required, the rotation direction of the annular cover plate 66 is controlled, causing the fitting frame 656 to extend towards the mixing cavity layer 5. This moves the electric heating temperature control unit 657 and its segmented heating tube 658 to a working position close to the outer wall of the mixing cavity layer 5. At this time, the electric heating temperature control unit 657 is activated, and heat is transferred into the vessel through the segmented heating tube 658. When cooling or pausing heating is required, the rotation of the annular cover plate 66 is controlled in the opposite direction, causing the fitting frame 656 to retract away from the mixing cavity layer 5. This removes the electric heating temperature control unit 657 and its heating tube deep into the hollow frame 651, away from the vessel wall, eliminating the continuous radiation of heat source to the material, and creating stable environmental conditions for the subsequent liquid cooling temperature control unit 62 to perform rapid cooling and local catalysis.

[0059] The retractable heating module 65 achieves dynamic, retractable control of the heating element, enabling the heat source to quickly move closer to or further away from the reactor inner cylinder according to process requirements. This allows for precise application of heat when needed and rapid removal of the heat source when cooling or overheating prevention is required. This eliminates the thermal inertia problem inherent in traditional fixed heating structures, enhancing the reactor's rapid response to localized overheating risks and its ability to suppress temperature fluctuations. Furthermore, by installing several independently controllable segmented heating tubes 658, independent, segmented heating of different height positions in the mixing cavity layer 5 is achieved. This avoids reaction progress interruptions caused by uneven temperature distribution in the vertical direction, according to the resin gradient curing process requirements.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the removable heating module 65 also includes two side wing plates 68 fixedly installed at the side of the annular cover plate 66 and arranged at 180 degrees. The side wing plates 68 are placed between the outer wall of the mixing cavity layer 5 and the heat dissipation fins 63. Each side wing plate 68 has a vertically arranged limiting groove 69 at the middle of its surface. A first servo motor 610 is fixedly installed at the bottom of each limiting groove 69. A second threaded rod 611, which is placed inside the limiting groove 69, is fixedly installed on the output end of the first servo motor 610. An outer magnetic control sleeve plate 612, which meshes with the second threaded rod 611, is slidably installed in each limiting groove 69. The magnetic end of the outer magnetic control sleeve plate 612 faces the mixing cavity layer 5. A magnetic drive motor 11 is fixedly installed at the top side of the reactor body 1.

[0061] To address the challenges of fixed-position catalytic modules in existing layered heating reactors for processing high-viscosity resins, which cannot dynamically adjust their contact with materials according to the reaction progress and result in uniform global catalyst distribution, hindering precise intervention in localized reaction areas, and the need for traditional mechanical transmission structures to penetrate the reactor wall when catalyzing specific layers, posing leakage risks and sealing difficulties, the aforementioned technical solution addresses these issues. The removable heating module 65 in this solution also includes a fixed mounting on the side of the annular cover plate 66. The device consists of a side wing plate 68, a first servo motor 610, a second threaded rod 611, and an outer magnetic control sleeve plate 612. The side wing plate 68 consists of two pieces, which are fixedly installed at the side of the annular cover plate 66 at a 180-degree angle. The whole is placed in the annular gap between the outer wall of the mixing cavity layer 5 and the heat dissipation fins 63. Each side wing plate 68 is a plate-shaped structure extending in the vertical direction. A vertically arranged limiting groove 69 is opened in the middle of its surface. The limiting groove 69 is a guide groove that runs through in the vertical direction and is used to accommodate and guide the outer magnetic control sleeve plate 612 to slide vertically. At the bottom of each limiting groove 69, a first servo motor 610 is fixedly installed. This first servo motor 610 is a micro servo motor in the prior art. Its output end is fixedly installed with a second threaded rod 611 integrally placed inside the limiting groove 69. The axis of the second threaded rod 611 is parallel to the extension direction of the limiting groove 69, and it can rotate precisely in both directions under the drive of the first servo motor 610. In the limiting groove 69, an outer magnetic control sleeve 612 is slidably installed. The outer magnetic control sleeve 612 has an internal thread structure that meshes with the second threaded rod 611. When the second threaded rod 611 rotates, it can drive the outer magnetic control sleeve 612 to slide smoothly vertically up and down in a straight line along the limiting groove 69. The magnetic end of the outer magnetic control sleeve 612 faces the mixing cavity layer 5. That is, an electromagnet assembly in the prior art that can change the magnetic state by electronic control is embedded on its end face facing the outer wall of the mixing cavity layer 5. The configured magnetic drive motor 11 is a servo-controlled motor device capable of magnetic drive in the prior art. Its output end acts on the annular cover plate 66 through the reactor body 1 to adsorb and control the annular cover plate 66 to perform circumferential servo drive.

[0062] During operation, when it is necessary to adjust the magnetically corresponding position with the internal covered catalytic module 9, the output end of the first servo motor 610 drives the second threaded rod 611 to rotate, thereby driving the outer magnetic control sleeve 612 to rise or fall along the limiting groove 69 to the preset vertical height position. Since the magnetic end of the outer magnetic control sleeve 612 maintains a magnetically corresponding relationship with the inner magnetic control sleeve 97 on the internal covered catalytic module 9 through the side wall of the mixing cavity layer 5, by controlling the vertical position of the outer magnetic control sleeve 612, the inner magnetic control sleeve 97 and its connected fixed-point catalytic module 10 can be pulled synchronously to the required vertical height without contact, realizing the dynamic adjustment of the catalytic action position. This achieves contactless magnetic coupling transmission between the external drive unit and the internal execution unit, avoiding the risk of media leakage and the problem of complicated sealing structure caused by the transmission shaft penetrating the vessel wall, and improving the operational safety and reliability of the reactor under high pressure, high viscosity or volatile media conditions. Meanwhile, by driving the outer magnetic control plate 612 to slide in the vertical direction through the first servo motor 610, the height position of the internal fixed-point catalytic module 10 in the mixing cavity layer 5 can be adjusted in real time according to the process requirements of resin gradient curing. This allows the catalyst to act precisely on the specific local area where the reaction is taking place, avoiding global diffusion and synchronous activation of the catalyst, and realizing on-demand fixed-point catalysis.

[0063] like Figure 3 , Figure 4 , Figure 7 As shown, the stirring unit 8 includes a main stirring rod 81. An electrically controlled magnetic coupling seat 82 is installed at the bottom of the main stirring rod 81. Two horizontally symmetrical auxiliary stirring rods 83 are fixedly installed on the outside of the electrically controlled magnetic coupling seat 82. Each auxiliary stirring rod 83 has a second limiting rod 84 fixedly installed at its end, which is parallel to the main stirring rod 81. The outer surface of the inner suction storage ring 7 is also provided with a magnetic coating. The magnetic coating on the top of the mixing cavity layer 5 is adsorbed and corresponds to the magnetic coating on the inner wall of the annular cover plate 66. The side of the inner suction storage ring 7 is connected to a liquid injection tube for replenishing reagents.

[0064] The main stirring rod 81 is the central rotating shaft of the stirring part 8. Its upper end is fixedly connected to the drive roller 3 and is driven to rotate by the drive roller 3. The main stirring rod 81 extends vertically into the interior of the mixing cavity layer 5. An electrically controlled magnetic coupling seat 82 is installed at the bottom of the main stirring rod 81. This electrically controlled magnetic coupling seat 82 is a base structure in the prior art that is connected by an electrically controlled magnetic coupling head. Its coupling end is controlled by an electrically controlled magnetic device to adjust the connection state of its coupling end in real time. When the magnetic end is working, the electrically controlled magnetic coupling seat 82 can be integrated into one piece under the action of magnetic attraction. At this time, the rotation of the main stirring rod 81 can drive the rotation of the two auxiliary stirring rods 83. When the magnetic end is not working, the magnetic attraction disappears, and the two auxiliary stirring rods 83 are in a movable state relative to the bottom of the main stirring rod 81. In this state, the cover-type catalytic module 9 configured on the two auxiliary stirring rods 83 is equivalent to being separated from the main stirring rod 81 and does not rotate with the rotation of the main stirring rod 81, so as to facilitate the rotation of the annular cover plate 66 and avoid motion interference. Two auxiliary stirring rods 83 on the electrically controlled magnetic connection fitting seat 82 are arranged horizontally symmetrically, that is, they extend horizontally in opposite directions to form a paddle-type stirring structure, which is used to fully mix and stir the resin material in the mixing cavity layer 5 during rotation. At the end of each auxiliary stirring rod 83, a second limiting rod 84 is fixedly installed. The axis of the second limiting rod 84 is parallel to the axis of the main stirring rod 81, that is, it extends in the vertical direction. Its function is to provide sliding guidance and limiting support for the subsequently installed covered catalytic module 9.

[0065] The configured internal suction storage ring 7 is a hollow annular structure, movably installed at the top inner position of the mixing cavity layer 5. Its interior forms a cavity for storing liquid catalyst. A magnetic coating is also disposed on the outer surface of the internal suction storage ring 7. This magnetic coating, separated by the inner top sidewall of the mixing cavity layer 5, forms a magnetic attraction relationship with the magnetic coating on the inner wall of the annular cover plate 66 located at the outer top sidewall of the mixing cavity layer 5. Through magnetic coupling, the internal suction storage ring 7 and the annular cover plate 66 achieve non-contact adsorption linkage. When the magnetic drive motor 11 rotates at the same frequency as the motor at one end of the drive roller 3, the internal suction storage ring 7 and the stirring part 8 can be controlled to maintain the same rotation state during rotation to ensure the stability of the liquid injection tube for delivering reagents. On the side of the internal storage ring 7, there is a liquid injection tube for replenishing reagents. The liquid injection tube extends to the outside through the reactor body 1 and the temperature control cavity layer 4, and is used to replenish fresh catalyst or reaction reagents into the internal storage ring 7 from the outside without opening the sealing cap 2.

[0066] During operation, the drive roller 3 rotates the main stirring rod 81, which in turn drives two auxiliary stirring rods 83 in a circular motion via an electrically controlled magnetically connected fitting seat 82, efficiently mixing the resin material within the mixing cavity layer 5. Simultaneously, because the internal suction storage ring 7 is magnetically attached to the annular cover plate 66, and the annular cover plate 66 rotates synchronously via a magnetic drive motor 11, the external temperature control module can always follow the position of the internal stirring and catalytic modules to intervene in temperature control, providing a structural basis for precise control of local reactions.

[0067] like Figure 3 , Figure 4 , Figure 7 As shown, the covered catalytic module 9 includes a second round sleeve 91 movably mounted on the surface of the main stirring rod 81. Two sets of symmetrically arranged first hinge sleeves 92 are fixedly mounted on the outer edge surface of the second round sleeve 91, and a spray pipe 93 is hinged to each set of first hinge sleeves 92. A second hinge sleeve 94 is fixedly mounted on the extended end of each spray pipe 93, and the second hinge sleeve 94 is movably fitted onto the second limiting rods 84 on both sides of the main stirring rod 81. A third limiting rod 95 arranged horizontally is fixedly mounted on both sides of the first hinge sleeve 92, and a circular patch 96 integrally attached to the inner wall of the mixing cavity layer 5 is fixedly mounted through the four horizontally extended third limiting rods 95.

[0068] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, an inner magnetic control sleeve 97 is fixedly installed on the side wall of the annular patch 96 at the middle end of the two closely adjacent third limiting rods 95. The inner magnetic control sleeve 97 is magnetically attracted to the outer magnetic control sleeve 612 through the side wall of the mixing cavity layer 5. The fixed-point catalytic module 10 includes a circular collar plate 102 slidably installed on the two closely adjacent third limiting rods 95, and a sealing cavity block 101 is fixedly installed on each circular collar plate 102. The sealing cavity block 101 and the spray pipe 93 are connected to a liquid supply hose that communicates with the internal suction storage ring 7.

[0069] The second circular sleeve 91 is movably mounted on the surface of the main stirring rod 81 and can slide along the axial direction of the main stirring rod 81, serving as the overall mounting base for the covered catalyst module 9. Two sets of symmetrically arranged first hinged sleeves 92 are fixedly mounted on the outer edge surface of the second circular sleeve 91. Each set of first hinged sleeves 92 is hinged with a spray pipe 93, which is a hollow tubular structure with multiple spray holes on its wall for spraying catalyst onto the material below. At the extended end of each spray pipe 93, i.e., the end furthest from the first hinged sleeve 92, a second hinged sleeve 94 is fixedly mounted. This second hinged sleeve 94 is movably fitted onto the second limiting rods 84 on both sides of the main stirring rod 81, so that the end of the spray pipe 93 is constrained and guided by the second limiting rods 84. On both sides of the first hinge sleeve 92, horizontally arranged third limiting rods 95 are fixedly installed. These third limiting rods 95 extend outward in the horizontal direction. A circular patch 96 is fixedly installed through the four horizontally extended third limiting rods 95. The circular patch 96 is attached to the inner wall of the mixing cavity layer 5 and can slide vertically and rotate along the inner wall to provide guidance and stable support for the overall movement of the covered catalytic module 9.

[0070] On the annular patch 96, specifically at the side wall position between the two closely adjacent third limiting rods 95, an inner magnetic control sleeve 97 is fixedly installed. The inner magnetic control sleeve 97 is a plate-shaped structure with an embedded electromagnet. It maintains a magnetic attraction relationship with the outer magnetic control sleeve 612 on the outer side wing plate 68 through the side wall of the mixing cavity layer 5, and realizes contactless linkage between the inner and outer modules through magnetic coupling. The configured fixed-point catalytic module 10 includes a circular collar plate 102 slidably installed on the two closely adjacent third limiting rods 95. The circular collar plate 102 can slide vertically along the third limiting rods 95. On each circular collar plate 102, a sealing cavity block 101 is fixedly installed. The sealing cavity block 101 is a hollow sealed cavity used to release the catalyst. Both the sealed chamber block 101 and the spray pipe 93 are connected to a liquid supply hose that communicates with the internal suction storage ring 7, for obtaining the catalyst from the internal suction storage ring 7.

[0071] During operation, the cooperative motion mechanism of the covered catalytic module 9 is as follows:

[0072] In the initial state or during global mixing, the electrically controlled magnetic coupling seat 82 is in a magnetically engaged state, fixing the auxiliary stirring rods 83 on both sides to the main stirring rod 81 as one unit. At this time, the drive roller 3 drives the main stirring rod 81 to rotate, which in turn drives the auxiliary stirring rods 83 and the second limiting rod 84 to rotate together through the electrically controlled magnetic coupling seat 82. Since the spray pipe 93 of the covered catalyst module 9 is movably sleeved on the second limiting rod 84 through the second hinge sleeve 94, and the annular patch 96 is attached to the inner wall of the mixing cavity layer 5, the entire covered catalyst module 9 rotates synchronously with the rotation of the stirring part 8, realizing the all-round uniform spraying of the catalyst.

[0073] When adjusting the vertical position of the covered catalytic module 9, the external first servo motor 610 first drives the outer magnetic control sleeve 612 to rise or fall along the limiting groove 69 to the preset height. Since the outer magnetic control sleeve 612 and the inner magnetic control sleeve 97 are magnetically attracted to each other through the side wall of the mixing cavity layer 5, the vertical movement of the outer magnetic control sleeve 612 will cause the inner magnetic control sleeve 97 and its fixedly connected annular patch 96 to move synchronously through magnetic force. The movement of the annular patch 96 drives the second circular sleeve 91 and the entire covered catalytic module 9 to slide vertically along the main stirring rod 81 and the second limiting rod 84 through the third limiting rod 95, thereby raising or lowering the entire covered catalytic module 9 to the required vertical height. After the vertical position adjustment is completed, the first magnetic control head 6511 on the auxiliary ring frame 659 is disconnected from the magnetic connection with the metal notch 67 on the annular cover plate 66, so that the auxiliary ring frame 659 and the annular cover plate 66 are disengaged from the transmission relationship, ensuring that the heating module remains stable during the subsequent stirring process and does not need to be adjusted forward or backward.

[0074] When targeted catalysis is required, the rotation of the drive roller 3 is first stopped, causing the main stirring rod 81 to stop rotating. Then, the electrically controlled magnetic coupling seat 82 cancels the magnetic engagement, disengaging the auxiliary stirring rod 83 from the main stirring rod 81. At this time, the covered catalytic module 9 is no longer constrained by the rotation of the stirring part 8, and is only linked to the outside through the magnetic connection between the inner magnetic control sleeve 97 and the outer magnetic control sleeve 612. Then, the magnetic drive motor 11 is started, driving the annular cover plate 66 to rotate through magnetic force. Since the outer magnetic control sleeve 612 is fixed to the side wing plate 68, and the side wing plate 68 is fixed to the annular cover plate 66, the rotation of the annular cover plate 66 will drive the entire covered catalytic module 9 to rotate circumferentially through the magnetic connection between the outer magnetic control sleeve 612 and the inner magnetic control sleeve 97, thereby adjusting the targeted catalytic module 10 to the required circumferential position. Simultaneously, the first servo motor 610 drives the outer magnetic control sleeve 612 to move vertically, allowing the fixed-point catalytic module 10 to slide vertically along the third limiting rod 95 to the desired height position via magnetic attraction. Through the combined adjustment of the circumferential and vertical directions, the fixed-point catalytic module 10 can be precisely moved to any three-dimensional spatial position within the mixing cavity layer 5, achieving precise catalysis of the local reaction area. By adopting the structure of the covered catalytic module 9, dual-mode synergy of catalytic functions can be achieved during operation. The spray pipe 93 provides global coverage catalysis, while the fixed-point catalytic module 10 provides localized precise catalysis, and the two can be flexibly switched according to process requirements.

[0075] Through the internal and external magnetic linkage mechanism, the internal catalytic module can be precisely controlled to move vertically and rotate circumferentially without opening the lid or penetrating the vessel wall. This avoids the leakage risk and sealing problems of traditional mechanical transmission structures. During fixed-point catalysis, the separation of the electrically controlled magnetic connection fitting seat 82 allows the covered catalytic module 9 to move independently of the stirring part 8. At the same time, the detachment of the first magnetic control head 6511 ensures that the heating module remains stable during catalytic adjustment and does not interfere with the temperature field, thus decoupling the catalytic position adjustment from the temperature control and stirring functions.

[0076] like Figure 3 , Figure 4 , Figure 7 , Figure 8As shown, the fixed-point catalytic module 10 also includes a liquid replenishment cavity 103 fixedly installed at the top center of the sealed cavity block 101. An external drain conduit 104 is fixedly installed on the top of the outer surface of the liquid replenishment cavity 103, and the external drain conduit 104 communicates with the top of the inner surface of the liquid replenishment cavity 103. A bidirectional threaded rod 1012 is movably installed at the bottom center of the sealed cavity block 101. A negative pressure push block 1013 is engaged with the bidirectional threaded rod 1012 and slidably locked inside the liquid replenishment cavity 103. A second magnetic control head 613 is fixedly installed at the center of the surface of the outer magnetic control sleeve plate 612. The surface of the sealed cavity block 101 is coated with a magnetic coating corresponding to the second magnetic control head 613.

[0077] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the fixed-point catalytic module 10 also includes a second servo motor 106 fixedly installed at the middle position of the bottom of the sealed cavity block 101. A conical cover 107 is fixedly installed on the output end of the second servo motor 106. The conical cover 107 is attached to the inner bottom of the sealed cavity block 101, and a plurality of first valve ports 108 are equidistantly opened on the bottom surface of the conical cover 107. A double-stirring spiral plate 109 is fixedly installed on the top of the conical cover 107. A connecting sleeve 1011 connected to the bidirectional threaded rod 1012 is fixedly connected at the axial center position of the double-stirring spiral plate 109. The double-stirring spiral plate 109 is recessed between the liquid replenishment cavity 103 and the second servo motor 106, and a plurality of second valve ports 1010 are equidistantly opened on the outer side wall. A reserved circular opening 105 is opened at the positions of the first valve ports 108 and the second valve ports 1010 on the surface of the sealed cavity block 101.

[0078] The liquid replenishment cavity 103 is fixedly installed at the middle position of the inner top of the sealed cavity block 101. It is an independent sealed cavity used to pre-store the catalyst to be added. An external discharge conduit 104 is fixedly installed on the top of the outer surface of the liquid replenishment cavity 103. One end of the external discharge conduit 104 is connected to the inner top of the liquid replenishment cavity 103, and the other end extends to the outside of the sealed cavity block 101. It is used to accurately discharge the catalyst stored in the liquid replenishment cavity 103 into the inner cavity of the sealed cavity block 101 when needed. At the middle of the inner bottom of the sealed cavity block 101, a bidirectional threaded rod 1012 is movably installed. The surface of the bidirectional threaded rod 1012 has bidirectional threads, which can drive the meshing parts to reciprocate linear motion when rotated. A negative pressure pusher 1013 is meshed on the bidirectional threaded rod 1012. The negative pressure pusher 1013 is slidably locked inside the replenishment cavity 103, and its outer edge is sealed with the inner wall of the replenishment cavity 103. When the bidirectional threaded rod 1012 rotates, the negative pressure pusher 1013 can move up and down reciprocally inside the replenishment cavity 103, similar to a syringe piston, thereby generating negative or positive pressure in the replenishment cavity 103 to realize the absorption and discharge of the catalyst. In order to ensure the stability of the absorption and discharge of the catalyst, a corresponding one-way valve head is configured on the absorption and discharge end of the replenishment cavity 103 to prevent backflow.

[0079] A second magnetic control head 613 is fixedly installed at the middle position of the surface of the outer magnetic control sleeve plate 612. The second magnetic control head 613 is an electrically controllable magnet assembly in the prior art, which can also generate or eliminate magnetic force according to the control signal. Correspondingly, a magnetic attraction coating corresponding to the second magnetic control head 613 is coated on the surface of the sealing cavity block 101, so that the sealing cavity block 101 can establish a magnetic attraction correspondence with the second magnetic control head 613. It should be noted that the magnetic control of the second magnetic control head 613 is independent of and operates in a time-sharing manner from the magnetic control of the first magnetic control head 6511 and the outer magnetic control sleeve 612, in order to avoid motion interference. When the covered catalytic module 9 is adjusted vertically or rotates synchronously with the stirring part 8, the second magnetic control head 613 is in a demagnetized state, ensuring that the fixed-point catalytic module 10 is positioned only through the magnetic attraction connection between the inner magnetic control sleeve 97 and the outer magnetic control sleeve 612. When the fixed-point catalytic function needs to be activated, the second magnetic control head 613 is energized to generate magnetic force, which attracts the magnetic coating on the surface of the sealing cavity block 101, keeping the sealing cavity block 101 and the second magnetic control head 613 relatively fixed. At the same time, the magnetic attraction connection between the outer magnetic control sleeve 612 and the inner magnetic control sleeve 97 can be appropriately weakened or maintained. However, through the auxiliary positioning of the second magnetic control head 613, the fixed-point catalytic module 10 is ensured to be stable in position during the catalytic process and is not affected by external disturbances.

[0080] A second servo motor 106 is fixedly installed at the center of the inner bottom of the sealed cavity block 101. The output end of the second servo motor 106 faces upwards. A conical cover 107 is fixedly installed on the conical cover 107, which is attached to the inner bottom of the sealed cavity block 101 and can rotate with the drive of the second servo motor 106. On the bottom surface of the conical cover 107, a plurality of first valve ports 108 are circumferentially spaced. These first valve ports 108 are through holes penetrating the bottom of the conical cover 107. At the top of the conical cover 107, a double-stirring spiral plate 109 is fixedly installed. The double-stirring spiral plate 109 is a plate-shaped structure with spiral blades, used for secondary stirring and mixing of the material entering the sealed cavity block 101. A connecting sleeve 1011 is fixedly connected at the axial center of the double-stirring spiral plate 109. This connecting sleeve 1011 is fixedly connected to the bidirectional threaded rod 1012, so that the rotation of the second servo motor 106 can simultaneously drive the bidirectional threaded rod 1012 to rotate through the conical cover 107 and the double-stirring spiral plate 109. The double-stirring spiral plate 109 is recessed in the space between the liquid replenishment cavity 103 and the second servo motor 106. On its outer side wall, a number of second valve ports 1010 are circumferentially spaced. These second valve ports 1010 are through holes penetrating the side wall of the double-stirring spiral plate 109. On the surface of the sealing cavity block 101, specifically at positions corresponding to the first valve port 108 and the second valve port 1010, there are reserved circular openings 105. These reserved circular openings 105 are through holes penetrating the housing of the sealing cavity block 101, used to align with the first valve port 108 and the second valve port 1010 at a specific angle to form a channel for material inflow and outflow.

[0081] During operation, the catalytic mechanism of the fixed-point catalytic module 10 is as follows:

[0082] First, through the aforementioned vertical and circumferential adjustment mechanisms, the fixed-point catalytic module 10 is moved to the precise position where local catalysis is required. At this time, the second magnetic control head 613 is energized to generate magnetic force, which adsorbs onto the magnetic coating on the surface of the sealed cavity block 101, ensuring that the sealed cavity block 101 remains stable during the catalytic process.

[0083] Subsequently, the second servo motor 106 is started, driving the conical cover 107 and the mixing spiral plate 109 to rotate synchronously. The rotation of the conical cover 107 causes the first valve port 108 on its bottom surface to periodically align and stagger with the reserved circular opening 105 at the bottom of the sealing chamber block 101. When the two are aligned, the resin material in the mixing cavity layer 5 can enter the internal cavity of the sealing chamber block 101 through the aligned opening. When the two are staggered, the feeding channel is closed. By controlling the rotation angle and speed of the second servo motor 106, the timing and amount of material entering the sealing chamber block 101 can be precisely controlled, and the material is prevented from seeping into the sealing chamber block 101 when the two are staggered.

[0084] Meanwhile, the rotation of the double-stirring spiral plate 109 efficiently mixes the material entering the sealed cavity block 101, and drives the bidirectional threaded rod 1012 to rotate through the connecting sleeve 1011. The rotation of the bidirectional threaded rod 1012 drives the negative pressure pusher 1013 to reciprocate inside the liquid replenishment cavity 103. When the negative pressure pusher 1013 moves upward, an upward force is generated inside the liquid replenishment cavity 103, which discharges the catalyst stored in the liquid replenishment cavity 103 into the sealed cavity block 101 through the external discharge conduit 104. When the negative pressure pusher 1013 moves downward, a negative pressure is generated, which can assist the catalyst in being drawn into the liquid replenishment cavity 103.

[0085] The thoroughly mixed catalyst-containing material is discharged into a local area of ​​the mixing cavity layer 5 when aligned with the second valve port 1010 on the outer wall of the double-stirring spiral plate 109 and the reserved circular port 105 on the side wall of the sealing cavity block 101. The fixed-point catalytic module 10 enables a closed-loop catalytic operation of drawing in local materials, injecting catalyst, and mixing and discharging at any location inside the reactor. This transforms the traditional external addition and overall mixing catalytic mode into an internal, fixed-point, micro-volume, and controllable micro-region catalytic state. Based on the real-time requirements of the gradient solidification process, the catalyst can be introduced at a specific time, location, and dosage, and released after thorough mixing with the material in that micro-region, achieving controllable intervention in the reaction process.

[0086] The usage method provided by this invention is as follows:

[0087] In use, the invention begins by starting the motor connected to the drive roller 3. The drive roller 3 rotates the main stirring rod 81. At this time, the electrically controlled magnetic coupling seat 82 is in a magnetically engaged state, fixing the auxiliary stirring rods 83 on both sides to the main stirring rod 81 as a whole. The auxiliary stirring rods 83 rotate synchronously with the main stirring rod 81, performing global stirring of the resin material in the mixing cavity layer 5. Simultaneously, the inner suction storage ring 7 is attracted to the magnetic coating on the inner wall of the annular cover plate 66 through the magnetic coating on its outer surface, causing the annular cover plate 66 to rotate together with the stirring part 8. The annular cover plate 66 is magnetically connected to the inner magnetic control sleeve plate 97 on the covered catalytic module 9 through the outer magnetic control sleeve plate 612 on the side wing plate 68, thereby driving the entire covered catalytic module 9 to rotate synchronously with the stirring part 8. If heating is required, the magnetic drive motor 11 drives the annular cover plate 66 to rotate. The annular cover plate 66 attracts the first magnetic control head 6511 through the metal notch annular groove 67, causing the auxiliary annular frame 659 to rotate. The toothed ring 6510 at the bottom of the auxiliary annular frame 659 drives the gear sleeve 653 to rotate. The gear sleeve 653 drives the first threaded rod 654 to rotate, causing the fitting frame 656 to extend along the first limiting rod 655 towards the mixing cavity layer 5. This moves the electric heating temperature control unit 657 and its segmented heating tube 658 to a working position close to the outer wall of the mixing cavity layer 5, achieving layered heating. If cooling is required, the liquid cooling temperature control unit 62 is activated. The coolant flows through the series hose 64 through each liquid cooling temperature control unit 62 and cools the vessel wall through the heat dissipation fins 63.

[0088] Then, when global catalysis is required, the internal suction storage ring 7 delivers the catalyst to the spray pipe 93 through the liquid supply hose. The spray pipe 93 sprays the catalyst evenly onto the material below as it rotates with the stirring unit 8, achieving overall catalyst distribution. When targeted catalysis is required for a specific local area, the drive roller 3 is stopped, the electro-magnetic connection fitting seat 82 is demagnetized, and the auxiliary stirring rod 83 is disconnected from the main stirring rod 81. The covered catalytic module 9 is no longer driven by the stirring unit 8. At this time, the first servo motor 610 starts, and its output drives the second threaded rod 611 to rotate, causing the outer magnetic control sleeve 612 to rise or fall along the limiting groove 69 to a preset height. The outer magnetic control sleeve 612 magnetically pulls the inner magnetic control sleeve 97, causing the entire covered catalytic module 9 to slide vertically along the main stirring rod 81 and the second limiting rod 84 to the target height. Simultaneously, the first magnetic control head 6511 cancels its adsorption with the metal notch groove 67, causing the auxiliary ring frame 659 to detach from the annular cover plate 66. Subsequently, the magnetic drive motor 11 drives the annular cover plate 66 to rotate, and the magnetic attraction between the outer magnetic control sleeve plate 612 and the inner magnetic control sleeve plate 97 drives the covered catalytic module 9 to rotate circumferentially, precisely moving the fixed-point catalytic module 10 to the target circumferential position.

[0089] Then, after the fixed-point catalytic module 10 reaches the predetermined position, the second magnetic control head 613 is energized to generate magnetic force, which attracts the magnetic coating on the surface of the sealed cavity block 101, thus stabilizing the sealed cavity block 101. The second servo motor 106 is started, and its output end drives the conical cover 107 and the double-stirring spiral plate 109 to rotate. When the conical cover 107 rotates, the first valve port 108 on its bottom surface periodically aligns with the reserved circular opening 105 at the bottom of the sealed cavity block 101, allowing some of the material in the mixing cavity layer 5 to enter the interior of the sealed cavity block 101. At the same time, the rotation of the double-stirring spiral plate 109 performs secondary stirring on the incoming material, and drives the bidirectional threaded rod 1012 to rotate through the connecting sleeve head 1011. The bidirectional threaded rod 1012 drives the negative pressure pusher 1013 to move back and forth in the replenishment cavity 103, quantitatively injecting the catalyst stored in the replenishment cavity 103 into the interior of the sealed cavity block 101 through the external discharge conduit 104, and fully mixing it with the incoming material. The mixed catalyst-containing material rotates with the double-stirring spiral plate 109. When the second valve port 1010 on its outer side wall aligns with the reserved circular port 105 on the side wall of the sealing cavity block 101, it is precisely discharged into a local area of ​​the mixing cavity layer 5 to complete the point-to-point catalysis.

[0090] Finally, after the fixed-point catalysis is completed, the second servo motor 106 stops, the second magnetic head 613 is demagnetized, and the electrically controlled magnetic connection type fitting seat 82 re-engages, so that the covered catalytic module 9 and the stirring part 8 are restored to one unit. If heating needs to be terminated, the magnetic drive motor 11 reverses the direction of the annular cover plate 66, causing the fitted frame 656 to retract away from the mixing cavity layer 5, and the electric heating temperature control unit 657 and the segmented heating tube 658 to be removed deep into the hollow frame 651 to eliminate thermal inertia. Then, the liquid cooling temperature control unit 62 can be activated for rapid cooling until the temperature inside the reactor reaches the set value. In addition, during the entire process of local catalysis, the electric heating temperature control unit 657 and the segmented heating tube 658 can also be removed deep into the hollow frame 651 in advance to ensure the stability and controllability of the internal mixing environment. The internal suction storage ring 7 can replenish the catalyst at any time through the liquid injection pipe. Each magnetic control head works in a time-sharing manner according to the control command to ensure that the heating, stirring and catalysis functions are coordinated in an orderly manner to meet the precise control requirements of the resin gradient curing process.
