Description

Technical Field

[0001] This invention relates to the field of matrix resin fluid heating technology, and more particularly to a mixed matrix resin heating device and construction method. Background Technology

[0002] When producing FRP (fiberglass reinforced plastic) pipes and tanks at low temperatures, the viscosity of the matrix resin increases significantly, and its fluidity decreases. When extruded or used to impregnate fibers, greater pressure is required to propel it, easily leading to uneven flow channels on the pipe wall or between fibers, causing localized stress concentration. Furthermore, under low-temperature, high-viscosity conditions, fillers are difficult to disperse evenly with the matrix resin, and there is even a risk of separation. Therefore, it is necessary to moderately heat the matrix resin using a heating device to reduce its viscosity, allowing the resin to flow smoothly, reducing resistance during extrusion and effectively lowering internal stress. However, the heating temperature should not be too high. If the temperature exceeds a reasonable range, the matrix resin will prematurely enter a significant cross-linking reaction stage, posing a risk of premature curing, shortening the shelf life, and potentially causing premature gelation before construction is complete, thus affecting the layup and impregnation effects.

[0003] Currently, water bath heating devices are commonly used in production sites to heat the matrix resin. However, water bath heating devices have a complex structure, occupy a large area, and are inconvenient to move. At the same time, water bath heating coils are difficult to keep warm, most of the heat is easily lost, the thermal energy utilization efficiency is low, and the maintenance and operation are very cumbersome.

[0004] Therefore, there is an urgent need for a heating device and construction method for a mixed matrix resin to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a heating device and construction method for mixing matrix resins. The device has a simple structure, occupies little space, is easy to disassemble and move, and can mix and heat at least one matrix resin and realize real-time monitoring of heating temperature. At the same time, the device has good heat preservation performance, effectively improves thermal energy utilization efficiency, and is easy to maintain and clean.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0013] As an optional solution for the heating device of the mixed matrix resin, the heating mechanism also includes a fixing bracket, which is placed outside the glue storage cylinder and located on the side of the glue injection joint, for fixing the position of the glue injection end cap assembly to prevent it from rotating.

[0014] As an optional solution for the heating device for the mixed matrix resin, the glue injection joint includes a first glue injection joint, a second glue injection joint, a glue inlet joint, and a tee joint. The first glue injection joint, the second glue injection joint, and the glue inlet joint are respectively connected through the tee joint. The other end of the glue inlet joint is connected to the glue injection end cap body. The other ends of the first glue injection joint and the other ends of the second glue injection joint are respectively connected to the input ends of different types of matrix resin.

[0015] As an optional solution for the heating device of the mixed matrix resin, the heating element includes a heating rod and a connector. The heating rod is arranged along the axial direction of the glue storage cylinder, and its two ends pass through the glue injection end cap assembly and the glue dispensing end cap assembly. The connector is fixedly connected to both ends of the heating rod and connected to the glue injection end cap assembly and the glue dispensing end cap assembly, so as to securely install the heating rod in the glue storage cylinder.

[0016] As an optional solution for heating the mixed matrix resin, the heating rod is positioned at the central axis of the resin storage cylinder.

[0017] As an alternative to the heating device for the mixed matrix resin, the static mixer is in the form of an S-shaped coil spiral.

[0019] A method for heating and applying a mixed matrix resin, using a mixed matrix resin heating device as described in any of the above claims, includes the following steps:

[0020] S1: Sequentially seal and connect the glue injection end cap assembly, the glue storage cylinder, and the glue dispensing end cap assembly to form the glue storage cavity; place the heating element and the static mixer in the glue storage cavity, install the temperature measuring element on the surface of the heating element, and electrically connect the heating element, the temperature measuring element, and the intelligent temperature control component to complete the initial assembly of the device;

[0022] S3: The temperature control mechanism is activated. The intelligent temperature control component monitors the surface temperature of the heating element in real time according to the temperature measuring element. When the temperature is lower than the preset temperature, the heating element continues to heat. When the temperature reaches the preset temperature, the intelligent temperature control component controls the heating element to stop heating and heats the matrix resin in the resin storage cavity to the preset temperature.

[0023] S4: After heating is completed, the matrix resin in the glue storage cavity is discharged through the glue outlet end cap assembly, thus completing the heating construction process.

[0024] The beneficial effects of this invention are:

[0025] This invention provides a heating device and construction method for a mixed matrix resin, including a heating mechanism and a temperature control mechanism. The heating mechanism includes a glue injection end cap assembly, a glue dispensing end cap assembly, a glue storage cylinder, a heating element, and a static mixer. The matrix resin is injected into the glue storage cylinder through the glue injection end cap assembly and discharged through the glue dispensing end cap assembly. The glue injection end cap assembly, the glue dispensing end cap assembly, and the glue storage cylinder are detachably sealed, ensuring airtightness during operation and facilitating subsequent maintenance and cleaning, resulting in a simple structure. The temperature control mechanism includes a temperature sensor mounted on the heating element. Its input end is electrically connected to the heating element, enabling real-time monitoring of the heating element's surface temperature. The output end of the temperature sensor is electrically connected to an intelligent temperature control component, which is also electrically connected to the heating element, thus achieving closed-loop control of the heating state. When the temperature sensor detects that the surface temperature of the heating element reaches a preset value, it transmits a signal to the intelligent temperature control component, which then controls the heating element to stop heating. When the monitored temperature falls below the preset value, the intelligent temperature control component restarts the heating element, allowing it to continue operating. This allows the heating element's operating temperature to be maintained within a preset range, ensuring the matrix resin remains in its optimal flow state of high fluidity and low viscosity. This reduces resistance during extrusion, effectively lowers internal stress, and prevents premature curing of the matrix resin due to excessively high temperatures. Because the device can provide intermittent continuous heating and the storage chamber has thermal insulation properties, its structure can be designed to be miniaturized, occupying little space and facilitating disassembly and relocation. This helps improve thermal efficiency and reduce energy consumption. The static mixer enables thorough and uniform mixing of multi-component matrix resins. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0035] Please refer to Figure 1As shown, this embodiment provides a heating device for mixing matrix resin, including a heating mechanism 1 and a temperature control mechanism 2. The heating mechanism 1 includes a glue injection end cap assembly 11, a glue dispensing end cap assembly 12, a glue storage cylinder 13, a heating element 14, and a static mixer 15. The glue injection end cap assembly 11, the glue storage cylinder 13, and the glue dispensing end cap assembly 12 are sequentially and detachably sealed together to form a glue storage cavity with heat preservation function. The heating element 14 is detachably installed inside the glue storage cylinder 13 for heating the injected matrix resin. The static mixer 15 is detachably installed inside the glue storage cylinder 13 for mixing the injected matrix resin. The temperature control mechanism 2 includes a temperature measuring element 21 and an intelligent temperature control component 22. The temperature measuring element 21 is installed outside the heating element 14, and the heating element 14, the temperature measuring element 21, and the intelligent temperature control component 22 are electrically connected.

[0036] The matrix resin is injected into the glue storage cylinder 13 through the glue injection end cap assembly 11 and discharged through the glue dispensing end cap assembly 12. The glue injection end cap assembly 11, the glue dispensing end cap assembly 12, and the glue storage cylinder 13 are detachably sealed, ensuring airtightness during operation and facilitating subsequent maintenance and cleaning, resulting in a simple structure. The temperature measuring element 21 in the temperature control mechanism 2 is mounted on the heating element 14. Its input end is electrically connected to the heating element 14, enabling real-time monitoring of the surface temperature of the heating element 14. The output end of the temperature measuring element 21 is electrically connected to the intelligent temperature control component 22, which is also electrically connected to the heating element 14, thus achieving closed-loop control of the heating state. When the temperature measuring element 21 detects that the surface temperature of the heating element 14 reaches a preset value, it transmits a signal to the intelligent temperature control component 22, which then controls the heating element 14 to stop heating. When the monitored temperature is lower than the preset value, the intelligent temperature control component 22 restarts the heating element 14, allowing it to continue operating. This ensures that the operating temperature of the heating element 14 is maintained within a preset range, guaranteeing that the matrix resin is always in an optimal flow state with high fluidity and low viscosity. This reduces resistance during extrusion, effectively lowers internal stress, and prevents premature curing of the matrix resin due to excessively high temperatures. Because the device can provide intermittent continuous heating and the storage chamber has thermal insulation properties, its structure can be designed to be miniaturized, occupying little space and facilitating disassembly and relocation. This helps improve thermal energy utilization and reduce energy consumption. The static mixer 15 enables thorough and uniform mixing of multi-component matrix resins.

[0037] Optionally, the glue storage cylinder 13 adopts a double-layer structure, with the inner layer being metal (such as stainless steel) to ensure the main body strength and thermal conductivity, and the outer layer being covered with heat insulation material (such as ceramic fiber, polyurethane foam, aluminum silicate cotton). This allows the container to withstand pressure while reducing heat loss, thus having a heat preservation effect and improving the thermal energy utilization rate.

[0038] Specifically, the heating mechanism 1 also includes multiple fastening components 16. Each fastening component 16 includes a connecting screw 161 and a connecting nut 162. Multiple mounting holes are axially drilled through the inner wall of the glue storage cylinder 13, and these mounting holes are spaced apart circumferentially along the cylinder wall. The connecting screw 161 passes sequentially through the glue injection end cap assembly 11, the mounting holes, and the glue dispensing end cap assembly 12, with its two ends threadedly connected by the connecting nuts 162. This allows the glue injection end cap assembly 11, the glue storage cylinder 13, and the glue dispensing end cap assembly 12 to be mutually compacted and fixedly sealed. The combination of the connecting screw 161 and the connecting nut 162 not only allows the glue injection end cap assembly 11 and the glue dispensing end cap assembly 12 to be mutually compacted and connected to the glue storage cylinder 13 through rotation, but also withstands the forces of thermal expansion or operational vibration during heating, improving overall rigidity. Furthermore, the multiple fastening components 16 are distributed circumferentially along the cylinder wall, forming a uniform force distribution, ensuring even stress on the end caps and preventing localized stress concentration. The injection connector 112 is located at the highest point of the end cap, allowing the base resin to be injected from above and smoothly enter the resin reservoir 13 under its own weight. The dispensing connector 122 works similarly, facilitating even resin discharge and preventing residue or air bubbles. Optionally, the number of fastening components 16 can be four, six, or seven, etc., and is not limited here.

[0039] More specifically, the glue-injecting end cap assembly 11 includes a glue-injecting end cap body 111, a glue-injecting connector 112, and a first sealing ring 113. The glue-injecting connector 112 is located at the highest point of the glue-injecting end cap body 111 and is detachably connected to the glue-injecting end cap body 111. The first sealing ring 113 is sandwiched between the glue-injecting end cap body 111 and the glue storage cylinder 13. The glue-dispensing end cap assembly 12 includes a glue-dispensing end cap body 121, a glue-dispensing connector 122, and a second sealing ring 123. The glue-dispensing connector 122 is located at the highest point of the glue-dispensing end cap body 121 and is detachably connected to the glue-injecting end cap body 111. The system features a detachable connection, with the second sealing ring 123 sandwiched between the dispensing end cap body 121 and the glue storage cylinder 13. For high-temperature or viscous base resins, the first sealing ring 113 and the second sealing ring 123 ensure the airtightness of the glue storage cavity during operation, effectively preventing leakage of base resin from the interface. The glue injection connector 112 is located at the highest point of the glue injection end cap body 111, allowing the base resin to be injected from above and smoothly enter the glue storage cylinder 13 using gravity or pressure. Similarly, the dispensing connector 122 facilitates uniform resin discharge and avoids residue or air bubbles.

[0040] Optionally, the glue injection connector 112 includes a first glue injection connector 1121, a second glue injection connector 1122, a glue inlet connector 1123, and a three-way connector 1124. The first glue injection connector 1121, the second glue injection connector 1122, and the glue inlet connector 1123 are connected to the three-way connector 1124. The other end of the glue inlet connector 1123 is connected to the glue injection end cap body 111. The other ends of the first glue injection connector 1121 and the second glue injection connector 1122 are respectively connected to the input ends of different types of matrix resins. In this way, multiple matrix resins can be input through the first glue injection connector 1121 and the second glue injection connector 1122 respectively, and converge at the three-way connector 1124, so as to enter the glue storage cylinder 13 through the glue inlet connector 1123, avoiding multiple disassembly or replacement of connectors and improving the ease of operation. Meanwhile, different types of matrix resins can be initially combined before entering the storage tank 13. Combined with the static mixer 15 installed inside the storage tank 13, the mixing effect of the resin can be further guaranteed and the mixing uniformity can be improved.

[0041] Optionally, both the first sealing ring 113 and the second sealing ring 123 are made of polytetrafluoroethylene (PTFE). The first sealing ring 113 and the second sealing ring 123 made of this material have excellent corrosion resistance and high hardness, as well as high compressibility and strong three-dimensional forming ability, allowing them to be embedded into micro-cracks or damaged areas to achieve crack repair and leak sealing. Simultaneously, they can effectively compensate for gaps caused by rigid deformation, manufacturing defects, machining errors, and installation deviations, balancing the problem of uneven preload distribution. Therefore, they can effectively solve the potential leakage risks of the device under complex operating conditions and reduce the adverse effects of pressure fluctuations, temperature changes, and mechanical vibrations on sealing performance.

[0042] Since the glue storage cylinder 13, the glue injection end cap body 111, and the glue dispensing end cap body 121 are all circular, they are prone to rotation during operation, making it impossible to keep the glue injection connector 112 and the glue dispensing connector 122 in constant position. To solve the above problem, in some embodiments, the heating mechanism 1 also includes a fixing bracket 17. The fixing bracket 17 is placed outside the glue storage cylinder 13 and located on the side of the glue injection connector 112. It is used to fix the position of the glue injection end cap assembly 11 to prevent it from rotating, so that the fluid in the glue storage cavity flows in the expected direction, which is beneficial for uniform heating and thorough mixing. The fixing bracket 17 can adopt an L-shaped plate structure. One side of the L-shaped plate is fixedly connected to the glue injection end cap body 111, and the other side abuts against the outer wall of the glue storage cylinder 13. The L-shaped plate has a clearance hole to avoid interference with components such as the connecting screw 161. The connecting screw 161 can pass through the clearance hole, and the connecting nut 162 abuts against the L-shaped plate, thereby achieving further fixation of the fixing bracket 17.

[0043] In some optional embodiments, the heating element 14 includes a heating rod 141 and a connector 142. The heating rod 141 is arranged axially along the glue storage cylinder 13, with its two ends passing through the glue injection end cap assembly 11 and the glue dispensing end cap assembly 12. The connector 142 is fixedly connected to both ends of the heating rod 141 and connected to the glue injection end cap assembly 11 and the glue dispensing end cap assembly 12, so as to securely install the heating rod 141 inside the glue storage cylinder 13. By fixing both ends of the heating rod 141 to the glue injection end cap assembly 11 and the glue dispensing end cap assembly 12 respectively through the connector 142, the heating rod 141 remains stable inside the glue storage cylinder 13 and will not be displaced due to vibration or fluid impact, thus ensuring heating reliability. The heating rod 141 is arranged axially along the glue storage cylinder 13, which can achieve uniform heating of the fluid inside the glue storage cylinder 13, avoiding local overheating or excessive temperature gradient, thereby improving heating efficiency and resin flowability.

[0044] Furthermore, the heating rod 141 is positioned at the central axis of the resin storage cylinder 13, which enables heat to be evenly conducted to the surrounding area, avoiding overheating near the cylinder wall and insufficient heating in the central area, thereby ensuring a more uniform overall temperature distribution of the matrix resin.

[0045] Optionally, sealing rings can be provided at the contact points between the heating rod 141 and the glue injection end cap assembly 11 and the glue dispensing end cap assembly 12 to give the device better sealing performance.

[0046] Optionally, the heating rod 141 can pass through the glue injection end cap body 111 and the glue dispensing end cap body 121 at both ends, and be threadedly connected to the nut. The nut abuts against the glue injection end cap body 111 and the glue dispensing end cap body 121 to form a reliable axial clamping force, so that it is firmly fixed and avoids loosening.

[0047] Optionally, the static mixer 15 is in the shape of an S-shaped coil spiral, which allows for multiple splitting and merging of the fluid during its passage, thereby significantly improving the mixing uniformity of the matrix resin. Simultaneously, the S-shaped coil spiral structure provides a large contact area with the heating rod 141, which not only improves heating efficiency but also ensures a more uniform temperature distribution during heating, guaranteeing a higher linear fit for temperature control, thus effectively improving overall heating and mixing performance. Furthermore, the static mixer 15 is made of rigid polyvinyl chloride material, effectively preventing corrosion and extending its service life.

[0048] Specifically, the intelligent temperature control component 22 includes an AC contactor 221, an alarm 222, a display screen 223, and an electrical control box 224. The electrical control box 224 is located outside the heating mechanism 1, and the AC contactor 221, alarm 222, and display screen 223 are all housed within the electrical control box 224. The AC contactor 221, alarm 222, display screen 223, heating element 14, and temperature measuring element 21 are electrically connected. The temperature measuring element 21 monitors the temperature of the heating rod 141 inside the glue storage cylinder 13 in real time and transmits the temperature signal to the intelligent temperature control component 22. The display screen 223 inside the electrical control box 224 simultaneously displays the current temperature, allowing the operator to understand real-time temperature changes. When the temperature is lower than a preset value, the AC contactor 221 closes, energizing the heating element 14 for heating. When the temperature reaches the set upper limit, the AC contactor 221 opens, stopping the heating element 14 from heating, thus achieving constant temperature control. At the same time, when the temperature reaches the preset value, the alarm 222 will issue a prompt, reminding the operator that the temperature has reached the appropriate range and output operation can be performed.

[0049] Optionally, the alarm device can be a 222-type illuminated buzzer alarm, which can provide timely reminders and enable operators to quickly identify the problem.

[0050] Optionally, the temperature measuring element 21 may be a temperature sensor, which is not specifically limited here.

[0051] Please refer to Figure 2 As shown, this embodiment also provides a method for heating and applying a mixed matrix resin, using the mixed matrix resin heating device from any of the above embodiments, including the following steps:

[0052] S1: Separately seal and connect the glue injection end cap assembly 11, the glue storage cylinder 13, and the glue dispensing end cap assembly 12 to form a glue storage cavity; place the heating element 14 and the static mixer 15 into the glue storage cavity, install the temperature measuring element 21 on the surface of the heating element 14, and electrically connect the heating element 14, the temperature measuring element 21, and the intelligent temperature control component 22 to complete the initial assembly of the device;

[0053] S2: The matrix resin is injected into the glue storage cylinder 13 through the glue injection end cap assembly 11, flows through the glue storage cylinder 13 to the static mixer 15, and is fully mixed under the action of the static mixer 15.

[0054] S3: Start the temperature control mechanism 2. The intelligent temperature control component 22 monitors the surface temperature of the heating element 14 in real time according to the temperature measuring element 21. When the temperature is lower than the preset temperature, the heating element 14 continues to heat. When the temperature reaches the preset temperature, the intelligent temperature control component 22 controls the heating element 14 to stop heating and heats the matrix resin in the storage cavity to the preset temperature.

[0055] S4: After heating is completed, the matrix resin in the glue storage cavity is discharged through the glue outlet end cap assembly 12, thus completing the heating construction process.

[0056] The surface temperature of the heating element 14 is monitored in real time by the temperature measuring element 21. The intelligent temperature control component 22 automatically controls the heating switch based on the temperature feedback to achieve constant temperature heating. This ensures that the matrix resin is always in the optimal state of high fluidity and low viscosity, reducing resistance during extrusion and effectively reducing internal stress. The intelligent temperature control and the temperature measuring element 21 work together to maintain constant temperature control, avoiding overheating or underheating of the resin, reducing equipment damage and construction risks. At the same time, the matrix resin is thoroughly mixed by the static mixer 15, ensuring uniform distribution of different types of matrix resin, improving mixing effect and subsequent construction quality. All components are detachable and connectable, facilitating cleaning, maintenance, and replacement of parts, extending the service life of the device. Because the device can provide intermittent continuous heating and the resin storage chamber has heat preservation properties, its structure can be designed to be miniaturized, occupying little space and facilitating disassembly and relocation, which helps to improve thermal energy utilization and reduce energy consumption. The static mixer 15 can achieve thorough and uniform mixing of multi-component matrix resins.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
