[0002] Fiberglass tempering equipment is a specialized device used to enhance the mechanical properties and heat resistance of fiberglass composite materials. It softens the material through heating followed by rapid cooling or chemical ion exchange, forming a compressive stress layer on the surface, thereby improving its strength, impact resistance, and thermal stability. Typical equipment includes a preheating furnace, cooling system, transmission device, and control system, and is suitable for the production of high-performance fiberglass products in fields such as construction, transportation, and wind power.
[0003] In existing fiberglass tempering technologies, there may be a lack of centralized control equipment, leading to inconvenience in operation; temperature monitoring and control are not precise enough, making it difficult to meet the temperature requirements of different stages of fiberglass tempering; the heating and cooling of fiberglass and the transfer between different processing links may not be convenient or efficient enough; at the same time, there is a lack of real-time monitoring methods for the ion exchange process, and the heating of molten salt may be unstable, which in turn affects the efficiency and quality of fiberglass tempering. Summary of the Invention

[0005] Preferably, a first limiting frame is installed at each of the four corners of the inner cavity of the ion exchange furnace, and an air outlet is opened on the surface of both the preheating furnace and the annealing furnace; First limiting frames are precisely installed at four right-angle positions inside the ion exchange furnace. Each limiting frame is fixed to a pre-set mounting seat on the side wall of the furnace body with bolts, forming a rectangular limiting frame structure to ensure that the basket remains horizontal during ion exchange and to prevent collision with the furnace wall. At the same time, the preheating furnace and annealing furnace are structurally modified. Each gas outlet is equipped with an adjustable guide hood, which is sealed to the furnace body surface by welding. A high-temperature resistant metal filter screen is installed inside the gas outlet to control the gas circulation path inside the furnace and prevent foreign objects from entering the heating chamber. Finally, through the joint debugging and testing of temperature sensors and electrical control cabinet, it is ensured that the opening and closing status of the gas outlet forms a closed-loop control system with the heating elements and cooling devices.
[0006] Preferably, a hanger is installed on the upper surface of the suspended basket, and the winch is connected to the top of the hanger; The supporting frame structure is designed according to the geometric dimensions of the suspended platform, and a frame support is constructed by welding rectangular steel pipes. During the no-load lifting test, the winch is controlled by the electrical control cabinet to drive the frame and the suspended platform to move vertically. The deformation of the frame structure and the tightness of the connecting parts are checked simultaneously. Stress detection patches are added at the joint between the frame and the suspended platform. When the measured stress value exceeds the design load, a triangular support plate is immediately welded at the connection node to strengthen the structure.
[0007] Preferably, a second limiting frame is installed at each of the four bottom corners of the movable seat, and a third limiting frame is installed at each of the four bottom corners of the preheating furnace and the annealing furnace. The second and third limit frames are used to limit the movement of the suspended basket, allowing it to move vertically.
[0008] Preferably, each of the movable seats is equipped with a slider on its connecting side, and the preheating furnace and annealing furnace are equipped with slide rails at positions corresponding to the sliders; The slider is inserted into the slide rail, allowing the moving seat to move linearly.
[0009] Preferably, a door frame is installed at the bottom of the support frame corresponding to the openings of the preheating furnace and the annealing furnace, and a hydraulic lifting door is installed inside the door frame. The upper surface of the hydraulic lifting door is slotted at the position corresponding to the lead screw and the slide rail. The door frame is welded to the bottom of the support frame, directly opposite the openings of the preheating furnace and annealing furnace. The hydraulic lifting door is then embedded into the door frame via four sets of guide wheels. The door uses a double-layer stainless steel plate sandwiching ceramic fiber cotton, achieving vertical travel under hydraulic cylinder drive. Closed-loop control of the lifting position is achieved through a displacement sensor. Next, a slot is cut in the center of the upper surface of the hydraulic lifting door, with a retractable corrugated sealing cover installed at the edge of the slot. The slot position is calibrated using a coordinate measuring machine. Finally, during the joint debugging test, the hydraulic system is controlled by the electrical control cabinet to drive the door's lifting and lowering, simultaneously monitoring the compressive sealing force between the door and the frame. A helium leak test is performed with the door fully closed, verifying that the dynamic interference between the slot and the moving parts remains within a safe threshold.
[0010] Preferably, a feed pipe is installed at the surface inlet of the ion exchange furnace, and a discharge pipe is installed at the surface outlet of the ion exchange furnace. A circulation pump is installed on the surface of both the feed pipe and the discharge pipe. The feed and discharge pipes were customized according to the process parameters of the ion exchange furnace. A double-layered pipe structure was constructed using 316L stainless steel, with an inner pipe diameter of DN80 for molten salt transport and an outer pipe equipped with a steam-heated jacket. The feed pipe was fully penetrated and welded to the furnace inlet flange using argon arc welding. The discharge pipe was connected with a loose flange and fitted with a metal-graphite spiral wound gasket. Circulation pumps were then installed on the straight sections of both the feed and discharge pipes. The pump base was fixed to the pre-embedded base plate of the support frame using four sets of shock-absorbing bolts, and bellows compensators were installed at the pump inlet and outlet to absorb thermal expansion displacement. During pipeline pressure testing, the circulation pumps were started via the electrical control cabinet, and an ultrasonic flow meter was used to verify the medium flow rate. The pump inverter output frequency was automatically adjusted, and an automatic exhaust valve was installed at the highest point of the pipeline. Finally, during online commissioning, the molten salt temperature and ion concentration data were collected in real time using an online monitoring device. The dual-pump collaborative working mode was activated, creating a forced circulation loop between the feed and discharge pipes to ensure the uniformity of the ion exchange process.
[0011] A fiberglass tempering process, based on the aforementioned fiberglass tempering equipment, includes the following steps: S1 preheating treatment: The glass products to be processed are fed into the preheating furnace through a basket. The glass products are preheated using heating elements. During the preheating process, an intelligent temperature control system is used to dynamically adjust the preheating temperature and heating rate according to the thickness and material of the glass products, so as to ensure that the glass products are heated evenly and reduce thermal stress concentration. S2 ion exchange enhancement: After preheating, the glass products are precisely fed into the ion exchange furnace through the coordinated action of the moving seat and the winch. Inside the ion exchange furnace, the glass products are immersed in molten alkali salt to carry out the ion exchange reaction. During the ion exchange process, an online monitoring device is introduced to monitor the composition and temperature of the molten salt in real time, and the temperature of the molten salt is dynamically adjusted by the molten salt electric heater to ensure the sufficiency and uniformity of the ion exchange reaction. S3 cooling treatment: After ion exchange strengthening, the glass products are sent into an annealing furnace and cooled using a cooling device. During the cooling process, a segmented cooling process is adopted, and the cooling rate is controlled according to the thickness and material of the glass products to ensure the effective release of internal stress and avoid cracking.
[0012] Preferably, in step S1, the preheating furnace is equipped with an atmosphere control system, which can dynamically adjust the gas composition and oxygen content in the preheating furnace according to the material of the glass product. When glass products enter the preheating furnace, the electrical control cabinet first reads the product process parameters through the material identification module and automatically activates the pneumatic control system. This system consists of a gas supply unit, a gas analyzer, and a proportional control valve group. Based on the characteristics of the glass material, the system dynamically adjusts the mixing ratio of protective gases such as nitrogen and argon with oxygen through a mass flow controller. The gas mixing process is completed in the premixing chamber, and the mixed gas is evenly injected into the furnace cavity through a honeycomb gas distribution plate. At the same time, three sets of zirconia oxygen sensors installed in the furnace monitor the oxygen concentration distribution in real time, activate the PID control algorithm, and implement zoned gas supply compensation through the proportional control valve group. For special glass products containing easily oxidized elements, the system can switch to nitrogen protection mode and use a residual oxygen analyzer to continuously verify the oxygen content in the furnace. When the detected value exceeds the limit, an audible and visual alarm is automatically triggered and the heating program is paused until the atmosphere parameters return to the normal range.
[0013] Preferably, in step S2, the annealing furnace is equipped with a cooling medium, and the cooling device can automatically select and switch the cooling medium according to the thickness and material of the glass product to achieve cooling rate control and ensure effective release of internal stress in the glass product. When the ion-exchange strengthened glass products enter the annealing furnace, the electrical control cabinet first obtains the glass thickness and material data through the product information reading module, and automatically activates the intelligent medium switching system of the cooling device. This system has three built-in cooling medium channels—compressed air, fine water mist, and liquid nitrogen, each equipped with an independent solenoid valve group and flow regulating valve. The medium selection logic is based on a pre-stored process database. The liquid nitrogen cryogenic module is activated, and liquid nitrogen is mixed with the carrier gas and sprayed through a dual-fluid spray gun. At the same time, an infrared temperature measuring array monitors the surface temperature field distribution of the product in real time. When the local temperature difference exceeds the limit, the electrical control cabinet immediately adjusts the medium supply of each nozzle through pulse width modulation technology. During the medium switching process, a V-type ball valve group is used to achieve zero-leakage switching, and a pneumatic three-way valve is used to prevent medium mixing. The entire cooling process is supported by a closed-loop feedback system formed by temperature sensors.
[0014] In summary, compared with the prior art, the present invention provides a fiberglass tempering equipment and its processing technology, which has the following beneficial effects: The added electrical control cabinet facilitates centralized control of equipment operation; the preheating furnace and annealing furnace are respectively located at the feeding and discharging ends of the upper surface of the support frame, and with the temperature sensors on their surfaces, the temperature can be accurately monitored and adjusted to meet the temperature requirements of different stages of FRP tempering; heating elements are installed on the surface of the preheating furnace for heating, and cooling devices are installed on the surface of the annealing furnace for cooling, realizing the heating and cooling of FRP; the motor drives the lead screw to rotate, causing the moving seat screwed on the lead screw to move, and the winch and basket at the bottom of the moving seat can easily lift the FRP, realizing the transfer of FRP between different processing stages; an ion exchange furnace is installed on the lower surface of the support frame, and the online monitoring device on its surface can monitor the ion exchange process in real time.

[0026] The inlet and outlet ports at the bottom of the preheating furnace 2 and the annealing furnace 3 are sealed by a horizontal sealing door driven by a hydraulic system. The sealing door is opened and closed horizontally by a hydraulic cylinder. When the basket 10 is raised and lowered, the sealing door is fully opened to avoid the movement trajectory. After the basket 10 is in place, the sealing door is closed horizontally. It is pressed with the high-temperature resistant sealing strip and the furnace body interface to form an airtight structure, which not only ensures the sealing performance but also avoids interference with the movement of the basket 10.
[0027] Please see Figure 2 The four corners of the inner cavity of the ion exchange furnace 11 are each equipped with a first limiting frame 14, and the surfaces of the preheating furnace 2 and the annealing furnace 3 are each provided with an air outlet 15. First limiting frames 14 are precisely installed at four right-angle positions inside the ion exchange furnace 11. Each limiting frame is fixed to a pre-set mounting seat on the side wall of the furnace body by bolts, forming a rectangular limiting frame structure to ensure that the basket 10 remains horizontal during the ion exchange process and to prevent collision with the furnace wall. At the same time, the preheating furnace 2 and annealing furnace 3 are structurally modified. Each gas outlet 15 is equipped with an adjustable guide hood, which is sealed to the furnace body surface by welding. A high-temperature resistant metal filter screen is installed inside the gas outlet 15 to control the gas circulation path inside the furnace and prevent foreign objects from entering the heating chamber. Finally, through the joint debugging and testing of the temperature sensor 201 and the electrical control cabinet 101, it is ensured that the opening and closing state of the gas outlet 15 forms a closed-loop control system with the heating element 4 and the cooling device 5.
[0028] Please see Figure 4 A hanger 16 is installed on the upper surface of the suspended platform 10, and the winch 9 is connected to the top of the hanger 16. The structure of the supporting frame 16 is designed according to the geometric dimensions of the suspended platform 10. The frame support is made of rectangular steel pipes welded together. During the no-load lifting test, the winch 9 is controlled by the electrical control cabinet 101 to drive the frame 16 and the suspended platform 10 to move vertically. The deformation of the frame 16 structure and the tightness of the connecting parts are checked at the same time. Stress detection patches are added at the joint between the frame 16 and the suspended platform 10. When the measured stress value exceeds the design load, a triangular support plate is immediately welded at the connection node to strengthen the structure.
[0029] Please see Figure 3 Each of the four bottom corners of the movable seat 8 is equipped with a second limiting bracket 17. Please refer to [link / reference]. Figure 4 The preheating furnace 2 and the annealing furnace 3 are each equipped with a third limiting frame 18 at the four corners of their bottoms; The second limiting frame 17 and the third limiting frame 18 are used to limit the basket 10, so that the basket 10 can move vertically.
[0030] Please see Figure 3 Sliders 22 are installed on the connecting side of the movable seat 8, and slide rails 23 are installed in the preheating furnace 2 and the annealing furnace 3 at the corresponding positions of the sliders 22. The slider 22 is inserted into the slide rail 23, enabling the movable seat 8 to move linearly.
[0031] Please see Figure 2 Door frames 19 are installed at the bottom of support frame 1, corresponding to the openings of preheating furnace 2 and annealing furnace 3. Hydraulic lifting doors 20 are installed inside each door frame 19. Please refer to [link / reference]. Figure 6 The upper surface of the hydraulic lifting door 20 is provided with slots 21 at the corresponding positions of the lead screw 7 and the slide rail 23; A door frame 19 is welded to the bottom of the support frame 1, directly opposite the openings of the preheating furnace 2 and the annealing furnace 3. Then, a hydraulic lifting door 20 is embedded into the door frame 19 via four sets of guide wheels. The door uses a double-layer stainless steel plate sandwiching ceramic fiber cotton, achieving vertical travel under hydraulic cylinder drive, and closed-loop control of the lifting position is achieved through a displacement sensor. Next, a slot 21 is opened in the center of the upper surface of the hydraulic lifting door 20, with a retractable corrugated sealing cover installed at the edge of the slot. The position of the slot 21 is calibrated using a coordinate measuring machine. Finally, during the joint debugging test, the hydraulic system is controlled by the electrical control cabinet 101 to drive the door to lift and lower, simultaneously monitoring the compression sealing force between the door and the frame. A helium leak test is performed with the door fully closed, verifying that the dynamic interference between the slot 21 and the moving parts remains within a safe threshold.
[0032] Please see Figure 5 A feed pipe 24 is installed at the feed inlet on the surface of the ion exchange furnace 11, and a discharge pipe 25 is installed at the discharge outlet on the surface of the ion exchange furnace 11. A circulating pump 26 is installed on the surface of both the feed pipe 24 and the discharge pipe 25. The feed pipe 24 and discharge pipe 25 are customized according to the process parameters of the ion exchange furnace 11. A double-layered pipe structure is made of 316L stainless steel, with an inner pipe diameter of DN80 for molten salt transport and an outer pipe equipped with a steam tracing jacket. The feed pipe 24 is fully penetrated and welded to the furnace inlet flange using argon arc welding. The discharge pipe 25 uses a loose flange connection and is fitted with a metal-graphite spiral wound gasket. Subsequently, circulating pumps 26 are installed on the straight sections of the feed pipe 24 and discharge pipe 25, respectively. The pump base is fixed to the pre-embedded support frame 1 using four sets of shock-absorbing bolts. On the substrate, bellows compensators are configured at the pump inlet and outlet to absorb thermal expansion displacement; then, during the pipeline pressure test, the circulating pump 26 is started through the electrical control cabinet 101, the medium flow rate is verified using an ultrasonic flow meter, the output frequency of the pump body frequency converter is automatically adjusted, and an automatic exhaust valve is installed at the highest point of the pipeline; finally, during the online commissioning, the molten salt temperature and ion concentration data are collected in real time through the online monitoring device 12, and the dual pump collaborative working mode is started, so that the feed pipe 24 and the discharge pipe 25 form a forced circulation loop to ensure the uniformity of the ion exchange process.
[0033] Please see Figure 7 A fiberglass tempering process, based on the aforementioned fiberglass tempering equipment, includes the following steps: S1 preheating treatment: The glass products to be processed are sent into the preheating furnace 2 through the basket 10. The glass products are preheated using the heating element 4. During the preheating process, an intelligent temperature control system is used to dynamically adjust the preheating temperature and heating rate according to the thickness and material of the glass products to ensure that the glass products are heated evenly and reduce thermal stress concentration. S2 ion exchange enhancement: After preheating, the glass products are precisely fed into the ion exchange furnace 11 through the coordinated action of the moving seat 8 and the winch 9. Inside the ion exchange furnace 11, the glass products are immersed in molten alkali salt to carry out the ion exchange reaction. During the ion exchange process, an online monitoring device 12 is introduced to monitor the composition and temperature of the molten salt in real time, and the temperature of the molten salt is dynamically adjusted by the molten salt electric heater 13 to ensure the sufficiency and uniformity of the ion exchange reaction. S3 cooling treatment: After ion exchange strengthening, the glass products are sent into annealing furnace 3 and cooled by cooling device 5. During the cooling process, a segmented cooling process is adopted. The cooling rate is controlled according to the thickness and material of the glass products to ensure the effective release of internal stress and avoid cracking.
[0034] In step S1, an atmosphere control system is installed in the preheating furnace 2. The atmosphere control system can dynamically adjust the gas composition and oxygen content in the preheating furnace according to the material of the glass products. When glass products enter preheating furnace 2, electrical control cabinet 101 first reads the product process parameters through the material identification module and automatically activates the pneumatic control system. This system consists of a gas supply unit, a gas analyzer, and a proportional control valve group. According to the characteristics of the glass material, the system dynamically adjusts the mixing ratio of protective gases such as nitrogen and argon with oxygen through a mass flow controller. The gas mixing process is completed in the premixing chamber, and the mixed gas is evenly injected into the furnace cavity through a honeycomb gas distribution plate. At the same time, three sets of zirconia oxygen sensors installed in the furnace monitor the oxygen concentration distribution in real time, start the PID adjustment algorithm, and implement zoned gas supply compensation through the proportional control valve group. For special glass products containing easily oxidized elements, the system can switch to nitrogen protection mode and use a residual oxygen analyzer to continuously verify the oxygen content in the furnace. When the detected value exceeds the limit, an audible and visual alarm is automatically triggered and the heating program is paused until the atmosphere parameters return to the normal range.
[0035] In step S2, the annealing furnace 3 is equipped with a cooling medium. The cooling device 5 can automatically select and switch the cooling medium according to the thickness and material of the glass product to achieve cooling rate control and ensure the effective release of internal stress in the glass product. When the ion-exchange strengthened glass products enter the annealing furnace 3, the electrical control cabinet 101 first obtains the glass thickness and material data through the product information reading module, and automatically activates the intelligent medium switching system of the cooling device 5. The system has three built-in cooling medium channels—compressed air, fine water mist, and liquid nitrogen, each equipped with an independent solenoid valve group and flow regulating valve. The medium selection logic is based on the pre-stored process database. The liquid nitrogen deep cryogenic module is started, and liquid nitrogen is mixed with the carrier gas and sprayed through a dual-fluid spray gun. At the same time, an infrared temperature measuring array is equipped to monitor the surface temperature field distribution of the product in real time. When the local temperature difference exceeds the limit, the electrical control cabinet 101 immediately adjusts the medium supply of each nozzle through pulse width modulation technology. During the medium switching process, a V-type ball valve group is used to achieve zero-leakage switching, and a pneumatic three-way valve is used to prevent medium mixing. The entire cooling process is supported by a closed-loop feedback system formed by the temperature sensor 201.
[0036] In the fiberglass tempering process, the fiberglass to be processed is first placed in the suspended basket 10. The winch 9, connected to the hanger 16 on the upper surface of the suspended basket 10, provides power for lifting the basket 10. The motor 6 starts, and its rotor drives the coaxially mounted lead screw 7 to rotate. Since the moving seat 8 is screwed onto the lead screw 7, the moving seat 8 begins to move under the action of the rotation of the lead screw 7. The slider 22 installed on the connecting side of the moving seat 8 cooperates with the slide rail 23 installed on the preheating furnace 2 and the annealing furnace 3 to provide guidance and support for the movement of the moving seat 8, ensuring the smoothness of the movement. At the same time, the second limit frame 17 installed at the four corners of the bottom of the moving seat 8 can prevent the moving seat 8 from deviating or other abnormal situations during the movement.
[0037] The movable seat 8 moves the suspended basket 10 to the position of the preheating furnace 2. The heating element 4 on the surface of the preheating furnace 2 starts working to heat the inside of the furnace, providing a preheating temperature environment for the fiberglass. The temperature sensor 201 on the surface of the preheating furnace 2 monitors the temperature inside the furnace in real time to ensure that the preheating temperature meets the process requirements. At the same time, the vent 15 on the surface of the preheating furnace 2 can discharge the waste gas generated inside the furnace. The hydraulic lifting door 20 inside the door frame 19 installed at the bottom of the support frame 1, corresponding to the opening of the preheating furnace 2, is raised to facilitate the entry of the suspended basket 10 into the preheating furnace 2. The slot 21 on the upper surface of the hydraulic lifting door 20, corresponding to the screw 7 and the slide rail 23, can avoid interference with the screw 7 and the slide rail 23.
[0038] After preheating, the movable seat 8 continues to move the basket 10 to above the ion exchange furnace 11 below the support frame 1. The feed pipe 24 installed at the feed inlet on the surface of the ion exchange furnace 11 and the circulating pump 26 on the surface transport the fiberglass into the ion exchange furnace 11. The first limiting frame 14 installed at the four corners of the inner cavity of the ion exchange furnace 11 limits the fiberglass and prevents it from shaking inside the furnace. The molten salt electric heater 13 on the surface of the ion exchange furnace 11 heats the molten salt in the furnace, providing suitable temperature conditions for the ion exchange of the fiberglass. The online monitoring device 12 on the surface monitors the relevant parameters of the ion exchange process in real time to ensure the quality of the ion exchange.
[0039] After ion exchange, the fiberglass is output through the discharge pipe 25 installed at the discharge port on the surface of the ion exchange furnace 11 and the surface circulation pump 26. The moving seat 8 moves the basket 10 to the position of the annealing furnace 3. The cooling device 5 on the surface of the annealing furnace 3 starts to work to cool the fiberglass and achieve the purpose of annealing. The temperature sensor 201 on the surface of the annealing furnace 3 monitors the temperature inside the furnace to ensure that the annealing temperature is appropriate, and the exhaust port 15 on the surface discharges waste gas. The third limit frame 18 installed at the four corners of the bottom of the annealing furnace 3 plays a role in stabilizing the annealing furnace 3. Similarly, the hydraulic lifting door 20 rises when the fiberglass enters the annealing furnace 3, and the slot 21 avoids interference, completing the entire fiberglass tempering process.
