Description

Technical Field

[0001] This invention relates to the field of industrial automation control technology, specifically a control system for a glass autoclave. Background Technology

[0002] A glass autoclave is a key piece of equipment used in the manufacture of laminated glass. It is widely used in the glass deep processing industry, especially in the manufacturing process of laminated glass. Its core function is to efficiently clamp the PVB film and glass through heating and pressurization processes to enhance the glass's impact resistance, sound insulation, and safety.

[0003] Many existing autoclaves rely on manual operation, including opening and closing the autoclave door, adjusting temperature and pressure, which not only increases labor intensity but may also lead to operational errors and low production efficiency. The lack of a real-time data monitoring and recording system makes it difficult to trace and optimize key parameters in the production process. Summary of the Invention

[0004] The purpose of this invention is to provide a control system for a glass autoclave to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a control system for a glass autoclave, the system comprising: a data acquisition module, a PLC core control module, a safety interlock module, a network communication module, a touch screen operation module, and a data recording and storage module; The data acquisition module collects real-time data through sensors, including photoelectric sensors, vessel door status sensors, air temperature thermocouples, high-temperature resistant special pressure sensors, flow meters, and cooling water temperature sensors. The real-time data includes glass position, vessel door opening / closing status, vessel internal temperature, vessel internal pressure, cooling water flow rate, and cooling water inlet / outlet temperature. The real-time data is then transmitted to the PLC core control module and the data recording and storage module. The PLC core control module is used to receive real-time data transmitted by the data acquisition module, perform real-time data processing, and complete automatic control based on the real-time data processing results. The automatic control includes automatic opening and closing of the vessel door, automatic heating, automatic hot air circulation, automatic pressurization, automatic depressurization, and automatic cooling. The automatic control and real-time data are transmitted to the network communication module, the safety interlock module, and the data recording and storage module. The PLC core control module includes a quick-opening door module, an electric heating module, a pressure module, a heat exchange module, and a hot air circulation module. The quick-opening door module includes a toothed flange, a drive device, and a silicone sealing ring for opening and closing the vessel door. The electric heating module includes a solid-state relay and a nickel-chromium alloy finned heating element for heating the internal temperature of the vessel. The pressure module includes two pilot-operated solenoid valves controlling the inlet and outlet airflow, two manually controlled outlet ball valves, and a silencer for regulating and controlling the internal pressure of the vessel. The heat exchange module includes cooling water, a surface-cooled finned heat exchanger, and a drainage structure for reducing the internal temperature of the vessel. The hot air circulation module includes a centrifugal impeller fan and a U-shaped air duct for uniformly distributing the internal temperature of the vessel. The safety interlock module receives automatic control and real-time data transmitted by the PLC core control module, provides safety protection reminders and fault alarms to the PLC core control module, and transmits the fault alarm information to the network communication module and the data recording and storage module. The network communication module receives real-time data transmitted by the PLC core control module and fault alarm information transmitted by the safety interlock module, and transmits them to the touch screen operation module. Through the network communication module, remote monitoring and operation can be realized, improving the flexibility of operation. The touchscreen operation module is used to provide an operation interface to the user, which displays real-time data and fault alarms; the user can perform manual control and process query through the operation interface. The data recording and storage module is used to store and record automatic control and real-time data and x sets of process parameters transmitted by the PLC core control module; where x represents the number of sets of process parameters stored in the data recording and storage module; the process parameters are stored in the form of a table, which contains all relevant parameters in each set of process parameters, and each set of process parameters forms a unique process number; the relevant parameters include heating temperature, holding temperature, pressure, heating time, holding time, cooling time, steam flow rate, upper temperature limit, and upper pressure limit.

[0006] According to the above scheme, the automatic opening and closing reactor door includes: When the quick-opening door module detects a workflow or production requirement that glass needs to enter the glass autoclave, the hydraulic system in the drive unit is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the closed position to the open position. At the same time, the toothed flange separates, and the autoclave door is fully opened. When the quick-opening door module detects that the glass has completely entered or exited the glass autoclave, the hydraulic system in the drive unit is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the open position to the closed position. At the same time, the toothed flange engages, the autoclave door closes, and the silicone sealing ring is pressed tightly.

[0007] According to the above scheme, the automatic heating includes: According to the process parameters stored in the data recording and storage module, the required heating temperature is set; when the internal temperature of the vessel is lower than the set heating temperature, the electric heating module sends a heating control signal to activate the solid-state relay. The solid-state relay controls the current to flow through the nickel-chromium alloy finned heating element, causing the nickel-chromium alloy finned heating element to heat up and complete the heating process. The electrothermal conversion rate of nickel-chromium alloy finned heating elements is over 95%, and the service life is 15,000 hours.

[0008] According to the above scheme, the automatic pressurization and the automatic depressurization include: Based on the process parameters saved by the data recording and storage module, the required heating temperature is set; the pressure module determines whether the internal temperature of the autoclave has reached the set temperature. When the set temperature is reached, the pressure module controls the pilot solenoid valve to open the pneumatic ball valve, allowing compressed air or steam to enter the glass autoclave and start automatic pressurization, so that the PVB film and glass are evenly bonded. Once the PVB film is fully bonded to the glass and forms a robust laminated glass, the pressure module controls the pilot solenoid valve to open the pneumatic ball valve, initiating automatic pressure relief to reduce the internal pressure of the vessel. Simultaneously, the silencer reduces the noise generated during exhaust.

[0009] According to the above scheme, manual pressure relief can be performed through the two manually controlled exhaust ball valves in the pressure module; when pressure relief is required, rotate or adjust the two manually controlled exhaust ball valves to open the exhaust passage; when the required pressure level is reached, close the two manually controlled exhaust ball valves to stop the exhaust.

[0010] According to the above scheme, the automatic cooling includes: Based on the process parameters saved by the data recording and storage module, the required heat preservation time is set; when the heat preservation time ends, the heat exchange module controls the cooling water to flow into the surface-cooled finned heat exchanger; when the cooling water flows in the surface-cooled finned heat exchanger, it absorbs heat and carries away the heat inside the vessel, thus automatically reducing the internal temperature of the vessel; when the automatic cooling ends, the cooling water is discharged from the drainage structure.

[0011] According to the above scheme, the automatic hot air circulation includes: When heating begins in the glass autoclave, the hot air circulation module sends a hot air circulation control signal, and the centrifugal impeller fan generates forced convection through the centrifugal impeller to send hot air into the U-shaped air duct; the hot air is evenly pushed to the bottom and sides of the autoclave through the U-shaped air duct, so that the hot air inside the autoclave is evenly distributed. The centrifugal impeller fan adopts a direct-drive convection system. The centrifugal impeller fan is directly connected to the mechanical seal and the high-temperature resistant special bearing of Harbin Bearing Group to prevent gas leakage and enable it to work under high-temperature conditions.

[0012] According to the above scheme, the security protection reminders include: The electric heating module and pressurization module can only start heating and pressurizing when the autoclave door is closed and locked, the cooling water flow is normal, and the fan is operating normally. During the operation of the glass autoclave, the safety interlock module provides real-time feedback on the safety status to the PLC core control module. The safety status includes: the autoclave door is closed and locked, the cooling water flow is normal, the fan is operating normally, the internal pressure of the autoclave is normal, and the internal temperature of the autoclave is normal.

[0013] According to the above scheme, the fault alarm includes: The safety interlock module provides real-time feedback of fault alarms to the PLC core control module. The fault alarms include abnormal vessel door closure, abnormal cooling water flow, abnormal fan operation, abnormal internal pressure of the vessel, and abnormal internal temperature of the vessel. When the PLC core control module receives a fault alarm from the safety interlock module, it immediately stops the operation of the glass autoclave. When the fault alarm indicates that the internal pressure of the vessel is too high, the PLC core control module will automatically control the pressure relief; when the fault alarm indicates that the internal temperature of the vessel is too high, the PLC core control module will automatically control the cooling.

[0014] According to the above scheme, the manual control includes manually issuing control commands to the parameters and status of the vessel door, temperature, pressure, and vacuum valve. After receiving the control command issued by the user, the touch screen operation module transmits the control command to the PLC core control module through the network communication module; after receiving the control command, the PLC core control module executes the corresponding operation. The process query allows users to query 30 sets of process parameters stored in the data recording and storage module. Users select query conditions, which include process number and related parameters. The touch screen operation module receives the user's selected query conditions and transmits the query task to the data recording and storage module through the network communication module. After receiving and processing the query task, the data recording and storage module transmits the relevant process parameters to the touch screen operation module for display through the network communication module.

This invention ensures the efficient, automatic, and safe operation of the glass autoclave through PLC control, touch screen operation, real-time data monitoring, and intelligent alarms; 2.

Detailed Implementation

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] Example: Figures 1-3 As shown, the present invention provides a technical solution: a control system for a glass autoclave; The data acquisition module monitors the vessel door opening / closing status, internal vessel temperature, internal vessel pressure, cooling water flow rate, and cooling water inlet / outlet temperature in real time using photoelectric sensors, vessel door status sensors, air temperature thermocouples, high-temperature resistant special pressure sensors, flow meters, and cooling water temperature sensors. The data is then transmitted to the PLC core control module and the data recording and storage module.

[0019] The PLC core control module receives this real-time data, processes it automatically, and then executes control commands, including automatic opening and closing of the vessel door, automatic heating, automatic hot air circulation, automatic pressurization, automatic depressurization, and automatic cooling.

[0020] Before the control command begins, the safety interlock module sends a safety protection reminder to the PLC core control module. The safety protection reminder includes the following: the vessel door is closed and locked, the cooling water flow is normal, the fan is running normally, the internal pressure of the vessel is normal, and the internal temperature of the vessel is normal. Only when the vessel door is closed and locked, the cooling water flow is normal, and the fan is running normally can the electric heating module and the pressurization module start heating and pressurization.

[0021] When there is a workflow or production requirement and glass needs to enter the glass autoclave, the hydraulic system in the quick-opening door module drive device is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the closed position to the open position. At the same time, the toothed flange separates, and the autoclave door is fully opened. When it is detected that the glass has completely entered the glass autoclave, the hydraulic system in the quick-opening door module drive is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the open position to the closed position. At the same time, the toothed flange engages, the autoclave door closes, and the silicone sealing ring is pressed tightly.

[0022] According to the set process parameters, the electric heating module sends a heating control signal to activate the solid-state relay. The solid-state relay controls the current to flow through the nickel-chromium alloy finned heating element, causing the nickel-chromium alloy finned heating element to heat up and ensuring that the internal temperature of the vessel rises to the predetermined value. At the same time, the hot air circulation module sends a hot air circulation control signal, and the centrifugal impeller fan generates forced convection through the centrifugal impeller to send hot air into the U-shaped air duct; the hot air is evenly pushed to the bottom and sides of the vessel through the U-shaped air duct, so that the hot air inside the vessel is evenly distributed and the internal temperature of the vessel is uniform. When the internal temperature of the autoclave rises to the predetermined value, the pressure module controls the pilot solenoid valve to open the pneumatic ball valve, allowing compressed air or steam to enter the glass autoclave and start automatic pressurization, so that the PVB film and glass are evenly bonded. Once the PVB film is fully bonded to the glass and forms a robust laminated glass, the pressure module controls the pilot solenoid valve to open the pneumatic ball valve, initiating automatic pressure relief to reduce the internal pressure of the vessel. Simultaneously, the silencer reduces the noise generated during exhaust.

[0023] Once the set heat preservation time is reached, the heat exchange module controls the flow of cooling water into the surface-cooled finned heat exchanger. As the cooling water flows within the surface-cooled finned heat exchanger, it absorbs heat and carries away the heat inside the vessel, thus automatically reducing the internal temperature of the vessel. After the automatic cooling process is complete, the cooling water is discharged from the drainage structure.

[0024] After the laminated glass is synthesized, the hydraulic system in the quick-opening door module drive device is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the closed position to the open position. At the same time, the toothed flange separates, and the autoclave door is fully opened. When it is detected that the glass has been completely removed from the glass autoclave, the hydraulic system in the quick-opening door module drive is activated. The hydraulic system pushes the swing arm structure of the autoclave door, causing the autoclave door to swing from the open position to the closed position. At the same time, the toothed flange engages, the autoclave door closes, and the silicone sealing ring is pressed tightly.

[0025] During the operation of the glass autoclave, the safety interlock module provides real-time feedback on safety status and fault alarms to the PLC core control module. The fault alarms include abnormal door closure, abnormal cooling water flow, abnormal fan operation, abnormal internal pressure of the autoclave, and abnormal internal temperature of the autoclave. When the PLC core control module receives a fault alarm from the safety interlock module, it immediately stops the operation of the glass autoclave. When the fault alarm indicates that the internal pressure of the vessel is too high, the PLC core control module will automatically control the pressure relief; when the fault alarm indicates that the internal temperature of the vessel is too high, the PLC core control module will automatically control the cooling.

[0026] This invention provides a technical solution: a control system for a glass autoclave; Users can remotely monitor and operate the device through the network communication module and the touch screen operation module. Users can view real-time data and fault alarms of the glass autoclave through the touch screen operation module interface, and complete manual control and process query. The real-time data includes monitoring the opening and closing status of the vessel door, the internal temperature of the vessel, the internal pressure of the vessel, the cooling water flow rate, and the inlet and outlet temperatures of the cooling water; the fault alarm conditions include abnormal vessel door closure, abnormal cooling water flow rate, abnormal fan operation, abnormal internal pressure of the vessel, and abnormal internal temperature of the vessel. The manual control includes manually issuing control commands to the parameters and status of the vessel door, temperature, pressure, and vacuum valve. After receiving the control commands from the user, the touch screen operation module transmits the control commands to the PLC core control module through the network communication module; after receiving the control commands, the PLC core control module executes the corresponding operations. The process query allows users to query 30 sets of process parameters stored in the data recording and storage module. Each of the 30 sets of process parameters is stored in the form of a table, which contains all relevant parameters in each set of process parameters, and each set of process parameters forms a unique process number. The relevant parameters include heating temperature, holding temperature, pressure, heating time, holding time, cooling time, steam flow rate, upper temperature limit, and upper pressure limit.

[0027] The user selects query conditions, which include process number and related parameters; the touch screen operation module receives the user's selected query conditions and transmits the query task to the data recording and storage module through the network communication module; after receiving and processing the query task, the data recording and storage module transmits the relevant process parameters to the touch screen operation module for display through the network communication module.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
