[0038] The embodiments of the application are described below with reference to the drawings of the embodiments of the application. The terms used in the implementation manner part of the embodiments of the application are only used to explain the specific embodiments of the application, and are not intended to limit the application.

[0039] First, the autoclave cooling circulation system provided by the embodiment of the application is introduced, please refer to Figure 1 .

[0040] Figure 1 The autoclave cooling circulation system provided by the embodiments of the present application can have one or multiple autoclaves, and the embodiments of the present application do not particularly limit the number of autoclaves. Figure 1 The number of autoclaves is taken as an example of two.

[0041] As shown in Figure 1 The autoclave cooling circulation system comprises a first cooling system and a second cooling system for cooling the autoclaves.

[0042] The first cooling system comprises a first cooling tower 11, a first water pump 121 and a first water circulation pipeline; and the second cooling system comprises a water storage pool 21, an ice-water main machine 22, a second cooling tower 23, a second water pump 241, a second water circulation pipeline and a third water circulation pipeline.

[0043] The autoclave 30, the first cooling tower 11 and the first water pump 121 are connected to each other through the first water circulation pipeline to form a first cooling loop; and the first water pump 121 is configured to drive the cooling water to circulate in the first cooling loop to cool the autoclave 30.

[0044] The autoclave 30, the first water pump 121 and the water storage pool 21 are connected to each other through the second water circulation pipeline to form a second cooling loop; and the first water pump 121 is further configured to drive the water in the water storage pool 21 to circulate in the second cooling loop to cool the autoclave 30.

[0045] The water storage pool 21, the ice-water main machine 22, the second cooling tower 23 and the second water pump 241 are connected to each other through the third water circulation pipeline to form a third cooling loop; and the second water pump 241 is configured to drive the water in the water storage pool 21 to circulate in the third cooling loop to cool the water in the water storage pool 21.

[0046] The first water circulation pipeline can comprise a first water outlet pipe 131 and a first water inlet pipe 132; and the second water circulation pipeline can comprise a second water outlet pipe 251 and a second water inlet pipe 252.

[0047] For each autoclave 30, the water inlet and the water outlet can each comprise one or more; in some embodiments, the first water circulation pipeline can be connected to one water inlet and one water outlet of the autoclave 30, and the second water circulation pipeline can be connected to another water inlet and another water outlet of the autoclave 30.

[0048] In some embodiments, the first water circulation pipeline and the second water circulation pipeline can share one water inlet and one water outlet of the autoclave 30 to simplify the connection structure.

[0049] Specifically, the water outlet of the autoclave 30 is connected with the water inlet of the first cooling tower 11 through the first water outlet pipe 131, and the second water outlet pipe 251 is connected between the first water outlet pipe 131 and the first water inlet of the water storage pool 21.

[0050] The water outlet of the first cooling tower 11 is connected with the water inlet of the autoclave 30 through the first water inlet pipe 132, and the first water pump 121 is arranged on the first water inlet pipe 132; one end of the second water inlet pipe 252 is connected between the first cooling tower 11 and the first water pump 121, and the other end of the second water inlet pipe 252 is connected with the first water outlet of the water storage pool 21.

[0051] The first water outlet pipe 131, the first water inlet pipe 132 between the first cooling tower 11 and the first water pump 121, the second water outlet pipe 251, and the second water inlet pipe 252 are all provided with a switch valve, that is, the switch valve 1, the switch valve 2, the switch valve 3, and the switch valve 4 shown in FIG. 1. Figure 1

[0052] The switch valve can be a disc valve, and specifically can be an electric butterfly valve or a dual-purpose butterfly valve capable of being controlled electrically and manually, so as to improve the flexibility of the switch control.

[0053] It can be understood that in some embodiments, the switch valve can also be other valves such as a ball valve, which is not particularly limited in the embodiment.

[0054] The first cooling tower 11 can be built-in with a water pool, or can be externally connected with a water pool on the first cooling tower 11 or the first water pump 121 to provide cooling water, and the built-in water pool of the first cooling tower 11 is exemplarily described below.

[0055] The third water circulation pipeline can include a third water outlet pipe 261 and a third water inlet pipe 262.

[0056] Specifically, one end of the third water outlet pipe 261 is connected with the second water outlet of the water storage pool 21, and the other end of the third water outlet pipe 261 is connected with the water inlet of the second cooling tower 23 through the ice-water main machine 22; one end of the third water inlet pipe 262 is connected with the water outlet of the second cooling tower 23, and the other end of the third water inlet pipe 262 is connected with the second water inlet of the water storage pool 21 through the ice-water main machine 22; the second water pump 241 is arranged on the third water outlet pipe 261 between the ice-water main machine 22 and the second cooling tower 23. A third water pump 271 can also be arranged on the third water outlet pipe 261 between the second water outlet of the water storage pool 21 and the ice-water main machine 22, so as to improve the flow power of the water flow between the second water outlet of the water storage pool 21 and the ice-water main machine 22, so that the backwater passing through the ice-water main machine 22 can more smoothly enter the water storage pool 21.

[0057] ​In the above implementation, the water cooled by the second cooling tower 23 can pass through the ice-water host 22 again, so that the cooling effect can be improved.

[0058] In some embodiments, one of the third water outlet pipe 261 and the third water inlet pipe 262 can also not pass through the ice-water host 22, so that the third water pump 271 does not need to be connected, thereby simplifying the pipeline structure.

[0059] It can be understood that in the above connection relationship, the positional relationship of the first water pump 121, the second water pump 241 and the third water pump 271 can be changed. For example, in the case where the height of the water inlet and outlet of the autoclave 30 is lower than the height of the water inlet and outlet of the first cooling tower 11, the first water pump 121 can also be arranged on the first water outlet pipe 131, so that the water flowing out of the autoclave 30 after heat exchange can more smoothly enter the first cooling tower 11; similarly, in the case where the height of the water inlet and outlet of the ice-water host 22 is higher than the height of the water inlet and outlet of the second cooling tower 23, the second water pump 241 can also be arranged on the third water inlet pipe 262, so that the water cooled by the second cooling tower 23 can more smoothly flow back into the ice-water host 22; similarly, in the case where the height of the water inlet and outlet of the ice-water host 22 is lower than the height of the water inlet and outlet of the water storage tank 21, the third water pump 271 can also be arranged on the third water inlet pipe 262, so that the water cooled by the ice-water host 22 can more smoothly flow back into the water storage tank 21.

[0060] Next, taking the structure of the first cooling system and the second cooling system shown in Figure 1 as an example, the working principle of the first cooling system and the second cooling system is explained.

[0061] When the first cooling system is used to cool the autoclave 30, the on-off valve 1 and the on-off valve 2 are opened, and the on-off valve 3 and the on-off valve 4 are closed. The corresponding first cooling circuit can be seen in the circuit shown by arrow 1 in Figure 1 . The water in the first cooling tower 11 enters the autoclave 30 for heat exchange under the action of the first water pump 121, and the water in the autoclave 30 after heat exchange flows out of the water outlet of the autoclave 30 and enters the first cooling tower 11 for cooling. The water cooled by the first cooling tower 11 enters the autoclave 30 under the action of the first water pump 121, and the cycle is repeated. The water in the first cooling tower 11 continuously exchanges the heat in the autoclave 30, thereby achieving the cooling of the autoclave 30.

[0062] When the second cooling system is used to cool the autoclave 30, the on-off valve 1 and the on-off valve 2 are closed, and the on-off valve 3 and the on-off valve 4 are opened. Correspondingly, the second cooling circuit can be seen in Figure 1The water in the water storage pool 21 enters the autoclave 30 under the action of the first water pump 121 to exchange heat, and the water that has exchanged heat with the autoclave 30 flows out of the water outlet of the autoclave 30 and enters the water storage pool 21, so as to circulate repeatedly, so that the water in the water storage pool 21 continuously exchanges heat from the autoclave 30, thereby achieving the cooling of the autoclave 30.

[0063] The third cooling loop can be seen from the loop shown by the arrow 3 in Figure 1 The water in the water storage pool 21 enters the ice-water host 22 under the action of the third water pump 271 to be cooled for the first time, and the water that has been cooled for the first time enters the second cooling tower 23 under the action of the second water pump 241 to be cooled for the second time. The water that has been cooled for the second time flows out of the water outlet of the second cooling tower 23 under the action of the second water pump 241, passes through the ice-water host 22 again, and returns to the water storage pool 21, so as to circulate repeatedly, thereby achieving the cooling of the water in the water storage pool 21.

[0064] When the autoclave is cooled, the first cooling loop can be used to cool the autoclave when the temperature reaches the first temperature threshold. When the temperature decreases to the second temperature threshold, the first cooling loop is closed, and the second cooling loop and the third cooling loop are used to cool the autoclave. When the temperature decreases to the third temperature threshold, the second cooling loop and the third cooling loop are closed, and the cooling of the autoclave is ended.

[0065] The first temperature threshold can be 138°C, for example, or other temperature values. The second temperature threshold can be 85°C or other temperature values (lower than the first temperature threshold). The third temperature threshold can be 40°C or other temperature values (lower than the second temperature threshold).

[0066] In some embodiments, the autoclave cooling circulation system can further include a bearing cooling pump 311 and a fourth water circulation pipeline, the autoclave 30, the water storage pool 21, and the bearing cooling pump 311 are connected to each other through the fourth water circulation pipeline to form a fourth cooling loop. The bearing cooling pump 311 is used to drive the water in the water storage pool 21 to circulate in the fourth cooling loop to cool the bearing of the autoclave 30.

[0067] When the bearing of the autoclave 30 is cooled, the corresponding fourth cooling loop can be seen from the loop shown by the arrow 4 in Figure 1 The water in the water storage pool 21 enters the autoclave 30 under the action of the bearing cooling pump 311 to exchange heat with the bearing of the autoclave, and the water that has exchanged heat with the bearing of the autoclave flows out of the water outlet of the autoclave 30 and returns to the water storage pool 21, so as to circulate repeatedly, thereby achieving the cooling of the bearing of the autoclave.

[0068] In some embodiments, the first water pump 121, the second water pump 241, the third water pump 271 and / or the bearing cooling pump 311 can be connected in parallel with a standby water pump, i.e. Figure 1 The standby first water pump 122, the standby second water pump 242, the standby third water pump 272 and the standby bearing cooling pump 312 shown in FIG. 1 are connected in parallel with the first water pump 121, the second water pump 241, the third water pump 271 and the bearing cooling pump 311, so that when a water pump fails, the autoclave cooling circulation system can continue to work through its standby water pump, thereby improving the system reliability.

[0069] In addition, a switch valve can also be provided at both ends of each water pump and standby water pump to protect the water pump and prevent water backflow from damaging the pump. Figure 1 In the embodiment shown in FIG. 1, the first water pump 121, the standby first water pump 122, the second water pump 241 and the standby second water pump 242 each have one switch valve, and the third water pump 271 and the standby third water pump 272, the bearing cooling pump 311 and the standby bearing cooling pump each have two switch valves.

[0070] In some embodiments, the autoclave cooling circulation system can further include a controller (not shown) connected with the first cooling system and the second cooling system, and the working states of the first cooling system and the second cooling system can be controlled through the controller.

[0071] Specifically, the working states of the first cooling system and the second cooling system, the water pumps, the first cooling tower 11, the second cooling tower 23 and the switch valves can be controlled through the controller, so as to control the working states of the first water circulation pipeline and the second water circulation pipeline.

[0072] The controller can control the working states of the first cooling system and the second cooling system under the triggering operation of the staff, or automatically detect and control the working states of the first cooling system and the second cooling system, for example, can automatically detect the temperature of the autoclave 30, and control the working states of the first cooling system and the second cooling system according to the detected temperature. Correspondingly, a sensor or other detector can also be provided in the autoclave cooling circulation system to detect the temperature and other state parameters.

[0073] In some embodiments, an alarm or other indicator can also be provided in the autoclave cooling circulation system, and the controller can indicate the working states of the autoclave cooling circulation system to the staff through the indicator.

[0074] The autoclave cooling circulation system can further include a display (not shown) connected with the controller, which can be used to display the working states of the first cooling system and the second cooling system.

[0075] Specifically, the working states of the first cooling system and the second cooling system can be displayed in the form of text and / or graphical interface.

[0076] In some embodiments, the controller can also control the display to display a control interface including a plurality of control options in response to the first operation, and control the working state of the first cooling system or the second cooling system according to a second operation acting on the control options.

[0077] The first operation can be a control operation of a mechanical button by the worker, and the controller is connected with the mechanical button. When the autoclave cooling circulation system fails, the worker can perform the first operation to trigger the controller to control the display to display the control interface.

[0078] In some embodiments, in order to improve convenience, a virtual button can also be displayed on the display, and correspondingly, the first operation can be an operation of the worker acting on the virtual button.

[0079] Exemplarily, as shown in Figure 2 , Figure 2 The interface schematic diagram of the control page provided by the embodiments of the present application is shown. When the first operation is detected, the controller can respond to the operation to control the display to display the control interface, and the control interface can include control options corresponding to the first water pump, the backup first water pump, the second water pump, the backup second water pump, the third water pump, the backup third water pump, the bearing cooling pump, the backup bearing cooling pump, the first cooling tower, the second cooling tower, the ice water host, the on-off valve 1, the on-off valve 2, the on-off valve 3, and the on-off valve 4. The worker can click the above-mentioned control options (i.e. the second operation) to make the controller control the corresponding equipment / on-off valve to be opened or closed, so as to control the working state of the first cooling system or the second cooling system. In this way, automatic control and manual control of the autoclave cooling circulation system can be realized, thereby improving the flexibility of system control.

[0080] In some embodiments, the display can also display other function options in the above-mentioned control interface or other interfaces, for example, control options for controlling the first cooling loop, the second cooling loop, and / or the third cooling loop can be displayed, and the worker can open or close the corresponding cooling loop through the control options.

[0081] The autoclave cooling circulation system provided by the embodiments of the present application can form the first cooling loop, the second cooling loop, and the third cooling loop. In this way, when the autoclave is cooled, the first cooling loop can be used to cool the autoclave once, and then the second cooling loop and the third cooling loop can be used to cool the autoclave twice. Compared with one-time water circulation cooling, the cooling speed of the autoclave can be effectively improved, and in turn, the production quality and production efficiency of the SGP film laminated glass can be improved.

[0082] The embodiments of the present application also provide a control method of an autoclave cooling circulation system, Figure 3A flowchart of a control method of a high-pressure kettle cooling circulation system provided by the embodiments of the present application is shown in the figure. The execution subject of the method can be the controller described in the above embodiments or other electronic devices. The following is an exemplary description taking the execution subject as the controller. Figure 3 The method can include the following steps:

[0083] S11. In a case where it is detected that the temperature of the high-pressure kettle reaches a first temperature threshold, the first cooling loop is controlled to work.

[0084] The temperature of the high-pressure kettle can be detected by a temperature sensor installed on the high-pressure kettle.

[0085] As described above, the first temperature threshold can be 138℃ or other values, which are not particularly limited in the embodiments of the present application. The following is an exemplary description taking the first temperature threshold as 138℃.

[0086] Specifically, in a case where it is detected by the temperature sensor that the current temperature in the high-pressure kettle is 138℃, the first cooling loop is controlled to work. Referring to the loop shown by arrow 1 in Figure 1 The water in the first cooling tower 11 enters the high-pressure kettle 30 to exchange heat under the action of the first water pump 121. The water in the high-pressure kettle 30 after heat exchange flows out from the water outlet of the high-pressure kettle 30 and enters the first cooling tower 11 to be cooled. The water cooled by the first cooling tower 11 enters the high-pressure kettle 30 under the action of the first water pump 121, and so on. The water in the first cooling tower 11 continuously exchanges the heat in the high-pressure kettle 30, so as to cool the high-pressure kettle 30.

[0087] S12. In a case where it is detected that the temperature of the high-pressure kettle decreases to a second temperature threshold, the first cooling loop is closed, and the second cooling loop and the third cooling loop are controlled.

[0088] As described above, the second temperature threshold can be 85℃ or other values, which are not particularly limited in the embodiments of the present application. The following is an exemplary description taking the second temperature threshold as 85℃.

[0089] As an optional embodiment, the second cooling loop can be controlled to work for a period of time before the third cooling loop is controlled to work.

[0090] As another optional embodiment, the second cooling loop and the third cooling loop can be controlled to work together to improve the cooling speed of the high-pressure kettle.

[0091] Specifically, in a case where it is detected by the temperature sensor that the current temperature in the high-pressure kettle is 85℃, the controller can control the second cooling loop to work. Referring to the loop shown by arrow 2 in Figure 1The water in the water pool 21 enters the autoclave 30 for heat exchange under the action of the first water pump 121, and the water after heat exchange with the autoclave 30 flows out of the water outlet of the autoclave 30, enters the water pool 21, and so on, so that the water in the water pool 21 continuously exchanges the heat in the autoclave 30, and the cooling of the autoclave 30 is realized.

[0092] In addition, the controller can control the third cooling loop to work. Referring to the loop shown by the arrow 3 in Figure 1 The water in the water pool 21 enters the ice-water host 22 for first cooling under the action of the third water pump 271, the water after first cooling enters the second cooling tower 23 under the action of the second water pump 241, the second cooling tower 23 performs second cooling, the water after second cooling flows out of the water outlet of the second cooling tower 23 under the action of the second water pump 241, and then passes through the ice-water host 22 to return to the water pool 21, so as to realize the cooling of the water in the water pool 21.

[0093] In some embodiments, since the water temperature of the water pool 21 is relatively low in winter, the third cooling loop can not be started to work to cool the water in the water pool 21; in summer, since the external temperature is high, the water temperature of the water pool 21 is relatively high, and at this time, the third cooling loop can be started to work to cool the water in the water pool, so as to accelerate the cooling speed of the autoclave.

[0094] S13, after detecting that the temperature of the autoclave decreases to a third temperature threshold, the second cooling loop and the third cooling loop are closed.

[0095] The third temperature threshold can be 40℃, or other values, and the embodiments of the present application do not particularly limit this, and the third temperature threshold is taken as 40℃ in the subsequent example.

[0096] Specifically, when the sensor detects that the temperature of the autoclave decreases to 40℃, it indicates that the temperature in the autoclave can meet the requirements, at this time, the second cooling loop and the third cooling loop can be closed, and the cooling process of the autoclave is ended.

[0097] It should be noted that in addition to controlling the first cooling system and the second cooling system to work, the controller can also control the fourth cooling loop to work to cool the bearing of the autoclave.

[0098] Specifically, referring to the loop shown by the arrow 4 in Figure 1Arrow 4 indicates that the water in the water storage tank 21 enters the pressure vessel 30 under the action of the bearing cooling pump 311 to exchange heat with the pressure vessel bearing. After heat exchange with the pressure vessel bearing, the water flows out from the outlet of the pressure vessel 30 and returns to the water storage tank 21. This cycle repeats to cool the pressure vessel bearing.

[0099] Correspondingly, when the temperature sensor detects that the current temperature inside the autoclave is 40°C, the controller can also shut down the fourth cooling circuit, ending the cooling process of the autoclave's bearings.

[0100] As an optional implementation, the control method may further include, for example: Figure 4 The steps shown are as follows:

[0101] S21. In response to the first operation, a control interface including multiple control options is displayed.

[0102] Specifically, in the event of a malfunction in the aforementioned autoclave cooling circulation system, such as the first water pump 121 failing to operate, an alarm can be triggered. Upon hearing the alarm, personnel can manually access the control interface (e.g., ...) through the first operation. Figure 2 (As shown).

[0103] S22, In response to a second operation acting on the control option, control the operating state of the first cooling system or the second cooling system according to the second operation.

[0104] like Figure 2 As shown, the control interface includes multiple control options, which operators can click to control the corresponding equipment / switching valve to open or close.

[0105] For example, if the first water pump 121 fails, the operator can select the control option "backup first water pump", and the autoclave cooling circulation system can start the backup first water pump 122 to continue the cooling process of the autoclave.

[0106] As an alternative implementation, in the event of a failure of the first water pump 121, the valve of the first water pump can be manually shut off, and then the valve of the backup first water pump 122 can be opened to allow the autoclave cooling circulation system to continue operating.

[0107] The control method is similar when other components malfunction, and will not be described in detail here.

[0108] Figure 5 Electrical schematic diagram of the autoclave cooling circulation system provided in the embodiments of this application.

[0109] like Figure 5As shown, the power line L1 and the power line L2 are connected to the power port of the PLC, for supplying power to the programmable logic controller (PLC) and providing power to each device in the autoclave cooling circulation system.

[0110] SA1 is a single-pole double-throw switch, in the non-closed state, the autoclave cooling circulation system is in an automatic running state, and in the closed state, the autoclave cooling circulation system is in a manual control state; SB1-SB2 are button switches, according to the state of SA1, SB1 and SB2 are closed or turned off accordingly. One end of SA1, SB1 and SB2 is connected to the corresponding port X0-X2 of the PLC, and the other end is connected to the power line L3.

[0111] The PLC controls each device to work by sending corresponding control signals, so as to maintain the operation of the autoclave cooling circulation system.

[0112] It can be understood that, Figure 5 The figure only shows the electrical connection diagram of part of the devices in the autoclave cooling circulation system, and other devices in the autoclave cooling circulation system, such as the switch valve 1-switch valve 4, can also be connected between the power line and the corresponding port of the PLC.

[0113] In addition, the PLC can also be implemented by other processors, and the above only shows part of the electrical principle, and other devices can also be connected to the PLC to realize more functions, such as alarm function, overload detection function, etc., which are not particularly limited in the embodiment.

[0114] The control method of the autoclave cooling circulation system provided by the embodiment of the application first controls the first cooling circuit to cool the autoclave once, and then controls the second cooling circuit and the third cooling circuit to cool the autoclave twice, which can effectively improve the cooling speed of the autoclave, and thus is conducive to improving the production quality and production efficiency of the SGP film laminated glass.
