Description

Technical Field

[0001] This application relates to the technical field of tire vulcanization power, and particularly to an unattended tire vulcanization medium supply system. Background Art

[0002] Tire vulcanization is the last and most crucial process in tire manufacturing. It transforms the plastic rubber with a linear polymer structure having viscoelasticity in the tire into a network polymer material by pressurizing and heating inside the mold and bladder, thereby improving the strength and elasticity of the tire.

However, the traditional tire vulcanization system has a low degree of automation. It not only relies on the operator's experience to adjust the operating parameters of the tire vulcanization system, resulting in low control accuracy for tire vulcanization, but also requires someone to be on duty 24 hours a day.

[0055] An embodiment of this application provides an unattended vulcanization medium supply system 10 for tires. The unattended vulcanization medium supply system 10 for tires can cooperate with a tire vulcanizer 20 to ensure the normal progress of tire vulcanization. Among them, the tire vulcanizer 20 can be used for the vulcanization of tires and can also be used for the vulcanization of vehicle tires. Before vulcanization, the tire blank can be first placed in a mold with a certain contour and with patterns. During vulcanization, steam can heat the tire blank through the mold, and at the same time, superheated water enters the bladder of the tire vulcanizer 20 according to the pressure required for vulcanization, providing the pressure and heat required for vulcanization.

[0056] As Figure 1 shown, the unattended vulcanization medium supply system 10 for tires includes a superheated water subsystem 200, an internal pressure cooling water subsystem 300, a vacuum pumping subsystem 400 and an unattended control subsystem 100. Among them, the superheated water subsystem 200 is used to convey superheated water at a preset temperature and a preset pressure to the vulcanization bladder, providing the heat and pressure required for tire vulcanization, and the superheated water subsystem 200 is provided with a first valve assembly 210 and a first sensing assembly 220.

[0057] The internal pressure cooling water subsystem 300 is used to convey cooling water to the vulcanized tire to cool the tire, and is provided with a second valve assembly 310 and a second sensing assembly 320. Among them, the quality of the cooling water can be softened water, and the temperature is set to normal temperature.

[0058] The vacuum pumping subsystem 400 is used to pump vacuum on the curing bladder after curing so as to make the curing bladder shrink, which is convenient for taking out the cured tire and reinstalling the next tire blank. The vacuum pumping subsystem 400 is provided with a third sensing component 410 and a third valve component 490.

[0059] The unattended control subsystem 100 is electrically connected to the first valve component 210 and the first sensing component 220 to control the operation of the superheated water subsystem 200; it is also electrically connected to the second valve component 310 and the second sensing component 320 to control the operation of the internal pressure cooling water subsystem 300; it is also electrically connected to the third sensing component 410 and the third valve component 490 to control the operation of the vacuum pumping subsystem 400. As an example, the unattended control subsystem 100 can be a DCS (Distributed Control System) control system. The unattended control subsystem 100 is also equipped with an industrial control computer for monitoring and reserves standard interfaces, which can realize data interaction with various remote monitoring systems or realize the group control function of multiple devices.

[0060] Through the signal interaction with the first valve component 210 and the first sensing component 220 on the superheated water subsystem 200, the unattended control subsystem 100 can automatically control the operation of the superheated water subsystem 200; through the signal interaction with the second valve component 310 and the second sensing component 320 of the internal pressure cooling water subsystem 300, it can automatically control the internal pressure cooling water subsystem 300; through the signal interaction with the third sensing component 410 and the third valve component 490 on the vacuum pumping subsystem 400, it can automatically control the vacuum pumping subsystem 400. This enables the operation of the entire unattended tire curing medium supply system 10 to be automatically adjusted, without relying on the experience of operators to adjust the operation parameters of the unattended tire curing medium supply system 10, which can ensure the control accuracy of tire curing and does not require operators to be on duty 24 hours a day.

[0061] Such as Figure 2As shown, in some embodiments, the superheated water subsystem 200 includes a high-pressure deaerating heater 230, a steam supply pipeline 241, and a superheated water filling pipeline 242; the high-pressure deaerating heater 230 is provided with a first pressure sensor 221 electrically connected to the unattended control subsystem 100; the steam supply pipeline 241 communicates with a first inlet of the high-pressure deaerating heater 230 and is provided with a first pressure regulating valve 211 electrically connected to the unattended control subsystem 100, and the unattended control subsystem 100 is configured to adjust the opening degree of the first pressure regulating valve 211 based on the feedback of the first pressure sensor 221; the superheated water filling pipeline 242 communicates with a first outlet of the high-pressure deaerating heater 230 and is provided with a superheated water filling pump 251, a first electric switch valve 218, and a second pressure sensor 222, all of which are electrically connected to the unattended control subsystem 100. The first electric switch valve 218 and the second pressure sensor 222 are located downstream of the superheated water filling pump 251. The unattended control subsystem 100 is configured to adjust the frequency of the superheated water filling pump 251 and open or close the first electric switch valve 218 based on the feedback of the second pressure sensor 222; wherein, the first valve assembly 210 includes the first pressure regulating valve 211 and the first electric switch valve 218, and the first sensing assembly 220 includes the first pressure sensor 221 and the second pressure sensor 222.

[0062] The superheated water subsystem 200 of the present application adopts a direct-contact high-pressure deaerating heater 230, which integrates deaeration and heating. Compared with the indirect heating method for preparing superheated water, it makes more full use of steam heat energy and reduces heat loss. The high-pressure deaerating heater 230 uses saturated steam for heating, and the temperature of the saturated steam corresponds to the pressure. The high-pressure deaerating heater 230 controls the temperature of the deaerated water by adjusting the pressure of the steam pipeline, so that the temperature of the superheated water processed by the high-pressure deaerating heater 230 is controlled between 160°C and 170°C. For this purpose, the present application sets a first pressure sensor 221 on the high-pressure deaerating heater 230 and a first pressure regulating valve 211 on the steam supply pipeline 241, and uses the first pressure sensor 221 to monitor the pressure inside the high-pressure deaerating heater 230. Once the pressure fluctuates, the unattended control subsystem 100 adjusts the opening degree of the first pressure regulating valve 211 according to the feedback of the first pressure sensor 221 to adjust the steam pressure, and the control accuracy can be ±0.05 Mpa.

[0063] Optionally, as Figure 2 shown, the steam supply pipeline 241 is provided with a first bypass 2411, and the first bypass 2411 is provided with a first stop valve 2412. The first stop valve 2412 is arranged in parallel with the first pressure regulating valve 211. When the first pressure regulating valve 211 is under maintenance, the first stop valve 2412 can be opened so that steam can be delivered into the high-pressure deaerating heater 230 to ensure the normal operation of the tire unattended vulcanization medium supply system 10.

[0064] In addition, in order to convey superheated water with a preset pressure to the vulcanizer 20, the present application further provides a superheated water filling pump 251 and a first pressure sensor 222 on the superheated water filling pipeline 242. The second pressure sensor 222 is used to monitor the outlet water pressure of the superheated water filling pump 251. Once the outlet water pressure fluctuates, the unattended control subsystem 100 adjusts the frequency of the superheated water filling pump 251 according to the feedback of the second pressure sensor 222 to adjust the outlet water pressure of the superheated water filling pump 251, so that the superheated water filling pipeline 242 can convey superheated water with a preset pressure to the vulcanizer 20. In addition, if the outlet water pressure of the hot water filling pump 251 is too high or too low, the unattended control subsystem 100 can also correspondingly close or open the hot water filling pump 251 by closing or opening the first electric switch valve 218.

[0065] Optionally, as Figure 2 shown, a plurality of superheated water filling pumps 251 are provided, and the plurality of superheated water filling pumps 251 are arranged in parallel. The superheated water subsystem 200 further includes a first changeover switch 281. The first changeover switch 281 has a plurality of first paths. The unattended control subsystem 100 is used to conduct or cut off the first paths to make the corresponding superheated water filling pumps 251 energized or de-energized. Among them, the conduction states of the plurality of first paths are not synchronized. When the current superheated water filling pump 251 fails, the first changeover switch 281 can automatically stop the currently failed superheated water filling pump 251 and enable other standby superheated water filling pumps 251, so as to ensure the normal operation of the tire unattended vulcanization medium supply system 10. Among them, the number of superheated water filling pumps 251 can be set accordingly according to requirements without specific limitation. For example Figure 2 shown, there are 2.

[0066] Furthermore, as Figure 2 shown, in an embodiment, the superheated water subsystem 200 further includes a circulating superheated water supply pipeline 243 and a circulating superheated water return pipeline 244. During vulcanization, the superheated water can continuously circulate through the circulating superheated water supply pipeline 243 and the circulating superheated water return pipeline 244 until the vulcanization ends, which can save water resources.

[0067] Among them, the superheated water supply pipeline 243 is connected to the second outlet of the high-pressure deaerating heater 230, and is provided with a superheated water circulation pump 252, a second electric switch valve 219 and a third pressure sensor 223, all of which are electrically connected to the unattended control subsystem 100. The third pressure sensor 223 and the second electric switch valve 219 are located downstream of the superheated water circulation pump 252. The unattended control subsystem 100 is used to adjust the frequency of the superheated water circulation pump 252 and open or close the second electric switch valve 219 based on the feedback of the third pressure sensor 223. The third pressure sensor 223 is used to monitor the outlet water pressure of the superheated water circulation pump 252. Once the outlet water pressure fluctuates, the unattended control subsystem 100 adjusts the frequency of the superheated water circulation pump 252 according to the feedback of the third pressure sensor 223 to adjust the outlet water pressure of the superheated water circulation pump 252, so that the superheated water supply pipeline 243 can supply superheated water with a preset pressure to the vulcanizer 20. If the outlet water pressure of the superheated water circulation pump 252 is too high or too low, the unattended control subsystem 100 can also close or open the second electric switch valve 219 to correspondingly close or open the superheated water circulation pump 252.

[0068] Optionally, as Figure 2 shown, multiple superheated water circulation pumps 252 are provided, and the multiple superheated water circulation pumps 252 are arranged in parallel. The superheated water subsystem 200 further includes a second transfer switch 282. The second transfer switch 282 has multiple second paths. The unattended control subsystem 100 is used to conduct or cut off the second paths to make the corresponding superheated water circulation pumps 252 energized or de-energized. Among them, the conduction states of the multiple second paths are not synchronized. When the current superheated water circulation pump 252 fails, the second transfer switch 282 can automatically stop the current faulty superheated water circulation pump 252 and enable other standby superheated water circulation pumps 252, so as to ensure the normal operation of the tire unattended vulcanization medium supply system 10. Among them, the number of the superheated water circulation pumps 252 can be set accordingly according to requirements, without specific limitation. For example Figure 2 shown, there are 2.

[0069] Optionally, as Figure 2 shown, the superheated water subsystem 200 further includes a sampling pipeline 246. The sampling pipeline 246 is connected to the superheated water supply pipeline 243 and is located upstream of the superheated water circulation pump 252. The sampling pipeline 246 is provided with a sampling cooler 247. The superheated water in the high-pressure deaerating heater 230 can be sampled after being cooled by the sampling cooler 247 to detect the water quality.

[0070] The circulating superheated water return pipeline 244 is connected to the second inlet of the high-pressure deaerating heater 230, and is provided with a second pressure regulating valve 212 and a fourth pressure sensor 224 both electrically connected to the unattended control subsystem 100. The second pressure regulating valve 212 is located downstream of the fourth pressure sensor 224. The unattended control subsystem 100 is used to adjust the opening degree of the second pressure regulating valve 212 based on the feedback of the fourth pressure sensor 224. Among them, the first valve assembly 210 further includes a second pressure regulating valve 212 and a second electric shut-off valve 219, and the first sensing assembly 220 further includes a third pressure sensor 223 and a fourth pressure sensor 224. After the circulating superheated water return flows out of the vulcanizer 20, the fourth pressure sensor 224 is used to monitor the pressure of the circulating superheated water return. If the pressure of the circulating superheated water return is too high or too low, the unattended control subsystem 100 will correspondingly adjust the opening degree of the second pressure regulating valve 212 based on the feedback of the fourth pressure sensor 224 to control the pressure of the circulating superheated water return within a safe range, thus avoiding damage to the high-pressure deaerating heater 230.

[0071] Optionally, as Figure 2 shown, the circulating superheated water return pipeline 244 is provided with a second bypass 2441, and a second stop valve 2442 is provided on the second bypass 2441. The second stop valve 2442 is arranged in parallel with the second pressure regulating valve 212. When the second pressure regulating valve 212 is being repaired, the second stop valve 2442 can be opened so that the circulating superheated water return can be transported into the high-pressure deaerating heater 230 to ensure the normal operation of the tire unattended vulcanization medium supply system 10.

[0072] Optionally, as Figure 2 shown, the circulating superheated water return pipeline 244 is connected to the superheated water filling pipeline 242 through a first branch pipeline 2443. The first branch pipeline 2443 is provided with an eighth stop valve 2444. The upstream end of the first branch pipeline 2443 is located downstream of the superheated water filling pump 251, and the downstream end of the first branch pipeline 2443 is located downstream of the second pressure regulating valve 212. When the pumping flow rate of the superheated water filling pump 251 is too large, a part of the superheated water can flow back into the high-pressure deaerating heater 230 through the first branch pipeline 2443.

[0073] Optionally, as Figure 2 shown, a first filter 2445 is provided on the circulating superheated water return pipeline 244, and the first filter 2445 is located upstream of the fourth pressure sensor 224. The first filter 2445 can filter the circulating superheated water return. Among them, multiple first filters 2445 can be arranged in parallel.

[0074] Continue to refer to Figure 2, in one embodiment, the superheated water subsystem 200 further includes a waste heat recovery tank 260 and a deaerator overflow water pipeline 245; the high-pressure deaeration heater 230 is further provided with a first liquid level sensor 225 electrically connected to the unattended control subsystem 100; the deaerator overflow water pipeline 245 connects the third outlet of the high-pressure deaeration heater 230 to the inlet of the waste heat recovery tank 260, and is provided with a first switch valve 213 electrically connected to the unattended control subsystem 100. When the water level in the high-pressure deaeration heater 230 is higher than the first preset water level, the unattended control subsystem 100 can open the first switch valve 213, and when the water level in the high-pressure deaeration heater 230 is lower than the second preset water level, the unattended control subsystem 100 can close the first switch valve 213; wherein, the first valve assembly 210 further includes the first switch valve 213, and the first sensing assembly 220 further includes the first liquid level sensor 225. The water level of the high-pressure deaeration heater 230 can be monitored by the first liquid level sensor 225. If it is higher than the first preset water level, the unattended control subsystem 100 will open the first switch valve 213 to overflow the superheated water in the high-pressure deaeration heater 230 into the waste heat recovery tank 260 until the water level in the high-pressure deaeration heater 230 is lower than the first preset water level.

[0075] Wherein, the unattended control subsystem 100 further has an alarm function, and an alarm will be issued once the water level in the high-pressure deaeration heater 230 is higher than the first preset water level or lower than the second preset water level.

[0076] Further, as Figure 2 shown, in one embodiment, the waste heat recovery tank 260 has an atmospheric pressure hot water area 260a and a clean water area 260b. The first inlet of the waste heat recovery tank 260 in the atmospheric pressure hot water area 260a is connected to the deaerator overflow water pipeline 245. The waste heat recovery tank 260 is provided with a second liquid level sensor 226 in the atmospheric pressure hot water area 260a and a third liquid level sensor 227 in the clean water area 260b; the superheated water subsystem 200 further includes a deaerator makeup water pipeline 261, a clean water outlet pipeline 263 and a clean water makeup pipeline 264.

[0077] Among them, the make-up water pipeline 261 of the deaeration tank is connected to the third inlet of the high-pressure deaeration heater 230 and the first outlet of the waste heat recovery tank 260 in the normal pressure hot water area 260a, and is provided with a normal pressure hot water pump 271 electrically connected to the unattended control subsystem 100. When the water level in the normal pressure hot water area 260a is higher than the fifth preset water level, the normal pressure hot water pump 271 is turned on to send the hot water in the normal pressure hot water area 260a back to the high-pressure deaeration heater 230 for recycling. When the water level in the normal pressure hot water area 260a is lower than the sixth preset water level, the normal pressure hot water pump 271 is turned off. The second liquid level sensor 226 can be used to monitor the water level in the normal pressure hot water area 260a. Once the water level in the normal pressure hot water area 260a is higher than the fifth preset water level, the unattended control subsystem 100 supplies power to the normal pressure hot water pump 271 and turns on the normal pressure hot water pump 271 to pump the normal pressure hot water in the normal pressure hot water area 260a of the waste heat recovery tank 260 into the high-pressure deaeration heater 230 through the make-up water pipeline 261 of the deaeration tank until the water level in the normal pressure hot water area 260a is lower than the fifth preset water level.

The high-temperature normal pressure water discharge pipeline 295 can discharge the residual high-temperature normal pressure water after vulcanization of the vulcanizer 20 to the normal pressure hot water area 260a of the waste heat recovery tank 260.

[0079] Optionally, as Figure 2 shown, the superheated water subsystem 200 further includes a first water collecting tank 291. The second outlet of the waste heat recovery tank 260 in the normal pressure hot water area 260a is connected to a first sewage pipeline, and the first sewage pipeline extends into the first water collecting tank 291.

When the water level in the clean water area 260b is higher than the seventh preset water level, the second switching valve 215 opens to discharge the excess hot water in the clean water area 260b. When the water level in the clean water area 260b is lower than the eighth preset water level, the second switching valve 215 closes. When the water level of the high-pressure deaerating heater 230 is lower than the third preset water level, the third switching valve 2100 opens to replenish water to the high-pressure deaerating heater 230. When the water level of the high-pressure deaerating heater 230 is higher than the fourth preset water level, the third switching valve 2100 closes. The third liquid level sensor 227 is used to detect the water level in the clean water area 260b. Once the water level in the clean water area 260b is higher than the seventh preset water level, the unattended control subsystem 100 opens the clean water pump 272 and the second switching valve 215, and the clean water in the clean water area 260b is sent back to the boiler room through the clean water outlet pipeline 263 for replenishing water to the high-pressure deaerating heater 230 or sent back to the tire embryo storage.

[0081] The clean water make-up pipeline 264 is connected to the first inlet of the waste heat recovery tank 260 in the clean water area 260b, and is provided with a fourth switching valve 216 electrically connected to the unattended control subsystem 100. When the water level in the clean water area 260b is lower than the ninth preset water level, the fourth switching valve 216 opens. When the water level in the clean water area 260b is higher than the tenth preset water level, the fourth switching valve 216 closes. Among them, the first valve assembly 210 further includes the second, third and fourth switching valves, and the first sensing assembly 220 further includes the second and third liquid level sensors. The third liquid level sensor 227 is used to detect the water level in the clean water area 260b. Once the water level in the clean water area 260b is lower than the ninth preset water level, the unattended control subsystem 100 opens the fourth switching valve 216, and the clean water flows into the clean water area 260b from the workshop pipeline for water replenishment.

[0082] Optionally, as Figure 2 shown, the clean water make-up pipeline 264 is provided with a fourth bypass 2641, and a fourth stop valve 2642 is provided on the fourth bypass 2641.

[0083] Optionally, as Figure 2 shown, the superheated water subsystem 200 further includes a second water collecting tank 292. The second outlet of the waste heat recovery tank 260 in the clean water area 260b is connected to a second sewage pipeline, and the second sewage pipeline extends into the second water collecting tank 292. The sewage in the clean water area 260b can be discharged into the second water collecting tank 292.

[0084] Optionally, as Figure 2 shown, the superheated water subsystem 200 further includes a steam condensate water circuit 293 and a return water pipe 294 of the embryo library. The steam condensate water circuit 293 and the return water pipe 294 of the embryo library are respectively communicated with the second inlet and the third inlet of the waste heat recovery tank 260 in the clean water area 260b. When the water level in the clean water area 260b is lower than the seventh preset water level, the steam condensate water in the vulcanizer 20 can be supplemented into the clean water area 260b through the steam condensate water circuit 293, and the return water of the embryo library can also be supplemented into the clean water area 260b through the return water pipe 294 of the embryo library.

[0085] Continue to refer to Figure 2 , the waste heat recovery tank 260 is also provided with a first temperature sensor 228 in the clean water area 260b; the superheated water subsystem 200 further includes a heating pipeline 265. The heating pipeline 265 is communicated with the steam supply pipeline 241 and extends into the clean water area 260b, and is provided with a first temperature regulating valve 217 electrically connected to the unattended control subsystem 100. When the water temperature in the clean water area 260b is lower than the first preset temperature, the first temperature regulating valve 217 is opened, and when the water temperature in the clean water area 260b reaches the second preset temperature, the first temperature regulating valve 217 is closed; wherein, the first valve assembly 210 further includes the first temperature regulating valve 217, and the first sensing assembly 220 further includes the first temperature sensor. The water temperature in the clean water area 260b can be monitored by using the first temperature sensor 228. Once the water temperature in the clean water area 260b is lower than the first preset temperature, the unattended control subsystem 100 opens the first temperature regulating valve 217, so that the high-temperature steam in the steam supply pipeline 241 flows into the clean water area 260b through the heating pipeline 265, thereby increasing the water temperature in the clean water area 260b. Once the water temperature in the clean water area 260b reaches the second preset temperature, the first temperature regulating valve 217 is closed.

[0086] Optionally, as Figure 2 shown, the superheated subsystem further includes a steam condensate water pipeline 293. The steam condensate water pipeline 293 is communicated with the steam supply pipeline 241 and the clean water area 260b. The steam condensate water pipeline 293 is located upstream of the first pressure regulating valve 211, and a steam trap 2933 is provided on the steam condensate water pipeline 293. The steam trap 2933 can discharge the condensate water in the steam into the clean water area 260b. Wherein, the steam condensate water pipeline 293 is provided with a fifth bypass 2931, and a fifth stop valve 2932 is provided on the fifth bypass 2931. The fifth stop valve 2932 is arranged in parallel with the steam trap 2933. When the steam trap is being repaired, the fifth stop valve 2932 can be opened to ensure the normal operation of the tire unattended vulcanization medium supply system 10.

[0087] Of course, the steam condensate water pipeline 293 can also be arranged on the heating pipeline 265.

[0088] As Figure 3 shown, in some embodiments, the internal pressure cooling water subsystem 300 includes an internal cooling water tank 330, a high-temperature cooling tower 340, an internal cooling water make-up pipeline 331, an internal cooling water supply pipeline 332, a circulating internal cooling water return pipeline 341, and a cooling tower outlet pipeline 342. The internal cooling water in the internal cooling water tank 330 can be conveyed into the vulcanizer 20 through the internal cooling water supply pipeline 332 to cool the cord ply of the tire. When cooling the tire, the temperature of the internal cooling water in the vulcanizer 20 will rise. Therefore, the internal cooling water in the vulcanizer 20 flows back to the high-temperature cooling tower 340 through the circulating internal cooling water return pipeline 341 for cooling, and the cooled internal cooling water then flows into the internal cooling water tank 330 through the cooling tower outlet pipeline 342 for cyclic cooling use.

[0089] Among them, the internal cooling water supply pipeline 332 is provided with an internal cooling water pump 350 electrically connected to the unattended control subsystem 100. After the tire vulcanization is completed, the unattended control subsystem 100 supplies power to the internal cooling water pump 350, and the internal cooling water pump 350 pumps the internal cooling water in the internal cooling water tank 330 into the vulcanizer 20 to cool the cord ply of the tire.

[0090] As Figure 3 shown, the internal cooling water supply pipeline 332 is further provided with a fifth pressure sensor 323 and a third electric switch valve 313 that are electrically connected to the unattended control subsystem 100. The fifth pressure sensor 323 and the third electric switch valve 313 are arranged downstream of the internal cooling water pump 350. The unattended control subsystem 100 is used to adjust the frequency of the internal cooling water pump 350 and open or close the third electric switch valve 313 based on the feedback of the fifth pressure sensor 323. The fifth pressure sensor 323 is used to monitor the outlet water pressure of the internal cooling water pump 350. Once the outlet water pressure fluctuates, the unattended control subsystem 100 adjusts the frequency of the internal cooling water pump 350 according to the feedback of the fifth pressure sensor 323 to adjust the outlet water pressure of the internal cooling water pump 350, so that the internal cooling water supply pipeline 332 can convey cold water with a preset pressure to the vulcanizer 20. In addition, if the outlet water pressure of the internal cooling water pump 350 is too high or too low, the unattended control subsystem 100 can also correspondingly close or open the internal cooling water pump 350 by closing or opening the third electric switch valve 313.

[0091] Optionally, as Figure 3As shown, multiple internal cooling water pumps 350 are provided, and the multiple internal cooling water pumps 350 are arranged in parallel. The internal pressure cooling water subsystem 300 further includes a third transfer switch 370. The third transfer switch 370 has multiple third paths. The unattended control subsystem 100 is used to conduct or cut off the third paths so that the corresponding internal cooling water pumps 350 are powered on or off. Among them, the conduction states of the multiple third paths are not synchronized. When the current internal cooling water pump 350 fails, the currently failed internal cooling water pump 350 can be automatically stopped through the third transfer switch 370, and other standby internal cooling water pumps 350 can be enabled, thereby ensuring the normal operation of the tire unattended vulcanization medium supply system 10. Among them, the number of the internal cooling water pumps 350 can be set accordingly according to requirements, without specific limitation. For example Figure 3 the 2 shown in

[0092] The internal cooling water tank 330 is provided with a fourth liquid level sensor 321 electrically connected to the unattended control subsystem 100. The internal cooling water make-up pipeline 331 is provided with a fifth switching valve 311 electrically connected to the unattended control subsystem 100. When the water level in the internal cooling water tank 330 is lower than the eleventh preset water level, the fifth switching valve 311 is opened, and when the water level in the internal cooling water tank 330 is higher than the twelfth preset water level, the fifth switching valve 311 is closed. The fourth liquid level sensor 321 is used to monitor the water level in the internal cooling water tank 330. Once the water level in the internal cooling water tank 330 is lower than the eleventh preset water level, the unattended control subsystem 100 opens the fifth switching valve 311, and the internal cooling water in the workshop pipeline is replenished into the internal cooling water tank 330.

[0093] Optionally, the internal cooling water make-up pipeline 331 is provided with a sixth bypass 3311. A sixth stop valve 3312 is provided on the sixth bypass 3311. The sixth stop valve 3312 is arranged in parallel with the fifth switching valve 311. When the fifth switching valve 311 is under maintenance, the sixth stop valve 3312 can be opened to ensure the normal operation of the tire unattended vulcanization medium supply system 10.

[0094] Optionally, the internal pressure cooling water subsystem 300 further includes a third water collecting tank 360.

[0095] The return pipe 341 of the circulating internal cooling water is provided with a sixth pressure sensor 322 and a third pressure regulating valve 312 both electrically connected to the unattended control subsystem 100. The third pressure regulating valve 312 is located downstream of the sixth pressure sensor 322. The unattended control subsystem 100 is used to adjust the opening degree of the third pressure regulating valve 312 based on the feedback of the sixth pressure sensor 322. Among them, the second valve assembly 310 includes a fifth on-off valve 311, a third pressure regulating valve 312 and a third electric on-off valve 313, and the second sensing assembly 320 includes a fourth liquid level sensor 321, a fifth pressure sensor 323 and a sixth pressure sensor 322. The sixth pressure sensor 322 is used to monitor the pressure of the circulating internal cooling water return. Once the pressure of the circulating internal cooling water return is too large or too small, the unattended control subsystem 100 correspondingly adjusts the opening degree of the third pressure regulating valve 312, thereby controlling the pressure of the circulating internal cooling water return within a safe range, and the control accuracy can be as high as ±0.05 MPa.

[0096] Optionally, the return pipe 341 of the circulating internal cooling water is provided with a seventh bypass 3411. A seventh stop valve 3412 is provided on the seventh bypass 3411. The seventh stop valve 3412 is arranged in parallel with the third pressure regulating valve 312. When the third pressure regulating valve 312 is under maintenance, the seventh stop valve 3412 can be opened to ensure the normal operation of the tire unattended vulcanization medium supply system 10.

[0097] Optionally, multiple high-temperature cooling towers 340 are arranged in parallel. In this way, the cooling effect of the high-temperature cooling tower 340 on the circulating internal cooling water return can be increased. Regarding the number of high-temperature cooling towers 340, it can be set accordingly according to the situation, for example Figure 3 as shown, 2.

[0098] The cooling tower outlet pipe 342 connects the inlet of the internal cooling water tank 330 and the outlet of the high-temperature cooling tower 340.

[0099] Of course, the internal cooling water make-up pipe 331 can also be connected to the high-temperature cooling tower 340 through a second branch pipe 343. The high-temperature cooling tower 340 can be supplemented with internal cooling water.

[0100] As Figure 3 shown, in some embodiments, the vacuum pumping subsystem 400 includes a vacuum tank 420, a vacuum pumping recovery water tank 430 and a vacuum pump 440 electrically connected to the unattended control subsystem 100. The vacuum tank 420 serves as a buffer tank. The upper area is vacuum and the lower area is water. When the vacuum pump 440 is started, the air in the vulcanization capsule in the vulcanizer 20 is pumped out by the vacuum pump 440 through the upper area of the vacuum tank 420. Among them, when the vacuum pump 440 is operating, cooling water needs to be supplied to the vacuum pump 440 for water sealing, and then the cooling water is recovered into the vacuum pumping recovery water tank 430.

The internal pressure cooling water subsystem 400 further includes a fourth switching switch 480, and the fourth switching switch 480 has multiple fourth passages. The unattended control subsystem 100 is configured to conduct or cut off the fourth passages so that the corresponding vacuum pumps 440 are powered on or off. Among them, the conduction states of the multiple fourth passages are not synchronized. When the current vacuum pump 440 fails, the current faulty vacuum pump 440 can be automatically stopped through the fourth switching switch 480, and other standby vacuum pumps 440 can be enabled, thereby ensuring the normal operation of the tire unattended vulcanization medium supply system 10. Regarding the number of vacuum pumps 440, corresponding settings are made according to requirements. For example Figure 3 As shown, there are 2.

The seventh pressure sensor 413 is used to monitor the gas pressure at the air inlet of the vacuum pump 440. Once the gas pressure at the air inlet fluctuates, the unattended control subsystem 100 adjusts the frequency of the vacuum pump 440 according to the feedback of the seventh pressure sensor 413 to adjust the gas pressure at the air inlet of the vacuum pump 440, so as to stably evacuate the vacuum for the vulcanizer 20. In addition, if the gas pressure at the air inlet of the vacuum pump 440 is too high or too low, the unattended control subsystem 100 can also close or open the vacuum pump 440 by closing or opening the fourth electric switch valve 491.

[0106] The vacuum tank 420 is provided with a fifth liquid level sensor 411 electrically connected to the unattended control subsystem 100. The vacuum tank return water pipeline 421 communicates with the liquid outlet of the vacuum tank 420 and is provided with a vacuum tank return water pump 450 electrically connected to the unattended control subsystem 100. When the water level in the vacuum tank 420 is higher than the thirteenth preset water level, the vacuum tank return water pump 450 is turned on, and when the water level in the vacuum tank 420 is lower than the fourteenth preset water level, the vacuum tank return water pump 450 is turned off. The fifth liquid level sensor 411 is used to monitor the water level in the vacuum tank 420. Once the water level in the vacuum tank 420 is higher than the thirteenth preset water level, the unattended control subsystem 100 energizes the vacuum tank return water pump 450, and the vacuum tank return water pump 450 pumps out the water in the vacuum tank 420 (for example, pumps it into the normal pressure hot water area 260a of the waste heat recovery tank 260) until the water level in the vacuum tank 420 is lower than the thirteenth preset water level.
