DETAILED DESCRIPTION

[0026] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present disclosure, the schemes of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0028] With reference to Figures 1 to 4 As shown in the figure, the embodiment provides a tire vulcanization system, which comprises a gas storage device 1 adapted to supply and recover a vulcanization medium, a vulcanization capsule 2 adapted to receive or release the vulcanization medium, a gas pipeline 3 adapted to communicate the gas storage device 1 and the vulcanization capsule 2, and a heat exchange device 4 arranged on the gas pipeline 3; wherein,

[0029] The gas pipeline 3 comprises a first gas pipeline 31, a second gas pipeline 32 and a third gas pipeline 33, the gas inlet end of the first gas pipeline 31 is communicated with the gas storage device 1, the gas inlet end of the first gas pipeline 31 is the end of the vulcanization medium entering the first gas pipeline 31 when the tire vulcanization system is used, the gas outlet end of the third gas pipeline 33 is communicated with the gas inlet end of the gas storage device 1, the gas outlet end of the third gas pipeline 33 is the end of the vulcanization medium leaving the third gas pipeline 33 when the tire vulcanization system is used, and the gas inlet end of the gas storage device 1 is the end of the vulcanization medium entering the gas storage device 1 when the tire vulcanization system is used; one end of the second gas pipeline 32 is communicated with the vulcanization capsule 2, and the other end is communicated with the gas outlet end of the first gas pipeline 31 and the gas inlet end of the third gas pipeline 33 through a three-way component 20, respectively, at least part of the second gas pipeline 32 is located in the heat exchange device 4, and the heat exchange device 4 can be a hollow structure so that part of the second gas pipeline 32 passes through the inside of the heat exchange device 4 to exchange heat with the heat exchange device 4;

[0030] Alternatively, the above-mentioned gas pipeline 3 comprises a gas inlet pipeline 34 adapted to deliver the vulcanization medium from the gas storage device 1 to the vulcanization capsule 2 and a gas outlet pipeline 35 adapted to deliver the vulcanization medium from the vulcanization capsule 2 to the gas storage device 1, at least part of the gas inlet pipeline 34 and at least part of the gas outlet pipeline 35 are located in the heat exchange device 4, and specifically, one end of the gas inlet pipeline 34 can be communicated with the gas storage device 1, and the other end can be communicated with the vulcanization capsule 2, one end of the gas outlet pipeline 35 can be communicated with the gas storage device 1, and the other end can be communicated with the vulcanization capsule 2, and at least part of the gas inlet pipeline 34 and the gas outlet pipeline 35 are located in the heat exchange device 4.

[0031] When the venting pipeline 3 comprises a first venting pipeline 31, a second venting pipeline 32 and a third venting pipeline 33, the above three venting pipelines 3 are communicated by the three-way component 20, so that when the vulcanizing medium is input into the vulcanizing capsule 2, the vulcanizing medium enters into the vulcanizing capsule 2 through the first venting pipeline 31 and the second venting pipeline 32, i.e. the second venting pipeline 32 serves as the air inlet pipeline when the vulcanizing medium is input into the vulcanizing capsule 2; when the vulcanizing medium in the vulcanizing capsule 2 is discharged, the vulcanizing medium flows back into the gas storage device 1 through the second venting pipeline 32 and the third venting pipeline 33 in turn, i.e. the second venting pipeline 32 serves as the air outlet pipeline when the vulcanizing capsule 2 is discharged. During the discharging process, the high-temperature vulcanizing medium enters into the second venting pipeline 32, so that the temperature of the wall of the second venting pipeline 32 is increased, and part of the second venting pipeline 32 is located in the heat exchange device 4, which can absorb the heat of the vulcanizing medium in the second venting pipeline 32. When the vulcanizing medium is input into the vulcanizing capsule 2 again, the vulcanizing medium passes through the heat exchange device 4 and the second venting pipeline 32 with higher temperature, and the heat exchange device 4 and the second venting pipeline 32 can both preheat the vulcanizing medium, which can effectively improve the preheating effect of the vulcanizing medium, thereby realizing the recycling and utilization of the heat of the vulcanizing medium discharged from the vulcanizing capsule 2, and saving the energy consumption for heating the input vulcanizing medium in the vulcanizing capsule 2 to the set temperature.

[0032] When the venting pipeline 3 comprises an air inlet pipeline 34 adapted to deliver the vulcanizing medium from the gas storage device 1 to the vulcanizing capsule 2 and an air outlet pipeline 35 adapted to deliver the vulcanizing medium from the vulcanizing capsule 2 to the gas storage device 1, at least part of the air inlet pipeline 34 and at least part of the air outlet pipeline 35 are located in the heat exchange device 4. When the vulcanizing medium is discharged from the vulcanizing capsule 2, at least part of the air outlet pipeline 35 is located in the heat exchange device 4, which can absorb the heat of the vulcanizing medium in the air outlet pipeline 35, thereby increasing the temperature in the heat exchange device 4. When the vulcanizing medium is input into the vulcanizing capsule 2 through the air inlet pipeline 34, the vulcanizing medium with lower temperature enters into the heat exchange device 4 with higher temperature, which can preheat the vulcanizing medium to be input into the vulcanizing capsule 2, thereby realizing the recycling and utilization of the heat of the vulcanizing medium discharged from the vulcanizing capsule 2, and saving the energy consumption for heating the input vulcanizing medium in the vulcanizing capsule 2 to the set temperature.

[0033] The above two modes both realize the effects of recycling and utilizing the heat of the vulcanizing medium discharged from the vulcanizing capsule 2, and preheating the vulcanizing medium to be input into the vulcanizing capsule 2, effectively saving the energy required for the cyclic heating and cooling operation of the vulcanizing medium, and reducing the influence of the device operation on the ambient temperature.

[0034] Referring to Figure 3 and Figure 4As shown, in some embodiments, the heat exchange device 4 comprises a shell 42 and a circulating pump 43, the shell 42 is formed with a heat exchange cavity 41, and the heat exchange cavity 41 is provided with a heat conducting medium, and the liquid inlet and the liquid outlet of the circulating pump 43 are communicated with both ends of the heat exchange cavity 41.

[0035] Specifically, the heat exchange cavity 41 can be filled with heat conducting oil as the heat conducting medium. When the venting pipeline 3 has the vulcanizing medium discharged from the vulcanizing capsule 2, the temperature of the venting pipeline 3 rises, and the heat of the venting pipeline 3 located in the heat exchange cavity 41 is absorbed by the heat conducting oil, so that the temperature of the heat conducting oil rises, and the temperature of the discharged vulcanizing medium in the venting pipeline 3 is reduced. Due to the rise in the temperature of the heat conducting oil, when the vulcanizing medium is input into the vulcanizing capsule through the venting pipeline 3, the heat of the heat conducting oil is absorbed by the venting pipeline 3 located in the heat exchange cavity 41, so that the vulcanizing medium to be input into the vulcanizing capsule 2 is heated, thereby realizing the preheating of the vulcanizing medium.

[0036] In addition, by arranging the circulating pump 43, the circulating pump 43 is communicated with the heat exchange cavity 41, so that the heat conducting medium can flow circularly under the action of the circulating pump 43, and the temperature of the heat conducting medium is more uniform, thereby improving the heat absorption effect of the heat conducting medium on the vulcanizing medium discharged from the vulcanizing capsule 2 and the preheating effect of the heat conducting medium on the vulcanizing medium to be input into the vulcanizing capsule 2, and thereby improving the heat exchange efficiency between the venting pipeline 3 and the heat exchange device 4.

[0037] Referring to Figure 4 As shown, in some embodiments, the heat exchange device 4 further comprises an inlet pipeline suitable for communicating the liquid inlet of the circulating pump 43 with the heat exchange cavity 41, and an outlet pipeline suitable for communicating the liquid outlet of the circulating pump 43 with the heat exchange cavity 41, and the inlet pipeline and / or the outlet pipeline is provided with a heating assembly 45.

[0038] The above-mentioned inlet pipeline and outlet pipeline are arranged to communicate the circulating pump 43 with the heat exchange cavity 41, and the heating assembly 45 is arranged on the inlet pipeline and / or the outlet pipeline to heat the heat conducting medium, thereby improving the preheating effect of the heat exchange device 4 on the vulcanizing medium to be input into the vulcanizing capsule 2.

[0039] The above-mentioned heating assembly 45 can specifically comprise an electric resistance wire.

[0040] Referring to Figure 3 and Figure 4 As shown, in some embodiments, the shell 42 comprises a shell inner wall and a shell outer wall, and a heat preservation layer 44 is arranged between the shell inner wall and the shell outer wall.

[0041] Specifically, fireproof cotton can be selected to fill between the shell inner wall and the shell outer wall as the heat preservation layer 44, of course, heat preservation gel can also be selected to fill between the shell inner wall and the shell outer wall as the heat preservation layer 44, or the shell inner wall and the shell outer wall can be in a vacuum state.

[0042] By setting the heat preservation layer 44 between the inner wall of the shell and the outer wall of the shell, the heat loss of the heat conducting medium in the heat exchange cavity 41 is reduced, thereby ensuring the preheating effect of the vulcanizing medium entering the vulcanizing capsule 2. In the heat exchange device 4 provided with the heating assembly 45, the energy consumption of the heating assembly 45 can also be reduced by reducing the heat loss of the heat conducting medium.

[0043] Referring to Figure 1 As shown in FIG. 1, in some embodiments, two stop valves are arranged on the first vent pipe 31, and a check valve 6 and a diaphragm regulating valve 7 are arranged in sequence along the flow direction of the vulcanizing medium between the two stop valves. Specifically, the two stop valves can be a pneumatic stop valve 8 and a manual stop valve 5, that is, the manual stop valve 5, the check valve 6, the diaphragm regulating valve 7 and the pneumatic stop valve 8 are arranged in sequence along the flow direction of the vulcanizing medium on the first vent pipe 31. Figure 1 The arrow direction in FIG. 1 is the flow direction of the vulcanizing medium, which enters the vulcanizing capsule 2 from the gas storage device 1 through the first vent pipe 31 and the second vent pipe 32, and then returns to the gas storage device 1 from the vulcanizing capsule 2 through the second vent pipe 32 and the third vent pipe 33.

[0044] The opening direction of the check valve 6 is along the flow direction of the vulcanizing medium, which prevents the vulcanizing medium in the vulcanizing capsule 2 from flowing back to the gas storage device 1. The diaphragm regulating valve 7 is used to control the flow and pressure of the vulcanizing medium in the first vent pipe 31. Since the pressure in the gas storage device 1 is relatively high, the pressure of the vulcanizing medium needs to be reduced before entering the vulcanizing capsule 2, that is, the diaphragm regulating valve 7 plays a role in reducing the pressure of the vulcanizing medium entering the vulcanizing capsule 2, so as to achieve the required pressure for the vulcanization reaction and avoid excessive pressure of the vulcanizing medium affecting the tire vulcanization. The pneumatic stop valve 8 can be remotely controlled to open and close. After the pneumatic stop valve 8 is closed, the vulcanizing medium can be accumulated in the vulcanizing capsule 2, so as to ensure that the pressure of the vulcanizing medium participating in the vulcanization reaction is maintained within a predetermined range. The manual stop valve 5 is close to the gas storage device 1 and is used to manually control the opening and closing of the first vent pipe 31. When the system is in a running state, the manual stop valve 5 remains in a conductive state. At the same time, the manual stop valve 5 can also play the role of a safety device. When the pneumatic stop valve 8 fails or the tire vulcanization system is being maintained, the opening and closing of the first vent pipe 31 can be manually controlled.

[0045] By arranging the manual stop valve 5, the check valve 6, the diaphragm regulating valve 7 and the pneumatic stop valve 8 in sequence along the flow direction of the vulcanizing medium on the first vent pipe 31, the worker can control the flow and movement direction of the vulcanizing medium in the first vent pipe 31, thereby improving the safety of the tire vulcanization system during operation.

[0046] Referring to Figure 1As shown, in some embodiments, two stop valves are arranged on the third vent pipe 33, and an air-water separator 9, a check valve 6 and an air compressor 10 are arranged in sequence along the flow direction of the curing medium between the two stop valves. Specifically, the two stop valves on the third vent pipe 33 can be a manual stop valve 5 and a pneumatic stop valve 8, that is, the pneumatic stop valve 8, the air-water separator 9, the check valve 6, the air compressor 10 and the manual stop valve 5 are arranged in sequence along the flow direction of the curing medium on the third vent pipe 33.

[0047] The air-water separator 9 described above mainly functions to remove the water in the curing medium in the curing capsule 2, and the purified curing medium is introduced into the gas storage device 1. The air compressor 10 can provide driving force for the movement of the curing medium in the vent pipe 3. The opening direction of the check valve 6 is along the flow direction of the curing medium, and the check valve 6 can effectively prevent the backflow of the curing medium. The pneumatic stop valve 8 is arranged close to the curing capsule 2, and can be closed during the tire curing work to make the curing medium stay in the curing capsule 2 to participate in the tire curing work, thereby avoiding the discharge of the curing medium.

[0048] By arranging the pneumatic stop valve 8, the air-water separator 9, the check valve 6, the air compressor 10 and the manual stop valve 5 in sequence along the flow direction of the curing medium on the third vent pipe 33, the staff can control the flow rate and pressure of the curing medium in the third vent pipe 33, and the curing medium can be purified by the air-water separator 9, so that the curing medium can be input into the gas storage device 1 for recycling.

[0049] In addition, a stop valve is arranged between the heat exchange device 4 and the curing capsule 2, and specifically, the stop valve can be a pneumatic stop valve 8. When the pressure of the curing medium in the curing capsule 2 reaches a preset value, the pneumatic stop valve 8 is closed, so that the curing medium can stay in the curing capsule 2 to participate in the tire curing work.

[0050] In the above embodiment, the first vent pipe 31, the second vent pipe 32 and the third vent pipe 33 are provided, and the three vent pipes 3 are communicated by the three-way component 20, so that when the vulcanizing medium is input into the vulcanizing capsule 2, the second vent pipe 32 serves as the gas inlet pipe; when the vulcanizing medium in the vulcanizing capsule 2 is discharged, the second vent pipe 32 serves as the gas outlet pipe. During the gas discharge process, the high-temperature vulcanizing medium enters the second vent pipe 32, so that the temperature of the wall of the second vent pipe 32 rises, and part of the second vent pipe 32 is located in the heat exchange cavity 41, and the heat-conducting medium in the heat exchange cavity 41 can absorb the heat of the vulcanizing medium in the second vent pipe 32. When the vulcanizing medium is input into the vulcanizing capsule 2 again, the vulcanizing medium passes through the heat exchange device 4 and the second vent pipe 32 with a higher temperature, and the heat exchange device 4 and the second vent pipe 32 can preheat the vulcanizing medium, which can effectively improve the preheating effect of the vulcanizing medium, thereby realizing the recovery of the heat of the vulcanizing medium discharged from the vulcanizing capsule 2, and saving the energy consumption for heating the input vulcanizing medium in the vulcanizing capsule 2 to the set temperature.

[0051] Referring to Figure 2 As shown in FIG. 1, in some embodiments, two stop valves are arranged on the gas inlet pipe 34, and a check valve 6 and a diaphragm regulating valve 7 are arranged in sequence along the flow direction of the vulcanizing medium between the two stop valves. The above two stop valves can be a manual stop valve 5 and a pneumatic stop valve 8, that is, the gas inlet pipe 34 is sequentially provided with the manual stop valve 5, the check valve 6, the diaphragm regulating valve 7 and the pneumatic stop valve 8 along the flow direction of the vulcanizing medium. Part of the gas inlet pipe 34 between the check valve 6 and the diaphragm regulating valve 7 is located in the heat exchange cavity 41, or part of the gas inlet pipe 34 between the diaphragm regulating valve 7 and the pneumatic stop valve 8 is located in the heat exchange cavity 41. Figure 2 The arrow direction in FIG. 1 indicates the flow direction of the vulcanizing medium, that is, the flow direction of the vulcanizing medium is from the gas storage device 1 to the vulcanizing capsule 2 through the gas inlet pipe 34, and then from the vulcanizing capsule 2 to the gas storage device 1 through the gas outlet pipe 35.

[0052] The opening direction of the check valve 6 is along the flow direction of the curing medium, which can avoid the backflow of the curing medium. The diaphragm regulating valve 7 can control the flow and pressure of the curing medium in the air passage 3. Since the pressure in the air storage device 1 is relatively high, the pressure of the curing medium needs to be reduced before entering the curing bladder 2, that is, the diaphragm regulating valve 7 plays a role in reducing the pressure of the curing medium entering the curing bladder 2 to achieve the required pressure for the vulcanization reaction. The pneumatic stop valve 8 can be remotely controlled to open and close. After the pneumatic stop valve 8 is closed, the curing medium can stay in the curing bladder 2 to ensure that the pressure of the curing medium participating in the vulcanization reaction is maintained within a predetermined range. The manual stop valve 5 is close to the air storage device 1 and is used to manually control the opening and closing of the air inlet pipeline 34. When the system is in operation, the manual stop valve 5 remains in the on state. At the same time, the manual stop valve 5 also serves as a safety device and can manually control the opening and closing of the air inlet pipeline 34 when the pneumatic stop valve 8 fails.

[0053] By sequentially arranging the manual stop valve 5, the check valve 6, the diaphragm regulating valve 7 and the pneumatic stop valve 8 on the air inlet pipeline 34 along the flow direction of the curing medium, the operator can control the flow and movement direction of the curing medium in the air inlet pipeline 34, thereby improving the safety of the tire vulcanization system during tire vulcanization.

[0054] Referring to Figure 2 In some embodiments, two stop valves are arranged on the exhaust pipeline 35, and a gas-water separator 9, a check valve 6 and an air compressor 10 are sequentially arranged between the two stop valves along the flow direction of the curing medium. The two stop valves can be a manual stop valve 5 and a pneumatic stop valve 8, that is, the pneumatic stop valve 8, the gas-water separator 9, the check valve 6, the air compressor 10 and the manual stop valve 5 are sequentially arranged on the exhaust pipeline 35 along the flow direction of the curing medium. The part of the exhaust pipeline 35 between the pneumatic stop valve 8 and the gas-water separator 9 is located in the heat exchange cavity 41. The gas-water separator 9 mainly functions to remove the water in the curing medium in the curing bladder 2. The air compressor 10 compresses the curing medium in the air passage 3 to provide driving force for the movement of the curing medium. The opening direction of the check valve 6 is along the flow direction of the curing medium. The pneumatic stop valve 8 is arranged close to the curing bladder 2 and can ensure the pressure of the curing medium remaining in the curing bladder 2 during tire vulcanization to ensure the effect of the vulcanization reaction.

[0055] The pneumatic stop valve 8, the air-water separator 9, the check valve 6, the air compressor 10 and the manual stop valve 5 are sequentially arranged on the exhaust pipeline 35 along the flow direction of the vulcanizing medium, so that the staff can control the flow rate and pressure of the vulcanizing medium in the exhaust pipeline 35, and the vulcanizing medium can be purified by the air-water separator 9. The heat exchange cavity 41 arranged between the pneumatic stop valve 8 and the air-water separator 9 can avoid the high-temperature vulcanizing medium entering the air-water separator 9, affecting the normal work of the air-water separator 9, and the vulcanizing medium will lose the heat carried after passing through the air-water separator 9, reducing the working efficiency of the heat exchange device 4.

[0056] Referring to Figure 1 and Figure 2 In some embodiments, the number of heat exchange devices 4 is multiple, and the multiple heat exchange devices 4 are arranged adjacent and in series. Among the multiple heat exchange devices 4, at least the heat exchange device 4 close to the vulcanizing capsule 2 is provided with a heating assembly 45 to heat the heat-conducting medium in the heat exchange device 4. Specifically, three heat exchange devices 4 can be arranged on the air pipeline 3, and the three heat exchange devices 4 are adjacent and in series. Of course, other numbers of heat exchange devices 4 can also be arranged on the air pipeline 3.

[0057] By arranging multiple heat exchange devices 4, the heat exchange is sufficient while the loss in the heat exchange process is reduced, which can effectively improve the heat absorption effect of the vulcanizing medium discharged from the vulcanizing capsule and the preheating effect of the vulcanizing medium to be entered into the vulcanizing capsule 2, avoids additional cooling of the vulcanizing medium discharged from the vulcanizing capsule 2, and effectively improves the overall heat exchange efficiency of the system. When the multiple heat exchange devices 4 are arranged in series on the air pipeline 3, the heat exchange device 4 close to the vulcanizing capsule 2 can be selected as the heat exchange device 4 with the heating assembly 45, the heat exchange device 4 away from the vulcanizing capsule 2 can be selected as the heat exchange device 4 without the heating assembly 45, and the remaining heat exchange devices 4 can be selected as the heat exchange device 4 with or without the heating assembly 45 according to the heat exchange effect of the vulcanizing medium in the air pipeline 3, so as to gradually increase the temperature of the heat-conducting medium in the heat exchange device 4 in the direction gradually close to the vulcanizing capsule 2, realize gradient heat exchange, ensure effective heat absorption of the vulcanizing medium discharged from the vulcanizing capsule 2, improve the preheating effect of the vulcanizing medium to be entered into the vulcanizing capsule 2, improve the preheating temperature of the vulcanizing medium to be entered into the vulcanizing capsule 2, and reduce the required energy consumption for heating the vulcanizing medium in the vulcanizing capsule 2.

[0058] For example, the number of heat exchange devices 4 is three, and the heat exchange device 4 close to the vulcanization capsule 2 is provided with a heating assembly 45, and the other two heat exchange devices 4 are not provided with the heating assembly 45. The temperature of the heat transfer medium in the heat exchange device 4 provided with the heating assembly 45 is lower than the temperature of the vulcanization medium discharged from the vulcanization capsule 2, so as to ensure the heat absorption and cooling effect of the heat exchange device 4 on the discharged vulcanization medium. At the same time, the heating assembly 45 can effectively increase the temperature of the heat transfer medium, so as to increase the temperature of the vulcanization medium to be introduced into the vulcanization capsule 2, thereby improving the preheating effect of the vulcanization medium. The vulcanization medium discharged from the vulcanization capsule 2 passes through the heat exchange devices with and without the heating assembly 45 in turn, forming gradient heat exchange, and effectively improving the heat exchange effect of the system.

[0059] In addition, the vent pipe 3 located in the heat exchange cavity 41 is spiral-shaped, so as to improve the heat exchange effect.

[0060] By arranging a plurality of heat exchange devices 4 on the vent pipe 3, the plurality of heat exchange devices 4 are adjacent and connected in series, so as to avoid that when the vulcanization medium flows in the vent pipe 3, the heat exchange with one heat exchange device 4 is insufficient due to the fast moving speed, and the heat carried by the vulcanization medium is lost in the environment, that is, the plurality of adjacent and connected heat exchange devices 4 can realize multi-stage heat exchange of the vulcanization medium, prolong the residence time of the vulcanization medium in the heat exchange cavity 41, and make the vulcanization medium and the heat exchange device 4 fully exchange heat.

[0061] In addition, the vulcanization capsule 2 is provided with a heater and a turbulence component in the present application, the turbulence component can be a fan, the vulcanization medium can be inert gas such as nitrogen, and the vulcanization medium provides the pressure and heat required for tire vulcanization during the vulcanization process.

[0062] In specific use, open the hand-operated stop valve 5, the pneumatic stop valve 8 and the diaphragm regulating valve 7 on the first vent pipe 31 or the air inlet pipe 34, and make the vulcanizing medium enter the vulcanizing capsule 2 from the gas storage device 1 through the first vent pipe 31 or the air inlet pipe 34 for vulcanization. Wherein, open the diaphragm regulating valve 7, so that the vulcanizing medium enters the vulcanizing capsule 2 with proper pressure, and close the pneumatic stop valve 8 on the first vent pipe 31 or the air inlet pipe 34 when the vulcanizing capsule 2 is filled with the vulcanizing medium. After the vulcanization is completed, open the pneumatic stop valve 8 on the second vent pipe 32 or the air outlet pipe 35, and the vulcanizing medium is discharged from the vulcanizing capsule 2 and exchanges heat with the heat exchange device 4, so that the vulcanizing medium is cooled from the vulcanizing medium with higher temperature in the vulcanizing capsule 2 to the vulcanizing medium with lower temperature, and then the vulcanizing medium with lower temperature enters the gas-water separator 9 for purification, and the purified vulcanizing medium enters the gas storage device 1 through the third vent pipe 33 or the air outlet pipe 35 for recycling. At the same time, the vulcanizing medium discharged from the vulcanizing capsule 2 exchanges heat with the heat exchange device 4, so that the temperature of the heat-conducting medium in the heat exchange device 4 is increased, so as to preheat the vulcanizing medium to be entered into the vulcanizing capsule 2, wherein the hand-operated stop valve 5 is always open, and is closed during system maintenance.
