The vulcanization method using nitrogen as the vulcanization medium usually heats the nitrogen by electric heating. About 60% of the energy consumption in the vulcanization workshop is consumed during the operation of the vulcanization system. Therefore, how to reduce the energy consumption in the tire vulcanization system and apply renewable new energy to the tire vulcanization system to meet the requirements of energy conservation and environmental protection has become a strong competitive direction in tire production.

[0020] Figure 2 It is a schematic diagram of a vulcanization system with a new energy heating element and an electric heating element arranged in parallel according to the present invention. DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0022] See attached Figures 1 to 2As shown, the present invention discloses a tire vulcanization system 1 (hereinafter referred to as vulcanization system) having a solar heating unit for heating an inert gas vulcanization medium, comprising a mold 10 for detachably accommodating a green tire (not shown), and a capsule 20 arranged inside the green tire during vulcanization operation, wherein the capsule 20 is provided with a capsule air inlet 21 and a capsule air outlet 22; a medium circulation device 30 for circulating the inert gas vulcanization medium (hereinafter referred to as vulcanization medium) is provided, wherein the medium circulation device 30 can be any device that can circulate the vulcanization medium, such as a fan, a blower or a circulation pump; and The capsule air inlet pipeline 40 is connected to the capsule air inlet 21, and the capsule air outlet pipeline 50 is connected to the capsule air outlet 22. The medium circulation device 30 is connected to the capsule air inlet pipeline 40 and the capsule air outlet pipeline 50 respectively; it also includes an air charging pipeline 60 connected to the capsule air inlet pipeline 40, and an exhaust pipeline 70 connected to the capsule air outlet pipeline 50, the air charging pipeline 60 is used to supply the vulcanization medium to the vulcanization system, and the exhaust pipeline 70 is used to recover or discharge the vulcanization medium in the vulcanization system; the capsule air inlet pipeline 40 is provided with a solar heating unit 80 for heating the vulcanization medium. Through the above arrangement, in the green tire vulcanization operation, the vulcanization medium is heated by the solar heating unit 80, so as to make full use of solar energy resources, thereby reducing the consumption of non-renewable energy and reducing carbon emissions.

[0023] The solar heating unit 80 of the present invention comprises a solar power generation device 81 and a solar heating element 82 connected to the solar power generation device, wherein the solar heating element 82 is arranged on the capsule air inlet pipeline 40. The above arrangement realizes the use of solar energy.

[0024] It should be noted that the solar power generation device 81 of the present invention can be directly connected to the solar heating element 82, so that the vulcanization system can directly use the direct current converted by solar energy. Of course, the solar power generation device 81 of the present invention can also be connected to the solar heating element 82 through an inverter (not shown), so that the inverter can output stable alternating current for use by the vulcanization system.

[0025] When solar energy is directly used to power the vulcanization system, if the solar energy cannot meet the use conditions, such as when there is insufficient sunlight on cloudy or rainy days, or when there is no sunlight at night, the vulcanization system cannot be used normally. Therefore, in order to solve the above technical problems, the capsule air inlet pipeline 40 of the present invention is also provided with an electric heating element 90, and the vulcanization system is powered by the solar heating element 82 combined with the electric heating element 90, thereby solving the problem that the solar energy cannot meet the use conditions, so that the solar energy can be truly used in the vulcanization system.

[0026] The vulcanization system of the present invention further includes a control system C (such as a controller such as MCU, PCL, etc.), and the control system C is electrically connected or electrically connected to the solar heating element 82 and the electric heating element 90, respectively, so as to control the use of the solar heating element 82 and the electric heating element 90 through the control system C. For example, when the solar energy is sufficient, only the solar heating element 82 is used, and when the solar energy is insufficient, the solar heating element 82 and the electric heating element 90 are used at the same time, or only the electric heating element 90 is used. The electrical connection of the present invention refers to a physical electrical connection, and the electrical connection refers to connection through various wireless signals, that is, wireless communication connection.

[0027] Furthermore, the electric heating element 90 and the solar heating element 82 of the present invention are arranged in parallel on the capsule air inlet pipeline 40 .

[0028] In actual use, although the control system can independently control the opening or closing of the electric heating element 90 or the solar heating element 82, that is, to provide electric energy or not. However, since the electric heating element 90 and the solar heating element 82 are arranged in parallel in the vulcanization system, even if the electric heating element 90 or the solar heating element 82 does not provide electric energy, part of the vulcanization medium will be diverted through the electric heating element 90 or the solar heating element 82, and at this time, the electric heating element 90 or the solar heating element 82 plays the role of conducting the pipeline. The following is an example of sufficient electric energy provided by the solar heating element 82. Since part of the vulcanization medium will be heated to a certain temperature through the solar heating element 82, the other part of the vulcanization medium will still maintain a normal temperature through the electric heating element 90 that does not provide electric energy. When these two parts of the vulcanization medium are merged into the capsule, the temperature of the mixed vulcanization medium will be reduced, thereby increasing energy consumption or prolonging the operation time.

[0029] Therefore, in order to solve the above technical problems, preferably, the capsule air inlet pipeline 40 of the present invention includes an electric heating pipeline 41, the electric heating element 90 is arranged on the electric heating pipeline 41, and a first valve element F11 is arranged on the end of the electric heating pipeline 41 away from the capsule air inlet 21. During the vulcanization process, when the electric heating element 90 is needed to heat the vulcanization medium, the first valve element F11 is turned on so that the vulcanization medium can pass through the electric heating element 90 to heat the vulcanization medium. When the electric heating element 90 is not needed to heat the vulcanization medium, the first valve element F11 is closed so that the vulcanization medium does not pass through the electric heating element 90, so as to reduce the energy consumption of the electric heating element 90 due to low temperature.

[0030] Preferably, the capsule air inlet pipeline 40 includes a solar heating pipeline 42, the solar heating element 82 is arranged on the solar heating pipeline 42, and a second valve element F12 is arranged on the end of the solar heating pipeline 42 away from the capsule air inlet 21. During the vulcanization process, when the solar heating element 82 is needed to heat the vulcanization medium, the second valve element F12 is turned on so that the vulcanization medium can pass through the solar heating element 82 to heat the vulcanization medium. When the solar heating element 82 is not needed to heat the vulcanization medium, the second valve element F12 is closed so that the vulcanization medium does not pass through the solar heating element 82, so as to reduce the energy consumption of the solar heating element 82 due to the low temperature.

[0031] The first valve element F11 and the second valve element F12 described in the present invention may be switch valves, so as to control the conduction states of the electric heating pipeline 41 and the solar heating pipeline 42 respectively.

[0032] When both the first valve element F11 and the second valve element F12 are switch valves, if the heat provided by the solar heating element 82 is insufficient to meet the heat required in the vulcanization operation, only the electric heating element 90 can be used for the vulcanization operation, but this case cannot maximize the use of solar energy. At this time, if the solar heating element 82 and the electric heating element 90 are used to heat the vulcanization medium at the same time, part of the vulcanization medium passing through the solar heating element 82 may not be heated enough, that is, the temperature of part of the vulcanization medium passing through the solar heating element 82 may be low, even if the temperature of another part of the vulcanization medium passing through the electric heating element 90 meets the vulcanization conditions, when these two parts of the vulcanization medium are mixed and enter the capsule, they may not meet the vulcanization requirements.

[0033] Therefore, in order to solve the above-mentioned problem that when the solar heating element 82 and the electric heating element 90 are used at the same time, the heat provided by the solar heating element 82 is insufficient, resulting in insufficient heating of part of the vulcanization medium passing through the solar heating element 82, the first valve element F11 and the second valve element F12 described in the present invention can be set as flow valves. When the vulcanization medium is heated by the solar heating element 82 and the electric heating element 90 at the same time, the gas flow rate passing through the first valve element F11 and the second valve element F12 is adjusted, so that part of the vulcanization medium passing through the solar heating element 82 can be heated to the required temperature. When a part of the vulcanization medium passing through the solar heating element 82 and another part of the vulcanization medium passing through the electric heating element 90 are mixed into the capsule, the vulcanization requirements can be met, thereby maximizing the rational use of the solar heating element 82 to heat the vulcanization medium and reducing the power loss at the electric heating element 90. For example, when the solar heating element 82 can provide more heat energy, the gas flow through the second valve element F12 is increased accordingly, and the gas flow through the first valve element F11 is reduced; when the solar heating element 82 can provide relatively less heat, the gas flow through the second valve element F12 is reduced accordingly, and the gas flow through the first valve element F11 is increased, so that the temperature of the inert gas entering the capsule can be controlled by controlling the ratio of the gas flow through the solar heating element in the solar heating unit and the gas flow through the electric heating element. On the other hand, when the first valve element F11 and the second valve element F12 are flow valves, the function of the switch valve can also be realized. For example, when only the solar heating element is used, the opening degree of the second valve element F12 is set to the maximum, that is, 100% open, and the opening degree of the first valve element F11 is set to the minimum, that is, 0; when only the electric heating element 90 is used, the opening degree of the first valve element F11 is set to the maximum, that is, 100% open, and the opening degree of the second valve element F12 is set to the minimum, that is, 0.

[0034] The solar heating element 82 of the present invention is provided with a first temperature measuring element W1 for real-time detection of the external temperature of the solar heating element 82. The control system C can compare the temperature detected by the first temperature measuring element W1 with the target temperature (the target temperature refers to the theoretical external temperature that the solar heating element 82 should reach when the vulcanization requirements are met), thereby determining whether to use the electric heating element 90 or the solar heating element 82. When the first valve element F11 and the second valve element F12 are both flow valves, the control system C can compare the temperature detected by the first temperature measuring element W1 with the target temperature, thereby adjusting the gas flow through the first valve element F11 and the gas flow through the second valve element F12, so that the gas flow through the first valve element F11 can be completely heated by the solar heating element 82 to a temperature that meets the requirements, thereby allowing the vulcanization system to use solar energy to the maximum extent.

[0035] The present invention can also set a second temperature measuring element W2 at the outlet of the solar heating element 82 or on the capsule air inlet pipeline 40 at the outlet of the solar heating element 82 to detect the temperature of the vulcanizing medium at the outlet of the solar heating element 82 in real time. The control system C can compare the temperature detected by the second temperature measuring element W2 with the target temperature (the target temperature refers to the theoretical temperature that the vulcanizing medium at the outlet of the solar heating element 82 should reach when the vulcanization requirements are met) to determine whether to use the electric heating element 90 and the solar heating element 82 for heating. When the first valve element F11 and the second valve element F12 are both flow valves, the control system C can compare the temperature detected by the second temperature measuring element W2 with the target temperature to adjust the gas flow through the first valve element F11 and the gas flow through the second valve element F12, so that the gas flow through the first valve element F11 can be completely heated by the solar heating element 82 to the required temperature, so that the vulcanization system can use solar energy to the maximum extent.

[0036] The capsule air inlet 21 or the capsule air inlet pipeline 40 at the capsule air inlet of the present invention is provided with a third temperature measuring element W3, and the capsule air outlet 22 or the capsule air outlet pipeline 50 at the capsule air outlet is provided with a fourth temperature measuring element W4, so as to detect the vulcanization medium temperature at the capsule air inlet and the vulcanization medium temperature at the capsule air outlet 22 during the vulcanization process in real time. The third temperature measuring element W3 can be used to detect in real time the temperature of the vulcanizing medium at the capsule air inlet or the capsule air outlet, and compare it with the target temperature of the vulcanizing medium (the target temperature of the vulcanizing medium refers to the theoretical temperature that the vulcanizing medium at the capsule air inlet or the capsule air outlet should reach when the vulcanization requirements are met). By adjusting the gas flow rate through the first valve element F11 and the second valve element F12, that is, controlling the flow rate of the vulcanizing medium passing through the electric heating element 90 and the solar heating element 82 respectively, the temperature of the vulcanizing medium at the capsule air inlet or the capsule air outlet detected in real time by the third temperature measuring element W3 is equal to the target temperature of the vulcanizing medium, thereby ensuring that the vulcanization system can use solar energy to the maximum extent when the vulcanization conditions are met.

[0037] The electric heating element 90 of the present invention is provided with a fifth temperature measuring element W5 to detect the external temperature of the electric heating element 90 in real time; a sixth temperature measuring element W6 is provided at the outlet of the electric heating element 90 to detect the temperature of the vulcanizing medium at the outlet of the electric heating element 90 in real time, so as to better feed back the electric energy provided by the electric heating element 90 to the control system C.

[0038] The inflation pipeline 60 of the present invention comprises a low-pressure vulcanization medium inflation pipeline 61 and a high-pressure vulcanization medium inflation pipeline 62 arranged in parallel, the low-pressure vulcanization medium inflation pipeline 61 and the high-pressure vulcanization medium inflation pipeline 62 are respectively connected to an air source (not shown), the low-pressure vulcanization medium inflation pipeline 61 is used to fill the capsule 20 with a low-pressure vulcanization medium, and the high-pressure vulcanization medium inflation pipeline 62 is used to fill the capsule 20 with a high-pressure vulcanization medium. The exhaust pipeline 70 comprises a vulcanization medium recovery pipeline 71, a vacuum pipeline 72 and an emptying pipeline 73 arranged in parallel, the vulcanization medium recovery pipeline 71 is used to recover the vulcanization medium, and the vulcanization medium can be recovered into an air intake source or a separate recovery device (not shown); the emptying pipeline 73 is used to discharge the vulcanization medium that cannot be recovered; the vacuum pipeline 72 is used to form a negative pressure in the vulcanization system, so as to empty the vulcanization medium that may be lower than the standard atmospheric pressure.

[0039] The present invention also discloses a control method for a tire vulcanization system having a solar heating unit for heating an inert gas vulcanization medium, which comprises the following steps: S1: introducing a low-pressure vulcanization medium into a capsule 20 through a low-pressure vulcanization medium inflation pipeline 61 and a capsule air inlet pipeline 40 to shape a green tire; S2: introducing a high-pressure vulcanization medium into a vulcanization system through a high-pressure vulcanization medium inflation pipeline 62 and a capsule air inlet pipeline 40 and heating the high-pressure vulcanization medium so that the high-temperature and high-pressure vulcanization medium enters the capsule 20 to heat the capsule 20; S3: The vulcanizing medium is circulated and vulcanized in a loop formed by a medium circulation device 30, a capsule air inlet line 40, a capsule 20 and a capsule air outlet line 50, which includes S31: a heating method before a stable vulcanization state; and S32: a heating method after a stable vulcanization state; S4: recovering and emptying the vulcanizing medium through an exhaust line 70; wherein, in any step from S1 to S3, the vulcanizing medium is heated by a solar heating unit 80, thereby applying renewable solar energy to the vulcanization process of green tires to reduce traditional energy consumption and carbon emissions.

[0040] In any one or more steps from S1 to S3, the real-time detected temperature of the solar heating element 82 in the solar heating unit 80 or the inert gas vulcanization medium in the vulcanization system is collected in real time, and the real-time detected temperature (a certain device or a certain position is selected for real-time temperature detection) is compared with the target temperature (the target temperature refers to the theoretical temperature that should be reached at the device or the position to meet the corresponding vulcanization requirements in the corresponding step) through the control system C, so as to determine how to turn on the electric heating element 90 and the solar heating element 82 to control the temperature of the vulcanization medium entering the capsule to meet the vulcanization requirements; when the real-time detected temperature is greater than or equal to the target temperature, the solar heating element 82 is turned on, and the electric heating element 90 can be turned on or off as required; when the real-time detected temperature is less than the target temperature, the electric heating element 90 is turned on, and the solar heating element 82 can be turned on or off as required.

[0041] When the first valve element F11 and the second valve element F12 are switch valves, since in steps S2 and S31, it is necessary to quickly transfer heat to the raw tire, preferably, the real-time detected temperature of the vulcanizing medium at the solar heating element 82 or in the vulcanizing system is collected and compared with the target temperature. When the real-time detected temperature is greater than or equal to the target temperature, it means that the solar heating element 82 can provide corresponding thermal energy or electrical energy to meet the corresponding vulcanization requirements, and only the solar heating element 82 is turned on for heating; when the real-time detected temperature is lower than the target temperature, it means that the thermal energy or electrical energy provided by the solar heating element 82 cannot meet the corresponding vulcanization requirements, and only the electric heating element 90 is turned on for heating, thereby achieving heating of the vulcanizing medium to the required temperature in the shortest time.

[0042] When the first valve element F11 and the second valve element F12 are switch valves, in step S32, since the required thermal energy is not much, it is preferred to collect the real-time detected temperature of the solar heating element 82 or the vulcanization medium in the vulcanization system and compare it with the target temperature. When the real-time detected temperature is greater than or equal to the target temperature, it means that the solar heating element 82 can provide corresponding thermal energy or electric energy to meet the corresponding vulcanization requirements, and only the solar heating element 82 is turned on for heating; when the real-time detected temperature is lower than the target temperature, it means that the thermal energy or electric energy provided by the solar heating element 82 cannot meet the corresponding vulcanization requirements, and only the electric heating element 90 is turned on for heating to avoid the solar heating element 82 absorbing heat energy from the vulcanization medium due to too low temperature and increasing energy consumption.

[0043] When the first valve element F11 and the second valve element F12 are flow valves, the solar heating element 82 and the electric heating element 90 can be turned on in any step from S1 to S3, and the temperature at the solar heating element 82 or the temperature of the vulcanizing medium in the vulcanizing system is collected in real time and compared with the target temperature, and the gas flow rate passing through the solar heating element 82 and the gas flow rate passing through the electric heating element 90 are controlled to meet the temperature requirement of the vulcanizing medium during the vulcanization process.

[0044] Preferably, the real-time detected temperature at the solar heating element 82 described in the present invention can be the external temperature TC1 of the solar heating element detected by the first temperature measuring element W1, and the first temperature measuring element W1 is arranged outside the solar heating element 82; when in the S1 step, the target temperature is the first target temperature TA1, and the first target temperature TA1 is the theoretical external temperature that the solar heating element 82 should reach when the vulcanization requirements are met in the S1 step; when in the S2 step, the first target temperature TA1 is the theoretical external temperature that the solar heating element 82 should reach when the vulcanization requirements are met in the S2 step; when in the S31 step, the first target temperature TA1 is the theoretical external temperature that the solar heating element 82 should reach when the vulcanization requirements are met in the S31 step; when in the S32 step, the first target temperature TA1 is the theoretical external temperature that the solar heating element 82 should reach when the vulcanization requirements are met in the S32 step; that is, the first target temperature TA1 of the solar heating element is required to be different in different steps. By using the external temperature TC1 of the solar heating element as the judgment condition for using the solar heating element 82 and the electric heating element 90, it is possible to judge whether the electric heating element needs to be used when the vulcanization medium has not passed through the solar heating element 82, so that when the electric heating element 90 needs to be used, the electric heating element 90 can be turned on in advance; or when the vulcanization medium has not passed through the solar heating element 82, it is possible to judge the gas flow rates passing through the electric heating element 82 and the solar heating element 90 respectively, and set the opening degrees of the first flow valve F11 and the second flow valve F12 in advance to meet the vulcanization requirements more quickly.

[0045] As another embodiment, the real-time detected temperature at the solar heating element 82 of the present invention can be the vulcanization medium temperature TC2 at the outlet of the solar heating element detected by the second temperature measuring element W2, and the target temperature is the second target temperature TA2, that is, the target temperature of the vulcanization medium at the outlet of the solar heating element; when in step S1, the second target temperature TA2 is the theoretical temperature that the vulcanization medium at the outlet of the solar heating element should reach when the vulcanization requirements are met in step S1; when in step S2, the second target temperature TA2 is the theoretical temperature that the vulcanization medium at the outlet of the solar heating element should reach when the vulcanization requirements are met in step S2; when in step S31, the second target temperature TA2 is the theoretical temperature that the vulcanization medium at the outlet of the solar heating element should reach when the vulcanization requirements are met in step S31; when in step S32, the second target temperature TA2 is the theoretical temperature that the vulcanization medium at the outlet of the solar heating element should reach when the vulcanization requirements are met in step S32; that is, the target temperature TA2 of the vulcanization medium at the outlet of the solar heating element is different in different steps. By using the temperature of the vulcanizing medium at the outlet of the solar heating element 82 as a judgment condition for using the solar heating element 82 and the electric heating element 90, or as a judgment condition for the distribution ratio of the gas flow passing through the electric heating element 90 and the solar heating element 82, adjustments can be made based on the actual temperature of the vulcanizing medium as feedback, so that the temperature can be more accurately controlled to meet the vulcanization requirements.

[0046] Optionally, when the temperature of the vulcanizing medium entering the capsule is controlled by controlling the ratio of the gas flow rate passing through the solar heating element 82 and the gas flow rate passing through the electric heating element 90 to meet the vulcanization conditions, the third temperature measuring element or the fourth temperature measuring element W4 provided at the capsule air inlet can be used to collect the vulcanizing medium temperature TC3 at the capsule air inlet or the capsule air outlet 22 in real time and compare it with the target temperature. At this time, the target temperature is the third target temperature TA3, that is, the theoretical target temperature of the vulcanizing medium at the capsule air inlet or the capsule air outlet when the vulcanization requirements are met in the corresponding step, so as to adjust the gas flow rate passing through the solar heating element 82 and the gas flow rate passing through the electric heating element 90 until the vulcanizing medium temperature TC3 at the capsule air inlet or the capsule air outlet is equal to the vulcanizing medium target temperature TA3, so that the flow rate of the vulcanizing medium passing through the solar heating element 82 can be reasonably utilized, thereby maximizing the use of solar energy and meeting the vulcanization requirements more quickly.

[0047] The method of adjusting the ratio of the gas flow passing through the solar heating element 82 and the gas flow passing through the electric heating element 90 described in the present invention may be to open the second flow valve F12 provided on the solar heating pipeline 42 to the maximum flow state, and gradually increase the flow opening degree of the first flow valve F11 on the electric heating pipeline 41, so that the real-time detected temperature is consistent with the target temperature; or the first flow valve F11 provided on the second electric heating pipeline 41 may be opened to the maximum flow state, and gradually increase the flow opening degree of the second flow valve F12 on the solar heating pipeline 42, so that the real-time detected temperature is consistent with the target temperature; or when the heat energy that the solar heating element 82 can provide is within a certain range, the gas flow passing through the solar heating element 82 and the gas flow of the electric heating element 90 are a certain fixed ratio, and when the heat energy that the solar heating element 82 can provide is within another range, the gas flow passing through the solar heating element 82 and the gas flow of the electric heating element 90 are another fixed ratio.

[0048] It can be known from the above disclosed technical contents that the tire vulcanization system provided by the present invention having a solar heating unit for heating an inert gas vulcanization medium mainly realizes the purpose of reducing energy consumption by providing a solar heating unit 80 for heating the tire vulcanization system, thereby applying solar energy to the vulcanization system; and by providing an electric heating element 90 in the vulcanization system to cooperate with the solar heating element 82 in the solar heating unit to provide thermal energy for the vulcanization system, even when the thermal energy provided by the solar heating element 82 is insufficient to meet the vulcanization requirements, the vulcanization system can be ensured to operate normally; in different steps of the vulcanization of the raw tire, the control system C determines whether to turn on the solar heating element 82 or the electric heating element 90 according to different external conditions, or by controlling the gas flow rate passing through the solar heating element 82 and the gas flow rate ratio of the electric heating element 90, thereby using solar energy to the maximum extent while ensuring that the vulcanization conditions are met, thereby reducing energy consumption.
