[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0033] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0034] like Figure 1 As shown, the present invention provides a thermal cycle system for electromagnetically heating a gas medium, comprising:

[0035] A gas recovery unit, used to recover the gas discharged from the main body of the equipment;

[0036] A heating device 5, used for heating the recovered gas;

[0037] The gas circulation unit is used to make the recovered gas pass through the heating device 5 and provide the gas heated to the first target temperature to the device body for heating.

[0038] The equipment body is a device that requires heat circulation gas. The gas recovery unit can recover the gas discharged from the equipment body, and then heat the gas by electric heating through the heating device 5. The gas circulation unit is used to realize the heat circulation of the gas, and the gas at the first target temperature is provided to the equipment body to provide a heat source for the equipment body. When in use, the temperature, pressure, flow rate and other parameters of the equipment body can be controlled online in real time according to the combination with the intelligent temperature control system.

[0039] When the present invention is applied in the vulcanization molding production process of rubber tires, carbon dioxide gas is selected for circulating heating. Carbon dioxide is the best gas medium for heat transfer and can be repeatedly recycled. The heating device 5 does not need water to heat carbon dioxide, nor does it consume energy such as coal and natural gas. There is no harmful gas emission, which is more energy-saving and environmentally friendly.

[0040] When the present invention is applied in a heating project, air is selected for circulating heating. Similarly, the heating device 5 does not need water to heat the air, and does not need to consume energy such as coal and natural gas.

[0041] In the above scheme, the heating device 5 heats the gas medium by electric heating, the gas circulation unit provides power for the gas circulation, and the gas discharged from the equipment body can be recovered through the gas recovery unit to fully utilize the heat of the circulating gas and reduce the energy consumption of the heating device 5; and in the entire circulation system, there is no need to consume energy such as water, coal and natural gas, no harmful gas emissions, energy saving, and more environmentally friendly.

[0042] Furthermore, the heating device 5 adopts an electromagnetic heating body.

[0043] The electromagnetic heating body can quickly heat the passing gas to achieve gas thermal circulation.

[0044] like Figure 1 As shown, in one embodiment, the gas recovery part includes: a plurality of first recovery gas storage tanks 1, the gas inlet end of the first recovery gas storage tank 1 is connected in sequence with a first valve 2 and a plurality of first interfaces A through a pipeline, the first interface A is used to connect to the first exhaust port of the equipment body, and the gas outlet end of the first recovery gas storage tank 1 is connected to the gas circulation part through a pipeline.

[0045] Among them, the number of first recovery gas storage tanks 1 is set according to actual needs.

[0046] The plurality of first interfaces A are used to connect to the first exhaust port of the device body. The number of the first interfaces A corresponds to the number of the device body. After the device body discharges the gas, the gas is transported to the plurality of first recovery gas storage tanks 1 through the first valve 2 for storage. The plurality of first recovery gas storage tanks 1 can increase the amount of recovered gas, and then the gas in the first recovery gas storage tanks 1 is transported to the gas circulation part.

[0047] The first exhaust port of the equipment body is used to discharge high-temperature gas. Therefore, when the equipment body needs to circulate high-temperature gas, the gas is introduced into the first recovery gas storage tank 1 through the first exhaust port, and then passes through the gas circulation part and the heating device 5 to realize the circulation of high-temperature gas in the equipment body.

[0048] Furthermore, the gas circulation part includes: multiple first circulation gas tanks 3 and multiple first circulation devices 4, the air inlet end of each first circulation gas tank 3 is connected to the heating device 5 and the first circulation device 4 in sequence through a pipeline, the air outlet ends of the multiple first circulation gas tanks 3 are connected to the second valve 6 through a pipeline, the second valve 6 is connected to multiple second interfaces B through a pipeline, the second interface B is used to be connected to the first air inlet of the equipment body, and the first circulation device 4 is connected to the gas recovery part through a pipeline.

[0049] The number of the first circulation gas storage tank 3, the first circulation device 4 and the heating device 5 is set according to actual needs.

[0050] The gas discharged from the first recovery gas storage tank 1 is transported to the heating device 5 for heating through the first circulation device 4. The heating device 5 can heat the gas to a required temperature and then transport it to the first circulation gas storage tank 3. Multiple first circulation gas storage tanks 3 are used to store the heated high-temperature gas so as to provide high-temperature gas to multiple equipment bodies at the same time. Each first circulation gas storage tank 3 corresponds to a heating device 5 and a first circulation device 4. The high-temperature gas in the first circulation gas storage tank 3 is transported and distributed to multiple second interfaces B through the second valve 6, so as to provide the equipment body with gas that meets the first target temperature through the first air inlet. The number of second interfaces B is also set corresponding to the number of equipment bodies to provide hot circulation gas to multiple equipment bodies at the same time.

[0051] In one embodiment, the gas recovery unit also includes: a plurality of second circulating gas storage tanks 7, the gas inlet end of the second circulating gas storage tank 7 is sequentially connected to a third valve 8 and a plurality of vacuum interfaces C through a pipeline, and the vacuum interface C is used to be connected to the vacuum exhaust port of the equipment body; the gas outlet end of the second circulating gas storage tank 7 is sequentially connected to a vacuum pump 9 and a one-way valve 10 through a pipeline, and the one-way valve 10 is connected to the gas inlet end of the first recovery gas storage tank 1 through a pipeline.

[0052] The number of the second circulation gas storage tank 7 and the vacuum tank 9 is set according to actual needs.

[0053] During the vulcanization and molding production process of rubber tires, the equipment body first heats and vulcanizes the rubber tires with high-temperature gas, and then shapes them with low-temperature gas. After shaping is completed, the equipment body needs to be evacuated to recover the carbon dioxide; therefore, multiple second circulation gas storage tanks 7 and vacuum pumps 9 are set, and multiple vacuum interfaces C are connected to the vacuum exhaust port of the equipment body. After shaping is completed, the third valve 8 is opened, and the vacuum pump 9 provides power to first suck the gas in the equipment body into the second circulation gas storage tank 7, and then the vacuum pump 9 allows the gas to be recovered to the first recovery gas storage tank 1 through the one-way valve 10, which can realize repeated circulation heating and vulcanization and prevent residual carbon dioxide gas in the equipment body.

[0054] like Figure 2 As shown, in one embodiment, it also includes: a low-temperature gas recovery circulation unit for recovering and cooling the gas exhausted from the equipment body, and then providing the gas cooled to the second target temperature to the equipment body.

[0055] In the vulcanization and molding production process of rubber tires, after the equipment body heats and vulcanizes the rubber tire with high-temperature gas, it also needs to be shaped. The gas required for shaping is low-temperature gas. Therefore, after vulcanization, a low-temperature gas recovery circulation unit is used to provide the equipment body with gas at a second target temperature to achieve cooling and shaping of the rubber tire.

[0056] Furthermore, the low-temperature gas recovery circulation unit includes: a fourth valve 11, a third circulation gas storage tank 12, a second circulation device 13, a second recovery gas storage tank 14, a cooling device 15 and a fifth valve 16 connected in sequence through pipelines, the fourth valve 11 is connected to multiple third interfaces D through pipelines, the third interface D is used to be connected to the second air inlet of the equipment body, the fifth valve 16 is connected to multiple fourth interfaces E through pipelines, and the fourth interface E is used to be connected to the second exhaust port of the equipment body.

[0057] The number of the third circulating gas storage tank 12, the second circulating device 13, the second recovery gas storage tank 14 and the cooling device 15 is set according to actual needs.

[0058] During shaping, the fourth valve 11 and the fifth valve 16 are opened, and the circulation power is provided by the second circulation device 13. The low-temperature gas in the third circulation gas storage tank 12 is transported to the plurality of third interfaces D through the fourth valve 11, so that the low-temperature gas enters from the second air inlet of the equipment body, and provides a low-temperature environment for cooling and shaping the rubber wheel. Then, the gas circulated in the equipment body is discharged from the second exhaust port, enters through the fourth interface E, enters the cooling device 15 after passing through the fifth valve 16 for cooling, and then is recovered into the second recovery gas storage tank 14, so as to provide low-temperature gas circulation for the equipment body; the cooling device 15 adopts a pipeline cooler.

[0059] like Figure 3 As shown, in one embodiment, it also includes: a control unit, which is used to control the heating device 5 and the gas circulation unit according to the gas flow rate and the first target temperature provided by the gas circulation unit required by the equipment body;

[0060] The control unit includes:

[0061] A first determination module is used to determine the number of operations of the first circulation device 4 according to the required gas flow rate;

[0062] A second determination module, used to determine the operating temperature of the heating device 5 according to the required first target temperature and the initial temperature of the gas at the air inlet end of the heating device 5;

[0063] The operation control module is used to control the operation of the plurality of first circulation devices 4 and the heating device 5 according to the operation quantity of the first circulation device 4 and the operation temperature of the heating device 5 .

[0064] The gas flow rate provided by the gas circulation unit to the device body refers to the total gas flow rate required by the plurality of device bodies, and the first target temperature refers to the temperature of the gas discharged from the second interface B.

[0065] Since the number of working equipment bodies is uncertain, the gas flow rates required for different numbers of equipment bodies are also different. In addition, in the initial state, the equipment body is in the heating stage, and it requires a larger gas flow rate to quickly heat up. When the temperature is relatively stable, the gas flow rate required to circulate the equipment body is relatively low, and it is sufficient to maintain the working temperature of the equipment body. The control of the gas flow rate mainly depends on the number of operations of the first circulation device 4. The larger the number, the larger the gas flow rate provided by the gas circulation part, and the smaller the number, the smaller the gas flow rate provided by the corresponding gas circulation part. Therefore, at the beginning, the required gas flow rate can be determined according to the number of equipment bodies, thereby determining the number of operations of the first circulation device 4. At the beginning of work, dynamic control can be performed to reduce operating energy consumption.

[0066] The heating device 5 is used to heat and increase the temperature of the gas. Related to its work are the first target temperature and the initial temperature of the gas at the air inlet end of the heating device 5. The initial temperature is the temperature of the recovered gas, which changes dynamically. When the heating device 5 is in operation, it can meet the needs of heating the gas at the initial temperature so that the gas circulation unit can provide the equipment body with gas at the first target temperature. Therefore, the operating temperature of the heating device 5 can be determined by the second determination module to achieve control of the heating device 5.

[0067] In one embodiment, it further includes:

[0068] The dynamic operation adjustment module is used to optimize the operating energy consumption of the gas circulation unit and the heating device 5 according to the inlet temperature and outlet temperature of the equipment body.

[0069] Since the main body of the equipment is in the heating stage at the beginning of operation, the difference between the inlet temperature and the outlet temperature is large, so the required operating energy consumption is relatively large. When the temperature inside the main body of the equipment is relatively stable, the difference between the inlet temperature and the outlet temperature is small. At this time, it is necessary to optimize the number of heating devices 5 and the first circulation device 4 to reduce operating energy consumption and further achieve the purpose of energy saving.

[0070] like Figure 4 As shown, further, the operation dynamic adjustment module includes:

[0071] An acquisition unit, used to acquire a temperature difference between an inlet temperature and an outlet temperature of a device body, and to obtain a set level to which the temperature difference belongs;

[0072] The adjustment unit controls the first circulation device 4 and the heating device 5 to operate at corresponding quantities according to the set level to which the temperature difference belongs, while maintaining the gas provided to the equipment body at the first target temperature.

[0073] The setting levels include: the first level and the second level, the first level corresponds to the first temperature difference range, the second level corresponds to the second temperature difference range, and the temperature difference corresponding to the second level is greater than the temperature difference corresponding to the first level;

[0074] The first level indicates that the temperature difference is very small (approaching zero), and the working temperature of the equipment body enters a stable period. The second level indicates that the temperature difference is large, and the working temperature of the equipment body is in a rising period.

[0075] When the setting level to which the temperature difference belongs is the first level, the first circulation device 4 and the heating device 5 enter the energy-saving mode, that is, the first circulation device 4 operates at the minimum number to meet the gas circulation demand of the main body of the equipment, and the ratio A of the operating number of the heating device 5 to the operating number of the first circulation device 4 satisfies: 1 / 2≤A<1;

[0076] In the energy-saving mode, since the gas provided to the device body needs to be kept at the first target temperature, the heating temperature of the heating device 5 actually changes dynamically, and when the number of operating heating devices 5 is less than the number of operating first circulation devices 4, the gas passing through at least one of the first circulation devices 4 is transported to the device body without heating, so in order to ensure that the gas temperature provided by the gas circulation unit is maintained at the first target temperature, it is necessary to appropriately increase the heating temperature of the heating device 5. Therefore, it is necessary to consider whether the temperature stability in the device body can be guaranteed when operating in the energy-saving mode. If not, when the first circulation device 4 is operated at the minimum number to meet the gas circulation demand of the device body, the operating number of the heating device 5 is set to be the same as the operating number of the first circulation device 4. If so, continue to operate in the energy-saving mode;

[0077] To determine whether the temperature stability in the main body of the device is guaranteed in energy-saving mode, the following formula is used:

[0078]

[0079] Wherein, τ is the flow parameter corresponding to the pipeline where the heating device 5 is not running and the first circulation device 4 is running, T1(n+1) and T1(n) are the actual temperatures in the equipment body obtained for the n+1th and nth times, respectively, P1(n+1) and P1(n) are the total operating energy consumption of multiple heating devices 5 obtained for the n+1th and nth times, respectively, T2(n+1) and T2(n) are the temperature differences between the actual temperature in the equipment body obtained for the n+1th and nth times and the set temperature, respectively, t(n+1) and t(n) are the acquisition times for the n+1th and nth times, respectively, K1, K2, and K3 are coefficients related to the actual temperature in the equipment body, the total operating energy consumption of multiple heating devices 5, and the temperature difference between the actual temperature in the equipment body and the set temperature, respectively. Specifically, K1, K2, and K3 can be established with the actual temperature T1 in the equipment body, the total operating energy consumption P1 of multiple heating devices 5, and the temperature difference T2 between the actual temperature in the equipment body and the set temperature through the known flow parameter τ, and can be obtained by solving;

[0080] The flow parameter τ has a unique corresponding relationship with the flow rate (flow rate of unheated gas) corresponding to the pipeline where the heating device 5 is not running and the first circulation device 4 is running, so the required flow rate of unheated gas can be known through the obtained flow parameter τ. If the calculated flow rate of unheated gas is less than the current flow rate of unheated gas, it indicates that the stability of the temperature in the main body of the equipment cannot be guaranteed in the energy-saving mode. If the calculated flow rate of unheated gas is greater than or equal to the current flow rate of unheated gas, it indicates that the stability of the temperature in the main body of the equipment can be guaranteed in the energy-saving mode.

[0081] When the setting level of the temperature difference is the second level, it is determined whether the gas flow required by the equipment body needs to be adjusted according to the size of the temperature difference;

[0082] When the gas flow required by the device body needs to be adjusted, the positive and negative values ​​of the flow difference between the adjusted gas flow and the current gas flow are obtained;

[0083] If it is positive, the opening of the second valve 6 is adjusted according to the flow difference, or the number of operations of the first circulation device 4 is increased; wherein the priority of adjusting the opening of the second valve 6 is higher than the priority of increasing the number of operations of the first circulation device 4;

[0084] Since the working temperature of the equipment body is in the rising period at this time, when the temperature difference is large, it is necessary to speed up the gas circulation to increase the temperature rise rate of the equipment body. At this time, the opening of the second valve 6 is adjusted first to increase the gas flow rate, which can reduce the operating energy consumption. If the opening of the second valve 6 is the maximum, the number of operations of the first circulation device 4 is increased, and the number of operations of the heating device 5 is increased at the same time to increase the temperature rise rate of the equipment body;

[0085] If it is negative, the operation quantity of the first circulation device 4 is reduced according to the flow difference, or the opening degree of the second valve 6 is adjusted; wherein, the priority of reducing the operation quantity of the first circulation device 4 is higher than the priority of adjusting the opening degree of the second valve 6;

[0086] When the working temperature of the equipment body transitions from the rising period to the stable period, the temperature difference is small (a set temperature difference can be set. When the temperature difference is less than the set temperature difference), but it has not reached the first level, the gas flow rate can be reduced to reduce the operating energy consumption. That is, when the flow difference is negative, the operating quantity of the first circulation device 4 is reduced first. Of course, if the flow difference is not satisfied to reduce the operating quantity of the first circulation device 4, the opening of the second valve 6 can be adjusted at this time.
