[0046] In the specific embodiment: see Figure 1 The tire 7 is shaped and vulcanized under a mold 6 provided outside and a capsule 8 provided inside. The pressure and heat required for the tire 7 shaping and vulcanization are provided by the vulcanization medium in the capsule 8. The electric vulcanization system uses water 9 as the vulcanization medium, and the water 9 is transported into the capsule 8. The water 9 is heated by an electric water heater 15 provided in the capsule 8.

[0047] In this example: See Figure 2 The electric water heating system 1 includes a filling body 12, which is arranged in the inner cavity of the capsule 8 and fills the area between the upper chuck 10 and the lower chuck 11 connected to the capsule 8. A pressure sensor 13 and a temperature sensor 14 are arranged at the bottom of the filling body 12, and an electric water heater 15 is arranged on the outside of the filling body 12, and the electric water heater 15 is in contact with the water 9 in the capsule 8.

The electric water heater 15 heats the water 9 in the capsule 8. The electric water heater 15 can specifically be a resistive electric water heater 15, and its power is controlled by controlling the current or voltage of the electric water heater 15.

[0049] In this example: See Figure 3 The water inlet and outlet system 2 includes a first filter 16, one end of the first filter 16 is connected to the inner cavity of the capsule 8 through a pipeline, the other end of the first filter 16 is connected to one end of the QD1 shut-off valve 18, one end of the regulating valve 19, and the vacuum system 4, the other end of the QD1 shut-off valve 18 is connected to the other end of the regulating valve 19, one end of the safety valve 20, and one end of the water storage tank 21, the water storage tank 21 is provided with an electric heater 22, the other end of the water storage tank 21 is connected to one end of the ball valve 26 and the water circulation system 5, the other end of the ball valve 26 is connected to one end of the QD2 shut-off valve 27, the other end of the QD2 shut-off valve 27 is connected to one end of the check valve 28, and the other end of the check valve 28 introduces power water 9.

[0050] The power water 9 enters the water storage tank 21 through the check valve 28 and the QD2 shut-off valve 27, and the water 9 is preheated by the electric heater 22. The generated steam is transported to the air intake and exhaust system 3 through the vacuum system 4, and the generated preheated water 9 is transported to the capsule 8 through the QD1 shut-off valve 18 and the regulating valve 19. After a vulcanization cycle, the water 9 in the capsule 8 returns to the water storage tank 21 through the first filter 16 and the QD1 shut-off valve 18 for the next vulcanization cycle. The recycling can save water 9 resources and energy. The regulating valve 19 is connected in parallel with the QD1 shut-off valve 18 to adjust the speed of the capsule 8 water inlet 9 and thus control the water filling pressure of the capsule 8. The water storage tank 21 is also provided with a liquid level sensor 23 for detecting the water volume, a thermocouple 24 for detecting the temperature of the preheated water 9, a pressure transmitter 25 for water pressure detection, and a ball valve 26 for manual drainage. There are at least two safety valves 20, one connected to the capsule 8 and the other connected to the water storage tank 21, to ensure the safety of the two pressure spaces separated by the regulating valve 19 and the QD1 shut-off valve 18 (the other is in the air intake and exhaust system 3).

[0051] In this example: See Figure 4 The air intake and exhaust system 3 includes a second filter 17, one end of the second filter 17 is connected to the inner cavity of the capsule 8 through a pipeline, the other end of the second filter 17 is connected to one end of the cut-off valve and one end of the three-way cut-off valve 30, the other end of the three-way cut-off valve 30 is connected to one end of the balancing valve 31, the other end of the balancing valve 31 is connected to the other end of the cut-off valve and one end of the steam storage tank 32, the other end of the steam storage tank 32 is connected to one end of the QD4 cut-off valve 33, the other end of the QD4 cut-off valve 33 is connected to the outside through a pipeline, and the steam storage tank 32 is also provided with a liquid level sensor 23, a thermocouple 24, and a pressure transmitter 25.

[0052] One end of the air intake and exhaust system 3 is connected to the capsule 8 cavity, and the other end is connected to the drain pipe leading to the outside. The steam in the steam tank 32 is transported into the capsule 8 through the balancing valve 31 and the three-way shut-off valve 30. The steam in the capsule 8 is recovered to the steam tank 32 through the QD3 shut-off valve 29 for the next vulcanization cycle. The recycling of steam can save water 9 resources and energy. During system maintenance, the pressure in the steam tank 32 can be automatically discharged through the QD4 shut-off valve 33. The steam tank 32 is also provided with a liquid level sensor 23 for detecting the amount of condensed water, a thermocouple 24 for detecting steam temperature, a pressure transmitter 25 for detecting steam pressure, and a ball valve 26 for manual drainage (the same as the water tank 21). The air intake and exhaust system 3 is also provided with a safety valve 20, which has the same function as the safety valve 20 in the air intake and exhaust system 2 and is arranged at Figure 4 Balance valve 31 lower right.

[0053] In this example: See Figure 5The vacuum system 4 includes a power pump 35, one end of the power pump 35 is connected to one end of QD5 shut-off valve 34 and one end of QD7 shut-off valve 37, the other end of QD5 shut-off valve 34 is connected to the water intake and drainage system 2, the other end of QD7 shut-off valve 37 is connected to the air intake and exhaust system 3, the other end of the power pump 35 is connected to one end of QD6 shut-off valve 36 and one end of QD8 shut-off valve 38, the other end of QD6 shut-off valve 36 is connected to the water intake and drainage system 2, and the other end of QD8 shut-off valve 38 is connected to the air intake and exhaust system 3.

[0054] When the power pump 35 evacuates the capsule 8 through the pipeline, the water 9 returns to the water storage tank 21 and the steam returns to the steam storage tank 32 .

[0055] In this example: See Figure 6 The water circulation system 5 includes a water pump 39 , one end of the water pump 39 is connected to the drainage system 2 , and the other end of the water pump 39 is connected to the exhaust system 3 .

[0056] The water pump 39 transports the condensed water 9 in the steam storage tank 32 to the water storage tank 21 .

[0057] See also Figures 1 to 6 In addition, the various valves mentioned in this application can be appropriately added to the pipeline during actual use based on factors such as safety of use or ease of control.

[0058] A method for using an electric vulcanization system is applied to a tire vulcanizer and can be used for vulcanizing a single-mode tire 7 or a double-mode or multi-mode tire 7, comprising the following steps:

[0059] Step 1: steam is delivered to the capsule 8, and the tire 7 is fixed in the mold 6 by the expansion of the capsule 8, and the gas between the capsule 8 and the tire 7 is discharged. When the mold 6 is closed to compress the green tire from the outside, the expanded capsule 8 supports the green tire from the inside, so that the green tire leads the inner cavity of the mold 6 to deform and the air between the green tire and the mold 6 is discharged;

[0060] Step 2, when the mold 6 is closed to compress the green tire from the outside, the steam in the capsule 8 that exceeds the pressure required for shaping is discharged into the air intake and exhaust system 3;

[0061] Step 3, water 9 is transported into the cavity of capsule 8, and excess steam in capsule 8 is discharged into air intake and exhaust system 3;

[0062] Step 4, heating the water 9 so that the water 9 in the capsule 8 quickly reaches the temperature and pressure required for vulcanization;

[0063] Step 5, keeping the water 9 in the capsule 8 at the temperature and pressure required for vulcanization;

[0064] Step 6, after the tire 7 is vulcanized, the water 9 and steam in the capsule 8 are discharged into the water inlet and outlet system 2 and the air inlet and outlet system 3 respectively;

[0065] Step 7, the remaining water 9 in the main row of the capsule 8 is discharged into the water inlet and outlet system 2, and the remaining steam in the main row is discharged into the air inlet and outlet system 3, so that the capsule 8 is vacuumized and shrunk;

[0066] Step 8, the condensed water 9 in the intake and exhaust system 3 is transported to the intake and exhaust system 2, so that the water 9 is recycled in multiple vulcanization cycles.

[0067] In this example, see Figures 1 to 6 , the specific implementation method is:

[0068] Step 1, shaping steam feed (primary shaping): the electric heater 22 preheats the water 9 in the water storage tank 21, and the generated steam is transported to the steam storage tank 32 through the QD6 cut-off valve 36 and the QD8 cut-off valve 38. The steam in the steam storage tank 32 is transported to the capsule 8 through the balance valve 31, the three-way cut-off valve 30, and the second filter 17 (other valves are also provided in the attached drawings, which are not described in detail here). The tire 7 is fixed in the mold 6 by the expansion of the capsule 8 and the gas between the capsule 8 and the tire 7 is discharged. When the mold 6 is closed to compress the green tire from the outside, the expanded capsule 8 supports the green tire from the inside, so that the green tire leads the inner cavity of the mold 6 to deform and the air between the green tire and the mold 6 is discharged;

[0069] Step 2, shaping and releasing steam (secondary shaping): when the mold 6 is closed to compress the green tire from the outside, the steam in the bladder 8 that exceeds the pressure required for shaping is discharged back to the steam storage tank 32 through the QD3 cut-off valve 29;

[0070] Step 3, power water inlet: the water 9 in the water storage tank 21 is transported to the capsule 8 cavity through the regulating valve 19 and the first filter 16 (other valves are also provided in the figure, which will not be described in detail here), and the excess steam in the capsule 8 returns to the steam storage tank 32 through the QD3 cut-off valve 29;

[0071] Step 4, water electric heating: the electric water heater 15 provided on the electric water heating system 1 heats the water 9 so that the water 9 in the capsule 8 quickly reaches the temperature and pressure required for vulcanization;

[0072] Step 5, water temperature and pressure maintenance: the pressure sensor 13 and temperature sensor 14 provided on the electric water heating system 1 control the power and on / off of the electric water heater 15, so that the water 9 in the capsule 8 maintains the temperature and pressure required for vulcanization;

[0073] Step 6, main discharge: after the tire 7 is vulcanized, the water 9 in the capsule 8 quickly returns to the water storage tank 21 through the QD1 cut-off valve 18, and the steam in the capsule 8 quickly returns to the steam storage tank 32 through the QD3 cut-off valve 29;

[0074] Step 7, vacuuming: the remaining water 9 in the main row of the capsule 8 is transported to the water storage tank 21 through the QD5 cut-off valve 34, the power pump 35, and the QD6 cut-off valve 36, and the remaining steam in the main row is transported to the steam storage tank 32 through the QD7 cut-off valve 37, the power pump 35, and the QD8 cut-off valve 38, so that the capsule 8 is vacuumed and shrunk;

[0075] Step 8, water circulation: the condensed water 9 in the steam storage tank 32 is transported to the water storage tank 21 through the water pump 39, so that the water 9 is recycled in multiple vulcanization cycles, reducing the system water 9 loss and saving water 9 resources and energy.

[0076] See also Figure 7 , which is a time-temperature diagram within a vulcanization cycle, corresponding to steps 1 to 8.

[0077] In the prior art, the medium of the mold 6 heating system and the capsule 8 heating and pressurizing system of the tire vulcanizer is steam, which is transported and controlled by thermal pipelines, which are connected to the thermal main pipe, and the thermal main pipe is connected to the boiler plant. The thermal pipeline, thermal main pipe, and boiler plant are expensive and difficult to maintain, and the heat loss is large during steam transportation. The boiler mainly uses coal and natural gas as fuel, which has an impact on the environment.

[0078] The present invention reduces heat loss during steam transportation, thus saving energy; and uses clean energy electric heating instead of steam heating, thus reducing environmental pollution.

[0079] In the prior art, the green tire shaping vulcanization medium steam of the tire vulcanizer becomes condensed water 9 after use, and the condensed water 9 affects the uniformity of heating. The discharged condensed water 9 contains nearly 30% of heat, which causes energy waste and also water resource waste.

[0080] This application recycles water resources, reduces loss, and saves water resources.

[0081] In the prior art, steam condensed water 9 of the tire vulcanizer accumulates on the lower side of the bladder 8, causing uneven temperatures on the upper and lower sidewalls of the tire 7 and affecting the vulcanization quality.

[0082] When the tire 7 of the present application is vulcanized, the capsule is filled with water, and after the water is electrically heated, the water temperature is balanced so that the capsule 8 and the inner side of the tire 7 are heated evenly, and the vulcanization quality of the tire 7 is good.

[0083] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0084] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
