Description

Technical Field

[0001] The invention relates to the field of tire vulcanization, and in particular to an electric heating vulcanization device. Background Art

[0002] Electric heating tire vulcanization equipment needs to circulate high-pressure gas (usually nitrogen) and heat it through a heating device, and the gas circulation pump is the core component. The centrifugal circulation pumps and Roots pumps currently used have the problem of short service life. The factor causing this problem is that the high-temperature gas after heating during tire vulcanization will pass through the location of the pump, causing the dynamic seal of the pump to fail, thereby reducing the service life of the drive motor; based on the above problems, the prior art has designed a vulcanization equipment in which the pump is arranged on the outside of the central mechanism. Although this design avoids the entire pump being in the high-temperature gas during tire vulcanization, the high-temperature circulating gas in the pipeline will transfer heat to the motor through gaps or heat transfer, which will still shorten the service life of the motor.

Beneficial effects:

[0013] 1. The present invention provides an electric heating vulcanization equipment in which the driving device of the axial flow fan is arranged at the lower end of the outer side of the entire pipeline in the heating circulation pipeline. When the gas in the inlet pipe and the outlet pipe circulates, the high-temperature gas is accelerated to move upward under the thrust of the axial flow fan, and the driving device is arranged at the lower end of the outer side of the pipeline in the upwind direction of the high-temperature gas and away from the high-temperature gas environment. At the same time, an isolation cover is arranged between the rotating shaft inside the axial flow fan and the driving device. This design method effectively reduces the temperature of the driving device and extends the service life of the driving device.

[0014] 2. In order to prevent the leakage of high-temperature gas and further reduce the heating of the drive device, the present invention provides a sealing ring between the isolation cover and the first bearing fixing seat cover. This design cuts off the path for the high-temperature gas to leak into the drive device, thereby further reducing the heating degree of the drive device and extending the service life of the drive device.

[0015] 3. In order to prevent high-temperature gas from leaking from the inside, the present invention provides a labyrinth seal on one end of the rotating shaft close to the inlet and outlet pipes to prevent leakage of high-temperature gas.

[0016] 4. Another measure taken by the present invention is to set an insulation layer between the main casing and the driving device to reduce the heat transferred from the high-temperature gas in the axial flow fan pipeline to the driving device through the pipeline. This method blocks the heating of the driving device in the heat transfer path, further reduces the high-temperature heating of the driving device, and extends the service life of the driving device.

[0017] 5. In order to ensure that the bearing fixing seat can be fixed, the present invention arranges the bearing fixing seat in its corresponding pressure cover, and the pressure cover is provided with a protrusion that cooperates with the bearing fixing seat to prevent the bearing fixing seat from moving in the axial direction.

The specific process is as follows: the axial flow fan drive device drives the inner magnetic rotor through the outer magnetic rotor, thereby driving the shaft in the outer shell of the axial flow fan body to rotate and then driving the blades to rotate. The rotation of the blades generates thrust to push the heated high-temperature nitrogen along the air intake pipe into the capsule, and then from the capsule through the exhaust pipe, the axial flow fan and the heater to the capsule for circulation, thereby vulcanizing the tire; after vulcanization is completed, the exhaust control valve is opened, at which time the air intake control valve is in a closed state, the exhaust control valve is in an open state, and the high-temperature gas in the capsule is discharged through the exhaust control valve.
