A tire curing device

Abstract

The invention relates to the technical field of tire vulcanization, and discloses a tire vulcanization device, which includes a vulcanization tank, a heating assembly and a waste heat recovery assembly. The vulcanization tank is provided with a storage chamber, and a storage rack is provided in the storage chamber. A tank is provided on the top of the vulcanization tank. The cover, the heating assembly is hooped on the outer wall of the autoclave, and the heating assembly includes a heating element, a conveying element and a heating element, and the waste heat recovery assembly cooperates with the tank cover and the heating element respectively. The advantage of the present invention is that the liquid in the steam water tank is heated by the heating furnace and the liquid is vaporized, and then the high-temperature steam enters the vulcanization tank through the steam delivery pipe through the winding delivery pipeline, so that the temperature in the vulcanization tank is uniformly increased At the same time, it is also possible to pressurize the vulcanization tank. The guide air duct is set so that the high-temperature steam entering the vulcanization tank can be evenly distributed in the vulcanization tank, so that the temperature in the vulcanization tank is consistent, so as to avoid the temperature difference in the vulcanization tank and cause tire vulcanization. Quality has deviated.

Problems solved by technology

[0002] Most of the current vulcanizers are heated by a steamer. The way of heating vulcanization is to place the entire tire curing mold in a steamer with steam for vulcanization. After the vulcanization is complete, all the steam in the steamer should be released. The main disadvantages of this form of vulcanization heating are slow heating, uneven temperature, and waste of energy. In view of this situation, in order to improve the utilization rate of heat energy, more than half of the external temperature heating of vulcanizers now uses hot plate heating instead of steamer heating. , but there are two main structures: one is that the heating plate is fixed on the vulcanizing machine, and the other is that it is made together with the vulcanizing mold.

Although some shortcomings of the steamer are solved or improved, such as changing the heating form and improving some vulcanization heat efficiency, the two structures also have different problems, for example: 1. The hot plate is fixed on the vulcanizer, which facilitates mold repair and Cleaning and other problems, but the heating accuracy is poor, the heating of the inner ring or outer ring is still wasted, the thermal conductivity of the hot plate to the mold is low, the energy saving effect is not obvious, and there are also phenomena of slow heating and uneven temperature

2. When the hot plate and the vulcanization mold are combined, the heating accuracy is improved, the heat conduction coefficient of the hot plate to the mold is improved, the temperature rise is accelerated, and the heating temperature is relatively uniform, but the repair and cleaning of the mold are more difficult, maintenance and Strong cleaning intensity, especially in the disassembly and assembly of molds and the cleaning of air holes

[0004] Although the above-mentioned device can carry tires, it also has the following problems when tires are vulcanized: the first, when tires are vulcanized, only infrared heating plates are used to heat the tires on the rack, and the temperature rise rate is relatively slow, and it is not heated by infrared heating. The place covered by the heating plate cannot be heated, which may easily cause the difference in temperature difference in the heating barrel to affect the tire vulcanization; second, after the tire is vulcanized, it needs to be cooled due to the high surface temperature of the tire, and it is easy to cause the tire to deform if it is picked up immediately by machinery. The air cooling method not only wastes the heat energy of the tire surface, but also contains a large amount of harmful substances in the exhausted gas, which will pollute the atmosphere
