Problems solved by technology

First, a boiler is usually used with multiple vulcanizing machines. Even if only one vulcanizing machine is used for production, the boiler must be turned on, which consumes a lot of energy.
Second, the temperature of the electrically heated nitrogen drops seriously after the heat exchange, and its temperature control is also difficult to adapt to the temperature adjustment at different time intervals, even making the bladder never reach the required temperature for vulcanization, resulting in defects in the final tire vulcanization quality
The third is that steam and nitrogen use the same pipeline through the capsule vulcanizer. During the vulcanization process, the nitrogen will inevitably be mixed with liquid water produced by the steam, which will cause the nitrogen to be impure, and then cause the nitrogen to be heated when it is heated alone. Problems such as temperature and pressure are more difficult to control

Abstract

The invention discloses a vulcanizing machine self-circulation nitrogen heating system and a heating method. The heating system comprises an air supply pipeline, and the air supply pipeline is connected with a low-pressure air inlet device and a high-pressure air inlet device. A radiator, a gas circulating pump and a low-temperature gas heater are sequentially arranged on the gas supply pipeline; a main circulation pipeline and a preheating circulation pipeline which are arranged in parallel are connected between the tail end and the head end of the air supply pipeline, a preheating circulation valve is arranged on the preheating circulation pipeline, and a shaping ventilation pipeline, a high-temperature ventilation pipeline and a low-temperature ventilation pipeline which are arranged in parallel are connected between the head end of the main circulation pipeline and the tail end of the air supply pipeline. A shaping stop valve group is arranged on the shaping ventilation pipeline, a high-temperature stop valve and a high-temperature gas heater are arranged on the high-temperature ventilation pipeline, a low-temperature stop valve is arranged on the low-temperature ventilation pipeline, and a total circulation stop valve is arranged at the tail end of the total circulation pipeline. According to the invention, better temperature and pressure control can be realized, energy waste is reduced, and the vulcanization quality is improved.

Description

technical field [0001] The invention relates to the technical field of bladder vulcanizers, in particular to a self-circulating nitrogen heating system and a heating method for a vulcanizer. Background technique [0002] The bladder vulcanizer uses the molding method to manufacture tires. During the vulcanization process, the bladder is heated by a heating medium, and the outer mold is heated by electric heating. In the traditional capsule vulcanizer, the inside of the capsule is heated by high-temperature steam heated by a boiler. During the entire bladder vulcanization process, different pressures and temperatures of the heating medium need to be adjusted at different times, and the pressure of high-temperature steam, especially the temperature control, is difficult to adapt to this adjustment, so only the initial preheating and heating of the bladder is carried out with steam. , and during normal bladder vulcanization operations, electric heating nitrogen is used for sel...
