Description

[Technical field]

[0001] The utility model relates to a conveyor belt vulcanization system, in particular to a conveyor belt vulcanization system comprising a vulcanization hot plate. [Background technology]

[0002] As a carrier for transporting materials, conveyor belts are widely used in agriculture, industry and transportation to transport various solid block and powder materials or finished products. Conveyor belts are usually composed of reinforcing materials (also called belt cores) and covering rubber. The covering rubber is usually made of rubber materials, and its molding requires a vulcanization process. The vulcanizer is a key equipment in the vulcanization process. Its heating and cooling are usually achieved by passing steam and coolant separately. When the vulcanizer needs to heat up, high-temperature steam is passed through the pipeline; when the vulcanizer needs to cool down, coolant is passed through the pipeline. However, when heating and cooling alternate, high-pressure shocks often occur in the pipeline of the vulcanizer, causing serious damage to the equipment and pipelines. After analysis, it was found that the cause was that the coolant in the pipeline was not completely discharged after cooling. When the hot plate was heated up the next time, high-temperature steam was instantly passed in, and the clean coolant was not discharged, causing the steam to partially condense into water, and the volume suddenly shrank, causing a local vacuum. The surrounding medium impacted here at high speed, making a huge sound and vibration, thereby damaging the equipment and pipelines. This phenomenon is also called the water hammer effect.
