一种氮气风吹电加热橡胶轮胎硫化成型工艺及装置 技术领域
本发明属于硫化装置及硫化工艺领域，特别涉及一种氮气风吹电加热橡胶轮胎硫化成型工艺及装置。
背景技术
目前，国内外橡胶轮胎硫化成型工艺，主要是利用水蒸气和氮气结合实现硫化成型。制备蒸气主要通过燃烧大量煤碳的锅炉制备产生，然后通过管道传输到硫化成型设备，如此在生产传输过程中排放大量CO2、S02等废气污染空气，蒸气的管道在长期使用中损耗也大；在轮胎硫化过程中蒸汽与氮气混合，造成高温高压下的氮气不纯，而使胶囊和轮胎亦存在过氧老化问题，氮气里含有大量水，所以氮气地重复利用率低，相对提高生产成本，因此该硫化工艺及装置硫化过程不环保、生产成本高。也有一些企业采用电加热橡胶轮胎硫化成型工艺代替水蒸气和氮气加热橡胶轮胎，如此产生另一种缺点：上加热板、下加热板及模套加热不均匀，离发热线圈近的温度高，远的温度低；上环中心机构成型内囊采用高热传导率金属片制作，通过机械机构向胎胚内壁施加挤压成型力，不能保证橡胶轮胎内壁各处受力均匀，同时金属成型内囊不通用，对不同规格型号的橡胶轮胎硫化就需匹配对应规格形状的金属成型内囊，增加工业化批量生产成本；采用热氮硫化橡胶轮胎成型工艺，由于氮气的比热容较低，而橡胶轮胎硫化成型单位时间内所需大量热能，采用热氮不能满足橡胶轮胎的硫化成型工艺要求。因此，对于本领域技术人员而言，发明一种环保、高效的橡胶轮胎硫化成型装置及其工艺十分必要。
名称为“热氮硫化轮胎的方法及设备”的现有专利公开一种热氮硫化轮胎的方法，包括轮胎硫化过程，在轮胎硫化时，直接向硫化机或硫化罐的轮胎模具内的胶囊充入加热、加压后的纯氮气。该发明由于避免轮胎硫化过程中压力 与温度的骤升、骤降而对轮胎内部结构造成的损害所以提高硫化轮胎质量，轮胎硫化的压力与温度的连续性好，延长胶囊的使用寿命，提高劳动生产率降低生产成本，有利于环保，使用范围广。但是该方法仍然是采用热氮硫化橡胶轮胎内壁的工艺，在工业上采用该方法进行橡胶轮胎的硫化成型不实用，硫化效率不高，硫化效果不好。
发明内容
为解决上述问题，本发明的目的在于提供一种氮气风吹电加热橡胶轮胎硫化成型装置，氮气风吹电加热模具套对橡胶轮胎外表面均匀加热硫化，利用输氮装置向发热芯氮气风吹硫化装置输入氮气，通过氮气风吹将发热芯的热量带入硫化密闭空间对橡胶轮胎内表面均匀加热，如此实现对橡胶轮胎外表面与内表面同时加热硫化，加热均匀，硫化效率高，硫化效果好。
本发明的另一个目的在于提供一种利用氮气风吹电加热橡胶轮胎硫化成型装置实现硫化的加工工艺，与智能温控系统、智能压力调控系统连接，发热线圈和发热芯采用电加热，可实时调控温度、氮气气压，控制硫化过程中的温度及压力，提高硫化效率，且氮气还可回收进行循环使用，生产成本低，生产效率高，节能环保，便于工业化加工。
